The invention relates to the technical field of fixing devices, particularly a thread fixing base and a quick fixing structure.
The most commonly used fixing method is to use multiple bolt ends to tighten the components to be fixed. To enhance the fixation strength, the bolt end is generally long, so it takes a long time to rotate the thread when fixing or loosening the component to be fixed, resulting in low installation efficiency.
For example, the Christmas tree base on the market is equipped with a thread clamping device to fix the tree trunk, and four long screws are used to clamp the Christmas tree trunk by rotating and tightening. But fixing or loosening the Christmas tree is time-consuming and labor-intensive, and it takes a long time to rotate the screw.
Therefore, the applicant discloses a thread fitting component and a quick fixing structure (application number CN2020201243961). The quick fixing structure comprises a first fitting part, a second fitting part and a thread part, wherein the first fitting part comprises a first non-complete thread groove. The second fitting part and the first fitting part can be unlocked and locked, and a second non-complete thread groove is also comprised. The first non-complete thread groove and the second non-complete thread groove form a complete screw hole when the second fitting part and the first fitting part are locked. The coordinated movement of thread parts and thread fitting components can quickly tighten and disassemble the object to be fixed. On the basis of ensuring fixing strength, the quick fixing structure reduces installation time, but the following shortcomings still exist:
In order to be used, the thread part needs to be threaded together with the first and second non-complete thread grooves. Therefore, high accuracy is required for the thread fitting of the first non-complete thread groove, second non-complete thread groove and thread parts, resulting in high manufacturing costs. Meanwhile, due to the fact that the first fitting part is assembled on the base, assembly requires much time. The first fitting part and the second fitting part are used for upper and lower buckling or fixing bolts are used for connection or push-pull parts and grooves mutually fit to lock. This type of structure features a long assembly time and inconvenient unlocking and locking.
In view of above, the invention provides an optimized structure for thread fixing base and quick fixing structure which has less strict requirements for thread assembly accuracy, while improving the convenience of assembly, unlocking and locking of the thread fixing base.
To achieve the above objectives, the invention adopts the following technical solution:
Wherein, the hinge base and the shaft component are hinged to make one side of the top cover and one side of the base rotatable to fit; the buckle plate and the buckle groove are buckled to make the other side of the top cover and the other side of the base able to be unlocked and locked. When the top cover and the base are locked, the thread groove and the limit top plate jointly form a screw hole that matches the thread rod. When the top cover and the base are unlocked, and the thread groove and the limit top plate are far away from each other, the thread rod can be taken out of the thread groove or placed inside the thread groove.
To better achieve the above technical solution, optionally, the cross section of the thread groove is semi-circular.
Optionally, the hinge base comprises a pair of hinge side ears fixing at both ends on one side of the base, and the opposite side walls of the pair of hinge side ears are provided with coaxial hinge holes; the shaft component comprises a rotating part fixing on one side of the top cover, and opposite sides of the rotating part are respectively provided with shaft holes. Each shaft hole can be equipped with a hinge shaft in a retraction way. The first end of the hinge shaft is connected to the bottom of the shaft hole, and the second end of the hinge shaft is clamped into the hinge hole to connect the hinge side ears with to the shaft component.
Optionally, the end face of the second end of the hinge shaft is an inclined plane.
Optionally, one side of the base set with the buckle groove is also provided with a snap bulge, and the top cover is provided with a snap groove that is in interference fit with the snap bulge.
Optionally, the buckle plate is in an inverted T-shaped structure, the upper vertical part of the buckle plate is fixedly connected with the center of one side of the top cover, the end of the lower transverse part of the buckle plate facing the base is a locking part, the locking part is in interference fit with the buckle groove, and the lower transverse part of the buckle plate is away from the end of the base to form an unlocking part.
Optionally, the top cover is equipped with a plurality of reinforcing plates fixedly connected to the limit top plate.
Optionally, the top cover has a hollow structure inside.
