Embodiment Construction

[0042] The present invention will be further described with reference to the accompanying drawings.

[0043] A living threshold type double-leaf civil air defense door structure, refer to figure 1 , including two protective doors 2 installed on the body of wall 1, and door locks 21 for fixing the two protective doors 2 are installed on the protective doors 2.

[0044] refer to image 3 and Figure 4, there is a gap between the two protective doors 2 and the ground 11, and an overturning groove 3 is provided on the ground 11. The length of the overturning groove 3 is greater than the total length of the two protective doors 2. There is a living threshold 32 with an L-shaped cross-section inside. The living threshold 32 includes a sealing plate 321 and an abutting plate 322 vertically fixed on one side of the sealing plate 321. The rotating shaft 33 is connected to the sealing plate 321 and the abutting plate 322 in rotation. Junction. The peripheral wall of the turning groo...

Abstract

The invention discloses a movable threshold type double-leaf civil protection door structure and relates to the field of protection equipment. The structure comprises two protection doors, wherein a turnover groove is formed in the ground, a movable threshold is rotationally connected in the turnover groove, and the movable threshold comprises a sealing plate and an abutting plate perpendicularlyfixed on one side edge of the sealing plate; an accommodating groove is formed on the peripheral wall of the turnover groove, a shifting block is arranged in the accommodating groove, a main pull cordis arranged in the accommodating groove, two ends of the main pull cord are connected to two ends of the shifting block respectively, guide wheels are arranged on two sides of the shifting block, andthe main pull cord winds around the guide wheels and is in a tightened state; a pull assembly for pulling the main pull rope back and forth is arranged on one side of the shifting block; when the pull assembly pulls the main pull cord and drives the shifting block to move, the shifting block turns over the movable threshold and allows the sealing plate to abut against one side of each protectiondoor and the wall of the turnover groove, and then, the shifting block is supported on the lower side of the abutting plate. The threshold state is switched through turnover of the movable threshold,so that the movable threshold is more convenient to mount and dismount.

Description

technical field [0001] The invention relates to the field of protective equipment, in particular to a living threshold-type double-leaf air defense door structure. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, and a variety of civil air defense equipment such as single and double protective airtight doors and airtight doors with living thresholds. [0003] The characteristic of the living threshold is that the threshold is not installed at ordinary times, the ground is flat, which is convenient for personnel and vehicles to pass, and the threshold can be quickly installed in wartime to meet the requirements of protection and airtight functions, and quickly realize the conversion of peacetime and wartime functions. This type of door is applicable...
