Since the spring force of the two first springs 9 may be reduced when the bolt 3 stretches out, the condition that the bolt 3 does not stretch out in place may occur, so the rotating shaft 18 of the driving gear 12 is provided with the balance torsion spring 33, the lock body 2 is provided with the positioning pin, one end of the balance torsion spring 33 is hooked on the positioning pin, the other end is connected to the driving member 40, the acting force of the balance torsion spring makes the driving member 40 have a tendency to rotate in the direction of driving the bolt 3 to stretch out, the acting force gradually increases in the process of stretching out the bolt 3, the total force of the two first springs 9 and the balance torsion spring 33 acting on the bolt plate 4 is unchanged all the time, the spring force of the two first springs 9 gradually decreases when the bolt 3 stretches out, and the force of the balance torsion spring 33 gradually increases, so that the bolt 3 is ensured to move in place.

The lock tongue plate 4 is further provided with a damper 34, the damper 34 is provided with a damping rod 35, one end of the damping rod 35 extends forwards from the damper 34 to be propped against the panel 1, and the damper 34 has a buffer effect on the lock tongue plate 4 in the extending process of the lock tongue 3, so that the lock tongue plate 4 moves stably, the lock tongue 3 is prevented from being collided, and a mute effect is achieved.

The lock body 2 is also provided with a safety mechanism, the safety mechanism comprises a safety block 36 and a safety spring 37, the safety block 36 is positioned at the left end of the clamping plate 21 and is rotatably arranged on the lock body 2, the clamping plate 21 is provided with a clamping point 39, the safety block 36 is provided with a poking head 38, the poking head 38 is in a V shape, the safety block 36 is rotated anticlockwise, the poking head 38 can obliquely downwards push against the clamping point 39, two ends of the safety torsion spring are respectively connected with the safety block 36 and a limit post 27 positioned at the left end of the clamping plate 21, the torsion of the safety torsion spring enables the poking head 38 to push against the clamping point 39, so that the clamping plate 21 is fixed, the left-right movement of the clamping plate is limited, and each movement of the locking plate 4 needs to move left and right of the clamping plate 21 is fixed, so that the locking plate 4 can be fixed; the safety block 36 is rotated clockwise to separate the shifting head 38 from the locking point 39, and thus the unlocking is performed.

The two ends of the lock body 2 are provided with the heaven and earth rods, when the lock tongue 3 pops up, the heaven and earth rods on the left extend leftwards, the heaven and earth rods on the right extend rightwards, and when the lock tongue 3 retracts, the heaven and earth rods retract inwards.

The working process comprises the following steps:

when the key is unlocked, the shifting fork 14 is at the closing position, the key rotates, the driving tooth 13 is driven by the gear to rotate anticlockwise, the driving tooth 13 leans against the connecting pin 43 to drive the transmission piece 40 and the transmission tooth 12 to rotate, so that the hinge plate 19 is driven to move and then the latch plate 4 is pulled, the transmission tooth 12 rotates to drive the shifting fork 14 to rotate clockwise, meanwhile, in the process of moving the driving tooth 13, the driving pin 47 on the driving tooth drives the shifting piece 15 to rotate clockwise through the driving piece 46 of the shifting piece 15, so that the latch plate 6 is driven to move inwards in the process of rotating clockwise by the shifting pin 20 on the shifting piece 15, the latch 5 is retracted, after the latch plate 4 moves in place, namely the clamping hook 23 on the latch plate 21 is clamped, the latch plate 6 moves forwards under the thrust of the second spring 11 to enable the latch 5 to pop up, in the process of moving the latch plate 6, the shifting piece 15 rotates anticlockwise through the shifting pin 20 to return, and in the process of rotating the shifting piece 15, the driving tooth 13 is driven to rotate clockwise.

When the handle is unlocked, the shifting fork 14 is at the closing station, the handle drives the square hole rotating piece 17 to rotate clockwise through square steel, the shifting fork 14 and the shifting piece 15 synchronously rotate clockwise, the shifting piece 15 drives the inclined tongue plate 6 to move inwards through the shifting pin 20, the inclined tongue 5 is retracted, the shifting fork 14 drives the transmission piece 40 to rotate anticlockwise through the transmission gear 12, the hinge plate 19 is driven to move and then pull the tongue plate 4, the lock tongue 3 is retracted, after the lock tongue plate 4 moves in place, the inclined tongue plate 6 moves forwards under the thrust of the second spring 11 to enable the inclined tongue 5 to pop out, and the shifting piece 15 rotates anticlockwise to return through the shifting pin 20 in the moving process of the inclined tongue plate 6.

When the lock is locked, the door is closed, the oblique tongue 5 is pressed to drive the oblique tongue plate 6 to move, the poking piece 15 is not moved at the moment, in the moving process of the oblique tongue plate 6, the guide plate can rotate anticlockwise under the guide action of the poking pin 20 and move inwards and rotate until the draw hook on the guide plate catches the hook 23 positioned on the right side of the guide plate, when the oblique tongue 5 loses the external force of the impact, the oblique tongue plate 6 moves towards the extending direction of the oblique tongue 5 under the action of the second spring 11, so that the hook 23 can rotate clockwise through the draw hook to separate from the bayonet catch 24, and at the moment, the lock tongue plate 4 moves towards the extending direction of the lock tongue 3 under the thrust of the first spring 9 and drives the draw-pull plate 21 to move leftwards, so that the bayonet catch 24 is separated from the locking notch 30, and the lock tongue plate 4 drives the lock tongue 3 to pop up smoothly.
