DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0019] like Figure 1-6 The utility model discloses a portable grounding rod, which comprises an upper rod head 1, a lower rod head 2, a grounding wire assembly 3 and a fixing assembly 4. The grounding wire assembly 3 comprises a first spring 5, a round ball 6 and a grounding wire connector 7. A hook 8 is installed on the upper rod head 1. A plurality of "I"-shaped grooves 9 are provided on one side of the hook 8. A groove 10 is provided in the middle of the plurality of "I"-shaped grooves 9. One end of the first spring 5 is installed in the groove 10. The round ball 6 is installed on the other end of the first spring 5. The grounding wire connector 7 is installed on the "I"-shaped groove 9, and a round ball groove 11 is provided on the grounding wire connector 7. The upper rod head 1 and the lower rod head 2 are connected to each other. The grounding wire can be fixedly connected through the fixing component 4; the grounding wire can be installed on the upper rod through the grounding wire component, and the grounding wire connector is installed in the "I"-shaped groove. The first spring in the groove makes the ball abut against the ball groove, so that the grounding wire connector is tightly connected to the "I"-shaped groove to prevent it from falling off. When removing it, press the ball to compress the first spring to make the ball disengage from the ball groove, and then the grounding wire connector can be removed, which is convenient for disassembly and assembly. Multiple groups of grounding wires can be quickly connected to each hook, which increases the cross-sectional area of ​​the grounding wire and can be applied to multiple voltage levels; the upper rod head and the lower rod head can be quickly disassembled and assembled through the fixing component, which is convenient for connecting different numbers of grounding rod sections, suitable for different voltage levels, easy to carry and easy to use.

[0020] The upper rod head 1 is provided with a round hole 12 inside, and the lower rod head 2 is provided with an insert rod 13 inside; the upper rod head 1 is provided with a clamping block 14, and the lower rod head 2 is provided with a bayonet 15; the installation is to insert the insert rod into the round hole, and the clamping block and the bayonet are engaged.

[0021] The fixing assembly 4 includes an outer hoop 16, a second spring 17 and a marble 18. The outer hoop 16 is sleeved on the outside of the upper rod head 1. A spring block 19 is provided inside the outer hoop 16 and outside the upper rod head 1. The second spring 17 is sleeved on the outside of the upper rod head 1, and one end of the second spring 17 is connected to the spring block 19 inside the outer hoop 16, and the other end is connected to the spring block 19 outside the upper rod head 1. The upper rod head 1 and the lower rod head 2 are correspondingly provided with a marble groove 20, and the marble 18 is installed in the marble groove 20 of the lower rod head 2 When the lower rod head is connected, the outer hoop is pressed upward to compress the second spring, and the outer hoop moves upward to expose the bottom of the upper rod head, making it easier to insert the insertion rod into the round hole and engage the clamping block with the bayonet. After the lower rod head is connected, the outer hoop is loosened, and the outer hoop moves downward under the action of elastic force, and presses one side of the marble into the marble groove in the upper rod head, so that the upper rod head and the lower rod head are tightly connected. When removing the lower rod head, the outer hoop is pressed upward to compress the second spring, and the outer hoop moves upward. At this time, the marble loses pressure and escapes from the marble groove of the upper rod head, and the lower rod head can be removed.

[0022] Working process:

[0023] The working principle of the utility model is as follows: the grounding wire can be installed on the upper rod head 1 through the grounding wire assembly 3, and the grounding wire connector 7 is installed in the "I"-shaped groove 9. The first spring 5 in the groove 10 makes the round ball 6 abut against the round ball groove 11, so that the grounding wire connector 7 is tightly connected with the "I"-shaped groove 9 to prevent it from falling off. When removing, press the round ball 6 to compress the first spring 5 to make the round ball 6 separate from the round ball groove 11, and then the grounding wire connector 7 can be removed, which is convenient for disassembly and assembly. Multiple groups of grounding wires can be quickly connected to each hook 8. When connecting the lower rod head 2, press the outer hoop 16 upward to compress the second spring 1 7. The outer hoop 16 moves upward and leaks out of the bottom of the upper rod head 1, making it easy to insert the insertion rod 13 into the round hole 12, and make the block 14 and the bayonet 15 engage with each other. After connecting the lower rod head 2, loosen the outer hoop 16, and the outer hoop 16 moves downward under the action of elastic force, and presses one side of the marble 18 into the marble groove 20 in the upper rod head 1, so that the upper rod head 1 and the lower rod head 2 are tightly connected. When removing the lower rod head 2, press the outer hoop 16 upward to compress the second spring 17, and the outer hoop 16 moves upward. At this time, the marble 18 loses pressure and escapes from the marble groove 20 of the upper rod head 1, and the lower rod head 2 can be removed.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
