Description

Lever power machine

Technical field

The utility model relates to a kind of power plant, is a kind of lever power machine that is mainly used in outputting power specifically.

Background technique

The device that produces power is many, for example motor, diesel engine and petrol engine etc., and the general more complicated of these power equipment structures, the cost height needs consumes energy and loss big, so the operating cost height.

Along with the minimizing day by day as the natural oil resource of diesel engine and petrol engine fuel, and the aggravation that various countries' industrialization is developed by leaps and bounds, consumption of petroleum amount are increasing year by year significantly, and this disposable energy availability and demand contradiction of earth Heaven burning petroleum is become increasingly conspicuous.Petroleum resources limited on the earth are being subjected to unconfined exploitation, will certainly be exhausted.

For reduce to rely on the natural oil resource better and reduce cost, the needs of aspect such as environmental protection, the power equipment that wind energy, solar energy etc. have occurred, but up to the present, this class technology is still immature, and be subjected to the restriction and the climatic influences of geographical conditions, operating also exists many problems, does not therefore also obtain excellent popularization and uses.

Also there are many people to develop the mechanical laborsaving mode of many employings at present, utilize fewer power that output shaft is rotated by certain mechanical structure, produce power, be used for driving device equipment, but, and do not applied all because of unreasonable structure maybe can't produce enough a variety of causes such as power.

Summary of the invention

The purpose of this utility model provide a kind of simple in structure, cost is low, the lever power machine that is mainly used in power output of enough power can be provided.

The lever power machine that the utility model provides, it is that leverage and rotatingshaft are installed on frame, described leverage is made up of a pair of lever assembly, lever assembly one termination driving crank, the other end connects with rotatingshaft by toggle mechanism, when driving crank rotated, two lever assemblies of doing the opposite direction swing can alternately be stirred by toggle mechanism rotatingshaft is rotated.

Described lever assembly is made up of connecting rod and sleeve, sleeve is hinged on the support and can rotates around the hinged place, connecting rod one end is socketed on the driving crank, the other end stretches in the sleeve and can stretch in sleeve, described toggle mechanism comprises slide block that is fixed on the sleeve and the moving block that is installed on the rotatingshaft, and slide block cooperates with moving block.

Described moving block is a gear, and bar is stirred on the surface of slide block and gear matched, stir in the mouth of giving up the throne that bar is installed in slide block and inner end and slide block hinged, mouthful bottom surface finite place piece of giving up the throne.

Described rotatingshaft is connected to accelerator.

Accelerator is made up of a pair of big or small gear.

The utility model is owing to exert pressure to rotatingshaft by two lever assemblies of doing the opposite direction swing in the leverage, in the intersection swing rotatingshaft is rotated repeatedly, outputting power, can be by changing the arm of force length of lever assembly, or with the mode of lever assembly, thereby increase the power that is applied on the rotatingshaft by series connection.And accelerator can adopt multistage mode, and it is actual required that final rotating speed can be satisfied.The utility model is simple in structure, cost is low, and enough power can be provided, and is used for driving device equipment, thus better energy saving, reduce cost and satisfy the needs of environmental protection etc.

Embodiment

With reference to Fig. 1, Fig. 2, the lever power machine that the utility model provides, it is that leverage and rotatingshaft 4 are installed on frame 1, described leverage is made up of a pair of lever assembly 3, lever assembly 3 one termination driving cranks 2, the other end connects with rotatingshaft 4 by toggle mechanism, when driving crank 2 rotates, two lever assemblies 3 of doing opposite direction swing can alternately be stirred by toggle mechanism rotatingshaft 4 is rotated, rotatingshaft 4 is connected to accelerator 5, accelerator 5 is made up of a pair of big or small gear, can continue expansion, is three grades of acceleration as what show among Fig. 1.Driving crank 2 can be by manpower or driven by motor.

Described lever assembly 3 is made up of connecting rod 9 and sleeve 10, sleeve 10 is hinged on the support 6 and can rotates around the hinged place, connecting rod 9 one ends are socketed on the driving crank 2, the other end stretches into 10 li in sleeve and can stretch for 10 li at sleeve, described toggle mechanism comprises slide block 7 that is fixed on the sleeve 10 and the moving block 8 that is installed on the rotatingshaft 4, and slide block 7 cooperates with moving block 8.When driving crank 2 rotates like this, flexible by connecting rod 9 in 10 li in sleeve, thus can guarantee that the sleeve 10 in two lever assemblies 3 swings along the hinged place.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, described moving block 8 is a gear, slide block 7 is stirred bar 12 with the surface of gear matched, stirring bar 12, to be installed in give up the throne mouthfuls 11 li and the inner end of slide block hinged with slide block 7, and the mouth 11 bottom surface finite place pieces 13 of giving up the throne are stirred the quantity of bar 12 and decided by actual demand, can be one, two, three, four or the like, this moment, the surface of slide block 7 was an arc surface, and stirred bar 12 and lay by certain interval, was that tooth-formation of gear cooperates with moving block 8.

Above-mentioned leverage can continue expansion, as among Fig. 1 being the three grades of modes that adopt serial connection of adopting, and under equal conditions can be laborsaving.

Its working principle is: when giving driving crank 2 application of forces, driving crank 2 is in rotation process, driving two lever assemblies 3 swings around the sleeve 10 and the hinged outer opposite direction of doing of support 6, when wherein the slide block 7 in the lever assembly 3 is upwards swung, stir bar 12 landings to bounding means 13 in the slide block 7, be subjected to the supporting role of bounding means 13, can stir gear 8 in when swing and exert pressure, promote moving block 8 rotations, simultaneously, the slide block 7 in another lever assembly 3 is subjected to moving block 8 effects to lower swing, the bar 12 of stirring on this slide block 7 is return to lower swing and is given up the throne mouthfuls 11 li, hocket repeatedly, moving block 8 is with regard to the rotation that constantly is struck, and rotatingshaft 4 rotates, after accelerator 5 quickens, outputting power.
