Abstract
The invention discloses a special-shaped bolt which comprises a bolt head and a screw provided with a thread, wherein the edge of the screw is in a step shape, the diameter of the screw is gradually decreased along the direction from the position close to the bolt head to the position far from the bolt head, and the number of steps of the screw is 3-5. According to the special-shaped bolt, due to the fact that the edge of the screw is in a step shape, the diameter of the screw is gradually decreased along the direction from the position close to the bolt head to the position far from the bolt head, the special-shaped bolt can serve as bolts with various types to be used, the unnecessary troubles which are caused by that bolts with a certain type are used up are avoided, and continuity of the production is increased indirectly. Meanwhile, the special-shaped bolt can be further used for connecting mechanical parts of which locating holes are different in size, and stability of mechanical equipment can be increased.
Description
Technical field
The present invention relates to a kind of special shaped screw bolt, particularly a kind of energy uses and can be used for connecting the special shaped screw bolt of positioning hole mechanical parts not of uniform size when the bolt of Multiple Type, belongs to be fastenedly connected the part technical field.
Background technique
Bolt is by bolt head and establish a threaded screw rod class fastening piece dimerous, is used for being fastenedly connected two with the mechanical parts of through hole.Nowadays on market, the model of bolt is various, when a kind of bolt failure of model, just must use the bolt of same model, and bolt that may this model just in time is finished, and must go out to buy, and brings unnecessary trouble, indirectly affects manufacturing efficiency.Nowadays on market, the screw rod of bolt is generally a cylindrical body and is threaded, and when the positioning hole of two mechanical parts was not of uniform size, bolt in the market just can not meet the demands.Therefore, need a kind of new technological scheme to solve the problems referred to above.
Summary of the invention
Technical problem for above-mentioned existence the objective of the invention is: proposed a kind of energy and used and can be used for connecting the special shaped screw bolt of positioning hole mechanical parts not of uniform size when the bolt of Multiple Type.
Technical solution of the present invention is achieved in that a kind of special shaped screw bolt, comprises bolt head and establishes threaded screw rod, and the edge of described screw rod is step-like; The diameter of described screw rod is from diminishing gradually near bolt head to the direction away from bolt head.
Preferably, stratum's number of described screw rod is 3～5 rank.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Special shaped screw bolt of the present invention, because the edge of screw rod is step-like, the diameter of screw rod is from diminishing gradually near bolt head to the direction away from bolt head, can use when the bolt of Multiple Type, avoid bolt because of certain model just in time to be finished and brought unnecessary trouble, indirectly increased the continuity of producing; Special shaped screw bolt of the present invention can also be used for connecting positioning hole mechanical parts not of uniform size simultaneously, has increased the stability of machinery.
Description of drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the stereogram of special shaped screw bolt of the present invention;
Wherein: 1, bolt head; 2, screw rod.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of special shaped screw bolt as shown in Figure 1 comprises bolt head 1 and establishes threaded screw rod 2, and the edge of described screw rod 2 is step-like; The diameter of described screw rod 2 is from diminishing gradually near bolt head 1 to the direction away from bolt head 1; Stratum's number of described screw rod 1 is 3～5 rank.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Special shaped screw bolt of the present invention, because the edge of screw rod is step-like, the diameter of screw rod is from diminishing gradually near bolt head to the direction away from bolt head, can use when the bolt of Multiple Type, avoid bolt because of certain model just in time to be finished and brought unnecessary trouble, indirectly increased the continuity of producing; Special shaped screw bolt of the present invention can also be used for connecting positioning hole mechanical parts not of uniform size simultaneously, has increased the stability of machinery.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow person skilled in the art scholar can understand content of the present invention and be implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
