Description

Technical Field

[0001] The present application relates to the technical field of air pressure monitoring devices, and in particular to an air pressure monitoring device for backfilling gas in a vacuum degassing station. Background Art

[0002] A vacuum degasser is a device specially used to remove gas from objects. It uses vacuum technology to extract the gas around the object, thereby forming a vacuum environment inside the object. Vacuum degassers are widely used in various fields, such as chemical industry, food, medicine, etc., and play an important role.

[0003] During the vacuum degassing and backfilling processes, air pressure monitoring equipment is required to observe in real time whether the air pressure inside the equipment is stable. The existing technology has a relatively mature air pressure monitoring alarm box. In order to improve and maintain the high sensitivity of the air pressure monitoring alarm box and reduce its error, the staff needs to inspect it regularly. During the inspection, the staff needs to open the alarm box shell and test its internal circuit components and instruments. However, the traditional alarm box shell is fixed with screws, which will be worn after multiple inspections and twisting, resulting in insufficient screwing force between the screws and the screw holes, causing the shell to loosen, making its installation unstable.

[0020] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0021] The present application embodiment discloses a gas pressure monitoring device for backfilling gas in a vacuum degassing station. Figure 1-Figure 4A pressure monitoring device for backfilling gas in a vacuum degassing station comprises a pressure monitoring alarm box 1, a pair of No. 1 plug-in holes 6 are provided on both sides of the pressure monitoring alarm box 1, and a plurality of mounting plates 3 are fixed on the pressure monitoring alarm box 1; a sealing cover 2 is connected to the pressure monitoring alarm box 1, an embedding frame 5 is fixed on the sealing cover 2, the embedding frame 5 is embedded in the pressure monitoring alarm box 1, and a No. 2 plug-in hole 14 is provided on the embedding frame 5; and a locking mechanism is also included, which is installed on the pressure monitoring alarm box 1 and is used to connect and fix the pressure monitoring alarm box 1 and the sealing cover 2. When the pressure monitoring alarm box 1 and the sealing cover 2 are mutually socketed, the No. 2 plug-in hole 14 corresponds horizontally to the No. 1 plug-in hole 6, and the No. 2 plug-in hole 14 has the same size as the No. 1 plug-in hole 6.

[0022] In this embodiment, if Figure 3 and Figure 4 As shown, a plurality of sliding columns 7 are fixed on the air pressure monitoring alarm box 1, and a fixing plate 11 is fixed on the sliding column 7. The locking mechanism includes a rotating plate 8 sleeved on the sliding column 7, and an insertion rod 9 is fixed at one end of the rotating plate 8 away from the sliding column 7. The insertion rod 9 is adapted to the No. 1 insertion hole 6 and the No. 2 insertion hole 14. A spring 12 is sleeved on the sliding column 7, and the spring 12 is respectively connected to the rotating plate 8 and the fixing plate 11. The rotating plate 8 can be displaced by the elastic force of the spring 12. A pull ring 10 is fixed on the rotating plate 8. When installing, the sealing cover 2 is installed on the air pressure monitoring alarm box 1, and then the pull ring 10 is pulled respectively. At this time, the spring 12 is compressed, and the rotating plate 8 is rotated to the insertion rod 9 corresponding to the No. 1 insertion hole 6 through the pull ring 10. The pull ring 10 is slowly released. The rotating plate 8 moves due to the elastic reset force of the spring 12, which will cause the insertion rod 9 to be inserted into the No. 1 insertion hole 6. Because the No. 1 insertion hole 6 and the No. 2 insertion hole 14 correspond horizontally and are adjacent, the insertion rod 9 will be inserted into the No. 2 insertion hole 14 at this time, so that the sealing cover 2 is limited and fixed. When disassembling, just reverse the above installation operation.

[0023] In this embodiment, if Figure 3 As shown, the end of the insertion rod 9 is provided with a chamfer 13, and the chamfer 13 facilitates the insertion of the insertion rod 9 into the No. 1 insertion hole 6 more smoothly, facilitates the installation operation, and avoids jamming.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, the sealing cover 2 is provided with a plurality of circular holes 4, and the circular holes 4 are used to expose the instrument panel installed inside the air pressure monitoring alarm box 1, so as to facilitate observation by the staff.

[0025] The implementation principle of the air pressure monitoring device for backfilling gas in a vacuum degassing station according to the embodiment of the present application is as follows: during installation, the sealing cover 2 is installed and sleeved on the air pressure monitoring alarm box 1, and then the pull rings 10 are pulled respectively. At this time, the spring 12 is compressed, and the rotating plate 8 is rotated through the pull ring 10 until the insertion rod 9 corresponds to the No. 1 insertion hole 6, and the pull ring 10 is slowly released. The rotating plate 8 moves due to the elastic reset force of the spring 12, which causes the insertion rod 9 to be inserted into the No. 1 insertion hole 6. Since the No. 1 insertion hole 6 and the No. 2 insertion hole 14 correspond horizontally and are adjacent, the insertion rod 9 will be inserted into the No. 2 insertion hole 14 at this time, so that the sealing cover 2 is limited and fixed. When disassembling, only the above-mentioned installation operation needs to be reversed. That is, by setting the sealing cover 2, the round hole 4, the embedded frame 5, the No. 1 plug-in hole 6, the sliding column 7, the rotating plate 8, the plug-in rod 9, the pull ring 10, the fixing plate 11, the spring 12, the chamfer 13 and the No. 2 plug-in hole 14, by sleeve-connecting the sealing cover 2 on the air pressure monitoring alarm box 1, and pulling the rotating plate 8 respectively to insert the plug-in rod 9 into the No. 1 plug-in hole 6 and the No. 2 plug-in hole 14, the sealing installation of the air pressure monitoring alarm box 1 can be completed. For disassembly, only the rotating plate 8 needs to be pulled to make the plug-in rod 9 away from the No. 1 plug-in hole 6 and the No. 2 plug-in hole 14. The operation is relatively simple, and the staff does not need to use a screwdriver to disassemble, which is convenient for long-term and multiple inspections and maintenance of the air pressure monitoring alarm box.
