DETAILED DESCRIPTION

[0025] The utility model will be further explained below in combination with the drawings and specific embodiments.

[0026] As shown in Figures 2 to 7 Embodiment 1 is a high-stability air bag spring, comprising air tube seats 16 with built-in airways 1 and a plurality of air bags 2 arranged above the air tube seats 16, and air nozzles 8 connected to the airways 1. The airways 1 and the air tube seats 16 extend in the same direction. The air tube seats 16 are connected at the same horizontal plane below the air bags 2 to form the base of the air bag spring. Each air tube seat 16 is provided with an airway 1 extending in the same direction as the corresponding air tube seat. At least one air tube seat 16 is connected to an air bag 2 for inflating and deflating the air bag. The plurality of air bags 2 are connected to the top wall of the corresponding airway 1 along the extension direction of the corresponding air tube seat 16, and the inner cavity of the air bag 2 is connected to the corresponding airway 1. This embodiment takes two air tube seats 16 as an example. The two air tube seats 16 extend along the distribution direction of the air bags 2 and are connected to the air bags 2 along the extension path. The two air tube seats 16 are parallel to each other and spaced apart. The airway 1 of each air tube seat 16 is connected to the inner cavity of the air bag 2 at the position where the corresponding air tube seat is connected to the air bag 2. The two air tube seats 16 are connected together at the same side end to form a common end 17. As shown in Figure 3 There are two common ends 17 in this embodiment. The airway 1 of each air tube seat 16 extends to the corresponding common end 17 to form a connection. The air nozzle 8 is connected to the common end 17 to connect the airways 1 of the air tube seats 16. Each common end 17 is connected to an air nozzle 8.

[0027] The utility model discloses a plurality of air tube seats are combined to form the base of the air bag spring. The contact area of the bottom of the air bag spring is expanded, the support stability of the air bag spring under pressure is improved, and the influence of the massage caused by the swing and tilt of the air bag under pressure is avoided. The two air tube seats are below the air bags and are connected at the same horizontal plane to form the base of the air bag spring. The bottom walls of the two air tube seats after inflation form the bottom surface of the aforementioned base, the contact area of the air bag spring downward is expanded, the support stability is improved, the air bag spring can also maintain good balance under pressure, and the swing and tilt of the air bag under pressure are prevented. The air tube seat connected to the air bag can inflate and deflate the air bag to realize the massage work of the air bag spring. The two common ends are connected to the air nozzles, and the two air nozzles work synchronously to accelerate the inflation and deflation speed of the air bag spring and improve the efficiency.

[0028] Furthermore, two tracheal tube seats 16 are symmetrically positioned below the airbag 2 along its centerline. The top walls of the airways 1 of the two tracheal tube seats 16 are respectively attached to the left and right sides of the bottom wall of the airbag 2. Matching through holes 4 are provided on the contacting top walls of the airways 1 and the bottom walls of the airbag 2, allowing the airways 1 to connect to the inner cavity of the airbag 2. With the two tracheal tube seats symmetrically positioned below the airbag, the airbag is compressed, resulting in balanced force distribution and good stability of the airbag spring, preventing the compressed airbag from swaying or tilting. The top walls of the airways directly adhere to the bottom walls of the airbag, and matching openings are provided on the two contact surfaces of the top walls of the airways and the bottom walls of the airbag, enabling communication between the airways and the airbag. In actual production, the top walls of the airways and the bottom walls of the airbag are continuously sealed together by heat pressing around the perimeter of the openings.

[0029] Furthermore, the airbag 2 is composed of multiple vertically stacked square bladders 3 connected together. Each square bladder 3 is formed by sealing and bonding two layers of square sheets 3-1 around their perimeter. Adjacent square bladders 3 are connected by opening matching vent holes 3-2 on the adjacent two layers of square sheets 3-1 and continuously sealing and bonding them around the perimeter of the vent holes. In this embodiment, the airbag is composed of two square bladders connected together. During operation, the two square bladders of the same airbag inflate and deflate repeatedly, transmitting massage stimulation upwards. The surface of the square sheet corresponding to the top surface of the airbag bulges, and the entire surface of the sheet serves as the massage contact surface, transmitting massage stimulation upwards. The large massage contact surface and the two stacked square bladders can increase the overall inflation height of the airbag, thereby increasing the vertical stroke of the massage contact surface and increasing the massage intensity, further enhancing the massage effect of the airbag spring.

[0030] Furthermore, the tracheal tube seat 16 is formed by sealing and bonding two layers of sheets. The upper sheet has multiple through holes 4 matching the airbags 2 along the distribution direction of the airbags 2. To simplify the production process and improve efficiency, the upper sheets of the two tracheal tube seats 16 are integrally formed on the same upper sheet 5, and the lower sheets of the two tracheal tube seats 16 are integrally formed on the same lower sheet 6. Figure 6 In this embodiment, both the upper and lower sheets are U-shaped. The upper and lower sheets are sealed together by hot-press welding to form two parallel air tube seats 16 and corresponding air passages 1. The sealing can also be achieved by other existing technologies. The upper sheet 5 and the lower sheet 6 form the aforementioned common end 17 at the end of the sheet. The air nozzle 8 is connected to the upper sheet 5 or the lower sheet 6 at the common end 17. As shown in the figure, in this embodiment, the air nozzle is preferably connected to the lower sheet 6.

[0031] In order to facilitate the connection of multiple air bag springs to form a matrix arrangement of air bag distribution, the two long sides of the upper sheet 5 and / or the lower sheet 6 are provided with outwardly extending sheet extension edges 7 at the corresponding through holes 4, and positioning holes 7-1 are formed in the sheet extension edges 7. The two air bag springs can be fixed by the overlapping of the two sheet extension edges, so that the two air bag springs are connected together. When the sheet extension edges are of uniform length, the spacing of the two air bag springs can be controlled by adjusting the overlapping of the two extension edges, so as to achieve the matrix distribution of the air bags at precise intervals. Moreover, the positions of the sheet extension edges and the air outlet holes correspond, and then the connection positions of the sheet extension edges also match the air bags. The sheet extension edges on both sides of the same air bag spring are perpendicular to the air bag distribution direction and symmetrically distributed on the left and right sides, which can also reduce the vibration of the air bag during inflation and deflation. The overlapping of the two sheet extension edges can be achieved by existing ultrasonic welding or hot press welding or other common techniques. When the upper and lower sheets are provided with corresponding sheet extension edges, the two sheets are of equal length and opposite on the same side of the two sheet extension edges, and are overlapped when the upper and lower sheets are connected. The positioning holes can further accurately control the overlapping length of the two sheet extension edges. As long as the positioning holes on the two overlapping sheet extension edges coincide, the overlapping length of the two sheet extension edges can be kept consistent, thereby accurately limiting the spacing distance of the two air bag springs. Adjusting the position of the positioning hole on the sheet extension edge can further adjust the spacing of adjacent air bag springs, thereby changing the distribution matrix of the air bags.

[0032] As shown in Figure 5 and Figure 6 , the two common ends 17 are provided with pull tapes 9 for installation, and the pull tapes 9 are provided with detachable positioning structures 10. Preferably, the pull tapes 9 are elastic bands, and the positioning structures 10 are Velcro or snaps. The positioning structure of the present embodiment uses Velcro.

[0033] When the air bag spring is installed inside the mattress, the pull tape and the positioning structure thereon of the common end can be detachably connected and positioned inside the mattress. The pull tape is an elastic band that can be elastically stretched to adapt to the installation needs, facilitating the installation of the air bag spring. The positioning structure is commonly used Velcro or snaps, which is convenient for disassembly and connection.
