Because the present invention is simple to operate, people who can not swim operate the present invention and experiences the fun of cruising in the water.

Description

The hand triangle wing double paddles for helping swimming

One. technical field

The present invention relates to a kind of aquatic sports apparatus, it adopts the dalta wing buoyancy aid of the floating thing making and settlement of the bubble streamlining of lightweight, can help swimming to cruise when underwater exercise for human body Fu Qishang for sleeping in.

Two. background technology

Season in midsummer, people often play in the water in lake or the swimming pool and relieve summer heat, but crowd good at swimming is difficult to achieve one's goal, the buoying device thing of the floating swimming suit of they or dependence, swimming life-buoy and so on roams, maintains its buoyancy in water at water float, not only required great effort, but also barren, be in constantly among the passive motion state.

Three. summary of the invention

Purpose of the present invention will provide a kind of type hand triangle to float wing twin propellers swimming aid exactly, and it can resemble the swimming life-buoy in water human body floating holder effect, can drift in water as the boat-carrying human body again and travel.

The object of the present invention is achieved like this: device has rocking handle gear train twin propellers driver in this fusiform dalta wing buoyancy aid, and rocking handle is put out the two ends of dalta wing head, this driver mainly revolves oar by a rocking handle gear wheel, axis pinion, two bevel gear wheels, two bevel pinions, two slave connecting rods and " Shang " shape framework is formed; wherein: device has trigger and fork dish on the rocking handle of rocking handle gear wheel; cocking can affect the fork dish, can play the effect that control turns to.And Zai “ Shang " the framework both sides of shape framework are provided with slide rail; effect has slide block in slide rail; and be provided with the axle pendulum at the two ends of base of frame; rocking handle gear wheel and axis pinion are by the gearratio Zai “ Shang that sets thus " engagement formation first order speed change in the shape framework, and the axis pinion is coaxial with framework two bevel gear wheels outward again, and constitutes second level speed change by the bevel pinion of bevel gear wheel and its both sides by the gearratio engagement of setting.To revolve oar coaxial because of bevel pinion and connecting rod, and the fore device of connecting rod is in the slide block of framework two wood side-guides, and its slide block can impel bevel pinion and bevel gear wheel engagement under the effect of a stage clip, can be controlled by the fork dish of rocking handle again.When its slide block of fork dish shift fork, bevel pinion is separated with bevel gear wheel, then install in the axle pendulum at base of frame two ends the rear end that connecting rod revolves oar, install the rocking handle gear twin propellers driver of this tripod shape that constitutes thus, when it is crouched Fu Qishang in water during operational movement by device in the dalta wing buoyancy aid and by the people, both hands are rotation crank forward, can drive its twin propellers and promote current and to overtake manned; When if both hands rotate backward rocking handle, its wing body again can the row sternway of manned back.Pull the trigger on left side or the right side rocking handle during if move ahead, its wing body is with deflection to the left or to the right; If pull the trigger on left side or the right side rocking handle during backward, its wing body can retrodeviate to the right or retrodeviate left.Small and exquisite, simple to operate because of volume of the present invention, can control it equally to people good at swimming and experience the enjoyment of in water, cruising.
