Description
Technical field
The utility model belongs to agricultural vehicle technology field, specifically, and particularly four-axle aircraft top cover.
Background technology
Along with social development, the progress of science and technology, the work such as spray insecticide on a large scale in farmland, fertilising are progressively completed by unmanned vehicle.Top cover is the vitals on agricultural unmanned vehicle, plays closed fuselage upper port.Existing top cover is circular, and not only aesthetic property is poor, and positioning performance is not good; In addition, existing top cover is convertible structure, and locks by lockset, and in use, the folding of top cover is inconvenience very, complex operation not only, and waste time and energy, the convenience that very impact is used.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of positioning performance is good, the four-axle aircraft top cover of folding with convenience.
The technical solution of the utility model is as follows: a kind of four-axle aircraft top cover, there is lid (1), described lid (1) is the globoidal structure that middle high rim is low, and formed by the first support plate (2), the second support plate (3), the 3rd support plate (4) and the 4th support plate (5), these four support plates are pressed even circumferential and are distributed, the root of four support plates is connected as a single entity, and forms "+" character form structure, between described the first support plate (2) and the 4th support plate (5), the bottom surface of root connecting place is provided with the first positioning seat (7), the interior outer end of this first positioning seat (7) bottom is respectively arranged with the first interior journal stirrup (7a) and the first outer journal stirrup (7b), on the first inside and outside journal stirrup of described the first positioning seat (7), jointly wears set pin (11), between described the second support plate (3) and the 3rd support plate (4), the bottom surface of root connecting place is provided with the second positioning seat (6), the interior outer end of this second positioning seat (6) bottom is respectively arranged with the second interior journal stirrup (6a) and the second outer journal stirrup (6b), described the second positioning seat (6) second in, on outer journal stirrup, jointly wear removable pin (8), the outer end of this removable pin (8) exceeds the outer of lid (1), at the upper vertical fixedly driving lever (9) of described removable pin (8), the upper end of this driving lever (9) is through the second positioning seat (6) and the corresponding bar shaped via hole arranging of lid (1), on described removable pin (8), be set with spring (10), one end of this spring (10) and the second interior journal stirrup (6a) connect, the other end of spring (10) and driving lever (9) connect.
The utility model is designed to "+" font by lid, and not only handsome in appearance, generous, processing and fabricating is easy, and the lid good reliability of locating on fuselage, circumferential displacement can not occur.When closing top cover, first the gap between set pin and lid is snapped in to the edge of fuselage top end opening, lid is carried out on fuselage to Primary Location, then stir driving lever, make driving lever to the direction motion at lid center, now spring is compressed, in the time of driving lever motion, together with the removable pin that drive is fixedly connected with driving lever, move, make in the retraction lid edge, outer end of removable pin, 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 removable pin reset, the inwall of the outer end of removable pin and fuselage top end opening pushes against, under the combined action of removable pin and set pin, top cover tightly spiral-lock at fuselage top, can not occur loosening or come off.When top cover need to be opened, only need stir driving lever according to above operating mode, removable pin is retracted, then around the set pin lid that upwards overturns.
For the first positioning seat is firmly connected with lid, the end face of described the first positioning seat (7) fits fixing by bottom surface bonding or screw and lid (1).
For the second positioning seat is firmly connected with lid, the end face of described the second positioning seat (6) fits fixing by bottom surface bonding or screw and lid (1).
For simplified structure, facilitate processing and fabricating, prevent that removable pin from coming off, the inner of described removable pin (8) is bulb, this bulb is spacing by the second interior journal stirrup (6a).
For expendable weight, assurance structural strength, described lid (1) is made by carbon fiber composite material.
Beneficial effect: the utility model arranges set pin and telescopic movable pin by the edge in lid bottom surface, folding cover quickly and easily, has that design is ingenious, simple in structure, processing ease, is easy to the features such as transformation, improvement cost be low.
