A threaded cross key locking mechanism

Abstract

In order to solve the problem that auto parts are easy to rotate and loosen under the action of external force, the invention provides another threaded cross key locking mechanism, which mainly includes a fixed base, a rotating part and a cross key. The rotating part is coaxially distributed inside the inner hole, and the diameter of the inner hole of the fixed base is larger than the diameter of the outer circle of the rotating part. The rotating part is provided with an internal thread for connecting with other parts. The inner surface of the base There is a first notch on the upper surface, and a second notch is provided on the outer surface of the rotating part. The cross key has a cross-shaped structure as a whole, and is mainly composed of a key body in an arc-shaped structure and a second key body fixedly connected to the front and rear ends of the key body. It is composed of a boss and a second boss, and the key body is connected between the inner circle of the fixed base and the outer circle of the rotating part by clearance fit, and the first boss and the second boss are connected with the first notch and the second boss respectively. The two notches are matched and connected, and the device has the advantages of simple structure, easy operation, high locking strength and good effect.

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...
