[0020] The following is only the preferred embodiment of the utility model, the protection scope is not only limited to this embodiment, and belongs to the protection scope of the utility model for the technical scheme under the idea of the utility model. It should be pointed out that for ordinary skilled person in the art, under the premise of not departing from the principle of the utility model, a number of improvements and refinements, these improvements and refinements should be regarded as the protection scope of the utility model.

[0021] As shown in the figure, a straight -through pipe connecting bolt structure, including bolt main body 1, bolt main body 1 top is connected with bolt head 2.

[0022] Bolt head 2 surface is equipped with buffer structure, and the buffer structure includes buffer rod 3, buffer groove 4, spring 5, support rod 6 and buffer baffle 7, and the buffer rod 3 is connected with the bolt head 2 on both sides of the bolt main body 1, the buffer groove 4 is opened on the outside of the buffer rod 3, the buffer baffle 7 is connected with the buffer groove 4 through the spring 5, one end of the support rod 6 is connected with the buffer groove 4, and the other end of the support rod 6 is located on the surface of the buffer rod 3. Anti -skid lines are opened on the outside of bolt head 2. When the straight -through pipe slides, the inner wall of the straight -through pipe hits the buffer baffle 7 and contracts the spring 5.

[0023] The bolt body 1 is threadedly connected with a nut 8 at one end away from the bolt head 2, connecting grooves 9 are formed on both sides of the nut 8, and a fixing structure is rotatably connected in the connecting grooves 9. The fixing structure comprises a rotating rod 10, a pressing rod 11 and a fixing ring 12, the rotating rod 10 is fixedly connected with both sides of the connecting grooves 9, the pressing rod 11 is rotatably connected with the rotating rod 10, and the fixing ring 12 is fixedly connected with the rotating rod 10. An adjusting groove is formed in the inner side of the fixing ring 12, a clamping plate 13 is connected in the adjusting groove through a spring 5, and guide grooves are formed in both ends of the clamping plate 13 towards the inside. After the nut 8 is threadedly connected, the pressing rod 11 is rotated from the rotating rod 10, the position of the clamping plate 13 in the fixing ring 12 is adjusted so that the fixing ring 12 is sleeved into the buffer rod 3, and the service life is improved.

[0024] Working principle: when the straight-through pipe slides, the inner wall of the straight-through pipe hits the buffer baffle 7 and the spring 5 is contracted. After the nut 8 is threadedly connected, the pressing rod 11 is rotated from the rotating rod 10, the position of the clamping plate 13 in the fixing ring 12 is adjusted so that the fixing ring 12 is sleeved into the buffer rod 3, and the service life is improved.

[0025] In summary, through the buffer baffle 7 and the spring 5, when the straight-through pipe connected by the bolt moves, the horizontal impact on the bolt body 1 is reduced, and the breakage is prevented.
