Background technique

The grounding rod, also known as the grounding pole, is embedded in the ground at one end to form a grounding system for electrical equipment. At present, there are many types of grounding rods, for example, easy-to-carry pull-out grounding rods, the grounding rod body is a multi-section structure; grounding rods with a rotating handle and grounding rod body with threads can be manually rotated into the ground; for It is easy to take out, and the threaded ground rod body is equipped with a ground rod with a mounting ring; the ground rod body is a ground rod with a polished rod. Each type of ground rod has its own advantages and disadvantages. For example, the pull-out ground rod is not suitable for insertion into the soil and cannot be widely used; the ground rod with a mounting ring and the rotating ground rod are not easy to be screwed in by manpower when the ground is hard. In soft soil, screwing in is also laborious, and it is not suitable for all kinds of soil; and it is only a bare rod, which is easy to accidentally injure the cooperating personnel who support the ground rod during the operation of knocking into the ground, and is not easy to pull out.

Utility model content

The technical problem to be solved by the utility model is to provide a ground rod, which is simple in structure, easy to manufacture, easy to operate, and easy to carry.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a grounding rod, including a grounding rod body and a handle, the handle is arranged on the top of the grounding rod body, and a terminal block and The auxiliary board is provided with a movable long rod, which is hinged with the auxiliary board, and the movable long rod can rotate in a vertical plane around the hinge point, and the wiring board and the auxiliary board are in the same vertical plane.

Further, the upper edges of the wiring board and the auxiliary board are on the same horizontal line.

Further, the hinge is a bolt flexible connection.

Further, there are two auxiliary plates, and the two auxiliary plates are welded in parallel to the diameter ends of the ground rod body, and the movable long rod is located between the two auxiliary plates, and is rotatably connected to the bolts passing through the two auxiliary plates.

Further, the lower end of the ground rod body is provided with a pointed portion.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the utility model is provided with a movable long rod, and when the grounding rod is driven into the ground, the operator can hold the movable long rod to keep the hands away from the drop point of the hammering, so as to avoid causing accidental injury to personnel; at the same time, when taking it out, it is also beneficial to pull out the grounding rod by holding the handle and the movable long rod at the same time; at the same time, the support function of the movable long rod is still giving an auxiliary force to the grounding rod body to prevent the grounding rod from tilting into the ground . When not in use, the movable long pole can be rotated and closed with the ground rod, which is easy to carry. Therefore, the structure is simple, the manufacture is easy, and the operation is simple and convenient, which not only facilitates driving the ground rod into the ground, but also facilitates taking it out, and avoids the potential safety hazard of accidental injury.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

At present, it is generally necessary to drive the grounding rod into the ground by hammering, and it is inevitable to need artificial support to make the grounding wire vertically enter the ground when driving in. Due to the hammering, it is inevitable to accidentally injure the hands of the supporter. cause unnecessary problems.

In order to solve this problem, the existing grounding rods have been improved, as shown in Figure 1-4 for details, including the grounding rod body 5 and the handle 1, the handle 1 is arranged on the top of the grounding rod body 5, and on the grounding rod body 5. One end close to the handle 1 is provided with a wiring board 6 and an auxiliary board 4. The auxiliary board 4 is provided with a movable long rod 3. The movable long rod 3 is hinged with the auxiliary board 4. The movable long rod 3 can be positioned in a vertical plane around the hinge point. Free rotation, but due to the restriction of the auxiliary board 4 in the horizontal plane, when the movable long rod 3 is rotated, the movable long rod 3 can drive the ground rod body 5 to rotate together in the horizontal plane, and the terminal board 6 and the auxiliary board 4 are in the same vertical plane , the wire 7 that needs to be grounded is connected on the wiring board 6, and the wiring board 6 is provided with a connecting terminal. When driving the grounding rod into the ground, the operator can hold the movable long rod 3 to keep the hands away from the drop point of the hammering, so as to avoid accidental injury to personnel; , is also conducive to the extraction of the grounding rod; at the same time, the supporting effect of the movable long rod 3 is still giving an auxiliary force to the grounding rod body 5, so as to prevent the grounding rod body 5 from tilting into the ground.

In a further technical solution, the upper edges of the wiring board 6 and the auxiliary board 4 are on the same horizontal line.

The hinged connection is a movable connection or a pin connection of bolts 2, and the structure is simple.

The auxiliary plates 4 are two pieces, and the two auxiliary plates 4 are welded in parallel to the two ends of the diameter of the ground rod body 5. The movable long rod 3 is located between the two auxiliary plates 4, and is connected to the bolts passing through the two auxiliary plates 4 in rotation. 2 on.

The lower end of the ground rod body 5 is provided with a pointed portion, which is convenient for driving the ground rod into.

The wiring board 6 and one of the auxiliary boards 4 can be integrated and welded on the ground rod body 5, and the other auxiliary board 4 is welded on the other side of the ground rod body 5 parallel to the auxiliary board.

The movable long rod 3 is hinged with the auxiliary plate 4. The movable long rod 3 can freely rotate around the hinge point in the vertical plane. When the ground rod is hammered into the ground, the movable long rod 3 can be rotated to support the ground rod and keep The distance of the knocker can effectively avoid accidental injury; and in the horizontal plane due to the limitation of the auxiliary plate 4, when the movable long rod 3 is rotated horizontally, the movable long rod 3 can drive the ground rod body 5 to rotate together in the horizontal plane, therefore, in the upper When pulling out the ground rod, you can hold the movable long rod 3 to rotate to the left and right, which drives the ground rod to also rotate, so that the gap between the ground rod and the soil layer increases, the friction decreases, and it is beneficial to pull out the ground rod.

The utility model is easy to carry, has a simple structure, is easy to manufacture, and is easy to operate. The utility model can not only facilitate the driving of the grounding rod into the ground, but also facilitate the removal, and avoid the potential safety hazard of accidental injury.
