The first adjusting device 44 comprises a first adjusting member 54 and a first base 56. The first adjusting member 54 is configured to adjust the first base 56.
Specifically, the first base 56 comprises a first part 58 and a second part 60. The second part 60 is connected to the first part 58. Preferably, the first part 58 and the second part 60 are integrally formed in one piece. For example, the first part 58 and the second part 60 form a supporting plate which has a length L. A longitudinal direction of the supporting plate is substantially identical to a longitudinal direction (or a longitudinally moving direction) of the second rail 40. In other words, the first part 58 and the second part 60 are extended along the longitudinal direction of the second rail 40. Preferably, the first base 56 further comprises an extension wall 62 substantially perpendicularly connected to the second part 60. Preferably, the extension wall 62, the second part 60 and the first part 58 are integrally formed in one piece. Preferably, the first base 56 is flexible. For example, the first base 56 is made of metal or plastic.
The first adjusting member 54 comprises a main body part 64, an eccentric part 66 and an operating part. 68. The main body part 64 is substantially in a circular shape. The eccentric part 66 is arranged on the main body part 64. The eccentric part 66 and the main body part 64 have different circle centers (not concentric). The main body part 64 can penetrate through an opening 70 of the middle plate 52c of the housing 52, in order to allow the eccentric part 66 to be mounted to the extension wall 62 of the first base 56, such that the first base 56 can be adjusted to move by the first adjusting member 54.
Preferably, the extension wall 62 of the first base 56 has a connecting hole 72 corresponding to the eccentric part 66 of the first adjusting member 54. A width w of the connecting hole 72 is slightly greater than an outer diameter of the eccentric part 66 of the first adjusting member 54. In the present embodiment, the connecting hole 72 can be an elongated hole. Preferably, a connecting member 74 can be arranged on the extension wall 62 of the first base 56 by passing through the connecting hole 72. The connecting member 74 has a first connecting part 74a and a second connecting part 74b connected to the first connecting part 74a. An outer diameter of the first connecting part 74a is greater than a height h of the connecting hole 72, such that the first connecting part 74a is located outside the connecting hole 72 while being mounted to the first base 56. An outer diameter of the second connecting part 74b is smaller than the height h of the connecting hole 72, such that the second connecting part 74b can penetrate through the connecting hole 72 to be connected to the eccentric part 66 of the first adjusting member 54. The operating part 68 is connected to the main body part 64.
Preferably, after the main body part 64 penetrating through the opening 70 of the housing 52, the main body part 64 can be further connected to the second connecting part 74b of the connecting member 74 through a mounting plate 76. Wherein, the mounting plate 76 is slightly larger than the main body part 64, and the mounting plate 76 is arranged between the main body part 64 and the extension wall 62.
Preferably, at least one first feature 78 and at least one second feature 80 corresponding to the at least, one first feature 78 are arranged between the main body part 64 of the first adjusting member 54 and the housing 52. In the present embodiment, a plurality of first features 78 are arranged on a periphery of the main body part 64, and two second features 80 are arranged on the middle plate 52c of the housing 52. The first features 78 and the second features 80 can be a combination of concave and convex structures, or a combination of convex and concave structures. When the first adjusting member 54 is adjusted to rotate, one of the plurality of first features 78 can be engaged with the second feature 80, such that the first adjusting member 54 can be temporarily positioned relative to the housing 52 after rotation.
On the other hand, the second adjusting device 50 comprises a second adjusting member 82 and a second base 84. The second adjusting member 82 is configured to adjust the second base 84 to move along a transverse direction T relative to the second rail 40 or the first base 56. In other words, the second adjusting member 82 can adjust a transverse position of the second base 84. Preferably, the second base 84 is flexible. For example, the second base 84 is made of metal or plastic.
Specifically, the second base 84 comprises a base part 86 and a protrusion part 88. The protrusion part 88 is fixed relative to the base part 86. The protrusion part 88 is arranged along a longitudinal direction of the first base 56. For example, the protrusion part 88 can be riveted to the base part 66 by a rivet 89 (as shown in
The second adjusting member 82 can be operatively connected to the second base 84. The second base 84 (the base part 86) and the second adjusting member 82 respectively have a first adjusting structure 98 and a second adjusting structure 100 corresponding to each other.
For example, the first adjusting structure 98 and the second adjusting structure 100 are screw structures screwed to each other. Through interaction between the first adjusting structure 98 and the second adjusting structure 100, the second adjusting member 82 can adjust the second base 84 to move along the transverse direction T.
As shown in
As shown in
During an installation process of the drawer 24, a user can use the second adjusting member 82 to adjust the transverse position of the second base 84, in order to align the protrusion part 88 of the second base 84 to the mounting hole 34 of the rear wall 28 of the drawer 24 (or the carried object). Furthermore, when the drawer 24 is mounted to the second rail 40, the protrusion part 88 of the second base 81 to inserted into the mounting hole 31 of the rear wall 28 of the drawer 24, and the second part 60 is configured to support the bottom of the drawer 24.
As shown in
As shown in
Specifically, in the present embodiment, since the first part 58 is fixedly connected to the second rail 40, the inclination angle of the second part 60 relative to the second rail 40 can be adjusted when the user operates the first adjusting member 54 to rotate along the rotation direction R. For example, the inclination angle of the second part 60 relative to the second rail 40 can be adjusted to a first inclination angle A1. In other words, the rear wall 28 of the drawer 24 is obliquely lifted, such that the inclination angle of the drawer 24 is adjusted. Wherein, an inner wall 35 of the mounting hole 34 of the drawer 24 is moved closer to the protrusion part 88 of the second base 84.
As shown in
As shown in
Specifically, in the present embodiment, since the first part 58 is fixedly connected to the second rail 40, the inclination angle of the second part 60 relative to the second rail 40 can be further adjusted when the user operates the first adjusting member 54 to further rotate along the rotation direction R. In other words, the rear wall 28 of the drawer 24 is further obliquely lifted, such that the inclination angle of the drawer 24 is adjusted. Wherein, the inner wall 35 of the mounting whole 34 of the drawer 24 is moved further closer to the protrusion part 88 of the second base 84.
Moreover, dimensional tolerances of the mounting hole 34 of the drawer 24 and the protrusion part 88 of the second base 84 may cause two situations. In a first situation, the inner wall 35 of the mounting hole 34 of the drawer 24 may contact the protrusion part 88 of the second base 84. Wherein, since the protrusion part 88 of the second base 84 is fixedly connected to the base part 86, the protrusion part 88 is not moved by the inner wall 35. Or, in a second situation, when a force applied by the user to the first adjusting member 54 is too large, a force applied to the protrusion part 88 from the inner wall 35 may deform the protrusion part 88 to slightly tilt. Therefore, through fixedly connecting the protrusion part 88 to the base part 86, the position of the protrusion part 88 is not easily changed by an external force, so as to increase structural reliability.
The slide rail mechanism and the adjusting assembly for slide rail of the present in are characterized in that:
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
