Abstract

The utility model relates to a quick-swimming device for swimming in water for human bodies, particularly a pedal propeller quick-swimming device which is used for quickening propulsion. The utility model is realized by adopting the pushing rudder [12] of a front propeller which is fixed on the floating body of the propeller [1] and a rear foot pedal spiral pushing device [2] to achieve the purposes of acceleration and entertainment. The utility model has the advantages of small volume, simple structure, convenient use, facility and low cost. The utility model is an ideal device for swimming, entertainment and body-building in the water for the human bodies, and the utility model is also the ideal device for accelerating under the particular case when people swim.

Description

Foot-operated screw quick-swimming equipment

The utility model is a kind of speed trip device that uses when being used for human body and swimming in the water, and particularly the foot-operated screw quick-swimming equipment that advances fast in water is applicable to the general machining industry.

Known, when the people swims in the water, generally all directly in water, strike, the speed that can travel is too slow, but the people but comes speedup by toe, and the speed of being travelled also adds unhappy, accelerate then to carry inconvenience with hull, the cost height, the enjoyment when also not possessing swimming is used when special type is dived under water with being suitable for.

Pick up speed when goal of the invention of the present utility model is exactly to design a kind of suitable human body at above-mentioned weak point and swims in the water, easy to use, flexible, the quick-swimming equipment that can make the people swim in the water and quicken when swimming under amusement, body-building and the particular case again quickens and the body-building recreation purpose thereby reach.

Invention organization plan of the present utility model is told in detail with reference to accompanying drawing 1.

Organization plan of the present utility model is to adopt to be fixed on self buoyancy aid [a 1] rear treadle spiral thrust unit [2] and to produce motive force, this thrust unit [2] be by step on pedal [3] drive in the rotating shaft [7] fluted disc [4] simultaneously transmitting gear [19] and be fixed on simultaneously with fluted disc [19] that angular wheel [8] engagement in the same rotating shaft [20] drives that screw [11] rotation on angular wheel [9] turning cylinder [10] produces thrust and with being fixed on buoyancy aid [1] preceding preposition airscrew thrust rudder [12] realize jointly; Wherein preposition airscrew thrust rudder [12] is that fluted disc [15] the rotation quick-action fluted disc [16] that has hand to catch in arm [13] the rocking-turn quick-action rotating shaft [14] drives coming about with back thrust unit 2 screws [11] vertical spin oars [18] in the rotating shaft [17] simultaneously, quickens and body-building recreation at water thereby reach human body.The utility model also can adopt multi-stage gear transmission and foot-operated screw thrust unit [2] to adopt full seal structure.

The utility model is a kind of speed trip device that uses when being used for human body and swimming in the water, particularly accelerate the quick-swimming equipment of propelling at water, it is to adopt last front propeller promotion rudder [12] of the buoyancy aid [1] that is fixed on self and rear treadle spiral thrust unit [2] to realize jointly, quicken and amusement thereby reach, it is little, simple in structure, easy to use, flexible that it has a volume, and cost is low, and it is the ideal device that human body swims in the water amusement, body-building and quickens when swimming under specific circumstances.

Accompanying drawing 1 is a structural representation of the present utility model.

Embodiment of the present utility model: with one front propeller thrust can be come about [12] and buoyancy aid [1] that rear screw shaft thrust unit [2] self floats by some standard components, good rotating shaft [7], [20], [10], [17], [14] fluted disc [4], [19], [16], [15] angular wheel [8], [9] and screw [11], [18] and the bearing etc. of combination processing, its monnolithic case is processed as fish shape.Adopt foot-operated screw thrust unit [2] and screw promotion rudder [12] full seal structure to get final product.

Claims

1, a kind of foot-operated propeller quick-swimming equipment that constitutes by buoyancy aid [1] and the rear treadle propeller thrust unit [2] that is fixed on himself, it is characterized in that at the preceding preposition propeller thrust rudder [12] of fixing of buoyancy aid [1] wherein preposition propeller thrust rudder [12] is to drive constituting with propeller [11] vertical spin slurry [18] in the rotating shaft [17] simultaneously by fluted disc [15] on hand arm [13] rotating shaft [14] and then rotary fluted disc [16].

2, foot-operated propeller quick-swimming equipment according to claim 1 is characterized in that its monnolithic case is processed as fish shape.

3, foot-operated propeller quick-swimming equipment according to claim 1 is characterized in that foot-operated propeller tumbler [2] can adopt the step-by-step variable gear transmission.

4, foot-operated propeller quick-swimming equipment according to claim 1 is characterized in that foot-operated propeller thrust unit [2] adopts full seal structure.
