[0029] The specific embodiments of the present invention will be further described with reference to the accompanying drawings.
[0030] A mechanical automatic lock comprises a guide plate 1 and a lock box plate assembly 2 connected to the guide plate 1. The lock tongue of the lock tongue assembly 3 and the inclined tongue of the inclined tongue assembly 5 enter and exit the lock box plate assembly 2 through the guide plate 1. A inclined tongue fork assembly 4, a lock tongue trigger starting hook assembly 6, and a lock tongue toggle plate assembly 9 are also provided in the lock box plate assembly 2. The lock tongue toggle plate assembly 9 is slidably and rotatably arranged at the rear part of the lock tongue assembly 3 relative to the lock tongue assembly 3 and is connected to the lock box plate assembly 2. The lock tongue toggle plate torsion spring 10 is provided at the rotating shaft of the lock tongue toggle plate assembly 9, which is used to push the lock tongue toggle plate assembly 9 to rotate and make the lock tongue assembly 3 pop out. The inclined tongue fork assembly 4 is detachably abutted against the rear end of the inclined tongue assembly 5. The inclined tongue fork assembly 4 is provided in the middle part of the lock box plate assembly 2. A lock tongue trigger starting hook assembly 6 is provided on the inner side of the lock box plate assembly 2. The lock tongue trigger starting hook assembly 6 is detachably hooked with the inclined tongue fork group.
[0031] A transmission locking hole 1001 and a guide groove 1002 are provided at the rear of the lock tongue assembly 3. The lock tongue assembly 3 slides relative to the lock tongue toggle plate assembly 9 through the guide groove 1002. One side of the lock tongue toggle plate assembly 9 is connected to the transmission locking hole 1001 through the first lock tongue toggle plate rivet 12 for rotation. The sliding of the lock tongue assembly 3 drives the lock tongue toggle plate assembly 9 to rotate.
[0032] The bolt toggle plate assembly includes a bolt toggle plate 11 and a second bolt toggle plate rivet 13. A limiting angle 1003 is provided on the outer side of the bolt toggle plate 11. The limiting angle 1003 abuts or separates with one end of the bolt trigger start hook assembly 6. The second bolt toggle plate rivet 13 abuts or separates with the bolt toggle plate torsion spring 10. The latch bolt fork assembly 4 includes a latch bolt push rod 19 and a latch bolt fork 20. One end of the latch bolt fork 20 is connected to one end of the latch bolt push rod 19 via a latch bolt fork connecting rivet 21. The other end of the latch bolt push rod 19 is located in the lock box plate assembly 2. The other end of the latch bolt fork 20 abuts against the lower part of the latch bolt assembly 5. The latch bolt fork 20 is provided with a rotating block hole and a clutch protrusion 1007 at the outer end.
[0033] A transmission point 1008 and a lock core rotation angle 1009 are provided on one side of the middle portion of the oblique bolt push rod 19 .
[0034] The lock tongue trigger starting hook assembly 6 includes a lock tongue limiting plate 14, a starting hook spring 7 and a starting hook 17. One end of the lock tongue limiting plate 14 is connected to the starting hook 17 through a starting hook connecting rivet 16. The starting hook 17 is connected to the lock box plate assembly 2 through a starting hook clutch rivet 15. The upper starting hook 17 is also provided with a starting hook spring rivet 18. One end of the starting hook spring 7 is fixed to the lock box plate assembly 2, and the other end is connected to the starting hook spring 7 by rivets.
[0035] The other end of the lock tongue limiting plate 14 is provided with a locking plate bayonet 1004 , and the locking plate bayonet 1004 is detachably abutted against the limiting angle 1003 of the lock tongue toggle plate assembly 9 .
[0036] A starting hook notch 1005 is provided at the end of the starting hook 17 , and the starting hook notch 1005 is detachably hooked with the bottom end of the inclined tongue assembly 5 .
[0037] A bolt baffle 1006 is provided at the rear end of the latch bolt assembly 5 , and the bolt baffle 1006 is detachably abutted against the latch bolt fork assembly 4 .
[0038] One end of the lock tongue torsion spring 10 extends to the screw limiter in the lock box plate assembly 2.
[0039] The inclined bolt is passively triggered and automatically pops out to complete locking, effectively avoiding friction and collision between the lock bolt assembly and the door frame, and eliminating the trouble of using keys or other manual methods to lock. The unique transmission opening clutch structure is simple, stable and reliable, and the door handle inside can be opened quickly.
[0040] The mechanical automatic lock locking process is as follows:
[0041] After the oblique tongue assembly 5 is retracted, the lock tongue is pulled to trigger the starting hook assembly 6, and the oblique tongue fork assembly 4 is separated. After locking, the lock tongue toggle plate torsion spring 10 pushes the lock tongue toggle plate assembly 9 to rotate, pushing the main tongue assembly 3 to pop out and complete the locking.
[0042] The process of opening the mechanical automatic lock is as follows:
[0043] The key and handle unlock by rotating the rotating block 8, pushing the latch bolt fork assembly 4, pushing the lock bolt toggle plate assembly 9 and the latch bolt fork 20, and retracting the main lock bolt assembly 3 and the latch bolt assembly 5 to complete the unlocking; at the same time, the latch bolt fork 20 pushes open the starting hook 17 and is hooked to the latch bolt assembly 5, so the handle and key will not trigger the lock bolt to pop out when opening the lock bolt assembly 3 and the latch bolt assembly 5.
[0044] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are readily apparent to those skilled in the art without departing from the scope of the present invention.
