Description

Technical Field

[0001] The utility model relates to the technical field of transport trolleys, in particular to a portable transport trolley. Background Art

[0002] A transport trolley usually refers to a vehicle or tool used to transport goods or items. These trolleys can be of various designs and forms to meet different transportation needs. An L-frame usually refers to a support structure of a specific shape. When transporting an L-frame, a transport trolley is usually required to transport the L-frame, making it more convenient to transport.

[0003] For some existing transport trolleys, when the roller is damaged and needs to be replaced, it is necessary to first turn multiple bolts to release the fixation between the roller and the connecting plate, and then remove the roller, which is rather troublesome. In addition, when carrying such transport trolleys, it is necessary to carry the straight rod to move the trolley, which is rather troublesome and results in poor portability.

[0004] Therefore, those skilled in the art provide a portable transport trolley to solve the problems raised in the above background technology. Utility Model Content

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a portable transport trolley, which can pull the hand-pulled plate forward to drive the two first blocks on the surface of the hand-pulled plate to leave the inner walls of the two sliders, thereby releasing the fixation of the two sliders. At this time, the two sliders are pulled to the opposite side, and the two sliders leave the inner walls of the two rollers, thereby releasing the fixation of the two rollers. At this time, the two rollers can be removed from the two sliding grooves. By setting a moving mechanism, it is not necessary to turn multiple bolts when replacing the rollers, which is more convenient.

[0023] 2. The utility model provides a portable transport trolley. By rotating the first bolt, the second bolt and the third bolt, the first slide plate and the second slide plate are slid to the bottom, and then the second rotating plate is rotated to turn the second rotating plate into the inside of the first slide plate. Finally, the hand-pull plate is pulled forward for a distance while the first rotating plate is rotated to turn it into the inside of the accommodating groove. After it is put in place, the hand-pull plate is released, and the second block on the surface of the hand-pull plate re-enters the inner wall of the first rotating plate, thereby fixing the folding mechanism in the accommodating groove.
