Description

Improved racket of badminton

The utility model is relevant with the racket that motion is used, and is meant a kind of racket of improvement especially.Press, the general system of traditional racket comes for the intercalation that encircles frame two opposite ends and footstalk upper end with a kind of T connector that is referred to as three links, in order to the two is linked together, this kind is configured in actual use and goes up unsatisfactory, because the intercalation end of this footstalk strike at the ball hard or use length after tend to break away from the through hole of this T connector, and make racket to use, and its another shortcoming then is this T connector and this ring frame, the junction of footstalk can form the rank portion of projection and cause and be coated with the difficulty of loading onto, this kind disappearance is that the racket of footstalk is obvious especially with the fiber reinforcement plastic for being the ring frame with the aluminium-alloy pipe.

Therefore, the main purpose of the utility model is promptly at the racket that a kind of improvement is provided, and its footstalk that the ring frame made with aluminium alloy and fiber reinforcement plastic are made is bonded together closely.

Another main purpose of the utility model is promptly at the racket that a kind of improvement is provided, and the joint of its ring frame and footstalk is very level and smooth, and the rank portion that does not have projection produces.

Edge is, for reaching aforementioned purpose, the racket of the utility model improvement includes a footstalk, one ring frame, and one throat link this footstalk and this ring frame, this footstalk system is made by fiber reinforcement plastic, this ring frame system is bent by aluminium-alloy pipe and forms, have relative two sides in order to converge with one of this footstalk end, it is characterized in that: this throat includes by binder couse in one of fiber reinforcement plastic institute moulding outer covering layer and, this outer covering layer system is attached at the surface of these ring frame two opposite side ends and this footstalk one end, it is T-shaped interiorly to link series of strata, and sky was inner among two sides of its level were filled in respectively and filled in these ring frame two opposite side ends, and its vertical end then is connected with one of this footstalk end, by this, make this ring stand and this footstalk this throat of mat to be bonded together closely.

The preferred embodiment of lifting a utility model now cooperates graphic being described as follows:

First figure is the stereogram of the utility model one preferred embodiment.

Second figure is the utility model one preferred embodiment, in the cutaway view of first Fig. 2-2 direction.

At first, see also first figure and second figure, the racket of the utility model one preferred embodiment has the ring frame 12 that an aluminium-alloy pipe is bent into and constitutes striking surface in order to wear netting twine 14, one footstalk 16 is the elongate bone made from a fiber reinforcement plastic, one throat 18 connects this ring frame 12 and this footstalk 16, one wooden handle 20 is fixed in the open end of this footstalk 16, and a taper upper shield 22 is socketed on the junction of this handle 20 and this footstalk 16.

This throat 18 is by an outer covering layer 24, binder couse 26 in one, two core bodys 28, and two stop block 30 constitute, this outer covering layer 24 is the surface that is attached at these ring frame 12 2 opposite side ends 121,122 and these footstalk 16 upper ends, should in binder couse 26 be T-shaped, two sides 261,262 of its level fills in respectively and are filled in empty inside among these ring frame 12 2 opposite ends 121,122,263 of its vertical end are held with one of this footstalk 16 and are connected; This core body 28 respectively, system is made by PU foaming material, be solid tubulose, one end 281 is to clog respectively in this within binder couse 26 2 horizontal sides 261,262,282 of the other ends extend outward and are attached on these ring frame 12 2 sides 121,122 inboard tube walls, this two stop block 30 is made by EVA, respectively caulked in this ring frame 12 2 opposite side ends 121,122 inner and with open end 282 butts of this core body 28 respectively; On making, it should interior binder couse 26 be to stack together by many to be preset with the carbon fiber of epoxy resin that this outer covering layer 24 reaches, before not being heating and curing as yet, promptly be coated on the meet of this ring frame 12 and this footstalk 16 and clog two opposite side ends 121 in this ring frame 12, in 122, respectively this core body 28 then be in as yet not the i.e. plug of foaming fill in each the horizontal side 261 of articulamentum 26 in this, in 262, by this, when being inserted, this throat 18 heated pressurization in the mould, this outer covering layer 24, should in binder couse 26, and respectively this core body 28 is plastic and should encircle frame 12 and this footstalk 16 combines closely.

In addition, in the preferred embodiment of one of the utility model, the thickness of this outer covering layer 24 system is decremented to this footstalk 16 and the identical mode of these ring frame 12 external diameters outward continuously with this meet certainly and is coated on respectively outside these ring frame 12 2 opposite side ends 121,122 and this footstalk 16 upper ends on the side surface, so the junction of this throat 18 and this ring frame 12 and this footstalk 16 does not have the rank portion generation of projection.
