Description
Technical Field
The utility model relates to a fixed reinforcing plate of wind-powered electricity generation frame blade.
Background
The fixed reinforcing plate of prior art apoplexy motor cabinet blade is shown in fig. 1, and it includes the reinforcing plate body, sets up in a plurality of connecting holes and mounting hole on the reinforcing plate body, and the blade is installed in the mounting hole, and the mounting hole is waist type hole, sets up the locking hole around the mounting hole, and the depth direction in locking hole and the depth direction of mounting hole are parallel, have only carried out axial positioning from this.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the defect that exists among the prior art, provide a fixed reinforcing plate of wind-powered electricity generation frame blade, the difficult pine of blade installation takes off stably.
In order to realize the technical effects, the utility model adopts the technical scheme that: the utility model provides a fixed reinforcing plate of wind-powered electricity generation frame blade, includes the reinforcing plate body, sets up in a plurality of connecting holes and mounting hole on the reinforcing plate body, the connecting hole and the depth direction of mounting hole all extends along the thickness direction of reinforcing plate body, its characterized in that, at least one terminal surface of reinforcing plate body is provided with a plurality of archs, the arch with the mounting hole one-to-one, just have in the arch with the perforation that the mounting hole corresponds, a plurality of locking holes have been seted up in the arch, the depth direction perpendicular to in locking hole the depth direction of mounting hole.
In a further improvement, the mounting hole is a kidney-shaped hole.
In a further refinement, the projection is shaped similarly to the mounting hole.
In a further improvement, the connecting hole is a unthreaded hole, and the locking hole is a threaded hole.
The utility model has the advantages and the beneficial effects that: through set up the arch all around at the mounting hole, and the blade installation back, with the locking through the downthehole screw of locking between blade and the arch, and locking hole perpendicular to mounting hole has not only realized axial positioning then, has realized radial positioning moreover, connects more stably, and the arch still plays protruding muscle's effect in addition, has improved the intensity of fixed plate.
