[0002] At present, reciprocating compressors are widely used. An intermediate cylinder is provided inside the compressor. The patent publication number CN204532755U provides a one-piece middle body and cylinder structure of a compressor, which solves the problems of the existing split middle body and cylinder with insecure connection, easy loosening and leakage, large occupied layout space, and time-consuming and inefficient installation and disassembly. It includes a straight cylinder-shaped connecting body formed by integrally casting a middle body housing and a cylinder housing. A connecting flange on the machine body side is arranged on the outer end surface of the middle body, and a connecting flange on the cylinder side is arranged on the outer end surface of the cylinder. A partition chamber is formed inside the connecting body. A disassembly and assembly window for disassembling and assembling internal components is arranged on the side wall of the connecting body. A plurality of reinforcing ribs are arranged on the outer wall of the connecting body along the extending direction of the connecting body, and a lifting hole is arranged on the reinforcing ribs.

[0003] However, there are certain problems with this intermediate cylinder. Since it is changed to a square cylinder structure, although the internal space is expanded, which is convenient for installation, replacement, maintenance and detection, in the actual use process, the four top corners of the square cylinder are more likely to be stressed and deformed, resulting in the deformation of the square cylinder, and further affecting the operation of the internal components. Therefore, there are certain problems with this square cylinder. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Embodiment 1

[0021] As Figures 1 to 4 shown, an intermediate connecting cylinder of a compressor in the first aspect embodiment of the present utility model includes a square cylinder 1. Flange plates 2 and fixed plates 3 are respectively fixedly installed at the front and rear ends of the square cylinder 1. Impact-resistant components 4 are fixedly installed at the four corners of the square cylinder 1. The impact-resistant component 4 includes a right-angle pad 401. A first support leg 402 is fixedly installed at the left end of the right-angle pad 401. A fixing plate 403 is fixedly installed inside the right-angle pad 401. Threaded holes 4031 are formed on the surface of the fixing plate 403. Bolts 404 are threadedly installed inside the threaded holes 4031. The bottom ends of the bolts 404 are threadedly installed inside the square cylinder 1. Four threaded grooves are formed on the outside of the square cylinder 1. The positions and sizes of the four threaded grooves correspond to the bolts 404. The number of the right-angle pads 401 is eight. The eight right-angle pads 401 are equally divided into four groups. The number of the first support legs 402 is three. Contact pads 4021 are fixedly installed at the bottom ends of the three first support legs 402. The bottom ends of the contact pads 4021 are attached to the outer surface of the square cylinder 1.

[0022] In the above embodiment, it should be noted that the square cylinder 1, the flange plate 2, and the fixed plate 3 are all existing components in a compressor integrated middle body and connecting cylinder structure provided in the patent publication number CN204532755U of the comparative document, with the same functions and structures, so no further elaboration will be made.

[0023] The technical effects achieved by the above embodiment are as follows: The rounded corner structure of the right-angle pad 401 can effectively transmit the impact force received by the first support leg 402 and the second support leg 407, and then use the arc to eliminate stress, thereby preventing the square structure of the square cylinder 1 from being damaged by stress. And using the right-angle pad 401 itself having a certain thickness to make it have the ability to resist impact, thereby preventing the outer wall top corner of the square cylinder 1 from being directly contacted by an object to generate impact deformation, further protecting the overall device.

[0024] Embodiment 2

[0025] As Figure 1 and Figure 3As shown in the figure, an intermediate cylinder of a compressor includes all the contents of Embodiment 1. In addition, a second support leg 407 is fixedly installed at the bottom end of the right-angle pad 401, and the side surface of the bottom end of the second support leg 407 is fixedly attached to the outer wall of the square cylinder 1. The outer end of the right-angle pad 401 is provided with a rounded corner structure. A guide rod 405 and a sleeve 406 are respectively and fixedly installed inside each group of right-angle pads 401, and the guide rod 405 and the sleeve 406 are sleeved with each other. The fixing plates 403 inside each group of right-angle pads 401 are staggeredly installed.

[0026] The technical effects achieved by the above embodiment are as follows: The fixing plate 403 and the square cylinder 1 are fixed by bolts 404, so that the entire right-angle pad 401 can be attached to the outside of the square cylinder 1, making it have the ability to be disassembled and assembled. In addition, the sleeving of the guide rod 405 and the sleeve 406 is beneficial for the positioning connection of the two right-angle pads 401 and can also ensure that the two do not shift, preventing the outer edge of the right-angle pad 401 from not fitting at the top corner of the square cylinder 1, and further improving the fixing ability of their fitting. <s

[0027] Working principle: The two right-angle pads 401 are sleeved and connected through the guide rod 405 and the sleeve 406, and then the bolts 404 are threadedly fixed inside the corresponding threaded grooves on the surface of the square cylinder 1 through the two fixing plates 403. Then, the first support leg 402 and the second support leg 407 are attached to the outer wall of the square cylinder 1. Finally, the fitting and fixing of the right-angle pad 401 are completed to protect the top corner of the square cylinder 1. When the square cylinder 1 vibrates, the internal stress is transmitted from the edge to the corner and finally transmitted to the inside of the right-angle pad 401 for release, reducing the loss of the square cylinder 1 itself.
