Abstract

A full-automatic two-way air cylinder comprises an air cylinder body (20), a piston (21), piston rods (26), an air inlet switch (24) and an air outlet switch (25). The full-automatic two-way air cylinder is characterized in that the two ends of the piston are provided with the piston rods (26), the piston rods (26) are limited by center holes in the two ends of the air cylinder body (20), an air inlet channel (22) and an air outlet channel (23) which are separated are arranged in the piston rods (26) respectively, and the axisymmetric air inlet switch (24) and the axisymmetric air outlet switch (25) are arranged in the piston (21) respectively. Due to the structure, when high-pressure air pushes the piston (21) to move, the air inlet switch (24) and the air outlet switch (25) are driven to move, when a stopping point is approached, the air inlet switch (24) and the air outlet switch (25) touch the cylinder wall, and therefore the position of the air inlet switch (24) and the position of the air outlet switch (25) are changed; the position of the air inlet switch (24) and the position of the air outlet switch (25) remain unchanged under the difference of air pressures on the two sides of the piston(21) until next touch occurs, and therefore air suction and air exhausting on the two sides of the piston (21) in the air cylinder body (20) are changed by changing the position of the air inlet switch (24) and the position of the air outlet switch (25) to enable the full-automatic two-way air cylinder to move automatically.

Description

Full-automatic bidirectional cylinder

[technical field]

The present invention relates to a kind of power plant, specifically a kind of full-automatic bidirectional cylinder.

[technical background]

At present, beidirectional cylinder, also needs air distributing device mostly, and can only be external, and so, complex structure, takes up room large, and user cost is high; Although also there is built-in two-action cylinder, complex structure also, tightness is bad.

[summary of the invention]

The utility model provides a kind of full-automatic bidirectional cylinder for overcoming the deficiencies in the prior art: comprise cylinder, piston, piston rod, air inlet switch, air discharge cook, it is characterized in that piston two ends are provided with piston rod, center hole by cylinder two ends limits, in piston rod, be respectively equipped with the intake duct of separation, air outlet flue, in piston, be respectively equipped with axisymmetric air inlet switch and axisymmetric air discharge cook, so structure, when pressurized gas promote piston movement, drive air inlet switch and air discharge cook motion, in the time approaching stop, touch casing wall, thereby the position of conversion air inlet switch and air discharge cook, its position remains unchanged under the draught head of piston both sides, until touching next time, so automatically, the position that changes air inlet switch and air discharge cook converts air inlet and the exhaust of piston both sides, and cause full-automatic bidirectional cylinder automatically to operate.

[brief description of the drawings]

Fig. 1 is easy structure schematic diagram of the present invention;

Fig. 2 is that cylinder moving has touched that intake and exhaust switch makes air-flow changed course during to the left side and schematic diagram that cylinder is moved right;

When Fig. 3 is cylinder moving to the right, having touched intake and exhaust switch makes air-flow changed course and makes the schematic diagram of cylinder to left movement;

[embodiment]

A kind of full-automatic bidirectional cylinder, as Fig. 1, comprises cylinder 20, piston 21, piston rod 26, the intake duct 22 in piston rod, the air outlet flue 23 in piston rod, air inlet switch 24 in piston and air discharge cook 25, the solid arrow in Fig. 1-3 is air motion situation, dotted arrow is cylinder moving direction.

The present invention implements like this:

If piston, piston rod is motionless, and cylinder moves (vice versa), as Fig. 2, air-flow is entered by air inlet runner 22, forces cylinder 20 to move, when cylinder 20 moves to the left side (stop), casing wall touching air inlet switch 24 and air discharge cook 25, compel to cause it to move to the position as Fig. 2, then under the draught head of piston both sides, keep this position, air-flow enters cylinder one side by air inlet switch 24, cylinder opposite side gas is discharged through grate flow channel 23 by air discharge cook 25, and cylinder moves right.

As Fig. 3, when cylinder 20 moves to the right (stop), casing wall touching air inlet switch 24 and air discharge cook 25, compel to cause it to move to the position as Fig. 3, then under the draught head of piston both sides, keep this position, air-flow enters cylinder one side by air inlet switch 24, and cylinder opposite side gas is discharged through grate flow channel 23 by air discharge cook 25, and cylinder is to left movement.

So circulation, full-automatic bidirectional cylinder operates automatically.

Claims

1. a full-automatic bidirectional cylinder, comprise cylinder (20), piston (21), piston rod (26), air inlet switch (24), air discharge cook (25), it is characterized in that piston (21) two ends are provided with piston rod (26), limited by the center hole at cylinder (20) two ends, in piston rod (26), be respectively equipped with the intake duct (22) of separation, air outlet flue (23), in piston (21), be respectively equipped with axisymmetric air inlet switch (24) and axisymmetric air discharge cook (25), so structure, when pressurized gas promote piston (21) motion, drive air inlet switch (24) and air discharge cook (25) motion, in the time approaching stop, touch casing wall, thereby the position of conversion air inlet switch (24) and air discharge cook (25), its position remains unchanged under the draught head of piston (21) both sides, until touching next time, so automatically, the position that changes air inlet switch (24) and air discharge cook (25) converts air inlet and the exhaust of cylinder (20) inner carrier (21) both sides, and cause full-automatic bidirectional cylinder automatically to operate.
