Description

[Brief explanation of drawings]

FIG. 1 is a perspective view of a connecting rod and a metal part connected by a bent part and integrated into one body. Second
The figure is a perspective view of the entire crankshaft. FIG. 3 is a structural diagram in which the piston has reached the top dead center, the balance plate is also upright, the cam protrusion has no effect on the push-up rotation shaft, and there is also the force of the restoring spring, so that the connecting rod and the metal part are in close contact. Figure 4 shows that the piston is lowered and the balance plate is approximately 90
It is a structural diagram in a state in which the push-up rotation axis is at its highest position on the tilted cam protrusion, and the connecting rod and the metal part are opened and separated using the bending part as a fulcrum, and the piston is pushed upward. Figure 5 shows that as the crankshaft rotates further, the inclination of the balance plate is reversed, and the cam protrusion is also positioned downward, so there is no pushing up of the connecting rod at all, and the force of the restoring spring causes the metal part and the connecting rod to come into close contact. FIG. 3 is a structural diagram showing a state in which the piston is still raised. 1 is a cylinder, 2 is a piston, 3 is a crankshaft, 4 is a connecting rod, 5 is a bent part, 6 is
7 is a metal part, 7 is a push-up rotation shaft, 8 is a balance plate, 9 is a cam projection, and 10 is a restoring spring.

Amendment February 28, 1982 The name of the invention is amended as follows. Title of the invention: Explosion pressure reinforcement device by bending the connecting rod in an internal combustion engine The scope of the utility model registration claims and the brief description of the drawings are amended as follows.

[Claims for Utility Model Registration] A metal part separated at the large end of a connecting rod 4 interposed between a piston 2 sliding on the inner wall surface of a cylinder 1 and a crankshaft 3 in an internal combustion engine. 6
, are connected by a bending part 5, and integrally connected to a crankshaft 3, in an internal combustion engine, an explosion pressure reinforcement device by bending a connecting rod. A cam protrusion 9 disposed on a component balance plate 8 of the connected crankshaft 3 acts on one end of the bent portion of the connecting rod, in conjunction with the utility model registration claim 1, Explosion pressure reinforcement device by bending the connecting rod in an internal combustion engine.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a connecting rod and a metal part connected by a bent part and integrated into one body. Second
The figure is a perspective view of the entire crankshaft. Figure 3 is a structural operation diagram in which the piston has reached the top dead center, the balance plate is upright, the cam protrusion has no effect on the push-up rotation axis, and there is also the force of the restoring spring, so that the connecting rod and the metal part are in close contact. . Figure 4 shows the structure in which the piston is lowered, the balance plate angle is tilted at 90 degrees, the push-up rotation axis is pushed up to the cam protrusion, the connecting rod and the metal part are opened and separated, and the piston is pushed upward. It is an operation diagram. Figure 5 shows that as the crankshaft rotates further, the inclination of the balance plate is reversed, and since it is located below the cam protrusion, there is no pushing up on the connecting rod at all, and the metal part and the connecting rod are in close contact with each other due to the restoring spring, etc. FIG. 3 is a structural operation diagram showing a state in which the piston is still raised; 1 is a cylinder, 2 is a piston, 3 is a crankshaft, 4 is a connecting rod, 5 is a bent part, 6 is
7 is a metal part, 7 is a push-up rotation shaft, 8 is a balance plate, 9 is a cam projection, and 10 is a restoring spring.

Claims (1)

[Claims for Utility Model Registration] In an internal combustion engine, a metal portion 6 separated at the large end of a connecting rod 4 interposed between a piston 2 sliding on the inner wall surface of a cylinder 1 and a crankshaft 3 is bent. They are connected by part 5 and become an integral part. A push-up rotation shaft 7 is disposed on the connecting rod 4 so as to face the bending portion 5 . Components of crankshaft 3, balance plate 8
Cam protrusions 9 are arranged on both inner surfaces of the piston 2.
When the crankshaft 3 enters an explosive downward movement, the balance plate 8 deepens its inclination angle in order to convert its pressure into rotation, and at the same time the cam protrusion 9 acts on the push-up rotation shaft 7.
Even if the metal part 6 is in close contact with the crankshaft 3, the connecting rod 4 is in a state where the opening is separated using the bent part 5 as a fulcrum, and the piston 2 connected at the small end is pushed up. As the rotation progresses further and the angle of the balance plate 8 becomes deeper, the action of the cam protrusion 9 on the push-up rotation shaft 7 is also removed, and the restoring spring 10
The explosion pressure reinforcement device by bending the connecting rod is characterized in that the connecting rod 4 and the metal part 6 come into close contact with each other and return to their original state due to the force.
