Base anti-toppling device for movable planning fence

Abstract

The invention relates to the technical field of planning fence fixing, and discloses a base anti-toppling device for a movable planning fence, which comprises a base, an inserting rod is clamped in the middle of the base, a clamping groove is formed in the middle of the inserting rod, an electromagnet is fixedly connected to the middle of the base, a piezoresistor is fixedly connected to the inner wall of the middle of the base, and a positive plate is fixedly connected to the inner wall of the base. According to the base anti-toppling device for a movable planning fence, an inserting rod drives a pressing block to move, the pressing block drives a concave ball to move, and then an air bag and a dielectric plate are used in cooperation, so that the effect of controlling on-off of an electromagnet is achieved, the pressing block moves towards the left under the action force, at the moment, the arc groove in the middle of the concave ball drives the trigger rod to move along the inner wall of the arc groove; and the trigger rod extrudes the air bag, the air bag expands and deforms, the air bag expands leftwards all the time to drive the dielectric plate to move leftwards, the voltage at the two ends of the positive plate and the negative plate is decreased, the working voltage of the piezoresistor is achieved, and the electromagnet is powered on to generate a magnetic field.

Description

technical field [0001] The invention relates to the technical field of fixing a planning column, in particular to a base anti-dumping device for an activity planning column. Background technique [0002] Event planning is an effective behavior to increase market share. An executable, operable, and creative event planning proposal can effectively enhance the company's popularity and brand reputation. In order to increase the awareness of the general public, it is usually necessary to use Different media are used for publicity, and only in this way can the audience effectively understand the cultural connotation of a brand. In order to improve the effect of the demonstration, it is usually necessary to use the planning column for display. [0003] Most of the existing planning columns are placed in shopping malls or outdoors. Because they will be affected by external wind and human pull when placed outside, they are prone to dumping. However, the existing planning columns have...
