Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and in particular to a firefighter positioning and monitoring device. Background Technology

[0002] Firefighter positioning and monitoring devices are safety equipment used in complex environments such as fire scenes. By integrating technologies such as inertial navigation, UWB ultra-wideband, Bluetooth beacons, or multi-source data fusion, they can track and display the three-dimensional position and movement trajectory of firefighters in real time. They can work stably in dense smoke or inside buildings where GPS signals are lost. They also integrate vital sign monitoring and emergency rescue functions to help the command center understand personnel distribution, detect anomalies in a timely manner, and issue evacuation orders, effectively improving the safety and rescue efficiency of firefighting operations.

[0003] Most existing firefighter positioning and monitoring devices are divided into embedded and wearable types. Embedded firefighter positioning and monitoring devices are directly embedded in firefighter suits or firefighter boots. If they are damaged during fire rescue, they need to be removed for replacement, which is a troublesome process. Therefore, most firefighters also use wearable firefighter positioning and monitoring devices. However, existing wearable firefighter positioning and monitoring devices require straps to be tied to the firefighter's arm or waist, then the straps are tightened through a sliding structure, and finally the straps are locked with buckles. For fire rescue where every second counts, the wearing process is very troublesome. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a firefighter positioning and monitoring device that can improve the ease of wearing during use.

[0005] The objective of this invention is achieved through the following technical solution: A firefighter positioning and monitoring device includes: a housing and a securing component; The housing has an internal cavity and a first opening. The internal cavity is used to house the positioning signal module. The first opening connects the internal cavity to the outside. The binding component includes a support rod, a winding device, and a binding strap; the support rod is connected to and supported by the housing; both the winding device and the binding strap are located within the internal cavity; the winding device is connected to and supported by the support rod; the binding strap freely enters and exits the internal cavity through the first opening; the end of the binding strap is linked to the winding device so that the binding strap can extend along the first opening to bind the human body, and can be wound back by the winding device.

[0006] Furthermore, the winding device includes a winding wheel and a spiral spring. The winding wheel is located within the internal accommodating space and is used for winding the binding strap so that when the binding strap is pulled, the winding wheel rotates circumferentially around its axis. The two ends of the spiral spring are respectively connected to the support rod and the winding wheel so that the winding wheel has a tendency to wind up the binding strap.

[0007] Furthermore, the fastening member also includes a first limiting mechanism, which is connected to the housing and located within the internal cavity; the first limiting mechanism is used to restrict the winding movement of the winding device.

[0008] Furthermore, the first limiting mechanism includes a first limiting wheel and a first limiting plate. The first limiting wheel is coaxially linked with the take-up wheel so that it can rotate together with the take-up wheel. The first limiting wheel has a first ratchet tooth, and the first limiting plate has a second ratchet tooth. The first ratchet tooth and the second ratchet tooth mesh with each other to prevent the take-up wheel from winding up the binding tape. The first limiting plate has a first operating part for manual operation to engage or disengage the second ratchet tooth from the first ratchet tooth.

[0009] Furthermore, the fastening member also includes a second limiting mechanism, which is connected to the housing and located within the internal cavity; the second limiting mechanism is used to restrict the movement of the fastening strap.

[0010] Furthermore, the second limiting mechanism includes a second limiting plate and a second limiting cam. The second limiting plate is movably connected to the housing to switch between a first state and a second state: when the second limiting plate is in the first state, the movable end of the second limiting plate approaches the inner wall of the housing at the first opening, thereby cooperating with the inner wall of the housing at the first opening to clamp the binding strap; when the second limiting plate is in the second state, the movable end of the second limiting plate moves away from the inner wall of the housing at the first opening, thereby loosening the binding strap; the second limiting cam is rotatably connected to the housing so that the protrusion of the second limiting cam contacts the second limiting plate, thereby placing the second limiting plate in the first state; or the protrusion of the second limiting cam separates from the second limiting plate, thereby placing the second limiting plate in the second state; the second limiting cam has a second operating part, and the housing has a second opening for the second operating part to extend to the outside. The second operating part is used for manual operation to make the protrusion of the second limiting cam contact or separate from the second limiting plate.

[0011] Furthermore, the first operating part is provided with a clearance groove, which is used to allow the second operating part to enter the clearance groove when the protrusion of the second limiting cam separates from the second limiting plate.

[0012] Furthermore, the housing is provided with a first guide rail, which is located in the internal cavity and extends along a first horizontal direction; the second limiting plate is slidably connected to the first guide rail.

[0013] Furthermore, the second operating part is connected to a slider, the housing is provided with a second guide rail, defining a second horizontal direction that is perpendicular to the first horizontal direction, and the second guide rail extends along the second horizontal direction; the slider is slidably connected to the second guide rail.

[0014] Furthermore, at least two winding devices are provided, and the at least two winding devices are arranged at intervals along a first horizontal direction; at least two first openings are provided, and the at least two first openings are arranged at intervals along a first horizontal direction; the two ends of the binding strap are respectively passed through each of the first openings and are respectively linked to each of the winding devices.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The housing has an internal cavity and a first opening. The internal cavity is used to place the positioning signal module. As a storage space, the internal cavity not only provides space for the positioning signal module, but also protects the electronic components it contains, preventing damage to the module due to accidental collisions during rescue operations, thus improving the service life of the positioning signal module.

[0016] 2. The binding component includes a support rod, a retraction device, and a binding strap. The support rod is connected to and supported by the housing. Both the retraction device and the binding strap are located within the internal cavity. The retraction device is connected to and supported by the support rod. The binding strap freely enters and exits the internal cavity through a first opening. The end of the binding strap is linked to the retraction device, allowing the binding strap to extend along the first opening to bind the body and to be retracted by the retraction device. By housing the positioning signal module and the binding component within the same housing, the internal cavity protects the positioning module from severe impacts, high temperatures, smoke, and other harsh fire environment interference, ensuring stable positioning signals. The support rod provides stable support for the retraction device, allowing a portion of the binding strap to be stored within the housing, thus achieving a compact structure for positioning and wearing. When firefighters use it, they simply pull the binding strap out from the first opening and secure it to their arm or equipment. The retraction device then retracts the excess binding strap, ensuring the binding strap fits snugly against the body, thus improving the ease of wearing.

[0017] 3. The binding components include a support rod, a retraction device, and binding straps. The support rod is connected to and supported by the shell. Both the retraction device and the binding straps are located within the internal cavity. The retraction device is connected to and supported by the support rod. The binding straps freely enter and exit the internal cavity through a first opening. The end of the binding straps is linked to the retraction device, allowing the binding straps to extend along the first opening to secure the person and to be retracted by the retraction device. After the firefighters complete the rescue operation, the restriction on the end of the binding straps is lifted, and the retraction device automatically retracts the binding straps back into the shell, improving storage efficiency.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See Figures 1-4 A preferred embodiment of the present invention provides a firefighter positioning and monitoring device, comprising: a housing 1 and a binding member 2; The housing 1 has an internal cavity and a first opening 101. The internal cavity is used to house the positioning signal module. As a storage space, the internal cavity not only provides space for the positioning signal module but also protects the electronic components it houses, preventing damage to the module due to accidental collisions during rescue operations and extending the module's lifespan. The first opening 101 connects the internal cavity to the outside. The first opening 101 is a functional interface, primarily for the passage of the strapping strap 203, allowing it to extend from the inside of the housing 1 to the outside. The position, size, and edge design of the first opening 101 can match the width and thickness of the strapping strap 203, guiding its extension and retraction smoothly and preventing jamming. Simultaneously, the first opening 101 also indirectly serves the positioning function, acting as a signal window for the positioning signal module to transmit electromagnetic waves.

[0024] The securing component 2 includes a support rod 201, a winding device 202, and a securing strap 203. The support rod 201 is connected to and supported by the housing 1. Both the winding device 202 and the securing strap 203 are located within the internal cavity. The winding device 202 is connected to and supported by the support rod 201. The securing strap 203 freely enters and exits the internal cavity through the first opening 101. The end of the securing strap 203 is linked to the winding device 202 so that the securing strap 203 can extend along the first opening 101 to secure the human body and can be wound back by the winding device 202. By placing the positioning signal module and the securing component 2 together in the same housing 1, the internal cavity can protect the positioning module from severe impacts, high-temperature smoke, and other harsh fire environment interference, ensuring stable positioning signals. Furthermore, with the support rod 201 providing stable support for the winding device 202, a portion of the securing strap 203 is housed within the housing 1, thus achieving a compact structure for positioning and wearing. When firefighters use the strap, they simply pull the strap 203 out from the first opening 101 and secure it to their arm or equipment. The retracting device 202 then retracts the excess strap 203, ensuring it fits snugly against the body, thus improving ease of wear. One end of the strap 203 is connected to the retracting device 202, while the other end can be directly connected to the housing 1. Firefighters pull the strap 203 to create a wearing area between the two ends, and then pass their arm through this area to put the strap on. Alternatively, a dedicated area can be provided on the housing 1 for placing the other end of the strap 203. After pulling the strap 203 out from the first opening 101 and securing it to their arm or equipment, firefighters can place the strap in place to secure it. After the operation, the restriction on the strap 203 is lifted, and the retracting device 202 automatically retracts and stores the strap 203, improving storage efficiency. The winding device 202 can be a reel containing a spiral spring 2022. When the binding strap 203 is pulled out by an external force, the strap drives the reel to rotate, and at the same time, the spiral spring 2022 is gradually tightened, storing elastic potential energy. After the external force is removed, the spring releases its potential energy, driving the reel to rotate in the opposite direction, automatically retracting the binding strap onto the reel. The winding device 202 can also be a worm gear self-locking reel or a motor-driven reel.

[0025] In using this invention, the positioning signal module, the rewinding device 202, and the strapping 203 are first placed in the internal cavity of the housing 1, using the housing 1 to withstand the impact and high temperature of the fire scene. The rewinding device 202 is stably supported on the housing 1 by the support rod 201, so that the end of the strapping 203 is linked with the rewinding device 202. When using the device, the firefighter manually pulls out the strapping 203. The strapping 203 extends out of the housing 1 through the first opening 101 and wraps around the body. After the strapping 203 is positioned, the rewinding device 202 automatically tightens the strapping 203, thus completing the wearing process. This allows the firefighter to be positioned and monitored while the device is quickly secured to the firefighter.

[0026] The housing 1 has an internal cavity and a first opening 101. The internal cavity is used to house the positioning signal module. As an accommodating space, the internal cavity not only provides space for the positioning signal module but also protects the electronic components it houses, preventing damage to the module due to accidental collisions during rescue operations and improving the service life of the positioning signal module. The binding member 2 includes a support rod 201, a winding device 202, and a binding strap 203. The support rod 201 is connected to and supported by the housing 1. The winding device 202 and the binding strap 203 are both located within the internal cavity. The winding device 202 is connected to and supported by the support rod 201. The binding strap 203 freely enters and exits the internal cavity through the first opening 101. The end of the binding strap 203 is linked to the winding device 202 so that the binding strap 203 can extend along the first opening 101 to bind the human body and can be wound back by the winding device 202. By housing the positioning signal module and the securing component 2 together in the same housing 1, the internal cavity protects the positioning module from severe impacts, high temperatures, smoke, and other interference from the harsh fire environment, ensuring stable positioning signals. Furthermore, the support rod 201 provides stable support for the retractable device 202, allowing a portion of the securing strap 203 to be stored within the housing 1, thus achieving a compact structure for positioning and wearing. When firefighters use it, they simply pull the securing strap 203 out from the first opening 101 and secure it to their arm or equipment. The retractable device 202 then retracts the excess securing strap 203, ensuring it fits snugly against the body, thus completing the wearing process and improving convenience. The binding component 2 includes a support rod 201, a winding device 202, and a binding strap 203. The support rod 201 is connected to and supported by the housing 1. Both the winding device 202 and the binding strap 203 are located within the internal cavity. The winding device 202 is connected to and supported by the support rod 201. The binding strap 203 freely enters and exits the internal cavity through the first opening 101. The end of the binding strap 203 is linked to the winding device 202, allowing the binding strap 203 to extend along the first opening 101 to bind the person and to be wound back by the winding device 202. After the firefighters' rescue operation is completed, the restriction on the end of the binding strap 203 is lifted, and the winding device 202 automatically winds the binding strap 203 back into the housing 1, improving storage efficiency.

[0027] Preferably, the winding device 202 includes a winding wheel 2021 and a spiral spring 2022. The winding wheel 2021 is located in the internal accommodating space and is used for winding the binding strap 203 so that when the binding strap 203 is pulled, it drives the winding wheel 2021 to rotate circumferentially around its axis. The two ends of the spiral spring 2022 are respectively connected to the support rod 201 and the winding wheel 2021 so that the winding wheel 2021 has a tendency to wind up the binding strap 203. By employing a winding structure that combines a take-up wheel 2021 with a spiral spring 2022, when a firefighter pulls the strap 203 outward, the take-up wheel 2021 rotates accordingly and simultaneously winds the spiral spring 2022 to store energy. After the firefighter finishes wearing the strap and releases it, the spiral spring 2022 releases its elastic potential energy, causing the take-up wheel 2021 to automatically rotate back, quickly and smoothly winding the strap 203 into the housing 1 and fixing the device in the firefighter's wearing position. No additional operation is required, and the firefighter can complete the wearing process with one hand, improving the ease of installation.

[0028] Preferably, the fastening component 2 further includes a first limiting mechanism 204, which is connected to the housing 1 and located within the internal cavity. The first limiting mechanism 204 is used to restrict the winding movement of the retractable device 202. By adding a first limiting mechanism 204 connected to and built into the housing 1 to constrain the winding movement of the retractable device 202, after the firefighter pulls the fastening strap 203 out of the housing 1 and wraps it around the body, the firefighter can lock the retractable wheel 2021 through this mechanism, thus maintaining the extended length of the fastening strap 203 and blocking the continuous pull-back force of the spiral spring 2022. This prevents the fastening strap 203 from retracting when the firefighter fails to wear it with one hand, improving ease of use. After the firefighter installs the device in the required position, they only need to release the limiting mechanism to allow the spiral spring 2022 to quickly retract the fastening strap 203, improving the ease of wearing the device. The first limiting mechanism 204 can use a ratchet and pawl structure for limiting, or it can use a limiting hole in conjunction with a limiting post for limiting.

[0029] Preferably, the first limiting mechanism 204 includes a first limiting wheel 2041 and a first limiting plate 2042. The first limiting wheel 2041 is coaxially linked with the take-up wheel 2021 so that it can rotate together with the take-up wheel 2021. The first limiting wheel 2041 has a first ratchet tooth 2043, and the first limiting plate 2042 has a second ratchet tooth 2044. The first ratchet tooth 2043 and the second ratchet tooth 2044 mesh with each other to prevent the take-up wheel 2021 from winding up the binding tape 203. The first limiting plate 2042 has a first operating part 2045, which is used for manual operation to make the second ratchet tooth 2044 engage or disengage from the first ratchet tooth 2043. During the process of firefighters pulling out the strapping 203, the winding wheel 2021 rotates in the pulling direction. The gentle slope of the first ratchet tooth 2043 pushes the second ratchet tooth 2044 to lift, allowing the winding wheel 2021 to rotate. Therefore, pulling out the strapping 203 is unaffected. However, under the force of the spiral spring 2022, the strapping 203 has a tendency to automatically rewind. At this time, the first ratchet tooth 2043 and the second ratchet tooth 2044 mesh, creating mechanical interference, thereby preventing the winding wheel 2021 from reversing. The strapping 203 cannot automatically rewind, avoiding the risk of the strap retracting and loosening when it is not properly worn. After it is properly worn, the firefighter only needs to use one hand to turn the first operating part 2045 to disengage the second ratchet tooth 2044 from the first ratchet tooth 2043. The spiral spring 2022 then drives the winding wheel 2021 to retract the strapping 203. The strapping 203 can be tightened without relying on electricity, completing the wearing process and improving the convenience of wearing the strapping. The first operating unit 2045 can be a toggle slider 2054 or a lever, installed on the outside of the housing 1 or exposed through the first opening 101 on the housing 1, or controlled by a dedicated operating window or operating button.

[0030] Preferably, the securing member 2 further includes a second limiting mechanism 205, which is connected to the housing 1 and located within the internal cavity; the second limiting mechanism 205 is used to restrict the movement of the securing strap 203. When firefighters wear the device, they are prone to violent impacts, dragging, or accidental snagging of the strap by external obstacles during fire rescue operations. The second limiting mechanism 205 secures the strap 203, reducing the risk of the strap being unexpectedly stretched outwards, causing the device to loosen, and ensuring that the positioning and monitoring module can be stably and reliably fixed to the firefighter during complex rescue operations. When adjustment or release is needed, the second limiting mechanism can be released to freely adjust the strap 203, improving the reliability and convenience of operation. The second limiting mechanism 205 can adopt a clamping plate structure, relying on clamping force to tighten the strap 203; or it can adopt a wedge-shaped slider 2054 structure for locking.

[0031] Preferably, the second limiting mechanism 205 includes a second limiting plate 2051 and a second limiting cam 2052. The second limiting plate 2051 is movably connected to the housing 1 to switch between a first state and a second state: when the second limiting plate 2051 is in the first state, the movable end of the second limiting plate 2051 approaches the inner wall of the housing 1 at the first opening 101, thereby cooperating with the inner wall of the housing 1 at the first opening 101 to clamp the binding strap 203; when the second limiting plate 2051 is in the second state, the movable end of the second limiting plate 2051 moves away from the inner wall of the housing 1 at the first opening 101, thereby releasing the binding strap 203; The second limiting cam 2052 is rotatably connected to the housing 1 so that the protrusion of the second limiting cam 2052 contacts the second limiting plate 2051, thereby placing the second limiting plate 2051 in a first state; or the protrusion of the second limiting cam 2052 is separated from the second limiting plate 2051, thereby placing the second limiting plate 2051 in a second state; the second limiting cam 2052 has a second operating part 2053, and the housing 1 has a second opening 102 for the second operating part 2053 to extend to the outside. The second operating part 2053 is used for being manually operated so that the protrusion of the second limiting cam 2052 contacts or separates from the second limiting plate 2051. When a firefighter rotates the cam via the second operating part 2053, causing its protrusion to push the second limiting plate 2051 to the first state, the movable end of the limiting plate engages with the locking strap 203 on the inner wall of the housing 1. This adds a layer of rigid constraint to the locking strap 203 on top of the locking of the reel 2021, forming a double locking safety. This reduces the risk of the strap being accidentally pulled out and the device becoming loose when the firefighter is running violently in the fire scene, dragging trapped personnel, or when the equipment is hooked onto obstacles, ensuring that the positioning module is securely attached to the body during rescue. To release, simply reverse the operating part; the cam releases, the limiting plate loosens, and the retraction action is smoothly completed by the spring. Through this purely mechanical structure, firefighters can operate in dense smoke and darkness without relying on electricity, even while wearing heavy protective gloves, by touch, improving the stability of the garment and operational efficiency. The second limiting plate 2051 can be a flexible metal sheet or a rigid swing plate hinged to the housing 1. The second operating part 2053 may be a lever or knob fixed to the second limiting cam 2052, extending from the second opening 102 on the housing 1.

[0032] Preferably, the first operating part 2045 has a clearance groove 2046, which allows the second operating part 2053 to enter the clearance groove 2046 when the protrusion of the second limiting cam 2052 separates from the second limiting plate 2051. On the limited surface of the housing 1, both the first operating part 2045 and the second operating part 2053 need to be accessible to the firefighter's fingers. If they are close together and their movement trajectories intersect, without a clearance design, one operating part may obstruct the normal operation of the other, or both may protrude simultaneously, making them difficult to distinguish and operate individually when wearing gloves. The clearance groove 2046 provides a storage space for the second operating part 2053, freeing up operating space. When firefighters prepare to put on or remove the equipment, they first rotate the second operating part 2053 to its final position, causing the protrusion of the second limiting cam 2052 to separate from the second limiting plate 2051, and the fastening strap 203 to be loosened, allowing it to be pulled freely. At this point, the second operating part 2053 precisely enters the clearance groove 2046 of the first operating part 2045. By operating the second operating part 2053, the ratchet lock is released, and the device is wound up. The clearance groove 2046 fits and overlaps the operating spaces of the two operating parts, allowing both limiting mechanisms to be controlled through a single second operating part 2053, thus improving ease of use.

[0033] Preferably, the housing 1 is provided with a first guide rail 103, which is located in the internal cavity and extends along a first horizontal direction; the second limiting plate 2051 is slidably connected to the first guide rail 103. At this time, the second limiting plate 2051 is a flat plate component, and its bottom or side is provided with a sliding groove or slider 2054 that matches the first guide rail 103. When the second limiting cam 2052 rotates, the protrusion pushes the second limiting plate 2051 to slide along the guide rail toward the first opening 101, and the movable end approaches and presses against the binding strap 203; when the cam reverses, the protrusion leaves the second limiting plate 2051, and the binding strap returns to its free position. By configuring a first guide rail 103 extending along the first horizontal direction and achieving a sliding connection for the second limiting plate 2051, the guide rail constrains the movement freedom of the second limiting plate 2051, allowing it to move only in a straight line. This enables the limiting plate to be guided and translated from inside the housing 1 towards or away from the inner wall of the housing 1 at the first opening 101 under the drive of the cam. This ensures that the direction of force and the pressure position are consistent when clamping the binding strap 203, eliminating the hidden dangers of uneven clamping and weak engagement caused by the swaying or tilting of the limiting plate. The first guide rail 103 can be two parallel ridges, or it can be a dovetail groove or a T-groove.

[0034] Preferably, the second operating part 2053 is connected to a slider 2054, and the housing 1 is provided with a second guide rail 104, defining a second horizontal direction that is perpendicular to the first horizontal direction, and the second guide rail 104 extends along the second horizontal direction; the slider 2054 is slidably connected to the second guide rail 104. At this time, the second operating part 2053 is a toggle member integrally formed or fixedly connected to the slider 2054; the slider 2054 is located inside the housing 1 or passes through the opening of the housing 1, and is rigidly connected to the second operating part 2053; the slider 2054 can be block-shaped or cylindrical, and its sides or bottom are provided with guide structures that cooperate with the second guide rail 104, such as protrusions or grooves. After the firefighter releases the second limiting mechanism 205 from the restraining strap 203 and rotates the second operating part 2053 into the clearance groove 2046, the firefighter pushes the second operating part 2053. Under the constraint of the second guide rail 104 and the slider 2054, the second operating part 2053 moves along the second horizontal direction, causing the first operating part 2045 to move as well. The second ratchet tooth 2044 follows the first operating part 2045 and simultaneously separates from the first ratchet tooth 2043, giving the restraining strap 203 a tendency to rewind. By setting the second guide rail 104, the direction of movement of the second operating part 2053 is limited, allowing firefighters to operate it easily even while wearing heavy gloves, thus improving ease of use.

[0035] Preferably, at least two winding devices 202 are provided, and the at least two winding devices 202 are arranged at intervals along the first horizontal direction; at least two first openings 101 are provided, and the at least two first openings 101 are arranged at intervals along the first horizontal direction; the two ends of the fastening strap 203 are respectively threaded through each of the first openings 101 and respectively linked to each winding device 202. By using double winding devices 202 and double first openings 101 arranged at intervals along the first horizontal direction, and linking the two ends of the fastening strap 203, the fastening strap 203 can be symmetrically pulled out and retracted from both sides of the housing 1. When wearing it, the firefighter pulls out the fastening strap 203 and passes his arm through the area formed by the fastening strap 203. Waiting for the fastening strap 203 to retract completes the wearing. The fastening strap 203 fits the human body surface more closely and the pressure distribution is more even, avoiding local pressure discomfort or device deflection caused by single-point pulling, and improving the stability of the device against the body during strenuous exercise. The dual winding wheels retract synchronously and are coordinated by their respective spiral springs 2022 to ensure consistent tension and smooth movement at both ends of the strapping 203 during extension and retraction, reducing the risk of unilateral slackness or tangling. Even if one winding mechanism is temporarily obstructed by impact or contamination, the other side can still provide basic holding force, thereby improving the fault tolerance rate. Furthermore, the independent operating logic on both sides is unified, allowing firefighters to quickly lock or release the strapping with a single hand and body movement, thus improving ease of use.
