Abstract

The invention provides an outdoor roll screen fixing device based on electromagnet gravitation. The outdoor roll screen fixing device comprises a box body, electromagnet cores, fixed screws, a connecting wire, a box cover, electromagnet coils and a roll screen on the ground. The box body is placed underground, the electromagnet cores are fixed to the bottom of the box body through the fixed screws, the electromagnet coils are wound around the electromagnet cores, the electromagnet coils are connected through the connecting wire, the connecting wire is connected with a power source, the box cover is placed on the box body, and the roll screen on the ground is placed on the box cover. The box body is placed underground, no space is occupied, the box cover is placed on the ground surface, the connecting wire is connected with the power source to power on the electromagnet coils, electromagnets start to work, the roll screen on the ground is fixed to the box cover through gravitation of the electromagnets on iron, even in outdoor gale weather, the roll screen can be kept stable and free of falling, after exhibition is finished, the connecting wire is disconnected from the power source, magnetism of the electromagnets disappears, the gravitation on the roll screen also disappears, the roll screen on the ground can be collected, and convenience and rapidness are achieved.

Description

technical field [0001] The invention relates to a roll-up banner fixing device, in particular to an outdoor roll-up banner fixing device based on electromagnet attraction. Background technique [0002] As a portable display device, roll-up banners are widely used in major exhibitions and are one of the important means of advertising. During the display process, roll-up banners need to be fixed on the ground, especially when displayed outdoors. The roll-up is very easy to fall over. The traditional fixation method is to tie the roll-up with a rope, or press the bottom of the roll-up with a heavy object. The fixing effect is not good, and repeated inspections are required, which is time-consuming and labor-intensive. Contents of the invention [0003] In order to solve the current situation that roll-up banners are not easy to fix in the prior art, the present invention provides an outdoor roll-up banner fixing device based on electromagnet attraction. [0004] The outdoor ...
