[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the accompanying drawings.

[0026] An embodiment of the present utility model discloses a high-voltage electrical fitting for power lines.

[0027] The present utility model provides a high-voltage electrical fitting for power lines as shown in Figures 1-3 which includes a connection bin 1, a right hoop 2, a left hoop 4 and a thistle rack 5. The bottom of the connection bin 1 is fixedly connected to the right hoop 2. The side wall of the right hoop 2 is fixedly connected to a hinge 3. The other end of the hinge 3 is fixedly connected to the left hoop 4. The side wall of the left hoop 4 is fixedly connected to the thistle rack 5. A jack 6 is provided on the side wall of the connection bin 1. A buckle mechanism is provided in the cavity of the connection bin 1. The thistle rack 5 fits the right hoop 2 and the left hoop 4 through the buckle mechanism. After the thistle rack 5 is inserted into the jack 6 on the side wall of the connection bin 1, the thistle rack 5 is clamped by the reverse limit block 8, so that the right hoop 2 and the left hoop 4 are closed to realize the rapid installation of the line. Through the provided buckle mechanism, after the rod 9 is toggled, the reverse limit block 8 will slide downward, so that the thistle rack 5 becomes loose, realizing the rapid disassembly of the line, thus solving the problem of rapid installation and disassembly between the line and the electrical fitting.

[0028] In order to facilitate the rapid disassembly of the line, as shown in Figure 1 and 2As shown, the buckle mechanism includes an H-shaped support rod 7, a reverse limiting block 8, a clamping rod 9, and a wedge-shaped head 10. The H-shaped support rod 7 is fixedly connected to the cavity of the connection bin 1. A reverse limiting block 8 is rotatably connected to the rod wall of the H-shaped support rod 7. The reverse limiting block 8 is clamped with the thorn-shaped rack 5. A clamping rod 9 is slidably connected to the inner side wall of the cavity of the connection bin 1. One end of the clamping rod 9 is fixedly connected with a wedge-shaped head 10, and the other end of the clamping rod 9 extends outside the connection bin 1. By using the arranged clamping rod 9 and wedge-shaped head 10, the reverse limiting block 8 rotating on the rod wall of the H-shaped support rod 7 can be fixedly supported, so that the reverse limiting block 8 clamps and limits the thorn-shaped rack 5. And after the clamping rod 9 is pulled out, the reverse limiting block 8 will rotate downward, so that the thorn-shaped rack 5 becomes loose, realizing the quick disassembly of the circuit.

[0029] In order to reset the buckle mechanism after it is pulled out, as Figure 1 shown, a spring 11 is clamped on the rod wall of the clamping rod 9. One end of the spring 11 is fixedly connected to the side wall of the connection bin 1. By using the arranged spring 11, after pulling out and releasing the hand, the spring 11 drives the clamping rod 9 to rebound, and the wedge-shaped head 10 will squeeze the reverse limiting block 8, so that the reverse limiting block 8 is extruded upward, facilitating the next installation.

[0030] In order to limit the thorn-shaped rack 5, as Figure 1 shown, the side wall of the reverse limiting block 8 is provided with teeth opposite to the teeth on the side wall of the thorn-shaped rack 5. By using the arranged reverse limiting block 8, the teeth on the side wall of the reverse limiting block 8, which are opposite to the teeth on the side wall of the thorn-shaped rack 5, are used to limit and fix the thorn-shaped rack 5.

[0031] And in order to support the reverse limiting block 8, as Figure 1 shown, the wedge-shaped head 10 is a trapezoidal connecting block. The wedge-shaped head 10 is slidably connected to the bottom of the reverse limiting block 8. By using the wedge-shaped head 10 arranged as a trapezoid, under the extrusion of the reverse limiting block 8, the reverse limiting block 8 can be rotated upward, facilitating the limiting and fixing of the thorn-shaped rack 5.

[0032] Finally, in order to prevent the circuit from swinging, as Figures 1-3 shown, the bottom of the connection bin 1 is fixedly connected with an installation base plate 12. By using the arranged installation base plate 12, it can prevent the circuit from driving the connection bin 1 to shake and affect the normal construction.

[0033] Working principle:

[0034] During installation, pull the clamping rod 9 to open and close the right clamp 2 and the left clamp 4. Place one end of the line between the right clamp 2 and the left clamp 4, and then close the right clamp 2 and the left clamp 4. The thorn rack 5 on the side wall of the left clamp 4 will insert into the socket on the side wall of the connection chamber 1. Release the clamping rod 9, and the reverse limiting block 8 in the cavity of the connection chamber 1 will be squeezed and rotated upward. The reverse limiting block 8 will limit the thorn rack 5 and fix the right clamp 2 and the left clamp 4. During disassembly, pull the clamping rod 9 to rotate the reverse limiting block 8 downward, the thorn rack 5 becomes loose, and rotate the left clamp 4 upward to take out the line, thus realizing rapid installation and disassembly.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
