supermarket trolley

Abstract

A trolley used in a supermarket comprises a frame formed through plastic molding, a trolley body jointly composed of a bottom frame piece, a front frame piece, a rear frame piece, a left frame piece and a right frame piece and enclosing a trolley body cavity, and a child seat, and is characterized in that a trolley body supporting seat is arranged at the end, facing the left frame piece, of the frame, a bottom frame piece supporting seat embedding cavity is formed in the upward side of the trolley body supporting seat, a bottom frame piece supporting seat is arranged at the bottom of the end, facing the left frame piece, of the bottom frame piece, the end, facing the rear frame piece, of the bottom frame piece supporting seat extends to the bottom of the rear frame piece, the end, facing the right frame piece, of the bottom frame piece corresponds to the upper portion of the end, facing the right frame piece, of the frame, the upper portion of the left frame piece is connected between a front frame piece hand-pushing rod seat and a rear frame piece hand-pushing rod seat, the lower portion of the left frame piece is a rotary free end, and the left side of the left frame piece is blocked by the upper edge of the end, facing the left frame piece, of the bottom frame piece. Resources and costs are saved, the manufacturing efficiency is high, an overall effect is good, and the trolley facilitates that heavy-weight commodities are put in or moved out of the trolley body cavity and is recyclable, good in safety, environmentally friendly and long in service life and ensures sanitation.

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 for supermarkets are also called supermarket shopping trolleys. In the published Chinese patent literature, there is no shortage of technical information on trolleys for supermarkets, such as CN201520320U (a novel shopping trolley for supermarkets), CN202147705U (shopping trolleys for supermarkets), CN10414982A (a shopping trolley for supermarkets) and CN201042965Y (a shopping trolley for supermarkets). ),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 ...

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 "shopping trolley" disclosed in Chinese Invention Patent Publication No. CN86104091A is not limited to the fact that many technical problems mentioned above are basically eliminated due to the use of thermosetting molding compound compression molding, but the CN86104091A has the following shortcomings: First, due to the (The patent is called the basket) The arm (the patent is called the arm extending backward) and the rear wall are integrated with the frame, so when any of the car body, arm and rear wall is damaged, it can only be replaced as a whole. Waste is all waste, thereby causing waste of resources; second, because the aforementioned arm, rear wall and vehicle frame become an integral structure, thus the front wall, left and right walls and bottom wall of the vehicle body need to be connected with the rear wall, the arm and even the vehicle body respectively by means of assembly. Therefore, it is not only cumbersome to assemble, but also the overall stability effect is poor; third, because the storage cavity of the car body is an integral cavity without partitions, customers often encounter confusion when shopping, for example, when customers at the same time When purchasing water-repellent items (items that are afraid of water and oily contamination), wet products, or even raw or cooked food, it is often necessary to separate water-repellent items from wet products to avoid mutual interference; Any one of the walls (also known as the frame, the same below) cannot be flipped upwards and returned downwards as needed, that is, it does not have the effect of opening and closing the door. Therefore, when putting heavy goods into the car body cavity or from the When the car body cavity is taken out, it is often impossible to take and place it in a manner of translation or horizontal movement, so it is more laborious to take and place the goods; The structure is relatively complicated and the stability of the seat board is relatively fragile
