Problems solved by technology

[0003] The connection between the aluminum alloy racket frame and the handle is connected by a three-way pipe or other connecting parts. Because the three-way pipe is glued to the sleeve, it is difficult to withstand the stress and torque generated when hitting the ball.

Embodiment Construction

[0013] Figure 1 shows the overall shape of the racket, which is basically the shape of a racket with a wire hitting surface, and this diagram is more similar to a tennis racket. The racket consists of racket frame 1 and handle 4 in two parts. The cross section of the racket frame is a hollow shape with two layers of keels. Figure 2 shows the connection between the two lower arm end faces of the racket frame 1 and the front end of the handle 4, the connection between the lower end of the racket frame and the front end of the flat handle (4), and the shock absorber. The position and shape of the rivet 7 of the block 5 are clearly shown in Figure 2-A. The lower arm end 3 of the racket frame 1 is inserted into the handle 4. Figure 4 shows that the cross-sectional shape of the handle 4 is a flat octagonal thin-walled tubular shape, and its front The segment gradually shrinks and is tightly connected to the two lower arm ends 3, which makes the combination more compact. Two round ho...

Abstract

An Al-alloy racket with high strength and vibration damping effect and light weight is composed of a tubular frame made of Al alloy and with 2 joist layer, a vibration damping block between two lower arms of said tubular frame, and an octagonal handle connected to said two lower arms of said tubular frame via two rivets and with a surficial fiber layer.

Description

technical field [0001] The invention belongs to sports equipment, in particular to a racket with a net-shaped string hitting surface. Background technique [0002] In ball sports, rackets with mesh strings, such as tennis, badminton, and squash, require a combination of rigidity and shock absorption. The material, structure and weight of the racket are important factors, of course. There are also the mechanical properties of the racket material, and the price / performance ratio it reflects. The racket is made of metal (aluminum, alloys and even titanium alloys) and fibers, or a hybrid. The difference in racket material is closely related to the weight and quality of the racket. Titanium alloys have good performance, but are expensive. Carbon fiber is heavier. The fiber-aluminum alloy hybrid type is better, but its cost is high and the processing technology is difficult. All aluminum alloys have problems with the overall strength and weight of the racket. [0003] The con...
