Abstract
Description
Technical Field
[0001] The invention relates to the technical field of insulator iron caps, and in particular to an insulator iron cap. Background Art
[0002] As an insulator that plays multiple roles in high-voltage transmission and transformation lines, such as electrical insulation, mechanical connection, and carrying conductor load, it is of special importance in high-voltage and ultra-high-voltage transmission equipment systems. Insulators must be used in conjunction with iron caps, but the iron caps are prone to the problem of the foot ball falling out during use. Summary of the invention
[0003] Based on the technical problems existing in the background technology, the present invention proposes an insulator iron cap.
[0004] The invention provides an insulator iron cap, wherein a convex hole for installing a foot ball is arranged in the iron cap head, an inverted T-shaped hole connected with the convex hole is arranged on the iron cap head; a locking pin is arranged in the convex hole, and the locking pin is installed on the iron cap body by means of a spring so as to move up and down; matching threaded holes are arranged on the iron cap head and the locking pin, and when the locking pin is in an ascending state, the threaded hole on the iron cap head and the threaded hole on the locking pin correspond in position.
[0005] Preferably, the upper surface of the locking pin is provided with a groove matching the ball of the foot.
[0006] Preferably, the spring is a metal spring.
[0007] Preferably, the locking pin abuts against the inner wall of the convex hole.
[0008] The insulator iron cap proposed by the present invention can conveniently install the foot ball into the convex hole by pressing down the locking pin, and then loosen the locking pin, move the locking pin upward to cooperate with the iron cap head to limit the foot ball to prevent the foot ball from falling out of the iron cap head, and fix the locking pin by screws to ensure the stability of the foot ball installation.
[0009] The present invention can conveniently and quickly install the foot ball, and after the locking pin or the foot ball is worn, it is convenient to replace the locking pin and the foot ball, thereby reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a structural diagram of an insulator iron cap installed after the present invention is proposed;
[0011] Figure 2 This is a structural diagram of the insulator iron cap installation process proposed by the present invention. DETAILED DESCRIPTION
[0012] Reference Figure 1 , Figure 2The present invention provides an insulator iron cap, wherein a convex hole for mounting a foot ball 2 is provided in the head 1 of the iron cap, and the diameter of the narrow portion of the convex hole is larger than the cross-sectional diameter of the rod 21 of the foot ball and smaller than the diameter of the ball body 22 of the foot ball 2. Thus, after the foot ball 2 is mounted in the convex hole, the ball body 22 is supported, and the ball body 22 of the foot ball 2 can be fixed through the narrow portion of the convex hole, thereby fixing the foot ball 2.
[0013] An inverted T-shaped hole connected to the convex hole is provided on the iron cap head 1, so that the foot ball 2 can be placed in the convex hole through the inverted T-shaped hole. The minimum width of the inverted T-shaped hole is greater than or equal to the cross-sectional diameter of the foot ball's stem 21 and smaller than the aperture of the narrow part of the convex hole, so that the foot ball 2 can be conveniently placed in the convex hole through the inverted T-shaped hole, and after the foot ball 2 is installed, the inverted T-shaped hole can limit the foot ball 2 by supporting the ball of the foot ball to prevent the foot ball from falling out.
[0014] A locking pin 3 is arranged in the convex hole, and the locking pin 3 is installed on the iron cap body 5 so as to move up and down through a spring 4. When the locking pin 3 is moved downward, the foot ball 2 can be put into the convex hole through the inverted T-shaped hole, and then the locking pin 3 is released, so that the locking pin 3 rises and supports the foot ball 2, and the upper end of the ball 22 of the foot ball 2 enters the narrow part of the convex hole, so that the locking pin 3 cooperates with the iron cap head to limit the foot ball 2.
[0015] Matching threaded holes are provided on the iron cap head 1 and the locking pin 3. When the locking pin 3 is in the raised state, the threaded hole on the iron cap head 1 corresponds to the threaded hole on the locking pin 3. In this way, after the foot ball 2 is installed, the locking pin 3 in the raised state can be fixed by the screw 6 to prevent the locking pin 3 from moving down, thereby ensuring the reliable installation of the foot ball 2 and preventing the foot ball from falling out.
[0016] In this embodiment, the upper surface of the locking pin 3 is provided with a groove matching the ball of foot 2 to prevent the ball of foot 2 from shaking frequently in the convex hole after installation, thereby increasing friction loss.
[0017] In this embodiment, the spring 4 is a metal spring. The locking pin 3 abuts against the inner wall of the convex hole to prevent the locking pin 3 from shaking.
[0018] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
