Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

The utility model discloses lie in through the locking hole and the switch hole of separating catch, locking ball, switch ball, locking spring, separating lock groove, switch groove and the installation ball on the nest base constitute the locking mechanical system of parachute kit jointly, lock the parachute kit state when launching for the parachute kit and provide reliable structure.

In particular, referring to fig. 1-4, various views of a handle umbrella nest structure with locking structures according to the present invention are disclosed.

The handle umbrella nest comprises a nest base 5, a middle rod 1 penetrating through the nest base 5, an unlocking ring 7 surrounding the outer side of the upper part of the nest base, a locking ball 8 and a switch ball 9 which are fixed on the nest base in an embedded mode, and a locking spring 10 for pressing the switch ball;

wherein the nest base 5 surrounds the middle rod 1, a plurality of locking balls 8 and at least one switch ball 9 are respectively fixed on the nest base 5 in a nesting way along the direction of the middle rod,

Specifically, referring to fig. 2, the locking ball 8 is fixed on the locking hole 12 of the nest base 5 in a nesting manner, and the switch ball 9 is fixed on the switch hole 13 of the nest base 5 in a nesting manner. In the drawings of the present invention, the locking ball is on the top and the switching ball is on the bottom. However, the present invention is not limited to this, and the ball may be locked down, and the switch ball may be up, as long as both are arranged in the extending direction of the middle rod.

Between the switch ball 9 and the central rod there is a ring of locking springs 10, said locking springs 10 being able to force the switch ball 9 towards the nest base 5;

see fig. 3, fig. 4. The unlocking ring is provided with a switch groove 16 and an unlocking groove 15 at positions corresponding to the switch ball 9 and the locking ball 8 respectively; wherein the switch groove 16 includes recesses at both sides and a protrusion in the middle; one concave part of the unlocking groove and the switch groove corresponds to the same straight line;

at the locking level of the king-rod there is a king-rod annular groove 11.

Therefore, when the locking ball 8 is positioned in the unlocking groove 15 and the switch ball is positioned in one concave part of the switch grooves in the same straight line, the locking ball is positioned in the unlocking groove 15, does not protrude out of the nest base 5, and cannot be clamped with any position of the middle rod, so that the opening or the folding of the umbrella cannot be limited.

When the unlocking ring is pulled to the locking height, for example, corresponding to the annular groove 11 of the central rod, the unlocking ring 7 is rotated by a certain angle, so that the switch ball moves from one concave part of the switch groove to the other concave part through the middle protrusion part and is fixed in the other concave part by the outward elastic force provided by the locking spring 10, and a hand feeling prompt and an audible prompt of click are provided in place. Because the switch ball and the locking ball are embedded in the nest base 5, the rotation of the switch ball drives the locking ball 8 to move similarly, so that the switch ball is pushed out from the unlocking groove 15, the locking ball 8 is clamped in the annular groove 11 of the middle rod under the limitation of the inner cylindrical surface and the embedding position of the unlocking sleeve 7, such as the locking hole 12, the locking function is realized, and the umbrella cannot move up and down. In addition, the distance between the locking spring 10 and the outer cylindrical surface of the upper middle rod is limited, so that the inward movement distance of the switch ball 9 is limited, the switch ball 9 cannot be completely immersed into the nest base 5, the switch ball 9 is always matched with the switch groove 16, and the unlocking ring 7 is prevented from falling off in the using process.

Similarly, the rotating unlocking ring 7 is turned in reverse by a certain angle, so that the switch ball moves from the other recess to the one recess through the middle protrusion and is fixed in the other recess by the outward elastic force provided by the locking spring 10, and a click-feeling prompt and an audible prompt are provided in place. The rotation of the switch ball will drive the locking ball 8 to move the same, so as to move to the position corresponding to the unlocking groove 15, and the locking ball is embedded in the unlocking groove 15 and not limited by the middle rod annular groove 11, so as to unlock, and the umbrella can move up and down.

Therefore, the width between the two concave parts of the switch slot is equivalent to the rotating width of the unlocking device, when the locking ball is positioned in the unlocking slot, the whole umbrella nest is in an unlocking state, and when the locking ball is pushed out of the unlocking slot and clamped in the annular groove 11 of the middle rod, the whole umbrella nest is in a locking state.

Further, a locking hole 12 and a switch hole 13 are arranged on the nest base 5;

the locking hole 12 is used for installing and limiting a locking ball;

the switch hole 13 is used for mounting and defining a switch ball.

The lower part of the nest base is provided with a plurality of annular grips 14, which provide enough space for hands to hold and are convenient to use.

The annular grip 14 may be a semicircular annular indentation, which provides a slip-resistant feature and a good hand-feel.

The locking ball and the switch ball are common finished products of quenched steel balls, so that the processing and manufacturing flow and the assembly process are simplified, and the structural strength is improved.

The upper part of the nest base is provided with an umbrella nest cover 3, and the periphery of the umbrella nest cover 3 is regularly connected with a plurality of flat head supporting ribs 2 through connecting balls 4 in a clamping way.

Thus, each of the flat-head support bones 2 can rotate about the connecting ball 4.

There are also plastic bushings 6 on the inside of the nest base 5 where it contacts the middle bar, said plastic bushings 6 having a plurality of places.

The plastic bushing can prevent the surface abrasion caused by long-term sliding friction between the nest base and the upper middle rod from influencing normal use and product appearance; meanwhile, the gap between the handle umbrella nest structure and the middle rod during up-and-down movement can be reduced, the reliability of the structure is ensured, and meanwhile, the texture of the product is improved.

Therefore, the utility model has the advantages of as follows:

The above description is for the purpose of describing the invention in more detail with reference to specific preferred embodiments, and it is not to be construed that the embodiments of the invention are limited thereto, and it will be apparent to those skilled in the art that the invention can be embodied in many different forms without departing from the spirit and scope of the invention as defined by the appended claims.
