[0031] Unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0032] In this embodiment, a noise reduction lock is disclosed. Please refer to Figures 1 to 6 The noise reduction lock in this embodiment mainly includes a housing 11, a first locking tongue 21, a paddle 12 and a first buffer 31. The housing 11 is formed by buckling two half shells, and is used to accommodate the locking tongue, the paddle, the buffer and other structures. A locking tongue hole is provided on one side of the housing 11 for the locking tongue to pass through. The first locking tongue 21 is slidably arranged in the housing 11, and its left end can extend out of the housing or retract into the housing through the locking tongue hole to achieve locking and unlocking.
[0033] A first slide groove 41 is formed on the first locking tongue 21, and its length direction is different from the sliding direction of the first locking tongue 21. The nut 12 is rotatably arranged in the housing 11, and a slide shaft 13 is formed on one side of the nut. Figure 1 and Figure 2 As shown, the slide shaft 13 is slidably assembled in the first slide groove 41. When the peach 12 rotates, the slide shaft 13 abuts against the side of the first slide groove 41, driving the first locking tongue 21 to slide into or out of the housing 11. Figure 1 When the first locking bolt 21 is rotated clockwise, the sliding shaft 13 moves upward, and the side surface abuts against the left side of the first sliding groove 41, so as to push the first locking bolt 21 to move leftward and extend out of the housing 11, thereby completing the locking. Figure 1 The paddle 12 is rotated counterclockwise, the slide shaft 13 moves downward, and the side surface abuts against the right side surface of the first slide groove 41, which can push the first locking tongue 21 to move rightward and retract into the housing 11, thereby completing the unlocking.
[0034] When the paddle 12 is rotated to unlock or close the lock, the slide shaft 13 will touch the two ends of the first slide groove 41, generating some noise, so first buffers 31 are provided at the two ends of the first slide groove 41. When the paddle 12 is rotated forward or reverse to the end, the slide shaft 13 will abut against the first buffer 31, and the noise can be significantly reduced compared to direct collision with the first slide groove 41, ensuring that the lock will not have a large noise inside during daily use.
[0035] Please combine Figure 1 and Figure 3 In this embodiment, the two ends of the first slide groove 41 are arc-shaped, and the slide shaft 13 can be relatively stable to approach and stay at this position. Accordingly, the first buffer member 31 is set to an arc-shaped structure with the same shape as the end surface of the first slide groove 41, which can better fit the slide shaft 13 and further reduce the noise generated when the slide shaft 13 moves to the two ends of the first slide groove 41.
[0036] In this embodiment, the first buffer member 31 and the first locking tongue 21 can be connected together by static friction, or can be clamped together, or adhesive can be applied to the contact surface to bond the two together. Figure 3 As shown, the end surface of the first buffer 31 is formed with a connecting portion 33 extending toward the periphery and connected to the side wall of the first locking tongue 21. By providing the connecting portion 33, the contact area between the first buffer 31 and the first locking tongue 21 can be increased, and the firmness of the connection between the two can be improved, so as to prevent the first buffer 31 from falling off from the first sliding groove 41 under the long-term collision of the sliding shaft 13.
[0037] Furthermore, in this embodiment, a second buffer member 32 is also provided in the housing 11 to reduce the collision noise generated when the first locking tongue 21 is retracted into the housing 11. Figure 1As shown, the second buffer 32 is disposed in the housing 11 at a position opposite to the first locking tongue 21. When the first locking tongue 21 moves into the housing 11, the end surface abuts against the second buffer 32, which can also reduce noise compared to direct collision with other limiting structures. Figure 1 In the embodiment, the second buffer 32 is arranged at the right end of the first lock tongue 21. When unlocking, the right end surface of the first lock tongue 21 collides with the second buffer 32. In other embodiments, the second buffer 32 can also be arranged at the upper right or lower right of the first lock tongue 21 to ensure that the two can contact when unlocking to achieve the purpose of reducing noise.
[0038] like Figure 1 As shown, in this embodiment, the peach 12 is rotatably arranged on the column 14 in the housing 11, and a second slide groove 42 having the same length direction as the sliding direction of the first lock tongue 21 is formed on the first lock tongue 21, and the second slide groove 42 is sleeved on the column 14. In this structural form, the first lock tongue 21 is slidably connected with the rotation center axis of the peach 12, which can prevent the first lock tongue 21 from being displaced outside the preset direction when the peach 12 rotates, thereby improving the stability of the linkage between the peach 12 and the first lock tongue 21. Further, a third buffer is provided at both ends of the second slide groove 42. The third buffer can adopt the structural form of the first buffer 31, which can reduce the noise generated by the contact between the two ends of the column 14 and the second slide groove 42.
[0039] In addition, if Figure 1 and Figure 5 As shown, in this embodiment, a second locking tongue 22 is also slidably arranged in the housing 11, and a buffer sleeve 34 is arranged on the side wall of the housing 11 to be opposite to the second locking tongue 22, and a locking tongue hole opposite to the second locking tongue 22 is formed in the middle of the buffer sleeve 34. By providing the buffer sleeve 34, the friction between the second locking tongue 22 and the side wall of the housing 11 can be changed to the friction between the second locking tongue 22 and the buffer sleeve 34, which can significantly reduce the noise generated by the friction. Specifically, the buffer sleeve 34 can be fixedly installed in the through hole on the side wall of the housing 11 to reduce the friction noise generated by the expansion and contraction of the second locking tongue 22.
[0040] Furthermore, if Figure 1 and Figure 5 As shown, a connecting portion 33 extending toward the periphery and connected to the inner wall of the housing 11 is formed at the inner end of the buffer sleeve 34. Similar to the connecting portion 33 on the first buffer member 31, the connecting portion 33 on the buffer sleeve 34 can also improve the firmness between the buffer sleeve 34 and the housing 11, and prevent the buffer sleeve 34 from falling off from the side wall of the housing 11 due to long-term friction of the second locking tongue 22.
[0041] In addition, please combine Figure 6In this embodiment, a third locking tongue 23 is also slidably disposed in the housing 11, and a locking tongue hole opposite to the third locking tongue 23 is formed on the buffer sleeve 34. The third locking tongue 23 slides in the buffer sleeve 34, which can reduce the noise generated by the friction between the third locking tongue 23 and the housing 11 when the third locking tongue 23 is extended and retracted.
[0042] Furthermore, a protruding buffer block 35 is provided on the collision surface of the third lock tongue 23. By providing the buffer block 35, the direct contact between the buckle box in the door frame and the third lock tongue 23 is changed to direct contact between the buckle box and the buffer block 35, which then drives the third lock tongue 23 to move, and can significantly reduce the noise generated by the collision contact between the third lock tongue 23 and the buckle box.
[0043] In this embodiment, the first lock tongue 21 is a square tongue, the second lock tongue 22 is an oblique tongue, and the third lock tongue 23 is a signal tongue. The three are used to achieve different functions. Corresponding buffer structures are set on the three lock tongues, which can reduce the noise of the lock when in use. In other embodiments, the specific models of each lock tongue can be changed, and it only needs to ensure that it has the above-mentioned corresponding buffer structure to achieve the above-mentioned noise reduction function.
[0044] It should be noted that the buffer structures of the first buffer member 31, the second buffer member 32, the third buffer member, the buffer sleeve 34 and the buffer block 35 are made of flexible materials, such as sponge, rubber, plastic, silicone, etc. When they collide or rub against other structures, no obvious noise will be generated. Compared with the case where the buffer structures are not provided, the noise reduction lock can significantly reduce the noise generated during operation.
[0045] 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. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
