Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an assembled temporary handrail for stairs. Background Art

[0002] Before decoration, an unfinished house usually has only stairs but no handrails. When construction workers are working in an unfinished house, they need to frequently go up and down the stairs without handrails, so there is a risk of falling from the stairs.

[0003] In order to avoid the risk of falling from the stairs, fences are usually set up next to the stairs to warn people passing by and prevent them from falling. However, such fences usually only serve as a reminder. Once people accidentally lean on the fence, they may fall from the stairs together with the fence. Therefore, a temporary handrail that can play a protective effect is needed to avoid this risk. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes an assembled temporary stair handrail, which can be temporarily installed on the stairs of a rough house, so as to prevent people from accidentally falling from the stairs when passing by.

[0005] The technical solution to achieve the purpose of the utility model is: an assembled temporary handrail for stairs, comprising a support plate, a vertical rod fixedly connected to the support plate, a fixing assembly provided on the support plate, the fixing assembly comprising a side rod, a bottom plate, a sliding rod, a thread and a limiting ring, the side rod being fixedly connected to the support plate, the bottom plate being rotatably connected to the side rod, the sliding rod being slidably connected to the vertical rod, and the sliding rod being fixedly connected to the side rod, the thread being opened at the bottom end of the vertical rod, the limiting ring being spirally connected to the thread, and a connecting assembly being provided on the vertical rod.

[0006] Preferably, the connecting assembly comprises a bracket, a rotating block and a through hole, the bracket is fixedly connected to the top end of the vertical rod, the rotating block is rotatably connected to the inside of the bracket, and the through hole is opened on the rotating block.

[0007] Preferably, the connecting assembly further comprises an insert rod, and the insert rod passes through the through hole.

[0008] Preferably, the insertion rod is adapted to the through hole, and the insertion rod is in a "T" shape.

[0009] Preferably, the side rod is in an "L" shape, and the bottom plate is rotatably connected to one end of the side rod.

[0010] Compared with the prior art, the utility model has the following significant advantages:

[0011] First: In the utility model, the temporary handrail can be taken to the stairs and placed on the edge of the stairs so that the side rods are located outside the stairs. The handrail is then translated and moved closer to the stairs until the support plate is on the upper surface of the stairs, that is, the surface of the step, and the bottom plate is located at the bottom of the stairs. The support plate is then stepped on to keep the entire handrail stable. The limiting ring is then rotated to move the limiting ring upward. When the limiting ring moves upward, it will drive the sliding rod to move upward together, thereby driving the side rods and the bottom plate to move upward together until the bottom plate contacts the bottom of the stairs. Since the bottom plate can rotate on the side rods, the upward movement of the limiting ring will eventually cause the bottom plate to tilt to fit the bottom surface of the stairs. At this time, the limiting ring is continued to be screwed upward, so that the limiting ring cannot rotate and is clamped with the sliding rod. At this time, it is equivalent to the supporting plate and the bottom plate clamping the stairs together, thereby fixing the entire handrail on the stairs.

[0012] Second: In the present invention, a handrail is installed every several steps through the same operation method. When all the handrails are installed, the insertion rod is inserted into the through hole on the rotating block on each handrail in turn. The insertion rod is "T" shaped, so one end of it cannot pass through the through hole. Therefore, it is necessary to insert the insertion rod through each through hole in turn starting from the top, and the end of the insertion rod will be stuck on the top rotating block. Under the influence of gravity, the insertion rod will remain fixed and will not loosen. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides an assembled temporary stair handrail through improvement. The technical solution of the utility model is:

[0022] like Figure 1-Figure 4 As shown, an assembled temporary handrail for stairs includes a support plate 1, to which a vertical rod 2 is fixedly connected, and a fixing assembly 4 is arranged on the support plate 1, and the fixing assembly 4 includes a side rod 41, a bottom plate 42, a sliding rod 43, a thread 44 and a limiting ring 45, the side rod 41 is fixedly connected to the support plate 1, the bottom plate 42 is rotatably connected to the side rod 41, the sliding rod 43 is slidably connected to the vertical rod 2, and the sliding rod 43 is fixedly connected to the side rod 41, the thread 44 is opened at the bottom end of the vertical rod 2, the limiting ring 45 is spirally connected to the thread 44, and a connecting assembly 3 is arranged on the vertical rod 2, the support plate 1 and the bottom plate 42 are equivalent to clamps, which can be clamped on each step on the stairs 5, thereby serving as a temporary handrail.

[0023] Furthermore, the connecting assembly 3 includes a bracket 31 , a rotating block 32 and a through hole 33 . The bracket 31 is fixedly connected to the top of the vertical rod 2 . The rotating block 32 is rotatably connected to the inside of the bracket 31 . The through hole 33 is opened on the rotating block 32 .

[0024] Furthermore, the connecting component 3 also includes an insert rod 34, which passes through the through hole 33. After the insert rod 34 is installed, all the handrails will be connected together. When the insert rod 34 is hit, the impact force will also be distributed to each handrail. Therefore, all the handrails are equivalent to being connected as a whole and are not easy to fall off due to impact, etc., thereby being able to provide good protection and preventing people from falling from the stairs 5.

[0025] Furthermore, the insertion rod 34 is adapted to the through hole 33, and the insertion rod 34 is in a "T" shape. When all the handrails are installed, the insertion rod 34 is inserted into the through hole 33 on the rotating block 32 on each handrail in turn. The insertion rod 34 is in a "T" shape, so one end of it cannot pass through the through hole 33. Therefore, the insertion rod 34 needs to pass through each through hole 33 in turn starting from the top, and the end of the insertion rod 34 will be stuck on the top rotating block 32. Under the influence of gravity, the insertion rod 34 will remain fixed and will not loosen.

[0026] Furthermore, the side rod 41 is in an “L” shape, and the bottom plate 42 is rotatably connected to one end of the side rod 41 .

[0027] The specific working method is: first, take the temporary handrail to the stair 5, place it on the edge of the stair 5, make the side rod 41 outside the stair 5, then translate the handrail and move it close to the stair 5 until the support plate 1 is on the upper surface of the stair 5, that is, the surface of the step, and the bottom plate 42 is at the bottom of the stair 5, then step on the support plate 1 to keep the entire handrail stable, and then rotate the limiting ring 45 to move the limiting ring 45 upward. When the limiting ring 45 moves upward, it will drive the sliding rod 43 to move upward together, thereby driving the side rod 41 and the bottom plate 42 to move upward together until the bottom plate 42 contacts the bottom of the stair 5. Since the bottom plate 42 can rotate on the side rod 41, the upward movement of the limiting ring 45 will eventually cause the bottom plate 42 to tilt to fit the stair 5. The bottom surface, at this time, continue to screw the limit ring 45 upward, the limit ring 45 cannot rotate, and is clamped between the sliding rod 43, which is equivalent to the support plate 1 and the bottom plate 42 clamping the stair 5 together, so that the entire handrail is fixed on the stair 5, and a handrail is installed every several steps through the same operation method. When all the handrails are installed, the insertion rod 34 is inserted into the through hole 33 on the rotating block 32 on each handrail in turn. The insertion rod 34 is "T" shaped, so one end of it cannot pass through the through hole 33, so it is necessary to insert the insertion rod 34 from the top through each through hole 33 in turn, and the end of the insertion rod 34 will be stuck on the top rotating block 32, and under the influence of gravity, the insertion rod 34 will remain fixed and will not loosen.

[0028] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
