Description

Technical Field

[0001] The utility model discloses a lightning protection grounding wire terminal pressing mechanism, belonging to the technical field of lightning protection grounding. Background Art

[0002] The grounding rod is designed and produced based on the theory of improving the internal conductivity of the grounding conductor and reducing the external soil resistivity of the grounding conductor. It is widely used in many fields such as communications, electricity, transportation, finance, petrochemicals, and building systems. The outside of the steel rod is hot-dip galvanized for corrosion protection to form a galvanized grounding rod. The upper end of the grounding rod is connected and fixed with a conductive plate, which is convenient for connecting the wire nose terminal and the grounding rod in a bolt-nut combination. That is, during the connection process, the bolt is passed through the wire nose terminal and the conductive plate in turn and then the nut is screwed on. In the process of tightening the fastener formed by the bolt and nut, the bolt head and nut will generate sliding friction with the conductive plate and the wire nose terminal, thereby damaging the galvanized layer on the surface of the conductive plate and the wire nose terminal, affecting the anti-corrosion performance of the grounding rod. Therefore, it is necessary to design a lightning protection grounding wire terminal clamping mechanism. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a lightning protection grounding wire terminal clamping mechanism to solve the problems raised in the above-mentioned background technology. The utility model prevents the bolts and nuts from directly contacting the surface of the conductive plate and the wire nose terminal, thereby protecting the galvanized layer on the surface of the conductive plate and the wire nose terminal.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a lightning protection grounding wire terminal clamping mechanism, including a grounding rod, a conductive plate is connected and fixed to the outer surface of the upper end of the grounding rod, a wire nose terminal is provided on one side of the conductive plate, a first through hole is opened on one side of the conductive plate, a second through hole aligned with the first through hole is opened on the outer surface of the wire nose terminal, a U-shaped plate is clamped on the conductive plate, one end of the wire nose terminal extends into the U-shaped plate, circular holes are opened on two parallel sides of the U-shaped plate, pipe sleeves are installed on two parallel sides of the U-shaped plate, the pipe sleeves are arranged concentrically with the circular holes, and the two pipe sleeves are respectively in contact with the wire nose terminal and the conductive plate, a bolt is inserted in the channel formed by the circular hole, the pipe sleeve, the second through hole and the first through hole, and a nut is threadedly connected to one end of the bolt, and the nut is arranged on the outside of the U-shaped plate.

[0005] Furthermore, a limiting ring for limiting the position of the bolt head is provided on the side of the U-shaped plate facing away from the nut, the bolt passes through the limiting ring, and a plurality of thin rods are equidistantly installed in a ring shape on the side of the limiting ring facing the U-shaped plate, and one end of the thin rods away from the limiting ring contacts the U-shaped plate.

[0006] Furthermore, a plurality of insertion holes cooperating with the thin rods are provided on a side of the U-shaped plate facing the limiting ring, and one end of the thin rod away from the limiting ring is inserted into the insertion hole.

[0007] Furthermore, a plurality of blind holes are equidistantly provided in a circular shape on one side of the limiting ring facing the U-shaped plate, and one end of the thin rod is connected and fixed in the blind hole.

[0008] Furthermore, a pointed head is connected and fixed to the lower end of the ground rod, and the pointed head and the ground rod are an integrally formed structure.

[0009] Furthermore, a disc head is connected and fixed to the upper end of the ground rod, and the diameter of the disc head is larger than the diameter of the ground rod.

[0010] Beneficial effects of the utility model:

[0011] 1. When the wire nose terminal and the conductive plate are connected by means of bolts and nuts, the U-shaped plate is clamped on the structure after the wire nose terminal and the conductive plate are connected, and the sleeve, the first perforation and the second perforation are aligned, and then the bolt is passed through the channel formed by the circular hole, the sleeve, the second perforation and the first perforation in sequence. At this time, the horizontal part of the U-shaped plate is in contact with the upper surface of the conductive plate, thereby preventing the U-shaped plate from rotating during the process of tightening the bolts and nuts. In the process of tightening the bolts and nuts, since the two sleeves are in contact with the wire nose terminal and the conductive plate respectively, the bolt head and the nut are not directly in contact with the wire nose terminal and the conductive plate, and in the process of tightening the bolts and nuts, the sleeve will not slide relative to the wire nose terminal and the conductive plate, thereby protecting the galvanized layer on the surface of the conductive plate and the wire nose terminal.

[0012] 2. During the assembly of bolts and nuts, the bolts are passed through the limiting ring, and the multiple thin rods installed on one side of the limiting ring are placed between the U-shaped plate and the limiting ring. Then, under the support of the structure formed by the limiting ring and the thin rods, a gap is created between the bolt head and the U-shaped plate. When the bolts and nuts cannot be disassembled by conventional means due to rust or other reasons, the gap between the limiting ring and the U-shaped plate can be used to cut off the bolts, thereby providing an alternative disassembly method for separating the wire nose terminal and the conductive plate.

A disc head 4 is connected and fixed at the upper end of the grounding rod 1. The diameter of the disc head 4 is larger than the diameter of the grounding rod 1. The disc head 4 increases the force-bearing area of ​​the upper end of the grounding rod 1, which is convenient for a hammer to hammer the grounding rod 1.

The design of the first through hole 13 and the second through hole 15 is convenient for inserting the bolt 6 connecting the conductive plate 8 and the wire nose terminal 7.

[0023] See also Figure 1-Figure 4, a U-shaped plate 3 is clamped on the conductive plate 8, one end of the wire nose terminal 7 extends into the U-shaped plate 3, circular holes 11 are opened on two parallel sides of the U-shaped plate 3, and pipe sleeves 10 are installed on two parallel sides of the U-shaped plate 3. The pipe sleeves 10 are arranged concentrically with the circular holes 11. The two pipe sleeves 10 are in contact with the wire nose terminal 7 and the conductive plate 8 respectively. A bolt 6 is inserted into the channel formed by the circular hole 11, the pipe sleeve 10, the second through hole 15 and the first through hole 13. A nut 2 is threadedly connected to one end of the bolt 6. The nut 2 is arranged on the outside of the U-shaped plate 3. When the wire nose terminal 7 and the conductive plate 8 are connected by the bolt 6 and the nut 2, the U-shaped plate 3 is clamped on the structure after the wire nose terminal 7 and the conductive plate 8 are connected, and the pipe sleeve 10. The first through hole 13 and the second through hole 15 are aligned, and then the bolt 6 is passed through the channel formed by the circular hole 11, the pipe sleeve 10, the second through hole 15 and the first through hole 13 in sequence. At this time, the horizontal portion of the U-shaped plate 3 is in contact with the upper surface of the conductive plate 8, thereby preventing the U-shaped plate 3 from rotating during the process of tightening the bolt 6. In the process of tightening the bolt 6 and the nut 2, since the two pipe sleeves 10 are in contact with the wire nose terminal 7 and the conductive plate 8 respectively, the head of the bolt 6 and the nut 2 are not directly in contact with the wire nose terminal 7 and the conductive plate 8, and in the process of tightening the bolt 6 and the nut 2, the pipe sleeve 10 will not slide relative to the wire nose terminal 7 and the conductive plate 8, thereby protecting the galvanized layer on the surface of the conductive plate 8 and the wire nose terminal 7.

The bolt 6 passes through the limiting ring 5. A plurality of thin rods 14 are installed in a plurality of blind holes equidistantly provided in a ring shape on the side of the limiting ring 5 facing the U-shaped plate 3. By installing one end of the thin rod 14 in the blind hole, the connection range between the thin rod 14 and the limiting ring 5 is increased. A plurality of plug holes 12 cooperating with the thin rod 14 are provided on the side of the U-shaped plate 3 facing the limiting ring 5, so that the end of the thin rod 14 away from the limiting ring 5 is inserted into the plug hole 12, so that the thin rod 14 and the U-shaped The plate 3 is plugged in. During the assembly of the bolt 6 and the nut 2, the bolt 6 is passed through the limiting ring 5, and the multiple thin rods 14 installed on one side of the limiting ring 5 are located between the U-shaped plate 3 and the limiting ring 5. Then, under the support of the structure formed by the limiting ring 5 and the thin rods 14, a gap is generated between the head of the bolt 6 and the U-shaped plate 3. When the bolt 6 and the nut 2 cannot be disassembled by conventional means due to rust or other reasons at a later stage, the bolt 6 can be cut off by utilizing the gap between the limiting ring 5 and the U-shaped plate 3, thereby providing an alternative disassembly method for separating the wire nose terminal 7 and the conductive plate 8.
