[0002] Sliding rail staircases are very convenient to use in daily life, allowing the stairs to be moved to the desired location along the rails. A search revealed patent CN213710157U, which discloses a portable sliding rail staircase. It includes a first fixed plate with second placement grooves on its surface. First fixed rods are located at both ends of the first fixed plate. Anti-slip pads are provided around the bottom of the first fixed plate. A first connecting shaft is located on one side of each of the first fixed rods, and a support rod is located at one end of the first connecting shaft. A fixing and limiting device is located inside the support rod. An electric sliding rail is located on the surface of the support rod, and an electric slider is located inside the electric sliding rail. The sliding rail rotates via pulleys located at the bottom of the placement plate, thereby moving the placement plate. This solves the problem of existing staircases being inconvenient to move. Furthermore, by retracting the support rod, it moves to the second placement grooves on the surface of the first fixed plate, thus folding the staircase away, solving the problem of inconvenient storage. Because the support rods of the staircase are tilted, the entire staircase cannot be vertically stowed. Furthermore, the pulleys installed make it easy for the main body of the staircase to move, making the use of the staircase unsafe. Utility Model Content

[0015] 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.

[0016] Example 1

[0017] Please see Figure 1-2 This utility model provides a sliding rail type staircase support structure, including a first step 1, a second step 2, a third step 3, and a sliding rail 8. The sliding rail 8 is fixedly installed on the wall. A slider 7 is fixedly installed on the left side of the first step 1. The slider 7 is slidably connected to the sliding rail 8 through the first step 1. The bottom of the third step 3 is in contact with the ground. Multiple second steps 2 are provided, all located between the first step 1 and the third step 3. Support columns 5 are symmetrically fixedly installed at the bottom of the first step 1 and the second step 2. Moving grooves 6 are symmetrically provided inside the top surface of the second step 2 and the third step 3. The support columns 5 are slidably connected to the inside of the moving grooves 6 through the first step 1 and the second step 2. The support columns 5 are all perpendicular to the first step 1, the second step 2, and the third step 3. A groove 4 is provided inside the top surface of the third step 3. When the main body of the staircase is stored, the first step 1, the second step 2, and the third step 3 can be moved to the left to store them.

[0018] Example 2

[0019] In this embodiment, as Figure 1-2As shown, a fixed rod 9 is fixedly installed on the bottom surface of the slider 7. A storage groove 10 is provided inside the fixed rod 9. A support rod 15 is hinged to the left side wall of the third step 3. A wheel 14 is symmetrically rotatably connected to the left end of the support rod 15. The wheel 14 is slidably connected inside the storage groove 10. The width of the support rod 15 matches the width of the storage groove 10. The distance between the fixed rod 9 and the left side wall of the third step 3 matches the total length of the support rod 15 and the wheel 14. The length of the support rod 15 is less than the length of the fixed rod 9. When the first step 1, the second step 2, and the third step 3 are opened, the support rod 15 moves downward and the wheel 14 moves inside the storage groove 14 until the support rod 15 is perpendicular to the fixed rod 9. Then the first step 1, the second step 2, and the third step 3 can be fully unfolded and supported.

[0020] Example 3

[0021] In this embodiment, as Figure 1-2 As shown, a wedge 13 is slidably connected inside the side wall of the storage groove 10. A limit rod 11 is fixedly connected to the left side wall of the wedge 13. A support block 16 is fixedly connected to the left end of the limit rod 11. A return spring 12 is fixedly installed between the support block 16 and the left side wall of the fixed rod 9. The return spring 12 is sleeved on the outside of the limit rod 11. The limit rod 11 is slidably connected inside the fixed rod 9. The wedge 13 is positioned above the support rod 15, which is perpendicular to the fixed rod 9. The bottom surface of the wedge 13 is in contact with the top surface of the wheel 14. When the support rod 15 moves downward, the wheel 14 presses down on the wedge 13, causing the wedge 13 to enter the interior of the fixed rod 9. When the support rod 15 is perpendicular to the fixed rod 9, the wedge 13 is reset by the action of the reciprocating motor 12. The bottom surface of the wedge 13 is in contact with the top surface of the wheel 14, thus limiting the support rod 15.

[0022] It should be noted that in this embodiment, when using a sliding rail staircase support structure, such as Figure 1-2As shown, when the first step 1, the second step 2, and the third step 3 are opened, the support rod 15 moves downward, and the wheel 14 moves inside the receiving groove 14 until the support rod 15 is perpendicular to the fixed rod 9. Then, the first step 1, the second step 2, and the third step 3 can be fully unfolded and supported. Simultaneously, the support rod 15 moves downward as the third step 3 moves. When the support rod 15 moves downward, the wheel 14 presses down on the wedge block 13, causing the wedge block 13 to enter the interior of the fixed rod 9. When the support rod 15 is perpendicular to the fixed rod 9, the wedge block 13 moves further... The motor 12 is reset, and the bottom surface of the wedge 13 is in contact with the top surface of the wheel 14, limiting the support rod 15. When storing the main body of the staircase, the limiting rod 11 is moved to the left, so that the wedge 13 enters the interior of the fixing rod 9. At the same time, the support rod 15 is moved upward, which can pull the third step 3, so that the wheel 14 moves above the wedge 13, and then pushes the third step 3, which can easily move the first step 1, the second step 2 and the third step 3, so that the main body of the staircase 1 can be stored easily. At the same time, the support rod 15 moves into the interior of the storage groove 10.
