Threaded cross key locking mechanism

Abstract

The invention provides a threaded cross key locking mechanism for solving the problem that automobile parts are prone to rotating and loosing under the action of external force. The threaded cross keylocking mechanism mainly includes a fixed base, a rotating part and a cross key, an inner hole is formed in the fixed base, the rotating part is coaxially distributed inside the inner hole, the diameter of the inner hole of the fixed base is larger than the diameter of an outer circle of the rotating part, the rotating part is internally provided with an internal thread used for being connected with other parts, a first notch is formed in the inner surface of the base, a second notch is formed in the outer surface of the rotating part, the cross key is of a cruciform structure overally, and is mainly composed of a key body with a circular arc structure and a first boss and a second boss which are fixedly connected to the front end and the rear end of the key body, a key body gap is connected between an inner circle of the fixed base and the outer circle of the rotating part in a matched mode, and the first boss and the second boss are correspondingly connected with the first notch andthe second notch in a matched mode. According to the threaded cross key locking mechanism, the structure is simple, operation is easy, the locking strength is high, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to a threaded cross key locking mechanism. Background technique [0002] Common loosening problems of threaded locking parts, especially auto parts, are affected by vibration and other external forces for a long time. influences. Commonly used thread locks include double nuts, special-shaped threads, nut end teeth, lock washers, cotter pins, etc., which have problems such as small locking force, strong vibration, high cost, difficult processing, and the need for complete sets of equipment. Contents of the invention [0003] In order to solve the above problems, the invention provides a threaded cross key locking mechanism, the technical solution adopted is as follows: [0004] A threaded cross key locking mechanism, characterized in that it mainly includes a fixed base, a rotating part and a cross key, the fixed base is provided with an inner hole, the rotating part is coaxia...
