Embodiment 1

[0042] Such as Figure 4 As shown, this embodiment provides a compressor cylinder 1, which is especially suitable for rotary compressors. The cylinder 1 is provided with a slide groove 11 radially on the wall of the cylinder 1, and a spring hole 12 communicating with the slide groove 11 is arranged on the radially outer side of the slide groove 11. The tail of the spring hole 12 is The end is the closed end 121 formed by the wall of the cylinder 1; the spring hole 12 is provided with a spring installation guide port 13 communicating with the spring hole 12 on at least one side of the cylinder 1 wall on both sides of the cylinder 1 axial direction. .

[0043] By setting the tail end of the spring hole 12 as the closed end 121 formed by the wall of the cylinder 1, it prevents the sliding plate spring 3 from being pushed out of the spring hole 12 by the sliding plate 2 during work, which is beneficial to ensure the reliability of the compressor. At the same time, the noise insi...

Embodiment 2

[0048] This embodiment provides a fixing structure for the sliding leaf spring 3 , including the cylinder 1 , the sliding leaf 2 and the sliding leaf spring 3 in the first embodiment. Wherein, the slider 2 is reciprocally slidably arranged in the slider groove 11 of the cylinder 1, the slider spring 3 is arranged in the spring hole 12 of the cylinder 1, one end is connected to the tail of the slider 2, and the other end is connected to the tail of the slider 2. One end abuts against the closed end 121 of the spring hole 12 .

Embodiment 3

[0050] This embodiment provides a rotary compressor, including a closed casing, a motor assembly and a compression pump body arranged in the closed casing, a gas-liquid separator communicated with the compression pump body in the compressor through an intake pipe, and a gas-liquid separator in the closed casing The upper end is provided with an exhaust pipe. The motor assembly of the compressor includes a stator and a rotor, and the compressor shaft is driven to rotate by the rotor. The compression pump body includes an upper flange 5, a cylinder 1 and a lower flange 6 which are sequentially installed along the axial direction of the compressor shaft. The cylinder 1 in this embodiment is the cylinder 1 in the first embodiment. The cylinder 1 is equipped with a roller installed on the eccentric part of the compressor shaft. When the compressor shaft rotates, the roller is driven to roll along the inner wall of the cylinder 1. The intake pipe communicates with the inner cavity ...

Abstract

The invention provides an air cylinder, a slip sheet spring fixing structure and a rotary compressor. The air cylinder is provided with a slip sheet groove which is formed in the wall of the air cylinder in the radial direction. The radial outer side of the slip sheet groove is provided with a spring hole communicating with the slip sheet groove. The tail end of the spring hole is a sealed end formed by the wall of the air cylinder. A spring installation guiding opening communicating with the spring hole is formed in the spring hole along at least one of the two air cylinder side walls in the axial direction of the air cylinder. By arranging the tail end of the spring hole to be the sealed end composed of the wall of the air cylinder, the situation that a slip sheet spring is ejected out of the spring hole by a slip sheet during working is prevented, and the work reliability of the compressor is ensured; and meanwhile, the situation that noise in a compressor pump body is transmitted to a shell body and the outside through the spring, namely, noise outleakage occurs, is avoided. Moreover, according to the air cylinder, the slip sheet spring fixing structure and the rotary compressor, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a cylinder, a vane spring fixing structure and a rotary compressor. Background technique [0002] In order to form a pressure difference when the rotary compressor is started, the arc surface of the sliding vane needs to be in contact with the rolling piston to separate the cylinder into an exhaust chamber and an air suction chamber. Add slide spring to make the slide against the roller. The traditional way of fixing the vane spring basically adopts the way that the tail of the spring is closely matched with the spring hole, such as Figure 1-3 As shown, the spring hole is set on the radially outer side of the cylinder wall. When installing, the slide spring is inserted into the spring hole from the outside, and fixed by the interference fit between the outer diameter of the spring tail and the inner diameter of the cylinder slide spring hole. The disadvantage of this spring...
