DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides an enamel sight glass with anti-corrosion performance, such as Figure 1 , Figure 2 and Figure 4 As shown, the enamel mirror includes a mirror body 1, a mounting plate 2 fixedly mounted on the mirror body 1, a lens 4 movably mounted inside the mounting plate 2, a mounting cover 6 rotatably mounted on one side of the mounting plate 2, a column 16 fixedly mounted on the mirror body 1, a threaded cylinder 17 rotatably mounted on the column 16, a movable plate 15 slidably mounted on the column 16, and a connecting rod 14 rotatably mounted on the movable plate 15.

[0023] An adjusting block 18 is fixedly connected to the top of the threaded barrel 17 , and the column 16 passes through the threaded barrel 17 and the adjusting block 18 in sequence. A limiting ring 19 that fits the top of the adjusting block 18 is fixedly connected to the column 16 , and a thread that matches the threaded barrel 17 is opened inside the movable plate 15 .

[0024] The lens 4 is an enamel sight glass, and a layer of enamel is burned on the internal flow-through parts of the sight glass body 1 to make it have corrosion resistance. The lens 4 is installed in the mounting plate 2, and the airtightness of the enamel sight glass is ensured by the closure of the mounting cover 6. The opening and closing of the mounting cover 6 are realized by the movable plate 15. The lifting and lowering of the movable plate 15 can indirectly affect the mounting cover 6. The movable plate 15 is movably sleeved on the column 16. When the movable plate 15 is lifted to a certain height, it will contact the threaded barrel 17. At this time, the threads inside the movable plate 15 will mesh with the threaded barrel 17. The adjusting block 18 can be rotated with the help of a wrench or other equipment to further lift the movable plate 15, thereby ensuring that the mounting cover 6 is close to the mounting plate 2. The threaded barrel 17 is sleeved on the upper half of the column 16. This design is to simplify the lifting and lowering time of the movable plate 15 and avoid spending a long time on adjusting the movable plate 15.

[0025] Furthermore, in order to improve the stability of the installation cover 6 during operation, as Figure 1 , Figure 2 and Figure 4 As shown, the second connecting block 8 is fixedly connected to the mounting cover 6, the third connecting block 9 is fixedly connected to the mounting plate 2, and the second connecting block 8 is rotatably connected to the inside of the third connecting block 9 through a plug-in rod.

[0026] The mounting cover 6 is connected to the mounting plate 2 via the second connecting block 8, so that the two are integrated into a whole with good stability.

[0027] Furthermore, in order to enable the installation cover 6 to be opened and closed, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the first connecting block 7 is fixedly connected to the mounting cover 6, and the interior of the first connecting block 7 is rotatably connected to an end of the connecting rod 14 away from the moving plate 15 through a plug-in rod.

[0028] By setting the connecting rod 14, the movable plate 15 can pull the installation cover 6 through the movable plate 15 when moving, so as to open or close it. The overall shape of the connecting rod 14 is arc-shaped, which can effectively avoid affecting the installation of the lens 4.

[0029] In order to increase the service life of the lens 4, Figure 1 , Figure 4 and Figure 5 As shown, a first gasket 3 that fits one side of the lens 4 is movably connected inside the mounting plate 2 , and a second gasket 5 that fits the other side of the lens 4 is movably connected inside the mounting cover 6 .

[0030] The lens 4 is clamped by the mounting plate 2 and the mounting cover 6. The first gasket 3 and the second gasket 5 are respectively installed on the side of the mounting plate 2 and the mounting cover 6 close to the lens 4. The two gaskets play a good protective role during the installation and use of the lens 4, avoiding direct contact between the lens 4 and the mounting plate 2 and the mounting cover 6 to cause wear.

[0031] It should be noted that, in order to facilitate the replacement of the gasket and the lens 4, Figure 4 , Figure 5 and Figure 6 As shown, a push piece 10 is movably connected inside the side of the mounting disk 2 that fits the first gasket 3, and a push rod 11 is fixedly connected to the side of the push piece 10 opposite to the first gasket 3. The push rod 11 passes through the mounting disk 2, and a limiting plate 13 is fixedly connected to the side surface of the push rod 11. A spring 12 is sleeved on the side surface of the push rod 11, one end of the spring 12 is fixedly connected to the mounting disk 2, and the other end of the spring 12 is fixedly connected to one side of the limiting plate 13.

[0032] After the installation cover 6 is opened, the push rod 11 can be pressed to drive the push piece 10 to push the first gasket 3 and the lens 4 out of the installation plate 2 for easy replacement. After the push rod 11 is released, the push rod 11 and the push piece 10 can be reset under the force of the spring 12 to avoid affecting the installation of the lens 4.

[0033] Furthermore, in order to facilitate the connection of the enamel sight glass to the pipeline, such as Figure 1 and Figure 2As shown, the mirror body 1 is fixedly connected to a connection plate 20 for connecting a pipeline, and the connection plate 20 is provided with a plurality of evenly distributed fixing grooves.

[0034] Two connection plates 20 for connecting other pipelines are fixedly mounted on the enamel sight glass. The holes provided on the connection plates 20 are used for inserting fixing parts such as bolts to fix with other pipelines.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
