Therefore, major automobile manufacturers are all concerned about the vibration, noise and comfort of automobiles.

[0003] For example, a cylinder block for an inclined plate type piston compressor with the authorization announcement number of "CN220646141U" solves the problem that for the existing cylinder block of an inclined plate type piston compressor, after the compressor works for a long time, the cylinder block will be deformed, which will directly affect the self-noise of the compressor and ultimately affect the normal operation of the compressor in the air conditioning system. The above problem of cylinder block deformation caused by the insufficient strength of the bolt hole thickness is solved, and thus the self-noise of the compressor is reduced. Considering the existing cylinder block of an inclined plate type piston compressor, the length of the reinforcing bolt is increased to enhance firmness. However, the length of the bolt is too long and enters the inside of the cylinder wall, changing the thickness of the internal structure of the steel body itself, resulting in the noise generated by vibration still being transmitted outward without reduction, affecting the comfort of use. Content of the Utility Model

The inner wall of the reinforcement sleeve is processed with a threaded hole. The inner wall of the threaded hole is threadedly connected with a fixing bolt. The outer wall of the fixing bolt abuts against the front cylinder head.

[0007] Preferably, the outer wall of the piston cylinder is fixedly connected with a second connecting frame. The outer wall of the second connecting frame is fixedly connected with a main shaft cylinder. The inner wall of the cylinder wall is connected with an installation mechanism.

[0008] Preferably, the installation mechanism includes a partition plate, the outer wall of the partition plate is fixedly connected to the cylinder wall, the outer wall of the partition plate is fixedly connected to a bearing, and an installation cylinder is installed on the inner wall of the bearing.

[0009] Preferably, the inner wall of the piston hole is slidably connected to the piston, the end of the piston is fixedly connected to the movable frame, and the inner wall of the movable frame is movably connected to the swash plate.

[0010] Preferably, the inner wall of the cylinder wall is fixedly connected to a slide bar, the outer wall of the slide bar is slidably connected to the movable frame, and a rear cylinder head is installed on the outer wall of the cylinder wall.

[0011] The cylinder block for a swash plate piston compressor proposed by the present utility model has the beneficial effects that: by restricting the movement range of the movable frame in the cylinder wall through the slide bar inside the cylinder wall, the movements generated by the movable frame will not affect each other, and the first connecting frame and the second connecting frame divide multiple piston cylinders into regions, so that the vibration generated inside each piston cylinder will not be directly transmitted to the media in other parts, reducing the vibration, and can achieve the effect of reducing noise inside the work.

[0019] The present utility model will be further described below in conjunction with the accompanying drawings:

[0020] Embodiment 1:

[0021] Please refer to Figures 1-6 : In this embodiment, a cylinder block for an inclined plate type piston compressor includes a cylinder wall 1 and an arc groove 2. The inner wall of the cylinder wall 1 is processed with the arc groove 2. The inner wall of the cylinder wall 1 is fixedly connected with a first connecting frame 3. The outer wall of the first connecting frame 3 is fixedly connected with a piston cylinder 4. The inner wall of the piston cylinder 4 is processed with a piston hole 5. The outer wall of the cylinder wall 1 is connected with a reinforcement mechanism 6.

[0022] The reinforcement mechanism 6 includes a reinforcement sleeve 601. The piston cylinder 4 inside the cylinder wall 1 is reinforced and wrapped again around the working area, so that the working state of the piston cylinder 4 and the cylinder wall 1 can be strengthened. The inner wall of the reinforcement sleeve 601 is fixedly connected with the cylinder wall 1. The inner wall of the reinforcement sleeve 601 is processed with a threaded hole 602. The inner wall of the threaded hole 602 is threadedly connected with a fixing bolt 603. The outer wall of the fixing bolt 603 abuts against the front cylinder head 604;

[0023] The slide bar 13 inside the cylinder wall 1 restricts the movement range of the movable frame 11 in the cylinder wall 1, so that the movable frames 11 generated do not affect each other. In addition, the first connecting frame 3 and the second connecting frame 7 divide multiple piston cylinders 4 into areas, so that the vibration generated by the movement inside each piston cylinder 4 will not be directly transmitted to the media in other parts, reducing the vibration, and can play the effect of noise reduction during internal work. The reinforcement sleeve 601 isolates the outside of the piston cylinder 4 of the cylinder wall 1, and reduces the noise transmitted outward by the vibration to the minimum, improving the comfort of use.

[0024] The outer wall of the piston cylinder 4 is fixedly connected with the second connecting frame 7. The outer wall of the second connecting frame 7 is fixedly connected with the main shaft cylinder 8. The inner wall of the cylinder wall 1 is connected with an installation mechanism 9. Through the connection between the bearing 902 on the partition plate 901 and the installation cylinder 903, the installation cylinder 603 is restricted in position with the external installation components. The installation mechanism 9 includes a partition plate 901. The outer wall of the partition plate 901 is fixedly connected with the cylinder wall 1. The outer wall of the partition plate 901 is fixedly connected with the bearing 902. The inner wall of the bearing 902 is installed with an installation cylinder 903.

[0025] Working principle:

[0026] Working stage

[0027] An external main shaft passes through the mounting cylinder 903 and the main shaft cylinder 8, so that the outer wall of the external main shaft is in tight contact with the swash plate 12 inside the cylinder wall. The external main shaft drives the swash plate 12 to rotate. The slope generated by the rotation of the swash plate will cause the movable frame 903 to slide reciprocally on the slide bar 13. The movable frame 903 will drive the piston 10 to perform reciprocating piston motion in the piston hole 5 inside the piston cylinder 4. At the same time, the mounting cylinder 903 will rotate driven by the bearing 902. The first connecting frame 3 and the second connecting frame 7 are used to divide the multiple piston cylinders 4 into regions, so that the vibration generated by the motion inside each piston cylinder 4 will not be directly transmitted to the media in other parts, reducing the vibration and achieving the effect of noise reduction during internal work. At the same time, the reinforcing sleeve 601 wraps the piston cylinder 4 of the cylinder wall 1, making the work inside the cylinder wall 1 and the piston cylinder 4 more stable and safe.

[0028] Embodiment 2:

[0029] Please refer to Figures 1-5 : In this embodiment, the inner wall of the piston hole 5 is slidably connected to the piston 10. The end of the piston 10 is fixedly connected to the movable frame 11. The inner wall of the movable frame 11 is movably connected to the swash plate 12. The inner wall of the cylinder wall 1 is fixedly connected to the slide bar 13. The outer wall of the slide bar 13 is slidably connected to the movable frame 11. The rear cylinder head 14 is installed on the outer wall of the cylinder wall 1.

[0030] Working principle:

[0031] By restricting the movement range of the movable frame 11 on the cylinder wall 1 through the slide bar 13 inside the cylinder wall 1, the movements generated by the movable frame 11 will not affect each other. At the same time, the rear end cover 14 on the cylinder wall 1 is disassembled, exposing the bearing 902 on the movable frame 11. Without affecting the piston cylinder 4 part at the front end of the cylinder wall 1, the bearing 902 can be maintained and replaced.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
