Description
Technical field
The utility model relates to a kind of lockset, the anti-lock of dialling of particularly a kind of pick-proof.
Background technology
At present, the kind of lockset is a lot, and all locksets are purpose to improve its safety all.The key position of lockset commonly used is a tapered end, its mainly by lock body, lock core and make lock body, lock core can not arbitrarily pellet shot from a slingshot, spring be formed in relative rotation, after the key corresponding with lock inserts lock core, by moving of pellet shot from a slingshot, lock core is rotated relative to lock body, move thereby drive dead bolt, lock is opened.But because the intensity of pellet shot from a slingshot is limited, high-intensity object is inserted in the lock core keyhole, apply certain revolving force, just pellet shot from a slingshot can be cut off, lock was lost efficacy.Another kind of situation is that present lockset is easy to be pushed aside.For this reason, people improve lockset, its objective is the security performance that improves lockset.
Summary of the invention
The purpose of this utility model is to overcome the defective that above-mentioned lockset is pried open easily or pushed aside, provides a kind of security performance good, is not easy the lockset of being pried open or being pushed aside.
For achieving the above object, the technical solution adopted in the utility model is: the anti-lock of dialling of a kind of pick-proof, comprise lock core, the lock body and the pellet shot from a slingshot that match with lock core, stage clip, it is characterized in that between lock core and lock body, being set with the tubulose connecting ring that can rotate relative to lock core and lock body, the locking mechanism of being made up of rack and pinion is installed in the tube wall of tubulose connecting ring, gear is installed between two tooth bars, and mesh with two tooth bars, one end of one of them tooth bar and the corresponding contact of the pellet shot from a slingshot on the lock core, the other end is equipped with stage clip, another tooth bar one end and the corresponding contact of the pellet shot from a slingshot on the lock body.
It is above-mentioned that to be installed in the quantity of the pellet shot from a slingshot locking mechanism of being made up of rack and pinion on the tubulose connecting ring identical with marble amount in the lock core.
Pellet shot from a slingshot and stage clip also are installed in the tube wall of above-mentioned tubulose connecting ring.
Characteristics of the present utility model are: 1, change the pellet shot from a slingshot of former lock, the locking mechanism that spring is formed into be made up of gear, tooth bar locking mechanism, between lock core and lock body, increased simultaneously the tubulose connecting ring, like this when unblanking, by two tooth bars relative to oppositely moving, make the pellet shot from a slingshot on the lock body move to lockset position of coupler,, drive the tubulose connecting ring and rotate by rotary locking cylinder, drive dead bolt by the tubulose connecting ring and move, thereby lock is opened.After the pellet shot from a slingshot between lock core and the tubulose connecting ring was cut off by external force, when lock core rotated, lock can't be opened like this, played to prevent in the external force effect pried open of rotation lock by force.2, drive the process that dead bolt is unblanked by lock core, become by tubulose connecting ring drive dead bolt and unblank.The variation of this structure can prevent effectively that lock from being pushed aside.When adopting illegal means that the pellet shot from a slingshot between lock core and the tubulose connecting ring is pushed the position that can make the lock core rotation, have only lock core to rotate, and dead bolt is motionless, lock can't be opened.And want illegally the pellet shot from a slingshot between tubulose connecting ring and the lock body to be pushed open position, can't realize from this structure.So, the technical program can effectively prevent with lock push aside may.
Description of drawings
Accompanying drawing 1 is the utility model embodiment 1 structural representation;
Accompanying drawing 2 is the local enlarged diagram of the utility model Fig. 1;
Accompanying drawing 3 is the structural representation of the utility model embodiment 2.
The specific embodiment
As shown in Figure 1, 2, between existing lock core 3 and lock body 1, be set with the tubulose connecting ring 2 that can rotate relative to lock core 3 and lock body 1, the locking mechanism of being made up of tooth bar 4,7 and gear 8 is installed in the tube wall of tubulose connecting ring 2.Be installed between upper gear rack 4 and the lower gear rack 7 at this locking mechanism middle gear 8, and with the engagement of above-mentioned two tooth bars, the wherein pellet shot from a slingshot 9 corresponding contacts on the left end of upper gear rack 4 and the lock core, the right-hand member of upper gear rack 4 is equipped with stage clip 5, the pellet shot from a slingshot 6 corresponding contacts on the right-hand member of lower gear rack 7 and the lock body.
As shown in Figure 2, when lockset was in locking states, the pellet shot from a slingshot 9 in the lock core 3 was between lock core and the tubulose connecting ring, and the lower gear rack 7 in the tubulose connecting ring 2 is between tubulose connecting ring and the lock body, and lock core just can't rotate relative to lock body with the tubulose connecting ring like this.In when design, the little intensity with lower gear rack 7 of the intensity of pellet shot from a slingshot 9, in picklock inserted key hole 10 in the lock core, under the effect of enough big turning moment, pellet shot from a slingshot 9 was cut off, and lock core rotates with respect to the tubulose connecting ring.During owing to unblank, be rotation, drive dead bolt and open and close, so the rotation of lock core can not be opened lock by the tubulose connecting ring.
As shown in Figure 3, when the key corresponding with this lock 11 inserts in the keyhole in the lock cores, pellet shot from a slingshot 9 is promoted to the right, drive upper gear rack 4 and move right, gear 8 clockwise rotates, and drives lower gear rack 7 and is moved to the left, under the effect of the stage clip of pellet shot from a slingshot 6 right-hand members, pellet shot from a slingshot 6 is moved to the left, and when moving to as shown in Figure 3 the position, moves and stops.At this moment key, lock core drives the tubulose connecting rings by pellet shot from a slingshot 9 and rotates, and the tubulose connecting ring drives dead bolt and moves, and lock is opened.
If want this lock is opened,, so just can't make tooth bar 7 be in unlocking condition shown in Figure 3 owing to dial the position that the instrument of lock can't arrive lower gear rack 7 by the mode of pushing aside.
The quantity of the locking mechanism of being made up of tooth bar 4,7 and gear 8 in the technical program can be provided with according to the concrete condition of lock.As the pellet shot from a slingshot in the lock core is single 4 row, and at this moment the quantity of above-mentioned locking mechanism is corresponding with the pellet shot from a slingshot in the lock core, also is 4 groups.Processing for convenience and installation can be made the tubulose connecting ring locking mechanism that tooth bar 4,7 and gear 8 all are installed in each becate that is combined into by 4 becates simultaneously.
When key shape was triangle, as shown in Figure 3, the locking mechanism system of gear external member was made up of tooth bar 4,7 and gear 8, and all the other are by the upper and lower two groups pseudo-devices that comprise that pellet shot from a slingshot 12, ball and stage clip 13 are formed, and so just can improve the safety of lockset.
