As shown in fig. 1 to 4, the present embodiment provides a lock body including a base 1, a lock tongue 2, and a driving mechanism 3; the first end of the lock tongue 2 is rotatably connected with the base 1 through a rotating shaft, the second end of the lock tongue 2 is a free end, the driving mechanism 3 is slidably connected with the base 1, the driving mechanism 3 is in transmission connection with the lock tongue 2, and the driving mechanism 3 is used for driving the lock tongue 2 to move to a first state or a second state relative to the base 1; the lock tongue 2 is in the first state, the free end of the lock tongue 2 is accommodated in the base 1, that is, the first end of the lock tongue 2 is a rotation base point, and the second end of the lock tongue 2, that is, the free end rotates relative to the rotation base point and is accommodated in the base 1. Further, in the second state of the lock tongue 2, the free end of the lock tongue 2 extends out of the base 1 in a rotating manner, and when the free end of the lock tongue 2 is subjected to external torsion, the lock tongue 2 is in a non-storable state relative to the base 1. Specifically, when the lock tongue 2 is in the second state, i.e. the lock body is in the locking state, the lock tongue 2 is in a state of being unable to rotate freely relative to the base 1 and being accommodated in the base 1, thereby avoiding that an external force (torsion force) is applied to the lock tongue 2 to reversely rotate the lock tongue 2 so as to achieve the purpose of unlocking the lock body and the door and window, and further improving the reliability of the lock body in the locking state or the safety level of the lock body and the door and window; that is, the corresponding action of the tongue 2 can only be achieved by driving the driving mechanism 3.

As shown in fig. 1 to 4, in a preferred embodiment, the driving mechanism 3 comprises a slide 4 and a guide member 5, the slide 4 is slidably connected with the base 1, further, the slide 4 can axially reciprocate relative to the base 1, the guide member 5 is fixed with the slide 4 by a bolt, and the guide member 5 is in transmission connection with the lock tongue 2. Further, a driving lever 6 is further disposed at the first end of the lock tongue 2, the driving lever 6 and the lock tongue 2 are integrally formed, and the driving lever 6 is deviated from the rotation axis of the lock tongue 2 relative to the base 1. Further, the driving lever 6 penetrates through the lock tongue 2, and both ends of the driving lever 6 protrude from the surface of the lock tongue 2, so that the lock tongue 2 can be stored or extended relative to one side of the base 1, or the lock tongue 2 can be stored or extended relative to the other side of the base 1; namely, the lock body can adapt to different installation requirements through the flexible device of the lock tongue 2 relative to the base 1. For example, in the case of a sliding door, it is necessary to install a lock body on two door leaves, one of the lock bodies needs to be installed on the right side of one door leaf, and the other lock body needs to be installed on the left side of the other door leaf, and when the position of the base of the lock body relative to the door leaf is not changed (the base rotates 180 degrees), only the installation position of the lock tongue 2 relative to the base 1 needs to be adjusted.

As shown in fig. 3 to 4, in a preferred embodiment, the guide 5 includes a body 7 and a guide groove 8 provided on the body 7, and the tip of the lever 6 is disposed in the guide groove 8 and movable along the guide groove 8, the guide groove 8 in this embodiment being substantially C-shaped or substantially arc-shaped. Further, the guiding groove 8 comprises a first limiting end 9 and a second limiting end 10, the first limiting end 9 is communicated with the second limiting end 10, and an included angle is formed between the first limiting end 9 and the second limiting end 10; further, when the lock tongue 2 is in the first state, the deflector rod 6 is positioned in the first limiting end 9; in the second state, the lock tongue 2 is located in the second limiting end 10 by the deflector rod 6. Specifically, since the guide groove 8 is substantially arc-shaped or C-shaped, when the slide 4 drives the guide member 5 to move, the guide member 5 and the deflector rod 6 cooperate with each other to rotate the lock tongue 2 relative to the base 1, and simultaneously the deflector rod 6 slides reciprocally along the guide groove 8; in the present embodiment, the rotation angle (from the housed state to the deployed state) of the tongue 2 with respect to the base 1 is 90 degrees. Further, when the lock tongue 2 is in an extended state relative to the base 1 or the lock tongue 2 rotates 90 degrees relative to the base 1, an included angle is formed between the axis of the lock tongue 2 and the axis of the base 1, and the driving lever 6 is located in the second limiting end 10 of the guiding groove; that is, when the bolt 2 is rotated, the shift lever 6 is driven to rotate, and further, when the shift lever 6 rotates along with the bolt 2, there is a short-distance and approximately C-shaped track moving up and down, the moving up and down direction can be regarded as forming an approximately vertical included angle with the axis of the base 1, and the second limiting end 10 is propped against the shift lever 6; that is, at this time, if a torsion is applied to the lock tongue 2 and the driving lever 6 is driven to move, the driving lever 6 moves in the radial direction of the base 1 or the guide 5 at this time, so that the driving lever 6 always abuts against the second limiting end 10, that is, the lock body cannot be unlocked by applying a reverse torsion to the lock tongue 2; further, the direction of the movement of the guide 5 driven by the slide 4 is along the axial direction of the base, so that the latch bolt 2 can be smoothly restrained by the guide groove 8 and driven to rotate relative to the base 1.

In a preferred embodiment, as shown in fig. 3-4, the guiding grooves 8 are provided two and symmetrical to each other, and there is at least a partial overlap between the two guiding grooves 8; providing two guide grooves 8 can help the bolt 2 to change the installation position with respect to the base 1, that is, make the bolt 2 can stretch out or accomodate from the both sides of the base 1, and then improve the suitability of the lock body. Further, the two lock bolts 2 and the guide piece 5 are arranged at intervals, the lock bolts 2 move in opposite directions, the two lock bolts 2 can improve the locking strength of the lock body, and further, when the lock body is applied to a sliding door or window, the lock bolts 2 can be hook-shaped lock bolts as shown in the figure.

As shown in fig. 4, in the preferred embodiment, the base 1 is further provided with a lock cylinder 11, the lock cylinder 11 is in transmission connection with the driving mechanism 3, and the lock cylinder 11 is used for locking the driving mechanism 3; specifically, for example, the driving mechanism is driven by a hand, and after the key cylinder is provided, the driving mechanism 3 can be locked, and at this time, the driving mechanism 3 can no longer be operated by the hand to unlock the lock body. .
