Abstract
Description
Technical Field
[0001] This utility model relates to a fire-fighting device, and more particularly to a fire rescue backpack used in conjunction with an air respirator. Background Technology
[0002] In fire rescue operations, fire hoses and breathing apparatus are essential core equipment for firefighters. Their carrying efficiency directly affects the response speed and operational effectiveness of fire fighting and rescue. Currently, firefighters usually carry breathing apparatus on their backs and a coil of fire hose in each hand. However, for situations like high-rise rescues, more fire hoses are often needed. Therefore, firefighters need to travel back and forth between the rescue site and the equipment storage point. Frequently going up and down stairs not only consumes a lot of physical strength but also seriously delays the opportunity to extinguish the fire. Summary of the Invention
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a fire rescue backpack for use with an air respirator.
[0004] The technical solution adopted by this utility model to solve its technical problem is: A fire rescue backpack for use with an air respirator includes a backpack body, which is a hollow frame body formed by welding several metal strips. The frame body is divided into a left area for placing a water hose, a middle area for placing an air respirator, and a right area for placing a water hose in the left-right direction. The left area and the right area are symmetrically arranged. A fixing ring for mounting the air respirator is provided at the upper end of the side of the middle area closest to the human body. A limiting part that abuts against the top of the air respirator is connected to the upper side of the fixing ring.
[0005] The shape of the limiting part is similar to the top shape of the air respirator.
[0006] An empty area is provided on the side of the middle area away from the human body.
[0007] Reinforcing strips are welded to the upper two sides of the middle region, and the fixing ring is welded to the reinforcing strips.
[0008] The reinforcing strip and the limiting part are integrally stamped.
[0009] The beneficial effects of this utility model are as follows: This utility model consists of a hollow frame body formed by welding several metal strips. The frame body is divided into a left area for placing water hoses, a middle area for placing air respirators, and a right area for placing water hoses along the left-right direction. The left and right areas are symmetrically arranged. A fixing ring for mounting the air respirator is provided at the upper end of the side of the middle area closest to the human body. A limiting part that abuts against the top of the air respirator is connected to the upper side of the fixing ring. The air respirator is inserted into the fixing ring from bottom to top, and then the air respirator is carried on the back. The fixing ring serves as a fixing point, and the lower side of the frame body naturally fits against the firefighter's back. It is convenient to use, can be used with the firefighter's own air respirator equipment, requires no additional modifications, is low in cost, and realizes the integrated carrying of water hoses and air respirators, improving carrying stability and rescue efficiency. Attached Figure Description
[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0011] Figure 1 This is a structural diagram of the present invention; Figure 2 This is a schematic diagram of the present invention after it has been inserted into an air respirator; Figure 3 This is a top view of the present invention. Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0013] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0014] The following describes some embodiments of the present invention with reference to the accompanying drawings.
[0015] Reference Figure 1-3 A fire rescue backpack for use with an air respirator includes a backpack body, which is a hollow frame body formed by welding several metal strips. The frame body is divided into a left area 1 for placing fire hoses, a middle area 2 for placing air respirators, and a right area 3 for placing fire hoses along the left-right direction. This allows for the simultaneous carrying of fire hoses and air respirators, eliminating the need for firefighters to travel back and forth to retrieve equipment. It is especially suitable for complex rescue scenarios such as high-rise buildings, effectively reducing the number of times equipment needs to be transported and shortening the rescue response time.
[0016] The upper end of the middle region 2, near the human body, is provided with a fixing ring 4 for mounting an air respirator. The upper side of the fixing ring 4 is connected to a limiting part 5 that abuts against the top of the air respirator. The shape of the limiting part 5 is similar to the shape of the top of the air respirator. In use, the air respirator is inserted into the fixing ring from bottom to top (e.g., ...). Figure 2 As shown), the limiting part 5 naturally limits the air respirator. When a firefighter carries the air respirator on their back (the air respirator itself has a carrying strap, attached...), Figure 2 (The carrying straps are not shown in the picture.) The backpack can be carried at the same time, which is convenient to use. When the backpack is lifted up, the air respirator can be separated from the backpack, which is also convenient to disassemble.
[0017] Furthermore, reinforcing strips 7 are welded to the upper two sides of the middle area 2, and the fixing ring 4 is welded to the reinforcing strips 7. The reinforcing strips 7 and the limiting part 5 are integrally stamped to enhance the overall strength of the backpack body, prevent the equipment from shaking during travel, and ensure the stability and safety of carrying.
[0018] The left region 1 and the right region 3 are symmetrically arranged, and the middle region 2 has an empty region 6 on the side away from the human body, so that the overall center of gravity of the backpack after loading equipment is close to the human body, avoiding extra force caused by the center of gravity shift, significantly reducing the physical exertion of firefighters during the movement, and reducing fatigue and the risk of falling.
[0019] The main frame adopts a hollow design with welded metal strips, which greatly reduces the weight of the backpack while ensuring structural strength. The metal strips are welded to the reinforcing strips 7, limiting parts 5, fixing rings 6, etc., which further optimizes the structural load-bearing performance and balances lightweight and durability.
[0020] Furthermore, the metal strip can be made of high-strength aluminum alloy, which has a relatively low cost and a density of about 2.7 g / cm³, thus balancing low cost and light weight. In addition, the welding points between the metal strips are all passivated and rust-proofed to improve service life.
[0021] In this invention, the term "multiple" refers to two or more items unless otherwise expressly defined. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items. The terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
