Description

Technical Field

[0001] This utility model relates to the field of air compressor housing technology, specifically a galvanized sheet for assembling air compressor housings. Background Technology

[0002] The air compressor housing, also called the air compressor soundproof cover, serves to reduce noise.

[0003] Existing air compressor housings are assembled from multiple individual tin-plated sheets. These sheets are then welded together. However, the weld seams are prone to cracks and pores, allowing sound to leak out through these gaps and pores, making noise-reducing housings susceptible to sound leakage. Furthermore, to minimize sound leakage, existing air compressor housings typically minimize openings in the housing walls, creating a relatively enclosed space between the compressor and the housing, which is detrimental to heat dissipation. Utility Model Content

[0028] This utility model embodiment provides a galvanized sheet for assembling an air compressor housing, such as... Figure 1-7 As shown, it includes four galvanized plates 1, four metal sleeves 2, galvanized plate 3, and galvanized plate 4. The four galvanized plates 1 are connected end to end to form a rectangular frame. The metal sleeves 2 are fixedly inserted into the corners of the rectangular frame. The galvanized plate 2 is fixedly installed at the bottom of the rectangular frame, and the galvanized plate 4 is fixedly installed at the top of the rectangular frame.

[0029] It also includes multiple fixing blocks 5, each corresponding to one of the corners of the rectangular frame. The bottom of the fixing block 5 is connected to a post 51, and the fixing block 5 and the post 61 are integrally formed. The post 51 penetrates the galvanized plate 3 4 and is inserted into the metal sleeve 2. The post 51 has a pressure relief channel 511, the lower end of which extends to the bottom of the post 51, and the upper end of which extends to the top of the fixing block 5.

[0030] The top of the fixed block 5 is provided with a top block 6, and an extension is welded to the bottom of the top block 6, extending into the pressure relief channel 511. A sliding cavity 53 is provided inside the fixed block 5, and a piston rod 61 is welded to the top block 6. The lower end of the piston rod 61 slides in conjunction with the sliding cavity 53.

[0031] Working principle: When the heat inside the air compressor casing reaches a certain level, the internal pressure increases. The air pressure then pushes up the top block 6, thereby releasing pressure. During the pressure release process, the internal heat comes into contact with the outside environment, thus releasing heat.

[0032] Secondly, conventional existing technologies typically install a cooling fan inside the air compressor casing. The airflow from the cooling fan also pushes the top block 6 upward, dissipating heat and achieving the purpose of heat dissipation.

[0033] The galvanized plate has a through hole 41 that matches the insert post 51.

[0034] The two galvanized plates 1 are in contact with each other and serve as the corners of the rectangular frame. The top two sides of the galvanized plates 1 are provided with slots 11 that are compatible with the metal sleeves 2. The metal sleeves 2 are provided with pressure relief holes 21 facing the rectangular frame. The inner wall of the metal sleeves 2 and the inner wall of the galvanized plates 1 surround each other to form a mounting groove 22. The insert 51 is inserted into the mounting groove 22.

[0035] The inner wall of the metal sleeve 2 and the outer wall of the galvanized plate 1 form a mounting groove 23. A protrusion 52 is welded to the bottom of the fixing block 5. The protrusion 52 is inserted into the mounting groove 23. An insert plate 31 is welded to the top of the galvanized plate 23, and the insert plate 31 can be inserted into the mounting groove 23.

[0036] A spring 62 is fitted onto the piston rod 61. The lower end of the spring 62 is welded to the lower end of the piston rod 61, and the upper end of the spring 62 abuts against the top of the inner wall of the sliding cavity 53. The spring 62 causes the top block 6 to rise and then be subjected to a downward force, thus achieving a resetting effect.

[0037] A flange 32 is welded to the top edge of the galvanized plate 2 3. When the galvanized plate 2 3 abuts against the rectangular frame, the flange 32 covers the gap between the galvanized plate 2 3 and the rectangular frame.

[0038] A flange 2 42 is welded to the top edge of the galvanized plate 3 4. When the galvanized plate 3 4 abuts against the rectangular frame, the flange 2 42 covers the gap between the galvanized plate 3 4 and the galvanized plate 1.

[0039] In summary, the galvanized sheet used for assembling the air compressor housing comprises galvanized plate 1, galvanized plate 3, galvanized plate 4, and metal sleeve 2. The insertion method facilitates easier and faster installation of the air compressor housing. The metal sleeve 2 and the fixing block 5 work together to splice the various galvanized plates together. The metal sleeve 2 covers the gaps where the galvanized plates 1 contact each other, replacing traditional welding methods and preventing cracks and porosity on the weld surface that could cause sound leakage.

[0040] Furthermore, a through pressure relief channel 511 is provided inside the fixed block 5, and a top block 6 is provided on the top of the fixed block 5. Through the cooperation of the piston rod, spring 62, and sliding cavity 53, after the temperature inside the air compressor housing rises, the top block 6 rises, allowing the internal space of the air compressor housing to connect with the outside, thereby achieving the purpose of pressure relief and heat dissipation.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
