Preferably, the side parts of the first sleeve and the second sleeve are respectively provided with a fastening bolt in a threaded manner.

Preferably, a vertical stop lever is arranged at the top of the front end of the longitudinal beam.

Preferably, the folding arm mechanism comprises a first connecting rod and a second connecting rod which are hinged, and a self-locking folding hinge is arranged at the hinged position of the first connecting rod and the second connecting rod.

Preferably, the outside of the longitudinal beam is provided with an edge beam, the edge beam and the longitudinal beam are arranged in parallel, and the edge beam and the longitudinal beam are connected through a plurality of third connecting rods; and two ends of the third connecting rod are respectively hinged with the longitudinal beam and the side beam.

Compared with the prior art, the utility model has the following advantages:

the folding trolley is convenient to carry along with the vehicle after being folded, so that the occupied space is greatly reduced; the folding trolley can be used by two wheels and four wheels, and the two using states can meet the transportation requirements of different cargoes; the longitudinal beam, the side beam and the connecting rod of the folding trolley are all made of square tubes, the weight of the folding trolley is lighter, and the original bearing weight is not affected.

Drawings

FIG. 1 is a schematic perspective view of the present utility model;

FIG. 2 is a top view of FIG. 1;

fig. 3 is a schematic view of the unfolded state of fig. 2.

In the figure: 1. the side beam comprises a longitudinal beam body, 2, an inserting rod, 3, a first connecting rod, 4, a second connecting rod, 5, a caster, 6, a first sleeve, 7, a second sleeve, 8, a fastening bolt, 9, a stop lever, 10, a side beam, 11 and a third connecting rod.

Detailed Description

The utility model is further illustrated by the following examples in connection with the accompanying drawings.

Example 1

Referring to fig. 1-3, a multipurpose folding trolley comprises two side-by-side longitudinal beams 1 and two inserting rods 2 serving as handrails, wherein the two longitudinal beams 1 are connected through three groups of folding arm mechanisms, two ends of each folding arm mechanism are respectively hinged with the two longitudinal beams 1, the front side and the rear side of the bottom of each longitudinal beam 1 are respectively provided with a caster wheel 5, and the casters 5 on the front side are universal wheels; the rear end of the longitudinal beam 1 is fixed with a horizontal first sleeve 6 and an upward inclined second sleeve 7, one end of the inserted link 2 is inserted into the first sleeve 6 or the second sleeve 7, and the side parts of the first sleeve 6 and the second sleeve 7 are respectively provided with a fastening bolt 8 in a threaded manner.

In more detail, the top of the front end of the longitudinal beam 1 is provided with a vertical stop lever 9.

In more detail, the folding arm mechanism comprises a first connecting rod 3 and a second connecting rod 4 which are hinged, and a self-locking folding hinge is arranged at the hinged position of the first connecting rod 3 and the second connecting rod 4.

When the folding trolley is transported, the folding arm mechanism is in the folding state shown in fig. 2, at the moment, the two longitudinal beams 1 are close to each other, the width of the trolley is shortened, the inserting rod 2 is pulled down, the length of the trolley is shortened, and at the moment, the trolley can be carried along with the trolley, so that the occupied space is greatly reduced; when the folding trolley is required to be used, the folding arm mechanism is unfolded, so that the first connecting rod 3 and the second connecting rod 4 are in a straight shape and are locked through the self-locking folding hinge; inserting the inserted link 2 into the first sleeve 6, and then fixing by tightening the fastening bolt 8, wherein the trolley is in a two-wheel use state; inserting the inserted link 2 into the second sleeve 7, and then fixing the inserted link by tightening the fastening bolt 8, wherein the trolley is in a four-wheel use state; the two using states can meet the transportation requirements of different cargoes.

The folding trolley is convenient to carry along with the vehicle after being folded, so that the occupied space is greatly reduced; the folding trolley can be used by two wheels and four wheels, and the two using states can meet the transportation requirements of different cargoes.

Example two

As a preferred embodiment of the present utility model, the present embodiment adds the side sill 10 on the basis of the first embodiment, specifically:

in the embodiment, the outer side of the longitudinal beam 1 is also provided with a boundary beam 10, the boundary beam 10 is arranged in parallel with the longitudinal beam 1, and the boundary beam 10 and the longitudinal beam 1 are connected through four third connecting rods 11; both ends of the third connecting rod 11 are hinged with the longitudinal beam 1 and the side beam 10 respectively.

When the trolley is used, the side beam 10 is unfolded, so that the third connecting rod 11 is in a vertical state with the longitudinal beam 1 and the side beam 10, and the width of the trolley is lifted, so that more cargoes can be transported. When the folding trolley is transported, the side beam 10 is retracted.

The longitudinal beam 1, the side beam 10 and the connecting rod of the folding trolley are all made of square tubes, the weight of the folding trolley is lighter, and the original bearing weight is not affected.

The present utility model is not limited to the above-described embodiments, and various changes may be made without departing from the spirit of the present utility model within the knowledge of those skilled in the art, and the contents after the changes still fall within the scope of the present utility model.
