[0002] The switch boxes of existing outdoor power equipment are generally installed at a height of more than two meters above the ground. When the power equipment needs to be maintained, it is necessary to open the power equipment and perform further operations on it. When the power equipment is maintained, inspected and operated, it is usually done manually by climbing to a height or holding an insulated operating rod to perform live operations.

[0003] The door of the existing power equipment is provided with a switch box, and the switch box is provided with a switch structure capable of opening the door of the power equipment. Figure 1 and Figure 2 As shown, the switch structure is arranged in a switch box 210, and an openable cover 240 is provided at the opening of the switch box 210. The switch structure includes a buckle assembly 220 that can move between an open position and a locked position, and a lock nose assembly 230 matched with the buckle assembly 220. The buckle assembly 220 can also rotate along a preset direction at the open position, thereby realizing the opening and closing of the door body of the power equipment; the free end 222 of the buckle assembly 220 has a lock nose fixing hole 221, and when the buckle assembly 220 is in the locked position, the lock nose assembly 230 is embedded in the lock nose fixing hole 221 of the free end of the buckle assembly 220, and the width of the free end 222 of the buckle assembly 220 is greater than the width of other parts of the buckle assembly 220. To turn on the electrical equipment, it is necessary to open the switch structure in the switch box. However, the operation is performed from 2 to 3 meters away, and the operating line of sight is limited. In addition, the switch structure of the power box is relatively complex, so the operation is difficult, especially at night when the line of sight is unclear. It is often necessary to repeat the operation again and again to complete an operation, resulting in high labor intensity and low operating efficiency. Summary of the invention

[0023] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the present invention after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0024] An embodiment of the present invention provides a tool for assisting in opening and closing a switch structure of an electric box. The tool matches the switch structure of the electric box and is used to open or close the switch structure. The switch structure includes a latch assembly 220 and a lock nose assembly 230 that cooperate with each other. The tool includes an insulating operating rod 150 and a tool body disposed at one end of the insulating operating rod 150. The tool body includes a first tool body 120 and a second tool body 110.

[0025] The first tool body 120 includes at least one shovel blade, which is used at least to open the cover plate 240 of the switch box and drive the buckle assembly 220 to move between the locked position and the open position.

[0026] Specifically, one end of the shovel blade is a fixed end, and the other end is a free end. The thickness of the free end of the shovel blade gradually increases in the direction approaching the fixed end, and at least one side surface of the shovel blade is an inclined surface inclined from the fixed end to the free end, that is, the thickness of the free end of the shovel blade is small and conical, so that the free end of the shovel blade can be inserted into the gap between the cover plate 240 of the switch box and the switch box body 210, thereby opening the cover plate 240.

[0027] Specifically, the portion of the shovel blade close to the free end is an arc-shaped structure, that is, it can be understood that the portion of the shovel blade close to the free end is bent, which can be C-shaped, wavy, etc.; setting the portion of the shovel blade close to the free end to an arc shape can be suitable for reducing the torque when operating the switch box at a long distance, and after opening the cover 240, the arc-shaped mechanism can hook the buckle assembly 220, thereby opening the buckle assembly 220 from the closed position to the open position.

[0028] Specifically, the orthographic projection of the portion of the shovel blade close to the free end is a trapezoid, which can be understood as the width of the portion of the shovel blade close to the free end gradually increases in a direction away from the free end.

[0029] Specifically, the first tool body may include a plurality of shovel blades, at least one shovel blade is used to be embedded between the cover plate and the switch box body and open the cover plate, and at least one shovel blade is used to hook the buckle assembly and pull the buckle assembly to an open position.

[0030] Specifically, the second tool body 110 includes four limiting plates connected in sequence (only two limiting plates facing each other may be provided), and the four limiting plates enclose a receiving cavity 111, and the receiving cavity 111 matches the buckle assembly 220 of the switch structure, and the buckle assembly 220 can penetrate into the receiving cavity 111 in a specific posture (for example, a lying posture) when the buckle assembly 220 is opened. By setting the sizes of the buckle assembly 220 and the receiving cavity 111, the buckle assembly 220 and the second tool body 110 can only generate relative translational motion or linear motion. When the buckle assembly 220 is located in the receiving cavity 111, the buckle assembly 220 will not rotate relative to the second tool body 110; alternatively, by providing a limiting or locking structure on the inner wall of the receiving cavity 111 (i.e., the inner side of the limiting plate), when the free end 222 of the buckle assembly 220 is introduced into the receiving cavity 111, the free end 222 of the buckle assembly 220 is engaged with the limiting or locking mechanism, and the buckle assembly 220 is temporarily connected to the second tool body, thereby driving the buckle assembly 220 to rotate to open the switch structure.

[0031] Specifically, the limiting or engaging mechanism may be a groove or convex structure arranged on the inner wall of the limiting plate or the inner wall of the receiving cavity.

[0032] Specifically, the limit plate constituting the second tool body can be a hard metal component or a plastic component, and a flexible elastomer can also be fixedly arranged in the accommodating cavity 111. The elastomer has a gap, and the width of the gap is smaller than the thickness or width of the buckle assembly. When the buckle assembly enters the gap in the elastomer in a straight line direction, the elastomer is elastically compressed, and the elastic compression is then reacted to the buckle assembly, thereby limiting the relative rotational movement of the buckle assembly in the elastomer, thereby achieving the second tool body driving the buckle assembly to rotate together.

[0033] Specifically, the first tool body and the second tool body can be fixedly disposed on one end of the insulating operating rod respectively, or the second tool body is fixed on the insulating operating rod, and the first tool body is fixed on the second tool body.

[0034] Specifically, the tool body is fixed on a connecting sleeve 140 via a connecting rod 130, and the connecting sleeve 140 is threadedly connected to the insulating operating rod 150; wherein, the connecting rod 130 can be a straight rod coaxially arranged with the insulating operating rod 150, or, the connecting rod 130 and the insulating operating rod 150 are arranged at an angle, and the angle between the connecting rod 130 and the insulating operating rod 150 is an obtuse angle; or, the connecting rod 130 can be an arc-shaped rod to facilitate the synchronous rotation with the buckle assembly over a long distance.

[0035] Specifically, a lighting assembly and a tester are also provided on the second tool body or the connecting rod 130. The insulating operating rod 150 is hollow inside, and the power supply of the lighting assembly can be provided inside the insulating operating rod 150. The lighting assembly and the tester can be purchased commercially, and their structures are not described in detail here.
