Description
Technical Field
The invention belongs to the technical field of commercial facilities, and particularly relates to a supermarket shopping trolley with a built-up car body.
Background
Supermarket shopping carts are not known in the published chinese patent literature, such as CN86104091a (shopping cart), CN201042965Y (shopping cart), CN201520320U (a novel supermarket shopping cart), CN101979267B (supermarket shopping cart), CN201842117U (supermarket shopping cart), CN202147705U (supermarket shopping cart), CN104149827a (a supermarket shopping cart), CN10414982a (a supermarket shopping cart), and the like.
The supermarket shopping trolley is divided into two major categories from the material, namely metal and plastic, and as for the vehicle body made of the metal, the front, back, left and right net sheets (namely four side wall bodies) and the bottom net sheet are formed by hollowed-out metal wires, and all the net sheets need to be subjected to electroplating treatment in order to ensure the service life within a reasonable period. The cart for supermarkets has the following general disadvantages: firstly, the mesh sheet cannot be molded by using a die, so that the manufacturing efficiency is low, and the requirement of industrial amplified production is difficult to meet; secondly, the ribs of the net sheet and the net sheet frame are required to be welded, so that the manufacturing process is troublesome and uneconomical and low in cost; thirdly, all the meshes are required to be subjected to surface electroplating, and electroplating pollution is serious, so that the environment is damaged; fourth, because the metal material is adopted and the recycling effect is poor, the resource consumption is high; fifthly, because the rusting and even the coating are easily peeled off due to the influence of environmental factors, if old and new products are not timely discarded, the objects are damaged, the objects are even damaged, and unsafe factors such as the limbs, clothes and the like of shoppers are scratched when serious; sixth, it is not advantageous to permanently maintain a good appearance, nor to maintain, nor to withstand the intense attack of detergents, vapors, solvents or other cleaning fluids; seventhly, as the meshes are hinged to form a whole, the meshes are large in noise and easy to damage in the actual use process, and the service life of the meshes in a reasonable period is influenced. The latter plastic vehicle body can be molded by a mold, and does not require welding, plating, or the like, and therefore has high productivity and low cost. Based on the aforementioned factors, which are not limiting examples, plastic supermarket shopping carts are currently dominant in the supermarket industry, while metal supermarket carts are gradually fading out of the market.
A typical example of a supermarket shopping cart with a plastic body is a "supermarket cart" as recommended by the invention of patent application publication No. CN105936285A, which compensates for the deficiencies of the "shopping cart" provided by the aforementioned CN86104091a, which is also plastic, and objectively reflects the advantages of the eight aspects of the disclosure in the technical effects column of the specification.
The aforementioned CN105936285a still suffers from the following drawbacks: firstly, because preceding frame piece comprises preceding frame piece body and preceding frame piece push rod seat, the back frame piece comprises back frame piece body and back frame piece push rod seat, because the position of the push rod of order about shopping cart walking is located between preceding, back frame piece push rod seat again, still because left frame piece is connected equally between preceding, back frame piece push rod seat, and then because child seat's seat pan pivot is placed on the left frame piece, therefore the atress of preceding frame piece push rod and back frame piece push rod is big, the yielding, fracture is even disconnected, and CN105936285A constitutes integrated structure with preceding frame piece body with preceding frame piece push rod seat and constitutes integrated structure with back frame piece push rod seat and back frame piece body self-evident that the drawback is: when the front frame piece hand-push rod seat or the rear frame piece hand-push rod seat is damaged, the whole car body (the front frame piece body, the rear frame piece body, the right frame piece body and the bottom frame piece) except the left frame piece, the child seat and the car frame can only be replaced together, so that on one hand, the resource waste is caused, and on the other hand, the cost of the supermarket provided with the shopping trolley is increased; secondly, regarding information fed back from shops and supermarkets, the probability of damaging the front frame slice hand-push rod seat and the rear frame slice hand-push rod seat is highest relative to the whole shopping trolley, and targeted local replacement cannot be implemented, however, beneficial suggestions for solving the problem are not given in patent and non-patent documents including CN 105936285A.
In view of the above prior art, there is a need for rational improvement, for which the applicant has devised an active and advantageous design and has developed the solution to be described below.
