Abstract

The utility model relates to a convenient swimming pusher, which is characterized in that the upper ends of both lateral walls of a floating body form a flange along the wall surface, and the flange matches mutually with a floating plate made of polyolefin plastic foam materials. A through hole is formed on the top end surface of the floating plate, and the shape of the through hole matches with the external shape of the end top surface of the floating body. Moreover, one side of the through hole is opened and forms a groove along the inner wall surface of the through hole, and the shape of the groove matches with the shape of the flange. Therefore, the flange and the concave groove can be combined together. Moreover, an electrical switch mechanism is fixed on the floating body.

Description

Convenient swimming pusher

The utility model relates to a kind of convenient type swimming pusher, refers to that especially a kind of last sporter's work that supplies water swims or the propulsion plant of the usefulness of diving under water.

Existing swimming pusher purposes is single, heavy and inconvenience control.

The purpose of this utility model provides a kind of convenient type swimming pusher.Its kickboard can supply water, and upward movable person is prostrate.When but natural floating when static, motor drive, can be advanced into desire whereabouts.Because activity efficiency is promoted, and the wear life of equipments such as institute's oxygen of taking increases, in other words, under same operating period requirement, the oxygen apparatus of taking can alleviate when diving under water.

Another purpose of the present utility model is to provide a kind of convenient type swimming pusher, and wherein kickboard is collapsible, can hitched in the person of using front by flexible belt by power-actuated buoyancy aid, and the formation one is established switch can be for controlling usefulness.

The utility model provides a kind of convenient type swimming pusher, comprise that a buoyancy aid, invests the propulsive mechanism under it, buoyancy aid is for by the made airtight hollow body of the little and firm material of proportion, interior storage power source battery, external form is like only general, front end is the one's water breaks shape, and the buoyancy aid top has the moulding that conforms to the human body thorax; And establish flexible neck band, waistband for binding with the person, be provided with the formed propulsive mechanism of a motor and propeller below the buoyancy aid, except that the propeller entery and delivery port, remainder all forms the one of watertight with buoyancy aid, the buoyancy aid front end is established electric switch, is used for the motor action and controls.

Advantage of the present utility model is, and is simple and light, and the dynamical system good airproof performance is easy to use.

Below in conjunction with embodiment and accompanying drawing the purpose of this utility model, advantage and feature are done further narration.

The buoyancy aid side view that Fig. 1 relates to for the utility model, wherein kickboard unloads;

Fig. 2 loads onto the oblique view of kickboard for buoyancy aid in Fig. 1;

Fig. 3 is the profile along II among Fig. 2-II line, in order to show the engomphosis relation between kickboard and buoyancy aid;

Fig. 4 is the side view that is fixed on the electrical switching mechanism of buoyancy aid front end;

Fig. 5 for by frenulum with buoyancy aid be in the schematic diagram of user front.

The convenient formula swimming pusher that the utility model relates to comprises that an airtight buoyancy aid 10 is can proportion little and material that material is firm makes a hollow body, interior storage required drive source is such as battery (not showing on the figure), buoyancy aid 10 front ends 11 can be bow shape, and in order to one's water breaks, rear end 12 can be stern shape.Similar to user's thorax by two sidewall 13-13 to the end face profile that the front and back end (not shown) is surrounded, in order to usefulness.Buoyancy aid 10 front ends are established two

ring

151a, 151b on 11 tops.

Buoyancy aid is set up a motor 22 for 10 times, is power with the battery, and driving one directly places the propeller 23 at motor rear.Motor 22 has big envelope 21 outward with propeller, constitutes a whole watertight propulsive mechanism 20.Must have the inlet opening 212 except that propeller 23 must leave drainage channel 211 and starch side, remainder all is sealed among the big envelope 21.

On buoyancy aid 10 front bulkheads 11 electric switch is arranged, for example button 14, can control the motor action.

On buoyancy aid 10 two sides 13,, form bead 1301 respectively along sidewall 13 in appropriate position near the top.The kickboard 3 that bead 1301 cooperates polyalkene foaming plastics to make.This kickboard 3 has a bigger surface area, and the one side has a shape and the buoyancy aid 10 top end face profile districts hole 301 of corresponding matching each other, and hole 301 is opened in left side edge, and 301 forward and backward minute leg can be strutted by external force.In addition, on the inwall in this hole 301, as shown in Figure 3, do flutedly 302 about half place of kickboard thickness, its width and the degree of depth cooperate each other with bead 1301.So, when in the hole of the kickboard 3 301 both sides application of forces, strut this hole 301, kickboard 3 can be enclosed within on the position, top of buoyancy aid 10, and, keep kickboard 3 and buoyancy aid 10 to become one, become device shown in Figure 2 by the snapping each other of bead 1301 and groove 302.

Combination form shown in Figure 2 is suitable for swimming with the person.When climbing downwards on kickboard 3 with person's chest, with hand control electrical switching mechanism 4, can start propulsive mechanism 20, promote buoyancy aid, kickboard and advance with the person.When usefulness person's trip switch mechanism 4, promptly switching mechanism 4 itself is pulled and stops.The structure of switching mechanism 4 as shown in Figure 4, it is fixed on the buoyancy aid 10.There are eccentric wheel 401 places of a pivot on buoyancy aid 10 to contact with a known press button 402.Switch lever 403 in addition, on eccentric wheel 401 circumference, two screwed holes arranged, so that can be selected one of them screw-in.Among the figure with pull bar 403 ' shown in the imaginary line, position when swimming, present position.When in the pull bar 403 ' application of force eccentric wheel 401 being rotated, can oppress press button 402 and be in " opening " state with the person.Otherwise, when loosing one's grip, can make eccentric wheel 401 go back to original position by the pullback spring (not shown) that acts on the eccentric wheel 401, electric energy is turn-offed.

When utilizing buoyancy aid 10 to be used as power with person's desire to swim underwater, do not use kickboard 3, on buoyancy aid 10 so kickboard 3 must be pulled down.Simultaneously, also pull bar must be screwed off, screw in solid line position as shown in Figure 4 again with the person.Thereafter, situation is utilized to be fixed on the ring 151a on the buoyancy aid 10 end end faces and to be linked with 15 as shown in Figure 5, buoyancy aid 10 is hung over user's item neck.Utilize waistband 16 and ring 151b, buoyancy aid 10 is tied up to the person's of using waist, and utilize hip band 17a, b to be inserted in usefulness person two thigh hipbone places respectively, the other end ties up to waistband 16 places.So finishing buoyancy aid is the extension program.At this moment, by pull bar 403 being turned to shown in the imaginary line 403 from solid line position shown in Figure 4 with the person " position, and it is stuck on the outstanding block 4041 of the backstay 404 that is fixed on the buoyancy aid 10 keeps motionless.So, hand can discharge, and can keep propulsive mechanism 20 and be rotated further and do not stop, and the user is absorbed in and swims underwater, and this bead in both sides can doublely be done balance plate simultaneously.Just in case propulsive mechanism 20 breaks down when motionless, as long as press the release board of

ring

151a, 151b both sides, can release automatically and be with 15 with the person, taking the lead on the waistband 16 breaks away from human bodies with buoyancy aid 10.Relevant ring be configured to prior art, so will not repeat.

The distribution of power supply, switch, motor is known technology, does not give unnecessary details herein, and battery also can be given charging plug, the convenience of using is arranged at any time and need not patch.Above-mentioned part need seal, and its means also are known technology.
