[0032] The connecting member 4 includes a slider 41, and a slide groove 42 is provided on the outer wall of the cabinet 1. The slider 41 is used in combination with the slide groove 42. The slider 41 is fixedly connected to the partition plate 3. A limiting component 43 is provided between the slider 41 and the slide groove 42. The limiting component 43 is used to fix the position of the partition plate 3. Specifically, the partition plate 3 moves along the track of the slide groove 42 through the slider 41, and when it stops moving, the position of the partition plate 3 is fixed by the limiting component 43.

[0033] The limiting assembly 43 includes a tooth block 431 and a rack 432, wherein the rack 432 is arranged on the inner wall of the slide groove 42, and a rack 433 meshing with the rack 432 is arranged on the outer wall of the tooth block 431, one end of the tooth block 431 extends into a movable groove 434 on the slider 41, and a return spring 435 connected to the tooth block 431 is arranged in the movable groove 434, a magnet block 436 is arranged on the tooth block 431, and an electromagnet 437 is arranged on the inner wall of the movable groove 434. When the electromagnet 437 is energized, the magnet block 436 moves toward the movable groove 434. 34 moves internally; specifically, when it is necessary to change the position of the dividing plate 3, the electromagnet 437 can be energized at this time, the magnet block 436 is attracted to move downward, thereby driving the tooth block 1 431 to move, and then the rack 2 433 can be moved down to the position where the rack 1 432 is separated, and the dividing plate 3 can be moved at this time to adjust the position of the dividing plate 3, thereby changing the distance between the dividing plate 3 and the pushing rod. When the adjustment is completed, the electromagnet 437 is powered off at this time, and under the action of the reset spring 1 435, the rack 2 433 moves upward and resets, and it moves again to the position meshing with the rack 1 432, thereby fixing the position of the dividing plate 3.

[0034] The pushing member 5 includes a push rod 51, which is hinged to the outer wall of the cabinet 1. The length of the push rod 51 is greater than the distance between the partition plate 3 and the push rod 51. Specifically, when the push rod 51 rotates, its end may contact the partition plate 3, thereby generating a thrust on the partition plate 3.

[0035] The pushing member 5 also includes a driving motor 52 and a connecting frame 53. The driving motor 52 is fixedly arranged on the outer wall of the cabinet 1 through the connecting frame 53. The output shaft of the driving motor 52 is connected to the push rod 51. The dividing plate 3 is located within the area covered by the push rod 51 during the rotation process. Specifically, the driving motor 52 is started to make the driving motor 52 drive the push rod 51 to rotate.

The radius of the through hole 63 is larger than the radius of the guide rod 61. Specifically, when the partition plate 3 moves, it moves along the trajectory of the guide rod 61 through the through hole 63, and the radius of the through hole 63 is larger than the radius of the guide rod 61. This is to ensure that when two adjacent cabinets 1 are misaligned, the coordination between the partition plate 3 and the guide rod 61 will not be affected.

[0037] The adjusting member 7 includes a limit block 1 71 and a limit block 2 72, the limit block 1 71 is located in a movable groove 2 opened on the inner wall of the dividing plate 3, and the limit block 2 72 is located in a movable groove 3 opened on the outer wall of the guide rod 61, and the limit block 1 71 and the limit block 2 72 have both an engaged state and a separated state. When the limit block 1 71 and the limit block 2 72 are in an 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 a separated state, the dividing plate 3 moves along the trajectory of the guide rod 61.

[0038] The limit block 71 is triangular in shape, and the limit block 71 is rotatably connected to the movable groove 2 by a hinge shaft. The outer wall of the limit block 71 is provided with a hinged rack three and a rack four 74 on both sides. The rack three and the rack two 433 are meshed with the gear one 75 at the same time, and the rack three and the rack four 74 are both slidably arranged in the movable groove 2; specifically, one end of the triangular limit block 71 is connected to the hinge shaft, and the outer walls of the other two ends thereof are provided with a rack three and a rack four 74. At this time, the inclination angle of the limit block 71 can be adjusted according to the rotation direction of the push rod 51. When the rotation direction of the push rod 51 is to the right, the angle of the limit block 71 needs to be adjusted to be higher on the left and lower on the right, and vice versa, so as to ensure that the unidirectional movement of the limit block 71 can be realized, and a limiting effect is generated on the dividing plate 3 during the movement so that it will not move in the reverse direction;

[0039] The process of adjusting the angle of the limit block 71 is as follows: the gear 75 is mounted on the motor, and after the gear 75 is driven to rotate, the gear 75 will drive the meshing rack 3 73 and the rack 4 74 to move, and the movements of the rack 3 73 and the rack 4 74 are opposite, 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 inclined, 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 a ramp block 77, and the ramp end of the ramp 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 adjustment rod 79 to move, and the adjustment 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 combination, 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 moving 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 arranged 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 to work, 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 away from the cabinet 1 where the accident occurs. At this time, when the partition plate 3 is subjected to a directional force away from the cabinet 1 where the accident occurs, 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 far sides after receiving the thrust, and separate from the cabinet 1 where the accident occurs, to avoid causing more serious losses.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
