[0028] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0029] Referring to Figures 1-4 A shock-resistant multi-wall structure bat, comprising a hitting rod body 10 and a handle 20 located at the rear side of the hitting rod body, a support rod 30 fixed at the front side of the handle 20 and extending into the hitting rod body, an inner sleeve 40 fixed at the end of the support rod 30 extending into the inner cavity of the hitting rod body, and a gap between the outer surface of the inner sleeve 40 and the inner wall of the hitting rod body.

[0030] In the embodiment, an annular support member 310 is fixed on the support rod 30, and the inner sleeve 40 is fixed to the outer surface of the annular support member 310.

[0031] The rear end of the support rod 30 passes through the lower edge of the hitting rod body 10, and a handle connecting seat 320 is fixed at the rear part of the support rod 30. The rear end of the support rod 30 passes through the lower edge of the hitting rod body 10, and the handle connecting seat 320 is fixed at the rear part of the support rod 30. The two ends of the hitting rod body 10 have openings, and the rear side of the hitting rod body 10 is tapered.

[0032] The handle connecting seat 320 is also tapered, the front end of the handle is larger than the diameter of the rear end opening of the hitting rod body, and the handle connecting seat 320 is limited to the rear end of the hitting rod body 10 and is fixedly connected with the inner wall of the hitting rod body 10.

[0033] The gap is 2-6 mm, and the rigidity of the inner sleeve 40 is greater than that of the hitting rod body.

[0034] When assembled, the inside of the hitting rod body 10 is hollow with both ends open, the rear side of the support rod passes through the front end opening of the hitting rod body 10 until the handle connecting seat 320 is clamped at the end of the hitting rod body 10. At this time, the inner sleeve 40 located on the outer periphery of the support rod 30 is just located at the middle position of the hitting rod body, i.e. the ball hitting area of the bat.

[0035] When assembled, the surface of the handle connecting seat 320 needs to be coated with glue in advance, and after assembly, the handle connecting seat 320 can be glued and fixed in the hitting rod body 10.

[0036] In addition, in the embodiment, the front part of the handle connecting seat 320 can also be fixedly connected with the hitting rod body 10 in a threaded connection manner.

[0037] The rear half of the handle connecting seat 320 is exposed outside the hitting rod body 10 and is used for connecting with the handle 20.

[0038] The present application uses an inner sleeve with high rigidity in the hitting rod body to ensure that the hitting rod body has high rebounding elasticity during the ball hitting process when the bat hits the baseball. When the hitting rod body deforms after hitting the ball, the baseball rebounds, and then the inner surface of the hitting rod body contacts the outer surface of the inner sleeve, the rigidity increases to prevent the hitting rod body from continuing to deform, effectively improving the service life of the hitting rod body.

[0039] In an embodiment of the present application, the annular support 310 has a pair, and the facing ends of the annular support 310 have a limiting ring 311, and the inner sleeve 40 is sleeved between the limiting rings 311 of the pair of annular supports and is glued and connected with the inner sleeve 40.

[0040] The rear part of the handle connecting seat 320 has external threads, and the handle connecting seat is connected with the handle 20 through threads, and the front end of the hitting rod body 10 is buckled with a cover 110.

[0041] In the embodiment of the present application, in order to improve the connection stability of the handle connecting seat 320 and the hitting rod body 10, the outer surface of the handle connecting seat 320 has a glue groove or an inclined elastic piece 330. Figure 5 As shown, the use of the inclined elastic piece 330 can improve.

[0042] The production process of the multi-wall structure bat designed in the present application is as follows:

[0043] (1) The hitting rod body 10, the handle 20, the annular support 310, the inner sleeve 40 and the support rod 30 are respectively produced;

[0044] (2) The inner sleeve 40 is adhered to the outside of the pair of annular supports, the annular support 310 is sleeved into the front end of the support rod 30, and the annular support is fixed on the support rod 30;

[0045] (3) The handle 20 connecting seat surface of the rear part of the support rod 30 assembled in step (2) is glued, and then the front end of the hitting rod body is inserted until the outer periphery of the support rod end and the inner wall of the hitting rod body are fitted;

[0046] (4) The end of the support rod 30 is screwed or glued to the handle 20;

[0047] (5) The ball bat is closed as a whole by screwing the cover into the front end of the hitting rod body 10 and the rear end of the handle.

[0048] As shown in Figures 6-8 In order to better position the inner sleeve 310 on the support rod, a positioning mechanism is used in step (2), which includes a base 50, the base is fixed with a guide rail 520, the rear end of the guide rail 520 is slidingly fitted with a bracket 510 for being inserted into the rear part of the support rod, the upper part of the bracket has a tapered opening hole 511 for adapting the handle connecting seat, the guide rail is slidingly fitted with a positioning frame 530 located on the front side of the bracket, the upper part of the positioning frame has a U-shaped mouth 531, the diameter of the U-shaped mouth is consistent with the diameter of the support rod, and the lower surface of the positioning frame is fixedly connected with the guide rail through bolts.

[0049] In use, the support rod 30 is first buckled into the bracket 510 and the positioning frame 530 from above, and then the support rod 30 is moved backward so that the handle connecting seat 320 of the support rod 30 is clamped in the tapered opening hole in the rear part of the bracket, the rear part of the handle connecting seat 320 abuts against the bracket 510, at this time the positioning frame 530 has been adjusted to the preset position, but after the end of the support rod 30 is clamped in the tapered opening hole 511 of the bracket 510, the position of the front side end of the positioning frame 530 is the position of the right annular support piece.

[0050] When fixing the annular support piece 310 and the inner sleeve 40, the inside of the assembled pair of annular support pieces 310 and the inner sleeve 40 is smeared with related glue, and the annular support piece 310 abuts against the front side end surface of the positioning frame 530 to realize positioning.

[0051] In order to facilitate the adjustment of the positions of the bracket 510 and the positioning frame 530 on the guide rail, the base has a scale, and when the bracket 510 and the positioning frame 530 are adjusted to the position, the position is fixed by using bolts.

[0052] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
