[0030] 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.

[0031] In this embodiment, a buffer structure and a lock having the same are disclosed. Please refer to Figures 1 to 3 The buffer structure 2 is provided in the signal tongue assembly of the lock. When the signal tongue assembly is in operation, the buffer structure 2 can reduce collision and friction noise.

[0032] Please refer to Figure 2 and Figure 3The buffer structure 2 includes a mounting portion 21 and an impact portion 22, wherein the mounting portion 21 is an arc-shaped structure and can be installed in an arc-shaped groove to be fixed in a limited position. The impact portion 22 is arranged at the two ends of the mounting portion 21, and a collision surface is formed at the front end. The buffer structure 2 is made of a flexible material, and when it is hit during use, it can absorb part of the impact energy and reduce the collision noise. In addition, since the mounting portion 21 is an arc-shaped structure, when the collision surfaces at both ends are hit, the mounting portion 21 can produce a certain deformation, and can also achieve the buffering and noise reduction function.

[0033] As an embodiment, the width of the impact portion 22 in the buffer structure 2 is greater than the width of the mounting portion 21. When the mounting portion 21 is set in the groove, the wider impact portion 22 can further limit the movement of the mounting portion 21 along the extending direction of the groove, making the buffer structure 2 more firm and stable.

[0034] As an embodiment, an arc-shaped guide surface 23 is formed between the side surface of the impact portion 22 and the collision surface in the buffer structure 2. When the buffer structure 2 is applied to a rotatable component, there is friction between the collision surface and other components during the rotation of the component. After the guide surface 23 is provided, the friction resistance can be significantly reduced, thereby reducing the friction noise.

[0035] The lock in this embodiment mainly includes a housing 1, a first component 11, a second component 3 and the above-mentioned buffer structure 2. The housing 1 is formed by buckling two half shells and is used to accommodate other structures. Figure 1 Only one of the half shell structures is shown in the figure. The first member 11 is arranged on the housing 1, and the second member 3 is slidably arranged in the housing 1 and opposite to the first member 11. A mounting groove 33 is formed on the second member 3, and the mounting portion 21 of the buffer structure 2 is arranged in the mounting groove 33, so that the buffer structure 2 can be fixed on the second member 3. When the second member 3 slides toward the first member 11, the impact portion 22 can abut against the second member 3, thereby reducing the noise generated by the collision between the first member 11 and the second member 3.

[0036] As an embodiment, the second member 3 includes a first body 31 and a second body 32, wherein the first body 31 is slidably disposed in the housing 1, the second body 32 is rotatably connected to the first body 31, and the mounting groove 33 is disposed on the second body 32 and is located at the periphery of the rotation axis of the second body 32; wherein the width of the impact portion 22 is greater than the width of the mounting portion 21. When the impact portion 22 abuts against the first member 11, if the second body 32 rotates, the collision surface will generate friction with the first member 11, and the wider impact portion 22 can prevent the buffer member from moving along the extension direction of the mounting groove 33, so that the buffer member can operate stably and maintain the noise reduction effect.

[0037] Furthermore, an arc-shaped guide surface 23 is formed between the side surface of the impact part 22 and the collision surface. Therefore, when the impact part 22 abuts against the first member 11 and the second body 32 rotates, the friction between the impact part 22 and the first member 11 can be reduced by means of the arc-shaped guide surface 23, thereby reducing the friction noise generated in the process.

[0038] In a specific embodiment, Figures 1 to 3 As shown, the second component 3 is a signal tongue assembly, the first body 31 is a slide rod, and the second body 32 is a signal tongue; the first component 11 is a side wall of the shell 1, and a lock tongue hole for the signal tongue to pass through is formed on the side wall, and the mounting groove 33 is arranged opposite to the outer peripheral side wall of the lock tongue hole.

[0039] The slide bar is slidably arranged in the limit plate 12 in the housing 1, the signal tongue is rotatably connected to the left end of the slide bar, and the signal tongue is opposite to the lock tongue hole on the side wall. When the signal tongue assembly slides, the signal tongue extends from the lock tongue hole or retracts into the housing 1. The mounting groove 33 is opposite to the peripheral side wall of the lock tongue hole, so the buffer structure 2 therein can be against the peripheral side wall of the lock tongue hole when the signal tongue assembly slides, and the signal tongue assembly is limited while the collision noise can be reduced.

[0040] During the unlocking and locking process, the signal tongue is pushed by the buckle box of the door frame to produce a certain rotation. At this time, the impact part 22 and the side wall of the shell 1 produce friction. With the help of the arc-shaped guide surface 23, the friction between the impact part 22 and the side wall can be reduced, thereby reducing the friction noise generated in the process.

[0041] It should be noted that the buffer structure 2 is an arc-shaped component, which is arranged on the outer periphery of the signal tongue rotating axis, that is, it is arranged circumferentially around the axis. Therefore, when the signal tongue rotates forward and backward, there is an impact portion 22 that can frictionally contact the side wall and reduce noise with the help of the arc-shaped guide surface 23.

[0042] Furthermore, in this embodiment, both upper and lower ends of the signal tongue are provided with mounting grooves 33 and buffer structures 2, which can improve the buffering and noise reduction effect.

[0043] In addition, in this embodiment, a first buffer member 4 is also provided on the signal tongue. Figure 2 As shown, the end surface of the first buffer member 4 protrudes from the collision surface of the signal tongue. When the signal tongue contacts the buckle box of the door frame, the collision noise can be reduced.

[0044] The above noise reduction process is explained by taking the signal tongue assembly and the side wall of the housing 1 as the second component 3 and the first component 11 as examples respectively. It should be added that there are many types of components that can produce collision and friction in the lock, such as the square tongue assembly, the oblique tongue assembly, the peach assembly, various transmission rods, etc., which may collide or rub with each other or with the housing. After the above buffer structure 2 is set between the two components, the noise reduction effect can also be produced. Therefore, the above first component 11 and the second component 3 should not be limited to the side wall of the housing and the signal tongue assembly.

[0045] As an embodiment, the lock of this embodiment is further provided with a tongue assembly 5 and a second buffer member 6. Figure 1 As shown, the tongue assembly 5 is slidably disposed in the housing 1, and the outer end can slide to the outside of the housing 1 through the lock tongue hole. The second buffer 6 is disposed in the housing 1 at a position opposite to the inner end of the tongue assembly 5, wherein when the tongue assembly 5 slides into the housing 1, the inner end abuts against the second buffer 6. The collision noise of the tongue assembly 5 during operation can be reduced.

[0046] It should be noted that the buffer structure 2, the first buffer member 4 and the second buffer member 6 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 lock without the buffer structure 2, the lock can significantly reduce the noise generated during operation.

[0047] 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.
