Description

Technical Field

[0001] This utility model relates to the technical field of vacuum coating machine accessories, specifically an air outlet device with a built-in quick-release structure. Background Technology

[0002] Vacuum coating machines operate in a high-vacuum environment, utilizing physical vapor deposition (PVD) technology to convert film materials into a gaseous state through thermal evaporation and sputtering. This gas is then deposited onto the substrate surface to form thin films with specific properties and functions. The gas extraction device is a crucial auxiliary component of vacuum coating technology, primarily addressing the issue of gas removal from the vacuum chamber during the coating process. Through various vacuum pumps and associated valves and piping systems, the gas extraction device extracts and releases gases generated within the coating chamber due to material evaporation and desorption from the vessel walls into the atmosphere. This ensures the coating process can proceed under a stable high-vacuum environment, thereby guaranteeing the quality and performance of the thin film.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most air outlet devices lack a quick-release structure. When connecting to the air outlet pipe of a vacuum coating machine, a flange connection is usually used, and bolts and nuts are used for installation and fixing. The entire operation process is cumbersome and requires the use of various tools, which increases labor costs and wastes time, thus reducing work efficiency. Utility Model Content

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an air outlet device with a built-in quick-release structure, including a connecting component 1, a quick-release component 2 mounted on the four axes of the connecting component 1, an air outlet device body 3 mounted on the top of the connecting component 1, an air outlet pipe 4 mounted on the top of the air outlet device body 3, and a guide strip 5 mounted on the inner wall of the air outlet pipe 4.

[0024] The connecting assembly 1 includes a main connecting pipe 101, a first fixing collar 102 is installed on the upper outer side of the main connecting pipe 101, a secondary connecting pipe 103 is installed on the top of the main connecting pipe 101, a second fixing collar 104 is installed on the lower outer side of the secondary connecting pipe 103, a limit ring 105 is installed at the bottom of the second fixing collar 104, a sliding collar 106 is installed on the outer side of the secondary connecting pipe 103 at the top of the second fixing collar 104, and a first limit block 107 is installed around the inner side of the sliding collar 106.

[0025] The quick-release assembly 2 includes a connecting frame 201 installed around the top of the sliding collar 106. A connecting block 203 is installed on the inner side of the connecting frame 201 via a connecting shaft 202. A push block 204 is installed on one side of the top of the connecting block 203. A connecting rod 205 is installed at the bottom of the push block 204. A second limiting block 206 is installed at the bottom of the connecting rod 205. A spring 207 is installed in the middle of one side of the connecting rod 205.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the main connecting pipe 101 is installed at the air outlet of the vacuum coating machine.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the first fixing collar 102 is provided with a first groove that matches the external dimensions of the limiting ring 105, and a sealing gasket is installed on the inner side of the first groove.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a second groove with the same external dimensions and structure as the first limiting block 107 is provided on the lower part of the outer periphery of the secondary connecting pipe 103.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, a slot with the same external dimensions and structure as the connecting rod 205 is provided on one side of the top of the connecting block 203.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one side of the spring 207 is fixedly installed around the outside of the sliding collar 106, and the connecting rod 205 and the spring 207 form an elastic structure.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the guide bar 5 is designed in a spiral shape.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the air venting device with a built-in quick-release structure operates as follows during use:

[0033] First, when installation is required, slide the sliding collar 106 upwards. At this time, the first limiting block 107 will slide within the second groove. Then, install the secondary connecting pipe 103. At this time, the bottom of the secondary connecting pipe 103 will be attached to the top of the main connecting pipe 101, and the bottom of the second fixing collar 104 will slowly be attached to the top of the first fixing collar 102. The limiting ring 105 will be inserted into the inner side of the first groove and squeeze the sealing gasket inside the first groove to ensure the sealing after installation. At this time, the connecting rod 205 can be pulled to cause the spring 207 to undergo elastic deformation. Then, slide the sliding collar 106 downwards. When the bottom of the sliding collar 106 is attached to the top of the second fixing collar 104, release the connecting rod 205. At this time, the spring 207 will undergo elastic deformation. The connecting rod 205 slides inside the slot, causing the second limiting block 206 to move horizontally. This allows the top of the second limiting block 206 to slowly adhere to the bottom of the first fixing collar 102, thus limiting its position and completing the overall installation. The air outlet device 3 can then be activated, allowing air to be discharged through the air outlet pipe 4. During air discharge, the spiral-designed guide strip 5 ensures a spiral flow of gas, resulting in better air discharge. When disassembly is required, pulling the connecting rod 205 causes the spring 207 to elastically deform, causing the top of the second limiting block 206 to slowly detach from the bottom of the first fixing collar 102. Once completely detached, the auxiliary connecting pipe 103 can be disassembled, achieving a quick disassembly.
