Abstract

The utility model discloses a swimming assist device; a kickboard made of light weight materials is tied at the prothorax of the swimmer by a safety belt, and a canular pedestal and a canular fin are longitudinally arranged on the kickboard; the front end of a connecting rod is sleeved and connected with the pedestal which is provided with aligning holes along the radial direction and is fitted with a location pin, and the forepart of the connecting rod is provided with a row of regulating ports which are arrayed from the forepart of the connecting rod to the back part; the corresponding regulating ports are selected to be matched with the aligning holes to be inserted with the location pin, so as to meet the requirements of the swimmers of different height; a hinge mount is arranged at the tail end of the connecting rod, hinge assorted with the hinge mount is positioned at the front end of a sector fish tail, the two sides of the hinge are provided with symmetrical pedals; observed from the axial direction of the hinge, the two pedals and the vertical sector fish tail are integrally arranged in a T shape; when the pedals are trampled by the feet alternately, the pedals and the vertical sector fish tail that are arranged in the T shape take a hinge axis as center to swing left and right, so as to generate thrust like fish swimming in the water. Therefore, the utility model effectively accelerate the speed of swimming, at the same time, the buoyancy generated by the kickboard can ensure the safety of the swimmer.

Description

The swimming assistive device

Affiliated technical field

The utility model relates to a kind of swimming assistive device safely and fast, belongs to the body-building recreation articles for use.

Background technology

At present, known quick swimming assistive device is a flippers, and flippers swings up and down by people's leg and produces thrust, because people's leg mainly is used for trampling, swing up and down so wear flippers imitation dolphin, be very laboriously, cause Leg Cramps easily, incompatibility ordinary people uses.

Summary of the invention

The purpose of this utility model provides the practical fast swimming assistive device of a kind of safety labor-saving, and it can protect swimmer's safety, can improve swimming rate again, and very laborsaving, adapts to the ordinary people and uses.

The technical scheme that its technical problem that solves the utility model adopts is: the kickboard of being made by light material ties up to swimmer's shirtfront by safety belt, kickboard vertically is provided with cannula-like pedestal and fin, connecting rod front end and pedestal socket, pedestal radially is shaped on locating hole, and is furnished with alignment pin, be shaped on one at the connecting rod leading portion and tease and ridicule knothole, adjustment hole is arranged backward by the connecting rod front end, select corresponding adjustment hole to cooperate and insert alignment pin with locating hole on the pedestal, can satisfy different height swimmers' needs, the connecting rod rear end is provided with hinge seat, fan-shaped fish tail front end is provided with the hinge supporting with hinge seat, the hinge both sides are provided with the pedal of symmetry, from the axial observation of hinge, two pedals and vertical fan-shaped fish tail are T font integral layout, when people's bipod is alternately trampled pedal, the pedal and the vertical fan-shaped fish tail that are T font layout will be that the center swings with the hinge axis, produce the same thrust of swimming fish in the water.

The beneficial effects of the utility model are; ergonomics is combined with bionics; make full use of the pedal force of people's leg; the pedal force that people's leg is powerful is converted into the oscillatory forces of fish tail; not only easily laborsaving than traditional swimming mode; and effectively raising swimming rate, the buoyancy of kickboard generation simultaneously can also be protected swimmer's safety.Adapting to very much the ordinary people uses.
