[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0032] See also Figure 1-6 The utility model provides a technical solution: a handrail installation structure for an assembled spiral staircase, comprising a mounting column 1, a mounting plate 2, a fixing block 3, a side block 4, a connecting block 5, a movable bracket 6, a fixing pin 7, a fixing column 8, a fixing sleeve 9, a handrail rod 10, a mounting mechanism 11, a mounting sleeve 12, a spring 13, a movable block 14, a pull rod 15, a connecting pin 16 and a silicone soft sleeve 17.

[0033] When using the handrail installation structure for assembled spiral staircases, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lower end of the mounting column 1 is fixedly connected with a mounting plate 2. First, the mounting column 1 drives the mounting plate 2 to engage on the stair step, and the fixing block 3 is fixed on the stair step. The mounting plate 2 and the fixing block 3 are connected by a slot, so as to facilitate the rapid positioning between the mounting column 1 and the stair step. Then, by pulling the movable bracket 6, the movable bracket 6 slides between the connecting block 5, and the movable bracket 6 moves between the fixing column 8. The side of the movable bracket 6 is fixedly connected with a fixing pin 7. The movable bracket 6 drives the fixing pin 7 to extend and retract, so that the fixing pin 7 engages on the side block 4, so as to facilitate the limiting of the mounting plate 2 and the fixing block 3. The mounting column 1 can be fixedly installed at the corresponding position on the stair step. Then, by rotating the fixing sleeve 9 threadedly connected to the outer surface of the fixing column 8, the fixing sleeve 9 is fitted on the side of the connecting block 5. The movable bracket 6 can be limited by the fixing sleeve 9, so as to prevent the fixing pin 7 from loosening with the side block 4, thereby improving the tightness of the connection between the mounting plate 2 and the fixing block 3.

[0034] After the mounting column 1 is fixed on the stair step, Figure 1 , Figure 5 and Figure 6As shown, the mounting mechanism 11 is symmetrically arranged at the left and right ends of the handrail 10, and the mounting mechanism 11 includes mounting sleeves 12 fixedly connected to the left and right ends of the handrail 10, a spring 13 arranged inside the handrail 10, a movable block 14 fixedly connected to the movable end of the spring 13, a pull rod 15 fixedly connected to the front and rear ends of the movable block 14, and a connecting pin 16 for positioning. By pulling the pull rod 15, the pull rod 15 and the handrail 10 can move, and the pull rod 15 drives the movable block 14 and the handrail 10 to slide, and at the same time, the movable block 14 drives the connecting pin 16 and the mounting sleeve 12 to slide, so that the connecting pin 16 and the handrail 10 can be telescoped;

[0035] Then, the installation sleeve 12 is sleeved on the outside of the installation column 1 through the handrail rod 10, and the handrail rod 10 is pulled downward. The handrail rod 10 drives the installation sleeve 12 to move on the outside of the installation column 1. When it moves to the corresponding position, the pull rod 15 is directly released. At this time, the spring 13 restores its elastic deformation, driving the movable block 14 to slide with the handrail rod 10, so that the movable block 14 drives the connecting pin 16 to engage with the corresponding position in the middle of the installation column 1, thereby facilitating the fixing of the installation sleeve 12 at the corresponding position in the middle of the installation column 1, facilitating the connection between the handrail rod 10 and the installation column 1, and then repeating the above operation to install the handrail rod 10 in the middle of the installation column 1 at equal intervals, forming a shape as shown in FIG. Figure 1 In the state shown, the handrail can be assembled very conveniently. After the installation is completed, the silicone soft cover 17 can be put on the upper end of the installation column 1. The overall structural design is relatively simple and convenient for disassembly and assembly.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
