Detailed Implementation

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1-3 A manufacturing process for a vibration-damping baseball bat includes a bat body 101 and a grip handle 102 fixed to the rear side of the bat body. An end cap 10 is fixed to the end of the grip handle. A shock absorber 20 is built into the middle of the end cap 10. The shock absorber includes a central mass component 210 and an elastic component 220 fixed to the outer periphery of the central mass component.

[0027] In this embodiment, the central mass component 220 is placed inside an outer sleeve 230, the outer surface of the elastic component 220 is in contact with the outer sleeve 230, and the outer sleeve 230 is fixedly connected to the middle of the end cap 10.

[0028] The outer surface of the outer tube 230 is closed, and the end cap 10 has a groove 110 in the middle for embedding the outer tube 230. A shock absorber 20 is placed inside the outer tube 230.

[0029] In actual use, after the shock-absorbing component is placed inside the outer tube 230, the outer tube 230 is bonded and fixedly connected to the sink 110.

[0030] In this embodiment, the elastic element 220 is toothed to improve its shock absorption capacity. The elastic element 220 and the central mass element 210 can be fixed together by adhesive bonding.

[0031] The end cap 10 includes a circular end cap 120 at the tail end. The circular end cap 120 is fastened into the tubular rear end of the striking rod body 101, and is generally bonded to the striking rod body with glue, but can also be fixed with a threaded structure. Finally, the surface of the shock absorber 20 is glued and then inserted, with the closed end of the outer sleeve 230 of the shock absorber 20 facing outward to ensure that the elastic element and the central mass element do not come out.

[0032] In one embodiment of the present invention, the end cap 10 has a protrusion in the middle that snaps into the rear of the grip handle, and the recess 110 is located outside the plug 130.

[0033] A circular end cap 120 extends forward to a buckle tube 140, and a cavity 141 is formed between the buckle tube and the plug body to be fastened into the rear end tube of the striking rod.

[0034] like Figure 1 and 4 As shown in Figure 7, in one embodiment of the present invention, the striking rod body 101 and the grip handle 102 are manufactured separately. The front end of the grip handle 102 is fitted onto the tail end of the striking rod body 101. The front end of the grip handle is wrapped with a first annular elastic body 30 extending into the striking rod body and a damping protrusion 310 arranged circumferentially on the front surface of the first annular elastic body 30. The rear end of the striking rod body 101 is fixedly connected to the front end of the grip handle 102.

[0035] In one embodiment of the present invention, the inner diameter of the rear part of the striking rod 101 gradually decreases from the front to the rear, the front end of the grip handle 102 gradually decreases from the rear to the front, and the first annular elastic body 30 is fitted onto the front end of the grip handle.

[0036] The inner diameter of the rear part of the striking rod 101 gradually decreases from the front to the rear, similar to a conventional structure. This design is to ensure that the first annular elastic body 30 and the damping protrusion 310 on its surface can reach the required design thickness. In addition, the outer peripheral surface of the first annular elastic body 30 and the damping protrusion 310 on its surface can fit the shape of the inner wall of the striking rod 101 to facilitate the transmission of vibration.

[0037] In this embodiment, the outer surface of the damping protrusion 310 is inclined from the front to the rear, and the damping protrusion is strip-shaped or wavy. The first annular elastomer and the damping protrusion 310 are integrally formed.

[0038] The outer surface of the damping protrusion 310 is inclined from the front to the rear to adapt to the conical inclined surface of the rear end of the striking rod 101. The strip-shaped or wave-shaped structure ensures the vibration space of the damping protrusion 310 during the vibration process.

[0039] For ease of positioning, in one embodiment of the present invention, the outer periphery of the rear end of the first annular elastic body has an annular positioning protrusion 320, and the inner cavity of the rear side of the striking rod has a groove that cooperates with the annular positioning protrusion.

[0040] In one embodiment of the present invention, the grip handle 102 is further fitted with a skirt-shaped damping sleeve 40 on the rear side of the first annular elastic body, and the inner surface of the skirt-shaped damping sleeve 40 is bonded to the outer rear wall of the striking rod body 101.

[0041] The dual damping effect of the skirt-shaped damping sleeve 40 and the first annular elastomer 30 can effectively reduce the impact on the connection between the grip handle and the bat during the hitting process, reduce the transmission of impact to the batter's hand, and improve the life of the bat.

[0042] During assembly, the first annular elastomer 30 is first fixed to the front end of the grip handle 102. It can be fixed to the grip handle 102 by utilizing the elasticity of the first annular elastomer 30 itself, or it can be fixed by gluing. Then, the rear end of the grip handle 102 passes through the opening at the front end of the striking rod 101 and the annular positioning protrusion 320 is engaged in the groove 110. Finally, the skirt-shaped damping sleeve 40 is put on the outside of the grip handle 102 and bonded to the outer surface of the grip handle 20 and the striking rod 101.

[0043] In one embodiment of the present invention, the elastic element 220 is made of polypropylene or rubber, the central mass element 210 is made of tubular metal, the Shore hardness of the elastic element 220 is 20A-75A, and the mass of the central mass element is 5-50 grams.

[0044] In the above embodiments, the first annular elastomer material is silicone or rubber with a hardness of 20A-40A, and the skirt-shaped damping sleeve material is silicone or rubber with a hardness of 50A-75A.

[0045] The present invention can effectively and quickly reduce the vibration of the grip by inserting a shock absorber at the end of the bat. The present invention has a simple structure, is easy to assemble, has low cost, and can be applied to situations where the bat body 101 and the grip handle 102 are integrally formed.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
