Description

Technical Field

[0001] This invention belongs to the field of lifesaving equipment technology, specifically a swimming ring with self-inflating function. Background Technology

[0002] A swimming ring is an aid used in water, primarily to provide buoyancy and help people maintain balance when engaging in water activities or learning to swim.

[0003] In existing swimming ring technology, the inflatable swimming ring needs to be kept inflated during use and transported to the swimming destination. Because the inflated swimming ring takes up a certain amount of space, it is inconvenient to carry and also takes up a lot of space during transportation, especially for multiple swimming rings, which actually take up even more space. In addition, when inflated, it is easy to collide and rub against the external environment during carrying and transportation, which poses a risk of the swimming ring being cut or punctured. On-site inflation at the destination requires carrying inflation equipment and performing inflation operations, resulting in poor overall use.

[0004] Furthermore, existing swimming rings are typically worn around the user's waist for buoyancy protection. However, due to differences in individual waist circumference and swimming ring size, the rings may have excessively large gaps or be too loose, making them prone to slipping off and losing their effective protective function, resulting in poor actual performance. Summary of the Invention

[0005] The purpose of this invention is to provide a swimming ring with a self-inflating function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a swimming ring with self-inflating function, comprising an outer ring body, an inner support tube inside the outer ring body, an air storage component fixedly sleeved on the outer surface of the inner support tube, one end of the air storage component fixedly sleeved on the outer side of the outer ring body, a distribution sleeve fixedly sleeved on the outer surface of the inner support tube, a distribution control component movably sleeved inside the distribution sleeve, an air outlet end of the air storage component fixedly connected to the distribution sleeve, an assembly component fixedly sleeved on the outer side of the outer ring body, an outer end of the distribution control component movably sleeved in the assembly component, an auxiliary elastic bladder fixedly provided on the outer side of the outer ring body near the inner ring, the distribution control component guiding the exhaust of the air storage component to the interior of the outer ring body and the interior of the auxiliary elastic bladder respectively, and a handle fixedly provided on the outer side of the outer ring body.

[0007] Preferably, the gas storage assembly includes a gas storage tank, an exhaust pipe, a connecting pipe, a connecting sleeve, and an injection valve. The gas storage tank is fixedly sleeved on the outer surface of the supporting inner tube. One end of the exhaust pipe is fixedly connected to the gas storage tank and communicates with the inside of the gas storage tank. The other end of the exhaust pipe is fixedly connected to the distribution sleeve. One end of the connecting pipe is fixedly connected to the gas storage tank and communicates with the inside of the gas storage tank. The other end of the connecting pipe is fixedly sleeved in the connecting sleeve. The connecting sleeve is fixedly sleeved on the outer surface of the outer ring body. The injection valve is fixedly connected to the outer end of the connecting pipe and located in the connecting sleeve.

[0008] Preferably, the connecting pipe is a flexible pipe and the connecting sleeve is a rubber sleeve.

[0009] Preferably, the distribution sleeve includes a sleeve frame, an internal cavity, and side holes. The sleeve frame is fixedly sleeved on the outer surface of the supporting inner tube. The internal cavity is opened inside the sleeve frame. The side holes are opened on both sides of the sleeve frame. One end of the side hole is connected to the internal cavity, and the other end is connected to the exhaust pipe.

[0010] Preferably, the distribution control assembly includes a connecting rod, a movable column, a spring, an intermediate conduit, a bypass groove, and a bottom tube. One end of the connecting rod is movably sleeved in the sleeve frame. The movable column is movably sleeved in the internal cavity and fixedly connected to the connecting rod. One end of the spring is fixedly connected to the movable column, and the other end is fixed in the internal cavity. The intermediate conduit is fixedly sleeved inside the movable column and extends through both sides of the outer surface of the movable column. The bypass groove is opened inside the movable column. One end of the bottom tube is fixedly connected to and communicates with the intermediate conduit, and the other end passes through the outer surface of the movable column and extends to the outside. A sliding groove is opened at the bottom of the sleeve frame, and the bottom tube is slidably sleeved in the sliding groove.

[0011] Preferably, the side hole is located on the moving path of the intermediate conduit, the air inlet end of the bypass groove is located on both sides of the outer surface of the movable column, the air outlet end of the bypass groove passes through the end of the movable column, and the side hole is located on the moving path of the air inlet end of the bypass groove.

[0012] Preferably, the assembly component includes an assembly sleeve, an elastic ring, a positioning ring, and a sealing cap. The assembly sleeve is fixedly fitted onto the outer side of the outer ring body. The elastic ring and the positioning ring are fixedly fitted onto the assembly sleeve from the inside to the outside. The elastic ring and the positioning ring are both fitted onto the outside of the connecting rod. The sealing cap is fitted onto the front opening of the assembly sleeve and is connected to the assembly sleeve through an elastic connecting part.

The cross-section of the auxiliary elastic bladder is semi-circular.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention utilizes a supporting inner tube to support the gas storage component, connecting the gas storage component to the distribution sleeve. In conjunction with the assembly component and the distribution control component, the distribution control component is pulled from the outside to conduct gas through the gas storage component. This, along with the moving and connected middle and bottom tubes, releases gas into the interior of the outer ring body, achieving inflation and expansion of the outer ring body. This enables automatic inflation of the swimming ring, reducing handling volume, improving portability, and providing a simple and fast automatic inflation operation.

[0017] 2. By utilizing the connecting sleeve and injection valve in the gas storage component, the present invention can release gas after actual inflation and expansion, and inject and store gas through the injection valve when inflation is needed, storing the gas in the gas storage tank for future use, thereby achieving continuous self-inflation and expansion after gas storage.

[0018] 3. This invention utilizes the combination of the distribution sleeve and the distribution control component to inflate the air storage component in different directions by pushing the connecting rod in the opposite direction. After the swimming ring is fully inflated, the remaining air in the air storage component can be introduced into the auxiliary elastic bladder through the bypass pipe, thereby inflating the auxiliary elastic bladder. With the auxiliary elastic bladder connected in a ring, distributed in the inner circle, it further wraps around the wearer's waist through its own air expansion, achieving a tighter fit and improving the wearing stability of the swimming ring. This prevents it from coming off during use and losing its protective effect, resulting in good actual performance. Attached Figure Description

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 8 As shown, this embodiment of the invention provides a swimming ring with a self-inflating function, including an outer ring body 1. The outer ring body 1 has a supporting inner tube 2 inside. An air storage component 3 is fixedly sleeved on the outer surface of the supporting inner tube 2. One end of the air storage component 3 is fixedly sleeved on the outer side of the outer ring body 1. A distribution sleeve 5 is fixedly sleeved on the outer surface of the supporting inner tube 2. A distribution control component 6 is movably sleeved inside the distribution sleeve 5. The air outlet end of the air storage component 3 is fixedly connected to the distribution sleeve 5. An assembly component 7 is fixedly sleeved on the outer side of the outer ring body 1. The outer end of the distribution control component 6 is movably sleeved in the assembly component 7. An auxiliary elastic bladder 9 near the inner ring is fixedly provided on the outer side of the outer ring body 1. The distribution control component 6 guides the exhaust of the air storage component 3 to the interior of the outer ring body 1 and the interior of the auxiliary elastic bladder 9 respectively. A handle 4 is fixedly provided on the outer side of the outer ring body 1.

[0031] Example 1: In use, when self-inflation is required, hold the uninflated swimming ring and locate the sealing cover 74 on the assembly assembly 7 along the outer ring body 1. Pull the sealing cover 74 out of the assembly assembly 71, and pull the connecting rod 61 sleeved in the assembly assembly 71. Pull the connecting rod 61 outward, causing the connecting rod 61 to drive the movable column 62 to move in the internal cavity 52 and compress the spring 63. As the movable column 62 in the distribution control assembly 6 moves, the intermediate conduit 64 sleeved in the movable column 62 moves synchronously. The intermediate conduit 64 communicates with the side holes 53 on both sides. At this time, the air stored in the air storage assembly 3... The gas in the middle gas tank 31 is quickly released into the side hole 53 of the sleeve frame 51 through the exhaust pipe 32, and then introduced into the middle conduit 64 through the side hole 53. It is also introduced into the interior of the outer ring body 1 through the bottom pipe 66, causing the outer ring body 1 to inflate and expand, completing the automatic inflation. When the gas is released after use, the gas injection valve 35 is opened, and the connecting rod 61 is pulled again, so that the outer ring body 1 discharges the internal gas through the distribution sleeve 5 and the gas storage component 3, completing the venting. When the gas injection valve 35 is opened separately and connected to the external gas supply mechanism, the gas storage component 3 is re-injected and stored for backup.

[0032] First, by using the inner support tube 2 to support the air storage component 3 and connecting the air storage component 3 with the distribution sleeve 5, and cooperating with the assembly component 7 and the distribution control component 6, the distribution control component 6 is pulled from the outside to conduct the air storage component 3. In conjunction with the moved and connected middle conduit 64 and bottom tube 66, the gas is released into the interior of the outer ring body 1, realizing the inflation and expansion of the outer ring body 1. This achieves automatic inflation of the swimming ring, reduces the volume of handling, improves portability, and the automatic inflation operation is simple and the inflation speed is fast.

[0033] In addition, by utilizing the connecting sleeve 34 and the air injection valve 35 in the air storage component 3, gas can be released after actual inflation and expansion, and when inflation is needed, gas can be injected and stored in the air storage tank 31 for future use, thereby achieving continuous self-inflation and expansion after gas storage.

[0034] Example 2: When the swimming ring is not found to fit the waist after being put on, the sealing cover 74 is opened and the connecting rod 61 is pressed down, which stretches the spring 63 and the movable column 62 slides in the internal cavity 52, so that the air inlet end of the bypass groove 65 is connected to the side hole 53, so that the air storage component 3 inputs pressurized air into the bypass groove 65 and into the auxiliary elastic bladder 9 through the bypass pipe 8, so that the auxiliary elastic bladder 9 inflates and expands, and wraps and clamps the waist.

[0035] First, by utilizing the distribution sleeve 5 and the distribution control component 6 again, the air storage component 3 is inflated in different directions by pushing the connecting rod 61 in the opposite direction. After the swimming ring is fully inflated, the remaining air in the air storage component 3 can be input into the auxiliary elastic bladder 9 through the bypass pipe 8, thereby inflating the auxiliary elastic bladder 9. With the auxiliary elastic bladder 9 connected in a ring, distributed in the inner circle, it further wraps around the wearer's waist through its own air expansion, thereby further tightening and improving the wearing stability of the swimming ring, preventing it from coming off during use and losing its protective effect. The actual use effect is good.

[0036] The gas storage assembly 3 includes a gas storage tank 31, an exhaust pipe 32, a connecting pipe 33, a connecting sleeve 34, and an injection valve 35. The gas storage tank 31 is fixedly sleeved on the outer surface of the supporting inner tube 2. One end of the exhaust pipe 32 is fixedly connected to the gas storage tank 31 and communicates with the inside of the gas storage tank 31. The other end of the exhaust pipe 32 is fixedly connected to the distribution sleeve 5. One end of the connecting pipe 33 is fixedly connected to the gas storage tank 31 and communicates with the inside of the gas storage tank 31. The other end of the connecting pipe 33 is fixedly sleeved in the connecting sleeve 34. The connecting sleeve 34 is fixedly sleeved on the outer surface of the outer ring body 1. The injection valve 35 is fixedly connected to the outer end of the connecting pipe 33 and is located in the connecting sleeve 34.

[0037] By utilizing the gas storage component 3 to store gas, it can be released and self-inflated when needed. The gas injection valve 35 is an existing gas valve, which can be opened to release gas and to be inflated and stored with an external gas supply mechanism.

[0038] Among them, the connecting pipe 33 is a flexible pipe, and the connecting sleeve 34 is a rubber sleeve.

[0039] The flexible connecting pipe 33 connects the outer ring body 1, the gas storage component 3, and the supporting inner pipe 2 into a whole. The connecting sleeve 34 made of rubber sleeve realizes flexible installation and avoids the rigid effect from puncturing the outer ring body 1.

[0040] The distribution sleeve 5 includes a sleeve frame 51, an internal cavity 52, and a side hole 53. The sleeve frame 51 is fixedly sleeved on the outer surface of the supporting inner tube 2. The internal cavity 52 is opened inside the sleeve frame 51. The side hole 53 is opened on both sides of the sleeve frame 51. One end of the side hole 53 is connected to the internal cavity 52, and the other end is connected to the exhaust pipe 32.

[0041] Distribution control is achieved by using distribution sleeve 5, guiding the gas released from gas storage component 3 into the system, and cooperating with distribution control component 6 to achieve outflow in different directions.

[0042] The distribution control component 6 includes a connecting rod 61, a movable column 62, a spring 63, an intermediate conduit 64, a bypass groove 65, and a bottom tube 66. One end of the connecting rod 61 is movably sleeved in the sleeve frame 51. The movable column 62 is movably sleeved in the internal cavity 52 and fixedly connected to the connecting rod 61. One end of the spring 63 is fixedly connected to the movable column 62, and the other end is fixed in the internal cavity 52. ​​The intermediate conduit 64 is fixedly sleeved inside the movable column 62 and extends through both sides of the outer surface of the movable column 62. The bypass groove 65 is formed in... Inside the movable column 62, one end of the bottom tube 66 is fixedly connected to and communicates with the intermediate conduit 64, and the other end passes through the outer surface of the movable column 62 and extends to the outside. The bottom of the sleeve frame 51 is provided with a sliding groove 10, and the bottom tube 66 is slidably sleeved in the sliding groove 10. The side hole 53 is located on the moving path of the intermediate conduit 64. The air inlet end of the bypass groove 65 is located on both sides of the outer surface of the movable column 62, and the air outlet end of the bypass groove 65 passes through the end of the movable column 62. The side hole 53 is located on the moving path of the air inlet end of the bypass groove 65.

[0043] The distribution control component 6 moves laterally to change the position of the intermediate conduit 64 and the bypass groove 65, thereby achieving communication with the side hole 53 and realizing gas output in different directions. The slide groove 10 adapts to the sliding movement of the bottom pipe 66, providing sliding space to ensure that gas is input into the outer ring body 1 through the bottom pipe 66.

[0044] The assembly component 7 includes an assembly piece 71, an elastic ring 72, a positioning ring 73, and a sealing cover 74. The assembly piece 71 is fixedly sleeved on the outer side of the outer ring body 1. The elastic ring 72 and the positioning ring 73 are fixedly sleeved in the assembly piece 71 from the inside to the outside. The elastic ring 72 and the positioning ring 73 are both sleeved on the outside of the connecting rod 61. The sealing cover 74 is sleeved on the front opening of the assembly piece 71 and is connected to the assembly piece 71 through an elastic connecting part.

[0045] Assembly component 7 enables the movable assembly of connecting rod 61, and works with elastic ring 72 to maintain dynamic sealing, while the rigid structure of positioning ring 73 maintains stable support and prevents connecting rod 61 from shifting.

[0046] Among them, the fitting 71 and the sealing cover 74 are made of the same material, which is rubber sleeve, and the positioning ring 73 is a rigid ring.

[0047] The rubber sleeve-made fitting 71 and the sealing cover 74 can be elastically fitted together to maintain the stability of the damping effect and improve the external flexible protection effect.

[0048] One end of the sleeve 51 is fixedly connected to a bypass pipe 8. One end of the bypass pipe 8 is connected to the internal cavity 52, and the other end passes through the outer ring body 1 and is connected to the interior of the annular auxiliary elastic bladder 9. The cross-section of the auxiliary elastic bladder 9 is semi-circular.

[0049] By utilizing the conduction effect of the bypass tube 8, gas is introduced into the auxiliary elastic bladder 9 to achieve expansion, and the inner ring is used to wrap and clamp the waist, improving wearing stability.

[0050] The working principle and usage process of this invention: When self-inflation is required, hold the uninflated swimming ring and locate the sealing cover 74 on the assembly assembly 7 along the outer ring body 1. Pull the sealing cover 74 out of the assembly assembly 71 and pull the connecting rod 61 sleeved in the assembly assembly 71. Pull the connecting rod 61 outward, causing the connecting rod 61 to drive the movable column 62 to move in the internal cavity 52 and compress the spring 63. As the movable column 62 in the distribution control assembly 6 moves, the intermediate conduit 64 sleeved in the movable column 62 moves synchronously. The intermediate conduit 64 is connected to the side holes 53 on both sides. At this time, the gas stored in the gas tank 31 in the gas storage assembly 3 is quickly released into the side holes 53 of the frame 51 through the exhaust pipe 32, and the gas is input into the intermediate conduit 64 through the side holes 53, and input into the outer side through the bottom pipe 66. Inside the main body 1, the outer ring body 1 is inflated, completing automatic inflation. When the gas is released after use, the air injection valve 35 is opened, and the connecting rod 61 is pulled again, so that the outer ring body 1 releases the internal gas through the distribution sleeve 5 and the air storage component 3, completing the venting. When the air injection valve 35 is opened separately and connected to the external air supply mechanism, the air storage component 3 is re-injected and stored for later use. When the swimming ring is found to be not fitted to the waist, the sealing cover 74 is opened and the connecting rod 61 is pressed down, so that the spring 63 is stretched and the movable column 62 slides in the internal cavity 52, so that the air inlet end of the bypass groove 65 is connected to the side hole 53, so that the air storage component 3 inputs pressurized air into the bypass groove 65 and into the auxiliary elastic bladder 9 through the bypass pipe 8, so that the auxiliary elastic bladder 9 inflates and expands, wrapping and clamping the waist.
