Description

Technical Field

[0001] The utility model belongs to the technical field of offshore operation carrying tools and relates to a life jacket. Background Art

[0002] Offshore operations are characterized by many risk factors, great harm caused, and difficulty in calling for rescue. Among existing offshore operation equipment, an offshore operation vest (i.e., life jacket) that can generate buoyancy is an important piece of equipment. These life jackets can provide necessary buoyancy in case of danger, helping personnel stay on the water surface and wait for rescue. However, there are some limitations in the inflation method of existing life jackets that can generate buoyancy. The existing inflation methods mainly include the user directly blowing air through the inflation port or pulling the inflation device to inflate. For example, in the Chinese patent with the publication number CN113854667A, its air supply system includes an air supply pipe communicated with the airbag and an inflation and exhaust nozzle connected to the end of the air supply pipe. The inflation and exhaust nozzle has an inflation end for connecting to a gas source. The inflation and exhaust nozzle also has a gas supply end for biting and breathing with the human mouth. This inflation method cannot meet the requirements in some emergency situations in terms of inflation speed. In a very short period of time, if the life jacket cannot be quickly inflated and generate sufficient buoyancy, personnel may face the risk of drowning. Summary of the Utility Model

[0011] Preferably, two ventilation ducts are symmetrically arranged on the air chamber, and both of the two ventilation ducts are connected to the airbag.

[0012] Preferably, the telescopic assembly is a spring or a rubber block.

[0013] Preferably, the distance between the spike end of the puncturing member and the baffle member is 2-3 cm.

[0014] Preferably, the baffle member is an airtight film.

[0015] Preferably, the inflation assembly is arranged on the left side or the right side of the waist of the life jacket main body.

[0016] Preferably, a positioning assembly is further arranged on the life jacket main body.

[0017] Compared with the prior art, the utility model has the following beneficial technical effects:

[0018] The utility model discloses a life jacket. In this life jacket, the life jacket main body is the basic structure of the whole life jacket, providing buoyancy support for the wearer. The inflation assembly is a key part of the life jacket, which includes an air chamber and a movable puncturing member. The air chamber is pre-filled with compressed gas or contains a gas generating agent, and can quickly generate gas when needed. The puncturing member is a movable part, and its spike end faces the baffle member. This design allows the user to puncture the baffle member by pushing the puncturing member, thereby realizing the connection between the air chamber and the airbag. The baffle member is located in the air chamber and plays a role of sealing and isolating. In the normal use state, it prevents the gas in the air chamber from leaking into the airbag. When the puncturing member is pushed and punctures the baffle member, the seal between the air chamber and the airbag is broken, and the gas can quickly flow into the airbag. The airbag is the main buoyancy source of the life jacket. When the inflation assembly is activated and the gas enters the airbag, the airbag will quickly expand to provide sufficient buoyancy for the wearer. When using this life jacket, pushing the puncturing member towards the baffle member can realize the connection between the inflation assembly and the airbag, so that the gas in the air chamber can quickly enter the airbag, effectively realizing the rapid inflation of the airbag. The core advantage of this utility model is that it is easy to operate and can be quickly inflated. The user only needs to push the puncturing member to achieve rapid inflation, without complex steps or tools, providing effective safety protection for users.

[0019] Furthermore, the puncturing member includes a pressing portion, a telescopic component, and a spiking portion that are connected and arranged in sequence. The spiking end of the spiking portion extends towards the partition member. The design of the pressing portion enables the user to operate the puncturing member through a simple pressing action. This intuitive operation method reduces the usage difficulty, enabling the user to quickly and accurately complete the inflation operation even in an emergency. As the part connecting the pressing portion and the spiking portion, the telescopic component can ensure that during the pressing process, the spiking portion can stab towards the partition member stably and accurately. This structural stability is crucial for ensuring the inflation effect. The spiking end of the spiking portion extends towards the partition member, ensuring that during the inflation process, gas can quickly and effectively enter the airbag from the air chamber. At the same time, due to the design of the spiking portion, the possibility of accidentally touching or puncturing the partition member during normal use is also avoided, thereby improving the safety of the life jacket. This puncturing member with such a structural design has high reliability. In an emergency, the user can quickly complete the inflation operation by pressing the pressing portion, ensuring that the life jacket can promptly provide buoyancy support for the wearer. In addition, the design of the telescopic component and the spiking portion also ensures the stability and reliability of the inflation process.

[0020] Furthermore, the air chamber is provided with a through hole, and the spiking portion is slidably arranged at the through hole. When the spiking portion is pressed down and slides at the through hole, the through hole is caused to open, and at the same time, the overflowing gas can enter the airbag through the through hole, improving the convenience of using the device.

[0021] Furthermore, the air chamber is also provided with a ventilation duct. One end of the ventilation duct is connected to the through hole, and the other end is connected to the airbag. The setting of the ventilation duct makes the replacement of the inflation component more convenient.

[0022] Furthermore, the telescopic component is a spring or a rubber block. This type of telescopic component has good elasticity. When the pressing portion is pressed, the telescopic component can quickly respond and push the spiking portion towards the partition member, thereby achieving rapid inflation. This rapid response is crucial for quickly providing buoyancy in an emergency. Springs and rubber blocks have excellent reliability and durability. During the use of the life jacket, the telescopic component can maintain stable performance, ensuring normal operation when needed. In addition, springs and rubber blocks are usually relatively compact and occupy little space. This helps to achieve a compact layout inside the life jacket while maintaining sufficient buoyancy support. The compact design also makes the life jacket lighter, facilitating carrying and wearing. Springs and rubber blocks will not be accidentally triggered or fail during normal use. In the case where inflation is not required, the telescopic component can maintain a stable state, avoiding misoperation or accidental inflation. In addition, if the telescopic component is damaged or fails, it can be easily repaired or replaced. Springs and rubber blocks are both common materials, easy to obtain and replace, which helps to reduce the maintenance cost of the life jacket and improve its usability.

[0023] Furthermore, the distance between the spiked end of the puncturing member and the partitioning member is 2 - 3 cm, such that the puncturing member can puncture the partitioning member without excessive thrust, and the convenience of use is higher.

[0024] Furthermore, the partitioning member is an airtight film, which can effectively prevent gas from passing through when it is not required to flow, ensuring that the gas can flow along the designed path when needed, thus guaranteeing the accuracy and reliability of the inflation process. The film material usually has a relatively light weight, which is very important for equipment such as life jackets that need to reduce the burden on the wearer. At the same time, the film material also has a certain degree of flexibility, enabling it to adapt to the requirements of different shapes and surfaces, making it easier for the partitioning member to fit with the air chamber or other components. High-quality airtight films can resist the influence of various climate conditions, including high temperature, low temperature, humidity, and dryness. This weather resistance enables the partitioning member to maintain stable performance in a variety of environments, ensuring the long-term effective use of life jackets or other equipment. The film material is easy to process and form, and can be cut or pasted according to needs. This makes the partitioning member more flexible in the manufacturing process and can be customized according to different designs and requirements. At the same time, the flexibility of the film material also makes the installation process simpler. Compared with other airtight materials, the film material usually has a lower cost, reducing the manufacturing cost of life jackets or other equipment. At the same time, the durability of the film material also reduces the cost of later maintenance and replacement.

[0025] Furthermore, the inflation component is arranged on the left or right side of the waist of the life jacket main body, enabling the wearer to quickly and conveniently find and operate the inflation component in case of an emergency. This design conforms to ergonomics, making it relatively easy to operate with either the right hand or the left hand, improving the convenience and efficiency of operation. The waist position has less impact on the freedom of movement compared to other body parts. By arranging the inflation component here, the influence of the inflation component on the normal activities of the wearer can be reduced, enabling the wearer to maintain a high degree of freedom of movement before and after inflation. Arranging the inflation component at the waist can reduce the risk of accidental inflation caused by accidental touch or other non-intentional actions. Especially in water or a tense environment, misoperation may cause unnecessary trouble or danger to the wearer. Arranging the inflation component on the left or right side of the waist helps to achieve a relatively balanced buoyancy distribution after inflation. This distribution can reduce the possibility of the wearer rolling or tilting in the water, improving the stability and safety of the wearer. The waist position is relatively fixed, and the difference in the waist position of people with different body types is relatively small. Therefore, arranging the inflation component at the waist can meet the needs of wearers with different body types, ensuring the versatility and applicability of the inflation component. In addition, the waist position is subject to less impact and pressure compared to the chest or abdomen. By arranging the inflation component here, the discomfort or injury caused to the human body during inflation can be reduced, improving the comfort and safety of the wearer.

[0026] Furthermore, a positioning component is also provided on the life jacket main body. This positioning component can accurately transmit the position information of the wearer to the search and rescue personnel, enabling the search and rescue personnel to quickly locate the person in distress, thus greatly improving the efficiency and accuracy of the rescue. In addition, the positioning component can also increase the visibility of the wearer in complex environments (such as at night, in fog, on the water surface, etc.) by emitting flashes or sounds. This helps the search and rescue personnel to find the person in distress faster, especially in cases with poor visibility. The positioning component can update the position information of the wearer in real time, ensuring that the search and rescue personnel always know the latest position of the person in distress. This is particularly important for a dynamically changing rescue environment, as natural factors such as water flow and wind direction may cause the position of the person in distress to change. Through the position information provided by the positioning component, the search and rescue personnel can more accurately plan the rescue route, avoid blind searching, and thus improve the rescue success rate. In addition, the real-time update of the position information also helps the search and rescue personnel to judge the survival status of the person in distress, providing a reference for rescue decisions.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0041] The following further describes the present utility model in detail with reference to the accompanying drawings:

[0042] As Figures 1 - 2As shown in the figure, the utility model discloses a life jacket, which comprises a life jacket main body 1; an inflation assembly 2 and an airbag 3 are arranged on the life jacket main body 1; the inflation assembly 2 comprises an air chamber 21; a partition member 4 is arranged in the air chamber 21; a movable puncturing member 22 is arranged at the opening of the air chamber 21; the pointed end of the puncturing member 22 extends towards the partition member 4; the opening of the air chamber 21 is communicated with the airbag 3.

[0043] The life jacket main body 1 is the basic structure of the life jacket, providing buoyancy support for the wearer to ensure that the head and mouth and nose can be kept above the water surface in case of emergency and prevent drowning. The life jacket main body 1 is usually made of nylon fabric or waterproof materials such as neoprene to ensure durability and waterproof performance in water. The inflation assembly 2 is a key part of the life jacket, which includes an air chamber 21 and a movable puncturing member 22. In case of emergency, the puncturing member 22 will puncture the partition member 4, so that the gas in the air chamber 21 quickly fills the airbag 3, providing sufficient buoyancy for the wearer. The air chamber 21 and the puncturing member 22 of the inflation assembly 2 are usually made of waterproof materials and high-strength materials to ensure reliability and durability in harsh environments. The pointed end of the puncturing member 22 needs to have sufficient hardness and sharpness to be able to puncture the partition member 4. The airbag 3 is the buoyancy source of the life jacket. When the inflation assembly 2 is activated, the gas in the air chamber 21 quickly fills the airbag 3, causing the life jacket to expand and providing sufficient buoyancy for the wearer. The airbag 3 is usually made of lightweight, soft and durable materials such as nylon cloth or neoprene. These materials have good waterproofness and durability, ensuring that the airbag 3 can maintain its buoyancy performance during long-term use. The partition member 4 is located inside the air chamber 21 and is used to keep the air chamber 21 sealed when the life jacket is not inflated. The partition member 4 is usually made of an airtight film, which has good airtightness and waterproofness, ensuring that the air chamber 21 is sealed in the non-inflated state. At the same time, the partition member 4 also needs to have a certain toughness and strength so that it can quickly break and release gas when punctured.

[0044] Preferably, as Figure 2As shown, in one embodiment, the puncturing member 22 includes a pressing portion 221, a telescopic assembly 222, and a spike portion 223 that are connected and arranged in sequence. The spike end of the spike portion 223 extends towards the partition member 4. The pressing portion 221 is the direct part operated by the user. By pressing this part, the user can activate the entire puncturing member 22. The pressing action is converted into power through the telescopic assembly 222, and finally the spike portion 223 punctures the partition member 4. The pressing portion 221 needs to have a certain hardness to ensure that sufficient force can be generated when the user presses it. At the same time, for comfortable operation and anti-slip, its surface may adopt an anti-slip material or coating. The materials include metal, hard plastic, or plastic with an anti-slip coating. When the pressing portion 221 is pressed, the telescopic assembly 222 will contract and push the spike portion 223 to move forward. It plays a role in transmitting force and converting motion. The telescopic assembly 222 has sufficient elasticity and durability to support repeated operations. The material is spring steel, stainless steel, or other highly elastic metals or alloys. The spike portion 223 is the final executing part of the puncturing member 22, and its spike end is responsible for puncturing the partition member 4. The spike portion 223 needs to have sufficient hardness and sharpness to ensure that it can quickly and effectively puncture the partition member 4. The spike portion 223 is made of hard metal, such as stainless steel, carbon steel, etc. These materials have good hardness and wear resistance, and can ensure that the spike portion 223 maintains its sharpness and reliability during long-term use.

[0045] In one embodiment, through holes are provided on the air chamber 21, and the spike portion 223 is slidably arranged at the through holes. An air vent conduit 5 is also provided on the air chamber 21. One end of the air vent conduit 5 is connected to the through hole, and the other end is connected to the airbag 3.

[0046] In a preferred embodiment, the telescopic assembly 222 is a spring or a rubber block. More preferably, as Figure 2 shown, it is a spring. Springs are usually made of steel or stainless steel because these two materials have sufficient elasticity, strength, and durability. The rubber block uses highly elastic rubber, which has good elasticity and resilience, and can resist a certain degree of compression and stretching at the same time.

[0047] Further preferably, the distance between the spike end of the puncturing member 22 and the partition member 4 is 2 - 3 cm. The partition member 4 is an airtight film. As Figure 3 shown, the airbag 3 is arranged around the bottom end of the life jacket main body 1.

[0048] The inflation assembly 2 is arranged on the left side or the right side of the waist of the life jacket main body 1, as Figure 1 and Figure 4As shown, an inflatable component fixing member 7 is further provided on the life jacket main body 1. The inflatable component fixing member 7 is arranged on the left side or the right side of the waist of the life jacket main body 1. The inflatable component fixing member 7 includes a first fixing portion 71 and a second fixing portion 72. Both ends of the first fixing portion 71 are respectively connected to the front flap and the rear flap of the life jacket main body 1 to form a receiving cavity 73. The receiving cavity 73 is used for placing the inflatable component 2. The second fixing portion 72 is a telescopic component. Preferably, it can be an elastic member, which can make the inflatable component 2 more stable when placed inside the receiving cavity 73. The first fixing portion 71 and the second fixing portion 72 jointly fix the inflatable component 2.

[0049] As Figure 1 described above, a positioning component 6 is further provided on the life jacket main body 1. Adjusting shoulder straps 8 are arranged at both the left shoulder and the right shoulder of the life jacket main body 1. On the one hand, the adjusting shoulder straps 8 are convenient for adjusting according to the user's body type, and on the other hand, they can be used for quick disassembly.

[0050] As Figure 5 shown, an adjusting buckle 9 is further provided on the waist side of the life jacket main body 1. The adjusting buckle 9 is arranged on the side opposite to the inflatable component fixing member 7. Similar to the adjusting shoulder strap 8, on the one hand, the adjusting buckle 9 is convenient for adjusting according to the user's body type, and on the other hand, it can be used for quick disassembly.

[0051] As Figure 1 shown, a name tag 10, a magic tape 11, a tourniquet storage portion 12, a positioning component embedding portion 13, and a first aid item storage portion 14 are further provided on the front flap of the life jacket main body 1. An airbag fixing member 15 is further provided at the bottom end of the life jacket main body 1. Among them, the name tag 10 is a personal identifier, the magic tape 11 is a military-civilian dual-use adjustable device, and the tourniquet storage portion 12, the positioning component embedding portion 13, and the first aid item storage portion 14 are structural diagrams for reasonably arranging personal distress first aid and convenient search and rescue equipment.

[0052] In addition, as Figure 6 shown, an embedding material 16 is provided in the positioning component embedding portion 13 to realize the fixation of the positioning component 6. The controllable inflatable device composed of the inflatable component 2, the airbag 3, and the airbag fixing member 15 is convenient for the person in distress to quickly float on the sea surface and stabilize the center of gravity after falling into the water, which is convenient for the person in distress to carry out self-rescue in time and for the search and rescue work of the rescue team.

[0053] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
