Description

Technical Field

[0001] This utility model relates to the field of seat technology, specifically to a drum-shaped rubber fender with a telescopic guide sleeve. Background Technology

[0002] Rubber fenders, also known as rubber guards, are installed on docks or ships to absorb the collision energy between ships and docks or between ships when they are moored or approaching shore, protecting the ships and docks from damage.

[0003] Currently, drum-shaped rubber fenders are installed at the dockside during the berthing process of ships. Although the existing drum-shaped rubber fenders have basic fendering functions in actual use, when the ship first comes into contact with the drum-shaped rubber fenders, it will contact the side of the rubber fenders, causing the rubber body to bend. This causes the rubber body to bear most of the bending force, which will significantly shorten the overall service life of the drum-shaped rubber fenders in the long run. Therefore, it is necessary to improve them. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a drum-shaped rubber fender with a telescopic guide sleeve to solve the problem of bending of the rubber body, causing the rubber body to bear most of the bending force.

[0006] Technical solution

[0007] To achieve the above-mentioned objective, this utility model provides the following technical solution: a drum-shaped rubber fender with a telescopic guide sleeve, including an mounting plate, a connecting piece mounted on the mounting plate, a rubber column connected to the connecting piece, a ring connected to the rubber column, a rubber plate connected to the ring, and a No. 2 steel wire rope connected to both sides of the rubber plate, with a pulling structure connected to the other end of the No. 2 steel wire rope.

[0008] Furthermore, the pulling structure includes a fixed box, a strong spring is installed at the bottom of the fixed box, and a movable plate is fixedly connected to the top of the strong spring. The external dimensions of the movable plate match the internal dimensions of the fixed box.

[0009] Furthermore, the pulling structure also includes a first steel wire rope, the bottom end of which is connected to the top end of the movable plate, and a pull ring connected to the top end of the first steel wire rope, the outer surface of which is sleeved with the bottom end of the second steel wire rope.

[0010] Furthermore, there are two fixing boxes, which are symmetrical about the center line of the mounting plate. Each fixing box has a fixing block connected to its side, and the bottom end of the fixing block is fixedly connected to the top end of the mounting plate.

[0011] Furthermore, a fixed pulley is installed at the top of the inside of the fixed box, and the outer surface of the middle part of the fixed pulley is in contact with the outer surface of the No. 1 steel wire rope.

[0012] Furthermore, an industrial spring is installed inside the rubber cylinder, with the bottom end of the industrial spring fixedly connected to the bottom end of the rubber cylinder and the top end of the industrial spring movably connected to the top end of the rubber cylinder.

[0013] Furthermore, a contact block is installed on the outer surface of the rubber sheet, and the contact block is rectangular in shape.

[0014] Furthermore, the connecting piece is provided with a plurality of equidistant rubber sheets, and each of the plurality of equidistant rubber sheets is threadedly sleeved with a threaded rod inside.

[0015] Beneficial effects

[0016] Compared with the prior art, this utility model provides a drum-shaped rubber fender with a telescopic guide sleeve, which has the following advantages:

[0017] 1. When the hull surface contacts the side of the rubber plate, the bending deformation of the rubber cylinder and ring will cause the structure inside one of the fixing boxes to become taut. At the same time, since there is a strong spring at the bottom of the fixing box, the strong spring will pull the No. 1 steel cable downward in order to return to the initial state. In this way, the No. 1 steel cable will drive the three No. 2 steel cables back to the initial position. Under the state of tension and compression, the rubber cylinder, ring and the three No. 2 steel cables will form a dynamic balance, thereby reducing the stress on the rubber cylinder and ring, and thus not affecting the service life of the rubber cylinder and ring. At the same time, under the pull of the No. 1 steel cable and the strong spring, the three No. 2 steel cables will adjust the hull in coordination with the hull body, so that the rubber cylinder and ring are subjected to a radial force that promotes the adjustment.

[0018] 2. The force transmitted from the rubber plate will gradually decrease downward under the action of the rubber cylinder, the ring, and the industrial spring until the rubber cylinder and the industrial spring return to their initial state. At the same time, since the industrial spring and the rubber cylinder are not completely connected, the rubber cylinder and the industrial spring are two separate entities that share the force and work together to cancel out the force, thereby increasing the service life of the industrial spring and the rubber cylinder.

[0026] To more clearly illustrate the overall concept of this utility model, a detailed description is provided below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "a solution," "some solutions," "example," "specific example," or "some examples," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that solution or example is included in at least one solution or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0031] Please see Figures 1-5 This utility model proposes a drum-shaped rubber fender with a telescopic guide sleeve, including a mounting plate 1. During use, a connecting piece 2 is installed on the mounting plate 1, and a rubber column 3 is fixedly connected to the connecting piece 2. The rubber column 3 is made of rubber. Rubber can undergo large deformation when subjected to external force and can quickly return to its original shape when the external force is removed. Therefore, the rubber column 3 made of rubber has many excellent properties. In order to make the connection between the mounting plate 1 and the connecting piece 2 more secure, multiple equidistant rubber pieces 14 are provided on the connecting piece 2. At the same time, a threaded rod 15 is sleeved inside each of the multiple equidistant rubber pieces 14. The setting of the rubber pieces 14 ensures that the threaded rod 15 will not create a gap between the rubber piece 14 and the mounting plate 1 during the tightening process, thereby affecting the tightening effect. Moreover, the bottom end of the threaded rod 15 penetrates the mounting plate 1 and extends into the interior of the mounting plate 1, thereby firmly fixing the mounting plate 1 and the connecting piece 2 together.

[0032] Then, a ring 4 is installed at the top of the rubber column 3, and a rubber plate 5 is installed at the top of the ring 4. A contact block 17 is installed on the outer surface of the rubber plate 5. When the boat approaches the shore, the contact block 17 increases the friction between the outer surface of the hull and the rubber plate 5, thus providing better grip and slowing the boat down. Simultaneously, during the approach process, the hull surface first contacts the outer surfaces of the rubber plate 5 and the contact block 17, and the resulting pressure is transmitted downwards. Since the ring 4 is made of natural rubber, it is compressed to act as a buffer, thus offsetting some of the pressure. As the pressure continues to be transmitted downwards, to dissipate the transmitted force energy, the operator... An industrial spring 16 is installed inside the body 3. The bottom end of the industrial spring 16 is fixedly connected to the bottom end inside the rubber column 3, and the top end of the industrial spring 16 is movably connected to the top end inside the rubber column 3. As the force continues to be transmitted downward, the rubber column 3 will be compressed. When it is compressed to a certain extent, the industrial spring 16 will be under force. At this time, under the action of the industrial spring 16 and the rubber column 3, the downward force will gradually decrease until the rubber column 3 and the industrial spring 16 return to their initial state. At the same time, since the industrial spring 16 and the rubber column 3 are not completely connected together, the rubber column 3 and the industrial spring 16 are two separate entities that share the force and cancel each other out, thereby increasing the service life of the industrial spring 16 and the rubber column 3.

[0033] Meanwhile, during the docking process, the outer surface of the hull will come into contact with the side of the rubber plate 5. At this time, the rubber cylinder 3 and the ring 4 connected to the rubber plate 5 will bend and deform. Over time, this will affect the service life of the rubber cylinder 3 and the ring 4. In order to ensure that the service life of the rubber cylinder 3 and the ring 4 is not affected, the operator installs a fixing box 6 on both sides inside the mounting plate 1. The fixing box 6 has a fixing block 13 installed on its side. The bottom end of the fixing block 13 is fixedly connected to the top end of the mounting plate 1. The setting of the fixing block 13 will make the fixing box 6 more stable and the force more balanced. Then, a strong spring 7 is installed at the bottom inside the fixing box 6. The top end of the strong spring 7 is fixedly connected to a movable plate 8. The external dimensions of the movable plate 8 are as follows. The movable plate 8, matching the internal dimensions of the fixed box 6, limits the movement of the powerful spring 7, preventing it from changing position due to force inside the fixed box 6. A first-order steel wire rope 9 is fixedly connected to the middle of the top of the movable plate 8. A pull ring 10 is installed at the top of the first-order steel wire rope 9, and three second-order steel wire ropes 11 are sleeved on the pull ring 10. The three second-order steel wire ropes 11 are connected to the bottom end of the rubber plate 5. The arrangement of the three second-order steel wire ropes 11 disperses the force, thereby reducing the magnitude of the force. A fixed pulley 12 is installed at the top inside the fixed box 6. The outer surface of the middle part of the fixed pulley 12 contacts the outer surface of the first-order steel wire rope 9. The fixed pulley 12 can only change its running direction, not its force magnitude. A similar structure is also installed in another fixed box 6.

[0034] At this time, when the hull surface contacts the side of the rubber plate 5, the bending deformation of the rubber column 3 and the ring 4 will change the structure set inside one of the fixing boxes 6, making it tighter. At the same time, since a strong spring 7 is set at the bottom inside the fixing box 6, the strong spring 7 will pull the first steel wire rope 9 downward in order to return to the initial state. Thus, the first steel wire rope 9 will drive the three second steel wire ropes 11 to return to the initial position. Under the state of tension and compression, the rubber column 3, the ring 4 and the three second steel wire ropes 11 will form a dynamic balance, thereby reducing the force on the rubber column 3 and the ring 4, and thus not affecting the service life of the rubber column 3 and the ring 4. At the same time, under the pull of the first steel wire rope 9 and the strong spring 7, the three second steel wire ropes 11 will adjust the hull in coordination with the hull body, so that the rubber column 3 and the ring 4 are subjected to a radial force that promotes the adjustment.
