Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate specific embodiment of the utility model.
Such as Fig. 3 and combine shown in Fig. 4, the utility model discloses a kind of plumb joint soldered into position structure, this location structure is arranged at the first structural member 21 and the junction of the second structural member 22 that need to be located by connecting.This location structure comprises the connecting portion 23 being mechanically connected the first structural member 21.
Such as Fig. 4 and combine shown in Fig. 5, being provided with accommodation space 231 in connecting portion 23, this accommodation space 231 is provided with opening 232, and the second structural member 22 is set in this accommodation space 231 by opening 232.
The position that the accommodation space 231 of connecting portion 23 contacts with the second structural member 22, withheld in accommodation space 231 by the outside of connecting portion 23, inwall at accommodation space 231 forms fastened structure, this fastened structure is protruding towards the second structural member 22, thus be in close contact with the outer wall of the second structural member 22 and the outer wall of the second structural member 22 is extruded, the pressure towards the second structural member 22 is applied to the outer wall of the second structural member 22 by fastened structure, the position making the outer wall of the second structural member 22 contact with fastened structure is formed and is applied deformation produced by pressure by fastened structure, realize the second structural member 22 and connecting portion 23 interference fit, parts are made no longer to be mutually shifted, the second structural member 22 and the first structural member 21 is made to realize location.
As shown in Figure 6, fastened structure comprises some point-like bulge-structures 234 and some pitting structures 222 of reply.Point-like bulge-structure 234 is arranged at the inwall of accommodation space 231, protruding to the second structural member 22 outer wall and apply pressure；The position of the outer wall correspondence point-like bulge-structure 234 of the second structural member 22, due to stress and deformation, forms pitting structure 222.
The internal diameter of the external diameter of point-like bulge-structure 234 and pitting structure 222 is in the range of 1 to 2 millimeter, and in the present embodiment, the external diameter of point-like bulge-structure 234 is set to 1.5 millimeters with the internal diameter of pitting structure 222, i.e. radius is 0.75 millimeter.
As Fig. 5 combines shown in Fig. 6, for the embodiment of a kind of plumb joint soldered into position structure.Wherein, the first structural member 21 is pipe fitting joint, and the second structural member 22 is pipe fitting.First structural member 21 is connected by connecting portion 23 is fixing with the second structural member 22.
Accommodation space 231 it is provided with in connecting portion 23, accommodation space 231 is provided with at least two opening, accommodation space 231 is socketed the second structural member 22 by an opening and connects the mouth of pipe of the second structural member 22, the accommodation space 231 pipe connector by another open communication the first structural member 21.
Owing to the second structural member 22 is pipe fitting, accommodation space 231 is loop configuration, and the point-like bulge-structure 234 of fastened structure is annularly distributed in the inwall of accommodation space 231, and the adjacent angle between point-like bulge-structure 234 is 45 degree.Accordingly, forming the pitting structure 222 of annular spread at the second structural member 22 outer wall, the adjacent angle between pitting structure 222 is 45 degree.
Further, an annular spread shape bulge-structure 234 of punctuating on accommodation space 231 inwall is a point-like projection circle.For improving fixed effect, several point-like projection circles of formation can be withheld on accommodation space 231 inwall, and form some pitting circles at the second structural member 22 outer wall accordingly.
Further, accommodation space 231 is socketed the opening part of the second structural member 22 and is additionally provided with the sealing structure that the mouth of pipe making the second structural member 22 is tightly connected with accommodation space 231, and this sealing structure can be formed by welding.
