Technical Field

[0001] This utility model relates to the field of door lock technology, specifically a lock body with a simple structure. Background Technology

[0002] With the continuous development of technology, door locks are becoming increasingly common in daily life. Most existing door locks consist of a lock case and a bolt. The bolt is retractable and extends within the lock case. The bolt can extend through a bolt hole in the lock case into the keyhole in the door frame to lock the door. Door locks generally use a clutch mechanism to drive the bolt, which extends or retracts into the lock case to unlock and lock the door. The existing bolt and clutch mechanisms are relatively complex, making the overall structure of the door lock quite complex. Utility Model Content

The lever arm is rotatably mounted on the guide shaft of the lock housing. The main tongue plate is provided with a first sliding hole and a guide hole. The main tongue plate is mounted on the guide shaft through the first sliding hole. One end of the lever arm extends into the guide hole. The main tongue is located at the end of the main tongue plate and protrudes from the lock housing. The electric clutch mechanism includes a drive component, an actuating component, a limiting block, a rotating shaft, a linkage plate, and a paddle. The actuating component is used to connect to the handle. The linkage plate is tightly fitted onto the actuating component and engages with the paddle arm. One end of the limiting block and one end of the paddle are rotatably sleeved on the rotating shaft and located around the actuating component. The actuating component has a limiting protrusion on its side. The middle part of the paddle is rotatably sleeved on the handle, and the other end abuts against the connecting rod. When the door is opened, the driving component pushes the other end of the limiting block closer to the actuating component, and the handle is rotated to make the limiting protrusion push the limiting block. The limiting block drives the actuating plate to push the connecting rod, causing the tongue to retract into the lock housing. When the handle is rotated, the linkage plate follows the handle and drives the actuating arm to rotate to push the main tongue into the lock housing.

[0005] Furthermore, the oblique tongue mechanism also includes a first spring, which is sleeved on the connecting rod.

[0006] Furthermore, the actuating element includes an upper actuating element and a lower actuating element, and the actuating piece is disposed between the upper actuating element and the lower actuating element.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] See Figures 1-6 A simple lock body includes a lock shell 100 and a bolt mechanism 200, a main bolt mechanism 300 and an electric clutch mechanism 400 disposed within the lock shell 100; The latch mechanism 200 includes a latch 210 and a connecting rod 220. The latch 210 is connected to the end of the connecting rod 220 and protrudes from the lock housing 100. The connecting rod 220 is slidably disposed within the lock housing 100. The main tongue mechanism 300 includes a main tongue 310, a main tongue plate 320, and a lever 330. The lever 330 is rotatably sleeved on the guide shaft of the lock housing 100. The main tongue plate 320 is provided with a first sliding hole 321 and a guide hole 322. The main tongue plate 320 is sleeved on the guide shaft through the first sliding hole 321. One end of the lever 330 extends into the guide hole 322. The main tongue 310 is disposed at the end of the main tongue plate 320 and protrudes from the lock housing 100. The main tongue plate 320 is slidably disposed within the lock housing 100. The electric clutch mechanism 400 includes a drive component 410, an actuating component, a limiting block 440, a rotating shaft 450, a linkage plate 460, and a paddle 470. The actuating component is used to connect to the handle. The linkage plate 460 is tightly fitted onto the actuating component and engages with the paddle arm 330. One end of the limiting block 440 and one end of the paddle 470 are rotatably sleeved on the rotating shaft 450 and located around the actuating component. The actuating component has a limiting protrusion 421 on its side. The middle part of the paddle 470 is rotatably sleeved on the handle, and the other end abuts against the connecting rod 220. When the door is opened, the drive member 410 pushes the other end of the limiting block 440 closer to the actuating member. The state in which the limiting block 440 is close to the actuating member is the unlocked state of the door lock. At this time, turning the handle can cause the limiting protrusion 421 to push the limiting block 440. The limiting block 440 drives the lever 470 to push the connecting rod 220, causing the latch bolt 210 to retract into the lock housing 100. Specifically, the limiting block 440 pushes the lever 470. Since the middle part of the lever 470 is rotatably fitted on the handle, one end of the lever 470 is pushed by the limiting block 440 and rotates around the handle. During the rotation of the lever 470, it pushes the connecting rod 220, thereby causing the connecting rod 220 to slide with the latch bolt 210 to retract the lock. Lock housing 100; When the handle is rotated, since the linkage plate 460 is tightly fitted onto the actuating member, when the handle drives the actuating member to rotate, the linkage plate 460 also rotates, so that the linkage plate 460 engages with the lever arm 330. Therefore, the linkage plate 460 drives the lever arm 330 to rotate, thereby pushing the main tongue 310 into the lock housing 100. Specifically, when the lever arm 330 rotates, since one end of the lever arm 330 extends into the guide hole 322 of the main tongue plate 320, the rotation of the lever arm 330 can push the main tongue plate 320 to move, thereby retracting the main tongue 310 into the lock housing 100. That is, when the electric clutch mechanism 400 is in the unlocked state, rotating the handle can retract the main tongue 310 and the oblique tongue 210 into the lock housing 100 to open the door.

[0024] When locking the door, rotate the handle in the other direction. The linkage plate 460 drives the lever 330 to rotate in the other direction. The lever 330 pushes the main tongue plate 320 to move, causing the main tongue 310 to extend out of the lock case 100, thereby locking the door.

[0025] In this embodiment, the latch mechanism 200 further includes a first spring 230, which is sleeved on the connecting rod 220. The first spring 230 is used to reset the latch 210. Specifically, when the latch 210 retracts into the lock housing 100, the first spring 230 is compressed. When the handle is released, the first spring 230 rebounds to reset the latch 210 so that it extends out of the lock housing 100.

[0026] In this embodiment, the actuating element includes an upper actuating element 420 and a lower actuating element 430, and the paddle 470 is disposed between the upper actuating element 420 and the lower actuating element 430. The use of the upper actuating element 420 and the lower actuating element 430 makes the effect of the handle driving the paddle 470 to rotate more stable.

[0027] In this embodiment, one end of the linkage plate 460 is provided with a rotating hole, and one end of the actuating member is provided with a turntable. The linkage plate 460 is tightly fitted onto the turntable through the rotating hole to realize the connection between the actuating member and the linkage plate 460.

[0028] In this embodiment, the actuating component is provided with a linkage hole 422, which is used to fit onto the handle to connect the handle and the actuating component.

[0029] In this embodiment, the linkage hole 422 is square, which enables the handle to drive the actuating component in a linkage manner without slipping.

[0030] In this embodiment, the drive unit 410 includes a housing 411 and a motor 412, a first gear 413, a lead screw 414, and a push block 415 disposed within the housing 411. The output shaft of the motor 412 is connected to a second gear 416, which meshes with the first gear 413. The diameter of the second gear 416 is smaller than the diameter of the first gear 413. The lead screw 414 is connected to the center of the first gear 413, and the thread 419 on the surface of the lead screw 414 is a half-turn. The push block 415 is connected to the lead screw 414. Specifically, the push block 415 is loosely fitted onto the lead screw 414 through a sleeve portion, and the push block 415 is partially exposed outside the housing 411. The thread 419 of the lead screw 414 is located inside the sleeve portion. The driving component 410 is used to push the limiting block 440 closer to or away from the limiting protrusion 421. Specifically, the motor 412 is started, and the first gear 413 meshes with the second gear 416 to drive the lead screw 414 to rotate. Since the push block 415 is loosely fitted on the lead screw 414, the push block 415 will not rotate with the lead screw 414. The thread 419 on the lead screw 414 will push the push block 415, so the push block 415 approaches and pushes the limiting block 441. 0. When the limit block 440 is close to the actuating member, the limit protrusion 421 can push the limit block 440 when the actuating member rotates, thereby allowing the latch mechanism 200 to retract into the lock housing 100. When the push block 415 moves away from the limit block 440, it will cause the limit block 440 to move away from the actuating member. When the actuating member rotates, the limit protrusion 421 will not contact the limit block 440, that is, the actuating member will rotate freely. At this time, the door lock is in the locked state and the latch mechanism 200 cannot be opened.

[0031] In this embodiment, the driving component 410 further includes a second spring 417, which is sleeved on the lead screw 414. The two ends of the second spring 417 abut against the housing 411 and the thread 419, respectively. When the motor 412 drives the lead screw 414 to rotate via the first gear 413 and the second gear 416, the thread 419 of the lead screw 414 approaches the spring to compress it. If the motor 412 malfunctions and cannot return the lead screw 414 to its original position in time, the spring's rebound force allows the lead screw 414 to return to its original position.

[0032] In this embodiment, the push block 415 is provided with a second sliding hole 418, and the bottom of the limiting block 440 is provided with a protrusion 441, which is located inside the second sliding hole 418. When the push block 415 moves closer to or further away from the actuating member, since the protrusion 441 is located in the second sliding hole 418, the push block 415 drives the limiting block 440 to move closer to or further away from the actuating member; when the actuating member rotates and causes the limiting protrusion 421 to push the limiting block 440, the protrusion 441 of the limiting block 440 slides inside the second sliding hole 418, that is, the push block 415 does not restrict the movement of the limiting block 440.

[0033] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
