Abstract
The utility model relates to a special-shaped bolt comprising a bolt head and a screw rod with screw thread, wherein the edge of the screw rod is of a shape of a step; the diameter of the screw rod is gradually reduced in the direction from the part close to the bolt head to the part far away from the bolt head; the number of the steps of the screw rod is 3-5 steps; according to the special-shaped bolt, and the edge of the screw rod is in a shape of the step, and the diameter of the screw rod is gradually reduced in the direction from the part close to the bolt head to the part far away from the bolt head, so that the special-shaped bolt can be taken as the bolts with various models, the unnecessary trouble since the bolt of certain model is just completely used can be avoided, and the production continuity is indirectly added; and the special-shaped bolt further can be used for machinery parts with different-size connecting positioning holes, so that the stability of machinery equipment can be improved.
Description
Technical field
The utility model relates to a kind of special shaped screw bolt, and particularly a kind of ability is worked as the bolt use of multiple model and can be used to connect the special shaped screw bolt of positioning hole mechanical parts not of uniform size, belongs to be fastenedly connected the part technical field.
Background technique
Bolt is used to be fastenedly connected two mechanical parts that have through hole by bolt head and the screw rod one type of fastening piece dimerous that is provided with screw thread.Nowadays the model of bolt is various on the market, when a kind of bolt failure of model, just must use the bolt of same model, and bolt that maybe this model just in time uses up, and must go out to buy, and brings unnecessary trouble, the indirect manufacturing efficiency that influences.Nowadays the screw rod of bolt is generally a cylindrical body and is threaded on the market, 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.
The model utility content
The utility model purpose is to provide a kind of ability to use and can be used to connect the special shaped screw bolt of positioning hole mechanical parts not of uniform size when the bolt of multiple model for the deficiency that overcomes existing technology.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of special shaped screw bolt, comprise bolt head and the screw rod that is provided with screw thread, and the edge of said screw rod is step-like; The diameter of said screw rod is from diminishing gradually near bolt head to the direction away from bolt head.
Preferably, stratum's number of said screw rod is 3～5 rank.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The special shaped screw bolt of the utility model; 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 model, avoid bolt because of certain model just in time to use up and brought unnecessary trouble, indirect increase the continuity of producing; The special shaped screw bolt of the utility model can also be used to connect positioning hole mechanical parts not of uniform size simultaneously, has increased the stability of machinery.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the stereogram of the special shaped screw bolt of the utility model;
Wherein: 1, bolt head; 2, screw rod.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of special shaped screw bolt of the utility model shown in accompanying drawing 1 comprises bolt head 1 and the screw rod 2 that is provided with screw thread, and the edge of said screw rod 2 is step-like; The diameter of said screw rod 2 is from diminishing gradually near bolt head 1 to the direction away from bolt head 1; Stratum's number of said screw rod 1 is 3～5 rank.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The special shaped screw bolt of the utility model; 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 model, avoid bolt because of certain model just in time to use up and brought unnecessary trouble, indirect increase the continuity of producing; The special shaped screw bolt of the utility model can also be used to connect positioning hole mechanical parts not of uniform size simultaneously, has increased the stability of machinery.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
