222, first baffle 213 is bonded with doorframe 1 with second baffle 222.When closed guard gate closes, first baffle 213 and second baffle
222 are bonded with doorframe 1, and the leakproofness between door leaf 2 and doorframe 1 can be improved, to improve the safety of closed guard gate.First
The circumferential direction of door leaf 21 and the second door leaf 22 is respectively and fixedly provided with sealing strip 23, the sealing strip 23 of setting can be improved door leaf 2 and doorframe 1 it
Between leakproofness.
As shown in figure 3, buffer gear 4 includes sleeve 41, T-type plate 42, reset spring 43, limit plate 44, sleeve 41 is fixed
On door leaf 2, T-type plate 42 is slidably connected with sleeve 41, and 43 one end of reset spring and sleeve 41 are fixed, the other end and T-type plate 42
Fixed, limit plate 44 is fixed on the one end of T-type plate 42 far from sleeve 41.When opening closed guard gate, T-type plate 42 is contacted with wall, T-type
Plate 42 is slided into sleeve 41, and reset spring 43 is compressed, the stress that the elastic force direction and wall that reset spring 43 generates are subject to
It is contrary, therefore the stress that wall is subject to can be reduced.Limit plate 44 is fixed on T-type plate 42, it can be sliding to avoid T-type plate 42
It moves to sleeve 41, can not skid off.
As shown in Figure 1,21 upper end of first door leaf and 22 upper end of the second door leaf are respectively and fixedly provided with suspension hook 24, closed guard gate is generally internal
Casting concrete or steel construction, weight is bigger, and in 2 upper end of door leaf, fixed suspension hook 24 is for use when lifting closed guard gate.
The implementation principle of the present embodiment are as follows: when closing closed guard gate, rotation 311 drive shaft 31 of handwheel rotation, 31 band of shaft
Dynamic first bevel gear 32 rotates, and because first bevel gear 32 is engaged with second bevel gear 35, first bevel gear 32 drives the second cone tooth
35 rotation of wheel.The rotation of 35 rotate driving screw rod 34 of second bevel gear, screw rod 34 are threadedly coupled with connecting plate 36, the side of connecting plate 36
Face is bonded with first door leaf 21, and connecting plate 36 will not be rotated together with screw rod 34, and connecting plate 36 can be along the length side of screw rod 34
To sliding, connecting plate 36 drives bolt 37 to be moved to bolt 37 to the direction close to the second door leaf 22 and is inserted into slot 38.It beats
Closed guard gate is opened, rotates handwheel 311 in the opposite direction, connecting plate 36 drives bolt 37 mobile to the direction far from the second door leaf 22
Slot 38 is detached to bolt 37.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
