Description
Technical Field
[0001] This utility model relates to the field of door lock technology, and in particular to a lock body structure that extends the life of a door lock. Background Technology
[0002] A door lock, as the name suggests, is a device used to lock a door to prevent others from opening it. It is a very common device used to open and close doors.
[0003] Common door locks typically include a bolt and a handle structure for rotating the bolt. To improve the stability of the lock, a torsion spring is often installed inside the lock body to reset the bolt.
[0004] However, in actual use, some doors have a large flow of people and are opened and closed too many times. Each time they are opened and closed, they need to be locked and unlocked. Over a long period of use, the door lock is opened and closed a lot. As a result, the various parts of the door lock are prone to damage during the high-frequency locking and unlocking process, which leads to poor overall durability and short life of the door lock. Utility Model Content
[0005] To improve durability and extend the lifespan of door locks, this application provides a lock body structure that extends the lifespan of door locks.
[0006] The lock body structure for extending the life of a door lock provided in this application adopts the following technical solution:
[0007] A lock body structure for extending the life of a door lock includes a lock body and a main bolt. The lock body is provided with an assembly groove, and the main bolt is rotatably disposed in and can extend out of the assembly groove. The main bolt is provided with a reset member, which is used to drive the main bolt to reset and rotate. The lock body is rotatably provided with an assembly plate, which can be inserted into the assembly groove. A rotating block is rotatably disposed in the assembly groove. The rotating block is provided with a first abutting block, and the assembly plate is provided with a second abutting block, which can abut against the first abutting block. The lock body is provided with a connecting component, which is used to connect the assembly plate and the main bolt.
[0008] By adopting the above technical solution, the assembly plate is pushed into the assembly slot. During this process, the assembly plate drives the main bolt to rotate and retract into the assembly slot through the connecting component, thereby completing the unlocking. After the assembly plate is released by the reset component, the main bolt can be automatically reset, allowing the main bolt to rotate and extend out of the assembly plate to insert into the corresponding lock slot for locking. At the same time, when the door needs to be opened frequently, the rotating block is pushed to rotate. During the rotation of the rotating block, the first abutting block pushes the second abutting block to rotate, thereby pushing the assembly plate to move and retract into the assembly slot. Through the connecting component, the main bolt rotates, and the rotating block remains in this state. The assembly plate is retracted into the assembly slot, keeping the main bolt in the retracted unlocked state. This keeps the door in a normally open state, eliminating the need for high-frequency locking and unlocking, reducing the door lock opening and closing frequency, reducing the possibility of damage to various door lock components after high-frequency and repeated use, improving durability and thus extending the door lock's lifespan.
[0009] Preferably, the first abutting block is provided with a first limiting groove and a second limiting groove, and the second abutting block can be inserted into the first limiting groove and the second abutting block can be inserted into the second limiting groove.
[0010] By adopting the above technical solution, the second abutment block is inserted into the first or second limiting groove, which improves the stability of the abutment between the second abutment block and the first abutment block in the normal door lock state or the door lock normally open state.
[0011] Preferably, the inner wall of the assembly slot is provided with a first locking block, and the rotating block is provided with a second locking block, the second locking block being able to abut against the first locking block.
[0012] By adopting the above technical solution, the first locking block abutting against the second locking block can improve the stability of the rotating block in the normal door lock state or the door lock always open state, reduce the possibility of the second abutting block and the assembly plate shifting due to accidental rotation of the rotating block, and maintain the stability of the door lock in use.
[0013] Preferably, a rotating plate is rotatably disposed inside the assembly slot, and the rotating plate is rotatably connected to the assembly plate.
[0014] By adopting the above technical solution, the rotating plate is rotatably connected to the inner wall of the assembly slot and the assembly plate. Setting up the rotating plate can improve the stability of the assembly plate moving in the assembly slot, reduce the possibility of shaking or misalignment during the movement of the assembly plate, and improve the convenience of use.
[0015] Preferably, the assembly plate is provided with a rotating shaft, the rotating plate is rotatably connected to the rotating shaft, and a rotating torsion spring is provided on the rotating shaft. One end of the rotating torsion spring abuts against the rotating plate, and the other end of the rotating torsion spring abuts against the assembly plate.
[0016] By adopting the above technical solution, when the assembly plate moves in the assembly slot, it drives the rotating plate to rotate around the rotating shaft. At the same time, the rotating plate and the assembly plate compress the rotating torsion spring together. When the assembly plate is released, the rotating torsion spring returns to its original position and pushes the rotating plate and the assembly plate to move and reset. Thus, after unlocking, the assembly plate is automatically reset and automatically locked, improving the convenience of use.
[0017] Preferably, the connecting assembly includes a connecting pry bar and a connecting block. The connecting block is disposed on the main lock tongue, and the connecting pry bar is rotatably disposed in the assembly slot. One end of the connecting pry bar abuts against the assembly plate, and the other end of the connecting pry bar abuts against the connecting block.
[0018] By adopting the above technical solution, when the assembly plate moves and is inserted into the assembly slot, the assembly plate pushes one end of the connecting pry bar, thereby causing the connecting pry bar to rotate, so that the other end of the connecting pry bar pushes the connecting block, thereby causing the main lock tongue to rotate and retract into the assembly slot, thus realizing unlocking. The operation is simple and convenient, and easy to use.
[0019] Preferably, the lock body is rotatably provided with an unlocking block, the unlocking block is provided with an unlocking latch, the connecting pry bar is provided with a pry bar latch, and the unlocking latch can abut against the pry bar latch.
[0020] By adopting the above technical solution, rotating the unlocking block causes the unlocking latch block to rotate, thereby pushing the pry bar latch block, which in turn drives the connecting pry bar to rotate, pushing the connecting block and the main lock tongue to rotate. The main lock tongue then retracts into the assembly slot, thus completing the process. This facilitates unlocking and locking operations from the other side of the door, improving ease of use.
[0021] Preferably, the inner wall of the assembly slot is provided with a reset shaft, the main lock tongue is rotatably mounted on the reset shaft, and a reset torsion spring is provided on the reset shaft. One end of the reset torsion spring abuts against the main lock tongue, and the other end of the reset torsion spring abuts against the lock body.
[0022] By adopting the above technical solution, when the main lock tongue rotates to unlock, the main lock tongue rotates around the reset shaft and compresses the reset torsion spring at the same time. When the assembly plate is released, the reset spring returns to its original state and pushes the main lock tongue to rotate and extend out of the assembly slot, thereby completing the reset locking. The operation is simple and convenient, and easy to use.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By setting up a lock body, main bolt, assembly slot, reset component, assembly plate, rotating block, first abutment block, second abutment block, and connecting component, pushing the assembly plate into the lock body assembly slot can drive the main bolt to rotate and retract into the assembly slot through the connecting component to unlock. The reset component can drive the main bolt to rotate and reset to extend out of the assembly slot to lock. In scenarios where the door needs to be opened frequently, the rotating block can be rotated to push the second abutment block to move, thereby driving the assembly plate back into the assembly slot. The first abutment block abuts against the second abutment block, keeping the assembly plate in the retracted state of the assembly slot. This keeps the door lock in the unlocked state, thereby reducing the frequency of door lock opening and closing, reducing the possibility of damage caused by frequent opening and closing of the door lock's internal structure, improving durability and extending the door lock's lifespan.
[0025] 2. By setting a rotating plate, a rotating shaft, and a rotating torsion spring, when the assembly plate is pushed to move and insert into the assembly slot, the rotating plate rotates relative to the rotating shaft and compresses the rotating torsion spring. When the assembly plate is released, the rotating torsion spring returns to its original position and pushes the assembly plate to rotate relative to the rotating plate, thereby moving the assembly plate away from the assembly slot, thus automatically resetting and locking, improving the convenience of use.
[0026] 3. By setting up a connecting pry bar and a connecting block, when the assembly plate moves, it pushes one end of the connecting pry bar, causing the connecting pry bar to rotate. When the connecting pry bar rotates, the connecting pry bar at the end away from the assembly plate pushes the connecting block to move, thereby driving the main lock tongue connected to the connecting block to rotate. Thus, the main lock tongue is driven to rotate through the assembly plate, completing the transmission connection and improving the convenience of use. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses a lock body structure for extending the lifespan of a door lock. (Refer to...) Figures 1 to 4The lock body includes a lock body 1 and a main bolt 2. The lock body 1 has an assembly groove 11 inside, and a reset shaft 21 is fixedly mounted on the assembly groove 11. The main bolt 2 is rotatably sleeved on the reset shaft 21 and can extend out of the assembly groove 11 to insert into the corresponding lock groove of the door frame for locking. A reset torsion spring 22 is sleeved on the reset shaft 21 as a reset element. One end of the reset torsion spring 22 abuts against the inner wall of the assembly groove 11, and the other end abuts against the main bolt 2. The lock body 1 is provided with an auxiliary mechanism to enhance the locking stability of the main bolt 2. When the main bolt 2 of the auxiliary mechanism is locked, it abuts against the door frame and does not insert into the lock groove. The lock body 1 is rotatably provided with an assembly plate 3 that can be inserted into and move within the assembly groove 11. The lock body 1 is provided with a connecting component 5, which connects the transmission assembly plate 3 and the main bolt 2. The lock body 1 has a rotating hole 12 communicating with the assembly groove 11 on its surface. An mounting plate 13 is fixedly mounted on the inner wall of the assembly groove 11. A rotating block 4 is rotatably mounted on the mounting plate 13. An auxiliary groove 41 is provided on the surface of the rotating block 4. A first annular abutment block 43 is fixedly mounted on the rotating block 4. The bottom wall of the first abutment block 43 is inclined. A second abutment block 34, which abuts against the first abutment block 43, is fixedly mounted on the side wall of the assembly plate 3 near the rotating block 4. A first limiting groove 431 and a second limiting groove 432 are respectively provided on both sides of the first abutment block 43. The second abutment block 34 can be inserted into the first limiting groove 431 and the second limiting groove 432. A first locking block 131 is fixedly mounted on each side of the mounting plate 13. A second locking block 42, which abuts against the first locking block 131, is fixedly mounted on the side wall of the rotating block 4. When the door needs to be opened frequently, a tool can be inserted into the rotating hole 12 and the auxiliary slot 41. Rotating the rotating block 4 causes the first abutting block 43 to push the second abutting block 34 to rotate, which in turn moves the assembly plate 3 to insert it into the assembly slot 11 and maintains this state. During this process, the movement of the assembly plate 3 drives the main bolt 2 to rotate and retract into the assembly slot 11 through the connecting component 5, maintaining the unlocked state. This reduces the need for frequent unlocking, decreases the possibility of damage from high-frequency use of the door lock, and improves durability to extend the life of the door lock.
[0034] To improve ease of use, refer to Figure 2 and Figure 3 A rotating plate 33 is rotatably mounted on the inner wall of the assembly slot 11 via a rotating shaft. A connecting groove 31 is provided on the surface of the assembly plate 3 near the rotating plate 33. A rotating shaft 32 is provided on the inner wall of the connecting groove 31. The rotating plate 33 is rotatably mounted on the rotating shaft 32. A rotating torsion spring 321 is mounted on the rotating shaft 32. One end of the rotating torsion spring 321 abuts against the rotating plate 33, and the other end abuts against the assembly plate 3. When the assembly plate 3 is used to unlock normally, its movement, in conjunction with the rotation of the rotating plate 33, compresses the rotating torsion spring 321. When the assembly plate 3 is released, the rotating torsion spring 321 returns to its original position, pushing the assembly plate 3 away from the lock body 1, thereby causing the main bolt 2 to return to its original position and lock. The operation is simple and convenient.
[0035] To improve ease of use, refer to Figure 3 and Figure 4 The connecting component 5 includes a connecting pry bar 51 and a connecting block 52. The connecting pry bar 51 is rotatably disposed in the assembly groove 11 and is located between the assembly plate 3 and the main lock tongue 2. The connecting block 52 is integrally fixedly disposed on the side wall of the main lock tongue 2 near the connecting pry bar 51. One end of the connecting pry bar 51 abuts against the bottom wall of the assembly plate 3, and the other end of the connecting pry bar 51 abuts against the connecting block 52. A pry bar locking block 511 is integrally disposed on the bottom wall of the connecting pry bar 51 near the connecting block 52. The lock body 1 is rotatably disposed with an unlocking block 14, which is rotatably inserted into the assembly groove 11. The unlocking block 14 is fixedly disposed with an unlocking locking block 141, which is located in the assembly groove 11 and can abut against the pry bar locking block 511. The unlocking block 14 is provided with an unlocking groove 142. As the assembly plate 3 extends into the assembly slot 11, the assembly plate 3 pushes the connecting pry bar 51, causing the other end of the connecting pry bar 51 to push the connecting block 52, thereby driving the main lock tongue 2 to rotate and retract into the assembly slot 11, thus performing the unlocking operation. The operation is simple and convenient, improving the ease of use.
[0036] The implementation principle of a lock body structure for extending the life of a door lock according to an embodiment of this application is as follows: When the door needs to be opened and closed frequently, rotating the rotating block 4 causes the first abutting block 43 to push the second abutting block 34 to move until the second abutting block 34 is inserted into the second limiting groove 432. During this process, the second abutting block 34 drives the assembly plate 3 to move and insert deeply into the assembly groove 11, thereby pushing the connecting pry bar 51 to rotate. The connecting pry bar 51 pushes the main lock tongue 2 to rotate and retract into the assembly groove 11 through the connecting block 52 and remains in this state, so that the door lock is in the start state, thereby reducing the frequency of door lock opening and closing, reducing wear and tear, and improving the durability and life of the door lock.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
