Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, the Self-locking type lower-nest of the utility model parachute kit is slidably socketed in umbrella shaft 1, and it comprises: lower nest main body 2, outer sleeve 3 and movable part 5.As shown in Figure 3 and Figure 4, described umbrella shaft 1 sidewall offers a parachute-opening locating hole 11 for locating lower nest main body 2 in parachute-opening position.Described lower nest main body 2 is slidably socketed in umbrella shaft 1, and its top is provided with the ring nest portion 22 of evagination for connecting each group of umbrella frame 6, and its underpart sidewall is offering a square through hole 21 with corresponding position, described parachute-opening locating hole 11 position.Described movable part 5 axle is connected to through hole 21 place of lower nest main body 2 sidewall.It is outer and can slide up and down in certain stroke range that described outer sleeve 3 is socketed in lower nest main body 2.

As shown in Figure 2, described movable part 5 is roughly in inverted "L" shaped, its rotating shaft 51 is positioned at the bottom of this movable part 5, preferred embodiment is, this rotating shaft 51 is formed in one with movable part 5, and both also can be respective independently parts certainly, now, this rotating shaft 51 both can be arranged on movable part 5, also can be arranged in lower nest main body 2.The left and right sides, bottom of described lower nest main body 2 lateral through aperture 21 offers groove 23, and this rotating shaft 51 is embedded in this groove 23, and the free end on described movable part 5 top can rotating shaft 51 rotate thus pass in and out described through hole 21 bottom it thus.This movable part 5 upper free ends is convexly equipped with interior extension block 52 towards the inner side of umbrella shaft 1, and the bottom surface of this interior extension block 52 is provided with slide guide face 53, and this slide guide face 53 can be inclined-plane or cambered surface etc., and its side towards umbrella shaft 1 is higher.

As shown in Figure 4, the upper inside wall of described outer sleeve 3, being provided with recess 31 with this corresponding position, movable part 5 position, is connected by the second slide guide face 32 between this recess 31 with its underpart inwall.

Under umbrella closing state as shown in Figure 3, described outer sleeve 3 is positioned at the bottom of its sliding stroke, and it is outer and enter the recess 31 of outer sleeve 3 upper inside wall that the upper free ends of described movable part 5 is pushed out umbrella shaft 1.Push away outer sleeve 3 now and be positioned at parachute-opening position to lower nest main body 2, as shown in Figure 4, then descend the lateral through aperture 21 of nest main body 2 relative with the parachute-opening locating hole 11 of umbrella shaft 1 sidewall, the upper free ends of movable part 5 is inwardly promoted to make extension block 52 in this movable part 5 the inner enter in the parachute-opening locating hole 11 of umbrella shaft 1 by the lateral through aperture 21 of lower nest main body 2 by the second slide guide face 32 of outer sleeve 3 inwall, lower nest main body 2 can be limited in parachute-opening position thus.Now as pulled down outer sleeve 3, when this outer sleeve 3 be displaced downwardly to its inwall recess 31 relative with the upper free ends position of movable part 5 time, the upper free ends of this movable part 5 loses thrust and the restriction of outer sleeve 3 inwall, under the effect of outer sleeve 3 lower pulling force, slide guide face bottom the interior extension block 52 of movable part 5 53 is inconsistent thus the upper free ends of movable part 5 can be made outwards to shift out and enter the recess 31 of outer sleeve 3 upper inside wall with parachute-opening locating hole 11, the position-limiting action of movable part 5 to lower nest main body 2 is removed, and now can continue drop-down outer sleeve 3 until close one's umbrella.

In order to more accurately and reliably shift lower nest main body 2 onto parachute-opening position, as shown in Figure 3 and Figure 4, the spacing preiection 12 under restriction, nest main body 2 moved can be provided with in the position be positioned at above described parachute-opening locating hole 11 on umbrella shaft 1 sidewall, instantly nest main body 2 move to when offseting with this spacing preiection 12, interior extension block 52 inside described movable part 5 is just in time corresponding with parachute-opening locating hole 11 position of umbrella shaft 1 sidewall and lower nest main body 2 is locked in parachute opener, very easy to use.

The above is only embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
