Description

Technical Field

[0001] This utility model relates to the field of rudder connection technology, specifically a modular quick-release sailboat rudder connection device. Background Technology

[0002] The rudder is a crucial component for controlling the direction of a sailboat. When the helmsman turns the rudder handle, the rudder stick rotates accordingly, causing the rudder blades to oscillate in the water. According to Bernoulli's principle and fluid dynamics, the rudder blades change the velocity and pressure distribution of the surrounding water flow, thereby generating a force perpendicular to the direction of the water flow. This force pushes the stern of the sailboat to deflect, thus changing the sailboat's course.

[0003] In the existing technology, the stern of the hull is fixedly connected to a hinged seat by screws, and the rudder is hinged inside the hinged seat. When the rudder needs to be removed for replacement or repair, all the screws between the rudder and the hinged seat must be unscrewed, or the screws between the hinged seat and the hull must be unscrewed to remove the hinged seat and the rudder as a whole before the rudder can be removed. Removing and installing multiple screws is time-consuming and reduces the efficiency of repairing or replacing the rudder. Therefore, a modular quick-release sailboat rudder connection device is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a modular quick-release sailboat rudder connection device, which has the advantages of allowing for quick disassembly and assembly of the rudder, thereby improving the efficiency of rudder maintenance or replacement. It solves the problem in existing technologies where a hinged seat is fixed to the stern of the hull with screws, and the rudder blade is hinged within the hinged seat. When the rudder needs to be removed for replacement or maintenance, all the screws between the rudder blade and the hinged seat must be unscrewed, or the screws between the hinged seat and the hull must be unscrewed to remove the hinged seat and the rudder as a whole before the rudder can be removed. This process of removing and assembling multiple screws is time-consuming and reduces the efficiency of rudder maintenance or replacement.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A modular quick-release sailboat rudder connection device includes a hull and a rudder. The right side of the rudder blade of the rudder is hinged with mushroom plugs that are symmetrically distributed vertically. The stern of the hull is fixedly connected by bolts to sockets that are symmetrically distributed vertically and adapted to the mushroom plugs. Each socket has a locking core assembly that is slidably connected to it and arranged in a ring array. The opposite side of each locking core assembly is adapted to the mushroom plug. Each socket has an elastic transmission assembly that is rotatably connected to it and drively connected to the locking core assembly. The outer side of each elastic transmission assembly is elastically connected to the inner wall of the socket. Each socket has a drive disc that extends to its left side and is adapted to the mushroom plug. The right side of the drive disc is driven by the elastic transmission assembly through short columnar rods arranged in a ring array.

[0008] The beneficial effects of this utility model are:

[0009] This modular quick-release sailboat rudder connection device allows for the alignment of the mushroom-shaped plugs on the right side of the rudder blade with the sockets and forceful insertion. During this process, the mushroom-shaped plugs contact the locking core assembly, causing the locking core assembly to move to the opposite side. This, in turn, drives the elastic transmission assembly to rotate. When the mushroom-shaped plugs are inserted to a certain depth, the elastic transmission assembly resets under the action of elasticity, and then drives the locking core assembly to move to the opposite side, thus locking the mushroom-shaped plugs inserted into the sockets. The rudder can then be installed at the stern of the hull. By rotating the drive disc, the drive disc drives the elastic transmission assembly to rotate via a short column, which in turn drives the locking core assembly to move to the opposite side, thereby releasing the locking core assembly from the mushroom-shaped plugs. The mushroom-shaped plugs can then be pulled out of the sockets, and the rudder can be removed. This device offers the advantage of quick rudder assembly and disassembly, thereby improving the efficiency of rudder maintenance or replacement.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the locking core assembly includes a wedge-shaped slider and a connecting rod. The socket is provided with wedge-shaped sliders that are slidably connected to it and arranged in a circular array. The opposite side of each wedge-shaped slider is adapted to the mushroom plug. The left side of the opposite end of each wedge-shaped slider is fixedly connected to a connecting rod.

[0012] Furthermore, the elastic transmission component includes a shaped disc, an arc-shaped hole, and a tension spring. The shaped disc is rotatably connected to the inside of each socket. The surface of each shaped disc is provided with an arc-shaped hole arranged in a ring array and movably connected to the connecting rod. Several tension springs connected to the inner wall of the socket are hung on the outer side of the shaped disc.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by aligning the mushroom plugs on the right side of the rudder blade with the sockets and forcefully inserting them, the mushroom plugs contact the wedge sliders, causing the wedge sliders to move to the opposite side. Due to the movable connection between the connecting rod and the arc-shaped hole, the connecting rod drives the shaped disk to rotate, and at the same time, it can pull the tension spring open to cause elastic deformation. When the mushroom plugs are inserted to a certain depth, the tension springs return to their elastic deformation, which in turn drives the shaped disk to reverse. At the same time, through the movable connection between the arc-shaped hole and the connecting rod, the wedge sliders move to the opposite side, thereby locking the mushroom plugs inserted into the sockets, and the rudder can be installed at the stern of the hull.

[0014] Furthermore, each of the drive disks is fixedly connected to the adjacent irregular disks by columnar short rods arranged in a ring array.

[0015] The beneficial effect of adopting the above-mentioned further solution is that by rotating the drive disk, the drive disk drives the irregular disk to rotate through the columnar short rod, and then drives the wedge head slider to move to the opposite side through the movable connection between the arc-shaped hole and the connecting rod, thereby releasing the limiting lock core of the wedge head slider on the mushroom plug, so that the mushroom plug can be pulled out from the socket and the rudder can be removed.

[0016] Furthermore, the outer side of the drive disc is engraved with a full circle of anti-slip texture.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip texture provides sufficient friction during the rotation of the drive disc, preventing slippage. Attached Figure Description

[0024] 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.

[0025] In the embodiments, by Figure 1-5 This invention discloses a modular quick-release sailboat rudder connection device. The device includes a hull 1 and a rudder 2. The right side of the rudder blade of the rudder 2 is hinged with mushroom-shaped plugs 3 arranged symmetrically vertically. The stern of the hull 1 is bolted to sockets 4 arranged symmetrically vertically and adapted to the mushroom plugs 3. Each socket 4 contains a locking core assembly 5 slidably connected to it and arranged in a circular array. The opposite side of each locking core assembly 5 is adapted to the mushroom plugs 3. Each socket 4 contains an elastic transmission assembly 6 rotatably connected to it and drivingly connected to the locking core assembly 5. The outer side of each elastic transmission assembly 6 is elastically connected to the inner wall of the socket 4. Each socket 4 contains a drive disc 7 extending to its left side and adapted to the mushroom plugs 3. The right side of the drive disc 7 is driven by the elastic transmission assembly 6 via short columnar rods 8 arranged in a circular array.

[0026] The locking core assembly 5 includes a wedge head slider 501 and a connecting rod 502. The socket 4 is provided with wedge head sliders 501 that are slidably connected to it and arranged in a ring array. The opposite side of each wedge head slider 501 is adapted to the mushroom plug 3. The left side of the opposite end of each wedge head slider 501 is fixedly connected to the connecting rod 502.

[0027] The elastic transmission component 6 includes a shaped disk 601, an arc-shaped hole 602, and a tension spring 603. The shaped disk 601 is rotatably connected inside the socket 4. The surface of the shaped disk 601 is provided with arc-shaped holes 602 arranged in a ring array and movably connected to the connecting rod 502. Several tension springs 603 connected to the inner wall of the socket 4 are hung on the outer side of the shaped disk 601.

[0028] Align the mushroom plugs 3 on the right side of the rudder blade of the rudder body 2 with the sockets 4 and insert them forcefully. During this process, the mushroom plugs 3 come into contact with the wedge sliders 501, causing the wedge sliders 501 to move to the opposite side. Since the connecting rod 502 is movably connected to the arc-shaped hole 602, the connecting rod 502 drives the shaped disk 601 to rotate. At the same time, the tension spring 603 is pulled open to cause elastic deformation. When the mushroom plugs 3 are inserted to a certain depth, the tension spring 603 returns to its elastic deformation, which in turn drives the shaped disk 601 to reverse. At the same time, the wedge sliders 501 move to the opposite side through the movable connection between the arc-shaped hole 602 and the connecting rod 502, thereby locking the mushroom plugs 3 inserted into the sockets 4. The rudder body 2 can then be installed at the stern of the hull 1.

[0029] Each drive disk 7 is fixedly connected to an adjacent irregular disk 601 by a columnar short rod 8 arranged in a ring array;

[0030] By rotating the drive disk 7, the drive disk 7 drives the irregular disk 601 to rotate through the columnar short rod 8, and then drives the wedge head slider 501 to move to the opposite side through the movable connection between the arc-shaped hole 602 and the connecting rod 502, thereby releasing the limiting lock of the wedge head slider 501 on the mushroom plug 3, so that the mushroom plug 3 can be pulled out from the socket 4 and the rudder body 2 can be removed.

[0031] The outer side of the drive disc 7 is engraved with a full circle of anti-slip texture;

[0032] The anti-slip texture provides sufficient friction during the rotation of the drive disk 7 to prevent slippage.

[0033] Working principle:

[0034] Step 1: Align the mushroom plug 3 on the right side of the rudder blade of the rudder body 2 with the socket 4 and insert it forcefully. During this process, the mushroom plug 3 contacts the wedge slider 501, causing the wedge slider 501 to move to the opposite side. Since the connecting rod 502 is movably connected to the arc-shaped hole 602, the connecting rod 502 drives the irregular disk 601 to rotate, and at the same time, the tension spring 603 can be pulled open to make it elastically deformed.

[0035] Step 2: When the mushroom plug 3 is inserted to a certain depth, the tension spring 603 restores its elastic deformation, which in turn drives the irregular disc 601 to reverse. At the same time, through the movable connection between the arc hole 602 and the connecting rod 502, the wedge head slider 501 is driven to move to the opposite side, thereby locking the mushroom plug 3 inserted into the socket 4, so that the rudder 2 can be installed at the stern of the hull 1.

[0036] Step 3: By rotating the drive disk 7, the drive disk 7 drives the irregular disk 601 to rotate through the columnar short rod 8. Then, through the movable connection between the arc-shaped hole 602 and the connecting rod 502, the wedge head slider 501 moves to the opposite side, thereby releasing the limiting lock of the wedge head slider 501 on the mushroom plug 3. The mushroom plug 3 can then be pulled out from the socket 4, and the rudder body 2 can be removed.
