Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to a liftable human-powered sailboat rudder. Background Art

[0002] As people's living standards continue to improve, sailboats have gradually become one of the favorite water tools. As an important part of a sailboat, the rudder is used to manipulate and control the course of the ship. The tiller of a sailboat is an arm-shaped component installed on the top of the rudder to turn the rudder to maintain and change the course of the sailboat. In the existing sailboat rudder design, when the sailboat is docked, due to the shallow water depth near the shore, a rudder that is too long is easy to run aground, which may cause damage to the bottom of the rudder, and in severe cases, the entire rudder structure will be damaged. There are also liftable rudders in the existing designs, but some are inconvenient to use and some have complex structures.

[0003] For example, the announcement number CN211196579U proposes a liftable sailboat rudder, which includes a steering gear, a rudder blade and a rudder stock. The steering gear is installed at the stern, and the steering gear is equipped with a rudder blade connected by a through-connecting shaft. A connecting shaft is provided above the rudder blade, and the other end of the connecting shaft is connected to the rudder stock. The other end of the rudder stock passes through a groove above the steering gear. An upper fixing groove and a lower fixing groove are respectively provided on both sides of the groove, which are used to be clamped and fixed with a pin on the rudder stock. The utility model has a simple structure and a beautiful appearance, and can be detachably installed at the stern of a sailboat. The rudder can be lifted up parallel to the water surface or lowered down perpendicular to the water surface as needed.

[0004] When the device is in use, the rudder blade is lifted when the sailboat approaches the shore. However, when the waves on the shore surge, the sailboat is driven to shake up and down, thereby driving the lifted rudder blade to shake up and down, causing the rudder blade to rotate up and down around the steering gear, and driving the rudder bar to shake through the connecting shaft, which may cause the pin to escape from the upper fixation and contact the limit of the rudder blade, thereby causing the rudder blade to fall. If the sailboat is in shallow water at this time, the rudder blade may touch the bottom, causing damage to the rudder blade. Therefore, a liftable human-powered sailboat rudder is proposed to solve the above problem. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a liftable human-powered sailboat rudder, which has the advantages of being able to firmly limit the lifted rudder blade and not releasing the limit on the rudder blade due to the shaking of the hull, etc., and solves the problem that when the device is in use, the rudder blade is lifted when the sailboat approaches the shore, but when the waves on the shore surge, the sailboat is driven to shake up and down, thereby driving the lifted rudder blade to shake up and down, causing the rudder blade to rotate up and down around the steering gear, and driving the rudder bar to shake through the connecting shaft, which may cause the pin to disengage from the upper fixation and contact the limit on the rudder blade, thereby causing the rudder blade to fall. If the sailboat is in shallow water at this time, the rudder blade will touch the bottom, causing damage to the rudder blade.

[0007] (II) Technical solution

[0008] The utility model solves the above-mentioned technical problem with the following technical solution: a liftable human-powered sailboat rudder, comprising a steering gear hinged at the stern of the sailboat, a rudder blade extending to its left side hinged inside the steering gear, a rectangular shell fixedly connected to the right side of the steering gear, a connecting rod hinged at the top of the rudder blade, an end of the connecting rod away from the rudder blade hinged to a sliding rod slidably connected to the steering gear and extending into the rectangular shell, a rudder bar assembly extending to the right side of the rectangular shell and slidably connected to the rectangular shell is provided at the right end of the sliding rod, and a limit assembly extending above the rectangular shell and transmitting to the rudder bar assembly is provided inside the rectangular shell.

[0009] The beneficial effects of the utility model are:

[0010] The rudder of the liftable human-powered sailboat is lifted by rotating the limit assembly. Due to the transmission of the limit assembly and the rudder stock assembly, the rudder stock assembly drives the sliding rod to slide rightward in the steering gear, thereby driving the rudder blade to move through the connecting rod, so that the rudder blade rotates clockwise around the hinge between the rudder blade and the steering gear, and the rudder blade can be lifted. The lifted rudder blade can be firmly limited and the limit of the rudder blade will not be released due to the shaking of the hull.

[0011] On the basis of the above technical solution, the present invention can also be improved as follows.

[0012] Further, the rudder stock assembly comprises a driven housing, a bent rudder stock and a waist-shaped hole, the right end of the slide bar is fixedly connected to the driven housing located in the rectangular housing, the right side of the driven housing is fixedly connected to the bent rudder stock extending to the right side of the rectangular housing and slidably connected to the rectangular housing, and the top and bottom of the driven housing are both provided with waist-shaped holes;

[0013] Furthermore, the limit assembly includes a lever and an elliptical cam. The interior of the rectangular shell is rotatably connected to a lever that passes through a waist-shaped hole and extends to the top thereof. The outer side of the lever is fixedly connected to an elliptical cam located in the driven shell. The front and rear sides of the elliptical cam are both provided with planes. The intersection of the curved surface part and the flat surface part on the outer side of the elliptical cam is rounded at the transition point. The curved surface part on the outer side of the elliptical cam contacts the right wall of the inner cavity of the driven shell.

[0014] The beneficial effect of adopting the above-mentioned further scheme is that by rotating the lever, the elliptical cam is driven to rotate in the driven housing, and the rotational motion is converted into linear motion by utilizing the elliptical shape of the elliptical cam and the interaction force between the elliptical cam and the driven housing, so that the driven housing can be driven to move rightward in the rectangular housing, and then the sliding rod is driven to slide rightward in the steering gear, thereby driving the rudder blade to move through the connecting rod, so that the rudder blade rotates clockwise around the hinge between it and the steering gear, and the rudder blade can be lifted until the flat part on the outside of the elliptical cam contacts the right wall of the inner cavity of the driven housing, and then the lever is stopped from being rotated. The flat part on the outside of the elliptical cam can contact the right wall of the inner cavity of the rectangular housing more stably and is not affected by the shaking of the sailboat, so the lifted rudder blade can be securely limited. The intersection of the curved part and the flat part on the outside of the elliptical cam is rounded transitionally treated, so that the elliptical cam is smoother during rotation.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the embodiment, Figure 1-3A liftable man-powered sailboat rudder is provided. The utility model comprises a steering gear 1 hinged to the stern of the sailboat, a rudder blade 2 extending to the left side of the steering gear 1 is hinged inside the steering gear 1, a rectangular shell 3 is fixedly connected to the right side of the steering gear 1, a connecting rod 4 is hinged to the top of the rudder blade 2, and a sliding rod 5 which is slidably connected to the steering gear 1 and extends into the rectangular shell 3 is hinged to the end of the connecting rod 4 away from the rudder blade 2, a rudder bar assembly 6 which extends to the right side of the rectangular shell 3 and is slidably connected to the rectangular shell 3 is provided at the right end of the sliding rod 5, and a limit assembly 7 which extends above the rectangular shell 3 and is transmitted to the rudder bar assembly 6 is provided in the rectangular shell 3;

[0021] The tiller assembly 6 comprises a driven housing 601, a bent tiller 602 and a waist-shaped hole 603. The right end of the slide bar 5 is fixedly connected to the driven housing 601 located in the rectangular housing 3. The right side of the driven housing 601 is fixedly connected to the bent tiller 602 extending to the right side of the rectangular housing 3 and slidably connected to the rectangular housing 3. The top and bottom of the driven housing 601 are both provided with waist-shaped holes 603.

[0022] The limiting assembly 7 includes a lever 701 and an elliptical cam 702. The interior of the rectangular housing 3 is rotatably connected with the lever 701 extending through the waist-shaped hole 603 to the top thereof. The outer side of the lever 701 is fixedly connected with the elliptical cam 702 located in the driven housing 601. The front and rear sides of the elliptical cam 702 are both provided with planes. The intersection of the outer curved surface part and the flat surface part of the elliptical cam 702 is rounded. The outer curved surface part of the elliptical cam 702 contacts the right wall of the inner cavity of the driven housing 601.

[0023] By rotating the lever 701, the elliptical cam 702 is driven to rotate in the driven housing 601. The elliptical shape of the elliptical cam 702 and the interaction force between the elliptical cam 702 and the driven housing 601 are used to convert the rotational motion into a linear motion, so that the driven housing 601 can be driven to move rightward in the rectangular housing 3, and then the sliding rod 5 is driven to slide rightward in the steering gear 1, so that the rudder blade 2 is driven to move through the connecting rod 4, so that the rudder blade 2 rotates clockwise around the hinge between it and the steering gear 1, and the rudder blade 2 can be lifted until the flat part on the outside of the elliptical cam 702 contacts the right wall of the inner cavity of the driven housing 601, and then the rotation of the lever 701 is stopped. The flat part on the outside of the elliptical cam 702 can contact the right wall of the inner cavity of the rectangular housing 3 more stably and is not affected by the shaking of the sailboat, so that the lifted rudder blade 2 can be securely limited. The intersection of the curved surface part and the flat part on the outside of the elliptical cam 702 is rounded transitionally processed, so that the elliptical cam 702 is smoother during rotation.

[0024] Working principle:

[0025] Step 1: By rotating the lever 701, the elliptical cam 702 is driven to rotate in the driven housing 601. The elliptical shape of the elliptical cam 702 and the interaction force between the elliptical cam 702 and the driven housing 601 are used to convert the rotary motion into a linear motion, so that the driven housing 601 can be driven to move rightward in the rectangular housing 3;

[0026] Step 2: The driven housing 601 moves rightward in the rectangular housing 3, and then drives the slide bar 5 to slide rightward in the steering gear 1, thereby driving the rudder blade 2 to move through the connecting rod 4, so that the rudder blade 2 rotates clockwise around the hinge between it and the steering gear 1, and the rudder blade 2 can be lifted until the flat part of the outer side of the elliptical cam 702 contacts the right wall of the inner cavity of the driven housing 601, and then the lever 701 stops rotating;

[0027] Step 3: In the above process, the flat part on the outside of the elliptical cam 702 can contact the right wall of the inner cavity of the rectangular shell 3 more stably and is not affected by the shaking of the sailboat, so the raised rudder blade 2 can be firmly limited. The intersection of the curved surface part and the flat part on the outside of the elliptical cam 702 is made with a rounded transition treatment, so that the elliptical cam 702 is smoother during rotation.
