Sliding seat positioning device for drawer slide

The invention relates to a fastener for a drawer slide device, in particular to a sliding seat positioning device for a drawer slide.

As shown in FIG. 8 and FIG. 9 , it is a conventional drawer slide device 70 . The slide rail device 70 includes a first slide rail 71 , a slide base 72 and a second slide rail 73 . The slide rail 71 has a first axial end 710 at the center thereof, and the first slide rail 71 is provided with a positioning member 711 at the first end 710. The positioning member 711 is formed at the front end. The sliding seat 72 is slidably disposed in the first sliding rail 71. A sliding slot 72 is provided at a position corresponding to the first end 710 of the sliding base 72. When the sliding seat 72 slides When the position of the first end 710 of the first sliding rail 71 is reached, the slot 721 of the sliding seat 72 will be buckled by the positioning member 711 without slipping, and the second sliding rail 73 is inside. The side surface 730 is correspondingly and slidably disposed on the sliding seat 72. The inner side surface 730 of the second sliding rail 73 is provided with a releasing member 731. When the second sliding rail 73 is slid to the first sliding rail 71, The first end 710, the release member 731 will press against the positioning member 711 and push outwardly, so that the positioning member 711 is disengaged from the slot 721 of the sliding seat 72, so that the sliding seat 72 is released. Positioning state.

Since the conventional drawer rail device 70 has the following problems in use:

1. The positioning member 711 is disposed only on a single side of the first sliding rail 71, so that the sliding seat 72 is fastened in a state of single-sided contact force, and the structural strength of the positioning member 711 is insufficient. It is easy to make this for a long time. The positioning member 711 is deformed, and it is easy to cause the unhooking condition only by the one-side snap.

2. The required displacement amount of the positioning member 711 when the positioning is released is large, which causes the user to be more laborious when pushing and unscrewing the unlocking member 731 of the second sliding rail 73.

Based on the above problems, there is a need to improve and strengthen.

In order to solve the problem that the positioning member of the conventional drawer rail device is unilaterally stressed and the structural strength is insufficient, and deformation and decoupling are easy to occur, and the positioning is difficult, the main purpose of the present invention is to provide a drawer slide rail. The sliding seat positioning device, wherein the positioning fastener is buckled by the lower side of the sliding seat, and is disengaged by pressing the pressing block and the contact fastener above and below, which is labor-saving and not easy to damage. .

The technical method of the present invention is to provide a sliding seat positioning device for a drawer slide rail, which is disposed between a first sliding rail and a second sliding rail slidably disposed with the first sliding rail, including a positioning fastener is fixedly disposed on an inner bottom surface of the first sliding rail adjacent to an open end, and the positioning fastener comprises a spring clip piece that can be pulled up and down, and the elastic buckle piece is upwardly convex. a sliding block is disposed; a sliding seat is slidably disposed between the first sliding rail and the second sliding rail, and the sliding seat is attached to the bottom surface of the open end of the first sliding rail a fastening hole is formed, and the fastening hole is corresponding to the buckle piece fastened to the elastic piece; a pressing block is fixedly disposed on the inner bottom surface of the second sliding rail, and the pressing block can be combined with The positioning fastener is relatively pressed, and the elastic piece is pressed downward and inclined.

The sliding seat positioning device of the above-mentioned drawer slide, wherein the positioning fastener further comprises a fixing portion fixedly disposed on an inner bottom surface of the first sliding rail, and a central portion of the fixing portion is opened An opening, the elastic piece is connected to a side corresponding to the opening along one end of the first sliding rail, so that the unattached portion of the elastic piece is hollowed out and can be The upper and lower sides of the opening are pulled.

The sliding seat positioning device of the drawer slide, wherein the elastic piece and the opening are in a corresponding T shape, the opening is oriented in a horizontal end toward the open end of the first sliding rail to The vertical end faces away from the open end and is parallel to the axis of the first slide rail. The latching piece is correspondingly disposed in the opening, and is connected to the side of the opening by an end extending in the axial direction. The other side of the elastic piece that is not connected is hollowed out.

The sliding seat positioning device of the above-mentioned drawer slide rail, wherein the positioning fastener protrudes along the side line respectively on the two sides of the elastic buckle piece, and a pressing block is respectively protruded from the two sides, and the pressing block is respectively convexly formed to correspond to Two convex portions of the two pressing blocks of the elastic piece, the pressing block is capable of pressing the two convex portions relative to the two pressing blocks of the elastic piece.

The invention utilizes the sliding seat positioning device of the provided drawer slide rail, and the power enhancements that can be obtained include:

1. The positioning fastener of the present invention is disposed on the inner rail surface of the first sliding rail, and is provided with an elastic buckle on the positioning fastener to buckle the sliding seat, and the sliding seat and the buckle of the elastic buckle are limited to be fastened. And the amount of displacement required when the buckle is small is small, and it is not easy to cause a single point of force, which causes a problem of a decrease in service life and an easy release.

2. The press block of the present invention is disposed on the inner side of the second slide rail and is positioned with the buckle The pieces are arranged in opposite directions. When the second sliding rail slides to the position where the first sliding rail is provided with the positioning fastener, the pressing block is pressed from top to bottom in a surface contact manner, so that the positioning fastener is released from the buckle positioning. It allows the user to save effort when pushing and pulling the second slide rail to release the positioning.
