[0029] The light strip 9 is fixedly mounted on the inner wall of the protective ring 6, and the terminal head 10 is fixedly mounted on the middle part of the outer surface of the front end of the protective ring 6. The output end of the terminal head 10 is electrically connected to the input end of the light strip 9; the connecting shaft 8 is rotatably connected between one side of the protective cover 7 and the side of the upper end outer surface of the protective ring 6 away from the clamping component 11; the first limit block 12 is fixedly mounted on the outer surface of the end of the protective cover 7 away from the connecting shaft 8, and the clamping hole 13 is opened on the upper end outer surface of the first limit block 12; the fixed block 18 is fixedly mounted on the upper part of the outer surface of the side of the protective ring 6 away from the connecting shaft 8, the installation cavity 19 is opened inside one end of the fixed block 18, and the through hole 16 is opened at one end of the upper end outer surface of the fixed block 18. The lower end of the through hole 16 is connected to the upper end of the mounting cavity 19, and the second limit block 15 and the compression spring 14 are both located in the mounting cavity 19. The lower end outer surface of the compression spring 14 is fixedly connected to the bottom of the mounting cavity 19, and the upper end outer surface of the compression spring 14 is fixedly connected to the lower end outer surface of the second limit block 15.

The lower end outer surface of the second limit block 15 is elastically connected to the bottom of the mounting cavity 19 through the compression spring 14, and the upper part of the snap-in pin 17 and the snap-in hole 13 are snap-fitted.

[0030] It should be noted that the present invention is a safety split sight glass. The sight glass body 1 and the connecting tube 4 described in the text belong to the prior art, which can be effectively known to the technicians in the relevant technical field, and the details will not be repeated here. The upper connecting ring 2 is installed on the outer surface of the upper end of the sight glass body 1, and a protective component 3 is provided. When the protective component 3 and the sight glass body 1 are assembled, the external threaded connecting ring 20 at the bottom of the protective ring 6 is threadedly connected to the inner wall of the upper connecting ring 2 to realize the assembly of the protective component 3, so that the protective component 3 is easy to assemble and disassemble.

When the locking pin 17 is separated from the locking hole 13, the protective cover 7 can be rotated to open, which is convenient for operation; when closing the protective cover 7, the locking pin 17 is squeezed, so that the upper end of the locking pin 17 enters the through hole 16, and the protective cover 7 is rotated closed. When the locking hole 13 in the first limit block 12 reaches the upper part of the locking pin 17, the reaction force of the compression spring 14 drives the upper end of the locking pin 17 to be locked in the first limit block 12, thereby limiting the protective cover 7 and facilitating operation.
