Description
Technical field
The utility model relates to a kind of physical education equipment, particularly relates to a kind of swim training fin.
Background technology
When carrying out swimming teaching to student, due to the leg muscle limited strength of student and beginner is many can be nervous, the frequency of fetching water reduces gradually, causes student and swim and farly strength will do not had to continue, therefore can reduce the enthusiasm of study, forfeiture interest.Flippers of the prior art can help beginner to fetch water, and improves swimming rate, but due to the area of flippers comparatively large, need to pay more strength with flippers, therefore traditional flippers is not a kind of good beginner's training tool.
Utility model content
In order to solve the above problem existed in background technology, the utility model provides a kind of swim training fin, and this flippers has elastic portion, effectively can save the muscle power of user, extends the swimming distance of beginner, improves the enjoyment of learn swim.
The technical solution of the utility model is as follows:
A kind of swim training fin, comprise flippers body, flippers body comprises foot's fixed part and portion of striking, the foot of swimmer can extend in foot's fixed part fixing, the portion of striking is roomy flippers, it is characterized in that, the both sides in described portion of striking are fixed with servomechanism, servomechanism is the cylinder of strip, one end of cylinder is fixed on the termination in the portion of striking, the other end is fixed on the middle part of foot's fixed part side, servomechanism is positioned at foot's fixed part and portion's intersection of striking has elastic reinforcement portion, portion offers perforate to elastic reinforcement, elastomer is tucked in elastic reinforcement portion by perforate.
Described elastomer is spring, and the two ends of spring have fixing hole, are connected with stay cord between fixing hole.
Strike in the middle part of portion and have depressed part, depressed part has fairshaped border.
The beneficial effects of the utility model are: owing to having the power-assisted of spring, each flippers is struck and is struck laborsaving at least 40% than traditional flippers, thus enable student grow the swimming of distance and not tired, deepening gradually the interest of swimming, is a kind of very effective educational aid.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated
Fig. 1 is the utility model embodiment 1 overall structure schematic diagram;
Fig. 2 is the cross-sectional view of the utility model embodiment 1.
Detailed description of the invention
Illustrate below in conjunction with accompanying drawing and with detailed description of the invention, the utility model to be further described:
Embodiment 1
As shown in Figure 1, a kind of swim training fin, comprises flippers body, flippers body comprises foot's fixed part 10 and portion 20 of striking, and foot's fixed part 10 has the tubular of hollow, and the foot of swimmer can stretch in foot's fixed part 10 fixing, fixed form is prior art, not shown in FIG..Portion 20 of striking is roomy flippers, and middle part has depressed part 21, and depressed part 21 has fairshaped border, water can be moved backward with the fastest speed when striking in the portion of striking 20.
The strike both sides in portion 20 are fixed with servomechanism 30, servomechanism 30 is the cylinder of strip, one end of cylinder is fixed on the termination in the portion of striking 20, the other end is fixed on the middle part of foot's fixed part 10 side, servomechanism 30 is positioned at foot's fixed part 10 and portion 20 intersection of striking has elastic reinforcement portion 31, elastic reinforcement portion 31 offers perforate 32, elastomer is tucked in elastic reinforcement portion 31 by perforate 32, preferably, elastomer can be spring 40, the two ends of spring 40 have fixing hole 41, stay cord 50 is connected with between fixing hole 41, the length of stay cord 50 is connected and fixed hole rear spring 40 with stay cord 50 can tensioning have certain radian and be as the criterion.
Fig. 2 is the side sectional view that spring 40 is tucked into the flippers behind elastic reinforcement portion 31, under the effect of stay cord 50, the bending also tensioning of spring 40, at this time namely can be used as training flippers to use, foot is fixed on water under after foot's fixed part 10 by student, then swimming is started, under the action of the springs 40, can strike waters up and down thus student is swum forward in portion 20 of striking, owing to having the power-assisted of spring, each flippers is struck and is struck laborsaving at least 40% than traditional flippers, thus enable student grow the swimming of distance and not tired, can deepen gradually the interest of swimming, it is a kind of very effective educational aid.
It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
