Description
Technical field
The utility model relates to construction safety fields, in particular to closed guard gate.
Background technique
Closed guard gate is exactly the door of people's protection works entrance, and closed guard gate's classification has common single, double fan to protect than sharper
Sealed door and sealed door, a variety of defense equipments such as the single, double fan airtight blast door of movable sill and sealed door.
Closed guard gate is mainly made of doorframe and door body, and doorframe is poured integrally by concrete and building, and door body is by steel
Shell processed and the armored concrete composition for being filled in inside, therefore its door body is than heavier.Under normal circumstances, door body is in open shape
State, the channel as walk.When emergency occurs, door body is closed.Since door body is heavier, open for a long time
Its hinged place with doorframe of state is easy stress and deformation occurs, and door body is caused to be not easy to open and close.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is that a kind of company of closed guard gate, door body and doorframe
The place of connecing is not susceptible to deformation, facilitates opening and closing.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of closed guard gate, including
Doorframe and the hinged door body and door lock mechanism of doorframe, the door body bottom is fixed with mounting plate, is fixed on the mounting plate
Shaft is socketed a turning set in the shaft, axially opens up a strip groove along the turning set and at least one end is run through, and described turn
The outer wall and door body bottom interval of dynamic set are arranged, and place a stripe board in the shaft, it is most upper that the strip groove is in turning set
When just and being located at door body bottom, stripe board is inserted into strip groove and stripe board abuts door body bottom.
Door body is in the state procedure opened or closed, at this time since turning set and door body interval are arranged without rubbing
It wipes, turning set abuts ground and rotates relative to shaft, to facilitate the closing of door；In contrast mounting plate, shaft (are installed at this time
Plate is comparatively relatively thin, is easily deformed；Shaft is relatively thin, is also easy to be broken under for a long time by shearing force) it is easy permanent stress
And lead to deformation, when door body is in the state for staying open or closing, stripe board is inserted into strip groove, so that stripe board abuts door
Body bottom, by stripe board, live-roller to ground, and in the process, shaft main function is to reduce to turn to the gravity of door body at this time
Dynamic set compression deformation.
Further, the strip groove is arranged three along turning set circumferential direction uniform intervals.
Strip groove is arranged three, on the one hand can be convenient using strip groove as impetus and carries out rotation adjusting to turning set, with
So that one of strip groove is located at door body bottom, to abut after guaranteeing stripe board insertion strip groove with door body bottom；It is another
Aspect is arranged three strip grooves and guarantees that one of strip groove turning set at door body bottom does not open up the side abutting of strip groove
Ground.
Further, the shaft is located at turning set two sides and is respectively inserted into a positioning pin.
The setting of positioning pin can prevent turning set axial dipole field.
Further, a placing groove is opened up in the shaft, places two pieces of limited blocks, the limited block in the placing groove
The cambered surface being affixed with one with turning set outer surface.
Limited block is located at turning set two sides for placing ground, places turning set and rotates in door body opening state.
Further, plane where the slot bottom of the strip groove is parallel with the axis of turning set, the upper end of the stripe board
Face, lower end surface are arranged in parallel, and the lower end surface of stripe board is abutted with the slot bottom of strip groove.
This mode stripe board and strip groove, door body bottom are face contact, and stripe board force dispersion is hardly damaged.
Further, the Axis Cross and/or stripe board of plane and turning set where the slot bottom of the strip groove have one
Inclined-plane.
So, it is ensured that stripe board is abutted with strip groove, door body bottom, but stripe board is possible to send out with door body bottom
Raw line contact, so that stripe board is easy stress and concentrates deformation.
Further, the door lock mechanism includes a drive rod, the driving assembly for driving drive rod to move up and down vertically, consolidates
The limit sleeve that is scheduled in door body, the locking level being threaded through in limit sleeve, both ends respectively the connecting rod hinged with drive rod and locking level,
Lock hole corresponding with locking level is provided on doorframe.
Driving assembly drives drive rod vertical direction mobile, drive rod by connecting rod drive locking level move horizontally be inserted into or
It is detached from lock hole.
Further, the driving component include the annular groove opened up along drive rod axially spaced-apart, with annular groove meshing gear, with
The drive shaft of door body, the turntable fixed with drive shaft are fixed and be pierced by gear.
By rotating turntable, gear movement is driven, it is mobile that gear engages belt wheel transmission bar with drive rod.
Further, the locking level is respectively arranged two in upper end, the lower end of drive rod, the corresponding company of each locking level
Bar, a limit sleeve, a lock hole.
Four locking levels are arranged such, door body is closed more reliable.
Further, rubber slab is caught in the strip groove, the outer surface of the rubber slab and the peripheral wall of turning set are concordant.
In this way, keeping the friction of turning set and ground when door body rotation；When door body is opened or locked, it is taken out
In a rubber slab, stripe board is put into.
In conclusion the utility model has the following beneficial effects: the door body of the closed guard gate and the junction of doorframe are not easy
Deformation occurs, facilitates opening and closing.
