If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Some existing door locks can be applied to two-way doors, and include a lock base 100 and a latch bolt assembly 200. The latch bolt assembly 200 includes a connecting member 210 and a latch bolt body 220. The latch bolt body 220 has a first abutting top surface 221 and a second abutting top surface 222 arranged at an acute angle. The latch bolt body 220 can swing relative to the connecting member 210, and the latch bolt assembly 200 can be extended relative to the lock base 100, so that the latch bolt body 220 extends out or retracts into the lock base 100. When such a door lock is installed on a two-way door, when the two-way door rotates forward to close, the door frame abuts against the first abutting top surface 221 of the latch bolt body 220, so that the latch bolt body 220 swings to the first position, and the first abutting top surface 221 is inclined relative to the extension direction of the latch bolt assembly 200. The door frame presses the latch bolt assembly 200 into the lock base 100 through the first abutting top surface 221, and then the latch bolt assembly 200 pops out and inserts into the latch bolt groove of the door frame to achieve door locking. When the two-way door rotates in the opposite direction to close, the door frame abuts against the second top surface 222 of the inclined tongue body 220, so that the inclined tongue body 220 swings to the second position. The second top surface 222 is inclined relative to the extension and retraction direction of the inclined tongue assembly 200. The door frame presses the inclined tongue assembly 200 into the lock seat 100 through the second top surface, and then the inclined tongue assembly 200 pops out and is inserted into the inclined tongue groove of the door frame to lock the door.

[0039] However, after the inclined tongue assembly 200 of the above-mentioned door lock is inserted into the inclined tongue groove of the door frame, the inclined tongue body 220 can still rotate relative to the connecting piece 210. Criminals may push the first abutting surface 221 or the second abutting surface 222 by inserting a card in the door gap, so that the inclined tongue assembly 200 is retracted into the lock seat 100 and the door lock is opened, which makes the door lock less secure. A one-way door requires that the inclined tongue body 220 cannot swing relative to the connecting piece 210, which also makes the above-mentioned door lock difficult to apply to a one-way door, and the applicability of the above-mentioned door lock is insufficient.

[0040] Reference Figures 1 to 6, which is a door lock with good applicability according to an embodiment of the utility model, includes a lock seat 100, a latch bolt assembly 200 and a locking mechanism 300. The lock base 100 is provided with a first clearance hole; the oblique tongue assembly 200 includes a connecting member 210 and an oblique tongue body 220, the oblique tongue body 220 is movably arranged on the connecting member 210 and can swing relative to the connecting member 210, the oblique tongue assembly 200 is telescopically arranged on the lock base 100 along the hole axis of the first clearance hole and can make the oblique tongue body 220 extend or retract into the lock base 100, the oblique tongue body 220 has a first abutting top surface 221 and a second abutting top surface 222 arranged at an acute angle, when the first abutting top surface 221 is pressed, the oblique tongue body 220 can swing to a first position, in the first position, the first abutting top surface 221 is inclined relative to the hole axis of the first clearance hole; when the second abutting top surface 222 is pressed, the oblique tongue body 220 can swing to a second position, in the second position, the second abutting top surface 222 is inclined relative to the hole axis of the first clearance hole; the locking mechanism 300 is arranged on the lock base 100 and can lock or unlock the position of the oblique tongue body 220 relative to the connecting member 210.

[0041] When the door lock is installed on a two-way door, before the two-way door is closed, the locking mechanism 300 unlocks the position of the inclined bolt body 220 relative to the connecting member 210, and the two-way door can be closed and locked in the forward or reverse direction; when the two-way door is closed and the inclined bolt body 220 is inserted into the inclined bolt groove of the door frame, the locking mechanism 300 can lock the position of the inclined bolt body 220 relative to the connecting member 210, so that the inclined bolt body 220 cannot swing. At this time, it is difficult to press the inclined bolt body 220 into the lock seat 100 by illegal means from the outside, so that the safety of the door lock is better; when the door lock is suitable for a one-way door, the locking mechanism 300 can be used to keep the locking position of the inclined bolt body 220 relative to the connecting member 210, so that the inclined bolt body 220 cannot swing. At this time, the door lock can only close and lock the door in one direction, which is the same as the function of a conventional door lock. The door lock can be suitable for one-way doors and two-way doors through the locking mechanism 300, so the safety and applicability of the door lock are relatively good.

[0042] Specifically, the oblique tongue assembly 200 is slidably connected to the lock seat 100 through a slider and a slide groove structure, for example, the connecting member 210 is provided with a slider, the lock seat 100 is provided with a slide groove, and the slider is slidably connected to the slide groove, so that the oblique tongue assembly 200 can be slidably connected to the lock seat 100; or a slide groove is provided on the connecting member 210, and a slider is provided on the lock seat 100, and the slider is slidably connected to the slide groove, so that the oblique tongue assembly 200 can be slidably connected to the lock seat 100. It is conceivable that the oblique tongue assembly 200 can also be telescopically movable relative to the lock seat 100 through a guide column and guide sleeve structure, for example, the lock seat 100 is provided with a guide column, the connecting member 210 is provided with a guide sleeve, and the guide column is inserted into the guide sleeve; or the lock seat 100 is provided with a guide sleeve, and the connecting member 210 is provided with a guide column, and the guide column is inserted into the guide sleeve.

[0043] Specifically, the connecting member 210 is provided with an arc-shaped groove, the oblique tongue body 220 is provided with an arc-shaped protrusion, the oblique tongue body 220 is penetrated in the first clearance hole, and the arc-shaped protrusion is adapted to the arc-shaped groove, so that the oblique tongue body 220 can swing relative to the connecting member 210. It is conceivable that the oblique tongue body 220 can also be pivotally connected to the connecting member 210, so that the oblique tongue body 220 can swing relative to the connecting member 210.

[0044] In the embodiment, the locking mechanism 300 includes a reversing member 310, the reversing member 310 is provided with a limiting portion 311, the oblique tongue body 220 is provided with a limiting matching portion 223, the reversing member 310 is movably arranged on the lock seat 100 and has a locking position and an unlocking position, in which the limiting portion 311 is connected to the limiting matching portion 223; in the unlocking position, the limiting portion 311 is separated from the limiting matching portion 223. When the reversing member 310 moves to the locking position, the limiting portion 311 is connected to the limiting matching portion 223 to limit the swing of the oblique tongue body 220; when the reversing member 310 moves to the unlocking position, the limiting portion 311 is separated from the limiting matching portion 223, at which time the reversing member 310 does not limit the rotation of the oblique tongue body 220, and the oblique tongue body 220 can swing relative to the connecting member 210. The above-mentioned locking mechanism 300 has a simple structure and realizes the function of locking or unlocking the oblique tongue body 220.

[0045] In the embodiment, an electric drive assembly 400 is further included, which is disposed on the lock seat 100 and can drive the reversing member 310 to move from the locked position to the unlocked position. The electric drive assembly 400 drives the reversing member 310 to move from the locked position to the unlocked position, which facilitates the automatic control of the door lock and improves the intelligence of the door lock.

[0046] In the embodiment, the commutator 310 is rotatably arranged on the lock seat 100; the limiting matching part 223 is a limiting rod, the limiting part 311 is a limiting groove, the commutator 310 includes a rotating block 312 and a driving arm 313, the rotating block 312 is rotatably connected to the lock seat 100, one end of the limiting rod is connected to the rotating block 312, one end of the driving arm 313 is connected to the rotating block 312, and the electric drive assembly 400 can push the driving arm 313. When the driving arm 313 is pushed, the driving commutator 310 is driven to rotate, so that the limiting part 311 is separated from the limiting matching part 223, so that the locking mechanism 300 unlocks the position of the oblique tongue body 220, and the structure is simple and easy to implement. Specifically, the commutator 310 is also provided with a rotating shaft hole, and the lock seat 100 is provided with a rotating shaft, and the rotating shaft is penetrated through the rotating shaft hole, so that the commutator 310 is rotatably arranged on the lock seat 100. It is conceivable that a rotating shaft may be provided on the reversing member 310 , a rotating hole may be provided on the lock seat 100 , and the rotating shaft may be rotatably provided in the rotating shaft hole, so that the reversing member 310 may be rotatably provided in the lock seat 100 .

[0047] Specifically, when the limiting rod is in the locked position and connected to the limiting groove, the reversing member 310 is slidably connected to the oblique tongue body 220, and the extension direction of the limiting groove is the same as the telescopic direction of the oblique tongue assembly 200, which facilitates the telescopic movement of the oblique tongue assembly 200. When the limiting rod is in the locked position, only the swing of the oblique tongue body 220 relative to the connecting member 210 is restricted, and the telescopic movement of the oblique tongue assembly 200 is not restricted. It is conceivable that the limiting portion 311 and the limiting matching portion 223 can also be other structures, for example, the limiting portion 311 is a limiting rod, and the limiting matching portion 223 is a limiting groove.

[0048] In the embodiment, the electric drive assembly 400 includes a motor 410 and a driving gear 420. A push block 421 is provided on one side of the driving gear 420. The push block 421 is opposite to the driving arm 313. When the driving gear 420 rotates, the push block 421 moves toward or away from the driving arm 313, and the motor 410 can drive the driving gear 420 to rotate. When the motor 410 drives the driving gear 420 to rotate, when the push block 421 on the driving gear 420 moves toward the driving arm 313, the driving arm 313 can be pushed to make the reversing member 310 switch from the locked position to the unlocked position, so that the reversing member 310 is separated from the oblique tongue body 220, and the oblique tongue body 220 can rotate relative to the connecting member 210. When the driving gear 420 rotates until the push block 421 is away from the driving arm 313, the reversing member 310 can be allowed to reset to the locked position. The above electric drive assembly 400 has a simple structure and is easy to implement. Specifically, the motor 410 drives the driving gear 420 to rotate via the transmission gear set 430, the output shaft of the motor 410 is connected to one of the transmission gears, and the transmission gear set 430 meshes with the driving gear 420 to drive the driving gear 420 to rotate. It is conceivable that the output shaft of the motor 410 can also be directly connected to the driving gear 420 to drive the driving gear 420 to rotate.

[0049] It is conceivable that the electric drive assembly 400 can also push the drive arm 313 of the commutator 310 through other structures. For example, the electric drive assembly 400 includes an electric push rod, which can push the drive arm 313 of the commutator 310 to rotate the commutator 310.

[0050] In an embodiment, the locking mechanism 300 further includes a reversing reset member 320, which is disposed between the lock seat 100 and the reversing member 310 and is used to drive the reversing member 310 to move from the unlocking position to the locking position. The reversing reset member 320 is provided to facilitate the reversing member 310 to automatically reset to the locking position. Specifically, the reversing reset member 320 is a torsion spring, one end of which is connected to the limit rod of the reversing member 310, and the other end of which is connected to the lock seat 100, driving the reversing member 310 to reset and rotate. It is conceivable that the reversing reset member 320 can also be a spring, one end of which is connected to the driving arm 313 of the reversing member 310, and the other end of which is connected to the lock seat 100, driving the reversing member 310 to reset and rotate. When the reversing member 310 rotates to the unlocking position, the spring is compressed, and when the spring recovers, it pushes the reversing member 310 to rotate to the locking position.

[0051] It is conceivable that the electric drive component 400 can also be used to drive the reversing member 310 to move from the unlocked position to the locked position, and at this time, the reversing member 310 can be driven from the locked position to the unlocked position by the reversing reset member 320; or the electric drive component 400 can be used to directly drive the reversing member 310 from the unlocked position to the locked position, and the reversing member 310 can also be driven from the locked position to the unlocked position.

[0052] It is conceivable that the reversing member 310 can also be slidably connected to the lock base 100, and the limiting portion 311 is connected or separated from the limiting matching portion 223 by sliding. For example, the reversing member 310 is provided with a slider, the lock base 100 is provided with a slide groove, the slider is slidably connected to the slide groove, so that the reversing member 310 can slide relative to the lock base 100, and the limiting portion 311 is connected or separated from the limiting matching portion 223 by sliding close to or away from the oblique tongue body 220; or the reversing member 310 is provided with a guide sleeve, the lock base 100 is provided with a guide column, and the guide sleeve is sleeved on the guide column, so that the reversing member 310 can slide close to or away from the oblique tongue body 220 relative to the lock base 100. In this embodiment, the electric drive component 400 can adopt a structure of a motor 410, a transmission gear set 430 and a driving gear 420. The push block 421 of the driving gear 420 can push the reversing member 310 to move, and cooperate with the spring to drive the reversing member 310 to reset; or the electric drive component 400 can adopt an electric push rod to directly drive the reversing member 310 to move.

[0053] It is conceivable that the locking mechanism 300 can also be other structures. For example, the locking mechanism 300 includes a pin and an electric push rod. The electric push rod is connected to the connecting member 210. The connecting member 210 is provided with a pin hole. The inclined tongue body 220 is provided with a pin hole. The electric push rod can drive the pin to be inserted into the two pin holes, or to be disengaged from one of the pin holes, so as to lock or unlock the position of the inclined tongue body 220 relative to the connecting member 210.

[0054] In the embodiment, a tongue piece 500 is further included. The tongue piece 500 is telescopically arranged on the lock seat 100 and can extend or retract one end of the tongue piece 500. The telescopic direction of the tongue piece 500 is parallel to the telescopic direction of the oblique tongue assembly 200. The electric drive assembly 400 can drive the tongue piece 500 to telescopically move. In order to improve the safety, the door lock usually has a tongue piece 500. When locking the door, the tongue of the door lock will be inserted into the tongue hole of the door frame. The electric drive assembly 400 can drive the reversing member 310 to move and can also drive the tongue piece 500 to telescope. While improving the safety, it simplifies the structure of the door lock and reduces the production cost of the door lock.

[0055] Specifically, the lock seat 100 is provided with a second easing hole, the square tongue is slidably connected to the second easing hole, and the hole axis of the second easing hole is parallel to the hole axis of the first easing hole.

[0056] In the embodiment, a square tongue thumbwheel 600 is further included, the square tongue thumbwheel 600 is pivotally connected to the lock seat 100 and the rotation axis is perpendicular to the extension direction of the square tongue member 500, the square tongue thumbwheel 600 is provided with a lever 610, the square tongue member 500 is provided with a lever 610 receiving groove 510, one end of the lever 610 is received in the lever 610 receiving groove 510, and the electric drive assembly 400 can drive the square tongue thumbwheel 600 to rotate. By driving the square tongue thumbwheel 600 to rotate, when the square tongue thumbwheel 600 rotates, the lever 610 moves the groove wall of the lever 610 receiving groove 510 to make the square tongue extend and retract, and the structure is simple and easy to implement.

[0057] Specifically, the motor 410 of the electric drive assembly 400 drives the tongue-shaped thumbwheel 600 to rotate through the transmission gear set 430 and the driving gear 420. It is conceivable that the electric drive assembly 400 can also be a motor 410 driving the tongue-shaped thumbwheel 600 to rotate through the transmission gear set 430; or the output shaft of the motor 410 is connected to the tongue-shaped thumbwheel 600 to drive the tongue-shaped thumbwheel 600 to rotate.

[0058] It is conceivable that the electric drive assembly 400 can also drive the square tongue piece 500 to extend and retract in other ways. For example, the electric drive assembly 400 is provided with an electric push rod, and the square tongue piece 500 is connected to the electric push rod to drive the square tongue piece 500 to extend and retract.

[0059] In the embodiment, a commutation sensor 700 and a control module 800 are further included. The commutation sensor 700 and the control module 800 are arranged on the lock seat 100. The commutation sensor 700 is electrically connected to the control module 800. The control module 800 is electrically connected to the electric drive assembly 400. The commutation sensor 700 is used to detect the position of the commutation member 310. Specifically, the control module 800 is a circuit board, and the commutation sensor 700 is a press sensor. The button of the press sensor is opposite to the drive arm 313 of the commutation member 310. When the commutation member 310 rotates to the unlocking position, the drive arm 313 presses the press sensor; when the commutation member 310 rotates to the locking position, the drive arm 313 releases the press sensor, thereby knowing the position of the commutation member 310. The press sensor can output an electrical signal to the control module 800, so that the control module 800 can control the operation of the electric drive assembly 400.

[0060] It is conceivable that the commutation sensor 700 may also be a photoelectric sensor to detect the position of the commutation member 310 ; the control module 800 may also be a structure having a control circuit such as a PLC or a single-chip microcomputer.

[0061] In the embodiment, it also includes an extended reset member 900, the inclined tongue body 220 is provided with a reset surface 224, the lock seat 100 is provided with a mating surface 110, the inclined tongue body 220 is in the first position, the reset surface 224 is parallel to the mating surface 110, the inclined tongue body 220 is in the second position, the reset surface 224 is inclined relative to the mating surface 110, the extended reset member 900 is arranged between the inclined tongue assembly 200 and the lock seat 100, and the extended reset member 900 is used to drive the inclined tongue assembly 200 to extend outward and make the reset surface 224 abut against the mating surface 110. An extending reset member 900 is provided, and when the inclined tongue body 220 is retracted into the lock seat 100, the inclined tongue body 220 can be driven to automatically extend outward; and when the inclined tongue body 220 extends outward, the extending reset member 900 will drive the inclined tongue body 220 to automatically rotate until the reset surface 224 is parallel to and abuts against the matching surface 110, so that the inclined tongue body 220 will automatically reset to the first position when extended, and at this time the locking mechanism 300 can lock the position of the inclined tongue body 220.

[0062] Specifically, the extending reset member 900 is a spring, one end of which abuts against the lock seat 100, and the other end of which abuts against the latch bolt assembly 200. It is conceivable that the extending reset member 900 can also be an electric push rod, which drives the latch bolt assembly 200 to extend.

[0063] Specifically, when the latch body 220 is in the first position, the extension direction of the limit groove is substantially the same as the extension direction of the limit rod. When the latch body 220 is in the second position, the limit groove is inclined relative to the limit rod, so that the limit rod cannot be accommodated in the limit groove. In this embodiment, the locking mechanism 300 can only lock the swing of the latch body 220 in the first position.

[0064] Specifically, when the inclined tongue body 220 is in the first position relative to the connecting member 210, the reversing member 310 of the locking mechanism 300 can limit the swing of the inclined tongue body 220. It is understandable that in some embodiments, the reversing member 310 of the locking mechanism 300 can also limit the swing of the inclined tongue body 220 in the first position and the second position respectively. It is conceivable that the inclined tongue body 220 can also be provided with two limiting grooves, when the inclined tongue body 220 is in the first position, the extension direction of one of the limiting grooves is substantially the same as the extension direction of the limiting rod, at this time, the locking mechanism 300 can lock or unlock the swing of the inclined tongue body 220 relative to the connecting member 210; when the inclined tongue body 220 is in the second position, the extension direction of the other limiting groove is substantially the same as the extension direction of the limiting rod, at this time, the locking mechanism 300 can lock or unlock the swing of the inclined tongue body 220 relative to the connecting member 210. The two limiting grooves enable the inclined tongue body 220 to be locked or unlocked to swing relative to the connecting member 210 at both the first position and the second position, which has a simple structure and is more convenient to use.
