[0052] The linkage turntable 40 is rotatably installed in the assembly space, and a plurality of give-way grooves 41 are arranged in sequence along the circumferential direction on the circumferential side of the linkage turntable 40, and a first linkage part 42 and a second linkage part 43 arranged in sequence along the circumferential direction are provided on the linkage turntable 40; preferably, in this embodiment, three give-way grooves 41 are provided, and the three give-way grooves 41 are arranged in sequence along the circumferential direction on the circumferential side of the linkage turntable 40 with uniform intervals, and a driving wall 44 for pushing the lock tongue 20 is formed on the circumferential side wall of the linkage turntable 40 between two adjacent give-way grooves 41, and the first linkage part 42 and the second linkage part 43 are both formed on the side of the same driving wall 44 facing the lock cylinder 30.

[0053] The driving unit 70 is installed in the assembly space, and the slider 60 can be movably installed in the assembly space and connected to the driving unit 70; one end of the transmission member 50 is connected to the slider 60, and the other end can selectively act on the first linkage part 42 or the second linkage part 43; the driving unit 70 drives the slider 60 to move, and the slider 60 links the transmission member 50 to move; the transmission member 50 pushes the first linkage part 42 or the second linkage part 43 to move, so as to drive the linkage turntable 40 to rotate clockwise or counterclockwise, so that the lock tongue 20 retracts into the corresponding give way groove 41 to unlock, or the linkage turntable 40 pushes the lock tongue 20 to disengage from the corresponding give way groove 41 and extend it to lock; here, the driving unit 70 is preferably a magnetic valve. Here, a return spring (not shown in the figure) is arranged in the assembly space; one end of the return spring is connected to the lock tongue 20, and the other end is connected to the housing 10; the lock tongue 20 retracts into the corresponding clearance groove 41 to unlock under the action of the return spring as the linkage rotating disk 40 rotates, or is disengaged from the corresponding clearance groove 41 and extends out to lock and squeeze the return spring. Preferably, in this embodiment, the end of the lock tongue 20 facing the linkage rotating disk 40 has a convex portion 21 with a triangular cross section, and correspondingly, the clearance groove 41 is a groove with a triangular cross section, and the convex portion 21 is embedded in or disengaged from the corresponding groove as the linkage rotating disk 40 rotates. The end of the lock tongue 20 away from the linkage rotating disk 40 is provided with a locking portion 23 protruding outward, and the locking portion 23 is provided with a locking groove 24 recessed inward to lock with the outside.

[0054] The lock core 30 is installed in the assembly space, and the key hole of the lock core 30 is exposed outside the housing 10. One end of the lock core 30 is connected to the linkage turntable 40; rotating the lock core 30 drives the linkage turntable 40 to rotate, so that the lock tongue 20 is retracted into the corresponding give way groove 41 to unlock, or the linkage turntable 40 pushes the lock tongue 20 to disengage from the corresponding give way groove 41 and extend to lock; in this way, when manually unlocking or locking, it is only necessary to insert the key into the key hole of the lock core 30 and rotate it at the same time to drive the linkage turntable 40 to rotate, so that the linkage lock tongue 20 is disengaged from the corresponding give way groove 41 and extends to lock or retracts into the corresponding give way groove 41 to unlock.

The locking block 81 is embedded in or disengaged from the corresponding giving way groove 41 as the linkage turntable 40 rotates; when the lock tongue 20 extends from the lock hole 11 to lock, the locking block 81 moves into the corresponding giving way groove 41. At this time, the locking block 81 feeds back information to the position switch 80 that it is in a locked state; when the lock tongue 20 retracts from the lock hole 11 to unlock, the locking block 81 moves out of the corresponding giving way groove 41. At this time, the locking block 81 feeds back information to the position switch 80 that it is in an unlocked state.

[0057] One end of the transmission member 50 is rotatably connected to the slider 60 through a positioning column 51, and a slide groove 12 is provided in the shell 10. The slider 60 is slidably adapted in the slide groove 12. A stop wall 13 for limiting the slider 60 is provided on one side of the slide groove 12 at one end of the shell 10 away from the driving unit 70 along the extending direction of the slide groove 12. The end of the slider 60 away from the driving unit 70 is limited by the stop wall 13 to limit the sliding stroke of the slider 60; a limiting wall 14 for limiting the rotation of the transmission member 50 is provided on one side of the slide groove 12 at one end of the shell 10 close to the driving unit 70 along the extending direction of the slide groove 12, and a limiting plane 52 is provided at one end of the transmission member 50 away from the linkage turntable 40. The limiting plane 52 is limited by the limiting wall 14 as the transmission member 50 rotates to limit the rotation stroke of the transmission member 50.

[0058] And, in this embodiment, the housing 10 includes a first housing 16 and a second housing 17 which are spliced ​​with each other, the first housing 16 and the second housing 17 enclose the assembly space, the keyhole of the lock core 30 is exposed outside the second housing 17, and the lock hole 11 is formed on the side wall of the first housing 16. A wire groove 18 is provided at the bottom of the first housing 16, and both ends of the wire groove 18 are connected to wire holes, and the wire holes are connected to the assembly space, so that the cables can be arranged in a hidden manner to avoid the phenomenon of cables being exposed and messy; in this embodiment, a wire is arranged in the wire groove 18, one end of the wire extends out of the housing 10 and is connected to a connection port, and a plurality of positioning bosses 101 are protruding downward from the bottom of the first housing 16, so that the bottom of the housing 10 does not directly contact the installation surface.

[0059] Its general working principle is as follows:

[0060] like Figure 7 As shown, in the initial state (unlocked state): the lock tongue 20 is embedded in the clearance groove 41, at this time, the slider 60 and the transmission member 50 are both in the initial position, the lock block 81 is separated from the corresponding clearance groove 41 and abuts against the outer peripheral side wall of the toggle wall 44 located on the left side of the lock tongue 20, and the return spring is in the open state;

[0061] When automatic locking is required, the driving unit 70 drives the slider 60 to move in the first direction, the slider 60 links the transmission member 50 to move in the first direction, and the transmission member 50 pushes the second linkage part 43 to move, so as to drive the linkage turntable 40 to rotate counterclockwise. At this time, the toggle wall 44 located on the left side of the lock tongue 20 pushes the lock tongue 20 to move away from the linkage turntable 40 counterclockwise until the lock tongue 20 is separated from the yield groove 41 and extends out to lock. At this time, the lock tongue 20 abuts against the outer peripheral side wall of the toggle wall 44, the reset spring is in an extruded state, and the lock block 81 is embedded in another yield groove 41. On this basis, the driving unit 70 drives the slider 60 to move in a second direction opposite to the first direction, and the slider 60 links the transmission member 50 to move in the first direction. The locking member 50 moves in the opposite second direction, and the transmission member 50 pushes the first linkage part 42 to move, so as to drive the linkage rotating disk 40 to rotate clockwise, until the toggle wall 44 is separated from the lock tongue 20 in the clockwise direction, and the lock tongue 20 is retracted into the giving way groove 41 under the action of the expansion of the return spring, and is automatically unlocked. At this time, under the action of the tension of the return spring, the lock tongue 20 will push the linkage rotating disk 40 to rotate a certain angle in the clockwise direction, so that the transmission member 50 is away from the first linkage part 42 and the second linkage part 43, so that when the lock is manually locked or unlocked, the linkage rotating disk 40 and the first linkage part 42 and the second linkage part 43 will not affect the transmission member 50, and at this time, the locking block 81 is separated from the other giving way groove 41 and abuts against the outer peripheral side wall of the toggle wall 44 again;

[0062] When manual locking is required, at this time, the driving unit 70, the slider 60, and the transmission member 50 do not work. The key is inserted into the keyhole of the lock cylinder 30 and rotated at the same time to drive the linkage turntable 40 to rotate counterclockwise. At this time, the toggle wall 44 located on the left side of the lock tongue 20 pushes the lock tongue 20 to move away from the linkage turntable 40 counterclockwise until the lock tongue 20 is separated from the give way groove 41 and extends out to lock. At this time, the lock tongue 20 abuts against the outer peripheral side wall of the toggle wall 44, the return spring is in an extruded state, and the lock block 81 is embedded in the other give way groove 41. On this basis, the key is turned to drive the linkage turntable 40 to rotate clockwise until the toggle wall 44 is separated from the lock tongue 20 in a clockwise direction. The lock tongue 20 retracts into the give way groove 41 under the expansion action of the return spring and is manually unlocked. At this time, the lock block 81 is separated from the other give way groove 41 and abuts against the outer peripheral side wall of the toggle wall 44 again.

[0063] like Figure 8 As shown, in the locked state: the lock tongue 20 abuts against the outer peripheral side wall of a toggle wall 44, the return spring is in a squeezed state, and the lock block 81 is embedded in a yielding groove 41. At this time, the slider 60 and the transmission member 50 are both in the automatic locking position;

[0064] When automatic unlocking is required, the driving unit 70 drives the slider 60 to move, and the slider 60 is linked to the transmission member 50 to move, and the transmission member 50 pushes the first linkage part 42 to move, so as to drive the linkage rotating disk 40 to rotate clockwise until the toggle wall 44 is separated from the lock tongue 20 in the clockwise direction, and the lock tongue 20 is retracted into the other yielding groove 41 under the expansion action of the return spring and automatically unlocked. At this time, under the tension of the return spring, the lock tongue 20 will push the linkage rotating disk 40 to rotate a certain angle clockwise again, so that the transmission member 50 is away from the first linkage part 42 and the second linkage part 43, so that when manually locking or unlocking, the linkage rotating disk 40 and the first linkage part 42 and the second linkage part 43 will not affect the transmission member 50, and at this time, the lock block 81 is separated from the yielding groove 41 and abuts against the outer peripheral side wall of the toggle wall 44. On this basis, the driving unit 70 drives the slider 60 to move in the reverse direction to automatically lock;

[0065] When manual unlocking is required, the driving unit 70 and the slider 60 do not work. The key is inserted into the keyhole of the lock cylinder 30 and rotated at the same time to drive the linkage rotary disk 40 to rotate counterclockwise until the toggle wall 44 disengages from the lock tongue 20 counterclockwise, and the lock tongue 20 retracts into the give way groove 41 under the expansion action of the return spring and is manually unlocked. At this time, the lock block 81 disengages from the give way groove 41 and abuts against the outer peripheral side wall of the other toggle wall 44, and the first linkage part 42 pushes the transmission member 50 to make a certain give way rotation. On this basis, turning the key drives the linkage rotary disk 40 to rotate clockwise, and the toggle wall 44 pushes the lock tongue 20 clockwise to move away from the linkage rotary disk 40 until the lock tongue 20 disengages from the give way groove 41 and extends out for manual locking. At this time, the lock tongue 20 abuts against the outer peripheral side wall of the toggle wall 44, the return spring is in an extruded state, and the lock block 81 is embedded in the give way groove 41.

[0066] In summary, the design focus of the present invention is that it mainly drives the slider to move through the driving unit, the slider links the transmission member to move, the transmission member pushes the first linkage part or the second linkage part to move, so as to drive the linkage turntable to rotate clockwise or counterclockwise, so that the lock tongue retracts into the corresponding give way groove to unlock, or the linkage turntable pushes the lock tongue out of the corresponding give way groove to extend to lock, so that it realizes automatic unlocking and locking, and the linkage turntable is driven to rotate by rotating the lock core, so that the lock tongue retracts into the corresponding give way groove to unlock, or the linkage turntable pushes the lock tongue out of the corresponding give way groove to unlock. Extending and locking, in this way, manual unlocking and locking are realized, so that manual unlocking and locking can be integrated with automatic unlocking and locking, solving the problem that unlocking and locking cannot be performed when power is off or out of power, so that when power is off or out of power, only the key needs to be inserted into the keyhole of the lock core and rotated at the same time to drive the linkage turntable to rotate, so that the linkage lock tongue is separated from the corresponding give way groove and extended to lock or retracted into the corresponding give way groove to unlock. At this time, the linkage turntable will not react on the slider and the drive unit, providing a very light unlocking and locking method for manual unlocking or locking.
