DETAILED DESCRIPTION

[0023] Embodiment one, by Figures 1-5 Give adjustable resistance swimming training device, including installation zone 1 and two palm webs 5, two palm webs 5 are fixedly connected with connecting band two 4 respectively, two connecting band two 4 are fixed with two connecting pull ropes 2 between installation zone 1, and two connecting pull ropes 2 middle installation have adjustable resistance structure 3, and adjustable resistance structure 3 includes two connecting structures 31 with connecting pull rope 2 connection, and multiple elastic resistance ropes 32 are set up between two connecting structures 31, and every elastic resistance rope 32 is fixed with two U-shaped buckles 33 respectively with two connecting structures 31 connection.

[0024] Specifically, the adjustable resistance structure 3 of two connecting pull ropes 2 installs elastic resistance rope 32, i.e. installs elastic resistance rope 32 between the upper and lower two connecting structures 31, according to the number of installing elastic resistance rope 32 to realize resistance adjustment, installs the external column on installation zone 1, and two palm webs 5 are sleeved into the palm, and the user moves forward until the device is straightened, and then the user's arms begin to imitate the training of butterfly swimming, and in the palm swing process, the connecting pull rope 2 is pulled by the palm web 5, and the elastic resistance rope 32 is stretched under stress to generate resistance, so that the user's swimming training is realized.

[0025] In the embodiment, the connecting structure 31 includes a plurality of connecting blocks 311, a plurality of connecting blocks 311 are connected by rotating structure, and the limiting block 331 at the middle top is fixed with the connecting sleeve 312 and the connecting pull rope 2 fixed connection, the bottom of each connecting block 311 is provided with the installation groove 3112, the front and rear of the installation groove 3112 are provided with the side limiting groove 3111 and the connecting block 311 is penetrated, the front and rear of the U-shaped buckle 33 are fixed with the limiting block 331, the limiting block 331 is matched with the side limiting groove 3111, the U-shaped buckle 33 is inserted into the installation groove 3112 of the connecting block 311, and the two limiting blocks 331 are limited with the two side limiting grooves 3111.

[0026] Specifically, the upper U-shaped buckle 33 of the elastic resistance rope 32 is pinched to close, so that its size is contracted, thereby facilitating insertion into the installation groove 3112 of the middle connecting block 311. The U-shaped buckle 33 is completely inserted into the installation groove 3112, and the two limiting blocks 331 are moved to the positions of the front and rear side limiting grooves 3111, so that the U-shaped buckle 33 rebounds to clamp the limiting blocks 331 into the side limiting grooves 3111.

[0027] In example two, on the basis of example one, the plurality of connecting blocks 311 can be folded and stored through the rotating structure connected to each other. The rotating structure includes a semicircular block 314 and two semicircular ears 313. The semicircular block 314 is inserted between the two semicircular ears 313.
