Description
Technical Field
The utility model relates to a mining self-rescuer technical field, more specifically say, relate to a chucking formula quick-operation joint for connecting self-rescuer and breathing full face guard.
background
The self-rescuer is a life saver and a safety device for coal mine workers, and when major disaster accidents such as gas explosion occur in a coal mine, people in danger can escape from disaster areas and save lives by wearing the self-rescuer which can play a respiratory protection role. China 'coal mine safety regulations' stipulate: personnel entering the well must carry the self-rescuer with them; therefore, most coal mines in China are equipped with mine self-rescuer for miners entering the mine. When people escape in danger and wear the self-rescuer, the teeth cushion in the mouth set must be bitten by mouth and the nose must be clamped by the nose clip set, so that the aim is to allow the clean air in the self-rescuer to be breathed only by mouth, and not to allow the poisonous and harmful gas in the surrounding environment to be breathed by nose.
However, when a major disaster accident occurs, there are many cases that underground workers have no time to wear the self-rescuer or are trapped and cannot use the self-rescuer effectively, and at this time, rescue workers need to carry a plurality of breathing masks and a plurality of oxygen bottles to rescue trapped people; because the oxygen cylinder has certain weight, the rescuer once can not carry too much, can influence rescue efficiency like this, and oxygen cylinder is gone with to the ware of saving oneself in the pit, consequently need research and development a mining self-rescuer quick-operation joint, lets the rescuer when the rescue is stranded, can only carry the respirator of installing quick-operation joint, can effectually utilize the oxygen cylinder of ware of saving oneself in the pit like this, and the rescuer can not carry the oxygen cylinder and carry respirator more like this, improves rescue efficiency.
SUMMERY OF THE UTILITY MODEL
To the above defect, the utility model provides a chucking formula quick-operation joint for connecting self-rescuer and breathing full face guard.
in order to achieve the above purpose, the utility model adopts the following technical scheme:
a clamping type quick connector for connecting a self-rescuer and a breathing full mask comprises an air hose; one end of the ventilation hose is communicated with the breathing mask, the other end of the ventilation hose is communicated with a ventilation hole formed in the sealing plug, and one end, far away from the breathing mask, of the ventilation hose is fixed with the sealing plug; a locking block is fixed on the ventilation hose, a rack mounting groove is formed in the locking block, a rack is inserted in the rack mounting groove, one end of the rack extends out of the rack mounting groove and is fixed with a connecting plate, and a pressing block is fixed at one end, far away from the rack, of the connecting plate; the lock is characterized in that a lock tongue mounting groove is formed in the lock block, a lock tongue is inserted in the lock tongue mounting groove, one end of the lock tongue is in contact with the rack, a pull rod is fixed to one end, away from the rack, of the lock tongue, the pull rod extends out of the lock tongue mounting groove, a compression spring is arranged between the right side wall of the lock tongue and the right side wall of the lock tongue mounting groove, and the compression spring is sleeved on the pull rod.
Furthermore, a unlocking ring is fixed on the pull rod extending out of the bolt mounting groove.
the utility model has the advantages that: this device can utilize the oxygen cylinder of ware of saving oneself in the pit, when letting the rescuer rescue the trapped person, only carries the respirator who installs quick-operation joint, and the rescuer can not carry the oxygen cylinder like this and carry respirator more, improves rescue efficiency.
