Aeroengine axisymmetric contracting nozzle is provided with adjustment sheet for adjusting pneumatic stream, and adjustment sheet wall is easily subject to the ablation of high-temperature fuel gas, needs to increase metallic material heat screen mechanism at adjustment sheet wall and blocks high-temperature fuel gas.Compared to traditional metallic material, composite material, due to advantages such as temperature tolerance are strong, proportion is low, fire-resistant gas scouring capability is strong, is applicable to heat screen.But composite material has following restrictive condition: be difficult to heat under hot environment with high expansion ratio metal material materials and parts and mate, on composite material element, hole arranged and influential point of tendons reduces fiber continuity thus reduction mechanical property, and composite material heat screen cost height need possess interchangeability.The problem needing now solution badly how to design a kind of bindiny mechanism can overcome above-mentioned shortcoming.
Model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provide a kind of simple and reasonable, make the hot flap heat screen bindiny mechanism of mating of composite material heat screen and high expansion ratio metal material materials and parts.
The purpose of this utility model is achieved through the following technical solutions: a kind of flap heat screen bindiny mechanism, comprise support, bolt, lining, wherein, support is structure bracket base being provided with hollow seats, hollow seats and bracket base parallel surface are provided with bar hole, the nut of bolt is stuck in described hollow seats, and the screw rod of bolt stretches out bar hole and cover has lining.
In such scheme preferably, Bracket setting is between composite material heat screen and adjustment sheet, and bracket base is fixedly connected with composite material heat screen by rivet by described support, and adjustment sheet is fixed on bolt, between lining and nut by nut.
In above-mentioned either a program preferably, the outer annular diameter of lining is greater than the width of the bar hole on support.
In above-mentioned either a program preferably, nut is connected with bolt thread, and the diameter of the nut of bolt is greater than the strip hole on described support.
In above-mentioned either a program preferably, the quantity of the described support be connected with adjusting vane is at least two.
The beneficial effect of flap heat screen bindiny mechanism provided by the utility model is, be convenient to assembling and dismounting, device stability is high, safe and reliable, be easy to realize, the flap heat screen bindiny mechanism provided by arranging the utility model between heat screen with adjustment sheet makes heat screen mate with high expansion ratio metallic material heat in high temperature environments.
