Hand-adjustable limiting device for a rotating lever of a pedal sleeve for preventing the pedal sleeve from being accidentally trampled and a use method thereof

Abstract

The invention discloses a hand-adjustable limiting device for a rotating rod of a pedal sleeve, which comprises a main board, a rotating rod, a sliding groove, a rotating shaft, a torsion spring, a limiting screw, a flexible rubber washer, an anti-skid nut and an elastic rubber ring. The device is characterized in that an opening is arranged in front of the main board, and a sleeve is arranged onthe side of the main board; the rotating rod is provided with a sliding groove; the rotating shaft serially connects the rotating rod and the sleeve together; the torsion spring is sleeved on the rotating shaft, one end of the torsion spring is abutted against the rotating lever, and the other end is abutted against the main board; under the action of the torsion spring, the rotating lever will always turn upward. The limit screw passes through the sliding groove, the metal washer and the flexible rubber washer, and is screwed into the anti-skid nut; The anti-skid nut is provided with a groove, and an elastic rubber ring is fixed in the groove. By adopting the rotation rod limiting structure of the invention, a user can adjust the limiting screw by hand.

Description

technical field [0001] The invention relates to a limit device for automobile driving safety equipment, in particular to a free-hand adjustable limit device for a rotating rod of a cover for preventing mistaken stepping on a pedal. Background technique [0002] The present inventor has designed a simple in structure, safe and reliable safety device installed on the brake accelerator pedal, but these devices are all troublesome when closing and opening the protective bar. The screwdriver and the clamping method need to be equipped with the screw limiting method. When the screw is over-tightened, it cannot be moved with bare hands; if it is over-tightened, the screw may become loose due to vibration until it slides and shifts by itself; and the spring washer is used for anti-slip because the anti-slip protruding part of the spring washer is easy to fall into the chute , so that the limit device is loose or stuck; therefore, when it is necessary to open or close the protection ...

[0002] The present inventor has designed a simple in structure, safe and reliable safety device installed on the brake accelerator pedal, but these devices are all troublesome when closing and opening the protective bar. The screwdriver and the clamping method need to be equipped with the screw limiting method. When the screw is over-tightened, it cannot be moved with bare hands; if it is over-tightened, the screw may become loose due to vibration until it slides and shifts by itself; and the spring washer is used for anti-slip because the anti-slip protruding part of the spring washer is easy to fall into the chute , so that the limit device is loose or stuck; therefore, when the protection bar needs to be opened or closed for different groups of people, it is necessary to design a more convenient and reliable limit structure
