DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-5 This application is described in further detail.

[0044] An embodiment of the present application discloses an assembled stair guardrail.

[0045] Embodiment 1

[0046] See also Figure 1 and Figure 2 The assembled stair guardrail includes a vertical pole 1 and a fixing assembly 2. The vertical pole 1 has a plurality of vertical poles and is evenly spaced on the steps of the staircase. The fixing assembly 2 includes a fixing plate 21 and a fixing bolt 22. The fixing plate 21 corresponds to the vertical pole 1 one by one and is fixed to the bottom of the vertical pole 1. There are a plurality of fixing bolts 22 and they are respectively penetrated on the fixing plates 21. The fixing bolts 22 surround the vertical pole 1. The fixing bolts 22 are threadedly connected to the steps of the staircase, so that the vertical pole 1 can be detachably fixed on the steps of the staircase.

[0047] The assembled stair guardrail also includes support plates 3, which are arranged in groups and spaced apart from each other on the outer peripheral side of the upright pole 1. Each group of support plates 3 has two support plates 3, which are fixed on the outer peripheral side of the upright pole 1, and the two support plates 3 in the same group are arranged at an angle of 45 degrees. When the upright pole 1 is installed, the inclination direction of the support plates 3 is adapted to the inclination direction of the stairs, and the support plates 3 between adjacent upright poles 1 are arranged relative to each other. A threaded hole 31 is formed on the support plate 3, and the threaded hole 31 is screwed in a direction perpendicular to the support plate 3.

[0048] The assembled stair guardrail further includes a support tube 4 and a connecting bolt 42. There are multiple support tubes 4, and each support tube 4 is placed on two adjacent support plates 3 at the same vertical height of two adjacent uprights 1. A through hole 41 is formed on the support tube 4, and the through hole 41 corresponds to the threaded hole 31 one by one. The connecting bolt 42 is penetrated through the through hole 41. When the support tube 4 is placed on the support plate 3, the connecting bolt 42 is threadedly connected to the threaded hole 31, so that the support tube 4 and the support plate 3 are connected and fixed.

[0049] The implementation principle of an assembled stair guardrail in the first embodiment of the present application is:

[0050] When installing the stairs, firstly, each upright pole 1 is respectively installed and fixed on the steps of the stairs, so that the support plates 3 of adjacent upright poles 1 are in the same straight line. Then, the support tube 4 is placed on the adjacent support plates 3 of the adjacent upright poles 1, so that the through hole 41 is aligned with the threaded hole 31, and finally, the connecting bolt 42 is passed through the through hole 41 and then threadedly connected to the threaded hole 31, so as to realize the connection and fixation between the support tube 4 and the support plate 3, without using a large number of cross buckles for connection and fixation, thereby greatly simplifying the installation process and reducing the installation cost.

[0051] Embodiment 2

[0052] The difference between the second embodiment of the present application and the first embodiment is that: Figure 3 The support plate 3 includes a support ring 5 and a support sheet 51 . The support sheet 51 is fixedly connected to the outer peripheral side of the support ring 5 , and the threaded hole 31 is formed in the support sheet 51 .

[0053] The outer circumference of the upright pole 1 is formed with a threaded section, and the support ring 5 is threadedly connected to the threaded section on the outer circumference of the upright pole 1, so that the upper and lower positions of the support ring 5 can be adjusted. When in use, the upper and lower positions are adjusted by rotating the support ring 5, so that the upper and lower heights of the support pipe 4 can adapt to the construction environment.

[0054] The implementation principle of an assembled stair guardrail in the second embodiment of the present application is:

[0055] When installing the stairs, first adjust the position of the support ring 5 of each upright 1, then install the upright 1, and finally install the support pipe 4.

[0056] Embodiment 3

[0057] The difference between the third embodiment of the present application and the second embodiment is that: Figure 4 and Figure 5 The support plate 3 includes a support sleeve 61 , a support bar 62 , a support block 63 and a plug-in column 6 .

[0058] The support sleeve 61 is sleeved on the outer peripheral side of the vertical pole 1. There is friction between the inner peripheral side wall of the support sleeve 61 and the outer peripheral side wall of the vertical pole 1, which reduces the support sleeve 61 from sliding directly downward on the vertical pole 1 under the action of gravity. A guide block 612 is fixedly connected to the inner wall of the support sleeve 61, and a guide groove 12 is formed on the outer peripheral side of the vertical pole 1. The guide groove 12 extends in the vertical direction. The guide block 612 slides up and down in the guide groove 12 to guide the sliding trajectory of the support sleeve 61.

[0059] There are two support bars 62 and they are respectively arranged on the outer peripheral side of the support sleeve 61. The support bars 62 are long support column structures. Each group of support bars 62 has two and they are symmetrically fixed on the outer peripheral side of the support sleeve 61. There are multiple groups of support blocks 63, each group of support blocks 63 corresponds to a group of support bars 62, each support block 63 slides between the two support bars 62 in the same group, and the threaded hole 31 is formed in the support block 63.

[0060] The side walls of the two supporting bars 62 in the same group are respectively formed with slide grooves 622, which extend along the length direction of the supporting bars 62. The side walls of the supporting blocks 63 are fixedly connected with sliders 632 corresponding to the slide grooves 622. When in use, the sliders 632 slide in the slide grooves 622 to limit the supporting blocks 63 from being separated from between the two supporting bars 62 in the same group.

[0061] The plug-in column 6 is fixedly connected to the side of the support block 63 close to the support sleeve 61. The support sleeve 61 is formed with a connecting hole 611, which corresponds to the plug-in column 6 and is passed through by the plug-in column 6. The outer peripheral side of the vertical pole 1 is formed with a plug-in groove 11, and there are multiple plug-in grooves 11 and they are evenly spaced up and down. The plug-in column 6 passes through the connecting hole 611 and is plugged into the plug-in groove 11, so that the connection and fixation between the support sleeve 61 and the vertical pole 1 are realized.

[0062] A fixing pin 621 is slidably inserted into the support bar 62, and a fixing groove 631 is formed on the side wall of the support block 63. The fixing pin 621 is inserted into the fixing groove 631 to limit the support block 63 from moving away from the support sleeve 61; at the same time, when the fixing pin 621 is inserted into the fixing groove 631, the end of the fixing pin 621 away from the fixing groove 631 protrudes out of the support bar 62.

[0063] The implementation principle of an assembled stair guardrail in the third embodiment of the present application is:

[0064] When installing the stairs, first adjust the position of the support ring 5 of each upright pole 1. When adjusting, slide the support sleeve 61 up and down to the adjustment position so that the fixing pin 621 is aligned with the fixing groove 631, then slide the support block 63 so that the plug-in column 6 passes through the connecting hole 611 and is inserted into the plug-in groove 11, and then slide the fixing pin 621 to be inserted into the fixing groove 631. Then fix the upright pole 1, and finally install the support tube 4.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
