DETAILED DESCRIPTION

[0024] The present application is described in detail below in conjunction with the accompanying drawings and examples.

[0025] Examples:

[0026] A detachable universal baffle for stairs, such as Figure 1 and Figure 3As shown, the assembly includes a modular handrail 1, several intermediate support columns 2, and several end support columns 3. The end support columns 3 are positioned between two modular handrails 1 at different angles. The intermediate support columns 2 are located between the two end support columns 3 to support the middle portion of the modular handrail 1. The top of the intermediate support column 2 slides along the length of the modular handrail 1 and is rotatably connected to the modular handrail 1. The top of the intermediate support column 2 is detachably connected inside the modular handrail 1. The modular handrail 1 includes several handrail units 4 detachably connected along its length. The end support columns 3 have openings... The modular handrail 1 includes several grooves 5 for accommodating handrail units 4 of arbitrary lengths. The handrail units 4 are inserted horizontally or at an angle into the grooves 5. The modular handrail 1 comprises several handrail units 4 detachably connected along its length, and the end support column 3 has several grooves 5 for accommodating handrail units 4 of arbitrary lengths. This allows for coarse adjustment of the length of the modular handrail 1 by adding or reducing the number of handrail units 4, and further fine adjustment of the length of the modular handrail 1 by adjusting the length of the handrail units 4 embedded in the grooves 5. This achieves the effect of arbitrarily adjusting the length of the modular handrail 1. The top of the support column 2 slides along the length of the combined handrail 1, thereby adjusting the distance between the intermediate support columns 2. This facilitates the creation of stair railings with varying distances between the intermediate support columns 2. The top of the intermediate support column 2 is detachably connected to the combined handrail 1. When the spacing between the intermediate support columns 2 is large or there are many intermediate support columns 2, they can be removed to achieve the desired number. The handrail unit 4 is horizontally inserted into the groove 5. Combined with the combined handrail 1 with its adjustable length and the intermediate support columns 2 with their adjustable spacing, a highly versatile horizontal stair railing can be created. The top of column 2 is rotatably connected to the combined handrail 1, thereby adjusting the angle between the combined handrail 1 and the intermediate support column 2, so that the intermediate support column 2 is set vertically, while the combined handrail 1 is set at an angle consistent with the inclination angle of the staircase. It can be installed in the middle section of the staircase. Combined with the adjustable spacing of the intermediate support column 2, it can adapt to the ascending steps of any width. Thus, after the handrail unit 4 is inserted into the groove 5 at an angle, a highly versatile inclined staircase edge can be made. In summary, the staircase edge has high versatility and can be used on different staircases, with high reusability.

[0027] like Figure 6 As shown, each handrail unit 4 includes a main body 13 and a snap-in part 14. The main body 13 has a slot 15 for receiving the snap-in part 14 of another handrail unit 4. After the snap-in part 14 is snapped into the slot 15, the snap-in part 14 and the main body 13 are fixed by bolts to achieve detachable connection between adjacent handrail units 4. The length of the main body 13 can be made in various sizes to facilitate adjustment of the length of the combined handrail 1.

[0028] like Figure 5 and Figure 7As shown, the combined handrail 1 also includes a spacing synchronization adjustment component, which is used to synchronously adjust the intermediate support column 2. Specifically, the spacing synchronization adjustment component is a scissor mechanism, which includes several cross pivots 6, several connecting arms 7, and several pins 16. The cross pivots 6 are the central axis in the length direction of the scissor mechanism. During the extension and retraction of the scissor mechanism, the cross pivots 6 move along the length direction of the combined handrail 1, and the inner walls of the handrail unit 4 are provided with sliding grooves 18 to accommodate the sliding of the cross pivots 6. The pins 16 are located on the upper and lower sides of the scissor mechanism, which play a role in the relative rotation between the connecting arms 7. The connecting arms 7 and the cross pivots 6 are detachably rotatably connected. Specifically, the main body 13 includes two half-shells 17, which are detachably connected by bolts. After the two half-shells 17 are disassembled, the connecting arms 7 and the cross pivots 6 that need to be disassembled can be taken out. One end of the scissor mechanism is rotatably connected to one of the outermost handrail units 4. Specifically, the scissor mechanism also includes A fixed pivot 19 is located at one end and rotatably connected to the outermost handrail unit 4. The top of the middle support column 2 is detachably rotatably connected to the cross pivot 6. Specifically, the cross pivot 6 passes through the top of the middle support column 2. After the two half-shells 17 are disassembled, the middle support column 2 can be removed. When the scissor mechanism extends and retracts, it can maintain the equal distance between each cross pivot 6, so that several middle support columns 2 can be adjusted synchronously when adjusting the distance, which is more convenient and faster. The top of the middle support column 2 is detachably rotatably connected to the cross pivot 6, so that the middle support column 2 can be fixed on several cross pivots 6. Therefore, multiple cross pivots 6 can fix a small number of middle support columns 2, so that the vertical distance of the scissor mechanism does not need to be large to achieve a large adjustment of the distance between adjacent middle support columns 2. The connecting arm 7 is detachably rotatably connected to the cross pivot 6, so that the length of the scissor mechanism can be adjusted according to the length of the combined handrail 1, improving the versatility of the stair railing.

[0029] like Figure 2 and Figure 5 As shown, the combined handrail 1 is provided with a pre-positioning component for fixing the cross pivot 6. Specifically, the cross pivot 6 has a threaded section 8 that extends through to the outside of the handrail unit 4. The handrail unit 4 has an adjustment groove 12 to accommodate the sliding of the threaded section 8. The pre-positioning component is a fastening cap 9 that is threadedly connected to the threaded section 8. The fastening cap 9 is fixed to the surface of the handrail unit 4 by friction. The outer edge of the fastening cap 9 has an annular anti-slip protrusion. By fixing the cross pivot 6 with the pre-positioning component, the entire scissor mechanism is fixed, thereby fixing the position of the intermediate support column 2. During installation, the position of the intermediate support column 2 will not change, which is convenient for installation. When the scissor mechanism is adjusted, the threaded section 8 moves along the length direction of the adjustment groove 12. After adjustment, the fastening cap 9 is tightened, and the threaded section 8 is fixed by the friction between the fastening cap 9 and the handrail unit 4, thereby achieving the fixing effect of the pre-positioning component.

[0030] likeFigure 2 and Figure 4 As shown, the end support column 3 is slidably connected to the gate plate 10 located on the upper and lower sides of the groove 5. The gate plate 10 slides and is used to abut the top or bottom surface of the handrail unit 4. The groove 5 accommodates the insertion of the combined handrail 1 at various angles. The space reserved on both sides of the groove 5 can be closed by sliding the gate plate 10. By closing the groove 5, it achieves the effects of aesthetics and dust prevention, and can also reinforce the combined handrail 1. Moreover, the sliding method of the gate plate 10 can close the space of any size above and below the handrail unit 4 and the groove 5, realizing the height versatility of the stair handrail.

[0031] like Figure 2 and Figure 4 As shown, a fixing plate 11 is rotatably connected to one end of the gate 10 facing the center of the opening of the groove 5. The handrail unit 4 embedded in the groove 5 is fixed to the fixing plate 11. Specifically, the top and bottom surfaces of the handrail unit 4 embedded in the groove 5 are drilled and riveted to the fixing plate 11. The fixing plate 11 and the gate 10 are rotatably connected and riveted to the handrail unit 4, thereby fixing the gate 10 and the handrail unit 4. The fixing plate 11 is rotatably connected to the gate 10, thereby adapting to the combined handrail 1 inserted into the groove 5 at different angles. The top and bottom surfaces of the handrail unit 4 are drilled and riveted to the fixing plate 11, thereby enabling the handrail unit 4 to be fixed to the fixing plate 11 at any position. The combined handrail 1 can be fixed to the fixing plate 11 at different depths when inserted into the groove 5, realizing the height versatility of the stair handrail.
