[0002] With the popularization of billiards, it has now become one of the favorite sports of people. And one of the key factors in billiards is to choose a good billiard cue. The billiard cue is the sports equipment that has the greatest impact on the performance of billiards. Among them, the hitting performance of the billiard cue is its basic requirement, which will directly affect the playing level of the user.

[0003] The applicant applied for a Chinese patent document with the application number 202211580086.0 on December 9, 2022, which discloses a billiard cue for impact extension and acceleration, including a front rod, a cue butt, and an impact ejection acceleration mechanism.

[0025] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0026] As Figures 1 to 4As shown in the figure, the present utility model provides an elastic cue butt for increasing hitting force, which comprises a butt rod 1. The diameter of one end of the butt rod 1 gradually decreases to the diameter of the other end. The butt rod 1 includes a first carbon fiber sheet 2 in a shape of a straight line, two first woods 3 respectively adhered to both sides of the first carbon fiber sheet 2, and two second woods 4 respectively adhered to the sides of the two first woods 3 away from each other. The hardness of the first wood 3 is greater than that of the second wood 4, and the elasticity of the first wood 3 is less than that of the second wood 4. A plurality of elastic deformation gaps 5 are arranged on the outer side wall of the second wood 4, and the plurality of elastic deformation gaps 5 are equidistantly distributed along the length direction of the second wood 4. The elastic deformation gaps 5 are filled with foaming materials 6.

[0027] The present utility model also provides a billiard cue, which comprises a tip 7, a ferrule 8, a forearm rod 9 and the above-mentioned elastic cue butt adhesively connected in sequence from top to bottom. The diameter of one end of the forearm rod 9 gradually decreases to the diameter of the other end. The maximum diameter of the forearm rod 9 is equal to the minimum diameter of the butt rod 1 of the elastic cue butt, and the minimum diameter of the forearm rod 9 is equal to the diameter of the ferrule 8.

[0028] In practical applications, when the tip 7 of the billiard cue hits the cue ball, after the billiard cue receives the reaction force from the cue ball, under the action of the two second woods 4 and the plurality of elastic deformation gaps 5, the elastic cue butt and the whole billiard cue undergo elastic deformation and bend, presenting an arcuate bend and storing elastic potential energy. When released, under the action of the first carbon fiber sheet 2 in a shape of a straight line and the two first woods 3, the elastic cue butt and the whole billiard cue will undergo elastic recovery to convert the stored elastic potential energy into kinetic energy, and the billiard cue will quickly rebound instantaneously to apply a secondary force to the cue ball, so as to achieve the effect of using a small force to move a heavy object and leveraging force to hit, and make the hitting force received by the cue ball increase by more than one time. The present utility model can undergo recoverable elastic deformation during hitting, and can apply a secondary force to hit the cue ball on the basis of the original hitting force of hitting the billiard ball, greatly increasing the hitting force and improving the moving speed of the cue ball.

[0030] In this embodiment, the size of the elastic deformation gap 5 is 0.5 mm to 1.5 mm. When the elastic deformation gap 5 is less than 0.5 mm, the amount of elastic deformation is too small, and the effect of increasing the hitting force is not ideal; when the elastic deformation gap 5 is greater than 1.5 mm, the amount of elastic deformation is too large, and it is difficult to grasp and control the hitting force.

[0031] In this embodiment, the thickness of the first wood 3 is greater than the thickness of the first carbon fiber sheet 2, and the thickness of the first wood 3 is less than the thickness of the second wood 4; the first wood 3 is sandalwood, and the second wood 4 is maple or ash; this structural design is conducive to increasing the hitting force.

[0032] In this embodiment, the outer wall of the rear handle rod 1 is coated with a coating layer, which plays a protective role.

[0034] In this embodiment, an end cap 11 is provided at the end with a larger diameter of the rear handle rod 1; the end cap 11 seals the rear end of the rear handle rod 1, which not only has a beautiful appearance but also plays a protective role for the rear handle rod 1.

[0035] In this embodiment, the front limb rod 9 includes a second carbon fiber sheet 12 in a shape of a straight bar, two third woods 13 respectively glued to both sides of the second carbon fiber sheet 12, two fourth woods 14 respectively glued to the sides of the two third woods 13 away from each other, and two fifth woods 15 respectively glued to the sides of the two fourth woods 14 away from each other. The hardness of the third wood 13 is greater than the hardness of the fourth wood 14, the hardness of the fourth wood 14 is greater than the hardness of the fifth wood 15, the elasticity of the third wood 13 is less than the elasticity of the fourth wood 14, and the elasticity of the fourth wood 14 is less than the elasticity of the fifth wood 15. When the billiard cue hits the ball, both the front limb rod 9 and the elastic rear handle of the cue undergo recoverable elastic deformations, further increasing the hitting force.

[0036] In this embodiment, the third wood 13 is sandalwood, the fourth wood 14 is maple, and the fifth wood 15 is ash, which is conducive to increasing the hitting force.

[0037] In another embodiment, the front limb rod 9 is a carbon fiber rod, which is conducive to increasing the hitting force.

[0038] All the technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
