Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of bolt for wind-powered electricity generation main frame.
Background technique
The bolt that existing wind-powered electricity generation main frame uses is conventional stud.But, due to the long-term operation in the wild of wind-powered electricity generation main frame, can there is problems such as leaking in the gap between bolt mounted thereto and screw, if things go on like this just can give birth to harmful effect to main frame inside: such as short circuit, equipment corrosion etc., also can cause shortening of bolt life.
Model utility content
The technical problems to be solved in the utility model has gap to overcome when existing bolt is connected with the screw of wind-powered electricity generation main frame, and thus main frame is easily intake and the defect causing bolt life to shorten, and provides a kind of bolt for wind-powered electricity generation main frame.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of bolt for wind-powered electricity generation main frame, it includes: a bolt shank, one bolt head, one bolt tail, its feature is, the two ends of described bolt shank respectively with one end of described bolt head, one end of described bolt tail connects, the joint of one end of described bolt shank and described bolt head has circular arc chamfering, the joint of one end of described bolt shank and described bolt tail also has circular arc chamfering, one end of described bolt head has an annular groove, an adhesive layer is provided with in described annular groove, one elastic seal ring is embedded in described annular groove, the surface of the other end of described bolt head has bolt head thread, the outer wall of described bolt shank has a pair tapered protrusion, one elastic packing pipe box is located at the outer wall of described bolt shank, the inwall of described elastic packing pipe has the groove matched with described tapered protrusion for a pair.By arranging circular arc chamfering in joint, reduce the wearing and tearing between joint and the screw of wind-powered electricity generation main frame.
Preferably, the diameter of the outer wall of described elastic packing pipe is greater than the diameter of described bolt head.Because the diameter of the outer wall of elastic packing pipe is comparatively large, when therefore bolt is installed in screw, elastic packing pipe can compress and then can fill up the space of bolt shank and screw, prevents rainwater from flowing into wind-powered electricity generation main frame from space inner, improves the life-span of bolt.
Preferably, described bolt tail is hexahedron structure, and the outer surface of the other end of described bolt tail has a nonskid coating.
Preferably, the outer wall of described bolt tail has screw thread.Screw thread on bolt tail may be used for when screw is darker, by the screw thread of the screw thread on bolt tail and bolt head, and the effect of common fixing bolt.
Preferably, described bolt shank, described bolt head, described bolt tail are one of the forming.By adopting integrally formed structure, improve the working life of bolt.
Preferably, described elastic packing pipe is rubber pipe.
Positive progressive effect of the present utility model is: prevent rainwater from entering wind-powered electricity generation main frame inner to its generation harmful effect, improve the working life of wind-powered electricity generation main frame, reduce entreprise cost.

Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment
Understood incorporated by reference to Fig. 1, a kind of bolt 1 for wind-powered electricity generation main frame, it includes: bolt shank 2, bolt head 4, bolt tail 3.One end of bolt shank 2 is fixedly connected with one end of bolt head 4, and the other end of bolt shank 2 is connected with one end of bolt tail 3.Because the diameter of bolt head 4, bolt tail 3 is not identical with the diameter of bolt shank 2, when the bolt 1 for wind-powered electricity generation main frame is used in wind-powered electricity generation main frame, if bolt head 4 does not process with the joint of bolt shank 2, then joint is level and smooth not, may produce friction with wind-powered electricity generation main frame inside and cause loss, therefore bolt shank 2 has circular arc chamfering with the joint of bolt head 4.In like manner, bolt tail 3 also has circular arc chamfering with the joint of bolt shank 2.The surface of the other end of bolt head 4 has the bolt head thread 5 of the screw bolt 1 being used for wind-powered electricity generation main frame being fixed on wind-powered electricity generation main frame inside.Bolt shank 2, bolt head 4, bolt tail 3 can be one of the forming.Bolt 1 for wind-powered electricity generation main frame should adopt stainless steel.
Understood incorporated by reference to Fig. 1, the sheathed elastic packing pipe 6 of outer wall of bolt shank 2 can be rubber pipe.The outer wall of bolt shank 2 has a pair tapered protrusion 10, and the inwall of elastic packing pipe 6 has the groove matched with tapered protrusion 10 for a pair.The effect of elastic packing pipe 6 is: when the bolt 1 for wind-powered electricity generation main frame is fixed on screw inside time, and elastic packing pipe 6 is for filling up the space between bolt shank 2 and screw, and therefore the diameter of the outer wall of elastic packing pipe 6 should be greater than the diameter of bolt head 4.Bolt tail 3 is hexahedron structure, and the outer surface of the other end of bolt tail 3 has a nonskid coating 7.Adopt hexahedron structure or nonskid coating to be all in order to when the bolt 1 being used for wind-powered electricity generation main frame is screwed into screw inside, avoid spanner to skid.
Understood incorporated by reference to Fig. 1, in order to better prevent rainwater etc. from for entering wind-powered electricity generation main frame between the bolt 1 of wind-powered electricity generation main frame and the space of screw, one end of bolt head 4 is provided with annular groove 9, and elastic seal ring 8 is embedded in annular groove 9.In order to better make elastic seal ring 8 be fixed in annular groove 9, an adhesive layer can be set in annular groove 9, for the elastic seal ring 8 that bonds.
Understood incorporated by reference to Fig. 1, in order to the bolt 1 being used in wind-powered electricity generation main frame is better fastened on the screw of wind-powered electricity generation main frame, the outer wall of bolt tail 3 can have screw thread, like this when screw is long time, screw thread on bolt tail 3 also can play the effect be connected with screw, guarantees that the bolt 1 for wind-powered electricity generation main frame has higher stability in screw.Due to bolt head 4, bolt tail 3 all having screw thread, the two ends therefore for the bolt 1 of wind-powered electricity generation main frame have all been fastened in the screw of wind-powered electricity generation main frame.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these mode of executions, but these change and amendment all falls into protection domain of the present utility model.
