Abstract

The invention provides a badminton racket with adjustable attack strength and adjustable middle tube elastic hardness. An axial sliding element is arranged in a middle tube elastic point of the badminton racket, the sliding element is of a hard hollow tube shape, a cavity is formed, between the sliding element and the top end of a middle tube of the badminton racket, of the middle tube, and a sliding block with a certain weight is arranged in the cavity and can slide in the cavity. Due to the fact that the middle tube elastic point is moved forward, the length of a force arm is shortened, ball hitting response speed is increased, force is increased, and a player needs to have large explosive force; the situation is opposite if the elastic point is moved backward, and the player obtains the best ball hitting effect suitable for the explosive force by adjusting the position of the elastic point. When the player hits a badminton ball and waves the badminton racket, the sliding block in the middle tube slides to the head portion of the badminton racket to reach the top end of the middle tube or the top end of the sliding element, so that the gravity center of the badminton racket is changed, the weight of the head portion of the badminton racket is increased, ball hitting force is increased, and people can buy fewer badminton rackets and save cost.

Description

Attack dynamics, middle tubular elastic hardness adjustable type racket

Technical field

The present invention relates to physical culture enure equipment technical field, is exactly a kind of attack dynamics, middle tubular elastic hardness adjustable type racket.

Background technology

Prior art mesoptile racket be by the framework that is installed with line, in pipe, three major parts of handle form.The racket that middle tubular elastic is good is subject to liking of player, but because the do not coexist explosive force size of square stance of player's consitution is also different, for same the different player of racket, can feel in racket pipe or soft or firmly can not obtain best balling effect.According to player's different choice, also need to increase attack dynamics simultaneously.

Prior art solution is that to produce the different racket of tubular elastic in Multiple Type selective.Nonetheless because of tubular elastic in every racket of the same model of technical reason, also can not accomplish just the samely, player can only just can know whether in actual use and be applicable to oneself.And the variation of player's fitness playing skill also can cause original racket to be no longer applicable to oneself.

Summary of the invention

The object of the invention is to design a kind of attack dynamics, middle tubular elastic hardness adjustable type racket, the racket of tubular elastic in regulating to a certain extent by regulating middle tube of battledore DISCRETE ELASTIC SUPPORTS position and change king-rod hardness, and hit for increasing

Ball dynamics, has designed the weightening finish parts that slide.

Part can endwisely slip at middle tube of battledore DISCRETE ELASTIC SUPPORTS place built-in, described sliding part is hard hollow tubular, in sliding part and racket described in middle pipe, manage between top one section of cavity is set, a slide block with constant weight is set in this cavity, it can slide in described cavity.

Or, at middle tube of battledore DISCRETE ELASTIC SUPPORTS place built-in, have the certain length part that can endwisely slip, described sliding part is that hard hollow tubular is coaxial with middle pipe, and described sliding part upper end arranges limiting section, one slide block with constant weight is set in its hollow bulb, and it can slide in described hollow bulb.

There is a through hole at described slide block center.Described slide block can have the slip of damping in its sliding cavity.Described sliding part is connected to the adjustment part of handle portion by lower end link, described adjustment part utilizes the mode of threaded adjustment that described sliding part is moved axially in middle pipe by connecting rod.On badminton racket handle, have and can endwisely slip at a middle tube of battledore DISCRETE ELASTIC SUPPORTS place built-in part coincideing with middle tube cavity of the corresponding indicating device in adjustment part and cue mark.By this sliding part, moving axially in middle pipe forces middle tubular elastic point to move forward and backward within the specific limits that (parts that the movement of this sliding part is converted into axial moving force by handle built-in by revolving force complete, this adjustment part can be mechanical device, can be also electric device.

Advantage of the present invention is: preferred mechanical type of drive, and in handle bottom, to have cue mark, these parts that are connected with adjustment part can be also other form or in other position.Because of in tubular elastic point reach arm of force contraction in length make to bat that reaction speed is accelerated and strength strengthens, and need player to have larger explosive force, after DISCRETE ELASTIC SUPPORTS, move on the contrary, player puts by adjustable elastic the best balling effect that position obtains applicable own explosive force.When racket is brandished in player's batting, the slide block in middle pipe slides to racket head, reaches middle pipe top or sliding part top, thereby change racket center of gravity, has increased the weight of racket head weight, has increased striking force.Thereby and can reduce purchase racket and economize on the use of funds.

Accompanying drawing explanation

Fig. 1 is racket longitudinal sectional view.

Fig. 2 is another embodiment schematic diagram.

Fig. 3 embodiment is collet front view.

In figure: 1 knob, 2 collets, 3 are converted into revolving force in axial moving force parts, 4 handles, 5 connecting rods, 6 and manage in sliding part, 7 in pipe, 8 slide blocks.

The specific embodiment

Below in conjunction with drawings and Examples, the invention will be further described.

Embodiment 1

Part can endwisely slip at middle tube of battledore 7 DISCRETE ELASTIC SUPPORTS places built-in, described sliding part is hard hollow tubular, in sliding part 6 and racket described in middle pipe 7, manage between top one section of cavity is set, a slide block 8 with constant weight is set in this cavity, it can slide in described cavity.

Embodiment 2

Described in above-mentioned two embodiment, there is a through hole at slide block center.Described slide block can have the slip of damping in its sliding cavity.Described sliding part is connected to the adjustment part of handle portion by lower end link, described adjustment part utilizes the mode of threaded adjustment that described sliding part is moved axially in middle pipe by connecting rod.On badminton racket handle, have and can endwisely slip at a middle tube of battledore DISCRETE ELASTIC SUPPORTS place built-in part coincideing with middle tube cavity of the corresponding indicating device in adjustment part and cue mark.By this sliding part, moving axially in middle pipe forces middle tubular elastic point to move forward and backward within the specific limits that (parts that the movement of this sliding part is converted into axial moving force by handle built-in by revolving force complete, this adjustment part can be mechanical device, also can be electric device, this programme preferred mechanical type of drive, and in handle bottom, have cue mark, these parts that are connected with adjustment part can be also other form or in other position).Because of in tubular elastic point reach arm of force contraction in length make to bat that reaction speed is accelerated and strength strengthens, and need player to have larger explosive force, after DISCRETE ELASTIC SUPPORTS, move on the contrary, player puts by adjustable elastic the best balling effect that position obtains applicable own explosive force.When racket is brandished in player's batting, the slide block in middle pipe slides to racket head, reaches middle pipe top or sliding part top, thereby change racket center of gravity, has increased the weight of racket head weight, has increased striking force.

As Figure 1-3, by the knob 1 on rotary bottom support 2, make the parts 3 that revolving force is converted into axial moving force by managing interior sliding part 6 interior the moving axially of middle pipe 7, with tubular elastic point position in changing in connecting rod 5 drives.When brandishing racket, slide block also slides in its container cavity, to change center of gravity, increases the striking force of swinging the bat.
