Further, the inner side surface of the accommodating groove is provided with an expansion layer.
Furthermore, the diameter of the accommodating groove is gradually narrowed inwards, and the outline of the limiting block is correspondingly matched with the accommodating groove.
Furthermore, the buffer device also comprises a buffer spring, and the buffer spring is sleeved on the pin shaft.
Furthermore, a first magnet layer is arranged at the center of the inner side surface of the rolling wheel body, a second magnet layer is arranged at the center of the brake wheel body, and the magnetism of the first magnet layer is different from that of the second magnet layer.
Furthermore, a plurality of elastic salient points are arranged on the outer surface of the pin shaft.
Furthermore, the elastic salient points are annularly arranged on the outer surface of the pin shaft.
Further, the elastic bumps are made of rubber.
According to the stable roller for the shopping cart in the market, the arrangement of the elastic buffer sheet and the limiting block is utilized, so that the rolling wheel body is pressed towards the middle part of the pin shaft, the left-right swinging in the rolling process is avoided, and meanwhile, the elastic buffer sheet can also play a role in correcting the swinging of the rolling wheel body.
For a better understanding and practice, the invention is described in detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic of the present invention.
Detailed Description
The invention discloses a stable roller for a shopping cart in a shopping mall, which comprises a base 10, a brake wheel body 20 and a rolling wheel body 30; two convex pieces 11 are convexly arranged on one side of the base 10, the brake wheel body 20 is arranged between the two convex pieces 11, the rolling wheel body 30 is arranged between the convex pieces 11 and the brake wheel body 20, and a pin shaft 12 penetrates through the convex pieces 11, the rolling wheel body 30 and the brake wheel body 20; the bottom of the brake wheel body 20 is provided with a brake block 21, and the bottom of the brake block 21 is provided with a high friction coefficient layer; the rolling wheel body 30 is provided with a containing groove 31 for containing the limiting block 42 and the elastic buffering sheet 41, and the elastic buffering sheet 41 is arranged between the rolling wheel body 30 and the limiting block 42. After the assembly is completed, the end of the pin 12 presses the stopper 42 into the receiving groove 31 of the rolling wheel 30.
The inner side surface of the accommodating groove 31 is provided with the expansion layer 32, so that the pretightening force between the limiting block 42 and the rolling wheel body 30 can be increased. The diameter of the receiving groove 31 is gradually narrowed inward, and the contour of the stopper 42 is correspondingly matched with the receiving groove 31, so that the stopper 42 can be more stably placed in the rolling wheel body 30.
The buffer device further comprises a buffer spring 51, and the buffer spring 51 is sleeved on the pin shaft 12. A first magnet layer 53 is arranged at the center of the inner side surface of the rolling wheel body 30, a second magnet layer 54 is arranged at the center of the brake wheel body 20, and the first magnet layer 53 and the second magnet layer 54 have different magnetism. A plurality of elastic salient points 52 are arranged on the outer surface of the pin shaft 12. The elastic salient points 52 are annularly arranged on the outer surface of the pin shaft 12. The elastic bumps 52 are made of rubber. The rolling wheel body 30 is moved toward the brake wheel body 20 by the elastic force of the buffer spring 51. The first magnet layer 53 and the second magnet layer 54 have different magnetism, and when the rolling wheel body 30 and the brake wheel body 20 are assembled, the first magnet layer 53 and the second magnet layer 54 are tightly attached to each other, so that the rolling wheel body 30 can be stably attracted back by magnetic force even if the rolling wheel body 30 shakes outward. The elastic salient points 52 can play a limiting role and are clamped outside the rolling wheel body 30 to prevent the rolling wheel body from shaking outwards.
According to the stable roller for the shopping cart in the market, the arrangement of the elastic buffer sheet and the limiting block is utilized, so that the rolling wheel body is pressed towards the middle part of the pin shaft, the left-right swinging in the rolling process is avoided, and meanwhile, the elastic buffer sheet can also play a role in correcting the swinging of the rolling wheel body.
The present invention is not limited to the above-described embodiments, and various modifications and variations of the present invention are intended to be included within the scope of the claims and the equivalent technology of the present invention if they do not depart from the spirit and scope of the present invention.
