[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0014] 1. The maintenance safety sign system sets up an electronic warning sign with built-in horizontal sensors, angle sensors, RFID electronic tags, etc. Once the electronic warning sign is set, the alarm itself will emit a buzzer alarm when any of the horizontal position and angle position of the sign changes. At the same time, the alarm information is transmitted to the signal receiving device through Bluetooth, or 4G / 5G network, or industrial wireless network. The signal receiving device transmits the information to the maintenance safety sign system through the network. The maintenance safety sign system notifies relevant personnel through broadcasting or SMS push. By setting up an anti-slip mechanism, the various structures of the anti-slip mechanism cooperate with each other, thereby ensuring the stable placement of the electronic warning sign, preventing unintentional touch by irrelevant personnel, and ensuring the safety of personnel and equipment.
[0015] 2. The inspection safety sign system positions the card plate by setting a limit plate. When placing the electronic warning sign, the card plate must first be inserted into the limit plate, and the cross plate is limited by setting a limit cylinder. By setting a limit spring, when the user pulls the two pull rods in opposite directions, the two card blocks will exit the anti-slip groove, and the card plate will be loosened, making it convenient to take out the electronic warning sign. When the card plate is placed stably, release the two pull rods, and the limit spring pushes the two card blocks into the anti-slip groove, which initially ensures the stability of the electronic warning sign. By setting an electric push rod, the controller drives the two sets of electric push rods to extend and retract, thereby driving the two card seats to move in opposite directions, further fixing the electronic warning sign, and ensuring the stability of the electronic warning sign.

When the electronic warning sign 3 is set, if any of the horizontal position and angular position of the sign body changes, the alarm 7 outside the electronic warning sign 3 will emit a buzzer alarm. At the same time, the alarm information is transmitted to the signal receiving device through Bluetooth, 4G / 5G network, or industrial wireless network. The signal receiving device transmits the information to the maintenance safety sign system through the network; the maintenance safety sign system notifies relevant personnel through broadcast or SMS push.
[0025] in 1 and Figure 2 In the figure, a glass plate 6 is arranged inside the cover plate 2, a card slot is arranged inside the limiting plate 401, a side of the card plate 402 away from the electronic warning sign 3 extends into the card slot, and two sliding slots are arranged inside the two limiting cylinders 403.
[0026] In this embodiment, the display information of the electronic warning sign 3 is conveniently observed through the glass plate 6 .
[0027] in 1 and Figure 3 In the embodiment, the two horizontal plates 404 are slidably connected to the two sets of slide grooves respectively, and two anti-slip grooves are provided inside the card plate 402. The two card blocks 405 extend from one side of the two horizontal plates 404 to the inside of the two anti-slip grooves respectively.
[0028] In this embodiment, the anti-slip mechanism 4 is provided, and the various structures of the anti-slip mechanism 4 cooperate with each other, thereby ensuring that the electronic warning sign 3 is placed stably, preventing unauthorized persons from accidentally touching it, and ensuring the safety of personnel and equipment.
[0029] in 2 and Figure 3In the figure, there are four limit springs 406 , which are divided into two groups. Each group of limit springs 406 has two limit springs. The opposite sides of the two groups of limit springs 406 are respectively connected to the opposite sides of the two transverse plates 404 .

[0033] To sum up, in the maintenance safety hanging system, when the electronic warning sign 3 needs to be hung during safety maintenance, the cover 2 is first opened, and the electronic warning sign 3 is placed in the protective box 1 of the corresponding equipment. At this time, the user pulls the pull rod 407 in opposite directions, and then the card plate 402 is inserted into the limit plate 401. When the card plate 402 is placed stably, the two pull rods 407 are released, and the limit spring 406 pushes the two card blocks 405 into the anti-slip groove, which initially ensures the stability of the electronic warning sign 3. Finally, the controller drives the two sets of electric push rods 408 to extend and drive the two card seats 409 to move in opposite directions, further fixing the electronic warning sign 3 to ensure the stability of the electronic warning sign 3. After the installation is completed, the cover is closed. Only when the maintenance is completed, the user uses the designated card remover to remove the electronic warning sign 3.
