[0021] In order to facilitate understanding of the present embodiment, the present embodiment will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0022] See also Figure 1 and Figure 2 The lock structure 1 provided by the present invention comprises a housing 10, a fork assembly 20, a transmission assembly 40 and an anti-lock assembly 60. The housing 10 comprises a bottom shell 11 and a mounting plate 13 connected to each other, and the mounting plate 13 is substantially in the shape of a planar plate and extends along a first direction D1.

[0023] The shift fork assembly 20 is rotatably mounted in the bottom shell 11. The transmission assembly 40 is rotatably mounted in the bottom shell 11 and is in transmission cooperation with the shift fork assembly 20. The anti-lock assembly 60 includes a shift sleeve 62 and an anti-lock tongue 64 which are connected to each other. The anti-lock tongue 64 is movably mounted in the bottom shell 11 to extend or retract into the mounting plate 13 along the second direction D2. The second direction D2 is perpendicular to the first direction D1. The shift sleeve 62 is rotatably mounted in the bottom shell 11 and is used to drive the anti-lock tongue 64. When the anti-lock tongue 64 extends out of the mounting plate 13, the shift sleeve 62 abuts against the transmission assembly 40 to form transmission and when the anti-lock tongue 64 retracts into the mounting plate 13, it is separated from the transmission assembly 40.

[0024] Specifically, the bottom shell 11 is a semi-enclosed rectangular frame structure, that is, it is composed of a bottom plate and four side plates perpendicular to the bottom plate, wherein the bottom shell 11 can be used to install structures such as the fork assembly 20, the transmission assembly 40 and the anti-lock assembly 60. In this embodiment, the bottom shell 11 is also provided with a connector limiting groove 111 extending along the second direction D2, wherein the number of the connector limiting groove 111 is at least one and the extension direction is the same, and the connector limiting groove 111 is in the shape of a long strip, specifically a rectangle or a runway. The connector limiting groove 111 can be used to limit the moving direction of the anti-lock tongue 64, so that the anti-lock tongue 64 can move on the surface of the bottom shell 11 in a direction perpendicular to the mounting plate 13.

[0025] See also Figure 2 and Figure 3 The mounting plate 13 is roughly rectangular, extends along the first direction D1 and is connected to the bottom shell 11. The mounting plate 13 can be used to mount the lock body structure 1 on the door panel. The mounting plate 13 includes a plurality of mounting holes 132, which can be used to penetrate screws and other fixings to fix the lock body structure 1. The mounting plate 13 also includes a plurality of avoidance holes 134, the positions of the avoidance holes 134 correspond to the positions of the lock tongues. By providing the avoidance holes 134, the lock tongues of the lock body structure 1 can be extended from the mounting plate 13, thereby cooperating with the door frame to achieve a locking effect.

[0026] Please also read Figure 1 , Figure 2 and Figure 3 The fork assembly 20 is rotatably mounted in the bottom housing 11 . The fork assembly 20 includes a fork body 22 and a protruding portion 24 protruding from the fork body 22 .

[0027] The protruding portion 24 protrudes outward from the fork body 22, wherein the protruding length of the protruding portion 24 is not limited, and it only needs to be able to cooperate with the transmission assembly 40. The width of the protruding portion 24 can be equal to or slightly smaller than the height of the fork body 22, and the thickness of the protruding portion 24 is not limited here, and it needs to have sufficient strength to push the transmission assembly 40.

[0028] The fork body 22 is rotatably disposed on the bottom shell 11 and is located inside the bottom shell 11. The fork body 22 can be vertically mounted on the bottom shell 11. The fork body 22 is provided with a central through hole 221, which penetrates the fork body 22 in a direction perpendicular to the bottom shell 11. In this embodiment, the central through hole 221 is a square hole, that is, the cross section of the central through hole 221 is a square.

[0029] In some other embodiments, the central through hole 221 may also be in a hexagonal shape or a triangular shape, that is, the cross section of the central through hole 221 may be in a hexagonal shape or a triangular shape.

[0030] The central through hole 221 can be used to cooperate with the handle shaft. In order to cooperate with the central through hole 221, the shape of the handle shaft is designed to be a rectangular parallelepiped, a hexagonal prism or a triangular prism. The cooperation between the handle shaft and the central through hole 22 allows the fork body 22 to rotate by turning the handle. It should be noted that the fork body 22 can be rotated by turning the handle indoors or outdoors.

[0031] Please also read Figure 3 , Figure 4 and Figure 5 The transmission assembly 40 is rotatably installed in the bottom shell 11 and cooperates with the fork assembly 20 in transmission. Specifically, the transmission assembly 40 cooperates with the protruding portion 24 to form transmission.

[0032] The transmission assembly 40 includes a first transmission sheet 41, which is generally in the shape of a long strip. In this embodiment, the first transmission sheet 41 includes a connecting end 412, a first hinged end 414, and a first transmission end 416 which are connected in sequence. The first hinged end 414 is hinged to the bottom shell 11. The first transmission end 416 abuts against the anti-lock assembly 60 when the anti-lock tongue 64 extends out of the mounting plate 13. The width of the first transmission end 416 is smaller than that of the first hinged end 414, and is generally in the shape of a hook, so as to achieve no interference with other parts of the lock body structure 1 under the condition of satisfying the transmission connection.

[0033] The first transmission piece 41 further includes a stopper piece 418, which is connected to the connection end 412 and protrudes in a direction away from the bottom shell 11. The stopper piece 418 abuts against the fork assembly 20 to form a transmission, so that when the fork assembly 20 rotates, the first transmission piece 41 can be driven. In this embodiment, the plane where the stopper piece 418 is located can be perpendicular to the plane where the connection end 412 is located. In other embodiments, the stopper piece 418 can also be connected to the connection end 412 at other angles to meet the transmission of the fork assembly 20 to the first transmission piece 41.

[0034] Specifically, the stopper 418 includes a first portion 4182 and a second portion 4184, wherein the first portion 4182 is connected to the second portion 4184 and is bent relative to the second portion 4184, so that the stopper 418 is substantially in an "L" shape. By setting the stopper 418 to be the first portion 4182 and the second portion 4184 connected to each other, the second transmission piece 43 stacked on the first transmission piece 41 can be limited to prevent the second transmission piece 43 from moving too far during the rotation process and interfering with other parts of the lock body structure 1. The second portion 4184 abuts against the fork assembly 20, so that the fork assembly 20 can drive the first transmission piece 41 to rotate. In this embodiment, the plane where the first portion 4182 is located can be perpendicular to the plane where the second portion 4184 is located.

[0035] In this embodiment, the first portion 4182 and the second portion 4184 may be connected at other angles.

[0036] The transmission assembly 40 further includes a second transmission piece 43, which is also roughly in the shape of a long strip. The length of the second transmission piece 43 is less than the length of the first transmission piece 41, and the second transmission piece 43 is superimposed on the first transmission piece 41. The second transmission piece 43 abuts against both the first portion 4182 and the second portion 4184, and when the second transmission piece 43 rotates alone, it is separated from the stop piece 418. In this embodiment, in the embodiment shown in FIG. Figure 3 In the perspective shown, the second transmission piece 43 can be disengaged from the stop piece 418 when rotating counterclockwise. When rotating clockwise, it will drive the stop piece 418 to rotate. On the contrary, when the first transmission piece 41 rotates counterclockwise, it will drive the second transmission piece 43 to rotate, and when rotating clockwise, it will be disengaged from the second transmission piece 43. In other embodiments, the second transmission piece 43 may also be disengaged from the stop piece 418 when rotating clockwise.

[0037] In this embodiment, the second transmission sheet 43 includes an abutting end 431, a second hinged end 433 and a second transmission end 435 which are connected in sequence, wherein the abutting end 431 substantially coincides with the connecting end 412, the abutting end 431 abuts against the stopper sheet 418 and is respectively located on both sides of the stopper sheet 418 with the fork assembly 20, specifically, the abutting end 431 and the protruding portion 24 of the fork assembly 20 are respectively located on both sides of the second portion 4184 of the stopper sheet 418. The second hinged end 433 substantially coincides with the first hinged end 414, and the second hinged end 433 is hinged to the first hinged end 414. The second transmission end 435 is also substantially hook-shaped, and its length is less than that of the first transmission end 416. The second transmission end 435 is connected to the second hinged end 433 and is used to drive the main bolt assembly 50. In order to avoid interference with other parts, the width of the second transmission end 435 is less than that of the second hinged end 433.

[0038] See also Figure 2 and Figure 5The lock body structure 1 further includes a main bolt assembly 50, which is disposed in the bottom shell 11 and can extend or retract into the mounting plate 13 along the second direction D2. When the main bolt assembly 50 extends out of the mounting plate 13, it abuts against the second transmission end 435 of the second transmission plate 43, and can be driven by the second transmission end 435 to retract into the mounting plate 13, thereby realizing the unlocking of the main bolt assembly 50, that is, the unlocking of the main bolt assembly 50 can be realized by rotating the fork assembly 20. When the main bolt assembly 50 is retracted into the mounting plate 13, it is separated from the second transmission end 435, that is, the second transmission plate 43 will not affect the retraction of the main bolt assembly 50. In this embodiment, the main bolt assembly 50 is, for example, an inclined bolt structure, that is, when locking, the inclined bolt structure is in inclined contact with the door frame, therefore, the retraction of the main bolt assembly 50 can be realized only by the door frame squeezing the main bolt assembly 50, and there is no need to act on the main bolt assembly 50 alone.

[0039] In some other embodiments, the main lock tongue assembly 50 may also be a square tongue structure or a round tongue structure, or other structures.

[0040] The main lock tongue assembly 50 includes a main lock tongue 51 and a main connecting member 53 that are directly connected. The main lock tongue 51 is exposed from the mounting plate 13. The main connecting member 53 is installed in the bottom shell 11 and can move along the second direction D2. Specifically, a guide structure can be provided on the bottom shell 11 to enable the main connecting member 53 to move along the second direction D2, thereby driving the main lock tongue 51 to extend or retract into the mounting plate 13. The guide structure can be a guide groove provided on the bottom shell 11, or a guide column on the bottom shell 11, or other structures that can realize the function of extending or retracting the main lock tongue 51 into the mounting plate 13.

[0041] Please also read Figure 1 , Figure 3 and Figure 5 The anti-lock assembly 60 is disposed adjacent to the main bolt assembly 50 and is substantially parallel to each other. The anti-lock assembly 60 is away from the fork assembly 20 relative to the main bolt assembly 50. In this embodiment, the anti-lock assembly 60 includes a pull sleeve 62 and an anti-lock tongue 64 that are connected to each other.

[0042] The reverse locking tongue 64 is movably mounted in the bottom shell 11 to extend or retract into the mounting plate 13 along the second direction D2. The reverse locking tongue 64 includes a tongue body 641 and a reverse locking connector 643. The tongue body 641 is substantially in the shape of a rectangular parallelepiped and is exposed from the mounting plate 13. The reverse locking connector 643 is mounted in the bottom shell 11, is substantially in the shape of a rectangular ring, and is mechanically connected to the tongue body 641. The reverse locking connector 643 is provided with a connector limiting column 6431, which protrudes toward the bottom shell 11 and is slidably embedded in the connector limiting groove 111.

[0043] The pull sleeve 62 is surrounded by the anti-lock tongue 64. The pull sleeve 62 is rotatably mounted on the bottom shell 11 and is used to drive the anti-lock tongue 64. Specifically, the pull sleeve 62 is connected to the anti-lock connector 643. When the anti-lock tongue 64 extends out of the mounting plate 13, the pull sleeve 62 abuts against the transmission assembly 40 to form a transmission. Specifically, the pull sleeve 62 abuts against the first transmission end 416 of the transmission assembly 40 and can be driven to rotate by the first transmission end 416. In this embodiment, the first transmission end 416 can drive the pull sleeve 62 to rotate clockwise. The clockwise rotation of the pull sleeve 62 will drive the anti-lock tongue 64 to retract into the mounting plate 13, thereby realizing the unlocking of the anti-lock tongue 64. In other words, the unlocking of the anti-lock tongue 64 can also be realized by rotating the shift fork assembly 20. The pull sleeve 62 is also separated from the transmission assembly 40 when the anti-lock tongue 64 retracts into the mounting plate 13. In other words, the locking of the anti-lock tongue 64 will not be affected by the transmission assembly 40.

[0044] In this embodiment, the dial sleeve 62 can be turned clockwise to unlock, and turned counterclockwise to lock. Since the dialing structure for controlling the dial sleeve 62 is usually installed indoors, locking and unlocking can be achieved indoors. The anti-lock tongue 64 can be unlocked by turning the handle outdoors. Therefore, the lock body structure 1 of the present invention can prevent young children from locking themselves in the house, or the elderly from locking themselves in and being unable to unlock due to illness or other factors.

[0045] In some embodiments, the lock body structure 1 may further include a limiting piece 70 mounted on the bottom shell 11, the limiting piece 70 is provided with a notch 71, the notch 71 is provided along the second direction D2, the anti-locking connector 643 is at least partially embedded in the notch 71, that is, the width of the notch 71 is greater than the thickness of the anti-locking connector 643, and slides relative to the limiting piece 70 under the drive of the dial sleeve 62. By providing the limiting piece 70, the movement of the anti-locking tongue 64 along the second direction D2 can be made smoother, and the probability of the anti-locking tongue 64 getting stuck during the movement can be reduced.

[0046] In some embodiments, the lock body structure 1 may further include a motor 80 mounted on the bottom shell 11, and the motor 80 is connected to the fork assembly 20 in a transmission manner to drive the fork assembly 20 to rotate. In this embodiment, the transmission form is a gear transmission. In some other embodiments, the transmission form may also be a belt transmission or a chain transmission. By driving the fork assembly 20 by the motor 80, the electric unlocking of the lock body structure 1 can be achieved, making the lock body structure 1 more intelligent and having a wider range of applications.

[0047] In summary, the lock body structure 1 provided by the present invention drives the transmission assembly 40 to rotate through the fork assembly 20, and when the anti-lock tongue 64 extends out of the mounting plate 13, the transmission assembly 40 drives the shift sleeve 62 to rotate, and the shift sleeve 62 then drives the anti-lock tongue 64 to retract, so that the outdoor handle can be unlocked from the back lock, preventing young children from locking themselves in the house.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
