Abstract

The utility model relates to a racket structure, mainly comprising a racket frame which is in a ring shape and a grab handle, wherein, one side of the racket frame is connected with the grab handle and a plurality of thread holes are arranged inward from outside. Screen wire is interwoven into a stroke wire side through the thread holes. The racket structure is characterized in that a plurality of lugs which are not connected with each other and are separated with a preset distance are convexly formed in the middle part of the outer side surface of the racket frame, the thread holes are arranged on both ends of the lugs, and the screen wire passes through along the surfaces of the lugs. The racket structure has the advantages that the weight of the racket can be lightened efficiently, and the strength of the racket frame is not affected.

Description

A kind of structure of racket

The utility model belongs to a kind of improvement of sports equipment racket, particularly a kind of racket structure with wire side.

Raising along with people's living standard, tennis, shuttlecock, motion such as squash is more and more universal, constantly move back and forth at square stance, hand exercise burden problem is become the key factor of kinematic dexterity and ability of controlling the ball to the weight that makes racket, and overweight racket also can cause athletic injury, usually the structure of this class racket connects lever 2 by head frame 1 as shown in Figure 1, and on framework 1, have a plurality of through wires holes 3, be through at wherein tension with netting twine 4 intersections and form the batting wire side, the square stance ball is passed to framework to the impulsive force of wire side by netting twine 4, therefore, framework must have certain thickness and intensity, can not damage with the impulsive force that can bear square stance, and traditional structure can't alleviate the weight of racket, make the sportsman pay bigger amount of exercise, hand is very easily tingle and influence kinematic dexterity and ability of controlling the ball, also may cause athletic injury.

The purpose of this utility model is exactly in order to solve the problem of known racket commonly used, designs a kind of novel racket structure, it can weight reduction not be influenced again be subjected to force intensity.

Formation of the present utility model comprises a ringwise frame and a lever, one side of frame and lever joins and by having a plurality of through wires holes in the lateral, netting twine is woven into the batting wire side through through wires hole, the middle body that it is characterized in that the frame lateral surface convexes to form several projections not continuous each other and preset distance of being separated by, through wires hole is opened the two ends in projection, and netting twine passes through along lug surface.

Fig. 1 is a tennis racket structural representation commonly used;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the part sectional schematic diagram of the novel structure of this reality.

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

An one ringwise frame 10 and a lever 20, one side and the lever 20 of frame 10 join, the middle body of frame 10 lateral surfaces convexes to form several projections 12, each projection 12 does not link to each other and the predetermined distance of being separated by each other, frame 10 radially runs through several through wires holes 14 of formation to the inside from its lateral surface, and through wires hole 14 is opened respectively in the two ends of each projection 12, so that two lines 30 are by through wires hole 14, and be woven into the batting wire side that a tool is set tension force by penetrating another adjacent through wires hole in the inboard footpath of frame 10 latitudes along projection 12 surfaces, the outer rim at projection 12 two ends forms slick and sly extrados 122 respectively, to reduce the stress concentration phenomenon that each projection 12 may be formed by netting twine 30 pressure what two ends.

According to above-mentioned structure, the utility model has the advantages that: make netting twine 30 longer with the contact length frame commonly used of frame 10 by each projection 12 of what, to increase the contact area of netting twine 30 and frame 10, (P represents pressure by P=F/A, F represents active force, A represents active area) principle, the pressure that frame 10 is born is commonly used lower, to improve its service life; Simultaneously, strengthen its intensity by what frame 10 of the present utility model by each projection 12, make the material thickness of frame 10 to reduce relatively, cooperate the interval of each projection 12 to be provided with again and more can reduce racket weight effectively, uses comfortable, ball-handling is stable and the possibility of attenuating athletic injury.

Claims (2)

1. the structure of a racket, mainly comprise a ringwise frame and a lever, one side of frame and lever joins and by having a plurality of through wires holes in the lateral, netting twine is woven into the batting wire side through through wires hole, the middle body that it is characterized in that the frame lateral surface convexes to form several projections not continuous each other and preset distance of being separated by, through wires hole is opened the two ends in projection, and netting twine passes through along lug surface.

2. the structure of racket according to claim 1 is characterized in that the projection two ends outer surface of described frame outer rim forms slick and sly extrados respectively.
