Description

Technical Field

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

[0002] Lock bodies are a common device in everyday life, often used in security doors or safes. They typically consist of a latch bolt assembly and a main bolt. When installed in a security door, a sealing strip is installed within the doorframe to enhance the door's airtightness. However, during daily use, deformation of the door can cause the sealing strip within the doorframe to press against the latch bolt assembly. As the latch bolt assembly retracts, it loses its positioning guide and outputs no position signal. This causes the main bolt to lose alignment with the bolt hole in the doorframe, preventing it from successfully entering the hole. Summary of the Invention

[0003] The embodiments of the present application provide a lock body and a door to solve the above-mentioned technical problems.

[0004] The embodiments of the present application achieve the above-mentioned objectives through the following technical solutions.

The anti-insertion mechanism in the anti-insertion position is located in the telescopic path of the tilted tongue assembly and is used to limit the retraction of the tilted tongue assembly into the shell. The anti-insertion mechanism in the release position is spaced from the tilted tongue assembly. The lock core is arranged on the shell, and the lock core includes a lock core dial button. The lock core dial button is used to abut the anti-insertion mechanism and drive the anti-insertion mechanism to move from the anti-insertion position to the release position.

[0006] In one embodiment, the anti-insertion mechanism includes a stopper and a transmission assembly. The stopper is rotatably disposed on the housing, the transmission assembly is disposed on the housing, the stopper is connected to the transmission assembly, and the transmission assembly is located in the moving path of the lock cylinder dial button. The lock cylinder dial button of the lock cylinder is used to drive the transmission assembly to move so that the stopper moves from the anti-insertion position to the release position.

[0007] In one embodiment, the retaining member includes a first rotating plate, a second rotating plate, a rotating connecting plate and a rotating bearing, the rotating connecting plate is connected between the first rotating plate and the second rotating plate, and the rotating bearing is rotatably connected between the first rotating plate and the second rotating plate.

[0008] In one embodiment, the anti-insertion mechanism further includes a reset member connected between the transmission assembly and the housing, and the reset member is used to drive the blocking member to move, so that the blocking member moves from the release position to the anti-insertion position.

[0009] In one embodiment, the lock body also includes a motor transmission assembly and a drive motor. The motor transmission assembly is arranged in the shell, and the stop member is also connected to the motor transmission assembly. The drive motor is arranged in the shell, and the drive motor is connected to the motor transmission assembly and is used to drive the motor transmission assembly to rotate.

[0010] In one embodiment, the motor transmission assembly further includes a first unlocking member, which is transmission-connected to the drive motor. The first unlocking member includes an unlocking body and an unlocking button, which is connected to the blocking member.

[0011] In one embodiment, the lock body further comprises a main lock tongue assembly, which is telescopically arranged in the housing, and the movement of the transmission assembly is also used to drive the main lock tongue assembly to retract into the housing.

[0012] In one embodiment, the transmission assembly includes a linkage member, a first transmission member and a second transmission member. The linkage member is movably arranged on the shell. Both the first transmission member and the second transmission member are movably arranged on the shell. The first transmission member is located in the moving path of the linkage member. The second transmission member is connected to the stop member. The lock cylinder button is used to drive the linkage member to move. The movement of the linkage member is used to abut the main lock tongue assembly and drive the main lock tongue assembly to retract into the shell, and is used to transmit to the stop member through the first transmission member and the second transmission member.

[0013] In one embodiment, the lock body further includes a tongue transmission member, which is movably arranged on the shell, and the second transmission member is located in the moving path of the tongue transmission member.

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1 , an embodiment of the present application provides a lock body 10 , which can be installed on a door panel 30 .

[0028] See also Figure 2 and Figure 3 The lock body 10 includes a housing 11, a latch bolt assembly 19, an anti-insertion mechanism 21 and a lock core 18. The latch bolt assembly 19 is retractably arranged on the housing 11, and the anti-insertion mechanism 21 is arranged on the housing 11. The anti-insertion mechanism 21 can be selectively located in an anti-insertion position or a release position. The anti-insertion mechanism 21 in the anti-insertion position is located in the telescopic path of the latch bolt assembly 19 and is used to limit the retraction of the latch bolt assembly 19 into the housing 11, so that the latch bolt assembly 19 remains in a state of extending out of the housing 11. When the anti-insertion mechanism 21 is in the release position, it is spaced from the latch bolt assembly 19, and the anti-insertion mechanism 21 does not limit the latch bolt assembly 19, so that the latch bolt assembly 19 can be retracted into the housing 11.

[0029] The housing 11 includes a bottom shell 112 and a lining plate 114, which is connected to one side of the bottom shell 112. The bottom shell 112 can be a generally rectangular plate-shaped structure, and the latch assembly 19, the anti-insertion mechanism 21, and the lock cylinder 18 can be disposed on the bottom shell 112. The bottom shell 112 is provided with a first limiting post 1121, a second limiting post 1122, and a third limiting post 1123. The first limiting post 1121, the second limiting post 1122, and the third limiting post 1123 can be generally cylindrical structures and protrude from the bottom shell 112.

[0030] The lining plate 114 may be rectangular and used to mount the lock body 10 on the door panel 30. The lining plate 114 may be provided with a plurality of mounting holes 1142, which can be screwed into the mounting holes 1142 to secure the lock body 10 to the door panel 30. The lining plate 114 also includes a plurality of lock tongue avoidance holes 1144, through which the lock tongue of the lock body 10 can pass to cooperate with the door frame to achieve locking.

[0031] For the convenience of description, the direction in which the latch bolt assembly 19 extends is defined as the X direction, and the direction perpendicular to the direction in which the latch bolt assembly 19 extends is defined as the Y direction.

[0032] In this embodiment, the latch bolt assembly 19 includes a latch bolt 191, a latch bolt connector 193, and a latch bolt elastic member 195. The latch bolt 191 is connected to the latch bolt connector 193. The latch bolt 191 can extend out of the housing 11 through the lock bolt avoidance hole 1144 or retract from the housing 11. The latch bolt elastic member 195 is disposed around the latch bolt connector 193 to provide a force for extending the latch bolt 191 out of the housing 11. The connection between the latch bolt 191 and the latch bolt connector 193 includes an anti-insertion feature.

[0033] The oblique bolt 191 can be a bidirectional bolt, and the specific structure of the bidirectional bolt can refer to the existing structure. When closing the door, the oblique bolt 191 will be squeezed by the door frame and retracted into the housing 11. After successfully locking, the squeezing force disappears and the oblique bolt 191 extends into the lock bolt hole in the door frame.

[0034] The anti-insertion mechanism 21 includes a stopper 211, a reset member 215, and a transmission assembly 213. The stopper 211 is rotatably mounted on the housing 11 and selectively engages or separates the latch bolt connector 193. The stopper 211 can rotate about a rotation axis 2110 to engage or separate the stopper 211 from the latch bolt connector 193. When the anti-insertion mechanism 21 is in the anti-insertion position, the stopper 211 engages the latch bolt connector 193 to prevent the latch bolt assembly 19 from retracting into the housing 11. When the anti-insertion mechanism 21 is in the released position, the stopper 211 separates the latch bolt connector 193, allowing the latch bolt assembly 19 to retract into the housing 11 under external pressure.

[0035] See also Figure 4 The retaining member 211 includes a first rotating plate 2112, a second rotating plate 2113, and a rotating connecting plate 2114. The first rotating plate 2112 can be a roughly triangular plate structure, and the second rotating plate 2113 can be a roughly rectangular plate structure. The rotating connecting plate 2114 connects the first rotating plate 2112 and the second rotating plate 2113. The first rotating plate 2112 and the second rotating plate 2113 are arranged parallel to each other. The retaining member 211 also includes a rotating bearing 2115, which is rotatably disposed between the first rotating plate 2112 and the second rotating plate 2113. The provision of the rotating bearing 2115 can reduce the damage caused by friction to the oblique tongue connecting member 193 during the process of the retaining member 211 and the oblique tongue connecting member 193 being abutted.

[0036] The reset member 215 is used to drive the stopper 211 to move, so that the stopper 211 moves from the unlocked position to the anti-insertion position, thereby achieving the effect of automatically returning the stopper 211 to the anti-insertion position without the need for manual reset by the user. The reset member 215 can be a reset spring, which can be arranged around the rotating shaft 2110 of the stopper 211. The reset member 215 connects the housing 11 and the stopper 211. The reset member 215 provides a force for the stopper 211 to rotate to abut against the oblique tongue connector 193, so as to reset the stopper 211 to the anti-insertion position. The reset spring includes two ends, one of which abuts the housing 11 and the other abuts the stopper 211. In one embodiment, the reset spring is a compression spring, and the end fixed to the housing 11 provides pressure to restore the stopper 211 to the anti-insertion position, or the reset spring is a tension spring, and the end fixed to the housing 11 provides tension to restore the stopper 211 to the anti-insertion position. Under the action of the reset member 215 , the blocking member 211 can abut against the oblique tongue connector 193 to prevent the oblique tongue connector 193 from moving, thereby preventing the oblique tongue assembly 19 from being inserted.

[0037] See also Figure 5The transmission assembly 213 is movably arranged on the bottom shell 112 and can move along the Y direction or in the direction opposite to the Y direction. The blocking member 211 is arranged on the transmission assembly 213. The transmission assembly 213 includes a linkage member 22, a first transmission member 2132 and a second transmission member 2134. The linkage member 22 can be roughly rectangular. The linkage member 22 is provided with a first limiting hole 2210. The first limiting hole 2210 is adaptively arranged with the first limiting column 1121. The first limiting hole 2210 and the first limiting column 1121 limit the range of movement of the linkage member 22 along the Y direction or opposite to the Y direction. The linkage member 22 includes a linkage block 2212. The linkage block 2212 can protrude from the main body of the linkage member 22. The linkage member 22 also includes a linkage end 2214. The linkage end 2214 is used to link the first transmission member 2132, so that when the linkage member 22 moves along the Y direction, the first transmission member 2132 can move opposite to the Y direction.

[0038] The first transmission member 2132 and the second transmission member 2134 are both movably disposed on the housing 11, with the first transmission member 2132 located in the moving path of the linkage member 22, and the second transmission member 2134 connected to the stop member 211. The first transmission member 2132 may include a first transmission end 2130, which is tilted relative to the linkage member 22. When the linkage member 22 moves along the Y direction, the first transmission end 2130 abuts against the linkage end 2214. The force applied by the linkage end 2214 to the first transmission end 2130 causes the first transmission member 2132 to move opposite to the Y direction. The first transmission member 2132 may also include a second transmission end 2131, which may protrude from the main body of the first transmission member 2132. The second transmission end 2131 is used to press the second transmission member 2134, causing the second transmission member 2134 to move opposite to the Y direction.

[0039] The second transmission member 2134 is connected to the stop member 211. Specifically, the second transmission member 2134 is connected between the second rotating plate 2113 and the rotating bearing 2115. The second transmission member 2134 is provided with a second limiting hole 2211. The second limiting hole 2211 is adapted to mate with the second limiting post 1122 on the bottom housing 112. The second limiting hole 2211 and the second limiting post 1122 limit the range of movement of the second transmission member 2134 in the Y direction or opposite to the Y direction. The second transmission member 2134 may include a third transmission end 2135, and the third transmission end 2135 matches the second transmission end 2131. The second transmission end 2131 presses against the third transmission end 2135, so that the second transmission member 2134 moves opposite to the Y direction. The second transmission member 2134 transmits to the blocking member 211, so that the blocking member 211 rotates around the rotating shaft 2110, so that the blocking member 211 is spaced from the oblique tongue connecting member 193, and the blocking member 211 moves to the release position.

[0040] See also Figure 6 The transmission assembly 213 may further include a first driving member 15 and a third transmission member 2136. The first driving member 15 is connected between the linkage member 22 and the third transmission member 2136. The linkage member 22 and the third transmission member 2136 are spaced apart. The third transmission member 2136 may be provided with a third limiting hole 2137. The third limiting hole 2137 and the third limiting post 1123 limit the range of movement of the third transmission member 2136 along the Y direction or opposite to the Y direction.

[0041] The first driving member 15 includes a driving body 151, a first driving portion 153 and a second driving portion 155. The first driving portion 153 and the second driving portion 155 are respectively connected to the two sides of the driving body 151. Therefore, when the first driving portion 153 is pushed, the rotation direction of the driving body 151 is opposite to the rotation direction of the driving body 151 when the second driving portion 155 is pushed. For example, when the first driving portion 153 is pushed, the driving body 151 rotates in the counterclockwise direction; when the second driving portion 155 is pushed, the driving body 151 rotates in the clockwise direction.

[0042] The linkage member 22 is against the first driving part 153, and the third transmission member 2136 is against the second driving part 155. When the linkage member 22 pushes the first driving part 153 to rotate the driving body 151, the second driving part 155 will also rotate accordingly and drive the third transmission member 2136 to move, wherein the movement directions of the linkage member 22 and the third transmission member 2136 are opposite, and the movement of the linkage member 22 will drive the movement of the third transmission member 2136, thereby realizing the linkage between the two. For example, when the linkage member 22 moves along the Y direction, it will push the linkage member 22 to rotate clockwise, and the second driving part 155 will push the third transmission member 2136 to move in the direction opposite to the Y direction, or when the linkage member 22 moves in the direction opposite to the Y direction, it will push the first driving member 15 to rotate counterclockwise, and the second driving part 155 will push the third transmission member 2136 to move along the Y direction.

[0043] The lock body 10 also includes a lock core 18, which includes a lock core body 182 and a lock core dial 184. The lock core dial 184 is used to abut the anti-insertion mechanism 21 and drive the anti-insertion mechanism 21 to move from the anti-insertion position to the release position. The transmission assembly 213 is located in the movement path of the lock core dial 184. The lock core dial 184 is used to abut the transmission assembly 213 and drive the transmission assembly 213 to move. The transmission assembly 213 drives the stopper 211 to rotate from the anti-insertion position to the release position. The lock core 18 is also provided with a keyhole 186. The keyhole 186 can be provided in the lock core body 182 and the lock core dial 184 and can be used to insert a key. The lock core body 182 can be fixedly provided on the housing 11, and the lock core dial 184 is rotatably provided on the lock core body 182. The lock core dial 184 protrudes from the lock core body 182. The rotation of the key can drive the lock core dial button 184 to rotate relative to the lock core body 182. The lock core dial button 184 can be used to abut the anti-insertion mechanism 21 and drive the anti-insertion mechanism 21 to move from the anti-insertion position to the release position.

[0044] Specifically, rotation of the key can drive the lock cylinder dial 184 to rotate relative to the lock cylinder body 182 and selectively abut against the linkage member 22 or the third transmission member 2136. Specifically, the lock cylinder dial 184 abuts against the linkage block 2212 of the linkage member 22. For example, when the second transmission end 2131 is within the rotation range of the lock cylinder dial 184, the lock cylinder dial 184 rotates in the Y direction, pressing against the linkage block 2212, causing the linkage member 22 to move in the Y direction, pressing against the first transmission member 2132. The first transmission member 2132 then presses against the second transmission member 2134 in the opposite Y direction. The second transmission member 2134 then rotates in conjunction with the stopper 211, causing the stopper 211 to be spaced from the abutting member and the latch connector 193, thereby moving the stopper 211 to the released position. When the lock cylinder dial 184 is no longer abutting against the linkage member 22, the reset member 215 positions the stopper 211 in the anti-insertion position.

[0045] See also Figure 7 In one embodiment, the lock body 10 further includes a main lock tongue assembly 12 , which is telescopically disposed in the housing 11 , and the movement of the transmission assembly 213 is also used to drive the main lock tongue assembly 12 to retract into the housing 11 .

[0046] For example, when the key is rotated to drive the lock cylinder button 184 to abut against the linkage member 22 and push the linkage member 22 to move along the Y direction, it will eventually drive the main lock tongue assembly 12 to retract from the outside of the shell 11, thereby realizing manual unlocking of the lock body 10.

[0047] See also Figure 7The lock body 10 further includes a drive motor 142 and a motor drive assembly 143. The drive motor 142 is connected to the motor drive assembly 143 to drive the motor drive assembly 143 to rotate. The drive motor 142 can be powered by a power supply, wherein the power supply can be a battery, dry cell battery, or external AC power provided inside the housing 11. The motor drive assembly 143 includes a toggle 131 and a motor transmission member 132. The motor transmission member 132 is connected to the toggle 131 and is used to drive the toggle 131 to rotate. The toggle 131 can drive the main lock bolt assembly 12 to move. That is, the main lock bolt assembly 12 can be driven by the motor to retract from the outside of the housing 11 or to extend from the housing 11, thereby achieving electric unlocking or electric locking.

[0048] In this embodiment, the motor transmission member 132 and the toggle member 131 are integrally formed to simplify the production process of the motor transmission member 132 and the toggle member 131. The motor transmission member 132 may be provided with a plurality of gear teeth, which may be disposed on a portion of the outer circumference of the motor transmission member 132. The drive body 151 is used to drive the toggle member 131 to rotate. The drive body 151 drives the motor transmission member 132 to rotate through the rotation of the gears, thereby driving the toggle member 131 to rotate.

[0049] See also Figure 8 The motor drive assembly 143 also includes a first unlocking member 137, which includes an unlocking body 1371 and an unlocking dial button 1373. The unlocking body 1371 is connected between the motor transmission member 132 and the dial member 131, so that the motor transmission member 132 can drive the unlocking body 1371 to rotate, and the unlocking dial button 1373 extends outward from the unlocking body 1371. The unlocking dial button 1373 is roughly hook-shaped, and the unlocking dial button 1373 is connected to the stop member 211, so that the unlocking dial button 1373 can drive the stop member 211 to separate from the oblique tongue connecting member 193. The unlocking dial button 1373 is driven by the driving motor 142, thereby achieving the effect of electrically releasing the anti-insertion function.

[0050] The lock body 1010 also includes a triangular tongue assembly 23, which is retractably mounted within the housing 11. The triangular tongue assembly 23 includes a triangular tongue 231, a triangular tongue connector 233, and a triangular tongue elastic member 235. The triangular tongue 231 is connected to the triangular tongue connector 233, which is movably mounted within the bottom housing 112 to drive the triangular tongue 231 to extend or retract from the housing 11. The triangular tongue elastic member 235 is mounted around the triangular tongue connector 233 to provide the force for the triangular tongue 231 to extend from the housing 11.

[0051] The triangular tongue 231 is a roughly triangular plate-shaped structure. When the triangular tongue 231 is subjected to a compressive force in the opposite direction to the X-direction, such as from the door frame, the triangular tongue 231 retracts from the outside of the housing 1111. When the force ceases, the triangular tongue 231 is extended from the housing 1111 by the force of the triangular tongue elastic member 235. It should be noted that the door frame does not have a corresponding latch hole for the triangular tongue 231. Therefore, when the door is closed, the triangular tongue 231 retracts into the housing 11, driving the triangular tongue connector 233 to move.

[0052] The lock body 10 also includes a tongue transmission member 24, which is rotatably mounted on the bottom housing 112. A second transmission member 2134 is located in the movement path of the tongue transmission member 24. The telescopic movement of the triangular tongue assembly 23 drives the second transmission member 2134 relative to the housing 11 through the tongue transmission member 24, thereby moving the stop member 211 from the anti-insertion position to the release position.

[0053] The tongue-touch transmission member 24 is positioned in the travel path of the triangular tongue connector 233. When the triangular tongue connector 233 extends, it drives the tongue-touch transmission member 24 to rotate clockwise. This rotation drives the second transmission member 2134 to move in the direction opposite to Y, causing the second transmission member 2134 to drive the retaining member 211 to separate from the latch bolt connector 193. This effectively releases the anti-insertion effect of the triangular tongue 231. When the door is opened, the triangular tongue 231 extends, preventing the latch bolt assembly 19 from striking the door frame due to the anti-insertion effect when closing the door. When the triangular tongue connector 233 retracts, the tongue-touch transmission member 24, under the action of the reset member 215, rotates counterclockwise and separates from the second transmission member 2134. The retaining member 211, under the action of the reset member 215, abuts against the latch bolt connector 193, effectively preventing the latch bolt assembly 19 from being inserted into the door.

[0054] The present application also provides a door 1 , comprising a door panel 30 and a lock body 10 according to any one of the above embodiments. The door panel 30 is provided with a mounting groove 32 , and the lock body 10 is disposed in the mounting groove 32 .

[0055] The lock body 10 provided in the present application is mounted on a door panel 30. Since the anti-insertion mechanism 21 in the anti-insertion position is located in the telescopic path of the latch bolt assembly 19 and is used to restrict the latch bolt assembly 19 from retracting into the housing, this prevents the sealing strip in the door frame from pressing against the latch bolt assembly 19 and causing the latch bolt assembly 19 to retract. The latch bolt assembly 19 outputs a position signal, and the main latch bolt assembly 12 is aligned with the latch bolt hole provided in the door frame, which facilitates the main latch bolt assembly 12 to successfully enter the latch bolt hole, thereby improving the security of the lock body 10. Furthermore, since the lock cylinder dial button 184 is used to abut the anti-insertion mechanism 21 and drive the anti-insertion mechanism 21 to move from the anti-insertion position to the release position, and since the anti-insertion mechanism 21 in the release position is spaced apart from the latch bolt assembly 19, the anti-insertion mechanism 21 does not restrict the latch bolt assembly 19, allowing the latch bolt assembly 19 to retract into the housing 11, thereby improving the security of the lock body 10.
