Abstract
The utility model discloses an anti-pick lock mechanism which comprises a lock core, an outer shell and a transmission shaft wheel, wherein, a sleeve cylinder which moves axially in an inner cavity of the outer shell is arranged between the lock core and the outer shell, and a cam structure is arranged between the sleeve cylinder and the outer shell; the bottom of the sleeve cylinder is provided with an inclined concave part, and the outer shell is provided with an inclined cam which is positioned in the inclined concave part. When the utility model is operated abnormally by external force, the sleeve cylinder can move along the inner cavity of the outer shell axially, and the lock core is separated from the transmission shaft wheel; in such a case, no matter how the lock core is rotated, an opening member in a lock core mechanism can not be driven to open a lock set. When the sleeve cylinder is reset, the lock core restores normal functions, so that the utility model achieves the purpose that the functions of the lock mechanism is not damaged and the lock set can be opened normally, and thus the lock mechanism has safety and anti-pick performances.
Description
Affiliated technical field
The utility model relates to a kind of pick-proof and steals latch mechanism.
Background technology
The lock core mechanism of existing lockset does not possess pick-proof and steals device, after in a single day lock core mechanism is subjected to outside unconventional operation, tend to inner body is damaged and the disabler that makes lock core, cause the disabler of whole lockset, therefore, the function of the lock core mechanism of existing lockset is incomplete.
Summary of the invention
The purpose of this utility model is to overcome the incomplete problem of lock core body function of above-mentioned lockset, is subjected to also making the lock core body function recover normal pick-proof after the evil power operation and steals lock core mechanism even provide a kind of.
To achieve these goals, we adopt a kind of pick-proof to steal latch mechanism, comprise lock core, shell, the transmission arbor wheel being provided with a sleeve that axially moves in can the inner chamber at shell between lock core and the shell, is provided with cam structure: be provided with oblique recess on the cover tube bottom between sleeve and the shell, be provided with oblique cam on shell, tiltedly cam is positioned at oblique recess.
The beneficial effects of the utility model are, owing to increased a sleeve that can in the inner chamber of shell, axially move between lock core and the shell, between sleeve and shell, be provided with cam structure, after sleeve moves axially, the rotational lock core opening tool that all can't drive in the lock core mechanism removes to open lockset in any case, and after sleeve resets, latch mechanism recovers normal function, reach the latch mechanism function is not destroyed, can make the normal purpose of opening of lockset again, make latch mechanism have the safety pick-proof performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the partial schematic sectional view of an example of the present utility model.
1 is lock core among the figure, the 2nd, and sleeve, the 22nd, oblique recess on the cover tube bottom, the 3rd, shell, the 33rd, oblique cam on the shell, the 4th, transmission arbor wheel, the 5th, opening tool, the 6th, spring, the 7th, connector, the 8th, locking plate (or pellet shot from a slingshot).
The specific embodiment
The lock core 1 that locking plate 8 is housed inserts and is equipped with in the shell 3 of sleeve 2, transmission arbor wheel 4 is contained in the afterbody of lock core 1 and flexibly connects with opening tool 5, spring 6 is contained between transmission arbor wheel 4 and the opening tool 5, plays the effect that part resets, and connector 7 is done lock core 1 axially to be connected with opening tool 5.Be provided with cam structure between sleeve 2 and the shell 3: be provided with oblique recess 22 on sleeve 2 bottoms, be provided with oblique cam 33 on shell 3, tiltedly cam 33 is positioned at oblique recess 22.
When normal unlatching/locking lock core mechanism, lock core 1 drives transmission arbor wheel 4 and does to rotate synchronously, drives opening tools 5 by transmission arbor wheel 4 again and rotates and open/the locking lockset; This moment, sleeve 2 was fixed in the inner chamber of shell 3.
After lock core mechanism is subjected to the operation of improper twisting resistance and reaches a certain value (greater than 4Nm), under the effect of the oblique cam 33 of shell 3, sleeve 2 moves axially along the inner chamber of shell 3 to the right, and it is also mobile vertically together to drive transmission arbor wheel 4, transmission arbor wheel 4 is separated with lock core 1, and rotational lock core 1 in this case, and can't drive transmission arbor wheel 4, therefore can't open/the locking lockset, and not destroy lockset.
Designed symmetry on sleeve 2 and shell 3 two can make sleeve 2 make axially movable cam structure, so moving 180 ° of lock core 1 revolution, all can make moving axially that sleeve 2 does once to come and go.After sleeve 2 is returned to the home position, recover the normally function of unlatching/locking.
The utility model is rational in infrastructure, and is easily manufactured, is fit to the lock core mechanism of various automotive locks, also can be used for the lockset of civilian lockset and specific use.
Claims (2)
1, a kind of pick-proof is stolen latch mechanism, comprise lock core (1), shell (3), transmission arbor wheel (4), it is characterized in that between lock core (1) and shell (3), being provided with a sleeve (2) that can in the inner chamber of shell (3), axially move, be provided with cam structure between sleeve (2) and the shell (3): on sleeve (2) bottom, be provided with oblique recess (22), be provided with oblique cam (33) on shell (3), tiltedly cam (33) is positioned at oblique recess (22).
2, pick-proof according to claim 1 is stolen latch mechanism, its feature on shell (3) and sleeve (2), be provided with the symmetry two can make sleeve make axially movable cam structure.
