DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-5 As shown, this utility model provides a multifunctional safety and soundproof door and window latch device, including a lock housing 1. Second mounting plates 6 are symmetrically fixedly connected to both sides of the lock housing 1. The second mounting plates 6 allow the lock housing 1 to be securely installed in the corresponding position on the door or window. A ventilation component 3 is provided inside the lock housing 1, which improves the functionality of the latch device. A lock seat 4 is provided on one side of the lock housing 1. First mounting plates 5 are symmetrically fixedly connected to both sides of the lock seat 4. The first mounting plates 5 also stabilize the lock seat 4, ensuring it is installed in a suitable position on the door or window. A latch component 2 is provided inside both the lock housing 1 and the lock seat 4, making opening and closing the door or window sufficiently convenient.

[0021] The locking assembly 2 includes symmetrically arranged movable rods 27, which are slidably disposed within the lock housing 1. The inner cavity of the lock housing 1 is symmetrically provided with guide grooves 24 for use with the movable rods 27. The movable rods 27 are slidably connected to the guide grooves 24, which provide precise guidance for the sliding of the movable rods 27, ensuring that the movable rods 27 always maintain linear motion during movement. A limiting frame 26 is fixedly sleeved on the outer surface of the movable rods 27, and one side of the limiting frame 26 is slidably connected to the inner cavity of the lock housing 1. The limiting frame 26 can prevent the movable rods 27 from shifting in the horizontal direction during movement, ensuring the normal use of the locking device.

[0022] A spring 29 is fixedly connected in parallel to one side of the moving rod 27. The spring 29 automatically returns to its original position and assists in locking when the latch device closes the door or window. When the door or window is closed, the elastic potential energy of the spring 29 can push the moving rod 27. A guide rod 25 that works with the spring 29 is fixedly connected in parallel to one side of the moving rod 27. The spring 29 is slidably sleeved on the outer surface of the guide rod 25. The guide rod 25 provides a stable guide for the extension and retraction of the spring 29, ensuring that the spring 29 can extend and retract in the correct direction when subjected to force. One end of the moving rod 27 passes through the lock housing 1 and is fixedly connected to a locking rod 23. The inner cavity of the lock seat 4 has a lock groove 21 that works with the locking rod 23. The locking rod 23 engages with the lock groove 21. The locking rod 23 and the lock groove 21 in the lock seat 4 cooperate with each other to realize the locking function of the door or window.

[0023] The opposite side of the moving rod 27 is symmetrically fixedly connected with a vertical rod 28, and one side of the vertical rod 28 is fixedly connected with a push rod 22, one end of the push rod 22 away from the vertical rod 28 penetrates the lock shell 1, and the push rod 22 is arranged to facilitate the user to operate the lock device, and the moving rod 27 and the connected parts can be driven to move by manually pushing the push rod 22, so that the door and window can be easily opened and closed, and the convenience of using the lock device is improved.

[0024] The ventilation assembly 3 comprises a supporting seat 33 fixedly installed in the lock shell 1, and the upper surface of the supporting seat 33 is fixedly installed with a servo motor 34, and the supporting seat 33 provides a stable installation basis for the servo motor 34, and the output end of the servo motor 34 is fixedly connected with a ventilation plate 32, so that the output end of the servo motor 34 can drive the ventilation plate 32 to rotate.

[0025] The inner wall of the lock shell 1 is provided with a circular groove 31, and the inner wall of the circular groove 31 is provided with ventilation holes 35 in an annular array for cooperating with the ventilation plate 32, the circular groove 31 provides a space for the rotation of the ventilation plate 32, and the annular array distribution of the ventilation holes 35 makes the ventilation more uniform, the ventilation plate 32 is rotatably connected with the circular groove 31, and the side of the ventilation plate 32 is in close contact with the inner wall of one side of the circular groove 31, the hole position on the ventilation plate 32 corresponds to the position of the ventilation holes 35 in the annular array, and in the case of ensuring that the door and window are closed, a good ventilation effect is achieved, and the functionality of the lock device is improved.

[0026] Working principle: first, the lock seat 4 and the lock shell 1 are firmly installed on the corresponding positions of the door and window through the first mounting plate 5 and the second mounting plate 6, so as to ensure the stability of the installation of the entire lock device on the door and window.

[0027] When it is necessary to close the door and window, the lock rod 23 on one side of the lock shell 1 is pushed to approach the lock groove 21 on the lock seat 4 through the lock assembly 2.

[0028] In this process, the moving rod 27 slides along the guide groove 24 in the lock shell 1, and the limiting frame 26 is slidably connected with the inner cavity of the lock shell 1, so as to limit the sliding range of the moving rod 27 and prevent it from coming out, and the guide rod 25 provides stable guidance for the extension and contraction of the spring 29, avoids the twisting and deformation of the spring 29, and ensures that the elastic performance of the spring 29 normally plays a role.

[0029] When the lock rod 23 is completely inserted into the lock groove 21, the elastic potential energy of the spring 29 drives the moving rod 27, so that the lock rod 23 is tightly connected with the lock groove 21, an automatic locking effect is realized, the door and window are firmly closed, and the convenience of using the lock device is improved.

[0030] When the door and window are closed, if ventilation is needed, the ventilation assembly 3 is started, the servo motor 34 is started, the servo motor 34 drives the ventilation plate 32 to rotate in the circular groove 31 on the inner wall of the lock shell 1, with the rotation of the ventilation plate 32, the opening and closing degree of the ventilation hole 35 changes, effective ventilation and air exchange are realized, and the overall safety and sealing performance of the door and window are not affected, and the functionality of the lock device is improved.

[0031] When the door and window is opened, the two lever rods 22 are manually pinched and moved towards the opposite side, the lever rod 22 drives the moving rod 27 to overcome the elastic force of the spring 29 through the vertical rod 28, so that the lock rod 23 is separated from the lock groove 21, and the door and window can be easily opened, and the setting of the lever rod 22 greatly improves the convenience of the operation of the lock device.

[0032] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
