Abstract

The utility model relates to an umbrella stick structure, which is mainly composed of a main umbrella stick, a branch umbrella stick and a hinging seat and is characterized in that a coating position and the hinging seat are respectively formed by injecting rubber in a groove of the U-shaped umbrella stick at the hinging seat where the main umbrella stick and the branch umbrella stick are connected; the hinging seat is in an integral forming with the main umbrella stick and is used for riveting and fixing one end of the branch umbrella stick; the main umbrella stick is accommodated by a coating body; a plurality of ring bodies are formed by injecting rubber in the groove of the main umbrella stick on both sides of the hinging seat and on the circumferential edges of the main umbrella stick and are in an integral forming with the main umbrella stick. The structure enhances the rigidity and the solidity of the whole umbrella stick, prevents the structure from bending and breaking under great wind resistance, extends the service life of the umbrella.

Description

Umbrella frame structure

The utility model relates to the structure of umbrella, refers to that especially a kind of injecting glue that gives at umbrella main umbrella skeleton and the umbrella frame place of interconnecting forms a Umbrella frame structure that clads body and hinged seat.

Umbrella structure commonly used at present, (referring to Fig. 1) is seamed on the main umbrella skeleton 101 that is radial arrangement by umbrella cover 100, and form a hinged seat 102 in the centre position of main umbrella skeleton 101, (referring to Fig. 2,3,4) gives rivet for umbrella frame 103 1 end and fastens, the other end then wears and is fixed on the slip ring 104, slip ring 104 is socketed in umbrella handle 105 and slides up and down, and makes umbrella frame 103 and main umbrella skeleton 101 connecting parts form angle and produces that umbrella cover 100 opens or the action of condensation.The structure of the hinged seat 102 that the main umbrella skeleton 101 of umbrella commonly used as shown in Figure 3 is connected with a umbrella frame 103, wherein insert and put the flange brace 106 that central authorities float in the groove that main umbrella skeleton 101 takes the shape of the letter U, an end that props up umbrella frame 103 stretches into riveted and fixed in the brace 106, and can rotate along main umbrella skeleton 101.Fig. 4 is the structure of another kind of hinged seat, and wherein the brace 107 that inserts and puts in main umbrella skeleton 101 grooves is that an end forms flange 108, and an end rivet clasp of a umbrella frame 103 is on flange 108.

More than the structure of two kinds of umbrella frames, when wind-force was big slightly, windage stress all concentrated on hinged seat 102 or the flange 108, caused main umbrella skeleton 101 in this position bending, the phenomenon of fracture (referring to Fig. 5) reduces the life-span of umbrella.

The purpose of this utility model is: provide a kind of solid, durable, long service life is difficult for bending at the position of hinged seat, the problem of fracture, and structure is more reasonable, assembles more simple, suitable rain in early spring umbrella rib structure.

The purpose of this utility model is to realize like this, a kind of Umbrella frame structure is mainly by main umbrella skeleton 200, prop up umbrella frame 201, hinged seat 202 is formed, it is characterized in that: at hinged seat 202 positions that main umbrella skeleton 200 is connected with a umbrella frame 201, in the groove of umbrella frame that takes the shape of the letter U, give injecting glue respectively and penetrate formation one cladding body 204 and hinged seat 202, this hinged seat 202 is integrally formed with main umbrella skeleton 200, and for umbrella frame 201 1 an end riveted and fixed, main umbrella skeleton 200 204 of cladded bodies are ccontaining, in hinged seat 202 both sides main umbrella skeletons 200 grooves, and give injecting glue at main umbrella skeleton 200 peripheries and penetrate several ring bodies 205, this ring bodies 205 is one-body molded with main umbrella skeleton 200.

Advantage of the present utility model is: hinged seat and main umbrella skeleton injecting glue are one-body molded, made things convenient for a umbrella frame mount last, simplified assembling, the cladded body of main umbrella skeleton ccontaining and also in the groove of main umbrella skeleton and the periphery injecting glue of main umbrella skeleton several ring bodies are arranged, so increased the rigidity of main umbrella skeleton, be enough to resist the size of wind-force, increased the crooked structural strength of umbrella frame opposing, make umbrella more solid, more reasonable structure, the life-span is longer.

Concrete structure of the present utility model further specifies by following examples and accompanying drawing thereof.

Referring to Fig. 6, a kind of Umbrella frame structure is mainly by main umbrella skeleton 200, prop up umbrella frame 201, hinged seat 202 is formed, it is characterized in that: at hinged seat 202 positions that main umbrella skeleton 200 is connected with a umbrella frame 201, in the groove of umbrella frame that takes the shape of the letter U, give injecting glue respectively and penetrate formation one cladding body 204 and hinged seat 202, this hinged seat 202 is integrally formed with main umbrella skeleton 200, and for umbrella frame 201 1 an end riveted and fixed, main umbrella skeleton 200 204 of cladded bodies are ccontaining, in hinged seat 202 both sides main umbrella skeletons 200 grooves, and give injecting glue at main umbrella skeleton 200 peripheries and penetrate several ring bodies 205, this ring bodies 205 is one-body molded with main umbrella skeleton 200.Wherein hinged seat 202 is the structures that form in injecting glue ejaculation process with main umbrella skeleton 200 one, one end that therefore can conveniently prop up umbrella frame 201 penetrates rivet and buckles 203 mounts at this, saved umbrella element commonly used, another separate connection piece element punching press must be made up the required time in umbrella frame during assembling, formed cladding body 204 can be with main umbrella skeleton 200 in the umbrella frame groove for injecting glue in addition, hinged seat 202 positions are restrainted puts, produce fixed strength, the firm solidity that injecting glue penetrates in the umbrella frame groove and can increase umbrella frame at the plastic material that the umbrella frame periphery forms a ring bodies 205, resisted crooked strength load, ring bodies 205 can be put with umbrella frame outer rim bundle and is combined as a whole penetrating plastic material in groove, increases the structural strength of Umbrella frame opposing bending.

Referring to Fig. 7 is side diagrammatic sketch of the present utility model, analyse and observe the position among the figure and be the position of the hinged seat 202 that main umbrella skeleton 200 is connected with a umbrella frame 201, the main umbrella skeleton 200(at this position is simultaneously referring to Fig. 8,9) during front and cross section are cutd open and are shown, can know that the cladding body 204 of finding out the injecting glue injection molding puts fixed situation with main umbrella skeleton 200 bundles, there is the depressed part 206 that forms punching press at cladded body 204 ccontaining positions in the side of main umbrella skeleton 200, this depressed part is uneven, rough, it is tightr that cladding body 204 that favourable injecting glue ejaculation forms and main umbrella skeleton 200 are bonded with each other, adding that ring bodies 205 that injecting glue penetrates clad to restraint to put with main umbrella skeleton 200 outer rim positions connects as one, more increased the strength that plastic material is connected with main umbrella skeleton 200 surfaces, so improved the firm solidity of whole umbrella rib structure, referring to Figure 10, the utlity model has the big wind resistance of opposing and can not bend, fracture is so prolonged the service life of whole umbrella.
