Trolley capable of shifting between turning and orientated straight driving

Abstract

The invention belongs to the field of cargo transportation equipment, and particularly relates to a trolley capable of shifting between turning and orientated straight driving. The trolley comprises a trolley body, wherein a plurality of universal wheels and a plurality of baffle plates are arranged on two sides of the trolley body; the baffle plates correspond to the universal wheels one to one; the plate surface of one end of a moving track of each baffle plate is adhered to the side surface of each universal wheel; a plate body at the other end of the moving track of each baffle plate is positioned outside the rotation track of each universal wheel. The trolley has the beneficial effects that the good direction control effect is good in a straight driving state, the time is shortened, the labor is saved, the security is high, the straight driving and turning state shifting effect is good, the limiting control effect of tooth matching is good, the small-angle turning effect is good, and the adjusting capability is good; moving plates are convenient to push and move, and the limiting fixation effect is good; connecting parts are fixedly connected with one same end of each of two moving plates, then the moving plates can be conveniently stressed to push and move simultaneously, thus being convenient to operate; a light reflecting lamp has an alarm function, thus being high in security; due to the chamfering beta, the universal wheels can be smoothly rotated and effectively adhered to the baffle plates when the moving plates are pushed, no resistance can be generated, and convenience in operation can be achieved.

Description

technical field [0001] The invention belongs to the field of cargo transportation equipment, and in particular relates to a small trolley capable of switching between turning and directional straight travel. Background technique [0002] In the production of industrial and mining enterprises, and even in daily life, trolleys are often used. The bottom of the trolley is provided with a plurality of wheels, generally four, and two wheels are provided on each side. In actual life and production, there are small carts with the rear two wheels as universal wheels, those with the front two wheels as universal wheels, and even those with four wheels as universal wheels. [0003] Regardless of the above-mentioned small carts, in the actual push-pull process, the direction will be due to factors such as terrain, ground roughness, and inaccurate positioning of the assembled four wheels, which will cause the universal wheels to rotate when the small cart is going straight, causing the ...

Problems solved by technology

[0003] No matter which kind of trolley is mentioned above, in the actual push and pull process, the direction will be due to factors such as terrain, ground roughness, and inaccurate alignment of the assembled four wheels, which will cause the universal wheels of the trolley to rotate when going straight, causing the car body to deviate left and right. When moving obliquely, it is necessary to adjust the direction and go straight again, which is time-consuming and labor-intensive; especially in the case of heavy cargo, it is particularly serious, the direction is not easy to control, and even causes accidents of hitting objects on both sides and operators
