Description

Technical Field

[0001] This utility model relates to the field of rubber boat technology, specifically to a rubber boat with good stability. Background Technology

[0002] There are many types and models of inflatable boats (English terms: NauticExpo, rubber boats, rubber dinghy), including military boats used by the army for river and sea crossing operations; flood control boats used by the armed police for flood control and rescue; motorized boats that are specifically designed for speed; fully manual kayaks; rafting boats for experiencing the fun of whitewater; simple-looking work boats; fishing boats for near-shore fishing, etc.

[0003] Early inflatable boats mostly used simple inflatable structures, with narrow hulls and shallow drafts, making them vulnerable to capsizing in wind, waves, or other external forces. This simple structure could not effectively disperse the impact of wind and waves, causing the inflatable boats to tilt or even capsize easily. For example, common small recreational inflatable boats are generally 1.5-2 meters wide and have a draft of less than 0.5 meters, which will rock violently in slightly larger waves.

[0004] Inflatable boats cannot automatically adjust their weight distribution, which can lead to increased tilting. This not only affects the passenger experience, causing discomfort and panic, but can also cause equipment on board to slip or be damaged due to the tilt.

[0005] To address the aforementioned problems, a rubber boat with good stability is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a stable inflatable boat that solves the problem in the prior art where the inflatable boat cannot automatically adjust its weight distribution, leading to increased tilting.

A second bevel gear is meshed with the outer wall of the first bevel gear.

[0010] By adopting the above technical solution, the rotating rod is limited and controlled by the limiting plate and bolts.

[0011] As a further description of the above technical solution: a lead screw is fixedly connected inside the second bevel gear, and the lead screw is rotatably connected to the inside of the protective box, and a movable seat is threadedly connected to the outer ring of the lead screw.

[0012] By adopting the above technical solution, the second bevel gear rotates to drive the lead screw to rotate.

[0013] As a further description of the above technical solution: both the front and rear ends of the movable seat are slidably connected with guide posts, and the guide posts are fixedly connected to the inner wall of the protective box.

[0020] By adopting the above technical solution, the damping spring is replaced by a sliding column.

[0021] As a further description of the above technical solution: a buffer plate is fixedly connected to one end of the sliding column.

[0022] By adopting the above technical solution, the rubber boat is protected by a buffer plate.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The present invention provides a rubber boat with good stability.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figure 1 The present invention provides a stable rubber boat, comprising a rubber boat 1, a support plate 3 fixedly connected to the top of the rubber boat 1, and protective boxes 2 fixedly connected to the outer walls of the left and right sides of the rubber boat 1.

[0033] Reference Figure 2 The bottom of the protective box 2 is rotatably connected to a rotating shaft 4. A second rope 10 is fixedly connected to the outer wall of the front end of the rotating shaft 4. A second counterweight 11 is fixedly connected to the bottom of the second rope 10. The second rope 10 extends vertically downwards and its bottom is connected to the second counterweight 11. The function of the second counterweight 11 is to exert a certain pulling force on the rotating shaft 4 with the help of the second rope 10 when the inflatable boat rocks due to its own weight. A first rope 5 is fixedly connected to the outer ring of the rear end of the rotating shaft 4. One end of the first rope 5 is fixedly connected to a first counterweight 6. The first counterweight 6 and the second counterweight 11 are connected at the bottom. Magnets can be added to the part, and the first rope 5 and the second rope 10 are placed on the bottom of the water to be used as a boat anchor. The first counterweight 6 and the second counterweight 11 are similar, and the first counterweight 6 generates tension through its weight. The rotation of the rotating shaft 4 plays an adjustment role. The outer ring of the rear end of the rotating shaft 4 is fixedly connected to the limiting plate 7. The limiting plate 7 and the protective box 2 are slidably connected by a pin 8. The function of the pin 8 is that when it is necessary to limit the rotation angle or position of the rotating shaft 4, it can be inserted into a specific position between the limiting plate 7 and the protective box 2, thereby limiting the rotating shaft 4 and preventing it from rotating excessively or arbitrarily.

[0034] Reference Figure 3The protective box 2 is equipped with a protective component, which includes a rotating rod 9. The rotating rod 9 is rotatably connected inside the protective box 2. A limit ring 12 is fixedly connected to the top outer ring of the rotating rod 9. The limit ring 12 and the bolt can limit the rotation range of the rotating rod 9 to a certain extent, preventing it from rotating excessively and affecting the normal operation of the entire protective component. A first bevel gear 13 is fixedly connected to the bottom outer ring of the rotating rod 9. A second bevel gear 14 is meshed with the outer wall of the first bevel gear 13. A lead screw 15 is fixedly connected inside the second bevel gear 14, and the lead screw 15 is rotatably connected to the inside of the protective box 2. The first bevel gear 13 and the second bevel gear 14 mesh with each other. When the rotating rod 9 rotates, the first bevel gear 13 rotates accordingly, which in turn drives the second bevel gear 14, which meshes with it, to rotate, causing the lead screw 15 to rotate. The outer ring of the lead screw 15 is threadedly connected to a movable seat 17. Guide posts 16 are slidably connected through the interior of both ends of the movable seat 17, and the guide posts 16 are fixedly connected to the inner wall of the protective box 2. When the lead screw 15 rotates, due to the transmission action of the thread, the movable seat 17 will move along the axial direction of the lead screw 15. A connecting post 18 is fixedly connected to the opposite side of the movable seat 17, guiding… The function of column 16 is to provide guidance for the movement of movable seat 17, ensuring that movable seat 17 can move smoothly in a predetermined direction without deviation or shaking. One end of connecting column 18 is fixedly connected to push plate 19. When movable seat 17 moves under the drive of lead screw 15, it will drive push plate 19 to move together through connecting column 18. Push plate 19 has a sliding groove 20 inside. A uniformly distributed damping spring 21 is fixedly connected inside push plate 19. Sliding column 22 and sliding groove 20 form a sliding connection relationship. This structure allows the sliding column 22 to slide relative to the sliding groove 20. At the same time, the damping spring 21 provides a certain damping force to slow down the sliding speed of the sliding column 22. One end of the damping spring 21 is fixedly connected to the sliding column 22, and the sliding column 22 is slidably connected to the sliding groove 20. One end of the sliding column 22 is fixedly connected to the buffer plate 23. When the rubber boat is subjected to external impact, the buffer plate 23 can effectively absorb and disperse the impact force through the buffering effect of the damping spring 21 and the sliding column 22, thereby protecting the rubber boat and enhancing its stability.

[0035] Working principle: During the use of the inflatable boat, when it encounters wind and waves that cause the boat to tilt, the counterweights will come into play. If the inflatable boat tilts to one side, the second counterweight 11 on that side will sink due to gravity, driving the rotating shaft 4 to rotate via the second rope 10. When the rotating shaft 4 rotates, the first rope 5 on the outer ring of the rear end will pull the first counterweight 6 on the other side to move. At the same time, the limiting plate 7 will also rotate with the rotating shaft 4. By adjusting the position of the pin 8 on the limiting plate 7, the rotation amplitude of the rotating shaft 4 can be limited, thereby controlling the movement range of the counterweights and achieving a certain degree of balance adjustment. When used, the counterweight can sink to the bottom and act as an anchor. Rotating the rotating rod 9 causes the first bevel gear 13 at the bottom to drive the second bevel gear 14 to rotate, which in turn causes the lead screw 15 to rotate. Since the lead screw 15 is threadedly connected to the moving seat 17, and the moving seat 17 is restricted by the guide post 16 to move only in a straight line, the rotation of the lead screw 15 will cause the moving seat 17 to move. The moving seat 17 drives the push plate 19 to move through the connecting post 18. The sliding post 22 slides in the sliding groove 20. The damping spring 21 plays a buffering role, and the buffer plate 23 can further protect the contact object and protect the rubber boat 1.
