The mounting block 6 and the device body 1 are fixed by a disassembly assembly. The disassembly assembly is released to separate the mounting block 6 and the device body 1. The electric push rod 13 fixes the limit block 17 by pressing the push plate 14, thereby fixing the photoelectric sensor 16. The electric push rod 13 releases the push plate 14 to remove the limit block 17 and the photoelectric sensor 16. The device can be installed and disassembled through the above structure.

As shown in Figure 3, the disassembly assembly includes a fixed block 7, a spring 8, a block clamp 9 and a card plate 10. The fixed block 7 is connected to the mounting block 6. The spring 8 is arranged inside the fixed block 7. Different inner wall sides of one end of the block clamp 9 are respectively connected to the two ends of the spring 8. The other end of the block clamp 9 is clamped and connected to the card plate 10, and the card plate 10 is installed on the device body 1.

The disassembly component is used to connect the mounting block 6 and the device body 1. The mounting block 6 and the device body 1 are connected by the card block clip 9 on the mounting block 6 and the card plate 10 on the device body 1. During disassembly, the mounting block 6 is lifted to one side so that the clamp body on the same side of the card block clip 9 is separated from the card plate 10. Then, the mounting block 6 is lifted to the opposite side so that the clamp body on the opposite side of the card block clip 9 is also separated from the card plate 10, thereby separating the mounting block 6 and the device body 1.

As shown in FIG. 4 , which is a cross-sectional view of the mounting block of the present invention, a clamping groove 15 is provided on the inner wall of the mounting block 6 .

The limiting block 17 passes through the slot 15 , and the shape of the limiting block 17 matches the structure of the slot 15 . When the limiting block 17 rotates to overlap with the slot 15 , the limiting block 17 can be taken out from the slot 15 .

The mounting block 6 also includes a conductive component, which includes a first corrugated electric tube 4, a first socket 5, a second corrugated electric tube 11, a plug 12 and a second socket 18. The second corrugated electric tube 11 is fixedly connected with the plug 12 at both ends.

The outer wall of the plug 12 at the other end is provided with the second socket 18, and the second socket 18 is connected with the photoelectric sensor 16. The outer wall of the second corrugated electric tube 11 is fixedly connected to the inner wall of the mounting block 6 and the inner wall of the push plate 14. The device body 1 is embedded with a control panel 2, and the inner wall of the device body 1 is fixedly connected with a battery 3, and the battery 3 is fixedly connected with the first corrugated electric tube 4. The battery 3 is electrically connected to the control panel 2, and the control panel 2 is electrically connected to the electric push rod 13.

The conductive component is used to connect the battery 3 and the photoelectric sensor 16 when the mounting block 6 and the device body 1 are connected. By inserting the plug 12 into the first socket 5, the first corrugated tube 4 and the second corrugated tube 11 are turned on. At the same time, since the second corrugated tube 11 is connected to the second socket 18, and the second socket 18 is connected to the photoelectric sensor 16, the connection between the battery 3 and the photoelectric sensor 16 is realized. When the mounting block 6 and the device body 1 are separated, the plug 12 is separated from the first socket 5, and the connection between the battery 3 and the photoelectric sensor 16 is disconnected.

As shown in FIG. 5 , which is a structural diagram of the photoelectric sensor of the present invention, one end of the second socket 18 is embedded in the limiting block 17 .

The specific disassembly and assembly principle of the device body 1 of the utility model is as follows: when the device body 1 is inspected and repaired, the installation block 6 is first bent in the same direction, and then bent in the opposite direction, and the card block clip 9 is taken out from the card plate 10, and the installation block 6 can be removed from the device body 1, and the device body 1 can be inspected and repaired. When installing, first insert the plug 12 into the first socket 5, and the card block clip 9 on one side is inserted into the card plate 10, and then it is bent in the opposite direction to make the card block clip 9 on the other side inserted into the card plate 10, and the installation can be completed.

The specific disassembly and assembly principle of the photoelectric sensor 16 of the utility model is: when the photoelectric sensor 16 is damaged, the control panel 2 is used to control the electric push rod 13 to perform a contraction movement, and the electric push rod 13 drives the push plate 14 to move, so that the limit block 17 and the photoelectric sensor 16 can be removed from the mounting block 6, and the photoelectric sensor 16 can be replaced or repaired. During installation, the limit block 17 is inserted into the mounting block 6 in a horizontal direction, and when it is inserted to the corresponding position, it is rotated again to clamp the limit block 17 into the card slot 15, and then the electric push rod 13 drives the push plate 14 to limit the limit block 17 and the photoelectric sensor 16, and the installation can be completed.

The working principle of the mounting block 6 of the utility model is as follows: when the photoelectric sensor 16 is installed, the push plate 14 will also drive the second corrugated tube 11 to stretch, thereby driving the right plug 12 to be inserted into the second socket 18, and the battery 3 and the control panel 2 are energized with the photoelectric sensor 16, so that the control panel 2 is connected to the photoelectric sensor 16.
