[0025] Embodiment 1:

[0026] The quick docking structure of the mobile chassis provided by the utility model is preferably implemented as follows: Figures 1 to 6 As shown: a quick docking structure of a mobile chassis, comprising a device body 1 and a mobile chassis 3, a fixed chassis 2 is fixedly installed at the bottom end of the device body 1, a docking mechanism 5 is arranged between the mobile chassis 3 and the fixed chassis 2, and a universal wheel 4 is fixedly installed at the bottom end of the mobile chassis 3;

[0027] The docking mechanism 5 includes a contraction groove 501 and a pin 507. The contraction groove 501 is provided on one side of the mobile chassis 3, and a stopper 502 is inserted in the contraction groove 501. An L-shaped fixing plate 503 is fixedly installed on one side of the fixed chassis 2, and a contact switch 504 is fixedly installed on the inner side of the L-shaped fixing plate 503. One end of the stopper 502 contacts the contact switch 504. A contraction groove 505 is provided at the bottom end of the mobile chassis 3, and a pin 507 is inserted in the contraction groove 505. A spring 506 is fixedly connected between the bottom end of the pin 507 and the bottom end of the inner wall of the contraction groove 505. A pin groove 508 is provided at the bottom end of the fixed chassis 2, and the pin 507 is inserted in the pin groove 508. An electromagnet 509 is fixedly installed on the top of the inner wall of the pin groove 508. The electromagnet 509 is magnetically connected to the pin 507, and the contact switch 504 is electrically connected to the electromagnet 509.

[0028] Specifically, in the above technical scheme, when it is necessary to install and dock the mobile chassis 3, the electric push rod 11 is started, and the electric push rod 11 drives the fixed chassis 2 to move upward, so that a certain gap is formed between the fixed chassis 2 and the ground, and then the mobile chassis 3 is pushed to the bottom of the fixed chassis 2, so that the limit card strip 6 is inserted into the limit card slot 7. When the mobile chassis 3 drives the stop block 502 to contact the contact switch 504, the electromagnet 509 is energized. At this time, the pin 507 will move upward under the attraction of the electromagnet 509, so that the pin 507 is inserted into the pin slot 508, and finally the pin 507 is in contact with the electromagnet 509 to complete the installation of the mobile chassis 3. Through this mechanism, it is convenient for personnel to quickly install and dock the mobile chassis 3, thereby ensuring the working efficiency of the equipment body 1, and solving the problem that the existing mobile chassis 3 is mostly fixed by positioning bolts during installation and docking, which requires personnel to carry specific wrench tools, has certain operating limitations, and docking is relatively slow, thereby affecting the working efficiency of the equipment.

[0029] Furthermore, the material of the pin 507 is iron, the number of the second contraction groove 505, the pin 507 and the pin groove 508 are all four, and the pin 507 is matched with the second contraction groove 505 and the pin groove 508;

[0030] Among them, by providing the pin 507, the pin 507 can be inserted into the pin groove 508, so that the movable chassis 3 can be limited.

[0031] Furthermore, an electric push rod 11 is fixedly installed at the bottom end of the fixed chassis 2, the number of the electric push rod 11 is four, and a support block 12 is fixedly installed at the output end of the four electric push rods 11;

[0032] Wherein, by providing the electric push rod 11, the height between the fixed chassis 2 and the ground can be adjusted.

[0033] Embodiment 2:

[0035] Specifically, in the above technical scheme, when it is necessary to disassemble the mobile chassis 3, the pull ring 10 can be pulled, and the pull ring 10 drives the stop block 502 to shrink into the shrinkage groove 1 501 through the connecting rope 8, and the stop block 502 compresses the spring 1 9, so that the stop block 502 does not contact the contact switch 504. At this time, the electromagnet 509 is powered off, and the pin 507 will shrink to the shrinkage groove 2 505 under the reset force of the spring 1 9, so that the pin 507 no longer limits the mobile chassis 3. At this time, the mobile chassis 3 will move in the direction of the pull ring 10 under the reset force of the spring, and detach from the fixed chassis 2 to complete the disassembly, which is convenient for personnel to disassemble the mobile chassis 3 and improves the work efficiency of the personnel. In addition, by setting the limit card strip 6 and the limit card slot 7, the mobile chassis 3 can be limited to ensure the accuracy of the position of the mobile chassis 3 during installation.
