Description

Technical Field

[0001] This utility model relates to an indicator sign, and more particularly to a double-sided power safety warning sign that can be quickly switched. Background Technology

[0002] When operators install, maintain, or repair equipment, it is often necessary to place warning signs such as "Do not turn on the switch, people are working" or "Do not operate, people are working" in the equipment operation area to prevent accidental start-up or misoperation of the equipment during operation and maintenance, which could cause safety hazards.

[0003] Based on this, hydropower stations currently use two methods to install safety warning signs. The first method involves placing the signs on the ground using stainless steel brackets, which facilitates the movement, positioning, and storage of the signs by workers. However, because these stainless steel brackets are not completely fixed after placement, they are easily blown over or displaced by the wind. Furthermore, when workers temporarily leave the maintenance area, other personnel may mistakenly assume that the equipment maintenance is finished and remove the signs directly, thus reducing the effectiveness of the safety warning signs.

[0004] The second method involves directly securing the safety warning signs to the protective netting or equipment supports around the maintenance area using cable ties or wire ropes. This external method prevents the signs from falling or shifting. While this method improves the securing effect compared to the first, it also increases the difficulty for workers to install and remove the signs, making it relatively cumbersome.

[0005] Furthermore, both types of safety warning signs mentioned above are movable structures, allowing workers to freely disassemble, assemble, and move them. While this structure offers good flexibility and ease of use, in locations requiring frequent or long-term operations, workers are often forced to repeatedly disassemble and move the safety warning signs, thus increasing their workload.

[0006] Therefore, there is a need for a safety warning sign that is both easy to fix and convenient to use. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] Example 1. A quick-switchable double-sided electrical safety warning sign, configured as follows: Figure 1-2 As shown, it includes a base 1. The lower end of the base 1 is fixed to the ground or external components by foot bolts or embedded parts. A turntable 2 is fixedly connected to the middle of the base 1. An indicator 3 is fastened to the turntable 2. Warning surfaces are formed on both the front and rear sides of the indicator 3. One warning surface is marked with instructions such as "Operation Prohibited" or "Close the Circuit Prohibited". The other warning surface is marked with normal use instructions such as "Normal Use" or "Close the Circuit Prohibited". The top two ends of the sign 3 are provided with hemispherical limiting grooves 4. A column 5 is fixedly connected to one side of the base 1. The upper end of the column 5 extends to the top of the sign 3 and is slidably connected to a fixing plate 6. One end of the fixing plate 6 extends to the top of the sign 3 and is fastened to the limiting groove 4 by a hemispherical limiting block. The other end of the fixing plate 6 is provided with a handle.

[0022] The turntable 2 is a manual turntable connected to the rotating base 1, which allows the operator to manually flip the indicator 3 during operation.

[0023] The fixing plate 6 and the column 5 are connected to each other by a first compression spring 7, and the two ends of the first compression spring 7 are fixed to the fixing plate 6 and the column 5 respectively.

[0024] The top of the column 5 is connected to a connecting rod 8. One end of the connecting rod 8 forms a baffle 801. The middle part of the connecting rod 8 is slidably connected to the fixing plate 6 via a cross-shaped sliding rod 802. The other end of the connecting rod 8 is threaded to the top of the column 5 via a stepped part.

[0025] The top of the turntable 2 is provided with a through placement groove 201, and the middle of the placement groove 201 is provided with an outward protruding locking block 202. The middle part of the indicator sign 3 is fastened and connected in the placement groove 201 and fastened and connected to the locking block 202 through the locking groove.

[0026] In this embodiment, the operator first lifts the fixing plate 6 upwards using the handle, then attaches the indicator sign 3 to the turntable 2, and rotates the indicator sign 3 using the turntable 2, so that one side of the indicator sign 3 faces outwards while the other side is hidden behind it, thus achieving a one-sided indicator function. After the indicator sign 3 is rotated into position, the operator immediately releases the handle, causing the fixing plate 6 to move downwards under the rebound of the first compression spring 7. The fixing plate 6 then engages with the limiting groove 4 at the top end of the turntable 2 via a limiting block, thereby limiting the indicator sign 3 using the cooperation of the fixing plate 6 and the first compression spring 7, preventing the indicator sign 3 from rotating or shifting normally in this state.

[0027] Based on this, when operators need to maintain the equipment in this area, they can flip sign 3 to the "Do Not Operate" side, thus providing a long-term and stable warning. After maintenance is completed, sign 3 is flipped to the "Normal Use" side, ensuring stable use of the equipment by other operators.
