[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a modular prefabricated staircase that can be quickly assembled, comprising an installation component 1, a locking block 7 fixedly connected to the top of the installation component 1, an installation plate 2 provided on the top of the installation component 1, and a slot 8 provided at the bottom of the installation plate 2. The locking block 7 can be inserted into the slot 8 to limit and fix the installation component 1 and the installation plate 2. At the same time, a small bolt is used to pass through the installation component 1 and into the installation plate 2, thereby limiting and fixing the installation component 1 and the installation plate 2. A protective component 3 is provided on the side of the installation component 1. Component 3 includes a fixing hole 301, which is located on the side of the mounting component 1. A support rod 302 is inserted into the fixing hole 301. A handrail 303 is provided on the top of the support rod 302. A mounting hole 304 is provided at the bottom of the handrail 303. The support rod 302 is inserted into the mounting hole 304. The mounting holes 304 are evenly distributed in a linear array at the bottom of the handrail 303, which makes the handrail 303 more stable during installation. A pedal 5 is provided on the back of the mounting component 1. A mounting assembly 4 is provided on the back of the mounting component 1.

[0020] Reference Figure 1 , Figure 3 and Figure 5The mounting component 4 includes an upper guide 402, which is fixedly connected to the back of the mounting component 1. The upper guide 402 and the lower guide 403 are symmetrically arranged around the center of the embedding groove 401. The ends of the upper guide 402 and the lower guide 403 are provided with arc-shaped surfaces. When the pedal 5 is installed, the outer surface of the pedal 5 will contact the bottom of the upper guide 402. Then, the pedal 5 is pushed, which allows the embedding 405 to be inserted into the embedding groove 401, so that the pedal 5 can be installed stably and quickly. The lower guide 403 is fixedly connected to the back of the mounting component 1. The back of the mounting component 1 has an embedding groove 401, and the embedding 405 is inserted into the embedding groove 401. The embedding grooves 401 are evenly distributed in a linear array on the back of the mounting component 1, so that the pedal 5 can be evenly installed on the back of the mounting component 1.

[0021] A limiting hole 404 is provided on the side of the mounting component 1 away from the protective component 3. An insert 405 is fixedly connected to the side of the pedal 5. A connecting plate 406 is fixedly connected to the side of the pedal 5. A large bolt 407 is threadedly connected to the side of the connecting plate 406. After the pedal 5 is installed stably, the large bolt 407 is passed through the connecting plate 406 and the large bolt 407 is threadedly connected to the inside of the limiting hole 404, thereby effectively realizing the limiting function of the pedal 5.

[0022] Reference Figure 1 , Figure 2 and Figure 5 The upper surface of the pedal 5 is provided with a stacking component 6, which includes a groove 601. The groove 601 is formed on the upper surface of the pedal 5, and its position corresponds to the position of the fixing block 602. The size of the groove 601 is adapted to the size of the fixing block 602. During the stacking and transportation of the pedals 5, the fixing block 602 at the bottom of one pedal 5 will be inserted into the groove 601 on the upper surface of another pedal 5, thereby ensuring that the pedals 5 have higher stability during stacking and transportation. The fixing block 602 is fixedly connected to the bottom of the pedal 5, and a protrusion 603 is fixedly connected to the outer surface of the fixing block 602. The protrusion 603 is semi-circular and made of rubber. After the fixing block 602 is inserted into the groove 601, the outer surface of the protrusion 603 will contact the inner wall of the groove 601, thereby making the pedals 5 more stable during stacking.

[0023] Working principle: First, the mounting plate 2 is precisely engaged with the top of the mounting component 1 through the bottom slot 8, and then fixed with small bolts to complete the fixed connection between the mounting component 1 and the mounting plate 2, thus constructing the basic load-bearing structure of the staircase. Next, the support rod 302 is inserted into the fixing hole 301 on the side of the mounting component 1, and then the mounting hole 304 at the bottom of the handrail 303 is aligned with the top of the support rod 302 for insertion. The linear array of mounting holes 304 ensures that the handrail 303 is firmly installed.

[0024] Then, the pedal 5 is pushed so that its outer surface contacts the bottom of the upper guide 402, and with the cooperation of the lower guide 403, the insert 405 is smoothly inserted into the linearly arrayed insert grooves 401 on the back of the mounting piece 1. Afterwards, a large bolt 407 is threaded through the connecting plate 406 on the side of the pedal 5 and into the corresponding limiting hole 404 on the side of the mounting piece 1 to achieve precise positioning and fixation of the pedal 5.

[0025] In addition, when stacking and transporting pedals 5, the fixing block 602 at the bottom of one pedal 5 needs to be aligned with the groove 601 on the upper surface of another pedal 5 and inserted to complete the orderly stacking of multiple pedals 5 for convenient storage and transportation.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
