Abstract
The utility model discloses a kind of light-duty intensity adjustable bolt, comprise barrel, spiral shell head, first strengthens cylinder and the second reinforcement cylinder, described barrel cylindrically, barrel outer surface is provided with screw thread, is provided with the first reinforcement cylinder and second and strengthens cylinder inside barrel, and it is rounded respectively that cylinder cross section strengthened by described first reinforcement cylinder and second, barrel is fixedly connected with spiral shell head, described spiral shell head is provided with pit, and described spiral shell head cross section is Hexagon, and the described first wall thickness strengthening cylinder and the second reinforcement cylinder is 1 ~ 3mm.The utility model can need according to intensity the bolt selecting varying strength, and bolt outside dimensions specification is consistent, decreases number of tools, device assembles efficiency can be improved, cut the waste, simultaneously bolt strong adaptability, applying flexible, can reduce the quality of equipment simultaneously.
Description
[technical field]
The utility model relates to the technical field of fastening piece, particularly a kind of technical field of light-duty intensity adjustable bolt.
[background technique]
Screw thread, the nuts and bolt of the different company's production of 18th century are not sought unity of standard, and therefore market are flooded with the screw thread of a large amount of different size, bring many troubles to machine-building business.Until 1841, Joseph's Whitworth successfully finds solution.Bolt is the shaft-like object of taking the lead of attached threaded cylinder, and the screwed cylinder in one end part is called stud, for nut screw connection, the other end is head, is called bolt head.Bolt is made of metal usually, and the bolt used at the special occasions such as electrical insulation or corrosion protection also has various non-metallic material.There is hexagon head, round end, square spigot, countersunk head etc.Wherein hexagon head is the most frequently used.General countersunk head is used in and requires to connect the smooth place not having projection, rear surface, because countersunk head may be screwed in part.Round end also can be screwed in part.The screwing force of square toes can more greatly, but size is very large.Some bolts do not have the polished rod of screw thread to run business into particular one, and are eel-like figure bolt.This bolt is conducive to the connection by variable force.Steel structure has special high-strength bolt, head can do bigger, and size also changes.
The application of current bolt widely, new purposes is also in continuous appearance, present building field, field of constructional ornament and stage are built all to be needed to use bolt, kind and the model of bolt are a lot, in order to meet different strength demands, a set of equipment often needs the bolt of plurality of specifications, reduce the efficiency of device assembles, the cost that the bolt increased is bought, can cause certain waste, a kind of bolt that can need adjustment according to intensity of market demand, outside dimensions is unified simultaneously, decrease number of tools, convenient installation.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of light-duty intensity adjustable bolt is proposed, the bolt selecting varying strength can be needed according to intensity, bolt outside dimensions specification is consistent, decreases number of tools, can improve device assembles efficiency, cut the waste, bolt strong adaptability simultaneously, applying flexible, can reduce the quality of equipment simultaneously.
For achieving the above object, the utility model proposes a kind of light-duty intensity adjustable bolt, comprise barrel, spiral shell head, first strengthens cylinder and the second reinforcement cylinder, described barrel cylindrically, barrel outer surface is provided with screw thread, be provided with the first reinforcement cylinder and second inside barrel and strengthen cylinder, it is rounded respectively that cylinder cross section strengthened by described first reinforcement cylinder and second, barrel is fixedly connected with spiral shell head, described spiral shell head is provided with pit, described spiral shell head cross section is Hexagon, and the described first wall thickness strengthening cylinder and the second reinforcement cylinder is 1 ~ 3mm.。
As preferably, the length of described barrel is 10 ~ 100mm.
As preferably, described second strengthens cylinder is arranged in the first reinforcement cylinder, and first strengthens cylinder and the second wall thickness strengthening cylinder is 2mm.
As preferably, the cross section of described pit is Hexagon.
The beneficial effects of the utility model: the utility model is by strengthening cylinder be applied in bolt member by barrel, the first reinforcement cylinder and second, the bolt selecting varying strength can be needed according to intensity, bolt outside dimensions specification is consistent, decreases number of tools, can improve device assembles efficiency, cut the waste, bolt strong adaptability simultaneously, applying flexible, is applied in aircraft devices, the quality of equipment can be reduced, improve the flying distance of aircraft.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.

[embodiment]
Consult Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of light-duty intensity adjustable bolt of the utility model, comprise barrel 2, cylinder 5 strengthened by spiral shell head 3, first reinforcement cylinder 4 and second, described barrel 2 cylindrically, barrel 2 outer surface is provided with screw thread 21, be provided with the first reinforcement cylinder 4 and second inside barrel 2 and strengthen cylinder 5, described first reinforcement cylinder 4 and the second reinforcement cylinder 5 cross section are distinguished rounded, barrel 2 is fixedly connected with spiral shell head 3, described spiral shell head 3 is provided with pit 31, described spiral shell head 3 cross section is Hexagon, and the described first wall thickness strengthening cylinder 4 and the second reinforcement cylinder 5 is 1 ~ 3mm.The length of described barrel 2 is 10 ~ 100mm.Described second strengthens cylinder 5 is arranged in the first reinforcement cylinder 4, and the first wall thickness strengthening cylinder 4 and the second reinforcement cylinder 5 is 2mm.The cross section of described pit 31 is Hexagon.
Utility model works process:
A kind of light-duty intensity adjustable bolt of the utility model in the course of the work, according to the constant intensity needs of equipment, is selected the reinforcement cylinder adding different number, is inserted by reinforcement cylinder from the opening of barrel 2.
A kind of light-duty intensity adjustable bolt of the utility model, by being applied in bolt member by barrel 2, first reinforcement cylinder 4 and the second reinforcement cylinder 5, can need according to intensity the bolt selecting varying strength, bolt outside dimensions specification is consistent, decrease number of tools, device assembles efficiency can be improved, cut the waste, simultaneously bolt strong adaptability, applying flexible, be applied in aircraft devices, the quality of equipment can be reduced, improve the flying distance of aircraft.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
