Description

Foldable single-tier shopping trolley

technical field

The invention relates to a shopping cart, in particular to a foldable single-layer shopping trolley.

Background technique

At present, most of the hand-push shopping carts are not foldable, which takes up a large space and is inconvenient to store and carry. Even the foldable shopping cart has a large volume after being folded, and is inconvenient to carry and store, and the existing foldable shopping cart has a complex structure, complicated folding and unfolding, and cannot be completed in one step.

Contents of the invention

The object of the present invention is to provide a foldable single-layer shopping trolley with small volume after folding, large volume after opening, fast folding and opening, and simple structure.

In order to achieve the above object, the technical solution adopted by the present invention is: a foldable single-layer shopping trolley, including a support frame, a handle and a basket frame, the support frame is composed of four symmetrical support rods and two transverse Composed of rods, the front and rear support rods on the left are cross-hinged, the front and rear support rods on the right are cross-hinged, and the two cross bars are respectively connected with the left and right symmetrical support rods; the handle is connected with the support frame; the loading The front end of the basket frame is hinged with the front support bar, and the rear end of the loading basket frame is connected with the rear support bar.

Preferably, the handle is arranged on the rear support rod of the main support frame, and is socketed with the rear support rod.

Preferably, the front end of the loading basket frame is hinged to the front support rod through a connecting piece.

Preferably, the rear end of the loading basket frame is fastened to the rear support rod.

After the present invention adopts the above-mentioned structure, the supporting frame adopts four symmetrical support rods and two cross-bar structures. The symmetrical support rods are connected; the handle is connected with the support frame; the front end of the loading basket frame is hinged with the front supporting rod, and the rear end of the loading basket frame is connected with the rear supporting rod; The buckle between the support rods and the basket frame push the upper ends of the front and rear support rods to swing down at the same time, so that the front and rear support rods and the load basket frame overlap together to complete the folding of the shopping cart in one step, and after folding, the volume is small and convenient Carrying and storage; when unfolding, pull the rear end of the basket frame and lift it up, and at the same time, the upper ends of the front and rear support rods swing up to the rear end of the basket frame and buckle with the rear support rod to complete the opening of the shopping trolley , Its opening is also in place in one step, very convenient, and the expansion volume is large, and there are many loads.

A further improvement is that the handle is arranged on the rear support rod of the main support frame and is socketed with the rear support rod, so the handle can be extended into the support rod when folded, so that the folded shopping trolley is smaller in volume.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Shown in Figures 1, 2, 3, 4, 5, 6, 6 and 7, the foldable single-layer shopping trolley of the present invention includes a support frame 1, a handle 2 and a loading basket frame 3, and the support frame 1 is symmetrical from left to right. The four support rods 11a, 11b, 11c, 11d and two cross bars 11a, 11b, 11c, 11d are composed of the front and rear support rods 11a and 11b on the left, and the front and rear support rods 11c and 11d on the right are cross-hinged , the two cross bars 12a, 12b are respectively connected with the left and right symmetrical support bars 11a, 11b, 11c, 11d; the handle 2 is connected with the support frame 1; the front end of the basket frame 3 is hinged with the front support bars 11a, 11c , the rear end of the basket frame 3 is buckled with the rear support rods 11b, 11d through the buckle 4. The buckle 4 in this embodiment is two blocks, which are buckled together when buckled together. In this embodiment, the handle 2 is set on the rear support rods 11b, 11d of the main support frame 1, and is socketed with the rear support rods 11b, 11d, so the handle 2 can be inserted into the support rod when folding, so that the folding The latter shopping trolley is smaller in volume, and the handle 2 is pulled out of the support bar when unfolded. The front end of the loading basket frame 3 is hinged to the front support rods 11a, 11c through the connecting piece 5 .

In the folded state, pull the rear end of the basket frame and lift it up, and at the same time, the upper ends of the front and rear support rods swing up to the rear end of the basket frame and the rear support rod to buckle it, thus completing the shopping cart. It can be opened in one step, which is very convenient, and it has a large volume and loads.

In the unfolded state, open the buckle between the load basket frame and the rear support rod, the load basket frame pushes the upper ends of the front and rear support rods to swing down at the same time, so that the front and rear support rods and the load basket frame overlap together, one step in place, and fold The rear volume is greatly reduced, which saves the display space and is convenient to store and carry.

The above description is only a preferred embodiment of the present invention, and of course it cannot limit the scope of rights of the present invention. It should be pointed out that for those of ordinary skill in the art, the technical solutions of the present invention can be modified or equivalently replaced. Without departing from the essence and scope of the technical solution of the present invention.
