Lid in the utility model is made by multilayer material is compound, and not only weight is lighter, can effectively reduce the weight of whole agricultural aircraft, and structural strength is good, is difficult for damagedly, can increase service life of lid.
The utility model is in closing top cover, first the gap between crosspiece under fixture block and lid is snapped in to the edge of fuselage top end opening, lid is carried out on fuselage to Primary Location, then stir two driving levers simultaneously, make the direction motion of two driving levers to lid center, now spring is compressed, when driving lever motion, together with the latch that drive is fixedly connected with driving lever, move, make in the retraction lid edge, outer end of latch, like this lid completely spiral-lock at the opening part on fuselage top, and fuselage top end opening is sealed, finally unclamp driving lever, under the effect of recoil of spring power, driving lever and latch reset, the inwall of the outer end of latch and fuselage top end opening pushes against, under the combined action of two latches and a fixture block, top cover tightly spiral-lock at fuselage top, can not occur loosening or come off.In the time that top cover need to be opened, only need stir driving lever according to above operating mode, make latch retract, then around the fixture block lid that upwards overturns.
Between the each adjacent layer of described lid (1), by being adhesively fixed, can reduce production costs like this, it is fixing more firm to make again.
In order to beautify outward appearance, and strengthen resistance to abrasion and the anti-corrosive properties of product, be coated with epoxy enamelled coating (1f) at the end face of described aviation alkali-free glass layer of cloth (1a).
In guaranteeing properties of product, save as much as possible material, the thickness of described epoxy enamelled coating (1f) is 0.05mm.
For the ease of drawing materials, the thickness of described aviation alkali-free glass layer of cloth (1a) is 0.08mm.
In order conveniently to draw materials, the thickness of described high-density glass layer of cloth (1b) is 0.1mm.
Described fixture block (2) is " Z " shape, and the bottom surface of the upper crosspiece of fixture block (2) and lid (1) fits, and fixes by bonding or screw, between the lower crosspiece of fixture block (2) and the bottom surface of lid (1), has gap.Above structure on the one hand between fixture block and lid area of contact large, connect not only firmly but also reliable; On the other hand, the gap under fixture block between crosspiece and lid bottom surface can conveniently be located, and is conducive to lid and fuselage clamping is firm.
For the end face of positioning seat is firmly connected with the bottom surface of lid, the end face of described positioning seat (3) fits fixing by bottom surface bonding or screw and lid (1).
For simplified structure, facilitate processing and fabricating, prevent that latch from coming off, the inner of described latch (4) is bulb, this bulb is spacing by interior journal stirrup (3a).
Beneficial effect: the utility model lid is made up of composite material, not only lightweight, and also structural strength is good; The utility model is by arranging a fixture block and two telescopic latches, quickly and easily folding covers at the edge of lid bottom surface.
