Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.

The invention provides a force amplifier which comprises two supporting plates 1, wherein a force amplifier is arranged between the two supporting plates 1. The force amplification mechanism comprises two double-layer link mechanisms 2 and two gear sets 3. The double-layer link mechanism 2 is provided with two layers of connecting rods 21, each layer is provided with a plurality of connecting rods 21, the connecting rods 21 on the same layer are arranged in parallel towards the same direction, and the two layers of connecting rods 21 are perpendicular to each other. The rotating shaft 4 is connected at the intersection of the upper and lower two-layer connecting rods 21, and the rotating shaft 4 is also used for the rotating connection at the intersection of the two-layer connecting rods 21 in the other two-layer connecting rod mechanism 2, that is, the opposite intersection points on the two-layer connecting rod mechanisms 2 share one rotating shaft 4.

The gear train 3 is arranged between the two double-deck linkages 2. Each gear set 3 comprises a fixed gear 31 and two loose gears 32, the two loose gears 32 meshing with the fixed gear 31. The rotating shaft 4 between the two-layer link mechanism 2 penetrates through the fixed gear 31 and the movable gear 32, and the fixed gear 31 and the movable gear 32 are fixedly connected with the corresponding rotating shaft 4.

The input ends of the force amplification mechanism are provided as two connecting rods 21. The output end of the force increasing mechanism is the rotating shaft 4 farthest from the input end.

It should be noted that two ends of the rotating shaft 4 are respectively connected to the two support plates 1, but a hexagonal prism 5 is further respectively fixed on the rotating shaft 4 of the four movable gears 32 and one rotating shaft 4 located in the middle of the double-layer link mechanism 2. The hexagonal prism 5 protrudes from the support plate 1. Further, a chute 11 is formed in the support plate 1, and the hexagonal prism 5 penetrates the support plate 1 through the chute 11. The movement of the movable gear 32 is restricted by the provision of the slide groove 11. The chute 11 near the input end of the force amplifier is short and the chute 11 near the output end of the force amplifier is long. When the force-increasing mechanism moves, the movable gear 32 not only translates along the chute 11, but also rotates relative to the fixed gear 31.

The force multiplier further comprises a first lever mechanism 6 and a second lever mechanism 7. The first lever mechanism 6 is located on the side of the support plate 1 facing away from the force amplification mechanism. The first lever mechanism 6 includes a pair of first levers 61, a pair of second levers 62, a pair of third levers 63, a pair of fourth levers 64, and a pair of fifth levers 65. One end of the first lever 61 is penetrated by a hexagonal prism 5 close to the input end of the force increasing mechanism; the other end of the first lever 61 is connected with the second lever 62 through a pin shaft; the other end of the second lever 62 is connected with one end of the third lever 63 through a pin shaft; the other end of the third lever 63 is connected with one end of the fourth lever 64 through a pin shaft; the other end of the fourth lever 64 is connected with the fifth lever 65 through a pin shaft; the other end of the fifth lever 65 is penetrated by a hexagonal prism 5 close to the output end of the force amplifier. The two third levers 63 are arranged in a crossed mode, and the crossed position of the third lever 63 is penetrated through the hexagonal prism 5 corresponding to the middle of the double-layer connecting rod mechanism 2. The two second levers 62 are arranged in a crossed mode, and the two fifth levers 65 are arranged in a crossed mode. When the first lever 61 moves, the 5 th lever 65 is driven to move along the chute 11.

The second lever mechanism 7 includes a pair of six levers 71, a pair of seven levers 72, and a pair of eight levers 73. One end of the sixth lever 71 is connected with one end of the seventh lever 72 through a pin shaft, and the other end of the seventh lever 72 is connected with one end of the fifth lever 65 connected with the hexagonal prism 5. Two ends of the eighth lever 73 are respectively connected with the six lever 71 and the seven lever 72 which are not connected through pin shafts. The two sixth levers 71 are arranged in a crossed mode, the two seventh levers 72 are arranged in a crossed mode, and the two eighth levers 73 are arranged in a crossed mode. When the six-size lever 71 moves, the eight-size lever 73 is driven to move along the chute 11.

When the force amplifier is used, the output end of the force amplifier serves as the output end of the force amplifier, the rotating shaft 4 of the output end of the force amplifier is connected with a crankshaft for applying work, and the two No. six levers 71 of the second lever mechanism 7 are connected with the crankshaft for inputting power. The size of the crankshaft for power input is smaller than the diameter of the crankshaft for work. When the two sixth levers 71 of the second lever mechanism 7 are connected with the crankshaft, the two sixth levers 71 are connected with a connecting arm, and the connecting arm is connected with the crankshaft through a connecting rod 21. When the crankshaft at the input end of the force amplifier rotates, the two sixth levers 71 in the second lever mechanism 7 are driven to move, and meanwhile, the first lever mechanism 6 and the force amplifier can be driven to move. When the first lever mechanism 6, the second lever mechanism 7 and the force increasing mechanism are used in a combined mode, the force arm can be increased by multiple times and can be larger than 120 times of the resistance arm, output power is provided, the machine can reciprocate, and the connecting rod 21 is driven to work through a crankshaft.
