Description

Technical Field

[0001] The present invention relates to the technical field of life-saving belts, and more specifically, to a water-movable life-saving belt. Background Art

[0002] A water life-saving belt, also known as a swimming anti-drowning belt or a life-saving belt, is a device that can maintain buoyancy on the water surface. Its main purpose is to provide life-saving protection when accidentally drowning during swimming or other water activities, help the drowning person conserve energy, and avoid drowning accidents. The water life-saving belt is applicable to various water activity places, such as swimming pools, beaches, rivers and lakes, etc. At the same time, it is also applicable to some special industries, such as island tourism, offshore construction and other fields. In these environments, the water life-saving belt can be used as an important safety measure to reduce the risk of drowning.

[0003] Among them, the patent with the patent application number CN201810047799.8 discloses a 3D life-saving belt, including a base cloth at the bottom layer, a top layer and an intermediate layer arranged between the two. The two free ends of the base cloth are connected with adjustable-length adjustment belts. A connection buckle for buckling the belt is arranged on the adjustment belt. An air cylinder and an expansion airbag are arranged on the base cloth. An inflation switch for controlling the connection between the air cylinder and the expansion airbag is arranged on the air cylinder. The expansion airbag is provided with a one-way air blowing pipe, and an air pipe cover is arranged on the air blowing pipe. The outer surface of the top layer is printed with a fluorescent life-saving logo;

[0004] When this structure is in use, it is convenient to carry when the belt is not inflated and will not affect water activities. In an emergency, the air storage tank is opened, and the expansion airbag can be quickly filled. However, its inflation depends on the steel gas cylinder carried by itself, which is pre-filled with high-pressure air inside. When in use, the inflation switch is opened, and the airbag expands to generate buoyancy. However, the inflation speed when the inflation switch is opened is relatively low. At the same time, when the user drowns, they are usually panicked and prone to misoperation and unable to open the inflation switch, resulting in drowning and unable to achieve the function of self-rescue. Therefore, a water-movable life-saving belt is provided. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-movable life-saving belt, aiming to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A water-movable life-saving belt, including a nylon support frame for support, and a life-saving component is arranged on the nylon support frame;

[0007] The life-saving component includes an airbag ignition and inflation device disposed at the top of the nylon support frame and used to force the inflation of the enhanced life-saving airbag main body. Two connecting bars are provided at the bottom of the airbag ignition and inflation device, and a pressure water level sensor for detecting water pressure at different depths is provided at the bottom of each connecting bar. A plurality of elastic restraint bands for limiting are stacked on each of the two connecting bars. A controller is provided on the nylon support frame. An outer support frame for support is provided on one side of the surface of the nylon support frame, and an alarm for alarming is provided on the outer support frame;

[0008] Reinforcing support restraint arm plates with adjustable angles are provided on both sides of the nylon support frame. A limiting arc plate for support is provided on one side of each reinforcing support restraint arm plate. An installation cavity groove for installing the enhanced life-saving airbag main body is provided on each of the two limiting arc plates. An elastic blocking member for protection is provided on the side of the reinforcing support restraint arm plate away from the limiting arc plate. A support shaft for support is provided at one end of the reinforcing support restraint arm plate. A shaft pin plate is provided on the support shaft. The airbag ignition and inflation device is communicated with the enhanced life-saving airbag main body through a reinforced elastic conduit, and a one-way valve is provided at the connection between the reinforced elastic conduit and the enhanced life-saving airbag main body;

[0009] It can be seen that in the above technical solution, the user puts the legs into each elastic restraint band, so that the pressure water level sensor can be located at the ankle, and the connecting bar can be tied to the leg, which is easy to wear the device. When the pressure water level sensor detects a pressure change exceeding the preset threshold, it will send a signal to the controller. The controller signals and determines whether it is necessary to trigger the airbag ignition and inflation device of the enhanced life-saving airbag main body. If the controller determines that it is necessary to trigger the enhanced life-saving airbag main body, it sends an instruction to the airbag ignition and inflation device to make it ignite and inflate, so that the enhanced life-saving airbag main body quickly fills with gas and bounces open, enabling the user to float on the water surface, effectively realizing the function of active life-saving. And when the device is worn on the body, the elastic blocking member contacts the user's body, improving the comfort of wearing the device. The setting of the limiting arc plate and the installation cavity groove facilitates the installation of the enhanced life-saving airbag main body on both sides of the device, and the limiting arc plate facilitates the storage of the enhanced life-saving airbag main body after deflation;

[0010] A dislocation opening is provided on the nylon support frame and between the two reinforcing support restraint arm plates. An electric push rod for driving is provided in the dislocation opening. A connecting column is provided at one end of the electric push rod. Two shaft pin pull rods are rotatably connected to the connecting column. A limiting column is provided at the output end of the electric push rod. The end parts of the connecting column, the shaft pin pull rods and the limiting column respectively extend to the shaft pin plates to which the two support shafts belong and are rotatably connected to the shaft pin plates. Central holes for rotatably connecting with the reinforcing support restraint arm plates are provided at the top and bottom of the inner cavity of the dislocation opening on the nylon support frame;

[0011] It can be seen that in the above technical solution, the output end of the electric push rod extends to drive the displacement of the limit post. When the limit post displaces, the reinforced support restraint arm plate can rotate along the axis point of the connection between the reinforced support restraint arm plate and the central hole through the pin plate, and then the two reinforced support restraint arm plates are clamped together, making it easy to wear the device on the waist;

[0012] Technical effects and advantages of the present invention:

[0013] 1. In the present invention, the output end of the electric push rod extends to drive the displacement of the limit post. When the limit post displaces, the reinforced support restraint arm plate can rotate along the axis point of the connection between the reinforced support restraint arm plate and the central hole through the pin plate, and then the two reinforced support restraint arm plates are clamped together, making it easy to wear the device on the waist;

[0014] 2. When the device of the present invention is worn on the body, the elastic stopper contacts the user's body, improving the comfort of wearing the device. The setting of the limit arc plate and the installation cavity groove facilitates the installation of the reinforced life-saving airbag main body on both sides of the device, and the limit arc plate facilitates the storage of the reinforced life-saving airbag main body after it deflates;

[0015] 3. The user puts the legs into each elastic restraint band, and makes the pressure water level sensor located at the ankle, while the connecting strip can be tied to the leg, making it easy for the pressure water level sensor to monitor the pressure of the water depth and making it easy for the device to eject the reinforced life-saving airbag main body, ensuring the safety of the device during use;

[0016] 4. When the pressure water level sensor detects a pressure change exceeding the preset threshold, the controller determines that it is necessary to trigger the reinforced life-saving airbag main body, sends an instruction to the airbag ignition inflation device, makes it ignite and inflate, and makes the reinforced life-saving airbag main body quickly fill with gas and pop open, enabling the user to float on the water surface and effectively realizing the function of active life-saving;

[0017] In summary, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the reinforced support restraint arm plate can rotate along the axis point of the connection between the reinforced support restraint arm plate and the central hole through the pin plate, and then the two reinforced support restraint arm plates are clamped together, making it easy to wear the device on the waist. The connecting strip can be tied to the leg, making it easy for the pressure water level sensor to monitor the pressure of the water depth and making it easy for the device to eject the reinforced life-saving airbag main body, ensuring the safety of the device during use. The controller determines that it is necessary to trigger the reinforced life-saving airbag main body, sends an instruction to the airbag ignition inflation device, makes it ignite and inflate, and makes the reinforced life-saving airbag main body quickly fill with gas and pop open, enabling the user to float on the water surface and effectively realizing the function of active life-saving.

[0033] As shown in the attached Figures 1-8 For a movable life-saving waist belt in water area, through the life-saving components arranged on the nylon support frame 1, the reinforced support restraint arm plate 2 can rotate along the axis point at the connection of the reinforced support restraint arm plate 2 and the central hole 304 through the pin plate 206, and then the two reinforced support restraint arm plates 2 are clamped together, which is easy to wear the device on the waist. The connecting strip 102 can be tied to the leg, which is easy for the pressure water level sensor 104 to monitor the water depth pressure, and it is easy for the device to eject the reinforced life-saving airbag main body 203 to ensure the safety of the device during use. When the controller 105 determines that it is necessary to trigger the reinforced life-saving airbag main body 203, it sends an instruction to the airbag ignition inflation device 101 to ignite and inflate it, so that the reinforced life-saving airbag main body 203 is quickly filled with gas and pops open, enabling the user to float on the water surface, effectively realizing the function of active life-saving, and the specific structure of the components is as follows;

[0034] The life-saving component includes an airbag ignition and inflation device 101 disposed on the top of the nylon support frame 1 and used to force the inflation of the reinforced life-saving airbag main body 203. Two connecting bars 102 are provided at the bottom of the airbag ignition and inflation device 101, and pressure water level sensors 104 for detecting water pressure at different depths are provided at the bottom of each connecting bar 102. A number of elastic restraint belts 103 for limiting are stacked on both connecting bars 102. A controller 105 is provided on the nylon support frame 1. An outer support frame 106 for support is provided on one side of the surface of the nylon support frame 1, and an alarm 107 for alarming is provided on the outer support frame 106;

[0035] Reinforced support restraint arm plates 2 with adjustable angles are provided on both sides of the nylon support frame 1. A limiting arc plate 201 for support is provided on one side of each reinforced support restraint arm plate 2. Installation cavity grooves 202 for installing the reinforced life-saving airbag main body 203 are provided on both limiting arc plates 201. An elastic blocking member 204 for protection is provided on the side of the reinforced support restraint arm plate 2 away from the limiting arc plate 201. A support shaft 205 for support is provided at one end of the reinforced support restraint arm plate 2. A shaft pin plate 206 is provided on the support shaft 205. The airbag ignition and inflation device 101 is connected to the reinforced life-saving airbag main body 203 through a reinforced elastic catheter 207, and a one-way valve is provided at the connection between the reinforced elastic catheter 207 and the reinforced life-saving airbag main body 203;

[0036] A dislocation opening 305 is provided on the nylon support frame 1 and located between the two reinforced support restraint arm plates 2. An electric push rod 3 for driving is provided in the dislocation opening 305. A connecting column 301 is provided at one end of the electric push rod 3. Two shaft pin pull rods 302 are rotatably connected to the connecting column 301. A limiting column 303 is provided at the output end of the electric push rod 3. The ends of the connecting column 301, the shaft pin pull rods 302, and the limiting column 303 respectively extend to the shaft pin plates 206 to which the two support shafts 205 belong and are rotatably connected to the shaft pin plates 206. Central holes 304 for rotatably connecting the reinforced support restraint arm plates 2 are provided at the top and bottom of the inner cavity of the dislocation opening 305 on the nylon support frame 1.

[0037] During use according to the above structure, when the user wears the device made by the present invention, the device is placed behind the waist. The output end of the electric push rod 3 extends to drive the displacement of the limiting column 303. When the limiting column 303 displaces, the reinforced support restraint arm plates 2 can rotate along the axis point at the connection between the reinforced support restraint arm plates 2 and the central holes 304 through the shaft pin plates 206, and then the two reinforced support restraint arm plates 2 are clamped to each other, making it easy to wear the device on the waist;

[0038] At the same time, the user extends his legs into each elastic restraint belt 103, and enables the pressure water level sensor 104 to be located at the ankle, and the connecting strip 102 can be tied to the leg. When drowning occurs, if the pressure water level sensor 104 monitors the water depth of about 1.5 meters below the water surface, the pressure is about 9800 Pascal Pa. When the pressure water level sensor 104 detects a pressure change exceeding a preset threshold, it will send a signal to the controller 105. The controller 105 sends a signal and determines whether it is necessary to trigger the airbag ignition and inflation device 101 of the enhanced life-saving airbag body 203. If the controller 105 determines that the enhanced life-saving airbag body 203 needs to be triggered, it sends a command to the airbag ignition and inflation device 101 to ignite and inflate it and make the enhanced life-saving airbag body 203 quickly filled with gas and pop open, so that the user can float on the water surface, effectively realizing the active life-saving function;

[0039] When the device is worn, the elastic stopper 204 contacts the user's body, which improves the wearing comfort of the device. The arrangement of the limiting arc plate 201 and the mounting cavity 202 facilitates the installation of the reinforced life-saving airbag body 203 on both sides of the device, and the limiting arc plate 201 facilitates the subsequent storage of the reinforced life-saving airbag body 203 after it is deflated.

[0040] When the connecting strip 102 is tied to the leg by the elastic restraint belt 103, it is used to ensure that the connecting strip 102 will not fall off when the user is swimming. The setting of the offset opening 305 facilitates the installation of the electric push rod 3 and the axle pin pull rod 302, so that the electric push rod 3 and the axle pin pull rod 302 can be offset through the offset opening 305 to avoid interference with the nylon support frame, thereby ensuring the convenience of its installation.

[0041] Different from the prior art, the present application discloses a movable life-saving belt in water areas. The reinforced support and restraint arm plate 2 can be rotated along the axis point of the connection between the reinforced support and restraint arm plate 2 and the center hole 304 through the axle pin plate 206, so that the two reinforced support and restraint arm plates 2 are clamped together, and the device is easy to wear on the waist. The connecting strip 102 can be tied to the legs. The pressure water level sensor 104 is easy to monitor the pressure of the water depth, and the device is easy to pop out the reinforced life-saving airbag body 203 to ensure the safety of the device when in use. The controller 105 determines that the reinforced life-saving airbag body 203 needs to be triggered, and sends a command to the airbag ignition and inflation device 101 to ignite and inflate it and make the reinforced life-saving airbag body 203 quickly filled with gas and pop open, so that the user can float on the water surface, effectively realizing the function of active life-saving.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
