DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-4A chassis component connection structure includes a fixed block 1 and a plurality of movable blocks 3, the plurality of movable blocks 3 are circumferentially evenly spaced relative to the fixed block 1, a protective cover 2 is provided on the fixed block 1, and a protective pad 4 is provided on the movable block 3, the protective cover 2 is convenient to disassemble and assemble relative to the fixed block 1, and convenient to replace when worn, the protective pad 4 is adhesively connected to the movable block 3, which is convenient to tear off for replacement, and can also be replaced synchronously with the movable block 3, the protective cover 2 is provided on the fixed block 1 and the protective pad 4 is provided on the movable block 3 because: if the force of the equipment installed on the chassis is evenly distributed thereon, then the center position of the chassis will be subjected to a greater force, so the replacement frequency of the protective cover 2 will be greater than that of the protective pad 4, and the movable connection of the protective cover 2 is more convenient for disassembly and assembly.

[0024] An annular cavity 10 and a transmission cavity 11 are provided inside the fixed block 1, a driving motor 12 is provided in the transmission cavity 11, a plurality of screws 13 extending into the transmission cavity 11 are rotatably provided in the annular cavity 10, the screws 13 are connected to the driving motor 12 through a transmission mechanism, a connecting frame 6 is threadedly sleeved on the screw 13, an upper top groove 16 is provided on the connecting frame 6, a positioning block 17 is provided in the upper top groove 16 through an extrusion mechanism, a connecting groove is provided on the movable block 3, and a positioning hole 8 which is connected to the connecting groove and corresponds to the positioning block 17 is provided on the upper end surface of the movable block 3.

[0025] The transmission mechanism includes a driving gear 9 installed on the output shaft of the driving motor 12, and a transmission gear 14 is provided at the end of the screw 13. The transmission gear 14 is meshed with the driving gear 9. The driving gear 9 and the transmission gear 14 are both bevel gears, which are bevel gears and mesh vertically. As shown in the figure, with the cooperation of the above-mentioned gears, the power transmission of the driving motor 12 is realized, and the synchronous rotation of multiple screws 13 can be realized after the driving motor 12 is started, and the thread directions on the multiple screws 13 are set accordingly to ensure that the multiple connecting frames 6 move synchronously close to or away from the driving motor 12.

[0026] The extrusion mechanism includes a spring arranged in the upper top groove 16, and the two ends of the spring are elastically connected to the outer wall of the positioning block 17 and the inner bottom wall of the upper top groove 16 respectively. The spring realizes the upward operation of the positioning block 17 to ensure that when the branch of the connecting frame 6 is in the connecting groove, the positioning block 17 can be pushed up into the positioning hole 8, thereby ensuring the stable connection between the movable block 3 and the connecting frame 6.

[0027] A limiting rod 15 is provided in the annular cavity 10 , and the limiting rod 15 slides through the connecting frame 6 . The limiting rod 15 is used to limit the connecting frame 6 , thereby effectively preventing the connecting frame 6 from rotating together with the screw rod 13 .

[0028] A fixing frame 5 is provided on the movable block 3, a fixing groove is provided on the outer wall of the movable block 3, and a fixing opening 7 is provided on the protective cover 2. When the movable block 3 is in contact and connected with the fixed block 1, the fixing frame 5 can pass through the fixing opening 7 and enter the fixing groove to ensure that the protective cover 2 cannot be vertically separated from the fixed block 1.

[0029] When the utility model is used, the fixed block 1 and the movable block 3 form a chassis. When one of the movable blocks 3 is damaged, it needs to be replaced. At this time, the drive motor 12 is started, and the drive motor 12 drives the active gear 9 to rotate. The active gear 9 cooperates with the transmission gear 14 to drive the screw 13 to rotate. When the screw 13 rotates, the connecting frame 6 threadedly mounted thereon will drive the movable block 3 to move, so that the movable block 3 moves and moves away from the fixed block 1. At this time, the fixed frame 5 is disengaged from the fixing port 7 and the fixing groove. In this state, the protective cover 2 loses its limit and can also be replaced. In this state, the positioning hole 8 is no longer blocked by the protective cover 2. With the help of a long rod-like component, the positioning hole 8 is inserted and the positioning block 17 is pressed down. The positioning block 17 presses down the spring and is disengaged from the positioning hole 8, and the connection between the movable block 3 and the connecting frame 6 is immediately released, and the damaged movable block 3 can be replaced.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
