Horseshoe lock head

Abstract

The invention discloses a horseshoe lock head. A lock cylinder, a main lock brake and a rotating shaft are axially locked from one end to the other end and positioned in a lock cylinder shell in a rotatable set angle in the circumference direction; the other end of the lock cylinder is fixed with the main lock brake; one end of the rotating shaft is provided with an eccentric rotating handle, theeccentric rotating handle jacks the step surface on the circumferential outer side of the main lock brake, the other end of the rotating shaft is fixed with one end of a torsion spring, and the otherend of the torsion spring jacks the radial inner wall of the lock cylinder shell; the outside wall far from the step surface of the main lock brake in the radial direction of the lock cylinder shell is an arc surface and provided with a first opening; and one side of the main lock brake far from the step surface can just extend out of the first opening and enter an arc groove on the outside wall of the lock cylinder shell. The main lock brake and a first secondary lock brake safely and effectively lock a lock ring, a horseshoe lock is prevented from being opened by vibration, meanwhile, the first secondary lock brake delays the opening of the main lock brake and also effectively prevents the main lock brake from being damaged and opened, and the horseshoe lock head is also provided with asecond secondary lock brake and a pin used together so as to further improve the safety factor of the lock.

Description

technical field [0001] The invention relates to a lock head, in particular to a horseshoe lock head. Background technique [0002] The traditional horseshoe lock core adopts spring as power, and the spring pushes the lock gate to lock the lock ring in the horseshoe lock, so that the lock ring cooperates with the lock gate to lock the horseshoe lock ring. This locking structure is easy to be shaken after the lock is locked. Open, and there is only one lock ring to lock the lock ring, so that the lock is easy to be opened destructively, and the safety factor is low, which is not safe enough. Contents of the invention [0003] In order to make up for the above shortcomings, the present invention provides a horseshoe lock head, the horseshoe lock head will not be opened by vibration, it is difficult to be opened destructively, and it is safer to use. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a horseshoe lock h...
