[0021] In one specific embodiment, such as Figure 4 As shown, the telescopic sheath assembly 3 includes an inner telescopic sheath 4, a middle telescopic sheath 5, and an outer telescopic sheath 6, which are sequentially fitted from the inside out. Their structural dimensions gradually decrease from the inside out to meet telescopic storage requirements. It should be noted that the number of telescopic sheaths in this telescopic sheath assembly 3 can be set according to needs and is not limited to... Figure 4 The quantity shown.
[0022] In a preferred embodiment, the telescopic driving mechanism is a multi-stage telescopic driving rod, one end of which is in transmission connection with the inner wall of the inner telescopic sheath 4, and the other end is in transmission connection with the inner wall of the outer telescopic sheath 6, and each stage telescopic pin is driven to extend or retract layer by layer through the telescopic action of the multi-stage telescopic driving rod.

The driving motor 19 drives the driven gear 24 of the first transmission gear set 20 to rotate, and the driven gear 24 drives the second transmission gear set 21 connected with the driving gear 23 to rotate, and so on. For the specific installation and connection mode, please refer to Figures 5-8As shown, again without further elaboration, the technical solution of the present application can be implemented in the art based on the design idea; in operation, the driving motor 19 drives the first transmission gear set 20, the second transmission gear set 21 and the third transmission gear set 22 arranged in the inner layer telescopic sheath 4, the middle telescopic sheath 5 and the outer layer telescopic sheath 6 in stages, and realizes the contraction or expansion of each telescopic sheath of the telescopic sheath assembly 3 through the step-by-step transmission mode. The telescopic drive mechanism arranged in this way can meet the fixed connection of the side of the inflatable bag with special-shaped structure, meet the scene of the telescopic sheath assembly 3 bending along the length direction and in the same direction as the transmission gear set, and realize the large deformation of the telescopic sheath assembly 3 along the length direction through the rotation meshing of each transmission gear of the transmission gear set.
[0024] As shown in Figure 1 , the fixed sheath 8 includes a connecting plate 9, the connecting plate 9 is provided with a positioning sheath 12 at both ends matched with the telescopic sheath assembly 3, a mounting slot 10 for clamping the sheath 1 is formed between the two positioning sheaths 12, and a clamping slot 13 for inserting the telescopic pin of each stage is arranged in the positioning sheath 12. In operation, the clamping sheath 1 is arranged at the mounting slot 10, and then the telescopic sheath assembly 3 at both ends of the clamping sheath 1 is inserted into the clamping slot 13 in the positioning sheath 12 under the action of the corresponding telescopic drive mechanism, so as to realize the quick butt joint and connection of the clamping sheath 1 and the fixed sheath 8. Among them, the connecting plate 9 is provided with a magnetic pole array 11 on one side of the mounting slot 10, and the connecting body 2 is provided with a magnetic pole array 11 with opposite polarity to the magnetic pole array 11 of the connecting plate 9 on the corresponding side of the connecting plate 9, the magnetic pole array 11 is arranged alternately with N pole and S pole, and the magnetic pole polarity of the connecting body 2 and the connecting plate 9 is one-to-one corresponding, which is used for realizing the non-contact magnetic attraction self-alignment of the connecting body 2 and the connecting plate 9 when the clamping sheath 1 is clamped into the mounting slot 10.
[0025] As shown in Figure 2 and Figure 3 , the magnetic attraction connector includes a second magnetic pole plate 16 arranged on the side of the connecting plate 9 away from the mounting slot 10 and the side of the connecting body 2 away from the mounting slot 10, respectively, and a suction plate 14 attached to one side of the flexible bag body is arranged corresponding to the second magnetic pole plate 16, and a first magnetic pole plate 15 with opposite polarity to the second magnetic pole plate 16 is arranged in the suction plate 14. In operation, the clamping sheath 1 and the corresponding suction plate 14 are connected to the inner and outer sides of one side wall of an inflatable bag, respectively, and then the fixed sheath 8 and the corresponding suction plate 14 are connected to the inner and outer sides of the other side wall of the inflatable bag, respectively, and then the clamping sheath 1 is clamped into the mounting slot 10 of the fixed sheath 8, and then the clamping sheath 1 and the fixed sheath 8 are suctioned and fixed through the telescopic drive mechanism.
[0026] In a preferred embodiment, as shown in Figure 1As shown, the connecting device 100 further comprises a sensing system, which comprises a laser sensor 7 and a pressure sensor. The laser sensor 7 is arranged outside the connecting body 2, and the suction plate 14 is provided with a refractive hole 17 corresponding to the laser sensor 7, and the refractive hole 17 is embedded with a prism to refract the laser into a four-way beam. The four-way laser emission is used to monitor the deformation of the flexible air bag in real time. By comparing the reflection data with the preset model, it can be monitored whether there is leakage or wrinkle in the flexible bag. If the leakage causes the inflatable bag to shrink, the external air pump can be used for inflation to maintain a certain degree of expansion. The pressure sensor is arranged at the end of the inner telescopic sheath 4. When the telescopic sheath assembly 3 is driven by the telescopic driving structure to extend into the clamping groove 13 in the positioning sheath 12, the pressure sensor detects the collision pressure when the telescopic sheath extends into the positioning sheath 12, and the telescopic driving mechanism is triggered to stop, and the clamping sheath 1 and the fixed sheath 8 are fixedly connected.
