Problems solved by technology

[0006] The object of the present invention is to provide a screw mounting structure for a cylinder and a compressor. The structure is simple and easy to install, which can improve the uneven load distribution of the screw teeth, reduce the deformation of the cylinder inner hole after the flange is fastened, and effectively prevent the pump The body is not moving smoothly or even stuck

Embodiment approach

[0034] As a possible embodiment, the mounting hole 3 is provided with an internal thread 10 in the mounting hole;

[0035] The screw sleeve 1 includes a screw sleeve external thread 9;

[0036] The external thread 9 of the screw sleeve is compatible with the internal thread 10 of the mounting hole;

[0037] The screw sleeve 1 is fixedly installed in the installation hole 3 through the screw sleeve external thread 9 in a threaded manner.

[0038] Installing the threaded sleeve 1 into the installation hole 3 through threaded connection is not only easy to operate, but also ensures that the screw sleeve 1 is reliably fixed in the installation hole 3 .

[0039] As a possible implementation manner, the internal thread 8 of the screw sleeve and the external thread 9 of the screw sleeve are concentric bodies.

[0040] Since the stress on the screw 2 acts on the inner threaded hole 8 of the screw sleeve, and the reverse stress generated by the inner thread 10 of the installation hol...

Abstract

The invention provides a cylinder screw mounting structure and a compressor. The cylinder screw mounting structure comprises a screw sleeve and a screw, and an installing hole arranged in a cylinder; the screw sleeve is fixedly arranged in the installing hole; the screw sleeve is provided with screw sleeve internal screw threads; the screw is connected with the screw sleeve internal screw threads via threaded connection so as to realizing fixed arrangement of an external upper flange, an external lower flange, and an external muffler onto the cylinder. The cylinder screw mounting structure possesses following advantages: cost is low; structure is simple; installation is convenient; nonuniform screw tooth loading distribution is improved; deformation of cylinder inner holes after flange tightening is improved; unsmooth operation and even blocking of a pump body are avoided; and operation reliability of the compressor is increased.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a screw installation structure of a cylinder and a compressor. Background technique [0002] With the continuous development of society and the continuous improvement of people's living standards, air conditioners have become one of the most important electrical appliances in people's lives. [0003] At present, the assembly of the pump body of the compressor in the air conditioner is to use screws to connect the upper muffler and the upper flange to the cylinder and center it, then put in the crankshaft, rollers and slides, check the clearance with plugs, and then use screws to Attach and center the lower flange to the cylinder. When the lower flange is connected to the cylinder by screws, the screws need to be tightened with a certain torque. After tightening, the pump body often runs poorly or even stuck. After investigation, it was found that the stiffness and deformation of ...
