Technical Field

The present invention relates to a racket, and more particularly to a racket structure for reducing vibration and increasing elasticity.

Background

The hockey is a sport combining tennis, badminton and billiards. The ball is like a tennis ball, but is a thin-shell hollow ball made of hard plastic, and a plurality of openings are distributed on the outer surface of the ball. The racket is a large table racket, which includes a racket body and a handle, and is traditionally made of wood, which is heavy, so that a comparatively light Polypropylene (PP) honeycomb board is developed to cover the carbon fiber cloth to form a picket racket.

However, although the acrylic racket made of polypropylene honeycomb board has the advantage of light weight, the shock transmitted to the racket handle during hitting the ball is large, the elasticity generated during hitting the ball is also poor, and loud and high-frequency sounds are generated during hitting the ball, so that noise is easily generated in a specific environment, such as when playing the acrylic ball in a community house, and troubles are caused. In view of the above, the present inventors considered that further improvement of the conventional picket racket is necessary.

Further, the coating material can be one of carbon fiber cloth or glass fiber cloth.

Further, the foam core material is arranged at the middle position of the plate body, namely the sweet area position of the hitting ball.

Furthermore, the foaming core material is made of High energy adhesive (High energy adhesive), which is a preformed core material and has controllable expansion force under the action of certain High temperature and a period of time.

Further, the structural unit is configured as a single-layer structure.

Furthermore, the cross section of the structural unit is hexagonal, so that a honeycomb structure is formed.

Further, the plate body is integrally made of Polypropylene (PP), and the bottom layer and the top layer are Non-woven fabrics (Non-woven fabric).

Detailed Description

Referring to fig. 1 to 3, a racket structure for reducing vibration and increasing elasticity is disclosed. The racket comprises a racket body and a handle, wherein the racket body comprises:

a plate body 10, which is composed of a plurality of structural units 11, the cross section of each structural unit 11 is hexagonal, and the structural units 11 are closely arranged in an array. In the preferred embodiment of the present invention, the structural units 11 are configured as a single layer structure, and the plate 10 has a through hole 12 penetrating vertically in each structural unit 11, and the cross section of the through hole 12 is hexagonal, so that the plate 10 forms a honeycomb structure. The plate body 10 is integrally made of Polypropylene (PP), has flexibility, and can effectively prolong the stay time of a hockey ball on the racket face when the hockey ball is hit, thereby improving the ball control capability and further providing the shock absorption effect. The board body 10 with a honeycomb structure not only can maintain the structural strength of the picket racket, but also can effectively reduce the overall weight of the picket racket, so that the swinging of the picket racket is more labor-saving and easier.

A bottom layer 20, which is disposed on the bottom side of the plate body 10 and can seal the bottom of the through holes 12. In the preferred embodiment of the present invention, the bottom layer 20 is made of Non-woven fabric (Non-woven fabric), and can be integrated with the plate 10 by hot pressing.

A plurality of foam core materials 30, it locates in the perforation 12 of preset position respectively, and the bottom surface of this foam core material 30 supports this bottom 20, this foam core material 30 can be set up in the perforation 12 of this plate body 10 arbitrary position department as required selection, can punch 12 and set up foam core material 30 by local, also can punch 12 and all set up foam core material 30 by whole, in the preferred embodiment of the utility model, this foam core material 30 sets up in the perforation 12 that the department distributes in the middle of this plate body 10, is also the position in the so-called batting sweet district promptly. The foam core 30 has the characteristic of foam molding at High temperature, in the preferred embodiment of the present invention, the foam core 30 is made of High energy adhesive (High energy adhesive), which is a preformed core, and has controllable expansion force under the action of certain High temperature and a period of time.

A top layer 40 disposed on the top side of the board body 10, wherein the top surface of the foam core 30 is pressed against the top layer 40. And the top layer 40 closes the top of the through holes 12. In the preferred embodiment of the present invention, the top layer 40 is also made of non-woven fabric, and can be integrated with the plate body 10 by hot pressing.

A coating material 50, on the outer peripheral face of this racket main part of its cladding, this coating material 50 can be one of them for carbon fiber or glass fiber material, in the utility model discloses in the preferred embodiment, this coating material 50 is carbon fiber material, can effectively strengthen the structural strength of racket main part, makes racket main part can bear the strike of certain degree, avoids it because of receiving the striking and damage, and can also increase the frictional force of racket face and picket ball when batting, improve the rotational speed of picket ball to hand when further optimizing and waving.
