Buffer self-closing device for telescopic slide rail

Abstract

The invention discloses a buffer self-closing device for a telescopic slide rail, which includes a base, a sliding seat, a sliding buckle, a spring and a damper. The slider is connected to the sliding seat through the rotating shaft and is slidingly matched with the chute. The two ends of the sliding button in the sliding direction respectively form protrusions protruding from the sliding seat and swinging around the rotating shaft. The shaft hole for installing the rotating shaft of the sliding seat is set to be The rotating shaft has an elongated hole with a moving gap in the moving direction of the slide seat. In this way, when the slider is locked at the corner, the spring will pull the slider to move a little relative to the slider, so that the outer hole wall of the hole accommodating the protrusion corresponding to the slide-out direction of the slider abuts against the protrusion, and presses the protrusion. Boss. The sliding buckle locked at the corner is subjected to opposite forces in two directions, which greatly increases the locking force on the sliding buckle, which can effectively prevent the abnormal tripping of the sliding buckle, thereby improving the reliability and stability of the buffer auto-closer's operating performance sex.

Description

technical field [0001] The invention relates to the technical field of buffer self-closing devices for telescopic slide rails. Background technique [0002] The telescopic slide rail is usually equipped with a buffer self-closing device, and the buffer self-closing device is used to realize the buffer self-closing of the drawer. The buffer self-closing device includes a base, a sliding seat that is slidably matched with the base, a sliding buckle, and a spring and a damper that are connected between the base and the sliding seat. The outlet end turns into a corner, and the slider is connected to the sliding seat through the rotating shaft and slidingly matched with the chute. The two ends of the sliding button in the sliding direction respectively form protrusions protruding from the sliding seat and swinging around the rotating shaft. The buffer self-closing device is installed on the outer rail, and the inner rail has a pull hook that can be stuck between the two ends of ...

Problems solved by technology

Obviously, the strength of the buckle is not enough. Usually, the angle of the corner of the chute should not be too large, so that it can be unbuckled when the hook collides with the slider. When the drawer is opened, the sliding buckle that must be locked at the corner has been released and slipped away from the corner, causing the drawer to fail to close automatically
