[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-6 As shown, this utility model provides a composite anchor bolt, including a bolt body 1, a sealing gasket 3 fitted on the bolt body 1, a locking nut 2 threadedly installed on the bolt body 1, a protective cap 4 threadedly installed on the bolt body 1, a threaded hole 402 inside the protective cap 4, and the top end of the bolt body 1 threadedly inserted into the threaded hole 402 inside the protective cap 4. Fixing ears 401 are fixedly installed on both sides of the top end of the protective cap 4. The outer surface of the protective cap 4 is tapered. The bolt body 1 is a conventional composite anchor bolt, pre-embedded in a concrete base. Insert the bolt body 1 into the mounting hole on the tower base, then put on the sealing gasket 3 and tighten the locking nut 2. Then put the protective cap 4 on the bolt body 1 and tighten it through the fixing lug 401. The protective cap 4 can completely cover the bolt body 1, the locking nut 2 and the sealing gasket 3, which can prevent the bolt body 1 and the locking nut 2 from being corroded by rainwater, oxidation and other factors, thereby improving the service life of the anchor bolt and the stability of the power tower. The sealing gasket 3 can prevent rainwater from seeping into the bolt body 1 from the contact gap between the bottom of the protective cap 4 and the tower base.

[0020] A limiting component 5 is installed inside the bolt body 1. The limiting component 5 includes two mirror-distributed first limiting rods 501, which are slidably inserted into the bolt body 1. The ends of the two first limiting rods 501 that are close to each other are beveled. Fixing rods 505 are fixedly installed on both sides of the inside of the bolt body 1, and the fixing rods 505 are inserted through one end of the two first limiting rods 501. A first spring 506 is sleeved on both ends of the two fixing rods 505, and one end of the first spring 506 contacts the corresponding first limiting rod 501. An insert block 502 is inserted into the top of the bolt body 1. A rod 503 is fixedly installed on the lower surface of bolt body 1, and the bottom end of the rod 503 is tapered. Positioning slots 101 are provided on both sides of the top opening slot of bolt body 1. Positioning blocks 5021 are fixedly installed on both sides of the insert block 502, and the positioning blocks 5021 can be inserted into the corresponding positioning slots 101. Two symmetrically distributed second limiting rods 504 are slidably inserted into the insert block 502. A lever 5041 is fixedly installed at the end of each of the two second limiting rods 504 that are close to each other. A second spring 507 is fixedly installed in the insert block 502, and the second spring 507 is located between the two second limiting rods 504. Both sides of the inner side are provided with limiting grooves 102, and one end of the second limiting rod 504 can be inserted into the corresponding limiting groove 102. After tightening the locking nut 2, the two second limiting rods 504 can be slid and retracted into the insert block 502 by the lever 5041, and the second spring 507 is squeezed. Then, the insert block 502 and the insert rod 503 are inserted into the bolt body 1, so that the positioning block 5021 on the insert block 502 is inserted into the corresponding positioning groove 101. After the insert block 502 is fully embedded, the lever 5041 is released, and the rebound force of the second spring 507 is used to insert one end of the two second limiting rods 504 into the corresponding limiting groove 102. Within 02, the insert block 502 and the insert rod 503 are limited and fixed. When the insert rod 503 is inserted, the bottom end of the insert rod 503 is tapered and the first limiting rod 501 is inclined. The bottom end of the insert rod 503 separates the two first limiting rods 501, so that the two first limiting rods 501 slide away from each other and compress the first spring 506. The insert rod 503 is located between the two fixed rods 505 and does not contact the fixed rods 505 and the first spring 506. The ends of the two first limiting rods 501 that are far apart from each other extend out of the bolt body 1, which can limit the locking nut 2 and prevent the locking nut 2 from loosening due to vibration, etc.

[0021] Working principle: In use, the bolt body 1 is pre-embedded in the concrete base. The tower base can be installed on the base, and the bolt body 1 is inserted into the mounting hole on the tower base. Then, the sealing gasket 3 is put on, and the locking nut 2 is tightened. After tightening the locking nut 2, the two second limiting rods 504 can be slid and retracted into the insert block 502 by the lever 5041, and the second spring 507 is squeezed. Then, the insert block 502 and the lever 503 are inserted into the bolt body 1, so that the positioning block 5021 on the insert block 502 is inserted into the corresponding positioning groove 101. After the insert block 502 is fully embedded, the lever 504 is released. 1. The rebound force of the second spring 507 is used to insert one end of the two second limiting rods 504 into the corresponding limiting grooves 102 to limit and fix the insert block 502 and the insert rod 503. When the insert rod 503 is inserted, the tapered setting at the bottom end of the insert rod 503 and the inclined edge setting at one end of the first limiting rod 501 separate the two first limiting rods 501, so that the two first limiting rods 501 slide away from each other and squeeze the first spring 506. The ends of the two first limiting rods 501 that are away from each other extend out of the bolt body 1, which can limit the locking nut 2 and prevent the locking nut 2 from loosening due to vibration, etc.

[0022] Then, the protective cap 4 is placed on the bolt body 1 and tightened by the fixing lug 401. The protective cap 4 can completely cover the bolt body 1, the locking nut 2, and the sealing gasket 3, which can prevent the bolt body 1 and the locking nut 2 from being corroded by rainwater, oxidation, etc., thereby improving the service life of the anchor bolt and the stability of the power tower. The sealing gasket 3 can prevent rainwater from seeping into the bolt body 1 from the contact gap between the bottom of the protective cap 4 and the tower base.
