Further, the support rod includes telescopic rod interconnected and fixed link, the telescopic rod and the collet Hingedly, second connecting shaft is arranged in the fixed link.

The beneficial effect of collapsible supermarket trolleys provided by the utility model is:

1, collapsible supermarket trolleys provided by the utility model, compared with prior art, by traditional supermarket trolleys It is changed to upper and lower structures, the scattered commodity storing part that upper layer is surrounded by shopping box, lower layer is flat by being similar to of constituting of collet The large item storage area of wooden handcart structure.Wherein, shopping box design size meets the requirement of general-utility car boot size, can be without barrier Hinder placement；And shopping box and vehicle frame use detachable connection method, can as needed separate shopping box with car body (vehicle frame), it is single Solely use.And vehicle frame uses folding structure, is carried out folding storage according to vehicle frame service condition convenient for user, ensure that Its convenience for using and carrying.Existing product in the market, such as bicycle lock, plug-in unit product can be used in clamping lock, as long as energy Realize that angle immobilizes in use between each connector (including collet, support frame, handrail and bracket).

In addition, the support frame in vehicle frame may also be configured to stretching structure, the height-adjustable of shopping box is realized, when use can Shopping box bottom is adjusted to rear-box bottom and is flushed, directly shopping box is put in boot convenient for user, is further dropped Labor intensity when low shopping box is carried.This product realizes binding directly for trolley and automobile trunk, is suitable for house Front yard or multiple good friends do shopping together, and use when causing transport difficult that purchase article is more effectively increases the convenience of life, increases The experience of supermarket shopping streamlined (directly get on the bus and get home) is added.At the same time, similar shared bicycle can also be installed additional on vehicle frame Lock, two dimensional code of formula etc. realize the intelligent management of supermarket trolleys, the loss of trolley are avoided, convenient for the popularization of this product.

2, in the utility model each clamping lock (including the first clamping lock, the second clamping lock and third clamping lock) upper part be correspondingly connected with Hingedly, lower part is detachably connected part (including handrail, bracket and support frame) with part (including support frame and collet) is correspondingly connected with, and is protected The planarization for having demonstrate,proved each connector top surface avoids the phenomenon that commodity that user buys are scratched by clamping lock, ensures simultaneously The safety that trolley uses meets its requirement.In addition, can also install protective jacket additional outside clamping lock, it is ensured that when clamping lock uses Safety.

First clamping lock, the second clamping lock and third clamping lock are set as two, and are symmetricly set on vehicle frame two sides, ensure that each company The consistency of fitting two sides stress, it is ensured that the integrally-built stability of vehicle frame.The setting of fixing piece, which realizes each clamping lock, not to be made The fixed storage of used time, avoiding it, arbitrarily swing causes trouble to vehicle frame movement, while reducing each clamping lock and sending out when not in use The risk of raw abrasion.Each clamping lock is made of metal material, and fixing piece uses magnetic force block or snap ring, ensure that fixing piece and each card The quick of lock connects and separates, and further ensures the fast folding of vehicle frame and packs up, it is ensured that its convenience used.Using It then further reduced each clamping lock when magnetic force block to pack up repeatedly or using the risk worn, it is ensured that trolley is longer to be made Use the service life.

Each clamping lock uses arc fastener, and structure is simple, easy to maintenance, in use, can will be blocked by bolt or inserting mode Part is fixed, and realization is correspondingly connected with being connected and fixed between part, ensure that it is good to the support effect of corresponding connector.Together When, for arc fastener compared to linear type fastener, the stress of arc fastener unit length is much smaller than linear type fastener, therefore uses The risk that Cheng Zhongqi deforms is smaller.
