Wheel device capable of smoothly crossing obstacle

Abstract

The invention provides a wheel device capable of smoothly crossing an obstacle and belongs to the field of wheel equipment. The wheel device comprises rectangular pipes, springs, hinges, first hinge rivets, second hinge rivets, third hinge rivets, rectangular steel materials, square pipes, wheel supports, cylindrical pins and wheels, wherein the square pipes, the wheel supports, the cylindrical pins and the wheels jointly form universal wheels. The rectangular pipes are welded to the periphery of a working table. Each rectangular pipe and the corresponding rectangular steel material are fixed to two hinge bodies of the corresponding hinge. The pipes, the wheel supports, the cylindrical pins and the wheels jointly form the universal wheels and are fixed to the rectangular steel materials in a welded manner. One end of each rectangular steel material is fixed to the corresponding hinge, a small hole is punched in the other end of each rectangular steel material, one end of each spring is hung on the corresponding small hole, and the other end of each spring penetrates a square hole in the lower end of the rectangular pipe to be hung on a round hole in the upper end of the corresponding rectangular pipe. By the adoption of the wheel device, the elastic deformation of the springs and relative rotation of the hinges are used, so that the wheels are automatically lifted when encountering the obstacle, and therefore the wheel device can smoothly cross the obstacle.

Description

Technical field [0001] The invention relates to a wheel device capable of smoothly surmounting obstacles, in particular to a device that uses spring tension and elastic deformation to make wheels automatically and smoothly surmount obstacles, belonging to the field of wheel equipment. Background technique [0002] The wheel device is almost a must-have device for every movable device, and when these devices are moving, they will inevitably encounter thresholds or other small obstacles, especially when carrying some fragile and explosive items during the journey. , You need to be extra cautious and even need to carry the equipment together, and then continue to move, not only time-consuming and laborious, greatly slowing down the work efficiency. At present, there is no such device in the market to deal with this problem, but this device can just solve this problem. This device can be installed on a nursing bed or a trolley, so that the device can directly and steadily cross obsta...
