[0029] In order to make the person skilled in the art better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0030] As Figure 1 and Figure 2To achieve the above object, the utility model provides an adjustable support, which comprises a base 1, a rotating shaft 2 arranged on the base 1 and a telescopic rod set 4 arranged on the base 1.

[0031] The rotating shaft 2 is arranged on the left side of the base 1, and the rotating shaft 2 is rotatably connected to the fixed plate 3; the fixed plate 3 is used for connecting the display screen 7; specifically, the rotating shaft 2 is arranged on the side of the base 1 facing the display screen 7.

[0032] The upper end of the telescopic rod set 4 is rotatably connected to the base 1, the telescopic rod set 4 is arranged on the side away from the display screen 7, and the lower end of the telescopic rod set 4 is used for abutting against the table top; the display screen 7 is supported by the telescopic rod set 4 to ensure that the display screen 7 is stable on the table top. It should be noted that when the display screen 7 is switched between the vertical screen state and the horizontal screen state, the rotating shaft 2 needs to be rotated synchronously, so that the lower end of the telescopic rod set 4 always abuts against the table top. On the other hand, by rotating the telescopic rod set 4, the included angle between the telescopic rod set 4 and the display screen 7 can be changed, and then the pitch angle of the display screen 7 can be flexibly adjusted to the best display angle, effectively improving the use experience of the display screen 7.

[0033] As shown in Figure 4 and Figure 5 When assembling, the fixed plate 3 is connected to the display screen 7, and the telescopic rod set 4 supports the back of the display screen 7; when the display screen 7 needs to be placed in the vertical screen state, the telescopic rod set 4 is adjusted to the extended state; when the display screen 7 needs to be placed in the horizontal screen state, the rotating shaft 2 is rotated by a certain angle, so that the lower end of the telescopic rod set 4 abuts against the table top, and the telescopic rod set 4 is adjusted to the retracted state, thereby meeting the switching between the horizontal screen state and the vertical screen state of the display screen 7, effectively expanding the use scenarios of the display screen 7, and meeting the diversified application adaptation of the display screen 7.

[0034] In an embodiment of the utility model, the middle part of the fixed plate 3 is provided with an assembly hole 301, the assembly hole 301 is rotatably connected with the rotating shaft 2, the circumferential inner side of the assembly hole 301 is provided with a limiting structure 302, the circumferential outer side of the rotating shaft 2 is provided with a first limiting plate 201 and a second limiting plate 202; after the display screen 7 is switched from the horizontal screen state to the vertical screen state, the left side face of the first limiting plate 201 abuts against the right side face of the limiting structure 302, at this time, the lower end of the telescopic rod set 4 abuts against the table top; in addition, after the display screen 7 is switched from the vertical screen state to the horizontal screen state, the rotating shaft 2 is counterclockwise rotated, so that the right side face of the second limiting plate 202 abuts against the left side face of the limiting structure 302, at this time, the lower end of the telescopic rod set 4 abuts against the table top. By matching the first limiting plate 201 and the second limiting plate 202 with the limiting structure 302 respectively, the rotating fixed angle of the rotating shaft 2 can be quickly adjusted, the telescopic rod set 4 is adjusted to the corresponding position state, and meanwhile, the condition that the rotating shaft 2 rotates relative to the fixed plate 3 when the telescopic rod set 4 exerts a supporting force on the display screen 7 is prevented, thereby improving the stability when the telescopic rod set 4 supports the display screen 7.

[0035] It should be noted that the telescopic rod group 4 comprises a stroke slide rail 401, which is rotatably connected to the second side of the base 1 through the pitch rotation shaft 8. By adjusting the included angle between the stroke slide rail 401 and the display screen 7, the pitch angle of the display screen 7 can be flexibly adjusted to the best display angle, thereby improving the use experience of the display screen 7.

[0036] On the other hand, the stroke slide rail 401 is slidingly connected to the telescopic support 403. When the display screen 7 is in a vertical screen state, the telescopic rod group 4 needs to be adjusted to an extended state because the connection point of the display screen 7 and the fixed plate 3 is high. At this time, the telescopic support 403 is pulled out of the stroke slide rail 401 to the limit position, and the overall length of the telescopic rod group 4 is adapted to the display screen 7 placed in a vertical screen state, so as to form stable support for the display screen 7. When the display screen 7 is in a horizontal screen state, the telescopic rod group 4 needs to be adjusted to a retracted state because the connection point of the display screen 7 and the fixed plate 3 is low. At this time, the telescopic support 403 is pushed into the stroke slide rail 401 to the limit position, and the overall length of the telescopic rod group 4 is adapted to the display screen 7 placed in a horizontal screen state, so as to form stable support for the display screen 7.

[0037] Preferably, two positioning ports 402 are symmetrically arranged at the lower end of the stroke slide rail 401, and two installation grooves (not shown in the figure) are symmetrically arranged on the two sides of the telescopic support 403.

In the natural state, the supporting spring holds the positioning key 404 out of the installation groove. Each positioning key 404 is clamped and connected to one positioning port 402. When the telescopic rod group 4 is in an extended state, the telescopic support 403 is pulled out of the stroke slide rail 401 to the limit position. At this time, the positioning key 404 is no longer limited by the stroke slide rail 401, and the positioning key 404 is clamped and connected to the positioning port 402. In the absence of external interference, the telescopic rod group 4 stably maintains its own length, thereby stably supporting the display screen 7 placed in a vertical screen state.

[0038] When it is necessary to retract the length of the telescopic rod group 4, the two positioning keys 404 are pressed synchronously, and the supporting spring is squeezed and retracted, so that the positioning key 404 quickly enters the installation groove. At this time, the telescopic support 403 is no longer limited, and the telescopic support 403 can be easily pushed into the stroke slide rail 401 to the limit position, thereby stably supporting the display screen 7 placed in a horizontal screen state.

[0039] Preferably, the support foot 405 is integrally arranged at the lower end of the telescopic support 403, and the support foot 405 does not slide into the entry track 401 when the telescopic rod set 4 is in the retracted state, and the support foot 405 can provide a force point for the telescopic support 403 when the telescopic support 403 needs to be pulled out. In addition, the bottom surface of the support foot 405 is arc-shaped, which reduces the contact surface between the support foot 405 and the table top, makes the support foot 405 more easily stable on the table top, and reduces the influence of the flatness of the table top on the telescopic rod set 4.
