Description
Technical field
The utility model relates to a kind of adjustable tensioner of racket net string.
Background technology
At present, in tennis racket or this motion of wearing string racket of 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 pulling force of net string and the effect of impact of ball, net string is elongated gradually, causes net string to become slack, and tension force declines, serious impact the effect of batting.Common solution is the net string again more renewing, although do so feasiblely, has wasted the remaining life of net string, for most of sports persons, has increased motion cost simultaneously.
In order to address the above problem, the utility model patent that name is called " a kind of racket net string tension adjuster " is disclosed in CN202892829U, this adjuster comprises pedestal, connecting rod and bolt, described pedestal is arranged on racket moon eyebrow beam outside, described connecting rod is positioned at pedestal top, one end of described screw rod withstands on pedestal through connecting rod, is provided with net string corresponding and that penetrate for net string hole on pedestal and connecting rod.The adjuster of structure can play the effect of adjusting at any time racket net string tension although it is so, but, net string is through pedestal and connecting rod, in threading and use procedure, net string will and month eyebrow beam, pedestal or/and produce friction between connecting rod, net string is easily worn until break, and has so just shortened the service life of net string.
Utility model content
The purpose of this utility model is just to provide and a kind ofly can effectively prevents the racket that net string is worn.
The purpose of this utility model is to realize by such technical scheme, a kind of adjustable tensioner of racket net string, comprise the frame with net string, in the moon of described frame, the arranged outside of eyebrow beam has pedestal and the connecting rod connecting by net string, described net string is connected with connecting rod with pedestal through a month eyebrow beam, it is characterized in that: on connecting rod, establish boss part, on connecting rod, be threaded in addition and screw rod that both sides arrange.
Wherein, described boss part comprises cambered surface boss or is provided with cambered surface boss and the wire bushing pipe of wire casing; A cambered surface boss and two wire bushing pipes are the inverted U-shaped and ganoid threading body that is linked as; A boss part is independent threading body or is connected in one by several inverted U-shaped threading bodies.
Wherein, described connecting rod comprises collar aperture and screwed hole, and screwed hole is pressed triangle or rectangular arranged on the both sides of long center line; The circumferential profile of connecting rod can be the shaped form adapting with collar aperture or screwed hole, can be also linear.
In the utility model, on described connecting rod, the screw rod lower end corresponding with screwed hole is smooth cambered surface, and upper end is four directions or six square toes that are applicable to spanner.
Further describe, pedestal lower surface is and corresponding linear or the arc line shaped of moon eyebrow beam;
Or described pedestal is integrated setting with a month eyebrow beam.
When using the technical program, only need balanced slightly each screw rod on connecting rod that turns, under the thrust of screw rod, connecting rod elongates net string, and the tension force of net string is just recovered and is adjustable; Owing to having adopted the included relevant technologies of boss part, make net string obtain good protection.
Owing to having adopted technique scheme, it not only can effectively prevent the friction between moon eyebrow beam, net string and pedestal, net string and the connecting rod of net string and racket, has extended the service life of net string, has reduced use cost; And structure is good, stability is high, and impact resistance is strong, and damping property is good, and appearance looks elegant is lightweight, is conducive to the advantages such as industrially scalable manufacture.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:

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 improvement on the present embodiment essence spirit or substitute, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of adjustable tensioner of racket net string, comprise the frame 2 with net string 1, the moon of described frame 2 eyebrow beam 3 arranged outside have pedestal 4 and the connecting rod 5 connecting by net string 1, described net string 1 is connected with connecting rod 5 with pedestal 4 through a month eyebrow beam 3, and connecting rod 5 is provided with boss part 7, is threaded in addition and the screw rod 6 of both sides setting on connecting rod 5.Due to described technology, can not only adjust easily the size of the tension force of net string, also avoided the wearing and tearing of tensioner to net string.
Embodiment 2: as shown in Figure 3,4, described boss part 7 comprises cambered surface boss 9 or is provided with cambered surface boss 9 and the wire bushing pipe 11 of wire casing 10; A cambered surface boss 9 and two wire bushing pipes 11 are the inverted U-shaped and ganoid threading body that is linked as; A boss part 7 is independent threading body or is connected in one by several inverted U-shaped threading bodies.
Because connecting rod 5 must be made by the higher material of working strength, for example use aluminum alloy materials, therefore easily damage net string.And boss part 7 can be used softer material to make, plastics for example, it is easy to be again processed into smooth inverted U-shaped, so, by the cambered surface boss 9 that has wire casing of boss part 7 and smooth wire bushing pipe 8, can effectively prevent the friction between net string 1 and connecting rod 5, prevent the wearing and tearing of net string 1.
Embodiment 3: as shown in Figure 2, comprise collar aperture 12 and screwed hole 13 on described connecting rod 5; Screwed hole 13 is pressed triangle or rectangular arranged on the both sides of long center line; The circumferential profile of connecting rod 5 can be the shaped form adapting with collar aperture 12 or screwed hole 13, can be also linear.Collar aperture 10, for inserting the wire bushing pipe 8 of boss part 7, is avoided connecting rod 5 direct friction of net string and hard material.Screwed hole 13 is for being screwed into screw rod 6 tension net strings, and screwed hole 13 press triangle or rectangular arranged on the both sides of long center line, has strengthened the stability of connecting rod 5 bracing wires, has also improved the impact resistance of anti-tennis shock.Between described collar aperture 10 and collar aperture 10 and screwed hole 13, by being connected the curve of outer surface, connect, doing like this one is to make the strength ratio of connecting rod 5 more balanced, and weight is lighter, and the strength when impacting ball consumes less, the 2nd, and make outward appearance more attractive in appearance.
Embodiment 4, and as shown in Figure 7, screw rod 6 lower ends corresponding with screwed hole 13 on described connecting rod 5 are smooth cambered surface, and while using to reduce screw rod 6, the frictional force of pedestal 4 is pressed on top.Upper end is four directions or six square toes that are applicable to spanner, conveniently turns screw rod.
Embodiment 5: as shown in Figure 5,6, described pedestal 4 lower surfaces are and corresponding linear or the arc line shaped of moon eyebrow beam 3; Pedestal also can be made of one with moon eyebrow beam.Pedestal can be used plastic production, has both been conducive to install be fitted on moon eyebrow beam 3, has played the effect padding with damping, can carry again the powerful top power of screw rod.
