Embodiment 1

[0039] Such as Figure 1-3 Shown, the present invention provides a kind of cylinder structure, it comprises:

[0040] Cylinder body 1;

[0041] There is at least one mounting hole, which is arranged on the cylinder body 1 and is used to cooperate with threaded connectors (preferably screws) (to install the cylinder, upper flange, lower flange, etc.); and in the mounting hole At least one hole diameter is larger than the outer diameter of the threaded connector, forming an assembly hole 2;

[0042] The sealing part 3 can be fitted into the fitting hole 2, and the threaded connector can be inserted into the inside of the sealing part 3 and mated with it.

[0043] By setting the sealing part, fitting it into the assembly hole, and making the diameter of the assembly hole larger than the threaded connector, and the threaded connector is inserted into the sealing part to connect with it, the threaded connector can be removed during the assembly process of the pump body assembly o...

Embodiment 2

[0057] Such as Figure 4-6 As shown, this embodiment changes the number of mounting holes on the basis of Embodiment 1. The cylinder structure also includes a slide slot 4. In the installation hole, the Mounting holes are processed into the mounting holes 2 , and the rest of the mounting holes are processed into threaded holes 5 . In the cylinder structure of the present invention, the light holes are processed at the screw holes on both sides of the traditional cylinder near the slide groove, and then the seals processed with threaded holes are inserted into the light holes (the seals are iron hibiscus, which are equal to the cylinder, and the The threaded hole size on the cylinder is exactly the same as the original threaded hole size of the cylinder). Assembly is done by mating the screw in the threaded hole on the seal.

[0058] 1. During the assembly process of the pump body components of the compressor, the threaded part of the screw cooperates with the seal, which doe...

Embodiment approach 1

[0060] The first embodiment is that all the screw holes on the cylinder are improved, which can reduce the deformation of the inner wall of the cylinder and the inner wall of the slide groove at the same time. In the second embodiment, only the two screw holes on both sides of the slide groove are improved, so that the deformation of the inner wall of the slide groove is improved, but the deformation of the inner wall of the cylinder is not greatly improved. Generally, if the deformation of the inner wall of the cylinder is not large, no serious consequences will be caused, but the deformation of the slide groove can easily cause the slide to be stuck, or there will be a slide sound during operation, and the noise is abnormal.

[0061] Preferably,

[0062] The threaded connector can be inserted into the threaded hole 5 , and the external thread of the threaded connector is mated with the internal thread of the threaded hole 5 . In this way, the direct threaded connection betw...

Abstract

The invention provides an air cylinder structure, a compressor and an air conditioner. The air cylinder structure comprises an air cylinder body (1), at least one mounting hole and sealing parts (3).The mounting holes are formed in the air cylinder body and used for being connected with threaded fasteners in a matched mode. The diameter of at least one in the mounting holes is larger than the outer diameters of the threaded fasteners to form assembly holes (2). The sealing parts (3) can be assembled into the assembly holes (2), and the threaded fasteners can be inserted into the sealing parts(3) and connected with the sealing parts (3) in a matched mode. In the assembly process of pump body assemblies of the compressor, the threaded parts of the threaded fasteners are matched with the sealing parts, so that assembly is not affected, meanwhile deformation caused by pre-tightening force mainly occurs to the sealing parts with the small hardness and enables the sealing parts and the assembly holes to be completely attached and sealed, deformation, caused by the pre-tightening force, of the inner walls of an air cylinder and a slide piece groove can also be reduced, friction betweenthe inner wall of the air cylinder and a roller is reduced, and meanwhile a slide piece is prevented from being jammed.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a cylinder structure, a compressor and an air conditioner. Background technique [0002] In the prior art, during the assembly process of the compressor pump body assembly, screw connections are often used between the various parts. Before assembly, light holes are directly processed on the upper and lower flanges, and threaded holes are processed at the corresponding positions of the cylinder, and then the cylinder and the upper and lower flanges are assembled together with screws. The head of the screw is in contact with the upper and lower flanges, and the threaded part is matched with the threaded hole of the cylinder). [0003] During this process, the pre-tightening force applied to the screw will also cause the cylinder to be squeezed and deformed while compressing the upper flange (or lower flange) and the cylinder, which in turn will cause the threaded p...
