Abstract
The utility model relates to a force resister for swimming training. A main body of the utility model is an even bar-shaped elastic band, one end of the elastic band is provided with a waistband fixed with a human body, and the other end of the elastic band is provided with a connector which can be connected with the edge or the wall of a swimming pool. The connector can be a hook, a sucking disc or a rope. The maximum elastic extension rate of the elastic band is not less than 4, the length of the elastic band is not less than 1/5 of the length of the swimming pool, and the ultimate strength of the elastic band is larger than the advancing force of athletes in water. Elastic bands with different sectional area and length are made through the selection of materials to make the force resister which is suitable for different training occasions and athletes. The force resister for swimming training has the advantages of simple structure, low price, convenient use, etc.
Description
The utility model relates to sports equipment, relates in particular to the equipment that swimming instruction is used.
Be to improve swimmer's achievement, it is very important updating and improving athletic swimming technique, but strengthens its physical efficiency and the motion strength in water also is indispensable means.For this reason, many Sports Goods Production factories both at home and abroad develop and have developed swimming instruction equipment such as " resistance swimming suit ", " mechanical type resistance gauge " in succession, through probationary certificate, though its effect is not satisfactory, how much help the raising of achievement; In addition, these products also exist respectively and cost an arm and a leg or use shortcoming such as inconvenience, so be difficult to popularize.
The purpose of this utility model is, designs and provide a kind of low price, light and handy durable, easy to use, respond well swimming instruction resistance gauge, and to enlarge its scope of application, large tracts of land improves swimmer's achievement.
For achieving the above object, the utility model adopts following design:
This swimming instruction is a uniform bar shaped elastic webbing with the main body of resistance gauge, and the one end is provided with the waistband that can fix with human body, and its other end is connected to the coupling that can join with swimming pool edge or pool wall; Described bar shaped elastic webbing, its maximum flexibility percentage elongation is not less than 4, and the length of elastic webbing approximates the quotient of the maximum flexibility percentage elongation of swimming pool length and elastic webbing, and its ultimate strength should be greater than the thrust of sportsman in water; Described coupling be hook, also can be sucker, also can be rope.
For more clearly explaining design of the present utility model and advantage thereof, as follows with description of drawings in conjunction with the embodiments now:
Fig. 1 is the structural representation of swimming instruction of the present utility model with resistance gauge.
When using this swimming instruction to use resistance gauge, only need coupling 3 is connected on pool side, pool wall or the diving tower, waistband 2 is pricked at waist, when sportsman's entry and forward travel distance reached the length of elastic webbing 1, elastic webbing 1 produced the pulling force of back power at once, and this power F=kS Δ L/L (wherein, k is a coefficient of elasticity, S is the elastic webbing sectional area, and L is the elastic webbing raw footage, and Δ L is an elastic webbing deformation spread length).This shows, this resistance F is directly proportional with Δ L, its maximum is about 5kS, for the stroke that adapts to each athletic physical situation, employing, and training with each species diversity such as swimming pool length, can select the elastic webbing of different materials, the sectional area and the length of elastic webbing, to satisfy the needs that have nothing in common with each other.
Because this resistance gauge is simple in structure, the system valency is cheap, easy to use, will help applying and help to improve Swimming Achievements.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
