[0022] Example 1, please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0023] An openable observation window comprises a ring network cabinet door 1 with an observation port, wherein the ring network cabinet door 1 is fixedly connected to a hinge seat 2 on the front side near the left side thereof, a valve 3 is rotatably connected inside the hinge seat 2, an explosion-proof perspective glass 4 is fixedly connected inside the valve 3, a fitting positioning frame 5 is fixedly connected to the front side near the right side of the ring network cabinet door 1, a connecting card slot 6 is provided on the surface near the middle of the fitting positioning frame 5, a connecting card plate 7 is fixedly connected to the right side of the valve 3, the surface of the connecting card plate 7 is snap-fitted and adapted to the inner wall of the connecting card slot 6, and the connecting card plate The interior of 7 and the interior of the connecting slot 6 are both threadedly connected with a locking bolt 8 through an internal thread groove. An adjustment slot is provided inside the fitting positioning frame 5. The inner wall of the adjustment slot is slidably connected to a sliding rod 9. One end of the sliding rod 9 is fixedly connected to an anti-slip card plate 10. An anti-slip slot 11 is provided on the right side of the valve 3. The inner wall of the anti-slip slot 11 and the surface of the anti-slip card plate 10 are snapped and adapted. A compression spring 12 is connected between the side of the sliding rod 9 and the surface of the inner wall of the adjustment slot through a damping pad. The right side of the sliding rod 9 is fixedly connected to an externally leaking insulating rod 13.

[0024] Specifically, such as Figure 1-Figure 5 As shown, a protruding pull plate 14 is fixedly connected to the front side of the valve 3. The entire component material of the protruding pull plate 14 is insulating rubber. The protruding pull plate 14 can be used to open the unlocked valve 3 by insulating.

[0025] Specifically, such as Figure 1-Figure 5 As shown, a balancing plate 18 is fixedly connected to the side of the sliding rod 9, and a balancing groove 19 is formed on the side of the inner wall of the adjustment groove. The inner wall of the balancing groove 19 is in sliding connection with the surface of the balancing plate 18. The arrangement of the balancing plates 18 and 19 ensures smooth movement of the sliding rod 9 in the adjustment groove. A guide wheel 20 is rotatably connected to the surface of the inner wall of the adjustment groove via a pin. The surface of the guide wheel 20 is in rolling connection with the surface of the sliding rod 9. The guide wheel 20 in the adjustment groove can provide a guiding and power-assisted guidance effect.

[0026] Furthermore, one end of the exposed insulating rod 13 is fixedly connected to a connecting rod 21 , the surface of which is coated with a wear-resistant coating. The addition of the connecting rod 21 allows the upper and lower exposed insulating rods 13 to be connected into a whole.

[0027] Example 2, please refer to Figure 1-Figure 5The difference between this embodiment and embodiment 1 is that a magnetic positioning plate 15 is fixedly connected to the front side of the fitting and positioning frame 5, and a magnetic positioning plate 2 16 is fixedly connected to the rear side of the valve 3. The surface of the magnetic positioning plate 2 16 and the surface of the magnetic positioning plate 1 15 are magnetically abutted. Under the action of the magnetic positioning plates 15 and 16, the fitting and locking effect of the valve 3 on the fitting and positioning frame 5 can be enhanced. The bottom of the valve 3 and the bottom of the fitting and positioning frame 5 are both fixedly connected to a padlock plate 17 with a padlock hole. The padlock holes on the two padlock plates 17 abut and communicate with each other, and can be padlocked through the padlock hole in the lower padlock plate 17.

[0028] The working principle of the present invention is as follows: when in use, a valve 3 is provided on the ring network cabinet door 1, which can be used to open and close the leakage observation port, and the internal observation can be carried out through the explosion-proof perspective glass 4 on the valve 3, so that the valve 3 can be swung open and closed under the guidance and control of the hinge seat 2 on the ring network cabinet door 1. Under normal circumstances, the locking structure on the fitting positioning frame 5 can restrain the valve 3. Under the action of the magnetic positioning plate 1 15 and the magnetic positioning plate 2 16, the fitting locking effect of the valve 3 on the fitting positioning frame 5 can be enhanced. When the valve 3 needs to be unlocked and opened, the locking bolt can be rotated externally away from the internal thread groove in the connecting card plate 7 and the connecting card slot 6 to perform the basic screwing of the valve 3 on the fitting positioning frame 5. In the locked state, pulling the connecting rod 21 from the outside can drive the leakage insulating rod 13 to move, and the movement of the leakage insulating rod 13 can drive the sliding screw to move in the adjustment slot. The guide wheel 20 in the adjustment slot can play a guiding role, and pull the anti-slip card plate 10 away from the anti-slip card slot 11. The damping pad on the compression spring 12 is used for buffering, and the elastic contraction and tightening of the sliding rod 9 of the compression spring 12 can be completed. Then the external force pulls the raised pulling plate 14 to pull the valve 3 open. If the locking and reinforcement effect of the valve 3 is required, it can be padlocked through the padlock hole in the padlock plate 17 below to ensure the convenient opening and closing of the observation window on the ring network cabinet door 1 and the observation effect.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
