Carburetor air-fuel mixture adjustment assembly

An apparatus for adjusting the air-fuel ratio of a fuel mixture to be supplied to an engine. The apparatus has a pair of needle valve bodies and a pair of receptacles formed in a main body of a carburetor for receiving the needle valve bodies. Each needle valve body has a needle and a head. The needles are axially movable relative to a respective needle orifice. The needles may be axially advanced and retracted by rotating the needle valve bodies within the receptacles to respectively decrease and increase the flow of the fuel mixture around the needles and through the orifices. To prevent tampering with the needle valve body setting, the head of the needle valve body has an unconventional shape requiring a specialized tool to rotatably adjust the needle valve body. To further prevent tampering, the head is recessed with the main body of the carburetor. A retainer is disposed in the main body of the carburetor and receives the needle valve bodies to facilitate maintaining alignment of the needle valve bodies relative to the receptacles. The retainer assures that a constant fuel calibration setting is maintained through the orifices by resisting displacement of the needles due to such factors as external forces applied to the head of the needle valve body or engine vibration.

AI intelligent vertical take-off and landing and sea-land-air convertible aircraft carrier, carrier and universal carrying device

The invention relates to an AI intelligent vertical take-off and landing (VTOL) and sea-land-air convertible aircraft carrier, carrier and universal carrying device which are capable of changing motion modes among sea, land and air, and vertically taking off, landing and moving in any geographical environment. The universal carrying device comprises a carrying platform, connectors and engines. Thechange of the connectors controls the change of the distance / angle / direction of nozzles of the engines relative to the carrying platform, controls the change / locking / retraction / extension of the engines relative to the carrying platform, and controls the disconnection / connection / replacement / increment-and-decrement between the engines and the carrying platform. The change of the motion modes amongsea, land and air is realized through various changes of the engines relative to the carrying platform and the cooperation of assisting devices. The assisting devices comprise various compartments, airbags, an air passage, water bags, rails, rail vehicles, manipulator combinations, a movable repairing device, a movable cockpit / cargo compartment, a movable engine, a generator, an underwater jet-flow power device and other required equipment.

Multifunctional touring car

The invention relates to a multifunctional touring car, including a touring car body. The touring car body includes a cockpit, a chassis located at the back of the cockpit, a living cabin and a healthcabin fixed on the chassis. The top of the living cabin is provided with a hollow cabin roof. The cabin roof is connected with a shading shed frame through a telescopic rod. The two sides of the shading shed frame are respectively provided with solar panels. An inverted 'V' awning is formed through the solar panels of two sides. The interior of the living cabin is provided with stairs. The livingcabin is divided into two parts by the stairs, which are a bedroom and a living room. The bedroom part of the living cabin is provided with an assembled folding bed and a folding desk. The lower partof the living cabin is connected with a telescopic plate in intercalation. The side of the living cabin is provided with a living cabin door with an extended folding structure. The chassis is connected with an axle through an adjustable suspension system. The multifunctional touring car has the advantages of being simple in structure, convenient to use, capable of effectively saving the space ofoccupied space in the car and meanwhile enlarging the interior space of the car to improve the comfort degree according to the demand.

Steel structure roof framework

The invention discloses a steel structure roof framework. The steel structure roof framework comprises four support legs erected on the ground, and ceilings arranged at the tops of the support legs; every support leg is composed of a base and a plurality of support racks arranged on the base, wherein the plurality of support racks are stacked to the top from bottom to top, the bottom of an upper support rack is connected with the top of a lower support rack through bolts, a top support rack is connected with the ceilings, a bottom support rack is connected with the base, the lower portion of every support rack is a cavity capable of accommodating a telescopic cylinder, and the bottom of the support rack is provided with a guide bar tightly attached to the support rack. When the steel structure roof framework is assembled, workers only need to firmly connect the ceilings, hook hooks at the tops of the telescopic cylinders onto the horizontal connecting rods of the support racks, the telescopic cylinders move up to lift the ceilings up, then the workers connect side frames to the bottoms of lifted components to form the support racks and at the meantime the telescopic cylinders are reset, then the workers can hook the hooks onto next support racks for lifting up to repeated the processes above until the height of the ceilings reaches a set value to complete installation.
