[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0014] See Figures 1 to 2As shown, a snap-fit ​​connection structure for furniture includes a first board 1 and a second board 2. The first board has a snap-fit ​​cavity 3, and the inner wall of the snap-fit ​​cavity has a snap-fit ​​annular groove 4. A snap-fit ​​boss 5 is fixed to the bottom wall of the snap-fit ​​cavity. A snap-fit ​​ring 6 is disposed within the snap-fit ​​annular groove, and a spring 12 is disposed between the bottom of the snap-fit ​​ring 6 and the bottom wall of the snap-fit ​​annular groove. In this embodiment, the height of the snap-fit ​​boss is 2-5 cm. The snap-fit ​​ring 6 is a metal structural component. The thickness of its snap-fit ​​ring matches the width of the snap-fit ​​annular groove. The snap-fit ​​annular groove refers to a communicating groove formed on the inner wall of the snap-fit ​​cavity. In this embodiment, the snap-fit ​​cavity is rectangular, therefore the snap-fit ​​annular groove is also rectangular. The side grooves of the snap-fit ​​annular groove are used for guidance, while the top and bottom grooves are used for lifting and lowering movement.

[0015] During assembly, under the action of the spring, the bottom edge and top surface of the locking ring are flush with the top surface of the buckling boss; and a buckling protrusion 7 with a shape matching the shape of the locking cavity is fixed on the second plate. The bottom surface of the buckling protrusion is provided with a buckling groove 8, and the top surface of the buckling protrusion is provided with a limiting groove 9. During assembly, the buckling protrusion is inserted into the locking cavity, and under the action of gravity, the buckling protrusion engages with the buckling groove. The bottom surface of the buckling protrusion presses downward against the locking ring, and the top wall of the locking ring engages with the limiting groove for limitation. The inner cavity height of the locking ring is the same as the distance between the top surface of the buckling boss and the top wall of the locking cavity. Once the buckle protrusion is inserted into place, under the action of gravity, the buckle groove will lock onto the buckle protrusion. This will cause the locking ring to move downward and lock into the limiting groove for limiting, which can prevent the buckle protrusion from loosening or falling off, ensuring the stability and reliability of the connection, and also facilitating disassembly and maintenance.

[0016] In this embodiment, a ring mounting area 10 is provided on the side of the first plate. The ring mounting area is located at the top of the locking recess, and the top of the locking ring groove is connected to the ring mounting area. A cover 11 is fixed to the ring mounting area with screws. During installation, the locking ring is inserted into the locking groove from the ring mounting area and closed by the cover to ensure the overall aesthetic appearance.

[0017] Furthermore, the depth of the ring mounting area is 1 / 2 to 1 / 3 of the depth of the locking cavity. The height of the snap-fit ​​boss is 2-5 cm.

[0018] This utility model has positive effects: The structure of this utility model is reasonably designed. It uses a locking cavity with a locking protrusion and a locking boss with a locking ring. During assembly, the locking protrusion is inserted into the locking cavity, and the locking protrusion and locking groove are used for positioning. At the same time, the locking ring is locked into the limiting groove, which can prevent loosening or falling off, improve the stability and reliability of assembly, and also help to improve the convenience and effectiveness of disassembly and maintenance. It can be disassembled and moved as needed, and has strong applicability.

[0019] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0020] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
