Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In order to solve the problem that in the actual installation process of the existing explosion-proof infrared temperature measurement window, one of the explosion-proof covers at both ends of the light-transmitting crystal cannot be independently disassembled, and it is more difficult to disassemble one of the explosion-proof covers. It is necessary to completely disassemble the explosion-proof infrared temperature measurement window and adjust the internal transmission structure, which affects the installation and use efficiency of the infrared temperature measurement window. The following technical solutions are provided in this embodiment:

[0022] An infrared temperature measurement window facilitating direct disassembly of the panel, including a base 1. A light-transmitting crystal 12 is arranged in the middle of the interior of the base 1. As Figure 1 and Figure 2 shown, a connecting shaft 13 penetrates through one side of the base 1 and extends through and to the front and rear ends of the base 1. Protruding pieces 7 are welded at both ends of the connecting shaft 13. Explosion-proof covers 2 are arranged at the front and rear ends of the light-transmitting crystal 12. A first concave cavity 5 is arranged on one side inside the explosion-proof cover 2, and the center position of the first concave cavity 5 overlaps with that of the protruding piece 7. During rotation, the explosion-proof cover 2 can rotate around the protruding piece 7, and rotate and unfold to expose the light-transmitting crystal 12;

[0023] In this embodiment, an installation ring 10 for installation is arranged inside the protruding piece 7, and the installation ring 10 is fixedly welded to the protruding piece 7. As Figure 3 and Figure 4 shown, a concave installation cavity 11 is arranged inside the installation ring 10. A bolt 3 is arranged on one side outside the installation cavity 11, and the outside of the bolt 3 is in threaded fit with the inside of the installation cavity 11. The bolt 3 passes through the first concave cavity 5 in sequence and is embedded inside the installation cavity 11 to complete the fixation of the explosion-proof cover 2;

[0024] In this embodiment, an annular installation cavity 8 is disposed around the outside of the installation ring 10, as shown in Figure 3 , Figure 4 and Figure 5 . Four strip-shaped installation cavities 9 are evenly distributed around the outside of the annular installation cavity 8. A fixing ring 4 for embedding is disposed inside the annular installation cavity 8, and the fixing ring 4 is fixedly welded to the explosion-proof cover 2. During the actual installation of the explosion-proof cover 2, while the explosion-proof cover 2 is fixed through the bolts 3, the explosion-proof cover 2 will be embedded into the annular installation cavity 8 through the anti-slip strips 6. Four anti-slip strips 6 are evenly distributed around the outside of the fixing ring 4, and the anti-slip strips 6 are fixedly welded to the fixing ring 4. When the fixing ring 4 slides into the annular installation cavity 8, the fixing ring 4 will drive the anti-slip strips 6 to be respectively embedded into the strip-shaped installation cavities 9. The protruding anti-slip strips 6 can prevent the explosion-proof cover 2 from slipping after being fixed by the bolts 3.

[0025] In this embodiment, a second recessed cavity 14 for recessing and connecting is disposed on the surface of the explosion-proof cover 2 facing the protruding piece 7, as shown in Figure 2 , Figure 3 and Figure 5 . The second recessed cavity 14 is recessed inside the explosion-proof cover 2. A rubber ring 15 is disposed on one side inside the second recessed cavity 14, and the rubber ring 15 is disposed around the inside of the second recessed cavity 14. The rubber ring 15 is fixedly bonded to the explosion-proof cover 2 by glue. When the bolt 3 rotates and fixes the explosion-proof cover 2, the protruding piece 7 will be embedded into the second recessed cavity 14 and contact the rubber ring 15, and the rubber ring 15 fills the gap between the connecting positions.

[0026] Working principle: When using the device and installing the light-transmitting crystal 12 for protection, the fixing ring 4 connected to the explosion-proof cover 2 slides into the annular installation cavity 8. At the same time of insertion, the fixing ring 4 will drive the four anti-slip strips 6 disposed around it to be embedded into the strip-shaped installation cavities 9 together. The bolt 3 is passed through the first recessed cavity 5 and rotated and inserted into the installation cavity 11. As the bolt 3 continues to rotate, the protruding piece 7 is continuously embedded into the second recessed cavity 14, continuously embedded into the second recessed cavity 14 and contacts the rubber ring 15. The threaded fit between the bolt 3 and the inner wall of the installation cavity 11 and the extrusion of the bolt 3 on the explosion-proof cover 2 are used to fix the explosion-proof cover 2. When disassembling the explosion-proof cover 2, rotate the bolt 3 so that the bolt 3 is taken out from the installation cavity 11 and the first recessed cavity 5 in sequence. After taking out, the explosion-proof cover 2 can be slid out.
