Novel supermarket shopping cart

Abstract

The invention discloses a novel supermarket shopping cart, which comprises an integrated basket, a frame, a basket supporting cross beam, a handrail and a backboard, wherein a pipe plug device is arranged on the rear sides of the two side walls of the basket respectively; the frame comprises a first bent beam and two stand pipes which are formed by upwardly bending the two ends of the bent beam respectively; the two stand pipes are plugged into the pipe plug devices; the basket supporting cross beam is bridged between two bent sections of the bent beam and is buckled at a connection clamp position on the bottom surface of the basket; the two ends of the handrail are fixedly sleeved on the parts of the stand pipes which extend out of the upper ends of the pipe plug devices; the pipe plug devices are limited between the end part of the handrail and the bent parts of the bottom end parts of the stand pipes; and the upper part of the backboard is arranged on and connected to the handrail. According to the novel supermarket shopping cart, an integrated structure is adopted by the basket; the pipe plug devices at the rear ends on the two sides of the basket are fixed with the stand pipes of the frame in a casing mode; the bottom of the basket is fixed with the basket supporting cross beam on the frame in a clamping mode; the handrail, the tail ends of the stand pipes and the backboard are connected through screws; and the mounting is convenient and the connection strength and the stability are high.

Description

[0001] technical field [0002] The invention relates to the technical field of carts, in particular to a novel supermarket shopping cart. [0003] Background technique [0004] With the continuous increase of the supermarket scale and the continuous increase of people's shopping needs, the shopping cart has become a necessary shopping auxiliary device in the supermarket. [0005] Traditional shopping carts usually include a frame and a frame. The frame is welded and fixed on the frame, and the wheels are installed at the bottom of the frame. Since the frame is made of iron wire or stainless steel, more manpower is required for production, and the manufacturing process is complex and efficient. Low, at the same time need welding, spraying and other follow-up processes, the car body is also relatively heavy, and it is more laborious to push. [0006] At this stage, in order to reduce the weight of the car body, there is another shopping cart basket made of plastic material....

AI Technical Summary

Problems solved by technology

[0005] Traditional shopping carts usually include a frame and a frame. The frame is welded and fixed on the frame, and the wheels are installed at the bottom of the frame. Since the frame is made of iron wire or stainless steel, more manpower is required for production, and the manufacturing process is complex and efficient. Low, at the same time need welding, spraying and other follow-up processes, the car body is also relatively heavy, and it is more laborious to push

[0006] At this stage, in order to reduce the weight of the car body, there is another shopping cart basket made of plastic material. The side walls of the basket are processed and formed by injection molding process, and then these side walls are assembled, and then assembled with the frame. The front side wall, left side wall, right side wall, rear side wall and bottom wall need to be formed by five sets of molds, the cost of the mold is high, and it is difficult to ensure that the assembled basket can be accurately installed with the frame

[0007] In view of the above defects, the patent document with the publication number CN201842117 discloses a frame made of plastic material, the bottom wall of which is fixed on the frame, the front side wall, the left side wall and the right side wall are integrally formed, and the rear side wall is hinged. On the two standpipes of the frame, although this kind of shopping cart has solved the problems and deficiencies of the traditional shopping cart frame using metal material or plastic frame body forming each side wall separately, in the actual use process, due to The integrally formed U-shaped frame body still needs to be tenoned with the bottom wall or fixedly assembled in other ways. There are still certain dimensional accuracy requirements for the bottom wall and U-shaped integrated frame during installation. If there is an error, it may bring trouble to the installation work. Trouble; moreover, the U-shaped frame and the bottom wall are independent, and the complicated connection method between the U-shaped frame and the standpipe still has the problems of low strength and unstable structure
