[0032] In view of the problem that the conventional lock tongue in the prior art generates relatively large noise inside the lock body due to friction and collision during operation, the utility model provides a lock tongue with a noise reduction function.
[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0034] In this embodiment, a lock tongue with noise reduction function is disclosed. Figure 1 The partial three-dimensional structure of the lock tongue assembly involved in the lock tongue with noise reduction function installed in the housing is shown. Figure 2 The stereoscopic structure of the lock tongue assembly and the noise reduction assembly involved in the lock tongue with noise reduction function is shown from a first viewing angle. Figure 3 The third embodiment shows the stereoscopic structure of the lock tongue assembly and the noise reduction assembly involved in the lock tongue with noise reduction function from a second viewing angle.
[0035] Please refer to Figures 1 to 3 The lock tongue with noise reduction function in the utility model comprises: a shell 1, a lock tongue hole arranged on one side of the shell 1, a lock tongue assembly 2 inserted in the lock tongue hole, and a noise reduction assembly 3 arranged on one side of the lock tongue assembly 2; wherein the lock tongue assembly 2 is arranged inside the shell 1, and one end thereof is inserted in the lock tongue hole; the shell 1 is used to fix the lock tongue assembly 2; and the noise reduction assembly 3 is used to reduce the noise generated by the lock tongue assembly 2 during operation. Figure 1 The figure shows a structure of a half shell of the shell 1, wherein the shell 1 can be formed by buckling two half shells, or by combining a half shell and a cover plate, and a cavity can be formed in the middle of the shell 1, in which a lock tongue assembly 2 and many other structures can be arranged, and the lock tongue assembly 2 is arranged at a position close to the lock tongue hole in the shell 1. When in use, the lock tongue assembly 2 can be extended and retracted along the lock tongue hole to realize the function of opening and closing the lock, and a noise reduction assembly 3 is arranged at one end of the lock tongue assembly 2. The noise reduction assembly 3 is arranged inside the shell 1, which can effectively reduce the noise generated by the lock tongue assembly 2 during the extension and retraction process.
[0036] Secondly, the bolt assembly 2 includes: a pull rod 22, a slanted bolt 21 arranged at one end of the pull rod 22, a guide piece 25 arranged at the other end of the pull rod 22, and a reset spring 23 arranged on the pull rod 22, wherein the pull rod 22 and the guide piece 25 are arranged in the housing 1; the slanted bolt 21 is inserted into the bolt hole and moves under the drive of the pull rod 22; the reset spring 23 is used to reset the slanted bolt 21, the pull rod 22 and the guide piece 25. Figure 2 As shown, one end of the pull rod 22 is fixed with the inclined tongue 21, and the other end is fixed with a guide piece 25. When the guide piece 25 is moved, the guide piece 25 drives the pull rod 22 to move, and then the movement of the pull rod 22 can drive the inclined tongue 21 to retract and expand in the lock tongue hole to complete the function of opening and closing the lock. The reset spring 23 can reset the moved guide piece 25, which is conducive to the inclined tongue 21 to better retract and expand along the lock tongue hole to complete the function of opening and closing the door.
[0037] Secondly, a guide groove 24 is provided on the housing 1, and guide blocks 26 are provided on both sides of the guide sheet 25, wherein the guide blocks 26 are slidably arranged in the guide groove 24. The movement of the guide blocks 26 along the guide groove 24 can limit the movement of the guide sheet 25, so that the bolt assembly 2 can move regularly, ensuring the normal use of the door lock.
[0038] Secondly, a guide seat 27 is provided on the housing 1, and the pull rod 22 is passed through the guide seat 27. The guide seat 27 is used to position the pull rod 22, and the guide seat 27 is used to further ensure the normal operation of the lock tongue assembly 2. A fixing ring 28 is provided at one end of the reset spring 23, and the fixing ring 28 is sleeved on the pull rod 22. One end of the reset spring 23 is fixed to the oblique tongue 21, and the other end is fixed to the fixing ring 28. The fixing ring 28 can prevent the reset spring 23 from passing through the guide seat 27 when the lock tongue assembly 2 is working. The fixing ring 28 abuts against one side of the guide seat 27 to achieve compression of the reset spring 23. The fixing ring 28 is used to fix the reset spring 28 and limit the movement of the reset spring 28.
[0039] Secondly, the guide seat 27 is an L-shaped structure, one side of the guide seat 27 is provided with an opening, the pull rod 22 is inserted into the opening, and the other side of the guide seat 27 is fixed below the guide piece 25. The diameter of the fixing ring 28 is larger than the diameter of the opening, which ensures that the fixing ring 28 will not pass through the guide seat 27, ensuring that the return spring 23 can work normally.
[0040] Secondly, the noise reduction component 3 includes: a buffer ring 31 mounted on one side of the pull rod 22, and a noise reduction sleeve 32 mounted on the guide plate 25 and the guide block 26, wherein the buffer ring 31 is used to reduce the sound generated by the collision between the guide plate 25 and the guide seat 27; the noise reduction sleeve 32 is used to reduce the sound generated by the sliding friction of the guide plate 25 on the guide seat 27. The buffer ring 31 is arranged at one end of the pull rod 22 close to the guide piece 25. When the guide piece 25 is moved, the pull rod 22 moves, and the spring abuts against one side of the fixed seat under the action of the fixing ring 28. The reset spring 23 is compressed, and the paddle is released. The guide piece 25 returns to its original position under the action of the reset spring 23, and collides with the guide seat 27 under the action of inertia. The use of the buffer ring 31 can effectively prevent the guide piece 25 from colliding with the guide seat 27, thereby reducing the sound generated by the operation of the lock tongue assembly 2 inside the shell 1. A noise reduction sleeve 32 is arranged around the guide piece 25 and the guide block 26. The noise reduction sleeve 32 can reduce the friction between the guide piece 25 and the guide block 26 and the surrounding structure, and reduce the sound generated by the friction of the lock tongue assembly 2 in the shell 1.
[0041] Secondly, the noise reduction sleeve 32 is a noise reduction soft sleeve, and the buffer ring 31 is a buffer soft ring. The noise reduction sleeve 32 and the buffer ring 31 are both made of noise reduction materials or soft materials. The noise reduction materials or soft materials have the advantages of high softness and good compression deformation, which can help to slow down the sound generated by the collision of the lock tongue assembly 2, and also help to reduce the sound generated by the friction between the guide plate 25 and the guide seat 27, thereby further reducing the noise of the lock tongue assembly 2.
[0042] Secondly, there are at least two buffer rings 31. The buffer rings 31 are used to reduce the noise generated by the collision of the lock tongue assembly 2. The two buffer rings 31 are used for better buffering, which further increases the buffering stroke of the lock tongue assembly 2, ensures the buffering effect, and can further reduce the noise generated by the contact between the lock tongue assembly 2 and the buffer rings 31.
[0043] In summary, the utility model adds a noise reduction sleeve 32 and a buffer ring 31 to the structure of the existing lock tongue assembly 2, so as to reduce the noise generated by friction and collision of the lock tongue assembly 2 during operation and improve the user experience of the lock.
[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
