Description

Technical Field

[0001] The utility model belongs to the technical field of lightning arrester leads, and in particular relates to a lightning arrester lead reinforcement structure. Background Art

[0002] After the lightning arrester lead of the collector line is exposed to wind and rain outdoors, it is easy to break at the wire joint. The traditional method is to replace the lightning arrester wire or wrap it with tape to increase the diameter of the lead, but the overall protection effect is general. In the later use, the breakage phenomenon still exists. Therefore, the existing method can only delay the breakage cycle of the lightning arrester lead, but cannot avoid the problem of breakage. Therefore, there are great limitations in practical applications and there is room for improvement. Utility Model Content

[0003] The purpose of the utility model is to provide a lightning arrester lead reinforcement structure to solve the problem of easy breakage of current lightning rod leads proposed in the above background technology, which cannot be solved by glue wrapping.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightning arrester lead reinforcement structure, which includes: a bellows, which is sleeved on the lead with a distance between the two; a spring, which is located between the bellows and the lead and is wrapped around the surface of the lead; the strength of the lead is enhanced by the spring to prevent the lead from breaking, and the bellows can completely separate the spring from the outside world to avoid the intrusion of rainwater and ensure that the spring will not rust due to water stains; connecting parts sleeved on the lead are also installed at both ends of the bellows, and the inner wall of the connecting part is against the surface of the lead, thereby achieving stable installation.

[0005] Preferably, a straight groove is provided in the middle of the bellows. Through the setting of the straight groove, the straight groove can be stretched open, so that the bellows can be unfolded and sleeved on the lead of the wound spring to wrap the lead. The outer surface of the bellows is also provided with a closed arc piece, one end of the closed arc piece is a fixed end, which is hot-melt connected to the bellows, and the other end of the closed arc piece is a free end, extending toward the straight groove and covering the straight groove, so as to ensure that after the bellows completes the sleeve on the lead, it can also ensure that there will be no water seepage or leakage.

[0006] Preferably, the inner wall of the sealed arc piece is completely fitted with the outer wall of the corrugated tube to ensure complete sealing, and the thickness of the sealed arc piece is equal to the thickness of the corrugated tube.

[0007] Preferably, the connector includes a mounting ring integrally provided at both ends of the bellows, the mounting ring having a notch, through which the mounting ring and the lead are sleeved and installed, and the inner diameter of the mounting ring fits the outer diameter of the lead.

[0008] Preferably, a locking groove is provided on the outer surface of the mounting ring, and a rubber ring is sleeved in the locking groove. The rubber ring can reduce the gap of the mounting ring and achieve tight contact between the mounting ring and the outer surface of the lead. The inner diameter of the rubber ring is smaller than the inner diameter of the lead. Therefore, when the rubber ring is sleeved on the mounting ring, a rebound force is generated to lock the mounting ring on the lead.

[0009] Preferably, a placement groove is provided on the inner wall of the mounting ring, in which a damping block is bonded. The damping block is in contact with the surface of the lead wire. When the mounting ring is subjected to the contraction force of the rubber ring, the entire mounting ring will squeeze the damping block. The damping block is tightly pressed against the surface of the lead wire, thereby increasing friction and achieving an anti-slip effect. At the same time, a sealing area is formed here to prevent external water from seeping into the mounting ring from here.

[0010] Preferably, one end of the spring extends beyond the outside of the lead, and a connector connected to the lightning arrester is installed at the end of the lead, wherein the connector is made of metal. One end of the spring extends and wraps around the connector, thereby protecting the soft lead end and avoiding breakage at this position.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Through the design of the utility model, adding a spring to the lead of the lightning arrester can not only improve the stability of the operation of the collector line, but also improve the service life of the lightning arrester. The installation of the spring on the lightning arrester requires little investment and is simple and convenient. It improves the shortcomings of the traditional method in practical applications. At the same time, the added bellows can separate the spring from the outside world, avoiding the problem of rusting of the spring due to rainy weather during long-term use, and further improving the service life of the spring.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 5 The utility model provides a technical solution: a lightning arrester lead reinforcement structure, the reinforcement structure includes:

[0023] The bellows 100 is sleeved on the lead wire 300 with a gap between them.

[0024] The spring 102 is located between the bellows 100 and the lead 300 and is wound around the surface of the lead 300. The spring 102 strengthens the lead 300 to prevent it from breaking. The bellows 100 completely isolates the spring 102 from the outside world, preventing it from being disturbed by rainwater and ensuring that the spring 102 will not rust due to water stains.

[0025] Connectors that are sleeved on the lead wire 300 are also installed at both ends of the corrugated tube 100 , and the inner wall of the connector abuts against the surface of the lead wire 300 , thereby achieving a stable installation.

[0026] In this embodiment, preferably, a straight groove 100a is provided in the middle of the bellows 100. Through the setting of the straight groove 100a, the straight groove 100a can be stretched open, so that the bellows 100 is unfolded and sleeved on the lead 300 of the winding spring 102, and the lead 300 is wrapped. The outer surface of the bellows 100 is also provided with a closed arc piece 101, and one end of the closed arc piece 101 is a fixed end, which is hot-melt connected to the bellows 100, and the other end of the closed arc piece 101 is a free end, extending toward the straight groove 100a and covering the straight groove 100a, so as to ensure that after the bellows 100 completes the sleeve of the lead 300, it can also ensure that there will be no water seepage or leakage.

[0027] In this embodiment, preferably, the inner wall of the sealed arc piece 101 is completely fitted with the outer wall of the bellows 100 to ensure complete sealing, and the thickness of the sealed arc piece 101 is equal to the thickness of the bellows 100 .

[0028] In this embodiment, preferably, the connecting part includes a mounting ring 200 integrally provided at both ends of the bellows 100, and the mounting ring 200 has a notch, through which the mounting ring 200 and the lead 300 are sleeved and installed, and the inner diameter of the mounting ring 200 fits the outer diameter of the lead 300.

[0029] In this embodiment, preferably, a locking groove 200a is provided on the outer surface of the mounting ring 200, and a rubber ring 201 is sleeved in the locking groove 200a. The rubber ring 201 can reduce the gap of the mounting ring 200 and achieve tight contact between the mounting ring 200 and the outer surface of the lead 300. The inner diameter of the rubber ring 201 is smaller than the inner diameter of the lead 300. Therefore, when the rubber ring 201 is sleeved on the mounting ring 200, a rebound force is generated to lock the mounting ring 200 on the lead 300.

[0030] In this embodiment, preferably, a placement groove 200b is opened on the inner wall of the mounting ring 200, and a damping block 202 is bonded in the placement groove 200b. The damping block 202 is against the surface of the lead 300. When the mounting ring 200 is under the contraction force of the rubber ring 201, the entire mounting ring 200 will squeeze the damping block 202. The damping block 202 is tightly pressed against the surface of the lead 300 to increase friction and achieve an anti-slip effect. At the same time, a sealing area is formed here to prevent external water from seeping into the mounting ring 200 from here.

[0031] In this embodiment, preferably, one end of the spring 102 extends beyond the outside of the lead 300, and a connector 301 connected to the lightning arrester is installed at the end of the lead 300, wherein the connector 301 is made of metal, and one end of the spring 102 extends and is wrapped around the connector 301, thereby protecting the end of the soft lead 300 to avoid breakage at this position.
