The utility model content

Technical problem to be solved in the utility model is to propose a kind of bat made from composite (can be carbon fiber or glass fibre) with a flexible plot structure, the bar that sees through the set reduction buckled zone of this barred body directly changes the design with the splendid toughness of its composite wood, can increase and rub control property and can change driving part and the two resonant frequency of extension, to prevent a bat generation resonance of swinging, the athletic injury of arm, elbow or wrist when the minimizing user hits.

The technical solution of the utility model is achieved in that

The utility model relates to a kind of bat with flexible bendable structure, comprise: a driving part, a shank part and are connected with the extension between driving part and shank part, extension between described barred body driving part and the shank part is established a flexible district, this buckled zone bar footpath degree is directly littler than driving part bar, and the bar in this flexible district directly is a hollow structure, and its diameter degree progressively reduces.

Aforesaid bat with flexible bendable structure, described flexible district bar footpath can be made as and be ellipse or outer ellipse interior circular shape in the cylindrical.

The utlity model has following characteristics:

1, prevent to produce resonance and increase to rub control: the utility model is by changing the footpath degree body design between driving part and flexible district and the grip part, limit footpath degree buckled zone can change the two resonant frequency of driving part and extension according to this, to prevent to produce resonance, and then reduce the user and when hitting, cause arm, the athletic injury of elbow or wrist portion, and this bendable tune becomes its rigidity of limit section to reduce, but its toughness can effectively be kept because of the composite factor, its strike of swinging, except that this strike district be difficult for impaired, a pliability state can effectively be released and become to the force-applied dynamics of swinging that adds in this flexible district, can control beating position with its bending point, it is handling preferable.

2, the structure that has toughness: the utility model adopts the integrally formed bat structure of composite, and this flexible district footpath body dwindles, and its rigidity diminishes with respect to hitting the district, and utilizes the characteristic of the splendid toughness of composite, the bat structure good toughness.

3, make easily, structural strength is good: conventional aluminum matter bat is in processing procedure, the system of taking out is difficult for, be difficult for making the flexible plot structure design of set limit of the present utility model, even if can extrude shaping, it causes stress to concentrate easy fracture yet its buckled zone is difficult for into level and smooth shape with the linking end of driving part and shank part, so that overall structure is not good, the utility model is made bat with composite, designing mould in advance, pressurized, heated is shaped again, there is no above-mentioned tradition and take out the difficult problem of system, and collocation composite material strength and the good characteristics of tool toughness, overall structure can be promoted.
