Width of the width in described connection sheet portion more than main body fin portions, and corresponding two between two connection sheet portions
The line most between madial wall of individual fixed screw holes is located at the outside of main body fin portions.
In the back in two described connection sheet portions, integral vertical is provided with into fiber tube portion and wire vent pipe portion respectively, described
The central axis for entering fiber tube portion and wire vent pipe portion and main body fin portions central axes；One wire feed for forming trunnion portion
Passage enters fiber tube, connection sheet portion, main body fin portions, another connection sheet along the central axis successively continuous insertion
Portion, wire vent pipe portion, described wire feed passage are formed into a hole on the end face for entering fiber tube portion, and described wire feed passage is going out fiber tube
Wire vent hole is formed on the end face in portion.
It is described to enter tubaeform little in the big the inner in outer end in a hole.
Described wire vent hole is cylindrical.
Described connection sheet portion is rectangular.
Described modified polyetheretherketonefiber adopts PEEK450CA30.
The utility model compared with the existing technology, is selected and can be prepared as the modified polyetheretherketonefiber of structural material
Wire-feeding pipe intensity height, high temperature resistant, rub and examine that coefficient is low, wear-resistant, ageing-resistant, stable performance, can long-term work at high temperature, enter
Silk aperture stabilized contraction is little, is processed and formed at one time, it is to avoid the different problem of shrinkage factor after bi-material combination.
Description of the drawings
Fig. 1 is structural representation of the utility model in embodiment.
Top views of the Fig. 2 for Fig. 1.
