The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. It should be noted that in the present disclosure, the terms "including", "configured with", and "set on" are used to express open-ended inclusion and mean that in addition to the listed elements / components / etc., there may be additional elements / components / etc.; the terms "first", "second", etc. are used only as labels and are not intended to limit the number or order of their objects; the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention.
[0022] Unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0023] In this utility model, a noise reduction lock body is disclosed, please refer to Figures 1 to 4 The noise reduction lock body includes a shell 1, a pull rod 2, a lock tongue 3 and a first buffer 4. A lock tongue hole 10 is provided on one side of the shell 1. The pull rod 2 is slidably arranged in the shell 1. The lock tongue 3 is provided on the pull rod 2 and can be extended and retracted along the lock tongue hole 10 to realize opening and closing of the lock. The first buffer 4 is provided on the pull rod 2 along the moving direction of the pull rod 2, on one side close to the lock tongue hole 10 and / or away from the lock tongue hole 10, for offsetting the force of the collision between the lock tongue 3 and the shell 1 and absorbing the noise between the lock tongue 3 and the shell 1. A limit block 5 is correspondingly provided in the shell 1. When the lock tongue 3 extends and / or retracts into the lock tongue hole 10, the first buffer 4 abuts against the limit block 5 to ensure that when the pull rod 2 is toggled to open or close the lock body, no loud noise will be generated between the lock tongue 3 and the shell 1 due to operational collision.
[0024] In some embodiments, the pull rod 2 includes a mounting portion 21, and a first buffer member 4 is disposed on the mounting portion 21. The mounting portion 21 abuts against the limit block 5 through the first buffer member 4 to prevent the mounting portion 21 from colliding with the limit block 5 and generating loud noise. The housing 1 also includes a limit slot 11, along which the mounting portion 21 slides, and the first buffer member 4 is located within the limit slot 11 to prevent the first buffer member 4 from falling off the mounting portion 21 when the mounting portion 21 moves, resulting in the mounting portion 21 colliding with the limit block 5 without the first buffer member 4 to provide a buffer, thereby generating loud noise. Furthermore, the limit blocks 5 are disposed at both ends of the limit slot 11, ensuring that no loud noise is generated between the mounting portion 21 and the limit block 5 due to collision when the noise reduction lock body is opened or closed.
[0025] Furthermore, the first buffer member 4 is annular and is mounted on the mounting portion 21. On the one hand, this simplifies the operation of fixing the first buffer member 4 on both sides of the mounting portion 21. On the other hand, it avoids the first buffer member 4 independently fixed on both sides of the mounting portion 21 from falling off due to continuous movement with the lock tongue 3 and collision with the limit block 5, resulting in failure of noise reduction.
[0026] It can be understood that in some embodiments, the mounting portion 21 is a mounting column, which is formed by extending part of the pull rod 2. The mounting column cooperates with the limit groove 11 to move so that the movement trend of the pull rod 2 in the shell 1 remains stable, and the first buffer member 4 is set on the mounting column; in other embodiments, the mounting portion 21 is a mounting groove. At this time, the first buffer member 4 is set in the mounting groove. At this time, the mounting groove can cooperate with the limit block 5 set on the shell 1 to realize opening and closing, and can also ensure that the movement trend of the pull rod 2 in the shell 1 remains stable, and ensure that no large noise is generated when the lock tongue 3 and the shell 1 collide.
[0027] In order to ensure that the noise reduction lock body does not lose its noise reduction effect when the first buffer member 4 falls accidentally. Figure 2 The noise reduction lock body also includes a second buffer member 6, which is arranged at one end of the limit block 5 facing the pull rod 2, further ensuring that when the noise reduction lock body is opened and closed, the pull rod 2 can always contact the second buffer member 6 with a buffering effect, thereby avoiding the noise reduction lock body from generating loud noise when opening and closing.
[0028] As will be appreciated, the first and second buffer members 4, 6 are silicone rubber members that absorb and mitigate the impact force between the pull rod 2 and the stopper 5, reducing the vibration generated when the noise reduction lock body is opened and closed. Furthermore, the first and second buffer members 4, 6 can also be made of plastic or fiber materials, such as those with a certain degree of elasticity and impact resistance.
[0029] In some embodiments, the noise reduction lock body further includes a paddle assembly 7, which is rotatably disposed within the housing 1 and includes a paddle body 71 and a torsion spring 72. The paddle body 71 is used to drive the pull rod 2 to move to achieve the opening and closing of the noise reduction lock body. The torsion spring 72 twists and drives the paddle body 71 to rotate, causing the lock tongue 3 to pop out of the lock tongue hole 10. A limiting post 12 is provided on the housing 1. One end of the torsion spring 72 is fixed to the housing 1, and the other end of the torsion spring 72 abuts against the paddle body 71. The paddle body 71 is reset and rotated by the action of the torsion spring 72. The torsion spring 72 is reset and rotated until the paddle body 71 abuts against the limiting post 12, further limiting the rotation of the paddle body 71, preventing the torsion spring 72 from rotating too much with the paddle body 71 and thus failing, thereby affecting the service life of the entire noise reduction lock body.
[0030] Further, please refer to Figure 4 The paddle body 71 also includes an extension plate 74, and a corresponding accommodating groove 20 is provided on the pull rod 2. The extension plate 74 extends into the accommodating groove 20. When the paddle body 71 rotates to unlock the noise reduction lock body, the extension plate 74 abuts against the inner wall of the accommodating groove 20 and drives the pull rod 2 to move.
[0031] It can be understood that the end of the extension plate 74 facing the inner wall of the accommodating groove 20 is arc-shaped, thereby ensuring that when the extension plate 74 drives the pull rod 2 to move, the contact surface between the pull rod 2 and the extension plate 74 can move smoothly relative to each other, ensuring the user's unlocking feel and enhancing its usability.
[0032] Furthermore, in some embodiments, a third buffer 13 is provided on the limiting post 12. The third buffer 13 is located at one end of the limiting post 12 near the paddle body 71. When the paddle body 71 rotates and abuts the limiting post 12, the third buffer 13 is used to buffer the collision between the limiting post 12 and the paddle body 71 and absorb and reduce the noise generated by the collision. A limiting plate 73 is formed on the paddle body 71 and can be rotatably abutted against the third buffer 13. The provision of the limiting plate 73 increases the contact area between the paddle body 71 and the third buffer 13, preventing the third buffer 13 from being easily damaged due to only a partial area of contact with the paddle body 71, thereby increasing the service life of the entire third buffer 13.
[0033] It can be understood that in some embodiments, the third buffer member 13 is a buffer sleeve, and the third buffer member 13 is sleeved on the limiting column 12. Similarly, on the one hand, the operation of fixing the third buffer member 13 on the limiting column 12 is simplified. On the other hand, since the third buffer member 13 is used to buffer the collision between the paddle body 71 and the limiting column 12, when the paddle body 71 rotates, the third buffer member 13 that is only separately provided and non-annular may fall off under the drive of the rotation of the paddle body 71, thereby affecting the third buffer member 13.
[0034] In some embodiments, the shell 1 also includes a latch 14 for fixing one end of the torsion spring 72. The direction of the opening slot of the latch 14 is set opposite to the rotation direction of the paddle body 71, so that one end of the torsion spring 72 is restricted from rotating together with the paddle body 71. After the user operates the paddle body 71 to complete the door opening action, the paddle body 71 can return to its original position under the action of the torsion spring 72, locking the noise reduction lock body.
[0035] The present invention provides a noise reduction lock, comprising a buckle box 8 and any of the above-mentioned noise reduction lock bodies, which prevents the lock from being locked when the door is closed due to reasons such as the misalignment of the noise reduction lock body and the buckle box 8. In some embodiments, the lock tongue 3 and the buckle box 8 are provided with corresponding magnetic members 9. The two magnetic members 9 are arranged in opposite directions or the lock tongue 3 is made of magnetic metal. The magnetic member 9 is provided in the buckle box 8. When the user operates the paddle body 71 to unlock the door, the lock tongue 3 moves with the pull rod 2 and is received in the buckle box 8 and the noise reduction lock body. At this time, the pull rod 2 and the lock tongue 3 overcome the magnetic force of the magnetic member 9 under the action of the paddle body 71, thereby unlocking the door. When the unlocking action is completed and the door is no longer unlocked, the noise reduction lock body and the buckle box 8 are aligned. Under the action of the magnetic member 9 in the buckle box 8, the lock tongue 3 extends out of the noise reduction lock body and into the buckle box 8, and remains in the buckle box 8 at all times, completing the locking of the noise reduction lock. And due to the effect of magnetic force, when the noise reduction lock body and the buckle box 8 reach approximate alignment, the lock tongue 3 in the noise reduction lock body tends to approach the magnetic part 9 in the buckle box 8, further driving the alignment between the noise reduction lock body and the buckle box 8, further ensuring the locking effect of the noise reduction lock.
[0036] It will be apparent 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 embodied in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
