Abstract

The utility model relates to a concealed theftproof lock, comprising a lock body (1), a lock sleeve (6), a lock core (5), and a lock tongue (8) which is coupled with the lock core (5). The concealed theftproof lock is characterized in that a keyhole (51) for unlocking the lock is arranged on the lock sleeve (6), and a rotary disc (2) with a handle (4) is rotated and sheathed with the lock body (1). The rotary disc (2) is provided with a key gap (21) corresponding to the keyhole (51), and the rotary disc (2) is connected with the lock core (5) in the form of the transmission; the transmission gap makes enough the rotary disc (2) rotate to the definite angle, and then, the key gap (21) deviates from the keyhole (51); the end part of the key is sheltered by the rotary disc (2). The utility model is a concealed theftproof lock having simple structure and high theftproof property.

Description

Hidden anti-theft lock

Technical field

The utility model relates to a kind of lockset, particularly relates to a kind of hidden anti-theft lock.

Background technology

Common spring lock (containing other many row's cylinder locks) when opening owing to outside the lock pellet shot from a slingshot is exposed to fully, is easy to quilt cover and opens.Modern society presses for better, the inexpensive again novel lockset of safety and reliability of theftproof performance.Though electronic cipher lockset and IC-card lockset security performance height thereof, but because the integrity problem of electronic device, still need a standby mechanical lock opened, Gao Dang electric lockset also is difficult to avoid one " weakness " so again, solving the antitheft of lock, is the major issue that ensures social family's property safety.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, hidden anti-theft lock that theftproof performance is high.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hidden anti-theft lock, include lock body, lock tube, lock core and the dead bolt that links with lock core, it is characterized in that: the keyhole that is used to unblank is located at described lock tube, the dial rotation that has handle is sleeved on the described lock body, on described rotating disk, be provided with the key breach corresponding with described keyhole, its key breach departed from described keyhole after described rotating disk was enough to make described dial rotation certain angle with described lock core driving coupling and its drive gap, and described rotating disk can cover in described key end.

Described rotating disk and described lock core driving coupling form are to be provided with the bar v notch v at described lock core front end, in described v notch v, be provided with strip piece, be provided with the hole clipping with the corresponding transmission of described strip piece on described rotating disk, its key breach departed from described keyhole after its drive gap was enough to make described dial rotation certain angle.

Described rotating disk and described lock core driving coupling form are to be provided with the bar shaped boss at described lock core front end, be provided with the draw-in groove with the corresponding transmission of described bar shaped boss on described rotating disk, its key breach departed from described keyhole after its drive gap was enough to make described dial rotation certain angle.

Described key is a trisquare shape, the cross section bar shaped of the keyhole corresponding with it.

The preceding end section of described key is a barb-type, and the cross section of the keyhole corresponding with it also is a barb-type.

Lockset key of the present utility model is inserted in the fixedly key on the lock tube, opens by rotary turnplate, and its lock core is hidden in the rotating disk, relies on draw-in groove in the rotating disk to drive lock core and rotates.Keyhole is sheltered from by rotating disk in opening process, makes this product have high anti-theft capability.Owing to the just corresponding bar shaped boss that drives lock core of draw-in groove when the rotation rotating disk covers lockhole is opened lockset, the thief wants the rotational lock core searching to unblank a little when the cover of trying is unblanked core, and rotating disk has sheltered from lockhole, can't set about at all.This lockset adopts indirect mode promptly to open lock by rotary turnplate, and the lock pellet shot from a slingshot is hidden in the rotating disk in opening process, thereby can avoid quilt cover to open fully.Because it still belongs to mechanical cylinder lock, thus anti-strong jamming, anti-strong magnetic destruction had, no circuit, power supply hidden danger, simple in structure, safe and reliable, and inexpensive.

In sum, the utility model is a kind of simple in structure, hidden anti-theft lock that theftproof performance is high.

The specific embodiment

Referring to Fig. 1 and Fig. 3, the keyhole 51 that is used to unblank is located at lock tube 6, rotating disk 2 turning sets that have handle 4 are contained on the lock body 1, on rotating disk 2, be provided with the key breach 21 corresponding with keyhole 51, be provided with bar v notch v 54 with lock core 5 front ends of dead bolt 8 interlocks, in described v notch v 54, be provided with strip piece 81, be provided with the hole clipping 31 with described strip piece 81 corresponding transmissions on described rotating disk 2, its drive gap is enough to make described rotating disk 2 its key breach 21 of back that turns an angle to depart from described keyhole 51.

Referring to Fig. 2 and Fig. 3, the keyhole 51 that is used to unblank is located at lock tube 6, rotating disk 2 turning sets that have handle 4 are contained on the lock body 1, on rotating disk 2, be provided with the key breach 21 corresponding with keyhole 51, be provided with bar shaped boss 52 with lock core 5 front ends of dead bolt 8 interlocks, be provided with the draw-in groove 3 with the 52 corresponding transmissions of bar shaped boss on rotating disk 2, the drive gap of bar shaped boss 52 and draw-in groove 3 is enough to make rotating disk 2 its key breach 21 of back that turns an angle to depart from keyhole 51, and rotating disk 2 can cover in key end.

Referring to Fig. 1 and Fig. 2, key 7 can be trisquare shape, the cross section bar shaped of the keyhole 51 corresponding with it.

Referring to Fig. 6 and Fig. 1, the preceding end section of key 71 also can be barb-type, and the cross section of the keyhole 53 corresponding with it also is a barb-type.The lockset of this structure, rotating disk 2 is littler with lock core 5 gaps, and structure is compact more.

Key 7 is inserted in the keyhole 51 on the lock tube 6, opens by rotary turnplate 2, and its lock core 5 is hidden in the rotating disk 2, relies on draw-in grooves 3 in the rotating disk 2 to drive lock cores 5 and rotates.Keyhole 51 is sheltered from by rotating disk 2 in opening process, makes this product have high anti-theft capability.

Referring to Fig. 4 and Fig. 5, because the just corresponding bar shaped boss 52 that drives lock core 5 of draw-in groove 3 is opened lockset when rotation rotating disk 2 covers keyhole 51 and key 7, the thief wants rotational lock core 5 searchings to unblank a little when the cover of trying is unblanked core 5, and rotating disk 2 has sheltered from keyhole 51, can't set about at all.

This lockset adopts indirect mode promptly to open lock by rotary turnplate, and the lock pellet shot from a slingshot is hidden in the rotating disk in opening process, thereby can avoid quilt cover to open fully.Because it still belongs to mechanical cylinder lock, so have anti-strong jamming, anti-strong magnetic destruction, no circuit, power supply hidden danger have solved traditional cylinder lock set easily by the technical barrier of pirate of the open, and is simple in structure, safe and reliable, and inexpensive.
