Description

Technical Field

[0001] The utility model belongs to the technical field of carts, and in particular relates to an anti-collision and shock-absorbing cart. Background Art

[0002] A handcart is a transport vehicle that is pushed and pulled by manpower. Although the material handling technology of handcarts is constantly developing, handcarts are still used as an indispensable transport tool. Handcarts are widely used in production and life because they are low in cost, simple in maintenance, easy to operate, and light in weight. They can work in places where motor vehicles are inconvenient to use. They are very convenient for transporting lighter items over short distances. After searching, the application number "CN202122930612.9" discloses "an anti-collision handcart", which records: "The anti-collision handcart has a hand-slip phenomenon when pushing the handcart through the anti-slip sleeve, and the tires facilitate the movement of the handcart, and the anti-collision plate blocks external force impact. The anti-collision plate is in a U shape, which can expand the impact area, reduce the impact force per unit area, and improve safety. The anti-collision plate and the movable rod drive the movable block to move in the shock-absorbing hole and then compress the spring to buffer the impact force received. The movement of the anti-collision plate causes the sliding sleeve to slide on the surface of the sliding rod and then drives the connecting rod to rotate, so as to buffer the impact force received again and absorb energy. The tire facilitates the movement of the trolley by making use of the hand slip phenomenon when pushing the trolley through the anti-slip sleeve, and blocks the impact of external force through the anti-collision plate. The U shape of the anti-collision plate can indeed expand the impact area, reduce the impact force per unit area, and improve safety. However, the above comparative documents still have the following problems in actual use:

[0003] In actual use, the poor cushioning effect causes the items on the cart or the cart itself to be easily damaged, and it has fewer functions, making subsequent use more troublesome.

[0004] Based on this, it is extremely practical to provide a stroller that can achieve good buffering effect and has more functions. Utility Model Content
