The limit block 1 71 and the limit block 2 72 have both engaged and disengaged states. When the limit block 1 71 and the limit block 2 72 are in the engaged state, the dividing plate 3 and the guide rod 61 are relatively fixed; when the limit block 1 71 and the limit block 2 72 are in the disengaged state, the dividing plate 3 moves along the trajectory of the guide rod 61.

[0038] When the lever 51 is in the unlocked position, the gear 73 is locked and the pinion 73 is locked, so the pinion 73 is locked. When the lever 51 is unlocked, the gear 73 is locked and the pinion 73 is locked. When the lever 51 is unlocked, the gear 73 is locked and the pinion 73 is locked.

[0039] The process of adjusting the angle of the limit block 71 is as follows: gear 1 75 is mounted on the motor. After driving gear 1 75 to rotate, gear 1 75 will drive the meshing rack 3 73 and rack 4 74 to move, and the movements of rack 3 73 and rack 4 74 are in opposite directions, thereby achieving the purpose of adjusting the angle of the limit block 71.

[0040] The limit block 2 72 is triangular, and the limit block 2 72 is hinged in the movable groove 3. When the limit block 2 72 and the limit block 1 71 are both horizontal, the limit block 2 72 is separated from the limit block 1 71; when the limit block 2 72 and the limit block 1 71 are tilted, the limit block 1 71 is engaged with the limit block 2 72, and the outer wall of the limit block 2 72 is provided with a hinged connecting rod 1 76, and one end of the connecting rod 1 76 is provided with an inclined block 77, and the inclined end of the inclined block 77 is provided with a sliding connection connecting rod 2 78, and the connecting rod 2 78 is connected to the adjusting rod 79, and the adjusting rod 79 is connected to the electric telescopic rod 710; specifically, one end of the limit block 2 72 is hinged to the inside of the movable groove 3 through a hinge shaft. When When the angle of limit block 1 71 is adjusted, the angle of limit block 2 72 needs to be adjusted synchronously so that the end face of limit block 2 72 is parallel to the end face of limit block 1 71. The process of adjusting the angle of limit block 2 72 is as follows: start the electric telescopic rod 710, and the shortening of the electric telescopic rod 710 will drive the adjusting rod 79 to move, and the adjusting rod 79 will drive the connecting rod 2 78 to move, and the top end face of the connecting rod 2 78 will move on the surface of the inclined block 77. Since a guide block is provided at the top of the connecting rod 2 78 and a guide groove is provided on the inclined end of the inclined block 77, the guide block and the guide groove are used in conjunction with each other, so that when the connecting rod 2 78 moves horizontally, it will drive the connecting rod 1 76 to move vertically, and the connecting rod 1 76 will drive one end of the limit block 2 72 to move, thereby causing the limit block 2 72 to tilt.

[0041] The movable part 2 includes a universal wheel 21 and a cylinder 22. The universal wheel 21 is installed at the bottom of the cabinet 1, and the universal wheel 21 is provided at the telescopic end of the cylinder 22. Specifically, when the cabinet 1 needs to be moved, the cylinder 22 can be started to drive the universal wheel 21 to move, and the universal wheel 21 is moved to contact the ground, and the cabinet 1 is separated from the ground. At this time, the cabinet 1 can be conveniently pushed to move.

[0042] Working principle: When an accident occurs inside a cabinet 1, the other cabinets 1 on both sides of the cabinet 1 can be separated to prevent the problem inside the cabinet from affecting the normal operation of other cabinets 1. The separation process is: start the drive motor 52 and the cylinder 22 on the adjacent cabinet 1, so that the universal wheel 21 on the adjacent cabinet 1 starts working, and at the same time, the rotation of the drive motor 52 will drive the push rod 51 to rotate, and the end of the push rod 51 will contact the partition plate 3 during the rotation process and generate thrust on the partition plate 3. At this time, the rotation direction of the push rod 51 is to rotate toward the side of the cabinet 1 away from the accident. At this time, when the partition plate 3 is subjected to a directional force away from the cabinet 1 where the accident occurred, since the state between the partition plate 3 and the cabinet 1 is adjusted to a fixed state, the partition plate 3 will drive the adjacent cabinets 1 to move to the two sides away from the accident after being thrust, and separate from the cabinet 1 where the accident occurred, to avoid causing more serious losses.

[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
