In order to realize the synchronous transmission between the first hinge member 401 and the second hinge member 402, preferably, one end of the first hinge member 401 is rotatably connected to the bottom wall of the accommodating blind hole 102, and when the second hinge member 402 drives the first hinge member 401 to move, the first hinge member 401 can swing along a rotation point to realize the abutment with the second unit 3 or the sidewall of the accommodating blind hole 102. The first articulation 401 can here preferably be connected in an articulated manner to a side wall or a bottom wall of the receiving blind hole 102, and the second articulation 402 can also be connected in the middle or at the end facing away from the pivot point of the first articulation 401.

Further, as shown in fig. 5, in order to increase the contact area between the ground wire 2 and the second unit 3 or the receiving blind hole 102 and ensure the connection stability between the ground wire 2 and the first unit 1 during the process of abutting the first hinge 401 against the second unit 3 or the receiving blind hole 102, as a preferred embodiment of the present invention, an abutting member 403 is disposed at one end of the first hinge 401 abutting against the second unit 3 or the receiving blind hole 102 to form a surface contact when the first hinge 401 abuts against the terminal or the receiving blind hole 102. Meanwhile, in order to improve the attaching degree, the attaching surface corresponding to the attaching member 403 may be set to be an arc surface adapted to the side wall of the terminal or the accommodating blind hole 102.

Preferably, when the first hinge member 401 presses the grounding wire 2 against the second unit 3 or the engaging surface of the receiving blind hole 102, in order to improve the fastening performance to the grounding wire 2, a pressing structure is provided on the surface of the engaging member 403 engaging the grounding wire 2, as shown in fig. 6. Because the grounding wire 2 has certain flexibility, the attaching piece 403 is provided with a part of area of the protruding structure, so that the grounding wire 2 can be fixed more effectively, the protruding structure can be a bead-shaped structure or a block-shaped structure, and different types or sizes of the protruding structure can be selected according to the type and material of the grounding wire 2.

Further, as a preferred embodiment of the present invention, the second unit 3 in the present application may be grounded for different types of power equipment, and during the process of grounding the power equipment by using the second unit 3, the types of the ground wires 2 of different power equipment may be different, in order to ensure effective contact between the ground wire 2 and the first unit 1, one or more accommodating grooves 304 are further formed on the side wall of the second unit 3 or the accommodating blind hole 102, the type of the accommodating groove 304 may be adjusted or set according to the type of the ground wire 2, different accommodating grooves 304 are respectively formed for the ground wires 2 of different specifications, and a plurality of notches of different types may also be formed in one accommodating groove 304, so as to increase the connection stability between the ground wire 2 and the first unit 1. Meanwhile, when the accommodating groove 304 is formed in the second unit 3, the ground wire 2 is tightly connected to the second unit 3 after being accommodated in the accommodating groove 304, and when the connection between the ground wire 2 and the second unit 3 is released, the ground wire 2 needs to be manually pulled out from the second unit 3.

Further, as a preferred embodiment of the present invention, in order to ensure the stability after the ground wire 2 is electrically connected to the first unit 1, it is also necessary to ensure good connectivity between the second unit 3 and the first unit 1. For this purpose, a fixing member 301 is disposed on a side of the second unit 3 facing the accommodating blind hole 102, and a connecting hole 101 matched with the fixing member 301 is opened on the accommodating blind hole 102. Since the movement direction of the second unit 3 is opposite when the ground wire 2 abuts against the second unit 3 and the blind accommodating hole 102, different types of fixing members 301 are required to be arranged according to the abutting condition of the ground wire 2.

Specifically, as shown in fig. 2, 3, and 4, when the ground wire 2 abuts against the second unit 3 to form an electrical connection, the sliding member 302 is disposed on the second unit 3, the sliding member 302 is sleeved on the second unit 3, and one end of the sliding member 302 away from the fixing member 301 abuts against the second unit 3, so that when the second unit 3 approaches towards the first unit 1, the second unit 3 can drive the sliding member 302 to slide towards the first unit 1, and further drive the first hinge member 401 to abut against the second unit 3; one end of the second hinge member 402 is connected to the sliding member 302, and the other end thereof is connected to the first hinge member 401, and the first elastic member 303 is sleeved on the second unit 3 between the sliding member 302 and the fixing member 301. Preferably, the fixing member 301 is provided in the form of a threaded post at this time, and a threaded groove matching with the fixing member 301 is formed in the coupling hole 101.

The working process of the grounding column is as follows: when electrical connection is required to be formed between the grounding wire 2 and the second unit 3, the fixing member 301 is screwed in a threaded cylinder manner, the second unit 3 gradually rotates downwards along the threaded groove, in order to avoid the second unit 3 and the first hinge member 401 from being locked by rotation, the sliding member 302 is sleeved on the second unit 3, the sliding member 302 preferably adopts a sliding sleeve, the sliding sleeve is abutted by the second unit 3 to move downwards, the sliding sleeve pulls the second hinge member 402, the second hinge member 402 adopts a rod-shaped structure, and the second hinge member 402 pulls the first hinge member 401 to swing together when the sliding block moves downwards. At this time, the first hinge member 401 rotates along the end portion hinged to the accommodating blind hole 102, and the end portion abuts against the second unit 3, and abuts against the ground wire 2 on the second unit 3, so that the ground wire 2, the second unit 3 and the first unit 1 are connected into a whole, and the electrical connection between the ground wire 2 and the ground post is ensured. When the grounding wire 2 and the second unit 3 need to be quickly disconnected, the second unit 3 is rotated and separated in the direction away from the first unit 1, the threaded column and the threaded groove are separated from each other, at the moment, the first elastic piece 303 begins to extend and drives the sliding piece 302 to move upwards, the second hinge piece 402 jacks the first hinge piece 401, so that the first hinge piece 401 is separated from the second unit 3, the grounding wire 2 is separated from the second unit 3, and the electrical communication between the first hinge piece 401 and the second unit 3 is released. Since the grounding column is mainly used to ensure effective grounding of the power equipment, the first elastic member 303 preferably adopts a spring structure, rather than an electrified structure.

As another preferred embodiment of the present invention, as shown in fig. 7, 8 and 9, when the ground wire 2 abuts against the sidewall of the accommodating blind hole 102 to form an electrical connection, a second elastic element 103 is disposed between the fixing element 301 and the connecting hole 101, the second elastic element 103 is used for driving the fixing element 301 to move in the axial direction of the second unit 3, and a baffle 104 for limiting the displacement distance of the fixing element 301 is disposed at the opening of the connecting hole 101. Preferably, because the first hinge part 401 abuts against the side wall of the accommodating blind hole 102 through the reverse elastic force of the second elastic part 103, in the actual use process, the elastic force of the second elastic part 103 is unstable, which results in the looseness between the first hinge part 401 and the accommodating blind hole 102, and the third elastic part 404 is further added between the first hinge part 401 and the accommodating blind hole 102, so that the first hinge part 401 is tightened to approach the side wall of the accommodating blind hole 102 through the third elastic part 404.

The working process of the grounding column is as follows: when the ground wire 2 needs to be abutted against the sidewall of the accommodating blind hole 102 to form an electrical connection, the second elastic element 103 pushes the fixing element 301 to a direction away from the connecting hole 101, the second unit 3 moves upward until the fixing element 301 is abutted against the baffle 104, the second unit 3 drives the first hinge element 401 to swing towards the sidewall of the accommodating blind hole 102, and the ground wire 2 is abutted against the sidewall of the accommodating blind hole 102, at this time, the ground wire 2 and the first unit 1 form an electrical connection. When the electrical connection between the ground wire 2 and the first unit 1 needs to be disconnected, the second unit 3 is pressed downwards, the fixing portion presses the second elastic member 103 downwards, the second unit 3 drives the second hinge member 402 to move, the first hinge member 401 swings towards the direction close to the second unit 3, and the ground wire 2 is separated from the side wall of the accommodating blind hole 102 and the electrical connection is released.

Preferably, in order to ensure the stability of the butt joint between the second unit 3 and the first unit 1 and prevent dust, impurities, rainwater and the like in the external environment from entering the accommodating blind hole 102, an end cover structure may be disposed at an opening end of the accommodating blind hole 102, and a through hole for the second unit 3 and the ground wire 2 to pass through is reserved at the end cover. When external impurities, rainwater and the like enter the accommodating blind hole 102, the bottom of the accommodating blind hole 102 is set to be in a conical surface form, the middle part is raised and inclined towards the periphery, and the side wall of the accommodating blind hole 102 is provided with a discharge hole so as to discharge the internal impurities and the rainwater

According to the grounding post in the embodiment of the invention, the second unit 3, the first unit 1 and the connecting piece 4 are used for realizing the quick connection and separation of the grounding wire 2 and the first unit 1, the complex connection mode of the original grounding wire 2 and the grounding post is eliminated, the second unit 3 can be used for connecting a plurality of grounding wires 2 according to the needs, the quick connection and separation of the grounding wires 2 and the grounding post can be realized, the integral structure is simple, the operation is convenient, and the connection and disconnection work of the grounding wire 2 and the grounding post is greatly simplified.

It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the present invention.
