Specific implementation mode
The utility model is described further with reference to attached drawing.
Embodiment one:
As shown in Figure 1, a kind of reinforced concrete protection sealing door, including doorframe 1 and the door leaf 2 for being rotationally connected with doorframe 1.
Door leaf 2 includes metal frame 3, is fixedly connected on receiving frame 4 and concrete section 5 of the metal frame 3 towards 1 one end end face of doorframe.Coagulation
5 pouring molding of native portion is in metal frame 3 and accommodates in frame 4.As shown in Fig. 2, grid is provided with several stiffeners 6 in metal frame 3,
Stiffener 6 is located in concrete section 5.As shown in Figure 1, doorframe 1 is circumferentially with sealing strip 7 close to 2 side of door leaf along doorframe 1.
The closing and unlatching of doorframe 1 are realized by turning door leaf 2.When door leaf 2 closes doorframe 1, accommodates frame 4 and be located at door
In frame 1, sealing strip 7 pushes against metal portion.
As shown in Figure 1, in order to make door leaf 2 that can be stably maintained at the state of closing doorframe 1,1 side of doorframe is equipped with slot 8,
Slot 8 is equipped with several along 1 short transverse of doorframe.Rotation connection is useful for being rotatably inserted into the bolt 9 of slot 8 on door leaf 2.Door leaf
Drive shaft 10 is rotatably connected on 2, drive shaft 10 passes through door leaf 2.As shown in figure 3, one end is radially solid outwardly for drive shaft 10
Surely it is provided with force application rod 11.As shown in Figure 1, being equipped with linkage mechanism 12 between drive shaft 10 and bolt 9, linkage mechanism 12 can drive
Bolt 9 is driven to rotate when moving axis 10 rotates.
As shown in figure 4, linkage mechanism 12 includes turning set 13, connecting rod 14 and the interlocking bar 15 for being rotationally connected with door leaf 2.
Drive shaft 10 passes through one of turning set 13 and is fixedly connected on turning set 13, and bolt 9 is radially arranged and consolidates along turning set 13
Surely it is connected to turning set 13.Connecting rod 14 is radially arranged along rotation axis and is fixedly connected on turning set 13.The rotation of interlocking bar 15 connects
It is connected to all connecting rods 14.
When drive shaft 10 rotates, turning set 13 can be driven to rotate, and then connecting rod 14 is driven to rotate, and pass through interlocking bar
15 drive all connecting rods 14 to rotate, i.e., all turning sets 13 rotate, and bolt 9 is made to be transferred in slot 8, realize door leaf 2 and doorframe 1
Fixation.
As it can be seen in figures 5 and 6, in order to adjust suffered resistance when drive shaft 10 rotates, that is, adjusts door leaf 2 and lock doorframe 1
Or the resistance overcome needed for being freely rotated with respect to doorframe 1,2 side of door leaf are fixedly connected with installation set 16, installation set 16 is arranged
Outside turning set 13 and it is rotationally connected with drive shaft 10.16 outer wall of installation set offers arc groove 17, turning set 13 along its circumferential direction
It is radially threaded with connection bolt 18, connection bolt 18 passes through arc groove 17 and is slidably connected to arc groove 17.
As shown in fig. 7, being fixedly connected with installation axle 19 on door leaf 2, installation axle 19 includes light bar segment 20 and spiro rod section 21.Turn
Dynamic set 13 is sheathed on outside light bar segment 20 and is rotationally connected with light bar segment 20, and spiro rod section 21 is threaded with installation nut 22.Polished rod
Section 20, which is arranged with, abuts gasket 23, abuts gasket 23 and is located between installation nut 22 and turning set 13 and is connected to installation nut 22
With turning set 13.
By screwing installation nut 22 and connection bolt 18, you can the required resistance overcome when turning set 13 rotates is adjusted,
And then adjust suffered resistance when drive shaft 10 rotates, that is, it adjusts door leaf 2 and locks doorframe 1 or can be freely rotated with respect to doorframe 1
The required resistance overcome.Reduce the probability for causing door leaf 2 to be opened since maloperation causes bolt 9 to leave slot 8.
As shown in Figure 1, the sealed door does seal tightness test for convenience, doorframe 1 is equipped with back to 2 side of door leaf for closed
The coffer 24 of doorframe 1.After sealed door makes, doorframe 1 can be closed by door leaf 2, then the sealed door is sealed
Property experiment, after the completion of experiment, then cut away coffer 24.
The operation principle of the airtight blast door is as follows:
The closing and unlatching of doorframe 1 can be realized by 1 turning door leaf 2 of opposite doorframe;If door leaf 2 need to be made to maintain closing
The state of doorframe 1 then only need to rotate drive shaft 10 by force application rod 11.Drive shaft 10 rotates at this time, in the work of linkage mechanism 12
It is rotated with lower drive bolt 9, bolt 9 is made to be transferred to slot 8.Come make door leaf 2 with respect to doorframe 1 fix, allow door leaf 2 to be stably held in pass
Close the state of doorframe 1.If door leaf 2 need to be opened, force application rod 11 need to be only rotated backward.
If the very comfortable when rotating drive shaft 10, easily since maloperation rotates drive shaft 10, installation nut 22 can be screwed
With connection bolt 18, the required resistance overcome when turning set 13 rotates is adjusted, and then adjusts suffered resistance when drive shaft 10 rotates.
Reduce since maloperation leads to the probability that drive shaft 10 rotates.
Embodiment two:
Embodiment two and embodiment one difference lies in:
As shown in figure 8,1 both sides of doorframe are equipped with slot 8, and door leaf 2 is equipped with the bolt 9 of corresponding slot 8.Door leaf 2 is every
Side corresponds to a linkage mechanism 12 respectively.Two linkage mechanisms 12 are symmetrical set along the center line of 2 width direction of door leaf and edge
The center line of 2 length direction of door leaf is symmetrical set.
If door leaf 2 need to be opened, 10 rotation directions of two drive shafts 10 of rotation and two drive shafts are needed to need opposite.The behaviour
Work can reduce due to maloperation and all bolts 9 is caused all to leave slot 8, and doorframe is closed in being maintained at of making that door leaf can be more stable
State.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
