The rear end of the rebound hanging buckling rail 75 is also provided with a rebound derailing 79, and the rebound derailing 79 is obliquely arranged towards the rebound shifting block 6.

The working principle is as follows: as shown in fig. 5 and 6, when the guide rail is in the closed state, the rebounding hanging block 12 is hung and buckled on the rebounding hanging buckle rail 75, so that the rebounding tension spring 82 is in the tight state, and the shifting needle 5 on the outer rail is hung and buckled with the resetting hanging groove 93, so that the guide rail is prevented from being opened by itself, the tightness of the drawer in the closed state is maintained, and the tidiness and the attractiveness of the drawer after the drawer is closed are maintained while dust and other sundries are prevented from entering the drawer.

As shown in fig. 7, when a user needs to open the drawer, the user presses the drawer backwards, the drawer forces the outer rail to move backwards, the reset slider, the reset hanging block and the rebounding slider 10 are pushed to move backwards by the shifting needle 5 on the outer rail, when the rebounding slider 10 moves backwards, the rebounding seat 11 on the rebounding slider 10 pushes the rebounding hanging block 12 to move backwards, so that the rebounding sliding column 123 on the rebounding hanging block 12 is in contact with the rebounding derailing 79, and the rebounding hanging block 12 is forced to deflect by the guiding action of the rebounding derailing 79 and is separated from the rebounding hooking rail 75, so that the locking action on the rebounding slider 10 is released. When the user releases his hand, the rebound tension spring pulls the rebound slider 10 to move forward, and pushes the reset slider and the reset hanging block to open outward, so that the reset hanging block pulls the shifting needle 5 and the outer rail to rebound outward to open.

As shown in fig. 8 and 9, when the reset hanging block 9 moves from the reset guide rail 72 to the reset derail 73, the reset hanging block 9 deflects to force the reset hanging groove 93 to separate from the setting needle 5, and the outer rail is continuously opened forwards.

Wherein, it is required to be noted that: after the guide rail is closed, the rebounding shifting block 6 is located at the rear end of the rebounding hanging block 12, so that when the guide rail needs to be completely opened, the rebounding shifting block 6 will collide with the rebounding hanging block, and therefore the tripping slide rail 62 is ingeniously arranged at the bottom of the rebounding shifting block 6 in the scheme, and the head end and the tail end of the tripping slide rail 62 are communicated with the side wall of the rebounding shifting block 6. When the guide rail is opened, the rebounding shifting block 6 is in contact with the rebounding shifting block 6, the rebounding guide post 122 on the top of the rebounding shifting block 6 enters the tripping slideway 62 to force the rebounding shifting block 6 to deflect, and the rebounding guide post 122 enters the tripping slideway 62 and then is separated from the rear end of the rebounding guide post, so that the influence of interference between the rebounding shifting block 6 and the rebounding hanging block 12 on normal opening of the guide rail is avoided.

As shown in fig. 10, when the user closes the guide rail, the outer rail moves backward, the rebounding block 6 on the outer rail first contacts the rebounding guide post 122 on the rebounding block 12, but the inclined pushing surface 61 of the side wall of the rebounding block 6 contacts the rebounding guide post 122 and prevents it from entering the trip slide 62, when the rebounding block 6 continues to move backward, the inclined pushing surface 61 pushes the rebounding guide post 122 to move backward along the rebounding guide rail 74, at this time, the front end of the rebounding block 12 is pressed against the support base 112, and the downward swinging stroke of the rear end of the rebounding block 12 is limited, so that the rebounding block 12 can only move backward and drive the rebounding slider 10 to move backward, and when the rebounding guide post 122 moves from the rebounding guide rail 74 to the rebounding catch rail 75, the rebounding block 12 is caught in the rebounding catch rail 75, the rebounding block 6 is separated from the rebounding block 12, and the guide rail can continue to be closed. When the rebound slider moves backwards, the rebound tension spring and the reset tension spring are simultaneously stretched. Prepare for the buffer reset and rebound opening of the guide rail.

As shown in fig. 11, when the outer rail is closed to a certain distance, the shifting needle 5 on the outer rail collides with the reset hanging block 6 to force the reset hanging block to deflect, so that the reset hanging block enters the reset guide rail 72 from the reset derailment 73, and the reset hanging groove 93 is butted with the shifting needle 5, the reset hanging block resets under the pulling of the reset tension spring, and the outer rail is forced to slowly move to a closed state by the action of the buffer cylinder, thereby realizing the buffer reset closing function when the drawer is closed.

Compared with the traditional drawer guide rail, due to the unique rebound opening structure design, the buffering reset closing and rebound opening of the guide rail can be realized by using the shifting needle of the outer rail. The rebounding shifting block 6 on the outer rail is used for pushing the rebounding mechanism to reset. Therefore, the outer rail in the scheme only needs to be provided with two components and has the buffer function, the reset buffer function when the guide rail is closed and the pressing rebound opening function when the guide rail is opened can be realized, the functions are realized, the product structure is simplified, the working efficiency is higher, the production cost is reduced, the product working stability is provided, and the outer rail can be widely popularized and used.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and the above-described embodiments and descriptions are only illustrative of the principles of the present invention, and that various changes and modifications, such as the driving manner of the rebound slider, the specific form and installation position of the rebound spring, etc., may be made without departing from the spirit and scope of the present invention, and these changes and modifications are within the scope of the claimed invention.
