Utility model content

The technical problems to be solved in the utility model is to provide, for flexible slide rail, the buffering that a kind of dependable performance is stable Self-closing device.

By solving the technical scheme that above-mentioned technical problem is used: the Self-closed buffer of a kind of flexible slide rail, including Slide, slide fastener and the spring being both connected between base and slide that base and base are slidably matched and resistance Buddhist nun's device, base offers chute, and the end crankle that skids off of the corresponding slide of chute becomes turning, slide fastener to pass through rotating shaft With slide swing be connected and coordinate with slide, slide fastener in the two ends of glide direction respectively formed protrude slide and The projection swung around the shaft, it is characterised in that: the axis hole installing rotating shaft of described slide is set as holding rotating shaft and is sliding There is on the moving direction of seat the elongated hole of mobile space.

On the basis of the above, the hole of the projection skidding off direction in order to accommodating corresponding slide therein, this hole correspondence is sliding Seat skids off the hole wall in direction and is set as when slide fastener puts away turning the swinging track of this projection is formed interference.

On the basis of the above, described hole wall is sliding less than the corresponding slide at turning relative to the angle of the straight trough crankle of chute Enter the angle of the cell wall crankle in direction.

Use the beneficial effect that this utility model is brought: this utility model is by the axle installing slide fastener rotating shaft of slide Hole is set as holding rotating shaft and has the elongated hole of mobile space on the moving direction of slide.So exist when slide fastener padlock During turning, spring can haul slide and move slightly relative to slide fastener, makes accommodating corresponding slide skid off the projection in direction The outside hole wall in hole abuts with this projection, pushes down this projection.Padlock slide fastener around the corner is by both direction phase To power, one is the turning power to sliding part, and one is the hole power to projection of projection, substantially increases Padlock dynamics to slide fastener, can the improper dropout of the most anti-skidproof buckle, thus Promoting Layered Buffer self-closing device maneuverability The reliability and stability of energy.
