Description

Technical Field

[0001] The utility model relates to the technical field of bolt protection, in particular to an iron tower base bolt protection cover. Background Art

[0002] As an indispensable infrastructure in the power, telecommunications and other industries, the iron tower undertakes the important task of supporting and stabilizing the equipment. Among them, bolts, as one of the most basic components of the iron tower, bear the important role of connecting the iron tower and the equipment, so the safe operation and maintenance of the bolts are particularly critical. The material of the bolts requires high strength, corrosion resistance and fatigue resistance. Generally, high-quality alloy steel is selected to avoid the use of ordinary carbon steel. In addition, the bolts are prone to corrosion and need regular rust prevention and maintenance. During installation, it is necessary to use shockproof, anti-rust glue and other materials to cover the bolts to avoid corrosion. During use, it is necessary to regularly apply lubricating oil or rust inhibitor to the bolts to ensure the smoothness of the bolt surface and prevent corrosion. However, this installation and maintenance method requires regular inspection and maintenance by manpower, which is costly. Utility Model Content

[0005] Furthermore, the inner hole of the metal cap is larger than the outer diameter of the tower base screw and smaller than the inner diameter of the circular hole.

[0006] Furthermore, the hexagonal hole is smaller than the circular hole.

[0007] Furthermore, the anti-loosening nut and the mounting nut are both hexagonal nuts and have the same size as the hexagonal hole.

[0008] Furthermore, a cylindrical spring is connected between the spring sheets.

[0009] Furthermore, the size of the gasket and the spring sheet is smaller than the size of the hexagonal hole.

[0010] Furthermore, glue is injected into the gap between the circular hole and the metal cap.

[0011] The beneficial effects of the utility model are: 1) the utility model is connected with the stud on the tower base through the installation nut, and then the installation nut is pressed by the spring sheet and the anti-loosening nut sleeved on the stud to prevent it from loosening and coming off due to vibration. The upper end of the anti-loosening nut is a long metal cap, and the inner hollow part can accommodate a stud of a certain length. The outside is tightly connected with the rubber cap by glue, and the hexagonal hollow at the lower end of the rubber cap is buckled with the hexagonal bolt on the tower base, and then further tightly connected by glue, so that the hexagonal bolt of the tower base can be isolated from the outside world, and the tower base bolts are protected from corrosion.

[0017] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment: As shown in the figure, the utility model described in the utility model is a tower base bolt protection cover, including a rubber cap 1, one end of the rubber cap 1 is a dome 2, and the other end is provided with a connecting hole 3, the connecting hole 3 is composed of an upper and a lower part, the upper part close to the dome 2 is a circular hole 4, and the lower part away from the dome 2 is a hexagonal hole 5, and the connecting hole 3 is sequentially arranged with a metal cap 6, an anti-loosening nut 7, a spring sheet 8, a mounting nut 9 and a gasket 10 from top to bottom, the metal cap 6 is fixedly connected to the anti-loosening nut 7, the spring sheet 8 is located between the anti-loosening nut 7 and the mounting nut 9, and the anti-loosening nut 7 and the mounting nut 9 are separated from the spring sheet 8 by the gasket 10. The metal cap 6 is long in shape, and the length of the inner hole is used to accommodate the screw 11 of the tower base, so that the anti-loosening nut 7 and the mounting nut 9 can be adjusted to the installation position on the stud, so that they are tightly connected with the bolt 12 on the tower base, and then the mounting nut 9 is pushed up by the spring sheet 8, so that the mounting nut 9 cannot be detached upward, and then the bolt 12 on the tower base is supported to prevent it from loosening due to vibration, thereby improving the connection stability.

[0019] The inner hole of the metal cap 6 is larger than the outer diameter of the freewheeling base bolt 12 and smaller than the inner diameter of the circular hole. The hexagonal hole 5 is smaller than the circular hole 4. For easy installation, the rubber cap 1 can be sleeved on other parts from top to bottom, which is also convenient for the inner hole of the metal cap 6 to accommodate the freewheeling base bolt 12.

[0020] The anti-loosening nut 7 and the mounting nut 9 are both hexagonal nuts, and have the same size as the hexagonal hole 5 .

[0021] A cylindrical spring is also connected between the spring sheets 8. The elastic force of the spring sheets 8 can be improved by the cylindrical spring, and the structural strength of the spring sheets 8 can be reinforced.

[0022] The dimensions of the gasket 10 and the spring sheet 8 are smaller than the dimension of the hexagonal hole 5 .

[0023] Glue is also injected into the gap between the round hole and the metal cap 6. During installation, the rubber cap 1 and the metal cap 6 can be tightly connected by the glue. At the same time, after installation, the glue penetrates downward to the bolt 12 and the hexagonal hole 5, which can also tightly connect the bolt 12 and the rubber cap 1 and isolate them from the external environment, thereby preventing the bolt 12 from being corroded and ensuring the smoothness of the surface of the bolt 12.

[0024] The utility model is connected with the stud on the tower base through the installation nut, and then the installation nut is pressed by the spring sheet and the anti-loosening nut sleeved on the stud to prevent it from loosening and coming off due to vibration. The upper end of the anti-loosening nut is a long metal cap, and the inner hollow part can accommodate a stud of a certain length. The outside is tightly connected with the rubber cap through glue, and the hexagonal hollow at the lower end of the rubber cap is buckled with the hexagonal bolt on the tower base, and then further tightly connected through glue, so that the hexagonal bolt of the tower base can be isolated from the outside world, and the tower base bolts of the iron tower are protected from corrosion. At the same time, shock absorption can be used to prevent loosening, and the bolts can be isolated from the outside to extend their service life. The structure is simple and easy to use.
