Description

Technical Field

[0001] The utility model relates to a self-locking structure for a drawer slide rail. Background Art

[0002] A drawer slide rail is a connecting component for connecting a cabinet body and a drawer. Under the action of the drawer slide rail, the drawer can be pulled out or pushed into the cabinet body relative to the cabinet. For existing slide rails without a damper, when the cabinet is tilted or under other acting forces, the drawer will automatically slide out, especially during handling or transportation. This is because the existing ordinary slide rails do not have a self-locking structure, resulting in the moving rail sliding randomly under the action of external forces. Further improvement is needed. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a self-locking structure for a drawer slide rail.

[0004] A self-locking structure for a drawer slide rail designed according to this purpose includes a fixed rail and a moving rail slidably arranged on the fixed rail. The moving rail can reciprocally slide between a first position and a second position relative to the fixed rail. A first positioning element is arranged on the fixed rail, and a second positioning element is arranged on the moving rail.

[0005] When the moving rail is in the first position, the first positioning element and the second positioning element are in positioning cooperation to restrict the sliding of the moving rail relative to the fixed rail.

[0006] Preferably, a positioning groove is arranged on the first positioning element, and a positioning protrusion is arranged on the second positioning element.

[0007] When the moving rail is in the first position, the positioning protrusion is embedded in the positioning groove to restrict the sliding of the moving rail relative to the fixed rail.

[0008] Preferably, an extension piece is arranged on the second positioning element, and the positioning protrusion is arranged on the extension piece.

[0009] Preferably, the first positioning element is made of soft rubber.

[0010] Preferably, the first positioning element is provided with an installation groove penetrating up and down, and the fixed rail is provided with a fixing socket extending upward.

[0011] The fixing socket and the installation groove are in interference plug-in fit.

[0012] Preferably, anti-detachment protrusions abutting against the first positioning element are respectively arranged on the left and right of the upper end of the fixing socket.

[0013] Compared with the prior art, a first positioning element is provided on the fixed rail, and a second positioning element is provided on the moving rail; when the moving rail is in the first position, the first positioning element and the second positioning element are in positioning cooperation to restrict the sliding of the moving rail relative to the fixed rail. In the present utility model, when the moving rail is in the first position, the cooperation between the first positioning element and the second positioning element can restrict the sliding of the moving rail relative to the fixed rail, so as to prevent the drawer from being randomly opened due to the random sliding of the moving rail.

[0022] The present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Referring to Figures 1 - 8 , a self-locking structure for a drawer slide rail includes a fixed rail 10 and a moving rail 20 slidably disposed on the fixed rail 10. The moving rail 20 can reciprocally slide relative to the fixed rail 10 between a first position and a second position. A first positioning element 30 is provided on the fixed rail 10, and a second positioning element 40 is provided on the moving rail 20;

[0024] When the moving rail 20 is in the first position, the first positioning element 30 and the second positioning element 40 are in positioning cooperation to restrict the sliding of the moving rail 20 relative to the fixed rail 10.

[0025] When the moving rail is in the first position, the cooperation between the first positioning element and the second positioning element can restrict the sliding of the moving rail relative to the fixed rail, so as to prevent the drawer from being opened randomly due to the random sliding of the moving rail.

[0026] In use, the fixed rail 10 is connected to the cabinet body, and the moving rail 20 is connected to the drawer. When the moving rail 20 is in the first position, the drawer is in a fully closed state. When the moving rail 20 is in the second position, the drawer is in a fully open state.

[0027] See Figure 3 and Figure 4 , a positioning groove 310 is provided on the first positioning element 30, and a positioning protrusion 410 is provided on the second positioning element 40;

[0028] When the moving rail 20 is in the first position, the positioning protrusion 410 is embedded in the positioning groove 310 to restrict the sliding of the moving rail 20 relative to the fixed rail 10.

[0029] Furthermore, there are two positioning grooves 310, which are respectively arranged on the left and right side walls of the first positioning element 30. There are two positioning protrusions 410. When the moving rail 20 is in the first position, the two positioning protrusions 410 are respectively located on the left and right sides of the first positioning element 30 and are embedded in the corresponding positioning grooves 310.

[0030] See Figure 3 and Figure 4 , an extension piece 400 is provided on the second positioning element 40, and the positioning protrusion 410 is provided on the extension piece 400.

[0031] In the present utility model, the first positioning element 30 is made of soft glue. The first positioning element 30 made of soft glue can deform itself, so as to facilitate the positioning protrusion 410 to be inserted into or separated from the positioning groove 310.

[0032] See Figure 6 and Figure 8 , the first positioning element 30 is provided with an installation groove 300 penetrating up and down, and the fixed rail 10 is provided with an upwardly extending fixed socket 100;

[0033] The fixed socket 100 is in interference plug-in fit with the installation groove 300.

[0034] See Figure 6 and Figure 8 , anti-detachment protrusions 110 that abut against the first positioning element 30 are respectively arranged on the left and right of the upper end of the fixed socket 100. When the fixed socket 100 and the installation groove 300 are assembled by inserting, the anti-detachment protrusions 110 abut against the upper side wall of the installation groove 300, which can restrict their separation.

[0035] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model.
