Description

Net

Technical field

The utility model is related to sports equipments, and in particular to a kind of net.

Background technology

Net campaign is gradually worldwide promoted as a kind of emerging movement, and the movement is mainly in traditional net It is developed on the basis of ball movement.Net is for traditional tennis, and mainly place reduces, and net height reduces, Racket size reduces, and reduces the antagonism of traditional tennis, equally also reduces the technical difficulty of traditional tennis.Thus net phase For traditional tennis, human body is required greatly to reduce, becomes a kind of outdoor activity project suitable for people of all ages.

And existing net campaign ball used and traditional tennis difference are smaller, internal structure and material are almost It is identical.Since traditional tennis elasticity and weight are larger, due to inertia after player's batting, tennis flying speed is very fast, flying distance Farther out, this so that opponent is difficult accurately to fight back, and receives to player and brings the difficulty of bigger, is hardly formed the air exercise of more bouts, So that the nature of leisure of net campaign is had a greatly reduced quality.

Invention content

The net that the utility model provides, it is intended to solve that existing net-fault velocity of shuttle flight is too fast, what player was difficult to receive Problem.

A kind of net, wherein the net ball body main body is foam sphere, and body interior center is hollow Cavity, the main body are equipped with the air hole for penetrating through the cavity and body surfaces.

The net, wherein the ball for resisting construction deformation is equipped in the cavity, the ball is PE materials The hollow sphere of matter, the ball surface are equipped with air hole.

The net, wherein the ball outer surface is complex as a whole with the cavity inner surface using ultrasonic wave.

The net, wherein the body outer surface is equipped with wear-resisting clad.

The net, wherein the clad is fabric.

The utility model provides a kind of net, relatively traditional by setting ball body main body to hollow foam Tennis not only reduces ball body weight, while ball body diameter can do more, and is increased in net flight course with this The air drag received, to reduce net-fault velocity of shuttle flight；Body interior setting body interior ball can prevent from batting When the excessive deformation of main body caused by foam globules rupture, increase net service life；Air hole is arranged in main body and ball surface, So that air can not compress in cavity when ball figure becomes, from the elasticity for reducing ball body, reduce the initial velocity of impact, simultaneously It also reduces net and hits the vibrations that racket generates so that the net has splendid incabloc function；Body surfaces coat Wear-resisting fabric, prevents body surfaces from wearing.

Fig. 2 is the structural schematic diagram of net in the utility model embodiment two.

Specific implementation mode

The utility model is described in further detail below by specific implementation mode combination attached drawing.

Embodiment one

The utility model provides a kind of net, as shown in Figure 1, the net ball body main body 1 uses foam sphere, the bubble The inner hollow of foam sphere, that is, 1 center of main body forms a cavity 2.The outer surface of main body 1 is equipped with clad 4, changes cladding Layer is fabric, and clad 4 can effectively prevent the abrasion of foam sphere.Ball will produce certain shape in impact Become, to which the air inside extrusion chamber generates the power of a rebound, which adds the elasticity of ball body so that ball body flies Initial velocity bigger.In order to solve this problem, the first air hole 3 is distributed between 1 outer surface of cavity 2 and main body, first is ventilative Hole 3 is centrosymmetric distribution with respect to the centre of sphere.By the way that the first air hole 3 is arranged so that the air in cavity 2 can not compress, to The elasticity for reducing ball body, to reduce impact ball body initial velocity.

Net given by the present embodiment, ball body main body uses foam, opposite to be reduced with traditional rubber tennis Ball body weight, body interior is hollow in addition so that on the basis of reducing weight, size of main body can be done more ball Greatly.A diameter of 9cm of traditional tennis diameter net usually in 6.5-6.5cmm, the present embodiment.Reduce the weight of ball body Its inertia can be reduced, increase ball body size and then increase the air drag being subject to when its flight so that net is being detached from ball Flying speed die-offs after bat so that player is easier to receive, and has also catered to the small feature of net athletic ground area.Due to adopting With this structure design, after the dynamics of net square stance reaches a certain level, since tennis ball body inertia is low, air drag Greatly, lead to influence very little of the amplification of strength to tennis range ability itself, play a kind of be similar to and throw away one piece of plumage in air The effect of hair, thus player's square stance need be not excessively the problem of worrying batting out-of-bounds, need not also use prodigious strength, enhancing The leisure of net campaign is interesting so that the movement is suitable for people of all ages.Since net body weight mitigates, elasticity reduces, This reduces net to hit the vibrations that racket generates so that the net has splendid incabloc function.

Embodiment two

Since the ductility of foamed material is limited, excessive deformation can not be born, thus, it is excessive in impact strength When, the inside deformation quantity of main body 1 is excessive to may result in ball body fragmentation, does not solve the problem, the present embodiment is in embodiment one On the basis of improved.As shown in Fig. 2, in the present embodiment, a hollow ball is added in the cavity 2 of 1 center of main body Core 5.The ball 5 is the PE hollow balls of 1mm thickness, and air hole 6 is distributed in surface.In the outer surface diameter and cavity 2 of ball 5 Diameter is identical so that 5 outer surface of ball is fitted closely with 2 inner surface of cavity, and is complex as the two by ultrasonic wave complex technique One, it is of course also possible to use other adhering techniques, 5 outer surface of ball is fixedly connected with 2 inner surface of cavity.5 surface of ball Provided with second air hole 4 corresponding with the first air hole 3, prevent the air in ball 5 from being compressed in impact.

In the present embodiment, due to being provided with the ball 5 of PE materials, in the case where receiving moment extruding force, ball in cavity 2 Core 5 plays the role of skeletal support, prevents foam sphere from inwardly generating large deformation, breakage occurs so as to avoid main body 1, makes It is whole more sturdy and durable to obtain net.

The utility model provides a kind of net, relatively traditional by setting ball body main body to hollow foam Tennis not only reduces ball body weight, while ball body diameter can do more, and is increased in net flight course with this The air drag received, to reduce net-fault velocity of shuttle flight；Body interior setting body interior ball can prevent from batting When the excessive deformation of main body caused by foam globules rupture, increase net service life；Air hole is arranged in main body and ball surface, So that air can not compress in cavity when ball figure becomes, from the elasticity for reducing ball body, reduce the initial velocity of impact, simultaneously It also reduces net and hits the vibrations that racket generates so that the net has splendid incabloc function；Body surfaces coat Wear-resisting fabric, prevents body surfaces from wearing.

The above content is combine specific embodiment further detailed description of the utility model, and it cannot be said that The specific implementation of the utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field For, under the premise of not departing from the present utility model design, a number of simple deductions or replacements can also be made.
