Description

Stroller with folding ramp

technical field

A trolley with a folding slope belongs to the field of trolley equipment, and specifically relates to a trolley matched with a washing machine for transporting and transferring articles, or carrying cages.

Background technique

The carts that are commonly used now usually need to be transported when transferring items to the cart and unloading the items on the cart. The transfer process of the items is not smooth and easy to cause damage to the items, and it is time-consuming and laborious. It is especially inconvenient when handling items, and usually requires several people to operate together.

Traditional cage trolleys are mainly flatbed carts. Lifting heavy cages onto the flatbed cart requires multiple people to operate, and most of the animals in the cages are aggressive. If they are frightened during the handling process, they will attack the operator, which poses a certain safety hazard. . If the cage is pushed directly, the dirt on the cage will fall to the ground, which not only increases the workload of the cleaner, but also affects the environment of the working area. Inconvenient to use.

Contents of the invention

The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art, and provide a cart with a folding slope which is convenient for transferring articles and saves labor.

When pushing the trolley, the spring fixes the positioning rod on the vertically upward left end of the card slot; when turning the slope guide rail, press down the positioning rod, compress the spring, and turn the handle to a suitable position. the slope.

The rollers are mounted on the lower part of the chassis through a height adjustment assembly. The height of each roller is adjustable, and the four corners of the chassis can be adjusted so that the cart can adapt to uneven roads. The chassis is always level, which is convenient for loading, unloading and transfer.

The rollers include two directional wheels mounted on the front end of the chassis and two universal wheels at the rear end. The universal wheel is fixed on one side of the handle, and the direction can be adjusted through the handle and the universal wheel, which is convenient to use.

Both ends of the slope guide rail are chamfered. The slope guide rail can be smoothly connected with the chassis, so that items can slide onto the chassis along the slope guide rail.

A flat plate is fixed on the upper part of the chassis, and two flat guide rails corresponding to the slope guide rails are fixed on the flat plate. The items to be transported are placed on the guide rails of the flat plate to reduce the friction with the flat plate and facilitate the transfer of the items.

The front end of the chassis is fixed with an L-shaped positioning plate whose upper part is horizontally bent, and a buffer block is fixed below the horizontal part of the positioning plate. When the side door of the washing machine is opened, the front end of the chassis extends into the washing machine, and the buffer block is positioned in contact with the washing machine to realize the seamless connection between the washing machine and the chassis, which is convenient for transferring items.

Compared with the prior art, the utility model has the beneficial effects of the pushcart with folding slopes as follows:

1. It is convenient and labor-saving to transfer items, directly push the items to be transported to the chassis along the slope guide rail, or push them from the chassis to the storage area of the items to be transported, which is convenient and labor-saving, and avoid manually lifting the items to be transported to the chassis of the trolley. Disadvantages such as the need for multiple people to operate items with large weight and volume.

2. The distance between the slope guide rails is adjustable, which can adapt to different sizes of items to be transported.

3. Use the spring to fix the positioning rod in the card slot to realize automatic positioning.

4. The height of the rollers is adjustable, so that the cart can adapt to the uneven road surface, and the chassis is always level, which is convenient for loading, unloading and transferring.

5. The universal wheel is fixed on one side of the handle, and the direction can be adjusted through the handle and the universal wheel, which is convenient to use.

6. The slope guide rail is smoothly connected with the flat guide rail, which is convenient for the transfer of items and prevents the end of the guide rail from hindering the sliding of the items. The flat guide rail prevents the items from being placed directly on the flat plate to cause high friction and difficulty in moving.
