Description of the Invention: [Technical Field] The present invention relates to an improved structure of a piston body of an air compressor, and particularly to a structurally improved design of an upper cymbal of a piston body, and a spring is provided on a valve head of the piston body The piece and the reed are provided with an arc-shaped inner space, and the reed knife can be the outer part and the inner part of the inner piece. The gas pushes up the piece to push out from the gap a, and the outer ring area and the inner piece are both stressed. However, the reed is more easily bent, and the local stress concentration is less likely to occur, and the folds and marks appear in the bent portion, and the two positioning holes are provided on the yellow piece, and the reed is fixed to the valve head by bolts. The screw hole allows the reed to cover the intake passage on the valve head, and a stop groove is arranged on the other end of the cymbal. The stop block on the valve head passes through the piston body to actuate in the cylinder body, and the reed is The piston body is actuated to open the closing action to control the gas in and out, because the stopping block can resist the stopping groove and limit the amplitude of the reed opening, which can reduce the generation of the noise, and is a kind of high intake efficiency. Durable and quieter when operating Body structure improvement. # [Prior Art] _ 〆 In the piston body designed by the inventor, a ventilation passage is arranged under the valve head of the piston body, and a complete non-cutting reed is arranged on the top surface of the valve head, and one end of the reed is fixed on the valve head. Cover the channel at the other end and do not allow air to enter the cylinder chamber. When the piston body reciprocates in the cylinder chamber, the gas pushes the bobbin and enters the air chamber from the passage through the gap, or the clamshell is closed so that the gas passes through the passage, and the reed vibrates back and forth in a short time, also causing the metal The phenomenon of fatigue causes wrinkles in the reed-fixed joint with the valve head, causing damage. In addition, the inventor designed the crotch piece into a ring-shaped inner space, so that the celadon piece is divided into an outer ring zone 200831784 and an inner disc piece. 'When the air pushes the reed to overflow from the gap, the strict zone and the inner disc Uniform double to open force, to avoid localized localized damage or wrinkles of concentrated locale, is a two-stage design reed; no: is a complete non-cut or two-stage reed, piston body actuation At the same time, the middle piece quickly vibrates back and forth to cause the sound, and the vibration amplitude is too large. The clamshell is closed at the closing speed of the Japanese priest, and the air is easy to overflow. To prevent the vibration amplitude from being too large, the invention is to design a stop block on the valve head. The blade is designed with a stop groove, and the stopper block extends through the retaining groove, thereby limiting the vibration amplitude of the cymbal, and achieving a piston valve body with low noise and high air-closing efficiency. SUMMARY OF THE INVENTION The present invention relates to a piston body structure of an air compressor, and particularly relates to a structurally improved design of an upper reed of a piston body. On the valve head of the piston body, there are hundreds of U pieces, and a yellow piece is provided with a In the arc inner space, the cymbal piece can be divided into two parts: the outer ring area and the inner circle piece. The gas pushes up the reed piece to bend from the gap/m out of the outer ring area and the inner piece is forced to bend, so the spring The sheet is easier to bend, and the Lu is less prone to the local stress concentration phenomenon of the I. The crease is found in the bent portion, and a positioning hole is provided on the sheet. The bolt is used to fix the reed to the screw hole on the valve head, so that the 箦 is fixed. The piece covers the intake passage on the valve head, and a stop groove is arranged on the other end of the reed. The stop block on the valve head passes through the block. When the piston body is actuated in the cylinder block, the reed has the movement of the piston body. The closing action is opened to control the gas in and out, because the stopping block can resist the stopping groove and limit the vibrating field of the reed, which can reduce the noise generation, and is a kind of high-efficiency, more durable and more stable operation. The structure of the quiet piston body is improved. 6 200831784 [Embodiment] The present invention is a modification of the structure of the living substrate (2). Referring to the first figure, the invention comprises a piston body (2) and a cymbal piece (1). A hollow arc-shaped inner space (11) is cut in the reed (2), the outer portion of the inner space (11) is an outer ring region (13), and the inner portion (11) is inner portion The disc (14) is additionally hollowed out at the notch of the inner hollow region (11), and two retaining holes (15) are arranged at opposite ends of the retaining groove (12) on the reed (1). . a piston body (2), a valve head (23) is arranged at the upper end, a piston rod (21) is extended under the valve head (23), and a shaft hole (22) is arranged at the lower end of the piston rod (21); the valve head (23) There is a passage (28) at the center to allow air to flow from below the passage (28) to the top of the valve head (23); the top surface (24) of the valve head (23) is provided with two screw holes (25). The bolt (16) is fixed in the screw hole (25) through the positioning hole (15) of the reed (1); a stopper (29) is stood at the other end of the top surface (24) of the valve head (23). The moving block Q9) is an inverted L-shaped bump that extends through the retaining groove (12) of the reed (1), so that the reed (1) is limited in vibration, and the amplitude is not too large and causes too much sound. φ The second figure is a side view of the invention. It can be seen from the figure that the positioning hole (15) at one end of the reed (1) is locked by the bolt (16). When the reed (1) is cleaved by the air, the reed (1) is stopped at the other end (12). ) can move up and down until the stop groove (I2) is resisted by the stop block (29), and the inner piece (14) is slightly bent upwards, at which time the air can be between the reed (1) and the top surface (24). The gap overflows. The third and fourth figures are the second embodiment of the present invention. The reed (3) is only provided with two positioning holes (31) and a stopping groove (32). There is no inner space (11) of the previous embodiment, and the two positioning holes (31) are locked by screws (36). On the screw hole (25). An inverted l-shaped stop block (29) is erected on the other end of the top surface (24) of the valve head (23), and extends through the cymbal piece 200831784 to cause the yellow piece (3) to be limited in vibration.
