DETAILED DESCRIPTION

[0030] The following is combined with Figures 1-8 This application is described in further detail.

[0031] The present application discloses a building staircase, which is used between the indoor and outdoor areas of the first floor of a building. Figure 1 、 Figure 2 and Figure 3 The building staircase includes steps 10, a storage box 20, and a guide support plate 30. There are a plurality of steps 10, which are arranged in sequence from top to bottom, and the height of the steps 10 gradually decreases from indoors to outdoors. The steps 10 are used to connect the indoor and outdoor areas of the first floor of the building. The steps 10 include a horizontal surface 11 facing upward and a vertical surface 12 facing outdoors.

[0032] The direction indicated by the arrow x is the length direction of the step 10, and the direction indicated by the arrow y is the width direction of the step 10. The storage box 20 extends along the length direction of the step 10. The length of the storage box 20 is slightly smaller than the length of the step 10, and the width of the storage box 20 is equal to the width of the step 10. A accommodating groove 111 is provided on the transverse surface 11 of the step 10. The storage box 20 is completely embedded in the accommodating groove 111 and is pre-buried on the step 10. The upper surface of the storage box 20 is flush with the transverse surface 11 of the step 10. The storage box 20 passes through the length of the step 10 to form a storage space. The side wall of the storage box 20 facing the outside is flush with the vertical surface 12 of the step 10. The guide support plate 30 can be slidably stored in the storage box 20 along the width direction of the step 10. When it is necessary to move wheeled objects such as battery vehicles between indoor and outdoor spaces on the first floor of the building, it is only necessary to pull the guide support plate 30 partially out of the storage box 20 and support it on the horizontal surface 11 of the next step 10, so that wheeled objects such as battery vehicles can be moved between indoor and outdoor spaces. It is convenient to use.

[0033] In order to facilitate the sliding of the guide support plate 30 in the storage box 20, a slide groove 21 extending along the width direction of the step 10 is opened on the two inner side walls of the storage box 20. Correspondingly, a pivot 31 is fixed on the two opposite side walls of the guide support plate 30. The two pivots 31 are coaxially arranged and arranged indoors near the first floor of the building. A rotatable roller 32 is sleeved on the pivot 31. The roller 32 is rollably connected to the slide groove 21 along the width direction of the step 10 to convert the sliding friction between the guide support plate 30 and the storage box 20 into rolling friction, thereby reducing the friction resistance between the guide support plate 30 and the storage box 20, making it convenient to push and pull the guide support plate 30.

[0034] Reference Figure 3 and Figure 4Considering that the width of the guide support plate 30 cannot be greater than the width of the step 10, that is, the guide support plate 30 cannot completely cover the next step 10, it is difficult for wheeled objects such as electric vehicles to move smoothly between indoors and outdoors. Therefore, the guide support plate 30 is rotatably connected to the extension plate 40 on the side facing the outdoors. Specifically, the guide support plate 30 is integrally provided with two first pivot blocks 33 on the side facing the first floor outdoors. The two first pivot blocks 33 are spaced apart along the length of the step 10. The extension plate 40 is integrally provided with a second pivot block 42 on the side facing the first floor indoors. The second pivot block 42 is located between the two first pivot blocks 33 and is rotatably connected between the two first pivot blocks 33 via a pivot shaft 43 extending along the length of the step 10. When the guide support plate 30 and the extension plate 40 are coplanar, the first limiting surface 331 and the second limiting surface 421 abut against each other, so that the guide support plate 30 and the extension plate 40 remain coplanar and do not rotate relative to each other to form an inclined upward-opening flap. The extension plate 40 supplements the width of the guide support plate 30 so that when the guide support plate 30 moves to the first position, the lower end of the extension plate 40 abuts against the corner of the next step 10, so as to facilitate the smooth and convenient movement of objects with wheels such as battery vehicles between indoors and outdoors (see Figure 7 ).

[0035] Reference Figure 3 and Figure 7 When using the guide support plate 30 and the extension plate 40, the extension plate 40 must first be flipped over to be coplanar with the guide support plate 30 before the extension plate 40 can be supported on the horizontal surface 11 of the next step 10, which is a cumbersome operation. Therefore, the building staircase also includes a slender elastic member 50. The elastic member 50 can be an elastic cord or a combination of a tension spring and an inelastic cord. In this embodiment, the elastic member 50 is described as an elastic cord. The end of the elastic member 50 facing the interior is fixed to the step 10, and the other end of the elastic member 50 passes through the guide support plate 30 and is fixed to the second limiting surface 421. Initially, the elastic cord is in a naturally extended state. When the guide support plate 30 slides out of the storage box 20, the elastic member 50, after being stretched, drives the second limiting surface 421 of the extension plate 40 to abut against the first limiting surface 331 of the guide support plate 30, thereby making the extension plate 40 coplanar with the guide support plate 30 and maintaining this state. This eliminates the need to flip the extension plate 40 when using the guide support plate 30 and the extension plate 40.

[0036] The extension plate 40 is supported on the horizontal surface 11 of the next step 10. When moving wheeled objects such as electric vehicles between indoor and outdoor spaces, the extension plate 40 and the guide support plate 30 are susceptible to sliding under pressure, posing a safety hazard. Therefore, locking grooves 22 are provided on the two opposing inner walls of the storage box 20. The upper ends of the locking grooves 22 communicate with the chute 21, and the lower ends of the locking grooves 22 are closer to the interior of the first floor of the building than the upper ends of the locking grooves 22. In this embodiment, the locking grooves 22 are described as quarter-circular arc grooves, allowing the roller 32 to slide from the chute 21 into the locking groove 22. When the guide support plate 30 moves to the first position, the elastic member 50 retains the roller 32 at the lower end of the locking groove 22, thereby locking the guide support plate 30. This prevents the guide support plate 30 from sliding under pressure, thereby improving the safety of the guide support plate 30 and the extension plate 40 during use. After the guide support plate 30 and the extension plate 40 are used, pull the guide support plate 30 outward until the roller 32 slides from the locking groove 22 to the sliding groove 21, release the guide support plate 30, and the guide support plate 30 can be stored in the storage box 20 under the action of the elastic member 50.

[0037] When heavy objects are moved on the guide support plate 30 and the extension plate 40, the guide support plate 30 is supported by the pivot 31, which can easily cause the pivot 31 to deform or even be damaged. Therefore, when the guide support plate 30 moves to the first position, it abuts the opening of the storage box 20. This multi-point support reduces the load on the pivot 31, making it less likely to deform or even be damaged.

[0038] Reference Figure 7 and Figure 8 When the guide support plate 30 and the extension plate 40 are not in use, the storage box 20 remains open, allowing debris to easily enter the storage box 20 and affect the smooth sliding of the guide support plate 30 within the storage box 20. Therefore, the axis of the pivot 31 is located on the lower surface of the guide support plate 30, so that when the guide support plate 30 is in a horizontal position, there is no gap between the top surface of the guide support plate 30 and the inner wall of the storage box 20.

[0039] The staircase also includes a locking structure 60 disposed on the vertical surface 12 of the step 10. When the locking structure 60 locks the extension plate 40, the guide support plate 30 is horizontally arranged, and the extension plate 40 is vertically arranged and abuts the vertical surface 12 of the step 10. Specifically, the locking structure 60 comprises a box body 62 and a protrusion 61. The box body 62 has a receiving cavity 621 with an opening facing the outside. The box body 62 is pre-embedded in the vertical surface 12 of the step 10, and the opening side of the box body 62 is flush with the vertical surface 12 of the step 10. The box body 62 has rotation holes 622 on the upper and lower side walls, and the two rotation holes 622 are coaxially arranged. The cross-section of the protrusion 61 is arranged in an arc shape, and the arc of the arc is a major arc. The upper and lower ends of the protrusion 61 are connected to the coaxial protrusions 611. The two protrusions 611 are rotatably connected to the two rotation holes 622 to rotate the protrusion 61 to the box body 62. When the protrusion 61 rotates to the second position, the protrusion 61 is completely received in the accommodating cavity 621. The extension plate 40 is provided with a through hole 41 extending therethrough. When the protrusion 61 rotates and slides out of the accommodating cavity 621, the protrusion 61 can be inserted into the through hole 41 to lock the extension plate 40 in the vertical position. At the same time, the guide support plate 30 and the extension plate 40 seal the opening of the storage box 20 facing the outside, making it difficult for debris to enter the storage box 20, and allowing the guide support plate 30 to slide smoothly in the storage box 20.

[0040] When the guide support plate 30 and the extension plate 40 are needed, it is only necessary to rotate the protrusion 61 to the second position, and then the extension plate 40 can be held by hand through the through hole 41 to pull out the guide support plate 30 until the guide support plate 30 moves to the first position, and the lower side of the extension plate 40 is placed on the horizontal surface 11 of the next step 10, so that objects with wheels such as electric vehicles can be moved between indoors and outdoors.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
