Description

Technical Field

[0001] The utility model belongs to the technical field of slide rails and relates to a self-locking slide rail device. Background Art

[0002] Slides, also known as guide rails or runners, are hardware components fixed to the cabinet body of furniture to allow drawers or panels to move in and out. Self-locking slides automatically retract and lock when about to return to their original position. Existing self-locking slides typically have some room to move even after locking and require only a small amount of force to open. Therefore, to prevent young children from opening drawers and accessing dangerous items inside, the design of a self-locking slide is essential. Summary of the Invention

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose a self-locking slide rail device.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a self-locking slide rail device, including a main slide rail, which is slidably installed on a fixed slide rail, and is characterized in that a magnetic block 1 is installed at the end of the main slide rail, and a magnetic block 2 that attracts each other is provided at a horizontal corresponding position of the magnetic block 1, and a card slot is provided at the bottom of one end of the magnetic block on the main slide rail, and a linkage rod is provided below the main slide rail, and the middle position of the linkage rod is fixed by a fixed shaft, and one end of the linkage rod is connected to a buffer spring, which is installed at a position below the main slide rail through a mounting seat, and the other end of the linkage rod is provided with a protrusion that cooperates with the card slot.

[0005] The working principle of the utility model is as follows: the fixed slide rail is installed on the cabinet body, and the main slide rail is installed on both sides of the drawer. When we close the drawer, the main slide rail slides toward the direction of the second magnetic block. When the first magnetic block approaches the second magnetic block, they attract each other and the protrusion is locked in the slot under the action of the magnetic force; when we need to pull out the drawer, we first press one end of the linkage rod, and under the transmission action of the linkage rod, the protrusion is separated from the slot to unlock, and then the drawer is pulled out.

[0006] A cross bar is installed at the end of the linkage rod.

[0007] The above structure is adopted to facilitate pressing when unlocking.

[0008] In an initial state, the protrusion is flush with the height of the slot.

[0009] With the above structure, a certain buffering force is provided when the main slide rail moves rapidly.

[0010] The protrusion, the first magnetic block and the second magnetic block are all provided with chamfers.

[0011] The above structure is adopted for easy insertion and adsorption.

[0012] The main slide rail is provided with a mounting hole.

[0013] The above structure is used to fix the main slide rail and the drawer.

[0014] Compared with the existing technology, this self-locking slide rail device has the following advantages: this new type adds passive locking and active unlocking structures on the basis of the traditional magnetic structure, so that the slide rail is completely locked after being locked, effectively preventing younger children from opening the drawer at will.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-2 As shown, the self-locking slide rail device includes a main slide rail 1, which is slidably installed on the fixed slide rail 2. A magnetic block 3 is installed at the end of the main slide rail 1, and a magnetic block 2 4 that attracts each other is provided at a horizontal corresponding position of the magnetic block 3. A card slot 5 is provided at the bottom of the end of the magnetic block 3 on the main slide rail 1, and a linkage rod 6 is provided below the main slide rail 1. The middle position of the linkage rod 6 is fixed by a fixed shaft 7. One end of the linkage rod 6 is connected to a buffer spring 8, and the buffer spring 8 is installed at the position below the main slide rail 1 through a mounting seat 9. The other end of the linkage rod 6 is provided with a protrusion 10 that cooperates with the card slot 5.

[0020] In the utility model, the magnetic block 2 4 is installed on the cabinet through the existing structure.

[0021] In the present invention, the length from the buffer spring 8 to the fixed shaft 7 is greater than the length of the protrusion 10 with the fixed shaft 7, which makes unlocking more labor-saving.

[0022] The main structures of the utility model are arranged on both sides of the drawer.

[0023] The buffer spring 8 in the present invention not only plays a buffering role but also plays a role in limiting and positioning the linkage rod 6 .

[0024] A cross bar 11 is installed at the end of the linkage rod 6 .

[0025] In an initial state, the protrusion 10 is flush with the slot 5 .

[0026] The protrusion 10, the magnetic block 1 3 and the magnetic block 2 4 are all provided with chamfers.

[0027] In the present invention, the surface of the protrusion 10 is provided with a wear-resistant coating.

[0028] The main slide rail 1 is provided with a mounting hole 12 .

[0029] The working principle of the present invention is as follows: the fixed slide rail 2 is installed on the cabinet body, and the main slide rail 1 is installed on both sides of the drawer. When we close the drawer, the main slide rail 1 slides toward the direction of the magnetic block 2 4. When the magnetic block 1 3 approaches the magnetic block 2 4, they attract each other and the protrusion 10 is locked in the card slot 5 under the action of the magnetic force; when we need to pull out the drawer, we first press one end of the linkage rod 6, and under the transmission action of the linkage rod 6, the protrusion 10 is separated from the card slot 5 to unlock it, and then the drawer is pulled out.

[0030] The various mechanisms in the utility model are connected and driven by using existing technologies.

[0031] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
