Abstract
The utility model discloses a combined type bolt, which comprises a bolt (1) for a reamed hole and a connecting rod (2); wherein, an end surface of one end of the connecting rod (2) is fixed with a head part (3) which can be located by spanners or a screwdriver and then cause the connecting rod (2) to rotate; the inside of the connecting rod (2) is provided with an axial screwed hole (4); the bolt (1) for the reamed hole is screwed inside the axial screwed hole (4); the head part (3) which can be located by spanners or the screwdriver and then cause the connecting rod to rotate is provided with a horizontal linear groove or a cross groove. The combined type bolt has the advantages that: the performance of fixed connection of rivets is obtained, and the bolt can be disassembled from the connecting piece later.
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, to carry out punching press by special punching equipment again, thereby two connected pieces are linked together.Though use rivet to connect firmly, because rivet is rivetted through one end after the punching press, therefore connected in the future two connected pieces can not be dismantled again, and this has brought inconvenience for the running repairs of later connected piece.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of and not only has the performance that rivet is connected firmly, and the combined bolt that in the future can dismantle from connected piece.
Technical solution of the present utility model is, a kind of combined bolt with following structure is provided, and it comprises that an articulation hole is with bolt and a connecting rod; Be fixed with the head of an available spanner or screw-driver location and then rotatable connecting rod on the end face of described connecting rod one end; Be provided with the axial screw thread hole in the described connecting rod; Described articulation hole screws in described axial screw thread hole with bolt.
After adopting above structure, compared with prior art, the utlity model has following advantage: articulation hole not only makes the utility model can have the performance that rivet is connected firmly with being used of bolt and connecting rod, and because the articulation hole bolt is to screw in the tapped hole of connecting rod, therefore the utility model can screw out the articulation hole bolt in tapped hole, make to have the utlity model has dismountable function, for the maintenance of connected piece has in the future brought convenience.
Have straight groove or cross recess on the head of above-mentioned available spanner or screw-driver location and then rotatable connecting rod.
Description of drawings:
Fig. 1 is a broken section structural representation of the present utility model.
Left TV structure schematic representation when having straight groove on the head of Fig. 2 for available spanner among Fig. 1 or screw-driver location and then rotatable connecting rod.
Left TV structure schematic representation when having cross recess on the head of Fig. 3 for available spanner among Fig. 1 or screw-driver location and then rotatable connecting rod.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, the utility model combined bolt comprises an articulation hole bolt 1 and a connecting rod 2; The end face of described connecting rod 2 one ends is fixed with the head 3 of an available spanner or screw-driver location and then rotatable connecting rod 2; Be provided with axial screw thread hole 4 in the described connecting rod 2; Described articulation hole screws in described axial screw thread hole 4 with bolt 1.Articulation hole is a current techique term with bolt 1 in the utility model, and its bolt head 7 can be outer-hexagonal shape, also can open an interior hexagonal counterbore or straight groove or cross recess etc. on bolt head 7.The utility model is preferably and opens straight groove or cross recess on bolt head 7.In addition, the length of tapped hole described in the utility model 4 can equal the length of articulation hole with the threaded stem 8 of bolt 1, also can be greater than the length of articulation hole with the threaded stem 8 of bolt 1.
As shown in Figures 2 and 3, can have straight groove 5 or cross recess 6 on the head 3 of location of available spanner or screw-driver described in the utility model and then rotatable connecting rod 2.
Certainly; the head 3 of location of available spanner or screw-driver described in the utility model and then rotatable connecting rod 2 is not limited to open in the above straight groove 5 or cross recess 6; it also can adopt outer-hexagonal shape head or open an interior hexagonal counterbore in the above, and these variations all fall into protection domain of the present utility model.
