The utility model has the advantages that: the bending strength of the long bone of the solid D-shaped column body is high, and the stability is good; the long bone is installed on the rib main part in a matching manner, the side plane of the long bone is in contact with the umbrella cloth, so that the contact area of the long bone and the umbrella cloth is increased, and the long bone is not easy to slide.

Description

Umbrella

Technical Field

The utility model belongs to the technical field of the parachute kit, especially, relate to an umbrella.

Background

The umbrella is a common tool for shading sun or avoiding rain, plays an important role in the life of people, but the traditional umbrella has a common problem that long bones can slightly deform after being used for a period of time, and can slightly bend due to the memory fatigue of the long bones when being folded, so that the long bones can seriously deform in the past, the service life of the umbrella is shortened, and a bulge is formed in the middle of the umbrella, so that the integral attractiveness of the umbrella is influenced. Therefore, improvements are needed.

Disclosure of Invention

The utility model aims at providing an umbrella aiming at the defects existing in the prior art.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides an umbrella, includes rib main part, umbrella cloth and a plurality of group around the skeleton that the rib main part set up, the skeleton includes short bone and long bone, install well dish on the long bone, short bone articulates on well dish, umbrella cloth and rib main part and long bone are supporting to be connected, long bone is solid D type cylinder, and its cross sectional shape is solid D type, the supporting side plane of installing on the rib main part and long bone of long bone with the umbrella cloth contact.

The long bones are made of FRP.

The connecting end of the middle dish and the short bone hinged with the middle dish is wrapped with an anti-hair clamping protective sleeve.

The hair clamping preventing jacket is a cloth jacket or a soft rubber jacket.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is:

1. the bending strength of the long bone of the solid D-shaped column body is high, and the stability is good;

2. the long bone is installed on the rib main part in a matching manner, the side plane of the long bone is in contact with the umbrella cloth, so that the contact area of the long bone and the umbrella cloth is increased, and the long bone is not easy to slide.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.

Examples, see fig. 1-3: an umbrella comprises an umbrella rib main body 1, umbrella cloth and a plurality of groups of frameworks 2 arranged around the umbrella rib main body 1, wherein the umbrella rib main body 1 comprises a middle rod 3, an upper nest 4, a middle nest 5 and a handle 6 which are arranged on the middle rod 3 in a matched mode, the frameworks 2 comprise short bones 7 and long bones 8, a middle dish 9 is arranged on the long bones 8, one ends of the short bones 7 are hinged to the middle dish 9, one ends of the long bones 8 are connected with a joint 10, the long bones 8 are connected with the upper nest 4 through the joint 10, and the other ends of the short bones 7 are connected to the middle nest 5; the umbrella cloth is connected with the umbrella rib main body 1 and the long ribs 8 in a matching way.

The long bone 8 is a solid D-shaped cylinder, the cross section of the long bone is of a solid D shape, the long bone 8 is mounted on the umbrella rib main body 1 in a matched mode, and the side plane 11 of the long bone 8 is in contact with the umbrella cloth. The long bone 8 of solid D type cylinder bending strength is high, and stability is good, long bone 8 the side plane 11 with umbrella cloth contact for the area of contact of long bone 8 and umbrella cloth increases, makes long bone 8 be difficult for sliding.

The long bone 8 is made of FRP, and the FRP is fiber reinforced composite plastic. The FRP has high tensile strength, almost no plastic deformation is generated, and stress and strain rise in linear elasticity when being pulled until the FRP is brittle failure; the FRP has good corrosion resistance and fatigue resistance, so the service life of the FRP is long; the FRP has high specific strength, namely, the FRP is light and high in strength, so that the self weight of the structure can be reduced by adopting the FRP material, the construction is convenient, and the weight of the FRP material is generally 20 percent of that of steel. Therefore, the long bone 8 made of FRP has the advantages of good strength, difficult deformation, long service life and light weight.

The connecting end of the middle disc 9 and the short bone 7 hinged with the middle disc 9 is wrapped with an anti-hair-pinching protective sleeve 12, and the anti-hair-pinching protective sleeve 12 is a cloth protective sleeve or a soft rubber protective sleeve. When the umbrella is used, because the height relation of the umbrella is held by hands, the hair of people can easily contact the framework 2, the joint of the middle dish 9 and the middle dish 9 of the common framework 2 and the short rib 7 is exposed, so that the hair can be easily clamped or clamped by the joint of the middle dish 9 and the short rib 7, the umbrella holder can feel painful, and the hair clamping prevention sheath 12 can prevent the hair from being clamped or clamped by the joint of the middle dish 9 and the short rib 7.
