Abstract
The utility model discloses a combined bolt, which comprises two bolts (1), two washers (2) and a positioning guiding pole (3), wherein, the two washers (2) are respectively clamped on the two head faces of the positioning guiding pole (3); at least two grooves (32) are arranged in the head faces of the positioning guiding pole (3); at least two lug bosses (21) are arranged on the inner circles of the two washers (2), wherein, the lug bosses (21) can be clamped on the grooves (32); the two bolts (1) are respectively screwed up inside the axial threaded holes (31) at the two ends of the positioning guiding pole (3). The combined bolt has the advantages of convenient and flexible disassembly and maintenance, and performs an effective function of firm rivet connection.
Description
Technical field:
The utility model relates to a kind of fastening piece that is used for mechanical connection, specifically is a kind of combined bolt.
Background technique:
In mechanical industry, the usage of rivet is after the end with rivet passes the unthreaded hole of two connected pieces, carries out punching press by special punching equipment again or presses with the hammer hammer, thereby two connected pieces are linked together.Though use rivet to connect firmly, but because rivet presses back one end to be rivetted through punching press or hammer, therefore connected two connected pieces can not dismantled in the future again, this has brought inconvenience for the daily dismounting and the maintenance of later connected piece, also just because of the inconvenience of rivet dismounting and maintenance, thereby make it be not easy in some particular places such as open-air mechanical work environment, use, limited the scope of its use.
The model utility content:
The technical problems to be solved in the utility model is a kind of dismounting, easy to maintenance, flexible, applied widely to be provided, and can effectively to bring into play the combined bolt of the firm interconnect function of rivet.
Technical solution of the present utility model is that a kind of combined bolt with following structure is provided: it comprises screw and positioning and guiding bar; Described screw is two; Described two screws screw respectively in the axial screw thread hole at positioning and guiding bar two ends.
After adopting above structure, compared with prior art, the utlity model has following advantage: because two screws in the utility model all are to screw in the tapped hole at positioning and guiding bar two ends, therefore not only dismounting of the utility model combined bolt, easy to maintenance, flexible, and because dismounting, easy to maintenance, flexible, thereby make the utility model be adapted at the use of a lot of places; And thereby the utility model has been brought into play the effect that rivet firmly is connected by the screw and the cooperation of positioning and guiding bar.
As a kind of improvement of the present utility model, be connected with packing ring respectively on the both ends of the surface of the positioning and guiding bar between described screw and the axial screw thread hole.Being used of packing ring and screw and positioning and guiding bar can make the utility model further give full play to the characteristic that is connected firmly that rivet has.
As another kind of improvement the of the present utility model, the axial screw thread hole at described positioning and guiding bar two ends communicates.With the axial screw thread hole connection at positioning and guiding bar two ends is only an axial screw thread hole to be set in the positioning and guiding bar can make the use of two screws in the utility model different in size, and can determine the length of two screws according to actual needs respectively.

Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, the utility model combined bolt comprises two screws 1, two packing rings 2 and positioning and guiding bars 3.Described two packing rings 2 are connected to respectively on the both ends of the surface of positioning and guiding bar 3, in this specific embodiment, it is following concrete structure that described packing ring 2 is connected to what adopt on the both ends of the surface of positioning and guiding bar 3: be respectively equipped with two grooves 32 on the both ends of the surface of described positioning and guiding bar 3; Be respectively equipped with two projections 21 that can be stuck on the groove 32 on the interior circle of described two packing rings 2.Certainly, the quantity of the utility model further groove 32 and projection 21 also can be three, four or five.Described two screws 1 screw respectively in the axial screw thread hole 31 at positioning and guiding bar 3 two ends.In this specific embodiment, the axial screw thread hole 31 at described positioning and guiding bar 3 two ends communicates, and in other words, the utility model has only an axial screw thread hole.In the utility model, described screw 1 can be a word button-headed screw, cross button-headed screw, interior hexagonal button-headed screw, a letter disk head screw, cross pan head screw, interior hexagonal pan head screw, outer-hexagonal screw, a word outer-hexagonal screw, cross outer-hexagonal screw and socket head screw.In this specific embodiment, what described screw 1 adopted is the outer-hexagonal screw.
Packing ring described in the utility model 2 is connected to structure on the both ends of the surface of positioning and guiding bar 3 and is not limited to the projection 21 that can be stuck on the groove 32 is set being provided with on positioning and guiding bar 3 both ends of the surface on groove 32 and the interior circle at packing ring 2; it also can be provided with projection 21 on positioning and guiding bar 3 both ends of the surface; and groove 32 is set on the interior circle of packing ring 2, above-mentioned variation falls into protection domain of the present utility model equally.
