Supermarket trolley

Abstract

The invention provides a supermarket trolley, which includes a frame, a car body, a front frame piece manual push rod seat, a rear frame piece manual push rod sea and a manual push rod. Travelling wheels are arranged at the bottom of the frame, the car body is composed of a bottom frame piece, a front frame piece, a rear frame piece, a left frame piece and a right frame piece, and the car body issupported on the frame. The supermarket trolley has the characteristics that a front frame piece inserting pipe is arranged at the left end of the front side of the frame, a rear frame piece insertingpipe is arranged at the left end of the rear side of the frame, a front frame piece left longitudinal pipe is arranged at the left end of the front frame piece, a rear frame piece left longitudinal pipe is arranged at the left end of the rear frame piece, the front frame piece left longitudinal pipe is inserted in the upper end of the front frame piece inserting pipe, the rear frame piece left longitudinal pipe is formed in the upper end of the rear frame piece inserting pipe, the front frame piece manual push rod seat is connected with the upper end of the front frame piece inserting pipe ininserted and embedded modes, the rear frame piece manual push rod seat is connected with the upper end of the rear frame piece inserting pipe in inserted and embedded modes, and the manual push rod is arranged between the opposite sides of the front frame piece manual push rod seat and the rear frame piece manual push rod seat; and the upper part of the left frame piece is connected between the opposite sides of the front frame piece left longitudinal pipe and the rear frame piece left longitudinal pipe, and the left side of the lower part of the left frame piece is in contact with a left frame piece crosspiece between the opposite sides of the lower ends of the front frame piece inserting pipe and the rear frame piece inserting pipe. The car body size is reduced, and the logistics cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of commercial facilities, and in particular relates to a trolley for supermarkets. Background technique [0002] The aforementioned trolleys used in supermarkets are also called supermarket shopping trolleys. There is no lack of relevant technical information in the published Chinese patent literature, such as CN201520320U (a novel supermarket shopping trolley), CN202147705U (a supermarket shopping trolley), CN10414982A (a supermarket shopping trolley) and CN201042965Y (a shopping trolley ),and many more. [0003] Since it is not limited to the frame and body of the supermarket trolleys listed above are all made of metal, as far as the body is concerned, the front, rear, left, and right meshes (that is, the four side walls) and the bottom mesh are made of hollowed-out metal. Wire, and in order to ensure a reasonable service life, all the aforementioned meshes need to be electroplated. This type of trolley...

AI Technical Summary

Problems solved by technology

This type of trolley for supermarkets has the following disadvantages: one, because the mesh cannot be molded with a mold, the production efficiency is low, which is not conducive to the requirements of industrialized enlarged production; Welding, so the production process is cumbersome and economical and cheap; third, because all meshes need to be electroplated on the surface and the electroplating pollution is serious, thus detrimental to environmental protection; fourth, because metal materials are used and the recycling effect is poor , thus consumes a lot of resources; fifth, because it is susceptible to environmental factors, it will rust or even peel off the coating. If the old one is not replaced in time, it will damage the appearance and even damage the goods. In severe cases, it will cause unsafe factors such as scratched shopping The limbs, clothing, etc. of the wearer; Sixth, it is not conducive to maintaining a good appearance for a long time, it is not conducive to maintenance, and it cannot withstand the erosion of strong detergents, steam, solvents or other cleaning fluids; Seventh, due to the The pieces are hinged to form a whole. Because of the loud noise and easy damage in the actual use process, it will affect the service life within a reasonable period.

[0004] The deficiencies in the above seven aspects are made up by the "shopping trolley" disclosed by CN86104091A, and the deficiency of this CN86104091A is eliminated by the "supermarket trolley" provided by CN105936285B. However, there are still the following disadvantages: one, because the front and rear frame hand push rod seats are respectively formed by the extension of the front and rear frames, the maximum width and overall length of the car body are significantly increased and the overall volume is increased. The logistics cost is relatively high; secondly, because the shape and structure changes of the front and rear frame push rod seats are relatively active parts on the trolleys used in supermarkets, a user such as a supermarket or a professional trolley seller has put forward a change request. Professional manufacturers can only remanufacture the entire car body together with the front and rear frame hand push rod seats, so on the one hand, the manufacturing cost is increased, and on the other hand, resources are wasted. It increases the cost and simultaneously limits the diversity and flexibility of the design of the front and rear frame push rod seats, because the change of the front and rear frame push rod seats needs to take into account the remanufacturing cost of the entire car body; The seat is extended on the front and rear frames, and its strength itself is limited. Once damaged, it can only be replaced together with the entire car body, which increases the cost of use; However, while ensuring the flexible rotation of the turning axis of the left frame piece, there is also a situation where the turning axis of the left frame piece moves, especially when the left frame piece may be damaged due to aging and deformation after a period of use. The turning shaft protrudes from the supporting hole on the push rod seat of the front and rear frames, thus endangering the safety of children
