Like this, through setting up the flexible condition of attraction mechanism 6 control spring bolt 4 in lock body 2 to the closure of control lock body 2 and hasp box 3, specifically, attraction mechanism 6 control spring bolt 4 gets into in the hasp box 3 when closing the door and window, attraction mechanism 6 control spring bolt 4 accomodate in lock body 2 when opening the door and window, and spring bolt 4 is by the restriction state of unblanking, consequently spring bolt 4 can not be touched by mistake and stretch out lock body 2, thereby makes spring bolt 4 take place to hang or scrape with people or object, produces the potential safety hazard.

Referring to fig. 2 and 3, the attraction mechanism 6 includes a first magnetic member 61 and a second magnetic member 62, where the first magnetic member 61 and the second magnetic member 62 are respectively disposed in the lock tongue 4 and the lock catch box 3, and when the lock body 2 is close to the lock catch box 3, a first attraction force is generated between the first magnetic member 61 and the second magnetic member 62.

Preferably, in the present embodiment, the side surface of the lock tongue 4 is provided with the mounting opening 411 for mounting the first magnetic member 61, and it should be noted that the mounting manner of the lock tongue 4 on the first magnetic member 61 is not limited thereto, and in other embodiments, the lock tongue may be set according to specific requirements, which is not described herein.

It should be noted that, the first magnetic member 61 and the second magnetic member 62 may be made of a permanent magnet material, or the first magnetic member 61 is made of a permanent magnet material, the second magnetic member 62 is made of a magnetic adsorption material, or the second magnetic member 62 is made of a permanent magnet material, and the first magnetic member 61 is made of a magnetic adsorption material, which is a material that can be magnetically adsorbed, such as iron, nickel, etc.; it can be understood that in the moving process of the lock tongue 4, the lock tongue 4 receives a first acting force towards the lock catch box 3 and a second acting force towards the lock body 2 at the same time, when the door and window are closed, the first acting force received by the lock tongue 4 is larger than the second acting force, so that the lock tongue 4 stretches out from the lock body 2 and enters the lock tongue 4 box.

Referring to fig. 4 and 5, the attraction mechanism 6 further includes a reset member 5 connected to the lock tongue 4, which provides a second force to the lock tongue 4 to enable the lock tongue 4 to be received in the lock body 2, wherein the second force is greater than the first force between the first magnetic member 61 and the second magnetic member 62 when the lock body 2 is far away from the lock catch box 3, and the first force is greater than the second force when the lock body 2 is close to the lock catch box 3.

Specifically, when the lock body 2 is close to the lock catch box 3, the lock tongue 4 overcomes the second acting force of the reset piece 5 and enters the lock catch box 3, and when the lock body 2 is far away from the lock catch box 3, the lock tongue 4 is driven by the reset piece 5 to retract the lock body 2. Referring to fig. 2, 3 and 7, the locker 3 includes: a locking groove 7 provided in the lock case 3; a bayonet 71 provided in the lockbox 3 and communicating with the locking slot 7 for receiving the locking bolt 4 into the locking slot 7; the lock tongue 4 has a hook-shaped locking portion 41 having a gap between inner surfaces opposite to the lock groove 7 after entering the lock groove 7, and the locking portion 41 is adapted to move along the bayonet 71 to perform locking or unlocking operation.

It should be noted that, in the present embodiment, the lock 1 has a housing 31 and an inner box 32 in the lock box 3, the second magnetic member 62 is mounted on the inner box 32, and the inner box 32 is detachably connected to the housing 31; the housing 31 is provided with a locking groove 7, the surface of the housing 31 is provided with a bayonet 71 communicated with the locking groove 7, and the locking part 41 enters the locking groove 7 from the position of the bayonet 71 and moves along the bayonet 71 so as to be engaged with or disengaged from the bayonet 71; it should be noted that, after the locking portion 41 enters the locking groove 7, there is a gap between the inner surfaces opposite to the locking groove 7, that is, the inner surfaces are not contacted with each other, so that collision and friction can not occur, and thus, impact and noise generated when the door and window are closed are reduced, and the use experience is more comfortable.

Referring to fig. 4, a limiting groove 8 is formed on the surface of the lock body 2, and when the lock body 2 is far away from the lock catch box 3, the limiting groove 8 is used for accommodating the locking portion 41.

When the lock body 2 is far away from the lock catch box 3, the lock tongue 4 is driven by the reset piece 5 to retract into the lock body 2, and the locking part 41 of the lock tongue 4 is just positioned in the limit groove 8 and is fixed and stored by the limit groove 8, so that shaking, impact prevention and scraping are avoided.

Referring to fig. 5 and 6, the lock body 2 is provided with a receiving cavity 9, and the receiving cavity 9 is provided with: the connecting piece 10 is used for configuring the lock tongue 4, and one end of the reset piece 5, which is far away from the lock tongue 4, is fixed on the connecting piece 10; a first sliding groove 91 is provided in the accommodating chamber 9 for moving the connecting piece 10 along the first sliding groove 91.

It should be noted that, when the lock body 2 is far away from the lock catch box 3, the lock tongue 4 is driven by the reset piece 5 to be stored in the connecting piece 10 in the accommodating cavity 9, and the locking portion 41 of the lock tongue 4 is stored and fixed by the limiting groove 8, so that the connecting piece 10 cannot drive the lock tongue 4 to move, when the lock body 2 is close to the lock catch box 3, the lock tongue 4 enters the lock catch box 3, so that the connecting piece 10 can move in the accommodating cavity 9 along the first sliding groove 91, thereby driving the lock tongue 4 to move in the lock catch box 3.

Referring to fig. 4 and 5, the reset element 5 is a spring, and when the reset element is in a natural state, the lock tongue 4 is accommodated in the lock body 2.

Preferably, the reset element 5 in the embodiment is a spring, when the lock body 2 approaches the lock catch box 3, the spring is in a stretched state, and the lock tongue 4 overcomes the second acting force of the spring and enters the lock catch box 3; when the lock body 2 is far away from the lock catch box 3, the spring is in a rebound state, and the lock tongue 4 is driven by the spring to retract the lock body 2, so that the lock tongue 4 is prevented from hooking or scraping with people or objects, and potential safety hazards are generated; it should be noted that, in other embodiments of the present utility model, the restoring member 5 may also be other mechanisms capable of implementing a restoring function, for example, the restoring member 5 may also be rubber or other elastic members, which may be set according to specific requirements, and will not be described herein.
