Description

Technical Field

[0001] The utility model belongs to the technical field of bolt anti-dropping, in particular to an electric power bolt component of an electric power tower. Background Art

[0002] When electricity is now connected to power towers, bolts are usually used to fix them. When conventional bolts are used to connect power cables and power towers, since power cables are generally high and are greatly affected by wind, the long-term shaking of power cables under the action of wind drives the bolts to shake, which can easily cause the nuts to loosen, thereby causing the power cables to detach from the power tower, which in turn brings certain safety hazards.

[0003] In summary, the utility model therefore provides an electric bolt component of an electric power tower to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an electric bolt component of an electric power tower.

[0012] The utility model provides a first latching tooth and a second latching tooth. During the process of rotating the nut, after the inclined surfaces of the first latching tooth and the second latching tooth come into contact, a lateral thrust is generated to push the second latching tooth toward the inner side of the movable groove, so that the second latching tooth can continuously pass over the first latching tooth until the nut is locked. During this process, the second latching tooth is rebounded and reset by a provided spring, so that the second latching tooth is engaged with the first latching tooth. The nut is limited by the engagement of the first latching tooth and the second latching tooth, thereby preventing the nut from falling off.

[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] like Figure 1-4As shown, the utility model provides an electric bolt component of an electric power tower, comprising a bolt 1 and a nut 2, the nut 2 is hexagonal, a hexagonal head 3 is arranged at the bottom of the bolt 1, an external thread 4 is arranged on the top surface of the bolt 1, and the external thread 4 is used to realize the connection between the bolt 1 and the nut 2, and two slide grooves 5 are symmetrically arranged on the top surface of the bolt 1, and a plurality of first clamping teeth 6 are arranged in an array inside the slide groove 5, a connecting groove 7 is arranged at the center of the nut 2, and an internal thread 8 is arranged on the inner wall of the connecting groove 7, and the internal thread 8 is used to realize the connection between the nut 2 and the bolt 1, and a connecting ring 9 is rotatably installed at the bottom of the nut 2, two sliding blocks 10 are symmetrically arranged on the inner side of the connecting ring 9, and two movable grooves 11 are symmetrically opened inside the connecting ring 9, and movable blocks 12 are slidably installed inside the movable grooves 11, and one end of the movable block 12 is provided with a second clamping tooth 13, and the two second clamping teeth 13 are respectively passed through the ends of the two sliding blocks 10.

[0021] The upper surface of the first latching tooth 6 and the lower surface of the second latching tooth 13 are both inclined and parallel to each other. The inclined surface allows the connecting ring 9 to move only in one direction on the surface of the bolt 1, thereby preventing the nut 2 from loosening.

[0022] Among them, a spring 14 is installed inside the movable groove 11, and the two ends of the spring 14 are respectively against the side of the movable block 12 away from the second latch tooth 13 and the inner wall of the movable groove 11, so that the spring 14 realizes the self-rebound reset of the second latch tooth 13, thereby making the first latch tooth 6 and the second latch tooth 13 engage.

[0023] The inner diameter of the connecting ring 9 is larger than the diameter of the connecting groove 7 so that the bolt 1 can directly pass through the inner side of the connecting ring 9 .

[0024] The internal thread 8 and the external thread 4 are matched to facilitate the connection between the nut 2 and the bolt 1 .

[0025] The position of the slider 10 corresponds to that of the slide groove 5 , and the size thereof is adapted, so that the slider 10 can move in the slide groove 5 .

[0026] Specific working principle:

[0027] When the bolt 1 and nut 2 in the utility model are used, the nut 2 is first sleeved on the end of the bolt 1, and the slider 10 on the inner side of the connecting ring 9 is aligned with the slide groove 5. The nut 2 is rotated while the bolt 1 is kept stationary. Through the internal thread 8 in the connecting groove 7 of the nut 2 and the external thread 4 on the top of the bolt 1, the nut 2 will approach the hexagonal head 3 of the bolt 1 during rotation, so as to realize the connection between the bolt 1 and the nut 2. During the movement of the nut 2, after the inclined surfaces of the first latching tooth 6 and the second latching tooth 13 contact, a lateral thrust is generated to push the second latching tooth 13 to the inner side of the movable groove 11, so that the second latching tooth 13 can continuously pass over the first latching tooth 6 until the nut 2 is locked. In this process, the spring 14 is provided to realize the rebound reset of the second latching tooth 13, so that the second latching tooth 13 is engaged with the first latching tooth 6. The nut 2 is limited by the engagement of the first latching tooth 6 and the second latching tooth 13, so as to prevent the nut 2 from falling off, thereby improving the reliability of fixing the power cable and reducing the safety hazards caused by the loosening of the nut 2.
