The key 332 is inserted in the lock hole. The outer wall of the lock hole is provided with a plurality of circular holes. A plurality of pins 333 are provided in the circular hole. The pins 333 are engaged with the inner cavity of the card hole.

[0031] With such arrangement, when the user needs to use the car inflatable cushion 7, the user first needs to place the inflatable cushion 7 under the car chassis 9, and then connect the second connecting ring 11 to the main lock body 31 through the threaded hole 32, so that the inflatable cushion 7 can be fixed on the car chassis 9 when the car encounters a flood, and it is not easy to separate from the car chassis 9. There are two fixing mechanisms 3, which are respectively located on both sides of the inflatable cushion 7, and can fix the diagonally opposite wheel hubs of the car wheel hub 2 respectively, so as to improve the stability between the inflatable cushion 7 and the car body 1. Then the user uses the key 332 to insert the lock hole on the lock core 331. When the key 332 is fully inserted into the lock hole, the pin 333 will be aligned with the circular hole on the outer wall of the lock hole. The user turns the key 332, and the pin 333 is aligned with the circular hole on the outer wall of the lock hole. When the user pulls the main lock body 31, the insertion shaft 334 slides on the insertion slot 6, so that the two main lock bodies 31 gradually move away from each other.

It can be quickly adjusted according to needs, which is more convenient and quick to use, improves the portability of the structure, and reduces the cost of use.

[0032] Optionally, in some embodiments, see Figure 5 and Figure 6 The adjusting assembly 35 includes a clamping rod 351, a first bevel gear 352, a second bevel gear 353, a screw rod 354, a connecting rod 355 and a rotating block 356. The clamping rod 351 is slidably connected in the sleeve 34, one end of the screw rod 354 is rotatably connected to the main lock body 31, and the other end of the screw rod 354 is rotatably connected to the clamping rod 351, and the screw rod 354 is threadedly connected to the clamping rod 351, the first bevel gear 352 is fixedly connected to the screw rod 354, and the connecting rod 355 is rotatably connected to the main lock body 31. On the sleeve 34, the second bevel gear 353 is fixedly connected to one end of the connecting rod 355, and the second bevel gear 353 is meshed with the first bevel gear 352, and the other end of the connecting rod 355 is fixedly connected with the rotating block 356. A limiting groove 5 is provided on the sleeve 34, and a limiting ring 4 is provided on the end of the clamping rod 351 close to the main lock body 31. The limiting ring 4 is slidably connected on the limiting groove 5, and the end of the clamping rod 351 away from the main lock body 31 is bent toward the other clamping rod 351.

[0033] When the user needs to use the inflatable cushion 7, the car wheel hub 2 is located between the two sleeves 34, and the user rotates the rotating block 356, which drives the connecting rod 355 to rotate, and the connecting rod 355 drives the second bevel gear 353 to rotate. Because the first bevel gear 352 and the second bevel gear 353 are meshed and connected with each other, the second bevel gear 353 drives the first bevel gear 352 to rotate, and the first bevel gear 352 drives the screw rod 354 to rotate clockwise. The clamping rod 351, which is threadedly connected to the screw rod 354, moves in the direction away from the main lock body 31 on the limit slot 5 as the screw rod 354 rotates clockwise. The user adjusts the required After the desired length is reached, stop rotating the rotating block 356, and then rotate the key 332, the pin 333 will move in the circular hole and engage with the inner cavity of the card hole. After engaging, the two main lock bodies 31 are locked, so that the clamping rod 351 extends into the automobile wheel hub 2 and is fixed on the automobile wheel hub 2, adapting to vehicle tires of different sizes and models, improving its versatility, and can better fit the vehicle tires, providing a more secure fixing effect, and can be quickly adjusted according to needs. It is more convenient and quick to use, improves the portability of the structure, and reduces the cost of use. The setting of the limit ring 4 on the clamping rod 351 can ensure that the clamping rod 351 will not separate from the sleeve 34, thereby improving the stability of the structure.

[0034] Optionally, in some embodiments, see Figure 1 An inflation tube 8 is provided on one side of the inflatable cushion 7.

[0035] With this arrangement, after the user fixes the fixing mechanism 3, he or she inflates the air cushion 7 from the air pipe 8 through the air inflating device, so that the air cushion 7 floats the car, preventing the car from being submerged in water and causing losses to the user.

[0036] Working principle: When the user needs to use the car inflatable cushion 7, the user first needs to place the inflatable cushion 7 under the car chassis 9, and then thread the second connecting ring 11 to the main lock body 31 through the threaded hole 32. The inflatable cushion 7 can be fixed on the car chassis 9. There are two fixing mechanisms 3, which are respectively located on both sides of the inflatable cushion 7. The wheel hubs 2 diagonally opposite to each other can be fixed respectively to improve the stability between the inflatable cushion 7 and the car body 1. Then the user uses the key 332 to insert the lock hole on the lock cylinder 331. When the key 332 is fully inserted into the lock hole, the pin 333 will be aligned with the circular hole on the outer wall of the lock hole. The user turns the key 332, the pin 333 moves on the circular hole and disengages from the inner cavity on the card hole. The user pulls the main lock body 31, and the insertion shaft 334 slides on the insertion slot 6, so that the two main lock bodies 31 gradually move away from each other, positioning the car wheel hub 2 at two positions. When the second bevel gear 353 is engaged with the first bevel gear 352, the second bevel gear 353 is engaged with the first bevel gear 352, and the first bevel gear 352 drives the screw rod 354 to rotate clockwise, and the clamping rod 351 threadedly connected with the screw rod 354 moves in the direction away from the main lock body 31 on the limit groove 5 as the screw rod 354 rotates clockwise. After the user adjusts the required length, the rotating block 356 is stopped, and the key 332 is rotated again. The pin 333 moves in the circular hole and engages with the inner cavity of the card hole. After engagement, the two main lock bodies 31 are locked, so that the clamping rod 351 extends into the automobile wheel hub 2 and is fixed on the automobile wheel hub 2.

[0037] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
