Abstract

The invention discloses an idler wheel device. The idler wheel device comprises a mounting shaft, a mounting frame, a supporting wheel and a locking structure; a positioning assembly is mounted at thejunction of the mounting shaft and the supporting frame, and the positioning assembly comprises a fixing block fixedly mounted in the supporting frame, a directional sliding block, and an universal sliding block mounted between the directional sliding block and the lower surface of the top end of the supporting frame, wherein the directional sliding block is connected with the fixing block through a compression spring and arranged on the upper part of the fixing block; steel balls are mounted between the universal sliding block and the lower surface of the top end of the supporting frame, andthe universal sliding block is fixedly connected with the mounting shaft; and a protruding part and a groove which are mutually matched are formed between the directional sliding block and the universal sliding block, and after the protruding part and the groove are matched, the directional sliding block and the universal sliding block are circumferentially fixed. According to the idler wheel device, a vehicle body can be automatically adjusted to be in directional advancing or universal advancing through outside damping force, using is more convenient, meanwhile, the height of the vehicle body can further be adjusted, and the damping and buffering effects can be achieved.

Description

technical field [0001] The invention relates to a roller, in particular to a roller device capable of directional and universal travel and height adjustment. Background technique [0002] At present, casters are widely used in supermarket shopping carts, medical ambulances, furniture, mechanical equipment and other fields. The casters in the prior art mainly include the following three structures: the first is an ordinary wheel, the wheel can only roll forward, cannot rotate by itself, and does not have a brake mechanism; the second is a wheel with a brake mechanism, the wheel passes through the brake mechanism Locking; the third is the universal wheel with brake structure, which not only has the brake function, but also can turn flexibly. The running equipment with the casters of the above three structures can meet the function of walking on the ground, but when encountering obstacles, the casters of the first structure cannot adjust the direction in time, although the cas...
