Description

The swimming propeller

Technical field

The utility model relates to the swimming propeller that has automatic water jetting function and swimming speed-regulating function, can increase substantially existing swimming rate, it can be bent irregular the pedaling of swimmer action force and automatically be converted into draining campaign promotion swimmer, its speed is convenient adjustable simultaneously, thrust direction also can be adjusted arbitrarily, is particularly suitable for using in environment such as swimming, diving.

Background technology

At present, in the known swimming propeller, adopting screw usually is main push mechanism.For example invention and created name is that " swimming propeller ", the patent No. disclose so a kind of device for the Chinese utility model patent of " 93214429.2 ".Existing swimming propeller uses gear or chain speed changer because the employing screw is main push mechanism, and not only complex structure requires the user to stretch according to specific mode march simultaneously.But in life, we need be operable swimming propeller without training, are used for the emergent use of not natatory personnel on the one hand, also can allow natatory personnel save muscle power on the other hand, improve swimming rate simultaneously.But present swimming propeller is because problems such as price, complex structure and needs training can't be fit to such occasion.In addition, existing swimming propeller is owing to mostly adopt the screw propulsion mode, in case bump with the people of other swimming injury accident just takes place easily, and this is its deficiency on the other hand.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provide a kind of simple in structure, cost is low, be not easy to take place injury accident, be operable swimming propeller without training.

The purpose of this utility model is achieved in that the swimming propeller, comprise plunger shaft and be located at the interior piston of plunger shaft, piston is connected with pedal by the connecting rod that stretches out from the plunger shaft rear portion, on the plunger shaft wall, be provided with inside water inlet valve of two openings and the outside water outlet valve of two openings, two water inlet valve are positioned at plunger shaft axis the same side and are positioned at both sides, piston front and back simultaneously, two water outlet valve are positioned at plunger shaft axis opposite side and are positioned at both sides, piston front and back simultaneously, two water inlet valve are communicated with water inlet pipe, the water inlet pipe front opening, rear closure; Two water outlet valve are communicated with outlet pipe, outlet pipe rear aperture, front end sealing.

Described plunger shaft, piston, connecting rod, pedal and water inlet pipe are two covers of symmetry, the shared outlet pipe of four water outlet valve on the two-piston chamber.

Described outlet pipe rear aperture adjustable size; Simultaneously water inlet pipe front opening and outlet pipe rear aperture are towards opposite and towards adjustable usually.

The utility model is worn in human body shirtfront or back, and pin and pedal link together, and bends the action force driven plunger by pedaling of leg and realizes that into draining produces thrust, promotes the people thus and advances.Its advantage is:

1, because song is pedaled motion and can both be produced thrust, and the amplitude that song is pedaled is not required, independently propulsion plant is arranged on every pin.Therefore no matter use which kind of song to pedal action, whether all can use the utility model, use simply, do not require through training.

2, simple in structure, cost is low, produces and sells easily and promotes.

3, be not easy to take place injury accident, safe in utilization.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Referring to Fig. 1, from the figure as can be seen, swimming propeller of the present utility model, its main body is the plunger shaft 1 of symmetrically arranged side by side two same structures and shape, and each plunger shaft 1 outside is a streamlined structure, can alleviate the resistance of water like this, its bosom is a column type, and two is a dome-type.Be respectively equipped with piston 2 in plunger shaft 1, piston 2 is connected with pedal 4 by the connecting rod 3 that stretches out from the plunger shaft rear portion.Pedal 4 is used for being connected with pin, and driven plunger moves, and described connecting rod can have different version with pedal.On plunger shaft 1 wall, be provided with inside water inlet valve 5 of two openings and the outside water outlet valve 6 of two openings, two water inlet valve 5 are positioned at plunger shaft axis the same side (the diagram outside) and are positioned at simultaneously on the dome-type of both sides, piston 2 front and back, and two water outlet valve 6 are positioned at plunger shaft axis opposite side (diagram is inboard) and are positioned at simultaneously on the dome-type of both sides, piston 2 front and back.On each plunger shaft two water inlet valve 5 is communicated with water inlet pipe 7 front openings, rear closure respectively with the water inlet pipe 7 in the outside; Outlet pipe 8 in the middle of four water outlet valve, the 6 shared two-piston chambeies on the two-piston chamber is communicated with four water outlet valve 6 by this outlet pipe 8, outlet pipe 8 rear aperture, front end sealing.

Described outlet pipe rear aperture size and towards all adjustable is because the water inlet pipe front opening is towards general opposite with outlet pipe water outlet direction, so the water inlet pipe front opening is towards also being adjustable.Under the constant situation of inflow, openings of sizes difference, the flow velocity difference of water, consequent thrust difference.Opening is more little, and flow velocity is big more, and thrust is big more; Otherwise opening is big more, and thrust is more little.And the outlet pipe opening different towards, determined different thrust directions, thrust direction is opposite with the outlet pipe opening direction, can adapt to posture and angle of rake the wear mode of people in water thus.

The utility model angle of rake operation principle of swimming:

Piston moves backward when leg is pedaled out, because action of pressure, back water outlet valve is opened, and back water inlet valve is closed; Preceding water inlet valve is opened, and preceding water outlet valve is seen Fig. 3 because negative pressure is closed.Water is entered by preceding water inlet valve, is full of regional A, and the water of area B is got rid of by the back delivery port by the piston extruding, and water (flow) direction as shown by arrows.Piston moves forward when the leg song returns, because action of pressure, preceding water outlet valve is opened, and preceding water inlet valve is closed; Back water inlet valve is opened, and back water outlet valve is seen Fig. 2 because negative pressure is closed.Water is entered by back water inlet valve, is full of area B, and the water of regional A is got rid of by preceding delivery port by the piston extruding, and water (flow) direction as shown by arrows.Motion promptly can produce the solid stream of water that flows to delivery port from water inlet and so forth, and these current are regulated the speed and the direction of current by outlet pipe bore size and Orientation, thereby produce the thrust of different size and Orientations.

Because song is pedaled motion and can both be produced thrust, and the amplitude that song is pedaled is not required, and independently propulsion plant is arranged on every pin.Therefore no matter use which kind of song to pedal action, whether all can use the utility model through training.

The thing that the utility model can be provided with cingulum and so on thereon makes it to wear on human body shirtfront or back, pin links together by thing and the pedal that cingulum and so on is set on the pedal, just can descend water swimming or diving, can increase hydrogymnastic enjoyment, have the utility function that improves trip speed again.
