Embodiment 1

[0048] An outdoor ideological and political display device, comprising a base, a groove 23 arranged on the base, a display mechanism 33 arranged in the groove 23, and a display mechanism 33 arranged on the groove 23 Between and for the telescopic mechanism that the display mechanism 33 lifts in the groove 23, and the drainage mechanism arranged on the wall of the groove 23;

[0049] The display mechanism includes a display frame matched with the groove, a display board 332 arranged on the display frame, a display surface 331 arranged on the display board 332, a cover 1 is arranged on the upper part of the display frame, The lower part of the display frame is provided with a sealing plate 10, and a through hole is arranged in the middle of the sealing plate 10, and a sealing cylinder 8 is arranged in the through hole;

[0050] The telescopic mechanism includes a telescopic guide module and a telescopic module arranged in the sealing cylinder and matched with the bottom of the g...

Embodiment 2

[0066] The difference between it and the first embodiment is that: the front end of the air duct 11 is provided with a louver 112 .

[0067] In this embodiment, louvers are arranged at the front end of the air duct, and the louvers can be opened by the negative pressure generated by the fan when the fan is turned on, but will not be opened when no negative pressure is generated. Cleanliness, dust-proof sponge can be installed at the opening. This design structure can effectively prevent small animals and precipitation or sand or snow falling into it under strong convective weather, ensuring the stability of the device.

Embodiment 3

[0069] The difference between it and Embodiment 1 or 2 is that an emergency protection mechanism is provided at the groove 23, and the emergency protection mechanism includes a buckle 19 disposed at the bottom of the groove 23, and a buckle 19 disposed on the sealing plate 10. The bayonet pin 12, and the pressure relief module arranged on the sealing plate 10.

[0070] The bayonet 12 is a boss provided at the bottom for locking; the buckle includes a bayonet 195, a pin hole arranged on the side wall of the bay 195, and a spring 193 arranged on the pin hole. The locking pin 192 is provided with an electromagnet 194 at the rear end of the locking pin 192 , and a waterproof casing is provided on the surface of the electromagnet 194 ; an elastic buffer layer 191 is provided at the bottom of the slot 195 .

[0071] The pressure relief module includes a pressure relief hole arranged on the sealing plate 10, and the pressure relief hole communicates with the exhaust hole provided on ...

Abstract

The invention provides an outdoor display device of ideologies and politics. The device comprises a base, a groove formed in the base, a display mechanism arranged in the groove, a retracting mechanism arranged between the display mechanism and the groove for lifting the displaying mechanism in the groove, and a water drainage mechanism arranged at the periphery wall of the groove. According to the outdoor display device of ideologies and politics, the lifting mode is used for administering self-protection measures during the occurrence of severe convection weather to retract the device into the groove to lower the height. At the same time, a sealed display structure is used for preventing the phenomenon that stagnant water enters the display mechanism, and combined with the inclined ring groove and the ring water seal, the display mechanism can not only retract freely in the groove, but also achieve the automatic water drainage. An emergency protection mechanism is used for implementing further self-protection during the occurrence of severe convection weather to guarantee that the device can achieve intelligent and automatic control after being inducted for once, the personnel maintenance is reduced, and reconstruction investment for the damages caused by the severe convection weather can be lowered.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to an outdoor ideological and political display device. Background technique [0002] Traditional ideological and political education is usually based on teachers' classroom lectures, rote memorization and exercise training, which can easily make students lose motivation and interest in learning ideological and political theory courses. At the same time, many schools use large class teaching, and teachers often lack the ability to explain exercises Pertinence, coupled with limited teaching time, many students do not understand or do not understand the basic theoretical knowledge taught by the teacher in the classroom, and there are few other ways to get in touch with ideological and political teaching in daily life, and the interest is poor. It makes it difficult for students to be interested in active learning and research after class, so how to use the limited resource...
