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.

[0026] Example 1:

[0027] like Figures 1-5 As shown, the present invention provides a fastening device for anti-loosening bolts for power towers, including a base 1, a power tower base plate 2 is provided on the upper end surface of the base 1, a power tower body 3 is fixedly provided on the upper end surface of the power tower base plate 2, a fixing cap 4 is provided at each of the four corners of the upper end surface of the power tower base plate 2, and a fixing component 20 is provided on the upper end of the fixing cap 4.

[0028] The fixing assembly 20 includes a mounting plate 12, a spring 11, a connecting rod 9, and a pressure plate 8. The mounting plate 12 is provided at the upper end of the fixing cap 4, and the pressure plate 8 is provided inside the fixing cap 4. A circular groove 10 is opened on the upper end surface of the fixing cap 4, and the circular groove 10 passes through the fixing cap 4. The connecting rod 9 is provided inside the circular groove 10. One end of the connecting rod 9 is fixedly provided on the upper end surface of the pressure plate 8, and the other end of the connecting rod 9 is fixedly provided on the lower end surface of the mounting plate 12. A spring 11 is sleeved on the outside of the connecting rod 9. One end of the spring 11 is fixedly provided on the lower end surface of the mounting plate 12, and the other end of the spring 11 is fixedly provided on the upper end surface of the fixing cap 4.

[0029] Specifically, four screw holes 5 are provided at each of the four corners of the upper surface of the power tower base plate 2. Bolts 6 are provided at each of the four corners of the upper surface of the fixing cap 4, and the bolts 6 penetrate the fixing cap 4. The screw holes 5 and bolts 6 are matched, and screw holes 7 are provided inside the screw holes 5 and bolts 6, forming a threaded connection. The advantage is that the screw holes 5 and bolts 6 facilitate the placement of screw holes 7 inside them, thus allowing screw holes 7 to fix the fixing cap 4 to the power tower base plate 2.

[0030] Specifically, screw holes 13 are provided at the four corners of the upper surface of the base 1, and screw holes 14 are provided at the four corners of the upper surface of the power tower base plate 2. Screw holes 13 and 14 are located in the middle of the fixing cap 4, and screw holes 14 penetrate the power tower base plate 2. Screw holes 13 and 14 are matched with each other, and bolts 16 are installed inside screw holes 13 and 14. Bolts 16 are threadedly connected to screw holes 13 and 14. The advantage is that the screw holes 13 and 14 facilitate the placement of bolts 16 inside them, thereby allowing bolts 16 to fix the power tower base plate 2 onto the base 1.

[0031] Specifically, a washer 15 is provided between the lower end of the head of bolt 16 and the upper end of the base plate 2 of the power tower. The washer 15 is fitted onto the outside of the threaded rod of bolt 16, and an anti-loosening component 21 is provided on the upper end face of the washer 15. The advantage is that the washer 15 can increase the contact area, thereby reducing the pressure applied by bolt 16 to the surface of the base plate 2 of the power tower.

[0032] Example 2:

[0033] like Figure 1 , Figure 3 , Figure 5 As shown, this is an improvement on the previous embodiment. Specifically, the anti-loosening component 21 includes a serrated groove 17 and a serrated protrusion 18. The upper end face of the washer 15 has a serrated groove 17, and the lower end face of the bolt 16 has a serrated protrusion 18. The serrated groove 17 and the serrated protrusion 18 match each other. The advantage is that the serrated groove 17 and the serrated protrusion 18 can play an anti-loosening role for the bolt 16. When the bolt 16 is affected by vibration and rotates, the serrated protrusion 18 at its lower end moves towards the protruding part of the serrated groove 17. Under the influence of gravity, the serrated protrusion 18 slides down from the protruding part, thereby playing an anti-loosening role.

[0034] Specifically, a plurality of insertion rods 19 are fixedly installed on the lower end face of the base 1. The advantage is that the base 1 is inserted into the ground through the insertion rods 19, thereby providing support and fixation for the power tower base plate 2 and the power tower body 3.

[0035] During use, when installing the power tower, the base 1 is inserted into the ground using the insertion rod 19. The screw holes 14 on the base plate 2 are aligned with the screw holes 13 on the base 1. The base plate 2 is then fixed to the base 1 using washers 15 and bolts 16. The serrated grooves 17 and serrated protrusions 18 on the washers 15 and bolts 16 prevent loosening when the bolts 16 are vibrated and rotate. The lower end of the serrated protrusion 18 moves towards the protruding part of the serrated groove 17, and the serrated protrusion 18 slides down from the protruding part under the influence of gravity. After the base plate 2 of the power tower is installed, align the bolt 6 on the fixing cap 4 with the screw hole 5 on the base plate 2 of the power tower, and use the screw hole 7 to fix the fixing cap 4 on the base plate 2 of the power tower. At this time, the pressure plate 8 is moved upward by the pressure of the bolt 16, thereby driving the mounting plate 12 to move upward. At the same time, the spring 11 is stretched. After the installation is completed, the spring 11 is subjected to the rebound force and transmits the downward force to the mounting plate 12, the connecting rod 9 and the pressure plate 8 in sequence, so that the pressure plate 8 plays the role of pressing and fixing the bolt 16, thereby preventing the bolt 16 from loosening.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
