Abstract
Description
Technical Field
[0001] This utility model relates to the field of warning device technology, and in particular to a sign. Background Technology
[0002] During electrical maintenance, switching on and off, and other electrical operations, in order to prevent other personnel from accidentally closing the circuit breaker during the operation, it is necessary to place warning signs to warn other personnel and avoid accidental circuit connection, which could cause personal injury to the operator.
[0003] In current operations, warning signs are often placed on the ground at the switching system location, such as electrical cabinets, and removed after the operator completes the operation. However, due to factors such as on-site personnel movement, the warning signs on the ground are easily overlooked and are prone to movement. In locations with a large number of electrical cabinets, it becomes difficult to distinguish the warning location of the signs and whether the operator has completed the work. In such cases, dangerous actions such as accidental activation of the switch can still occur. In conclusion, the existing warning signs have limited warning effectiveness. Utility Model Content
[0004] The main purpose of this utility model is to provide a sign that aims to solve the problem of the limited warning effect of existing warning signs.
[0005] To achieve the aforementioned objective, this utility model provides a sign for the maintenance of electromechanical equipment, comprising:
[0006] The sign itself; and,
[0007] The limiting structure is provided on the sign body and includes two limiting arms arranged at intervals and a connector connecting one end of the two limiting arms. The other ends of the two limiting arms are arranged to protrude from the edge of the sign body and have elastic forces that keep them away from each other. The other ends of the two limiting arms are used to elastically abut against and limit the limit to the external gap.
[0008] In one embodiment, the limiting arm includes a first segment and a second segment arranged adjacent to each other, the first segment and the second segment being arranged at an angle along the extension direction of the limiting arm, the connector connecting the first segments of the two limiting arms, and the second segment being used to abut and limit to the external gap.
[0009] In one embodiment, the limiting arm has a protruding operating part, which is located outside the gap between the two limiting arms. Driving the operating part to move the limiting arm will cause it to move.
[0010] In one embodiment, the operating part is made of an insulating material.
[0011] In one embodiment, the limiting structure further includes an elastic element disposed between the other ends of the two limiting arms to drive the two limiting arms away from each other.
[0012] In one embodiment, the elastic element includes an elastic steel strip, the length of which is greater than the gap width between the two limiting arms.
[0013] In one embodiment, the other end of the limiting arm is bent along the direction opposite to the gap between the two limiting arms to form a clip and segment, which are used to extend into the external slot.
[0014] In one embodiment, an installation space is formed within the sign body, and the two limiting arms and the connector are at least partially disposed within the installation space.
[0015] In one embodiment, the mounting space includes a connecting segment for accommodating the connector;
[0016] The sign body is also provided with a key hole that connects to the installation space. The key hole is provided corresponding to the connecting section and is used to at least partially expose the connecting member. The key hole is used for the locking member to pass through.
[0017] In one embodiment, at least one of the outer sidewalls of the sign body is formed with a marking plane, and a warning sign is provided on the marking plane.
[0018] This utility model provides a sign with a limiting structure on its body. The limiting structure includes two spaced-apart limiting arms and a connector connecting the two limiting arms. The other ends of the two limiting arms protrude from the edge of the sign body. During use, the sign is hung inside an electrical operating device such as an electrical box. The elastic force of the limiting arms causes the two elastic arms to move away from each other, so that the other ends of the two limiting arms abut against the inner wall of the electrical operating device, thus confining the sign body within the external gap, i.e., inside the electrical box. After operation, the two elastic arms can be pressed together to remove the sign from the gap. This changes the sign placement from the ground to placement within the gap of a device where misoperation may occur, allowing other personnel to accurately know the warning location and whether the operation is complete, thus improving the warning effect of the sign.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0029] During electrical maintenance, switching on and off, and other electrical operations, in order to prevent other personnel from accidentally closing the circuit breaker during the operation, it is necessary to place warning signs to warn other personnel and avoid accidental circuit connection, which could cause personal injury to the operator.
[0030] In current operations, warning signs are often placed on the ground at the switching system location, such as electrical cabinets, and removed after the operator completes the operation. However, due to factors such as on-site personnel movement, the warning signs on the ground are easily overlooked and are prone to movement. In locations with a large number of electrical cabinets, it becomes difficult to distinguish the warning location of the signs and whether the operator has completed the work. In such cases, dangerous actions such as accidental activation of the switch can still occur. In conclusion, the existing warning signs have limited warning effectiveness.
[0031] Please see Figure 1 This utility model provides a sign 100 for the maintenance of electromechanical equipment. The sign 100 includes a sign body 1 and a limiting structure: the limiting structure is provided on the sign body 1 and includes two limiting arms 21 arranged at intervals and a connector 22 connecting one end of the two limiting arms 21. The other end of the two limiting arms 21 is arranged to protrude from the edge of the sign body 1 and has an elastic force that keeps them apart. The other end of the two limiting arms 21 is used to elastically abut and limit the sign to the external gap.
[0032] This utility model provides a sign 100, on which a limiting structure is provided. The limiting structure includes two spaced-apart limiting arms 21 and a connector 22 connecting the two limiting arms 21. The other ends of the two limiting arms 21 protrude from the edge of the sign body 1. During use, the sign 100 is hung in an electrical operating device such as an electrical box. The elastic force of the limiting arms 21 will cause the two elastic arms 21 to move away from each other, so that the other ends of the two limiting arms 21 abut against the inner wall of the electrical operating device, thus limiting the sign body 1 to the external gap, i.e., inside the electrical box. After the operation is completed, the two elastic arms 21 can be pressed together to remove the sign 100 from the gap. This changes the sign from being placed on the ground to being placed in the gap of a device where misoperation may occur, allowing other personnel to accurately know the warning location and whether the operation is completed, thus improving the warning effect of the sign.
[0033] Please see Figure 2 Furthermore, the limiting arm 21 includes a first segment 21a and a second segment 21b arranged adjacent to each other. The first segment 21a and the second segment 21b are arranged at an angle along the extending direction of the limiting arm 21. The connecting member 22 connects the first segment 21a of the two limiting arms 21, and the second segment 21b is used to abut and limit the arm to the external gap. In this embodiment, the limiting arm 21 includes the first segment 21a and the second segment 21b, so that the limiting arm 21 is bent, which allows for more limiting angles and avoids the limitation of only being able to be installed in a straight line into the external gap, thereby improving the applicability of the sign 100.
[0034] It should be noted that in this embodiment, the limiting arm 21 includes a first segment 21a and a second segment 21b arranged adjacent to each other. The limiting arm 21 may also include multiple segments to form more bending segments to suit different scenarios, and no further restrictions are made here.
[0035] On the other hand, an operating part 23 protrudes from the limiting arm 21. The operating part 23 is located outside the gap between the two limiting arms 21, and driving the operating part 23 to move the limiting arm. In this embodiment, during the process of removing the sign 100 from the external gap, it is necessary to drive the two limiting arms 21 inward to move closer to each other. Since the external gap, such as that of the electrical box, is small, the operating part 23 protrudes from the limiting arm 21 to facilitate operation by the operator. The operator only needs to operate the operating part 23 to drive the limiting arms 21 closer to each other.
[0036] It should be noted that the operating part 23 may be provided on only one of the limiting arms 21, or the operating part 23 may be provided on both limiting arms 21 at the same time, so as to facilitate operation.
[0037] Furthermore, the operating part 23 is made of an insulating material to prevent the accumulation of potential on the limiting arm 21, which could lead to electric shock when operating the operating part 23.
[0038] It should be noted that in this embodiment, the operating part 23 is an insulated handle to facilitate the operation of the limiting arm 21.
[0039] In this embodiment, the limiting arm 21 includes a first segment 21a and a second segment 21b, and the operating part 23 is disposed at the connection between the first segment 21a and the second segment 21b to drive the second segment 21b to move.
[0040] On the other hand, please see Figure 3 The limiting structure also includes an elastic element 24, which is disposed between the other ends of the two limiting arms 21 to drive the two limiting arms 21 away from each other. In this embodiment, relying on the elastic force between the two limiting arms 21 at the factory may result in a decrease in elastic force after repeated use, leading to insufficient clamping force. Therefore, the elastic element 24 is provided between the two limiting arms 21 to provide additional elastic force and improve the clamping effect of the limiting arms 21.
[0041] It should be noted that the elastic element 24 can be implemented in various ways, such as a spring, a sheet, etc., as long as it can provide an outward elastic force.
[0042] Specifically, the elastic element 24 includes an elastic steel strip, the length of which is greater than the gap width between the two limiting arms. In this embodiment, the length of the elastic steel strip is greater than the gap width between the two limiting arms. After the elastic steel strip is installed, it is bent to provide an outward thrust, causing the two limiting arms 21 to have a force that moves them away from each other. This design is simple, requires no custom-made springs or other components, and is easy to install.
[0043] It should be noted that the elastic steel strip is high-elasticity steel, which is a commonly used steel in the engineering field, and no specific model is limited here.
[0044] On the other hand, please see Figure 4 The other end of the limiting arm 21 is bent along the direction opposite to the gap between the two limiting arms 21 to form a clip and segment 21c, which is used to extend into the external slot. In this embodiment, relying solely on the frictional force of the other ends of the two limiting arms 21 for clamping still poses a risk of slippage. Therefore, the clip and segment 21c, extending into the external slot, fixes the position of the two limiting arms 21 and prevents the sign 100 from falling off.
[0045] It should be noted that the limit arm 21 has a cylindrical cross-section to facilitate its fit with the hole.
[0046] In addition, in this embodiment, the two limiting arms 21 and the connector 22 are integrally formed, which facilitates manufacturing.
[0047] In this embodiment, both the limiting arm 21 and the connecting member 22 are made of metal to facilitate molding and manufacturing, thereby reducing production costs.
[0048] On the other hand, an installation space is formed within the sign body 1, and the two limiting arms 21 and the connector 22 are at least partially disposed within the installation space. This protects the limiting structure from damage due to exposure and facilitates the installation of the limiting structure.
[0049] For further details, please refer to Figure 5 The installation space includes a connecting section for accommodating the connector; the sign body 1 also has a locking hole 11 communicating with the installation space, the locking hole 11 corresponding to the connecting section, for at least partially exposing the connector 22, and the locking hole 11 for a locking device to pass through. In this embodiment, the sign body 1 can be locked to an external housing component through the locking hole, further restricting changes in the posture of the sign body 1, preventing rotation or shaking of the sign body 1, which could lead to the sign 100 not being noticed in time.
[0050] On the other hand, at least one of the outermost walls of the sign body 1 is formed with a marking plane 12, and a warning sign is provided on the marking plane 12. In this embodiment, the marking plane and the warning sign facilitate other personnel to be aware of the warning content here.
[0051] It should be noted that the warning sign can be a pattern, text, etc., and there are no specific restrictions, as long as the operator and relevant personnel can understand the warning content. In this embodiment, the warning sign is the text "Do Not Close the Switch While People Are Working".
[0052] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
