[0048] like Figure 1-Figure 8 As shown, the present invention provides an adjustable handrail for shipbuilding. The adjustable handrail comprises a handrail structure 1 and a frame structure 2. Among them, the handrail structure 1 includes a distance adjusting device 11 and two fixed sleeves 12, the two fixed sleeves 12 extend in the horizontal direction and are arranged opposite to each other, the two fixed sleeves 12 are fixedly connected to the two binding bridge columns 100 one by one, the distance adjusting device 11 includes an adjusting rod 111 and an adjusting sleeve rod 112, one end of the adjusting rod 111 is fixedly connected to one fixed sleeve 12, and the other end can be slidably extended into the adjusting sleeve rod 112, the end of the adjusting sleeve rod 112 away from the adjusting rod 111 is fixedly connected to the other fixed sleeve 12, and the two ends of the adjusting sleeve rod 112 can be locked to the fixed sleeve 12 and the adjusting rod 111 one by one; the frame structure 2 includes a connecting sleeve rod 21 and two frame bodies 22, the two frame bodies 22 are fixedly connected to the two fixed sleeves 12 one by one, one end of the connecting sleeve rod 21 is fixedly connected to one frame body 22, and the other end is slidably connected to the other frame body 22.

[0049] The handrail structure 1 and the frame structure 2 cooperate with each other to form an integral railing structure. During the installation process, one end of the adjusting rod 111 can be first fixedly connected to a fixed sleeve 12, and then the adjusting sleeve 112 can be locked to the adjusting rod 111 according to the actual spacing between the two lashing bridge columns 100 of the ship, and the other end can be fixedly connected to the fixed sleeve 12. The order of steps can also be adjusted according to the needs during the installation process. The installation steps are simple and modular production is convenient.

[0050] It should be noted that the height of each structure in the adjustable railing meets the requirements for the installation of railing protection in the 1966 International Convention on Load Lines as amended by Resolution MSC143(77).

[0051] Illustratively, in this embodiment, one end of the adjusting sleeve rod 112 away from the adjusting rod 111 is welded to the fixing sleeve 12 .

[0052] Specifically, the adjusting rod 111 is fixedly connected to one end of the fixing sleeve 12 and is provided with a threaded section 1111 and a fine-tuning assembly 113, and the fine-tuning assembly 113 includes a fixing portion 1131 and a rotating portion 1132. The fixing portion 1131 is fixedly connected to the fixing sleeve 12; the rotating portion 1132 is rotatably connected to the fixing portion 1131, and the threaded section 1111 is screwed to the rotating portion 1132. When the rotating portion 1132 rotates relative to the fixing portion 1131, the threaded section 1111 can approach and move away from the fixing portion 1131. The above arrangement ensures that the adjusting rod 111 cannot rotate around its own axis, and at the same time, by twisting the rotating portion 1132, the threaded section 1111 can move relative to the rotating portion 1132 in the horizontal direction, thereby changing the overall length of the adjusting rod 111, which has a simple structure, low production cost, and is not easy to damage.

[0053] More specifically, the adjusting rod 111 is a round rod structure, and a limiting tenon 1112 extending along its own axial direction is convexly provided on the adjusting rod 111, and the limiting tenon 1112 is rectangular, and a limiting groove is provided on the adjusting sleeve rod 112, and when the adjusting rod 111 is inserted into the adjusting sleeve rod 112, the limiting tenon 1112 can be inserted into the limiting groove. With the above arrangement, when the rotating part 1132 is twisted, the limiting tenon 1112 is pressed against the inner wall of the limiting groove to prevent the adjusting rod 111 from rotating around its own axial direction.

[0054] For example, in this embodiment, the outer peripheral side of the rotating part 1132 is provided with an anti-skid structure, which can be an anti-skid pad, such as a rubber pad, etc.; or, the anti-skid structure is an anti-skid protrusion, which can be a dot-shaped protrusion, or a pattern protrusion of any shape, as long as it can increase the contact friction between the position where it is located and the worker's hand or other working tools. The specific form is referred to the prior art and is not specifically limited in this embodiment.

[0055] For example, in this embodiment, the fixed portion 1131 and the rotating portion 1132 may be rotationally connected via a bearing commonly used in the art.

[0056] Specifically, the adjustable handrail further includes a locking member 3, a plurality of through first locking holes 1110 are spaced apart along the extension direction of the adjusting rod 111, and a through adjusting hole 1120 is spaced apart along the extension direction of the adjusting sleeve rod 112, and when any first locking hole 1110 is connected to any adjusting hole 1120, the locking member 3 can sequentially extend into the adjusting hole 1120 and the first locking hole 1110. The above-mentioned arrangement of the locking member 3 can select the first locking hole 1110 and the adjusting hole 1120 at appropriate positions according to actual installation requirements, so as to change the length of the adjusting rod 111 extending into the adjusting sleeve rod 112, and then the adjusting rod 111 and the adjusting sleeve rod 112 are locked by the locking member 3, which has a simple structure, strong versatility, can be applied to a variety of different working conditions, and is not easy to be damaged.

[0057] More specifically, a plurality of first locking holes 1110 are all formed on the limiting tenon 1112 , and the through direction of the first locking holes 1110 is perpendicular to the extending direction of the adjusting rod 111 , so as to increase the force-bearing area of ​​the locking member 3 .

[0058] Illustratively, in this embodiment, the locking member 3 is specifically a rivet, pin or tenon structure commonly used in the art, which is not specifically limited herein.

[0059] For example, in this embodiment, the length of the threaded section 1111 is equal to twice the distance between two adjacent first locking holes 1110. With the above arrangement, during installation, the adjustment rod 111, the adjustment sleeve rod 112 and the fixed sleeve 12 can be used to make a rough adjustment, and then the threaded section 1111 and the fine adjustment assembly 113 can be used to make a finer adjustment, which has high precision, strong versatility, simple operation, and a durable structure that is not easily damaged.

[0060] Specifically, the adjustable railing also includes a first hook structure 4, which includes a first sliding portion 41 and a first hook portion 42. The first sliding portion 41 is slidably arranged inside the fixed sleeve 12, and the first sliding portion 41 is provided with a third locking hole.

When the third locking hole is connected to any of the second locking holes, the locking member 3 can be inserted into the second locking hole and the third locking hole in sequence; the side wall of the fixed sleeve 12 of the first hook portion 42 is provided with a through sliding hole, and the sliding hole extends along the extension direction of the fixed sleeve 12. The first hook portion 42 is fixedly connected to the first sliding portion 41 and extends out of the sliding hole. With the above arrangement, the first sliding portion 41 can drive the first hook portion 42 to slide along the fixed sleeve 12, so as to prevent the first hook portion 42 from interfering with the tying flower basket 200 during the installation process. The arrangement has high flexibility and strong versatility, and is convenient for adjustment according to the size of the container.

[0061] Specifically, the frame body 22 includes a vertical bar portion 221 and a horizontal bar portion 222. Among them, a plurality of horizontal bar portions 222 are arranged at intervals along the vertical direction, one end of the horizontal bar portion 222 is fixedly connected to the vertical bar portion 221, the horizontal bar portion 222 of one frame body 22 corresponds to the horizontal bar portion 222 of another frame body 22, and two horizontal bar portions 222 at the same height are provided with a connecting sleeve rod 21. With the above arrangement, the vertical bar portion 221 and the horizontal bar portion 222 cooperate with each other, and the horizontal bar portion 222 can be arranged according to installation requirements, with strong versatility.

[0062] Specifically, the frame structure 2 further includes a second hook structure 23, and the second hook structure 23 includes a second sliding portion 231 and a second hook portion 232. The second sliding portion 231 is slidably mounted on the frame body 22, and the second sliding portion 231 can be locked to the frame body 22; the second hook portion 232 is fixedly connected to the second sliding portion 231. With the above arrangement, the second hook structure 23 can drive the second hook portion 232 to slide along the frame body 22, thereby preventing the second hook portion 232 from interfering with the tying flower basket 200 during installation, with high flexibility and strong versatility, and is easy to adjust according to the size of the container.

[0063] More specifically, the second sliding portion 231 includes two splicing pieces that can be symmetrically spliced ​​on the frame body 22, and the two splicing pieces can be locked to each other by bolts. The above arrangement has a simple structure and is not easy to damage. The two splicing pieces can be locked to each other or separated by a screwdriver, which is easy to operate. For example, in this embodiment, the second sliding portion 231 is sleeved on the outer peripheral side of the crossbar portion 222.

[0064] Specifically, the adjustable railing further comprises a railing post 5, which extends in the vertical direction, and one end of which is fixedly connected to the fixing sleeve 12, and the other end of which is fixedly connected to the frame body 22, and the railing post 5, the fixing sleeve 12 and the frame body 22 correspond to each other.
