Abstract

The utility model discloses a protecting device chiefly for learning swimming and is composed of foam plastic ring, a liner sleeve, a rope and a sleeve pipe. When the protecting device is used, two arms of the person pass through an adjustable ring combined by the sleeve pipe to be stooped under armpits and then the person can learn to swim. The user can learn to swim by himself in deep water area without the protection of others. The life safety of the swimmer can also be reliably ensured.

Description

Protector for learning swimming

A kind of protective device that does not need protection of others and learn to swim.

As everyone knows: existing ring shape lifebuoy can only be sought help from for not natatory people and emerge, and can not help association's swimming.

The utility model mainly is at not natatory people, and does not have good shallow water place and protection people, can oneself learn swimming in the profundal zone, and guarantee swimmer's life security reliably.

The utility model constitutes with buoyancy circle (1), lining (2), rope (3) and sleeve pipe (4); buoyancy circle (1) is as Source for buoyancy; making the outer ring is that Long Circle, inner ring are for circular; cross sectional shape is a Long Circle; inner ring is eccentric in the planform of outer ring one side; and opening four through holes near centre of form axle X-X both sides; four linings (2) embed respectively in four holes; play protection and strengthen buoyancy circle (1) with vandal-proof effect; each end passed four bush hole d more respectively after two ropes (3) respectively passed two sleeve pipes (4) circle synthesis, coupled together then.(knotting)

During use, people's two arms respectively pass in the circle that sleeve pipe (4) synthesized, and are stuck in the oxter, and head places the inner ring of buoyancy circle (1), because the connection (knotting) of rope (3) can make the synthetic circle of sleeve pipe (4) increase arbitrarily and dwindle.So tighter with cooperating of arm when dwindling, head is upwards raised thereupon, otherwise head is to sinking.Just during learning swim, circle can be dwindled, head is raised, the buoyancy that produces by buoyancy circle (1) can float head, being that four limbs are motionless also can emerge head, the buoyancy that is produced when four limbs move under water can break away from buoyancy that buoyancy circle (1) produces and learn swim, study is during mid-term, circle can be amplified, head just sinks, and at this moment head will emerge fully, just need to produce buoyancy by quadruped locomotion, when quadruped locomotion is inharmonious, head will sink down in half, and at this moment hand can be held buoyancy circle (1) with the way up holder.Guarantee swimmer's life security reliably, reached the purpose of association's swimming.

The position of sleeve pipe (4) is by four hole decisions in the buoyancy circle (1), four holes are positioned at centre of form axle X-X both sides, make human body act on the gravity application point on the sleeve pipe (4), the buoyancy point that produces with buoyancy circle (1) is in close positions, then buoyancy circle (1) bigger angle of unlikely inclination when being subjected to human body gravity.

Fig. 1, Fig. 2 are structure charts of the present utility model.

User mode figure when Fig. 3 is learn swim.

Major part of the present utility model---buoyancy circle (1) adopts the manufacturing of foam plastic foaming moulding process, also can make air tyre shape structure with plastic sheeting or rubber.Lining (2) adopts the Shooting Technique manufacturing.The equal buyable material of other part worker a little forms, and is simple in structure, is convenient to make.

The utility model is mainly used in the usefulness of learn swim, also can be enclosed within on the waist usefulness as common lifebuoy.

Claims

1, a kind ofly be mainly used in the protective device that learning swim is used, it is characterized in that passing sleeve pipe (4) with rope (3), pass the bush hole d in the buoyancy circle (1) behind the circle synthesis again after two ends be connected.

2,, it is characterized in that bush hole d is positioned at the centre of form axle X-X both sides layout of buoyancy circle (1) by the described buoyancy circle of claim 1 (1).

3, by the described buoyancy circle of claim 1 (1), the outer ring that it is characterized in that buoyancy circle (1) is a Long Circle, and inner ring is circular, and inner ring is eccentric in a side of outer ring.
