Trolley

Abstract

The invention discloses a trolley, which comprises a first plate, a first frame tube, a second plate, a second frame tube, a wheel set and at least one handle. The two sides of the first plate are respectively fixed with a first main frame, and the two first main frames are respectively provided with a slit groove in different directions, and the two slit grooves are respectively arranged parallel to the long axis direction of the first main frame. The second plate frame is arranged on the outer periphery of the first plate, the second frame tube is respectively provided with two second main frames, the two second main frames are respectively pivoted through the two first main frames, and the two second main frames correspond to two A fin is respectively provided at the grooved position of the first main frame, each fin is fixed with the second plate, and the wheel set is arranged under the first frame tube and the second frame tube, and the handle is located on the first cross bar or the second frame tube. The position of the second crossbar. The invention can conveniently adjust the length of the bearing surface, carry the goods stably, save labor, be smooth and easy to use.

Description

Technical field [0001] The invention is applied to the technical field of trolleys for transporting goods, in particular to a trolley that can increase the carrying capacity. Background technique [0002] Generally, whether it is a household or a factory when handling small goods, trolleys or trolleys are used to carry goods to save effort. However, generally known trolleys only have a fixed-size load-bearing surface, and larger-size goods cannot be transported, which causes problems in use. [0003] Therefore, there are also trolleys on the market that can adjust the size of the load-bearing surface. This type of trolley can only be extended and retracted by the frame tube. If the plate is to be installed on the frame tube of the trolley, it will be because of two pieces. The plates cannot be overlapped and stretched and contracted. Therefore, most of the plates of the load-bearing surface of the trolley are made into a folding type to increase the length of the load-bearing surf...

AI Technical Summary

Problems solved by technology

However, it is generally known that most of the trolleys only have a fixed-sized bearing surface, and they cannot be transported for larger-sized goods, causing troubles in use

[0003] Therefore, there are also trolleys on the market that can adjust the size of the bearing surface, and this type of trolley can only be stretched by the frame tube, and if it is necessary to install plates on the frame tube of the trolley, it will be due to two pieces. The plates cannot be stacked and stretched and condensed. Therefore, most of the plates on the load-bearing surface of the trolley are folded to lengthen the length of the load-bearing surface and achieve the effect of strengthening the load-bearing surface. When in use, it is easy to cause problems such as pushing effort and unevenness due to the unstable center of gravity, which causes inconvenience in use, and needs to be improved.
