Embodiment 1
[0024] see Figure 1~2 , in an embodiment of the present invention, a photoelectric sensor multi-functional protection device, including a mounting case 1 and a protective cover, a protective glass 4 is embedded on the side wall of the mounting case 1, and a protective glass 4 is embedded on the side wall of the mounting case 1. Sponge strips are attached to the contact positions of the protective glass 4, which can buffer and protect the protective glass 4. The protective cover is arranged on the outside of the installation shell 1, and a gap is provided between the inner wall of the protective cover and the outer wall of the installation shell 1 to protect the protective glass 4. The side of the cover close to the protective glass 4 has an opening. Furthermore, a protective mechanism for protecting the protective glass 4 is installed on the protective cover. The protective mechanism includes a protective plate 6 and a switch for driving the protective plate 6 to open and clos...
Embodiment 2
[0028] see image 3 The difference between the embodiment of the present invention and embodiment 1 is that the outer wall of the installation housing 1 is located at the ventilation net 5 and is provided with a placement screen frame 23, and a desiccant is placed in the placement screen frame 23 for reducing Moisture enters the installation housing 1 .
[0029] The working principle of the present invention is: when the photoelectric sensor is working, the protection plate 6 is opened; Ventilation nets 5 are installed on both side walls of the housing 1. After the photoelectric sensor is placed on the placement board, the placement board descends downward under the action of gravity, and the placement board presses down on the horizontal section of the L-shaped bar 2, and the L-shaped bar 2 Rotate through the guide rod 3 to drive the splint 19 to move towards the photoelectric sensor, thereby realizing automatic positioning and clamping of the photoelectric sensor. The opera...
