Abstract
The invention discloses a buffer piston structure of a compressor. The buffer piston structure of the compressor comprises a piston body, and a crankshaft connecting rod connected with the piston body, wherein a buffer through hole is formed inside the piston body; a piston barrel is arranged inside the buffer through hole; the crankshaft connecting rod is hinged at one end of the piston barrel. Compared with the prior art, the buffer piston structure of the compressor has the advantages as follows: a built-in piston is arranged inside an ordinary piston, the built-in piston is hinged with a crankshaft, and the crankshaft drives the built-in piston first and then drags the external piston to move through a traction buffer device connected with the external piston, so that when a check valve of the compressor intakes and exhausts gas, a buffer effect is achieved, thereby avoiding an instantaneous relatively-high pressure and reducing wear and tear of mechanical equipment.
Description
Technical field
The present invention relates to a kind of compressor buffer piston structure.
Background technique
On general piston type air compressor equipment, piston directly compresses, moment forms larger pressure, one-way valve on air compressor can be opened or closed by moment, the part that acts on switch valve in one-way valve is subject to for a long time the immense pressure of moment and easily damages, and each pipe joint place of device interior also can be become flexible and break because of the immense pressure of this moment.
Summary of the invention
The technical issues that need to address of the present invention are for above-mentioned the deficiencies in the prior art, and provide a kind of can avoid piston compared with large pressure and the compressor buffer piston structure of damage equipment part.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of compressor buffer piston structure, comprises piston only, and connects the crankshaft-link rod of piston only, and buffering through hole is set in piston only, in buffering through hole, piston cylinder is set, and crankshaft-link rod is hinged on piston cylinder one end.
In buffering through hole, arrange and be greater than the inner hole structure that cushions through-hole diameter, the ring-shaped step contacting with inner hole structure inner wall sealing is set in the piston cylinder part in inner hole structure, the spring assembly being connected with inner hole structure interior edge face is set respectively on two end faces of ring-shaped step.
The length of described piston cylinder is less than the length of piston only.
Compared with prior art, a kind of compressor buffer piston structure of the present invention, utilize the preposition motion of piston cylinder in piston only, produce less pressure in advance each part in compressor apparatus, again by piston cylinder traction piston only, realize the compression of larger pressure and carry out work, a cushion effect is provided to inner each part of compressor apparatus, avoid the immense pressure damage equipment part of moment, protected equipment, simple in structure, applicability is wide, can be used in oil pump, on the equipment such as air pump; In buffering through hole, inner hole structure is set, ring-shaped step is set on piston cylinder, ring-shaped step and inner hole structure interior edge face are provided with spring assembly, have so just limited the sphere of activities of piston cylinder in piston only, the effect that spring assembly provides extruding to slow down and draw; The length of piston cylinder is less than the length of piston only, prevents piston cylinder percussion piston cylinder after being extruded.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention;
Wherein, 1-piston only, 2-crankshaft-link rod, 3-cushions through hole, 4-piston cylinder, 5-inner hole structure, 6-ring-shaped step.
Embodiment
Describe the preferred technical solution of the present invention in detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of compressor buffer piston structure of the present invention, comprises piston only 1, and the crankshaft-link rod 2 of connection piston only 1, at the interior buffering through hole 3 that arranges of piston only 1, at the interior piston cylinder 4 that arranges of buffering through hole 3, crankshaft-link rod 2 is hinged on piston cylinder 4 one end.
Be greater than the inner hole structure 5 of buffering through hole 3 diameters in the interior setting of buffering through hole 3, the ring-shaped step 6 contacting with inner hole structure 5 inner wall sealings is set in piston cylinder 4 parts in inner hole structure 5, the spring assembly being connected with inner hole structure 5 interior edge faces is set respectively on two end faces of ring-shaped step 6.
The length of described piston cylinder 4 is less than the length of piston only 1.
