Abstract
The invention discloses a combination bolt, comprising two screws (1), two washers (2) and a positioning guide rod (3); the two washers (2) are respectively clamped on the two end surfaces of the positioning guide rod (3), namely, the two end surfaces of the positioning guide rod (3) are respectively provided with two or more than two concave troughs (32); the inner circles of the two washers (2) are respectively provided with two or more than two convex blocks (21) which can be clamped on the concave troughs (32); the two screws (1) are respectively screwed in the axial thread holes (31) at the two ends of the positioning guide rod (3). The combination bolt has the advantages of convenient and flexible disassembly/assembly and maintenance, wide applicable range, and effectively playing the firm connection function of a rivet.
Description
Technical field:
The present invention 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.
Summary of the invention:
The technical problem to be solved in the present invention 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 invention 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 present invention has the following advantages: because two screws among the present invention all are to screw in the tapped hole at positioning and guiding bar two ends, therefore not only dismounting of combined bolt of the present invention, easy to maintenance, flexible, and because dismounting, easy to maintenance, flexible, thereby make the present invention be adapted at the use of a lot of places; And thereby the present invention has 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 invention, 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 present invention further give full play to the characteristic that is connected firmly that rivet has.
As another kind of improvement the of the present invention, 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 among the present invention different in size, and can determine the length of two screws according to actual needs respectively.

Specific embodiment:
The invention will be further described 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, combined bolt of the present invention 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 further groove 32 of the present invention 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 present invention has only an axial screw thread hole.In the present invention, 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 present invention 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 scope of the present invention equally.
