[0002] A shelf is a common storage solution for home or office space, used to store items and make the space more tidy and orderly. In the prior art, a shelf is usually used in conjunction with rollers, so that the shelf is no longer limited to a fixed position, but can be adjusted at any time as needed, optimizing the space layout and adapting to different usage scenarios.

[0003] A common combination is to install the roller assembly at the four corners of the rack so that the rollers can provide the rack with the best stability and mobility to prevent the rack from tipping over. Usually, the roller assembly includes a roller mounting plate and a roller that can rotate 360° relative to the roller mounting plate, and the rack is provided with a leg at each of the four corners at the bottom, and each leg is combined with a roller assembly and fastened with bolts.

[0004] However, during long-term use, the legs of the rack and the roller mounting plate may rotate relative to each other, which may easily cause the roller assembly to separate from the legs of the rack. At the same time, during long-term use, the roller assembly may be bumped or the fastening bolts are old, which may cause the fastening bolts between the legs and the roller mounting plate to loosen, thereby affecting the stability between the rack and the roller.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] Embodiment 1:

[0038] Embodiment 1 of the present application discloses a rack roller fixed connection structure, referring to Figure 1 and Figure 2The roller fixed connection structure of the storage rack includes a leg 1, a roller 2 and two connecting members 3. The leg 1 is placed vertically, and the leg 1 is distributed at the four corners of the bottom of the storage rack to support the entire storage rack. The leg 1 includes a first support member 11 and a second support member 12, and the first support member 11 is perpendicular to the second support member 12. The roller 2 is located below the leg 1, and there is a one-to-one correspondence between the roller 2 and the leg 1. The top of the roller 2 is rotatably connected to a horizontally placed roller mounting plate 21, and the roller 2 is rotatably connected to the roller mounting plate 21 through a fixed seat 22. The rotation axis of the fixed seat 22 is vertical. The two connecting members 3 are located above the roller 2, and are used to stably connect the leg 1 and the roller 2 together.

[0039] Specifically, each connecting member 3 includes a first connecting portion 31 and a second connecting portion 32, and the first connecting portion 31 is perpendicular to the second connecting portion 32. The first connecting portion 31 extends along the length direction of the leg 1, and the two first connecting portions 31 are respectively located on both sides of the first support member 11, and the second connecting portion 32 is located at the bottom of the first connecting portion 31 and is perpendicular to the first connecting portion 31, and is close to the roller mounting plate 21. During installation, the two first connecting portions 31 clamp the first support member 11 inside and are fixedly connected by fasteners 4. The fasteners 4 can be fastening bolts, and the fasteners 4 can also be used together with locking nuts. The second connecting portion 32 is tightly pressed against the roller mounting plate 21. The fasteners 4 are simultaneously inserted into the first connecting portions 31 of the two connecting members 3, combining the two first connecting portions 31 into a whole.

[0040] Reference Figure 1 and Figure 2 In order to enhance the stability between the two connecting members 3, the first connecting portion 31 is integrally formed with an abutting portion 311 at the edge corresponding to the position of the fastener 4. The abutting portion 311 protrudes inward, and the abutting portions 311 on the two first connecting portions 31 correspond to each other and abut against each other. After the two corresponding abutting portions 311 abut against each other, the shaking between the two connecting members 3 can be effectively reduced, and the connection stability between the connecting member 3 and the leg 1 can be improved. In order to further improve the connection stability between the connecting member 3 and the leg 1, a buffer can be filled in the gap between the two first connecting portions 31. The buffer can be a rubber buffer layer. The buffer itself has a certain elasticity. When the two connecting members 3 are hit by external force, the buffer can effectively absorb part of the impact force, thereby reducing the shaking between the two connecting members 3.

[0041] In order to further improve the connection stability between the connecting member 3 and the supporting leg 1, three positioning protrusions 111 are fixed at intervals on both sides of the first supporting member 11, and the positioning protrusions 111 are distributed in the vertical direction. A positioning groove 312 is provided through the position of the first connecting portion 31 corresponding to the positioning protrusion 111. During installation, the positioning protrusion 111 is correspondingly inserted into the positioning groove 312. The positioning groove 312 provides a positioning function for the positioning protrusion 111 and can also limit the movement of the positioning protrusion 111, so that the positioning protrusion 111 is clamped in the positioning groove 312.

[0042] Reference Figure 1 and Figure 2 The second connecting portion 32 is integrally formed with a first bending portion 321 on both sides thereof. The first bending portion 321 is bent downward and simultaneously toward the inner side of the roller mounting plate 21. The inner side wall of the bent first bending portion 321 is pressed against the roller mounting plate 21, so that the connecting member 3 and the roller mounting plate 21 are tightly combined as a whole. In order to further improve the stability of the roller mounting plate 21, the second connecting portion 32 is also integrally formed with a second bending portion 322 on the other two sides thereof corresponding to the roller mounting plate 21. The second bending portion 322 is bent downward so that the second bending portion 322 is perpendicular to the second connecting portion 32, and the inner side wall of the second bending portion 322 is pressed against the side wall of the roller mounting plate 21, thereby further limiting the position of the roller mounting plate 21. The first bending portion 321 and the second bending portion 322 are both formed by machine pressing during bending, so that the first bending portion 321 and the second bending portion 322 can be closely attached to the side wall of the roller mounting plate 21 .

[0043] The second connection portion 32 is in close contact with the roller mounting plate 21, and the roller mounting plate 21 is clamped and fixed by providing the first bending portion 321 and the second bending portion 322, thereby realizing a stable connection between the connection member 3 and the roller 2. This connection method can connect the leg 1 and the roller 2 without using fasteners 4 such as bolts, is convenient for installation and disassembly, and has high connection stability, which effectively solves the problem of the leg 1 and the roller 2 falling off due to rust of the bolts that may occur in the traditional connection method.

[0044] The implementation principle of the roller fixed connection structure of the storage rack in Example 1 of the present application is as follows: the two first connecting parts 31 clamp and fix the supporting legs 1, and the corresponding abutting parts 311 abut against each other to improve the connection stability between the two connecting members 3. The side surfaces of the second connecting part 32 are respectively provided with a first bending part 321 and a second bending part 322. The first bending part 321 bends inward to clamp the roller mounting plate 21, so that the connecting member 3 and the roller 2 are combined into a whole.

[0045] Embodiment 2:

[0046] The difference between Example 2 and Example 3 is that: Figure 3The end of the first bent portion 321 is bent upward to form a support portion 323, which is bent upward and abuts against the bottom of the roller mounting plate 21, thereby further limiting the freedom of the roller mounting plate 21 to move left and right, making the connection between the roller mounting plate 21 and the connecting member 3 more stable. At the same time, the support portion 323 also abuts against the roller mounting plate 21, which can provide an upward support force for the roller mounting plate 21, effectively reducing the bending deformation of the roller mounting plate 21 when subjected to force.

[0047] Embodiment 3:

[0048] The difference between Example 3 and Example 2 is that: Figure 4 In order to further improve the firmness of the connection between the roller mounting plate 21 and the connecting member 3, a positioning hole 211 is provided on the bottom surface of the roller mounting plate 21 at a position corresponding to the support portion 323, and a positioning column 324 is integrally formed at the end of the support portion 323. When the roller mounting plate 21 and the connecting member 3 are installed, the support portion 323 is bent upward and abutted against the bottom surface of the roller mounting plate 21, and the positioning column 324 is inserted into the positioning hole 211, and the outer wall of the positioning column 324 abuts against the inner side wall of the roller mounting plate 21 at the positioning hole 211, thereby further limiting the sliding of the roller mounting plate 21 relative to the connecting member 3, and improving the tightness of the connection between the roller mounting plate 21 and the connecting member 3.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
