Furthermore, a stop groove 11 is arranged on the base 1, when the bolt 5 retracts into the bolt hole 31, a first limiting end 55 on the base can fall into the stop groove 11, the stop groove 11 plays a role in positioning the bolt 5 to a first degree, and the bolt is prevented from being thrown out of the bolt hole 31 due to rotation of the door after being retracted into the bolt hole 31.
As shown in fig. 2-4, the limiting mechanism 6 includes the second rotating shaft 611 disposed on the housing, the second rotating shaft 611 is connected with the rotatable lock control plate 61, the lock control plate 61 includes the second rotating portion 612 connected to the second rotating shaft 611, the second rotating portion 612 extends towards one side to form the limiting plate 613, the front end of the limiting plate 613 is formed with the second limiting end 614 for limiting the rotation of the lock tongue 5, the second limiting end 614 abuts against the first limiting end 55, the second rotating portion 612 extends towards the other side to form the lock lever frame 615, the lock lever frame 615 is provided with the trigger portion, the base 1 is provided with the trigger, the second rotating shaft 611 is further provided with the torsion spring 7, and the torsion spring 7 makes the second limiting end 614 of the lock control plate 61 has a tendency for limiting the lock tongue 5.
In the above embodiment, the limiting mechanism 6 mainly depends on a lock control plate 61 connected to the housing through the second rotating shaft 611, the front end of the lock control plate 61 limits the first limiting end 55 of the lock tongue 5 through the second limiting end 614 on the limiting plate 613, the limiting of the second limiting end 614 on the first limiting end 55 is released at the rear end of the lock control plate 61, that is, the lock control lever rack 615, through the cooperation between the trigger part and the trigger part arranged on the base 1, so that the lock tongue 5 can retract into the lock tongue hole 31 during the opening process of the door, in addition, after the lock tongue 5 retracts into the lock tongue hole 31, the limiting plate 613 of the lock control plate 61 can press on the arc surface 53 of the lock tongue 5 to limit the lock tongue 5 and give pressure to prevent the lock tongue 5 from extending out of the lock tongue hole 31 when the door is opened, the torsion spring 7 on the second rotating shaft 611 always allows the second limiting end 614 on the lock control plate 61 to have the function of limiting the first limiting end 55 of the lock tongue 5, so that the lock control plate 61, after losing the external force, and when the lock tongue 5 is ejected out of the lock tongue hole 31, will form a limit to the first limit end 55 of the lock tongue 5 through the second limit end 614.
Specifically, as shown in fig. 5 and 6, the triggering member may be a motor 81 disposed on the base 1, the output shaft 82 of the motor 81 is connected to a cam 83 or other components, and the triggering portion is a triggering fulcrum 616 formed on the lock lever frame 615 on a side connected to the motor 81, and when the motor 81 rotates, the cam 83 on the output shaft 82 is driven to act on the triggering fulcrum 616, so that the whole lock control plate 61 rotates relative to the second rotating shaft 611, and the second limiting end 614 releases the limitation on the first limiting end 55.
In addition, in the above embodiment, since the motor 81 only needs to lift the trigger pivot 616 through the cam 83 on the output shaft 82, and does not need to overcome the mutual attraction between the magnet in the bolt 5 and the magnet in the buckle case 120, the output power required by the motor 81 is small, and the power consumption is low. It should be noted that the motor 81 is generally connected to a controller on the panel or the handle, and the motor 81 is enabled to operate by inputting a correct command.
Specifically, as shown in fig. 7 and 8, the triggering member is a key dial 84 disposed on the base 1, the triggering portion is a first inclined surface 617 disposed on the lock lever frame 615, and when the key dial 84 is turned by a key, the key dial 84 acts on the first inclined surface 617 of the lock lever frame 615 through the first triggering arm 85 thereon, so that the lock control plate 61 rotates relative to the second rotating shaft 611, and the second limiting end 614 releases the limitation on the first limiting end 55.
Specifically, as shown in fig. 9 and 10, the triggering element is a handle knob 86 disposed on the base 1, the triggering portion is a second inclined surface 618 disposed on the lock control lever frame 615, and when the handle knob 86 is rotated by the handle, the second triggering arm 87 on the handle knob 86 acts on the second inclined surface 618 on the lock control lever frame 615, so that the lock control plate 61 rotates relative to the second rotating shaft 611, and the second limiting end 614 releases the limitation on the first limiting end 55.
As shown in fig. 4, when the lock control plate 61 rotates under the action of the trigger and the second limiting end 614 releases the limitation of the first limiting end 55, the cover plate 2 is provided with a yielding groove 11, so that the second limiting end 614 of the limiting plate 613 is driven into the yielding groove 21 to give a motion path for the rotation of the first limiting end 55 of the bolt 5. It should be noted that, since the lock control plate 61 is always acted by the torsion spring 7, when the lock tongue 5 and the lock control plate 61 are in the state shown in fig. 4, the limiting plate 613 on the lock control plate 61 presses the arc surface 53 of the lock tongue 5, so that the first limiting end 55 thereof is fixed in the stop groove 11 of the base 1, and firmly presses the lock tongue 5, thereby preventing the lock tongue 5 from popping out in the state of retracting into the lock hole 31.
Further, a side of the limit plate 613 facing the arc surface 53 of the bolt 5 is also provided in an arc shape.
As shown in fig. 3 and 4, the housing is provided with a limiting rod 9, and the limiting plate 613 is provided with a limiting groove 619 matched with the limiting rod 9.
