Abstract
The utility model discloses a fastening type screw, its characterized in that: including nut, screw rod and screw, the one end and the nut of screw rod carry out fixed connection, the other end and the screw of screw rod carry out fixed connection, a recess has been seted up on the top of nut, the structure of recess is cross. The utility model has the advantages of: the utility model discloses a set up the spiral shell tooth in screw rod both sides, can effectively avoid the not hard up of screw, and then played the effect of fastening.
Description
Technical field
This utility model relates to machinery spare and accessory parts field, is specifically related to a kind of fastening type screw.
Background technology
Screw one class end is sharp-pointed such as nail, little cylinder or threaded part on conical metal bar, have a trough of belt or head with recess, is used alone.
Existing a kind of trip bolt, it has the head of a nail, rivet nut, nail tip end, is provided with arcuate thread at rivet nut periphery.When using the trip bolt of this structure, driving in relatively elaborate, the head of a nail is easily deformed, and fastening effect is not good.
Utility model content
The purpose of this utility model is in that for the deficiencies in the prior art, and a kind of fastening effect of existing offer is good, can only screw the fastening type screw that can not unscrew.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is: a kind of fastening type screw, its innovative point is in that: including nut, screw rod and screw, one end of described screw rod and nut are fixedly connected, and the other end of described screw rod and screw are fixedly connected；The top of described nut offers a groove, and the structure of described groove is cross.
Further, the both sides of described screw rod are provided with spiral shell tooth, and described spiral shell tooth is evenly distributed along screw rod vertical direction, and the structure of described spiral shell tooth is cone, and the cone height of described cone spiral shell tooth is 1-2mm.
Further, the structure of described screw is semiellipsoid, and the surface of described semiellipsoid screw uniformly offers several screw threads, and described each screw thread is evenly distributed, and described flight pitch is 0.1-0.3mm.
The beneficial effects of the utility model are as follows: this utility model is by being provided with spiral shell tooth in screw rod both sides, it is possible to be prevented effectively from loosening of screw, and then serve the effect of fastening.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.
Being illustrated in figure 1 structural representation of the present utility model, a kind of fastening type screw, including nut 1, screw rod 3 and screw 4, one end of screw rod 3 and nut 1 are fixedly connected, and the other end of screw rod 3 and screw 4 are fixedly connected；The top of nut 1 offers a groove 5, and the structure of groove 5 is cross.
The both sides of screw rod 3 are provided with spiral shell tooth 2, spiral shell tooth 2 is evenly distributed along screw rod 3 vertical direction, the structure of spiral shell tooth 2 is cone, the cone height of cone spiral shell tooth 2 is 1-2mm, this utility model is by being provided with spiral shell tooth 2 in screw rod 3 both sides, loosening of screw can be prevented effectively from, and then serve the effect of fastening.The structure of screw 4 is semiellipsoid, and the surface of semiellipsoid screw 4 uniformly offers several screw threads, and each screw thread is evenly distributed, and flight pitch is 0.1-0.3mm.
Above-described embodiment is preferred embodiment of the present utility model; it it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, be regarded as falling within the scope of the rights protection of this utility model patent.
