Description

Technical Field

[0001] This invention relates to the field of inflatable support technology, and in particular to a method for connecting inflatable supports. Background Technology

[0002] The existing air-filled pipes on the market are all made using a high-temperature heat-sealing welding process. From the beginning to the final product, the production is done by manually stacking and welding step by step, which results in low production efficiency, high labor costs, and inconsistent skill levels among technicians. During high-temperature heat-sealing welding, problems such as product twisting and pipes of different sizes can easily occur, leading to unstable product quality. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide a method for connecting an inflatable support, which can decompose the three-dimensional shape of the inflatable support and unfold it into a planar structure for processing, so that the opening part in the planar material can stand up to form a connecting edge, and realize the fusion of two layers of connecting material at the overlapping part.

[0004] The technical solution adopted by the present invention to solve its technical problem is to provide an inflatable support connection method. The inflatable support is composed of multiple multi-way pipes and multiple straight pipes connected together. Each multi-way pipe is processed using a multi-way pipe method, and the straight pipes are connected to the multi-way pipes respectively using a fixed connection process.

[0005] The specific steps for processing multi-port pipes are as follows:

[0006] S1. First, flatten the elastic first connecting material, and then process at least one first through hole with a size smaller than the mold size on the first connecting material. The number of first through holes is the number of pipes in the multi-channel pipe minus two.

[0007] S11. The first connecting material is placed on the mold, and the inner wall of the first through hole is squeezed and raised by the mold to form a connecting edge. The pipe connector is placed on the mold so that the lower part of the pipe connector fits the outer surface of the connecting edge. The lower part of the pipe connector is pressed tightly against the connecting edge by the pressing device. The lower part of the pipe connector is fixedly connected to the connecting edge by the fixed connection process.

[0008] S12. A fixed connection process is used to fix the two opposite sides of the first connecting material together to form a multi-channel pipe.

[0009] As a further improvement of the present invention, the specific method of the fixed connection process is high-frequency welding, high-temperature heat sealing, or adhesive bonding.

[0010] As a further improvement of the present invention, the specific method for connecting the straight pipe to the multi-way pipe using the fixed connection process is as follows: one of the pipes of the multi-way pipe is sleeved on the mold, one side of the second connecting material is wrapped around the mold and tightly attached to the multi-way pipe, and the second connecting material is fixedly connected to the multi-way pipe.

[0011] As a further improvement of the present invention, the specific method of connecting the straight pipe to the multi-way pipe using the fixed connection process is as follows: the two opposite sides of the second connecting material are fixedly connected to form a straight pipe using the fixed connection process, one of the multi-way pipes is sleeved on the mold, the straight pipe is sleeved on the mold and tightly attached to the multi-way pipe, and the straight pipe is fixedly connected to the multi-way pipe.

[0012] As a further improvement of the present invention, before the pipe connector is fitted onto the mold in step S11, a fixed connection process is also included to fix the opposite two sides of the second connector to form a pipe connector.

[0013] As a further improvement of the present invention, after processing at least one first through hole smaller than the mold size on the first connecting material in step S1, multiple second through holes are also processed on the inner sidewall of the first through hole, thereby increasing the contact area of ​​the connecting edge when the lower part of the pipe connector is pressed tightly against the connecting edge by the pressing device in step S11.

[0014] As a further improvement of the present invention, the mold includes a working part, a support part and a connecting part integrally arranged from top to bottom. The support part protrudes from the outer peripheral surface of the working part and the connecting part. The specific method of putting the first connecting material on the mold in step S11 is to put the first connecting material on the working part and place it on the support part.

[0015] As a further improvement of the present invention, the specific method for the molding device to press the lower part of the pipe connector tightly against the connection edge in step S11 is as follows: the molding device is sleeved on the working part and placed on the support part.

[0016] As a further improvement of the present invention, the specific method of pressing the lower part of the pipe connector tightly against the connecting edge in step S11 is as follows: the driving member drives the pressing member to press the working part and the supporting part forward. The pressing member has a pressing position and a releasing position. When it is in the pressing position, the left and right sides of any pressing member are attached to the adjacent pressing member.

[0017] As a further improvement of the present invention, before using the fixed connection process to fix the lower part of the pipe connector to the connection edge in step S11, the method further includes: placing the mold sideways on the mold support, the mold support being provided with placement grooves for placing the working part and the connection part so as to rotate the mold while using the fixed connection process.

[0018] The mold support is equipped with positioning marks, and the bottom surface of the connecting part is equipped with several evenly distributed angle marks to adjust the angle when rotating the mold.

[0019] The beneficial effects of the present invention are at least as follows:

[0020] 1. The ability to decompose and unfold the three-dimensional shape of the inflatable support into a planar structure for processing not only simplifies the design process and reduces production difficulty, but also improves material utilization. By adopting a multi-channel pipe processing and fixed connection process, the manual stacking and welding steps are reduced, making the production process more automated and standardized, thereby significantly improving overall production efficiency. Using molds, the openings in the planar material can be erected to form connecting edges, enabling the two layers of connecting material to be welded at the overlapping part, effectively enhancing the tear resistance and tensile strength of the inflatable pipe, and improving the product's durability and safety.

[0021] 2. The supporting arc surface of the support part and the pressing arc surface of the pressing device cooperate with each other to ensure that the workpiece can be stably and evenly stressed during the fixed connection process, thus ensuring the stability and consistency of product quality.

[0027] The technical solution of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0028] Reference Figure 1-5 The present invention proposes an inflatable support connection method. The inflatable support is composed of multiple multi-way pipes 11 and multiple straight pipes 12 connected together. Each multi-way pipe 11 is processed using a multi-way pipe method, and the straight pipes 12 are connected to the multi-way pipes 11 respectively using a fixed connection process.

[0029] The specific steps for processing multi-port pipes are as follows:

[0030] S1. First, flatten the elastic first connecting material 2, and then process at least one first through hole 21 with a size smaller than that of the mold 3 on the first connecting material 2. The number of first through holes 21 is two times the number of pipes in the multi-channel pipe 11.

[0031] S11. The first connecting material 2 is fitted onto the mold 3. The inner wall of the first through hole 21 is squeezed and raised by the mold 3 to form a connecting edge 22. The pipe connector 4 is fitted onto the mold 3 so that the lower part of the pipe connector 4 fits against the outer surface of the connecting edge 22. The lower part of the pipe connector 4 is tightly fitted against the connecting edge 22 by the pressing device 5. The lower part of the pipe connector 4 is fixedly connected to the connecting edge 22 by the fixed connection process.

[0032] S12. The two opposite sides of the first connecting material 2 are fixedly connected by a fixed connection process to form a multi-channel pipe 11.

[0033] The ability to decompose and unfold the three-dimensional shape of the inflatable support into a planar structure for processing not only simplifies the design process and reduces production difficulty, but also improves material utilization. By adopting a multi-channel pipe processing and fixed connection process, the manual stacking and welding steps are reduced, making the production process more automated and standardized, thereby significantly improving overall production efficiency. Using molds, the openings in the planar material can be erected to form connecting edges, enabling the two layers of connecting material to be welded at the overlapping part, effectively enhancing the tear resistance and tensile strength of the inflatable pipe, and improving the product's durability and safety.

[0034] As a further improvement of the present invention, the specific method of the fixed connection process is high-frequency welding, high-temperature heat sealing, or adhesive bonding.

[0035] High-frequency welding utilizes the heat generated by a high-frequency electromagnetic field for rapid, localized welding. This allows for precise positioning of the welding area, significantly reducing the risk of material deformation caused by uneven temperature distribution. It ensures a tight and secure connection between all parts of the inflatable support frame, while also improving production efficiency and product quality stability. Furthermore, high-frequency welding has a small heat-affected zone, better protecting the material's properties.

[0036] High-temperature heat sealing can easily cause distortion and deformation, but this drawback can be effectively overcome by using precision mold pre-positioning and strictly controlling heat sealing parameters to achieve accurate and efficient connection.

[0037] Adhesive bonding enables rapid connection at low or normal temperatures, avoiding the potential hazards of high temperatures. It can also adapt to the connection needs of more types and materials of pipes, enhancing the flexibility and applicability of the process.

[0038] As a further improvement of the present invention, the specific method of connecting the straight pipe 12 to the multi-way pipe 11 by the fixed connection process is as follows: one of the pipes of the multi-way pipe 11 is sleeved on the mold 3, one side of the second connecting material 6 is wrapped around the mold 3 and tightly attached to the multi-way pipe 11, and the second connecting material 6 is fixedly connected to the multi-way pipe 11.

[0039] The use of mold 3 for auxiliary connection greatly simplifies the pipe connection process, reduces the workload of manual operation, and increases the assembly speed, thereby significantly improving production efficiency. The design of the second connecting material 6 allows for adjustment of the number of winding layers and the tightness as needed, and is suitable for connecting straight and multi-way pipes of various specifications and materials, enhancing the versatility and adaptability of the process.

[0040] As a further improvement of the present invention, the specific method of connecting the straight pipe 12 to the multi-way pipe 11 by the fixed connection process is as follows: the two opposite sides of the second connecting material 6 are fixedly connected by the fixed connection process to form the straight pipe 12, one of the pipes of the multi-way pipe 11 is sleeved on the mold 3, the straight pipe 12 is sleeved on the mold 3 and closely attached to the multi-way pipe 11, and the straight pipe 12 is fixedly connected to the multi-way pipe 11.

[0041] The formed straight pipe 12 and multi-way pipe 11 are connected on the mold 3. With the guidance and positioning function of the mold, the accuracy and stability of the connection between the two are ensured, which greatly reduces the installation error. By tightly attaching the straight pipe 12 to the multi-way pipe 11 and fixing it with the assistance of the mold 3, the contact area and connection strength between the two are enhanced, making the inflatable bracket 1 more resistant to pressure changes during use, reducing the risk of air leakage at the connection, and improving the safety and service life of the product.

[0042] It should be noted that because the connecting materials are elastic, the mold is located inside the pipe after connection, but can be removed from the opening.

[0043] As a further improvement of the present invention, before the pipe connector 4 is fitted onto the mold 3 in step S11, a fixed connection process is also used to fix the opposite two sides of the second connector 6 together to form the pipe connector 4.

[0044] By pre-fabricating the second connecting material 6 into pipe connector 4 using a fixed connection process, the structural integrity and robustness of the connector are ensured. This process enhances the mechanical properties of the connector itself, enabling it to withstand greater pressure and tension when subsequently connected to the multi-way pipe 11 or other components, thereby improving the overall structural strength and stability of the inflatable support. Pre-fabricating the second connecting material 6 into pipe connector 4 achieves partial modularization and standardization of the production process, simplifying the on-site assembly process.

[0045] As a further improvement of the present invention, after processing at least one first through hole 21 with a size smaller than that of the mold 3 on the first connecting material 2 in step S1, multiple second through holes are also processed on the inner sidewall of the first through hole 21, thereby increasing the contact area of ​​the connecting edge 22 when the lower part of the pipe connector 4 is pressed tightly against the connecting edge 22 by the pressing device 5 in step S11.

[0046] The presence of multiple second through holes allows the stress on the connecting edge 22 to be distributed more evenly over a larger contact area when it is under pressure, thereby reducing local stress concentration and improving the fatigue resistance and service life of the inflatable bracket under working conditions.

[0047] As a further improvement of the present invention, the mold 3 includes a working part 31, a support part 32 and a connecting part 33 integrally arranged from top to bottom. The support part 32 protrudes from the outer peripheral surface of the working part 31 and the connecting part 33. The upper surface of the support part 32 is provided with a support arc surface 321 for support. The specific method of putting the first connecting material 2 on the mold 3 in step S11 is to put the first connecting material 2 on the working part 31 and place it on the support part 32.

[0048] As a further improvement of the present invention, the specific method of pressing the lower part of the pipe connector 4 tightly against the connecting edge 22 in step S11 is as follows: the pressing part 52 is sleeved on the working part 31 and placed on the support part 32.

[0049] As a further improvement of the present invention, the specific method by which the pressing device 5 presses the lower part of the pipe connector 4 tightly against the connecting edge 22 in step S11 is as follows: the driving member 54 drives the pressing member 53 to press the working part 31 and the supporting part 32 forward. The pressing member 53 has a pressing position and a releasing position. When it is in the pressing position, the left and right sides of any pressing member 53 are attached to the adjacent pressing member 53.

[0050] As a first embodiment of the pressing device 5, the pressing device 5 is a pressing member 52 that can be sleeved on the working part 31. The pressing arc surface 51 is provided on the lower surface of the pressing member 52. The pressing member 52 has a pressing member through hole 521, and the inner sidewall of the pressing member through hole 521 is provided with an annular groove 522.

[0051] As a second embodiment of the molding device 5, the molding device 5 includes at least two pressing members 53 and at least two driving members 54 that are connected one-to-one with the pressing members 53 and are used to drive the corresponding pressing members 53 to press the working part 31 and the support part 32 forward or to move away from the working part 31 and the support part 32 backward. The pressing members 53 have a pressing position and a releasing position. When in the pressing position, the left and right sides of any pressing member 53 are attached to the adjacent pressing members 53. The pressing members 53 are provided with striped grooves 531 on the side near the mold 3.

[0052] During the welding process, a portion of the connecting material melts at the welding point. Therefore, the striped groove 531 can retain a portion of the melted connecting material and cool it, preventing the liquid from being squeezed out directly during the welding process and affecting the welding effect. Furthermore, the striped groove 531 will cause the connecting material to form reinforcing ribs during the welding process, increasing the welding area and further strengthening the bonding force between the connecting materials.

[0053] As a further improvement of the present invention, before using the fixed connection process to fix the lower part of the pipe connector 4 to the connection edge 22 in step S11, the method further includes: placing the mold 3 on the mold support 7, the mold support 7 being provided with a placement groove 71 that can place the working part 31 and the connecting part 33 so that the mold 3 can be rotated while using the fixed connection process.

[0054] The mold support 7 is provided with positioning marks 72, and the bottom surface of the connecting part 33 is provided with several evenly distributed angle marks 73 so that the angle can be adjusted when the mold is rotated.
