[0022] 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.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an adjustable antenna support structure for digital television transmission, including a support body 1, a storage groove 2 inside the support body 1, a guide block 3 fixedly connected to the inner side wall of the storage groove 2, a support plate 4 fixedly connected to the outer wall of the support body 1, a threaded groove 5 inside the support plate 4, a rotating rod 6 movably connected inside the support plate 4, a knob 7 fixedly connected to one end of the rotating rod 6, a transmission gear 8 fixedly connected to the outer wall of the rotating rod 6, a rack 9 movably connected to the outer wall of the transmission gear 8, a limit plate 10 fixedly connected to the top of the rack 9, a lifting column 11 movably connected inside the support body 1, a limit groove 12 inside the lifting column 11, and a guide groove 13 inside the lifting column 11.

[0024] The outer wall of the rotating rod 6 is threaded, and the rotating rod 6 is threaded to the support plate 4 through the threaded groove 5, so that the rotating rod 6 can be inserted into the threaded groove 5 for limiting after rotation.

[0025] The transmission gear 8 forms a rotating structure with the support plate 4 via the rotating rod 6. The transmission gear 8 meshes with the rack 9, which can make the transmission gear 8 rotate and drive the rack 9 to move.

[0026] The limiting plate 10 and the bracket body 1 form a sliding structure. The limiting plate 10 is engaged with the lifting column 11 through the limiting groove 12. The limiting groove 12 is evenly distributed on one side of the lifting column 11. The guide block 3 is located in the guide groove 13, which allows the limiting plate 10 to be inserted into the corresponding limiting groove 12 for limiting.

[0027] The lifting column 11 has a docking slot 14 inside, and a threaded hole 15 is formed on the inner top wall of the docking slot 14. An internal hexagon bolt 16 is movably connected inside the threaded hole 15. A docking block 17 is installed inside the lifting column 11, and a limit hole 18 is formed inside the docking block 17. An antenna body 19 is fixedly connected to the outer wall of the docking block 17. The main function of the antenna body is to receive digital television signals. In this embodiment, the antenna body is only for illustrative purposes; the antenna body can also have other shapes, which are not limited here.

[0028] The lifting column 11 is connected to the docking block 17 by the docking slot 14. The docking block 17 is adapted to the docking slot 14, so that the docking block 17 can be inserted into the docking slot 14 for docking.

[0029] The lifting column 11 is threadedly connected to the internal hex bolt 16 through the threaded hole 15. The internal hex bolt 16 is engaged with the mating block 17 through the limiting hole 18, so that the end of the internal hex bolt 16 can be inserted into the limiting hole 18 for limiting.

[0030] Working principle:

[0031] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 By rotating knob 7, the transmission gear 8 fixedly connected to the outer wall of the rotating rod 6 can be rotated. Since the transmission gear 8 is meshed with the rack 9, it drives the rack 9 to move. The movement of the rack 9 will cause the limiting plate 10 to slide along the bracket body 1 and move the limiting plate 10 out of the limiting groove 12 at the current position. After the limiting groove 12 moves out of the limiting plate 10, the lifting column 11 is pulled, causing the lifting column 11 to slide along the storage groove 2 opened inside the bracket body 1. The sliding of the lifting column 11 causes the guide block 3 to slide along the guide groove 13. When the lifting is adjusted to the required height, the knob 7 is rotated in the opposite direction, causing the transmission gear 8 fixedly connected to the outer wall of the rotating rod 6 to reverse. The transmission gear 8 drives the end of the rotating rod 6 to insert into the threaded groove 5 for limiting. Since the end of the rotating rod 6 is inserted into the threaded groove 5, the limiting plate 10 is reset and inserted into the limiting groove 12 at the corresponding position, thus achieving the limiting of the lifting column 11.

[0032] according to Figure 1 and Figure 5 By moving the antenna body 19, the docking block 17 is inserted into the docking slot 14. Then, the internal hex bolt 16 is moved to dock with the top of the threaded hole 15 and rotated. Since the internal hex bolt 16 is threadedly connected to the lifting column 11 through the threaded hole 15, the internal hex bolt 16 can be rotated and moved along the threaded hole 15, so that the bottom end of the internal hex bolt 16 is inserted into the limiting hole 18 for limiting, so that the lifting column 11 and the antenna body 19 are stably assembled.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
