Embodiment 1

[0046] ​In this embodiment, the inflatable structure body 1 is in a strip-shaped air bag structure. The inflatable structure body 1 mainly functions to form a closed space, can be inflated to generate buoyancy in water, and is in a strip-shaped structure, which is not limited to the specific shapes of straight strip, C-shaped, S-shaped, etc., as long as it has a certain length-width ratio and can achieve a certain stretching distance, and is within the protection scope of the patent.

[0047] In this embodiment, the strip-shaped structure of the inflatable structure body 1 is arranged to form a ring shape, which is convenient for being sleeved on a human body. The shape of the inflatable structure body 1 in this embodiment cooperates with the shape of the skeleton 3. The inflatable structure body 1 can be arranged as a single layer or two or more layers. The material of the inflatable structure body 1 is waterproof and air-tight, such as the material of a life buoy or a swimming ring, for example, a plastic film, cloth with a plastic coating, etc., but is not limited to the above-mentioned materials.

[0048] In this embodiment, the inflatable structure body 1 is a flexible inflatable structure, which can be, for example, an air bag, a swimming ring, a life buoy, etc. The inflatable structure body 1 is provided with a stretching end 4 at both ends.

[0049] In this embodiment, the skeleton 3 cooperates with the inflatable structure body 1. The skeleton 3 is in a telescopic nested structure or a telescopic stacked structure, and is used to support the inflatable structure body 1. The skeleton 3 is arranged on the inflatable structure body 1, and is connected with the inflatable structure body 1. The skeleton 3 is in a telescopic nested structure or a telescopic stacked structure.

[0050] In this embodiment, the skeleton 3 is arranged as a spiral structure 7, which can be telescopic nested or telescopic stacked. The spiral diameter of the spiral structure 7 gradually decreases or gradually increases from the middle position of the skeleton 3 to both ends. The position with the maximum or minimum diameter is close to the middle position or the center position, which is within the protection scope of the patent.

[0051] In this embodiment, the skeleton 3 can be integrally formed or can be a spliced structure in a tower-shaped spring structure. The splicing mode can be relative splicing at the bottom or relative splicing at the top of the tower-shaped spring structure.

[0052] In this embodiment, when the skeleton 3 adopts the spiral structure 7, the material of the skeleton 3 adopts a material with supporting and elastic properties, such as plastic and metal with telescopic function.

[0053] When the spiral structure 7 adopts a material with small elasticity, the inflation of the inflatable structure body 1 is realized by stretching.

[0054] The spiral structure 7 also has an optimal solution, that is, the spiral structure 7 is made of a material with relatively high elasticity and has a spring property. When the material with relatively high elasticity is used, the spiral structure 7 is stored in the storage bag in the unused state, and as long as it is taken out, the inflatable structure body 1 is rapidly and automatically stretched under the elastic force of the spiral structure 7, thereby realizing rapid inflation. Even for the group with insufficient strength or the group with insufficient arm stretching distance, it has good use effect, and the inflation efficiency is higher.

[0055] The spiral structure 7 can be provided as a telescopic nested structure, and the largest support body can be provided as a storage box, which has the effects of ensuring the minimum storage volume and rapid inflation.

[0056] If the child-mother buckle or magnet is arranged at both ends of the skeleton 3, the child-mother buckle or magnet only needs to be pulled apart to realize elastic and rapid inflation.

[0057] In addition, the spiral structure 7 can also be provided as a telescopic stacked structure. The telescopic stacked structure has a larger volume after being stored, which is inconvenient to carry. It is suitable for occasions where the storage volume is not strictly required, such as vehicle-mounted or fixed location setting. The child-mother buckles or magnets that attract each other are arranged on the support bodies at both ends of the skeleton 3. After the skeleton 3 is contracted, the child-mother buckles or magnets are clamped to realize the fixed form after storage, which is convenient to carry. The specific fixing structure can adopt the existing technology, and the main purpose is to fix the buoyancy device in the contracted state.

[0058] In the embodiment, the skeleton 3 is arranged on the inner surface or the interlayer or the outer surface of the inflatable structure body 1. That is, the skeleton 3 can be arranged on the inner surface of the inflatable structure body 1 and fixedly connected with the inner surface of the inflatable structure. When the inflatable structure body 1 is double-layered, the skeleton 3 can be arranged in the interlayer. The skeleton 3 can also be arranged on the outer surface of the inflatable structure body 1. The connection mode of the skeleton 3 and the inflatable structure body 1 can adopt glue connection, buckle connection, thermal covering connection and the like, which are not limited to the above connection modes.

[0059] In the embodiment, the inflatable structure body 1 or the skeleton 3 is provided with an air inlet and exhaust end. The air inlet and exhaust end is provided with a gas valve 2. The gas valve 2 adopts a one-way valve. The gas valve 2 is used to realize inflation of the inflatable structure body 1. The gas valve 2 is arranged on the skeleton 3 or the inflatable structure body 1. The gas valve 2 can adopt a one-way valve or a gas valve 2 with a function similar to a one-way valve, which is not limited to a one-way valve. A manual on-off inflation valve 2 can also be used. The air inlet and exhaust end can also not be provided with a gas valve 2. It also belongs to the protection scope of the present patent to manually and quickly close the air inlet and exhaust end, which only has a lower effect than the gas valve 2.

[0060] The skeleton 3 of the optimal structure is a bipyramidal symmetrical structure, the bipyramidal symmetrical structure is opposite at the top of the bipyramid or opposite at the bottom, and the size of the cone half angle is adjusted to enable the nesting of adjacent support bodies. The cone described in the patent is a conical structure, and the tip of the cone can be pointed or non-pointed. The non-pointed type includes flat, curved or inclined surfaces, etc. For example, it can be an elongated circular truncated cone structure. The bipyramidal structure not only ensures good nesting effect, but also ensures good inflation effect, which is easier to inflate than a columnar structure, and ensures the realization of nesting. The use of a columnar structure can realize a stacked structure.

[0061] In addition, support bodies with approximately equal diameters can also be used. The support bodies with approximately equal diameters can realize the function of stacking, and are used to set up a telescopic stacking structure, which is suitable for occasions with low requirements for the volume and aesthetics after storage. The effect and aesthetics after storage of this structure are not as good as those of the telescopic nesting structure. Although this structure has some shortcomings, it can be applied to occasions with low requirements for storage volume. This structure is also included in the protection range of the patent.

[0062] In the embodiment, a locking structure is also included, which is used to connect the two ends of the inflatable structure body 1. The locking structure can use a male-female plug-in buckle, and the male buckle and the female buckle are respectively arranged at the two ends of the inflatable structure body 1, but are not limited to the letter plug-in buckle. A tether or other structure that can realize the connection and fixation of the two ends of the inflatable structure body 1 can also be used. As long as the two ends of the buoyancy device can be connected, it is within the protection range of the patent.

[0063] In the embodiment, the support bodies at the two ends of the skeleton 3 are provided with a male-female buckle or mutually attractive magnets, which are clamped after the skeleton 3 is contracted, facilitating storage. Embodiment 2

[0064] On the basis of embodiment 1, the skeleton 3 structure of embodiment 1 is replaced by another skeleton 3 structure, which can realize the functions of telescopic nesting or superposition. The skeleton 3 includes a plurality of support bodies, and the plurality of support bodies are arranged at intervals. When it is a telescopic nesting structure, the diameter of the support body gradually decreases or gradually increases from the middle position to the end position of the skeleton 3. The adjacent support bodies can be nested, and the support bodies arranged at intervals are parallel and connected by the flexible structure body 1. It has the rigidity of support and the flexibility of stretching, and there is no rigid resistance in the axial direction. In summary, the skeleton 3 of this embodiment includes two structure states after contraction. One is a telescopic nesting structure, and the other is a telescopic superposition structure. The telescopic nesting structure is more advantageous than the telescopic superposition structure because the telescopic superposition structure is to superimpose the thickness of a plurality of skeletons 3 and the flexible structure body 1 after contraction. The volume after storage will be larger, which is suitable for occasions where the volume requirement is not very strict, such as vehicle-mounted occasions, fixed-position occasions, and the like. It is somewhat insufficient for occasions where it needs to be carried and stored. For occasions where it needs to be carried and stored, the telescopic nesting structure is adopted. The skeleton 3 of the telescopic nesting structure can realize mutual nesting, realize the storage of the support body in the largest support body, and the thickness will not be superimposed. The thickness depends on the thickness of the largest support body, and the flexible structure body 1 after contraction is filled in the gap between the nested support bodies. It not only does not occupy additional area, but also is more beautiful. In addition, the largest support body can be arranged as a storage box structure, and a handle is arranged. All the support bodies are nested in the support body of the storage box structure. The adjacent support bodies are nested in each other, forming a large ring structure. The gap between the ring structures contains the flexible structure body 1. The support bodies are arranged at intervals and in parallel. On the one hand, it ensures that the thickness is small in the axial direction after nesting. On the other hand, it ensures that it has flexibility and rigidity. It maximizes the flexibility in the axial direction, facilitates the realization of stretching without resistance, and quickly expands to form negative pressure. At the same time, it ensures the radial rigid support, facilitates the inflation of the internal space of the flexible structure body 1, and ensures the smoothness of the air inlet. Through the arrangement of the flexible and rigid skeleton 3 structure, the flexible structure body 1 is realized to maximize the space for quick stretching and air inlet, and the inflation effect is ensured.

[0065] In this embodiment, the skeleton 3 includes a plurality of closed ring support bodies 5 or non-completely closed ring support bodies 6. Adjacent closed ring support bodies 5 or non-completely closed ring support bodies 6 can be nested or superimposed. The support body of the skeleton 3 can be a closed ring structure, a non-completely closed ring structure, or an approximately ring structure, all of which are within the scope of protection of this patent.

[0066] In this embodiment, the support body is in the form of a closed or non-completely closed circle, ellipse, rectangle, trapezoid, or triangle. However, it is not limited to the above shapes, and the support body includes both completely closed and non-completely closed cases. As long as the shape can realize the functions of nesting or superposition, it can be listed as the shape explained in this patent. The adjacent support bodies are connected by the flexible structure body 1.

[0067] In this embodiment, the material of the support body can be plastic, wood, metal, etc. with supporting performance, not limited to the above materials.

[0068] The optimal structure is a symmetrical structure, i.e. the support body has the maximum or minimum diameter at the central position of the skeleton 3. When the diameter of the support body at the central position is maximum, the diameter of the support body gradually decreases from the center to both ends. When the diameter of the support body at the central position is minimum, the diameter of the support body gradually increases from the center to both ends.

[0069] In this embodiment, when the two ends of the skeleton 3 with telescopic nesting or telescopic stacking function are pulled and stretched, or the two ends of the inflatable structure body 1 are pulled and stretched, a negative pressure is formed in the inflatable structure body 1, and external gas enters the inflatable structure body 1 through the gas inlet and exhaust end to inflate the inflatable structure body 1. The skeleton 3 can realize the inflation of the inflatable structure body 1 when the skeleton 3 is pulled and stretched. The inflatable structure body 1 flexibly connects between adjacent skeletons 3 through the inflatable structure body 1, has rigidity and flexibility, is completely flexible in the axial direction, and is rigidly supported in the radial direction to support the gas inlet space and ensure the tensile ductility and flexibility of the axis, thereby achieving the best gas inlet effect. Embodiment 3

[0070] Based on embodiments 1 and 2, the inflatable structure body 1 and the skeleton 3 are integrally formed or the inflatable structure body 1 and the skeleton 3 are spliced into a sealed structure. One of the structures is integrally formed, i.e. a rib-like rigid support structure is processed at the corresponding position of the skeleton 3 on the inflatable structure body 1 during processing, and the structure is arranged in a regular manner as a support body structure arranged at intervals or a spiral structure 7. The other structure is spliced, i.e. the inflatable structure body 1 is no longer an integrally formed structure, but is spliced from several pieces, and the spliced seams of the several pieces are the skeleton 3 structure, which adopts the skeleton 3 structure form of embodiments 1 or 2. Embodiment 4

[0071] The assembly method of the patent comprises:

[0072] The skeleton 3 with telescopic nesting or telescopic stacking function is matched with the inflatable structure body 1 or integrally formed or spliced, and the gas valve 2 is arranged on the skeleton 3 or the inflatable structure body 1.

[0073] The locking structure is arranged at both ends of the skeleton 3 or the inflatable structure body 1.

[0074] The skeleton 3 can be arranged inside the inflatable structure body 1 or outside the inflatable structure body 1, or arranged in the interlayer when the inflatable structure body 1 has an interlayer, or the inflatable structure body 1 piece structure is spliced with the skeleton 3, and the skeleton 3 is arranged at the joint of the piece;

[0075] Or, the inflatable structure body 1 is directly integrated with the matching framework 3 rib structure during processing.

[0076] The assembly described in this embodiment is not limited to assembly, and can be integrally formed by processing. Embodiment 5

[0077] The use method of the patent comprises:

[0078] By pulling the two ends of the framework 3 with telescopic nesting or telescopic stacking function to stretch, or by pulling the two ends of the inflatable structure body 1 to stretch, a negative pressure is formed in the inflatable structure body 1, and external gas enters the inflatable structure body 1 through the air valve 2 to inflate the inflatable structure body 1.

[0079] Or,

[0080] By the elastic spiral structure 7 framework 3 supporting the inflatable structure body 1, a negative pressure is formed in the inflatable structure body 1, and external gas enters the inflatable structure body 1 through the air valve 2 to inflate the inflatable structure body 1. When taken out of the storage bag, the compressed spiral structure framework automatically expands under the action of the elastic force, thereby driving the inflatable structure body to expand, thereby realizing automatic inflation of the inflatable structure body. This structure and new type of concept do not need to be stretched again, and are especially suitable for people who have no strength or have short arms, or by pulling the locking members at both ends of the spiral structure framework to release the locking, realizing elastic support inflation.

[0081] By connecting the two ends of the long strip-shaped water floating device to form a ring structure;

[0082] The ring-shaped water floating device is sleeved on the human body.

[0083] Or directly use a long strip, connect the inflatable structure body 1 by a traction rope, and then connect it with the human body.

[0084] Working principle:

[0085] When the user uses it, the user pulls the two ends of the floating device with both hands. Due to the supporting effect of the framework 3, a negative pressure is formed in the floating device, and air will enter the floating device through the air inlet and exhaust end to realize rapid inflation.

[0086] Or when the framework 3 with a spiral structure 7 of a material with relatively large elasticity is used, the buckle at both ends of the framework 3 is taken out of the storage bag or pulled apart, and under the elastic action of the spiral structure 7, the inflatable structure body 1 is automatically popped up to realize rapid automatic inflation.

[0087] When the user puts the buoyancy device around the waist and abdomen of the body and fixes it by the locking structure, the support bodies close to the body will be shortened, the internal volume of the buoyancy device will be reduced, the air will be extruded, and the air pressure will be increased, if the internal air pressure is still insufficient, the user can also blow air through the one-way air inlet valve 2 to make up for it.

[0088] The skeleton 3 of the telescopic nested structure can be nested, has a small storage volume, and is convenient to carry.

[0089] From the above description, it can be seen that the embodiments of the utility model realize the following technical effects:

[0090] The skeleton 3 with the telescopic nesting or telescopic stacking function is matched with or integrally formed with the inflatable structure body 1, and the air valve 2 is arranged on the skeleton 3 or the inflatable structure body 1. By pulling the two ends of the skeleton 3 with the telescopic nesting or telescopic stacking function or by pulling the two ends of the inflatable structure body 1, negative pressure is formed in the inflatable structure body 1, external air enters the inflatable structure body 1 through the air valve 2, and the inflatable structure body 1 is inflated. The inflatable structure body 1 is quickly inflated, and the technical effects of convenient carrying and rapid inflation are achieved.

[0091] By arranging the skeleton 3 in a telescopic nested structure, the volume after storage can be small, and the plurality of support bodies are nested in the largest support body.

[0092] By arranging the skeleton 3 in a telescopic nested spiral structure 7, not only the volume after storage can be small, but also the buckle clamped together at the two ends can be taken out or pulled apart from the storage bag, the inflatable structure body 1 can be automatically popped open and supported under the elastic action of the spiral structure 7, and rapid automatic inflation is achieved.

[0093] By arranging the skeleton 3 in a conical symmetrical structure, the inflation effect can be better, and the two ends can be connected to form a ring structure after inflation.

[0094] The above only describes preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can be changed and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
