[0028] 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.
[0029] The purpose of this utility model is to provide a railing that solves the problems existing in the prior art, enabling the railing to adjust the spacing and arrangement angle of the vertical bars, with good appearance and construction quality, and low construction difficulty.
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] This utility model provides a railing, such as Figures 1-4 As shown, it includes: uprights 1 and crossbars 2. Each upright 1 is used for vertical installation, and at least one crossbar 2 is provided between two adjacent uprights 1. Each upright 1 is fixedly provided with a connecting rod 3 corresponding to each crossbar. Each connecting rod 3 is rotatably connected with a transition piece 4. The transition piece 4 can be rotated to adjust the relative angle between the transition piece 4 and the upright 1. The crossbar 2 is movably connected to the end of the transition piece 4 away from the upright. The crossbar 2 can move closer to or away from the upright 1 relative to the transition piece 4. The crossbar 2 is connected to the connecting rod 3 fixedly connected to the column 1 via the adapter 4. The adapter 4 and the connecting rod 3 form a rotatable connection around the vertical axis, which can adjust the relative angle between the crossbar 2 and the column 1. The crossbar 2 and the adapter 4 are movably connected, which can adapt to different spacings between two adjacent columns 1. Thus, the spacing and arrangement angle of the columns 1 can be adjusted according to the usage scenario, so that the railing can be installed in a straight line or a non-straight line. The connecting rod 3 is fixedly connected to the column 1 in the factory. There is no need to drill holes in the column 1 to install the crossbar 2. The column 1 has higher strength. On-site, only a mechanical connection is needed to connect the connecting rod 3 to the crossbar 2 through the adapter 4. Compared with the traditional welding method, the construction is simpler and the appearance and construction quality are better.
[0032] In another embodiment of this invention, the adapter 4 has a first mounting groove at the end near the column 1 and a second mounting groove at the end away from the column 1. The end of the connecting rod 3 away from the column 1 is rotatably connected to the first mounting groove, and the crossbar 2 is movably connected to the second mounting groove. By providing the first and second mounting grooves on the adapter 4, and connecting the second end of the connecting rod 3 and the crossbar 2 to the first and second mounting grooves respectively, the second end of the connecting rod 3 and the crossbar 2 can be limited, making the connection between the second end of the connecting rod 3 and the crossbar 2 and the first and second mounting grooves more secure.
[0033] In another embodiment of this example, as Figures 5-9 As shown, the railing also includes a connecting shaft, which includes a first bolt 8 and a second bolt 9. The adapter 4 has a first connecting hole and a second connecting hole respectively above and below the first mounting groove. Both the first connecting hole and the second connecting hole are connected to the first mounting groove. A third connecting hole 11 is provided on the end of the connecting rod 3 away from the column 1. The second bolt 9 passes through the first connecting hole and extends into the third connecting hole 11. The first bolt 8 passes through the second connecting hole and extends into the third connecting hole 11 and is threaded into the second bolt 9. Screwing the first bolt 8 into or out of the second bolt 9 can cause the top and bottom of the inner wall of the first mounting groove to press against or move away from the end of the connecting rod 3 away from the column 1, so as to lock or release the adapter 4 and the connecting rod 3. The first end of the adapter 4 is rotatably connected to the second end of the connecting rod 3 by means of a connecting shaft, which simplifies the construction. The top and bottom of the inner wall of the first mounting groove can deform. The axis of the connecting shaft is parallel to the vertical axis. When the top and bottom of the inner wall of the first mounting groove press against the end of the connecting rod 3 away from the column 1, the crossbar 2 is fixed relative to the column 1. When the top and bottom of the inner wall of the first mounting groove press against the end of the connecting rod 3 against the column 1, the adapter 4 can rotate relative to the connecting rod 3 around the axis of the connecting shaft, thereby adjusting the relative angle between the crossbar 2 and the column 1, so that the railing can be installed in a straight line or not in a straight line.
[0034] In another embodiment of this invention, the adapter 4 is U-shaped and includes two horizontal arms 5 and one vertical arm 6. The two horizontal arms 5 are distributed vertically, and the two ends of the vertical arm 6 are respectively connected to the ends of the two horizontal arms 5 away from the column 1. The space between the two horizontal arms 5 is the installation space. The end of the installation space near the column 1 forms a first installation groove. A through hole is provided on the vertical arm 6. The through hole and the end of the two installation spaces away from the column 1 together form a second installation groove. The crossbar 2 passes through the through hole and extends into the installation space. The outer wall of the crossbar 2 is threadedly connected to the inner wall of the through hole. Rotating the crossbar 2 can increase or decrease the length of the crossbar 2 extending into the second installation groove. Setting the adapter 4 as U-shaped, forming a first installation groove and a second installation groove between the two horizontal arms 5, has a simple structure, is easy to manufacture, and the space and length of the first installation groove formed by the U-shaped structure are large, the movable distance of the crossbar 2 is long, and the adjustable spacing range between two adjacent columns 1 is larger, which can adapt to more usage scenarios.
[0035] In another embodiment of this invention, the first connecting hole and the second connecting hole are respectively formed on the two horizontal arms 5 of the adapter 4. The second end of the connecting rod 3 extends into the first mounting groove between the two horizontal arms 5 of the U-shape, and the two horizontal arms 5 of the U-shape are rotatably connected to the second end of the connecting rod 3 through the connecting shaft, making construction simpler.
[0036] In another embodiment of this invention, the railing further includes a connecting ring 7 and a fixing bolt 10. The connecting ring 7 is connected to the vertical arm 6, and the horizontal bar 2 can pass through the connecting ring 7 and the through hole into the installation space. The connecting ring 7 has a fixing hole, and the fixing bolt 10 is threaded into the fixing hole and can abut against the horizontal bar 2 to lock the horizontal bar 2. The fixing bolt 10 can abut against and lock the horizontal bar 2, preventing the horizontal bar 2 from rotating after construction, making the connection between the horizontal bar 2 and the post 1 more secure.
[0037] In another embodiment of this invention, the inner diameter of the connecting ring 7 is equal to the inner diameter of the through hole, and the inner wall of the connecting ring 7 is threaded, with the crossbar 2 threadedly connected to the connecting ring 7. The thread within the connecting ring 7 corresponding to the crossbar 2 allows the crossbar 2 to be threadedly connected to both the connecting ring 7 and the through hole, increasing the length of the connection point, extending the movable distance of the crossbar 2, and widening the adjustable spacing range between adjacent columns 1. This allows for adaptation to more usage scenarios and provides a more secure connection.
[0038] In another embodiment of this invention, the crossbar 2 includes a first segment, a second segment, and a third segment connected in sequence. The diameters of the first and third segments are both smaller than that of the second segment. Both the first and third segments can be threadedly connected to the end of the adapter 4 furthest from the column. Threading the smaller-diameter first and third segments into the second mounting groove at the end of the adapter 4 furthest from the column 1 reduces the inner diameter of the second mounting groove, thereby reducing the volume of the adapter 4, saving materials, and facilitating transportation and storage.
[0039] In another embodiment of this invention, multiple fixing holes are distributed along the circumference of the connecting ring 7. The presence of multiple fixing holes along the circumference of the connecting ring 7 allows for the use of multiple fixing bolts 10 to fix the crossbar 2 along the circumference of the connecting ring 7, resulting in better fixing performance.
[0040] In another embodiment of this invention, a rubber pad is connected to the end of the fixing bolt 10 that abuts against the crossbar 2. The rubber pad increases the friction between the fixing bolt 10 and the crossbar 2, resulting in a better fixing effect, and the fixing bolt 10 will not wear down the threads on the crossbar 2, thus improving durability.
[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
