Problems solved by technology

[0002] At present, the storage curtains used in extracurricular teaching are usually soft curtains because of their convenient storage. However, their softness and good storage characteristics bring about uncontrolled unfolding disadvantages. In practical applications, wind blowing will cause ripples and shakes to them Therefore, a kind of extracurricular education teaching screen display device that can weaken this uncontrolled influence is proposed here

Abstract

The invention discloses a storage type screen display device for extracurricular education, and belongs to the field of screen display. The storage type screen display device comprises a storage shell, a curtain, a power device, a transmission assembly and an air-entrapping structure; a cloth outlet communicated with the outside is formed in the lower end of the storage shell; the two side edges of the curtain are fixedly connected with supporting and pulling soft columns, the bottom edge is fixedly connected with a gravity guiding hollow rod, and the top edge is fixedly connected with a main rolling shaft. The power device is in power connection with the main winding shaft or the gas filling structure through the transmission assembly; a one-way air inlet valve and a one-way air outlet valve are arranged at the two ends of the airflow channel respectively. The two sides of the curtain can be inflated into air rods, it is prevented that watching and learning are affected by over-soft folding or shaking, the curtain can be stored and deflated at the same time after being finished, the blackboard is cleaned through extrusion force, control over the stability of the soft curtain is greatly improved, the watching effect is better, and teaching is better facilitated.

Description

technical field [0001] The invention relates to the field of educational storage screens, and more particularly, to a storage-type screen display device for extracurricular education. Background technique [0002] At present, the storage curtains used in extracurricular teaching are usually made of soft curtains due to their convenient storage. However, their soft and good storage characteristics bring uncontrolled deployment drawbacks. In practical applications, wind blowing will cause ripples and shaking. Therefore, a screen display device for extracurricular education and teaching that can weaken the uncontrolled influence is proposed here. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a storage-type screen display device for extracurricular education, which has high controllability, is more conducive to unfolding and viewing, and does not affect the convenience of storage. [000...
