Description
Technical Field
[0001] This utility model relates to the field of handcart technology, specifically a handcart with an effective stopping structure. Background Technology
[0002] A handcart is a simple transport tool that is pushed or pulled by human power. It typically consists of a body, wheels, handles, and a support structure. Its design aims to improve the efficiency of moving heavy objects by reducing friction through wheels. Depending on the intended use, handcarts vary considerably in materials, structure, and load-bearing capacity. Handcarts remain a core solution for short-distance transport of small goods and continue to play an important role in society.
[0003] The existing technology has the following shortcomings: Application number 201721662786.9 describes a handcart with an emergency braking function, comprising a handcart body consisting of a frame and a storage basket. The storage basket is mounted on the frame, and the frame has wheels at its bottom. A push handle is located on the frame behind the storage basket. The wheels consist of two front wheels and two rear wheels, with the two rear wheels mounted on the same axle. The two front wheels are independent roller structures, both using universal bearings. A braking device is provided on the axle of the rear wheels to brake the handcart body by engaging the rear wheel axle. The handcart body has a control component that controls the operation of the braking device, and the control component is connected to the braking device. Due to the adoption of the above technical solution, this utility model has an automatic braking effect, locking the handcart when no manual pushing is performed, thereby avoiding safety problems caused by human error.
[0004] The braking mechanisms used in the above-mentioned equipment are mainly power-off brakes and brake discs, both of which are friction-type brakes. During long-term use, they are prone to significant wear, gradually reducing friction and affecting braking performance. In addition, the loading structure of the trolley is relatively fixed in actual use, making it impossible to flexibly adapt to transport different types of goods. Utility Model Content
