Embodiment 1

[0034] in such as figure 1 In the shown embodiment 1, a compressor structure includes a body 1, a crankshaft 6 and a cylinder arranged in the radial direction of the crankshaft and driven by the crankshaft. The piston 3 is arranged in cooperation with the piston hole 2 on the body, and the piston is provided with There is a connecting rod 4 fixed to the piston. The fixed end 11 of the connecting rod is crimped with the piston. Inclined setting, the inclination direction of the speed regulating chute is consistent with the rotation direction of the crank throw on the crankshaft (see figure 2 , the arrow in the figure is the rotation direction of the crank throw on the crankshaft), the speed regulating chute crosses the center line in the length direction of the connecting rod transversely, and the speed regulating chute on both sides of the center line forms a centrosymmetric structure (see Figure 9 ). An oil passage 8 is provided on the length direction of the connecting r...

Embodiment 2

[0036] Embodiment 2 The connecting rod and the piston are in a screw connection structure, the speed regulating chute on the connecting rod is S-shaped, and the S-shaped speed regulating chute is formed by the butt joint of two arc-shaped grooves with a center-symmetrical structure (see Figure 10 ), the connecting line at the first and last ends of the speed regulating chute is inclined to the length direction of the connecting rod, and the inclination direction of the speed regulating chute is consistent with the direction of rotation of the crank throw on the crankshaft.

Embodiment 3

[0038] Embodiment 3 The connecting rod and the piston have an integral structure, and the rest are the same as in Embodiment 1.

Abstract

The invention discloses a compressor structure which comprises a crankshaft and at least one cylinder arranged in the radial direction of the crankshaft and driven by the crankshaft. A connecting rod fixed to a piston is arranged on the piston of each cylinder, a speed-adjusting sliding groove is formed in each connecting rod, length of each speed-adjusting sliding groove in the transverse direction of the corresponding connecting rod is matched with rotating diameter of a crank on the crankshaft, and the crank on the crankshaft is slidably connected in the speed-adjusting sliding groove. By the compressor structure, the problem that compressors are unbalanced in working and high in noise in the prior art is solved. The compressor structure is stable in working, low in noise, long in service life and suitable for various compressors different in type.

Description

[0001] This patent application is a divisional application of the patent application with the application number 201210418501.2, the application date is October 29, 2012, and the invention title is "a compressor structure". technical field [0002] The invention relates to a compressor, in particular to an improved low-noise compressor structure. Background technique [0003] The compressors in the prior art widely adopt the crankshaft-connecting-rod mechanism, and the crankshaft rotates to drive the piston to reciprocate through the swinging connecting rod, thereby completing the function of the compressor. But when the piston of this structure reciprocates, the angle of rotation of the crankshaft is not proportional to the displacement of the piston. When the piston is close to the upper and lower dead centers, the angle of rotation of the crankshaft is relatively large and the displacement of the piston is very small. Under the condition that the crankshaft rotates at a c...
