Description
Technical field
The invention belongs to tennis equipment technical field, relate to the tennis racket that a kind of center of gravity is adjustable.
Background technology
Tennis is the sports of a grace and fierceness, usually carries out between two singles sportsmen or two pairs of doubles combinations.Sportsman impacts hollow rubber ball across net tennis racket on tennis court.Wherein tennis racket is the indispensable equipment of tennis, tennis racket by racket head, clap larynx, handle forms, also need in use to coordinate the accessories such as tennis line, shock absorber to use.Because the use habit of different users is all different, the position of centre of gravity for tennis racket requires different, and the impact effect of tennis racket on tennis that center of gravity is different simultaneously also has important impact.Such as, laborsaving before head tip-tap net, bottom line is required great effort, nose heave knit a net before effort, but bottom line is laborsaving.
As Chinese utility model patent application (application number: the tennis racket 201120399243.9) disclosing a kind of weight-adjustable, the outer oval perisporium of the head frame of this tennis racket adopts groove structure, the groove structure of this frame is also supporting is outward provided with wire bushing, correspondingly on the wall that groove is relative with wire bushing be provided with buckle structure, wherein buckle structure is made up of button column body and block button hole, and button column body is uniformly distributed along groove side face; This tennis racket also comprises some weight stacks in addition, and on the described weight stack button column body be enclosed within a frame groove facing each other, this tennis racket needs when center-of-gravity regulating manually dismantled by wire bushing and regulate weight stack, uses and comparatively bothers.
Summary of the invention
The present invention is directed to existing technology and there are the problems referred to above, propose the tennis racket that a kind of center of gravity is adjustable, the tennis racket that this center of gravity is adjustable can center-of-gravity regulating, and convenient to operation.
Object of the present invention realizes by following technical proposal: the tennis racket that a kind of center of gravity is adjustable, comprise oval framework and handle, described handle is connected in one end of framework, it is characterized in that, described framework inner circumferential offers guide channel, slide in described guide channel and be provided with the magnetic mass of tool, described guide channel madial wall is all fixed with the main silicon steel sheet of tubular in framework end positions, guide channel madial wall is all fixed with the auxiliary silicon steel sheet of tubular at framework two side position, the lateral wall of described main silicon steel sheet and auxiliary silicon steel sheet is all wound with coil, power supply is fixed with in described handle, above-mentioned coil is all connected with power supply, described handle is also provided with the switch that can control above-mentioned coil electricity or power-off.
Framework and handle integral structure, and framework ovalize, two main silicon steel sheets lay respectively at the two ends up and down of oval frame long axis of body, and two auxiliary silicon steel sheets lay respectively at the left and right sides of oval framework minor axis, mass has certain weight and magnetic, can change the center of gravity of framework entirety when it moves to diverse location.Controlled the coil power on/off on different main silicon steel sheets or auxiliary silicon steel sheet by gauge tap when needing center-of-gravity regulating, and main silicon steel sheet or auxiliary silicon steel sheet during coil electricity, can be made to produce magnetic force, namely suction or repulsion are produced to neighbouring mass, thus mass is moved in guide channel, the magnetic force also produced by the coil electricity at this place after mass moves into place fixes mass, convenient to operation, but also the position change can effectively avoiding mass when swinging the bat because inertia produces and the racket center of gravity disorder caused.
In the tennis racket that above-mentioned center of gravity is adjustable, on described guide channel madial wall, circumference offers four annular mounting groove, these four mounting groove circumferences are uniformly distributed, above-mentioned main silicon steel sheet and auxiliary silicon steel sheet are connected in mounting groove respectively, and described guide channel madial wall flushes with the madial wall of main silicon steel sheet and auxiliary silicon steel sheet.Mounting groove is used for setting-in coil, main silicon steel sheet and auxiliary silicon steel sheet, namely plays fixation, makes guide channel madial wall flush with the madial wall of main silicon steel sheet and auxiliary silicon steel sheet simultaneously, avoid mass to move and occur catching phenomenon.
In the tennis racket that above-mentioned center of gravity is adjustable, the medial surface of described guide channel is shiny surface.Shiny surface is to reduce frictional force when mass moves.
In the tennis racket that above-mentioned center of gravity is adjustable, described mass is spherical shape, and the lateral wall of mass and guide channel madial wall lean.Mass and guide channel lean, and block position after moving into place of can ensuring the quality of products is unique, there will not be and rocks.
In the tennis racket that above-mentioned center of gravity is adjustable, described mass is spherical shape, and the surrounding of mass is enclosed with magnetic fluid.Magnetic fluid, also known as magnetic liquid or flowing molten iron body, is a kind of liquid with the larger intensity of magnetization, and by nanometer, ferromagnetic or Ferrimagnetic particle is suspended in fluidity carrier (normally organic solvent or water) for it, the soliquid made.There is the material more than a kind of state of matter, therefore can change its phase with magnetic field.Utilize magnetic fluid as the lubricating fluid of mass, mass can be made to be in the encirclement of lubricating fluid all the time, sportsman can the position of quality of regulation block rapidly at any time as required, changes the position of centre of gravity of tennis racket.
In the tennis racket that above-mentioned center of gravity is adjustable, the transparent shape of described framework.The framework of transparence can be known when mass moves and sees its position, handled easily, and adjusting position is accurate.
In the tennis racket that above-mentioned center of gravity is adjustable, described switch has four, and these four switches are connected with four coils respectively.Namely different switches controls different coils respectively, and each coil is operation separately separately, does not interfere with each other, by four switches.
In the tennis racket that above-mentioned center of gravity is adjustable, the end axis of described handle is to offering installing hole, and above-mentioned electric power connecting is fixed in installing hole, the end of described handle is hinged with end cap, described end cap sidewalls has limited post, and when end cap covers, limited post end is pressed on the end of power supply.Electric power connecting is in installing hole and undertaken compressing fixing by limited post, can extract power supply and carry out changing or charging when opening end cap, easy to use.
Compared with prior art, the tennis racket that this center of gravity is adjustable has the following advantages:
1, owing to being controlled the coil power on/off on different main silicon steel sheets or auxiliary silicon steel sheet by gauge tap, its magnetic force produced produces suction or repulsion to neighbouring mass, thus mass is moved in guide channel, the magnetic force also produced by the coil electricity at this place after mass moves into place fixes mass, convenient to operation.
2, due to the transparent shape of framework, can know when mass moves and see its position, handled easily, adjusting position is accurate.
3, because power supply is detachably installed, power supply can be extracted when opening end cap and carry out changing or charging, easy to use, power supply can certainly be extracted after center of gravity regulates, not affect the weight of tennis racket.
