Description

The binding structure of umbrella stand

The utility model relates to a kind of binding structure of umbrella stand, particularly relates between a kind of main bone that constitutes with synthetic resin, fulcra certain affixedly strongly, and can improve the binding that umbrella stand links the umbrella stand of operating efficiency and construct.

The connection of umbrella stand in the past structure is that front end, cardinal extremity, the pars intermedia in bodies such as master metal bone, fulcra runs through axis hole; the shaft component of mat corn or pin etc. articulates; because of waiting the damage that causes bond sites because of corrosion with the made skeleton regular meeting of metal material; and; in order to make skeleton have elasticity and to alleviate the weight of umbrella stand body, so the material of employing synthetic resin such as the main bone of umbrella stand, fulcra forms at present.

But, if by the binding structure of main bone that synthetic resin constituted, fulcra etc. use aforementioned in the past the binding structure and the body of main bone, fulcra etc. is run through axis hole, can reduce the intensive properties of each skeleton, the frequent on-off action along with umbrella stand causes breakage easily.

Therefore, some umbrella stand utilization to be having the coupling member of reservation shape, just general resembles head, middle butterfly and bindings such as main bone, fulcra, middle rod, and is coated with affixed dose finishes and be fixedly connected between each skeleton body and connecting elements.Though can solving, this kind method of being fixedly connected on the skeleton body, runs through the not good problem of intensive properties that axis hole produces, but, because of this coupling member identical with the material of each skeleton, all be made by synthetic resin, and synthetic resin itself has smooth surface, when affixed with affixed dose, long-time use be exposed to make easily under the burning sun affixed dose rotten and cause affixed not exclusively, and, open and close for frequent repetitiousness and to use and the dipping of rainwater makes coupling member lack durability easily, the slip that causes coupling member breaks away from and causes the breakage of skeleton.In addition, with affixed dose of miscellaneous and labor intensive of injecting between each skeleton and coupling member of operation.

The purpose of this utility model makes between each skeleton body and coupling member certain affixedly strongly providing a kind of, and can improve the connection structure that umbrella stand links the umbrella stand of operating efficiency.

The binding structure of umbrella stand of the present utility model, comprise that a crimping is fixed in the hardware of the bar-shaped main bone pars intermedia that constitutes with synthetic resin or glass fibre or bar-shaped main bone, basic bone, middle excellent cardinal extremity, this hardware periphery union body that constitutes with synthetic resin that is coated and fixed in one piece.When being located at the pars intermedia of main bone, this hardware roughly is colyliform, and roughly is positioned on the union body center, and this union body is the support that tubular and central portion have two sheets.When being located at the cardinal extremity of bar-shaped main bone, fulcra, middle rod, fix with the hardware crimping of given shape in advance, make the union body made from synthetic resin coat this hardware of set more in one piece.

Be elaborated below by most preferred embodiment and accompanying drawing binding structure to umbrella stand of the present utility model, in the accompanying drawing:

Fig. 1 is the stereogram that hardware is fixed in the central portion of main bone in the utility model first preferred embodiment.

Fig. 2 is the combination stereogram of the utility model first preferred embodiment.

Fig. 3 is the combination top view of the utility model first preferred embodiment.

Fig. 4 is the stereogram that the cardinal extremity of main bone or fulcra is fixed in the hardware crimping in the utility model second preferred embodiment.

Fig. 5 is the combination stereogram of the utility model second preferred embodiment.

Fig. 6 is the combination stereogram of the utility model the 3rd preferred embodiment.

As Fig. 1 institute method, the binding of the utility model first preferred embodiment umbrella stand structure comprises the hardware 2 of a central portion that is located at the main bone 1 of the round bar shape base end part junction of fulcra (just with) colyliform of reeling, iron hoop etc. for example, this hardware 2 can directly form in main bone 1 body, utilize stamping machine that this hardware 2 is carried out the crimping set again, make hardware 2 firmly fix on the main bone 1 and can not slide.Shown in Fig. 2,3, this hardware 2 is outer to coat one of set with the integrally formed union body 3 of synthetic resin, this hardware 2 roughly is positioned on these union body 3 centers, this binding basis 3 is roughly tubular and central portion has two sheet supports 31,32, this two sheets support 31,32 is exactly the middle butterfly that is commonly called as, its top respectively is equipped with hole 33, and the middle part of two sheet supports 31,32 forms a groove 35 that is lower than union body 3 outer surfaces slightly.Two sheet supports 31,32 are articulated on the main bone 1 fulcra movably by this.

As shown in Figure 4, be the utility model second preferred embodiment, this binding structure comprise the hardware 2 that forms the crimp type terminal shape on the base end part that is plugged on round bar shape master bone, basic bone 4 ', utilize again stamping machine etc. to this hardware 2 ' rearward end (annulus) carry out the crimping set, make on the base end part of this hardware 2 ' firmly be bonded to fulcra 4 and can not slide.As shown in Figure 5, union body 5 that constitutes with synthetic resin of this hardware 2 ' coat in one piece outward set, in this hardware 2 ' this union body 5 of ground, position, this union body 5 is tubular and leading section to have and is tongue-shaped support 51, the front portion of this support 51 is equipped with hole, support 51 is articulated on the nest main bone movably whereby, or fulcra 4 are articulated on middle nest or the middle butterfly movably.

As shown in Figure 6, be the utility model the 3rd preferred embodiment, the hardware 2 that this binding structure comprises on the base end part that is wound on round bar shape master bone 1 and can directly form in main bone 1 body "; " front end forms and resembles head this hardware 2, rearward end is utilized stamping machine to carry out the crimping set and is formed annulus, through the crimping operation of stamping machine, make hardware 2 and " firmly be bonded on the base end part of main bone 1 and can not slide.This hardware 2 " outer coating set is with the integrally formed union body 7 of synthetic resin, this hardware 2 " is arranged in union body 7, should; Connector 7 roughly is tubular and its leading section has the support 71 that resembles head, and what promptly be commonly called as resembles head.The top of this support 71 is equipped with hole 72, and support 71 makes main bone 1 articulate freely with the round main rib activity whereby.

Hardware of the present utility model is not particularly limited, and can form as the crimp type terminal shape or resembles head, if when hardware is the crimp type terminal shape, as second embodiment, pairing union body then forms tubular and its leading section has tongue-shaped support.If hardware is when resembling head, as the 3rd embodiment, pairing union body forms the head that resembles that is commonly called as.

The utility model is fixed on each the skeleton body that is made of synthetic resin by the hardware of classes such as iron, can avoid synthetic resin to slide to each other, and bear the frequent application of force that opens and closes of parachute kit, and be not subjected to the influence of rainwater dipping, and, this hardware is synthesized the union body coating that resin constitutes, and does not undermine umbrella cloth so can not be exposed to extraneous rust.

In addition, the utility model can save and inject numerous and diverse operation process of affixed dose, increase work efficiency, and the intensity of each the skeleton body that does not influence synthetic resin and constituted.

No matter binding of the present utility model structure is hand, self-action or folding to constitute the parachute kit of main bone, fulcra with synthetic resin all applicable.
