The utility model relates to an off-road trolley case which can help the case body go up and down stairs and pass through waterlogged roads by arranging a group of telescopic auxiliary pulleys on the case body. The fixed shaft is connected to the rear end of the bottom of the box, the left and right main pulleys are respectively connected to the left and right shaft heads of the fixed shaft, the lower ends of the left and right support arms are respectively connected to the left and right journals of the fixed shaft, and lock levers are arranged in the left and right support arms and the spring, the left and right ends of the control rod are respectively connected with the left and right locking rods, lock holes are opened on the left and right journals of the fixed shaft, the upper ends of the left and right supporting arms are respectively connected with the left and right journals of the moving shaft, and the left and right secondary pulleys are respectively connected On the left and right shaft heads of the moving shaft. In use, turn the left and right support arms outward 90 degrees, and when the lock rod and the lock hole lock the support arms, the box can go up and down stairs through the auxiliary pulley or pass through the water-logged road. When the left and right supporting arms and the left and right auxiliary pulleys are stored in the grooves on the back plate of the box body, the box body can slide through the main pulley.
Description
technical field [0001] The invention relates to a trolley case, in particular to an off-road trolley case which can help the case go up and down stairs and pass through waterlogged roads by arranging a group of telescopic auxiliary pulleys on the case body. Background technique [0002] At present, because the diameter of the pulley of the known trolley case is relatively small, it is inconvenient to go up and down the stairs and cannot pass through the waterlogged road surface. Contents of the invention [0003] In order to overcome the shortcomings of the existing trolley case that it is inconvenient to go up and down the stairs and cannot pass through the waterlogged road, the present invention provides a cross-country trolley case, which can be equipped with a set of telescopic auxiliary pulleys on the box body. , so as to help the box go up and down the stairs and through the water-logged road. [0004] The technical solution adopted by the present invention to solve...
