Description
Technical Field
[0001] The present invention relates to the field of rowing boats, and more particularly to a lightweight rowing boat. Background Art
[0002] Rowing is becoming an increasingly popular form of recreation. In addition, rowing has become a very popular competitive sport for both amateurs and professionals. Whether rowing is for recreation or competition, the rowing industry is constantly improving the various components of rowing boats and the equipment used by rowing enthusiasts. The structure of the rudder is also constantly improving. However, in order to increase the functionality of the rowing boat, the structure of the rowing boat and the structure of the rudder are becoming more and more complex, although the functions are becoming more and more complete.
[0003] For example, the rowing boat pedal assembly disclosed in the Chinese patent with publication number CN101549745A is provided with a shoe fixing structure on the pedal piece, and the shoe fixing structure is also provided with a permanent magnet structure. In this way, the pedal is controlled by the shoe fixing structure and the permanent magnet structure, thereby realizing the control of the forward direction of the rowing boat. Although the function of controlling the direction is realized, it also brings an inevitable problem. Due to the large number of structures, the overall weight will increase accordingly, thereby affecting the forward speed of the rowing boat.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention
[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a lightweight rowing boat with a lighter overall hull, which is more portable while ensuring normal functions.
[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a lightweight rowing boat, including a shuttle-shaped hull, the hull is provided with a control cabin, a control mechanism is arranged in the control cabin, the control mechanism includes a pedal assembly, the pedal assembly is connected to a control rope, the control rope is connected to a stern rudder for controlling the direction, the hull is made of carbon fiber material and the hull is filled with foam.
[0007] By adopting the above technical solution, the pedal assembly is connected to the rudder through a control rope. Since the pedal can be made of plastic, its weight is relatively light, and the weight of the control rope is even lighter, so the overall weight of the hull can be effectively reduced. In addition, the hull is made of carbon fiber material. Carbon fiber is a material with very high strength and very light weight. It can not only meet the strength requirements of the hull, but also reduce the weight of the hull. The hull is also filled with foam, which makes the hull a solid structure while reducing the weight of the hull and improving the lightness of the hull. In addition, by controlling the pedal assembly, the control rope drives the rudder to rotate, thereby realizing the steering control of the hull. In this way, while ensuring the normal steering function, the overall weight of the hull is reduced, making the hull lighter and improving its flexibility.
[0008] The present invention is further configured as follows: the pedal assembly includes a support plate fixedly connected in the control cabin, the support plate is rotatably provided with a first pedal and a second pedal, the first pedal is connected to a first control rope, the other end of the first control rope passes through the hull and is connected to the stern rudder, the stern rudder is connected to a second control rope, and the second control rope passes through the hull and is connected to the second pedal.
[0009] By adopting the above technical solution, when the first pedal is stepped on, the first pedal will drive the first control rope to move forward, the first control rope is connected to the tail rudder and drives the tail rudder to rotate, and the rotation of the tail rudder will drive the second control rope to move in the direction opposite to the movement of the first control rope, thereby driving the second pedal to rotate in the direction opposite to the first pedal, thus realizing the linkage effect of the first pedal and the second pedal, that is, the first pedal rotates forward while driving the second pedal to rotate backward, and at the same time controls the tail rudder to rotate to the left or right, thereby realizing the steering of the tail rudder.
[0010] The present invention is further configured as follows: the stern rudder includes a cylindrical mounting groove opened on the upper surface of the hull, a hollow cylindrical mounting box is fixedly arranged in the mounting groove, a rotating hole is opened at the bottom of the mounting box, the rotating hole penetrates the hull downward, a rotating rod is rotatably arranged in the rotating hole, one end of the rotating rod located below the hull is fixedly connected to a steering plate, one end of the rotating rod located in the mounting box is transversely fixedly connected to a control rod, the control rod can rotate horizontally around the rotating axis, and one end of the control rod is connected to a first control rope, and the other end is connected to a second control rope.
[0011] By adopting the above technical solution, the rotating rod can rotate in the rotating hole, and when the rotating rod rotates, the steering plate can be driven to rotate. The rotating rod is driven by the rotation of the control rod, and the linkage effect of the first control rope and the second control rope can drive the control rod to rotate, thereby driving the rotating rod and the steering plate to rotate. In this way, when the steering plate rotates, the boat body is turned under the mutual force between the steering plate and the water flow.
[0012] The present invention is further configured such that: the steering plate is arranged in a trapezoidal shape from top to bottom, being wider at the top and narrower at the bottom; and the edge of the steering plate is arranged to become gradually thinner outwards.
[0013] By adopting the above technical solution, the steering plate mainly plays a steering role in the water. The trapezoidal structure minimizes the water resistance of the steering plate when it rotates, making the steering more flexible. The edges of the steering plate gradually become thinner outwards, which can also reduce the water resistance.
[0014] The present invention is further configured as follows: through holes are opened at both ends of the control rod, the first control rope passes through the through hole and is reversely wound and connected to the tensioning assembly, and the second control rope passes through the through hole and is reversely wound and connected to the tensioning assembly.
[0015] By adopting the above technical solution, a tensioning assembly is connected between the first control rope and the second control rope, and the tensioning assembly is used to adjust the tension of the first control rope and the second control rope. Since the first control rope and the second control rope are in a stretched state for a long time, their tension may sometimes become loose. Therefore, a tensioning assembly is provided to adjust their tension so that the first control rope and the second control rope can be in a tensioned state at all times to ensure the steering sensitivity.
[0016] The present invention is further configured as follows: the tensioning assembly includes a connecting rod fixedly connected to the first control rope, and also includes a connecting pipe fixedly connected to the second control rope, and the connecting rod and the connecting pipe are connected by threads.
[0017] By adopting the above technical solution, the connecting rod and the connecting tube are connected by threads. When the tension of the first control rope and the second control rope needs to be increased, the connecting rod is twisted to move the connecting rod into the connecting tube, thereby tensioning the first control rope and the second control rope.
[0018] The present invention is further configured such that: the tail of the hull is configured to be gradually thinner from front to rear in the longitudinal direction.
[0019] By adopting the above technical solution, the tail of the hull is gradually thinned to imitate the structure of a fish tail. On the one hand, it makes the hull more stable and avoids tilting to the left and right. On the other hand, it makes the whole hull streamlined to reduce water resistance.
[0020] The present invention is further configured such that: a drainage component is provided at the bottom of the control cabin.
[0021] By adopting the above technical solution, when water accumulates in the control cabin, the water can be drained out by opening the drainage component to avoid affecting the use.
[0022] The present invention is further configured as follows: at least four mutually connected hanging holes are opened on the upper surface of the hull, and hanging ropes are wound and connected in the hanging holes.
[0023] By adopting the above technical solution, the hanging rope is connected in the hanging hole, and some emergency items such as life jackets or life buoys can be tied through the hanging rope, so that rescue items can be provided when an emergency occurs.
[0024] The present invention is further configured as follows: handles are provided at both the front and rear ends of the hull for easy holding during transportation, and handrails are provided at both sides of the control cabin.
[0025] By adopting the above technical solution, since the boat body is larger as a whole, handles are provided to facilitate carrying, and handrails are provided on both sides of the control cabin to facilitate the operator to hold on during rowing intervals, thereby enhancing convenience.
[0026] In summary, the present invention has the following beneficial effects:
[0027] First, the pedal assembly controls the transmission of the control rope, and the control rope controls the steering of the stern rudder, thereby controlling the steering of the boat body. On the one hand, it can ensure the normal steering function of the boat body, and on the other hand, it can greatly reduce the overall weight of the boat body, making the boat body lighter;
[0028] Secondly, the hull is filled with foam material, which on the one hand reduces the weight of the hull, and on the other hand improves safety and avoids water leakage in the event of a collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] like Figure 1 and Figure 3 As shown, the stern rudder 6 includes a mounting groove 12 opened on the upper surface of the rear end of the hull 1, the mounting groove 12 is opened in a cylindrical shape and a mounting box 13 is fixedly connected in the mounting groove 12 by glue, the mounting box 13 is set in a hollow cylindrical shape, and a rotation hole 14 is opened at the bottom center of the mounting box 13, the rotation hole 14 is opened downwardly and penetrates through the hull 1, a rotation rod 15 is rotatably set in the rotation hole 14, the upper end of the rotation rod 15 is located in the mounting box 13, the lower end of the rotation rod 15 extends downward from the lower surface of the hull 1, and a steering plate 16 is fixedly connected to the part of the lower end of the rotation rod 15 extending out of the hull 1, and the steering plate 16 is set in a trapezoidal shape from top to bottom, which is wide at the top and narrow at the bottom, and the edge part of the steering plate 16 is The middle is gradually thinned toward the outside, and the rotation of the rotating rod 15 can drive the rotation of the steering plate 16, thereby realizing the steering function of the hull 1; a control rod 17 is fixedly connected to one end of the steering rod located in the installation box 13, and the control rod 17 is horizontally arranged in the installation box 13 and the middle part of the control rod 17 is connected to the rotating rod 15, and the two ends of the control rod 17 are respectively connected to the first control rope 10 and the second control rope 11, so that the first pedal 8 and the second pedal 9 can be relatively rotated, The first control rope 10 and the second control rope 11 can move in opposite directions, thereby driving the two ends of the control rod 17 to rotate, and the rotation of the rotating rod 15 drives the steering plate 16 to rotate, thereby realizing the steering function.
[0037] A tensioning assembly 19 is also provided on the hull 1. Figure 3 As shown, the tensioning assembly 19 is arranged on the side of the pedal assembly 4 away from the rudder 6, through holes 18 are opened at both ends of the control rod 17, the first control rope 10 and the second control rope 11 pass through the through holes 18 at both ends of the control rod 17 respectively and are wound backwards, the first control rope 10 and the second control rope 11 are respectively connected to the tensioning assembly 19, and the tensioning assembly 19 is used to adjust the tensioning degree; the tensioning assembly 19 includes a connecting rod 20 fixedly connected to the first control rope 10, and also includes a connecting pipe 21 fixedly connected to the second control rope 11, the end of the connecting rod 20 is provided with an external thread, the inside of the connecting pipe 21 is provided with an internal thread, the connecting rod 20 and the connecting pipe 21 are connected by the meshing of the internal thread and the external thread, and the depth of the connecting rod 20 screwed into the connecting pipe 21 is different, thereby adjusting the tensioning degree of the first control rope 10 and the second control rope 11.

When the control rod 17 rotates, the rotating shaft drives the steering plate 16 to rotate left, so that the hull 1 turns left. In this way, the hull 1 is controlled to turn by the first pedal 8, the second pedal 9 and the control rope 5, which not only realizes the normal steering function of the hull 1, but also effectively reduces the overall weight of the hull 1, making the hull 1 lighter. In addition, the hull 1 is made of carbon fiber material and is filled with foam in the hull 1, which further reduces the weight of the hull 1. In addition, a non-hollow structure is adopted to improve the safety of the hull 1. Even if a collision occurs, water leakage will not occur, thereby improving safety.
