Abstract
The utility model discloses a bolt for wind power generation. The bolt comprises a bolt head and a threaded rod and is characterized in that a slender-waist polish rod is arranged between the bolt head and the threaded rod, the threaded rod is of a stepped structure, and an arc transitional structure is adopted between the upper step of the threaded rod and the lower step of the threaded rod. According to the bolt for the wind power generation, the slender-waist polish rod is arranged between the bolt head and the threaded rod, and meanwhile, the threaded rod is of a stepped structure with uneven thickness, so that the looseness of the connection positions among various parts of wind power generation equipment can be avoided under the impact of a changing force, the firmness and stability of the wind power generation equipment are effectively maintained, and the safety of the wind power generation equipment during working is ensured.
Description
Technical field
The utility model relates to a kind of bolt, particularly the wind-powered electricity generation bolt.
Background technique
Bolt is made up of bolt head and screw rod, has outside thread on the screw rod, needs to cooperate with nut, is used to be fastenedly connected two parts that have through hole, and this Connecting format is called bolt and connects, and a plurality of parts are connected in one and have just constituted machine, like wind power plant.Wind power plant in use, the connection part of its each part will bear the effect of various external force, this external force possibly be constant force, also possibly be variable force.Under the situation of variable force, if connect with the screw rod of thickness unanimity, usually can be under inotropic action and become flexible, thus cause whole wind power plant to break down.
The model utility content
The purpose of the utility model is to provide a kind of connection part of each part of wind power plant that can effectively guarantee receiving the wind-powered electricity generation bolt that does not occur loosening situation under the variable force impact for the deficiency that solves above-mentioned existing technology.
To achieve these goals, the wind-powered electricity generation bolt that the utility model designed comprises bolt head and screw rod, it is characterized in that between bolt head and screw rod, being provided with the eel-like figure polished rod, and said screw rod is a ledge structure, is the arc transition structure between screw rod is topped bar and screw rod is got out of a predicament or an embarrassing situation.
Foregoing invention is created, and makes the connection part of each part of wind power plant can avoid loosening under impacting receiving variable force.
The wind-powered electricity generation bolt that the utility model obtains; It is provided with the eel-like figure polished rod between bolt head and screw rod; Screw rod is the ledge structure that thickness differs simultaneously; Make the connection part of each part of wind power plant impact down and can avoid loosening receiving variable force, thus effectively keep wind power plant firmly with stable, guaranteed the Security when wind power plant is worked.
Description of drawings
Fig. 1 is embodiment 1 an overall structure schematic representation.
Among the figure: bolt head 1, screw rod 2, eel-like figure polished rod 3, screw rod get out of a predicament or an embarrassing situation 21, screw rod tops bar 22.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment:
Wind-powered electricity generation bolt as shown in Figure 1, that present embodiment provides comprises bolt head 1 and screw rod 2, between bolt head 1 and screw rod 2, is provided with eel-like figure polished rod 3, and said screw rod 2 be a ledge structure, screw rod top bar 22 and screw rod to get out of a predicament or an embarrassing situation between 21 be the arc transition structure.
The wind-powered electricity generation bolt that present embodiment obtains; It is provided with eel-like figure polished rod 3 between bolt head 1 and screw rod 2; The ledge structure that while screw rod 2 differs for thickness; Make the connection part of each part of wind power plant impact down and can avoid loosening receiving variable force, thus effectively keep wind power plant firmly with stable, guaranteed the Security when wind power plant is worked.
