Problems solved by technology
[0002] If the oxygen chamber door is suddenly opened during work, the pressure difference between the inside and outside of the oxygen chamber will be too large, which will cause damage to the patient. In order to ensure the safety of the patient in the oxygen chamber, the oxygen chamber standard stipulates that the locking pressure of the oxygen chamber door should not be More than 0.02MPa, the reset pressure is not more than 0.01MPa
However, the interlock mechanism structure of the oxygen chamber door is relatively complicated at present, and it cannot be well guaranteed that when the oxygen chamber uses a quick-opening door, the door can only be opened in a safe state

The invention discloses a quick-opening door interlocking mechanism for an oxygen cabin. The mechanism comprises an interlocking cylinder, the interlocking cylinder is a steel pressure-bearing piece, a stepped through hole is arranged in the interlocking cylinder, a piston rod is arranged in the stepped through hole, a gland is arranged at the other end of the stepped through hole, parts in the interlocking cylinder can be conveniently mounted and taken out, the gland is connected with an air tap outer tooth, the other end of the air tap outer tooth is connected with a corrugated hose, and the other end of the corrugated hose is connected with the interior of the oxygen cabin. The locking pressure of a cabin door is not greater than 0.02 MPa, the reset pressure is not greater than 0.01 MPa, the cabin door can be opened only in a safe state, the structure is simple, the operation is flexible, and the quick-opening door of the oxygen cabin can be locked and reset according to the internal pressure of the oxygen cabin.
Description
Technical field [0001] The present invention belongs to the field of mechanical electrification, and in particular to a quick-opening chain mechanism for oxygen chamber. Background technique [0002] When the oxygen chamber suddenly opens the door, it will cause the internal and external pressure to be too large, thereby causing damage to the patient. In order to ensure the safety of patients in the oxygen, the oxygen chamber standard specifies the locking pressure of the oxygen cabin. More than 0.02 MPa, the reset pressure is not more than 0.01 MPa. However, the main chain structure of the oxygen cabin is more complicated, and it is not possible to ensure that when the oxygen chamber is opened, the hatch can only be turned on in a safe state. Inventive content [0003] In order to solve the above problems, it is an object of the present invention to provide a quick-opening locking mechanism for oxygen chamber. [0004] A quick-opening chain mechanism for an oxygen chamber, incl...
