Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawings and embodiments.

[0026] Such as Figure 1-9 As shown, the clutch type lock head includes a lock sleeve, a transmission mechanism, and a mobile coding mechanism.

[0027] A cylindrical space for accommodating a transmission mechanism and a mobile coding mechanism is arranged in the inner hole of the lock sleeve 1 .

[0028] The inner hole of the lock sleeve 1 is provided with a long groove 11 as a clutch groove, the upper part of the clutch pin can extend into the long groove 11, and the lower part of the clutch pin 3 is still in the inner sleeve 2 described below, so that it can be combined with the clutch pin The inner sleeve can be prevented from rotating.

[0029] A spring 12 can also be arranged in the long groove 11 , one end of the spring 12 is limited by the bottom end of the long groove 11 , and the other end is limited by the clutch pin 3 .

[0030] The transmis...

Abstract

The invention provides a clutch type lock head, which comprises a lock sleeve, a transmission mechanism and a movable coding mechanism, wherein a clutch groove is arranged in a lock sleeve hole; the transmission mechanism is arranged in the lock sleeve hole and comprises an inner sleeve and a clutch pin; the inner sleeve is connected with an operating system of the lock head; a through groove is arranged on the outer wall of the inner sleeve; the clutch pin is arranged in the through groove; the upper part of the clutch pin is connected with the lock sleeve, and the lower part of the clutch pin is connected with a lock core; the movable coding mechanism comprises the lock core, a coding component, a connecting pin and a return spring; the coding component comprises a plurality of coding pieces; each coding piece is respectively arranged in a corresponding groove in the lock core, can move in the groove and is returned by the return spring; a coding groove is arranged on the upper surface of each coding piece; the coding grooves on the plurality of coding pieces form a key groove; a key hole is arranged in the lock core; and a key is inserted into the key hole to enable each codingpiece to move to compress the return spring and enable the coding groove on each coding piece to form a straight groove capable of accommodating the head part of the connecting pin. The clutch type lock head has the advantage that the door locking or unlocking can be carried out in the clockwise or anticlockwise direction.

Description

technical field [0001] The invention relates to a lock head, in particular to a clutch type lock head. Background technique [0002] The existing clutch-type lock head disclosed by the applicant in Chinese patent documents CN104912386A and CN104912394A provides two major technologies: the astronomical key amount of the lock head and the 360-degree freely rotatable lock cylinder, which greatly improves the anti-lock technology. Opening ability and anti-non-technical opening ability. [0003] However, this clutch type lock head can only be rotated and decoded in a single direction, and the operating system in the drive lockset is opened (unlocked). Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a clutch-type lock head that can be operated clockwise or counterclockwise for the above-mentioned shortcomings of the prior art. [0005] The technical solution adopted by the present invention to solve the problems of t...
