Description

Technical Field

[0001] This utility model relates to the field of safety equipment, and in particular to a floating hull railing that is easy to assemble quickly. Background Technology

[0002] In ship navigation and maritime operations, floating railings, as crucial facilities for ensuring personnel safety, face numerous technical challenges. The humid marine environment, with sea breezes carrying high levels of salt, easily corrodes railings. Traditional railings lack convenient replacement methods; once corrosion occurs, disassembly and replacement require significant time and manpower, resulting in high maintenance costs. Furthermore, prolonged corrosion significantly reduces railing strength, potentially leading to structural failure and safety accidents, seriously threatening maritime operations and navigation safety. The installation and disassembly of traditional floating railings are cumbersome, often employing fully welded or densely bolted fixing methods. Installation requires specialized tools and is time-consuming, while disassembly necessitates repeatedly tightening and loosening numerous bolts, resulting in extremely low maintenance and replacement efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a floating hull railing that is easy to assemble quickly, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a floating hull railing that is easy to assemble quickly, comprising a railing body, the railing body including support rods, a crossbar between a pair of support rods, a mounting base at the bottom of the support rods, a self-locking mounting structure between the support rods and the mounting base, a threaded locking structure on the outside of the mounting base, and a buffer positioning structure inside the mounting base.

[0005] As a preferred embodiment of this utility model, the self-locking mounting structure includes a connecting rod located at the bottom of a support rod. A through groove is provided within the mounting base, the through groove matching the size of the connecting rod. A movable groove is located within the mounting base. A connecting rod is provided at the bottom of the connecting rod, and a positive conical component is movably mounted on the connecting rod. An inverted conical component is fixed at the bottom of the connecting rod. Movable grooves are provided around the through groove, and movable locking components are movably mounted within several of these movable grooves. A movable rod is connected to the end of the movable locking component away from the through groove. One end of the movable rod extends to the outside of the mounting base, and a baffle is provided at the other end of the movable rod. A retaining ring is provided between the movable rod and the mounting base, and a return spring is provided between the retaining ring and the movable locking component.

[0006] As a preferred embodiment of this utility model, the threaded locking structure includes a threaded sleeve, which is disposed above the movable rod. A limiting ring is provided above the threaded sleeve, and a rotating sleeve is threadedly connected to the threaded sleeve. A limiting sleeve is provided below the rotating sleeve.

[0007] As a preferred embodiment of this utility model, the buffer positioning structure includes a buffer groove, which is disposed in the mounting base and communicates with the bottom of the through groove. An auxiliary spring is provided in the buffer groove, and a buffer plate is connected to the top of the auxiliary spring.

[0008] As a preferred embodiment of this utility model, the crossbar is provided with a life-saving equipment hook, the bottom of the mounting base is provided with a support connecting plate, and the support connecting plate is provided with several fixing screws.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a technical solution: a floating hull railing that is easy to assemble quickly, such as... Figures 1-3 As shown, the railing includes a railing body 1, which includes support rods 2. A crossbar 3 is provided between a pair of support rods 2. A mounting base 4 is provided at the bottom of the support rods 2. A self-locking mounting structure 5 is provided between the support rods 2 and the mounting base 4. A threaded locking structure 6 is provided on the outside of the mounting base 4. A buffer positioning structure 7 is provided inside the mounting base 4.

[0022] like Figure 3 , Figure 5 , Figure 7 As shown, the self-locking mounting structure 5 includes a connecting rod 501, which is located at the bottom of the support rod 2. A through groove 502 is provided in the mounting base 4, which is sized to match the connecting rod 501. A connecting rod 503 is provided at the bottom of the connecting rod 501. A positive conical part 504 is movably mounted on the connecting rod 503, and an inverted conical part 505 is fixed at the bottom of the connecting rod 503. Movable grooves 506 are provided around the through groove 502, which are located in the mounting base 4. Movable locking parts 507 are movably mounted in several movable grooves 506. A movable rod 508 is connected to one end of the movable locking part 507 away from the through groove 502. One end of the movable rod 508 extends to the outside of the mounting base 4, and a baffle 509 is provided at the other end of the movable rod 508. A retaining ring 510 is provided between the movable rod 508 and the mounting base 4, and a return spring 511 is provided between the retaining ring 510 and the movable locking part 507.

[0023] like Figure 4 , Figure 5As shown, the threaded locking structure 6 includes a threaded sleeve 601, which is located above the movable rod 508. A limiting ring 602 is provided above the threaded sleeve 601. A rotating sleeve 603 is threadedly connected to the threaded sleeve 601, and a limiting sleeve 604 is provided below the rotating sleeve 603.

[0024] like Figure 6 , Figure 7 As shown, the buffer positioning structure 7 includes a buffer groove 701, which is located in the mounting base 4 and communicates with the bottom of the through groove 502. An auxiliary spring 702 is provided in the buffer groove 701, and a buffer plate 703 is connected to the top of the auxiliary spring 702.

[0025] like Figure 4 As shown, the crossbar 3 is equipped with a life-saving equipment hook 301, and the bottom of the mounting base 4 is equipped with a support connecting plate 401, which is provided with several fixing screws 402.

[0026] In practice, the crossbar 3 is reliably installed between a pair of support rods 2 using welding or bolting. A life-saving equipment hook 301 is installed on the crossbar 3, and a support connecting plate 401 is installed at the bottom of the mounting base 4, with screw holes on the support connecting plate 401 matching the fixing screws 402. The mounting base 4 is then securely fixed to the corresponding position on the floating hull by screwing in the fixing screws 402. During railing assembly, the connecting rod 501 at the bottom of the support rod 2 is aligned and inserted into the through slot 502 of the mounting base 4. During this process, the inverted conical piece 505 slides in first, its special shape pressing against the movable locking piece 507, causing it to retract into the movable slot 506. Once the inverted conical piece 505 has completely passed through, the movable locking piece 507 quickly pops out under the elastic force of the return spring 511, precisely locking onto the inverted conical piece 505, completing the initial self-locking installation of the support rod 2 and the mounting base 4. Finally, rotate the rotating screw sleeve 603 to move it downwards, pressing the stop plate 509 against the limiting sleeve 604 to further enhance the locking effect and prevent external force from causing the movable locking part 507 to unlock, ensuring the railing is stable. For reinstallation, repeat the above assembly steps for quick and easy reinstallation of the railing.

[0027] To disassemble the railing, first rotate the rotating screw sleeve 603 upwards to release the pressure on the stop plate 509 and eliminate the constraint of the limiting sleeve 604. Then, press the railing downwards. Under pressure, the conical member 504 again presses against the movable locking member 507, forcing it to retract into the movable groove 506 and causing the movable rod 508 to move outwards. During this process, the movable locking member 507 moves to the upper part of the conical member 504 and presses it to tightly form a single unit with the inverted conical member 505. Finally, with the assistance of the bottom auxiliary spring 702, pull the railing upwards. The movable locking member 507 slides out sequentially from the conical member 504 and the inverted conical member 505, completing the disassembly operation.

[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
