Description

The Self-closed buffer of flexible slide rail

Technical field

The present invention relates to the Self-closed buffer technical field of flexible slide rail.

Background technology

Flexible slide rail is usually mounted with Self-closed buffer, realizes buffering from pass in drawer using Self-closed buffer.Buffering is certainly Close device and include slide, slide fastener and the spring being both connected between base and slide and resistance that base and base are slidably matched Buddhist nun's device, chute is offered on base, the corresponding slide of chute skids off end crankle into turning, and slide fastener passes through rotating shaft and swung with slide Connect and coordinate with slide, slide fastener forms protrusion slide and the projection swung around the shaft respectively in the both ends of glide direction. Self-closed buffer is arranged on outer rail, and interior rail has the drag hook between the both ends projection that may be stuck in slide fastener.When pulling out drawer, with drawer Fixed interior rail pulls slide fastener to drive slide to skid off by drag hook, and when slide fastener slides into turning, the sliding part of slide fastener can turn in Turning, slide fastener is driven to swing around the shaft, now the corresponding preceding projection for skidding off direction can put away drag hook, no longer block drag hook, Drag hook is able to depart from slide fastener, can then continue to pull out drawer, slide fastener now is padlock under the elastic force effect of spring at turning Place.When pushing back drawer, drag hook can collide the corresponding posterior projection for slipping into direction, drive the sliding part of slide fastener to put away turning Trip, now posterior projection can be flapped toward drag hook, between drag hook is stuck in two projections again, under the elastic pulling force effect of spring, Slide fastener back slips into, by drag hook pull in rail and drawer slip into, while under the damping action of damper, drawer is slowly to close Close, so as to realize the buffering of drawer from pass.

Traditional Self-closed buffer is typically to be set as matching with the size of rotating shaft by the size of the axis hole on the slide.It is true On, such design is defective, and padlock is easy to that improper dropout phenomenon occurs in the slide fastener of the corner of chute, causes Self-closed buffer can not normal operation.Reason is that axis hole matches with rotating shaft size, therefore can not possibly be subjected to displacement between the two, That is can not possibly be subjected to displacement between slide fastener and slide, so when slide fastener padlock is at turning, spring hauls slide, sliding Seat heads on slide fastener, the sliding part of slide fastener is stuck in corner, and sliding part now is the slide side of slipping into corresponding with corner To inner side cell wall abut, with this abut against caused by frictional force padlock is carried out to sliding part.Obviously the dynamics of this padlock is Inadequate, the angle of the turning crankle of usual chute can not be excessive, is tripped when colliding slide fastener in order to drag hook, also there is slip Portion easily improper dropout the problem of, cause originally in the state of pulling the drawer out, it is necessary to which the slide fastener of padlock around the corner is just Thread off and turning of slipping away, cause drawer can not be normally from pass.

The content of the invention

The technical problem to be solved in the present invention is to provide a kind of dependable performance stable Self-closed buffer for the slide rail that stretches.

Technical scheme used by solve above-mentioned technical problem：A kind of Self-closed buffer of flexible slide rail, including base, Slide, slide fastener and the spring and damper being both connected between base and slide being slidably matched with base, open up on base There is chute, the corresponding slide of chute skids off end crankle into turning, and slide fastener swings connection by rotating shaft and slide and slided with chute Dynamic to coordinate, slide fastener forms protrusion slide and the projection swung around the shaft respectively in the both ends of glide direction, it is characterised in that：It is described The axis hole of the installation rotating shaft of slide is set as that the elongated hole that rotating shaft has mobile space on the moving direction of slide can be held.

On the basis of the above, the hole of the projection therein that direction is skidded off to accommodating corresponding slide, the hole corresponds to slide cunning The hole wall of outgoing direction is set as forming interference to the swinging track of the projection when slide fastener puts away turning.

On the basis of the above, the hole wall is less than the corresponding slide side of slipping at turning with respect to the angle of the straight trough crankle of chute To cell wall crankle angle.

Using beneficial effect caused by the present invention：The axis hole of the installation slide fastener rotating shaft of slide is set as holding by the present invention to be turned Axle has the elongated hole of mobile space on the moving direction of slide.So when slide fastener padlock is at turning, spring can haul cunning Seat slightly, makes accommodating corresponding slide skid off the outside hole wall in the hole of the projection in direction and abutted with the projection, pressed relative to slide fastener movement The firmly projection.The slide fastener of padlock around the corner is by the relative power of both direction, and one is power of the turning to sliding part, and one is The hole of projection substantially increases the padlock dynamics to slide fastener to the power of projection, can effectively anti-skidproof buckle improper dropout, from And the reliability and stability of Promoting Layered Buffer self-closing device runnability.

Embodiment

As Figure 1-4, a kind of Self-closed buffer of flexible slide rail, including the slide that base 1 and base 1 are slidably matched 2nd, slide fastener 3 and the spring 4 and damper 5 that are both connected between base 1 and slide 2, chute 11, chute are offered on base 1 11 corresponding slide 2 skids off end crankle into turning 11.1, slide fastener 3 by rotating shaft 31 and slide 2 swing connection and with chute 11 It is slidably matched, slide fastener 3 forms protrusion slide 2 and around the shaft 31 projection 32,33 swung respectively in the both ends of glide direction, wherein Corresponding slide 2 skid off direction for projection 32, corresponding slide 2 slip into direction for projection 33.In the present invention, the slide 2 The axis hole 21 of installation rotating shaft 31 be set as holding rotating shaft 31 there is the elongated hole of mobile space on the moving direction of slide 2.This Sample, when the padlock of slide fastener 3 is at turning 11.1, spring 4 can haul slide 2 and the hole for slightly, making accommodating projection 32 is moved relative to slide fastener 3 The hole wall a that 22 corresponding slide 2 skids off direction abuts with the projection 32, pushes down the projection 32.Cunning of the padlock at turning 11.1 For button 3 by the relative power of both direction, one is that the corresponding slide at turning 11.1 slips into the inner side cell wall b in direction to slide fastener 3 The power of sliding part 34, one be hole 22 power of the outside hole wall a to projection 32, both jointly to slide fastener 3 carry out padlock, greatly Add the padlock dynamics to slide fastener 3, can effectively anti-skidproof buckle 3 improper dropout.

For the improper dropout of further anti-skidproof buckle 3, and further provide smooth degree that slide fastener 3 runs and Stability, the operation noise of slide fastener 3 is reduced, the hole 22 that corresponding slide 2 skids off the projection 32 in direction can be housed therein, Make the hole correspond to slide 2 and skid off the hole wall a in direction to be set as when slide fastener 3 puts away turning 11.1 to the swinging track shape of the projection 32 Into interference, the sliding part 34 of slide fastener 3 of the padlock at turning 11.1 is prevented to be swung up, so as to further prevent slide fastener 3 non- It is normal to thread off.Specifically, the corresponding slide that the hole wall a is less than turning 11.1 with respect to the angle of the straight trough crankle of chute 11 can be set Slip into the angle of the cell wall b crankles in direction, that is to say, that hole wall a and cell wall b is not parallel, and distance between the two is along cunning The direction that dynamic portion 34 puts away turning 11.1 gradually zooms in.Sliding part 34 is to put away turning 11.1, it is necessary to which enough external force is come Overcome the pulling force of spring, such as the collision of drag hook.And during whole put away, the resistance suffered by sliding part 34 is basic It is invariable, thus smoothness and stability that sliding part 34 puts away turning 11.1 when tripping can be lifted, cunning can be reduced The operation noise of button 3.And the slide fastener of traditional Self-closed buffer is that frictionally dead point padlock around the corner, rubs extremely once overcoming Point, slide fastener will put away turning suddenly, produce operation noise.
