[0002] Railings are usually installed on stairs, balustrades, balconies, etc. They have both practical and decorative functions. They are components on the upper edge (top surface) of railings or balustrades for people to hold on to. They are used for walking and are required to be safe, firm, beautiful, smooth and without sharp edges. Railings are divided into wooden handrails, plastic handrails, metal handrails, etc. according to the material. There are many forms of handrails. Outdoor railings are exposed to the sun and rain, and bear impact loads. They often have local deformation and damage and need to be replaced.

[0003] At present, conventional metal handrails are welded or buckled. When considering later maintenance, if welding is used, the handrails are welded to the railing posts. To replace the handrails, the original handrails need to be cut off and re-welded, which is difficult to construct. If the open type is used, the main components of the handrails are connected to the railing posts, and then the gussets are buckled to the opening. When disassembling, the gussets need to be removed first, and then the handrails can be removed. When the gussets are removed, they are often deformed and cannot be used.

[0004] In view of the above practical needs and current technical shortcomings, a connection device is needed that can achieve smooth disassembly and maintenance and will not cause local deformation of the railing during the disassembly and assembly process. Summary of the invention

The device is connected to the angle code fixed at both ends of the handrail column, and the arc-shaped rotating fastener is rotated and the rotating pressure block is pressed on the circular handrail main component. Finally, the handrail connection device is fixed to the angle code at both ends of the handrail column by using a long screw, so that installation and disassembly are relatively convenient.

[0006] In order to solve the above technical problems, an embodiment of the present invention provides a detachable handrail connection device, comprising a circular main component, an arc-shaped rotating fastener and a rotating pressing block, wherein the circular main component is tubular, has an opening on the top, and is further provided with a vertical plate inside, a pressing block base is fixedly provided on one side of the bottom of the vertical plate, the pressing block base is provided in the middle section in the length direction of the circular main component, and an arc-shaped groove is provided on the surface of the pressing block base; The rotating pressing block is arranged on the pressing block base, and the rotating pressing block comprises an upper arc-shaped protrusion and a lower arc-shaped protrusion, the surface of the upper arc-shaped protrusion corresponds to the arc-shaped rotating buckle, and the surface of the lower arc-shaped protrusion corresponds to the pressing block base; The arc-shaped rotating fastener is arranged at the opening of the circular main component, and one end of the arc-shaped rotating fastener is provided with an arc-shaped groove corresponding to the upper arc-shaped protrusion of the rotating pressing block.

[0007] Wherein, sealing plates are arranged at both ends of the circular main component, a circular hole is opened on the sealing plate, a pin is arranged through the circular hole, and the circular main component is rotatably connected with the arc-shaped rotating fastener through the pin passing through the circular hole.

[0008] Wherein, the circular main component and the outer surface of the arc-shaped rotating fastener are on the same arc surface.

[0009] Wherein, a stopper is fixedly arranged on the circular main component, and the stopper is blocked between the rotating pressing block and the circular main component.

[0012] It also includes connecting bolts, through which the rotating pressure block, the stopper and the vertical plate are connected.

[0013] The present invention also provides a method for installing a detachable handrail connecting device, comprising the following steps: S1. Use bolt assemblies to connect the railing posts with the angle brackets at both ends of the handrails, temporarily put the handrails on the angle brackets, and fix the upper and lower ends of the vertical connecting plate to the inner wall of the handrails; S2. Adjust the position of the handrail, place the vertical connection plate close to the vertical edge of the angle bracket, place the horizontal connection plate on the horizontal edge above the angle bracket, and reserve the left and right positions of the connection device; after adjusting the position of the handrail, use short screws to connect the angle bracket with the vertical connection plate inside the handrail; S3.

In this embodiment, the connecting device is detachably connected to the angle bracket 10. After disassembling the connecting device, the bolt assembly 11 connecting the railing column 9 on the angle bracket 10 is disassembled to remove the handrail from the railing column 9 for repair or replacement. The disassembly process only involves the disassembly of the connecting device and the angle bracket 10, and will not cause local deformation of the railing.

[0020] The cross section of the connecting device is consistent with the cross section of the handrail. The connecting device includes a circular main component 1, an arc-shaped rotating fastener 2 and a rotating pressure block 3. The overall structure of the circular main component 1 is tubular. An opening is provided on the top of the circular main component 1, and a vertical plate 14 is also provided inside, which divides the circular main component 1 into a disassembly area and a working activity area. Specifically, the disassembly area is used for close connection with the angle code 10, and the working activity area is used for the movement of the pin 4, the arc-shaped rotating fastener 2 and the rotating pressure block 5. In this embodiment, a horizontal plate 18 in the horizontal direction is also provided on the upper left side of the vertical plate 17, which is used to abut against the angle code 10.

[0021] like Figure 3 , 4As shown, the two ends of the circular main component 1 are provided with sealing plates, and the sealing plates are provided with circular holes, and the circular holes are provided with pins 4, and the circular main component 1 is rotatably connected with the arc-shaped rotating fastener 2 through the pins 4. In this embodiment, the arc surface of the arc-shaped rotating fastener 2 corresponds to the opening provided on the circular main component 1, and the opening or closing state of the circular main component 1 is achieved by rotating the arc-shaped rotating fastener 2, that is, the opening or closing state of the disassembly area. Specifically, the disassembly area can be opened by rotating the arc-shaped rotating fastener 2 clockwise, and can be closed by rotating the arc-shaped rotating fastener counterclockwise.

[0022] A pressure block base 5 is fixedly arranged on one side of the vertical plate 17, and the pressure block base 5 is arranged in the middle section of the circular main component 1. An arc groove 19 is arranged on the surface of the pressure block base 5 and corresponds to the rotating pressure block 3. Specifically, the pressure block base 5 is arranged in the working activity area, and there are two pressure block bases 5, which are respectively arranged on both sides of the baffle 7 and fixedly arranged on the inner wall of the circular main component 1.

[0023] A baffle 7 is fixedly arranged in the middle section and working area of ​​the circular main component 1, 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 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 of the arc 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 when the rotating pressing block 3 is attached to the baffle, there is also a rotating space between it and the circular main component 1. The rotating pressing block 1 is rotated clockwise with the arc groove 19 as the center of the circle, so that the upper arc-shaped protrusion 21 of the rotating pressing block 3 lifts the arc-shaped rotating fastener 2 and rotates downward to the bottom edge of the circular main component, and then the arc-shaped rotating fastener 2 can be rotated downward to make one side of the circular main component 1 open, and then the connecting device can be removed or installed. In this embodiment, the rotating pressing block 3 is in a semi-arc shape, which is consistent with the arc surface of the circular main component, and the arc plate at the lower end corresponds to the rotation space left by the arc surface of the circular main component 1 and the baffle 7.

[0024] like Figure 5 , 6As shown, the arc-shaped rotating fastener 2 is arranged at the opening of the circular main component 1, and circular holes with the same diameter as that on the circular main component 1 are provided at both ends of the arc-shaped rotating fastener 2 for the pin 4 to pass through. An arc-shaped groove 20 is provided at the lower end of the arc-shaped rotating fastener, corresponding to the upper arc-shaped protrusion 21 of the rotating pressing block 3. A buckle 23 is also provided on the same side of the arc-shaped groove 20 of the arc-shaped rotating fastener 2, and the buckle 23 extends and bends toward the inside of the circular main component 1, and is movably buckled with the end of the circular main component 1 to limit the rotation of the arc-shaped rotating fastener 2, thereby limiting the opening and closing of the disassembly and assembly area.

[0025] like Figure 7 , 8 As shown, the rotating pressure block 3 is arranged on the pressure block base 5, and the rotating pressure block 3 includes an upper arc-shaped protrusion 21 and a lower arc-shaped protrusion 22. The upper arc-shaped protrusion 21 and the lower arc-shaped protrusion 22 are arranged parallel to each other. The surface of the upper arc-shaped protrusion 21 is in close contact with the arc-shaped rotating fastener 2, and the surface of the lower arc-shaped protrusion 22 corresponds to the arc-shaped groove 19 of the pressure block base 5.

[0026] The inner wall of the circular main component 1 is fixedly provided with ribs 6, which are arranged on both sides of the vertical plate 17 and fixedly connected to the pressure block base 5. The ribs 6 are fixedly connected to the inner wall of the circular main component 1 through the vertical plate 17 and the pressure block base 5 to strengthen the rigidity of the pressure block base 5, reduce the pressure generated by the rotating pressure block 3 pressing on the pressure block base 5, and reduce the large deformation caused by rotation.

[0027] It also includes a connecting bolt 8, which passes through the circular main component 1 and the rotating pressure block 3, and connects and fixes the rotating pressure block 3, the baffle 7 and the vertical plate 17 at the same time 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 angle code 10 and is fixedly connected to the angle code 10.

[0028] An embodiment of the present invention also provides a method for installing a detachable handrail, comprising the following steps: like Figure 5 As shown, firstly, the railing column 9 is connected to the angle brackets 10 provided at both ends of the handrail 12 by using the bolt assembly 11, and at the same time, the handrail 12 is temporarily put on the angle bracket 10, and the two ends of the handrail 12 are welded with a horizontal connecting plate 13 and a vertical connecting plate 14, and 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, and the vertical connecting plate 14 is closely attached to the vertical edge of the angle bracket 10, so that the horizontal connecting plate 13 is placed on the horizontal edge above the angle bracket 10, and the left and right positions of the connecting device are reserved. After adjusting the position of the handrail 12, the angle bracket 10 is connected to the vertical connecting plate 14 inside the handrail 12 by using a short screw 16.

[0029] When installing the connection device, the rotating pressing block 3 is opened clockwise along the arc direction of the circular main component 1, so that the arc-shaped rotating fastener 2 is also rotated downward in the clockwise direction, and then the circular main component 1 and the arc-shaped rotating fastener 2 are in an open state, that is, the disassembly and assembly space on the left side of the circular main component 1 is opened, and the connection device is inserted into the angle code 10. The vertical plate 17 set inside the circular main component 1 is tightly attached to the vertical edge of the angle code 10, and the top of the angle code 10 is abutted against the horizontal plate 18 set on the top of the vertical plate 17. Then, the rotating pressing block 3 is rotated counterclockwise, thereby driving the arc-shaped rotating fastener 2 to rotate counterclockwise along the upper arc-shaped protrusion 21 set on the rotating pressing block 3, so that the circular main component 1 and the arc-shaped rotating fastener 2 are in a closed state. The circular main component 1, the rotating pressure block 3 and the angle code 10 are connected together by connecting bolts 8 to prevent the circular main component 1 and the rotating pressure block 3 from moving relative to each other, and to fix the connecting device on the angle code 10, thereby completing the installation of the connecting device and the handrail 12 on the railing column 9.

[0030] When disassembling the connection device and the handrail, first unscrew the connection bolt 8, and then bend the rotating pressing block 3 clockwise along the arc direction of the circular main component 1 to make the circular main component 1 and the arc-shaped rotating fastener 2 open. At this time, remove the connection device from the angle code 10. After that, unscrew the bolt assembly 11, and remove the handrail 12 and the angle code 10 from the railing column 9, completing the disassembly of the connection device and the handrail on the railing column.

[0031] The combined handrail form is adopted, and the handrail is divided into three parts, with a conventional circular handrail in the middle and detachable handrail connection devices at both ends. The detachable handrail connection device consists of a circular main component, an arc-shaped rotating fastener, and a rotating pressure block. By pressing or breaking the rotating pressure block, the circular main component can be closed or opened, so that the handrail can be installed and removed more conveniently, and the handrail will not be locally deformed during the installation and removal process.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
