Description

Technical Field

[0001] This utility model relates to the field of ship guardrail technology, specifically a ship guardrail with sliding and telescopic function. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation that can navigate or anchor in waterways for transport or operations. Depending on the specific requirements of its use, a ship has different technical specifications, equipment, and structural forms. Ships are man-made transportation tools that primarily operate in geographical waters. Ships are generally equipped with guardrails to prevent the risk of people falling overboard.

[0003] The installation of guardrails can prevent the risk of people falling into the water. Traditional ship guardrails generally do not have sliding and telescopic functions, so it is inconvenient for people to get on and off cargo and personnel when the ship is docked. Sometimes, when it is necessary to cross the guardrail, it is necessary to climb over the guardrail, which is very inconvenient. At the same time, without guardrails, people are at risk of falling into the water. Utility Model Content

[0004] The purpose of this invention is to provide a ship guardrail with sliding and telescopic functions to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A ship guardrail with sliding and telescopic function includes a base. A pair of connecting sleeves are mounted on the top surface of the base. A sliding rod slides inside the connecting sleeves. Several upward-sloping slots are formed on the side of the sliding rod. A fixing component is installed inside the connecting sleeve, engaging with the slots. A fixing block is mounted on the top of the sliding rod. Guardrails are rotatably connected to the sides of both the connecting sleeves and the fixing blocks. Connectors are provided between pairs of guardrails at the same height, linking them together. The height of the guardrails can be flexibly adjusted by the sliding of the sliding rod within the connecting sleeves and the engagement of the fixing component with the slots, facilitating cargo loading and unloading and personnel boarding and alighting when the ship is docked. The rotatable connection of the guardrails and the connecting components allows the guardrails to be retracted when protection is not needed, increasing operational convenience; when protection is required, they can be quickly deployed and connected to form an effective protective barrier, ensuring personnel safety and reducing the risk of falling overboard. The overall structural design balances the dual needs of protection and ease of use, improving the practicality and safety of the ship guardrail.

[0007] Furthermore, the fixing component includes a fixing frame installed inside the connecting sleeve. A rotating shaft is rotatably connected inside the fixing frame. A connecting plate is installed on the outer side of the rotating shaft, and a torsion spring is also fitted on the outer side of the rotating shaft. Both ends of the torsion spring are connected to the fixing frame and the connecting plate, respectively. A pin is installed on the outer side of the connecting plate near its top, and the pin engages with a slot. Utilizing the elasticity of the torsion spring, the pin maintains its engagement with the slot, ensuring the sliding bar remains stably fixed after height adjustment. This prevents accidental sliding of the sliding bar due to factors such as ship swaying, ensuring the stability of the guardrail height and safety of use. Simultaneously, the torsion spring design makes adjusting the sliding bar height easy and convenient, requiring only overcoming a small amount of torsion spring resistance.

[0008] Furthermore, the inner wall of the fixing frame is provided with an arc-shaped groove. One end of the pin connected to the connecting plate passes through the connecting plate and slides in the arc-shaped groove. The arc-shaped groove provides a sliding track for the pin, further constraining the movement trajectory of the pin, making it more stable when rotating with the connecting plate, and enhancing the overall stability and reliability of the fixing component.

[0009] Furthermore, the arc center of the arc groove is located on the axis of the rotating shaft. The design that the arc center coincides with the axis of the rotating shaft makes the movement of the pin smoother and more stable when it slides in the arc groove, avoiding jamming.

[0010] Furthermore, the outer side of the connecting sleeve has an opening, and the fixing frame is installed in the opening by screws. The opening on the outer side of the connecting sleeve and the screw installation method facilitate the installation and disassembly of the fixing frame.

[0011] Furthermore, a threaded hole is provided at one end of the shaft that connects to the fixed frame, and a through hole is provided on the back of the fixed frame. The threaded hole and the through hole are connected, and a bolt slides in the through hole. The bolt and the threaded hole are threadedly engaged. This fixing method can fix the shaft to rotate, so that the pin cannot swing, and further fix the slide rod at the adjusted height.

[0012] Furthermore, the connector includes a slot formed at the free end of one of the guardrails and a fixing plate installed at the free end of the other guardrail. The fixing plate slides within the slot, and a fixing bolt connects the fixing plate and the guardrail. A pair of connecting blocks are installed on the sides of the connecting sleeve and the fixing block. The guardrail is installed between the pair of connecting blocks via a connecting shaft. This connection method allows the user to easily separate the pair of guardrails, thereby exposing the space between the pair of sliding rods and the pair of connecting sleeves, which facilitates personnel movement and the handling of goods.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This ship guardrail with sliding and telescopic function allows for flexible adjustment of the guardrail height through the sliding of the sliding rod within the connecting sleeve and the engagement of the fixing component with the slot. When the ship is docked for cargo loading / unloading and personnel boarding / alighting, the guardrail can be adjusted to a suitable height, avoiding the inconvenience caused by the fixed height of traditional guardrails, reducing the need for personnel to climb over the guardrail, and greatly improving operational convenience. Furthermore, the rotating connection of the guardrail and the adjustable connecting component allow the guardrail to be retracted when protection is not required, further facilitating personnel movement and cargo handling, and optimizing the space utilization of the ship's deck.

[0019] 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.

[0020] Please see Figures 1-4This utility model provides a technical solution: a ship guardrail with sliding and telescopic function, including a base 1, a pair of connecting sleeves 2 installed on the top surface of the base 1, a sliding rod 3 sliding inside the connecting sleeves 2, several upwardly inclined slots 4 opened on the side of the sliding rod 3, a fixing component installed inside the connecting sleeves 2, the fixing component engaging with the slots 4, a fixing block 5 installed at the top of the sliding rod 3, and guardrails 7 rotatably connected to the sides of both the pair of connecting sleeves 2 and the fixing block 5, with connecting components between the pair of guardrails 7 at the same height, connecting the pair of guardrails 7 at the same height together. When it is necessary to adjust the height of the guardrail 7, an external force is applied to pull the sliding rod 3 upward, and the sliding rod 3 slides within the connecting sleeves 2. Because the slots 4 are inclined upward, the pin 14 of the fixing component will move within the slot 4. When the appropriate height is reached, the fixing component, under its own structural action, causes the pin 14 to engage with the slot 4, thereby fixing the position of the sliding rod 3 and realizing the adjustment of the height of the guardrail 7. The guardrail 7 can rotate around the rotating connection point with the connecting sleeve 2 and the fixing block 5. When the guardrail needs to be retracted, it is rotated to make it parallel to the ship's deck; when protection is needed, the guardrail is rotated to unfold, and a pair of guardrails at the same height are connected by the connector to form a protective railing.

[0021] As an embodiment of this utility model, the fixing component further includes a fixing frame 11 installed inside the connecting sleeve 2. A rotating shaft 12 is rotatably connected inside the fixing frame 11. A connecting plate 13 is installed on the outside of the rotating shaft 12. A torsion spring 15 is also fitted on the outside of the rotating shaft 12. The two ends of the torsion spring 15 are respectively connected to the fixing frame 11 and the connecting plate 13. A pin 14 is installed on the outside of the connecting plate 13 near its top, and the pin 14 engages with the slot 4. When the sliding rod 3 is pushed upward, the pin 14 is squeezed by the slot 4, causing the connecting plate 13 to rotate around the rotating shaft 12. The torsion spring 15 deforms. When the sliding rod 3 stops rising, the elastic force of the torsion spring 15 pushes the connecting plate 13, causing the pin 14 to engage with the slot 4, thus fixing the sliding rod 3. Since the slot 4 is inclined upward, when the sliding rod 3 is pressed down, the pin 14 is squeezed obliquely downward, so that it will not rotate, thus preventing the sliding rod 3 from being pressured and moving downward.

[0022] In one embodiment of this utility model, the inner wall of the fixing frame 11 is further provided with an arc-shaped groove 16. One end of the pin 14 connected to the connecting plate 13 passes through the connecting plate 13 and slides within the arc-shaped groove 16. During the rotation of the connecting plate 13 around the pivot 12, one end of the pin 14 connected to the connecting plate 13 slides within the arc-shaped groove 16. The shape and position of the arc-shaped groove 16 determine the movement path of the pin 14, ensuring that the pin 14 rotates stably within the fixing frame 11, thereby ensuring the stable engagement operation of the pin 14 with the slot 4.

[0023] As an embodiment of this utility model, the arc center of the arc groove 16 is located on the axis of the rotating shaft 12. Since the arc center of the arc groove 16 coincides with the axis of the rotating shaft 12, when the connecting plate 13 rotates around the rotating shaft 12, the radius of the pin 14 sliding in the arc groove 16 remains unchanged, and the movement trajectory is more regular, thereby ensuring the stability of the pin 14 in the process of engaging and disengaging with the slot 4, and reducing the situation of jamming or insecure fixing caused by uneven movement.

[0024] As an embodiment of this utility model, the outer side of the connecting sleeve 2 is further provided with an opening, and the fixing frame 11 is installed in the opening by screws. When installing the fixing frame 11, the fixing frame 11 is aligned with the opening on the outer side of the connecting sleeve 2, and the fixing frame 11 is fixed on the connecting sleeve 2 by screws. When the fixing frame 11 is removed, the pin 14 is disengaged from the slot 4, and the slide rod 3 moves down to reset under the action of gravity.

[0025] As an embodiment of this utility model, a threaded hole is further provided at one end of the shaft 12 and the fixed frame 11, and a through hole is provided on the back of the fixed frame 11. The threaded hole and the through hole are connected, and a bolt slides in the through hole, and the bolt and the threaded hole are threadedly engaged.

[0026] As an embodiment of this utility model, the connector further includes a slot 8 formed at the free end of one of the guardrails 7 and a fixing plate 9 installed at the free end of the other guardrail 7. The fixing plate 9 slides in the slot 8, and a fixing bolt 10 connects the fixing plate 9 and the guardrail 7. A pair of connecting blocks 6 are installed on the sides of the connecting sleeve 2 and the fixing block 5. The guardrail 7 is installed between the pair of connecting blocks 6 through a connecting shaft. When it is necessary to connect a pair of guardrails 7, the fixing plate 9 at the free end of one guardrail 7 is inserted into the slot 8 at the free end of the other guardrail 7, and the fixing plate 9 and the guardrail 7 are fixed together by the fixing bolt 10, so that the pair of guardrails 7 are connected into a stable protective structure.
