A supermarket shopping trolley with variable telescopic distance and its realization method

Abstract

The invention discloses a nesting-distance variable supermarket trolley. The nesting-distance variable supermarket trolley comprises a handlebar, handrail net mounting parts, a handrail net, a basket, anti-collision parts, an underframe, castors and snap joints. The handlebar is connected with the upper end of the basket. A cross beam is arranged at the upper end of the basket. The two ends of the cross beam are provided with the handrail net mounting parts respectively. The handrail net is connected with the handrail net mounting parts. The underframe is connected with the basket through the snap joints. The anti-collision parts are arranged at the bottom of the basket. The underframe comprises underframe tubes, a front connecting tube, a front locating rod, a rear locating rod, a lower connecting rod, connecting plates and castor mounting plates. The invention further discloses an implementation method of the nesting-distance variable supermarket trolley. The nesting-distance variable supermarket trolley overcomes the defects that in the prior art, a supermarket trolley is small in loading capacity, high in transport cost, large in occupied space, capable of scratching the outer surface of a vehicle, low in production efficiency, short in service life and the like. The nesting-distance variable supermarket trolley has the advantages of being simple in structure, low in manufacturing cost, small in nesting distance, high in loading capacity, low in transport cost, low in manufacturing cost, long in service life and the like.

Description

technical field [0001] The invention relates to supermarket shopping trolley technology, in particular to a supermarket shopping trolley with variable telescoping distance and its realization method. Background technique [0002] With the development of society, supermarkets can be seen everywhere, and supermarket shopping trolleys have brought convenience to people. The structural properties of known supermarket shopping trolleys mainly contain the following two types: one is such as the Chinese patent authorization announcement number CN201520320U and the Chinese invention patent authorization announcement number The disclosed structure of CN100420599C is composed of a vehicle frame and a frame body equipped with rollers, and the frame body is fixed on the vehicle frame. The frames of this structure are all composed of grid-like meshes, which include bottom meshes and front, rear, left and right meshes. In most cases, the bottom meshes are made of plastic plates. , while ...

AI Technical Summary

Problems solved by technology

[0004] 1. In the actual transportation and use process, the telescopic distance of the front and rear supermarket shopping trolleys is fixed and relatively large, which is not conducive to the realization of large-scale packing and transportation, and the transportation cost is high;

[0005] 2. Due to the large stacking distance and large storage space, it will increase the additional expenditure of the supermarket;

[0006] 3. When nesting, there is no protective device, and there will be scratches between the vehicles, which will affect the appearance and service life;

[0007] 4. The rotating bar in the handrail net installation part is set vertically, and the service life is short;

[0008] 5. The bottom frame is made of steel pipes bent many times, the process is complicated, the production cost is too high, the consistency of the parts is poor, and the production efficiency is low
