The handrail 12 comprises a rod body and an angle code 10 arranged at both ends of the rod body. The rod body is provided with a notch at both ends. A horizontal connecting plate 13 and a vertical connecting plate 14 are arranged in the notch. The horizontal connecting plate 13 and the vertical connecting plate 14 are both welded with the inner wall of the rod body. The vertical connecting plate 14 is provided with a stiffener plate 15. One end of the angle code 10 is bolted with the railing post 9 through a bolt assembly 11. The other end is attached to the stiffener plate 15 and connected with the rod body through a short screw 16. In the embodiment, the connecting device is detachably connected to the angle code 10. After the connecting device is detached, the bolt assembly 11 connecting the railing post 9 on the angle code 10 is detached, so that the handrail can be detached from the railing post 9, thereby being maintained or replaced. Only the connecting device and the angle code 10 are involved in the detachment process, and no local deformation of the railing is caused.

[0031] The cross section of the connecting device is consistent with the cross section of the handrail. The connecting device comprises a circular main component 1, an arc-shaped rotating fastener 2, and a rotating pressing block 3. The overall structure of the circular main component 1 is tubular. An opening is arranged above the circular main component 1, and a vertical plate 14 is further arranged inside, thereby dividing the circular main component 1 into a disassembly area and a working active area. Specifically, the disassembly area is used for close connection with the angle code 10, and the working active area is used for the activity of the pin shaft 4, the arc-shaped rotating fastener 2, and the rotating pressing block 5. In the embodiment, the left upper part of the vertical plate 17 is further provided with a horizontal plate 18 in the horizontal direction, which is used for corresponding abutment with the angle code 10.

[0032] As shown in Figure 3 , 4 The both ends of the circular main component 1 are provided with sealing plates, which are provided with round holes. The pin shaft 4 is arranged in the round hole. The circular main component 1 is rotationally connected with the arc-shaped rotating fastener 2 through the pin shaft 4. In the embodiment, the circular arc surface of the arc-shaped rotating fastener 2 corresponds to the opening arranged on the circular main component 1. The opening of the circular main component 1 is opened or closed by rotating the arc-shaped rotating fastener 2, that is, the opening or closing of the disassembly area. Specifically, the disassembly area can be opened by rotating the arc-shaped rotating fastener 2 clockwise, and the disassembly area can be closed by rotating the arc-shaped rotating fastener counterclockwise.

[0033] One side of the vertical plate 17 is fixedly provided with a pressing block base 5. The pressing block base 5 is arranged at the middle segment of the circular main component 1. The surface of the pressing block base 5 is provided with an arc-shaped groove 19 and corresponds to the rotating pressing block 3. Specifically, the pressing block base 5 is arranged in the working active area and is specifically provided with two, which are arranged on both sides of the baffle 7 and are fixedly arranged on the inner wall of the circular main component 1.

[0034] The middle section of the circular main component 1, the working active area is fixedly provided with a baffle 7, and the baffle 7 is located on the inner wall of the circular main component 1, so that when the rotating pressing block 7 rotates along the arc direction of the circular main component 1, the rotating pressing block 3 is blocked on the circular main component 1 after rotating clockwise. Specifically, an opening is also provided in the working active area of the circular main component 1, and the opening is provided with the baffle 7, and the length of the baffle 7 is lower than the height provided by the arc-shaped groove 19 on the pressing block base 5, and a certain gap is left between the baffle 7 and the circular main component 1 to provide a moving space for the rotating pressing block 3, and a rotating space is also left between the rotating pressing block 3 and the circular main component 1 when the rotating pressing block 3 is attached to the baffle. The rotating pressing block 3 is rotated clockwise with the arc-shaped groove 19 as the center, so that the upper arc-shaped protrusion 21 of the rotating pressing block 3 lifts the arc-shaped rotating buckle 2, and rotates downward to the bottom edge of the circular main component, and then the arc-shaped rotating buckle 2 can be rotated downward, so that one side of the circular main component 1 is in an open state, and then the connecting device can be removed or installed. In the embodiment, the rotating pressing block 3 is in a semicircular shape, consistent with the arc surface of the circular main component, and the lower end of the arc plate corresponds to the rotating space left by the arc surface of the baffle 7 and the circular main component 1.

[0035] As shown in Figure 5 , 6 , the arc-shaped rotating buckle 2 is provided at the opening of the circular main component 1, and two ends of the arc-shaped rotating buckle 2 are provided with circular holes with the same diameter as the circular main component 1 for the pin shaft 4 to pass through. The lower end of the arc-shaped rotating buckle is provided with an arc-shaped clamping groove 20 corresponding to the upper arc-shaped protrusion 21 of the rotating pressing block 3. A clamping buckle 23 is also provided on the same side of the arc-shaped rotating buckle 2, which extends and bends inwardly to the end of the circular main component 1, and is movably buckled to limit the rotation of the arc-shaped rotating buckle 2, thereby limiting the opening and closing of the disassembly area.

[0036] As shown in Figure 7 , 8 , the rotating pressing block 3 is provided on the pressing block base 5, and the rotating pressing block 3 includes an upper arc-shaped protrusion 21 and a lower arc-shaped protrusion 22, which are arranged in parallel on the left and right sides. The surface of the upper arc-shaped protrusion 21 is attached to the arc-shaped rotating buckle 2, and the surface of the lower arc-shaped protrusion 22 corresponds to the arc-shaped groove 19 of the pressing block base 5.

[0037] The inner wall of the circular main component 1 is fixedly provided with a rib plate 6, which is arranged on both sides of the vertical plate 17 and fixedly connected with the pressing block base 5. The rib plate 6, the vertical plate 17 and the pressing block base 5 are fixedly connected to the inner wall of the circular main component 1, so as to strengthen the rigidity of the pressing block base 5, reduce the pressure generated by the rotating pressing block 3 pressing on the pressing block base 5, and reduce the large deformation caused by rotation.

[0038] It also includes a connecting bolt 8, which passes through the circular main component 1 and the rotating pressure block 3, and simultaneously connects and fixes the rotating pressure block 3, the baffle 7 and the vertical plate 17 to prevent the circular main component 1 and the rotating pressure block 3 from rotating relative to each other. At the same time, the connecting bolt 8 also passes through the corner bracket 10 and is fixedly connected to the corner bracket 10.

[0039] The installation and disassembly process of this utility model is as follows:

[0040] like Figure 9 As shown, firstly, the railing posts 9 and the corner brackets 10 at both ends of the handrail 12 are connected through the bolt assembly 11. Simultaneously, the handrail 12 is temporarily fitted onto the corner brackets 10. Horizontal connecting plates 13 and vertical connecting plates 14 are welded to both ends of the handrail 12. The upper and lower ends of the vertical connecting plate 14 are fixedly connected to the inner wall of the handrail 12. The position of the handrail 12 is adjusted so that the vertical connecting plate 14 is tightly against the vertical edge of the corner bracket 10, and the horizontal connecting plate 13 is placed above the horizontal edge of the corner bracket 10, with provisions for the left and right positions of the connecting device. After adjusting the position of the handrail 12, the corner bracket 10 is connected to the vertical connecting plate 14 inside the handrail 12 using short screws 16.

[0041] When installing the connecting device, rotate the rotating pressure block 3 clockwise along the arc of the circular main component 1, causing the arc-shaped rotating fastener 2 to rotate downwards clockwise as well. This creates an opening between the circular main component 1 and the arc-shaped rotating fastener 2, opening the working area on the left side of the circular main component 1. The connecting device is then fitted onto the corner bracket 10. The vertical plate 17 inside the circular main component 1 is pressed tightly against the vertical edge of the corner bracket 10, while the top of the corner bracket 10 abuts against the horizontal plate 18 at the top of the vertical plate 17. Then, rotate the rotating pressure block 3 counterclockwise, causing the arc-shaped rotating fastener 2 to rotate counterclockwise along the upper arc-shaped protrusion 21 on the rotating pressure block 3, thus creating a closed state between the circular main component 1 and the arc-shaped rotating fastener 2. The circular main component 1, the rotating pressure block 3, and the corner bracket 10 are connected together using connecting bolts 8 to prevent the circular main component 1 and the rotating pressure block 3 from moving relative to each other, and also to fix the connecting device on the corner bracket 10, thus completing the installation of the connecting device and the handrail 12 on the railing post 9.

[0042] When disassembling the connecting device and handrail, first unscrew the connecting bolt 8, then pry the rotating pressure block 3 clockwise along the arc of the circular main component 1, so that the circular main component 1 and the arc-shaped rotating fastener 2 are in an open state. At this time, remove the connecting device from the corner bracket 10. Afterwards, unscrew the bolt assembly 11, and the handrail 12 and corner bracket 10 can be removed from the railing post 9, completing the disassembly of the connecting device and handrail from the railing post.

[0043] The railings are divided into three parts by using the combined railing handrail form, the middle part is a conventional round railing handrail, and the two ends are detachable railing handrail connecting devices. The detachable railing handrail connecting device is composed of a round main component, an arc-shaped rotating fastener and a rotating pressing block. By pressing or bending the rotating pressing block, the round main component can be in a closed or open state, so that the railing handrail can be conveniently assembled and disassembled, and local deformation of the railing handrail will not be caused during the assembling and disassembling process.

[0044] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles described in the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
