Referring to the first, second and third figures, the present invention provides an automatic locking structure improvement, comprising: a lock A, the lock A comprises a lock seat 10, a lock core 20, A torsion spring 30, a carrier member 40, a linkage member 50, a lock lever 60, a control member 70, a spring 80 and a lock housing 90.

The center of the lock base 10 is provided with a lock hole 11 , and a control slot 12 is disposed at one end of the lock hole 11 . The end of the lock base 10 is provided with a coupling hole 13 , and the control slot 12 cooperates with the coupling hole 13 .

The lock core 20 is disposed in the lock hole 11 and extends into the control slot 12 .

The torsion spring 30 is disposed between the lock core 20 and the control slot 12, and normally provides a torsion force in which the lock core 20 returns to a locked state.

The driving member 40 is sleeved in the control slot 12 of the lock core 20 and has an elongated shape with a rotatable longitudinally extending shaft 41.

The linking member 50 is disposed in the control slot 12, and cooperates with the shape and the rotating position of the driving member 40 to generate a sliding interlocking action, and the inner locking opening and the external pushing locking action. The linking member 50 has a linking groove 51 on the side. The driving member 40 is coupled to be driven by a hooking manner, and a center of the extending direction of the driving member 40 is disposed with a locking rod groove 52. The connecting member 50 is provided with a notch 53 in the direction of the locking core 20, and the missing portion 53 The slot 53 provides interference avoidance with the lock core 20 (see Figures A and 8).

The lock lever 60 has a long rod shape, and a thin recessed groove 61 is disposed in the center for fixing in the lock rod slot 52. One end of the lock rod 40 is provided for abutting, and the other end is provided with a locking end 62 for locking. A limiting slot 63 is defined in the locking end 62. The locking end 62 can be controlled to penetrate the coupling hole 13. The locking lever 60 has a longitudinally extending shaft 64 in a matching shape and a sliding direction.

The control member 70 is disposed in the coupling hole 13 and can generate high and low displacements. The outer limiting portion of the limiting slot 63 is provided with a limiting piece 71.

The spring 80 is disposed in the coupling hole 13 for elastically pushing the control member 70 outwardly.

The lock case 90 is provided with the lock seat 10, the lock core 20, the torsion spring 30, and the drive The assembly 40, the linkage member 60, the lock lever 60, the control member 70 and the spring 80 are combined. The lock housing 90 is made of metal, and the outer cover is covered with a plastic shell, and at least one end is provided with a jack 91. .

a lock B having a first joint end B1 and a second joint end B2, And the combination of the plurality of links B0, the adjacent link B0 can be pivoted, the first joint end B1 is located at the front end of the first link B0, and the second joint end B2 is located at the last link The end of B0, and the first joint end B1 is provided with a keyhole B3.

The first binding end B1 of the lock member B is an insertion hole 91 coupled to one end of the lock head A, And the locking hole B3 of the first joint end B1 can provide the locking end 62 of the lock rod 60 to pass the lock, the second joint end B2 of the lock member B is the lock head The other end of the A is combined, and the lock core 20 is disposed to expose the lock case 90 to provide a key rotation to achieve the purpose of locking or unlocking, and when the control member 70 is in the coupling hole 13, the first The joint end B1 is contactable and pressed against the control member 70.

When it is locked, see the first combination of the lock B as shown in Figures 4, 5 and 6. The end B1 is inserted into the coupling hole 13, and the control member 70 is pressed down to compress the spring 80. The lock core 20 rotates to drive the linkage member 50 and the lock lever 60 to slide out. The rod 60 and the longitudinally extending shafts 41, 64 of the lock rod 60 are parallel and the locking end 62 of the lock rod 60 passes through the lock hole B3, and the lock rod 60 and the longitudinally extending shafts 41, 64 of the lock rod 60 are parallel to each other. The purpose of the anti-theft.

In the unlocked state, see Figure 7, 8, 9, and 10, turning the lock with the key. The core 20 and the driving member 40. At this time, the torsion spring 30 is also twisted and twisted, so that the linking member 50 is pulled back by the driving member 40 by the interlocking groove 51, and the locking rod 60 is also pulled back and released from the locking hole B3. The first joint end B1 of the lock member B can be pulled out, and the outer control unit 70 loses the restriction force and is ejected by the spring 80. The limiting piece 71 of the control member 70 is blocked by the limiting slot 63 of the locking lever 60, so that the torsion spring 30 is stored by the interlocking torsion pressure. Otherwise, when the first binding end B1 of the locking member B is inserted The control member 70 is pressed down and the spring 80 is compressed. The limiting slot 63 of the locking lever 60 is lost by the limiting piece 71 of the control member 70. The torsion spring 30 releases the pressure and rotates the button. The lock core 20 drives the link member 40 and pushes out the link member 50 and the lock bar 60, so that the locking end 62 of the lock bar 60 passes through the lock hole B3 again, thereby achieving the purpose of automatic locking.

In addition, a receiving groove 131 is disposed on a side of the coupling hole 13 of the lock base 10, and the receiving groove is A compression spring 132 is disposed in the 131, and a topping member 133 is pressed against the receiving groove 131 by the compression spring 132. The abutting member 133 does not fall out of the receiving groove 131, and the first combination of the locking member B When the end B1 extends into the coupling hole 13, it can be pressed by the compression spring 132 and the abutting member 133 with an appropriate force.

From the structure of the above specific embodiment, the following benefits can be obtained: it is locked In the state, the longitudinal extension shafts 41, 64 of the lock lever 60 and the lock lever 60 are parallel and the locking end 62 of the lock lever 60 passes through the lock hole B3, and the longitudinal extension shafts 41, 64 of the lock lever 60 and the lock lever 60 are parallel. Without the gap, the anti-theft purpose of preventing the knocking and unlocking can be achieved; when the unlocking state is to be locked, the torsion spring 30 is first connected to the torsional pressure storage, and the first joint end B1 of the lock member B is inserted back to the joint hole 13 to be pushed. The control member 70 causes the limiting slot 63 of the locking lever 60 to be lost by the limiting piece 71 of the control member 70. The torsion spring 30 releases the locking member 20 and rotates the driving member 40 and pushes the linking member 50 and the lock. The lever 60 allows the locking end 62 of the lock lever 60 to pass through the lock hole B3 again, thereby achieving the purpose of automatic locking.

In summary, this creation has indeed reached a breakthrough structure, and has changed The content of Liangzhi's creation can at the same time be able to achieve industrial utilization and progress. When complying with the provisions of the Patent Law, the company will file a new type of patent application according to law, and invite the examination committee of the bureau to grant legal patent rights.
