When actually used, when passing through a narrow area, the explosion-proof shield can be folded and stored by flipping, which reduces the overall volume of the explosion-proof shield, effectively improves the convenience of passage of the explosion-proof shield, and is conducive to the movement and carrying of the explosion-proof shield. In addition, a plug-in locking structure is adopted for the shield bodies on both sides. After the unfolding arrangement of the shield body is completed, the locking plug post 10 can be inserted into the connection between the shield bodies on both sides by shifting the switching block 9, and the unfolded upper shield body 1 and the lower shield body 2 are locked and limited by the plug-in limit. The switching is convenient and fast, and the unfolding assembly of the shield body can be completed in a short time, which greatly improves the convenience of use of the explosion-proof shield.
