Description

Gasoline engine generator unit

Technical field

The utility model relates to a kind of universal generator.

Background technique

So-called gasoline engine generator unit, be called for short logical machine, refer to the petrol engine except automobile-used and specific use, its nominal power is generally at below 30kW.It is mainly as the supporting power of agricultural equipment for plant protection, small farm machine, graden machine, generator set, building machinery, outboard machinery etc.Because general small-size gasoline engine volume is little, lightweight, low price, easy to use, so occupy critical positions in various machine coordination.

Scaffold is namely for loading the support body of logical machine; comprise multiple constituent element due to logical machine and there is certain quality; so general logical machine all needs the scaffold setting up frame form; that certain protective action is played to equipment on the one hand; can be used for fixing each parts on the other hand; by as a whole for each constituent elementization of gasoline engine generator, under scaffold, install the carrying that the devices such as roller can carry out logical machine easily.

Fuel tank is arranged on the top of logical machine usually, specifically, can be that on fuel tank, the mounting plate of level connects with the frame of upper rack.But due to the position relationship of fuel tank and frame, be that the mode combined by bolt and otic placode is connected therebetween, and after installing, the axis of bolt is all positioned at vertically substantially.In the situation such as assembling, transport, work of logical machine, inevitable fuel tank can produce relative displacement or vibrations because of the effect of external force with frame, if above-mentioned bolt connection structure, the power of substantially horizontal can with on the present bolt of the form body of shearing, and bolt is to the amount of bearing of shearing much smaller than the amount of bearing to pulling force usually, the structural damage phenomenon at bolt position just becomes particularly outstanding.

Model utility content

The utility model is intended to provide a kind of gasoline engine generator unit, to solve the problem of the easy shear destruction of bolt in existing connecting structure.

Patent formula: the gasoline engine generator unit in this programme, it is characterized in that: comprise frame, panel and working part, working position is in the middle part of frame, the rear portion of frame is located at by panel, working part comprises fuel tank, vent systems, power system and electric system, frame comprises upper frame and lower frame, lower frame is rectangular, upper frame comprises front bar and the rear bar of level, upper frame also comprises the side lever of two levels, front bar is lower than the level height of rear bar, the rear end of two side levers connects with the two ends of rear bar respectively, the front end of two side levers is connected with the two ends of front bar by two vertical rods, the front portion of lower frame is connected with the two ends of front bar by two struts, the surrounding of fuel tank simultaneously and front bar, vertical rod and rear bar connect, fuel tank and vertical rod are by the Bolt Connection of substantially horizontal.

Whole frame is a stable framework, fuel tank can connect with front bar, vertical rod and rear bar, the fixed point of fuel tank is in a three dimensional space, and the bolt of point of attachment is no longer vertically, fuel tank and vertical rod are by the Bolt Connection of substantially horizontal, when fuel tank in frame is subject to horizontal applied force, the bolt of substantially horizontal can pass through tension or pressurized, reduces the shearing suffered by vertical bolt, improve the receive strength rationality of total, add the life-span of equipment.

Further, comprise joining frame and handle, handle is articulated with frame and can rotates around it, frame and handle are provided with the locating stud and locating slot that offset, locating stud and locating slot are connected in frame and handle or locating stud and locating slot respectively and are connected in handle and frame respectively, and locating stud is provided with the spring making it tend in locating slot.

In this programme, the handle in scaffold frame can rotate, but when locating stud falls in locating slot, handle cannot rotate.When handle turn to be affixed with frame time, the spatial volume that can reduce gasoline engine generator unit greatly takies, and after in frame, rotatory handling is launched, keep in locating stud clamping and locating slot, thus the rotation of restriction handle, now handle is in the state of expansion, can be used for staff easily push and pull bar to copy body mechanically.When needing again folding handle, using external force to overcome the pulling force of spring, locating stud being deviate from from locating slot, can again realize freely rotating of handle.

Further, described locating slot is positioned on the positioning hole limit of circular arc, and locating stud is through positioning hole.Locating stud is constrained in positioning hole, can avoid the accident that generation locating stud is deviate from.

Further, positioning hole is 90 ° of circular arcs, and described locating slot comprises two locating slots at positioning hole two ends, and the bottom land normal of two locating slots is intersected in the rotation axis of handle.This scheme can ensure that handle can be fixed in two positions at a distance of 90 °, to adapt to different workplaces.

Further, handle is hinged in frame by rotating shaft, and locating stud is slidably connected in the cylindrical void in frame, and cylindrical void length-wise axis, towards the rotation axis of handle, is connected with extension spring between rotating shaft and locating stud.This scheme has carried out better constraint to the working position of locating stud, improves the convenience degree of use.

Further, handle is U-shaped, and handle one end is by locating slot and locating stud coupling location, the handle the other end is provided with connecting plate, frame is provided with lock hole, and connecting plate is provided with the plural dynamic lockhole corresponding with lock hole, is also provided with to fasten to wear pin in lock hole and dynamic lockhole simultaneously.When handle turns to different angles, then dynamic lockhole that may be different is relative with unique lock hole, as handle need be made to keep this angle, can fasten in lock hole and dynamic lockhole, with the angle of locked handle by wearing pin.

Further, wear pin and be provided with draw ring, so that extract.
