Abstract

The invention discloses a cart, and belongs to the field of constructional engineering. According to the scheme, the cart is convenient to adjust the supporting position of the rear wheel so as to achieve the labor-saving effect. The cart comprises a hopper body, front wheels and rear wheels, the front wheels are arranged on the front portion of the bottom of the hopper body, and the rear wheels are arranged on the rear portion of the bottom of the hopper body. The rear wheel comprises a wheel shaft, rolling wheels are arranged at the two ends of the wheel shaft respectively, and at least two grooves are formed in the rear portion of the bottom of the hopper body; the grooves are formed in parallel at intervals in the front-back direction of the hopper body, and the wheel shafts can be switched in the grooves and achieve clamping fit. By arranging a plurality of corresponding groove structures and adjusting different grooves to be matched with the wheel shaft, the supporting position of the hopper main body can be adjusted by the rear wheel, then different grooves can be selected to be arranged for matching according to actual conditions, and the purpose of saving labor can be achieved.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a structure of a cart. Background technique [0002] The cart used for construction transportation is a kind of equipment that is convenient for people to transport objects during the construction process. Its appearance can be convenient for people to use. It is not only simple in structure, but also easy to operate. [0003] The existing construction carts have certain disadvantages in use: firstly, the support position of the rear wheels of the cart cannot be adjusted, so it is not convenient to adjust the support position of the rear wheels according to the actual situation, and thus the labor-saving effect cannot be achieved well; secondly, The unloading of the cart is inconvenient, which brings certain adverse effects to people's use process; finally, when the cart is not installed with a construction elevator or a low-rise structure, it is difficult to go upstairs. ...
