Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of warning signs and relates to a power outage warning sign for preventing misoperation. Background Art
[0002] Warning signs are a common and effective management tool used for warnings and reminders. Power outage warning signs are particularly important, but existing warning signs have the following problems: Typically, warning signs are hung on the switch cabinet with a string or glued to the switch cabinet, which can easily fall off, causing operators to mistakenly believe that maintenance is complete and then erroneously restore power, leading to safety accidents. Bolted signs, on the other hand, require drilling holes in the switch cabinet, creating safety hazards and making regular replacement and removal inconvenient. Furthermore, existing power outage warning signs only serve as warnings; power can still be restored without the sign removed, posing a significant safety hazard.
[0003] Therefore, a power outage warning sign that can prevent misoperation is designed to overcome the above problems. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a power outage warning sign that is simple and reasonable in structure, firm and reliable, and practical and convenient in preventing misoperation.
[0005] The utility model is realized through the following technical scheme: a power outage warning sign to prevent misoperation, comprising a warning sign installed on a switch cabinet, the warning sign consisting of a front plate and side plates arranged around the front plate, a text area is provided on the front plate, and the words "It is strictly forbidden to supply power when people are working" are provided in the text area, and the front plate and the surrounding side plates are spliced together to form a frame structure, and the frame structure is hollow inside, which is used to wrap the operating knob inside after the warning sign is installed to prevent misoperation of supplying power without removing the sign, and the frame structure is fixed to the switch cabinet by a fixing device.
[0006] Preferably, the fixing device is composed of four magnetic pillars arranged on the back of the front panel at the four corners of the front panel, one end of the magnetic pillar is fixedly connected to the back of the front panel, and a magnet is installed inside the other end. The front panel and the side panel are adsorbed on the iron shell of the switch cabinet through the four magnetic pillars with magnets.
[0007] Preferably, the fixing device is composed of fixing columns with hooks arranged at the four corners of the back of the front panel and hook slots arranged on the switch cabinet housing to match the four fixing columns. One end of the four fixing columns with hooks is fixed to the back of the front panel, and their sides are fixed to the side panels. The other end is provided with a hook, and the notches of the hook slots are all facing upward to facilitate the insertion or removal of the hooks.
[0008] Preferably, the side panel is a transparent panel, so that after the warning sign is installed, the state of the operating knob can be directly observed through the side panel without removing the warning sign.
[0009] Preferably, the side panels and the front panel are both made of insulating materials to prevent the switch cabinet from leaking electricity.
[0010] Preferably, an anti-slip layer is provided on the outer side of the side panel near the bottom to facilitate taking and prevent falling.
[0011] The beneficial effects of the utility model are as follows:
[0012] The anti-misoperation power outage warning sign designed by the utility model raises the height of the power outage warning sign as a whole so that the sign can cover the operating knob. If the power outage warning sign is not removed, the operating knob cannot be touched, thereby eliminating the misoperation behavior of supplying power without removing the sign. In addition, because the power outage warning sign is suspended by magnet adsorption or hooking instead of using a hanging rope to fix it, it will not fall off even if it is vibrated. The power outage warning sign can also be placed on the switch cabinet surface without a hanging point, and has a wider range of application than a hanging rope. BRIEF DESCRIPTION OF THE DRAWINGS
