Description

Technical Field

[0001] The utility model relates to the technical field of swimming resistance training, in particular to a swimming technique resistance training device. Background Art

[0002] Swimming resistance is the force acting in the opposite direction of the human body's movement in water, mainly friction resistance, shape resistance, wave resistance, etc. When a human body moves in water, the water molecules at the front end are squeezed and flow quickly around the human body to the back end of the human body, and the water flow separates. In this way, the pressure at the front end of the human body is large, while the pressure at the back end is small. The resistance caused by the pressure difference between the front and back ends is called shape resistance; the water waves caused by the human body in swimming are also a resistance to forward movement. This resistance formed by destroying the balance of water is called wave resistance; when a person moves forward in water, the human body rubs against the water molecules in the adjacent water layer, and the force generated by this phenomenon is called friction resistance. The size of these three resistances is closely related to the shape of the human body and is proportional to the projected cross-section of the human body in the direction of the water flow; the same object (except for the sphere) will produce different projected cross-sections due to the use of different angles of propulsion, and the resistance it encounters is also different. Therefore, reasonably increasing the projection area of ​​the swimmer and adjusting the angle of the projection cross-section can increase the swimming resistance, thereby improving the swimmer's swimming skills during swimming training.

[0003] The existing patent (application number: CN202223540328.1) discloses a swimming technique resistance trainer, including a black ribbon, a slide and a soft sponge, a sleeve device is provided at the lower end of the black ribbon, the sleeve device is sleeved at the inner position of the slide, a waist belt is provided at the left and right ends of the slide, an elastic band is provided at the inner position of the waist belt, and the elastic band is sleeved at the inner position of the soft sponge; when the trainer is training, when changing direction, the sleeve device can be rotated by angle through the slide, and the angle rotation rotates with the body, so that the angle adjustment of the resistance parachute can be more convenient during training, a soft sponge is provided at the inner position of the waist belt, the soft sponge is sleeved at the outer wall position of the elastic band, the elastic band is sleeved on the waist through the elastic effect, and then the soft sponge is attached to the front end of the body, so that comfort can be increased during training. However, the above patent technology is not convenient for adjusting the number and weight of the resistance parachute, so it is impossible to change the resistance generated by the device, and it cannot be applied to different trainers. Therefore, the present patent application provides a swimming technique resistance training device to solve the problems raised in the above-mentioned background technology. Utility Model Content
