Embodiment Construction

[0030] The present embodiment will be further described below in conjunction with the accompanying drawings.

[0031] Such as Figure 1 to Figure 7 As shown, the lock head of this embodiment includes a lock cylinder assembly 2 , a clutch 3 , and a lock head body 4 .

[0032] Clutch 3 is pinned to the afterbody of lock core assembly 2 by clutch positioning pin 5, and it can only radially freely rotate relative to lock core assembly 2, and lock core assembly 2 is pinned in the lock head body 4 by lock core positioning pin 6. The lock body 4 is provided with a lock cylinder positioning hole 42 .

[0033] The lock core assembly 2 includes a lock core 20, a clutch plate 22, a return spring 23, a bead sealing plate 25, a sealing plate 26, a clutch plate spring 27, and a blocking element. The blocking element can be a marble or a vane, etc., and its cross-sectional shape can be set as a circle, a square, a rhombus, or a polygon, etc. as required. In this embodiment, the blocking e...

Abstract

The invention relates to an idle lock head clutch structure, which comprises a lock head body, a lock cylinder assembly arranged in the lock head body, and a clutch arranged opposite to the lock cylinder assembly, wherein the lock cylinder assembly comprises a lock cylinder, a clutch disc arranged in the lock cylinder and a stop element arranged in the lock cylinder; the clutch is sleeved with the lock cylinder; and the clutch disc is provided with a first clutch wall matched with the stop element and a second clutch wall matched with the clutch. The clutch of the lock cylinder is sleeved with the lock cylinder, and the clutch disc is provided with the first clutch wall and the second clutch wall matched with the stop element and the clutch respectively, so that clutch operation is realized, and in the novel clutch structure, the rear clutch is not driven to rotate by random angle ration of an unauthorized key, and the clutch can be driven to rotate by random angle insertion of an authorized key.

Description

【Technical field】 [0001] The invention relates to a lock head structure, in particular to a clutch structure of an idle lock head. 【Background technique】 [0002] At present, there are two main types of idling lock cylinder clutch structures on the market: one is a lock head with a sleeve-in-sleeve structure, and an intermediate clutch sleeve is arranged between the lock core and the lock head body. This type of lock head has a relatively large diameter and is not suitable for indoor door lock products. [0003] The other is the front and rear lock cylinder structure---the lock cylinder is divided into front and rear lock cylinders, and the middle is connected by a clutch. This type of lock head is relatively long in length and has a complicated mechanism, so the applicable occasions are very limited. 【Content of invention】 [0004] Based on this, it is necessary to provide a idling lock head clutch structure with smaller diameter and shorter length. [0005] An idling ...
