The stretchable type trolley comprises a bearing plate, a telescopic plate, guide bodies, guide blocks, sliding grooves, a pull rod, a handle, a pull rod groove, a first handle groove, a second handle groove, universal wheels and a push handle. The bearing plate is connected with the telescopic plate by the two guide bodies, and the left ends ofthe guide bodies are fixed to the right side surface of the telescopic plate. The two sliding grooves are rectangular grooves on the top surface of the bearing plate, and the inner portions of the sliding grooves are slidably connected with the guide blocks. The guide bodies are slidably connected with the guide blocks through through holes penetrating through the left side surfaces of the slidinggrooves and the left side surface of the bearing plate. The bottom of the pull rod is hinged to the middle portion of the left end of the telescopic plate, and the handle is fixed to the top of the pull rod. The pull rod groove is located in grooves of the bearing plate and the telescopic plate, and the first handle groove and the second handle groove perpendicularly communicate with the pull rodgroove. The six universal wheels are separately fixed to the bottom portions of the bearing plate and the telescopic plate, and the push handle is connected with the right end of the top surface of the bearing plate by bolts. The stretchable type trolley is simple in structure, sweeping boards are retractable, and the handle and the push handle are convenient for two people to push and pull.

Description

technical field [0001] The invention relates to the technical field of small transportation tools, in particular to a stretchable trolley. Background technique [0002] Flat trolley is a kind of flat transportation equipment; it is convenient and practical to work in a small area. A moving vehicle that is pushed and pulled by manpower. Although material handling technology continues to develop, hand carts are still used today as an indispensable tool for handling. Trolleys are widely used in production and life because of their low cost, simple maintenance, convenient operation, and light weight. They can work in places where motor vehicles are inconvenient, and they are very convenient when transporting lighter items in a short distance. [0003] However, the size of the trolley is different. When transporting a lot of materials, there may be cases where it cannot be loaded. Therefore, it is necessary to increase the number of transportation. However, the general trolley ...

Problems solved by technology

[0003] However, the size of the trolley is different. When transporting a lot of materials, there may be cases where it cannot be loaded. Therefore, it is necessary to increase the number of transportation. However, the general trolley is pushed and pulled by one person on one side of the body, and it will be pulled when transporting heavier goods. In the case of no movement and less loading, a trolley that can change the loading size of the body and can be pushed and pulled by multiple people is needed
