[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1: Please refer to Figures 1 to 6 :
[0028] This utility model proposes a personalized stair railing with adjustable height and angle, including: a post 1;
[0029] Three first connecting seats 2 are welded equidistantly on the outer side of the column 1. The column 1 supports the first connecting seats 2 and the second connecting seats 3. The first connecting seats 2 provide rotational support for the first horizontal bar 5 and the second horizontal bar 6. A second connecting seat 3 is also slidably installed on the outer side of the column 1. The second connecting seat 3 also provides rotational support for the first horizontal bar 5 and the second horizontal bar 6. A positioning bolt 4 is installed on the second connecting seat 3 to fix its height. A first horizontal bar 5 is rotatably installed on one side of both the first connecting seats 2 and the second connecting seat 3, and a second horizontal bar 6 is rotatably installed on the other side of both the first connecting seats 2 and the second connecting seat 3. The first horizontal bar 5 and the second horizontal bar 6 can cooperate to form a horizontal railing. A horizontal bar connecting sleeve 7 is provided at one end of the second horizontal bar 6. During installation, the first horizontal bar 5 can be extended and retracted in the horizontal bar connecting sleeve 7, so that the overall length of the railing can be changed, thereby ensuring that the column 1 can be installed on the plane of the staircase.
[0030] In this embodiment of the disclosure, such as Figure 5 As shown, the crossbar connecting sleeve 7 has a rectangular cavity with an opening on the left side, and the outer wall of the first crossbar 5 is in close contact with the inner wall of the rectangular cavity inside the crossbar connecting sleeve 7. Therefore, one end of the first crossbar 5 can slide stably in the crossbar connecting sleeve 7. During installation, the first crossbar 5 can be extended and retracted in the crossbar connecting sleeve 7, so the overall length of the railing can be changed, thereby ensuring that the post 1 can be installed on the plane of the staircase.
[0031] In this embodiment of the disclosure, such as Figures 1-4 and Figure 6 As shown, both the left and right sides of the first connecting seat 2 and the second connecting seat 3 are provided with a notch, and a set of round holes are provided in front of and behind the notch. The pivots at one end of the first horizontal bar 5 and the second horizontal bar 6 can rotate in the notches on both sides of the first connecting seat 2 and the second connecting seat 3. When installing this railing, one of the posts 1 can be fixed to the stairs with expansion screws first. Then, the other post 1 can be placed on the stairs according to the inclination angle of the stairs. During this process, the first horizontal bar 5 and the second horizontal bar 6 will automatically rotate and adjust due to the change in the height of the first connecting seat 2 and the second connecting seat 3, so that they can be installed on stairs with different inclination angles.
[0032] In this embodiment of the disclosure, such as Figures 1-5 As shown, a protrusion is provided on the front and rear sides of the right end of the first horizontal bar 5. A corresponding elongated slot is also provided on the front and rear outer walls of the horizontal bar connecting sleeve 7. When one end of the first horizontal bar 5 slides in the horizontal bar connecting sleeve 7, the protrusion on the front and rear sides of its right end will also slide left and right in the elongated slot on the front and rear outer walls of the horizontal bar connecting sleeve 7. Therefore, the stability of the first horizontal bar 5 during sliding adjustment can be guaranteed, and the first horizontal bar 5 can also be prevented from detaching from the horizontal bar connecting sleeve 7.
[0033] In this embodiment of the disclosure, such as Figures 1-4 and Figure 6 As shown, the middle part of the second connecting seat 3 is a cylindrical tube, and the inner diameter of the middle hole of the second connecting seat 3 is equal to the outer diameter of the column 1. When it is necessary to adjust the overall height of the railing, the second connecting seat 3 can be slid up and down on the outside of the column 1. At this time, the height of the first horizontal bar 5 and the second horizontal bar 6 between the adjacent second connecting seats 3 will also change, so the overall height of the railing can be adjusted. After adjustment, it can meet the needs of different people.
[0034] In this embodiment of the disclosure, such as Figures 1-4 and Figure 6 As shown, three through-holes are equidistantly arranged at the top of the column 1. The second connecting seat 3 is also provided with a set of through-holes. When adjusting the overall height of the railing, the second connecting seat 3 can be slid up and down on the outside of the column 1. At this time, the height of the first horizontal bar 5 and the second horizontal bar 6 between adjacent second connecting seats 3 will also change. Finally, the positioning bolt 4 is passed through the holes on the second connecting seat 3 and the column 1 and tightened with a nut.
[0035] Example 2, based on Example 1, such as Figures 1-6As shown, the horizontal bar connecting sleeve 7 has four inclined surfaces on both the left and right sides, and the overall length of the horizontal bar connecting sleeve 7 is 30cm. Therefore, the contact positions between the horizontal bar connecting sleeve 7 and the first horizontal bar 5 and the second horizontal bar 6 on the left and right sides will be smoother, making it more comfortable to touch the railing. The length of the horizontal bar connecting sleeve 7 also facilitates the overall extension and retraction adjustment of the first horizontal bar 5 and the second horizontal bar 6, thereby ensuring that the column 1 can be installed on the plane of the staircase.
[0036] The working principle of this embodiment is as follows: When installing this railing, one of the posts 1 can be fixed to the stairs first using expansion bolts. Then, according to the inclination angle of the stairs, the other post 1 can also be placed on the stairs. During this process, the first horizontal bar 5 and the second horizontal bar 6 will automatically rotate and adjust due to the change in the height of the first connecting seat 2 and the second connecting seat 3. Moreover, during installation, the first horizontal bar 5 can be extended and retracted in the horizontal bar connecting sleeve 7, thus changing the overall length of the railing. This ensures that the post 1 can be installed on the plane of the stairs. Then, the other post 1 can also be placed... The railing can be installed by fixing it with expansion screws in the above manner. When it is necessary to adjust the overall height of the railing, the positioning bolt 4 on the second connecting seat 3 can be removed first. Then, the second connecting seat 3 can be slid up and down on the outside of the column 1. At this time, the height of the first horizontal bar 5 and the second horizontal bar 6 between the adjacent second connecting seats 3 will also change, so the overall height of the railing can be adjusted. Finally, the positioning bolt 4 is passed through the round hole on the second connecting seat 3 and the column 1 and tightened with a nut. After adjustment, it can meet the needs of different people.
