Description

Trolley for supermarket

Technical field

The invention belongs to commercial facility technical field, and in particular to a kind of Trolley for supermarket.

Background technology

Foregoing Trolley for supermarket is also referred to as Supermarket trolley.It is no lack of in disclosed Chinese patent literature and is seen in supermarket With the technical information of trolley, such as CN201520320U（A kind of novel Supermarket trolley）、CN202147705U（Supermarket Use shopping cart）、CN10414982A（A kind of supermarket shopping car）And CN201042965Y（Shopping cart）, etc..

Because the vehicle frame and the car body that are not limited to Trolley for supermarket exemplified above are made using metal, with regard to car For body, its all around mesh sheet（That is four sidewall bodies）And spacer screen piece is made up of the wire of Openworks shape, and in order to ensure Adequate service life all needs to make electroplating processes to foregoing all mesh sheet.Following logical disadvantage be present in this Trolley for supermarket：First, by In mould can not be used to be molded mesh sheet, thus producing efficiency is relatively low, is unfavorable for industrial amplification production requirement；Second, due to The rib of mesh sheet need to be welded with mesh sheet frame, thus manufacturing process is troublesome and loses relatively cheap；Third, by need to institute There is mesh sheet to carry out electroplating surface and electroplate seriously polluted, thus damage environmental protection；Fourth, due to using metal material and Recycling effect is poor, thus resource consumption is big；Fifth, due to easily being got rusty by environmental factor or even plating exfoliation, if Trade-in is abandoned not in time, then is damaged sight or even is brought disaster to article, can also trigger unsafe factor such as to scratch shopper when serious Limbs, clothing etc.；Sixth, being both unfavorable for enduringly keeping good outward appearance, also it is unfavorable for maintaining and can not being subjected to stronger Detergent, steam, solvent or other cleaning fluids etch；Seventh, due to being to form one by be hinged between each mesh sheet Overall, because noise is big and fragile during the use in reality, influence the service life in the reasonable time.

" shopping Cart " is as a result of thermoset molding disclosed in Chinese invention patent publication number CN86104091A Expect compression molding, thus be not limited to above mentioned many technical problems and be substantially eliminated, but the CN86104091A Following shortcoming be present：First, due to car body（Patent claims small basket）Arm（Patent claims the arm extended backward）And rear wall is and car Framework becomes one structure, thus when car body, arm and any damage of rear wall three, can only integrally replace it is i.e. one useless all useless, So as to cause the wasting of resources；Second, because foregoing arm, rear wall and vehicle frame are integrally constituted structure, thus the antetheca of car body, a left side Right wall and bottom wall need to be connected with rear wall and arm or even vehicle frame respectively by assembly method, thus not only assembling trouble, and whole The stablizing effect of body is poor；Third, because the object placing cavity of car body is that car body chamber is an overall chamber without separation, thus customer is purchasing Puzzlement is often run into during thing, such as when customer while acquisition water repellent article（The article afraid of water for being afraid of oiliness contamination）, wet product or even During raw or ripe food, generally require to separate water repellent article and wet product etc., avoid mutually producing interference effect；Fourth, by In any one wall body of car body（Also referred to as frame piece, it is as follows）That is, can not have according to need to be flipped up and reply downwards Open the door, the effect as shutdown, thus often can not be with flat when heavier commodity are put into car body chamber or taken out from car body chamber Move the mode moved horizontally to pick and place, it is more laborious then to pick and place commodity；Fifth, due to the child seat being matched on trolley Chair is by shelf, seat board（That is stool plate）, U-shaped extension, push pedal rear baffle（That is backrest）, pivot and pivotal point etc. form, thus Structure is complex, and the stability of seat board is more fragile.

For above-mentioned prior art, it is necessary to improved, for this, the applicant has made positive and beneficial design, finally Form technical scheme described below and simulate deduction experiment through computer in the case where taking secrecy provision and be proved to be It is practicable.

The content of the invention

The task of the present invention be to provide a kind of package assembly for helping to make car body and vehicle frame to be configured to building block system and by Economized on resources with pointedly changing the vehicle frame of the car body of damage or damage and embodiment, be advantageous to improve the system of car body and vehicle frame Make efficiency and embody excellent whole structure and use and meet industrial amplification production requirement and ensure reliable in use Property, the structural system for being beneficial to make car body left frame piece according to need to upwards start or reply downwards and use by the big commodity of weight with Move horizontally mode be effortlessly put into or remove car body chamber, have be easy to abandon it is recyclable after welding is scrapped with plating and guarantee Property and use and avoid undermining environment in the fabrication process and embody recycling, helping to prevent in use for resource Use and embodied well because of such as the undermining the dress ornament of commodity and shopper or even the situation of limbs of car body self reason appearance Safety in utilization, be advantageous to promote corrosion resistance and use and periodically and easily using detergent or even steam implementation cleaning disappear Poison and it is beneficial to avoid to produce noise during use between the frame piece of car body and between frame piece and vehicle frame and use and avoid Influence shopping environment and ensure the Trolley for supermarket of good service life.

Another task of the present invention is to provide a kind of car body chamber rationally separation contributed to car body and using to place Avoid producing the Trolley for supermarket of interference effect each other in the endoceliac commodity isolation of different nature of car.

The another task of the present invention is to provide a kind of knot for being advantageous to significantly simplify the children's seat being mounted on car body Structure and ensure excellent stability and use the Trolley for supermarket for embodying preferable security.
