[0002] Grounding rods are widely used in many fields such as communications, electricity, transportation, finance, petrochemicals, and building systems. During the installation of the grounding rod, a hammer is used to knock the grounding rod into the ground. This is one of the ways to install the grounding rod. During the knocking process, one person needs to hold the grounding rod, and the other person uses a hammer to knock the top of the grounding rod. During the knocking process, the hammer may not accurately hit the top of the grounding rod. There is a situation where the falling hammer injures the person's hand or the ear plate on the upper end of the grounding rod used to connect the grounding wire. The safety is poor, so it is necessary to design a lightning protection grounding wire grounding device that improves the safety of hammering the grounding rod. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a lightning protection grounding wire grounding device to solve the problems raised in the above-mentioned background technology. The utility model improves the safety of hammering a grounding rod into the ground using a hammer.

[0005] Furthermore, the lower surface of the cap tube is provided with a plurality of support rods equidistantly in a ring shape, the lengths of the plurality of support rods are different, the lower ends of the support rods are fitted with support blocks, the support blocks are fixed on the surface of the grounding rod, and the ear plates are inserted between two adjacent support rods.

[0006] Furthermore, a spring is installed on one side of the connecting tube away from the connecting head, one end of the spring is connected and fixed with a plug for sealing one end of the connecting tube away from the cap tube, and the plug is slidably installed in the connecting tube.

[0007] Furthermore, one end of the spring away from the plug is connected and fixed with a positioning plate, and the positioning plate is fixed on one side of the connecting tube close to the cap tube.

[0008] Furthermore, a limiting ring which is fixedly connected to the connecting head is sleeved on the connecting head, and a plurality of pin holes for inserting the extension rods are evenly opened on the outer surface of the limiting ring.

[0010] Furthermore, an end of the gripping rod away from the rubber sleeve is provided with an anti-slip sleeve, and the outer surface of the anti-slip sleeve is processed with finger grooves.

[0011] Beneficial effects of the utility model:

[0012] 1. Put the cap barrel on the top of the grounding rod, and then make the connecting barrel just above the ear plate, so that the personnel hold the grip rod, so that the connecting barrel plays the role of shielding the ear plate, and at the same time, the personnel's hands are away from the falling range of the hammer to prevent the hammer from hitting the personnel's hands or the ear plate when it is off-knock, thereby improving safety. During the hammering process, the hammer does not directly contact the grounding rod under the shielding of the cap barrel, thereby protecting the grounding rod.

[0013] 2.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] See also Figure 1 The utility model provides a technical solution: a lightning protection grounding wire grounding device, including a grounding rod 1, by connecting a fixed tip 2 at the lower end of the grounding rod 1, the resistance of the grounding rod 1 inserted into the ground is reduced, and by connecting a fixed ear plate 4 on the outer surface of the upper end of the grounding rod 1, the grounding rod 1 is conveniently connected to the grounding wire.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7A cap barrel 10 is sleeved on the upper end of the ground rod 1, and a connecting barrel 9 is connected and fixed to the outer surface of the cap barrel 10. The connecting barrel 9 is arranged directly above the ear plate 4. An internal thread is processed on the side of the connecting barrel 9 away from the cap barrel 10. A connector 8 is threadedly connected to the portion of the connecting barrel 9 where the internal thread is processed. An external thread matching the internal thread is processed at one end of the connector 8. A rubber sleeve 7 is installed at one end of the connector 8 away from the connecting barrel 9. A gripping rod 6 is connected and fixed to one end of the rubber sleeve 7 away from the connector 8. Ring sleeves 17 are connected and fixed to two parallel side surfaces of the rubber sleeve 7. The ring sleeves 17 and the rubber sleeve 7 are an integrally formed structure. One end of the gripping rod 6 and one end of the connector 8 are respectively pasted in two ring sleeves 17. The ring sleeves 17 increase the connection range between the rubber sleeve 7 and the gripping rod 6 and the connector 8.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The end of the gripping rod 6 away from the rubber sleeve 7 is sleeved with an anti-slip sleeve 5, and the outer surface of the anti-slip sleeve 5 is processed with finger grooves. The cap tube 10 is sleeved on the top of the grounding rod 1, and then the connecting tube 9 is placed just above the ear plate 4, so that the personnel hold the gripping rod 6, so that the connecting tube 9 plays the role of shielding the ear plate 4, and at the same time, the personnel's hands are away from the falling range of the hammer to prevent the hammer from hitting the personnel's hands or the ear plate 4 when it is off, thereby improving safety. During the hammer striking process, under the shielding of the cap tube 10, the hammer does not hit the ground straightly. The gripping rod 6 and the cap barrel 10 are assembled together, which is convenient for the separate storage of the gripping rod 6 and the cap barrel 10. When the cap barrel 10 is damaged, the cap barrel 10 can be replaced separately. At the same time, the rubber sleeve 7 can buffer the gripping rod 6 and prevent it from vibrating greatly during the hammering process, thereby improving the comfort of gripping.

[0028] See also Figure 1 , Figure 2 and Figure 6The lower surface of the cap barrel 10 is annularly provided with a plurality of support rods 11 at equal intervals. The lengths of the plurality of support rods 11 are different. The lower ends of the support rods 11 are fitted with the support block 3, and the support block 3 is fixed to the surface of the grounding rod 1, and the ear plate 4 is inserted between two adjacent support rods 11. After the cap barrel 10 is sleeved on the top of the grounding rod 1, the plurality of support rods 11 of different lengths on the cap barrel 10 respectively contact with the corresponding support block 3. Then, when the hammer strikes the cap barrel 10, the force applied to the cap barrel 10 is dispersed to multiple positions of the grounding rod 1 through the support rods 11 and the support block 3, so as to avoid the striking force generated by the hammer from acting completely on the top of the grounding rod 1. After the cap barrel 10 is inserted, the ear plate 4 is between two adjacent support rods 11, so that the relative position of the cap barrel 10 and the ear plate 4 remains unchanged, that is, the relative position of the connecting barrel 9 and the ear plate 4 remains unchanged, so that the connecting barrel 9 is always directly above the ear plate 4.

[0029] See also Figure 1 , Figure 3 and Figure 7 A spring 15 is installed on the side of the connecting tube 9 away from the connecting head 8, and one end of the spring 15 is connected and fixed with a plug 14 for blocking the end of the connecting tube 9 away from the cap tube 10. The plug 14 is slidably installed in the connecting tube 9, and the end of the spring 15 away from the plug 14 is connected and fixed with a positioning disk 16, so that the positioning disk 16 is fixed on the side of the connecting tube 9 close to the cap tube 10. After the assembly of one end of the spring 15 and the cap tube 10 is completed, the connecting head 8 is screwed into the connecting tube 9, and the connecting head 8 squeezes the plug 14, and the plug 14 squeezes the spring 15, so that the spring 15 produces elastic deformation. When the connecting head 8 is separated from the connecting tube 9, the spring 15 rebounds. Under the action of force, the plug 14 is moved back to the side of the connecting tube 9 away from the cap tube 10, so as to achieve real-time sealing of the part of the connecting tube 9 where the internal thread is processed, and prevent debris from entering the internal thread at will. A limiting ring 12 is provided on the connecting head 8 and is fixedly connected to the connecting head 8. When the connecting head 8 is screwed into the connecting tube 9, after the limiting ring 12 contacts with the connecting tube 9, the length of the connecting head 8 entering the connecting tube 9 is limited, and the spring 15 is prevented from being damaged by excessive extrusion. One end of the extension rod is inserted into one of the multiple pin holes 13 evenly opened on the outer surface of the limiting ring 12, so that the connecting head 8 can be screwed with the extension rod.
