Abstract
Description
Technical Field
[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a double-cylinder fixing bracket for breathing apparatus. Background Technology
[0002] In many fields involving hazardous environments or requiring a high oxygen supply, such as industrial production, fire rescue, and mining operations, self-contained breathing apparatus (SCBA) is a crucial piece of equipment for ensuring the safety of workers and enabling normal operations. However, current traditional SCBAs generally only accommodate a single air cylinder, typically with capacities of 6.8L, 8L, or 9L.
[0003] Due to the limited capacity of a single gas cylinder, operators face a severe shortage of gas supply time, only able to maintain operations for approximately 15-30 minutes. In complex and time-consuming work scenarios, such as prolonged firefighting operations, rescue operations deep in underground mines, and maintenance work on large chemical plants, frequent cylinder changes not only significantly impact work efficiency but also pose potential safety risks to workers due to delays during the replacement process.
[0004] With advancements in passive exoskeleton technology, rescuers can now carry more air cylinders. However, existing dual-cylinder mounting solutions typically involve pre-installing space for two cylinders on the breathing apparatus backplate. This method has significant drawbacks, as it substantially increases the area of the backplate, leading to a substantial increase in its overall weight. This negatively impacts the operator's mobility and comfort, reducing their ability to respond to hazardous environments and their operational efficiency.
[0005] Therefore, there is an urgent need for a dual-cylinder mounting bracket that can effectively increase the amount of air cylinders carried without excessively increasing the area and weight of the breathing apparatus backplate. Utility Model Content
[0006] The present invention provides a dual-cylinder fixing bracket for breathing apparatus, which can effectively increase the amount of cylinders that can be carried. At the same time, the dual-cylinder fixing bracket is very compact and can be directly installed on the back panel, so as not to excessively increase the area and weight of the breathing apparatus back panel.
[0007] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:
[0008] Two gas cylinders 2 are installed on T-shaped component 1-1, and T-shaped component 1-1, together with gas cylinders 2, is installed on pressure reducer 1-2 at the bottom end of the back panel 1 of the air respirator;
[0009] A fixing bracket 1-3 is provided near the top of the back plate 1, and gas cylinder strap fasteners 1-4 are installed on both sides of the back plate 1.
[0010] Gas cylinder straps 1-5 pass through the fixed bracket 1-3 and the gas cylinder strap fastener 1-4 in sequence, binding the gas cylinder 2 to the fixed bracket 1-3.
[0011] The dual-cylinder fixing bracket for breathing apparatus provided in this embodiment is very compact. The two cylinders can be securely fixed to the back panel by means of cylinder straps and fixing bracket, so as to achieve the effect of fixing the dual cylinders without excessively increasing the area and weight of the breathing apparatus back panel.
