Detailed description of the preferred embodiment

As shown in figure 1, the utility model discloses sightseeing vehicle frame connection improves structure, including vertical frame 1, horizontal frame 2, fixed mounting has sub-piece connecting piece 3 on vertical frame 1, its afterbody and vertical frame 1 fixed connection. The first groove 302 and the second groove 303 are formed in the transverse outer surface of the sub-sheet connecting piece 3, and through holes are formed in the first groove 302 and the second groove 303. The first groove 302 and the second groove 303 have a diameter slightly larger than the nut diameter of the screw.

The top end of the transverse frame 2 is tightly sleeved with the master slice connecting piece 4, and the master slice connecting piece 4 comprises a fixed block 405, a connecting rod 406 and a sub slice limiting block 407. The transverse frame 2 is a hollow pipe, the shape of the fixing block 405 is tightly matched with the hollow part of the transverse frame 2 and fixedly sleeved in the transverse frame 2, a first fixing hole 401 and a second fixing hole 402 are arranged on the inner side wall of the connecting rod 406 corresponding to the first groove 302 and the second groove 303, and the first fixing hole 401 and the second fixing hole 402 are arranged. The inner walls of the first fixing hole 401 and the second fixing hole 402 are provided with internal threads.

The inner side surface of the sub-sheet connecting piece 3 is matched with the inner side surface shape of the mother sheet connecting piece 4, the inner side wall of the sub-sheet connecting piece 3 is tightly attached to the inner side wall of the mother sheet connecting piece 4, and the shape of the sub-sheet connecting piece 3 which is attached to the mother sheet connecting piece 4 is consistent with the shape of the transverse frame 2.

A first reinforcing block 304 in the shape of a quadrangular frustum pyramid is arranged around the through hole of the first groove 302 on the inner side surface of the sub-sheet connecting piece 3, and a quadrangular frustum pyramid groove 403 matched with the first reinforcing block is correspondingly arranged around the first fixing hole 401; a second reinforcing block 305 shaped like a cone is arranged around the through hole of the second groove 303, and a cone groove 404 is correspondingly arranged around the second fixing hole 402.

When the longitudinal frame 1 and the transverse frame 2 are assembled, the female connecting piece 4 is tightly sleeved in the hollow of the transverse frame 2 through the fixing block 405. Then the top end of the sub-piece connecting member 3 abuts against the sub-piece limiting block 407, the quadrangular frustum groove 403 is aligned with the first reinforcing block 304, the circular cone groove 404 is aligned with the second fixing hole 402, so that the first groove 302 is aligned with the first fixing hole 401, the second groove 303 is aligned with the second fixing hole 402, and the longitudinal frame 1 and the transverse frame 2 are assembled by fixing with screws. The design of the quadrangular frustum groove 403, the first reinforcing block 304, the circular cone groove 404 and the second fixing hole 402 ensures that a tiny buckling effect is realized on the longitudinal frame 1 and the transverse frame 2 in the assembling process, so that a worker can apply small force to ensure that the transverse frame 2 is not easy to fall off from the longitudinal frame 1, and the worker can conveniently twist screws. Since the diameters of the first groove 302 and the second groove 303 are slightly larger than the diameter of the nut of the screw, the nut is hidden in the sub-sheet connecting member 3 after the screw is fixed. And the shape of the sub-sheet connecting piece 3 and the mother sheet connecting piece 4 after being laminated and molded is consistent with the shape of the transverse frame 2. In conclusion, the connected frame connecting piece has no edges and corners, and can avoid the phenomenon that workers cut clothes and scratch skin in the operation process.
