Description

Technical Field

[0001] The present invention relates to the technical field of door locks, and in particular to a convenient magnetic lock. Background Art

[0002] Door locks are essential anti-theft tools in our daily lives. Currently, commonly used magnetic door locks can be accidentally locked while open. If a person leaves the house briefly and the door is blown shut against the doorframe by the wind, the magnet on the doorframe will pull the lock tongue out of the magnetic door lock, causing the door to lock after it was accidentally closed. This can lock people out of the house when no one is inside, and they cannot unlock the door without their key, causing significant inconvenience. Summary of the Invention

[0003] The purpose of the present invention is to provide a convenient magnetic lock to solve the problem in the prior art that the magnetic door lock is easily locked when the door is closed after being locked in the open state. The convenient magnetic lock of the present invention can make the door lock unable to lock when the door is open or unable to close after being locked, thereby avoiding the situation where the door cannot be opened after being locked by mistake.

[0004] The present invention provides a convenient magnetic lock, comprising a lock housing, a lock tongue assembly and a locking slide arranged in the lock housing.

[0005] The lock tongue assembly is connected to a positioning piece, and when the door is in the open state, the lock tongue assembly is connected to the lock housing through the positioning piece so as to be retracted into the lock housing;

[0006] The locking slider cooperates with the lock tongue assembly so that when the lock tongue assembly is retracted into the lock housing, the lock tongue assembly is limited by the locking slider in the locked state and cannot extend out of the lock housing, or the locking slider is limited by the lock tongue assembly and cannot be locked.

[0007] As a preferred embodiment of the present invention, a locking paddle, a first lock tongue paddle and a second lock tongue paddle are further provided in the lock housing, wherein the first lock tongue paddle and the second lock tongue paddle are respectively abutted against the inner and outer sides of the locking paddle and are relatively rotatably connected, and the clockwise rotation of the first lock tongue paddle and the second lock tongue paddle can drive the lock tongue assembly to slide to the right side of the lock housing, and the rotation of the first lock tongue paddle can drive the locking paddle to rotate in the same direction;

[0008] The locking paddle is cooperatively connected with the locking slider. The counterclockwise rotation of the locking paddle can drive the locking slider to slide and cause the locking slider to restrict the second lock tongue paddle from rotating clockwise to achieve a locked state. The clockwise rotation of the locking paddle can drive the locking slider to release the restriction on the second lock tongue paddle to achieve an unlocked state.

[0009] As a preferred solution of the present invention, a limit hook is provided at the right end of the lock tongue assembly, and a stop portion is provided on the locking slider. When the lock tongue assembly is retracted in the lock housing and the locking slider is in a locked state, the stop portion is stuck on the left side of the limit hook to prevent the lock tongue assembly from sliding to the left and extending out of the lock housing.

[0010] As a preferred solution of the present invention, a limiting portion is provided on the lower side of the lock tongue assembly, and a stop portion is provided on the locking slider. When the lock tongue assembly is retracted in the lock housing, the limiting portion is stuck on the upper side of the stop portion to prevent the locking slider from performing a locking movement.

[0011] As a preferred solution of the present invention, a rotation stop portion is provided on the lower side of the lock tongue assembly, and a rotation card is provided on the circumferential side of the locking paddle. When the lock tongue assembly is retracted in the lock housing, the rotation stop portion is stuck on the upper side of the rotation card to prevent the locking paddle from rotating counterclockwise and at the same time prevent it from driving the locking slider to perform a locking movement.

[0012] As a preferred solution of the present invention, a first linkage member is provided on the locking peach, which protrudes from the inner side of the locking peach and is clamped on the first lock tongue peach, so that the rotation of the first lock tongue peach can drive the locking peach to rotate in the same direction.

[0013] As a preferred solution of the present invention, a second linkage member is provided on the locking slider, and the second linkage member is protruding from the outer side of the locking slider and can be clamped on the second lock tongue to limit the clockwise rotation of the second lock tongue.

[0014] As a preferred solution of the present invention, the first lock tongue paddle includes a first linkage part connected to the inner door handle, a first toggle part cooperating with the lock tongue assembly, and an unlocking part cooperating with the first linkage part. The first linkage part is a circular structure, and the first toggle part and the unlocking part are arranged at intervals on the circumference of the first linkage part. A locking part cooperating with the first linkage part is provided at one end of the first toggle part close to the first linkage part. The locking part and the unlocking part are arranged opposite to each other, and the first linkage part extends between the locking part and the unlocking part.

[0015] As a preferred solution of the present invention, the second lock tongue paddle includes a second linkage part for cooperating with the door handle outside, a second toggle part cooperating with the lock tongue assembly, and a locking part cooperating with the second linkage part. The second linkage part is a circular structure, and the second toggle part and the locking part are spaced apart and arranged on the circumferential side of the second linkage part.

[0016] As a preferred solution of the present invention, the locking paddle includes an unlocking part, which has a circular structure and cooperates with the first linkage part and the second linkage part. An unlocking hole that cooperates with the lock core is provided in the unlocking part, and a driving arm that cooperates with the locking slider is provided on the unlocking part. The first linkage part and the driving arm are arranged at intervals on the peripheral side of the unlocking part.

[0017] As a preferred solution of the present invention, the locking slider is arranged on the right side of the locking peach, the locking slider is provided with a shift groove that cooperates with the locking peach, the stop portion is provided at the top of the locking slider, and the bottom end of the locking slider is provided with a positioning portion that cooperates with the flexible positioning component, the second linkage is provided on the positioning portion, and the rotation of the locking peach can drive the locking slider to move upward or downward.

[0018] Compared with the prior art, the present invention has the following positive effects:

[0019] 1. The convenient magnetic lock provided by the present invention comprises a lock housing, a lock tongue assembly and a locking slider arranged in the lock housing, wherein the lock tongue assembly is connected to the lock housing through the positioning member so that it can be retracted into the lock housing; the locking slider cooperates with the lock tongue assembly so that when the lock tongue assembly is retracted into the lock housing, the lock tongue assembly is limited by the locking slider in the locked state and cannot be extended out of the lock housing, or the locking slider is limited by the lock tongue assembly and cannot be locked. When the magnetic lock of the present invention is in the open state, the lock tongue assembly slides to the right side of the lock housing so that the lock tongue assembly is retracted into the lock housing. If the locking slider is in the locked state, the locking slider limits the lock tongue assembly so that the lock tongue assembly cannot move to the left and extend out of the lock housing, thereby making the door lock unable to be closed after being locked in the open state; or when the magnetic lock is in the open state, the lock tongue assembly is adsorbed in the lock housing, and the lock tongue assembly limits the locking slider in the unlocked state so that the locking slider cannot reach the locked position, thereby making the door lock unable to be locked. The two cooperation modes of the above-mentioned lock tongue assembly and the locking slider can both prevent the magnetic lock from being accidentally locked when the door is open and the lock tongue from being sucked out when the door is closed, thereby preventing the magnetic lock from being locked when the door is closed and the door cannot be opened because no one inside the door unlocks it and the person outside the door does not have the key.

Those skilled in the art will understand the specific meanings of the above terms in the present invention depending on the specific circumstances.

[0040] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] This embodiment provides a convenient magnetic lock, such as Figures 1-14 As shown, it includes a lock housing 1 and a lock tongue assembly 2 and a locking slide 8 arranged in the lock housing 1.

[0043] A positioning member is connected to the bolt assembly 2. When the door is in the open state, the bolt assembly 2 is connected to the lock housing 1 through the positioning member so that it can be retracted into the lock housing 1. The positioning member can be a magnet or an elastic member such as a tension spring, so that the bolt assembly 2 can be positioned in the lock housing 1.

[0044] Specifically, when the positioning member is a magnet, the magnet is provided on the lock tongue assembly 2. When the lock tongue assembly 2 is retracted into the lock housing, the lock tongue assembly 2 is attracted to the lock housing 1 by the magnet. When the door is opened, the magnetic lock of this embodiment retracts the lock tongue assembly 2 into the lock housing 1 and is attracted to the lock housing 1. When the door is closed, the lock tongue assembly 2 slides out of the lock housing 1 and extends into the lock housing 1 under the attraction of the magnet in the lock tongue plate, thereby closing the door.

[0045] In addition, if the positioning member is an elastic member such as a tension spring, the lock tongue assembly 2 is connected to the inside of the lock housing 1 through the tension spring. When the lock tongue assembly 2 is retracted into the lock housing 1, it remains retracted into the lock housing 1 under the action of the tension spring. After closing the door, a magnet is provided in the buckle plate on the door frame. Under the attraction of the magnet in the buckle plate, the lock tongue assembly 2 slides out of the lock housing 1 and extends into the buckle plate, thereby achieving the purpose of closing the door.

[0046] The locking slider 8 cooperates with the lock tongue assembly 2 so that when the lock tongue assembly 2 is retracted into the lock housing 1, the lock tongue assembly 2 is limited by the locking slider 8 in the locked state and cannot be extended from the lock housing 1, or the locking slider 8 is limited by the lock tongue assembly 2 and cannot be locked. When the magnetic lock of this embodiment is in the open state, the lock tongue assembly 2 slides to the right side of the lock housing 1, causing the lock tongue assembly 2 to retract into the lock housing. If the locking slider 8 is in the locked state, the locking slider 8 limits the lock tongue assembly 2, preventing the lock tongue assembly 2 from moving to the left and extending from the lock housing 1, thereby making it impossible to close the door after the door is locked in the open state; or when the magnetic lock is in the open state, the lock tongue assembly 2 is adsorbed in the lock housing 1, and the lock tongue assembly 2 limits the locking slider 8 in the unlocked state, preventing the locking slider 8 from reaching the locked position, thereby making it impossible to lock the door. The two cooperation modes of the above-mentioned lock tongue assembly 2 and the locking slider 8 can both prevent the magnetic lock from being accidentally locked when the door is open and the lock tongue from being sucked out when the door is closed, thereby preventing the magnetic lock from being locked when the door is closed and the door cannot be opened because no one inside the door unlocks it and the person outside the door does not have the key.

[0047] Preferably, a locking latch 6, a first latch latch 51, and a second latch latch 52 are further provided in the lock housing 1. The first latch latch 51 and the second latch latch 52 are respectively abutted against the inner and outer sides of the locking latch 6 and are rotatably connected relative to each other. The first latch latch 51 and the second latch latch 52 can drive the latch assembly 2 to slide toward the right side of the lock housing 1 when the first latch latch 51 and the second latch latch 52 rotate clockwise. The first latch latch 51 and the second latch latch 52 are respectively connected to the inner door handle and the outer door handle, so that when the door lock is unlocked, the door can be opened by rotating the inner door handle or the outer door handle clockwise.

[0048] The rotation of the first locking bolt nut 51 can drive the locking nut 6 to rotate in the same direction.

[0049] The locking paddle 6 is coupled to the locking slide 8. Counterclockwise rotation of the locking paddle 6 drives the locking slide 8 to slide and restrict the second bolt paddle 52 from rotating clockwise to achieve a locked state. Clockwise rotation of the locking paddle 6 drives the locking slide 8 to release the restriction on the second bolt paddle 52 to achieve an unlocked state. The locked state of the door means that the second bolt paddle 52 cannot drive the bolt assembly 2 to move to the right, so that the rotation of the door handle cannot achieve the door opening operation.

[0050] The locking peach 6 is coupled to the lock cylinder, and a key can be inserted into the lock cylinder from either the inside or outside of the door to rotate the locking peach 6. Locking the door can be achieved by rotating the locking peach 6 counterclockwise using the key. Alternatively, locking can also be achieved by rotating the first bolt peach 51 counterclockwise using the door handle. Similarly, unlocking can be achieved by rotating the first bolt peach 51 clockwise using the door handle, or by rotating the locking peach 6 clockwise using the key.

[0051] When the lock body of the door lock of this embodiment is in use, the door handle can be turned counterclockwise from the inside to lock, and can be turned clockwise to unlock or open the door; the key can be turned counterclockwise from the outside to lock, and can be turned clockwise to unlock, and in the unlocked state, the door can be opened from the outside by the door handle; in addition, when the door is open, the door lock can have two functions: unable to lock, or unable to close after being locked.

[0052] Example 2:

[0053] This embodiment is a specific implementation of embodiment 1. The convenient magnetic lock provided by this embodiment is as follows: Figure 4-Figure 7 As shown, a limit hook 222 is provided at the right end of the lock tongue assembly 2, and a stop portion 85 is provided on the locking slider 8. When the lock tongue assembly 2 is retracted in the lock housing 1 and the locking slider 8 is in a locked state, the stop portion 85 is stuck on the left side of the limit hook 222 to prevent the lock tongue assembly 2 from sliding to the left and extending out of the lock housing 1.

[0054] Specifically, if Figure 4 As shown, when the door is opened and the door lock is unlocked, the locking slider 8 slides downward, as shown in FIG. Figure 6 As shown, when the door is opened and the door lock is in the locked state, the locking slider 8 slides upward and makes the stop portion 85 abut against the limit hook 222. The locked state can be achieved by driving the first lock bolt 51 to rotate counterclockwise by the door handle or by driving the locking bolt 6 to rotate counterclockwise by the key.

[0055] Preferably, a first linkage member 4 is provided on the locking peach 6. The first linkage member 4 protrudes from the inner side of the locking peach 6 and is clamped on the first lock tongue peach 51, so that the rotation of the first lock tongue peach 51 can drive the locking peach 6 to rotate in the same direction. Specifically, a through hole 61 is provided on the locking peach 6, and the first linkage member 4 is inserted into the through hole 61.

[0056] Preferably, a second linkage member 7 is provided on the locking slider 8. The second linkage member 7 protrudes from the outer side of the locking slider 8 and can be clamped on the second lock tongue nut 52 to limit the clockwise rotation of the second lock tongue nut 52. Specifically, a limiting hole 82 is provided on the locking slider 8, and the second linkage member 7 is inserted into the limiting hole 82.

[0057] The first linkage member 4 and the second linkage member 7 may be screws, positioning cards or latches, etc.

[0058] Preferably, the first bolt paddle 51 includes a first linkage portion 514 that cooperates with the interior door handle, a first toggle portion 511 that cooperates with the bolt assembly 2, and an unlocking portion 512 that cooperates with the first linkage member 4. The first linkage portion 514 has a circular structure, with the first toggle portion 511 and the unlocking portion 512 spaced apart and arranged around the circumference of the first linkage portion 514. A locking portion 513 that cooperates with the first linkage member 4 is provided at one end of the first toggle portion 511 near the first linkage portion 514. The locking portion 513 and the unlocking portion 512 are arranged opposite each other, and the first linkage member 4 extends between the locking portion 513 and the unlocking portion 512.

[0059] Specifically, when the first lock bolt shifter 51 is rotated clockwise by the first toggle portion 511, the lock bolt assembly 2 slides to the right. When it is rotated counterclockwise by the locking portion 513, it cooperates with the first linkage member 4 to drive the locking shifter 6 to rotate counterclockwise. When it is rotated clockwise by the unlocking portion 512, it cooperates with the first linkage member 4 to drive the locking shifter 6 to rotate clockwise.

[0060] Preferably, the second lock tongue paddle 52 includes a second linkage part 523 for connecting with the outside door handle, a second toggle part 521 cooperating with the lock tongue assembly 2, and a locking part 522 cooperating with the second linkage part 7. The second linkage part 523 is a circular structure, and the second toggle part 521 and the locking part 522 are arranged at intervals on the circumferential side of the second linkage part 523.

[0061] Specifically, the second bolt puller 52 drives the bolt assembly 2 to slide to the right when it is rotated clockwise by the second toggling portion 521. The locking operation is performed by being stuck in the second linkage member 7 by the locking portion 522.

[0062] In this embodiment, the first lock tongue paddle 51 and the second lock tongue paddle 52 can be configured to include a linkage portion, a toggle portion, an unlocking portion, a locking portion and a locking portion, so that they can be installed without distinguishing between the inside and the outside during use.

[0063] Preferably, the lock tongue assembly 2 is provided with a latching portion 221 that cooperates with the first toggle portion 511 and the second toggle portion 521. The latching portion 221 is provided at one end near the limit hook 222. The latching portion 221 is provided to the right of the first toggle portion 511 and the second toggle portion 521. The lock tongue assembly 2 includes a lock tongue 21 and a push-pull tab 22. The push-pull tab 22 is connected to the lock tongue 21 and can slide along the extension and contraction direction of the lock tongue 21. The push-pull tab 22 extends from the lock tongue 21 to above the first lock tongue peg 51 and the second lock tongue peg 52. The latching portion 221 is provided at the end of the push-pull tab 22 away from the lock tongue 21. A magnet is provided in the lock tongue 21. Clockwise rotation of the first toggle portion 511 and the second toggle portion 521 can push the latching portion 221 to slide to the right.

[0064] Preferably, a flexible positioning component 3 is also provided in the lock housing 1, and the flexible positioning component 3 includes a positioning member and an elastic member. The positioning member is connected to the lock housing 1, and the elastic member is matched with the locking slider 8 or the locking peach 6 to position the locking slider 8 and the locking peach 6 in the locked state or the unlocked state.

[0065] like Figure 5 As described above, the locking slider 8 in the unlocked state is clamped on the flexible positioning component 3, as shown in FIG. Figure 6 As shown, the locking slider 8, in the locked state, is engaged with the flexible positioning assembly 3. The flexible positioning assembly 3 positions the locking slider 8, preventing it from sliding naturally and causing the locked state of the door lock to become unstable. When operating the door lock, the applied rotational force overcomes the elastic force of the flexible positioning assembly 3, changing the locked state of the door lock.

[0066] Preferably, if Figure 2 As shown, the positioning member includes a connecting column 31, a connecting plate 32 and a positioning plate 34. The connecting column 31 and the connecting plate 32 are connected to the lock housing 1. The positioning plate 34 is sleeved on the connecting column 31 and vertically connected to the connecting column 31 and the connecting plate 32. The elastic member is a cylindrical spring 33. The cylindrical spring 33 is sleeved on the positioning plate 34 between the connecting column 31 and the connecting plate 32. A limiting groove 341 that cooperates with the locking slider 8 is provided on the end of the positioning plate 34 away from the connecting plate 32. The cylindrical spring 33 provides a buffering force in the left and right directions for the positioning plate 34, so that the positioning plate 34 plays a positioning role on the locking peach 6 or the locking slider 8. The limiting groove 341 is provided with two adjacent positioning grooves in the upper and lower parts. Specifically, as shown in FIG. Figure 5 and Figure 6As shown, the positioning plate 34 positions the positioning portion 83 of the locking slider 8. When locked, the positioning portion 83 engages the upper side of the limiting groove 341; when unlocked, the positioning portion 83 engages the lower side of the limiting groove 341. The elastic member can be implemented as a spring, a spring, an elastic rubber, or other elastic component. Furthermore, a connecting hole 84 can be provided on the locking slider 8 for connecting to a spring to thereby position the locking slider 8.

[0067] Preferably, the locking paddle 6 includes an unlocking portion 64, which has a circular structure and cooperates with the first linkage portion 514 and the second linkage portion 523. An unlocking hole 641 that cooperates with the lock core is provided in the unlocking portion 64, and a lever arm 63 that cooperates with the locking slider 8 is provided on the unlocking portion 64. The first linkage part 4 and the lever arm 63 are arranged at intervals on the peripheral side of the unlocking portion 64.

[0068] Preferably, the locking slider 8 is disposed on the right side of the locking peach 6. The locking slider 8 is provided with a shifting groove 81 that cooperates with the locking peach 6. A stop portion 85 is provided at the top of the locking slider 8. The bottom of the locking slider 8 is provided with a positioning portion 83 that cooperates with the flexible positioning assembly 3. The second linkage member 7 is provided on the positioning portion 83. The rotation of the locking peach 6 can drive the locking slider 8 to move upward or downward. Specifically, the inner sides of the upper and lower ends of the locking slider 8 are respectively provided with sliding columns. The inner side of the lock housing 1 is provided with a vertically arranged slide groove 11. The locking slider 8 is slidably connected in the slide groove 11 via the sliding column to enable the locking slider 8 to slide up and down in the lock housing 1.

[0069] Specifically, the shifting groove 81 of the locking slide 8 is matched with the shifting arm 63 of the locking peach 6 so that the locking peach 6 rotates counterclockwise to drive the locking slide 8 to slide upward. Figure 11 As shown, the positioning portion 83 moves to the upper side of the flexible positioning component 3 and enters the rotation track of the locking portion 522 of the second lock tongue 52 to achieve locking; Figure 9 As shown, the clockwise rotation of the locking paddle 6 can drive the locking slider 8 to slide downward, and the positioning portion 83 moves to the lower side of the flexible positioning component 3, disengaging from the rotation track of the locking portion 522 of the second lock tongue paddle 52, thereby achieving unlocking.

[0070] When the convenient magnetic lock body of this embodiment is in use, when the door is open, Figure 6 and Figure 7 As shown, the first lock bolt 51 can be driven to rotate counterclockwise by the door handle, or the locking bolt 6 can be driven to rotate counterclockwise by the key, so that the locking slider 8 can slide upward and engage with the limit hook 222, so that the lock bolt 21 cannot extend out of the lock shell 1 and the door closing operation cannot be completed.

[0071] When the door lock is in unlocked state, Figure 8 and Figure 9 As shown, when opening the door indoors or outdoors, the first lock tongue paddle 51 or the second lock tongue paddle 52 is driven to rotate clockwise by the inner door handle or the outer door handle, and the first toggle portion 511 or the second toggle portion 521 pushes the latching portion 221 on the push-pull piece 22, causing the lock tongue assembly 2 to move to the right, and the lock tongue 21 retreats into the lock housing 1, thereby achieving door opening.

[0072] When the door is locked by the inner handle, the first lock bolt 51 is rotated counterclockwise. Figure 10 As shown, the locking part 513 is stuck on the first linkage member 4 to drive the locking peach 6 to rotate counterclockwise, and the arm 63 of the locking peach 6 is stuck in the slot 81 of the locking slider 8, thereby driving the locking slider 8 to slide upward, so that the positioning part 83 is stuck on the upper side of the limiting slot 341 of the positioning plate 34, and the second linkage member 7 slides into the rotation track of the second lock tongue peach 52, so that the second lock tongue peach 52 cannot rotate further clockwise, and the second toggle part 521 cannot touch the locking part 221, so that the door lock is in a locked state. Here, you can also insert a key into the unlocking hole 641 of the locking peach 6 from outside the door, as shown in FIG. Figure 11 As shown, the locking peach 6 is rotated counterclockwise to achieve locking.

[0073] When the door is closed and unlocked by the inside handle, Figure 13 As shown, the first lock bolt paddle 51 rotates clockwise, the unlocking portion 512 is clamped on the first linkage member 4 to drive the locking paddle 6 to rotate clockwise, and the arm 63 of the locking paddle 6 is clamped in the clamping groove 81 of the locking slide 8, thereby driving the locking slide 8 to slide downward, so that the positioning portion 83 is clamped on the lower side of the limiting groove 341 of the positioning plate 34, and the second linkage member 7 exits the rotation track of the second lock bolt paddle 52, so that the door lock is in the unlocked state. Here, unlocking can also be achieved by inserting a key into the unlocking hole 641 of the locking paddle 6 from outside the door and rotating the locking paddle 6 clockwise.

[0074] Example 3

[0075] The convenient magnetic lock in this embodiment is different from that in embodiment 2 in that Figure 14 and Figure 15 As shown, a limiting portion 223 is provided on the lower side of the lock tongue assembly 2, and a stop portion 85 is provided on the locking slider 8. When the lock tongue assembly 2 is retracted in the lock housing 1, the limiting portion 223 is stuck on the upper side of the stop portion 85 to prevent the locking slider 8 from performing a locking movement.

[0076] When the door is in the open state, the lock tongue assembly 2 is retracted in the lock housing 1, and the limiting portion 223 on the lock tongue assembly 2 is stuck on the upper side of the stop portion 85, so that the locking slider 8 in the unlocked state cannot slide upward, and the second linkage member 7 cannot slide to the running track of the locking portion 522, and the locking operation cannot be performed, so that the door cannot be locked in the open state.

[0077] Example 4

[0078] The convenient magnetic lock in this embodiment differs from that in Example 2 in that a rotation stop 225 is provided on the lower side of the bolt assembly 2, and a rotation latch 66 is provided around the locking nut 6. When the bolt assembly 2 is retracted into the lock housing 1, the rotation stop 225 is engaged with the upper side of the rotation latch 66, thereby preventing the locking nut 6 from rotating counterclockwise and simultaneously preventing it from driving the locking slider 8 to lock. The rotation latch 66 is provided around the unlocking portion 64 between the first linkage member 4 and the lever arm 63.

[0079] When the door is in the open state, the lock tongue assembly 2 is retracted in the lock housing 1, and the rotation stop portion 225 is stuck on the upper side of the rotation card 66, so that the locking paddle 6 cannot rotate counterclockwise, and thus cannot drive the locking slider 8 to slide upward, and cannot make the second linkage member 7 slide to the running track of the locking portion 522, and cannot achieve the locking operation, so that the door cannot be locked in the open state.

[0080] In addition, an abutment portion 65 can be provided on the locking nut 6. The abutment portion 65 is provided on the peripheral side of the unlocking portion 64 between the first linkage member 4 and the lever arm 63. The flexible positioning assembly 3 is provided corresponding to the abutment portion 65, so that the flexible positioning assembly 3 positions the abutment portion 65, thereby positioning the locking nut 6 in the unlocked state and the locked state, and simultaneously positioning the locking slider 8. The positioning member on the flexible positioning assembly 3 is a connecting column 35, and the elastic member is a torsion spring 36. One end of the torsion spring 36 is connected to the lock housing 1 through the connecting column 35, and the other end is connected to the abutment portion 65 through the fixing hole 651.

[0081] It should be noted that the clockwise rotation and counterclockwise rotation described in this article are based on the rotation direction observed from the outside of the door in the accompanying drawings, which is only for the convenience of description and does not indicate or imply that the device or element referred to must be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation of the present invention.

[0082] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with this technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
