Description

Technical Field

[0001] This utility model relates to drawers, specifically to a drawer door panel connecting mechanism and a drawer. Background Technology

[0002] Existing drawers generally consist of a front panel, a back panel, a bottom panel, and two side panels. The side panels are connected to the front panel via a detachable mechanism, as shown in Figures 11-12 of the specification of utility model patent CN221635337U. As can be seen from the figures, a disassembly mechanism is provided between the drawer front panel and the side panels. This mechanism includes a movable locking piece that rotates elastically on a positioning element. The drawer front panel has a connecting piece that cooperates with the movable locking piece. When the movable locking piece is in a ready state, the connecting piece of the front panel is inserted into the disassembly mechanism. When the movable locking plate rotates to the corresponding position angle, the connecting piece locks with the movable locking plate. Since there is a movement space 26 at the engagement point between the movable locking plate and the connecting piece, and there is only one locking point between the movable locking plate and the positioning piece, and since the movable locking plate rotates elastically, there is a pull-out gap between the panel and the side panel when the user pulls out the panel, causing the panel to wobble when the user pulls out the panel. This is especially true when installing drawer panels with a larger installation height, as the fulcrum for pulling out the panel increases, thus increasing the pull-out gap between the panel and the side panel. Further improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems and provide a drawer door panel connecting mechanism. When the user pulls out the panel, the panel is not easy to shake. When the panel is installed at a high height, it can effectively reduce the gap between the panel and the side panel when pulling out.

[0004] Another objective of this invention is to provide a drawer.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A drawer door panel connecting mechanism includes a side panel connector, a middle connector, a locking assembly, and a panel connecting assembly;

[0007] The side plate connector is fixedly connected inside the side plate;

[0016] When it is necessary to fix the panel and the side plate, the panel connecting assembly is first fixed to the panel, and then one end of the panel connecting assembly is inserted into the connecting channel, so that the locking rod of the panel connecting assembly approaches and enters the locking groove of the locking piece, and then the locking piece is pushed to rotate in the corresponding direction; when the connecting point of the locking elastic piece and the locking piece moves to above the horizontal plane where the rotation center of the locking piece is located, the locking elastic piece releases potential energy to continue driving the locking piece to rotate, the unlocking piece is synchronously rotated, until the panel and the side plate are attached, and the unlocking piece is limited by the locking limiting structure, so that the panel is prevented from being loosened.

[0017] When it is necessary to separate the panel and the side plate, the locking of the unlocking piece by the locking limiting structure is contacted first, and then the unlocking piece is rotated in the opposite direction, so that the locking piece is driven to rotate by the unlocking piece, the orientation of the slot opening of the locking groove is changed, until the locking rod can come out of the locking groove, at this time, the locking assembly is changed to the unlocked state, and then the panel and the side plate can be separated.

[0018] In one preferred embodiment of the present application, the locking assembly further comprises an unlocking screw, which is fixedly connected with the unlocking member, and the side plate is provided with an unlocking operation hole.

[0019] In one preferred embodiment of the present application, the unlocking member is provided with an unlocking limiting boss for abutting against the intermediate connecting member.

Through the above structure, when the panel needs to be separated from the side plate, the other end of the anti-falling limiting member is first lifted to be away from the anti-falling limiting boss, so that the limiting is released, and the unlocking member is operated for unlocking operation.

[0021] Further, the other end of the anti-falling limiting member is provided with a limiting release operation part extending to the side close to the unlocking operation hole of the unlocking screw. In this way, during unlocking, the other end of the anti-falling limiting member is lifted by a screwdriver, and then the unlocking screw is rotated, so that the unlocking operation is performed.

[0022] In one preferred embodiment of the present application, the locking elastic member is a torsion spring, one end of the torsion spring is connected with the locking member, and the other end of the torsion spring is connected with the side plate connecting member.

[0023] A drawer comprises the drawer door panel connecting mechanism.

[0024] Compared with the prior art, the present application has the following beneficial effects:

[0025] The connecting mechanism has high stability, the panel is not easy to shake when the user pulls the panel, and when a panel with high installation height is installed, the interval between the panel and the side plate during pulling can be effectively reduced. BRIEF DESCRIPTION OF DRAWINGS
