The invention discloses a vacuum and explosion-proof integrated mechanism. The vacuum and explosion-proof integrated mechanism comprises a mechanism mounting base. A vacuum generator is arranged abovethe mechanism mounting base. The lower portion of the vacuum generator is connected with a gas pipeline. Both ends of the mechanism mounting base are open, and a cavity is formed in the middle of themechanism mounting base. An upper end cover of the mechanism mounting base is provided with an explosion-proof trigger block which can be pushed open. The gas pipeline penetrates through the explosion-proof trigger block and is connected with the cavity. According to the vacuum and explosion-proof integrated mechanism, the explosion-proof trigger block is arranged on the mechanism mounting base so that the explosion-proof trigger block can be pushed open by gas in the cavity when the pressure in the cavity is higher than the atmospheric pressure by a certain value, and thus the gas in the cavity is exhausted; the explosion-proof trigger block and the vacuum generator are combined, so that the structure is simplified; and the gas pressure directly acts on the explosion-proof trigger block,so that the sensitivity of the explosion-proof trigger block to atmospheric pressure changes is improved. The vacuum and explosion-proof integrated mechanism is applied to the field of automobile maintenance equipment.
