Background technique

For example, US Patent No. US 8,911,037B2 discloses a bracket. The bracket is used for installing a drawer slide rail to a main board of a cabinet wall. The main board has an upper flange, a lower flange, a recess arranged between the upper flange and the lower flange, and a slope extending between an edge of the recess and the recess. Wherein, the main board can be installed to the cabinet wall, and the bracket is attached to the drawer slide rail. The upper flange and the lower flange of the main board can be used to buckle an upper edge and a lower edge of the bracket. The recess of the main board can be used to accommodate a protrusion of the bracket, so that the bracket can be adjusted horizontally relative to the main board in the recess through the protrusion.

However, since the lug of said patent is continuously connected to a plate portion of the bracket, the lug cannot move relative to the plate portion of the bracket (in other words, the lug is not movable relative to the plate portion of the bracket). is fixed) and it is not easy to install the bracket to the motherboard. Therefore, as market demands vary, how to develop a different connection product so that the market has more choices has become an issue that cannot be ignored.

2. After the bracket 24 and the base 22 are installed with each other, the bracket 24 and the base 22 can move relative to each other. For example, the bracket 24 can be horizontally adjusted relative to the base 22 (towards the first direction D1 or the second direction D2).

3. The bracket 22 can be mounted to the base 22 from the first side 34a of the base 22 toward the first direction D1 toward the second side 34b through the first edge E1; or, the bracket 24 can also be mounted to the base 22 through The second edge E2 is installed on the base 22 from the second side 34b of the base 22 toward the second direction D2 towards the first side 34a. Accordingly, it has the function that both directions can be installed.

4. The first elastic portion 42 of the bracket 24 can be installed into the first movable space S1 of the base 22 , and the second elastic portion 44 of the bracket 24 can be installed into the second elastic portion of the base 22 . In the event space S2. Wherein, the end 42b of the first elastic portion 42 passing through the bracket 24 can be blocked by the first limiting structure B1 of the base 22 , and the end 44b of the second elastic portion 44 passing through the bracket 24 It can be blocked by the second limiting structure B2 of the base 22 , so that the bracket 24 can only move horizontally within a limited range relative to the base 22 .

5. The second elastic portion 44 and the first elastic portion 42 are respectively located adjacent to the upper portion 36 and the lower portion 38 of the bracket 24 .

Although the present invention has been described with reference to the current specific embodiments, those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present invention, and other modifications can be made without departing from the spirit of the present invention. Various equivalent changes and modifications, therefore, as long as the changes and modifications to the above embodiments are within the true spirit of the present invention, they will all fall within the scope of the claims of the present application.
