Embodiment Construction

[0026] The present invention is an improvement in the structure of the piston body 2 . Please refer to FIG. 1 , the present invention includes a piston body 2 and a reed 1 . Cut a hollow circular arc-shaped inner hollow area 11 in the reed 2, the peripheral part of the inner hollow area 11 is an outer ring area 13, and the inner peripheral part of the inner hollow area 11 is an inner disc 14, and the inner circle of the inner hollow area 11 A stop groove 12 is hollowed out at the notch, and two positioning holes 15 are set at the opposite ends of the stop groove 12 on the reed 1 .

[0027] One piston body 2, the upper end is provided with valve head 23, and valve head 23 extends piston rod 21, and piston rod 21 lower end is provided with a shaft hole 22; Above the valve head 23; the top surface 24 of the valve head 23 is provided with two screw holes 25, which can be fixed in the screw holes 25 through the positioning holes 15 of the aforementioned reed 1 with bolts 16; the o...

Abstract

The present invention discloses piston bodies construct improvement of air compressor, especially is a construct improvement design on top spring of piston body. On top of valve head of piston body has a reed which has an arc inner gap. The reed has two parts of outer ring section and inner disc. Gas pushes reed upward to come out from gap. Both outer ring section and inner disc are bending by applying force, so reed is easy bending and difficult to generate localized stress concentrated phenomenon forming crease mark at bending part. Reed has two locating hole, screw for fixing reed on valve head by bolt, and induction trunk for covering valve head with reed. A stop groove is placed on other head of reed. Stop blocks on valve head cross the stop groove. When piston body acts in air cylinder, reed has switching action to control gas in and out with the action of piston body. Because stop blocks can connect with stop groove to restrict swing of reed, produce of noise can be reduced. The construct of the design is a durable and quiet piston body construct with higher air inlet efficiency.

Description

technical field [0001] The invention relates to an air compressor, in particular to an improved piston body structure of the air compressor. Background technique [0002] In the piston body designed by the inventor in the past, a channel for ventilation is established under the valve head of the piston body, and a complete reed without cutting is established on the top surface of the valve head. One end of the reed is fixedly connected to the valve head, and the other end of the reed covers the channel. Keep air from entering the cylinder chamber. When the piston body reciprocates in the cylinder chamber, the gas pushes the reed and enters the cylinder chamber from the passage through the gap, or the reed closes to prevent the gas from passing through the passage, and the reed vibrates back and forth in a short time, which also causes metal fatigue. Phenomenon, the wrinkle phenomenon occurs at the connection between the reed and the valve head, causing damage. The inventor...
