[0022] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0023] See also Figure 1 - Figure 4 , a universal insulating scaffold connection device of the present embodiment includes an insulating rod 1 and a fixed cylinder 2, the fixed cylinder 2 is plug-in connected to the inside of the insulating rod 1, the bottom of the fixed cylinder 2 is fixedly connected to two connecting blocks 3, the bottom of the connecting block 3 is fixedly connected to a movable block 4, the bottom of the insulating rod 1 is processed with a notch 5, the movable block 4 is plug-in connected to the inside of the notch 5, the bottom side of the notch 5 is processed with a movable groove 7, the movable block 4 is movably connected to the inside of the movable groove 7, the top side of the notch 5 is processed with a connecting groove 6, the connecting block 3 is movably connected to the inside of the connecting groove 6, one side of the movable groove 7 is processed with a groove 9, the inside of the groove 9 is movably connected with a lock tongue 8, one end of the lock tongue 8 is movably connected to the inside of the movable groove 7, the notch 5, the connecting groove 6 and the movable groove 7 are connected to each other, and the shape of the connecting groove 6 and the movable groove 7 is an arc groove;

[0024] When the insulating scaffolding needs to be assembled, multiple fixing cylinders 2 are fixed through the insulating rod 1 in sequence. When the fixing cylinder 2 is inserted into the interior of the insulating rod 1, the fixing cylinder 2 will drive the connecting block 3 to move, and the connecting block 3 will drive the movable block 4 to move inside the insulating rod 1, so that the movable block 4 is located directly above the notch 5. When the fixing cylinder 2 reaches the bottom end of the interior of the insulating rod 1, the movable block 4 will enter the interior of the notch 5.

[0025] Secondly, rotate the fixed cylinder 2 so that the fixed cylinder 2 drives the connecting block 3 and the movable block 4 to rotate. The connecting block 3 will rotate along the inside of the connecting groove 6, and the movable block 4 will rotate along the inside of the movable groove 7. When the movable block 4 contacts the lock tongue 8, the movable block 4 will squeeze the lock tongue 8 so that the lock tongue 8 enters the inside of the groove 9. When the lock tongue 8 completely enters the inside of the groove 9, the movable block 4 will continue to move along the inside of the movable groove 7. When the movable block 4 loses contact with the lock tongue 8, the lock tongue 8 will reset to limit and fix the movable block 4.

[0026] Furthermore, the inner part of the groove 9 is movably connected to a limit block 13, and one side of the limit block 13 is fixedly connected to one end of the lock tongue 8. When the lock tongue 8 moves toward the inner part of the groove 9, the lock tongue 8 will drive the limit block 13 to move along the inner part of the groove 9. By providing the limit block 13, the lock tongue 8 can be prevented from being separated from the inner part of the groove 9.

[0027] Furthermore, a connecting rod 11 is fixedly connected to one side of the limit block 13, and the connecting rod 11 passes through the side wall of the insulating rod 1. One end of the connecting rod 11 is fixedly connected to a pull ring 10, and the pull ring 10 is located outside the insulating rod 1.

[0028] Among them, when it is necessary to disassemble the fixed cylinder 2, the pull ring 10 is pulled outward, the pull ring 10 will drive the connecting rod 11 to move outward, the connecting rod 11 will drive the limit block 13 to move, and the limit block 13 will drive the lock tongue 8 to move toward the inside of the groove 9. When the lock tongue 8 completely enters the inside of the groove 9, the fixed cylinder 2 is rotated, and the fixed cylinder 2 will drive the connecting block 3 and the movable block 4 to rotate. The movable block 4 will rotate along the inside of the movable groove 7 to the notch 5, and the fixed cylinder 2 is pulled outward, thereby separating the fixed cylinder 2 from the insulating rod 1, facilitating the rapid disassembly of the insulating scaffolding;

[0029] Furthermore, a return spring 12 is provided on the outside of the connecting rod 11, one end of the return spring 12 is fixedly connected to one side of the limit block 13, and the other end of the return spring 12 is fixedly connected to one side of the inner wall of the groove 9. By providing the return spring 12, when the pull ring 10 is pulled, the connecting rod 11 will drive the return spring 12 to compress, and when the pull ring 10 is released, the return spring 12 is reset and extended, and the return spring 12 will drive the limit block 13 and the lock tongue 8 to move, thereby resetting one end of the lock tongue 8;

[0030] Furthermore, two guide blocks 14 are fixedly connected to both sides of the bottom of the fixed cylinder 2, and two guide grooves 15 are processed on both sides of the inner wall of the insulating rod 1, and the guide blocks 14 are movably connected to the inside of the guide grooves 15;

[0031] When installing the fixed cylinder 2, since the movable block 4 needs to be inserted into the interior of the notch 5, when the fixed cylinder 2 is inserted into the interior of the insulating rod 1, the fixed cylinder 2 will block the view of the interior of the insulating rod 1, making it inconvenient to align the movable block 4 with the interior of the notch 5. When the guide block 14 is inserted into the interior of the guide groove 15, the movable block 4 will be located directly above the notch 5. When the guide block 14 passes through the guide groove 15 and completely enters the interior of the rotating groove 16, the movable block 4 will be located at the bottom of the notch 5, thereby facilitating the movable block 4 to enter the interior of the notch 5, thereby making the connection between the insulating rod 1 and the fixed cylinder 2 simpler and faster;

[0032] Furthermore, a rotation groove 16 is processed at the bottom of the guide groove 15, and the guide block 14 is movably connected to the inside of the rotation groove 16. When the guide block 14 passes through the guide groove 15 and completely enters the inside of the rotation groove 16, it turns to the fixed cylinder 2. The fixed cylinder 2 will drive the movable block 4 to rotate along the inside of the movable groove 7. At the same time, the fixed cylinder 2 will drive the guide block 14 to rotate along the inside of the rotation groove 16.

[0033] Working principle: When the fixed cylinder 2 is inserted into the interior of the insulating rod 1, the fixed cylinder 2 will drive the connecting block 3 and the movable block 4 to move, so that the movable block 4 is located directly above the notch 5. When the fixed cylinder 2 reaches the inner bottom end of the insulating rod 1, the movable block 4 will enter the interior of the notch 5, and then the fixed cylinder 2 is rotated so that the fixed cylinder 2 drives the connecting block 3 and the movable block 4 to rotate, and the movable block 4 will rotate along the inside of the movable groove 7. When the movable block 4 contacts the lock tongue 8, the movable block 4 will squeeze the lock tongue 8. When the lock tongue 8 completely enters the inside of the groove 9, the movable block 4 will continue to move along the inside of the movable groove 7. When the movable block 4 is out of contact with the lock tongue 8, the reset spring 12 extends and pushes the lock tongue 8 to limit and fix the movable block 4. The operation is simple and convenient.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
