In addition, the traditional indoor door or bathroom door lock body is a double-tongue lock body, and has a locking function in which a key or a knob extends the latch bolt. The double-tongue design requires an extra hole to be opened on the door frame, which makes the lock body structure strength of the traditional double-tongue design average and the service life short. In addition, the lock body structure of the locking door body often makes a "click" noise when locking the door, which needs to be improved. Therefore, we propose a horizontally operated magnetic silent lock body. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all of the embodiments.

[0019] Embodiment 1, as Figure 1-2 As shown, the utility model provides a technical solution: a horizontally operated magnetic silent lock body, comprising a lock shell 2, a bathroom dial wheel 6 and a door hand dial wheel 9 rotatably installed inside the lock shell 2, a door hand dial wheel protrusion 901 is fixedly arranged on the outside of the door hand dial wheel 9, a lock rod 403 is slidably arranged on the inner wall surface of the lock shell 2, a locking block 8 vertically arranged with the lock rod 403 is slidably arranged on the inner wall surface of the lock shell 2, a groove body for realizing the sliding of the locking block 8 is opened on the surface of the lock shell 2 located below the locking block 8, a boss matched with the groove body is arranged on the surface of the locking block 8, a locking groove 402 for engaging with the locking block 8 is opened in the middle of the locking rod 403, a magnetic lock tongue 4 is fixedly arranged on one end of the locking rod 403, a card slot 401 engaged with the door hand dial wheel protrusion 901 is opened on the other end of the locking rod 403, a shell panel 1 is fixedly arranged on one end of the lock shell 2, and a lock tongue slot hole for the magnetic lock tongue 4 to extend is opened on the surface of the shell panel 1;

[0020] A stop column is fixedly arranged inside the lock housing 2, a spring receiving groove is opened on the surface of one side of the lock rod 403 close to the magnetic lock tongue 4, the stop column is embedded in the spring receiving groove, a magnetic tongue reset spring 5 is clamped inside the spring receiving groove, one end of the magnetic tongue reset spring 5 is in contact with the inner wall of the spring receiving groove and is hung with the inner wall of the spring receiving groove, and the other end is in contact with the surface of the stop column and is hung with the stop column;

[0021] A bathroom dial wheel protrusion 601 is fixedly provided on the outside of the bathroom dial wheel 6 for driving the locking block 8 to move up and down.

[0022] In a specific embodiment of the present invention, a door handle is installed on the door hand dial wheel 9, and when the door handle is turned, the door hand dial wheel 9 can be driven to rotate synchronously. A locking knob is installed on the outside of the bathroom dial wheel 6, and rotating the locking knob can synchronously drive the bathroom dial wheel 6 to rotate. When it is necessary to switch from the door opening state to the door closing state, the door hand needs to be turned to make the door hand dial wheel 9 rotate clockwise. At this time, the rebound spring 902 twists and stores energy, and the magnetic tongue reset spring 5 stretches and stores energy. The door hand dial wheel protrusion 901 of the door hand dial wheel 9 cooperates with the card slot 401 to drive the lock rod 403 to move right, so that the magnetic lock tongue 4 is stored in the shell panel 1. Then the door is closed, and the door hand dial wheel 9 is released. The rebound spring 902 rebounds to reset the door hand dial wheel 9, and the magnetic tongue reset spring 5 rebounds to pull the lock rod 403 to move left, so that the magnetic lock tongue 4 is stuck in the door frame. The lock hole of the door frame is opened to complete the door closing action. If the magnetic lock tongue 4 needs to be locked, the bathroom dial wheel 6 needs to be driven to rotate counterclockwise by rotating the locking knob. During the process, the bathroom dial wheel protrusion 601 pushes the upper stopper 802 to move upward, so that the locking block 8 is stuck in the locking groove 402, thereby limiting the lateral movement of the lock rod 403, so that the magnetic lock tongue 4 is firmly stuck in the lock hole of the door frame to complete the door locking action. If the door needs to be unlocked, it is only necessary to drive the bathroom dial wheel 6 to rotate clockwise by rotating the locking knob. During the process, the bathroom dial wheel protrusion 601 pushes the lower stopper 801 to move downward, so that the locking block end 803 of the locking block 8 is separated from the locking groove 402. At this time, rotating the door hand dial wheel 9 clockwise can drive the locking rod 403 to move right as a whole, completing the action of unlocking and opening the door.

[0023] In the preferred technical solution, a lower stopper 801 and an upper stopper 802 are fixedly provided on the surface of the locking block 8 facing the bathroom dial wheel 6, and the bathroom dial wheel protrusion 601 is engaged between the lower stopper 801 and the upper stopper 802. When the bathroom dial wheel 6 is rotated, the bathroom dial wheel protrusion 601 pushes the upper stopper 802 to move upward so that the locking block 8 is engaged in the locking groove 402, that is, the door body is locked; the bathroom dial wheel protrusion 601 pushes the lower stopper 801 to move downward so that the locking block 8 is separated from the locking groove 402, that is, the door body is unlocked.

[0024] In the preferred technical solution, a bathroom dial spring 7 is arranged on the outside of the bathroom dial 6. One end of the bathroom dial spring 7 is clamped on the surface of the convex column arranged inside the lock shell 2, and the other end is clamped on the convex rod arranged on the surface of the bathroom dial 6. The bathroom dial spring 7 stores energy when the bathroom dial 6 rotates counterclockwise. When the bathroom dial 6 is rotated clockwise again to unlock, the bathroom dial spring 7 can assist the bathroom dial 6 to rotate clockwise and reset.

[0025] In the preferred technical solution, a return spring 902 for resetting the door handle dial 9 is provided on the surface of the door handle dial 9. The return spring 902 is embedded on the surface of the door handle dial 9. One end of the return spring 902 is clamped with a boss provided on the surface of the door handle dial 9, and the other end of the return spring 902 is hooked with a hollow column provided inside the lock case 2. When the door handle dial 9 rotates clockwise, the return spring 902 stores energy. When the door handle outside the door handle dial 9 is released, the return spring 90 rebounds to drive the door handle dial 9 and the door handle back to the original position.

[0026] In the preferred technical solution, a chute A is opened on the inner wall surface of the lock case 2 and near the tail end of the lock rod 403, and a chute B is opened on the inner wall surface of the lock case 2 and near the magnetic lock tongue 4. A slider A is integrally formed at the tail end of the lock rod 403, and the slider A is embedded in the chute A. A slider B is integrally formed on the surface of the lock rod 403 near the magnetic lock tongue 4, and the slider B is embedded in the chute B. The sliders are slidably and cooperatively installed in the chutes, which can improve the stability of the lock rod 403 when sliding.

[0027] In the preferred technical solution, the locking groove 402 is vertically aligned with the locking block 8, and the width of the locking groove 402 is 2 mm larger than the width of the locking block end 803 of the locking block 8, which facilitates the smooth insertion of the locking block end 803 into the inside of the locking groove 402.

[0028] In summary, this embodiment provides a lock body structure for horizontal operation. The installation method and the door opening and closing method are both consistent with those of traditional door locks, and are relatively easy to operate. The opening and closing of the door body are realized by controlling the telescopic movement of the magnetic lock tongue through the door handle dial, and the locking and unlocking of the magnetic lock tongue are realized by controlling the vertical movement of the locking block through the bathroom dial. Therefore, there is no need to additionally increase the lock tongue opening and closing structure for locking the door, reducing one of the lock tongue opening and closing structures and still having the function of locking the door of the room. This not only can reduce the cost of the lock body, but also makes less noise when locking the magnetic lock tongue, achieving the effect of silent operation when closing and locking the door.
