[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4An embodiment of this utility model provides a safety light curtain device, including a mounting base 2, a transmitter 7, a receiver 9, and a controller 14. The mounting base 2 is provided in two sets. A mounting plate 1 is fixedly connected to the side of the mounting base 2. An adjusting block 3 is movably connected inside the mounting base 2. A telescopic rod 4 is fixedly connected to the side of the adjusting block 3. A positioning bolt 11 is provided at the front end of the telescopic rod 4. A mounting bracket 5 is fixedly connected to the side of the telescopic rod 4. Two sets of mounting sleeves 6 are installed on the mounting bracket 5. A clamp 8 is fixedly connected to the mounting sleeve 6. The transmitter 7 and the receiver 9 are respectively embedded inside the clamp 8. A connecting shaft 12 is fixedly connected to the top of the adjusting block 3. A limit rod 16 is movably hinged to the outside of the connecting shaft 12. An adjusting plate 13 is fixedly connected to the top of the mounting base 2. A limit groove 15 is provided inside the adjusting plate 13.

[0025] Both transmitter 7 and receiver 9 are provided with connecting wires at their bottom ends. Transmitter 7 and receiver 9 are connected to controller 14 through the connecting wires. The telescopic cylinder inside telescopic rod 4 is provided with a locking groove. Positioning bolt 11 can be embedded in the locking groove. Transmitter 7 and receiver 9 are installed on the same horizontal line. Mounting bolts are provided on mounting plate 1.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, when installing the equipment, first use the mounting plate 1 on the mounting base 2 to fix it, and then adjust it according to the width range of the protection. After the telescopic rod 4 moves and adjusts the mounting bracket 5, it can be fixed with the positioning bolt 11. Subsequently, the light curtain formed by the transmitter 7 and the receiver 9 has a protective effect. Once the light curtain is blocked, the controller 14 can control the equipment to stop urgently. After installation, the width of the light curtain protection can also be adjusted according to the needs.

[0027] The top end of the connecting shaft 12 moves through the mounting base 2 and the adjusting plate 13. The top end of the connecting shaft 12 is fixedly connected to a handle 17. The limiting groove 15 is provided with eight sets and is distributed in a ring inside the adjusting plate 13. The limiting rod 16 is embedded inside the limiting groove 15.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the angle of the light curtain protection can be adjusted according to the protection requirements. When adjusting, first move the limiting rod 16 out of the limiting groove 15, then the connecting shaft 12 can drive the mounting bracket 5 to adjust to the appropriate protection angle. Then, insert the limiting rod 16 into the limiting groove 15 to limit and fix it. The mounting sleeve 6 on the clamp 8 can be rotated and fixed on the mounting bracket 5 to accurately adjust the position of the transmitter 7 and the receiver 9.

[0029] The clamp 8 has a clamping bolt 10 at its front end and a clamping plate 18 movably connected to the rear end of the clamping bolt 10. The clamping plate 18 is located inside the clamp 8. The mounting sleeve 6 has a locking bolt. The mounting sleeve 6 is fitted onto the outside of the mounting bracket 5 and is fixed by the locking bolt.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the transmitter 7 and receiver 9 can be quickly removed from the installed equipment row. During disassembly, rotate the clamping bolt 10, and then the transmitter 7 and receiver 9 can be directly removed from inside the clamp 8. The position of the clamping plate 18 can be adjusted according to the size of the transmitter 7 and receiver 9 to achieve flexible and stable clamping.

[0031] Working principle: During installation, the device is first fixed using the mounting plate 1 on the mounting base 2. Then, it is adjusted according to the required width of protection. The telescopic rod 4 moves the mounting bracket 5 for adjustment and is then fixed using the positioning bolts 11. Subsequently, the light curtain formed by the transmitter 7 and receiver 9 provides protection. Once the light curtain is blocked, the controller 14 can control the device to stop immediately. After installation, the width of the light curtain protection can be adjusted as needed, and the angle of the light curtain protection can also be adjusted according to the protection requirements. During adjustment, the limit rod 16 is first moved out of the limit groove 15, and then the connecting shaft 12 can drive the mounting bracket 5 to adjust to the appropriate protection position. After adjusting the angle, the limiting rod 16 is inserted into the limiting groove 15 for positioning and fixation. The mounting sleeve 6 on the clamp 8 can be rotated and fixed on the mounting bracket 5 to precisely adjust the position of the transmitter 7 and receiver 9. The transmitter 7 and receiver 9 can be quickly removed from the installed equipment. During disassembly, rotate the clamping bolt 10, and then remove the transmitter 7 and receiver 9 directly from the clamp 8. The position of the clamping plate 18 can be adjusted according to the size of the transmitter 7 and receiver 9 to achieve flexible and stable clamping. This structure facilitates quick disassembly and improves the ease of inspection and maintenance.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
