Abstract
The utility model relates to a string elasticity adjuster which is a device which is mainly used for adjusting the elasticity of the strings of a tennis racket, a badminton racket and other sports rackets. The string elasticity adjuster is provided with a connecting rod, a thrust screw rod, a base and a guide column. A string is hung and the thrust screw rod is screwed on the connecting rod, the thrust screw rod is rotated by a hand, the string is tightened and the elasticity is adjusted due to the action of a threaded mechanical wedge principle, so that the problem that the hitting effect is affected because the strings are loose is solved. The base and the guide column mainly play the roles of protecting, fixing and guiding. The string elasticity adjuster has very significant effect in enhancing the string elasticity, so that the service life of the strings is prolonged by two to three times compared with a string change method, and the string change cost is saved. In addition, the operation is convenient, so that general racket users can adjust.
Description
Affiliated technical field
The utility model relates to a kind of adjusting device of clapping string elastic force size, is mainly used in the adjustment that sports rackets such as tennis, shuttlecock are clapped string elastic force size.
Background technology
Wear in the sports of string racket in uses such as tennis, shuttlecocks, the elastic force of known bat string is to have configured according to user's situation when wearing string.In use, racket and ball clash into repeatedly mutually, and clapping string can be soft gradually, and elastic force also can descend thereupon, can have a strong impact on the effect of batting.Players take to change to clap the method for changing string and solve this problem.But it is many that this method is spent, and wasted bat string remaining service life, is not suitable for most of general sports persons.Understand and data-searching through market, do not find that other solve the soft method and apparatus of bat string.
The utility model content
In order to solve because of clapping the soft problem that influences balling effect of string, the utility model provides a kind of bat string elastic force adjuster, can soft bat string be tightened again.
The technical scheme that the utility model adopted is: a kind of device that is provided with connecting rod, thrust screw rod, pedestal, lead, connecting rod is provided with some internal threads that match with screw rod, be provided with some apertures of wearing the string of hanging up-racket, be provided with some sliding eyes that match with lead, lead is connected with pedestal.Hang some bat strings and the some screw rods of precession owing on connecting rod, can wear respectively, tighten when clapping string, rotate screw rod by hand, because the effect of the mechanics wedge principle of screw thread, produce the thrust of having amplified, promote connecting rod and endwisely slip, the slip of connecting rod spurs the extension of clapping string again, thereby string is clapped in tension, adjusts elastic force, reaches solution because of clapping the soft purpose that influences balling effect of string.Pedestal and lead mainly play protection, fixing and guide effect.
The utility model is fairly obvious for the effect of strengthen clapping string elastic force, has prolonged 2～3 times of service lifes of clapping string than the method for changing string, has saved the expense of changing string.And easy to operate, general racket user can both adjust voluntarily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the A-A sectional structural map of first embodiment, has shown the basic configuration and the make of connecting rod 1 of the present utility model, thrust screw rod 2, pedestal 3, lead 4.The hole slot of wearing the string of hanging up-racket that on the A-A section, has also shown connecting rod 1 and pedestal 3.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the A-A sectional structural map of second embodiment.
Fig. 4 is the vertical view of Fig. 3.
The specific embodiment
In first embodiment shown in Figure 1, it is a kind of device that is provided with connecting rod 1, thrust screw rod 2, pedestal 3, lead 4, connecting rod is provided with some internal threads that match with screw rod, be provided with some apertures of wearing the string of hanging up-racket, be provided with some sliding eyes that match with lead, lead is connected with pedestal.
The described connecting rod 1 of Fig. 1 is the rod member of a connection and power transmission.Rod member is provided with some internal threads and is connected with screw rod 2, is provided with some apertures of wearing the string of hanging up-racket and is connected with the bat string, and it is delivered to the thrust of screw rod 2 to it to clapping the pulling force of string.Also be provided with some sliding eyes that match with lead 4 on the rod member, the lead 4 that is connected with pedestal 3 pierces into sliding eye, and connecting rod can only be moved axially along lead.
The described thrust screw rod 2 of Fig. 1, screw rod epimere screw thread is spun on the connecting rod 1.The side that the hypomere thicker part divides is distributed with anti-slop serrations and digital calibration.The roundlet crown of screw rod lower end is on pedestal 3.When with anti-slop serrations rotary screw 2, screw rod 2 just promotes connecting rod 1 and endwisely slips.Digital calibration can be used for helping determining adjustment amount.
The described pedestal 3 of Fig. 1, the recessed crank slot below it are close on the frame outer of racket, and pedestal 3 is provided with some smooth apertures that match with the little round end of thrust screw rod, directly bear the roof pressure of screw rod 2 lower end round ends, and protection is clapped the string frame and is without prejudice.Pedestal 3 is provided with the fixing hole of some leads, simultaneously lead 4 is fixed on it.Pedestal 3 is provided with some apertures of clapping string that are used to pass, and the bat string passes the aperture of pedestal 3 and wears on the aperture that hangs over connecting rod 1 again, transmits connecting rod thus to clapping the pulling force of string.
The described lead 4 of Fig. 1, lead stage casing are the smooth axis of guides that matches with the connecting rod sliding eye, and the upper end is thicker spacing termination, and the lower end is the thicker fixedly termination that is fixed in the pedestal hole.It is fixed on the pedestal 3, is through in the hole of connecting rod 1, and connecting rod 1 can only be endwisely slipped along lead 4, and simultaneously, the effect of limiting rod 1 sliding scale is played in thicker termination, lead 4 tops.
In second embodiment shown in Figure 3, comprise connecting rod 1, thrust screw rod 2, pedestal 3, lead 4.
The upper end that thicker anti-slop serrations and digital calibration partly are made in screw rod on the described thrust screw rod 2 of Fig. 3, epimere is a screw thread, hypomere is thick slightly a bit can to prevent that screw rod from getting loose.
Described pedestal 3 of Fig. 3 and lead 4 can be made disjunctor.
