Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
First consult shown in Fig. 1 ~ 4, once threshold 12, locking system 13 and a mechanical arm mechanism 14 are formed primarily of threshold 11 on for the activity threshold 10 of a kind of closed guard gate of the present utility model, lower threshold 12 is embedded in the ground 21 of latched position in advance, rubber tile and base plate is laid at ordinary times on lower threshold 12,11, upper threshold is positioned on the threshold support 22 beyond passage ground, not affect normal pass.Mechanical arm mechanism 14 is installed on closed guard gate 15, when there are disaster or chaos caused by war, closed guard gate 15 closes, rubber tile on lower threshold 12 and base plate are removed, upper threshold 11 is mounted on the mechanical arm mechanism 14 of closed guard gate 15, fix with bolt, and by mechanical arm mechanism 14, upper threshold 11 is moved on lower threshold 12, position with lower threshold 12.Coordinate shown in Fig. 4, locking system 13 is also installed on closed guard gate 15, in the bottom correspondence of locking system 13, the top of threshold 11 is provided with flexible tapered end 131, corresponding flexible tapered end 131 offers the first lockhole 110 and the second lockhole 120 respectively respectively on upper threshold 11 and lower threshold 12, when sealed, flexible tapered end 131 is inserted in the first lockhole 110 and the second lockhole 120 downwards successively, carry out sealed to upper threshold 11, lower threshold 12 and closed guard gate 15, upper threshold 11 is fixed between lower threshold 11 and the closed guard gate 15 after closing, carries out protection when disaster or chaos caused by war.
Shown in composition graphs 5 and Fig. 6, upper threshold 111 is the rectangular box beam structure of an inner hollow, upper threshold 11 comprises L shape top board 111 and the L shape base plate 112 be welded to each other, the top board 111 be welded to each other and the sidepiece of base plate 112 are welded with one first plate body 161 and one second plate body 162, after the installation of upper threshold 11, first plate body 161 and the second plate body 162 are connected between upper threshold 11 and closed guard gate 15 as sealing plate, closed guard gate 15 is provided with one the 3rd plate body 163, 3rd plate body 163 is inserted between the first plate body 161 and the second plate body 162, and at the first plate body 161, the upper hermetically-sealed construction between threshold 11 and closed guard gate 15 of weather strip 164 formation is filled with between second plate body 162 and the 3rd plate body 163, strengthen the sealing performance between activity threshold 10 and closed guard gate 15, carry out antiseep shutoff.And in order to strengthen antiseep effect, the middle part of the second plate body 162 is turned down formation one sealing surface 1621 downwards, and sealing surface 1621 fits in Flood gate 14.Structure is simple, easy accessibility, good seal performance.Top board 111 and base plate 112 are offered the first lockhole 110 respectively, for the locking coordinating the flexible tapered end 131 of locking system 13 to carry out upper threshold 111 and closed guard gate 15.
