Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the Figures 1-4 accompanying drawings.

[0033] An embodiment of the present application discloses a suspended staircase structure for indoor use. Referring to Figure 1 and Figure 2 , the suspended staircase structure for indoor use includes a support plate 1 embedded on one side of a wall and a pedal 2 sleeved on the support plate 1; the support plate 1 is horizontally arranged, and one end of the support plate 1 far from the wall extends outside the wall; there are a plurality of support plates 1, and the plurality of support plates 1 are arranged in a stepped manner on one side of the wall. A fixing component is arranged on each pedal 2, and the fixed end of the fixing component is connected to the corresponding support plate 1 to fix the pedal 2 on the support plate 1; a covering component is arranged on the pedal 2, and the covering component is used to cover the adjusting end of the fixing component so that the adjusting end of the fixing component cannot be operated.

[0034] Referring to Figure 1 and Figure 2 , in order to enable the support plate 1 to be more firmly fixed on the wall, a reinforcing plate 11 is fixedly connected to one end of the support plate 1 embedded in the wall, and the length direction of the reinforcing plate 11 is perpendicular to the length direction of the support plate 1; the arrangement of the reinforcing plate 11 increases the area of the support plate 1 embedded in the wall, so that the support plate 1 can be more firmly fixed on the wall. The pedal 2 is a hollow sleeve body with one end open, and one end of the support plate 1 far from the reinforcing plate 11 extends into the pedal 2 along the opening of the pedal 2.

[0035] Referring to Figure 1 and Figure 2 , at the same time, in order to enable the pedal 2 to be more smoothly sleeved on the support plate 1, a long sliding strip 12 is fixedly connected to the side surface of the support plate 1, a sliding groove corresponding to the position of the long sliding strip 12 is opened on the inner side wall of the pedal 2, the length direction of the sliding groove is consistent with the length direction of the pedal 2, and the long sliding strip 12 is slidably connected with the sliding groove. There are two long sliding strips 12 on the same support plate 1, the two long sliding strips 12 are symmetrically arranged on both sides of the support plate 1, and the number of sliding grooves on the pedal 2 is the same as and corresponds to the number of long sliding strips 12 on the support plate 1 one by one.

[0036] Referring to Figure 1 andFigure 2 One end of the support plate 1 away from the reinforcement plate 11 is provided with a receiving groove 13. The fixing assembly includes a mounting rod 3 installed in the receiving groove 13, an elastic piece 31 arranged on the circumferential side of the mounting rod 3, a fixing shaft 32 arranged on the elastic piece 31, and an adjusting member arranged on the pedal 2. The cross-section of the elastic piece 31 is V-shaped and its opening faces the adjusting member. The inner side of the elastic piece 31 is fixedly connected to the circumferential side of the mounting rod 3, and the mounting rod 3 is located at the end of the elastic piece 31 away from the adjusting member. The fixing shaft 32 is fixed on the outer side of the elastic piece 31 and is located at the opening of the elastic piece 31. A fixing groove 22 corresponding to the position of the fixing shaft 32 is formed in the inner wall of the pedal 2, and one end of the fixing shaft 32 away from the elastic piece 31 penetrates through the support plate 1 and extends into the fixing groove 22.

[0037] Thus, when the adjusting member abuts against the elastic piece 31, the opening of the elastic piece 31 expands outwards. The expanded elastic piece 31 drives the fixing shaft 32 to penetrate through the support plate 1 and extend into the fixing groove 22, thereby fixing the pedal 2 on the support plate 1. At the same time, in order to make the pedal 2 be fixed on the support plate 1 more stably, two fixing shafts 32 are arranged on the elastic piece 31. The two fixing shafts 32 are symmetrically arranged on the elastic piece 31, and the number of the fixing grooves 22 is the same as that of the fixing shafts 32 and they correspond to each other one by one.

[0038] Refer to Figure 2 and Figure 3 One end of the pedal 2 away from the support plate 1 is provided with a mounting groove 21. The adjusting member includes a screw rod 33 threadedly connected to the pedal 2, a turntable 34 fixedly connected to the end of the screw rod 33 and located in the mounting groove 21, and an abutting block 35 fixedly connected to the end of the screw rod 33 away from the turntable 34. The cross-section of the abutting block 35 is frustum-shaped, and the end with a smaller cross-sectional area of the abutting block 35 faces the elastic piece 31. The abutting block 35 is located in the receiving groove 13 and abuts against the elastic piece 31.

[0039] Thus, the pedal 2 is sleeved on the support plate 1. At this time, the abutting block 35 is located in the receiving groove 13. By rotating the screw rod 33 through the turntable 34, since the screw rod 33 is threadedly connected to the pedal 2, the screw rod 33 drives the abutting block 35 to abut against the elastic piece 31, so that the opening of the elastic piece 31 expands outwards. The expanded elastic piece 31 drives the fixing shaft 32 to penetrate through the support plate 1 and extend into the fixing groove 22, thereby fixing the pedal 2 on the support plate 1.

[0040] At the same time, an internal hexagonal groove 341 is formed at one end of the turntable 34 away from the screw rod 33, so as to facilitate rotating the turntable 34 located in the mounting groove 21 by an internal hexagonal wrench.

[0041] Refer to Figure 2 and Figure 4, the covering assembly includes a cover plate 36 hinged at the notch of the installation groove 21 and a locking member provided on the cover plate 36; a locking groove 211 corresponding to the locking end of the locking member is formed on the installation groove 21; when the cover plate 36 is covered at the notch of the installation groove 21, the locking end of the locking member is inserted and matched with the locking groove 211, so as to lock the cover plate 36 at the notch of the installation groove 21.

[0042] Referring to Figure 2 and Figure 4 , a placement groove 361 is formed at one end of the cover plate 36 close to the locking groove 211. The locking member includes a locking block 37 slidably connected in the placement groove 361 and inserted and matched with the locking groove 211, and a spring 38 fixed between the locking block 37 and the placement groove 361; a guide rod 39 is fixedly connected in the placement groove 361, the spring 38 is sleeved on the periphery of the guide rod 39, and a guide groove 371 slidably connected with the guide rod 39 is formed at one end of the locking block 37 away from the locking groove 211.

[0043] In order to facilitate the operation of the locking block 37, a long slot 362 corresponding to the position of the locking block 37 is formed on the side of the cover plate 36 away from the turntable 34. A pulling block 372 is fixedly connected to the side of the locking block 37 away from the turntable 34. One end of the pulling block 372 away from the locking block 37 passes through the long slot 362 and extends outside the cover plate 36, and the pulling block 372 is slidably connected with the long slot 362.

[0044] Referring to Figure 2 and Figure 4 , at the same time, when the cover plate 36 is covered at the notch of the installation groove 21, in order to enable the locking block 37 to be automatically inserted into the locking groove 211, a slope is provided at one end of the locking block 37 away from the guide rod 39. Thus, when the cover plate 36 is covered at the notch of the installation groove 21, the slope of the locking block 37 abuts against the pedal 2. At this time, the guide rod 39 and the guide groove 371 are slidably connected, and the spring 38 is compressed, so that the locking block 37 contracts into the placement groove 361. When the locking block 37 corresponds to the position of the locking groove 211, under the reset action of the spring 38, the locking block 37 is inserted and matched with the locking groove 211, so as to lock the cover plate 36 at the notch of the installation groove 21.

[0045] The implementation principle of a suspended staircase structure for indoor use in an embodiment of this application is as follows: The pedal 2 is sleeved on the support plate 1. When the turntable 34 is rotated, since the screw 33 is threadedly connected to the pedal 2, the screw 33 drives the abutting block 35 to abut against the elastic piece 31, so that the opening of the elastic piece 31 expands outward. The outwardly expanded elastic piece 31 drives the fixed shaft 32 to penetrate through the support plate 1 and extend into the fixed groove 22, thereby fixing the pedal 2 on the support plate 1. Then, the cover plate 36 is closed on the notch of the installation groove 21, and the inclined surface of the locking block 37 abuts against the pedal 2. At this time, the guide rod 39 and the guide groove 371 are slidably connected, and the spring 38 is compressed, so that the locking block 37 retracts into the placement groove 361. When the position of the locking block 37 corresponds to the locking groove 211, under the reset action of the spring 38, the locking block 37 is inserted and matched with the locking groove 211, thereby locking the cover plate 36 at the notch of the installation groove 21.

[0046] The above are all the preferred embodiments of this application.
