[0032] Refer to Figure 1 、 Figure 3 and Figure 4, An embodiment provided by the present utility model: a multi-functional handrail device for a gangway, including a support plate 1. The tops of two support plates 1 are evenly provided with bottom plates 3 at equal intervals. The tops of multiple bottom plates 3 are fixedly connected with fixing plates 4. At both ends on one side of multiple fixing plates 4, circular grooves 5 are opened. On one side inside multiple circular grooves 5, springs 6 are fixedly connected. One end of multiple springs 6 is fixedly connected with limiters 7. The outer walls of multiple fixing plates 4 are all slidably connected with sliding plates 8. On one side of multiple sliding plates 8, limiting grooves 9 are opened. The tops of multiple sliding plates 8 are fixedly connected with corresponding hollow cross bars 10. At both ends inside two hollow cross bars 10, a first rotating shaft 11 is rotatably connected. On the front sides of two hollow cross bars 10, reserved blocks 12 are provided. The tops of two support plates 1 are fixedly connected with a U-shaped plate 13. On the far away sides of two U-shaped plates 13, a rotating rod 14 is rotatably connected. The adjacent ends of two rotating rods 14 respectively penetrate through the U-shaped plate 13. Two rotating rods 14 are respectively connected with corresponding reserved blocks 12 through pull ropes 15. On the adjacent sides of two support plates 1, pedals 16 are evenly fixedly connected at equal intervals. An installation mechanism 2 is provided on the tops of two support plates 1. The installation mechanism 2 is used for quickly installing and disassembling a handle. Multiple limiters 7 respectively slide with corresponding limiting grooves 9. The sizes of the limiter 7 and the limiting groove 9 are the same;

[0033] Specifically, first install the bottom plate 3 on the support plate 1, then press the limiter 7 to let the spring 6 be pressed into the circular groove 5. Then pull the hollow cross bar 10 to lift the sliding plate 8 upwards. When the limiting groove 9 slides to the position of the limiter 7, the spring 6 will pop out and push the limiter 7 into the limiting groove 9, so that the sliding plate 8 is fixed. Then install the reserved block 12 at the predetermined position, and then rotate the rotating rod 14 to pull the pull rope 15, and use the pull rope 15 to tie the hollow cross bar 10 and the pull rope 15 tightly to make the gangway more stable. When pulling the pull rope 15, the first rotating shaft 11 will also rotate accordingly, so that it is not too strenuous to pull the pull rope 15. Finally, when putting away the handle, press the limiter 7 again to let the limiter 7 and the spring 6 return to the circular groove 5, and then press the hollow cross bar 10, and the sliding plate 8 will move downwards, and the height of the handrail will be lowered, which is convenient for storage.

[0034] Refer to Figure 2 and Figure 5 , the installation mechanism 2 includes a clamping groove 201. Multiple clamping grooves 201 are respectively opened on the tops of corresponding support plates 1. On the far away sides of two support plates 1, limiting plates two 202 are evenly fixedly connected at equal intervals. At the bottoms of multiple limiting plates two 202, limiting bolts 203 are rotatably connected. At the bottoms of multiple bottom plates 3, buckles 204 are fixedly connected. On the top right sides of multiple buckles 204, reserved holes 205 are opened. Multiple buckles 204 respectively slide inside corresponding clamping grooves 201. The sizes of the buckle 204 and the clamping groove 201 are the same;

[0035] Specifically, when installing the handrail, first find the buckle 204, align it with the slot 201, then insert the buckle 204, push it outwards so that the reserved hole can align with the second limiting plate 202. Next, rotate the limiting bolt 203 so that it passes through the second limiting plate 202 and the reserved hole 205. Finally, rotate the nut 23 so that the gasket 24 and the buckle 204 are tightly attached together, thus fixing the buckle 204 to the second limiting plate 202.

[0036] Refer to Figure 1 , soft pads 17 are fixedly connected to the tops of multiple pedals 16, and multiple anti-slip strips 18 are fixedly connected to the tops of the multiple soft pads 17 at equal intervals. The rear sides of two rotating shafts two 19 are rotatably connected to the tops of two support plates 1, and the same first limiting plate 20 is fixedly connected to the rear sides of the two rotating shafts two 19 shown;

[0037] Specifically, the soft pads 17 and the anti-slip strips 18 can increase the friction of the pedals 16 to enhance safety, and the rotating shafts two 19 and the first limiting plate 20 can increase the stability of the gangway ladder.

[0038] Refer to Figure 3 and Figure 5 , the bottoms of the front ends of two support plates 1 are fixedly connected with support frames 21, rubber pads 22 are fixedly connected to the bottoms of the two support frames 21 shown, the tops of multiple limiting bolts 203 are threadedly connected with nuts 23, and gaskets 24 are fixedly connected to the bottoms of the multiple nuts 23;

[0039] Specifically, the support frames 21 and the rubber pads 22 can increase the friction to support the gangway ladder, and the nuts 23 and the gaskets 24 increase the friction surface of the nuts 23 to clamp more tightly and stably.

[0040] Working principle: When using the multifunctional handrail device for the gangway ladder, first install the bottom plate 3 on the corresponding support plate 1. At this time, press the limiter 7 so that the spring 6 is squeezed into the circular groove 5. At the same time, pull the hollow cross bar 10 to move the sliding plate 8 upwards. When the limiting groove 9 moves to the limiter 7, the spring 6 releases pressure to push the limiter 7 out and insert it into the limiting groove 9, and at the same time fix and limit the sliding plate 8. At this time, install the reserved block 12 at the reserved position, and at the same time rotate the rotating rod 14 to pull the pull rope 15. Through the pull rope 15, the hollow cross bar 10 and the pull rope 15 reinforce and stabilize the gangway ladder. At this time, when pulling the pull rope 15, the rotating shaft one 11 rotates accordingly to reduce the friction of the pull rope 15. When putting away the handle, press the limiter 7 so that the limiter 7 and the spring 6 enter the circular groove 5 to press the hollow cross bar 10, so that the sliding plate 8 moves downwards to reduce the height of the handrail for convenient storage;

[0041] And when installing or disassembling the armrest, the buckle 204 needs to be aligned with the card slot 201 first. At this time, insert the buckle 204 into the card slot 201 and move it outwards so that the reserved hole 205 can be aligned with the second limiting plate 202. At the same time, rotate the limiting bolt 203 to penetrate through the second limiting plate 202 and the corresponding reserved hole 205. At this time, rotate the nut 23 to drive the gasket 24 to fit with the buckle 204, so that the buckle 204 is fixed to the second limiting plate 202.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
