Technical Field

[0001] The utility model relates to the technical field of mounting brackets, in particular to a display screen mounting bracket for subway communications. Background Art

[0002] The display screen mounting bracket for subway communication is a device used in subway communication systems. Its main function is to fix the display screen to ensure that the display screen can display information stably during subway operation.

[0003] The existing installation brackets of the subway communication display screens are all fixed, and the angle of the display screen cannot be adjusted at will. Moreover, the structure is complex, and a large space is occupied. Moreover, holes need to be punched in the wall, and the wall needs to be damaged.

[0004] Although some existing installation brackets for subway communication display screens do not require drilling holes in wall columns, they still require workers to install them at high places on wall columns using tools such as ladders during installation. This is not only inconvenient for installation, but also inconvenient for daily maintenance. Utility Model Content

[0022] See also Figure 1-4 A display screen installation bracket for subway communication includes a fixed bracket 20; a slide groove 21 is opened on one side of the fixed bracket 20, and a positioning threaded rod 22 is movably connected inside the fixed bracket 20, and a linkage column 18 is provided on one side of the fixed bracket 20, and one end of the linkage column 18 is slidably connected to the inside of the slide groove 21, and one end of the linkage column 18 is threadedly connected by the positioning threaded rod 22, and a sleeve column 17 is provided at one end of the linkage column 18 away from the fixed bracket 20, and a connecting bracket 10 is provided at one end of the sleeve column 17 away from the linkage column 18, and one end of the sleeve column 17 is slidably connected to one side of the connecting bracket 10, and a display 19 is movably connected to one side of the connecting bracket 10, and a telescopic bracket 13 is welded to the lower part of the connecting bracket 10, and a connecting block 29 is welded to one side end of the fixed bracket 20, and a first connector 23 and a second connector 28 are movably connected to the lower part of the connecting block 29, and a fixed column 24 is provided on one side of the fixed bracket 20, and a threaded column 27 is threadedly connected to the internal thread of the fixed column 24, and one end of the threaded column 27 is plugged and connected to the connecting bracket 10.

[0023] Specifically, a limiting column 12 is inserted on the upper side of the connecting bracket 10 , and the limiting column 12 passes through one end of the threaded column 27 to fix the threaded column 27 and the connecting bracket 10 .

[0024] Through the above technical solution, when the limiting column 12 is pulled out, one end of the threaded column 27 will no longer be restricted. At this time, the threaded column 27 can be separated from the fixed column 24, so that the entire object can be wrapped around the periphery of the wall column. After wrapping around and resetting the threaded column 27, the first connector 23 and the second connector 28 can be rotated to position and clamp the entire object around the periphery of the wall column.

[0025] Specifically, a gear ring 25 is welded to the periphery of the fixed column 24 by means of a socket connection, one side of the gear ring 25 is meshedly connected to a gear member 26, one side of the gear member 26 is meshedly connected to a second connector 28, and the gear member 26 is movably connected to the inside of a connector block 29 to drive the fixed column 24 to rotate.

[0026] Through the above technical solution, the bottom of the first connector 23 and the second connector 28 are both provided with plug-in grooves for connecting external handwheel tools; when the second connector 28 rotates to allow the fixed column 24 to rotate, the threaded column 27 will continuously enter the interior of the fixed column 24, so that the fixed bracket 20 is close to the connecting bracket 10, and then the wall column is clamped and fixed.

[0027] Specifically, one end of the positioning threaded rod 22 is engaged with the first connector 23 to drive the positioning threaded rod 22 to rotate.

[0028] Through the above technical solution, one end of the positioning threaded rod 22 has a gear; the first connector 23 and the second connector 28 have gear plates located inside the connecting block 29, which can mesh with the positioning threaded rod 22 and allow the second connector 28 to mesh with the gear member 26.

[0029] Specifically, the linkage column 18 is movably connected to the interior of the sleeve column 17 to facilitate the rotation and extension of the linkage column 18 .

[0030] Through the above technical solution, a groove is also opened on one side of the connecting bracket 10, and a slider is arranged in the groove. The slider is fixedly connected to one end of the sleeve column 17, so that the sleeve column 17 can be slidably connected to the connecting bracket 10, which is mainly used to cooperate with the sliding of the linkage column 18. When the positioning threaded rod 22 rotates, the sleeve column 17 and the linkage column 18 will be close to the fixed column 24 to clamp the wall column.

[0031] Specifically, a support frame 14 is inserted below the telescopic bracket 13 . Both the telescopic bracket 13 and the support frame 14 are provided with evenly distributed holes 15 . Bolts 16 are connected inside the holes 15 to fix the relative positions of the support frame 14 and the telescopic bracket 13 .

[0032] Through the above technical solution, the plug-in part of the support frame 14 has a limit block, so that it can slide up and down within a limited range, and the bolt member 16 cooperates with the hole 15 to position the support frame 14 after the position of the support frame 14 is manually adjusted.

[0033] Specifically, one end of the support frame 14 away from the telescopic support 13 is located below the display 19 for supporting the display 19 . One side of the display 19 is movably connected to a tilting block 11 , and the tilting block 11 is welded to one side of the connecting support 10 .

[0034] Through the above technical solution, the display 19 is a display screen for subway communications, and its back is movably connected to the tilting block 11 through an insertion rod, and can then rotate around the movable connection as the center, so that its angle can be adjusted when the support frame 14 is extended and retracted for people to watch.

[0035] When in use, by setting the connecting bracket 10 and the fixing bracket 20 and their respective objects, before installing the display 19, the bolt 16 can be pulled out by a tool, and the top end of the support frame 14 can be inserted into a part of the inside of the telescopic bracket 13 or pulled out, so that the display 19 can rotate around the movable connection with the tilting block 11, and then adjust its angle. When installation is required, the limit column 12 can be pulled out, so that one end of the threaded column 27 is no longer restricted by the connecting bracket 10. At this time, after the entire installation bracket is wrapped around the outside of the wall column, the threaded column 27 is re-inserted into the connecting bracket 10 and the limit column 12 is inserted to fix one end of the threaded column 27. At this time, after the entire object is moved to the target height, the linkage column 18 and the sleeve column 17 are moved to the fixed position by rotating the positioning threaded rod 22. The column 24 is close, and the fixing bracket 20 is moved closer to the connecting bracket 10 by rotating the fixing column 24, thereby clamping and positioning the periphery of the wall column. Finally, the mounting bracket can be installed without drilling holes in the wall, and the angle of the display screen can be adjusted. Through the set fixing bracket 20 and its object, when installing, the bottom of the first connector 23 and the second connector 28 can be connected through the external handwheel rod and the push rod can be used at the other end of the fixing bracket 20 to push the entire object to the target height. At this time, selecting the first connector 23 will allow the positioning threaded rod 22 to rotate, and rotating the second connector 28 will cause the gear ring 25 to rotate with the fixing column 24 through the transmission of the gear part 26. Finally, the entire mounting bracket can be installed and disassembled quickly and conveniently for repairing the display 19.
