[specific embodiment]
1 to 12 pair of the utility model is further described with reference to the accompanying drawing:
A kind of lock core, includes the key 3 that lock housing 1, lock gall 2 and cooperation lock core use, and the lock housing 1 is equipped with peace
Hole 11 is filled, be rotatably connected the lock gall 2 in the mounting hole 11, and the key for the key 3 insertion is offered on the lock gall 2
Keyhole 20 offers the marble hole 21 communicated with keyhole 20 on 2 circumferential surface of lock gall, is movably set with bullet in the marble hole 21
Son 4, the key 3 are equipped with the tartar 31 cooperated with the pellet 4, offer on the inner wall of the mounting hole 11 of the lock housing 1
Dovetail groove 13 extending along the pivot center direction of lock gall 2, entering for described 4 one end of pellet, the slot bottom of the dovetail groove 13
Width is less than the opening width of dovetail groove 13, and the dovetail groove 13 has groove bottom 131 and connect with the two sides of groove bottom 131
Two trough wall surfaces 132, the groove bottom 131 and trough wall surface 132 are plane.The slot bottom of the utility model dovetail groove 13 is wide
Spend that L is less than the opening width L ' of dovetail groove 13 and groove bottom 131 and trough wall surface 132 are all plane, therefore, 4 one end of pellet can be with
Swimmingly slide to from dovetail groove 13 on 11 inner wall of mounting hole or from 11 inner wall of mounting hole and slide to dovetail groove 13, this but also
Lock gall 2 rotates more smoothly relative to lock housing 1, is less prone to the phenomenon that gets stuck of lock gall 2.Relative to conventional lock cylinders, this reality
It is also saved the spring in conventional lock cylinders pellet component with novel and is made the volume of the product smaller, structure is more compact.
If it is small that groove bottom 131 with trough wall surface 132 is formed by angle, although pellet 4 slides into mounting hole from dovetail groove 13
11 inner walls are more smooth, but the snap-in function of the dovetail groove 13 is poor；If groove bottom 131 and trough wall surface 132 are formed by angle
Greatly, although the snap-in function of dovetail groove 13 is good, pellet 4 slides into 11 inner wall of mounting hole from dovetail groove 13 and has some setbacks.For this purpose,
Inventor has found that it is further preferred that the groove bottom 131 and any trough wall surface 132 are formed by angle and exist
Following range: effect is best at 35 ° to 45 °, and being formed by angle theta is 35 ° to 45 °, and the gradient of such trough wall surface 132 is more
Gently make pellet 4 from dovetail groove 13 slide into 1 inner wall of lock housing during it is smooth after simultaneously snap-in function effect it is more excellent.
It is further preferred that preferably select the groove bottom 131 and any trough wall surface 132 be formed by angle for
40°。
It is further preferred that the junction of the inner wall of the mounting hole 11 and any trough wall surface 132 is that cambered surface makes it
Between junction can gentle transition.
It is further preferred that being additionally provided with the lateral pin placing groove 5 positioned at the two sides of keyhole 20, institute on 2 circumferential surface of lock gall
State the side tumbler hole 22 for offering on 2 circumferential surface of lock gall and communicating with the lateral pin placing groove 5, keyhole 20, the side tumbler
Be equipped with side tumbler spring 9 in hole 22 and drive mobile side tumbler 6 by key 3, be equipped in the lateral pin placing groove 5 with
The lateral pin 7 that side tumbler 6 cooperates is additionally provided with the lateral pin for pushing lateral pin 7 mobile toward 6 direction of side tumbler in the lock gall 2
The inner wall of spring 8, the mounting hole 11 of the lock housing 1 is equipped with card slot 14, and the two sides of the key 3 are designed with snakelike tank
32, the side tumbler 6 is equipped with v-notch slot 61 and the cylinder 62 with the snakelike tank 32 cooperation, is not inserted into described
When key 3, the v-notch slot 61 of the side tumbler 6 is mutual with 5 position of lateral pin placing groove under the effect of side tumbler spring 9
It is staggered and the lateral pin 7 of part is made to expose outside lateral pin placing groove 5 and cooperate with the card slot 14, when being inserted into the key 3, institute
It is opposite with 5 position of lateral pin placing groove so that lateral pin 7 to state the v-notch slot 61 of side tumbler 6 under the action of snakelike tank 32 thereon
By the promotion of lateral pin spring 8 completely into lateral pin placing groove 5.
It is pressed against in v-notch slot 61 under the effect of lateral pin spring 8 it is further preferred that described 7 one end of lateral pin is equipped with
Top splenium 71, the other end, which is equipped with after top splenium 71 is detached from v-notch slot 61, to be exposed outside lateral pin placing groove 5 and cooperates with card slot 14
Detent portion 72, the lateral pin 7 of the part is detent portion 72, and the top splenium 71 is taper, and the detent portion 72 is swallow
Tail shape.
It is further preferred that the length of the pellet 4 is greater than the depth of marble hole 21.
It is further preferred that the end that the pellet 4 enters that one end in dovetail groove 13 is taper.
The working principle of the utility model is as follows:
After user is inserted into key 3, key 3 will drive the side tumbler 6 of two sides mobile so that in side tumbler 6
V-notch slot 61 it is all opposite with the position of top splenium 71 on lateral pin 7；At this point, lateral pin 7 makes cross under the effect of lateral pin spring 8
The detent portion 72 of pin 7 bounces back in lateral pin placing groove 5 after completely disengaging the card slot 14 in lock housing 1, and at this moment lock gall 2 can rotate
Get up to be unlocked；In the rotation process of lock gall 2, one end of pellet 4 is the mounting hole 11 that lock housing 1 is slided to from dovetail groove 13
The tartar 31 of the other end of pellet 4 and key 3 cooperation on inner wall；After user extracts key 3, the V type of side tumbler 6 is lacked
Mouth slot 61 mutually staggers with 5 position of lateral pin placing groove under the effect of side tumbler spring 9 and the detent portion 72 of lateral pin 7 is retracted
Cooperate outside to lateral pin placing groove 5 and with the card slot of lock housing 1 14, such lateral pin 7 can play the role of detent so that 2 phase of lock gall
It is circumferentially fixed for lock housing 1.
When user's inserting error key, since the tartar 31 of mistake on the key can not match with pellet 4, therefore wrong key
Spoon, which can act on 4 one end of pellet and withstand on always in dovetail groove 13, slide into it can not from dovetail groove 13 in 1 mounting hole 11 of lock housing
On wall, pellet 4 also just plays the role of blocking the rotation of lock gall 2 with lateral pin 7 together, and which further enhances the locking of lock core effects
Fruit.
