For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific situations.

[0024] As Figures 1 to 2 shown, the embodiments of the present utility model provide a guiding device, including a first guide wheel 100, a second guide wheel 200, a mounting bracket 300, a guide rail 400, and a third guide wheel 500. It should be understood that the mounting bracket 300 is fixedly connected to the car.

[0025] Furthermore, the first guide wheel 100 and the second guide wheel 200 are spaced apart on the mounting bracket 300, and their axes are parallel. The guide rail 400 includes a first side wall 410. The first side wall 410 passes through between the first guide wheel 100 and the second guide wheel 200 and is movably connected to the first guide wheel 100 and the second guide wheel 200. That is, by setting the second guide wheel 200 to cooperate with the first guide wheel 100, when the car vibrates, the problem of the first guide wheel 100 jumping can be avoided, the car can move up and down more smoothly, the work efficiency can be improved, and the comfort in use and the service life of the guiding device can be improved.

[0026] In an embodiment, the third guide wheel 500 is disposed on the mounting bracket 300, and its axis is perpendicular to that of the first guide wheel 100. The guide rail 400 includes a vertical wall 420 which is vertically disposed in the middle of the side of the first side wall 410 away from the second guide wheel 200. Two first guide wheels 100 and two third guide wheels 500 are symmetrically disposed with respect to the vertical wall 420 to ensure the stability of the guiding device. The third guide wheel 500 is movably connected to the vertical wall 420 to prevent the car from swaying left and right.

[0027] In an embodiment, the mounting bracket 300 includes a body 310 and connecting arms 320. Among them, the body 310 is disposed on the side of the first side wall 410 away from the vertical wall 420. A gap for accommodating the second guide wheel 200 is formed between the body 310 and the first side wall 410. The connecting arms 320 are disposed at both ends of the body 310 and extend along the direction in which the body 310 is away from the vertical wall 420. The first guide wheel 100 and the second guide wheel 200 are disposed on the connecting arms 320. The third guide wheel 500 is connected to the two connecting arms 320, that is, both ends of the rotating shaft of the third guide wheel 500 are fixedly connected to the corresponding connecting arms 320. The overall structure of the mounting bracket 300 is simple, facilitating production and processing, as well as subsequent disassembly, assembly and maintenance.

[0028] In an embodiment, a connecting shaft 110 extending away from the vertical wall 420 is disposed on the first guide wheel 100. A bayonet 321 is disposed on the connecting arm 320. The connecting shaft 110 is snap-fitted with the bayonet 321. A threaded layer (not shown in the figure) is disposed at the extending end of the connecting shaft 110. Two nuts 120 are connected to the threaded layer. The two nuts 120 are respectively disposed on both sides of the connecting arm 320 and can be in close contact with the connecting arm 320. Specifically, one of the nuts 120 is a right-handed nut and the other nut 120 is a left-handed nut. More specifically, the nut 120 close to the third guide wheel 500 is a left-handed nut. That is, by tightening the two nuts 120, the connecting shaft 110 can be locked, which is convenient for disassembly and assembly and facilitates maintenance and replacement.

[0029] It should be understood that the cross-section of the first guide wheel 100 is conical. A slope (not shown in the figure) matching the outer side surface of the first guide wheel 100 is disposed on the surface of the first side wall 410 away from the second guide wheel 200. By adjusting the two nuts 120, the distance between the third guide wheel 500 and the vertical wall 420 can be adjusted so that the first guide wheel 100 cooperates with the slope to improve the stability of the guiding device.

[0030] In one embodiment, a second side wall 430 is provided at one end of the vertical wall 420 away from the first side wall 410. It should be noted that the second side wall 430 is connected to an object, and the shape of the second side wall 430 is the same as that of the first side wall 410. Specifically, the mounting bracket 300 is in an I shape.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
