Description

Technical Field

[0001] This invention relates to the technical field of locks, and more specifically to a lock body assembly and a lock. Background Technology

[0002] Current locks typically consist of a front lock body assembly, a locking mechanism, and a rear lock body assembly arranged in sequence. The front and rear lock body assemblies operate independently of each other to open the locking mechanism. Therefore, if a user accidentally moves the locking mechanism away from its set position during lock installation, the rear lock body assembly may be unable to open the locking mechanism, thus affecting the use of the lock. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a lock body assembly that is conducive to improving interlocking.

[0004] This application also provides a lock that includes the lock body assembly to solve the technical problem that the rotary assembly cannot open the door after the door hole is misaligned.

[0021] This application also provides a lock, including a locking assembly, a rotary assembly, a connecting shaft, and the aforementioned lock body assembly. The lock body assembly, the locking assembly, and the rotary assembly are arranged sequentially along the second direction. The rotary assembly includes a second housing and a rotary element, the rotary element passing through the second housing and fixed to the end of the first rotating shaft away from the first gear. The locking assembly includes:

[0022] A connecting seat having a limiting cavity, wherein the connecting shaft is connected to the first housing and the second housing and passes through the connecting seat;

[0023] The second gear is rotatably disposed within the limiting cavity, and the gear assembly passes through the second gear to drive the second gear to rotate around the first rotating shaft;

[0030] A lock cylinder is connected to the end of the second connector away from the first end to form the second end.

[0031] In some possible implementations, the lock cylinder protrudes from the second connector along the second direction, and the connector is recessed at one end relative to the lock cylinder to form a limiting groove. The lock assembly further includes:

[0040] Because the lock body components have high interconnectivity, even if the user accidentally moves the lock components away from the preset position in the second direction during lock installation, the user can still rotate the toggle to drive the lever to rotate, thereby triggering the transmission process of the gear sleeve and gear assembly, which in turn drives the second gear to rotate and push the lock.

[0041] The second end of the lever moves closer to the first rotating shaft, thereby completing the unlocking step. Therefore, the lock provided by this application can solve the technical problem that the rotary assembly cannot be opened after the door hole is misaligned.

[0054] Reference Figures 1-4One embodiment of this application provides a lock body assembly 100, which includes a first housing 10, a gear sleeve 20, and a first reset member 30 (see reference). Figure 3 ), paddle 40, gear assembly 50 (refer to) Figure 4 ), button 60 and first pivot 70. (Refer to reference) Figure 2 The first housing 10 has a receiving cavity 101, in conjunction with reference to... Figure 3 The gear sleeve 20 has a plurality of protrusions 21 arranged at intervals along the first direction X. A first limiting member 22 is abutted on the end face of the gear sleeve 20 closer to the protrusions 21. For example, the first limiting member 22 can be a screw structure. A first reset member 30 abuts against the side wall of the accommodating cavity 101 and one end of the gear sleeve 20 along the first direction X. For example, the first reset member 30 can be a coil spring (such as...). Figure 3 (As shown) or a type of rubber spring. A paddle 40 is disposed on one side of the gear sleeve 20 near the first limiting member 22. The paddle 40 includes a connecting portion 41 and a actuating portion 42 protruding from at least one side of the connecting portion 41 relative to the first limiting member 22. The actuating portion 42 is disposed on one side of the first limiting member 22 away from the first reset member 30. The gear sleeve 20, the paddle 40, and the first reset member 30 are all confined within the receiving cavity 101. (Refer to...) Figures 2-4 The gear assembly 50 extends out of the receiving cavity 101 away from the first limiting member 22. The gear assembly 50 includes a first gear 51, which is meshed and connected to a plurality of protrusions 21. One end of the button 60 extends out of the first housing 10 away from the gear assembly 50, and the other end of the button 60 is located on the side of the gear sleeve 20 away from the first reset member 30. The button 60 is rotatably connected to the first housing 10 to push the gear sleeve 20 to move along the first direction X. The first rotating shaft 70 passes through the connecting part 41 and the gear assembly 50 along a second direction Y perpendicular to the first direction X. The first rotating shaft 70 is in close fit with the connecting part 41, and the first rotating shaft 70 is in clearance fit with the gear assembly 50. Therefore, the first rotating shaft 70 is in clearance fit with the first gear 51.

[0055] The transmission mechanism of the lock body assembly 100 is as follows: When the user presses the end of the button 60 away from the gear assembly 50, the button 60 rotates relative to the first housing 10. At this time, the button 60 pushes the gear sleeve 20 to move in the first direction X, and the first reset member 30 is compressed. The gear assembly 50 rotates clockwise through the meshing of the first gear 51 and the gear sleeve 20. When the user releases the button 60, the first reset member 30 releases the thrust to reset the gear assembly 50 and the gear sleeve 20. When the user rotates the end of the first rotating shaft 70 away from the button 60, the first rotating shaft 70 drives the paddle 40 to rotate synchronously. At this time, the paddle part 42 pushes the first limiting member 22 to make the gear sleeve 20 move in the first direction X, and the gear sleeve 20 repeats the step of driving the gear assembly 50 to rotate. Therefore, the lock body assembly 100 provided in this application can cause the gear assembly 50 to rotate in the same direction from both ends of the first rotating shaft 70, which is beneficial to improving the interconnectivity of the lock body assembly 100.

[0056] In this application, through the coordinated cooperation of the gear sleeve 20, the paddle 40, the gear assembly 50, the button 60 and the first rotating shaft 70, the transmission process of the gear sleeve 20 and the gear assembly 50 can be triggered by rotating the button 60, and the transmission process of the gear sleeve 20 and the gear assembly 50 can also be triggered by rotating the first rotating shaft 70 to drive the paddle 40 to rotate, thereby improving the interconnectivity of the lock body assembly 100.

[0057] In some embodiments, refer to Figure 4 The gear assembly 50 also includes a sleeve 52, which is detachably fitted inside the end of the first gear 51 away from the paddle 40. The sleeve 52 and the first gear 51 are tightly fitted together, so that the first gear 51 can drive the sleeve 52 to rotate. At this time, the first rotating shaft 70 also passes through the sleeve 52 and the two are fitted with a clearance.

[0058] In some embodiments, refer to Figure 2 The first rotating shaft 70 includes a first shaft portion 71 and a second shaft portion 72 coaxially arranged. The diameter of the first shaft portion 71 is smaller than the diameter of the second shaft portion 72. The first shaft portion 71 passes through the connecting portion 41 and the gear assembly 50. The end of the sleeve 52 away from the first gear 51 abuts against the second shaft portion 72. The shape of the first rotating shaft 70 is conducive to improving the connection stability of the sleeve 52.

[0059] In another embodiment, the diameter of the first shaft portion 71 may be greater than or equal to the diameter of the second shaft portion 72.

[0060] In some embodiments, the second shaft portion 72 can be a square shaft, and the sleeve 52 can also be a square tube, that is,

[0061] The radial cross-section can have a square or similar shape. Using a square shaft or square tube improves installation stability.

[0062] In some embodiments, refer to Figure 3 There are two first reset members 30 and two first limiting members 22. The protrusion 21 is located between the two first limiting members 22. The two first reset members 30 are arranged at intervals relative to each other. The actuating part 42 protrudes from each first limiting member 22 on opposite sides of the connecting part 41. The structure of the first reset member 30 and the first limiting member 22 helps to improve reset stability.

[0063] In some embodiments, refer to Figure 2 and Figure 3 Viewed along the second direction Y, the first housing 10 includes a housing body 11, a second rotating shaft 13, and a mounting base 12 arranged sequentially. Both the second rotating shaft 13 and the mounting base 12 are mounted on the housing body 11. For example, a plurality of first fixing seats (not shown) and two second fixing seats (not shown) spaced apart may be provided on one end face of the housing body 11 opposite to the lever 40. For example, the first and second fixing seats may be integrally formed with the housing body. The mounting base 12 can be fixed to the first fixing seat with screws, and the opposite ends of the second rotating shaft 13 can be fixed within the second fixing seat. The second rotating shaft 13 passes through the button 60 along a third direction Z perpendicular to the first direction X and the second direction Y, causing the button 60 to be rotatably connected to the first housing 10. The mounting base 12 has a receiving cavity 101. For example, the mounting base 12 can be fixed by two oppositely arranged seats engaging to form the receiving cavity 101. The lock body assembly 100 also includes a first torsion spring 80. The spring coil of the first torsion spring 80 is located on the periphery of the second rotating shaft 13. One arm of the first torsion spring 80 abuts against the housing body 11, and the other arm of the first torsion spring 80 is connected to the part of the button 60 located on the side of the second rotating shaft 13 opposite to the receiving cavity 101. The first torsion spring 80 helps the button 60 to quickly reset. Specifically, when the button 60 pushes the gear sleeve 20 to move in the first direction X, the distance between the two arms of the first torsion spring 80 decreases. When the user releases the button 60, the button 60 quickly resets under the deformation recovery action of the spring arms. In addition, the structure of the first housing 10 simplifies the structure of the lock body assembly 100.

[0064] In another embodiment, the button 60 and the first housing 10 can be rotatably connected in other ways. For example, the two pairs of sides of the button 60 can be provided with protrusions, and correspondingly, the first housing 10 can be provided with...

[0065] It has a corresponding socket, and the protrusion can be rotatably set in the socket.

[0066] Reference Figure 1 and Figure 2Another embodiment of this application provides a lock 200, including a locking assembly 110, a rotary assembly 120, a connecting shaft 130, and a lock body assembly 100. The lock body assembly 100, locking assembly 110, and rotary assembly 120 are arranged sequentially along a second direction Y. The rotary assembly 120 includes a second housing 1 and a rotary element 2, which passes through the second housing 1 and is fixed to the end of the first rotating shaft 70 away from the first gear 51. (Refer to reference...) Figure 5 The locking assembly 110 includes a connecting seat 3, a second gear 4, a locking element 5, and a second limiting member 6. The connecting seat 3 has a limiting cavity 301. For example, the connecting seat 3 can also form the limiting cavity 301 by two opposing seats engaging. The connecting shaft 130 connects to the first housing 10 and the second housing 1 and passes through the connecting seat 3. The second gear 4 is rotatably disposed in the limiting cavity 301. The gear assembly 50 passes through the second gear 4 to drive the second gear 4 to rotate around the first rotating shaft 70. Along a third direction Z perpendicular to the first direction X and the second direction Y, the locking element 5 has a first end 504 and a second end 505 disposed opposite to each other. The first end 504 abuts between the second gear 4 and the connecting seat 3, and the second end 505 extends out of the limiting cavity 301. The second limiting member 6 protrudes from the first end 504 and is disposed on at least one side of the second gear 4 opposite to the first reset member 30 and / or the button 60. The teeth of the second gear 4 are located on one side of the second limiting member 6 relative to the second end 505. In specific use, the gear assembly 50 drives the second gear 4 to rotate, so that the teeth of the second gear 4 abut against one side of the second limiting member 6, thereby driving the second end 505 of the lock 5 to move closer to the first rotating shaft 70, thereby disengaging the lock 5 from the preset lock hole, thus completing the unlocking step.

[0067] In this application, because the lock body assembly 100 has high interconnectivity, even if the user accidentally moves the locking component 110 away from the preset position along the second direction Y when installing the lock 200, the user can still rotate the toggle 2 to drive the paddle 40 to rotate, thereby triggering the transmission process of the gear sleeve 20 and the gear assembly 50, thereby driving the second gear 4 to rotate and push the second end 505 of the locking 5 to move closer to the first rotating shaft 70, thus completing the unlocking step. Therefore, the lock 200 provided in this application can solve the technical problem that the toggle assembly 120 cannot be opened after the door hole is deviated.

[0068] In some embodiments, refer to Figure 2 and Figure 5The lock 5 includes a first connector 503, a second connector 502, and a lock cylinder 501. The first connector 503 has a first part 5031 and a second part 5032. The first part 5031 has a first end 504, meaning that the first part 5031 abuts against the second gear 4 and the connecting seat 3, and also has a second limiting member 6. The second part 5032 protrudes from the first part 5031 away from the toggle assembly 120 or the first housing 10. For example, the first part 5031 and the second part 5032 can be arranged perpendicularly or integrally formed. The second part 5032 is located away from the first end 504. The second connector 502 has a connecting hole 506. For example, the connecting hole 506 can be a blind hole or a through hole. The second part 5032 abuts against the wall of the connecting hole 506 closest to the second gear 4. The lock cylinder 501 is connected to the end of the second connector 502 away from the first end 504 to form a second end 505. The structure of the Lock 5 makes it easy to disassemble and assemble.

[0069] In some embodiments, refer to Figure 2 and Figure 5 The lock cylinder 501 protrudes from the second connector 502 along the second direction Y, and the connecting seat 3 is recessed at one end relative to the lock cylinder 501 to form a limiting groove 302. The locking assembly 110 also includes a positioning post 7 and a second reset member 8. One end of the second reset member 8 is located on the periphery of the positioning post 7, and the other end of the second reset member 8 abuts against the bottom wall of the limiting groove 302. The second reset member 8 is located on one side of the first part 5031, away from or opposite to the second part 5032. In this embodiment, the second reset member 8 is located on one side of the first part 5031, away from the second part 5032, to reduce the integrated volume of the locking assembly 110. The second reset member 8 helps the lock 5 to quickly reset after unlocking. For example, the second reset member 8 can be a coil spring or a rubber spring.

[0070] In some embodiments, the locking assembly 110 may further include a protective tube 903, which may be disposed around the locking assembly 5.

[0071] In some embodiments, refer to Figure 5 The number of second limiting members 6 is at least two (four second limiting members 6 are shown in the figure), and at least two second limiting members 6 are relative to the first reset member 30 and the button 60 (see reference). Figure 3 () are located on opposite sides of the second gear 4.

[0072] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 The rotary assembly 120 also includes a limiting tube 9 and

[0073] The second torsion spring 90 and the limiting tube 9 include a tube body 91 and two spaced-apart third limiting members 92. The knob 2 and the first rotating shaft 70 both pass through the tube body 91. The knob 2 drives the tube body 91 to rotate around the first rotating shaft 70. The circumferential surface of the tube body 91 is recessed to form a mounting groove 901. The third limiting members 92 cover part of the opening of the mounting groove 901. The spring coil of the second torsion spring 90 surrounds the bottom wall of the mounting groove 901. Each spring arm of the second torsion spring 90 abuts against the end face of one third limiting member 92 relative to the other third limiting member 92. The second torsion spring 90 facilitates the knob 2's return to its original position after being torn and relaxed.
