A new type of silent buffering mechanism

Abstract

The present invention discloses a novel silent buffering mechanism, which includes a buffer seat, a buffer pulling spring and a buffer slider. The buffer slider is slidably clamped on the buffer seat. A buffer pulling spring is fixed on the side wall of the buffer slider for pulling the silent chute rib frame to move in the opposite direction along the direction of the bayonet slide rail. A corner slide rail bent towards the side is provided at the end of the bayonet slide rail. The bayonet slide rail and the corner slide rail are connected. Two silent chute rib frames are fixed at the end of the corner slide rail. The direction in which the silent chute rib frames are arranged is connected with the extending direction of the end of the corner slide rail. The top surface of the silent chute rib frame is an inclined surface that slopes upward. A silent sliding pad that fits and contacts the inclined surface is fixed on the bottom surface of the buffer slider. The present invention can reduce the impact force of the buffer slider directly hitting the bayonet of the bayonet slide rail, and the corner discharges the force through frictional contact with the inclined surface, greatly reducing the noise during the use of the drawer and improving the overall use experience of the drawer slide rail.

Description

Technical Field

[0001] The present invention specifically relates to a silent mechanism for a drawer slide rail, specifically a new silent buffer mechanism. Background Art

[0002] When the drawer is opened, when the slider on the existing buffer of the slide rail enters the position of the buffer seat bayonet, it will violently impact the bayonet, generating a relatively large noise and affecting the use experience of the slide rail.

[0003] Therefore, for such problems, we need a silent buffer mechanism that can prevent the slider from directly colliding with the bayonet and can effectively reduce the overall noise of the slide rail and improve the use experience of the drawer. Summary of the Invention

[0004] The purpose of the present invention is to provide a new silent buffer mechanism to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A new silent buffer mechanism includes a buffer seat, a buffer spring, and a buffer slider. A bayonet slide rail is provided on the buffer seat, and the buffer slider is slidably clamped on the bayonet slide rail. A buffer spring for pulling the silent chute rib frame to move in the opposite direction along the bayonet slide rail is fixed on the side wall of the buffer slider. At the end of the bayonet slide rail, a corner slide rail bent towards the side is provided, and the bayonet slide rail communicates with the corner slide rail. Two silent chute rib frames are fixed at the end of the corner slide rail, and the direction of the silent chute rib frames is the same as the extension direction of the end of the corner slide rail. The top surface of the silent chute rib frame is an inclined surface sloping upwards, and a silent sliding pad that fits and contacts the inclined surface is fixed on the bottom surface of the buffer slider.

[0007] As a further solution of the present invention: A spring groove is provided on the buffer seat, the buffer spring is entirely sunk in the spring groove, one end of the buffer spring is fixed on the groove wall of the spring groove, and the other end of the buffer spring is rotationally hooked on a spring hook, and the spring hook is fixed on the side wall of the buffer slider.

[0008] As a further solution of the present invention: In the normal elastic deformation state of the buffer spring, the buffer slider is located at the head end of the bayonet slide rail on the side away from the corner slide rail.

[0009] As a further solution of the present invention: A plurality of slide rail clamping rods are fixed on the bottom surface of the buffer slider, and the slide rail clamping rods are vertically slidably clamped in the bayonet slide rail.

[0010] As a further solution of the present invention: a buffer oil cylinder parallel to the buffer spring is provided on the buffer seat. The buffer oil cylinder is stuck in the oil cylinder frame groove, and the oil cylinder frame groove is fixed on the buffer seat. The telescopic end of the buffer oil cylinder is fixed with an oil cylinder head, and the head end of the oil cylinder head is fixed on the side wall of the rotating block. The whole rotating block is integrally and rotatably fixed on the side wall of the buffer slider opposite to the oil cylinder head.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: when the buffer slider slides on the bayonet slide rail and is about to hit the end of the bayonet slide rail, the buffer slider will rotate integrally through the corner slide rail and cooperate with the silent chute rib frame and the silent sliding pad at the bottom of the buffer slider for inclined plane friction contact, reducing the impact force of the buffer slider directly hitting the bayonet of the bayonet slide rail. The corner relieves the force through inclined plane friction contact, greatly reducing the noise during the use of the drawer and improving the overall use experience of the drawer slide rail.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figures 1 to 5 In the embodiment of the present invention, a new type of silent buffer mechanism includes a buffer seat 1, a buffer spring 3 and a buffer slider 4. A bayonet slide rail 12 is provided on the buffer seat 1, and the buffer slider 4 is slidably clamped on the bayonet slide rail 12. A buffer spring 3 for pulling the silent slide groove rib frame 14 to move in the opposite direction along the bayonet slide rail 12 is fixed on the side wall of the buffer slider 4. A bent corner slide rail 13 is provided at the end of the bayonet slide rail 12 and bends towards the side. The bayonet slide rail 12 is communicated with the corner slide rail 13. Two silent slide groove rib frames 14 are fixed at the end of the corner slide rail 13. The direction of the silent slide groove rib frame 14 is communicated with the extending direction of the end of the corner slide rail 13. The top surface of the silent slide groove rib frame 14 is an inclined surface that slopes upward. A silent slide pad 43 that fits and contacts the inclined surface is fixed on the bottom surface of the buffer slider 4.

[0022] A spring groove 11 is provided on the buffer seat 1. The buffer spring 3 is entirely sunken in the spring groove 11. One end of the buffer spring 3 is fixed on the groove wall of the spring groove 11, and the other end of the buffer spring 3 is rotatably hooked on a spring hook 40. The spring hook 40 is fixed on the side wall of the buffer slider 4. The buffer spring 3 being sunken in the spring groove 11 can prevent the buffer spring 3 from popping out. The buffer spring 3 is rotatably hooked to the buffer slider 4 through the spring hook 40, ensuring that there is a certain amount of rotation reserved between the buffer spring 3 and the buffer slider 4. When the buffer slider 4 rotates along the corner slide rail 13, the buffer spring 3 can flexibly follow the buffer slider 4 for a small-angle rotation.

[0023] When the buffer spring 3 is in a normal elastic deformation state, the buffer slider 4 is located at the head end of the bayonet slide rail 12 on the side away from the corner slide rail 13. When the drawer is pulled out, the entire buffer seat 1 slides, and the buffer slider 4 will slide towards the corner slide rail 13 at the end of the bayonet slide rail 12. At this time, the buffer spring 3 stretches the buffer slider 4 to reduce the impact of suddenly pulling the buffer seat 1 and reduce the impact force of the buffer slider 4 hitting the end of the bayonet slide rail 12. At the same time, when the buffer seat 1 is not pulled, the buffer spring 3 can pull the buffer slider 4 back into place.

[0024] A plurality of slide rail clamping rods 42 are fixed on the bottom surface of the buffer slider 4. The slide rail clamping rods 42 are vertically slidably clamped in the bayonet slide rail 12. The buffer slider 4 is slidably clamped to the bayonet slide rail 12 through the slide rail clamping rods 42. When the buffer slider 4 moves to the corner slide rail 13 at the end of the bayonet slide rail 12, the slide rail clamping rods 42 will also slide into the corner slide rail 13.

[0025] The working principle of the present invention is as follows: During operation, when the buffer slider 4 slides on the bayonet slide rail 12 and is about to hit the end of the bayonet slide rail 12, the buffer slider 4 will rotate as a whole through the corner slide rail 13 and cooperate with the silent chute rib frame 14 and the silent slide pad 43 at the bottom of the buffer slider 4 for inclined plane friction contact, reducing the impact force of the buffer slider 4 directly hitting the bayonet of the bayonet slide rail 12. The corner dissipates force through inclined plane friction contact, greatly reducing the noise during the use of the drawer and improving the overall use experience of the drawer slide rail.

[0026] Embodiment 2

[0027] Please refer to Figures 1 to 6 , the difference between this embodiment and Embodiment 1 is that:

[0028] A buffer oil cylinder 2 parallel to the buffer spring 3 is provided on the buffer seat 1. The buffer oil cylinder 2 is stuck in the oil cylinder frame groove 10, and the oil cylinder frame groove 10 is fixed on the buffer seat 1. The telescopic end of the buffer oil cylinder 2 is fixed with an oil cylinder head 20, and the head end of the oil cylinder head 20 is fixed on the side wall of the rotating block 5. The whole rotating block 5 is integrally rotatably fixed on the side wall of the buffer slider 4 opposite to the oil cylinder head 20.

[0029] A block rotating groove 41 with an opening opposite to the oil cylinder head 20 is formed on the panel of the buffer slider 4 opposite to the oil cylinder head 20. The rotating block 5 is horizontally rotatably stuck in the block rotating groove 41, and the oil cylinder head 20 is fixed on the vertical end surface of the rotating block 5 extending out of the block rotating groove 41. The provided buffer oil cylinder 2 can form a double buffer with the buffer spring 3. When the main buffer spring 3 rebounds to the normal deformation state, in order to prevent the buffer slider 4 from hitting the head end of the bayonet slide rail 12, the buffer spring 3 assists in buffering the return of the buffer slider 4 to achieve the effect of buffering and damping to close the drawer. At the same time, in order to adapt to the overall corner of the buffer slider 4 for silent buffering, the oil cylinder head 20 and the buffer slider 4 can achieve horizontal rotation through the rotating block 5 to ensure the normal connection relationship between the oil cylinder head 20 and the buffer slider 4.
