[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Combination Figure 1-4 As shown, this embodiment provides a prefabricated staircase for quick installation, including: a main body module 100.

[0026] The main body module 100 includes two symmetrically arranged ladder beams 110 , a plurality of locking members 120 installed in the inner cavity of the ladder beams 110 and extending out of the ladder beams 110 , and a plurality of pedals 130 embedded in the ladder beams 110 .

[0027] The ladder beam 110 is used to install the pedal 130 and plays a load-bearing role. Grooves 111 are arranged in an array at the top of the ladder beam 110. The pedal 130 includes a support plate 132 embedded in the groove 111 and a bottom plate 131 fixed to the top of the support plate 132. The support plate 132 is used to install the bottom plate 131 to ensure the stability of the bottom plate 131. At the same time, the support plate 132 is connected to the ladder beam 110 in a mosaic manner, which is convenient for installation and disassembly, thereby increasing the speed of installing the pedal 130.

[0028] A circular groove 112 is opened on the inner wall of one side of the groove 111, and a locking piece 120 is arranged in the circular groove 112. The locking piece 120 includes an insertion rod 121 movably arranged in the circular groove 112 and extending into the groove 111, a spring 122 fixed at one end of the insertion rod 121, a base 123 fixed at one end of the insertion rod 121 and extending out of the ladder beam 110, and a movable handle 124 whose end is hinged to the base 123.

[0029] A slot 1321 is provided on the outer surface of the support plate 132, and the insertion rod 121 is engaged in the slot 1321, which is used to fix the support plate 132 and ensure the stability of the connection between the support plate 132 and the ladder beam 110. One end of the spring 122 is fixed to the end of the insertion rod 121, and the other end is fixed to the inner bottom wall of the circular groove 112, which is used to ensure that the insertion rod 121 is always engaged in the slot 1321.

[0030] The base 123 is fixed on the insertion rod 121 and is used for installing a movable handle 124. The movable handle 124 is used to pull the insertion rod 121 to move, thereby increasing the convenience of use. At the same time, when the movable handle 124 is rotated to a vertical state with the base 123, the movable handle 124 is embedded in the circular groove 112, and the end of the movable handle 124 away from the base 123 is close to the inner bottom wall of the circular groove 112, which can limit the insertion rod 121 and ensure the stability of the insertion rod 121, that is, to ensure the stability of the connection between the pedal 130 and the ladder beam 110.

[0031] The working principle and use process of the utility model are as follows: when in use, the movable handle 124 is rotated outward to release the limit on the insertion rod 121, and the movable handle 124 is pulled to drive the insertion rod 121 to retract into the circular groove 112, and the support plate 132 is embedded in the groove 111 on the ladder beam 110, and the movable handle 124 is released. Under the action of the spring 122, the insertion rod 121 extends out of the circular groove 112 and is embedded in the slot 1321 on the support plate 132, and the support plate 132 is fixed to ensure the stability of the pedal 130. Then, the movable handle 124 is rotated to make it embedded in the circular groove 112, and the end portion is against the inner bottom wall of the circular groove 112, that is, the insertion rod 121 is limited to ensure the stability of the insertion rod 121, that is, the stability of the connection between the pedal 130 and the ladder beam 110 is ensured.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
