The number of the plurality of wall mounting components is the same as that of the plurality of treads, and the plurality of treads are located between the wall mounting components and the handrail. First slots and second slots are respectively opened at both ends of the tread. A connection component for connecting the wall mounting component is provided at the bottom of the first slot. A plurality of second insertion plates for connecting the treads are fixed on the surface of the handrail, and the second insertion plates can be inserted into the second slots.
[0006] Further, the wall mounting component includes a mounting plate. Mounting holes are opened on the mounting plate, and the mounting plate is fixed on the wall by bolts. A first insertion plate is fixed on the surface of the mounting plate, and the first insertion plate can be inserted into the first slot.
[0007] Further, sinking grooves are opened on both sides of the outer side wall of the tread and located on both sides of the first slot, and the mounting bolts of the mounting plate can be clamped into the sinking grooves.
[0008] Further, the connection component includes a groove opened below the first slot. A through hole is opened between the groove and the first slot. A plug rod is penetrated and slidably connected inside the through hole. A end plate is fixedly connected to the bottom end of the plug rod. A tension spring is fixedly connected between the upper surface of the end plate and the inner top wall of the groove. A jack for inserting the plug rod is opened on the lower surface of the first insertion plate.

Specific Embodiments
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] As Figures 1-4 shown, it relates to a prefabricated staircase structure, including a handrail 1, a plurality of treads 2 and a plurality of wall mounting components 3. The number of the plurality of wall mounting components 3 is the same as that of the plurality of treads 2, and the plurality of treads 2 are located between the wall mounting components 3 and the handrail 1. First slots 21 and second slots 23 are respectively formed at both ends of the tread 2. A connecting component 4 for connecting the wall mounting component 3 is provided at the bottom of the first slot 21. A plurality of second insertion plates 5 for connecting the tread 2 are fixed on the surface of the handrail 1, and the second insertion plates 5 can be inserted into the second slots 23.
[0023] The wall mounting component 3 includes a mounting plate 31. Mounting holes are formed in the mounting plate 31, and the mounting plate 31 is fixed to the wall by bolts. A first insertion plate 32 is fixed on the surface of the mounting plate 31, and the first insertion plate 32 can be inserted into the first slot 21.
[0024] After first fixing the mounting plate 31 to the wall by bolts, the first slot 21 on the tread 2 can be sleeved on the surface of the first insertion plate 32, and the tread 2 is preliminarily supported and fixed by the first insertion plate 32.
[0025] Sunk grooves 22 are formed on both sides of the first slot 21 on the outer side wall of the tread 2, and the mounting bolts of the mounting plate 31 can be caught in the sunk grooves 22.
[0026] By providing the sunk grooves 22, the bolt heads for fixing the mounting plate 31 can be received in the sunk grooves 22, making it more beautiful.
[0027] The connecting component 4 includes a groove 41 formed below the first slot 21. A through hole 42 is formed between the groove 41 and the first slot 21. A plug rod 43 is penetrated and slidably connected inside the through hole 42. A end plate 44 is fixedly connected to the bottom end of the plug rod 43. A tension spring 45 is fixedly connected between the upper surface of the end plate 44 and the inner top wall of the groove 41. A jack for inserting the plug rod 43 is formed on the lower surface of the first insertion plate 32.
[0028] After the first insertion plate 32 is inserted into the first slot 21, the tension spring 45 will pull the end plate 44 and the plug rod 43 to move upward, so that the plug rod 43 is inserted into the jack on the lower surface of the first insertion plate 32, thereby realizing the fixation of the first insertion plate 32 in the first slot 21.
[0029] A pull ring 46 is fixedly connected to the lower surface of the end plate 44.
[0030] By pulling the pull ring 46 downward, the end plate 44 can be driven to move downward, so that the insertion rod 43 moves downward and disengages from the first slot 21.
[0031] A light strip card slot 24 is formed in the lower surface of each pedal 2.
[0032] An LED light strip can be installed inside the light strip card slot 24, so that the light strip can be hidden and looks more beautiful.
[0033] A bottom plate 6 is fixed to the bottom end of the handrail 1, and a top plate 7 is fixed to the top end of the handrail 1. The bottom plate 6 and the top plate 7 are respectively fixed to the ground and the wall by bolts.
[0034] Working principle: First, each mounting plate 31 is fixed to the wall by bolts, and then the pedal 2 is installed. When installing the pedal 2, first pull the lower pull ring 46 to make the insertion rod 43 move downward. Then, the first slot 21 of the pedal 2 is sleeved on the first insertion plate 32. Subsequently, after releasing the pull ring 46, the tension spring 45 pulls the insertion rod 43 to insert into the jack on the lower surface of the first insertion plate 32, realizing the preliminary support and fixation of the pedal 2. When all the pedals 2 are fixed, move the handrail 1 and make several second insertion plates 5 on the handrail 1 respectively insert into several second slots 23 on the pedals 2. Finally, install and fix the bottom plate 6 and the top plate 7 by bolts.
