Abstract

The utility model discloses a locating structure of the umbrella shaft, the locating structure is implemented with an inner tube and an outer tube of the umbrella shaft; the upper side wall of the outer tuber is provided with a recess; a slide-way is formed in the axis direction of the inner tube wall which is at the corresponding position of the recess, and the outer tube side wall in the direction vertical to the recess is provided with a locating hole; wherein, the lower-part of the inner tube is provided with a sleeve inside, a convex pole is arranged along the radial direction of the sleeve inner wall; a through hole is arranged on the sleeve wall facing the convex pole, the through hole is communicated with the hole on the inner tube wall, one end of a spring is hitched onto the convex pole, the other end thereof connects the convex grain through the sleeve and the inner tube through-hole; a plate is arranged at the center of the convex grain to avoid the convex grain fully protruding beyond the locating hole of the outer tube. The sleeve is fixed at the lower part of the inner tube with the fixing component, and the fixing component can be blocked below the recess of the outer tube. As the convex grain is fixed by the sleeve in the radial direction, and the sleeve is fixed by the fixing component, the sleeve can not disengage under the outside force, the convex grain can not dislocate; so, the structure makes the outspread location of the inner and outer tubes of the shaft more positive and stable.

Description

Rod positioning structure in the umbrella

Technical field

The utility model is about a kind of middle bar structure of many folding umbrellas, is meant rod positioning structure in a kind of umbrella especially.

Background technology

Multi-bended parachute kit, be to rely on location structure to realize launching to locate between each pole spare of middle rod, shown in Fig. 1, Fig. 2 A, Fig. 2 B, this location structure, how being built-in with " V " type arculae 3 ' in the below of interior pipe 1 ', a side of arculae 3 ' laterally is provided with a protruding grain 31 ', and this protruding grain 31 ' is stretched by the through hole on the inner tubal wall and placed outside the interior pipe 1 ', when middle rod launched, this protruding grain 31 ' can be stretched the locating hole 21 ' that places outer tube 2 ' and go up the realization location.When closing one's umbrella, the protruding grain 31 ' of locating hole 21 ' extruding of outer tube 2 ' utilizes the elasticity of arculae 3 ' again, and protruding grain 31 ' can bounce back in outer tube 2 ', and rod folds in the realization.This " V " type arculae 3 ' be fully utilize the tension force of its opening and cooperate be implemented in cooperating of through hole on the protruding grain 31 ' of side direction and the inner tubal wall in fixing in the pipe 1 ', when if parachute kit is beaten by external force, this arculae 3 ' can break away from the precalculated position easily, the protruding grain 31 ' phenomenon that can't locate occurs.Excellent inner and outer pipes 1 ' in having again, connection after launching between 2 ', be that pit 22 ' is beaten on the top that relies on outer tube 2 ', interior pipe 1 ' corresponding this pit 22 ' is formed with chute 12 ', bottom and chute 12 ' original position at interior pipe 1 ' form the pit 22 ' below of a boss 13 ' in order to be fastened on outer tube 2 ', pipe 1 ' can not deviate from from outer tube 2 ' in making, because this boss 13 ' is to form by extruding with chute 12 ' original position, thereby boss 13 ' can form an inclined-plane with chute 12 ', then meet strength and use the greater, when managing 1 ' in rod is firmly extracted in the expansion, easily interior pipe 1 ' is extracted from outer tube 2 '.

The utility model content

Main purpose of the present utility model provide a kind of make in the umbrella between each pole spare of rod the location really, rod positioning structure in the not eely umbrella of setting element.

Secondary objective of the present utility model provides a kind of more firm location structure of each pole spare connection of rod in the umbrella that makes.

For achieving the above object, solution of the present utility model is: the location structure of rod in the umbrella, be to cooperate the inner and outer pipes of rod in the umbrella to implement, set pit on the sidewall on outer tube top, corresponding this pit axially is formed with chute at inner tubal wall, is provided with locating hole on the sidewall of outer tube and pit vertical direction; Wherein: a built-in sleeve pipe in the bottom of interior pipe, internal surface of sleeve pipe radially extends a projection, projection over against casing wall be provided with a through hole, this through hole communicates with through hole on the inner tubal wall, one spring, one end is nested with on projection, the through hole that the other end sees through sleeve pipe and interior pipe connects a protruding grain, and the rear portion of protruding grain is provided with and prevents that it from convexedly stretching in the retaining platform outside the outer tube locating hole fully; The bottom of pipe in this sleeve pipe is fixed on by a retaining element, this retaining element can be fastened on the pit below of outer tube simultaneously.

The front portion of described protruding grain forms the circular arc head, and the middle part forms the retaining platform, and its rear end forms protruding pin and is used to connect spring.

Described retaining element can be a pin, in the two ends of pin convexedly stretch in outside the pipe and can with the pit blocking mutually of outer tube.

Described retaining element can be two T-shape stators, and it is fixing on inner pipe with sleeve pipe to see through inner tubal wall, the part in its protruding placing outside the pipe and the pit blocking mutually of outer tube.

Described sleeve pipe is the plastic cement pipe, so that form the projection of inwall.

After adopting such scheme, because the location structure of rod in the utility model umbrella, be to be fixed with the spring that radially is provided with by a sleeve pipe, spring connects the elasticity positioning function that protruding grain is realized inner and outer pipes, and sleeve pipe is the bottom of pipe in being fixed in by retaining element, it can not broken away from by external force, and then protruding of the location that is provided with on it also can not misplace, and so the expansion location of the inner and outer pipes of rod is certain more, stable in the order.

In addition, with sleeve pipe fixing retaining element on inner pipe be convexedly stretch in outside the pipe, form step surface with inner tubal wall, more firm during again with the pit blocking of outer tube, be so limited, when managing in chance user with stronger dynamics firmly extracts it is broken away from from outer tube, the inner and outer pipes of rod connects more firm in making.
