The working principle is as follows: as shown in fig. 3, when the guide rail is closed, the buffer rack is located at the rearmost end of the sliding seat, the relative position of the buffer rack and the sliding seat is in the minimum state, meanwhile, the needle at the tail end of the rebounding slide block 8 is hooked in the needle hanging groove at the tail end of the sliding seat, and the inner rail is locked by the rebounding catching groove 101 on the rebounding slide block, so that when the drawer body moves, the drawer cannot be opened without external force, and the tightness of the closed drawer is maintained.

When the guide rail needs to be opened, as shown in fig. 4, the inner rail is pressed inwards, the inner rail pushes the shifting needle 85 on the rebounding slide block 8 to move backwards through the rebounding buckle 10 on the inner rail, and the rebounding slide block is forced to push the hanging needle to move backwards, so that the hanging needle is separated from the hanging needle groove. At this time, the rebound spring 81 provided between the rebound slider and the slide base 4 pulls the rebound slider to move in the opening direction of the guide rail. Because the inner rail is hung and buckled with the poking needle 85 on the rebounding slide block 8 through the rebounding buckle groove 101 on the rebounding buckle 10, the rebounding slide block tends to push the inner rail to be opened outwards when moving outwards, and the pressing and rebounding opening function of the drawer guide rail is realized. Therefore, when a user operates the drawer provided with the guide rail, the built-in rebounding mechanism can eject the drawer for a certain stroke after lightly pressing the drawer body, and the operation texture of the user is improved.

As shown in fig. 6, during the outward movement of the rebounding slider, the setting pin 85 moves from the self-locking groove 51 to the reset groove 52, wherein, because there is a lateral difference between the track of the reset groove 52 and the track of the self-locking groove 51, when the setting pin 85 moves to the reset groove 52, the setting pin is separated from the rebounding catching groove 101, and the inner rail is opened continuously. When the rebound is over, the user can drag the guide rail outwards to open the guide rail completely. When the guide rail is completely opened, the pushing buckle 9 at the tail end of the inner rail is buckled with the main buckle column 87, and the rebounding frame is pulled to be opened outwards by the power of the outward movement of the inner rail.

As shown in fig. 7, when the guide rail is opened to a certain extent, the push button 9 pulls the resilient frame to be opened to the maximum extent through the main button post 87, and at this time, the driving post 88 at the lower end of the main button post 87 slides from the auxiliary button slot 43 on the guide rail 41 into the release slot 431 and locks the buffer frame, so that the main button post 87 moves laterally, the main button post 87 is separated from the push button 9, and the inner rail is completely opened. After the buffer frame is opened, the tension spring between the buffer frame and the sliding seat is stretched to generate reset power.

As shown in fig. 8, 9 and 10, when the guide rail is closed, the reset buckle groove 111 arranged on the lower end surface of the reset buckle 11 on the inner rail collides with the main buckle post 87 to force the main buckle post 87 to fall off from the separation groove 431 and enter the auxiliary buckle groove 43, the main buckle post 87 is hung and buckled with the reset buckle groove 111 in the deflection process, meanwhile, the shifting needle is hung and buckled with the rebound buckle groove 101, the buffer frame is unlocked, and the inner rail is pulled to be slowly closed under the action of the reset tension spring 6 and the damper 7, so that the buffer reset function when the drawer guide rail is closed is realized. Thereby avoiding the working noise caused by the impact between the drawer panel and the drawer body when the traditional drawer guide rail is closed.

Compared with the prior art, the buffering frame both sides in the present case all are provided with the extension spring that resets, therefore buffering frame during operation, and buffering frame both sides evenly receive the pulling force, can make the smooth and easy stability of buffering frame motion, and simultaneously, the design of two extension springs can provide sufficient power for the buffering resets, makes it can assemble heavy or large-scale drawer and use.

Further: the rebound slider has the advantages that the locking effect when the inner rail is closed and the effect of pushing the inner rail to be opened outwards when the inner rail is rebounded are achieved, two functions are integrated on the rebound slider, compared with the prior art, the structure of the rebound slider is simpler and more compact, the integration degree is high, the development of a drawer guide rail towards miniaturization is facilitated, and the technical defects that the traditional buffering reset guide rail is large in size, complex in structure, bloated in appearance and the like are changed.

Further: compare with traditional drawer guide rail, because the structure in the present case can realize the buffering reset function of drawer, the noise is big when closing that the guide rail that can avoid traditional no buffering function exists, and spacing part receives the striking for a long time and leads to drawbacks such as part damage easily. Meanwhile, the closed drawer is limited by the rebound slider, so that the closed state of the drawer can be kept, the drawer is prevented from being opened under the condition of non-external force operation, and the appearance and neatness of the closed drawer are ensured. In addition, the unique rebound type opening structure is convenient for a user to operate, and meanwhile, the rebound tension spring is adopted for starting, so that the rebound type opening structure has a larger opening stroke. Meanwhile, the rebound tension spring and the releasing and locking structure thereof are simple, the action is efficient, and larger elasticity can be provided for heavy and large-sized drawers, so that the application range is expanded, the rebound tension spring has unique market competitiveness, and the rebound tension spring can be widely popularized and used.
