Abstract

The utility model relates to a bat sport equipment technical field, in particular to a bat with a beam on the cross section of a bat frame. The utility model is characterized in that a beam is arranged on the cross section which is placed at the head frame of the bat. The utility model has the advantages that the utility model is used in guy lines, net lines can be threaded alternately from the cavities at the two sides of the beam and go cross the beam, so the net lines are more easily to be tightened; the stress on the bat frame is more even; the elasticity, the anti-twist property and the rigidity of the bat are better; the net lines can be pulled more tightly, so the power of ball-hitting or hitting back of the bat is larger; and the use circle is prolonged. The utility model is suitable for producing tennis bats, wall ball bats, battledores, force-back bats and other various bats.

Description

The racket of frame cross section band crossbeam

Technical field:

The utility model relates to racket type games equipment technical field, refers in particular to the racket of a kind of frame cross section band crossbeam.

Background technology:

As everyone knows, traditional racket, comprise tennis racket, wall ball racket, racket, return rackets such as power bat, generally all form (referring to Fig. 1) by the head frame 10 and the handle 20 of racket, on the head frame 10 of racket, offer the backguy hole, and formed the racket driving part of forming by framework 10 and netting twine by the part that backguy surrounds the head frame 10 of racket, racket is when backguy, the tension force of line directly acts on the racket, the structure of racket and span wire system have determined the highest netting twine pulling force that racket can bear, but, be subjected to the traditional racket structure and the restriction of span wire system, the netting twine pulling force of racket can not be exerted oneself too big, caused the batting or the return of serve power of racket can not perform to maximum, simultaneously, along with the racket growth of service time, the pulling force of netting twine diminishes gradually, like this, the initial less racket of netting twine pulling force also just earlier near out of use state, shortens the life cycle of racket accordingly, and for the user, the racket that anti-higher net is pressed also just means to have bigger batting power and more permanent service time, and therefore, the racket that anti-higher net is pressed also just becomes user's ideal to be pursued and preferred object.

Summary of the invention:

The purpose of this utility model is to change traditional frame of racket cross section structure, on the cross section of frame, crossbeam is set, make the support force of frame bigger, make racket have bigger elastic force and intensity, easier of the netting twine tension when backguy, and then form racket with anti-higher net pressure, to increase athletic batting or return of serve power, simultaneously, make the life cycle of racket longer.

The utility model is achieved in that the racket of frame cross section band crossbeam, it is characterized in that the cross section of racket head framework is provided with crossbeam.

Above-mentioned crossbeam can be provided with or whole setting in the part of racket head framework.

Above-mentioned crossbeam can be the straight line trend, also can be curved course.

Draw on above-mentioned racket head framework and be provided with netting twine, netting twine leap crossbeam draws to be established.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model is because when backguy, and netting twine 30 is from threading alternately between two cavitys 101 or 106,104 or 107, and strides across crossbeam 102 or 105, make crossbeam 102 or 105 bear most netting twine tension force, so stressed littler, more even on the frame, make racket more durable.

2, the utility model is made into the structure that has crossbeam 102 or 105 with the head frame 10 of racket, make the elasticity and the rigidity of racket better, during backguy, can apply bigger power netting twine 30, with netting twine 30 draw tighter, and then make racket batting or the return of serve power bigger.

3. be made into the structure of band crossbeam 102 or 105 because of head frame 10 of the present utility model, make at square stance, the torsional property of frame is better than common cavity structure.

4, since netting twine 30 can be drawn tighter, the leeway that netting twine 30 is fluffed gradually is littler, therefore, can make the life cycle of the racket that the utility model makes longer.

5, the utility model is applicable to various types of rackets such as making tennis racket, wall ball racket, racket, time power bat.

The specific embodiment:

With specific embodiment the utility model is further described below:

Referring to Fig. 1-8:

There is the racket of crossbeam in the frame cross section, the cross section band crossbeam 102 or 105 structures that it is characterized in that racket head framework 10, the purpose that crossbeam 102 or 105 are set is: make crossbeam 102 or 105 bear most netting twine tension force, stressed more even on the frame makes racket more durable.

Above-mentioned crossbeam 102 or 105 can be provided with or whole setting in the part of racket head framework 10, and local the setting is in order to make racket torque when batting or return serve bigger, to make ball-handling easier in framework 10 outsides of racket head.

The cross section crossbeam 102 of above-mentioned racket head framework 10 or 105 effect are elasticity and the rigidity in order to increase racket, during backguy, can apply bigger power to netting twine 30, with netting twine 30 draw tighter, and then make racket batting or the return of serve power bigger.

Above-mentioned crossbeam 102 or 105: can be the crossbeam 102 of straight line trend, also can be the crossbeam 105 of curved course, when crossbeam 105 is curved course, can make the batting of racket or return of serve power bigger.

Draw on above-mentioned racket head framework 10 and be provided with netting twine 30, netting twine 30 is crossed over crossbeams 102 or 105 and pass backguy hole 103 on the framework 10 and draw and establish.

Making of the present utility model: make a pre-type by the material of carbon fibre composite or other material earlier, put into punching block again with given shape, utilize the internally pressuring shaping method to mold semi-finished product 10,20, wherein: racket head framework 10, whole or local hollow space at framework 10 is provided with crossbeam 102 or 105, the crossbeam 102 that crossbeam can be in line and move towards, also can make the crossbeam 105 of curved course, during backguy, netting twine 30 can be striden across crossbeam 102 or 105, penetrate backguy hole 103 and weave, and with netting twine 30 tensions.

The utility model can be applicable in various types of racket manufacturings fields such as tennis racket, wall ball racket, racket, time power bat.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
