Abstract
The utility model discloses a ten-point anti-explosion locking door for a refuge chamber, which comprises a door body and a door frame. The middle of the door body is provided with a rotating handle, rotatable locking tongues are arranged on the edge of the periphery of the door body, the rotating handle is in driving connection with a gear mechanism, a connecting rod mechanism is connected between the gear mechanism and the locking tongues, and when the gear mechanism rotates, the connecting rod mechanism drives all the locking tongues to lock or open the door body together. The ten-point anti-explosion locking door for the refuge chamber has the advantages that 1 by means of the ten-point locking tongues, the door can be simultaneously locked vertically and horizontally, and stress is evenly distributed on the door frame, thereby being strong in impact resistance capability and improving safety degree. 2 the locking tongues and inclined wedges are locked in contacting mode, and the locking is tighter along with the rotating of the rotating handle, thereby reliably preventing toxic and harmful gas from entering the chamber and protecting life safety of people, and 3 by means of the inner-outer double-direction coaxial rotating handle, users can open and lock the door from both the inside and the outside.
Description
Technical field
The utility model relates to a kind of door, and particularly a kind of refuge chamber is with 10 explosion-proof locking doors.
Background technology
Refuge chamber is to take place when disaster, when personnel can't withdraw from, and the shelter that invasion and attack poisonous for preventing, pernicious gas are set up.In the self-rescue of miner, it is very necessary that refuge chamber is set.Because self-rescuer is shorter effective time, after wearing self-rescuer, in its effective acting time, can not arrive safety place or route of withdrawal can't through the time, self-rescuer is perhaps arranged and pernicious gas content when higher, refuge chamber can play a role.
Refuge chamber generally is equipped with thickening steel explosion proof door, and superpower anti-superpressure can be born the pressure up to 15psi (0.10Mpa) unit, can in the underground emergency incident, protect refuge chamber.But the explosion proof door of at present common refuge chamber just gets locking on one side at door; Locking effect is undesirable, and poor reliability can not stop the intrusion of toxic and harmful in case the explosion-proof door lock of refuge chamber is not tight; Reduce the explosion-proof impact capacity, accident personnel's life security in serious threat.
Summary of the invention
Be technical deficiency more than solving, the utility model provides a kind of locking effect is good, the capability of antidetonance is high refuge chamber with 10 explosion-proof lockings doors.
The utility model is realized through following measure:
A kind of refuge chamber of the utility model comprises a body and doorframe with 10 explosion-proof locking doors, said door body
The middle part is provided with turning handle; The edge of door body is provided with rotating dead bolt; Said turning handle drives and is connected with gear mechanism, is connected with between said gear mechanism and the dead bolt when gear mechanism rotates, to drive the common locking of all dead bolts or make the linkage of opening door body.
Preferably, the left and right sides of above-mentioned door body evenly is provided with 4 respectively and is rotatably connected on the vertical connecting rod
Dead bolt; Left side first dead bolt is connected with the gear mechanism left end through connecting rod; Right side the 4th dead bolt is connected with the gear mechanism right-hand member through connecting rod; Door body upside is provided with the upper lock tongue that links to each other with right side second dead bolt through connecting rod, and door body downside is provided with the following dead bolt that links to each other with left side the 3rd dead bolt through connecting rod, and said connecting rod junction is and is rotationally connected.
In order to lock tightlyer, position corresponding with each dead bolt on the above-mentioned doorframe is provided with wedge.
Above-mentioned turning handle is inside and outside bidirectional coaxial turning handle, inside and outside door, all can open and close.
In order to improve sealing effectiveness, above-mentioned door body edge is provided with sealing joint strip.
Observe for ease, above-mentioned door body is provided with observation port.
The beneficial effect of the utility model is:
1. adopt 10 dead bolts, make door in locking simultaneously up and down, doorframe is stressed to be uniformly distributed with, and strong shock resistance has improved safe coefficient.2. adopt dead bolt to contact locking with wedge, change tighter and tighter with turning handle, good seal reliably stops poisonous have, do harm to gas entering chamber, protection people's life security.3. through inside and outside bidirectional coaxial turning handle, personnel all can be from inside and outside switch, this door of locking.
