[0004] In order to overcome the above-mentioned defects existing in the prior art, the utility model provides a retractable trolley.
[0005] The technical solution adopted by the utility model to solve its technical problems is: a retractable trolley, including a car plate, an activity plate is slidably installed left and right at the upper end of the car plate, a second mounting bracket is fixedly installed at the lower left end of the activity plate, an auxiliary wheel is movably installed at the lower end of the second mounting bracket, two groups of mounting holes are arranged on the outer side of the right end of the car plate, and a handlebar is slidably installed left and right in the mounting holes.
[0006] Further, a first mounting bracket is fixedly installed at the lower end of the car plate, and a wheel is movably installed on the first mounting bracket.
[0007] Further, two groups of chutes are arranged in parallel at the upper end of the car plate, two groups of sliders are fixedly installed at the lower end of the activity plate, and the sliders are slidably installed in cooperation with the chutes.
[0008] Further, two groups of first through holes are arranged on the activity plate, a first threaded hole is arranged at the bottom right side of the chute, and the first threaded hole and the first through hole are installed in cooperation with bolts.
[0009] Further, a second threaded hole is arranged at the bottom left side of the chute, and the second threaded hole is installed in cooperation with the first through hole.
[0010] Further, several groups of second through holes are arranged on the front and rear side walls of the car plate, a third threaded hole is arranged on the handlebar, and the third threaded hole and the second through hole are installed in cooperation with fastening bolts.
[0011] The beneficial effects of the present utility model are as follows: By loosening the bolt between the first threaded hole and the first through hole, then moving the movable plate to the left, then tightening the bolt through the cooperation of the first through hole and the second threaded hole, then moving the handlebar left and right according to the actual situation, and then tightening with the fastening bolt through the cooperation of the second through hole and the third threaded hole, the disassembly is relatively simple and it can be applied to different working conditions.
