Abstract
The utility model discloses a combination type guard against error strip, including a hard strip nail with a nail tube. The hard strip nail is made by a hard material, and the left and right two sides at the root of the hard strip nail is provided with a convex rib; An external sleeve is provided with a soft nail tube with a lug boss, and the soft nail tube is made by a soft material. The left and right two sides at the root of the soft nail tube is provided with a hollow part, and the hollow part and the convex rib of the hard strip nail is corresponding. This structure not only has the earthquake avoidance function, but also can avoid not being hurt by the soft nail tube.
Description
Technical field
The utility model relates to a kind of racket combined type guard strip.
Background technology
As everyone knows, general racket (comprising tennis racket, wall ball racket or pelota bat etc.) all includes frame and lever, then is equipped with some lines hole at the periphery of frame, in order to wear the guard strip of nail pipe or band nail pipe, puts on netting twine again, thereby constitutes wire side.The setting of guard strip is then to prevent that netting twine from directly contacting with the line hole of frame, is not cut off with the protection netting twine, can also keep the tension force of netting twine simultaneously.
In the prior art, the guard strip of racket often uses plastic cement or nylon material, this material is harder, wear-resistant, can prevent the netting twine fracture, yet the vibrations that the guard strip of hard material produces batting are difficult to absorb, and promptly behind the ball impact wire side, the nail pipe that netting twine drives guard strip directly impinges upon on the frame, cause shock wave along frame, lever, be delivered to user's arm and shoulder, make the user feel under the weather, the time one also can produce " tennis elbow " motion phenomenon for a long time.
For the netting twine shock transfer that reduces the generation of batting back arrives frame, there is the dealer to adopt soft bar nail (as thermo plastic rubber), or being provided with a soft nail pipe in the outside of hard nail pipe, this material helps the absorption that shakes, thereby the shock wave that is delivered to arm is significantly reduced.Yet, because racket in use for some time, netting twine can move up and down, and netting twine all will keep certain force of strain after tightening, this tension force makes the netting twine can self-return after moving, thereby make netting twine oppress the left and right sides (as shown in Figure 1) of relative bar nail, cause bar to clench to compel the acute angle place, edge in frame line hole and wear and tear, even damage to the terminal, and once the fracture of bar nail will not have the function of shock-absorbing, and, if its inside is not provided with hard nail pipe again, then netting twine will directly contact with the line hole, and easily makes the netting twine fracture.
The utility model content
The purpose of this utility model is to provide a kind of racket combined type guard strip, and it not only has incabloc function, also can prevent the fracture of non-magnetic shim pipe.
For achieving the above object, technical solution of the present utility model is: a kind of combined type guard strip, comprise that the runner of a band nail pipe is followed closely, and this runner nail is made for hard material, and left and right sides of its nail pipe root is provided with the protrusion rib; And its outer soft nail pipe that is with a band boss, this soft nail pipe is that soft material is made, and the left and right sides of its root is made as hollow-out parts, this hollow-out parts is corresponding with the protrusion rib that runner is followed closely.
The nail pipe of this runner nail is arranged on the bar, and the outside of this bar is provided with the duct that holds netting twine.
The boss of the soft nail pipe of each of described combined type guard strip is linked to each other by connecting portion; And this boss and connecting portion can one-body moldedly be the bar of a whole piece, and this bar and soft nail pipe constitute soft nail.
After adopting said structure, the structure that soft, hard two bars are followed closely because the utility model adopts, and the nail pipe root both sides at runner nail and soft nail are respectively equipped with protrusion rib and hollow-out parts, and because the square stance netting twine is a fore-and-aft direction to the action direction of following closely pipe, so the shock wave major part that the ball impact wire side is produced is absorbed by the tube wall of the nail pipe fore-and-aft direction of soft nail, thereby reduce the vibrations of arm, to reach the effect of shock-absorbing; And when netting twine is offset; it then is the left and right directions skew of following closely pipe relatively; because about the nail pipe root of soft nail is hollow out; therefore the compressing power of netting twine makes the protrusion rib of runner nail directly contact with the line hole of frame, and the material of runner nail is harder, is difficult for being cut off; thereby protection netting twine; avoid because of the moving of high pressure and square stance netting twine, and contact with the sharpened edge in frame line hole and hurt the nail pipe of soft nail, and then protect netting twine.

The specific embodiment
Shown in Fig. 2,3, combined type guard strip described in the utility model comprises 1 and one soft nail 2 of runner nail.Wherein:
At the outer soft nail pipe 22 that is with a band boss of the nail pipe 12 of the nail of bar more 1, the left and right sides that this soft nail is managed 22 roots is made as hollow-out parts 23, and it is corresponding that this hollow-out parts 23 and runner are followed closely 1 protrusion rib 13; And the boss of each soft nail pipe 22 is linked to each other by connecting portion, and boss and connecting portion also can one-body moldedly be the bar 21 of a whole piece, and this bar 21 and soft nail pipe 22 constitute soft nail 2; This soft nail 2 made by softer material, as natural rubber, synthetic rubber or plasticity elastomer etc.
During assembling, as shown in Figure 4, the nail pipe 12 of runner nail 1 is placed in the nail pipe 22 of soft nail 2, and make the protrusion rib 13 of runner nail 1 snap in the hollow-out parts 23 of soft nail 2,, pass the line hole 31 of frame 3 with nail pipe 22, and then penetrate netting twine 4 again with whole guard strip.
The racket square stance that has described combined type guard strip in use, because netting twine is a fore-and-aft direction to the action direction of nail pipe, therefore the shock wave major part that produced of the ball impact wire side tube wall of being managed 22 fore-and-aft directions by the nail of soft nail 2 absorbs, thereby reduces the vibrations of arm, to reach the effect of shock-absorbing.And when netting twine 4 skews; it then is the left and right directions skew of following closely pipe relatively; because about the root of soft nail 2 nail pipes 22 is hollow out; therefore the compressing power of netting twine 4 makes the protrusion rib 13 of runner nail 1 directly contact with the line hole 31 of frame 3, and the material of runner nail 1 is harder, is difficult for being cut off; thereby protection netting twine 4; avoid because of the moving of high pressure and square stance netting twine 4, and contact with the sharpened edge in frame 3 line holes 31 and hurt netting twine 4, influence the function of racket.
In addition, this combined type guard strip can be installed in the center position (left and right sides of frame) of frame of racket, or the top of frame and bottom (month eyebrow position), also can put in order frame certainly and all be provided with.And described protrusion rib 13 is not that each relative nail pipe 12,22 all is provided with hollow-out parts 23, as long as easily be provided with on the nail pipe 12,22 of skew at netting twine, each relative nail pipe 12,22 all is provided with and protrudes rib 13 and hollow-out parts 23 also can certainly.
Please cooperate shown in Figure 5 again, for originally being combined type guard strip with the two bar nails of soft or hard, its structure just as shown in the figure, the nail pipe of this runner nail is shorter, and the nail pipe of soft nail is longer, and inwardly contract to identical with the nail pore footpath of runner nail in the aperture of the nail pipe lower end of soft nail, its improvements are to be respectively equipped with protrusion rib and hollow-out parts in the nail pipe root both sides of runner nail and soft nail equally, to reach shock-absorbing and to prevent the purpose that soft nail cuts off.
