Description

Pellet lock with connecting core

The utility model relates to lock, key, particularly pellet shot from a slingshot top lock.

The cylinder lock technology has been widely used in various locks, as door lock, padlock, in padlock, it has a rotatable lock core, utilize array spring and pellet shot from a slingshot to make the locking of lock core and lock body and can not rotate, when inserting in the keyhole with this phase-locked key that cooperates, each is organized and just can make this locking action releasing and lock core can be rotated after pellet shot from a slingshot produces displacement, thereby driving the dead bolt displacement by transmission mechanism can eject and rotate latch hook, promptly opened padlock, this padlock transmission mechanism is complicated, so top lock that has a kind of lock core and latch hook directly to link to each other now, after key inserts keyhole, the interface of the interface of pellet shot from a slingshot and lock core and lock body makes lock core move and to rotate in the same face of cylinder, at first key is upwards pushed away the hole that the other end that makes latch hook is deviate from lock body, and screw key can be opened lock again, this lock still can not avoid opening with master key the disadvantage of lock, simultaneously as the mounting that will seal each pellet shot from a slingshot take down and can take out pellet shot from a slingshot easily and lock is opened.

The purpose of this utility model provides a kind of difficult quilt and substitutes key and open, and takes off the higher pellet shot from a slingshot top lock with connection-core of safety that mounting can not take out pellet shot from a slingshot.

The purpose of this utility model realizes by following technical scheme, pellet shot from a slingshot top lockset with connection-core has lock body, latch hook, rotatable and mobile lock core in the hole of lock body, be positioned at the keyhole of lock core bottom, return spring, it is characterized in that said latch hook is fixed on the lock core, also have a connection-core that can in the hole of lock body, move and prevent the pin that connection-core rotates, connection-core top has and the opposite side of the latch hook pin of interlock mutually, the marble spring and the pellet shot from a slingshot that also have the blind hole that is arranged in connection-core, be arranged in the pellet shot from a slingshot of lock core length by the configuration of the corresponding tooth depth of key, in lock body and length equal the pellet shot from a slingshot of the lock body wall thickness between lock body upper lock core and the connection-core.When key inserts keyhole, the interface of pellet shot from a slingshot and the fitting face of lock core and lock body or connection-core and lock body are matched, upwards push away key, can make on the latch hook and move, screw key can make latch hook rotate and lock is opened again.

Now in conjunction with the accompanying drawings and embodiments the pellet shot from a slingshot top lock with connection-core of the present utility model is explained in detail.

Fig. 1 is the sectional view that the utlity model has the pellet shot from a slingshot top lock of connection-core;

Fig. 2 is the upward view that the utlity model has the pellet shot from a slingshot top lock of connection-core;

Fig. 3,4 be the latch hook end along A-A among Fig. 1 to partial sectional view.

As Fig. 1, pellet shot from a slingshot top lockset with connection-core has lock body 4, has the columniform lock core 6 that can in the hole, rotate and move in the hole of one end of lock body 4, the top of lock core 6 is connected with the B end of latch hook 1 mutually with steady pin 5, the length of steady pin 5 is greater than the diameter of lock core 6, it grows in the groove with certain depth that partly stretches on the lock body, make the spring 3 can be to lock body with the downward bullet of latch hook, a lid 2 is being fixed on the top in hole, be with return spring 3 on the latch hook 1 between lid 2 and the lock core 6, the center of lock core has keyhole 7 along the length direction of lock core, the other end at lock body 4 also has the hole, has columniform connection-core 13 in the hole, it also can move in the hole, a cylindrical connecting axle 15 is fixed with bearing pin 14 in the upper end of connection-core, pin 19 stretches in the groove of connection-core side to stop connection-core to rotate, connection-core and connecting axle also can be made into one, the top of connecting axle 15 is semicircle and is fixed with pin 16, the diameter of connecting axle 15 is identical with the diameter of latch hook 1, the D end of latch hook 1 also is semicircle, and can have the hole that holds pin 16 with the semicircle kissing merging on connecting axle 15 tops, as shown in Figure 3, be the mechanism of interlock mutually of connection-core 13 and latch hook 1, this mechanism also the tooth 17 on connection-core top with the D of latch hook 1 end with tooth 17 mutually the tooth 18 of interlock form, as shown in Figure 4, pellet shot from a slingshot group number in the lock can have the 3-7 group, three pellets shot from a slingshot and a marble spring 11 are arranged in every group, the length of the pellet shot from a slingshot 8 in each group is different with the difference of key bit, when key inserts in the keyhole 7, the interface of pellet shot from a slingshot 8 and pellet shot from a slingshot 9 should match with the fitting face of lock core and lock body and lock core can be rotated and mobile, wall thickness between two holes of length and lock body of pellet shot from a slingshot 9 in each group equates, therefore after inserting key, pellet shot from a slingshot 9 should match with the fitting face of connection-core and lock body with the interface of pellet shot from a slingshot 10, connection-core 13 can be driven by latch hook and moves up and make latch hook break away from the hole of lock body, pellet shot from a slingshot hole on the connection-core 13 is obstructed, marble spring 11 and pellet shot from a slingshot 10 place the obstructed blind hole of connection-core 13, mounting 12 is that the hole of sealing assembling pellet shot from a slingshot 9 is used, so even mounting 12 is taken away and marble spring and pellet shot from a slingshot can not be taken out and lock is opened.

After when unblanking key being inserted keyhole, at first key is upwards pushed away to make to move on the lock core and will move on the latch hook and drive and move on the connection-core 13 and make the D of latch hook 1 hold lock body 4, key is rotated lock core 6 and is driven the latch hook rotation and the D of latch hook is held and connection-core 13 disengagings then, and lock is opened.Get final product on the contrary by said sequence during locking.

Pellet shot from a slingshot top lock with connection-core of the present utility model, increased connection-core at the D of latch hook end, increased the safety of lock, when all coincideing with corresponding fitting face, just can open interface, the pellet shot from a slingshot hole does not communicate with the external world, can not take out even mounting is taken away pellet shot from a slingshot, be a kind of safe, practical pellet shot from a slingshot top lock.
