Description

Technical Field

[0001] The present invention relates to the technical field of water rescue protection equipment, in particular to a life jacket for firefighters to use in water rescue. Background Art

[0002] In the fire emergency rescue system, water rescue, as a high-risk mission scenario, places extremely high demands on the safety, functionality, and emergency response efficiency of protective equipment. As core protective equipment, firefighters' life jackets for water rescue must be designed to balance rapid buoyancy generation, wearer comfort, dynamic adjustment capabilities, and adaptability to complex environments, ensuring safety and freedom of movement for rescuers in extreme conditions such as turbulent water, low temperatures, and low light.

[0003] The tightening system of traditional life jackets is usually designed with a single tightening strap, which can only be simply fixed at the waist or chest. People of different physiques cannot quickly adjust the tightness of the life jacket, resulting in uncomfortable wearing and unbalanced force, affecting the firefighters' flexibility and rescue efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a life jacket for firefighters to use in water rescue, which solves the problem that the traditional life jacket cannot be tightened evenly on the shoulders, waist and hips.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a life jacket for firefighters' water rescue, comprising a life jacket body, a tightening assembly fixedly connected to the opening of the life jacket body, a sealing ring is provided on the outside of the life jacket body, a support ring is fixedly connected to the outside of the lower side of the life jacket body, a placement assembly is slidably connected to the outer wall of the support ring, a plurality of inflatable air bags are provided inside the life jacket body, a micro air pump is provided inside the inflatable air bags, an air inlet of the micro air pump is provided inside the life jacket body, the sealing ring is provided at the air inlet of the micro air pump, a tightening rope 1 is provided inside the upper side of the life jacket body, a tightening rope 2 is fixedly connected to the front bottom end of the tightening rope 1, a mounting post 1 is fixedly connected to the outer wall of the tightening rope 2, a tightening rope 3 is provided inside the lower side of the life jacket body, and a mounting post 2 is fixedly connected to the outer wall of the tightening rope 3.

[0006] By adopting the above technical solution, when the grip of the tightening assembly is rotated, it drives the synchronous rotation of the first and second rotating columns, triggering the micro air pump to start, rapidly inflating the multiple inflatable airbags, causing the life jacket to expand rapidly and generate buoyancy. After inflation is completed, the one-way meshing structure of the ratchet and ratchet teeth automatically locks to prevent the life jacket from loosening. At the same time, the tightening ropes one, two, and three, through the linkage of the mounting columns one and two, act on the upper, middle, and lower parts of the life jacket respectively, evenly tightening each key part, ensuring that the life jacket fits the body closely during water impact or dynamic rescue maneuvers, reducing local shaking and pressure, allowing firefighters of different physiques to quickly adjust to a comfortable and balanced state of force, and improving mobility.

[0007] Preferably, the tightening assembly includes a shell, the outer wall of the shell is fixedly connected to the opening of the life jacket body, the interior of the shell is rotatably connected to a rotating column 1, one side outer wall of the rotating column 1 is fixedly connected to a handle 1, and the other side outer wall of the rotating column 1 is fixedly connected to a rotating column 2.

[0008] Preferably, the tightening assembly further includes a contact block, the outer wall of the contact block is fixedly connected to the outer wall of the rotating column 2, a detector is provided inside the shell, the detector is used to detect the contact block, and the contact block is electrically connected to the micro air pump.

[0009] Preferably, the outer wall of the rotating column is fixedly connected to a ratchet, the tooth end of the ratchet is meshedly connected to a ratchet, the outer wall of the ratchet rotates on the outer wall of the shell, and the lower outer wall of the ratchet is fixedly connected to a paddle.

[0010] Preferably, the placement component includes a storage bag, the upper surface of the storage bag is rotatably connected to a cover plate, the outer wall of the storage bag is fixedly connected to handle 2, the outer wall at the rear end of the storage bag is fixedly connected to limit plate 1 and limit plate 2, and the limit plate 1 and limit plate 2 are relatively slidably connected to the outer wall of the support ring.

[0011] Preferably, a flow groove is provided at the bottom end of the storage bag, and the flow groove has a mesh structure for draining water and preventing accumulation of debris.

[0012] Preferably, the outer surface of the life jacket body is coated with a reflective coating, and the reflective coating covers the shoulder and back areas of the life jacket body.

[0013] Preferably, a filter is provided at the air inlet of the micro air pump.

[0014] Preferably, a first mounting groove is provided inside the shell, and a second mounting groove is provided inside the first rotating column.

[0015] Preferably, the second tightening rope is located in the middle interior of the life jacket body, and the first and second mounting posts are arranged inside the life jacket body.

[0016] Working Principle: After donning the life jacket, a firefighter opens the sealing ring at the air inlet of the micro-pump. By rotating the first handle of the tightening assembly, the first and second rotating columns rotate synchronously. A contact block on the outer wall of the second rotating column moves with the rotation. When a detector detects that the contact block has reached a preset angle, it immediately sends a start signal to the micro-pump, which draws air and rapidly inflates multiple inflatable bladders distributed throughout the life jacket. During inflation, the bladders expand, generating buoyancy.

[0017] After inflation is completed, the firefighter continues to rotate handle one, and a one-way lock is achieved through the engagement of the ratchet and the ratchet teeth to prevent the life jacket from loosening. At this time, tightening rope one, tightening rope two, and tightening rope three are linked through mounting column one and mounting column two to evenly tighten the upper, middle, and lower parts of the life jacket to ensure that it fits the body and the force is balanced. If the tightness needs to be adjusted, the paddle can be turned to disengage the ratchet and the ratchet wheel, and the rope tension can be released by rotating handle one in the opposite direction to achieve quick adjustment.

[0018] The storage bag containing the components slides horizontally along the outer wall of the support ring via stoppers 1 and 2, allowing firefighters to adjust the tool position according to mission requirements. A mesh flow groove at the bottom of the bag allows accumulated water to drain naturally while preventing the entry of debris such as mud and sand. The cover is double-sealed with a magnetic fastening device and waterproof sealing strip to ensure the tools inside are dry. Grip 2 allows for easy one-handed opening and closing.

[0019] The present invention provides a life jacket for firefighters to use in water rescue operations. It has the following beneficial effects:

[0020] 1. The first, second, and third tightening ropes inside the life jacket of the present invention are linked together through the mounting post, acting on the upper, middle, and lower parts respectively, achieving uniform tightening of the shoulders, waist, and hips, ensuring force balance under the impact of water flow, avoiding local compression or shaking, improving wearing comfort and movement flexibility, and solving the problem of uneven fit of a single tightening strap in traditional life jackets. It can adapt to the dynamic rescue actions of firefighters of different body shapes.

[0021] 2. The present invention triggers the micro air pump by rotating the handle to start, quickly inflating multiple distributed inflatable airbags, significantly shortening the inflation time and ensuring that firefighters quickly obtain buoyancy support. At the same time, the one-way meshing structure of the ratchet and ratchet teeth automatically locks the tightening rope after inflation to prevent the life jacket from loosening. When adjustment is needed, the lock can be released by turning the paddle and the tension can be released by rotating in the opposite direction, taking into account both safety and wearing flexibility.

[0022] 3. The storage bag for the components of the present invention slides on the support ring via a limit plate, allowing the tool position to be adjusted as needed. The mesh flow groove at the bottom automatically drains water and blocks debris. The cover is doubly sealed with a magnetic buckle and a waterproof sealing strip to ensure that the tools are dry, realizing the integration of tool storage and life jacket structure. At the same time, the reflective coating on the shoulder and back areas improves visibility in low-light environments, enhancing the safety and durability of the life jacket in extreme water environments.

[0031] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a life jacket for firefighters' water rescue, including a life jacket body 1, a tightening component 2 is fixedly connected to the opening of the life jacket body 1, a sealing ring 3 is provided on the outside of the life jacket body 1, a support ring 4 is fixedly connected to the outside of the lower side of the life jacket body 1, and a placement component 5 is slidably connected to the outer wall of the support ring 4, a plurality of inflatable air bags 6 are provided inside the life jacket body 1, a micro air pump 7 is provided inside the inflatable air bag 6, an air inlet of the micro air pump 7 is provided inside the life jacket body 1, and the sealing ring 3 is provided at the air inlet of the micro air pump 7, a tightening rope 1 8 is provided inside the upper side of the life jacket body 1, a tightening rope 2 9 is fixedly connected to the front bottom end of the tightening rope 1 8, and a mounting post 10 is fixedly connected to the outer wall of the tightening rope 2 9, a tightening rope 3 11 is provided inside the lower side of the life jacket body 1, and a mounting post 2 12 is fixedly connected to the outer wall of the tightening rope 3 11.

[0033] Specifically, after the firefighter puts on the life jacket body 1, he installs the mounting post 10 and the mounting post 2 12 inside the tightening assembly 2. The mounting post 10 and the mounting post 2 12 are made of magnets. The sealing ring 3 is opened from the air inlet of the micro air pump 7. By rotating the tightening assembly 2, a start signal is sent to the micro air pump 7. The micro air pump 7 inhales air and quickly inflates the multiple inflatable air bags 6 distributed in the life jacket body 1. During the inflation process, the airbag expands to generate buoyancy. After the inflation is completed, the firefighter continues to rotate the handle 1 23 to achieve one-way locking through the engagement of the ratchet 13 and the ratchet 14 to prevent the life jacket from loosening. At this time, the tightening rope 1 8, the tightening rope 2 9, and the tightening rope 3 11 are linked through the mounting column 1 10 and the mounting column 2 12 to evenly tighten the upper, middle and lower parts of the life jacket to ensure that it fits the body and the force is balanced. If the tightness needs to be adjusted, the paddle 15 can be turned to disengage the ratchet 14 and the ratchet 13, and the rope tension can be released by rotating the handle 1 23 in the opposite direction to achieve quick adjustment. The placement component 5 makes it convenient for firefighters to adjust the tool position according to task requirements.

[0034] Please see the attached Figure 3 -Attached Figure 5 The tightening assembly 2 includes a shell 21, the outer wall of the shell 21 is fixedly connected to the opening of the life jacket body 1, and the interior of the shell 21 is rotatably connected to a rotating column 22, one side outer wall of the rotating column 22 is fixedly connected to a handle 23, and the other side outer wall of the rotating column 22 is fixedly connected to a rotating column 24; the tightening assembly 2 also includes a contact block 25, the outer wall of the contact block 25 is fixedly connected to the outer wall of the rotating column 24, and a detector 26 is provided inside the shell 21, the detector 26 is used to detect the contact block 25, and the contact block 25 is electrically connected to the micro air pump 7; the interior of the shell 21 is provided with a mounting groove 27, and the interior of the rotating column 22 is provided with a mounting groove 28.

[0035] Specifically, when the mounting column 10 and the mounting column 2 12 are installed inside the mounting groove 2 28 through the mounting groove 1 27, the handle 1 23 of the tightening assembly 2 is rotated to drive the rotating column 1 22 and the rotating column 2 24 to rotate synchronously, and the contact block 25 on the outer wall of the rotating column 2 24 is displaced with the rotation. When the detector 26 detects that the contact block 25 reaches a preset angle, it immediately sends a start signal to the micro air pump 7. The micro air pump 7 inhales air and quickly inflates multiple inflatable airbags 6 distributed in the life jacket body 1. During the inflation process, the airbags expand to generate buoyancy. The detector 26 is a Hall effect sensor and the contact block 25 is a magnet. The inflation time can be set inside the micro air pump 7, and different inflation times are set according to the size of the inflatable airbag 6.

[0036] Please see the attached Figure 4 and attached Figure 5 The outer wall of the rotating column 22 is fixedly connected to the ratchet 13, the tooth end of the ratchet 13 is meshed with the ratchet 14, the outer wall of the ratchet 14 rotates on the outer wall of the shell 21, and the lower outer wall of the ratchet 14 is fixedly connected to the paddle 15.

[0037] Specifically, when the firefighter rotates the handle 23 to drive the rotating column 22 to rotate clockwise, the ratchet 13 fixed on its outer wall rotates synchronously. At this time, the ratchet 14 slides on the tooth back of the ratchet 13, and the ratchet 14 will not hinder the forward rotation of the rotating column 22. When the inflation is completed and the life jacket needs to be fixed, the handle 23 is stopped from being rotated, and the ratchet 14 will be stuck in the tooth groove of the ratchet 13, forming a one-way locking structure, which effectively prevents the rotating column 22 from reversing counterclockwise, thereby ensuring the stability of the tightening state of the tightening rope and preventing the life jacket from loosening due to water impact or body movements during water rescue.

[0038] When the tightness of the life jacket needs to be adjusted, the firefighter only needs to use his finger to move the paddle 15 to drive the ratchet 14 to rotate, so that it disengages from the tooth groove of the ratchet wheel 13. At this time, the handle 1 23 can be rotated in the opposite direction to release the tension of the tightening rope, thereby achieving quick adjustment.

[0039] Please see the attached Figure 6 and attached Figure 7 The placement component 5 includes a storage bag 51, the upper surface of the storage bag 51 is rotatably connected to a cover plate 52, the outer wall of the storage bag 51 is fixedly connected to a handle 2 53, the outer wall of the rear end of the storage bag 51 is fixedly connected to a limit plate 1 54 and a limit plate 2 55, and the limit plate 1 54 and the limit plate 2 55 are relatively slidably connected to the outer wall of the support ring 4; a flow groove 56 is opened at the bottom end of the storage bag 51, and the flow groove 56 has a mesh structure for drainage and preventing accumulation of debris.

[0040] Specifically, the placement component 5 includes a storage bag 51, which is mainly used to place small tools, spare items, etc. that firefighters may use during water rescue. When firefighters need to use the items in the storage bag 51, they open the storage bag 51 by rotating the cover 52, and then, according to their own operating habits, hold the handle 2 53 to slide the placement component 5 along the support ring 4 to a position that is easy to operate. During the rescue process, once water enters the storage bag 51, the water will naturally flow out through the flow groove 56, while the debris will be blocked in the storage bag 51 or intercepted by the mesh structure to prevent it from clogging the drainage channel. When the storage bag 51 is no longer needed, the cover 52 is rotated closed to prevent items from falling. At the same time, the placement component 5 can be fixed to a suitable position on the support ring 4 as needed without affecting other rescue operations of the firefighters.

[0041] Please see the attached Figure 1 -Attached Figure 3 The outer surface of the life jacket body 1 is coated with a reflective coating, which covers the shoulder and back areas of the life jacket body 1; a filter is provided at the air inlet of the micro air pump 7; the tightening rope 2 9 is located in the middle interior of the life jacket body 1, and the mounting post 10 and the mounting post 2 12 are provided inside the life jacket body 1.

[0042] Specifically, during the day, the reflective coating reflects light, making firefighters wearing life jackets more visible, allowing teammates to quickly identify their positions in complex rescue environments and better coordinate rescue operations. At night or in dimly lit environments, the reflective coating is even more effective. When exposed to light, such as searchlights or flashlights from rescue vessels, the reflective coating reflects the light, creating a strong reflective effect that can be clearly detected from a distance, improving the identification and visibility of firefighters in dark waters.

[0043] The micro air pump 7 is responsible for sucking in external air and compressing it into the air bag of the life jacket. The filter screen at the air inlet can effectively filter out impurities, ensuring that the air entering the micro air pump 7 is clean, so that the air pump can work stably and efficiently, and ensure that the life jacket can be inflated quickly and reliably when needed, providing the necessary buoyancy support for firefighters. The tightening rope 2 9, the mounting column 1 10 and the mounting column 2 12 together constitute the tightening adjustment system of the life jacket. The tightness of the life jacket can be adjusted by rotating the tightening rope 2 9 by rotating the rotating column 1 22.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
