Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
Referring to shown in Fig. 1~2, a kind of safe light curtain of the utility model, comprising:
Transmitter 1 is made of several ballistic devices, emits infrared light；
Receiver 2 is made of several receiving devices, receives infrared light, the transmitter of the receiving device and transmitter
Part corresponds, and forms protection light curtain, generates light passing, shielding signals, while transmitting a signal to controller by signal cable
External equipment is controlled；
Signal cable, for the signal between transmission control unit (TCU) and transmitter, receiver；
Cable is controlled, for connecting controller and lathe, equipment, to realize the security control of lathe or other equipment；
Mounting bracket 3, for transmitter 1 and receiver 2 to be movably connected in board；
The mounting bracket 3 includes fixing seat 4, and the fixing seat 4 is cuboid, and upper surface is formed with track runner 5,
