Small lock

A small lock, especially a small front bead seat provided with a simplified structure in the lock, so that the lock can effectively reduce the overall volume and achieve miniaturization effect.

Press, the general lock, when unlocking, mainly by inserting the unlocking part of the key into the lock case, so that the unlocking part is sleeved with the front bead seat to form a positioning, and then turning the key, so that the unlocking part of the key drives the front bead seat to rotate to unlock Therefore, in order to smoothly connect the unlocking portion of the key to the front bead seat to form a positioning, a ring wall is generally disposed in a direction away from the rear bead seat on the periphery of the front bead surface, and positioning is provided on the ring wall. The structure is such that the unlocking portion of the key is inserted into the ring wall of the front bead seat, and generally the plurality of front bead tips disposed in the front bead seat are stopped by the ring wall, so that the position of the plurality of front bead tips is close to the ring The wall, away from the lock, causes the overall bulk of the lock to be bulky, which is not conducive to miniaturization.

Therefore, how to solve the above-mentioned problems and shortcomings is the subject of research and development that the relevant industry is eager to develop.

The main purpose of the creation is to use the action of the front bead seat to form a positioning by key sleeve, and to unlock the front bead seat by pushing the action part without adding a ring wall to the periphery of the front bead seat, Simplify the structure of the front bead seat, effectively reduce the overall volume of the lock, and achieve the effect of miniaturization.

The second purpose of this creation is to use the front part of the bead seat to stop the front bead, so that the front bead can approach the lock, and the overall volume of the lock can be reduced to achieve the miniaturization effect.

In order to achieve the above purpose, the small lock of the present invention is provided with a lock case and a front bead seat and a rear bead seat arranged side by side in the lock case, and the front bead seat is formed on the side of the rear bead seat to form a body portion, and the body portion is away from the body. The other side of the rear bead seat has an actuating portion for key positioning. The surface of the actuating portion of the front bead seat is concavely provided with an actuating groove. When the key is inserted into the lock case and sleeved on the outside of the actuating portion to form a positioning, the key is disposed in the key. The pushing part will enter the actuating slot, so that the key pushes the moving groove when the key is unlocked to unlock the front bead seat.

In the above small lock, the actuating groove of the front bead is formed by recessing the actuating portion away from the other side surface of the main body portion.

In the above-mentioned small lock, the front bead seat is arranged in a ring-shaped arrangement on the outer side of the actuating portion, and a plurality of bead-tip grooves are arranged, and the front bead tips are disposed in the plurality of bead-tip grooves, and the bead-tip grooves are arranged by the positioning space and the accommodating space. The positioning space is formed by the recessed side surface of the actuating portion, so that the actuating portion is formed with a stop surface on the other side of the positioning space away from the main body portion, and the accommodating space is disposed in the body portion, and the accommodating space is connected to the positioning space.

Please refer to the first to third figures. As can be clearly seen from the figure, the small lock of the present invention is provided with a lock case 1 and a front bead seat 2 and a rear bead seat 3 which are arranged side by side in the lock case 1 and A lock core 4 is disposed in the front bead seat 2 and the rear bead seat 3, wherein:

The lock case 1 has a hollow cylindrical shape, and the inner surface is concavely provided with an elongated limit groove 11 , and the surface is recessed with an inlet port 12 communicating with the limit groove 11 .

The front bead seat 2 is formed with a body portion 21 on the side of the rear bead seat 3, and the main body portion 21 extends from the other side of the rear bead seat 3 with an actuating portion 22 for positioning the key 5, and the front bead seat 2 is actuated. a plurality of bead tips 23 are arranged in the outer annular portion of the portion 22, and the front bead tips 24 are disposed on the plurality of bead tips 23; wherein the body portion 21 is formed with an abutting surface 211 near the surface of the actuating portion 22, The actuating portion 22 is recessed from the other side surface of the main body portion 21, and the bead groove 23 is formed by the positioning space 231 and the accommodating space 232. The positioning space 231 is recessed by the side surface of the actuating portion 22. Forming, the actuating portion 22 is formed with a stop surface 222 on the other side of the positioning space 231 away from the main body portion 21, and the accommodating space 232 is disposed in the main body portion 21, and the accommodating space 232 is connected to the positioning space 231, allowing the front The peripheral edge of the bead tip 24 is stopped by the stop surface 222 of the actuating portion 22, and the other peripheral edge is exposed outside the actuating portion 22 to prevent the front bead tip 24 from falling out of the front bead seat 2.

The rear bead seat 3 is internally provided with a plurality of bead tips 31 opposite to the front bead tips 24 of the front bead seat 2.

The lock core 4 is inserted through the center portion 21 of the front bead seat 2, the actuating portion 22, and the rear bead seat 3, and is located inside the plurality of bead tip grooves 23 and the plurality of rear bead tips 31.

Referring to the third and fourth figures, it can be clearly seen from the figure that the key 5 applied to the present invention has an unlocking portion 51 and a grip portion 52 disposed on one side of the unlocking portion 51, the unlocking portion 51. A positioning groove 511 is defined in the outer surface of the positioning groove 511, and a plurality of stopping grooves 512 are disposed on the inner side of the positioning groove 511. A limiting portion 514 is protruded from the outer surface of the portion 51.

Referring to the second to seventh figures, it can be clearly seen from the figure that when the creation is unlocked, the grip portion 52 of the key 5 is held, and the unlocking portion 51 of the key 5 is inserted into the lock case 1. The surface of the unlocking portion 51 of the key 5 is abutted against the abutting surface 211 of the main body portion 21 of the front bead 2 . At this time, the limiting portion 514 of the unlocking portion 51 enters the limiting slot 11 from the inlet 12 of the locking case 1 . The urging portion 513 of the unlocking portion 51 enters the actuating groove 221 from the surface of the actuating portion 22, and the positioning groove 511 of the unlocking portion 51 of the key 5 is sleeved on the outer side of the actuating portion 22 to form a positioning. The plurality of stop grooves 53 are arranged to push the bead tips 24 before being exposed outside the actuating portion 22, so that the bead tips 24 and the rear bead tips 31 of the front bead seat 2 and the rear bead seat 3 are pressed to be in the same horizontal line, and then The grip portion 52 of the key 5 is pulled, and the pushing portion 513 of the unlocking portion 51 pushes the movement groove 221 to rotate the front bead seat 2 to unlock, and the limiting portion 514 of the unlocking portion 51 is inside the lock case 1 The bit groove 11 is displaced to limit the rotation angle of the key 5.

Therefore, this creation is a problem that can solve conventional problems and lacks. The key technologies are:

(1) Using the actuating groove 221 provided on the actuating portion 22 of the front bead seat 2, the unlocking portion 51 of the key 5 is sleeved on the outer side of the actuating portion 22 to form a positioning, and the moving groove 221 can be pushed to make the front bead seat 2 Rotate to unlock, without adding a ring wall on the periphery of the front bead 2 to simplify the structure of the front bead 2, effectively reducing the overall volume of the lock, and achieving miniaturization.

(2) Using the actuating portion 22 of the front bead seat 2 to stop the front bead tip 24, so that the front bead tip 24 can approach the lock core 4, and the overall volume of the lock can be reduced to achieve the miniaturization effect.
