[0043] Description of the working process of this embodiment:

[0044] A slot 7 is milled on the surface of a vertical furniture panel, and the locking member 6 is inserted into the slot. The one-way locking edge 6-5 and the front one-way locking edge 6-6 of the locking member 6 are locked in the T-shaped slot 7-1 and the front slot 7-2 of the locking member slot 7 to form a first locking slot. When installed, the lock seat accommodating cavity 6-4 of the locking member 6 corresponds to the circular hole 7-3 of the locking member slot 7. Movable lock seat grooves 3 are milled on both sides of the corresponding horizontal furniture panel, and the spring 1-10 is clamped on the spring seat 1-9 of the lock seat 1-1, and then the lower end of the spring 1-10 is clamped on the spring base 2-6 of the first clamping sleeve 2. The I-shaped load-bearing body 1-2 of the lock seat 1-1 enters the first clamping sleeve 2 along the slide 2-2, and its clamping edge 1-8 is clamped on the upper clamping surface 2-1 of the first clamping sleeve 2 by the spring top. The locking edge 1-3, locking slope 1-4, anti-reverse installation end face 1-5, disassembly arc surface 1-6, arc surface top 1-7 and part of the I-shaped load-bearing body 1-2 of the lock seat 1-1 protrude from the supporting top 2-4 of the first clamping sleeve 2 to form the first movable lock seat 1 as a whole.

[0045] Insert the first movable lock seat 1 into the first movable lock seat groove 3, and the side locking card 2-8 and the rear locking card 2-9 of the first clamping sleeve 2 are locked in the linear clamping slot 3-1 and the rear clamping slot 3-2 of the movable lock seat groove 3; the round hole 3-3 of the movable lock seat groove 3 corresponds to the lock seat dumping cavity 2-10 of the movable lock seat 1, and after the movable lock seat 1 is clamped in the movable lock seat groove 3, its supporting top 2-4 is flush with the side end of the plate; applying force on the arc surface top 1-7 of the movable lock seat 1 can make the lock seat 1-1 retract along the slideway 2-2 of the clamping sleeve 2, and compress the spring 1-10 in the lock seat movable cavity 2-5 to its arc surface top 1-7 It is completely buried in the first ferrule 2 and can pop out when pressure is released; apply force forward at the rear upper end of the movable lock seat 1, and the positioning load-bearing body 1-2 of the lock seat 1-1 will tilt forward along the slide 2-2 and the front opening 2-7 of the first ferrule 2, and its locking edge 1-3 will tilt forward along the tilting arc 2-11, and its clamping edge 1-8 will move and tilt along the upper clamping surface 2-1 and the front clamping surface 2-3, until the lock seat 1-1 is completely buried in the lock seat tilting cavity 2-10, and the lock seat 1-1 does not protrude from the supporting top 2-4 of the first ferrule 2, and can bounce back when pressure is released, and the upper clamping surface 2-1 and the front clamping surface 2-3 prevent the lock seat 1-1 from escaping from the first ferrule 2.

[0046] First, assemble the cabinet frame, place the lock seat 1-1 protruding from both sides of the horizontal plate into the lock seat introduction cavity 6-4 of the first locking groove of the corresponding vertical plate, apply force along the direction of the T-shaped locking groove 6-1 of the locking member 6, and the I-shaped load-bearing body 1-2 of the lock seat 1-1 enters the opening 6-3. At the same time, the locking slope 1-4 of the lock seat 1-1 enters the introduction slope 6-2 of the first locking groove. The two interact with each other to gradually increase the locking force. After they are in place, the locking edge 1-3 of the lock seat 1-1 is locked in the T-shaped locking groove 6-1 of the locking member 6, completing the assembly connection of the plates. Repeat this process in sequence to complete the cabinet frame assembly connection.

[0047] Then install the shelf, first place the lock seat 1-1 protruding from one side end of the plate into the lock seat introduction cavity 6-4 of the first locking groove of the corresponding vertical plate, and then push or press the other side end of the plate in the horizontal direction so that the lock seat 1-1 protruding from the side end of the plate is gradually aligned with the lock seat introduction cavity 6-4 of the corresponding vertical plate. In this process, the vertical plate gradually squeezes the arc top 1-7 of the lock seat 1-1 to make it gradually shrink inward. When the arc top 1-7 of the lock seat 1-1 is facing the lock seat introduction cavity 6-4, the lock seat 1-1 is released and pops out, enters the lock seat introduction cavity 6-4, and applies force in the direction of the T-shaped locking groove 6-1. After it is in place, the plate locking connection is completed. This is carried out in sequence to complete the assembly and connection of the entire cabinet. If disassembly is required, apply force in the horizontal direction, the lock seat 1-1 will withdraw from the T-shaped locking slot 6-1 and retreat to the lock seat introduction slot 6-4, and continue to apply force. The end wall of the lock seat introduction slot 6-4 will press against the disassembly arc surface 1-6 at the upper rear end of the lock seat 1-1, so that the lock seat 1-1 will tilt forward and gradually be completely buried in the lock seat inclined cavity 2-10. The upper clamping surface 2-1 and the front clamping surface 2-3 of the first clamping sleeve 2 will clamp the clamping edge 1-8 of the lock seat 1-1, so that the lock seat 1-1 will only tilt forward without falling out, and the panel will be directly pulled out to complete the panel disassembly. This will be carried out in sequence to complete the disassembly of the entire cabinet.

[0048] During the assembly process, if it is accidentally installed upside down (turned front to back), the anti-reverse installation end face 1-5 of the lock seat 1-1 will press against the end of the T-shaped locking slot 6-1, so that the lock seat 1-1 cannot enter the T-shaped locking slot 6-1. Continue to apply force, the lock seat 1-1 will tilt and gradually be completely buried in the sleeve 2, and force can be applied upward or downward to remove the plate and reinstall it.
