AI Technical Summary
Technical Problem
After the blasting door is in place, it is prone to rebound due to inertia and pressure fluctuations, which affects its working performance and sealing effect, and shortens its service life.
Method used
The system employs an anti-rebound mechanism, which includes a base, housing, locking arm, reset mechanism, and unlocking mechanism. A reset spring provides elastic reset force to the locking arm, and an electromagnet drives the locking arm to unlock, ensuring stable opening of the blasting door.
Benefits of technology
It effectively prevents the door from rebounding after a blast, ensuring sealing performance and service life. It can be quickly unlocked for easy reoperation and is suitable for harsh working conditions.

Abstract
The invention discloses an anti-springback mechanism for opening an explosion door. The anti-springback mechanism comprises a base, a shell, a locking rotating arm, a reset mechanism, an unlocking mechanism and a check block. The shell is fixedly mounted on the base; the locking rotating arm is rotationally mounted on the shell through a rotating shaft; the reset mechanism is arranged between the shell and the locking rotating arm and used for providing elastic reset force for the locking rotating arm, wherein the elastic reset force enables the locking rotating arm to tend to rotate towards the locking position. The unlocking mechanism comprises an electromagnet and a connector, the electromagnet is fixedly installed on the base, one end of the connector is fixedly connected to the locking rotating arm, and the other end of the connector is in driving connection with an iron core of the electromagnet; and the stop block is fixedly connected to the explosion door. Wherein the locking rotating arm is provided with a locking position which is embedded with the check block under the driving of the reset mechanism so as to prevent the explosion door from rebounding, and an unlocking position which is separated from the check block by overcoming the reset force of the reset mechanism under the driving of the electromagnet. Reliable locking and quick unlocking can be achieved, the structure is simple and durable, and installation and maintenance are convenient.
