Description
Technical field
The present invention relates to generator unit structure, and be particularly related to a kind of self-locking device.
Background technique
The gasoline engine generator group is a kind of power generating equipment, mean take gasoline etc. as fuel, other forms of energy conversion to be become the machinery of electric energy, it is driven by water turbine, steam turbine, diesel engine or other dynamic power machines, with current, air-flow, the Conversion of Energy that fuel combustion or nuclear fission produce is that mechanical energy is passed to generator, then by generator, is converted to electric energy.Generator is in industrial and agricultural production, and national defence, have been widely used in science and technology and daily life.
Generator consists of parts such as stator, rotor, end cap and bearings usually.Other structural members that stator holds group, support by stator iron core, line and fixes these parts form.Rotor is comprised of parts such as rotor iron core (or magnetic pole, magnetic grip) winding, retaining ring, center ring, slip ring, fan and rotating shafts.With the stator of generator, rotor assembles, and rotor can be rotated in stator, does the motion of cutting magnetic line by bearing and end cap, thereby produces induced potential, by tenminal block, draws, and is connected in loop, has just produced electric current.
Motor is chemical energy to be converted into the machine of mechanical energy, in fact its conversion process is exactly the process of work cycle, be exactly to be fuel by in combustion cylinders in simple terms, produce kinetic energy, drive the motion of the piston reciprocating in cylinder, drive thus the connecting rod and the crank that is connected with connecting rod that is connected on piston, around crankshaft center, make reciprocal circular movement, and outputting power.A work cycle includes four piston strokes (so-called piston stroke just refers to that piston is by the process of top dead center to the distance lower dead center): intake stroke, compression stroke, expansion stroke (expansion space stroke) and exhaust stroke.
At present, existing gasoline engine generator group is in use very convenient, but, the at present movement of gasoline engine generator group is unusual inconvenience but, although this is because gasoline engine generator group volume is not very too large, but but very heavy, generally, wanting to depend merely on manpower and move a small-sized gasoline engine generator group, is almost also impossible, for this situation, the research staff is chosen in the below of gasoline engine generator group and loads onto roller, fits a handle on a side, due to the flexibility of handle rotation, always collide the surface of gasoline engine generator group, affected use.
Summary of the invention
Collide too flexibly gasoline engine generator group cosmetic issue in order to solve handle in prior art, but the invention provides a kind of fixed handle.
In order to achieve the above object, the invention provides a kind of self-locking device, comprise: lower cover, described lower cover is divided into three parts, be respectively the first lower cover attachment portion, lower cover intermediate portion and the second lower cover attachment portion, described the first lower cover attachment portion and described lower cover intermediate portion are fixedly linked, and described lower cover intermediate portion is connected with described the second lower cover attachment portion, are provided with screw on described the first lower cover attachment portion and described the second lower cover attachment portion; Upper cover, described upper cover is divided into three parts, be respectively the first upper cover attachment portion, upper cover intermediate portion and the second upper cover attachment portion, described the first upper cover attachment portion and described upper cover intermediate portion are fixedly linked, described upper cover intermediate portion is connected with described the second upper cover attachment portion, be provided with screw on described the first upper cover attachment portion and described the second upper cover attachment portion, described upper cover intermediate portion and described lower cover intermediate portion in conjunction with the time be a hollow circular cylinder; Two lockplates, be parallel placement, all with described upper cover, is connected.
Optionally, be provided with two screws on described the first lower cover attachment portion, be provided with a screw on described the second lower cover attachment portion.
Optionally, be provided with two screws on described the second upper cover attachment portion, be provided with a screw on described the second lower cover attachment portion.
The beneficial effect of a kind of self-locking device of the present invention is: self-locking device provided by the invention can be at horizontal position and vertical position fixed handle, thereby has avoided handle to rock the surface of clashing into the gasoline engine generator group.
