Technical Field
[0001] This utility model relates to the field of fire-fighting suit technology, specifically a fire-fighting suit for indoor fire rescue. Background Technology
[0002] Indoor fire rescue refers to the use of various equipment and technical tactics by firefighters or other emergency personnel to evacuate and rescue people trapped by fire or threatened by other dangers in an indoor fire scene to a safe area. Indoor fire rescue requires professional firefighters to carry out rescue work. Firefighters cannot do without wearing fire suits during rescue, which can protect their bodies from injury and improve their safety.
[0003] Chinese patent discloses a fire suit for indoor fire rescue (publication number CN220801728U). This patented technology achieves the tightening of the cuffs of the fire suit through the use of an auxiliary mechanism. When entering the fire scene, the high-temperature resistant material of the fire suit can protect the tightening structure in the auxiliary mechanism. Through the combined use of the above structures, the problem of the cuffs deforming due to high temperatures when the Velcro at the tightening position of the fire suit is encountered when entering the fire scene, causing the cuffs to burst open. This also solves the problem of high temperatures entering the fire suit through the cuffs during rescue operations, causing discomfort to the rescuers.
[0004] However, most existing fire suits use Velcro to tighten the cuffs. This method can cause the Velcro to detach when heated, allowing external smoke to enter the suit and harm firefighters. As mentioned in the comparative document, other methods use rubber strips and zippers for tightening. In practical applications, using multiple structures like zippers and rubber strips for tightening is inconvenient and hinders indoor fire rescue operations. Therefore, those skilled in the art provide a fire suit for indoor fire rescue to address the problems mentioned in the background section. Utility Model Content
[0005] The purpose of this invention is to provide a fire-fighting suit for indoor fire rescue, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0028] Example 1:
[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a fire suit for indoor fire rescue, including a main body 1, a collar 11 on the upper part of the main body 1, sleeves 13 on both sides of the main body 1, and reflective strips 12 on the outside of the main body 1 and sleeves 13. A positioning plate 3 is provided on the outside of the sleeves 13, and fixing rods 35 are symmetrically arranged on the inner side of the positioning plate 3. A spring 351 is provided inside the fixing rod 35, and an adjusting rod 33 is passed through one end of the fixing rod 35. One end of the lever 33 is connected to a limiting plate 34 inside the positioning plate 3. A push rod 32 is symmetrically arranged on one side of the limiting plate 34, and a tension rope 31 is passed through the limiting plate 34 and the positioning plate 3. This arrangement uses the push rod 32 to push the limiting plate 34 away from the inside of the positioning plate 3, and the tension rope 31 is pulled to tighten the sleeve 13, thereby preventing smoke from entering the fire suit body 1 through the gap of the sleeve 13 and causing injury to firefighters.
[0030] The inner side of the main body 1 of the fire suit is also provided with an inner liner 2. The inner liner 2 includes a first flame-retardant layer 21 and a second flame-retardant layer 24 arranged from the inside to the outside of the main body 1 of the fire suit. A filling layer 22 is filled between the first flame-retardant layer 21 and the second flame-retardant layer 24. An antistatic layer 25 is also provided on the outside of the second flame-retardant layer 24. An adhesive layer 23 is provided on the inside of the first flame-retardant layer 21. This arrangement utilizes the first flame-retardant layer 21 and the second flame-retardant layer 24 in the inner liner 2 to enable the main body 1 of the fire suit to have a highly efficient flame-retardant purpose. The filling layer 22 can improve the flame-retardant effect, so as to provide efficient protection for firefighters.
[0031] Example 2:
[0032] The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details:
[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the elastic cord 31 is further arranged in a ring inside the sleeve 13, and one end of the elastic cord 31 passes through the outside of the sleeve 13. This arrangement can achieve the purpose of tightening the cuff of the sleeve 13 of the fire suit body 1 by pulling the elastic cord 31, so as to prevent smoke from entering the cuff of the sleeve 13 and entering the interior of the fire suit body 1 and causing injury to firefighters.
[0034] like Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, one end of the push rod 32 passes through the outer side of the positioning plate 3, and two sets of fixing rods 35 are symmetrically arranged on the inner side of the positioning plate 3. One end of the spring 351 is fixed to the inner end of the fixing rod 35, and the other end of the spring 351 is fixed to one end of the adjusting rod 33. This arrangement utilizes the fact that when the push rod 32 pushes, the spring 351 will be squeezed and deformed inside the fixing rod 35. At this time, the elastic cord 31 can be pulled to achieve the purpose of tightening or loosening the cuff of the sleeve 13.
[0035] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the adhesive layer 23 is further adhered to the inner side of the fire suit body 1. The first flame-retardant layer 21 and the second flame-retardant layer 24 have the same thickness, and both the first flame-retardant layer 21 and the second flame-retardant layer 24 are ceramic fibers. The filling layer 22 is made of aramid fiber, and the antistatic layer 25 is made of conductive fiber. This arrangement utilizes the first flame-retardant layer 21 and the second flame-retardant layer 24 to enable the fire suit body 1 to have a highly efficient flame-retardant effect, and the filling layer 22 can further enhance its flame-retardant effect, ensuring the safety of firefighters.
[0036] Example 3:
[0037] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
[0038] Specifically, the fire suit used for indoor fire rescue is designed as follows: First, an inner liner 2 is installed inside the main body 1 of the fire suit. The inner liner 2 consists of a first flame-retardant layer 21, a filling layer 22, an adhesive layer 23, a second flame-retardant layer 24, and an antistatic layer 25. The first flame-retardant layer 21 and the second flame-retardant layer 24 enable the main body 1 of the fire suit to have a highly efficient flame-retardant effect. The filling layer 22 further enhances the flame-retardant effect of the main body 1 of the fire suit, ensuring the safety of firefighters. At the same time, the antistatic layer 25 reduces the risk of explosion caused by static electricity accumulation, thus improving the safety of firefighters.
[0039] Simultaneously, when tightening the cuffs of the sleeves 13 of the fire suit body 1, the push rod 32 is pushed to move the limiting plate 34, which causes the spring 351 inside the fixing rod 35 to be compressed and deformed. At this time, the elastic cord 31 can be pulled to tighten the cuffs of the sleeves 13. After tightening, the push rod 32 can be released to allow the spring 351 to return to its deformation, which in turn causes the limiting plate 34 to move in the opposite direction to press the elastic cord 31, ensuring the stability of the elastic cord 31. By tightening the cuffs of the sleeves 13 of the fire suit body 1, smoke can be prevented from entering the cuffs of the sleeves 13 during indoor fire rescue and causing injury to firefighters.
[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
