[0023] By installing the heat dissipation structure in the installation frame 2 communicated with the protection shell 1, and driving the threaded rod 6 to rotate by the pulley 4, the threaded rod 6 controls the baffle 7 to move, so that the baffle 7 controls the communication and closure of the no. Heat -radiating net frame 21 and protection shell 1 can be used according to different environments, to avoid the internal moisture caused by the excessive moisture outside in the rainy weather.

[0024] By adopting the above technical scheme, the transmission belt 5 is installed on the pulley 4, and the micro motor 8 is fixedly connected to the one side of the pulley 4 away from the installation frame 2, for driving the two pulleys 4 to rotate, so that the pulley 4 drives the threaded rod 6 to rotate.

[0025] By adopting the above technical scheme, the baffle 7 is fixedly connected with the fixed frame 10 on the front and rear portions, the cleaning brush 11 is slidingly connected in the fixed frame 10, the cleaning brush 11 is fixedly connected with the elastic sheet 12 close to the one side of the fixed frame 10, and the elastic sheet 12 is fixedly connected with the fixed frame 10 on the one side, and the elastic sheet 12 is arranged to drive the cleaning brush 11 to contact with the no. Heat -radiating net frame 21, so that the dust on the no. Heat -radiating net frame 21 can be cleaned.

[0026] By adopting the above technical scheme, in order to facilitate the disassembly of the cover plate 3, the no. Heat -radiating net frame 21 and the heat -radiating net frame 22 are replaced, the insertion rod 23 is fixedly connected to the installation frame 2 on the front and rear portions and close to the one side of the cover plate 3, the insertion rod 23 is inserted into the insertion frame 31, the insertion frame 31 is fixedly connected with the side wall of the cover plate 3 on the one side away from the cover plate 3, the limiting rod 33 is slidingly connected to the insertion frame 31 away from the cover plate 3, the limiting rod 33 is inserted into the insertion rod 23 through the insertion frame 31, the limiting rod 33 is fixedly connected with the tension spring 32 on the one side, and the tension spring 32 is fixedly connected with the insertion frame 31 on the one side.

[0027] The limiting rod 33 can be pulled to separate the limiting rod 33 from the insertion rod 23, and the tension spring 32 is elongated, and then the cover plate 3 is moved to separate the insertion rod 23 from the insertion frame 31.

[0028] The implementation principle of the outer protection structure of the rubidium clock circuit is as follows: in the initial state, the baffle 7 is located close to the cover plate 3, so that the first heat dissipation net frame 21 and the second heat dissipation net frame 22 are in communication with the protective shell 1, so that the heat in the protective shell 1 is dissipated through the first heat dissipation net frame 21 and the second heat dissipation net frame 22; when the outside environment is relatively humid due to rainy weather, the micro motor 8 can be started, so that the micro motor 8 drives the belt pulley to rotate; since the two belt pulleys 4 are provided with the transmission belt 5, the two belt pulleys 4 will rotate simultaneously and drive the threaded rod 6 to rotate, and the threaded rod 6 drives the baffle 7 to move, so that the baffle 7 moves to the side close to the protective shell 1 and is in contact with the fixed plate 9, so that the baffle 7 and the fixed plate 9 form a closed plate, which prevents the first heat dissipation net frame 21 and the second heat dissipation net frame 22 from being disconnected from the protective shell 1, thereby avoiding that the outside water vapor enters the protective shell 1 through the first heat dissipation net frame 21 and the second heat dissipation net frame 22.

[0029] When part of the dust blocks the mesh of the first heat dissipation net frame 21 after long-term use, the threaded rod 6 can be used to drive the baffle 7 to move back and forth, so that the baffle 7 drives the two side cleaning brushes 11 to continuously clean the first heat dissipation net frame 21, thereby ensuring the use of the first heat dissipation net frame 21.
