DETAILED DESCRIPTION

[0039] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0043] See also Figure 1 The embodiment of the present application provides a door lock, including a lock body and a lock panel, wherein the lock panel and the lock body are electrically connected or transmission connected. It should be noted that, in actual application, the door lock is installed on the door panel, and the door panel can rotate relative to the door frame. The door frame is provided with a lock slot that matches the door lock, and the lock tongue on the lock body can selectively extend into the lock slot or retract from the lock slot. When closing the door, the door panel rotates in a direction close to the door frame until the door lock is connected to the door frame and the lock tongue extends into the lock slot. At this time, the door panel can no longer rotate, thereby realizing the locking function; when opening the door, the door lock is separated from the door frame, the lock tongue is retracted from the lock slot, and the door panel can rotate relative to the door frame again, thereby realizing the unlocking function. If the lock panel and the lock body are transmission connected, specifically, the lock panel is provided with a lock hole connected to the lock body, the key is inserted into the lock hole, the key is transmission connected to the lock body, and the key is turned to drive the lock body to separate from the lock slot, thereby realizing the manual unlocking function; if the lock panel and the lock body are electrically connected, specifically, the lock panel is provided with a sensor, and the sensor is connected to the controller, when the sensor detects the user's fingerprint or unlocking password, the controller controls the lock body to separate from the lock slot, thereby realizing the electric unlocking function.

[0044] See also Figure 1 , for the convenience of description, Figure 1 The X direction is the clockwise direction, and the Y direction is the counterclockwise direction. The lock body includes a shell 1, a lock tongue assembly 2, a flip tongue assembly 4 and a first unlocking assembly 3. The shell 1 forms a accommodating cavity 16, and the shell 1 is provided with a first lock hole 13 and a second lock hole 14 connected to the accommodating cavity 16; the lock tongue assembly 2 can be slidably arranged along the axial direction of the first lock hole 13, and can selectively extend out of the first lock hole 13 or be retracted into the accommodating cavity 16.

[0045] Specifically, the housing 1 includes a shell 11 and a guide plate 12. The guide plate 12 is connected to a side of the shell 11 close to the door frame. The guide plate 12 is provided with a first lock hole 13 and a second lock hole 14. The guide plate 12 and the shell 11 are arranged to form a receiving space. The door frame is provided with a first lock slot opposite to the first lock hole 13. Figure 2 and Figure 3The locking tongue assembly 2 includes a first locking tongue 21 and a rotating rod 22 . The first locking tongue 21 is slidably arranged along the axial direction of the first locking hole 13 .

[0046] In one embodiment, the first locking tongue 21 is provided with a slide groove 24 along the axial direction of the first locking hole 13, and a slide column (not shown in the figure) is provided on the housing 1, which is slidably connected with the slide groove 24 through the slide column to realize the sliding of the first locking tongue 21 along the axial direction of the first locking hole 13; the first locking tongue 21 is also provided with a groove 23, and the rotating rod 22 is located in the groove 23. When the rotating rod 22 rotates, it drives the first locking tongue 21 to slide along the slide groove 24, so that the first locking tongue 21 extends out of the first locking hole 13 and extends into the first locking groove to complete the locking function, or drives the first locking tongue 21 to be retracted from the first locking groove to the accommodating chamber 16 to complete the unlocking function. It is understandable that the first locking tongue 21 can be slidably connected with the housing 1 in other ways, for example, the housing 1 is provided with a slide groove 24, and the first locking tongue 21 is slidably connected with the slide groove 24.

[0047] In one of the embodiments, the first lock tongue 21 is a square tongue, and the side surfaces of the square tongue are perpendicular to the plane where the door frame is located, which has good anti-theft performance, greatly reduces the probability of being pried open, and improves the safety performance of the door lock.

[0048] It can be understood that a torsion spring is provided between the first locking tongue 21 and the housing 1 , and the torsion spring provides auxiliary power when the first locking tongue 21 moves.

[0049] See also Figure 4 The flap assembly 4 includes a second locking tongue 41 and a limiting member 42. The second locking tongue 41 can be slidably arranged along the axial direction of the second locking hole 14, and can selectively extend out of the second locking hole 14 or be retracted into the accommodating cavity 16; the limiting member 42 is movably connected to the shell 1, and limits the second locking tongue 41 along the axial direction perpendicular to the second locking hole 14.

[0050] In this embodiment, the second locking tongue 41 is a flip tongue, which is different from other types of locking tongues. The flip tongue is a locking tongue with a rotational characteristic. When opening the door, the unlocked flip tongue can contact the door frame and flip over. The flipped flip tongue is then abutted by the door frame, pushing the flip tongue back into the accommodating cavity 16, and the door is opened. Specifically, a second lock groove corresponding to the second lock hole 14 is provided on the door frame, see Figure 5 A slope 412 is provided on one side of the flap, and a vertical surface 413 is provided on the side opposite to the slope 412. When the second locking tongue 41 is limited by the limiting member 42, the slope 412 forms a certain angle with the plane where the shell 1 is located, and the shell 1 can be arranged roughly parallel to the door frame. Therefore, a certain angle is also formed between the slope 412 and the door frame, and the vertical surface 413 is perpendicular to the door frame.

[0051] See again Figure 1 and Figure 2The first unlocking assembly 3 is rotatably connected to the housing 1, and the first unlocking assembly 3 is connected to the lock tongue assembly 2. If the first unlocking assembly 3 rotates, the first unlocking assembly 3 drives the lock tongue assembly 2 to move, and drives the limiting member 42 to separate from the second lock tongue 41, so that the second lock tongue 41 can flip along the axis direction perpendicular to the second lock hole 14. When the first unlocking assembly 3 rotates, the first unlocking assembly 3 can first drive the lock tongue assembly 2 to move, and then further drive the limiting member 42 to separate from the second lock tongue 41; the first unlocking assembly 3 can also drive the lock tongue assembly 2 to move and drive the limiting member 42 to separate from the second lock tongue 41 at the same time.

[0052] In the locked state, the first lock tongue 21 extends into the first lock slot in the door frame, the flap tongue (second lock tongue 41) extends into the second lock slot in the door frame, and the flap tongue is limited by the limiting member 42 and cannot be flipped. At this time, the vertical surface 413 of the flap tongue is perpendicular to the door frame. Even if the door is pushed, the first lock tongue 21 and the flap tongue cannot be retracted from the lock slot, thereby ensuring the safety of the door lock.

[0053] When unlocking, the first unlocking component 3 can rotate continuously, and during its rotation, it can drive the first locking tongue 21 to retract, and further drive the limiting member 42 to separate from the flap, so that the flap is in a free state. When opening the door, the user pulls the door panel to rotate in the direction away from the door frame. At this time, the vertical surface 413 on the flap abuts against the door frame, and the door frame applies a contact force to the flap. Since the flap is in a free state and has its own rotation characteristics, under the action of this contact force, the flap flips along the axial direction perpendicular to the second lock hole 14, so that the vertical surface 413 in vertical contact with the door frame becomes inclined, thereby forming a certain angle with the door frame. The user continues to pull the door panel, and the door frame can slide along the inclined vertical surface 413, and at the same time, a contact force along the axial direction of the second lock hole 14 is applied to the flap. Since the flap is slidable along the axial direction of the second lock hole 14, under the action of this contact force, the flap is retracted to the accommodating cavity 16, and the flap is separated from the door frame, completing the door opening action. In this way, the second lock tongue 41 adopts a flip tongue, which needs to be flipped when opening the door, and the flipping of the second lock tongue 41 is limited by the limit member 42 when locking, which limits the retraction of the flip tongue from the second lock groove, thereby realizing the locking function and further improving the safety of the door lock.

[0054] In one embodiment, the first unlocking assembly 3 is connected to the rotating rod 22. When unlocking is required, the first unlocking assembly 3 rotates counterclockwise to drive the rotating rod 22 to rotate counterclockwise, and the rotating rod 22 drives the first lock tongue 21 to retract to the accommodating chamber 16, thereby realizing the unlocking function of the first lock tongue 21. At the same time, the rotation of the first unlocking assembly 3 also drives the limiting member 42 to rotate, so that the limiting member 42 is separated from the second lock tongue 41, so that the second lock tongue 41, that is, the flip tongue, is in a state where it can be freely flipped, thereby realizing the unlocking function of the second lock tongue 41. Compared with the prior art, the lock body of the present application is provided with a plurality of lock tongues, and the anti-theft performance of the lock body is effectively improved through the locking effect of the plurality of lock tongues and the door frame, and the first unlocking assembly 3 can be directly connected to the lock tongue assembly 2 and the flip tongue assembly 4 respectively, and the first unlocking assembly 3 drives the rotating rod 22 and the limiting member 42 to move, thereby simultaneously unlocking the first lock tongue 21 and the second lock tongue 41, thereby eliminating the need to install other transmission structures in the lock body; the door lock using this lock body has a high anti-theft performance, and does not need to set other transmission structures, and the structure is relatively simple, saving production costs.

[0055] See also Figure 5 and Figure 6 In one embodiment, the above-mentioned stopper 42 can be rotatably connected to the housing 1, and a plug-in portion 421 is provided on the side of the stopper 42 close to the second lock tongue 41, and a slot 411 is provided on the side of the second lock tongue 41 close to the stopper 42. By rotating the stopper 42, the plug-in portion 421 is inserted into the slot 411 along the axis direction perpendicular to the second lock hole 14, and the flipping of the second lock tongue 41 is restricted, thereby realizing the locking function, or the plug-in portion 421 is separated from the slot 411, and the second lock tongue 41 can be freely flipped, thereby realizing the unlocking function. It is understandable that the stopper 42 can also be movably connected to the housing 1 in other ways, such as sliding connection with the housing 1, etc., and this application does not limit this.

[0056] In one embodiment, the above-mentioned flip tongue assembly 4 also includes a first reset member 43, which is connected to the shell body 1. The first reset member 43 is elastically connected to the limit member 42 so that the limit member 42 abuts against the second lock tongue 41. The first reset member 43 can adopt a torsion spring or a spring. When the first unlocking assembly 3 is separated from the limit member 42, under the elastic force of the first reset member 43, the limit member 42 can be restored to a locked state, that is, the limit member 42 is plugged into the second lock tongue 41 to lock the second lock tongue 41 and limit the flipping of the second lock tongue 41. In the state where no one interferes, the limit member 42 can automatically restore to the locked state through the first reset member 43, and the operation is more convenient.

[0057] See also Figure 7The flap assembly 4 also includes a guide member 44, a second reset member 45 and a push rod 46. The guide member 44 is connected to the housing 1. The guide member 44 is provided with a guide hole 441. The push rod 46 contacts the second lock tongue 41. The push rod 46 passes through the guide hole 441. The second reset member 45 is respectively in contact with the push rod 46 and the guide member 44, so that the push rod 46 pushes the second lock tongue 41 out of the second lock hole 14. In one embodiment, the second reset member 45 can be made of a spring, the guide member 44 is fixed to the shell 1, the push rod 46 is inserted into the guide hole 441 and is slidably connected to the shell 1, the guide hole 441 limits the push rod 46 so that the push rod 46 can only slide along the axial direction of the second lock hole 14, the second reset member 45 is arranged between the push rod 46 and the guide member 44, when the door is closed, the second lock tongue 41 is squeezed by the door frame and retracts into the accommodating cavity 16, the second lock tongue 41 drives the push rod 46 to move to compress the second reset member 45, when the door is closed, the second lock tongue 41 extends out of the second lock hole 14 under the elastic force of the second reset member 45, so that the second lock tongue 41 is inserted into the second lock groove in the door frame, and the automatic locking function of the second lock tongue 41 is realized without the need for other driving structures.

[0058] See also Figure 8 The first unlocking component 3 includes a rotating member 31, a driving motor 32, a first abutting portion 33 and a second abutting portion 34. The rotating member 31 is rotatably connected to the shell 1. The first abutting portion 33 and the second abutting portion 34 are arranged on the rotating member 31. The output end of the driving motor 32 is connected to the rotating member 31 and is used to drive the rotating member 31 to rotate; if the rotating member 31 rotates, the first abutting portion 33 pushes the lock tongue assembly 2 to move; the second abutting portion 34 pushes the limiting member 42 to move, so that the limiting member 42 is separated from the second lock tongue 41.

[0059] In one embodiment, a rotating shaft is provided on the shell 1, and the rotating rod 22 and the rotating member 31 are both sleeved on the rotating shaft. When unlocking is required, the driving motor 32 drives the rotating member 31 to rotate counterclockwise around the rotating shaft, driving the first abutting portion 33 to abut against the rotating rod 22, and the first abutting portion 33 pushes the rotating rod 22 to rotate counterclockwise, so that the first locking tongue 21 is retracted to the accommodating chamber 16, and at the same time the second abutting portion 34 abuts against the limiting member 42, driving the limiting member 42 to rotate, so that the limiting member 42 is separated from the second locking tongue 41, so that the second locking tongue 41 can be freely flipped, thereby realizing the unlocking function of the first locking tongue 21 and the second locking tongue 41; when locking is required, the driving motor 32 drives the rotating member 31 to rotate counterclockwise around the rotating shaft, driving the first abutting portion 33 to abut against the rotating rod 22, and the first abutting portion 33 pushes the rotating rod 22 to rotate counterclockwise, so that the first locking tongue 21 is retracted to the accommodating chamber 16, and at the same time the second abutting portion 34 abuts against the limiting member 42, driving the limiting member 42 to rotate, so that the limiting member 42 is separated from the second locking tongue 41, so that the second locking tongue 41 can be freely flipped, thereby realizing the unlocking function of the first locking tongue 21 and the second locking tongue 41; The machine 32 drives the rotating member 31 to rotate clockwise. At this time, the second abutting portion 34 moves away from the limiting member 42 and rotates toward the direction close to the rotating rod 22 until the second abutting portion 34 abuts against the rotating rod 22, driving the rotating rod 22 to rotate clockwise, so that the first locking tongue 21 extends out of the first locking hole 13, and the locking function of the first locking tongue 21 is realized; under the action of the first resetting member 43, after the second abutting portion 34 moves away from the limiting member 42, the first resetting member 43 pushes the limiting member 42 to plug with the second locking tongue 41 to lock the second locking tongue 41, and at the same time, the second resetting member 45 pushes the second locking tongue 41 to extend out of the second locking hole 14, and the locking function of the second locking tongue 41 is realized.

[0060] By setting a driving motor 32 in the lock body, the present application realizes the electric unlocking function. Specifically, the lock panel can be electrically connected to the lock body to make the door lock a smart door lock. Compared with traditional door locks, smart door locks can be unlocked through mobile phone Bluetooth, fingerprints, etc., which has better convenience and safety.

[0061] See again Figure 8 In one embodiment, the lock body further includes a circuit board 8, a first detection member 10 and a first trigger block 100, the circuit board 8 is connected to the housing 1, the first detection member 10 is connected to the circuit board 8, the first trigger block 100 is connected to the lock tongue assembly 2, and the first detection member 10 is electrically connected to the driving motor 32; wherein, when the rotating member 31 rotates, the first abutting portion 33 pushes the lock tongue assembly 2 to move, so as to drive the first trigger block 100 to trigger the first detection member 10, and the first detection member 10 is used to detect whether the lock tongue assembly 2 extends out of the first lock hole 13.

[0062] In one embodiment, see Fig. 9The first trigger block 100 is arranged on the rotating rod 22. The first trigger block 100 is divided into a forward trigger block 100B and a reverse trigger block 100A. The forward trigger block 100B and the reverse trigger block 100A are arranged on the rotating rod 22 at a certain angle. When the driving motor 32 drives the rotating member 31 to rotate, the rotating member 31 is divided into counterclockwise rotation and clockwise rotation. When the rotating member 31 rotates counterclockwise, the first abutment portion 33 pushes the rotating rod 22 to rotate counterclockwise, and the reverse trigger block 100A contacts the first detection member 10. At this time, the detection signal of the first detection member 10 is that the first lock tongue 21 is retracted to the accommodating chamber 16, which is an unlocking signal; when the rotating member 31 rotates clockwise, the second abutment portion 34 pushes the rotating rod 22 to rotate clockwise, and the forward trigger block 100B contacts the first detection member 10. At this time, the detection signal of the first detection member 10 is that the first lock tongue 21 extends out of the first lock hole 13, which is a locking signal. The first detection member 10 distinguishes the direction signals of counterclockwise triggering and clockwise triggering, thereby detecting whether the door lock is in a locked state or an unlocked state.

[0063] See also Figure 8 and Fig.10 In one embodiment, the lock body further includes a second detecting member 20 and a second trigger block 200, the second detecting member 20 is connected to the circuit board 8, the second trigger block 200 is connected to the rotating member 31, and the second detecting member 20 is electrically connected to the driving motor 32; if the first detecting member 10 is triggered, the driving motor 32 drives the rotating member 31 to rotate, and the rotating member 31 drives the second trigger block 200 to move, so that the second trigger block 200 triggers the second detecting member 20, and the second detecting member 20 is used to detect the reset of the driving motor 32.

[0064] In practical applications, in order to facilitate the driving motor 32 to drive the rotating member 31 to rotate, and to ensure that the time for each unlocking or locking is the same, after the driving motor 32 drives the rotating member 31 to complete a task, such as unlocking or locking, the driving motor 32 needs to be reset so that the driving motor 32 drives the rotating member 31 to rotate to the initial state, so as to ensure that the initial position of the rotating member 31 is the same each time the unlocking or locking is completed. The present application sets a second detection member 20. When the first detection member 10 is triggered, that is, the driving motor 32 drives the rotating member 31 to complete the unlocking or locking work, here taking the unlocking work as an example, when the driving motor 32 drives the rotating member 31 to rotate counterclockwise to drive the reverse trigger block 100A to trigger the first detection member 10, after the first detection member 10 is triggered, the first detection member 10 detects the unlocking signal, and then the driving motor 32 drives the rotating member 31 to rotate clockwise until the second trigger block 200 triggers the second detection member 20, indicating that the rotating member 31 is restored to the initial state, the driving motor 32 stops running, and the reset function is completed.

[0065] See again Figure 7In one embodiment, the lock body also includes a third detection member 30, which is connected to the circuit board 8; if the second lock tongue 41 retracts into the accommodating cavity 16, the flap assembly 4 triggers the third detection member 30, and the third detection member 30 is used to detect whether the second lock tongue 41 extends out of the second lock hole 14.

[0066] Specifically, one end of the push rod 46 away from the second lock tongue 41 is bent in a step-like shape toward the direction close to the third detection member 30. On the one hand, it can avoid the position of the drive motor 32, and on the other hand, it is convenient to trigger the third detection member 30. When the second lock tongue 41 is retracted to the accommodating chamber 16, the second lock tongue 41 drives the push rod 46 to move toward the direction close to the third detection member 30. When the second lock tongue 41 is fully retracted to the accommodating chamber 16, the push rod 46 contacts the third detection member 30 to trigger the third detection member 30. The third detection member 30 detects that the second lock tongue 41 is retracted to the accommodating chamber 16, that is, the second lock tongue 41 is in an unlocked state; when the second lock tongue 41 extends out of the second lock hole 14 under the restoring force of the second reset member 45, the push rod 46 is separated from the third detection member 30, and the third detection member 30 is in an untriggered state, so the third detection member 30 has no detection signal. That is to say, the third detection member 30 is triggered only when the second locking tongue 41 is retracted into the accommodating cavity 16 . Thus, whether the second locking tongue 41 is in the unlocked state can be determined by whether the third detection member 30 is triggered.

[0067] The first detection member 10 , the second detection member 20 and the third detection member 30 are all arranged on the circuit board 8 , so that the internal layout of the lock body is more compact and the design space is saved.

[0068] See again Figure 2 In one embodiment, the lock body further includes a third lock tongue 7 and a fourth detection member 40. The shell 1 is provided with a third lock hole 15. The third lock tongue 7 is slidably arranged along the axial direction of the third lock hole 15. The fourth detection member 40 is connected to the shell 1 and is electrically connected to the drive motor 32. If the third lock tongue 7 slides, the third lock tongue 7 triggers the fourth detection member 40. The fourth detection member 40 is used to detect whether the third lock tongue 7 extends out of the third lock hole 15.

[0069] In this embodiment, the third lock tongue 7 can be a triangular tongue, and the opposite sides of the triangular tongue are provided with inclined surfaces respectively. The end of the triangular tongue close to the fourth detection member 40 is connected to a trigger rod. When closing the door, the door panel rotates in the direction close to the door frame, and one of the inclined surfaces of the triangular tongue abuts against the door frame. The door frame applies an abutting force to the triangular tongue, so that the triangular tongue retracts to the accommodating cavity 16. At this time, the trigger rod moves in the direction close to the fourth detection member 40. Since the door frame does not have a lock slot for the third lock tongue 7 to extend into, after the door is closed, the third lock tongue 7 is still pressed by the door frame and is always in a state of being retracted to the accommodating cavity 16. At this time, the trigger rod maintains a state of contact with the fourth detection member 40 to trigger the fourth detection member 40. In this way, when the fourth detection member 40 detects that the third lock tongue 7 is retracted to the accommodating cavity 16, the door panel and the door frame are in a closed state, indicating that the door lock needs to be locked to prevent outsiders from opening the door and entering the room. Therefore, the fourth detection member 40 is electrically connected to the drive motor 32. When the fourth detection member 40 is triggered, the drive motor 32 is controlled by the controller to run, driving the rotating member 31 to rotate counterclockwise, thereby realizing the automatic locking function.

[0070] It is understandable that a return spring is also provided between the third lock tongue 7 and the housing 1 , and when the door panel is away from the door frame, the return spring pushes the third lock tongue 7 to extend out of the third lock hole 15 .

[0071] See also Figure 8 and Fig.11 In some embodiments, a manual unlocking function is also provided, and the lock body further includes a second unlocking member 5, which is rotatably connected to the housing 1, and is provided with a third abutting portion 51 and a fourth abutting portion 52. If the second unlocking member 5 rotates, the third abutting portion 51 drives the lock tongue assembly 2 to move, and the fourth abutting portion 52 drives the limiting member 42 to move, so that the limiting member 42 is separated from the second lock tongue 41, and the second lock tongue 41 can be turned over along the axis direction perpendicular to the second lock hole 14.

[0072] The second unlocking member 5 is provided with an arc-shaped rotation groove 53, and the housing 1 is provided with a fixed column 17, which is inserted into the rotation groove 53. The second unlocking member 5 can rotate relative to the fixed column 17. The second unlocking member 5 is also provided with a hole groove 54 for inserting a key. When the key is inserted into the hole groove 54, the key is turned, and the key drives the second unlocking member 5 to rotate around the fixed column 17, so that the third abutting portion 51 drives the rotating rod 22 to rotate counterclockwise, so that the rotating rod 22 drives the first lock tongue 21 to retract to the accommodating chamber 16, and the unlocking function of the first lock tongue 21 is realized; at the same time, the fourth abutting portion 52 abuts against the limiting member 42, drives the limiting member 42 to rotate, so that the limiting member 42 is separated from the second lock tongue 41, and the second lock tongue 41 can be freely turned over, and the unlocking function of the second lock tongue 41 is realized. It should be noted that a reset spring is provided between the second unlocking member 5 and the housing 1. After unlocking, the key is taken out, and the reset spring drives the second unlocking member 5 to return to the initial state, which is convenient for the next unlocking. By setting the manual unlocking function, it is possible to avoid the situation where the user is unable to open the door when the drive motor 32 is out of power or fails. Manual unlocking can be used as an emergency measure to improve the practicality of the door lock.

[0073] In one embodiment, the lock body further includes a spacer 6, which is disposed between the flap assembly 4 and the shell 1. Specifically, the spacer 6 is disposed between the second lock tongue 41 and the third lock tongue 7 and the guide plate 12. The spacer 6 is made of plastic to reduce the noise generated by the collision between the second lock tongue 41 and the third lock tongue 7.

[0074] Different from the prior art, the present application provides a door lock and its lock body, the lock body including a shell 1, a lock tongue assembly 2, a flip tongue assembly 4 and a first unlocking assembly 3, the lock tongue assembly 2 including a first lock tongue 21 and a rotating rod 22, the flip tongue assembly 4 including a second lock tongue 41 and a limiting member 42, when unlocking is required, the first unlocking assembly 3 rotates to drive the rotating rod 22 to move, so that the first lock tongue 21 can be retracted from the first lock hole 13 to the accommodating chamber 16, thereby realizing the unlocking function of the first lock tongue 21; the rotation of the first unlocking assembly 3 can also drive the limiting member 42 to move, so that the limiting member 42 is separated from the second lock tongue 41, so that the second lock tongue 41 is in a free flipping state, and then the second lock tongue 41 can be flipped and retracted from the second lock hole 14 to the accommodating chamber 16 when the door is open, thereby realizing the unlocking function of the second lock tongue 41. Compared with the prior art, the lock body of the present application is provided with multiple lock tongues, and the locking effect of the multiple lock tongues and the door frame effectively improves the anti-theft performance of the lock body, and the first unlocking component 3 can be directly connected to the lock tongue component 2 and the flip tongue component 4 respectively, and the first unlocking component 3 drives the rotating rod 22 and the limit member 42 to move, and the first lock tongue 21 and the second lock tongue 41 are unlocked at the same time, eliminating the need to install other transmission structures in the lock body; the door lock using this lock body has a higher anti-theft performance, and does not need to set up other transmission structures, the structure is simpler, and the production cost is saved.

[0075] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
