BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pipe clamp structure, and more particularly, to a pipe clamp structure that can solve the problems of deformation and an insufficient fixing force of a pipe clamp at the same time by using one movable member.
2. The Prior Arts
Common pipe clamps includes many types, and pipe clamps that can clamp pipes with different diameters and are convenient for assembly and disassembly also include many types. In a common type, two corresponding arc-shaped pieces are placed opposite to each other to form a clamping opening therebetween, and the connecting portions at both ends thereof are connected by fasteners, respectively. When disassembling, only one of the fasteners needs to be loosened.
Another existing pipe clamp, which is very similar to the present invention, has a U-shaped groove with threads on outer surfaces of both sides thereof and a cover with inner thread therein. When a pipe is placed into the U-shaped groove and the cover is closed, the pipe can be fixed by the pipe clamp by locking tight the corresponding threads of the U-shaped groove and the cover. Such pipe clamp can only be suitable for pipes with constant pipe diameters. For pipes with different pipe diameters, the clamping will be affected. Because only the periphery edge of the cover applies a force to the pipe, the cover and the pipe only contact at two points. As such, the locking force of the cover will act at the two points, thereby resulting in an excessive locking to cause the deformation of the pipe. If the arc of the U-shaped groove is consistent with that of the pipe, the U-shaped groove and the pipe form a curve surface contact, which can increase the friction force between the pipe clamp and the pipe to securely fix together. However, if the arc of the U-shaped groove is inconsistent with that of the pipe, the U-shaped groove and the pipe only form a straight line contact and thus there is less contact between the pipe and the pipe clamp, thereby resulting in an insufficient fixing force. Moreover, since there is no outward supporting structure at an inside of both sides of the U-shaped groove, when rotating the cover, it is easy to squeeze the both sides of the U-shaped groove inward, thereby causing deformation. As such, the corresponding threads of the cover and both sides of the U-shaped groove cannot be engaged with each other. In order to solve the problem of the insufficient fixing force, if such pipe clamp intends to clamp pipes with different pipe diameters, it is necessary to use a plurality of arc auxiliary accessories to match the pipes with different pipe diameters. In order to solve the problem of inward deformation on the both sides of the U-shaped groove, it is necessary to add an anti-deformation structure inside the cover. However, such design still cannot solve the problem of excessive locking or deformation of the pipe caused by the connection of the cover and the pipe at only two positions. In addition, such design also cannot solve the problem of inward deformation on the both sides of the U-shaped groove caused during rotating the cover, and the anti-deformation structure inside the cover will decrease the production efficiency.
Similarly, yet another existing pipe clamp includes a U-shaped groove with threads on outer surfaces at both sides thereof and a cover with inner threads, and further includes a circular disk piece. One side of the circular disk piece has an arc surface with a large arc, and two opposite arc openings are provided on a periphery edge of the circular disk piece. A pipe is placed into the U-shaped groove, the arc surface of the circular disk piece faces toward the U-shaped groove, the arc openings of the circular disk piece are respectively sleeved on both sides of the U-shaped groove, and the cover is placed thereon. By locking tight the corresponding threads of the U-shaped groove and the cover, the edge of the cover will push the periphery edge of the circular disk piece, and the arc surface of the circular disk piece will push toward the pipe to abut against the U-shaped groove to clamp the pipe. Such pipe clamp has the disadvantages that the size of the arc opening determines the pipe diameter range of the suitable pipes. The smaller the arc opening is, when the circular disk piece is close to a bottom of the U-shaped groove, it will be limited by the arc of the bottom, such that the circular disk piece cannot be further pushed forward, and the pipe diameter range of the pipe clamped by the pipe clamp becomes smaller. Also, if there are some protrusions on the pipe and the protrusions face the circular disk piece, when the pipe clamp is locked excessively, the center of the circular disk piece is blocked and cannot be pushed forward, while the cover acts on the periphery edge of the circular disk piece and continues to be pushed forward, thereby causing the deformation of the circular disk piece. In addition, such existing pipe clamp uses the periphery edge of the cover to apply force on the circular disc piece. Since there is no outward supporting structure at inside of the both sides of the U-shaped groove, it cannot solve the problem of inward deformation on the both sides of the U-shaped groove caused during rotating the cover.
The above two existing pipe clamps with a U-shaped groove have provided the corresponding solutions to the problems caused by these types of pipe clamp. The existing problems can be solved by just combining their solutions. However, it is needed to use a plurality of parts or structures, which may cause inconvenience in use or waste of resources.
SUMMARY OF THE INVENTION
In order to overcome the problems of inward deformation on both sides of the existing U-shaped grooved pipe clamp and an insufficient fixing force caused by insufficient contact area between the pipe clamp and the pipe, the present invention provides a pipe clamp structure including a first U-shaped groove, a first movable member, and a first rotating member. The first movable member is provided with a first movable U-shaped groove. The pipe is placed into the first U-shaped groove, the first movable member is inserted into the first U-shaped groove, the first rotating member is pushed toward the first movable member, and the first movable U-shaped groove is pushed toward the pipe, such that the first U-shaped groove and the first movable U-shaped groove clamp tight the pipe. Such pipe clamp structure solves the problems of inward deformation on both sides of the existing U-shaped groove pipe clamp and an insufficient fixing force caused by insufficient contact area between the pipe clamp and the pipe at the same time by using the first movable member.
The technical solution adopted by the present invention to solve the technical problems is to provide a pipe clamp structure for clamping a pipe, comprising a first cylindrical base, a first movable member, and a first rotating member. The first cylindrical base has a first end circular surface, a second end circular surface, and a first cylindrical side surface. The first cylindrical base is provided with a first U-shaped groove along a direction from the second end circular surface toward the first end circular surface. The first U-shaped groove transversely penetrates the first cylindrical base and forms a first opening at the second end circular surface. The first cylindrical side surface is provided with a first thread at an outside thereof. The first movable member has a first end and a second end. The first end is provided with a first movable U-shaped groove along a direction toward the second end. The first end is embedded into the first U-shaped groove through the first opening and the first movable member is closely adjacent to both sides of the first U-shaped groove, and the first end and the both sides of the first U-shaped groove are slidable with each other. The first rotating member has a first cylindrical accommodating part. The first cylindrical accommodating part is provided with a second opening, a second thread, and a first bottom portion. The second end of the first movable member is accommodated in the first cylindrical accommodating part and adjacent to the first bottom portion. The pipe is placed into the first U-shaped groove through the first opening, such that the first movable U-shaped groove of the first movable member faces a direction toward the first opening and is coupled with the first cylindrical base. A first clamping space is formed between the first U-shaped groove and the first movable U-shaped groove. The first cylindrical accommodating part is sleeved at the outside of the first cylindrical side surface along the direction toward the first opening. The first thread and the second thread are engaged with each other. By locking tight the first thread and the second thread, the first bottom portion pushes the first movable member toward the first U-shaped groove, and the first clamping space is reduced to clamp tight the pipe. By loosening the first thread and the second thread, the first bottom portion and the first movable member are pushed backward, and the first clamping space becomes larger to loosen the pipe, such that the pipe can be slidable in the first clamping space, so as to adjust a position of the pipe.
Preferably, the both sides of the first U-shaped groove of the first cylindrical base are formed with two first arc concave portions corresponding to an arc of the first cylindrical base. Each of the first arc concave portions extends longitudinally to the second end circular surface. The first movable member is formed with two first arc convex portions corresponding to the two first arc concave portions. The first cylindrical base and the first movable member are coupled with each other, such that the two first arc concave portions are embedded with the two first arc convex portions, respectively.
Preferably, the second end of the first movable member and the first cylindrical accommodating part are provided with a first snap structure. The first snap structure allows the first movable member and the first cylindrical accommodating part to be coupled with each other and rotatable with each other.
Preferably, a fastener is provided at a predetermined position of the first end circular surface.
Preferably, the fastener is a long screw. A transverse groove is provided at another predetermined position of the first end circular surface. The long screw is provided with a nut knob. A bottom of the nut knob covers at least a part of the transverse groove. An object is placed in the transverse groove, and when the nut knob and the long screw are in a tight-locked state, the object is fixed in the transverse groove.
Preferably, a plurality of first barb members protrude from the first end circular surface. Each of the first barb members has a first upright portion and a first barb portion. The plurality of first barb members are arranged as a first annular structure centered on a center of the first end circular surface. Each of the first barb portions faces toward a radial direction.
Preferably, a first cylindrical recess is provided at a center of a bottom of the first U-shaped groove toward the first end circular surface. A first circular coupling opening is provided at a center of a bottom surface of the first cylindrical recess. A diameter of the first circular coupling opening is smaller than that of the first cylindrical recess.
Preferably, a first cylindrical coupling member is further provided. One end of the first cylindrical coupling member is accommodated in the first cylindrical recess, and penetrates the first circular coupling opening. Another end of the first cylindrical coupling member is provided with a first inner concave arc. The first inner concave arc is corresponding to a curvature and a position of an arc of the bottom of the first U-shaped groove.
Preferably, the pipe clamp structure further includes an extending part. The first cylindrical base is connected to a predetermined position of the extending part.
Preferably, the first end circular surface of the first cylindrical base has one of an arc surface shape, an ellipse-like shape, a square shape and a geometric polygon shape.
The beneficial effect of the present invention is that since the first movable member of the present invention can not only withstand a force due to the inward deformation on both sides of the first U-shaped groove when locking the first rotating member, but also be pushed by the first rotating member toward the pipe, by using the first movable U-shaped groove to increase the contact area with the pipe, the problems of inward deformation on both sides of the U-shaped groove pipe clamp and an insufficient fixing force caused by insufficient contact area between the pipe clamp and the pipe can be solved at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.
Hereinafter, embodiments of the present invention will be described according to FIGS. 1A to 14. This description is not intended to limit the embodiments of the present invention, but is one of the embodiments of the present invention.
As shown in FIGS. 1A to 2B, a pipe clamp structure 1 for clamping a first pipe 4 according to embodiment 1 of the present invention includes a first cylindrical base 11, a first movable member 12, and a first rotating member 13. The first cylindrical base 11 has a first end circular surface 111, a second end circular surface 112, and a first cylindrical side surface 113. The first cylindrical base 11 is provided with a first U-shaped groove 114 along a direction from the second end circular surface 112 toward the first end circular surface 111. The first U-shaped groove 114 transversely penetrates the first cylindrical base 11 and forms a first opening 1141 at the second end circular surface 112. The first cylindrical side surface 113 is provided with a first thread 1131 at an outside thereof. The first movable member 12 has a first end 121 and a second end 122. The first end 121 is provided with a first movable U-shaped groove 123 along a direction toward the second end 122. The first end 121 can be embedded into the first U-shaped groove 114 through the first opening 1141 and the first movable member 12 is closely adjacent to both sides of the first U-shaped groove 114, and the first movable member 12 and the both sides of the first U-shaped groove 114 are slidable with each other. The first rotating member 13 has a first cylindrical accommodating part 131. The first cylindrical accommodating part 131 is provided with a second opening 1311, a second thread 1312, and a first bottom portion 1313. The second end 122 of the first movable member 12 can be accommodated in the first cylindrical accommodating part 131 and adjacent to the first bottom portion 1313. The first pipe 4 is placed into the first U-shaped groove 114 through the first opening 1141, such that the first movable U-shaped groove 123 of the first movable member 12 faces a direction toward the first opening 1141 and is coupled with the first cylindrical base 11. A first clamping space 14 is formed between the first U-shaped groove 114 and the first movable U-shaped groove 123. The first cylindrical accommodating part 131 is sleeved at the outside of the first cylindrical side surface 113 along the direction toward the first opening 1141. The first thread 1131 and the second thread 1312 are engaged with each other. By locking tight the first thread 1131 and the second thread 1312, the first bottom portion 1313 pushes the first movable member 12 toward the first U-shaped groove 114, and the first clamping space 14 is reduced to clamp tight the first pipe 4. By loosening the first thread 1131 and the second thread 1312, the first bottom portion 1313 and the first movable member 12 are pushed backward, and the first clamping space 14 becomes larger to loosen the first pipe 4, such that the first pipe 4 can slide in the first clamping space 14, so as to adjust a position of the first pipe 4. In embodiment 1 of the present invention, the first movable member 12 is provided inside the first U-shaped groove 114, thereby can prevent the problem of deformation of both sides of the first U-shaped groove 114. In addition, since the second end 122 is adjacent to the first bottom portion 1313, by pushing the first bottom portion 1313 toward the second end 122, the first clamping space 14 becomes smaller, such that the purpose of fixing the pipe clamp structure of embodiment 1 and the first pipe 4 with each other can be achieved. In the present invention, the problems of the existing pipe clamp structure can be solved by only using one first movable member 12.
The first U-shaped groove 114 and the first movable U-shaped groove 123 of embodiment 1 may also be V-shaped grooves or other shapes with larger or smaller arc.

Please refer to FIGS. 10A to 10C, which show embodiment 11 of the present invention combining embodiments 9 and 10. As shown in FIG. 10A (also refer to FIGS. 8A, 8B, 9A and 9B), the third end circular surface 211 and the fifth end circular surface 311 face each other, and the second barb member 261 penetrates into the second circular coupling opening 361. Since the outer diameter of the second barb portion 2612 is larger than the second circular coupling opening 361, in the second cylindrical recess 36, the second barb portions 2612 hook the periphery edge of the second circular coupling opening 361, such that the second cylindrical base 21 and the third cylindrical base 31 are coupled with each other by the second barb member 261 and are rotatable with each other. The second cylindrical coupling member 37 is inserted into the second annular structure 26 from the bottom of the third U-shaped groove 314, such that the second barb member 261 is limited in the third cylindrical base 31 and cannot escape. The second inner concave arc 371 is corresponding to the curvature and position of the arc of the bottom of the third U-shaped groove 314. As shown in FIG. 10B, the third pipe 6 is placed into the third U-shaped groove 314 through the fifth opening 3141, such that the third movable U-shaped groove 323 of the third movable member 32 faces a direction toward the fifth opening 3141 and is coupled with the third cylindrical base 31. The third clamping space 34 is formed between the third movable U-shaped groove 323 and the third U-shaped groove 314 as well as the second inner concave arc 371. The third cylindrical accommodating part 331 is sleeved at the outside of the third cylindrical side surface 313 along the direction toward the fifth opening 3141. The fifth thread 3131 and the sixth thread 3312 are engaged with each other. By locking tight the fifth thread 3131 and the sixth thread 3312, the third bottom portion 3313 pushes the third movable member 32 toward the third U-shaped groove 314, and the third clamping space 34 is reduced, such that the second inner concave arc 371 and the third movable U-shaped groove 323 clamp tight the third pipe 6, and the second cylindrical coupling member 37 abuts against the third end circular surface 211, thereby the second cylindrical base 21 and the third cylindrical base 31 are not rotatable with each other. By loosening the fifth thread 3131 and the sixth thread 3312, the third bottom portion 3313 and the third movable member 32 are pushed backward, and the third clamping space 34 becomes larger to loosen the third pipe 6, such that the third pipe 6 can slide in the third clamping space 34, and the second cylindrical coupling member 37 and the third end circular surface 211 are separated, thereby the second cylindrical base 21 and the third cylindrical base 31 are rotatable with each other, so as to adjust the relative position and angle of the third pipe 6 and the second pipe 5 as shown in FIG. 10C. This embodiment combines both embodiments 9 and 10 to form a set of pipe clamp structure that can control the relative position and angle of the two pipes.
