Abstract
The utility model discloses a hand gasoline driven circular saw in the cutting device field, which comprises a gasoline engine, wherein, a front handle and a back handle are fixed corresponding to an engine shell of the gasoline engine, the output shaft of the gasoline engine is connected with a drive chain wheel which is connected with a driven chain wheel through a chain in a drive way, an idler wheel is provided by having the same axis with the driven chain wheel, and the idler wheel meshes with an output gear. The drive chain wheel, the driven chain wheel, the idler wheel and the output gear are arranged in a gearbox, the end part of the axis of the output gear which extends out of the gearbox is provided with circular saw blades, a protective cover is arranged outside the circular saw blades which extend out of an opening at the lower side of the protective cover, and a guide plate is arranged at the opening of the protective cover. When in cutting, the counterforce of a wordpiece is transferred to the device body by the guide plate, enabling the operator to hold more easily. The hand gasoline driven circular saw can be used for cutting materials such as metals, woods, plastics, stones, concrete, etc., and is particularly applied to field construction works of fire fighting, traffic, electric power, pipeline and building industries.
Description
Technical field
The utility model relates to a kind of hand held cutting tool.
Background technology
Traditional circular sawing machine adopts motor as power source mostly, and must be equipped with power supply could operate as normal, operation in the open air.Also there is the part cutting machine to adopt portable gasoline engine to be used as power; this portable gasoline cutting machine; mainly comprise front handlebar and back handle; before; back handle and gasoline engine casing relative fixed; the output axle head of gasoline engine is provided with driving pulley; driving pulley is connected with driven pulley through belt transmission; the driven pulley axle head is connected with the resin wheel sheet; the resin wheel sheet is provided with fixedly protective cover outward; existing band transmission design makes that distance is far away between the rotating shaft of the output shaft of prime mover and resin wheel sheet; make center of gravity away from operating handle; so the resin wheel sheet can only be the resin wheel sheet, during its work, can only do grinding and can not realize rapidly and efficiently cutting operation; and the time there is the reaction force of grinding in work, so there is potential safety hazard in manual operations.
The utility model content
The purpose of this utility model is to provide a kind of hand-hold gasoline power circular saw machine, uses the hand-hold gasoline machine to be power source, can overcome the cutting reaction force, reaches the purpose of safety, efficient cutting.
To achieve these goals; a kind of hand-hold gasoline power circular saw machine that the utility model provides; comprise gasoline engine; with gasoline engine casing relative fixed front handlebar and back handle are arranged; the output shaft of gasoline engine is connected with drive sprocket; drive sprocket is connected with a driven sprocket through chain; with the coaxial idler gear that is provided with of driven sprocket; idler gear is meshed with output gear; described drive sprocket; driven sprocket; idler gear and output gear are arranged in the gearbox; the shaft extension of output gear goes out the outer end of gearbox saw blade is installed; saw blade is provided with protective cover outward; described saw blade stretches out from the opening part of protective cover downside, and the opening part of protective cover is provided with guide plate.
The utility model is cut the below that material is pressed in guide plate when cutting operation, the reaction that produces during the saw blade cutting is offset by guide plate, makes the operator easily hand-held, low-disturbance power; Its connected mode causes its center of gravity near handle, is convenient to grip; Compared with prior art, the utility model compact conformation can overcome the cutting reaction force, cut safer, efficient, its range of application is wider, can cut timber, plastics and metallic plate section bar, can be widely used in the field work that industries such as worker are built in fire-fighting, traffic, electric power, pipeline.
As further improvement of the utility model; described gearbox and protective cover one end are hinged; it is the locating slot of pivot that the protective cover side is provided with a pin joint with gearbox and protective cover; be provided with locating shaft in the locating slot; described locating shaft and gearbox relative fixed, locating shaft is in locking nut is fixed on locating slot on the protective cover.Protective cover can rotate around pin joint, and it can hide saw blade when rotating, when usual shutdown; saw blade can be hidden to guarantee safety, when work, can open guard shield; expose saw blade, make locating shaft and protective cover locking by locking nut, the overhang of saw blade also can be regulated.
For ease of chain tension, at least one side of the chain in the described gearbox is provided with regulating wheel.
Description of drawings:
Fig. 1 is a user mode structural representation of the present utility model.
Fig. 2 is a closed condition schematic diagram of the present utility model.
Fig. 3 is a gearbox transmission mechanism schematic diagram.
Among the figure, 1 back handle, 2 protective covers, 3 locating shafts, 4 guide plates, 5 saw blades, 6 jointed shafts, 7 front handlebars, 8 gearboxes, 9 output gears, 10 idler gears, 11 driven sprockets, 12,15 regulating wheels, 13 chains, 14 drive sprockets, 16 locating slots.
The specific embodiment
As figure, be hand-hold gasoline power circular saw machine, comprise gasoline engine, with be fixed with front handlebar 7 and back handle 1 on the gasoline engine casing, the output shaft of gasoline engine is connected with drive sprocket 14, drive sprocket 14 is connected with a driven sprocket 11 through chain 13, with the driven sprocket 11 coaxial idler gears 10 that are provided with, idler gear 10 is meshed with output gear 9, described drive sprocket 14, driven sprocket 11, idler gear 10 and output gear 9 are arranged in the gearbox 8, the shaft extension of output gear 9 goes out the outer end of gearbox saw blade 5 is installed, and this saw blade 5 can be diamond circular saw blade or alloy saw blade; Be provided with protective cover 2 outside the saw blade 5, saw blade 5 stretches out from the opening part of the downside of protective cover 2, and the opening part of protective cover 2 is provided with guide plate 4; Gearbox 8 and protective cover 2 one ends are hinged, it is the locating slot 16 of pivot that protective cover 2 sides are provided with a pin joint 6 with gearbox 8 and protective cover 2, be provided with locating shaft 3 in the locating slot 16, locating shaft 3 and gearbox 8 relative fixed, locating shaft 3 is in locking nut is fixed on locating slot 16 on the protective cover 2; Chain 13 both sides in the gearbox 8 are respectively equipped with regulating wheel 12,15.
