Description

Technical Field

[0001] This utility model relates to the field of drawer cabinet technology, specifically to a linkage locking mechanism between drawers in a cabinet. Background Technology

[0002] The drawer chest has multiple drawers arranged vertically. Each drawer is heavy because it contains items. If two or more drawers are pulled out, the center of gravity of the drawn drawers will shift outside the chest, causing the chest to tip over towards the side where the drawers were pulled out, resulting in accidents or even personal injury.

[0003] A drawer cabinet anti-tipping mechanism disclosed in CN111166071A includes a fixing strip and a linkage interlocking device installed inside the cabinet. The linkage interlocking device has a stroke of L within the fixing strip. The linkage interlocking device includes multiple sets of sliding rod assemblies that correspond one-to-one with the drawers. The multiple sets of sliding rod assemblies abut against each other in sequence and are interlocked. Each sliding rod assembly includes an upper sliding block and a lower sliding block that are slidably installed on the fixing strip. A rotating block is rotatably provided on the lower sliding block, and the upper part of the rotating block has a curved surface.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-5 As shown, this utility model provides a cabinet drawer interlocking locking mechanism, including an interlocking locking structure 1 and drawers 3. The interlocking locking structure 1 has an elongated outline and is provided with a number of evenly distributed locking plate structures 2 along its length. The drawers 3 are provided with a number of evenly distributed lock plates 2 along the length of the interlocking locking structure 1, and each drawer 3 is provided with a drawer locking hook structure 4. When all drawers 3 are closed, the locking structure 1 is in a released state on all drawer locking hook structures 4. When one drawer 3 is open, the locking structure 1 is in a locked state on the remaining drawer locking hook structures 4.

[0030] See instruction manual attached Figure 3 and Figure 5As shown, the linkage locking structure 1 includes a lock base plate 101 with a U-shaped cross-section. Inner buckle plates 102 are respectively provided on the inner sides of the U-shaped opening of the lock base plate 101. A first inner locking movable plate 103 and a second inner locking movable plate 104 are respectively movably abutted against the inner sides of the two inner buckle plates 102. A lock plate structure 2 is provided between the first inner locking movable plate 103 and the second inner locking movable plate 104 to achieve simultaneous linkage between the two, ensuring the synchronization and stability of the actions during locking and improving the overall linkage control accuracy. The lock base plate 101 and the inner buckle plates 102 are integrally formed and made of aluminum alloy, which reduces the parts assembly process, improves the overall structural integrity and manufacturing precision, and, with its lightweight, high strength, and corrosion resistance, reduces the weight of the mechanism while enhancing structural durability, adapting to long-term, high-frequency use scenarios. An arc-shaped transition is formed at the connection between the lock base plate 101 and the inner buckle plates 102.

[0031] See instruction manual attached Figure 4 As shown, the lock plate structure 2 includes a seat rod 201 mounted on the lock base plate 101. A corner brace 202 is located on one side of the middle portion of the seat rod 201. The lock plate structure 2 also includes an internal lock spring plate 204. One end of the internal lock spring plate 204 is mounted on the lock base plate 101 via the seat plate 205, and the other end of the internal lock spring plate 204 has a V-shaped groove 203 for abutting against the corner brace 202. An opening groove for sliding through the seat rod 201 is provided on the side wall of the lock base plate 101. Two limiting blocks 207 protrude from the seat rod 201 and abut against and limit each other against the inner side wall of the lock base plate 101. During sliding, the limiting blocks 207 always abut against the inner side wall of the lock base plate 101, constraining the lateral displacement of the seat rod 201 and ensuring the straightness of the sliding trajectory. An angle groove 206 is provided on the seat rod 201 for embedding into the side of the first internal lock movable plate 103. In practical applications, the corner groove 206 on the surface of the seat post 201 adopts a groove design that matches the side profile of the first lock inner movable plate 103. The side of the first lock inner movable plate 103 is engaged with the corner groove 206 to form a rigid connection. When the first lock inner movable plate 103 moves, the movement can be accurately transmitted to the seat post 201.

[0032] See instruction manual attached Figure 2 , Figure 3 and Figure 5As shown, the drawer lock hook structure 4 includes a lock hook plate 401. A first lock groove 402 and a second lock groove 403 are respectively formed on the lock hook plate 401. A lock tongue 404 is provided between the first lock groove 402 and the second lock groove 403. An outward push-bevel groove 405 is provided on the side of the lock tongue 404 facing the first lock groove 402, and an inward push-bevel groove 406 is provided on the side of the lock tongue 404 facing the second lock groove 403. An inward locking groove 407 is provided on the side of the inward push-bevel groove 406 facing the second lock groove 403 for limiting and locking in conjunction with the second lock inner movable plate 104. A connecting plate 408 is fixedly connected to the lock hook plate 401, and the connecting plate 408 is fixedly connected to the drawer 3.

[0033] Working principle:

[0034] When all drawers 3 are closed, the linkage locking structure 1 keeps all drawer locking hook structures 4 in a released state, and each drawer can be operated freely; if one of the drawers 3 is opened, the linkage locking structure 1 will trigger the linkage mechanism to lock the drawer locking hook structures 4 of the other drawers, restricting their opening.

[0035] The inner side of the inner snap plate 102 movably abuts against the first lock inner movable plate 103 and the second lock inner movable plate 104, achieving simultaneous linkage between the two through the lock plate structure 2. In the lock plate structure 2, the corner support plate 202 of the seat rod 201 abuts against the V-shaped groove 203 of the lock inner spring plate 204, and cooperates with the limiting block 207 and the corner groove 206 to ensure stable sliding and limiting of the components during linkage.

[0036] When one of the drawers 3 is opened, the latch 404 of its drawer lock hook structure 4 pushes the first lock inner movable plate 103 of the linkage locking structure 1 to rotate under the support of the inner snap plate 102 through the outward push bevel groove 405. At the same time, it pushes the seat rod 201 to move horizontally, and the lock inner spring plate 204 undergoes elastic deformation, achieving elastic support for the seat rod 201 after it moves to a new position. The inner side of the second lock inner movable plate 104 is engaged in the inner snap groove 407, thereby locking the remaining drawers 3. After the opened drawer 3 is closed again, the inward push bevel groove 406 pushes the second lock inner movable plate 104 of the linkage locking structure 1 to rotate under the support of the inner snap plate 102. At the same time, it pushes the seat rod 201 to move horizontally in the opposite direction. The lock inner spring plate 204 undergoes elastic deformation, achieving elastic support for the seat rod 201 after it moves to a new position. The inner side of the second lock inner movable plate 104 separates from the inner snap groove 407. At this time, all drawers 3 can be opened.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
