Specific embodiment

Below in conjunction with the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts Every other embodiment, fall within the protection scope of the utility model.

As shown in figures 1 to 6, a kind of automatic down slide device of door lock slip lid, including slip lid 2 and brake plate 3 and retreat stop block 5, the two sides of the slip lid 2 slide up and down cooperation by convex-concave slot and 1 two sides of panel, pass through snap-type on 1 two sides of panel Formula is fixed with damping gear 7, and the retreat stop block 5 passes through panel 1, is packed into reset spring 8 in 5 back circular hole of retreat stop block, described multiple Position spring 8 is fixed by the fixed retreat stop block spring leaf 6 of screw 9, and the brake plate 3 is put into 1 front groove of panel, institute It states 3 back side of brake plate to assemble in the middle part of panel 1 and rack gear 4 and fixed with screw 9, the brake plate 3 is slidably mounted on panel On 1,3 lugs position of brake plate covers upper reset spring 8, and integrally is equipped with tooth plate 204 vertically in the slip lid 2, described Tooth plate 204 is engaged with the positive damping gear 7 of panel 1.

The back side integrated setting of the slip lid 2 has the first convex ribs item 201, the second convex ribs item 202 and third convex ribs item 203。

The rack gear 4 is engaged with the damping gear 7 at 1 back side of panel.

Working principle: for slip lid 2 when pulling upward slide by external force, brake plate 3 is by the second convex ribs inside slip lid 2 The Slideslip to the left of item 202, the pressed home spring 8 to the left during the motion of brake plate 3, when Top Runby is more than into slip lid 2 When the second convex ribs 202 highest point of item, brake plate 3 is detached from the lateral compression of 2 the second convex ribs item 202 of inside of slip lid, and is resetted The pressure of spring 8 does opposite direction movement.

If slip lid 2 does not continue to uplink at this time, rack gear 4 is continued reverse direction operation by the pressure of reset spring 8, this When, the second convex ribs item 202 of slip lid 2 is formed with brake plate 3 to be superimposed up and down, stops 2 original place of slip lid, in subtracting for damping gear 7 Under speed, reset spring 8 will be slow that push rack gear 4 and brake plate 3 mobile, thus increase slip lid 2 rest on brake plate 3 when Between, reach the delay feature that 2 middle position of slip lid stops for a long time.Brake plate 3 continues to move downward, when brake plate 3 is completely de- When from 2 second convex ribs item 202 of slip lid, slip lid 2 declines by self gravity.Gear 7 is damped during slip lid 2 is in decline Deceleration, slowly decline, when slip lid 2 drops to the position away from panel 3-5mm or so, the first convex ribs item 201 of slip lid 2 is touched To brake plate 3, the buffering of reset spring 8 and damping gear 7, so that slip lid 2 is declined with slower speed, until dropping to slip lid 2 initial positions achieve the effect that mute noiseless contact surface plate 1.

If slip lid 2 continues uplink at this time, brake plate 3 breaks away to the left by the continuation of third convex ribs item 203 inside slip lid 2 It is dynamic, unclamp external force when being more than to 2 third convex ribs 203 highest point of item of slip lid, at this point, the third convex ribs item 203 of slip lid 2 with brake Plate 3 forms superposition up and down, similarly continues to complete above-mentioned decline process.

If brake plate 3 is more than the highest point of 2 third convex ribs item 203 of slip lid, uplink is continued to, then the tooth in slip lid 2 at this time 204 lower end of plate can touch retreat stop block 5, terminate 2 uplink of slip lid.

Slip lid 2 is slided along 1 groove of panel from top to bottom, and the beveling outside of retreat stop block 5, when the tooth of slip lid 2 When plate 204 is expressed to retreat stop block 5, retreat stop block 5 can squeeze spring sinking, avoid 2 tooth plate 204 of slip lid, be more than when slip lid slides into When retreat stop block 5, reset spring 8 resets retreat stop block 5, installation is completed, after slip lid 2 installs, when pulling outward, due to retreat stop block 5 another sides do not have inclined-plane, and the tooth plate 204 in slip lid 2 will stop sliding after encountering retreat stop block 5.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
