Abstract

The utility model relates to a swimming appliance, in particular to a swimming propeller capable of accelerating the swimming speed.The utility model aims to provide a swimming propeller, which is simple in structure, positive in effect, convenient and practical.By utilizing the swimming propeller, the swimming speed can be increased significantly only by the pushing force of the water without other energies.The swimming propeller comprises a framework and blades.The blades are arranged on the same side of the framework and the upper tops of the blades are movably connected with the framework.The rotation angle of the blades are within the range of positive 90 degrees to reverse 90 degrees.During the propulsion process, the blades are rotated toward one side.

Description

The swimming propeller

Technical field

The utility model relates to a kind of swimming utensil, particularly a kind of swimming propeller that can help to accelerate swimming rate.

Background technology

At present, the swimming propeller that is used to help to swim, accelerate swimming rate has shortcomings such as DeGrain mostly, so the popularity rate on market is not very high.And present swimming propeller uses inconvenience mostly, has increased the difficulty of operation, in daily life, also is not very practical.This just requires to innovate a kind of swimming propeller with very high practical value easy to use, simple in structure.

Summary of the invention

Goal of the invention of the present utility model is: a kind of simple in structure, convenient and practical, obvious results swimming propeller is provided, does not need only to rely on the thrust of water by other energy again, the speed when swimming is significantly accelerated.

For achieving the above object, the utility model is achieved in that a kind of swimming propeller, and described swimming propeller comprises framework, blade; Blade is mounted on the framework, and all in the same side of framework, the last top of blade is connected with CAD, and blade direction when rotated is identical, in the scope of the slewing area of blade about forward 90 degree are spent to reverse 90, and blade is all to a sideway swivel.This swimming propeller makes full use of the active force that trick imposes on blade and water generates and promotes people's motion, thereby accelerates swimming rate.When staring at action after leg carries out, the blade that is fixed on the swimming propeller on the both feet will be because of the resistance of water, and blade is all closed.Under the situation of blade closure, whole swimming propeller will produce the reaction force to the people, thereby, add the speed that the straightforward man swims in the water.When leg was followed people's mobile moving forward, blade can all be opened because of the active force of water to it again, allows water flow out between the blade, can not produce extra resistance when human body is moved forward and hinder moving ahead of health.The slewing area of blade is controlled in the scope of forward 90 degree to reverse 90 degree, makes blade have only closed and open two states, blade can at will disorderly not change, and produces the resistance that hinders human motion.The operation principle that the swimming propeller is fixed on the both hands is identical with operation principle on being fixed on both feet.The last top and the framework of blade flexibly connect, and design mainly is in the scope of slewing area about forward 90 degree are spent to reverse 90 that can guarantee blade like this.

Such scheme is done further refinement: described swimming propeller also comprises horizontal fine rule, and laterally fine rule is connected on the framework, and is vertical placement with blade.The purpose that is provided with horizontal fine rule on framework mainly is the steadiness that guarantees structure, guarantees that blade can freely do the rotation of forward 90 degree about to the reverse 90 degree scopes on framework, and is unlikely to rotation excessively.Described framework is made up of thin steel bar or other fine strip shape things.In order to guarantee service life of the present utility model, control the quality of whole framework simultaneously, make the utility model convenient and practical, framework is made with thin steel bar or other fine strip shape things.

Be arranged in parallel between described blade and the blade, the distance between blade and the blade approximates the width of every blade.Every width of described blade is roughly the same.Because guarantee that blade is when closure state, can guarantee that water can reach maximum to the reaction force of blade, so, the width of blade is designed to more than or equal to the distance between blade and the blade, the active area that guarantees water reaches maximization, also just makes water to the anti-vector of exerting oneself most of blade with reach maximum.

Distance is roughly the same with the width of blade between the described blade.This is the further improvement that this patent is done, when swimming, after two legs shrink, blade opens, parallel with swimming direction, can not produce any resistance, when two legs stretch, when preparation is advanced, because the resistance of water is closed blade, produce resistance, because the width and the distance between the blade of blade are roughly the same, have so just played the effect of maximum resistance; And then swimming rate is faster.

On the described framework obstruction buckle can be set, hinder the breach that buckle is provided with one 90 degree for the blade rotation.In order to control the uniformity of blade direction of rotation, it is identical making the direction of blade when the active force rotation that is subjected to water, has also guaranteed the maximization of lifting surface area on the other hand, has also guaranteed the maximization of the power that is subjected to.Certainly, because water (flow) direction can be simultaneously to the natural principle of two relative direction streams, this buckle can not need yet.

Fig. 2 is the schematic diagram of the obstruction buckle on the utility model.

The specific embodiment

For making the reader more clearly understand architectural feature of the present utility model, be further elaborated below in conjunction with accompanying drawing the utility model.

As shown in Figure 1, form framework 1 of the present utility model with thin steel bar, respectively establish a thin steel bar all around, four steel bars are formed a rectangle, also are provided with the thin steel bar of the thin steel bar around being parallel in inside, form the form of a 2*3.On thin steel bar, also be provided with the bandage that is used for fixing pin or hand.Also be provided with the horizontal fine rule 3 of a lot of framves on framework 1 on the framework 1, horizontal line fine rule 3 all is arranged in parallel, and, laterally the arrangement of fine rule 3 is vertical with blade 2, blade 2 all has roughly the same width, and also be arranged in parallel, the distance between blade 2 and the blade 2 is less than or equal to the width of blade 2.Blade is that shape is the strip that is of rectangle.Being connected between blade 2 and the framework 1 flexibly connects, and blade 2 can be done on framework 1 in the scope of forward 90 degree to reverse 90 degree and rotate.

As shown in Figure 2, for can being done on framework 1 in the scope of forward 90 degree to reverse 90 degree, rotates in blade 2, and the direction of rotation all is consistent, on framework, be provided with and hinder the obstruction buckle 4 that blade 2 is done 180 degree rotations, the correspondence position both sides that blade 2 is housed on framework 1 all are provided with one and hinder buckle 4, and the blade that provides that is provided with one 90 degree on obstruction buckle 4 is done the breach 41 of 90 degree rotations.
