[0011] Compared with the prior art, the insulating double-head hook rod of the utility model has the following beneficial effects:

[0012] 1. In view of the problem that there is no reliable fixing measure between the overhead line and the lead wire during the live connection of the distribution network in the existing insulating rod operation method, the lead wire is easily dropped during the connection process, causing a phase-to-phase short circuit or grounding fault.

In addition, the positioned lead wire can enter the space between the hook and the baffle, avoiding the situation where the lead wire stays at the intersection of the two baffles and is separated from the inner cavity of the hook when subjected to external force. The fixation of the lead wire is safer and more reliable, and the insulating rod body and the two hooks can flexibly form a "C" type or "Z" type structure, which can be adapted to the positioning support between the overhead line and the lead wire that are staggered up and down.

DETAILED DESCRIPTION

[0022] The following is a combination of specific implementation cases and attached Figures 1 to 5 The present invention is further described below, but the present invention is not limited to these embodiments.

[0023] In view of the problem that there is no reliable fixing measure between the overhead line and the lead wire during the live connection of the distribution network in the existing insulated pole operation method, it is easy to cause the lead wire to fall during the connection process, causing phase-to-phase short circuit or grounding fault, refer to Figures 1 to 5 As shown, an insulating double-head hook rod is proposed, including an insulating rod body 1, the outer wall of the insulating rod body 1 is coated with an epoxy resin coating to ensure that the insulating rod body 1 can be insulated when in use, so as to ensure the safety of workers when using it, and the upper and lower ends of the insulating rod body 1 are respectively detachably provided with hooks 2, and the inner wall of each hook 2 is symmetrically provided with two baffles 18, and the two baffles 18 are gathered from the opening of the hook 2 to the inner cavity of the hook 2. A relatively closed space is formed with the hook 2 through the two baffles 18, so that the overhead line and the lead wire can enter the space to realize positioning, and the upper and lower ends of the insulating rod body 1 are respectively provided with A connecting seat 3 is provided, and a cavity 4 is formed on the outer wall of the connecting seat 3. The cavity 4 is formed along the arc-shaped outer wall of the connecting seat 3. The inner cavity of the cavity 4 is rotatably connected to a rotating seat 7 through a pin shaft. The rotating seat 7 can rotate left and right along the cavity 4. The rotating seat 7 is rotated and positioned in the inner cavity of the cavity 4 through a positioning component. The rotating seat 7 can be positioned after rotation through the positioning component to ensure the stability of the rotating seat 7 in the inner cavity of the cavity 4. The rotating seat 7 is connected to the hook 2 through a connecting component. The hook 2 can be installed or disassembled between the rotating seats 7 through the connecting component to perform regular maintenance and replacement of the hook 2.

[0024] Specific reference Figure 3 and Figure 4 As shown, the positioning component includes three positioning seats 5 circumferentially arranged on the inner wall of the cavity 4, and the angle between each adjacent positioning seats 5 is equal. In the present embodiment, the angle between the positioning seats 5 is set to 90 degrees. The outer wall of each positioning seat 5 is respectively provided with a positioning groove 6. A spring 8 is installed in the inner cavity of the rotating seat 7, and the spring 8 can push the moving rod 9 to telescopically move along the inner cavity of the rotating seat 7. The outer wall of the spring 8 is provided with a moving rod 9, and the moving rod 9 extends outward from the inner cavity of the rotating seat 7. A hemisphere 10 is installed on the outer wall of the moving rod 9. The hemisphere 10 is embedded in the inner cavity of one of the positioning grooves 6. By embedding the hemisphere 10 in the inner cavity of the positioning groove 6, the position of the rotating seat 7 and the moving rod 9 can be positioned, thereby ensuring that the position of the hook 2 connected to the top of the moving rod 9 is stable after rotation; refer to Figure 4As shown, the shape of the positioning groove 6 is adapted to the shape of the hemisphere 10, and the elastic force of the spring 8 causes the hemisphere 10 on the outer wall of the moving rod 9 to be embedded in the inner cavity of the positioning groove 6, so that the hemisphere 10 can be stably positioned in the inner cavity of the positioning groove 6; in addition, a square block is installed on one side of the moving rod 9 extending into the inner cavity of the rotating seat 7, and the inner cavity of the rotating seat 7 is set to be a square cavity adapted to the square block. The square block installed on the outer wall of the moving rod 9 moves along the square cavity of the rotating seat 7, which can prevent the moving rod 9 from rotating relative to the rotating seat 7 to ensure the accuracy of the displacement direction of the moving rod 9.

[0025] See also Figure 3 and Figure 5 As shown, the connecting component includes a connecting piece 11 installed on the top of the moving rod 9, a threaded seat 12 is installed on the top of the connecting piece 11, a limiting sleeve 13 is installed on the top of the threaded seat 12, and the hook 2 is inserted into the inner cavity of the limiting sleeve 13, the limiting sleeve 13 is set to be an elastic body with elastic deformation ability, and the limiting sleeve 13 is set to expand outward from bottom to top, and the top of the limiting sleeve 13 is tightened by external force, so that the clamping positioning of the hook 2 in the inner cavity of the limiting sleeve 13 can be achieved, the side wall of the limiting sleeve 13 is equidistantly provided with a plurality of through grooves 14 along the circumferential direction, and the inner wall of the limiting sleeve 13 is provided with a plurality of card balls 15, and the outer wall where the hook 2 is inserted into the inner cavity of the limiting sleeve 13 is provided with a plurality of card grooves 17, and the card ball 15 is embedded in the inner cavity of the card groove 17, and the outer wall of the threaded seat 12 is threadedly sleeved with a threaded sleeve 16;

[0026] Since the limiting sleeve 13 is naturally set to expand outward from bottom to top, when the threaded sleeve 16 moves upward along the outer wall of the threaded seat 12, the top end of the limiting sleeve 13 is gradually contracted, thereby causing the card ball 15 installed on the inner wall of the limiting sleeve 13 to gradually embed into the inner cavity of the card slot 17, so as to realize the positioning of the hook 2 in the inner cavity of the limiting sleeve 13. Conversely, when the threaded sleeve 16 moving downward is separated from the limiting sleeve 13, the limiting sleeve 13 expands outward under the action of its own elastic force, so that the card ball 15 is separated from the inner cavity of the card slot 17, thereby realizing the removal of the hook 2 in the inner cavity of the limiting sleeve 13.

[0027] The working principle of an insulating double-headed hook rod in this embodiment is as follows:

[0028] During the live connection process of the distribution network, the hooks 2 respectively arranged at the upper and lower ends of the insulating rod body 1 are respectively sleeved on the outer walls of the overhead line and the lead wire, so that the two form a preliminary stable connection relationship; the hook 2 is pushed by external force to cause the connecting piece 11, the moving rod 9, and the hemisphere 10 to move toward the rotating seat 7 until the hemisphere 10 is separated from the inner cavity of the positioning groove 6 in the vertical direction. At this time, the spring 8 is forced to compress, and the external force rotates the hook 2 to cause it to rotate 90 degrees clockwise or counterclockwise. At this time, the hemisphere 10 rotates to correspond to the position of the positioning groove 6 in the horizontal direction. At this time, the external force on the hook 2 is removed, and the spring 8 The elastic force of the movable rod 9 and the hemisphere 10 is used to move away from the rotating seat 7 until the hemisphere 10 is embedded in the inner cavity of the positioning groove 6 at the corresponding horizontal position, so as to realize the positioning of the hemisphere 10 after the rotation adjustment. At this time, the movable rod 9, the connecting piece 11 and the hook 2 connected to the hemisphere 10 are limited after the rotation; when the upper and lower hooks 2 are rotated to be perpendicular to the right side of the insulating rod body 1, the device is in a "C" shape as a whole; when the upper and lower hooks 2 are rotated to the left and right sides of the insulating rod body 1 respectively, the device is in a "Z" shape as a whole, so as to provide positioning support between the overhead lines and the lead wires that are displaced up and down;

[0029] When the hook 2 needs to be disassembled for maintenance, the threaded sleeve 16 is rotated by external force to cause it to move downward along the outer wall of the threaded seat 12. At this time, the limiting sleeve 13 is separated from the limiting effect of the threaded sleeve 16. Since the inner cavity of the limiting sleeve 13 in a natural state is in an outward expansion and extension state from bottom to top, the limiting sleeve 13 without the limiting effect of the threaded sleeve 16 expands outward under its own elastic force, causing the card ball 15 on the inner wall of the limiting sleeve 13 to separate from the inner cavity of the card slot 17. At this time, the hook 2 loses its limiting effect in the inner cavity of the limiting sleeve 13, thereby enabling the hook 2 to be disassembled at the limiting sleeve 13;

[0030] The utility model can form a stable connection relationship between the overhead line and the lead wire, realize stable support between the two, avoid the safety hazard caused by the lead wire falling off during the connection process, causing phase short circuit or grounding fault, in addition, the positioned lead wire can enter the space between the hook 2 and the baffle 18, avoid the situation that the lead wire stays at the intersection of the two baffles 18 and is separated from the inner cavity of the hook 2 when subjected to external force, and the fixation of the lead wire is safer and more reliable, and the insulating rod body 1 and the two hooks 2 can flexibly form a "C" type or "Z" type structure, and thus can be adapted to the positioning support between the overhead line and the lead wire that are staggered up and down. In addition, the hook 2 can be separately disassembled and replaced or maintained regularly without replacing the equipment body, which is more cost-effective.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
