The lock core is provided with a locking side column that matches the V-shaped groove on the blade. The blade in this lock can only be used with an ordinary key. There is only one form of tooth groove, or the tooth groove is set on the side of the key blade (external milling tooth groove), or it is set in the middle of the key blade (internal milling tooth groove), so that the key quantity of the lock is limited, The mutual opening rate is relatively high, and the anti-theft performance is affected.

Utility model content

The purpose of this utility model is to provide an improved blade pin lockset using a milled groove key which can increase the amount of keys and reduce the mutual opening rate in view of the above situation.

The technical solution to achieve the purpose of this utility model is: the improved blade pin lockset adopting the milling groove key of the utility model includes a lock head and a matching key; the lock head includes a lock body and a lock cylinder in the lock body, The lock cylinder is provided with a number of blade pin groups consisting of two blade pin pins in the axial direction, and the middle part of one pin pin and the end of the other pin pin in the vane pin set on the same side are respectively provided with keys extending into the key. The bump in the hole is provided with a V-shaped groove on the other side of each blade pin, and the blade pin return spring is respectively set on the front lock cylinder corresponding to each blade pin; There is a locking side column that can be matched with the V-shaped groove on the blade, a stopper is provided on the lock cylinder, and a locking side column reset elastic device is provided between the stopper and the locking side column, and the lock body and the lock cylinder The locking side column groove on the upper is correspondingly provided with a groove;

The key matched with the lock head includes a key piece, and the side and middle of one side of the key piece are respectively provided with an external milling tooth groove and an internal milling tooth groove, and on the side wall of an external milling tooth groove and the inner milling tooth groove There is tooth flower on one side wall.

The elastic device for restoring the locking side post is to arrange a spring between the lock cylinder stopper and the locking side post, and a magnetic block with the same polarity can also be correspondingly arranged between the lock cylinder stopper and the locking side post.

The utility model is characterized in that it can use an internal and external milling tooth groove key which is different from the ordinary key structure. Since the adopted key is equipped with both the external milling tooth groove and the internal milling tooth groove, the key quantity of the lock is increased and the mutual opening is reduced. rate, so that the lock has better anti-theft performance.

Below in conjunction with accompanying drawing, the utility model is further described.

Detailed ways

Example 1

See Fig. 1, Fig. 2, the lock head of the present utility model comprises lock body 1, the lock core 2 in lock body 1, and lock core 2 is provided with several blade pinholes 11 horizontally along the axial direction, and blade pinhole 11 and The key holes 9 arranged in the axial direction are connected; each blade pin hole 11 is provided with two blade pins 6 and 16 stacked as a group, and the middle part of the blade pin 16 and the end of the blade pin 6 in the blade pin group on the same side are arranged. The upper part is respectively provided with protrusions 8,10 extending into the keyhole, and the other side of the blade pins 6,16 is respectively provided with a V-shaped groove 7, and the corresponding blade pins 6,16 in each group are opposite to each other on the lock core 2. The blade return springs 5, 12 are arranged respectively; the lock core 2 is provided with a locking side column groove 3, and a locking side column 4 which can cooperate with the V-shaped groove 7 on the blade pins 6, 16 is arranged in the locking side column groove 3, A stopper 14 is arranged on the notch of the locking side post groove of the lock cylinder, and a locking side post return spring 15 is arranged in the groove 13 corresponding to it on the stopper 14 and the locking side post 4, and the lock body 1 is connected with the lock core The locking side column groove 3 on 2 is correspondingly provided with the groove 17 (referring to Fig. 3).

The matching key with the lock head of the present utility model is shown in Fig. 5, and comprises key piece 18, is respectively provided with outer milling tooth groove 22 and inner milling tooth groove 19 in the side and the middle part of one side of key piece 18, on the side of outer milling tooth groove The wall 21 and a side wall 20 of the inner milling groove are provided with dental flowers.

working principle

See Fig. 3, Fig. 4, after the key blade 18 is inserted into the lock cylinder, the teeth flower on the side wall of the outer milling tooth groove and the inner milling groove on the key blade 18 is connected with the protrusions 10, 8 on the blade pins 6, 16 respectively. Cooperate to force the V-shaped grooves on the pins of each group of blades in the lock core 2 to align, and under the action of the return spring 15, one side of the locking side column 4 enters the V-shaped groove 7 of the blade, and the other side enters the V-shaped groove 7 from the lock body. Back into the lock core 2 in the groove 17 on the top, at this moment the lock core 2 can rotate relative to the lock body 1 to become an unlocked state; Reset under the action of 12, the V-shaped groove 7 on the blade pin will force the locking side column 4 to withdraw from the V-shaped groove when resetting, and at the same time make the other side of the locking side column 4 extend into the groove 17 of the lock body, and pass through the locking edge. The post 4 connects the lock core 2 and the lock body 1 as a whole, and at this moment the lock core 2 cannot rotate relative to the lock body 1 to become a locked state (see Fig. 1 and Fig. 2 ).

Example 2

As shown in Figure 6, a magnetic block 23 can also be set on the notch of the locking side column groove on the lock cylinder, and a magnetic block 24 with the same polarity as the magnetic block 23 is correspondingly arranged in the groove on the locking side column, Utilize the repulsive force between the magnetic block 23 and the magnetic block 24 to make the locking side column return (see FIG. 7 ). Other structures are the same as in Example 1.
