The lock body is the main part of the door lock, usually installed on the door frame; the latch is the part of the lock body used to fix the door, which can be movable or fixed; the deadbolt is an extension of the latch, which can cooperate with the door frame or lock slot to lock or open the door; the key is a tool for opening the lock cylinder, and the lock cylinder is the core component of the door lock. Different technologies and structures can be used to open and close the lock according to the type and level of the lock. The door lock can effectively protect the safety of the house and property through the cooperation of the latch and the deadbolt, and the design of the key and the lock cylinder. It is an indispensable and important device in home and commercial buildings.

[0003] However, existing door locks lack sound insulation, and external noise can be transmitted into the room through the gaps or gaps around the door locks, such as noise from corridors, neighboring rooms or the outside environment, which will disturb the quiet and comfortable environment indoors. Secondly, the lack of sound insulation may lead to the leakage of privacy. For example, when such door locks are used in private spaces such as bedrooms or bathrooms, outsiders may hear private conversations or activities in the room, affecting personal privacy and comfort. In addition, for places that require concentration and a quiet environment, such as offices or study areas, the interference of external noise may affect work efficiency and learning effects, causing unnecessary troubles and stress. Therefore, the lack of sound insulation in door locks may affect the quality and comfort of the living and working environment, and further improvements are needed to provide better sound insulation.

[0004] For this reason, we propose an improved soundproof door lock. Utility Model Content

[0023] Example:

[0024] Reference Figures 1 to 4 The utility model embodiment is an improved soundproof door lock, which includes a shell 1, a cover plate 2 is provided on the upper surface of the shell 1, a soundproof foam 3 is provided on the side of the cover plate 2 close to the shell 1, a lock hole 16 is opened on the cover plate 2 and the soundproof foam 3, a plurality of rubber pads 4 are provided on the inner wall of the shell 1, a support column 11 is fixedly connected to the inner wall of the shell 1 away from the cover plate 2, a bottom plate 6 is movably connected to the outer surface of the support column 11, a first fixing member 8 is movably connected to the upper side of the bottom plate 6, the first fixing member 8 is fixedly connected to the inner wall of the shell 1, and the outer side of the bottom plate 6 close to the cover plate 2 is provided with a lock hole 16, and a plurality of rubber pads 4 are provided on the inner wall of the shell 1. A tenon 14 is fixedly connected to the surface, a first notch 13 is provided on the bottom plate 6, a spring 9 is provided between the first fixing piece 8 and the cover plate 2, a top plate 7 is provided on the side of the bottom plate 6 close to the cover plate 2, a plurality of serrations are provided above and below the top plate 7, a second notch 15 is provided on the top plate 7, a lock bolt 10 is fixedly connected to one end of the top plate 7, a second fixing piece 12 is fixedly connected to the outer surface of the support column 11, a lock core 5 is provided on the inner wall of the side of the shell 1 away from the cover plate 2, and the shell 1 is made of high-strength metal materials, such as aluminum alloy or stainless steel, to ensure the firmness and durability of the structure.

[0025] The lock hole 16 has a shape and size that matches the lock core 5. The lock hole 16 matches the lock core 5. The shape and size of the lock hole 16 should completely match the lock core 5 to ensure that the lock core 5 can be smoothly inserted and rotated to achieve the function of opening and closing the door lock.

[0026] The rubber pads 4 are evenly distributed on the inner wall of the outer shell 1. The rubber pads 4 are fixedly connected to the inner wall of the outer shell 1 using an adhesive. The rubber pads 4 are made of a rubber material with good sound insulation performance and durability. The adhesive is selected to have good bonding strength and durability to ensure that the rubber pads 4 are firmly fixed and not easy to fall off or deform.

[0027] The first slot 13 extends along the width direction of the bottom plate 6 , and the first slot 13 allows the bottom plate 6 to move up and down in the vertical direction.

[0028] The second slot 15 extends along the length direction of the top plate 7 , and the second slot 15 allows the top plate 7 to move left and right in the horizontal direction.

[0029] The support column 11 passes through the bottom plate 6 and the top plate 7 through the first notch 13 and the second notch 15 , and the serrations are evenly distributed above and below the top plate 7 .

[0030] An opening is formed on one side of the housing 1 and the rubber pad 4 close to the lock bolt 10 , and the position and size of the opening match the lock bolt 10 .

[0031] Working principle: When the user needs to open the door, first insert the key and rotate the lock cylinder 5, which will cause the iron block on the lock cylinder 5 to rotate and push the bottom plate 6 to move upward. The first notch 13 on the bottom plate 6 allows the bottom plate 6 to move up and down in the vertical direction, so the rise of the bottom plate 6 is not hindered. As the bottom plate 6 rises, the fixation with the top plate 7 is released, and the serrations at the bottom of the top plate 7 engage with the rotating iron block, so that the top plate 7 can move left and right accordingly. This movement process also drives the lock bolt 10 to move horizontally. When the top plate 7 moves to the desired position, the tenon 14 will re-grip the top plate 7 and fix it on the bottom plate 6, completing the re-locking process. The fixation of the tenon 14 ensures the safety of the door in the closed state. During the whole process, the rubber pads 4 are evenly distributed on the inner wall of the shell 1 and are fixedly connected by an adhesive. The function of the rubber pads 4 is to reduce vibration and sound transmission, improve the sound insulation effect, and enable the door to provide better sound insulation performance when closed. When the door is closed, the sound insulation foam 3 is located between the outside and the room, which can absorb and reduce the propagation of sound waves, further improving the sound insulation performance of the door.

[0032] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
