Description

Technical Field

[0001] This utility model belongs to the technical field of medium and high voltage high current disconnect switches, and specifically relates to a switchable power safety warning sign device. Background Technology

[0002] In the field of power safety sign technology, existing technologies generally adopt a single-function fixed design, with each sign only able to display one specific warning message (such as "Do not close the switch, people are working" or "Do not operate, people are working"). On-site deployment is achieved through rigid materials (such as PVC boards or aluminum plates) combined with fixed suspension structures (such as hanging ropes or magnetic strips).

[0003] In power production sites where both electrical and mechanical equipment are present, operators must carry multiple types of signage to meet diverse operational needs. However, existing technology has significant drawbacks:

[0004] Firstly, the limited functionality of signs leads to an increase in the number of signs carried, which can easily cause temporary relocation needs due to insufficient inventory or mismatch between the number carried, increasing the maintenance burden and the risk of omissions.

[0005] Secondly, when multiple types of signs coexist, they are prone to being mixed up or misused (such as confusing "Do Not Close the Circuit" and "Do Not Operate" signs). This not only reduces the accuracy of warnings, but may also lead to misoperation accidents due to incorrect labeling.

[0006] Third, traditional signs lack a dynamic switching mechanism and cannot adapt to changes in scenarios (such as switching from electrical equipment maintenance to mechanical maintenance). Different signs need to be repeatedly disassembled and reassembled, which prolongs the operation time, and frequent replacements exacerbate material wear.

[0007] Therefore, there is an urgent need to develop an intelligent signage system that integrates multi-functional switching, is lightweight and portable, and prevents misuse, in order to improve the efficiency and safety of power field operations. Utility Model Content

[0008] The purpose of this invention is to provide a switchable power safety warning sign device to address the above-mentioned shortcomings, thereby solving the problem of the single function of traditional power safety signs in the prior art.

[0009] This utility model is achieved through the following solution:

[0010] A switchable electrical safety warning sign device includes a first flip plate, a second flip plate, and a rotating connecting part; the rotating connecting part is located on one side of the first flip plate and the second flip plate, so that the first flip plate and the second flip plate can be flipped in both directions; at least two different warning signs are provided on the sides of the first flip plate and the second flip plate.

A second suspension hole is provided on both sides of the second embedded groove, and the second suspension hole is symmetrically arranged along the center of the second embedded groove. When the first flip plate and the second flip plate are magnetically locked, the positions of the first suspension hole and the second suspension hole are matched.

[0031] Example 1

[0032] like Figures 1-3 As shown, this utility model provides a technical solution:

[0033] A switchable electrical safety warning sign device includes, but is not limited to, a first flip plate 1, a second flip plate 2, and a rotating connecting part 3; the rotating connecting part 3 is located on one side of the first flip plate 1 and the second flip plate 2, enabling the first flip plate 1 and the second flip plate 2 to be flipped in both directions; at least two different warning signs are provided on the sides of the first flip plate 1 and the second flip plate 2.

[0034] Based on the above structure, the first flip plate 1 and the second flip plate 2 can be rotated in both directions by rotating the connecting part 3, so that different sides of the first flip plate 1 and the second flip plate 2 can be displayed. At the same time, at least two different warning signs are set on the first flip plate 1 and the second flip plate 2, which can enable the whole device to have more display functions, reduce the number of warning signs to carry, and reduce the difficulty of later handling.

[0035] As an example, the first flip plate 1 is provided with a first inner groove 11 at the end near the second flip plate 2, and the second flip plate 2 is provided with a second inner groove 21 at the end near the first flip plate 1. The first inner groove 11 and the second inner groove 21 are the same size, and the cavity structure formed by the combination of the first inner groove 11 and the second inner groove 21 can fix the main body of the rotating connection part 3.

[0036] Based on the above structure, by opening holes in the first flip plate 1 and the second flip plate 2, the rotating connection part 3 can be embedded between the two flip plates, reducing the overall size of the sign and making the overall structure more compact and easier to carry.

[0037] As an example, first rotating elongated holes 12 are provided on both sides of the first embedded groove 11, and the first rotating elongated holes 12 extend from the side wall of the first embedded groove 11 to the end of the first flip plate 1.

[0038] A second rotating elongated hole 22 is provided on both sides of the second inner groove 21. The second rotating elongated hole 22 extends from the side wall of the second inner groove 21 to the end of the second flip plate 2.

[0039] Based on the above structure, by setting the first rotating elongated hole 12 and the second rotating elongated hole 22, bidirectional flipping can be achieved in cooperation with the rotating connector, making the entire flipping process smoother.

[0040] As an example, the rotating connection part 3 may include a connecting body 31, a first rotating shaft 32 and a second rotating shaft 33; the connecting head is provided with a first rotating pin hole and a second rotating pin hole that are connected to the first rotating shaft 32 and the second rotating shaft 33; the first rotating pin hole and the second rotating pin hole are symmetrically arranged along the center of the connecting body 31.

[0041] The first rotating shaft 32 is disposed in the first rotating pin hole; the second rotating shaft 33 is disposed in the second rotating pin hole; the connection between the first rotating shaft 32 and the first rotating pin hole, and the connection between the second rotating shaft 33 and the second rotating pin hole are all clearance fits.

[0042] The first rotating shaft 32 is set through the first rotating elongated hole 12; the second rotating shaft 33 is set through the second rotating elongated hole 22.

[0043] Based on the above structure, the bidirectional flipping function of the first flipping plate 1 and the second flipping plate 2 is realized by setting the first rotating shaft 32 and the second rotating shaft 33 to cooperate with the first rotating elongated hole 12 and the second rotating elongated hole 22 respectively.

[0044] As an example, the contact portions of the connector 31 with the first inner groove 11 and the second inner groove 21 on both sides are set as arc structures 34;

[0045] Based on the above structure, by setting the two sides of the connector 31 as arc structures 34, it can facilitate flipping and avoid interference between the connector 31 and the first flip plate 1 and the second flip plate 2 during the flipping process, thereby causing damage to the flip plate; on the other hand, it can also prevent construction personnel from being scratched during use.

[0046] As an example, a first cavity 23 is provided at the end of the first flip plate 1 away from the first inner groove 11; a second cavity 35 is provided at the end of the second flip plate 2 away from the second inner groove 21; the distance from the end of the first cavity 23 to the first inner groove 11 is the same as the distance from the end of the second cavity 35 to the second inner groove 21; magnetic suction components are provided in the first cavity 23 and the second cavity 35.

[0047] Based on the above structure, by specially setting the positions of the first cavity 23 and the second cavity 35, the magnetic suction assembly can achieve magnetic locking before and after flipping, ensuring the stability of the signboard during use after flipping.

[0048] As an example, a neodymium iron boron magnet is provided in the first cavity 23, and a magnetically conductive steel sheet is provided in the second cavity 35. The first flip plate 1 and the second flip plate 2 are locked by the magnetic attraction between the neodymium iron boron magnet and the magnetically conductive steel sheet.

[0049] As an example, first hanging holes 24 are respectively provided on both sides of the first inner groove 11, and the first hanging holes 24 are symmetrically arranged along the center of the first inner groove 11. Second hanging holes 36 are respectively provided on both sides of the second inner groove 21, and the second hanging holes 36 are symmetrically arranged along the center of the second inner groove 21.

[0050] When the first flip plate 1 and the second flip plate 2 are magnetically locked, the positions of the first hanging hole 24 and the second hanging hole 36 are matched. This facilitates the hanging of the signboard later and reduces the difficulty of use.

[0051] As an example, when the first flip plate 1 and the second flip plate 2 are magnetically locked, a first warning sign is provided on the opposite end faces of the first flip plate 1 and the second flip plate 2; a second warning sign is provided on the opposite end faces of the first flip plate 1 and the second flip plate 2.

[0052] Alternatively, a first warning sign, a second warning sign, a third warning sign, and a fourth warning sign may be provided on the two sides of the first flip plate 1 and the second flip plate 2, respectively.

[0053] Based on the above structure, the signage can be displayed on two sides or one side depending on the actual usage. When two sides are required, two different signs can be set. When one side is required, four different signs can be set.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
