Description

An Improved Blade Pin Lock Using a Milled Groove Key

technical field

The utility model belongs to locks, in particular to an improved blade pin lock which adopts a milling tooth groove key.

Background technique

Among the existing locks, there is a kind of lock that utilizes blades to cooperate with locking side columns to lock. The lock includes a lock body and a lock core in the lock body. 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. In addition, in the unlocked state, the lock cylinder only rotates on the circumference relative to the lock body, and the lock is opened through the linkage between the lock ruler fixed at the tail of the lock cylinder and the lock tongue. Such lock cylinders cannot be used for locks that control the deadbolt along the axis of the cylinder.

Utility model content

The purpose of this utility model is to address the above situation, to provide an improved blade tumbler lock with milling groove key, which can increase the amount of keys and reduce the mutual opening rate, and can control the deadbolt along the axis of the lock cylinder.

The technical solution to achieve the purpose of this utility model is: the improved blade tumbler lock using the milling groove key of the utility model includes a lock head and its matching key; the lock head includes a lock body, a lock cylinder in the lock body, and a lock The core is axially provided with a number of blade pin groups consisting of two blade pin pins. In the blade pin pin groups on the same side, the middle part of one pin pin and the end of the other pin pin are respectively provided with keyholes extending into the keyhole. The other side of each blade pin is provided with a V-shaped groove, and the blade pin return spring is respectively set on the front lock core corresponding to each blade pin; There is a locking side column that can match the V-shaped groove on the blade, a stopper is provided on the lock cylinder, a locking side column reset elastic device is provided between the stopper and the locking side column, and a locking rod is provided at the end of the lock cylinder , the lock body is provided with a groove corresponding to the locking side column groove on the lock cylinder; the lock body is provided with a through spiral groove, and the lock cylinder is provided with a protruding part that matches the spiral groove on the lock body;

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. Since the lock core is provided with a protruding part that matches the spiral groove on the lock body, when the key is inserted to unlock the lock, the protruding part on the lock core will move along the spiral groove on the lock body during the process of turning the lock core, making the lock core While making circular movement relative to the lock body, it also makes axial movement, and only needs to rotate the lock cylinder in the opposite direction when locking. The lock head of the utility model utilizes the axial movement of the lock cylinder to achieve the purpose of controlling the dead bolt in the axial direction, so it can be used for locksets in such occasions.

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

Detailed ways

Example 1

See Fig. 1, Fig. 2, Fig. 5, the lock end of the present utility model comprises lock body 1, the lock core 2 in lock body 1, and the lock core 2 is provided with several blade pin holes 11 horizontally along the axial direction, and the blade pin pins The hole 11 communicates with the axially arranged keyhole 9; each vane pin hole 11 is provided with two vane pins 6, 16 stacked as a group, and the middle part of the vane pins 16 and the blade pins in the vane pin group on the same side The ends of 6 are respectively provided with protrusions 8 and 10 extending into the keyhole, and the other sides of the blade pins 6 and 16 are respectively provided with V-shaped grooves 7, and the lock core 2 corresponds to the blade pins 6 in each group. , 16 are relatively respectively provided with blade return springs 5,12; the lock core 2 is provided with a locking edge column groove 3, and the locking edge column groove 3 is provided with a locking edge that can cooperate with the V-shaped groove 7 on the blade pins 6,16. Column 4 is provided with a stopper 14 on the notch of the locking side column groove of the lock core, and a locking side post return spring 15 is provided in the groove 13 corresponding to it on the stopper 14 and the locking side post 4, and the lock core 2 tail A lock rod 19 is provided, and the lock body 1 is provided with a groove 17 corresponding to the locking side column groove 3 on the lock cylinder 2 (see FIG. 3 ). The lock body 1 is provided with a through spiral groove 21 . A pin 20 matching with the helical groove 21 on the lock body is provided.

The matching key with the lock head of the present utility model is shown in Fig. 7, and comprises key piece 18, is respectively provided with outer milling tooth groove 25 and inner milling tooth groove 22 in the side and the middle part of one side of key piece 18, on the side of outer milling tooth groove The wall 24 and a side wall 23 of the inner milling groove are provided with dental flowers.

working principle

See Fig. 3, Fig. 4, Fig. 5, when the key blade 18 is inserted into the lock cylinder, the tooth patterns on the side walls of the outer milling tooth groove and the inner milling tooth groove on the key blade 18 are respectively connected with the protrusions on the blade pins 6 and 16. 10 and 8 cooperate to force the V-shaped grooves on each group of blade pins in the lock cylinder 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 Back in the lock cylinder 2 from the groove 17 on the lock body, at this moment the lock cylinder 2 can rotate relative to the lock body 1 to become an unlocked state, when the key blade 18 rotates the lock cylinder 2 in the direction of the arrow (see Figure 6), the lock cylinder The pin 20 on the 2 moves along the spiral groove 21 on the lock body, so that the lock core 2 moves to the right along the axis at the same time, and the lock bar 19 that is located on the lock core 2 to control the dead bolt returns to the lock body. When locking, use The key rotates the lock cylinder in the opposite direction so that the lock bar 19 can be stretched out of the lock body to limit the dead bolt; Reset, the V-shaped groove 7 on the blade pins forces the locking side column 4 to withdraw from the V-shaped groove when resetting, and at the same time makes the other side of the locking side column 4 extend into the groove 17 of the lock body. Lock core 2 and lock body 1 are connected as a whole, at this moment lock core 2 can not rotate relative to lock body 1 and become locked state (referring to Fig. 1, Fig. 2).
