Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, the utility model embodiment provides a kind of sheet metal part fixed structure 1, for sheet metal part 2 is fixed on to the structural member 3 with through hole 31, sheet metal part fixed structure 1 comprises having the riveting post 11 of screw thread 111 and for coordinate structural member 3 to be compressed to the link 12 being fixed on sheet metal part 2 with riveting post 11, adopt punch press equal pressure equipment by riveting post 11 the direction riveting along sheet metal part 2 to structural member 3 to sheet metal part 2, riveting post 11 comprises Embedded Division 112 and is located at the joint 113 on Embedded Division 112, after riveting post 11 rivetings are on sheet metal part 2, Embedded Division 112 has part-structure and embeds in sheet metal part 2, screw thread 111 is opened on joint 113, form and be threaded with link 12.In the present embodiment, structural member 12 is located to the top of sheet metal part 2, riveting post 11 enters along lower surface 21 rivetings of sheet metal part 2, and Embedded Division 112 has part-structure and is embedded in sheet metal part 2, its structure of protruding sheet metal part 2 lower surfaces 21 is less, the lower surface 21 that can guarantee sheet metal part 2 is more smooth, and the mode of this riveting of while can not form the stress of sheet metal part 2 and concentrate, and avoids causing the torsional deformation of sheet metal part 2.Usually, riveting post 11 is column structure, can offer as required the area that is threaded between larger joint 113 and link 12, thereby can guarantee the stability that is threaded between link 12 and riveting post 11.
Further, riveting post 11 is provided with material extrusion groove 114, by riveting post 11 rivetings to sheet metal part 2, have part sheet metal part 2 be arranged in material extrusion groove 114, material extrusion groove 114 is located on the joint of joint and Embedded Division.By riveting post 11 rivetings to sheet metal part 2, joint 113 is through sheet metal part 2, and the part-structure of Embedded Division 112 and material extrusion groove 114 are all positioned at sheet metal part 2, and having part sheet metal part 2 is arranged in material extrusion groove 114, this can strengthen the stability being connected between riveting post 11 and sheet metal part 2, guarantees that the riveting post 11 after riveting there will not be loosening or departs from sheet metal part 2.
Referring to Fig. 1 and Fig. 2, joint 113 has the locating column 115 that can stretch in through hole 31 further, and locating column 115 is located at joint 113 away from one end of Embedded Division 112, and screw thread 111 is opened on locating column 115.By riveting post 11 rivetings to sheet metal part 2, then when structural member 3 is placed on sheet metal part 2, locating column 115 stretches in through hole 31, the effect that this can play location prevents that structural member 3 is offset, and then has also facilitated riveting post 11 and link 12 to be connected.
Referring to Fig. 1 and Fig. 5, for the screw thread 111 on riveting post 11, can be divided into two kinds of internal thread 111a and outside thread (not shown)s.When the screw thread 111 on riveting post 11 is internal thread 111a, specifically on the joint 113 of riveting post 11, be provided with groove 116, on groove 116 inwalls, offer internal thread 111a, link 12 is screw 12a, screw 12a stretches into along the through hole 31 of structural member 3 in the groove 116 of riveting post 11 and is connected until screw 12a compresses structural member 3 with internal thread 111a, thereby sheet metal part 2 and structural member 3 are connected and fixed.Screw thread on riveting post 11 is outside thread, specifically joint 113 outer surfaces of riveting post 11 are provided with outside thread, link 12 is for being sheathed on the nut (not shown) of joint 113 outer surfaces, riveting post 11 rivetings to the rear joint 113 of sheet metal part 2 stretches in through hole 31, the outside thread of nut and riveting post 11 is connected until nut compresses structural member 3, thereby sheet metal part 2 and structural member 3 are connected and fixed.
Particularly, the first hole 311 and the second hole 312 that the through hole 31 on structural member 3 is communicated with, link 12 is embedded in the first hole 311 and the second hole 312, makes link 12 there is no projective structure part 3 surfaces, can not impact structural member 3 surfaces.The aperture in direction first hole 311 of through hole 31 along sheet metal part 2 to structural member 3 is less than the aperture in the second hole 312, thereby the joint at the first hole 311 inwalls and the second hole 312 inwalls forms ladder surface 313, when riveting post 11 is provided with internal thread 111a, riveting post 11 stretches into the first hole 311 of through hole 31, link 12 is screw 12a, its first hole 311 of also stretching into through hole 31 is connected with riveting post 11, and the nut of screw 12a compresses the ladder surface 313 of through hole 31; And when riveting post 11 is provided with outside thread, riveting post 11 stretches into the second hole 312 of through hole 31, link 12 is made as nut, and its second hole 312 that is positioned at through hole 31 is connected with riveting post 11, and nut compresses the ladder surface 313 of through hole 31.
Referring to Fig. 3-Fig. 5, the utility model embodiment also provides a kind of air conditioner, comprise outer box plate 2a and spiral case 3a, outer box plate 2a is made by panel beating, and spiral case 3a is foamed material, between outer box plate 2a and spiral case 3a, by many groups of above-mentioned sheet metal part fixed structures 1, is connected and fixed, riveting post 11 rivetings are to outer box plate 2a, spiral case 3a is provided with through hole 31, and link 12 is stretched into the riveting post 11 after riveting and is threaded by through hole 31, thereby outer box plate 2a and spiral case 3a are connected and fixed.In the present embodiment, between outer box plate 2a and spiral case 3a, by sheet metal part fixed structure 1, be connected, can there is not the concentrated situation of stress in outer box plate 2a, it is difficult to occur torsional deformation, has both ensured the quality of products and has required also can not affect its outward appearance, again because the stability being threaded between riveting post 11 and link 12, even air conditioner long-term work, be threaded and also can not become flexible because of the vibrations of air conditioner self, and then guarantee that spiral case 3a can not become flexible, and eliminates quality hidden danger.
The foregoing is only the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
