Abstract
The utility model discloses a tension adjuster for a racket net string. The tension adjuster comprises a base seat (1), a connecting rod (2) and a screw rod (3). The base seat (1) is arranged at the outer side of a racket crescent beam (4). The connecting rod (2) is located above the base seat (1). One end of the screw rod (3) penetrates through the connecting rod (2) and abuts on the base seat (1). Net string holes (5) which are corresponding to each other and used for enabling the net string to penetrate are formed both in the base seat (1) and in the connecting rod (2). The tension adjuster for the racket net string has the advantages of being simple in structure and convenient to manufacture and install. The net string tension of the racket can be rapidly adjusted by the adoption of the tension adjuster, and therefore service life of net threads is prolonged, cost for changing the string is saved, and controlling of hitting a ball of a user is largely improved through precise adjustment of the tension adjuster for the racket net string.
Description
Technical field
The utility model relates to a kind of racket net string tension adjuster, and is particularly a kind of for the racket net string tension adjuster on the tennis racket.
Background technology
At present, in this motion of wearing the string racket of tennis racket or racket, the tension force of netting twine directly affects the elastic force of racket, and the known tension force of wearing string racket net string is just accurately set by wearing tumtum when wearing string.Under the effect of impact of the pulling force of net string and ball, the net string is elongated gradually, causes the net string to become slack, and tension force descends, and has seriously influenced the effect of batting.Common solution is the net string that again more renews, although do so feasiblely, has wasted the remaining life of net string, for most of sports persons, has increased the motion cost simultaneously.On market, do not find at present other solutions.
The utility model content
The purpose of this utility model just provides a kind of racket net string tension adjuster that can adjust at any time the racket net string tension.
The purpose of this utility model is to realize by such technical scheme, a kind of racket net string tension adjuster, it comprises pedestal, connecting rod and screw rod, described pedestal is arranged on the racket moon eyebrow beam outside, described connecting rod is positioned at the pedestal top, one end of described screw rod passes connecting rod and withstands on the pedestal, is provided with corresponding and is used for the net string hole that the net string penetrates at pedestal and connecting rod.
For the stability of screw rod, end face corresponding with connecting rod on described pedestal is provided with groove, and an end of described screw rod withstands in the groove.
Wherein, described pedestal be direct rod shape or be bent upwards shaft-like or reclinate shaft-like.
In order to reduce member, strengthen stability, described pedestal can be integrated setting with moon eyebrow beam.
For the friction that reduces the net string with lose, make that to wear the string path round and smooth, in the upper surface of connecting rod wired TV station is set, described line platform is between two net string holes.
In the utility model, be provided with screwed hole at described connecting rod, described screw rod passes screwed hole, and described screwed hole is 2～6.
When described screwed hole was 2, screwed hole was arranged before and after being the diagonal arrangement or being positioned on the center line.
When described screwed hole was 3, screwed hole was triangularly arranged.
When described screwed hole is 4 or 6, the rectangular arrangement of screwed hole.
For the stability of pedestal, between pedestal and month eyebrow beam, be provided with pad.
For the ease of adjusting, above-mentioned screw rod one end is square or hexagon, and the other end is semicircle, and this end withstands in the groove.
Owing to having adopted technique scheme, the utlity model has advantage simple in structure, that manufacturing is easy for installation, adopt it to adjust the net string tension of racket fast, so not only prolonged the service life of netting twine, but also save the expense of changing string, by the accurate adjustment of this adjuster to the net string, so that the user is improved greatly to the controlled of batting.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: shown in Fig. 1,2,3,4,5, a kind of racket net string tension adjuster, it is characterized in that: it comprises pedestal 1, connecting rod 2 and screw rod 3, described pedestal 1 is arranged on racket moon eyebrow beam 4 outsides, described connecting rod 2 is positioned at pedestal 1 top, one end of described screw rod 3 passes connecting rod 2 and withstands on the pedestal 1, is provided with corresponding and is used for the net string hole 5 that the net string penetrates at pedestal 1 and connecting rod 2.
In the utility model, the net string passes successively to wear back from adjacent net string hole 5 behind the net string hole 5 on pedestal 1, the connecting rod 2 again and enters into net and clap, when the net string is soft, and only need to being screwed into a bit screw rod 3 symmetrical equilibriums, just can strain the net string, reach the purpose of recovering or adjusting net bat tension force in good time.
In order to keep the stable of screw rod 3, end face corresponding with connecting rod 2 on described pedestal 1 is provided with groove 6, and an end of described screw rod 3 withstands in the groove 6, and simultaneously, groove 6 not only can positioning screw 3, and the top pressure surface that can also increase screw rod 3 is long-pending, alleviates pressure.
In the utility model, pedestal 1 is direct rod shape, certainly, also can according to the actual requirements pedestal 1 be made be bent upwards shaft-like or reclinate shaft-like.
In the utility model, pedestal 1 is integrated setting with a month eyebrow beam 4, does like this so that pedestal 1 is more reliable and more stable, can also improve its weight capacity simultaneously.
In order to reduce the friction of net string on pull bar, prevent fracture, also in order to increase the service life, in the upper surface of connecting rod 2 wired TV station 7 is set simultaneously, described line platform 7 is between two net string holes 5.
In the utility model, be provided with screwed hole 8 at connecting rod 2, described screw rod 3 passes screwed hole 8, described screwed hole 8 is 2～6, its screw rod passes screwed hole 8, and what the present embodiment adopted is 3 screwed holes 8, and is triangularly arranged, do so not only can so that stressed evenly, but also manufacturing cost is lower.
Certainly, the number of screwed hole can be set according to actual needs also, such as: screwed hole 8 is 2, and be diagonal arrange or be positioned on the center line before and after arrange or screwed hole 8 is 4 or 6, rectangular arrangement.
For so that pedestal and month eyebrow beam can be stable fit together, between pedestal 1 and month eyebrow beam 4, be provided with pad 9, adopt the pad with the gap-fill between pedestal and the moon eyebrow beam, reduced the huge pulling force of the net string that adjuster brings owing to the gap.
The person adjusts pulling force by screw rod for handled easily, and screw rod 3 one ends that adopt in the utility model are square or hexagon, and the other end is semicircle, and this end withstands in the groove 6.
