DETAILED DESCRIPTION

[0016] In order to facilitate understanding of the utility model, the utility model will be described more fully below with reference to the relevant drawings. The preferred embodiments of the utility model are shown in the drawings. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0018] Please refer to Figures 1-5 , the structure schematic diagram of lightning protection joint type and part assembly provided by the utility model embodiment.

[0019] As shown in the figure, the utility model embodiment provides a lightning protection joint, and the lightning protection joint 100 includes a metal short pipe 1, an insulating outer layer 2, an anti-falling structure 3, a locking sleeve 4 and an insulating sleeve 5. One end of the metal short pipe 1 is a straight pipe, or a single clamping pressure socket, or a double clamping pressure socket, or a ring pressure socket, which can be connected with other pipelines through a joint. The other end of the metal short pipe 1 is provided with the anti-falling structure 3 on the outer wall in a ring shape, the insulating sleeve 5 is sleeved on the anti-falling structure 3, the locking sleeve 4 is sleeved on the outer wall of the insulating sleeve 5 and locks the insulating sleeve 5, and the insulating outer layer 2 is sleeved on the outer wall of the locking sleeve 4.

[0020] The anti-falling structure can adopt a conventional anti-falling structure, such as a convex point, a buckle, a thread, etc., and any existing design capable of achieving the anti-falling effect can be applied to the scheme of the utility model.

[0021] In a possible implementation, the locking sleeve 4 extends to one end of the metal short pipe 1 and is welded and fixed to the outer wall of the metal short pipe 1.

[0022] In a possible implementation, one end of the metal short pipe 1 is a straight pipe, or a single clamping compression socket, or a double clamping compression socket, or a ring compression socket, which can be connected with other pipelines.

[0023] In the utility model, one end of the metal short pipe is a straight pipe, or a single clamping compression socket, or a double clamping compression socket, or a ring compression socket, and the other end is processed to form an anti-falling structure (specifically a barb structure in the utility model), and the locking sleeve and the metal short pipe are welded together. Through the anti-falling structure, the function of buckling the insulating sleeve is well achieved. The insulating sleeve is inserted into one end of the metal short pipe with the anti-falling structure, and then a special tool is used to tightly lock the insulating sleeve with the locking sleeve, so as to ensure that the insulating sleeve has sufficient tensile strength and prevents the insulating sleeve from falling off.

[0024] In the utility model, when water penetrates into the insulating sleeve and the metal short pipe, conduction will be caused, the indoor equipment and facilities cannot be insulated and isolated from the outdoor metal pipeline, and thus lightning protection failure is caused. The rainwater is effectively prevented from penetrating into the insulating sleeve and the metal short pipe through the insulating outer sleeve. The indoor equipment and facilities are insulated and isolated from the outdoor metal pipeline, and the function of preventing lightning surge from invading the indoor equipment and facilities is achieved.

[0025] In specific assembly, the insulating sleeve is inserted into one end of the two groups of metal short pipes with the barb structure, and then a special tool is used to tightly lock the insulating sleeve with the locking sleeve, so as to ensure that the insulating sleeve has sufficient tensile strength, and then the insulating outer sleeve is sleeved, and is processed to be tightened, so as to ensure that rainwater cannot penetrate. The two ends of the lightning protection joint metal short pipe can be any one of a straight pipe, a double clamping compression socket, a single clamping compression socket or a ring compression socket, and the specification can be a commonly used outer diameter, which can be suitable for various connection modes, such as a double clamping compression joint, a single clamping compression joint, a ring compression joint, etc.
