[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Referring to the accompanying drawings: This observation window for a high-voltage distribution cabinet that can be quickly assembled includes a window frame 1, and a first perspective window 2 and a second perspective window 3 that slide in the window frame 1 and are staggered in the upper and lower positions. The first perspective window 2 blocks the upper section of the window frame 1, and the second perspective window 3 blocks the lower section of the window frame 1. The window frame 1 includes a main frame body 11 and a secondary frame rod 12. The main frame body 11 has a side opening 11-a for guiding the first perspective window 2 and the second perspective window 3 to enter the main frame body 11. The side opening 11-a allows two short axis sections of the main frame body 11 to form a socket 11-b for the secondary frame rod 12 to enter. The socket 11-b is provided with a positioning socket 11-b1, a first guide channel 11-b2, and a second guide channel 11-b3 respectively connected with the first guide channel 11-b2 and the positioning socket 11-b1 on the short axis section of the main frame body 11, and the sub-frame rod 12 is provided with a positioning rod 4 which reaches the positioning socket 11-b1 through the first guide channel 11-b2 and the second guide channel 11-b3 and is combined with the positioning socket 11-b1, and the short axis section of the main frame body 11 is provided with a locking arm 5 which prevents the positioning rod 4 from escaping from the positioning socket 11-b1 when it reaches the positioning socket 11-b1, and the locking arm 5 is swingable. The principle of the utility model is that the first perspective window 2 and the second perspective window 3 enter into the main frame body 11 through the side opening 11-a, and the inner side surfaces of the main frame body 11 and the sub-frame rod 12 are provided with sliding grooves for realizing the movement of the first perspective window 2 or the second perspective window 3, and the number and position relationship of the sliding grooves match the settings of the two perspective windows. After the installation of the perspective windows is completed, the sub-frame rod 12 enters the socket 11-b set in the short axis section of the main frame body 11, and the socket 11-b and the sub-frame rod 12 are clearance-fitted, so that there is no resistance during fitting, so that the sub-frame body 12 can quickly enter into the socket 11-b, in order to avoid the sub-frame being damaged due to clearance fitting. In order to solve the problem that the rod 12 cannot be stably present in the socket 11-b, the sub-frame rod 12 is stably present in the socket 11-b through the positioning rod 4, the positioning socket 11-b1, and the locking arm 5. That is, the positioning rod 4 synchronously enters the first guide channel 11-b2 when part of the sub-frame rod 12 enters the socket 11-b, and then enters the positioning socket 11-b1 along the trajectory provided by the first guide channel 11-b2 and the second guide channel 11-b3, and then the locking arm 5 is used to prevent the positioning rod 4 from being separated from the positioning socket 11-b1. This method can realize a tool-free and parts-free assembly mode, and also realizes fast and convenient assembly.

[0020] The first guide channel 11-b2 and the second guide channel 11-b3 are arranged vertically, and a turning transition part 11-b4 is arranged at the connection between the two, which enables the positioning rod 4 to smoothly transition from the first guide channel 11-b2 to the second guide channel 11-b3. Such an arrangement extends the length of the guiding path formed by the first guide channel 11-b2 and the second guide channel 11-b3. In this way, even if the positioning rod 4 is separated from the positioning socket 11-b1, it is relatively difficult to escape from the second guide channel 11-b3 to the first guide channel 11-b2, which eventually causes the separation of the secondary frame rod 12 and the main frame body 11. The turning transition part 11-b4 enables the positioning rod 4 to smoothly slide from the first guide channel 11-b2 to the second guide channel 11-b3, and the turning transition part 11-b4 is in an arc-shaped direction, which can be clearly felt by the user when moving, and will play a corresponding prompting role, so that the user can predict that the positioning rod 4 has reached the turning transition part 11-b4, which can avoid user misjudgment.

[0021] The turning transition portion 11-b4 is formed with an arc surface 11-b41 which is completely fitted on a portion of the surface of the positioning rod 4 when the positioning rod 4 reaches the turning transition portion 11-b4, so that the positioning rod 4 is accurately positioned in the turning transition portion 11-b4 to match the accuracy of the positioning rod 4 entering the second guide passage 11-b3.

[0022] The locking arm 5 has two ends, one end is a connecting end and is provided with an axis rod 6 connected to the short axis section of the main frame 11, and the other end is a locking end and is provided with a locking notch 51 combined with the positioning rod 4. The axis rod 6 realizes the swing of the locking arm 5, that is, the part of the axis rod 6 connected to the main frame 11 is a threaded section, and the part rotatably connected to the locking arm 5 is a smooth section. In this way, the axis rod 6 can be stably set on the main frame 11 by utilizing the threaded connection between the two, and can also be axially connected with the locking arm 5, thereby realizing the swing of the locking arm 5. The setting of the locking notch 51 ensures that when the locking arm 5 is combined with the positioning rod 4, the locking arm 5 not only abuts against the positioning rod 4, but also partially wraps the locking rod 4 through the locking notch 51, thereby increasing the matching depth of the two, thereby achieving a good anti-exit effect.

[0023] The positioning rod 4 is provided with a locked notch 41 which is combined with the locking notch 51. Such a configuration further increases the matching depth between the two and also increases the anti-withdrawal effect simultaneously.

[0024] An extended connecting section 7 is provided on the outer side surface of the main frame 11 and the outer side surface of the auxiliary frame rod 12. The extended connecting section 7 is used to set the fastening bolts for installing the window frame 1 on the high-voltage cabinet. The high-voltage distribution cabinet for installing the observation window is composed of a cabinet body and a cabinet door. The cabinet door is provided with a window installation area for placing the window frame therein. The window installation area is provided with a retaining edge for limiting the final assembly position of the window frame in the window installation area. The extended connecting section 7 contacts the retaining edge and is then connected to the retaining edge by fastening bolts. The thickness of the extended connecting section 7 is smaller than the thickness of the main frame 11 or the auxiliary frame rod 12, and the main frame 11 and the auxiliary frame rod 12 are hollow inside, which makes it more complicated to form connecting holes on the two. The configuration of the plate body of the extended connecting section 7 facilitates the forming of connecting holes.

[0025] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
