Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grounding copper rods, in particular to a grounding copper rod. Background Art
[0002] The grounding wire is a wire directly connected to the earth, which can also be called a safety return line. When in danger, it transfers high voltage directly to the earth, which is considered a lifeline. Due to poor insulation performance or humid operating environment, household electrical appliances will cause a certain amount of static electricity on their shells, and in serious cases, electric shock accidents may occur. In order to avoid accidents, a wire can be connected to the metal shell of the appliance, and the other end of the wire can be connected to the earth. Once the appliance leaks electricity, the grounding wire will bring static electricity to the earth and release it. When the ground wire is grounded, a conductive metal rod will be inserted into the ground first, and then the ground wire will be connected to the metal rod. However, when the ground wire is connected to the metal rod, bolts are generally used to directly fix the ground wire to the grounding metal rod. However, this makes it easy for the bolts to fail to completely press the ground wire, resulting in an unreliable connection between the ground wire and the grounding metal rod. Utility Model Content

[0023] The utility model embodiment discloses a grounding copper rod, such as Figure 1-4 As shown, it includes a rod body 1, which is made of copper. Copper has strong corrosion resistance, is not easy to rust, has a long service life, and has high electrical conductivity. One end of the rod body 1 is integrally formed with a knocking portion 12, and the knocking portion 12 can facilitate the operator to knock the rod body 1 into the ground. At the same time, the end of the rod body 1 away from the knocking portion 12 is set in a conical shape, and the cone shape can increase the pressure of the rod body 1 in contact with the ground, which can reduce the physical exertion of the operator when inserting the rod body 1 into the ground. In addition, the circumferential surface of the rod body 1 is welded with a plurality of ribs 13 at intervals in the circumferential direction. In this embodiment, the number of ribs 13 is preferably six. The ribs 13 can not only increase the contact area between the rod body 1 and the ground, but also play the role of barbs, making the rod body 1 difficult to be pulled out. In addition, the side of the rib 13 away from the knocking portion 12 is set in an inclined surface, so that the rod body 1 can be better inserted into the ground.
[0024] In addition, a support rod 11 is welded to the circumferential surface of the rod body 1, and a connecting seat 2 is provided on the end of the support rod 11 away from the rod body 1. At the same time, a connecting portion 111 is integrally formed on the end of the support rod 11 away from the rod body 1, and a fixing plate 24 is integrally formed on the connecting seat 2. The fixing plate 24 is fitted with the connecting portion 111, and two fixing bolts 25 are threadedly connected between the fixing plate 24 and the connecting portion 111. The fixing plate 24 and the connecting portion 111 are connected using the fixing bolts 25, so that the connecting seat 2 can be fixed on the support rod 11. At the same time, a movable clip 22 is movably provided in the connecting seat 2 and a fixed clip 21 is welded thereto, and the ground wire is placed between the fixed clip 21 and the movable clip 22. At the same time, two clamping bolts 23 are threadedly connected to the connecting seat 2, and the ends of the clamping bolts 23 extend to the connecting seat 2 and are rotatably connected to the side wall of the movable clip 22. When the operator places the end of the ground wire between the fixed clip 21 and the movable clip 22, the two clamping bolts 23 are rotated, and the two clamping bolts 23 drive the movable clip 22 to move toward the fixed clip 21 until the movable clip 22 presses the ground wire against the fixed clip 21, so that the ground wire can be firmly fixed to the connecting seat 2, thereby electrically connecting the ground wire to the rod body 1.
[0025] In addition, multiple tooth edges 221 are integrally formed on the surfaces opposite to the fixed clip 21, and the tooth edges 221 can increase the friction between the fixed clip 21, the movable clip 22 and the ground wire, making the connection of the ground wire more secure. In addition, a baffle 222 is welded on the side of the movable clip 22. When the movable clip 22 and the fixed clip 21 are clamped on the ground wire, the baffle 222 abuts against the fixed clip 21, which can prevent the ground wire from jumping out of the gap between the fixed clip 21 and the movable clip 22.
[0026] The implementation principle of a grounding copper rod in an embodiment of the utility model is as follows: after the operator places the end of the ground wire between the fixed clip 21 and the movable clip 22, the two clamping bolts 23 are rotated, and the two clamping bolts 23 drive the movable clip 22 to move toward the fixed clip 21 until the movable clip 22 presses the ground wire against the fixed clip 21, so that the ground wire can be firmly fixed to the connecting seat 2, thereby electrically connecting the ground wire to the rod body 1.
[0027] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
