[0040] Description of the working process of this embodiment:

[0041] A slot 4 is milled on the surface of the vertical furniture panel, and the locking member 3 is installed therein. The one-way locking edge 3-5 and the front locking edge 3-6 of the locking member 3 respectively lock the locking edge 4-5 and the front locking position 4-6 of the T-shaped slot 4-1, and a locking slot is formed after locking and fixing. When installed, the exit slope 3-4 of the locking member 3 corresponds to the rear end circular hole 4-22 of the slot 4. The first movable lock seat groove 5 is milled on both sides of the corresponding horizontal furniture panel, and the spring 1-11 is clamped on the spring clamping seat 1-10 at the bottom of the lock seat 1-1 to form the first movable lock seat 1, and the spring 1-11 of the first movable lock seat 1 is aligned with the round hole 5-2 of the first movable lock seat groove 5 and inserted, and pressure is applied to the arc top 1-8 of the lock seat 1-1, and the arrow-shaped clamping edge I1-9 enters the composite groove 5-1, and its two wings shrink inward under pressure in the slide 5-3, and after entering the lock seat active cavity 5-4, the pressure is released and it rebounds to reset. The spring 1-11 is clamped on the bottom of the spring cavity 5-6, and the lock seat 1-1 is pushed outward, and the arrow-shaped clamping edge I1-9 is clamped on the clamping top edge 5-5, and the locking head 1-3 protrudes out of the first movable lock seat groove 5. When pressure is applied to the arc top 1-8, the spring 1-11 is compressed, and the positioning sliding body 1-2 slides inward along the slide 5-3, so that the locking head 1-3 is completely buried in the slide 5-3. At the same time, the arrow-shaped card edge I1-9 moves downward in the active cavity 5-4 of the lock seat, pressing the spring 1-11 into the spring cavity 5-6, and rebounds to its original position under the action of the spring 1-11 after the pressure is released.

[0042] Assembling furniture cabinets:

[0043] First, assemble the cabinet frame, and place the locking heads 1-3 protruding from the two side ends of the horizontal top plate and bottom plate of the furniture cabinet into the locking head accommodating cavities 3-3 of the corresponding locking pieces 3 on the left and right vertical furniture panels in turn, and apply force along the direction of the T-shaped locking groove 3-1. The locking body 1-4 of the locking head 1-3 enters the T-shaped locking groove 3-1 along the opening 3-7. At the same time, the introduction slope 1-7 of the locking head 1-5 enters the locking slope 3-2 and gradually increases the locking force. After being in place, the positioning protrusion 1-12 of the lock seat 1-1 fits with the corresponding positioning recess 3-8 of the locking piece 3 to complete the locking positioning. The locking edge 1-6 interacts with the locking edge 3-8 of the locking piece 3 to lock the plate, completing the locking connection between the horizontal plate and the vertical plate. This is performed in sequence to complete the assembly of the cabinet frame.

[0044] The middle vertical board is tilted and placed between the top and bottom boards of the cabinet frame, and then vertically erected. During the verticalizing process, the locking heads 1-3 protruding at the upper and lower ends are gradually squeezed by the top and bottom boards, and the compression spring 1-11 shrinks until it is completely buried in the first movable lock seat groove 5. The middle vertical board is translated to the corresponding locking members 3 on the top and bottom boards. When the locking head 1-3 is facing the locking head accommodating cavity 3-3 of the locking member 3, the locking head 1-3 is released and reset to protrude, enter the locking head accommodating cavity 3-3, and apply force along the direction of the T-shaped locking groove 3-1. After it is in place, the assembly connection of the middle vertical board is completed.

[0045] Tilt the transverse layer sideways, place it into the cabinet frame and then lay it flat. During the process of laying the transverse layer flat, the arc top 1-8 of the locking heads 1-3 protruding from both side ends are gradually squeezed by the left and right vertical plates, and the compression spring 1-11 shrinks inward. After the transverse layer is laid flat, the locking heads 1-3 protruding from both side ends are completely buried in the second movable lock seat groove 5. The transverse layer is translated to the locking members 3 corresponding to the left and right vertical plates. When the locking head 1-3 is facing the locking head accommodating cavity 3-3 of the locking member 3, the locking head 1-3 is released and reset to protrude, enter the locking head accommodating cavity 3-3, and apply force along the direction of the T-shaped locking groove 3-1. After it is in place, the assembly and connection of the transverse layer is completed. This is repeated in sequence to complete the assembly of the entire cabinet.

[0046] If disassembly is required, the transverse plate can be pulled out in parallel. In this process, when the locking head 1-1 exits the T-shaped locking groove 3-1 and reaches the exit slope 3-4 through the locking head accommodating cavity 3-3, it continues to be pulled out in parallel, and the exit slope 3-4 gradually squeezes the arc top 1-8 of the locking head 1-3, so that the lock seat 1-1 gradually compresses the spring and retracts. When the locking head 1-1 is pulled out of the exit slope 3-4, it is completely buried in the first movable lock seat groove 5, and the transverse plate is tilted or continued to be pulled out to complete the disassembly of the transverse plate. The steps are performed in sequence to complete the overall disassembly.
