DETAILED DESCRIPTION

[0046] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0047] See also Figures 1 - 3 , shows a lock of a preferred embodiment of the utility model, comprising:

[0048] Lock housing 1;

[0049] A secondary lock tongue 2, the secondary lock tongue 2 is telescopically movably arranged on the lock housing 1, and the secondary lock tongue 2 has an extended state relative to the lock housing 1 and a retracted state hidden in the lock housing 1, and the secondary lock tongue 2 moves to switch between the extended state and the retracted state;

[0050] A linkage member 3, the linkage member 3 is connected to the auxiliary lock tongue 2, the linkage member 3 is movably arranged on the lock housing 1 along the telescopic movement direction of the auxiliary lock tongue 2, the linkage member 3 is provided with a toggle groove 31 and a first inclined surface 32, and the first inclined surface 32 is located on a side close to the opening of the toggle groove 31;

[0051] A toggle member 4, which is rotatably arranged and has a toggle portion 41, which is movably matched with the toggle groove 31 to push the linkage member 3 to reciprocate along the telescopic movement direction of the auxiliary lock tongue 2, and when the auxiliary lock tongue 2 is in the extended state, the end of the toggle portion 41 away from the toggle member 4 abuts against the first inclined surface 32 to limit the auxiliary lock tongue 2 to the extended state; and

[0052] The unlocking mechanism is arranged on the lock housing 1 , and is connected to the toggle member 4 . The unlocking mechanism is used to drive the toggle member 4 to rotate.

[0053] In the lock of the utility model, since the unlocking mechanism is connected to the toggle member 4, when the unlocking mechanism is operated to lock, the unlocking mechanism is used to drive the toggle member 4 to rotate in the opposite direction, and the toggle member 4 rotates to drive the toggle portion 41 to move in the toggle groove 31, thereby pushing the linkage member 3 to move along the extension direction of the auxiliary lock tongue 2 until the end of the toggle portion 41 away from the toggle member 4 abuts against the first inclined surface 32, so that the auxiliary lock tongue 2 is reliably restricted in the extended state, the auxiliary lock tongue 2 is locked, and the auxiliary lock tongue 2 is prevented from being retracted at will, thereby improving the locking stability of the auxiliary lock tongue 2, and the auxiliary lock tongue 2 is prevented from being retracted at will. When the lock is unlocked by operating the unlocking mechanism, the unlocking mechanism is used to drive the toggle member 4 to rotate in the forward direction. The toggle member 4 rotates to drive the toggle portion 41 to move in the toggle groove 31, thereby pushing the linkage member 3 to move along the retraction direction of the auxiliary lock tongue 2 until the auxiliary lock tongue 2 is restricted to the retracted state. Among them, since the auxiliary lock tongue 2 can be reliably maintained in the extended state under the limiting action of the end of the toggle portion 41 away from the toggle member 4 and against the first inclined surface 32, the auxiliary lock tongue 2 can be locked to prevent the auxiliary lock tongue 2 from retracting at will, thereby improving the locking stability of the auxiliary lock tongue 2.

[0054] See also Figures 2 - 3 In one embodiment, the toggle member 4 is further provided with a limiting portion 42. When the auxiliary lock tongue 2 is in an extended state, the limiting portion 42 and the end of the linkage member 3 facing away from the auxiliary lock tongue 2 abut against each other to limit the toggle member 4, so that the end of the toggle portion 41 facing away from the toggle member 4 can be reliably maintained in a state of abutting against the first inclined surface 32, which can further improve the locking stability of the auxiliary lock tongue 2.

[0055] See also Figures 2 - 3 In one embodiment, the linkage member 3 is further provided with a second inclined surface 33, the second inclined surface 33 is located on the other side of the opening close to the toggle slot 31, and the second inclined surface 33 and the first inclined surface 32 are respectively disposed on the left and right sides of the toggle slot 31 along the telescopic movement direction of the auxiliary lock tongue 2;

[0056] When the auxiliary lock tongue 2 is in the retracted state, the end of the toggle portion 41 facing away from the toggle member 4 abuts against the second inclined surface 33 to restrict the auxiliary lock tongue 2 to the retracted state, so that the auxiliary lock tongue 2 can be reliably maintained in the retracted state, thereby improving the unlocking stability of the auxiliary lock tongue 2.

[0058] A lock core 5, which is disposed on the lock housing 1 and connected to the toggle member 4, and is used to drive the toggle member 4 to rotate; and

[0059] The electric unlocking mechanism 6 is arranged on the lock housing 1. The electric unlocking structure is connected to the toggle member 4. The electric unlocking mechanism 6 is used to drive the toggle member 4 to rotate. Since the lock cylinder 5 is connected to the toggle member 4, when the lock cylinder 5 is locked by the mechanical key, the lock cylinder 5 is used to drive the toggle member 4 to rotate in the opposite direction. The toggle member 4 rotates to drive the toggle part 41 to move in the toggle groove 31, thereby pushing the linkage member 3 to move along the extension direction of the auxiliary lock tongue 2 until the end of the toggle part 41 away from the toggle member 4 abuts against the first inclined surface 32, so that the auxiliary lock tongue 2 is reliably restricted in the extended state. When the lock cylinder 5 is unlocked by the mechanical key, the lock cylinder 5 is used to drive the toggle member 4 to rotate in the opposite direction. The moving member 4 rotates forward, and the toggle member 4 rotates to drive the toggle portion 41 to move in the toggle groove 31, thereby pushing the linkage member 3 to move along the retraction direction of the auxiliary lock tongue 2 until the auxiliary lock tongue 2 is restricted to the retracted state, and mechanical locking and unlocking can be achieved; similarly, since the electric-controlled unlocking mechanism 6 is connected to the toggle member 4, when the electric-controlled unlocking mechanism 6 is operated to lock, the electric-controlled unlocking mechanism 6 is used to drive the toggle member 4 to rotate in the opposite direction, and the toggle member 4 rotates to drive the toggle portion 41 to move in the toggle groove 31, The linkage member 3 is thereby pushed to move in the extension direction of the auxiliary lock tongue 2 until the end of the toggle portion 41 away from the toggle member 4 abuts against the first inclined surface 32, so that the auxiliary lock tongue 2 is reliably restricted in the extended state, the auxiliary lock tongue 2 is locked, and the auxiliary lock tongue 2 is prevented from being retracted at will, thereby improving the locking stability of the auxiliary lock tongue 2. When the lock is unlocked by operating the electric control unlocking mechanism 6, the electric control unlocking mechanism 6 is used to drive the toggle member 4 to rotate forward, and the toggle member 4 rotates to drive the toggle portion 41 to move in the toggle groove 31. The auxiliary lock tongue 2 is moved, thereby pushing the linkage member 3 to move in the retracting direction of the auxiliary lock tongue 2 until the auxiliary lock tongue 2 is restricted in the retracted state, and electrically controlled locking and unlocking can be achieved. Whether it is locked mechanically or electrically controlled, the auxiliary lock tongue 2 can be reliably maintained in the extended state under the limiting action of the end of the toggle portion 41 away from the toggle member 4 and against the first inclined surface 32, so that the auxiliary lock tongue 2 can be locked, the auxiliary lock tongue 2 can be prevented from being retracted at will, and the locking stability of the auxiliary lock tongue 2 is improved.

[0066] A controller (not shown in the figure) is electrically connected to the motor 61 and the input module, and the controller is used to control the start of the motor 61 according to the input command of the input module. In this way, when the input command of unlocking is input through the input module, the controller can control the motor 61 to rotate in the forward direction according to the input command, and the motor 61 rotates in the forward direction to drive the second gear 62 to rotate, and the first gear 43 follows the rotation of the second gear 62 to drive the toggle part 41 to rotate, thereby pushing the linkage member 3 to move along the extension direction of the auxiliary lock tongue 2 until the end of the toggle part 41 away from the toggle member 4 abuts against the first inclined surface 32, so that the auxiliary lock tongue 2 is reliably restricted in the extended state. The electric control unlocking mechanism 6 composed of the motor 61, the second gear 62, the input module and the controller is simple and practical, with high synchronization, and can improve the unlocking sensitivity of the auxiliary lock tongue 2.
