Description

a small cart

technical field

The utility model relates to a transportation tool, in particular to a small trolley used in factories.

Background technique

In the production process of the factory, it is often necessary to use a trolley to transport parts or products in the factory area. This kind of trolley generally includes a U-shaped car plate arranged horizontally, and the open end of the car plate faces forward. A directional wheel is set at the front end of the left and right sides of the car plate, an armrest frame is established at the rear side of the car plate, a handrail is established on the armrest frame, and a steering wheel is established at the lower end of the armrest frame. This kind of trolley is more convenient to push on the flat ground, but when it is promoted in the factory area, it sometimes encounters steps, but it is very laborious to push this kind of trolley up the steps.

China Patent Authorization Announcement No.: CN202449017U, Authorized Announcement Date: 2012.09.26, discloses a small trolley, especially a small trolley used for cargo transfer in factories, which belongs to the technical field of auxiliary production equipment manufacturing. The trolley includes a trolley base with wheels at the bottom and a push handle, and also includes a push handle joint fixed on the trolley base, and the push handle is detachably installed on the trolley base through the push handle joint. It is also very laborious to push this kind of trolley up the steps.

Utility model content

The problem to be solved by the utility model is that the trolley used in the factory of the prior art is more convenient to push on the flat ground, but it is very laborious to push it up the steps. The utility model provides a trolley which can be easily moved Push up the steps.

The purpose of this utility model is achieved through the following technical solutions. A kind of small trolley, including a U-shaped car board arranged horizontally, the U-shaped opening of the car board faces forward, the front ends of the left and right sides of the car board are respectively provided with directional wheels, the rear side of the car board is provided with an armrest frame, and the armrest frame Handrails are arranged on the top, and the lower end of the armrest frame is provided with a steering wheel. The steering wheel is a combination wheel, which includes first round shafts respectively fixed on the left and right sides of the car board, which are sleeved on the first round shaft and can be wound around the first round shaft. The shaft sleeve that the circular shaft rotates is evenly fixed with three connecting rods on the same circumference of the outer cylindrical surface of the shaft sleeve. With this scheme, when the trolley is pushed on the flat ground, two of the three runners on the left or right side of the cart are in contact with the flat ground and roll on the flat ground; The wheel leans against the step, so that the runner contacts the step surface and pushes the trolley. At this time, the bushing drives the three connecting rods and the three runners to rotate around the first circular axis, so that a step-up step is easily completed. action. The three wheels circulate like this, and the trolley is easily pushed up the steps step by step.

As a preference, the rear side of the vehicle board is fixedly connected with an upper flat board and a lower flat board arranged horizontally, and a rotating shaft is rotatably connected between the upper flat board and the lower flat board, and the lower end of the rotating shaft passes through the lower flat board. At the lower end of the rotating shaft, the armrest frame is fixedly connected to the rotating shaft between the upper flat plate and the lower flat plate. With this solution, the steering wheel can be turned conveniently to control the direction of the steering wheel.

Preferably, the lower plate is provided with through holes into which positioning pins can be inserted. When the trolley is parked on the slope, the trolley will generate a sliding force due to gravity, so that the trolley can slide down easily. With this scheme, the armrest is rotated at an angle of 90 degrees, the rotating shaft and the steering wheel are also rotated at an angle of 90 degrees, and then the positioning pin is inserted into the through hole of the plate, and the lower end of the positioning pin passes through the through hole and blocks the steering wheel, so that the steering wheel It cannot be turned, and the cart is locked and will not slide down.

The beneficial effects of the utility model are:

1. The trolley can be easily pushed up the steps;

2. The stroller will not slide down when parked on a slope.

Detailed ways

The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:

As shown in Figures 1 to 2, a small trolley includes a U-shaped car plate 9 arranged horizontally, the U-shaped opening of the car plate faces forward, and the front ends of the left and right sides of the car plate are respectively provided with square through holes. Orientation wheel 1 is arranged in the through hole, and orientation wheel 1 is a kind of combination wheel, and this combination wheel comprises the first round shaft 13 that is fixed in the square through hole, is sleeved on the first round shaft and can rotate around the first round shaft The shaft sleeve 15 is uniformly fixed with three connecting rods 14 on the same circumference of the outer cylindrical surface at both ends of the shaft sleeve, and the three connecting rods are evenly distributed at equal angles. A circular shaft 11, a runner 12 that can rotate around it is sleeved on the second circular shaft. The rear side of the car plate is provided with a rear side plate perpendicular to the car plate arranged horizontally, and the upper plate 4 and the lower plate 7 arranged horizontally are fixedly connected on the rear side plate, and the upper plate is positioned at the upper side of the rear side plate, and the lower plate Located on the lower side of the rear side plate, a rotating shaft 5 is rotatably connected between the upper plate and the lower plate, the lower end of the rotating shaft passes through the lower plate, the steering wheel 8 is arranged at the lower end of the rotating shaft, and the armrest frame 3 is fixedly connected between the upper plate and the lower plate. On the rotating shaft between, the armrest frame is provided with handrail 2, and the lower plate is provided with the circular through hole 6 that can insert positioning pin, and the upper end of positioning pin is provided with hook, hangs on the upper plate when not in use. the

The above descriptions are preferred specific implementation modes of the present utility model, and are not intended to limit the implementation scope of the present utility model. The utility model can also have other embodiments, as long as it does not deviate from the spirit of the utility model, no matter what kind of transformation in form all falls within the protection scope of the utility model.
