Description

Technical Field

[0001] This invention relates to the field of power switch hanging sign technology, and is a special tool for hanging signs on air switches. Background Technology

[0002] Currently, when implementing safety measures for circuit breakers in substations, it is necessary to hang warning signs on the circuit breakers. However, due to the small size of circuit breakers, hanging the signs is not easy; even after careful hanging, they are prone to falling off, and they also affect the opening of the protection panel doors. Furthermore, some circuit breakers cannot be hung at all due to installation reasons. Because the signs are relatively large compared to the circuit breakers, and circuit breakers are often installed in rows, hanging the signs can easily cover or obstruct the circuit breakers that should be hung next to them, resulting in unclear indications, affecting the judgment of staff, failing to provide a true safety warning, and easily causing accidental tripping of circuit breakers on other energized equipment, leaving a significant safety hazard. Summary of the Invention

[0003] This invention provides a special tool for hanging air switch signs, which overcomes the shortcomings of the prior art and can effectively solve the problems of existing signs being easy to fall off and difficult to operate.

[0004] The technical solution of the present invention is achieved through the following measures: a special tool for hanging air switch signs, comprising a vertical plate, a horizontal plate, a hook plate, a limiting plate, and a pulling device. The horizontal plate is fixed to the upper right side of the vertical plate. The middle part of the hook plate is hinged to the middle part of the vertical plate. The right end of the hook plate is fixed to the lower end of the limiting plate. The lower end of the pulling device is installed in the middle of the limiting plate. The upper end of the pulling device is installed on the right side of the horizontal plate, and the upper end of the limiting plate is pressed against the lower right side of the horizontal plate. The hook plate is tilted to the left.

[0005] The following are further optimizations and / or improvements to the above-mentioned technical solution: The aforementioned tensioning device is a tension spring or rubber band.

[0006] An operating handle is provided at the left end of the aforementioned vertical plate.

[0007] The hook plate and the limiting plate are integrally formed and form an angle of 30 to 60 degrees.

[0008] The vertical plate and the horizontal plate mentioned above are connected as a single unit.

[0009] The left end of the aforementioned hook plate has a hook tip.

[0010] This invention features a clever structural design and strong versatility, combining the functions of hanging a sign on the air switch handle and locking the air switch operating handle. It solves the problem of the air switch sign easily falling off after being hung, improves the reliability of safety measures, and prevents misoperation by maintenance personnel. Attached Figure Description

[0011] Appendix Figure 1 This is a schematic diagram of the main structure of the present invention.

[0012] The codes in the attached diagram are as follows: 1 is the vertical plate, 2 is the horizontal plate, 3 is the hook plate, 4 is the limiting plate, 5 is the pulling device, 6 is the operating handle, and 7 is the hook tip. Detailed Implementation

[0013] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0014] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0015] The present invention will be further described below with reference to embodiments and accompanying drawings: As attached Figure 1 As shown, the special tool for hanging safety signs on air switches includes a vertical plate 1, a horizontal plate 2, a hook plate 3, a limiting plate 4, and a tensioning device 5. The horizontal plate 2 is fixed to the upper right side of the vertical plate 1. The middle part of the hook plate 3 is hinged to the middle of the vertical plate 1. The right end of the hook plate 3 is fixed to the lower end of the limiting plate 4. The lower end of the tensioning device 5 is installed in the middle of the limiting plate 4. The upper end of the tensioning device 5 is installed on the right side of the horizontal plate 1, and the upper end of the limiting plate 4 is pressed against the lower right side of the horizontal plate 2. The hook plate 3 is tilted to the left. Depending on the actual needs, the tensioning device 5 can be a tension spring or a rubber band. The hook plate 3 is used to hang safety signs.

[0016] For ease of manual operation, an operating handle 6 is provided at the left end of the vertical plate 1. The hook plate 3 and the limiting plate 4 are integrally set and form an angle of 30 to 60 degrees, which helps to stabilize the safety sign. For ease of manufacturing, the vertical plate 1 and the horizontal plate 2 are integrally connected. The left end of the hook plate has a hook tip 7. The hook tip 7 further helps to stabilize the safety sign. The horizontal plate 2 cooperates with the limiting plate 4 to clamp the operating handle of the air switch; the horizontal plate 2 is located above the vertical plate 1 and has the function of locking the air switch operating handle, preventing the air switch handle from moving vertically and preventing accidental operation. A tension device 5 is provided between the horizontal plate 2 and the limiting plate 4 to tighten them, so that the limiting plate 4 firmly clamps the air switch handle and prevents the vertical plate 1 from falling off the air switch.

[0017] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
