Problems solved by technology

At present, the matching thresholds are generally fixed thresholds or lifting thresholds, but there are many defects in fixed thresholds, such as fixed thresholds are not conducive to the entry and exit of vehicles, personnel and materials at the mouth. Therefore, in general, in order to improve the usual use effect and convenience, More use of lifting threshold
At present, the commonly used lifting threshold in civil air defense projects is the hydraulic lifting threshold, but the hydraulic lifting threshold has the disadvantages of large space required for the lifting mechanism, high price, and hidden dangers of leakage.

Abstract

The invention discloses a manual and electric dual-purpose annular lifting threshold. The manual and electric dual-purpose annular lifting threshold is used in cooperation with a closed protective door and comprises a base and a lifting threshold body, the base is fixed to the bottom face, a lifting groove and a containing groove are formed in the base, the lifting threshold body is arranged in the lifting groove, the top face of the lifting threshold body is flush with the top face of the base, and an internal mechanism is arranged on the base; and the internal mechanism comprises a lifting mechanism, a guide mechanism and a stroke control device, the lifting mechanism comprises an electric device, a manual device and a lifting device, and the electric device and the manual device are both connected with the lifting device. The manual and electric dual-purpose annular lifting threshold has a manual control mode and an electric control mode, control is flexible, reliability is high, the lifting threshold body is arranged to be in an arc shape and matched with the closed protective door, impact loads transmitted by the closed protective door are evenly borne, the resistance of the lifting threshold body is improved, and then the structural stability of the closed protective door is guaranteed.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a ring-shaped lifting threshold for both flashlight and electric power. Background technique [0002] The entrances and exits of civil air defense equipment are equipped with airtight protective doors. Generally, the airtight protective doors are equipped with thresholds. When the door leaf is subjected to shock wave loads in wartime, the threshold and the door frame can block the impact together with the door leaf. And the threshold And the door frame can also support the door leaf to a certain extent to avoid large deformation of the door leaf. At present, the matching thresholds are generally fixed thresholds or lifting thresholds, but there are many defects in fixed thresholds, such as fixed thresholds are not conducive to the entry and exit of vehicles, personnel and materials at the mouth. Therefore, in general, in order to improve the usual use effect...
