Abstract
The utility model discloses a combination typed screw, including a screw (1) and a connecting rod (2); wherein, one end of the connecting rod (2) is fixedly provided with a head (3) which can be positioned by a wrench or a screwdriver further rotates the connecting rod (2); the connecting rod (2) is internally provided with an axial screw thread hole (4); the screw (1) is revolved in the axial screw thread hole (4); the head (3) is provided with a straight slot (9)and a cruciform slot. The combination typed screw has the advantages that the screw not only has the performance of firmly connecting with a rivet, but also can be dismounted from a connecting piece.
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 type screw.
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 type screw that in the future can dismantle from connected piece.
Technical solution of the present utility model is, a kind of combined type screw with following structure is provided, and it comprises a screw and a connecting rod; One end of described connecting rod is fixed with the head of an available spanner or screw-driver location and then rotatable connecting rod, is provided with the axial screw thread hole in the described connecting rod; Described screw screws in described axial screw thread hole.
After adopting above structure, compared with prior art, the utlity model has following advantage: being used of screw and connecting rod not only makes the utility model can have the performance that rivet is connected firmly, and because screw is to screw in the tapped hole of connecting rod, therefore the utility model can screw out screw in tapped hole, realized the detachability of connected piece, in the future maintenance has brought convenience.
Can 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 Fig. 2 has straight groove for the head of available spanner in the utility model or screw-driver location and then rotatable connecting rod.
Left TV structure schematic representation when Fig. 3 has cross recess for the head of available spanner in the utility model 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 type screw comprises a screw 1 and a connecting rod 2; One end of described connecting rod 2 is fixed with the head 3 of an available spanner or screw-driver location and then rotatable connecting rod 2, is provided with axial screw thread hole 4 in the described connecting rod 2; Described screw 1 screws in described axial screw thread hole 4.Screw 1 is a screw conventional on the industry in the utility model, and it can be outer-hexagonal shape screw or hexagon socket head cap screw etc.In the utility model, the length of tapped hole 4 can equal the length of the threaded stem 7 of screw 1, also can be greater than the length of threaded stem 7.
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.
Certainly; the head 3 of location of available spanner or screw-driver described in the utility model and then rotatable connecting rod is not limited to out straight groove 5 or cross recess 6; hexagonal counterbore in it also can be provided with in head 3 also can adopt outer-hexagonal shape, and these variations all fall into protection domain of the present utility model.
