Abstract

The utility model relates to a shock-absorption structure for rackets, which can reduce the shock of a grab handle when a tennis ball is hit. A tennis elbow is caused easily by an existing racket. An amount of containing space is dug inside the grab handle of the racket axially. A plurality of rod bodies (52) connected with elastic bodies (54) at the end are convexly formed on the inner side surface of a back sleeve barrel axially. At least one side of each elastic body (54) is contacted with the inner wall of the grab handle (30). The racket can absorb the received shock when the tennis is hit. The incidence rate of sport injuries can be reduced to a great extent.

Description

A kind of racket shock sucking structure

The utility model relates to racket, particularly a kind of racket shock sucking structure of subduing the vibrations of square stance lever.

In the motion that relates to the racket class, the athletic injury of normal generation is " tennis elbow ", especially with tennis for.Tracing it to its cause mainly is not to use the person to brandish the racket square stance, the relative motion between racket wire side and flyball and form go out vibrations through racquet frame, lever and reach user's elbow, elbow causes because of bearing this impact endurance test shock for a long time.Be the influence of low vibrations of begging to surrender to elbow, many with the attached racket wire side that is hung on of the bar with shock-absorbing effect, or follow closely with the bar that vibration absorptive material is made and to wear netting twine, these all only are the means of taking stopgap measures, general damping effect is quite limited, and the way of the attached linked network face of employing shock-absorbing bar can cause the opposite effects of racket wire side area reduction.

The skeleton of tradition racket is one of the forming mostly, especially lever partly fixedly integrates with the frame main shaft, therefore, when wire side adopts additional shock-absorbing bar as mentioned above, though can absorb the vibrations of few part, and the vibrations of exhausted major part still can be passed to lever by the frame main shaft, and accept by the hand of sportsman's grasping lever, often cause sportsman's arm that tingle sensation is arranged, wherein serious with elbow especially, get off for a long time and just caused the athletic injury of " tennis elbow ".

Main purpose of the present utility model is to provide a kind of racket shock sucking structure, and the racket of Sheng Chaning can be subdued the vibrations that are passed to sportsman's hand through racket main shaft, lever significantly in view of the above, to reduce the injured incidence of elbow.

The utility model is realized by following technology.It comprises that mainly one can open the head frame of establishing for wire side, the one side extension of head frame connects establishes a lever, a terminal nested back sleeve of lever, it is characterized in that the lever inner shaft forms a predetermined number accommodation space to digging to establish, back sleeve medial surface axial projection forms the body of rod that equates with the accommodation space number, the end of each body of rod connects respectively establishes an elastomer, and the inwall of at least one side of each elastomer and lever is inconsistent, to absorb the vibrations of batting.

With drawings and Examples the technical solution of the utility model is described further below.

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is a handle portion cutaway view of the present utility model.

Fig. 3 is the body of rod structural representation of tool positioning plate.

Fig. 4 is a back tube-in-tube structure schematic diagram.

Fig. 1 shows the utility model has one can supply wire side (10) to open the head frame of establishing (20) as prior art; one side joint of head frame (20) is established a lever (30); the terminal nested back sleeve (40) of lever (30); and twine a soft protective layer (34) in the periphery of this lever (30); be beneficial to hand and grip, the utility model is that the indoor design at lever (30) has two accommodation spaces (32).

It is the cylindrical shell of reservation shape that Fig. 2 shows back sleeve (40).Plug is established one and is located base plate (50) between the end of inside and the lever (30) of back sleeve (40), one side shaft of positioning plate (50) is convexly equipped with two bodies of rod (52) to extension, the body of rod (52) inserts respectively in separately the accommodation space (32), the end of the body of rod (52) connects respectively establishes an elastomer (54), all side book offices of elastomer (54) are inconsistent with the sidewall of its accommodation space (32) separately respectively, to absorb, to cut down the suffered vibrations of lever (30).

Fig. 3 shows radially digging of the body of rod (52) and is provided with several sunken holes (56) in order to alleviating the weight of the body of rod (52), and uses dispersion, intercepts the transmission of the body of rod (52) to vibrations, helps lever (30) to subdue vibrations.In the specific implementation, also positioning plate (50) directly can be integrated with back sleeve (40) or the body of rod (52) is made with the material with shock-absorbing characteristic, can form various embodiment.

Advantage of the present utility model is when brandishing the racket square stance, flyball reaches this head frame (10) by wire side vibrations are passed to lever (30) by head frame (10), in transmittance process, vibrations are each elastomer (54) and absorb, and unabsorbed vibrations are subdued through the effect that each body of rod (52) utilizes its beat to restrain again, are finally prevented by back sleeve (40).Confirm through test of many times, the actual square stance of swinging the bat, the vibrations that hand bore have been almost equal to zero, and sportsman's hand can not produce tingle sensation again, has the effect that reduces the athletic injury incidence significantly really.

Claims

1. racket shock sucking structure, comprise that mainly one can open the head frame of establishing (20) for wire side, the one side extension of head frame (20) connects establishes a lever (30), a terminal nested back sleeve (40) of lever (30), it is characterized in that lever (30) inner shaft forms a predetermined number accommodation space to digging to establish, back sleeve (40) medial surface axial projection forms the body of rod (52) that equates with the accommodation space number, the end of each body of rod (52) connects respectively establishes an elastomer (54), and the inwall of at least one side of elastomer (54) and lever (30) is inconsistent.

2. a kind of racket shock sucking structure according to claim 1 it is characterized in that an end radial dilatation of the body of rod (52) forms a location base plate (50), and positioning plate (50) is positioned at just between lever (30) end and back sleeve (40) medial surface.
