Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power fittings, and particularly relates to a clamping fitting and a clamp-type lightning rod. Background Technology
[0002] Common lightning rods mainly consist of an air terminal, a down conductor, and a grounding electrode. The air terminal is typically made of round steel or round tubing. A clamp-type lightning rod is a special type of lightning rod with a unique installation structure. It primarily uses a clamp to hold the air terminal and fix it to the building requiring protection. A typical clamp consists of two semi-circular plates connected at the joint with screws, and the plates are pressed tightly against the outer surface of the air terminal with screws to secure it. Existing clamps of this type have a smooth surface contact with the air terminal. The clamps of clamp-type lightning rods are all made of metal, and metal itself is elastic. Over time, due to the elastic deformation of the clamp, the clamping force on the air terminal decreases, causing the air terminal to loosen and risk slipping. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a clamping fitting and a clamp-type lightning rod that can sustainably maintain the clamping stability of the lightning rod lightning arrester, effectively preventing the lightning arrester from loosening or falling off.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A clamping fitting includes two semi-circular clamping plates connected at both ends by screws. Elastic tabs are provided on both sides of the arc-shaped inner wall of the clamping plates, and multiple elastic tabs are provided along the arc-shaped trajectory of the clamping plates. The ends of the elastic tabs extend towards the middle of the clamping plate in the width direction, and there is a gap between the ends of the elastic tabs and the arc-shaped inner wall of the clamping plates. The ends of the elastic tabs have serrations.
[0006] A clamp-type lightning rod includes a lightning arrester and the aforementioned clamping hardware. One end of two clamping plates is connected to each other and is clamped onto a mounting plate. Bolts connecting the clamping plates pass through the mounting plate, which is used to connect and fix objects.
[0007] The beneficial effects of this utility model are as follows: the clamping hardware has long-term clamping stability for the lightning arrester, which can effectively prevent the lightning arrester from loosening and avoid the lightning arrester from slipping off. Attached Figure Description

[0013] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0014] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] Example 1: A clamping fitting includes two semi-circular clamping plates 1, with the two ends of the clamping plates 1 connected by screws. Elastic tabs 21 are provided on both sides of the arc-shaped inner wall of the clamping plates 1, and multiple elastic tabs 21 are provided along the arc-shaped trajectory of the clamping plates 1. The ends of the elastic tabs 21 extend towards the middle of the width direction of the clamping plates 1, and there is a gap between the ends of the elastic tabs 21 and the arc-shaped inner wall of the clamping plates 1. The ends of the elastic tabs 21 have serrations.
[0018] Preferably, the angle between the elastic piece 21 and the inner wall of the clamping plate 1 is 30°~60°, so as to avoid the elastic piece 21's expansion and contraction space being limited due to the angle being too small, thereby reducing the compression of the elastic piece 21; while the angle being too large will affect the smoothness of the elastic piece 21 when it is compressed into the clamping plate 1. If the angle is set to 80°~90°, the end of the elastic piece 21 will easily get stuck on the surface of the lightning arrester, thus affecting the normal installation of the lightning arrester.
[0019] As a preferred embodiment, the elastic sheet 21 and the clamping plate 1 are an integral structure. During manufacturing, they are integrally stamped and formed. Then, the elastic sheet 21 is bent towards one side of the clamping plate 1 by bending. After bending, the angle between the elastic sheet 21 and the clamping plate 1 is 30°~60°. Then, the clamping plate 1 is bent towards the elastic sheet 21 to form a semi-circular structure.
[0020] As an alternative, the elastic sheet 21 and the clamping plate 1 are stamped and formed separately, and then the elastic sheet 21 is fixed to both sides of the clamping plate 1 by welding, with the end of the elastic sheet 21 facing the inner arc of the clamping plate 1.
[0021] Preferably, the elastic plates 21 are arranged in pairs on both sides of the clamping plate 1 to ensure the balance of the pressure generated by the lightning rod on both sides of the clamping plate 1.
[0022] As a further preferred option, such as Figure 1 , Figure 2 As shown, the elastic tabs 21 arranged in pairs are integrally formed at both ends of the same metal strip 2. The elastic tabs 21 at both ends are bent towards the middle of the same side of the metal strip 2 at a bending angle of 30°~60°. The distance between the ends of the elastic tabs 21 at both ends is less than the width of the clamping plate 1, and the distance between the front ends of the elastic tabs 21 is greater than the width of the clamping plate 1. The metal strip 2 is located on the outer arc of the clamping plate 1, and the elastic tabs 21 at both ends are respectively clamped on both sides of the clamping plate 1. This method designs the elastic tabs 21 and the clamping plate 1 as a detachable structure. In specific use, the number of elastic tabs 21 can be adaptively selected according to the thickness of the lightning arrester. When the outer diameter of the lightning arrester is large, the number of elastic tabs 21 can be increased to improve the coverage of the circumference of the lightning arrester, thereby improving the clamping stability of the lightning arrester.
[0023] Preferred, such as Figure 1 , Figure 2 As shown, slots 11 are provided on both sides of the clamping plate 1. The elastic piece 21 and the bent part of the metal strip 2 are locked in the slots 11 to prevent the elastic piece 21 from sliding on the clamping plate 1, thereby preventing the lightning arrester from rotating in the clamping plate 1.
[0024] Example 2, combined with Figure 1 , Figure 3As shown, a clamp-type lightning rod includes a lightning arrester and the aforementioned clamping hardware. One end of two clamping plates 1 is connected to each other and is clamped onto a mounting plate 3. The bolts connecting the clamping plates 1 pass through the mounting plate 3. The mounting plate 3 is used to connect and fix objects, including but not limited to building exterior walls, columns cast inside buildings, etc.
[0025] Preferred, such as Figure 3 As shown, the lower end of the mounting plate 3 extends towards the bottom of the lightning arrester and is provided with a lower baffle 31. The lower baffle 31 is used to support the bottom of the lightning arrester to prevent the lightning arrester from falling.
[0026] During installation, first connect the mounting plate 3 to the fixed object, and connect one end of the two clamping plates 1 to the mounting plate 3. Insert the lightning arrester into the middle of the two clamping plates 1, and support the bottom of the lightning arrester on the lower baffle 31. Then tighten the bolts at the other end of the two clamping plates 1. During the tightening process, the end of the spring plate 21 contacts the surface of the lightning arrester and bends towards the clamping plate 1. After installation, the elasticity of the spring plate 21 will keep the lightning arrester pressed. Even if the clamping plate 1 is deformed, the elasticity of the spring plate 21 can be used to keep the pressure on the lightning arrester at all times, thereby preventing the lightning arrester from loosening.
[0027] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
