[0051] When the user needs to fix the two plug blocks 3, the user manually pulls out the two plug blocks 3 from the two first slots 2 and inserts them into the two second slots 8 respectively. When the two plug blocks 3 are pulled out, the two plug blocks 3 will pull the two safety belts 7 respectively. When the safety belts 7 are pulled, the safety belts 7 will drive the rotating rod 6 to rotate in the storage slot 5. At the same time, the rotating rod 6 will drive the two transmission rods 10 to rotate in the two first rotation slots 9 respectively. When the two transmission rods 10 rotate, the two transmission rods 10 will pull one end of the two spring springs 11 respectively. The two spring springs 11 are wound up. When the two plug blocks 3 are respectively inserted into the two second slots 8, the two plug blocks 3 will squeeze one end of the two plug rods 13, so that one end of the two plug rods 13 enters the two slide grooves 12 from the two second slots 8, so that the two plug rods 13 compress the two springs 14. When the plug block 3 is completely inserted into the second slot 8, the plug rod 13 is inserted into the jack 4 under the action of the rebound force of the spring 14, and the plug block 3 is fixed in the second slot 8, ensuring that the user can quickly fix the two plug blocks 3;

[0052] When the user needs to release the fixation of the two plug blocks 3, the user manually rotates the two rotating blocks 16 to allow the rotating blocks 16 to rotate in the second rotating groove 15, so that the rotating block 16 squeezes the transmission block 18 through the arc groove 17, and the transmission block 18 drives one end of the plug rod 13 from the insertion hole 4 into the slide groove 12. At the same time, the plug rod 13 will compress the spring 14. At this time, the fixation of the two plug blocks 3 is released, ensuring that the user can quickly release the fixation of the two plug blocks 3.

[0053] Embodiment 3:

[0054] This embodiment provides a high-safety rubber inflatable surfboard with an anti-tripping function. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the insertion rod 13 is inclined, and one end of the transmission block 18 is slidably connected to the slide groove 12.

[0055] Here, it is ensured that one end of the insertion rod 13 can be squeezed by the insertion block 3 , and it is ensured that one end of the transmission block 18 can slide normally in the slide groove 12 .

[0056] Embodiment 4:

[0057] This embodiment provides a high-safety rubber inflatable surfboard with an anti-tripping function. In addition to the technical solutions of the above embodiments, it also has the following technical features. The reset component includes:

[0058] Two first rotating grooves 9 are symmetrically opened on the inner wall of the storage groove 5. Two transmission rods 10 fixed to the rotating rod 6 are rotatably connected in the two first rotating grooves 9. A clockwork spring 11 is arranged on the transmission rod 10, and one end of the clockwork spring 11 is fixed to the transmission rod 10, and the other end of the clockwork spring 11 is fixed to the inner wall of the first rotating groove 9.

[0059] Among them, when the fixation of the two plug blocks 3 is released, the user manually pulls out the two plug blocks 3 from the two second slots 8 respectively, and inserts them into the two first slots 2 respectively. When the plug blocks 3 are inserted into the first slots 2, the two transmission rods 10 will be rotated by the torque of the two clockwork springs 11 respectively, so that the two transmission rods 10 drive the rotating rod 6 to rotate, and the rotating rod 6 drives the safety belt 7 to reset, ensuring that the two safety belts 7 can be automatically reeled up.

[0060] Embodiment 5:

[0061] This embodiment provides a high-safety rubber inflatable surfboard with an anti-tripping function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the plug block 3 is plugged into the second slot 8, and a pull block is fixedly connected to the plug block 3.

[0062] Here, it is ensured that the inserting block 3 can be inserted into the second slot 8 , and it is ensured that the user can move the inserting block 3 by means of the pull block fixed on the inserting block 3 .

[0063] Embodiment 6:

[0064] This embodiment provides a high-safety rubber inflatable surfboard with an anti-tripping function. In addition to the technical solutions of the above embodiments, it also has the following technical features: the safety belt 7 is slidably connected to the storage groove 5, and the safety belt 7 is made of elastic material.

[0065] Herein, it is ensured that the safety belt 7 can slide normally in the storage groove 5 and that the safety belt 7 can be stretched.

[0066] When the user needs to transport an injured person at sea, the user lets the injured person lie on the rubber inflatable surfboard body 1, and then the user manually pulls out the two plug blocks 3 from the two first slots 2, and inserts them into the two second slots 8 around the injured person. When the two plug blocks 3 are pulled out, the two plug blocks 3 will pull the two safety belts 7 respectively. When the safety belts 7 are pulled, the safety belts 7 will drive the rotating rod 6 to rotate in the storage slot 5. At the same time, the rotating rod 6 will drive the two transmission rods 10 to rotate in the two first rotation slots 9 respectively. When the two transmission rods 10 rotate, the two transmission rods 10 will pull the two spring springs 11 respectively. The two spring springs 11 are wound up at one end of the two plug blocks 3, and when the two plug blocks 3 are respectively inserted into the two second slots 8, the two plug blocks 3 will squeeze one end of the two plug rods 13, so that one end of the two plug rods 13 enters the two slide grooves 12 from the two second slots 8, so that the two plug rods 13 compress the two springs 14. When the plug block 3 is completely inserted into the second slot 8, the plug rod 13 is inserted into the jack 4 under the action of the rebound force of the spring 14, and the plug block 3 is fixed in the second slot 8. At this time, the emergency personnel can transport the wounded to ensure that the wounded will not slip off the rubber inflatable surfboard body 1;

[0067] When the user needs to use the rubber inflatable surfboard body 1 for surfing, the user manually rotates the two rotating blocks 16 to rotate the rotating blocks 16 in the second rotating groove 15, so that the rotating block 16 squeezes the transmission block 18 through the arc groove 17, and the transmission block 18 drives one end of the insertion rod 13 from the insertion hole 4 into the slide groove 12. At the same time, the insertion rod 13 will compress the spring 14. At this time, the fixation of the two insertion blocks 3 is released. Then the user manually pulls out the two insertion blocks 3 from the two second slots 8 respectively, and inserts them into the two first slots 2 respectively. When the insertion block 3 is inserted into the first slot 2, the two transmission rods 10 will be rotated by the torque of the two spring springs 11 respectively, so that the two transmission rods 10 drive the rotating rod 6 to rotate, so that the rotating rod 6 drives the safety belt 7 to reset, ensuring that the two safety belts 7 can be automatically reeled up.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
