Abstract

The utility model relates to a circular-skeleton frame for an umbrella, which comprises a covering head, a skeleton body and a ball tail. The utility model is characterized in that the covering head, the skeleton body and the ball tail form an integral type member through integral injection moulding or multi-step combined injection moulding, and the integral type covering head, skeleton body and the ball tail member can be make of injection moulding plastics. The utility model changes the original circular-skeleton frame used for an umbrella and assembled and accomplished by three parts to an integral frame formed by plastics through one-step or multi-step combined pressing, and the utility model has the advantages of easy processing, firmness without easily loosening and manpower and raw material saving and is suitable for various umbrella frames.

Description

A kind of Umbrella frame

The utility model relates to a kind of umbrella goods, particularly a kind of Umbrella frame

Existing umbrella, for example folding umbrella, can two folding or three folding straight-bar umbrellas, comprise a large amount of skeletons in its part, this skeleton contacts with umbrella cover, the structure of skeleton is split, this circle skeleton comprises packet header, diaphysis, pearl tail.Packet header and pearl tail are made of metal, and are installed on two ends of diaphysis respectively, and this diaphysis is a long pole, can be manufactured by metal or plastics.This structure weak point is that processing is bothersome, need manufacture three parts separately.With packet header, the pearl tail is installed on diaphysis two ends respectively then, has formed round bone skeleton, owing to be fabricated skeleton, it is firm inadequately to produce assembling, the phenomenon that easily gets loose.In addition, manufacture three parts respectively and no matter be raw material or, need use the sheet stamping blanking,, take equipment, mould, manually all bigger, cause the cost rising through operations such as punching, bendings manually all than waste, particularly packet header part.

The purpose of this utility model provides a kind of Umbrella frame, and it can solve the deficiency of above-mentioned prior art, promptly has processing simply, and goods are firm to be difficult for loosening the damage, and saves workman and raw material.

The purpose of this utility model realizes by following technical scheme, and a kind of Umbrella frame comprises packet header, diaphysis, pearl tail, it is characterized in that: described packet header, diaphysis, pearl tail are that integral molded plastic or gradation merge the integrated support structure that injection moulding forms.But described monoblock type packet header, diaphysis, pearl tail are made by the injection-moulded plastic injection moulding.The utility model adopts the Umbrella frame with original split to change whole skeleton into, to change the plastics identical or different into by packet header, the pearl tail that metal is manufactured with the diaphysis material, available mould of plastics once or gradation merge compression moulding, form whole skeleton, processing is simple.But employed plastics are the raw material of injection moulding, for example ABS, PP or PE etc.Owing to be whole skeleton, need not assembling, make the firm damage that can not get loose of goods.Adopt same raw material in three parts, need not to adopt this metalwork of sheet metal punching press, save artificial and raw material.

In sum, the utility model is all used plastic pressing forming because employing is improved to three parts with original umbrella of being finished by three parts assemblings with circle bone skeleton, form whole skeleton, have and process simple, the firm damage that is difficult for getting loose of goods, and save artificial and raw material, cause productivity ratio to improve, the goods cost reduces.The utility model is suitable for various Umbrella frames.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the structural representation of existing Umbrella frame.As shown in Figure 1, existing Umbrella frame comprises packet header 1, diaphysis 2, pearl tail 3, packet header 1 is by sheet metal punching press, bending and be held on an end of diaphysis 2, pearl tail 3 is manufactured by metal, centre bore 6 cover on it is pressed in the other end of diaphysis 2, has pilot hole 4 on packet header 1, is used for the utility model is contained on the umbrella being connected with other part, on pearl tail 3, have pilot hole 5, be used for threading itself and umbrella cover 9 (referring to Fig. 5,6) are fixed together.

Figure 2 shows that the utility model monoblock type Umbrella frame.As shown in Figure 2, the packet header 1 of skeleton, diaphysis 2, pearl tail 3 are whole, are formed by the plastics compacting, and the three fuses.

Figure 3 shows that the form in the another kind of packet header of the utility model monoblock type Umbrella frame, Figure 4 shows that L among Fig. 3 is to view.Fig. 5,6 shows the position of the utility model monoblock type Umbrella frame in umbrella.As shown in the figure, the utility model monoblock type Umbrella frame A links to each other with inner frame B.Fig. 5 does not strut situation for this umbrella, and 4 places, hole in packet header between each skeleton A, B are hinged, situation when Fig. 6 struts for umbrella, and along pushing away on the umbrella handle 7, then support 10 is propped up interior round bone skeleton B, circle bone skeleton A, and umbrella cover 9 is propped up with slide block 8.

Claims

1, a kind of Umbrella frame comprises packet header, diaphysis, pearl tail, it is characterized in that: described packet header, diaphysis, pearl tail are the integrated support structure that integral molded plastic forms.

2, a kind of Umbrella frame according to claim 1 is characterized in that: but the packet header of described integral body, diaphysis, pearl tail are made by injection-moulded plastic.
