DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example 1: Please refer to Figure 1 - Figure 5, a metal chassis that is easy to disassemble in this embodiment includes a vertical plate 1 and a fixed block 2, characterized in that a box body 3 is provided on one side of the vertical plate 1, one side of the fixed block 2 is fixedly connected to the inner wall of the box body 3, the fixed block 2 is located on the inner side of the vertical plate 1, the top two ends of the vertical plate 1 are processed with a first movable groove 8, the top two ends of the fixed block 2 are processed with a second movable groove 9, the first movable groove 8 and the second movable groove 9 are connected, a turntable 5 is provided on the outside of the vertical plate 1, the outside of the turntable 5 is fixedly connected with a knob 4, the inner side of the turntable 5 is fixedly connected with a movable shaft 6, and one end of the movable shaft 6 is fixedly connected to a limiting block 7;

[0024] Among them, a rotating groove 12 is processed on one side of the second movable groove 9, the limit block 7 is movably connected inside the rotating groove 12, a first groove 13 is processed on the bottom of the second movable groove 9, a first push plate 15 is movably connected inside the first groove 13, the limit block 7 is located on one side of the first push plate 15, a first return spring 16 is provided on the other side of the first push plate 15, a second groove 14 is processed on the bottom of the first groove 13, a second push plate 17 is movably connected inside the second groove 14, a second return spring 18 is provided on the bottom of the second push plate 17, the bottom of the first push plate 15 is movably connected to the top of the second push plate 17, and the second push plate 17 is located at the bottom of the rotating groove 12;

[0025] When the metal chassis needs to be disassembled, the knob 4 is first pulled outward, and the knob 4 drives the turntable 5 to move outward, and the turntable 5 will drive the movable shaft 6 to move outward, and the movable shaft 6 will drive the limit block 7 to move along the inside of the first groove 13, and at the same time, the limit block 7 will push the first push plate 15 to move along the top of the second push plate 17 and compress the first return spring 16. When the limit block 7 moves to the bottom of the rotating groove 12, the turntable 5 is rotated, and the turntable 5 will drive the limit block 7 to rotate through the movable shaft 6, and the limit block 7 will rotate upward along the inside of the rotating groove 12;

[0026] Secondly, when the stop block 7 reaches the top of the rotating groove 12, the rotating disk 5 is pulled outward, so that the movable shaft 6 is separated from the second movable groove 9 and the first movable groove 8, thereby disconnecting the vertical plate 1 and the fixed block 2. When the rotating disk 5 and the movable shaft 6 on the top of the vertical plate 1 are removed, the vertical plate 1 and the fixed block 2 can be separated;

[0027] At the same time, when the limit block 7 moves to the bottom of the rotation groove 12, the limit block 7 will push the first push plate 15 to disengage from the bottom of the second push plate 17, so that when the limit block 7 rotates upward along the inside of the rotation groove 12, the second push plate 17 will be pushed upward by the elasticity of the second return spring 18, and one end of the second push plate 17 will move upward along one side of the first push plate 15, so that the second push plate 17 restricts the first push plate 15, and prevents the first push plate 15 from blocking the passage of the first groove 13 when the limit block 7 rotates down from the top of the rotation groove 12;

[0028] Further, the other end of the movable shaft 6 is movably connected to the inside of the second movable groove 9, the top of the second movable groove 9 is processed with a second limiting groove 11, and the limiting block 7 is movably connected to the inside of the second limiting groove 11. When the rotating disk 5 drives the movable shaft 6 to move along the inside of the second movable groove 9, the movable shaft 6 will drive the limiting block 7 to move along the inside of the second limiting groove 11.

[0029] Further, one end of the movable shaft 6 is movably connected to the inside of the first movable groove 8, a first limiting groove 10 is processed on the top of the first movable groove 8, and the limiting block 7 is movably connected to the inside of the first limiting groove 10. When the rotating disk 5 drives the movable shaft 6 to move along the inside of the first movable groove 8, the movable shaft 6 will drive the limiting block 7 to move along the inside of the first limiting groove 10.

[0030] Further, one end of the first return spring 16 is fixedly connected to one side of the first push plate 15, the other end of the first return spring 16 is fixedly connected to the inner wall of one end of the first groove 13, one end of the second return spring 18 is fixedly connected to one end of the second push plate 17, and the other end of the second return spring 18 is fixedly connected to the bottom inner wall of the second groove 14;

[0031] When the vertical plate 1 and the fixed block 2 need to be assembled and connected together, the movable shaft 6 is inserted into the first movable groove 8 and the second movable groove 9, and then the turntable 5 is rotated so that the limit block 7 moves downward along the inside of the rotating groove 12. When the limit block 7 reaches the bottom of the rotating groove 12, the limit block 7 will push the second push plate 17 to move downward, so that the second push plate 17 enters the inside of the second groove 14, so that the first push plate 15 can move along the top of the second push plate 17, and the first push plate 15 will be pushed to move by the elasticity of the first return spring 16, and the first push plate 15 will push the limit block 7 to move, so that the elasticity of the first return spring 16 can push the first push plate 15 to squeeze the limit block 7, thereby limiting the movement of the limit block 7;

[0032] Furthermore, a first clamping block 19 is fixedly connected to one side of the first push plate 15, a first clamping groove 20 is processed on one side of the first groove 13, and the first clamping block 19 is movably connected to the inside of the first clamping groove 20. When the first push plate 15 moves, the first push plate 15 will drive the first clamping block 19 to move, and the first clamping block 19 will move along the inside of the first clamping groove 20. By setting the first clamping groove 20, the movement of the first push plate 15 can be limited, so that the first push plate 15 can maintain a stable state when moving;

[0033] Furthermore, a second clamping block 21 is fixedly connected to one side of the second push plate 17, a second clamping groove 22 is processed on one side of the first groove 13, and the second clamping block 21 is movably connected to the inside of the second clamping groove 22. When the second push plate 17 moves, the second push plate 17 will drive the second clamping block 21 to move, and the second clamping block 21 will move along the inside of the second clamping groove 22. By setting the second clamping groove 22, the movement of the second push plate 17 can be limited, so that the second push plate 17 can maintain a stable state when moving.

[0034] Working principle: first pull the knob 4 outward to make the turntable 5 drive the movable shaft 6 to move outward, and the movable shaft 6 will drive the limit block 7 to move along the inside of the first groove 13. At the same time, the limit block 7 will push the first push plate 15 to move along the top of the second push plate 17. When the limit block 7 moves to the bottom of the rotating groove 12, turn the turntable 5, and the movable shaft 6 will drive the limit block 7 to rotate upward along the inside of the rotating groove 12. When the limit block 7 reaches the top of the rotating groove 12, pull the turntable 5 outward, so that the movable shaft 6 is disengaged from the inside of the second movable groove 9 and the first movable groove 8, so that the vertical plate 1 and the fixed block 2 are disconnected, thereby separating the vertical plate 1 and the box body 3, which is convenient for disassembly of the metal chassis.
