[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.
[0028] The present utility model provides a connection and fixing device for building stairs. It is connected to the stairs through a connecting mechanism. The connecting mechanism can rotate on the rotation hole through a rotating shaft, so that the connecting mechanism can be turned over, adjust the inclination angle of the connecting plate, make the connecting plate flush with the inclined stairs, and a gasket is arranged on the connecting plate to adjust the distance between the connecting plate and the stairs, so that the connecting plate and the stairs can be effectively connected. Please refer to Figures 1 - 3 , including: a fixing mechanism 100, a connecting mechanism 200 and an adjusting gasket 300.
[0029] The fixing mechanism 100 includes a substrate 110, a support block 120 and a rotation hole 130. The support block 120 is arranged on the side wall of the substrate 110, and the rotation hole 130 is arranged at the outer end of the support block 120;
[0030] Among them, the substrate 110 is installed on the building wall surface, and the support block 120 and the rotating hole 130 provide rotational support.
[0031] The connecting mechanism 200 is connected to the rotating hole 130. The connecting mechanism 200 includes a rotating shaft 210 and a connecting plate 220. The rotating shaft 210 is connected in the rotating hole 130, and the connecting plate 220 is arranged at the outer end of the rotating shaft 210.
[0032] Among them, the connecting plate 220 is used to connect the staircase frame. By driving the connecting plate 220 to rotate through the rotating shaft 210, the inclination angle of the connecting plate 220 is adjusted so that the connecting plate 220 can be parallel to the inclined staircase frame.
[0033] The adjusting gasket 300 is arranged on the connecting plate 220, and the number of the adjusting gaskets 300 can be changed according to the distance between the connecting plate 220 and the staircase frame, so as to change the thickness of the adjusting gasket 300.
[0034] Since the rotating shaft 210 will rotate freely and anti-rotation limit cannot be performed, uniformly distributed sliding grooves 140 are opened on the inner side of the outer end of the rotating hole 130, and sliding blocks 230 corresponding to the sliding grooves 140 are arranged on the outer wall of the rotating shaft 210.
[0035] Among them, the rotating shaft 210 drives the connecting plate 220 to rotate and change the inclination direction. After rotation, the sliding block 230 of the connecting plate 220 is correspondingly inserted into the sliding groove 140 for anti-rotation limit.
[0036] Since the rotating shaft 210 is smooth and easy to fall off from the rotating hole 130, uniformly distributed limiting holes 240 are arranged on the outer wall of one end of the rotating shaft 210 located in the rotating hole 130, and limiting bolts 150 connected to the limiting holes 240 are arranged on the side of the support block 120. After the rotating shaft 210 is connected, the limiting bolts 150 are locked on the limiting holes 240 to prevent the rotating shaft 210 from falling off from the rotating hole 130.
[0037] Since connection bolts are required, fixing holes 160 are opened on the substrate 110, connection holes 250 are arranged on the connecting plate 220, expansion bolts are installed on the fixing holes 160 for fixing to the building wall surface, and bolts are installed on the connection holes 250 for connecting the staircase frame.
[0038] To facilitate the insertion and extraction of the adjusting gasket 300, the adjusting gasket 300 adopts a stacked mountain-shaped gasket, and the adjusting gasket 300 can be inserted and extracted from the side for installation and disassembly.
[0039] Since rigid contact vibration will generate earthquake vibration and cause the bolt connection to loosen, the adjusting gasket 300 includes a metal gasket and a rubber gasket. The metal gasket and the rubber gasket are staggered and stacked, and the rubber gasket is used to absorb the impact force of vibration, playing a buffering effect and reducing the impact force transmitted to the bolt by stepping.
[0040] To improve the structural strength, a reinforcing rib 170 is provided at the connection position between the substrate 110 and the support block 120 to enhance the structural strength of the connection and prevent breakage.
[0041] During specific use, the substrate 110 is installed on the building wall surface. The rotating shaft 210 drives the connecting plate 220 to rotate and change the inclination direction. After rotation, the slider 230 of the connecting plate 220 is correspondingly inserted into the sliding groove 140 for anti-rotation limit. After the rotating shaft 210 is inserted, the limit bolt 150 is locked in the limit hole 240 to prevent the rotating shaft 210 from falling out of the rotating hole 130. The number of adjusting gaskets 300 can be changed according to the distance between the connecting plate 220 and the stair frame, thereby changing the thickness of the adjusting gaskets 300 to stably connect the connecting plate 220 and the stair frame, and being suitable for stable installation and use of stairs with different inclination angles.
[0042] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the disclosed embodiments of the present invention can be combined with each other in any way. The exhaustive description of these combinations is omitted in this specification only for the sake of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
