In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] A convenient grounding device for a switch cabinet, such as Figures 1 to 5 As shown, a mounting groove 2 is opened on a cabinet panel 1 of a switch cabinet, and a grounding body 3 is installed in the mounting groove, wherein the mounting groove comprises a vertical main groove body 4, a horizontal upper stop groove body 5, and a horizontal lower stop groove body 6, wherein the upper stop groove body is located above the lower stop groove body, and one end of the upper and lower stop groove bodies are connected to the main groove body, and the other end is notched, and the lower end of the main groove body is notched; the grounding body is vertically arranged in the main groove body, and a socket 7 is provided at the top of the grounding body, and a limit rod 8 is provided at the upper end of the socket, and the limit rod is slidably matched with a vertical hole on the cabinet panel, and the lower end of the vertical hole is connected with the main groove body; the height of the upper stop groove body and the lower stop groove body in the vertical direction is greater than the thickness of the socket in the vertical direction; a grounding wire 9 is connected to the grounding body, and the grounding wire extends to the inside of the cabinet body 14 through the cabinet panel.

[0026] As needed, the grounding wire can be connected to the metal structure inside the cabinet to achieve the effect of safe discharge in emergency situations. The vertical holes on the cabinet board can be directly opened on the cabinet board body. In other optional schemes, if the thickness of the cabinet board of the cabinet is difficult to open a hole (in cooperation with the limit rod), a thickening structure (such as a thickened plate) can be provided on the cabinet board body, and the vertical hole can be opened on the thickening structure. It should be noted that the diameter of the limit rod is smaller than the main structure diameter of the grounding body. The limit rod only plays a limiting or guiding role, rather than serving as a load-bearing component. Therefore, a limit rod with a smaller diameter (even about 2-5mm) can meet actual use requirements.

[0027] Under normal circumstances, the holder is inserted into the upper stop groove, so that the grounding body is completely stored in the main groove. When in use, you only need to pull the holder out of the upper stop groove, and then press down or hammer the holder downward to insert the grounding body below the ground. During use, the holder is limited by the lower stop groove and will not move in the vertical direction. Therefore, the grounding body will not fall off the ground. In addition, the holder will not protrude too much from the surface of the switch cabinet, reducing interference.

[0028] The grounding body comprises a main structure 10 in the shape of a round rod, a tip 11 is provided at the lower part of the main structure, and a plurality of grounding rings 12 are provided at the lower part of the main structure near the tip. In an optional embodiment, an adjustment slot 13 is provided at the tip of the grounding body, and the lower end of the adjustment slot is notched. When the grounding body is inserted into the ground, if it encounters hard soil or bricks or stones, the adjustment slot is allowed to narrow, so as to facilitate the smooth insertion of the grounding body. In addition, the soil is embedded in the adjustment slot, which increases the contact area between the grounding body and the earth, and the grounding performance is better.

[0029] In an optional embodiment, the grounding ring occupies 3 / 4 of a circle in the circumferential direction of the grounding body and surrounds the grounding body by 270°, that is, a notch is provided on the grounding ring. When the grounding body is inserted into the ground, the grounding body is rotated by the socket and the socket is received in the lower stop groove. During this process, the grounding ring cuts the soil under the ground, which is similar to the effect of screwing a screw, and the grounding is more stable and reliable.

[0030] Usually, the length of the tip (along the length direction of the grounding body) is 1-3 cm. The card seat extends outward from the notch ends of the upper and lower stop slots, and the length of the notch ends extending outward is 0.5-1 cm. The total length of the grounding body is 3-10 cm.

[0031] The invention is to set a grounding body on the outside of the switch cabinet, and to store the grounding body on the cabinet surface, so that the operation is convenient and the grounding performance is reliable. When in use, it is only necessary to pull the card holder out of the upper stop groove, and then press down or hammer the card holder downward to insert the grounding body below the ground, and then the card holder can be pulled into the lower stop groove for storage, and the grounding body can be prevented from falling out of the ground during application. The grounding body can also be directly inserted into the ground as a whole according to actual needs, and the card holder is in contact with the ground surface. In this application mode, it is no longer necessary to insert the card holder into the lower stop groove.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
