Detailed Description
An embodiment of the stroller according to the present utility model is described in further detail with reference to fig. 1 to 5.
A stroller comprising a frame 1 and a wheel assembly 2, the wheel assembly 2 comprising a wheel axle 22 and wheels 21 rotatably disposed on the wheel axle 22; the outside of the wheel 21 is provided with a friction pad 214, one end part of the wheel shaft 22 is detachably arranged on the frame 1, the other end part of the wheel shaft passes through the wheel 21 and is provided with a pressing component 23 which can press the friction pad 214 towards the wheel 21, and the pressing component 23 comprises a pressing cover 231, an adjusting cover 232 and a pressing spring arranged between the pressing cover 231 and the adjusting cover 232;
The end part of the wheel shaft 22 is provided with a positioning block 221 in an outward protruding way, the adjusting cover 232 can axially move relative to the pressing cover 231, and a shallow groove 2311 and a deep groove 2312 which are matched with the positioning block 221 are formed on one side of the pressing cover 231 facing the wheel shaft 22 at intervals; the adjusting cover 232 drives the pressing cover 231 to rotate, so that the deep groove 2312 of the pressing cover 231 corresponds to the positioning block 221, and the pressing spring drives the pressing cover 231 to move towards one end of the wheel axle 22 and press the friction pad 214 inwards;
When the stroller is used for pushing a child, the adjusting cover 232 is only required to be rotated, and the adjusting cover 232 drives the pressing cover 231 to rotate together to a position where the deep groove 2312 corresponds to the positioning block 221 on the wheel shaft 22; the pressing spring between the adjusting cover 232 and the pressing cover 231 drives the pressing cover 231 to move inwards, at this time, the gap between the end surface of the pressing cover 231 and the wheel 21 is smaller than the thickness of the friction pad 214, the pressing cover 231 presses the friction pad 214 inwards, and a plurality of anti-slip protrusions are distributed on the surface of the pressing cover 231 and cling to the surface of the friction pad 214; the friction pad 214 is tightly attached to the wheel 21, and when a child pushes the cart, the friction pad 214 is continuously rubbed with the wheel 21, so that the wheel 21 has larger resistance in the rolling process, and the cart can slowly and safely slide, and the safety of the child can be effectively ensured; when the device is used for adult pushing, only the adjusting cover 232 is required to be rotated, so that the shallow groove 2311 of the pressing cover 231 is opposite to the positioning block 221 on the wheel shaft 22, the positioning block 221 can jack up the pressing cover 231 outwards, at this time, the gap between the end surface of the pressing cover 231 and the wheel 21 is larger than the thickness of the friction pad 214, the pressing cover 231 is separated from the friction pad 214, and the pressing spring is compressed; a certain gap exists between the friction pad 214 and the wheel 21, and the wheel 21 cannot contact with the friction pad 214 in the rolling process, so that the wheel 21 can smoothly slide forwards without resistance;
The pressing assembly 23 is built in the front cover plate 212 of the wheel 21, the built-in cavity of the front cover plate 212 is matched with the shape of the adjusting cover 232, and the outer edge of the adjusting cover 232 can limit the swing amplitude of the wheel; to prevent the wheel 21 from swinging too much, resulting in the wheel 21 contacting the friction pad 214 with the anti-slip protrusions of the pressing cover 231 surface in the unlocked state, which affects the normal rolling of the wheel 21.
Wherein a pair of positioning blocks 221 are oppositely arranged at the end of the wheel shaft 22, a pair of shallow grooves 2311 and a pair of deep grooves 2312 are oppositely arranged on the pressing cover 231, and the pair of shallow grooves 2311 and the pair of deep grooves 2312 are mutually perpendicular; after the adjustment cover 232 is rotated by 90 degrees each time, the adjustment of the non-resistance and resistance states of the wheels 21 can be realized, and the purpose of accurate adjustment is achieved.
The pressing cover 231 is provided with a plurality of sleeving holes 2313 at intervals, sleeving columns 2321 matched with the sleeving holes 2313 are arranged at intervals on one side, facing the pressing cover 231, of the adjusting cover 232, the pressing cover 231 is mounted on the adjusting cover 232 in a matched mode through the sleeving holes 2313 and the sleeving columns 2321, meanwhile, the whole pressing cover 231 is embedded in the adjusting cover 232, a cavity matched with the pressing cover 231 is arranged below the adjusting cover 232, and accordingly the pressing cover 231 can move axially in a balanced mode relative to the adjusting cover 232, and inclination in the moving process is avoided; thus, the shallow grooves 2311 and the deep grooves 2312 can be better matched with the positioning blocks 221 on the wheel shaft 22, so that the stability of the product structure is improved.
So that the pressing cover 231 can only move in the axial direction with respect to the regulating cover 232; the socket post 2321 is provided with a threaded hole, the fastening screw is in threaded fit with the threaded hole, the pressing cover 231 is installed on the adjusting cover 232, and under the action of the pressing spring, the pressing cover 231 can move inside and outside the adjusting cover 232 relatively.
The outer side wall of the adjusting cover 232 is provided with a grip 2322 protruding outwards, so that people can rotate the adjusting cover 232 conveniently.
The wheel 21 comprises a rear cover plate 211, a front cover plate 212 and a middle soft rubber 213 arranged between the rear cover plate 211 and the front cover plate 212, wherein the front cover plate 212 and the rear cover plate 211 are mutually clamped into a whole; the middle part of the front cover plate 212 is provided with a mounting groove 2121 for mounting the friction pad 214 in an inward concave manner, when the pressing cover 231 presses the friction pad 214 inwards, the bottom wall of the mounting groove 2121 can continuously rub against the friction pad 214 during the rolling process of the wheel 21, so that the wheel 21 is prevented from rolling.
The wheel assembly 2 is detachably arranged on the frame 1, and when the cart is sold, the wheel assembly 2 is in a state to be installed, so that logistics transportation is facilitated; the stud 3 sequentially penetrates through the frame 1 and the wheel shaft 22 to be matched with the nut 4, the wheel shaft 22 is fixedly arranged on the frame 1, and after the trolley is received, the stud 3 and the nut 4 can be used for integrally installing and fixing the wheel assembly 2, so that the operation is simple and convenient; the novel handcart further comprises a decorative cover 5 which can shade the nut 4, so that the appearance of the handcart is more attractive.
