Embodiment 1

[0033] In such figure 1 In the illustrated 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. The connecting rod is provided with a speed regulating chute 5. The speed regulating chute is a straight groove, and the length of the speed regulating chute and the connecting rod is Inclined setting, the inclination direction of the speed control chute is consistent with the direction of crankshaft rotation (see figure 2 , The arrow in the figure is the direction of rotation of the crank on the crankshaft), the speed control chute crosses the center line in the length direction of the connecting rod, and the speed control chutes on both sides of the c...

Embodiment 2

[0035] Example 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 butting two arc-shaped grooves with a centrally symmetric structure (see Picture 10 ), the connection between the head and tail ends of the speed control chute and the length of the connecting rod are arranged obliquely, the inclination direction of the speed control chute is consistent with the direction of crankshaft rotation on the crankshaft, and the rest is the same as the first embodiment.

Embodiment 3

[0037] In the third embodiment, the connecting rod and the piston are an integral structure, and the rest is the same as in the first embodiment.

Abstract

The invention discloses a compressor structure which comprises a crank and at least one cylinder arranged on the radial direction of the crank and driven by the crank. A piston of the cylinder is provided with a connecting rod fixed with the piston, the connecting rod is provided with a speed regulation sliding groove, the length of the speed regulation sliding groove in the transverse direction of the connecting rod is matched with the rotary diameter of a crank throw on the crank, and the crank throw on the crank is connected to the inner side of the speed regulation sliding groove in a sliding mode. The compressor structure effectively solves the problems that operation of a compressor in the prior art is imbalanced, and the noise is loud, and is stable in operation, low in noise, long in service life and suitable for various types of compressors.

Description

Technical field [0001] The invention relates to a compressor, in particular to an improved low-noise compressor structure. Background technique [0002] Compressors in the prior art widely use a crankshaft connecting rod mechanism, and the crankshaft rotates through a swinging connecting rod to drive the piston to reciprocate, thereby completing the compressor function. However, when the piston of this structure reciprocates, the rotation angle of the crankshaft is not proportional to the displacement of the piston. When the piston is close to the top and bottom dead center, the angle of the crankshaft is relatively large and the displacement of the piston is small. Under the condition that the crankshaft rotates at a constant angular velocity, the piston is a cycle of acceleration-deceleration-acceleration-deceleration. In this working mode, one is that the output torque of the motor is large and sometimes small, and the second is that the movement of the piston is fast and som...
