Technical Field

[0001] The present application relates to the field of machine room fans, and in particular to a machine room fan silencer that is easy to maintain. Background Art

[0002] With the rapid development of high-end industrial production, it has become very common to provide an integrated machine room for production workshops or other production occasions. In order to ensure the circulation of internal air and the outside world, the machine room is equipped with a fan. Since the fan makes a lot of noise when it is turned on, most fans are now equipped with a silencer, which can reduce the noise generated by the fan when it is running to a certain extent.

[0003] The fan and the silencer are basically fixed together by multiple bolts. Since the silencer needs to be inspected and maintained regularly, the two need to be disassembled at this time. It is inconvenient to disassemble and assemble multiple bolts. Therefore, a machine room fan silencer that is easy to inspect is needed. The fan and the silencer can be quickly installed by the cooperation of a hoop and a single bolt, thereby improving the convenience of disassembly and assembly of the silencer, and thus improving the convenience of later inspection and maintenance of the fan silencer.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Example 1:

[0035] Combine Figure 1-Figure 5 , the embodiment of the present application discloses a machine room fan silencer that is easy to maintain, including a silencer 1: a fan 2 is arranged on the outside of the silencer 1, and a ring block 3 is fixedly connected to the surface of the silencer 1 and the fan 2, and a hoop ring 1 4 and a hoop ring 2 5 are commonly provided on the outside of the two ring blocks 3, and the surfaces of the hoop ring 1 4 and the hoop ring 2 5 are respectively fixedly connected to a hole block 7 and a cylindrical box 6, a sliding rod 8 is provided through the front of the cylindrical box 6, and the rear end of the sliding rod 8 passes through the cylindrical box 6 and extends to the inner cavity of the hole block 7, and a circular plate 9 is fixedly connected to the surface of the sliding rod 8, and a spring 10 is fixedly connected between the circular plate 9 and the inner wall of the cylindrical box 6, and a rectangular block 13 and a rectangular block 2 14 are respectively fixedly connected to the surfaces of the hoop ring 1 4 and the cylindrical box 6, and the inner cavities of the rectangular block 13 and the rectangular block 2 14 are commonly installed with a bolt rod 15, and the surface of the bolt rod 15 is threadedly connected with a nut block 16.

[0036] Example 2:

[0037] Combine Figure 1-Figure 5 , the hoop ring 1 4 and the hoop ring 2 5 are rotatably connected by a rotating shaft, the inner walls of the hoop ring 1 4 and the hoop ring 2 5 are arc-shaped grooves, and the inner walls of the hoop ring 1 4 and the hoop ring 2 5 are adhered with a sealing strip 18, which is a rubber strip. Through the setting of the sealing strip 18, the contact between the hoop ring 1 4 and the hoop ring 2 5 and the ring block 3 is sealed, avoiding the occurrence of gaps between the hoop ring 1 4 and the hoop ring 2 5 and the ring block 3, thereby improving the sealing of the surface of the ring block 3. The sliding rod 8 is slidably connected to the cylindrical box 6, the inner diameter of the hole block 7 is larger than the outer diameter of the sliding rod 8, the surface of the hoop ring 4 is integrally formed with a card block 11, and the rear side of the cylindrical box 6 is integrally formed with a card strip 12. The clamping strip 12 is located in the inner cavity of the clamping block 11. Through the coordinated use of the clamping block 11 and the clamping strip 12, the connection between the hoop ring 1 4 and the hoop ring 2 5 is limited in the left and right directions, thereby avoiding the left and right shaking between the two. The surface of the rectangular block 13 is provided with an elliptical hole adapted to the bolt rod 15, and the surface of the rectangular block 2 14 is provided with a through hole adapted to the bolt rod 15. The surface of the bolt rod 15 is sleeved with a washer 17. The rectangular block 13 and the nut block 16 are both fitted with the washer 17. Through the setting of the washer 17, the friction on the surface of the nut block 16 is increased, thereby avoiding the loosening and falling off of the nut block 16 due to the vibration generated by the operation of the fan.

[0038] Working principle: When the utility model is used, the user moves the silencer 1 and the fan 2 close together, then holds the hoop 1 4 and the ring block 3 and rotates them to wrap the two ring blocks 3. During this process, the slide bar 8 is pulled in advance to drive the spring 10 to compress through the circular plate 9. Then, when the hoop 1 4 and the hoop 2 5 are close together on the surface of the ring block 3, the slide bar 8 is loosened. At this time, the rebound force of the spring 10 drives the slide bar 8 to move through the circular plate 9 and enter the inner cavity of the hole block 7. Through the coordinated use of the hole block 7, the slide bar 8, the circular plate 9 and the spring 10, the hoop 1 4 can be compressed. It is pre-fixed with the sleeve of hoop ring 2 5 on the surface of ring block 3, and then the rectangular block 13 and the rectangular block 2 14 are tightened and fixed by the cooperation of bolt rod 15 and nut block 16, and then hoop ring 1 4 and hoop ring 2 5 are locked. Similarly, hoop ring 1 4 and hoop ring 2 5 can be quickly removed from the surface of ring block 3, realizing the rapid installation of fan and muffler through the cooperation of hoop and single bolt, thereby improving the convenience of disassembly and assembly of muffler, and thereby improving the convenience of later maintenance of fan muffler.

[0039] To sum up: the machine room fan silencer that is easy to maintain can pre-fix the hoop ring 1 4 and the hoop ring 2 5 on the surface of the ring block 3 through the coordinated use of the hole block 7, the slide rod 8, the circular plate 9 and the spring 10, and then tighten and fix the rectangular block 13 and the rectangular block 2 14 through the coordination of the bolt rod 15 and the nut block 16, and then lock the hoop ring 1 4 and the hoop ring 2 5, so that the fan and the silencer can be quickly installed through the coordination of the hoop and the single bolt, thereby improving the convenience of disassembly and assembly of the silencer, and thereby improving the convenience of later maintenance of the fan silencer.

[0040] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
