Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described in detail and completely with reference to the accompanying drawings. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Example one

Referring to fig. 1 and 4, the present embodiment provides a gear-type axle-adjustable transportation cart, which includes a frame 100 and an axle 200;

referring to fig. 2 and 4, the frame 100 has a carrying surface 101 for carrying goods and a mounting surface 103 for mounting the axle 200, which are oppositely disposed; the mounting surface 103 is provided with a rack 110;

the axle 200 includes a shaft body 210 and at least two rollers 230, the rollers 230 being rotatably mounted on the shaft body 210; the shaft 210 is slidably connected to the frame 100, and the shaft 210 is further provided with a gear 250 engaged with the rack 110.

Through the matching of the gear 250 and the rack 110, the axle 200 can translate relative to the frame 100, so that the axle center of the frame 100 during rotation is changed, the force arm of the worker rotating the frame 100 is adjusted, and the working strength of the worker is reduced.

Referring to fig. 4 and 6, if the shaft 210 is directly connected to the frame 100, it is difficult to achieve both the rotatable connection and the translational connection, and therefore, in the present embodiment, the axle 200 includes a slide plate 270, and the slide plate 270 is slidably disposed on the mounting surface 103 of the frame 100; the axle is rotatably connected to the sled 270.

In the embodiment, because the two subsequent gears 250 are disposed at the two ends of the frame 100 to clamp the frame 100, the gear 250 can prevent the sliding of the sliding plate 270 laterally, so that there is no need to additionally provide a sliding track form to prevent the sliding plate 270 from being displaced to the two sides of the frame 100.

In order to realize the rotatable connection between the axle 200 and the sliding plate 270, a plurality of hanging rings 271 arranged in parallel are arranged on one surface of the sliding plate 270 away from the frame 100; the axle 200 passes through the suspension ring 271.

In this embodiment, the frame 100 includes oppositely disposed first and

second sides

105, 107;

the first side 105 and the second side 107 are each provided with a rack 110; the shaft body 210 is provided with two gears 250, and the two gears 250 are respectively engaged with the corresponding racks 110.

The rack 110 is arranged by the pair of gears 250, so that the stability is improved, and on the other hand, the width of the two racks 110 is designed to be equal to that of the gears 250, so that the sliding plate 270 (the axle 200) can be prevented from sliding laterally relative to the frame 100 by the two gears 250 clamping the sliding plate 270 and the two ends of the frame 100.

In this embodiment, the frame 100 further has a front end 102 and a rear end 104 opposite to each other at two ends of the rack 110;

the tail end 104 is provided with a stop 130 at the mounting surface 103 for stopping the cargo. Frame 100 is provided with a handlebar 150 at front end 102.

Through the gear type axle adjustable transport trolley provided by the invention, the axle 200 can translate relative to the frame 100, so that the axis of the frame 100 during rotation is changed to adjust the force arm of a worker for rotating the frame 100, the axle 200 can be controlled to a position close to the tail end 104 at each unloading, then the front end 102 is lifted, and the strength can be saved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
