The specific embodiment
For the technical scheme that those skilled in the art can understand the utility model better and provided, set forth below in conjunction with specific embodiment.
See also Fig. 1-Fig. 7, Fig. 1 is the structural representation that accommodation rail is connected with railing post in the utility model; Fig. 2 is the structural representation of railing combined type fastening connection piece in the utility model; Fig. 3 is the cross-sectional structure sketch map of railing post in the utility model; Fig. 4 is the cross-sectional structure sketch map of the first dislocation part in the utility model; Fig. 5 is the cross-sectional structure sketch map of the second dislocation part in the utility model; Fig. 6 is the structural representation of cross bar in the utility model; Fig. 7 is the cross section structure sketch map of accommodation rail in the utility model.
The railing combined type fastening connection piece that the utility model provides; Comprise lead screw 2, the first dislocation part 7 and the second dislocation part 6; The first dislocation part, 7 middle parts are provided with screw hole 71; The middle part of the second dislocation part 6 is provided with dislocation hole 61, the first dislocation parts 7 and the second dislocation part 6 bigger slightly than screw hole 71 and is respectively arranged with the inclined-plane, and the inclined-plane and the angle of inclination between the horizontal plane of the first dislocation part 7 and the second dislocation part 6 are 60 °; Railing post S2 is provided with circular connecting hole 21; The first dislocation part 7 is identical with the shape of connecting hole 21 with the cross sectional shape of the second dislocation part 6; Be socketed in the connecting hole 21 after the inclined-plane butt joint of the inclined-plane of the first dislocation part 7 and the second dislocation part 6, the dislocation hole 61 that lead screw 2 is passed the second dislocation part 6 is connected with the screw hole 71 of the first dislocation part 7.
Need to prove that the first dislocation part 7 is identical with the shape of connecting hole 21 with the cross sectional shape of the second dislocation part 6, because circular connecting hole 21 is made up of two arc joint faces 23.Therefore, exactly, the cross sectional shape that the first dislocation part 7 and second misplaces part 6 be with the 23 virtual extensions of two arc joint faces form round-shaped identical.Railing post is hollow column, and connecting hole 21 is made up of two joint faces 23, and joint face 23 is structure as a whole with the inwall of railing post S2, can save materials, practices thrift cost.
