Description
Technical Field
[0001] The utility model relates to the technical field of escape devices for fire evacuation passages, in particular to an escape device for fire evacuation passages. Background Art
[0002] Self-rescue respirators are essential self-rescue, mutual rescue and escape devices for individuals in the event of fire accidents in hotels, restaurants, shopping malls, banks, entertainment venues, high-rise residential buildings, postal services, telecommunications, electricity, machinery, subways, water transport, forestry, oil refining, chemical industry and other enterprises and institutions. When a fire occurs, self-rescue respirators are often used when evacuating from fire passages to avoid smoke damage to the respiratory tract.
[0003] The inventor discovered during daily use of a self-rescue respirator that the filter on the surface of a general self-rescue respirator is fixed on the surface of the respirator. Since the filter is fixed on the surface of the self-rescue respirator, the self-rescue respirator cannot be used again after use, which causes problems. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an escape device for a fire evacuation passage.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an escape device for a fire evacuation passage, comprising a respirator, a convenient replacement device is provided on the side of the respirator, a filter is provided on the side of the respirator, an elastic band is fixedly connected to the side of the respirator, a sealing device is provided inside the respirator, the convenient replacement device comprises a hollow rod fixedly connected to the surface of the respirator, a clamping ring is fixedly connected to the surface of the hollow rod, a sleeve rod is sleeved on the surface of the hollow rod, an annular groove is provided on the inner wall of the sleeve rod, and a filter is fixedly connected to one end of the sleeve rod.
[0006] The effect achieved by the above components is: under the action of the clamping ring and the ring groove, the sleeve rod can be stuck on the surface of the hollow rod, and then the filter can be fixed on the surface of the respirator. When using the respirator, the respirator is covered on the face and fixed to the mouth and nose through the elastic band. The smoke is filtered out through the filter, so that the breathed gas is the police gas. The person bends down and runs out of the room through the fire evacuation passage, thereby achieving the purpose of escape.
[0007] Preferably, a rectangular groove is provided on the surface of the hollow rod, and a protrusion is fixedly connected to the interior of the sleeve rod.
[0008] The effect achieved by the above components is that, under the action of the rectangular groove and the protrusion, the sleeve rod will not rotate when it is sleeved onto the surface of the hollow rod.
[0009] Preferably, a circular groove is provided on the inner wall of the sleeve rod, a groove is provided on the surface of the hollow rod, and a locking ball is provided on the inner wall of the circular groove, and the locking ball is locked into the interior of the groove.
[0010] The effect achieved by the above components is: under the action of the clamping ball, the sleeve rod can be fixed on the surface of the hollow rod, and half of the clamping ball is inserted into the groove, thereby achieving the fixing effect and facilitating disassembly.
[0011] Preferably, a spring is fixedly connected to the inside of the circular groove, and the other end of the spring is fixedly connected to the surface of the locking ball.
[0012] The effect achieved by the above components is that, under the action of the spring, the card ball can be inserted into the groove without retracting.
[0013] Preferably, one end of the hollow rod is fixedly connected to a sealing ring, and the sealing ring is in contact with the inner wall of the sleeve rod.
[0014] The effect achieved by the above components is: under the action of the sealing ring, smoke will not enter the respirator through the gap between the sleeve rod and the hollow rod. After the respirator is used, the sleeve rod is pulled out from the surface of the hollow rod, the filter is replaced, and the new sleeve rod is sleeved on the surface of the hollow rod. Under the action of the clamping ring and the ring groove, the sleeve rod can be stuck on the surface of the hollow rod, thereby fixing the filter on the surface of the respirator. Under the action of the clamping ball and the spring, the sleeve rod can be firmly fixed on the surface of the hollow rod. When the sleeve rod is sleeved on the hollow rod, the protrusion slides inside the rectangular groove, so that the sleeve rod will not rotate. Since half of the clamping ball is inserted into the groove, the fixing effect is achieved and the disassembly is convenient. Under the action of the sealing ring, smoke will not enter the respirator through the gap between the sleeve rod and the hollow rod, thereby facilitating the replacement of the filter.
[0015] Preferably, the sealing device comprises an airbag fixedly connected to the inner wall of the respirator, and the airbag is deformable.
[0016] The effect achieved by the above components is that under the action of the airbag, the respirator can fit the face more snugly, avoiding the phenomenon of smoke entering between the respirator and the face.
[0017] Preferably, a baffle is fixedly connected to the interior of the respirator, and the baffle is a soft rubber plate.
[0018] The effect achieved by the above components is that, under the action of the baffle, the respirator will not leak when in use, thereby achieving a sealing effect.
[0019] Preferably, an elastic rope is fixedly connected to the surface of the baffle, and the other end of the elastic rope is fixedly connected to the side of the elastic band.
[0020] The effects achieved by the above components are: under the action of the elastic rope, when the respirator is worn, the baffle can be pulled so that the baffle can fit closely to the face, avoiding leakage. When a fire occurs and escape is needed, the respirator is worn on the face. Under the action of the airbag, the respirator can fit more closely to the face, avoiding the phenomenon of smoke entering between the respirator and the face. Under the action of the baffle, the respirator will not leak during use, thereby achieving a sealing effect. Under the action of the elastic rope, when the respirator is worn, the baffle can be pulled so that the baffle can fit closely to the face, avoiding leakage, thereby achieving a sealing effect.
[0021] Compared with the prior art, the advantages and positive effects of the present invention are:
[0022] The utility model provides a convenient replacement device. After the respirator is used, the sleeve rod is pulled out from the surface of the hollow rod, the filter is replaced, and the new sleeve rod is sleeved on the surface of the hollow rod. Under the action of the clamping ring and the ring groove, the sleeve rod can be clamped on the surface of the hollow rod, so that the filter can be fixed on the surface of the respirator. Under the action of the clamping ball and the spring, the sleeve rod can be firmly fixed on the surface of the hollow rod. When the sleeve rod is sleeved on the hollow rod, the protrusion slides inside the rectangular groove, so that the sleeve rod will not rotate. Since half of the clamping ball is inserted into the groove, the fixing effect is achieved and the disassembly is convenient. Under the action of the sealing ring, smoke will not enter the respirator from the gap between the sleeve rod and the hollow rod, so as to achieve the effect of convenient filter replacement, thereby solving the problem that the self-rescue filter cannot be recycled.
