The lockset includes: a housing 1 having a receiving chamber 11 and a first bolt 21; an opening 12 which is communicated with the accommodating cavity 11 and is used for the first bolt 21 to slide in or out is formed in the shell 1; the first bolt 21 is connected with a sliding part 22 which is arranged in the accommodating cavity 11 in a sliding way, and the sliding part 22 is provided with a trigger part 23; the accommodating chamber 11 is provided with a first switch 31 located on a moving path of the trigger 23.

Thus, the first bolt 21 slides into/out of the accommodating cavity 11 through the opening 12, the first bolt 21 slides by being pulled by the sliding part 22 (optionally, in an embodiment, the sliding of the sliding part 22 is driven by a key when the key rotates the lock cylinder, the sliding of the sliding part 22 can also be driven by a motor), and in the sliding process of the sliding part 22, the trigger 23 on the sliding part 22 can trigger the first switch 31, and the triggered first switch 31 can remind a user (the first switch 31 can remind the user that the first switch 31 starts an external light or a horn reminds the user) whether the first bolt 21 is pried or not.

Specifically, in one embodiment, when the first latch bolt 21 extends out of the accommodating cavity 11 and locks the door, the first switch 31 is kept in the triggered state.

Specifically, in one embodiment, the slider 22 is driven to slide by the key cylinder 61.

Specifically, in one embodiment, the first locking tongue 21 is a latch tongue.

Specifically, in one embodiment, the first switch 31 is a microswitch.

Specifically, in one embodiment, a screw rod and a motor 632 for driving the screw rod to rotate are arranged in the accommodating cavity 11, and a sliding body 631 is arranged on the screw rod; the sliding body 631 is provided with a latch 633, the key cylinder drives the rotating member 634 to rotate and pushes the sliding member 22 to slide through the trigger 23, and the motor 632 drives the sliding body 631 to slide to insert the latch 633 into a pin hole on the rotating member 634 and brake the rotating member 634 to control the sliding of the sliding member 22.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, the sliding member 22 is a sliding rod slidably disposed in the accommodating cavity 11, and the first bolt 21 is connected to an end of the sliding rod; the sliding rod is arranged on the inner wall of the accommodating cavity 11 along the extending direction of the sliding rod in a sliding manner. Therefore, the first bolt 21 is conveniently arranged on the inner wall of the accommodating cavity 11 in a sliding manner through the sliding rod.

Specifically, in one embodiment, a U-shaped member 641 having a U-shaped groove is disposed in the accommodating cavity 11, and the sliding rod is slidably disposed in the U-shaped groove. Therefore, the sliding rod can keep the sliding direction of the sliding rod.

Specifically, in one embodiment, a cylindrical spring 642 is sleeved on the sliding rod, an annular gasket 643 is sleeved on the sliding rod, one end of the cylindrical spring 642 abuts against the first lock tongue 21, the other end of the cylindrical spring 642 abuts against the annular gasket 643, and the annular gasket 643 abuts against the U-shaped member 641. Thus, the U-shaped element 641 delimits the annular gasket 643, and the annular gasket 643 delimits the cylindrical spring 642; the stability of the cylindrical spring 642 is guaranteed.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, the trigger 23 is a ring body sleeved on the sliding rod. Therefore, the ring body is sleeved on the slide bars and is not easy to separate from the slide bars.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, a first position-limiting portion 62 and a second position-limiting portion are disposed on the sliding rod; the ring body is confined between the first and

second confinement portions

62 and 62. Thus, the ring body is limited between the first limit part 62 and the second limit part, so that the ring body maintains the relative positions of the ring body and the slide bar during the sliding process of the slide bar.

Further, referring to fig. 1 and 2, as an embodiment of the lock according to the present invention, the first position-limiting portion 62 is a welding portion welded to the sliding rod and protruding from an outer surface of the sliding rod, and/or the second position-limiting portion is a welding portion welded to the sliding rod and protruding from an outer surface of the sliding rod. Thus, it is very convenient to form the first position-limiting portion 62 or the second position-limiting portion.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, a second bolt 41 and a seat 42 are disposed on the housing 1; the seat body 42 is arranged in the accommodating cavity 11 and fixedly connected with the second bolt 41; a return spring 43 is connected between the seat 42 and the housing 1, and the seat 42 abuts against the second switch 32. As such, when the door is closed, the door frame abuts on the second latch tongue 41 and pushes the second latch tongue 41 to release the second switch 32; when the door is pried open, the second bolt 41 extends to a normal state, and the seat body 42 triggers the second switch 32; in this way, whether the door is pried open and the closed state of the door can be known through the second switch 32.

Specifically, in one embodiment, the second switch 32 may alert the user by activating an external light or speaker of the second switch 32.

Specifically, in one embodiment, the second latch tongue 41 is triangular. Thus, the second latch tongue 41 is not easily caught when contacting with the outside.

Specifically, in one embodiment, the seat body 42 is L-shaped, and the return spring 43 is sleeved on the seat body 42. So that the return spring 43 is not easily separated from the seat body 42.

Specifically, in one embodiment, the second switch 32 is a micro-switch.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, a rotation space for receiving the first bolt 21 and allowing the first bolt 21 to rotate is provided in the accommodating cavity 11. In this way, the first latch bolt 21 is rotated to adjust its orientation.

Further, referring to fig. 1 and fig. 2, as a specific embodiment of the lock provided by the present invention, the lock further includes a third switch 33, a boss 611 is disposed on a lock core 61 (the lock core 61: a structure of the lock that is engaged with the key) of the lock, and the third switch 33 is located on a rotation path of the boss 611. Thus, when the lock cylinder 61 rotates to drive the boss 611 to rotate and trigger the third switch 33, the user can know whether the lock cylinder 61 is rotated by a person.

Specifically, in one embodiment, the third switch 33 may remind the user by activating an external light or a speaker of the third switch 33.

Specifically, in one embodiment, the third switch 33 is a microswitch.

Specifically, in one embodiment, the device further includes a first arch member, one end of the first arch member is pivoted on the inner wall of the accommodating cavity 11, and the other end of the first arch member abuts against the third switch 33; the boss 611 contacts the arcuate surface of the first arch when rotating. Therefore, the boss 611 is smoothly contacted with the cambered surface of the first arch, so that the boss 611 is not easily scratched with the third switch 33 when the third switch 33 is triggered.

Further, referring to fig. 1 and 2, as an embodiment of the lock provided by the present invention, the lock further includes a fourth switch 34, where the fourth switch 34 is located on a retraction path of a main bolt (the main bolt is generally cylindrical and is inserted into an upper hole of a doorframe). Therefore, after the main bolt is retracted, the fourth switch 34 is triggered, and the user can know that the main bolt is unlocked through the fourth switch 34.

Specifically, in one embodiment, the fourth switch 34 may alert the user by activating an external light or speaker of the fourth switch 34.
