Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are illustrated in the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete. It should be noted that the terms "first" and "second" in the present invention do not denote any particular quantity or order, but rather are used for distinguishing names.

Referring to fig. 1, in the present embodiment, a function box plug-in mounting structure suitable for a drawer rail includes a function box 2 mounted on the drawer rail, and a person skilled in the art can select the function box 2 with a rebounding function, a self-closing function, a buffering function, etc. according to the function requirement, which is not limited herein specifically, and the structure and principle thereof belong to the conventional technical means, and refer to the function box 2 described in the patents of CNCN108402735B, CN109171265A, etc. Furthermore, the upper rail 1 of the drawer rail is provided with a connecting portion 11, and the connecting portion 11 may also be used as an "upper synchronous rack" as in patent CN113229649A, or may be used only for installing the function box 2 in a matching manner, and is not limited specifically here.

In the present embodiment, the function cartridge 2 is provided with a mounting base 21 (i.e., the function cartridge 2 is pre-mounted on the mounting base 21 by fixing means such as screws and buckles, which is not limited herein); next, the mounting base 21 of the present embodiment is made of sheet metal, and has the characteristics of high strength, light weight, and the like.

In the present embodiment, the connection portion 11 is provided with a caulking groove extending along the drawing direction of the drawer rail, specifically, the outer side wall of the connection portion 11 is formed with a plurality of hooking blocks 113, and a groove is formed between the inner wall of each hooking block 113 and the outer side wall of the connection portion 11, thereby constituting the caulking groove for the sliding insertion of the mounting base 21 by correspondingly distributing the plurality of hooking blocks 113 on both sides.

Further, one side of the mounting base 21 is integrally bent to form a hem which is matched with the caulking groove in a sliding embedded mode, and two sides of the hem are provided with a vacancy avoiding position corresponding to each clamping hook block 113 in a forming mode, so that the hem of the mounting base 21 is prevented from being vertically inserted into the caulking groove through each clamping hook block 113, and then the hem slides along the caulking groove to enable the edge of the hem to be connected to the groove position between each clamping hook block 113 and the mounting base 21 in a sliding mode, and the hem of the mounting base 21 cannot be reversely separated from the caulking groove in a direction perpendicular to the drawing direction.

In this embodiment, the inner wall of the recessed groove (i.e., the outer side wall of the connecting portion 11) is formed with a positioning portion 111 for the flange of the mounting base 21 to be engaged with, wherein the positioning portion 111 of this embodiment is a boss-shaped structure, and the mounting base 21 is provided with a first engaging groove 211 for the positioning portion 111 to be engaged with, specifically, after the flange slides in place along the recessed groove (where the front end of the flange contacts with the end surface of the recessed groove), the corresponding positioning portion 111 is engaged with the first engaging groove 211, so that the positioning portion 111 is used to limit the sliding-out motion of the mounting base 21 relative to the recessed groove, so that the flange of the mounting base 21 cannot easily come out of the recessed groove along the drawing direction of the drawer guide rail without being affected by external force, and thus performing positioning and locking functions.

On the contrary, if the mounting base 21 needs to be detached, the user applies a large reverse acting force to the mounting base 21, so that the mounting base 21 reversely slides relative to the caulking groove, the positioning portion 111 is made to relatively reversely slide and withdraw from the first clamping groove 211, and the positioning portion can be directly and vertically taken out of the caulking groove after the folding edge of the mounting base 21 is kept away from each clamping hook block 113.

Further, in order to facilitate the clamping and matching of the positioning portion 111 and the mounting base 21, the positioning portion 111 of this embodiment is formed with a guiding slope 1111 extending backward to the inner wall of the caulking groove, and the front end portion of the folded edge of the mounting base 21 is formed with a guiding inclined plane 213 extending forward and slidably abutting against the guiding slope 1111, therefore, when the mounting base 21 is slidably mounted forward along the caulking groove, the front end portion of the folded edge of the mounting base 21 and the positioning portion 111 move in opposite directions, so that the guiding inclined plane 213 slidably abuts against the guiding slope 1111, so that the positioning portion 111 can slide relative to the folded edge, until the positioning portion 111 is embedded into the first slot 211.

In this embodiment, due to the fact that there is a collision between the positioning portion 111 and the front end portion of the mounting base 21, the positioning portion 111 is stressed to be broken under some extreme assembly conditions, and thus the positioning portion 111 cannot position and limit the mounting base 21, and therefore, in order to solve this problem, in this embodiment, the elastic arm 112 and the clamping block are added as a spare auxiliary positioning and limiting function, specifically, the elastic arm 112 is formed on the inner wall of the caulking groove in this embodiment, and the clamping block which is in clamping fit with the second clamping groove 212 preset in the mounting base 21 is formed on the elastic arm 112. That is, after the hem relatively slides in place along the caulking groove (here, the front end portion of the hem is in contact with the end face of the caulking groove), the corresponding clamping block is in clamping fit with the second clamping groove 212 to limit the sliding-out action of the mounting base 21 relative to the caulking groove, so that the functions of auxiliary positioning and locking are achieved, and the situation that the mounting base 21 is separated from the connecting portion 11 due to the fact that the positioning block is broken is avoided.

The above-described embodiments are merely preferred embodiments of the present invention, which are not intended to limit the present invention in any way. Those skilled in the art can make many changes, modifications, and equivalents of the embodiments of the invention without departing from the scope of the invention. Therefore, the content of the technical scheme of the utility model, according to the equivalent change made by the idea of the utility model, should be covered in the protection scope of the utility model.
