Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.

In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

Embodiment one:

referring to fig. 1-4, a shock-absorbing racket with large disturbance degree comprises a racket frame 1 and a grab handle 2, wherein a handheld part 21 and a connecting part 22 for connecting the racket frame 1 are arranged on the grab handle 2, and a foam outer cover 4 is sleeved outside the connecting part 22. The hand-held part 21 comprises a protective layer 211 positioned at the outer part and a reinforcing layer 212 positioned at the inner part, a spacing space is formed between the protective layer 211 and the reinforcing layer 212, a buffer layer 213 is filled in the spacing space, and the cross section area of the connecting part 22 is smaller than the cross section area of the protective layer 211. The moment of the section is reduced by abrupt change of the section, the deformation disturbance of the frame is increased, the integral deformation of the racket is increased, the ball stays in the racket for a longer time, the ball is more beneficial to controlling the direction of the ball, the ball outlet speed is faster, and meanwhile, the ball rotates faster in the flying process. And, the connecting part 22 is wrapped outside the foam outer cover 4 to absorb the energy transferred from the racket frame to the grab handle, thereby achieving the shock absorbing effect.

Specifically, the racket frame further comprises a triangular area 3 for connecting the racket frame 1 and the grab handle 2, and the triangular area 3 and the connecting part 22 are integrally formed.

The connecting part 22 comprises a first connecting section 221 and a second connecting section 222, the first connecting section 221 is connected with the throat part of the triangular region 3, and the cross section area of the first connecting section 221 gradually decreases in the direction away from the racket frame 1 until the cross section area of the first connecting section 221 is the same as that of the second connecting section 222. The second connection section 222 is connected to the reinforcing layer 212, and the section of the second connection section 222 is the same as the section of the reinforcing layer 212. That is, the second connection section 222 and the reinforcing layer 212 are both in a uniform column shape or a cylindrical shape, and the two connection parts do not form abrupt cross-section changes, so that the energy transferred from the racket surface is directly transferred to the reinforcing layer 212 through the connection part 22, and then sequentially passes through the buffer layer 213 and the protective layer 211 from inside to outside. When the force on the frame is transferred to the innermost layer of the handle, the force is damped through the middle layer and then transferred to the outermost layer, and finally transferred to the hand. The whole transmission process, the buffer layer in the middle absorbs most energy, so that the effect of not shaking hands is achieved, and meanwhile, the outermost layer is a hard protection layer, so that the hand-held touch feeling is not affected.

In this case, the end of the protective layer 211 near the racket frame 1 is provided with an inclined surface 214 connected with the reinforcing layer 212, which is compared with the angle abrupt change of the horizontal and vertical angles, so as to avoid the impact damage of energy to the joint structure in the conduction process. The inclined surface 214, the second connection section 222 and the first connection section 221 are sequentially connected to form a ring groove for installing the foam outer cover 4, so that the foam outer cover 4 is installed more stably.

Preferably, the thickness of the interval spaces located at the front and rear sides of the racket frame 1 is greater than the thickness of the interval spaces located at the left and right sides of the racket frame 1. Because the front and back sides of the racket body are stressed most when the racket is used, the impact energy received on the front and back sides is larger, the racket is required to be damped relative to thicker buffer layers arranged on the left and right sides, if the front and back damping is insufficient or the lateral damping materials are too much and waste cost is caused if the front and back damping is the same in thickness. A plurality of reinforcing ribs 215 are uniformly arranged between the protective layer 211 and the reinforcing layer 212 in a surrounding manner so as to realize the connection between the protective layer 211 and the reinforcing layer 212 and improve the structural strength.

In this embodiment, the buffer layer 213 is made of soft PU material, and the foam cover 4 is made of hard PU material. The protective layer 211 and the reinforcing layer 212 are carbon yarn layers.

Embodiment two:

on the basis of the first embodiment, please refer to fig. 5-6, the device further comprises an adjusting assembly 5, wherein the adjusting assembly 5 is detachably mounted between the left yoke 31 and the right yoke 31 of the triangle 3, so that a user can select to put or not put the device independently. When the adjusting component 5 is selected and installed, the distance between the throat part of the triangular area 3 and the moon brow is shortened, the integral torsion resistance of the racket is improved, and the racket is more stable. The adjusting component 5 comprises a U-shaped counterweight piece 51, locking blocks 52 and locking bolts 53, wherein the outer walls of the two sides of the U-shaped counterweight piece 51 are respectively matched with the yoke part 31, the locking blocks 52 are clamped into U-shaped grooves of the U-shaped counterweight piece 51, the locking blocks 52 are fixed with the U-shaped counterweight piece 51 through the locking bolts 53, and the locking blocks 52 press the U-shaped counterweight piece 51 to deform towards the two sides, so that the U-shaped counterweight piece 51 is fixedly extruded between the yoke part 31.

Specifically, opposite sides of the yoke 31 on the left and right sides are provided with convex arcs, the outer walls on the two sides of the U-shaped weight piece 51 are provided with first grooves 511 corresponding to the convex arcs, and when the first grooves 511 are engaged with the yoke 31, the U-shaped weight piece 51 is limited. The inner side walls at two sides of the U-shaped groove of the U-shaped counterweight 51 are provided with convex arc portions 512, the two side walls of the locking block 52 are provided with second grooves 521 corresponding to the convex arc portions 512, and when the convex arc portions 512 are clamped with the second grooves 521, the U-shaped counterweight 51 is limited with the locking block 52. Meanwhile, the convex structure is matched with the concave structure, so that the installation guiding effect can be realized.

The section of the U-shaped groove of the U-shaped counterweight member 51 is in an inverted trapezoid shape, so that the locking block 52 has an inverted trapezoid structure adapted to the U-shaped groove. The length of the bottom edge of the locking block 52 is longer than that of the U-shaped groove of the U-shaped counterweight piece 51, the relative position between the locking block 52 and the U-shaped counterweight piece 51 is controlled through the screwing degree of the locking bolt, and then the expansion deformation degree of the two side walls of the U-shaped counterweight piece 51 is controlled, so that the bending or torsion degree of the whole racket in a triangular area can be directly influenced (namely, the integral rigidity of the racket is different), and a consumer can adjust the locking degree according to the self requirement, so that the racket is more stable and more powerful when in use. In this embodiment, the U-shaped weight member 51 may be designed with different weights to make different appearances, and the adjustment of the weight and the shape of the racket may be achieved by replacing the U-shaped weight member 51, so as to satisfy different demands of consumers.

The bottom of the U-shaped counterweight piece 51 is provided with a threaded hole 513, the locking block 52 is provided with a mounting hole 522, and the locking bolt 53 sequentially penetrates through the mounting hole 522 and the threaded hole 513 to fix the U-shaped counterweight piece 51 and the locking block 52. Meanwhile, a limit groove 523 corresponding to the head of the locking bolt 53 is provided at the upper part of the mounting hole 522, and when the locking bolt 53 is screwed, the head collides with the bottom of the limit groove 523. When the head of the locking bolt 53 is placed in the limit groove 523, the loosening of the bolt in the use process caused by the external force acting on the head can be reduced or avoided through the protection of the groove structure, so that the structural stability is further ensured.

Embodiment III:

on the basis of the first embodiment or the second embodiment, referring to fig. 7, a plurality of elongated hollow holes 32 are symmetrically disposed on the left and right yokes 31 of the triangle 3, and the elongated hollow holes 32 penetrate through the front and rear sides of the yokes 31, so that when the swing is performed forward and backward, the resistance surface is reduced due to the arrangement of penetrating through the long holes, the wind resistance can be reduced, and the swing speed is faster. Meanwhile, the yoke part is changed into two sections from one section, the lateral section moment is reduced, the lateral bending disturbance is increased, the whole racket is softened laterally, the ball stays on the racket surface for a longer time, and the ball rotates faster in the air flying process after leaving the racket.

In this embodiment, two elongated hollow holes 32 are provided on the yoke 31 on one side, and the elongated hollow holes 32 are sequentially arranged along the axial direction of the yoke 31, so that enough hollow portions are provided on the yoke 31, and meanwhile, too low strength of the yoke 31 is avoided. Specifically, the end of the elongated hollow hole 32 located at the upper side is close to the moon-shaped eyebrow 33 of the triangular area 3, the end of the elongated hollow hole 32 located at the lower side is close to the throat 34 of the triangular area 3, and a solid portion is formed between the two elongated hollow holes 32. Meanwhile, the length of the elongated hollow hole 32 on the upper side should be shorter than that of the elongated hollow hole 32 on the lower side, and since the yoke 31 is spaced less on the side close to the throat 34, a larger hollow area is required to reduce the wind resistance.

Preferably, the width of the elongated hollow hole 32 is 1/7-1/6 of the width of the yoke 31, so as to ensure the structural strength of the yoke 31 and simultaneously form a better drag reduction effect.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, and various modifications and variations may be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
