Abstract
Description
Technical Field
[0001] This utility model belongs to the field of compressor technology, specifically relating to a compressor valve plate fixing mechanism. Background Technology
[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. It is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it, and discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle. During the operation of the compressor, the valve plate plays a crucial role. It controls the entry and exit channels of refrigerant or other working media, and its performance directly affects the efficiency, reliability, and service life of the compressor.
[0003] Current common compressor valve plate fixing methods have many shortcomings. Traditional fixing structures often rely solely on bolt and nut connections. Under the long-term, high-frequency vibration environment of the compressor, bolts are prone to loosening. Once the bolts loosen, the valve plate will shift, leading not only to refrigerant leakage and reduced cooling or compression efficiency, but also to collisions and friction between the valve plate and other components, damaging the valve plate and related parts, significantly increasing compressor maintenance costs and downtime. Moreover, existing fixing mechanisms lack high positioning accuracy when installing the valve plate, making it difficult to ensure precise alignment of the valve ports on the valve plate with the corresponding flow channels inside the compressor, which also affects the compressor's performance. In addition, while some complex fixing structures solve some of the above problems to a certain extent, they also suffer from high costs, cumbersome installation and disassembly, and are not conducive to large-scale production and subsequent maintenance. Utility Model Content
[0004] The purpose of this invention is to provide a compressor valve plate fixing mechanism that can solve the above-mentioned problems.
[0005] The specific technical solution adopted by this utility model is as follows:
[0006] A compressor valve plate fixing mechanism includes a mounting plate with a mounting upper plate movably connected to it. The mounting upper plate has a mounting through hole, and the compressor valve plate is mounted on the mounting upper plate through the mounting through hole with bolts. A quick-release assembly is provided between the mounting upper plate and the mounting plate.
[0007] Preferably, the mounting plate is divided into upper and lower layers, and the quick-release assembly includes a central shaft disposed at the bottom of the mounting plate. A circular insertion hole is provided at the center of the upper layer of the mounting plate, and the central shaft is located directly below the circular insertion hole.
[0008] Preferably, the quick-release assembly further includes a circular insert post disposed at the lower end of the mounting plate, the lower end of the circular insert post having a retaining ring, the sidewall of the retaining ring being inclined, the upper diameter of the retaining ring being larger than the diameter of the circular insert post, the longitudinal section of the retaining ring having a symmetrically distributed right-angled trapezoidal structure, and the circular insert post being compatible with the circular insertion hole and the central axis.
[0009] Preferably, the quick-release assembly further includes a pin movably disposed on the side of the mounting plate, the pin end having a locking block, the locking block having the same height as the circular post, the locking block having an inclined sidewall, the lower surface of the locking block being adapted to the upper surface of the retaining ring, and a spring connecting the locking block sidewall to the inner wall of the mounting plate.
[0010] Preferably, the mounting plate is symmetrically threaded with mounting bolts, the end of the pin is hinged with a pull ring, and the lower end of the locking block is movably connected with rollers at equal angle positions.
[0011] Preferably, the upper end of the mounting plate is provided with a circular positioning hole, and the mounting plate is provided with a positioning post that is compatible with the circular positioning hole.
[0012] The technical effects achieved by this utility model are as follows:
[0013] This utility model discloses a compressor valve plate fixing mechanism. By incorporating a quick-release assembly, a mounting plate can be quickly and securely installed onto a mounting U-shaped plate, thereby enabling the rapid installation of the compressor valve plate on the mounting U-shaped plate and its fixation in a designated position. This ensures both quick installation and quick removal of the compressor valve plate. When the mounting plate is placed downwards against the mounting U-shaped plate, the circular insert carrying the retaining ring passes precisely through the circular insertion hole. Simultaneously, the inner walls of the tubular circular insert and the retaining ring rest precisely on the outer wall of the central shaft, ensuring the accuracy of the compressor valve plate installation. As the circular insert carrying the retaining ring slides downwards through the circular insertion hole, the inclined side wall of the retaining ring presses against the side wall of the retaining block, causing the retaining block to slide laterally outwards. When the retaining ring has completely fallen to the bottom, the retaining ring... The inclined sidewalls no longer press against the sidewalls of the locking block. Under the action of the spring, the two pins move towards the center, the lower arm of the locking block fits against the upper arm of the retaining ring, and the lower apex of the locking block abuts against the circular post. The height of the locking block is aligned with the height of the circular post, thus defining the retaining ring. This completes the quick and easy installation of the upper plate onto the mounting plate. When the upper plate is quickly and easily installed onto the mounting plate, the positioning pin enters the circular positioning hole to prevent the upper plate from rotating relative to the mounting plate, while ensuring the accuracy of the compressor valve plate installation. When it is necessary to remove the compressor valve plate, pull the pins laterally to misalign the lower arm of the locking block with the upper arm of the retaining ring, and then pull out the upper plate directly to quickly remove the compressor valve plate. This ultimately achieves the quick installation or removal of the compressor valve plate while ensuring more precise installation accuracy. Attached Figure Description

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0020] like Figures 1-3 As shown, a compressor valve plate fixing mechanism includes a mounting plate 1, an upper mounting plate 2 movably connected to the mounting plate 1, an upper mounting plate 2 having a mounting through hole, and the compressor valve plate being mounted on the upper mounting plate 2 via bolts through the mounting through hole. A quick-release assembly 3 is provided between the upper mounting plate 2 and the mounting plate 1.
[0021] like Figures 1-3 As shown, in this utility model, by setting the quick-release assembly 3, the mounting plate 2 can be quickly and fixedly installed on the mounting plate 1, thereby realizing the quick installation of the compressor valve plate on the mounting plate 1 and fixing it in the designated position by the mounting plate 1, while ensuring the quick installation or quick disassembly of the compressor valve plate.
[0022] Preferably, the mounting plate 1 is divided into upper and lower layers, and the quick-release assembly 3 includes a central shaft 301 disposed at the bottom of the mounting plate 1. A circular insertion hole 302 is provided at the center of the upper layer of the mounting plate 1, and the central shaft 301 is located directly below the circular insertion hole 302.
[0023] like Figures 1-3As shown, in this utility model, the outer diameter of the central shaft 301 is smaller than the diameter of the circular insertion hole 302. By setting a U-shaped mounting plate 1 as a mounting base, the strength of the base is improved, making the installation of the compressor valve plate more stable.
[0024] Preferably, the quick-release assembly 3 further includes a circular insert 303 disposed at the lower end of the mounting plate 2. The lower end of the circular insert 303 is provided with a retaining ring 304. The retaining ring 304 has an inclined sidewall. The upper diameter of the retaining ring 304 is larger than the diameter of the circular insert 303. The longitudinal section of the retaining ring 304 has a symmetrically distributed right-angled trapezoidal structure. The circular insert 303 is compatible with the circular insertion hole 302 and the central shaft 301.
[0025] like Figures 1-3 As shown, in this utility model, the circular insert 303 has a tubular structure. When the mounting plate 2 is mounted downwards to fit the U-shaped plate 1, the circular insert 303 carrying the retaining ring 304 passes through the circular insertion hole 302. At the same time, the inner wall of the tubular circular insert 303 and the inner wall of the retaining ring 304 sit on the outer wall of the central shaft 301, ensuring the accuracy of the compressor valve plate installation.
[0026] Preferably, the quick-release assembly 3 further includes a pin 305 movably disposed on the side of the mounting plate 1, the end of the pin 305 is provided with a locking block 306, the height of the locking block 306 is the same as the height of the circular insert 303, the side wall of the locking block 306 is inclined, the lower surface of the locking block 306 is adapted to the upper surface of the retaining ring 304, and a spring 307 is connected between the side wall of the locking block 306 and the inner wall of the mounting plate 1.
[0027] like Figures 1-3 As shown, in this utility model, during the downward sliding process of the circular insert 303 carrying the retaining ring 304 through the circular insert 302, the inclined side wall of the retaining ring 304 presses against the side wall of the retaining block 306, causing the retaining block 306 to slide laterally outward. When the retaining ring 304 has completely fallen to the bottom, the inclined side wall of the retaining ring 304 just stops pressing against the side wall of the retaining block 306. Under the action of the spring 307, the two pins 305 move closer to the center, the lower arm of the retaining block 306 fits against the upper arm of the retaining ring 304, the lower apex of the retaining block 306 abuts against the circular insert 303, and the height of the retaining block 306 is aligned with the height of the circular insert 303, thus completing the restriction of the retaining ring 304 and completing the quick and easy fixing of the mounting plate 2 onto the mounting U-shaped plate 1.
[0028] Preferably, the mounting plate 1 is symmetrically threaded with mounting bolts 4, the end of the pin 305 is hinged with a pull ring 5, and the lower end of the locking block 306 is movably connected with a roller 308 at an equal angle position.
[0029] like Figures 1-3As shown, in this utility model, the mounting plate 1 is installed as a base at a designated position by mounting bolt 4, the pull ring 5 is provided to facilitate the horizontal pulling of the pin 305, and the roller 308 is provided to facilitate the horizontal sliding of the locking block 306.
[0030] like Figures 1-3 As shown, when it is necessary to disassemble the compressor valve plate, pull the pin 305 horizontally to make the lower arm of the locking block 306 and the upper arm of the locking ring 304 misaligned, and then pull out the mounting plate 2 directly to complete the quick disassembly of the compressor valve plate.
[0031] Preferably, the upper end of the mounting plate 1 is provided with a circular positioning hole, and the mounting plate 2 is provided with a positioning post 6 that is compatible with the circular positioning hole. In actual use, when the mounting plate 2 is quickly fixed on the mounting plate 1, the positioning post 6 enters the circular positioning hole to prevent the mounting plate 2 from rotating relative to the mounting plate 1, while ensuring the accuracy of the compressor valve plate installation.
[0032] like Figures 1-3As shown, the working principle of this utility model is as follows: the compressor valve plate is installed on the mounting plate 2 through the mounting through hole and bolts. The mounting U-shaped plate 1 is installed at a designated position using the mounting bolts 4. By setting the quick-release assembly 3, the mounting plate 2 can be quickly fixedly installed on the mounting U-shaped plate 1, thereby realizing the quick installation of the compressor valve plate on the mounting U-shaped plate 1 and fixing it in the designated position by the mounting U-shaped plate 1. At the same time, it ensures the quick installation or quick removal of the compressor valve plate. When the mounting plate 2 is pressed downward against the mounting U-shaped plate 1, the circular insert 303 carrying the retaining ring 304 just passes through the circular insert hole 302. At the same time, the inner wall of the tubular circular insert 303 and the inner wall of the retaining ring 304 just sit on the outer wall of the central shaft 301, ensuring the accuracy of the compressor valve plate installation. During the downward sliding process of the circular insert 303 carrying the retaining ring 304 through the circular insert hole 302, the inclined side wall of the retaining ring 304 squeezes the retaining ring. The sidewall of block 306 allows the locking block 306 to slide laterally outward. When the retaining ring 304 has completely fallen to the bottom, the inclined sidewall of the retaining ring 304 no longer presses against the sidewall of the locking block 306. Under the action of the spring 307, the two pins 305 move towards the center, the lower arm of the locking block 306 fits against the upper arm of the retaining ring 304, and the lower apex of the locking block 306 abuts against the circular insert 303. The height of the locking block 306 is aligned with the height of the circular insert 303, thus securing the retaining ring 304 and completing the installation. The upper plate 2 is quickly fixed on the mounting plate 1. When the upper plate 2 is quickly fixed on the mounting plate 1, the positioning pin 6 enters the circular positioning hole to prevent the upper plate 2 from rotating relative to the mounting plate 1, while ensuring the accuracy of the compressor valve plate installation. When it is necessary to disassemble the compressor valve plate, pull the pin 305 laterally to make the lower arm of the locking block 306 and the upper arm of the locking ring 304 misaligned, and then pull out the upper plate 2 directly to complete the quick disassembly of the compressor valve plate.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
