[0002] Safety gratings are photoelectric safety protection devices (also known as safety protectors, punch protectors, infrared safety protection devices, etc.). Generally speaking, safety gratings exist in pairs, divided into transmitting ends and receiving ends. Safety gratings are photoelectric devices that prevent people from approaching mobile machinery, which can avoid casualties. Such mobile machinery includes punching machines, winders, palletizers, elevators, etc. Safety gratings can be used to replace traditional mechanical barriers or other forms of mechanical protection, and can also increase the maintainability of equipment.

[0003] Among them, the "safety grating that is easy to install" disclosed in the application number "CN201920397662.5" is also an increasingly mature technology, including a transmitting grating and a receiving grating; the transmitting grating includes a transmitting shell, a light-transmitting cover, a laser positioning assembly and a first level bubble, and the receiving grating includes a receiving light shield corresponding to the light-transmitting cover and positioning bull's eyes respectively distributed on the outside of the two ends of the receiving light shield and corresponding to the laser positioning assembly. After the transmitting grating is fixedly installed, the device emits a beam of visible light through two groups of laser positioning assemblies, so that when installing the receiving grating, the fixed position of the receiving grating can be adjusted very conveniently according to the beam emitted by the laser positioning assembly. During installation, it is only necessary to ensure that the two positioning bull's eyes on the receiving grating are respectively facing the beams emitted by the two groups of laser positioning assemblies to ensure that the transmitting grating and the receiving grating are in an aligned position. The device has a simple structure, and can easily align the transmitting grating and the receiving grating during the installation process, and has strong practical value and market promotion value. After further retrieval, the "a kind of safety grating easy to assemble" disclosed in the application number "CN202223009795.1" includes a mounting plate, and an assembling mechanism is arranged on the upper end of the mounting plate.

The circumferential surfaces of the first threaded rod and the second threaded rod are threadedly connected with a clamping plate. Through the provided assembly mechanism and clamping mechanism, the vertical rod can be quickly disassembled or assembled. The structure is simple, the operation is convenient, time-saving and labor-saving, and the overall work efficiency is improved. In addition, the assembly setting can replace any component when the component is damaged without replacing the entire component, thereby reducing the subsequent use cost, being more practical, and being more flexible to use.
