A durable corrugated inflatable respirator

Abstract

The invention discloses a durable corrugated inflatable respirator, which includes a respirator body, a disassembly mechanism A and a disassembly mechanism B. The disassembly mechanism A includes a first round cover, a fixing column, a fixing groove, a through pipe, a second Round cover, moving slot, buffer pad, pull block, pull rod, pad and return spring, the left end of the respirator body is fixedly connected with the right side of the first round cover, and the right side of the fixed column is connected with the first round cover The left side of the fixed column is fixedly connected, the right end of the through pipe is fixedly connected with the left side of the second round cover, and the left top of the fixed column is provided with a fixing groove. Column, fixed groove, through pipe, second round cover, moving groove, buffer pad, pull block, pull rod, cushion block and return spring. When it needs to be disassembled, pull the two pull rods in opposite directions by hand, and the return spring will stretch out. Long, so that the pull rod escapes from the fixing groove, achieving a good disassembly effect.

Description

technical field [0001] The invention relates to the technical field of respirators, in particular to a durable corrugated inflatable respirator. Background technique [0002] The respirator is a self-contained open-air respirator, widely used in firefighting, chemical industry, shipbuilding, petroleum, smelting, warehouses, laboratories, mines and other departments, for firefighters or emergency rescue personnel It can safely and effectively carry out fire extinguishing, emergency rescue and rescue work in various environments such as oxygen and oxygen. This series of products is equipped with a full-face mask with a wide field of view, bright and good airtightness, and the air supply device is equipped with a new type of air supply valve with small size, light weight and stable performance; high-strength backboard and high-quality high-pressure with high safety factor are selected. Gas cylinder; the pressure reducing valve device is equipped with a residual gas alarm, with...

AI Technical Summary

Problems solved by technology

[0003] The existing respirator is installed at the end of the pipe connecting the oil conservator to the air, and in areas affected by the monsoon climate all year round and with high air humidity, the internal pressure of the transformer changes greatly every time the transformer oil expands with heat and contracts with cold. This leads to the easy discoloration of the silica gel in the transformer respirator

Since more than two-thirds of the discolored silica gel in the transformer respirator needs to be replaced, and the location of the substation is widely distributed, the work of replacing the silica gel of the transformer respirator will consume a lot of manpower and material resources

When replacing the silica gel in the existing transformer respirator, it is necessary to remove the transformer respirator from the transformer exhaust pipe first, then replace the silica gel in the transformer respirator, and then install the transformer respirator to the transformer after replacing the silica gel. On the exhaust pipe, because the installation device is too complicated, the disassembly is also extremely complicated, resulting in low disassembly efficiency and increasing the burden on the staff
