[0022] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0023] like Figures 1-7 The detachable and adjustable marine railing shown includes spaced-apart uprights 1 and crossbars 2 located between adjacent uprights 1. An angle adjustment seat 3 is connected to the lower end of each upright 1. The uprights 1 can swing back and forth relative to the angle adjustment seat 3 and can be locked by the angle adjustment seat 3. Vertical grooves 4 are provided on both the left and right side walls of the uprights 1. Slider blocks 5 that can slide in the vertical grooves 4 are provided at both ends of each crossbar 2. Fixing components that can fix the sliders 5 in the vertical grooves 4 are also provided at both ends of the crossbar 2.
[0024] Based on the above structure, an angle adjustment seat 3 is firstly installed at the lower end of the upright 1, so that the angle of the upright 1 can be adjusted according to the installation requirements; in addition, a vertical slide groove 4 is installed on the upright 1, and the slider 5 at the end of the crossbar 2 can slide in the vertical slide groove 4, so that the height position of the crossbar 2 can be adjusted, and the number of crossbars 2 can be increased or decreased according to the actual situation, which greatly improves the practicality of the railing and provides effective safety protection for the crew.
[0025] See Figure 3 , Figure 7 As shown, the fixing assembly includes a fixing rod 21 that passes through the ends of the horizontal bar 2 on the left and right. Several fixing holes 22 are evenly distributed vertically on the inner side wall of the vertical groove 4. A transverse groove 23 is provided on the lower side of the horizontal bar 2. One end of the fixing rod 21 can be movably inserted into the fixing hole 22, and the other end extends into the transverse groove 23 and is provided with a movable seat 24. The movable seat 24 can slide left and right along the transverse groove 23, so that one end of the fixing rod 21 can be inserted into or pulled out of the fixing hole 22.
[0026] When the fixed component is in operation, the movable seat 24 can be moved by hand, thereby causing one end of the fixed rod 21 to be inserted into or pulled out of the fixed hole 22, so as to fix or separate the crossbar 2.
[0027] Furthermore, a spring 31 is connected between the movable seat 24 and the side wall of the transverse slot 23 to keep the fixing rod 21 facing outward, thereby improving the stability of the fixing rod 21 when it is inserted into the fixing hole 22.
[0028] Furthermore, a limiting plate 41 is hinged to one side of the movable seat 24 relative to the fixed rod 21. The limiting plate 41 can be flipped up and down. An outwardly protruding flange 42 is provided on the movable seat 24 and on the lower side of the limiting plate 41. The limiting plate 41 can be flipped down and abutted against the flange 42 to keep the limiting plate 41 in a horizontal state. When the limiting plate 41 is in a horizontal state, one end of the limiting plate 41 abuts against the side wall of the transverse slot 23, thereby restricting the movement of the movable seat 24.
[0029] When the fixing rod 21 is inserted into the fixing hole 22, the limiting plate 41 can swing downward under its own weight and abut against the flange 42, and the limiting plate 41 is in a horizontal position (e.g., Figure 3 As shown in the figure, at this time, one end of the limiting plate 41 abuts against the side wall of the transverse slot 23, so the movable seat 24 cannot move, and the fixing rod 21 can be stably inserted into the fixing hole 22. If adjustment is required, the limiting plate 41 can be pushed up with a finger, and then the movable seat 24 can be moved.
[0030] In order to improve the smooth sliding of the slider 5 in the vertical groove 4, ball bearings 51 are provided on both the front and rear sides of the slider 5. The ball bearings 51 can roll against the side wall of the vertical groove 4.
[0031] See Figure 4 , Figure 6 As shown, the angle adjustment seat 3 includes a mounting base plate 61, with hinge seats 62 spaced apart on the mounting base plate 61. An extension seat 63 is provided at the lower end of the upright 1, and a rotating shaft 64 is provided on the extension seat 63. The extension seat 63 is located between the two hinge seats 62, and the rotating shaft 64 is rotatably connected to the two hinge seats 62. Through holes 65 are also provided on the extension seat 63. Several adjustment holes 66 are evenly distributed around the rotating shaft 64 along the circumference of the hinge seat 62. The seat also includes a fixing rod 67, which can be inserted into the adjustment holes 66 and the through holes 65 in sequence.
[0032] When adjusting the angle, first pull out the fixing rod 67. At this time, the upright 1 can swing to adjust the angle by rotating the shaft 64. After the adjustment is completed, insert the fixing rod 67 into the corresponding adjustment hole 66 and through hole 65 to fix the upright 1.
[0033] Furthermore, both ends of the fixing rod 67 extend outwards, and external threads are provided on the outer walls of both ends of the fixing rod 67, with nuts 71 threaded onto the external threads; thereby improving the stability of the upright 1 after it is fixed.
