Abstract

The utility model discloses an anti-inter unlocking lock and a key thereof, wherein the lock comprises a lock core and a key tablet, wherein a stop pin is arranged on a keyhole which is arranged on the rear end of a marble hole in the lock core, a key which is matched with the lock head, and a spigot which is matched with a stop pin on the lock core is opened on the front end of the key tablet. The utility model achieves to prevent mutually unlocking through that the stop pin and the spigot are differently matched on a corresponding position of the lock core and the key based on a prior night lock. Because the stop pin and the spigot are capable of being differently matched, further a marble of a prior night lock is matched with a bit of the key, the combination mode is exponentially increased, obviously, the radio of inter unlocking is capable of being reduced, and the theftproof performance of the lock is increased in one step.

Description

A kind of tapered end of anti mutual-opening and key thereof

Technical field

The utility model belongs to mechanical lock, relates 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

The utility model content

The purpose of this utility model is at above-mentioned situation, and a kind of tapered end and key thereof of anti mutual-opening is provided, and this lock and key thereof can reduce mutual opening rate greatly, have better security performance.

The utility model purpose is achieved in that

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 utility model 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 solutions of the utility model 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.

The utility model tapered end and key are fit to all cylinder locks that adopt key and blade lock.

Claims

1, a kind of tapered end of anti mutual-opening comprises lock core, it is characterized in that being positioned in lock core on the keyhole of rear end, pellet shot from a slingshot hole being provided with fixing pin.

2, the key that matches with the described tapered end of claim 1 comprises a spoon sheet, it is characterized in that having the seam that matches with lock core upper position-arresting pin at the front end of spoon sheet.
