Abstract

The utility model refers to a swimming exercising bar for swimming beginners using. The swimming exercising bar is characterized in that the swimming exercising bar is a bar-shaped floater of straight shape or being provided with a certain radian, and the rod-shaped floater is formed by plastic material being inflated and provided with a proper length. The advantages are that a user's body can be held moderately by placing horizontally the swimming exercising bar under a chest forearm to make the user easily find the posture and the position closed to the normal swimming, freely exercise the thrash movement and breathe surely and normally. Meanwhile, the swimming exercising bar can be formed to a ring to be used as a traditional lifebuoy when the traditional lifebuoy is required by the user. The exercising apparatus is simple in structure, low in cost and convenient in carrying.

Description

The swimming instruction rod

Affiliated technical field

The utility model relates to a kind of swimming instruction appurtenance, and this apparatus is a kind of swimming instruction rod with buoyancy, can form traditional water wing in case of necessity.

Background technology

Existing traditional water wing, have another name called buoy quoit, the user penetrates the ring-type water wing, be enclosed within the front, safety is convenient, but is unfavorable for that the beginning swimmer practises strokes, this be because the people to penetrate behind the water wing position in water far apart with the actual required people of swimming position in water, make the beginner can not find correct swimming sensation for a long time, in fact swimming beginner can not be swum by the very fast association of this type of water wing, and this type of water wing more function is to be lifesaving.

Summary of the invention

In order to solve the problem that traditional water wing exists, the utility model provides a kind of bar-shaped swimming instruction utensil, this swimming instruction rod can not only help floating function for the beginner provides, more make the user find the posture and the position of swimming easily near normal, and freely practise arm stroke and safety breathing normally, association swims faster.When needing, can also form traditional ring-type water wing.

Design plan of the present utility model is: one has the plastic material of suitable length to inflate the excellent or slight curving arch form rod buoyancy aid of straight type that forms, the cross section is circular or the bar-shaped buoyancy aid of the polygonal plastic inflatable capsule of various geometry, and the corrugated ring surface of some intervals appearance is arranged at length direction.The two ends of barred body have can interconnective hasp, the flexible ring-type tradition water wing that is connected to form.

Good effect of the present utility model is: in water, the user is disposed across it under arm of front, physical contact part is moderately held up, do not resemble the constraint of annular the water wing, neither influence the user and in water, keep correct swimming position and posture, can make it freely put arm stroke to good use again, can also guarantee that user's safety breathes normally, thus can be not only soon but also association's swimming safely.Not only because the utility model but also can form a ring-type, shape such as traditional buoy quoit, so when the user needs, can be relievedly with its usefulness as buoy quoit.This exercise rod is the plastic inflatable capsule, and simple in structure, cost is low, and is easy to carry.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1, first embodiment scheme drawing of the utility model.

Fig. 2, second embodiment scheme drawing.

Fig. 3, the 3rd embodiment scheme drawing.

Fig. 4, the section shape scheme drawing of each embodiment possibility design alternative.

Among the figure: 1. plastic sheeting, 2. admission piece 3. corrugated excellent post surface, 4. hasps.

The specific embodiment

At Fig. 1, among Fig. 2, the utility model embodiment is straight shape or arch pneumatic bar.It is formed through admission piece (2) inflation by plastic film (1).Under the state of nature after the capacity inflation, can there be the possibility of further bending on some corrugated excellent post surfaces (3) spaced apart.

In Fig. 3, the utility model embodiment is an annular solid.When the first, two embodiment head and the tail hasps (4) linked to each other, clava formed ring bodies.Elongate because of outer arch face corrugated surface appropriateness this moment, and the compression of interior arch face corrugated surface makes barred body looped-shaped bending swimming life-buoy, and this moment, whole ringed perimeter still kept radian level and smooth, smoothness.

In Fig. 4, the section display shape of pneumatic bar can be designed to the possible polygon of part.

When the practitioner used first or second embodiment, barred body was pushed down in practitioner's both arms front, and excellent post external waviness shape possesses certain friction force and stops horizontally slipping of barred body.The barred body length direction possesses arc-shaped bend to a certain degree, when practitioner's both arms are pushed down barred body, a side is encircleed at barred body picking-up practitioner's position always relative fixed in radian, thereby guarantees barred body to a certain extent not in welter, the worry that makes first habit person exempt uncontrollable barred body in water.Simultaneously, position and the posture of user in water fixed and held onto to barred body to the buoyancy that the user produces unlike common water wing just, and make practitioner's arm adjoined water surface optionally, and at random in water, swing, experience thereby obtain more natural swimming.

When the practitioner uses the 3rd embodiment, only need ring body is inserted in health, can obtain as the effect of using common water wing.

Claims

1. swimming instruction rod is that a cross section is circular or the polygonal bar-shaped buoyancy aid of various geometry, it is characterized in that the excellent length direction of described exercise becomes excellent column or the little band radian excellent column that overarches.

2. according to right 1 described swimming instruction rod, it is characterized in that described bar-shaped buoyancy aid is the plastic inflatable capsule.

3. according to right 1 described swimming instruction rod, it is characterized in that the corrugated ring surface that described bar-shaped buoyancy aid has some intervals to occur at length direction.

4. according to right 1 described swimming instruction rod, the two ends that it is characterized in that described bar-shaped buoyancy aid have can interconnective hasp.

5. according to right 1 described swimming instruction rod, it is characterized in that described exercise rod is flexible, form ring-type buoyancy aid as traditional water wing.
