[0030] See also Figure 1-Figure 5 The present application provides an inflatable shaft connection device including a drive assembly 100 and a connection assembly 200.

[0031] See also Figure 1 and 2 The driving assembly 100 includes a bracket 110, a motor 120 and a rotating shaft 130. The rotating shaft 130 is installed on the top of the bracket 110 and rotates through the motor 120. The motor 120 is installed on one side of the bracket 110 and is transmission-connected to the rotating shaft 130.

[0032] In a specific embodiment, the inflatable shaft body 250 and the rectangular head 260 are designed as an integral molding, and a bottom plate 111 and a vertical plate 112 are provided to form a mounting frame to support the entire device.

[0033] In this embodiment, the output end of the motor 120 is fixedly connected to the first pulley 121, and the end of the rotating shaft 130 is provided with a second pulley 133. The first pulley 121 and the second pulley 133 are connected through a synchronous belt transmission. By setting the first pulley 121 and the second pulley 133, the motor 120 is started, and the motor 120 drives the first pulley 121 to rotate. The first pulley 121 drives the second pulley 133 to rotate through the synchronous belt, and the second pulley 133 drives the rotating shaft 130 to rotate, thereby realizing the transmission connection.

[0034] See also Figure 1 、 3 , 4 and 5, the connecting assembly 200 includes a fixed limiting shell 210, a movable limiting shell 220, a positioning member 230, an inflatable shaft body 250 and a rectangular head 260. The fixed limiting shell 210 is fixedly connected to the rotating shaft 130, and one end of the movable limiting shell 220 is slidably set in the rotating shaft 130. The positioning member 230 passes through the rotating shaft 130 and is connected to the movable limiting shell 220. The rectangular head 260 is set at the end of the inflatable shaft body 250, and the rectangular head 260 is located between the fixed limiting shell 210 and the movable limiting shell 220.

[0035] Among them, the rotating shaft 130 is provided with a groove 131, and one end of the movable limiting shell 220 is slidably set in the groove 131. By setting the groove 131, a sliding connection between the movable limiting shell 220 and the rotating shaft 130 is realized. During installation, the movable limiting shell 220 can be temporarily slid into the groove 131.

[0036] Specifically, the positioning member 230 includes a threaded head 231 and a butterfly knob 232. The butterfly knob 232 is fixedly connected to the end of the threaded head 231.

By designing them as rectangular, stable connection and transmission are achieved, ensuring connection and transmission.

[0039] In a specific embodiment, the inflatable shaft body 250 and the rectangular head 260 are integrally formed.

[0040] The working principle of the inflatable shaft connection device is as follows: during use, the motor 120 is driven, the motor 120 drives the first pulley 121 to rotate, the first pulley 121 drives the second pulley 133 to rotate through the synchronous belt, the second pulley 133 drives the rotating shaft 130 to rotate, the rotating shaft 130 drives the two limit shells to rotate, the two limit shells drive the rectangular head 260 and the inflatable shaft body 250 to rotate, and the inflatable shaft body 250 is wound and unwound. When disassembling, first loosen the threaded head 231 and the butterfly knob 232, and then slide the auxiliary block 2 23 drives the movable limiting shell 220 to move, and the movable limiting shell 220 moves into the groove 131, so that the rectangular head 260 and the inflatable shaft body 250 can be disassembled and installed. Similarly, the rectangular head 260 is placed in the fixed limiting shell 210, and then the movable limiting shell 220 is removed and the threaded head 231 and the butterfly knob 232 are screwed on. This greatly facilitates the installation, connection and synchronous rotation of the inflatable shaft body 250 and the rectangular head 260.
