Three-wheel-assembly luggage barrow

Abstract

The invention provides a three-wheel-assembly luggage barrow, and belongs to the technical field of transportation equipment. The three-wheel-assembly luggage barrow comprises a barrow frame, a bearing plate, trundles and a telescopic pipe assembly; the foldable bearing plate and the telescopic pipe assembly are mounted on the barrow frame; the trundles are arranged at the bottom of the barrow frame, the trundles are three-wheel-assembly trundles, each trundle comprises a triangular trundle support, a movable wheel shaft in the middle of the trundle support and wheels respectively arranged atthree corners of the trundle support, and the three-wheel-assembly trundles are arranged at the bottom of the barrow frame in a movable and foldable mode through the trundle supports. The trundles arethree-wheel-assembly trundles, the movable wheel shaft is arranged in the middle of each trundle support, the wheels are installed at the three corners of the trundle support respectively, and climbing can be achieved by converting the three wheels on the three-wheel-assembly trundle through the movable wheel shaft during ladder carrying; in addition, the contact area between the trundle and theground in the carrying process can be increased, more labor is saved in the carrying process, the stability of the trundle is improved, and the trundle has the advantages of being convenient to use, wider in application range and more labor-saving in carrying.

Description

Technical field [0001] The invention relates to the technical field of transport equipment for transport, in particular to a luggage cart. Background technique [0002] Usually in airports, stations, traveling or shopping, etc., when heavy or more items and luggage need to be moved, they usually use trolleys, luggage carts and other handling tools to carry them, which is more convenient and labor-saving; and with moving equipment In order to gain consumers’ preference, the structure of luggage carts is becoming more and more simple and practical, and the design is more novel and beautiful. [0003] At present, the casters of luggage handling carts on the market are all single wheels, and the force area during the handling process is relatively small. Porters need to provide greater pulling or thrust to carry heavy objects, and the stability of the wheel Poor, you need to hold the luggage cart at all times, not to mention the stairs. When encountering the stairs, you can only carry...

AI Technical Summary

Problems solved by technology

However, due to the lack of structural design, the luggage carts currently on the market can be folded and shrunk in a variety of ways, and the difficulty of operation is also different. It is difficult to shrink, or it is easy to loosen and become unstable after long-term folding and shrinking

[0005] In addition, the casters of most luggage carts on the market cannot be folded, which still takes up space after being folded, making it inconvenient to store; It takes multiple steps to fold and shrink the load plate and casters, and it cannot be done in one step, which makes the folding work more cumbersome and time-consuming to operate, which does not meet the requirements of modern, convenient and fast pace of life
