Self-falling waist strap

Abstract

The embodiment of the utility model discloses a self-dropping waist strap, which relates to the technical field of emergency rescue equipment, and is characterized in that the waist strap and an air exhalation back plate are connected by adopting a buckle connection structure and an adsorption connection structure at the same time, so that the fastening degree of a person wearing an air exhalation can be improved, and the safety of the person wearing the air exhalation can be improved. And the friction force provided by the adsorption connecting structure is smaller than the weight of the air exhalation, so that the air exhalation can conveniently and quickly fall off from the body of the fireman after the buckle is opened, and the special waist bridle device for the air exhalation back plate and the gas cylinder can be conveniently and quickly carried or separated by the fireman when the fireman emergently escapes.

Description

Technical Field

[0001] This utility model relates to the field of emergency rescue equipment technology, and in particular to a self-detachable waist belt. Background Technology

[0002] In hazardous operations such as firefighting and rescue, self-contained breathing apparatus (SCBA) is a crucial piece of equipment for ensuring the life safety of firefighters. Traditional SCBA consists of a backplate, an air cylinder, and shoulder straps and a waist belt connected to the backplate. Firefighters wear these components to secure the SCBA to their bodies so they can work and move in environments filled with smoke or toxic gases.

[0003] However, in emergency escape situations, such as sudden building collapses or rapid fire spread that obstructs escape routes, existing breathing apparatus (BBA) donning methods reveal significant shortcomings. Firstly, conventional BBA fastening methods are cumbersome and rigid. When firefighters need to quickly remove the BBA to adapt to new escape requirements, such as navigating narrow passages or climbing obstacles, traditional BBAs are difficult to detach quickly, potentially severely impacting escape speed and agility, and increasing the risk to life. Secondly, existing BBA connection designs lack a targeted, rapid self-detachment function. In emergencies, firefighters may be unable to efficiently disengage the various connections due to panic or time constraints, causing the BBA to become an obstacle to escape.

[0004] Furthermore, as fire and rescue missions become increasingly complex and diverse, higher demands are placed on the convenience, safety, and emergency response capabilities of firefighters' equipment. Currently, there is a lack of a dedicated waist belt device on the market that allows firefighters to quickly carry or detach from their breathing apparatus backplates and air cylinders during emergency escapes. Utility Model Content

[0005] The present invention provides a self-detachable waist belt that can improve the tightness of a person wearing a breathing apparatus, and the breathing apparatus can be easily and quickly removed from the person after the buckle is opened.

[0006] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0007] The waist belt (1) is fixed with a first waist belt (1.1) and a second waist belt (1.2) at both ends respectively. The first waist belt (1.1) is equipped with a waist belt connecting buckle male head (1.3) at each end.

[0008] The second section of the waist belt (1.2) has a male waist belt connector (1.3) and a female waist belt connector (1.4) installed at each end.

[0009] The waist belt (1) and the breathing apparatus back panel (2) are connected by both a buckle connection structure and an adsorption connection structure.

[0010] The self-detachable waist belt provided in this embodiment of the utility model adopts both a buckle connection structure and an adsorption connection structure between the waist belt and the breathing apparatus back panel. This can improve the tightness of the breathing apparatus worn by the personnel. Since the friction provided by the adsorption connection structure is less than the weight of the breathing apparatus, the breathing apparatus can be easily and quickly detached from the personnel after the buckle is opened. This makes it convenient for firefighters to quickly carry or detach the breathing apparatus back panel and air cylinder during emergency escape. Attached Figure Description

[0021] This utility model embodiment provides a self-detachable waist belt, such as Figure 1-7 As shown, it includes:

[0022] The waist belt (1) is fixed with a first waist belt (1.1) and a second waist belt (1.2) at both ends respectively. The first waist belt (1.1) is equipped with a waist belt connecting buckle male head (1.3) at each end.

[0023] The second section of the waist belt (1.2) has a male waist belt connector (1.3) and a female waist belt connector (1.4) installed at each end.

[0024] The waist belt (1) and the breathing apparatus back panel (2) are connected by both a buckle connection structure and an adsorption connection structure.

[0025] Specifically, the buckle connection structure includes: a male waist belt buckle connector (1.3) at one end of the first waist belt (1.1) is inserted into a female air-breathing connection connector (2.2) on the air-breathing back panel (2); a male waist belt buckle connector (1.3) at the other end of the first waist belt (1.1) is inserted into a female waist belt buckle connector (1.4) on the second waist belt (1.2); and a male waist belt buckle connector (1.3) on the second waist belt (1.2) is inserted into another female air-breathing connection connector (2.2) on the air-breathing back panel (2). The structure of the female air-breathing connection connector (2.2) is the same as that of the female waist belt buckle connector (1.4). The male waist belt buckle connector (1.3) can adopt the male connector structure shown in the figure, and the female air-breathing connection connector (2.2) and the female waist belt buckle connector (1.4) can adopt the female connector structure shown in the figure.

[0026] The adsorption connection structure includes: a waist belt connecting component (1.5) and a connecting component (2.1) on the breathing air lumbar support are attached and fixed together. The attachment method between the waist belt connecting component (1.5) and the connecting component (2.1) on the breathing air lumbar support includes: Velcro, magnetic snap, and concealed snap.

[0027] The friction generated by the waist belt connecting component (1.5) being attached and fixed to the connecting component (2.1) on the breathing apparatus waist support is less than the total weight of the breathing apparatus back panel (2) and the air cylinder.

[0028] In the preferred embodiment, the materials used to make the waist belt (1), the first waist belt (1.1), and the second waist belt (1.2) are aramid fibers.

[0031] The self-detachable waist belt provided in this embodiment of the utility model adopts both a buckle connection structure and an adsorption connection structure between the waist belt and the breathing apparatus back panel. This can improve the tightness of the breathing apparatus worn by the personnel. Since the friction provided by the adsorption connection structure is less than the weight of the breathing apparatus, the breathing apparatus can be easily and quickly detached from the personnel after the buckle is opened. This makes it convenient for firefighters to quickly carry or detach the breathing apparatus back panel and air cylinder during emergency escape.
