Description

Technical Field

[0001] The utility model relates to the technical field of handrails, in particular to a handrail. Background Art

[0002] A handrail generally refers to a column standing on the ground or on the walkway on both sides of the stairs. It is a supporting and connecting accessory that serves to connect the upper and lower parts. It not only allows people to have a support when going up and down the stairs, but also avoids the danger of falling down the stairs, so that the entire staircase remains in orderly operation. A handrail, as the name suggests, is a horizontal bar, and there are also curved styles in some corner areas. In other words, when people go up and down the stairs, the part that they hold on to is called a handrail. It is used to support our body and is most often in contact with our body.

[0003] The handrail of the prior art is composed of a horizontal bar, a vertical bar and a rotating shaft, and the lower end of the rotating shaft and the vertical bar are welded. Generally, the horizontal bar, the vertical bar and the rotating shaft are all round tubes. Therefore, before welding, the welding points of the rotating shaft and the lower end of the vertical bar need to be cut at a 45° bevel. Otherwise, the angle between the horizontal bar and the vertical bar will not be perpendicular after welding, resulting in large assembly errors of the handrail and an unsightly appearance.

[0004] The 45° bevel needs to be completed by cutting and grinding. During the design phase, it is necessary to leave a margin for the pivot and vertical rod, and the size cannot be completely determined. The handrail cannot be installed in one go, and the pivot and vertical rod need to go through multiple grinding and trial installation processes, and the installation efficiency of the handrail is very low. Utility Model Content

[0005] The purpose of the utility model is to provide a handrail railing, which has the purpose of realizing rapid deployment and folding of the horizontal bar, is easy to operate, and effectively reduces the process of multiple grinding and trial installation of the vertical bars and rotating shafts of the handrail railing. The handrail can be installed directly, which reduces the time for repeated modifications and simplifies the installation process.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a handrail, including a walkway, a plurality of connecting parts are arranged on the back of the walkway, a plurality of limiting parts are arranged on the front end surface of the walkway, a rotating shaft is rotatably connected between the connecting parts and the limiting parts located on the same axis, the plurality of rotating shafts are connected to the bottom ends of the plurality of vertical rods through the plurality of bent pipes, a cross bar is arranged on the top ends of the plurality of vertical rods, and a limiting slot is arranged on the leftmost limiting part.

[0007] In order to reduce the process of multiple grinding and trial installation of the vertical rod and the rotating shaft, as a preferred handrail of the utility model, the bent pipe and the vertical rod are integrally formed.

[0008] In order to reduce the process of multiple grinding and trial installation of the vertical rod and the rotating shaft, as a preferred handrail of the utility model, the bent pipe and the rotating shaft are integrally formed.

[0009] In order to reduce the process of multiple grinding and trial installation of the vertical rod and the rotating shaft, as a preferred handrail of the utility model, the two ends of the bent pipe are respectively connected to the rotating shaft and the vertical rod.

[0010] In order to allow the horizontal bar and the vertical bar to be foldable and movable, as a preferred handrail of the utility model, the top ends of the plurality of vertical bars are movably connected with pipe clamps, and the horizontal bar is detachably connected to the plurality of pipe clamps.

[0011] In order to support the cross bar, as a preferred handrail of the utility model, a connecting plate is fixedly connected to the right side of the front end face of the walkway, and the outer walls of the connecting plate are fixedly connected with supporting parts except the limiting part located on the far left of the plurality of limiting parts.

[0012] In order to facilitate disassembly and assembly, as a preferred handrail of the utility model, the connecting member and the limiting member are both detachably connected to the walkway.

[0013] In order to transfer the vertical rod, as a preferred handrail of the utility model, the bend is 90 degrees.

[0014] For the movable limiting member, as a preferred handrail of the present invention, the limiting member on the far left is a hinge structure.
