Abstract
The present invention discloses a lock head and its key for preventing mutual unlocking. The lock head comprises a lock pith, a stop pin is arranged at a key hole which is located at the back of a marble hole of the lock pith; the matched key with the lock head includes a key piece, a spigot is arranged at the front of the key piece which matches with the stop pin on the lock pith. Based on a marble lock, the present invention is provided with various combinations of the stop pin and the spigot, so as to prevent mutual unlocking. Based on different matches of the stop pin and the spigot and with combinations of marbles of the marble lock and the teeth of the key, the combinations are increased in duplications, evidently, the mutual unlocking rate is greatly reduced and the theft-proof performance of the locks is improved.
Description
Technical field
The invention belongs to mechanical lock, relate to a kind of tapered end and key thereof of anti mutual-opening.
Background technology
Existing tapered end and key thereof mainly are to realize preventing to open mutually by the various combination of tartar on lock core marble and the key spoon sheet.Because the marble amount that adopts is limited, the compound mode of pellet shot from a slingshot and key tooth flower is also limited, mutual opening rate is generally ten thousand/and, this situation can not satisfy the needs to lockset safety performance.Therefore, the mutual opening rate of reduction lock is significant for the safety that improves lockset as much as possible
Summary of the invention
The objective of the invention is at above-mentioned situation, a kind of tapered end and key thereof of anti mutual-opening is provided, this lock and key thereof can reduce mutual opening rate greatly, have better security performance.
The present invention seeks to realize like this:
The tapered end of anti mutual-opening comprises lock core, is positioned on the keyhole of rear end, pellet shot from a slingshot hole to be provided with fixing pin in lock core.
With the key that described tapered end matches, comprise a spoon sheet, have the seam that matches with lock core upper position-arresting pin at the front end of spoon sheet.
The principle of this lock core and key anti mutual-opening: owing to be provided with fixing pin in the lock core keyhole, have only and use the spoon sheet to be provided with key with the corresponding seam of this lock core fixing pin, key could be inserted into the position and open lock core, use common key, because of being subjected to stopping of fixing pin, key can't be inserted into the lock core normal position, therefore lock core can not be opened.
The fit system of seam can adopt multiple on lock core upper position-arresting pin and the key spoon sheet: as in the same side of lock core keyhole and key spoon sheet fixing pin and seam being set respectively; Both sides at lock core keyhole and key spoon sheet are provided with fixing pin and seam; Adopt the fixing pin and the corresponding seam of different sizes; Seam that the employing fixing pin and the degree of depth differ or the like.
The present invention is on the basis of existing cylinder lock and blade lock, by fixing pin and seam be set in lock core and key correspondence different cooperate to reach prevent to open mutually.Owing to can form different cooperations between fixing pin and the seam, add the combination with pellet shot from a slingshot with the tartar of key of existing cylinder lock, its compound mode is multiplied, and obviously mutual opening rate can be reduced greatly, has further improved the theftproof performance of locking.
Further specify technical solution of the present invention below in conjunction with accompanying drawing.

The specific embodiment
See Fig. 1 to Fig. 3, the tapered end of anti mutual-opening comprises lock core 1, is positioned on the side of keyhole 3 of 6 rear ends, pellet shot from a slingshot hole to be provided with fixing pin 2 in lock core 1.With the key that described tapered end matches, comprise spoon sheet 4, have the seam 5 that matches with lock core upper position-arresting pin 2 in front end one side of spoon sheet 4.
See Fig. 4, Fig. 5, the seam 5 on fixing pin 2 on the keyhole and the spoon sheet 4 is located at opposite side.
Above-mentioned scheme is that the seam on fixing pin on the lockhole and the spoon sheet is located at both sides respectively.Can also fixing pin and seam be set simultaneously in the both sides of lockhole and spoon sheet, extremely shown in Figure 8 as Fig. 6.Another kind of scheme is to change the size of fixing pin and their different combinations of depth formation of seam.
Tapered end of the present invention and key are fit to all cylinder locks that adopt key and blade lock.
Claims (2)
