Abstract

An aluminum bracket frame with an improved structure is provided. The main technical proposal of the aluminum bracket frame is as bellow: a body formed by bending an aluminum bracket frame on which thread holes for reticles to pass through are arranged, the reticles are sleeved with strip nails and made form a bracket surface with the reticles arranged crossly. The aluminum bracket frame is characterized in that a sunk part taking a sunk shape forms at the crossing positions of the reticles and having the two ends take the shape of a chamfer angle and shrink inwards. By making a sunk part taking a sunk shape and having the two ends take the shape of a chamfer angle and shrink inwards punched at the crossing positions of the reticles, the utility model strengthens the strength of the sunk part lest the thread hole parts at the crossing positions of the reticles do not distort or even rupture due to forced imposed on.

Description

Structure improved aluminium racket frame

Technical field

The utility model relates to the athletic sports appliance racket, refers to aluminium racket frame especially.

Background technology

See also shown in Figure 1, be to be general commercially available racket 1, it mainly is racquet frame 11 bending formings one body by aluminum, and be provided with the line hole 13 that can wear for netting twine 12 in this racquet frame 11, and on this line hole 13, be arranged with bar nail sheath 14, and make this netting twine 12 be vertical, traversed by is knitted and is formed a face, so construct, obviously be accomplished a racket 1, but because of requirement more and more light demand is arranged at present to racket weight, so the thickness of this racquet frame 11 presents more and more thin trend relatively, but the diameter of racket 1 is constant, relatively the demand to racquet frame 11 intensity is then more and more high for it, but as above-mentioned racquet frame 11, it is vertical in racket, the A of place, line hole of horizontal net wire intersection, it is because of being to be bending, so the spacing in its each line hole 13 is less, the big part of density, and it is because of being vertical, horizontal line 12 confluces, and make it stressedly be the place of whole racket 1 maximum, so, when tennis hits face, because of vertical, horizontal net wire 12 is simultaneously stressed, and when pullling mutually, the often easy deformation in the place, line hole that makes its netting twine 12 intersections, depression or fracture part.

Summary of the invention

Locate the technological deficiency of easy deformation, depression or fracture at the line hole of known racquet frame netting twine confluce, the utility model provides a kind of intensity of strengthening aluminium racket frame, to reduce the structure improved aluminium racket frame of racquet frame distortion or fracture.

For this reason, the technical solution of the utility model is: a kind of structure improved aluminium racket frame, it mainly is racquet frame bending forming one body in aluminum, and be provided with the line hole that can supply netting twine to wear in the body of this racquet frame, and on this line hole, be arranged with bar nail, and make the longitudinal and transverse face that is interwoven of this net, it is characterized in that forming the depressed part of a recessed shape, and the two ends of this depressed part are to be the chamfering shape also to contract toward at the longitudinal and transverse place of interweaving of netting twine.

This depressed part is the inner edge that is positioned at racquet frame, and its outer rim is to be a smooth-going cambered surface.

On racquet frame, form four depressed parts symmetrically respectively.

The outer rim shape of this depressed part can change with the shape of racquet frame.

Clearly, the utility model utilization is the depressed part of recessed shape in the place's punching press one of the line hole of the longitudinal and transverse netting twine intersection of racket, and the two ends of this depressed part are to be the chamfering shape also to contract toward in, and strengthened the intensity of this one, and then make the place, line hole of the longitudinal and transverse netting twine intersection of racket can not be out of shape or rupture because of stressed.

Fig. 1 is the schematic perspective view of common racket.

Fig. 2 is a floor map of the present utility model.

Fig. 3 is a part schematic perspective view of the present utility model.

Fig. 4 is the floor map of the utility model preferred embodiment.

The specific embodiment

See also Fig. 2 and shown in Figure 3, be to be the utility model plane and part generalized section thereof, it mainly is racquet frame 2 bending formings one body 21 by aluminum, and be provided with the line hole 23 that can supply netting twine 22 to wear in the body 21 of this racquet frame 2, and on this line hole 23, be arranged with bar nail sheath, and make this netting twine 22 vertical, traversed by is knitted and is formed a face 24, and it is vertical in this netting twine 22, the traversed by place of knitting forms the depressed part 25 of a recessed shape, and the two ends of this depressed part 25 are to be chamfering shape 251 also to contract toward in, and this depressed part 25 is the inner edges that place racquet frame 2, and the outer rim of racquet frame 2 then is a smooth-going cambered surface;

So, utilize the setting of the depressed part 25 that contracts toward in, its netting twine 22 longitudinal and transverse area and diameters that interweave the place are dwindled, and borrow and to be dashing of chamfering shape 251 and to establish, and change original conplane frame that is, and strengthen the intensity of this one, make square stance, it is stressed that it is concentrated, can be because of the depressed part setting that is the chamfering shape and contracts toward in, and the situation that can reduce frame distortion, depression or rupture.

Moreover, seeing also shown in Figure 4ly, is to be preferred embodiment of the present utility model, wherein, the netting twine 22 longitudinal and transverse places of interweaving on the body 21 of racquet frame 2 form the depressed part 25 of four recessed shapes symmetrically respectively, and the two ends of this depressed part 25 are to be chamfering shape 251 also to contract toward in.

Though the utility model is with simple structural change, can change the structure of common aluminium racket frame, and is strengthened the intensity of its frame, the enhancement with effect in fact is so propose patent application.

Claims (4)

1, a kind of structure improved aluminium racket frame, it mainly is racquet frame bending forming one body in aluminum, and be provided with the line hole that can supply netting twine to wear in the body of this racquet frame, and on this line hole, be arranged with bar nail, and make the longitudinal and transverse face that is interwoven of this net, it is characterized in that forming the depressed part of a recessed shape, and the two ends of this depressed part are to be the chamfering shape also to contract toward at the longitudinal and transverse place of interweaving of netting twine.

2, structure improved aluminium racket frame according to claim 1 it is characterized in that this depressed part is the inner edge that is positioned at racquet frame, and its outer rim is to be a smooth-going cambered surface.
