Retaining mechanism disclosed in Chinese patent for CN207194750U.Door-plate 4 includes rotation section 6 and is integrally disposed upon on rotation section 6
Sticking department 7, the size shape of sticking department 7 matches with doorframe 2, when sticking department 7 and doorframe 2 are clamped, can pass through retaining mechanism 5
Sticking department 7 and doorframe 2 are locked.
Sticking department 7 is entirely fallen in rotation section 6 in the projection on rotation section 6, and rotation section 6 is towards fixed on the face of doorframe 2
Gasket 8 made of soft elastic material are connected with, can be rubber pad, gasket 8 is arranged around sticking department 7 and is in closed loop,
When door-plate 4 is finally closed, 8 end of door plate 4 of gasket and doorframe 2 of elastomeric flexible play buffer function, and work as sticking department 7 and doorframe
When 2 locking, rotation section 6 squeezes gasket 8 towards doorframe 2, can fill the place of out-of-flatness between rotation section 6 and doorframe 2, rises
To good sealing function.
Rotation section 6 is rotatably connected to back-up roller wheel 9 close to the one end on ground, can be two.Back-up roller wheel 9 abuts ground
Face can effectively mitigate the power that door-plate 4 acts on articulated section 3, extend the service life of articulated section 3.The pressure that articulated section 3 is subject to
After power becomes smaller, the frictional force between door-plate 4 and articulated section 3 is had also been smaller, therefore staff pushes door-plate 4 also more light.
Rotation section 6 is fixedly connected with the abutting block 10 of cuboid shape on the face far from sticking department 7, abut block 10 by elastic material
Material is made, and can be rubber block, since the weight of door-plate 4 is larger, is not easy that door-plate 4 is quickly enabled to stop after door-plate 4 rotates,
Being provided with after abutting block 10 can directly impinge upon on wall 1 to avoid rotation section 6, and elastic abutting block 10 has given rotation section 6
The space of buffering plays a protective role to rotation section 6 and wall 1.
Rotation section 6 is provided on the face for abutting block 10 and is also rotatably connected to lantern ring 11, and the position of lantern ring 11 is corresponded on wall 1
It is fixedly connected with limited post 12, after door-plate 4 fully opens, lantern ring 11 can be socketed on limited post 12 by staff, from
And the position of door-plate 4 is limited, it avoids door-plate 4 from voluntarily rotating, generates unsafe condition.Sticking department 7 is far from solid on the face for having lantern ring 11
Surely it is connected with door handle 13, the door handle 13 acts on power on door handle 13 convenient for staff, thus more convenient
Push door-plate 4.
As shown in figure 3, offering internal cavities 14 inside door-plate 4, reinforcing is fixedly connected on the inner wall of internal cavities 14
Reinforcing bar 15.The weight of door-plate 4 can be reduced by offering internal cavities 14, and reinforced steel 15 can ensure the intensity of door-plate 4.It is interior
Portion space vacuumizes setting, and setting in this way improves the soundproof effect of closed guard gate.
As shown in figure 4,4 outer layer of door-plate is fixedly connected with thermal insulation layer 16, thermal insulation layer 16 is made of heat-barrier material, such as asbestos
Plate, thermal insulation layer 16 enable closed guard gate's effective trap heat when fire occurs.16 trypsin method of thermal insulation layer has corrosion-resistant coating 17,
Such as paint, corrosion-resistant coating 17 can protect the surface of closed guard gate, extend the service life of closed guard gate.
In conclusion can effectively mitigate the quality of door-plate 4 by setting internal cavities 14, mitigate what articulated section 3 was subject to
Pressure equally can reduce the pressure that articulated section 3 is subject to by the way that back-up roller wheel 9 is arranged, to extend the use longevity of articulated section 3
Life.When the pressure that articulated section 3 is subject to becomes smaller, then the frictional force between door-plate 4 and articulated section 3 also becomes smaller, and staff pushes away at this time
It is more light when dynamic door-plate 4.
