Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the cylinder and the compressor of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] like figure 1 , 2 , Shown in 3, a kind of cylinder 1, threaded through hole 2 is set on the cylinder 1;

[0030] The threaded through hole 2 includes a first internal oblique threaded hole 3, a second internal oblique threaded hole 4 and a straight threaded hole 11;

[0031] Internal oblique threaded hole is a threaded hole with tapered inner hole.

[0032] The first internally oblique threaded hole 3 and the second internally obliquely threaded hole 4 are arranged at both ends of the threaded through hole 2 respectively, and are connected by a straight ...

Abstract

The invention provides a cylinder and a compressor. The cylinder is provided with threaded through holes; the threaded through holes comprise a first internal oblique threaded hole, a second internal oblique threaded hole and a straight threaded hole; the first internal oblique threaded hole and the second internal oblique threaded hole are respectively arranged at two ends of the threaded through holes and are connected with the straight threaded hole; a first external screw sequentially passes through the first internal oblique threaded hole and the straight threaded hole, then is mounted on the cylinder a threaded connection mode, and is used for fixing an external upper flange and a muffler on the cylinder; and a second external screw sequentially passes through the second internal oblique threaded hole and the straight threaded hole, is mounted on the cylinder is a threaded connection mode, and is used for fixing an external lower flange on the cylinder. The cylinder has the advantages of low cost, simple structure and mounting convenience, can improve the uneven load distribution of screw teeth, reduces the deformation of internal holes of the cylinder fastened by the flanges, and effectively prevents the unsmooth running even clamping phenomenon of a pump body in order to make the compressor run reliably.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to 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 the screws and the cylinder were d...
