Abstract
The utility model relates to the technical field of racing boats, in particular to a retractable efficient assistant paddle, which comprises a paddle handle, paddle blades, a projection, blade shafts, shaft sleeves, a barrier strip and a riveting piece. The lower end of the paddle handle is the blade shafts, the paddle blades are strip-shaped plates, a plurality of cylindrical shaft sleeves are arranged on one of the longitudinal edges of each paddle blade, the shaft sleeves at the edges of two paddle blades are connected with each other in an interlaced way, and the intersected shaft sleeves are all sleeved on the blade shafts to be rotatably and movably matched with the blade shafts. The hemispherical projection is adhered to the surface of one paddle blade. The barrier strip is a strip-shaped body with an arc strip-type cross section, and is positioned at the side of the blade opposite to the side on which the projection is arranged. Compared with the existing common paddle, the retractable efficient assistant paddle has higher mechanical efficiency.
Description
Technical field
The utility model relates to the Rowing Techniques field, particularly relates to the efficient power-assisted oar of a kind of extendible.
Background technology
The quant that existing racing boat is adopted; Usually all be to constitute by the loom of rod shape and flat blade; In the process of slip racing boat, when blade is in the water and backward during paddling, when the blade face of blade reaches vertical with the paddling direction; Can make ship obtain maximum power, so the sportsman is adjusted to this angle with blade to paddle.The release but each paddles, in the time of need carrying out next time paddling, blade all must leave the water surface and be returned to initial position aloft.And in this process; The sportsman does not often have the angle of time enough adjustment blade; Still blade is resetted forward according to blade face and the perpendicular mode of moving direction; And in this process, air can reduce the speed that quant resets to the resistance that blade produces, and can not overcome or reduce the influence of air resistance to the quant reset speed and have effective measures in the prior art.
The utility model content
The utility model provides a kind of air resistance that can in reseting procedure, reduce for solving the deficiency of prior art, and can obtain the resistance of maximum water in the process of in water, paddling automatically, thereby improves the efficient power-assisted oar of extendible of the mechanical efficiency of quant.
The scheme that solves the utility model technical matters is: the efficient power-assisted oar of extendible is made up of quant handle, blade sheet, convexity, sharf, axle sleeve, blend stop and riveting sheet.Wherein, the lower end of quant handle is to be the sharf of integral body and concentric with the quant handle, and the diameter of sharf is less than the diameter of quant handle.The blade sheet is the plates of strip shape; A plurality of holistic, columnar axle sleeves that are are with it arranged on wherein longitudinal edge of each blade sheet; The interlaced linking of axle sleeve at two blade sheet edges, the clear distance between every adjacent two axle sleeves is greater than the axial length of each axle sleeve.The staggered axle sleeve that is connected all is placed on the sharf and becomes the rotation running-fit to concern with sharf.In the bottom of sharf be with sharf be an integral body and diameter disc shaped riveting sheet greater than the overall diameter of axle sleeve.Be bonded with the hemispheric convexity that a material is a rubber therein on the blade face of a blade sheet.Blend stop is that cross-sectional plane is the bar shape of arc bar shaped, and blend stop is in the reverse side on blade face, protruding place, and the lower end of the upper end of blend stop and quant handle is combined as a whole, and the lower end of blend stop and riveting sheet are combined as a whole.When the dual-side of blend stop contacted with two blade sheets, the line of centers of two blade sheet cross-sectional planes was on same straight line.
The sportsman is in the process of ski-running, and the first blade face that convexity is belonged to is towards the paddling direction of quant in water, when bending to the oars backward; Two blade sheets launch and are in the same plane under the impact of water; This moment, the area of effectively striking of blade sheet reached maximum, and it is maximum that the power that ship obtains also reaches, and left the water surface and in the process that initial position is replied at the blade sheet; Under the effect of blade sheet self inertia and air resistance; Two blade sheets close up automatically, and this moment, air reached minimum to the resistance of blade sheet, and the sportsman can reset quant with the strength of utmost dispatch and minimum and carry out paddling next time.Close up in the process at two blade sheets, because protruding existence is arranged, make between the two blade sheets and can not fit fully, but can leave certain slit, when paddling next time, water can make two blade sheets launch again rapidly to the impact in said slit like this.
Adopt such scheme, compared with prior art, the utlity model has following marked improvement:
Because the utility model can reduce air resistance in reseting procedure, and can obtain the resistance of maximum water in the process of in water, paddling automatically, thereby when saving sportsman's muscle power, improve the degree of utilization of sportsman's muscle power.Therefore the utility model is compared with existing common quant, has higher mechanical efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the A-A section enlarged diagram of Fig. 1.
Among the figure: 1. quant handle 2. blade sheets 3. protruding 4. sharfs, 5. axle sleeves, 6. blend stops, 7. riveting sheets
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
The efficient power-assisted oar of extendible is made up of quant handle 1, blade sheet 2, convexity 3, sharf 4, axle sleeve 5, blend stop 6 and riveting sheet 7.Wherein, the lower end of quant handle 1 is to be the sharf 4 of integral body and concentric with quant handle 1, and the diameter of sharf 4 is less than the diameter of quant handle 1.Blade sheet 2 is the plates of strip shape; A plurality of holistic, columnar axle sleeves 5 that are are with it arranged on wherein longitudinal edge of each blade sheet 2; The axle sleeve 5 interlaced linkings at two blade sheet 2 edges, the clear distance between every adjacent two axle sleeves 5 is greater than the axial length of each axle sleeve 5.The staggered axle sleeve 5 that is connected all is placed on the sharf 4 and with 4 one-tenth rotations of sharf running-fit and concerns.In the bottom of sharf 4 be with sharf 4 be an integral body and diameter disc shaped riveting sheet 7 greater than the overall diameter of axle sleeve 5.Being bonded with a material therein on the blade face of a blade sheet 2 is hemispheric protruding 3 of rubber.Blend stop 6 is that cross-sectional plane is the bar shape of arc bar shaped, and blend stop 6 is in the reverse side on blade face, protruding 3 place, and the lower end of the upper end of blend stop 6 and quant handle 1 is combined as a whole, and the lower end of blend stop 6 and riveting sheet 7 are combined as a whole.When the dual-side of blend stop 6 contacted with two blade sheets 2, the line of centers of two blade sheets, 2 cross-sectional planes was on same straight line.
The sportsman is in the process of ski-running, and the first blade face that convexity 3 is belonged to is towards the paddling direction of quant in water, when bending to the oars backward; Two blade sheets 2 launch and are in the same plane under the impact of water; This moment, blade sheet 2 the area of effectively striking reached maximum, and it is maximum that the power that ship obtains also reaches, and left the water surface and in the process that initial position is replied at blade sheet 2; Under the effect of blade sheet 2 self inertia and air resistance; Two blade sheets 2 close up automatically, and this moment, air reached minimum to the resistance of blade sheet 2, and the sportsman can reset quant with the strength of utmost dispatch and minimum and carry out paddling next time.Close up in the process at two blade sheets 2, because protruding 3 existence is arranged, make between the two blade sheets 2 and can not fit fully, but can leave certain slit, when paddling next time, water can make two blade sheets 2 launch again rapidly to the impact in said slit like this.
