[0045] See appendix Figure 1 - Appendix Figure 9A directional adjustable support frame includes a base 1, a base shaft 2, a connecting shaft 3, and a linkage arm 4. The base shaft 2 is mounted on the base 1. The connecting shaft 3 is located above the base 1 and parallel to the base shaft 2, and is used to mount a display device (not shown in the figure). The linkage arm 4 includes a first fixing component 41, a second fixing component 42, a swing rod 43, an elastic element 44, and two support rods 45. The first fixing component 41 and the second fixing component 42 are respectively mounted on the base shaft 2 and the connecting shaft 3. The first fixing component 41 is simultaneously hinged to the first end of the two support rods 45, and the second fixing component 42 is simultaneously hinged to the tail end of the two support rods 45 to form a parallelogram structure. The two ends of the swing rod 43 are rotatably connected to the first fixing component 41 and the second fixing component 42, respectively. The two ends of the elastic element 44 are respectively connected to the two support rods 45 and maintain the force balance of the linkage arm 4.

[0046] Specifically, before use, place the base 1 on a flat surface and install the display device onto the connecting shaft 3 so that the support arm can stably support the display device. When it is necessary to adjust the position of the display device, apply force to the linkage arm 4 to drive the swing arm 43 to rotate and simultaneously drive the two support rods 45 to expand or move closer to each other, thereby changing the height and horizontal position of the connecting shaft 3 to achieve the position adjustment of the display device.

[0047] During the swing of the linkage arm 4, the connecting shaft 3 moves stably and cannot rotate itself due to the parallelogram structure formed by the first fixing component 41, the second fixing component 42 and the two support rods 45. This allows the screen orientation to remain unchanged while adjusting the position of the display device. The elastic element 44 deforms adaptively with the movement of the two support rods 45 to maintain the force balance of the linkage arm 4, so that the linkage arm 4 can stop after swinging, ensuring that the display device is stably suspended in the current position.

[0048] In summary, this utility model connects the base shaft 2, which is installed on the base 1, and the connecting shaft 3, which is used to install the display device, through the linkage arm 4, so that the base 1 can provide support for the display device through the linkage arm 4. The linkage arm 4 is designed with a swing rod 43 and an elastic element 44 to form a parallelogram structure composed of a first fixing component 41, a second fixing component 42, and two support rods 45. It is not only easy to operate and has high structural stability, but also can keep the screen orientation unchanged during the adjustment of the display device position, thus improving the user experience.

[0049] It should be noted that the display device can be an LCD TV, computer monitor, tablet computer, etc., and the connecting shaft 3 can also be used to install other electronic products to replace the display device. This utility model does not limit the installation object; while the base shaft 2 can be detachably installed on the base 1 by bolts or clips. Since there are various installation methods and most of them are conventional technologies, this utility model will not list them all.

[0050] See appendix Figure 3 Appendix Figure 4 Appendix Figure 10 and attached Figure 11 Regarding the structural composition of the first fixing component 41 and the various installation methods of the base shaft 2 and the first fixing component 41, this utility model does not impose any restrictions on these. For ease of understanding, in this embodiment, the base shaft 2 is provided with a first slot 20, and the first fixing component 41 includes a first fastening wheel 411, a first pin 412, a first bushing 413, and a first nut 414. The first bushing 413 is inserted into the first slot 20, and the first pin 412 is sequentially inserted into the first fastening wheel 411, the rocker arm 43, the first bushing 413, and the first nut 414, with the first nut 414 abutting against the first bushing 413. A screw 21 is also installed on the base shaft 2, penetrating into the first slot 20 and abutting against the first bushing 413, to fix the first bushing 413 to the base shaft 2. The rocker arm 43 is rotatably connected to the first pin 412, and the first fastening wheel 411 is simultaneously hinged to the ends of the two support rods 45.

[0051] Specifically, during assembly, the first pin 412 is sequentially inserted into the first fastening wheel 411, the rocker arm 43, and the first bushing 413, and the first pin 412 is threadedly connected to the first bushing 413 by the first nut 414. Then, the first bushing 413 is inserted into the first slot 20, and the first bushing 413 is tightened by the screw 21 set on the base shaft 2. This design facilitates the disassembly and assembly of the first fixing component 41 with the base shaft 2 and the rocker arm 43.

[0052] In use, the first fastening wheel 411 is fixed under the constraint of the base shaft 2 and the first bushing 413, and applies force to the linkage arm 4, driving the swing arm 43 to rotate around the first pin 412 and simultaneously driving the two support rods 45 to expand or move closer to each other, thereby changing the height and horizontal position of the connecting shaft 3 to realize the position adjustment of the display device.

[0053] See appendix Figure 10 - Appendix Figure 14 The first fixing component 41 also includes a first friction plate 415, which is fitted with a first pin 412 and abuts against the swing arm 43 and the first fastening wheel 411. The design of the first friction plate 415 can continuously provide rotational damping to the swing arm 43, thereby enriching the operating feel of the linkage arm 4 and improving the overall support capacity of the linkage arm 4, ensuring that the display device can be hovered more stably.

[0054] Furthermore, there are two first friction plates 415. The two first friction plates 415 are located on opposite sides of the swing arm 43 and simultaneously abut against the swing arm 43. The two first friction plates 415 also abut against the first fastening wheel 411 and the first bushing 413 respectively, so as to provide damping to both sides of the swing arm 43 simultaneously, thereby further improving the support capacity of the linkage arm 4 and making the overall structure more stable in use.

[0055] See appendix Figure 3 Appendix Figure 5 Appendix Figure 10 and attached Figure 12 The connecting shaft 3 has a second slot 30 inside. The second fixing component 42 includes a second fastening wheel 421, a second pin 422, a second bushing 423, and a second nut 424. The second bushing 423 is inserted into the second slot 30. The second pin 422 is sequentially inserted into the second fastening wheel 421, the rocker arm 43, the second bushing 423, and the second nut 424, with the second nut 424 abutting against the second bushing 423. The rocker arm 43 is rotatably connected to the second pin 422, and the second fastening wheel 421 is synchronously hinged to the tail ends of the two support rods 45.

[0056] Specifically, during assembly, the second pin 422 is sequentially inserted into the second fastening wheel 421, the rocker arm 43, and the second bushing 423. The second pin 422 is then threadedly connected to the second bushing 423 via the second nut 424, and the second bushing 423 is then inserted into the second slot 30. This design facilitates the disassembly and assembly of the second fixing component 42 with the connecting shaft 3 and the rocker arm 43.

[0057] In use, the second fastening wheel 421 is fixed under the constraint of the connecting shaft 3 and the second bushing 423, and applies force to the linkage arm 4, driving the swing arm 43 to rotate around the second pin 422 and simultaneously driving the two support rods 45 to expand or move closer to each other, thereby changing the height and horizontal position of the connecting shaft 3 to achieve the position adjustment of the display device; and since the connecting shaft 3 is restricted by the parallelogram structure composed of the first fastening wheel 411, the second fastening wheel 421 and the two support rods 45 and cannot rotate, the screen orientation of the display device can be kept unchanged.

[0058] See appendix Figure 10 - Appendix Figure 14 The second fixing component 42 also includes a second friction plate 425. The second friction plate 425 is fitted with a second pin 422 and abuts against the swing arm 43 and the second fastening wheel 421. The design of the second friction plate 425 can continuously provide rotational damping to the swing arm 43, thereby enriching the operating feel of the linkage arm 4 and improving the overall support capacity of the linkage arm 4, ensuring that the display device can be hovered more stably.

[0059] See appendix Figure 8 - Appendix Figure 14 In order to allow the screen orientation to be adjusted individually, the second fixing component 42 in this invention also includes a spring piece 426, a second bushing 423 rotatably connected to a second pin 422, and a spring piece 426 sleeved on the second pin 422 and abutting against the second bushing 423 and the second nut 424 to provide rotational damping to the connecting shaft 3.

[0060] Specifically, during the process of adjusting the position of the display device, the second bushing 423 remains fixed under the pressure of the spring 426, so the connecting shaft 3 cannot rotate normally, thus maintaining the screen orientation unchanged.

[0061] Once the screen display device position is adjusted, if the user needs to adjust the screen orientation separately, the connecting shaft 3 is rotated to drive the second bushing 423 to overcome the damping provided by the spring piece 426, so that the connecting shaft 3 can rotate normally to adjust the screen orientation; after the screen orientation meets the requirements, the connecting shaft 3 is released, so that the screen can maintain the current orientation and hover.

[0062] See appendix Figure 8 - Appendix Figure 14 To prevent the display device from causing the connecting shaft 3 to rotate around the second pin 422, the damping applied by the spring 426 and the second bushing 423 should be greater than the weight of the display device itself. This puts a heavy burden on the spring 426. To reduce the burden on the spring 426, in this utility model, the second fixing component 42 also includes a positioning block 427 and a coil spring 428. The positioning block 427 is fixedly sleeved on the second pin 422, and the coil spring 428 is sleeved on the second pin 422. The two ends of the coil spring 428 are respectively connected to the second bushing 423 and the positioning block 427.

[0063] Specifically, under normal circumstances, the coil spring 428 is in its initial state and continuously provides preload to the connecting shaft 3 to counteract the weight of the display device. When the user rotates the connecting shaft 3, the coil spring 428 undergoes adaptive deformation and has a more sufficient elastic tendency. As long as the elastic tendency remains within a certain range, it can still normally counteract the weight of the display device and the damping provided by the spring 426 to ensure force balance and prevent the connecting shaft 3 from resetting. Since the coil spring 428 counteracts the weight of the display device, it can effectively reduce the burden on the spring 426 during actual use and provide rotational and stopping stability of the connecting shaft 3, further improving the user experience.

[0064] See appendix Figure 8 - Appendix Figure 12 Multiple elastic elements 44 are arranged in an array along the length of the swing arm 43. Each elastic element 44 is surrounded by two support rods 45 of the swing arm 43. The first end of each elastic element 44 is connected to one of the support rods 45, and the second end of each elastic element 44 is connected to the other support rod 45. The design of multiple elastic elements 44 can further improve the load-bearing capacity of the linkage arm 4, ensuring that when a heavy display device is installed on the connecting shaft 3, the force balance can still be maintained, and ensuring that the display device can be stably stopped after the position is adjusted.

[0065] It should be noted that the elastic element 44 can be a spring, rubber strip, elastic plastic rope, etc. Due to the variety of types, this utility model does not limit it. For ease of understanding, this utility model takes a spring as an example.

[0066] See appendix Figure 8 - Appendix Figure 12 The two support rods 45 are provided with mutually cooperating limiting ports 451 and limiting blocks 452. The limiting blocks 452 are located at the limiting ports 451, and the limiting blocks 452 can abut or disengage from the inner wall of the limiting ports 451 as the two support rods 45 swing against each other. The cooperation between the limiting blocks 452 and the limiting ports 451 can limit the rotation range of the swing rod 43 and prevent the linkage arm 4 from swinging excessively as a whole.

[0067] See appendix Figure 3 - Appendix Figure 8 The linkage arm 4 is provided in two sets and is respectively set at the left and right ends of the base shaft 2, and the two sets of linkage arms 4 enclose the connecting shaft 3. The design of the two sets of linkage arms 4 enables the two ends of the connecting shaft 3 to be supported synchronously, thereby improving the overall load-bearing capacity and further ensuring the structural stability.

[0068] See appendix Figure 1 - Appendix Figure 7 The present invention also includes a housing 5, which encloses the two sets of linkage arms 4. The housing 5 has a first notch 51 and a second notch 52 at its upper and lower ends, respectively. The base shaft 2 is placed in the first notch 51 and can move relative to the housing 5. The connecting shaft 3 is placed in the second notch 52 and can move relative to the housing 5. The design of the housing 5 can prevent the linkage arms 4 from being exposed, improve the overall aesthetics, and at the same time restrict the second fixing component 42 of the linkage arm 4 to the connecting shaft 3, prevent the connecting shaft 3 from detaching from the linkage arm 4, and improve the installation stability.

[0069] Furthermore, the display device is located on the front side of the housing 5, and the first notch 51 only opens to the rear side of the housing 5 to limit the angle of movement between the base shaft 2 and the first notch 51, so as to prevent the linkage arm 4 from swinging forward; the second notch 52 opens to the front and rear sides of the housing 5, so that the connecting shaft 3 and the second notch 52 have a more sufficient angle of movement, thereby increasing the adjustable range of the position of the display device.

[0070] See appendix Figure 1 - Appendix Figure 7 The present invention also includes a power supply unit (not shown in the figure) and a storage unit (not shown in the figure). The power supply unit and the storage unit are installed inside the housing 5 and are both electrically connected to the display device. The housing 5 is also provided with a charging port 53 that is electrically connected to the power supply unit.

[0071] Specifically, the power supply unit can consist of a circuit board and a battery that are electrically connected to each other. The circuit board can be connected to the display device via a data cable to provide power, while the charging port 53 can be connected to an external power cord to charge the battery. The storage unit can be a hard drive, which can also be connected to the display device via a data cable to expand memory.

[0072] The above design can further enrich the function of this support frame. However, since the design of the power supply unit, storage unit and charging port 53 are all conventional technologies, their specific circuit structures will not be described in detail in this utility model.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
