Abstract

The utility model relates to a booster for swimming. The booster for swimming is amusement and sporting equipment on water. Because the efficiency of a propeller is very high, great thrust can be generated. The booster for swimming is characterized in that the propeller is driven to rotate by utilizing pedaling force of legs and feet. Thus, the great thrust is generated. Two cross beams 1, 2 for fixing are arranged at the front end of the booster for swimming. Holes are arranged at both ends of the cross beam. Safety belts pass through the holes and are respectively and firmly tied on a chest and an abdomen. Thus, the safety belts can be fixed to a human body. A pedal 3 is pedaled by the double legs to drive a pair of bevel gears in a rotating shaft 4 of the pedal to rotate. Then, the propeller 5 on a back part is driven to rotate.

Description

The swimming boost motor

The utility model is a kind of aquatic sports, amusement equipment.

Swimming is a kind of activity that everybody enjoys a lot, and especially in hot summer, enjoys a trip to some in swimming pool or rivers,lakes and seas, and promptly reducing temperature of heatstroke prevention is taken exercises again, more can experience enjoyment wherein.The equipment of auxiliary propulsion of being used at present to swim has flippers and electric plating propulsion.Flippers is to be used for increasing the strength of striking, and with raising speed, but the efficient of flippers is also not too high, and the speed of raising is limited.And electronic propeller is owing to cost an arm and a leg, safeguard also complicated, so only in some professional domains such as scientific investigation, Salvage Dives, use.

The purpose of this utility model provide a kind of simple in structure, efficient is very high, and auxiliary swimming advances equipment, and has very high recreational.

The purpose of this utility model is achieved in that the front portion of this swimming boost motor is crossbeam or the surfboard that fixes with human body, link to each other with the rear portion by a montant, the rear portion have one with the perpendicular rotating shaft of montant, the two ends of this rotating shaft are the pedals resemble the bicycle, one bevel gear is arranged in this rotating shaft, this bevel type gear is with another and the passive bevel type gear mutually interlock of montant on same axis, and this passive bevel type gear rear portion connects one section power transmission shaft, and this transmission the tip of the axis connects screw.When moving pedal with two pedals, drive the bevel type gear rotation in the pedal rotating shaft, this bevel type gear drives the driven gear rotation of phase interlock with it, and driven gear drives the screw rotation by power transmission shaft, thereby produces thrust forward.

This swimming boost motor is because employing efficient is very high and be extensive use of the screw driving by modern ship, naval vessels, it is higher than existing flippers efficient, speed is faster, more laborsaving, can not only significantly improve the scope of activities of people in water, also have very high recreational.In addition because its simple in structure, than electronic propeller have cheap, safeguard easily, advantage such as consumes energy not.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is a side view of the present utility model.

Fig. 3 is the cutaway view of running part in this device.

Fig. 4 is the side view of second embodiment.

1. fixed cross beams, 2. fixed cross beams, 3. pedals, 4. drive housings, 5. screws, 6. bevel gears, 7. bevel gears, 8. power transmission shafts among the figure.

In Fig. 1, Fig. 2, its front end has two crossbeam (1), (2) of playing fixation, the two ends of crossbeam are porose, during use safety belt is passed from the hole, lash respectively, boost motor is fixed on the human body at chest and belly, step pedal (3) with both feet, rotate a pair of bevel gear (6), (7) that drive in (4), is driven the screw rotation of afterbody again by power transmission shaft (8), produces thrust forward.

In another embodiment of Fig. 4, the surfing template is made in its front portion, and the swimmer lies prone in the above, because the resistance of its front portion is littler, its pace can be faster.In addition, if its safety belt adopts plastics, the rubber strip of inflation, not natatory people also can enjoy enjoyment wherein.This swimming boost motor also is applicable to diving operation and long-distance swimming (as crossing the river) etc.

Claims

The swimming boost motor, it is characterized in that: the front portion is crossbeam or the surfboard that fixes with human body, link to each other with the rear portion by a montant, its rear portion be one with the perpendicular rotating shaft of montant, the two ends of rotating shaft are the pedals resemble the bicycle, this with rotating shaft that pedal links to each other on a bevel gear is arranged, this bevel type gear and another and montant passive bevel gear interlock mutually on same axis, this passive bevel type gear links to each other with one section power transmission shaft, and the transmission the tip of the axis connects screw.
