Description of the embodiments
Referring to fig. 1 to 3, a preferred embodiment of the present utility model is shown, which comprises an inner rod 10 and an outer rod 20.
The inner rod body 10 is made of fiber or aluminum-titanium alloy. The inner rod 10 has a hollow structure (shown in fig. 2), however, the inner rod 10 may have a solid structure (shown in fig. 3), which is not limited thereto and may be selected according to the requirement; the fiber material is carbon fiber or glass fiber; the cross section of the inner rod 10 is circular, but other shapes are also possible, not limited thereto.
The outer rod 20 is coated outside the inner rod 10, the outer rod 20 is made of aluminum-titanium alloy or fiber material, and the outer rod 20 and the inner rod 10 are made of different materials, namely: when the outer rod 20 is made of aluminum-titanium alloy, the inner rod 10 is made of fiber; when the outer rod 20 is made of fiber, the inner rod 10 is made of aluminum-titanium alloy.
The outer rod body 20 and the inner rod body 10 are assembled together in a tight fit manner. The outer rod body 20 and the inner rod body 10 are combined together in an insert molding mode, so that the combination is more stable. When the outer rod 20 is made of aluminum-titanium alloy, concave-convex lines 21 are formed on the outer wall surfaces of the two ends of the outer rod 20 through knurling, so that the two ends of the outer rod 20 are combined with the handle and the racket frame respectively more firmly and reliably. When the outer rod 20 is made of an aluminum-titanium alloy, the outer rod 20 is a seamless tube, so as to better prevent the product from breaking, and of course, the outer rod 20 may be a seamless tube, which is not limited thereto.
During manufacturing, there are two modes: one way is to manufacture the inner rod body 10 and the outer rod body 20, and then insert the inner rod body 10 into the cavity of the outer rod body 20 to be tightly matched and fixed. Another way is in two cases: if the inner layer rod body 10 is made of fiber, firstly preforming the inner layer rod body 10 and manufacturing the outer layer rod body 20, then inserting the preformed inner layer rod body 10 into a cavity of the outer layer rod body 20, and finally heating and solidifying the inner layer rod body 10; if the inner rod body 10 is made of an aluminum-titanium alloy material, the inner rod body 10 is manufactured, the outer rod body 20 is preformed, the outer rod body 20 is coated outside the inner rod body 10, and finally, the outer rod body 20 is heated and solidified.
When the novel racket is used, two ends of the novel racket are respectively connected and fixed with the racket frame and the handle, when the outer layer rod body 20 is made of aluminum-titanium alloy materials, the novel racket has good torsion resistance, and when the outer layer rod body 20 is made of fiber materials, the novel racket has good rigidity.
