Description

Technical Field

[0001] The utility model belongs to the technical field of display bases, and particularly relates to an all-round adjustable display base. Background Art

[0002] A display base is a bracket for supporting a display, which has the functions of fixing and supporting the display to ensure its stable placement on a desktop or other plane. With the development of technology, the design of display bases is also constantly innovating. For example, there is a design that makes height adjustment more convenient through structures such as slide rail components and elastic members, and does not require the use of bolts for fastening, thus solving the problems of cumbersome adjustment and easy thread slipping of bolts in traditional designs. Another design realizes quick adjustment of the base height and convenient disassembly and assembly through the card slots and positioning members on the connecting seat and the supporting seat.

[0003] However, in the existing display bases, the angle of the display is not convenient to adjust the inclination. When the inclination angle of the display is adjusted too large, the display is likely to directly contact the placed plane under the action of gravity and cannot rotate in all directions.

[0033] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below in conjunction with the drawings and embodiments.

[0034] As Figures 1-9 shown, an all-round adjustable display screen base includes a base 1, a first rotating seat 2 is rotatably connected above the base 1, a second rotating seat 3 for fine-tuning the display screen is rotatably connected above the first rotating seat 2, and an angle adjustment mechanism 4 for adjusting the tilt angle of the display screen is provided above the second rotating seat 3;

[0035] The angle adjustment mechanism 4 includes two connecting seats 41. A through hole is provided in the middle of the connecting seat 41. A rotating rod 42 is rotatably connected in the middle of the two connecting seats 41. The middle of the rotating rod 42 is connected with a display screen 5 through a connecting member. A sleeve 43 with a first positioning tooth 431 arranged in an annular array is fixedly connected to the outer end of one connecting seat 41. A rotating block 421 is fixedly connected to the outer end of the rotating rod 42 outside the sleeve 43. The rotating block 421 is provided with a second positioning tooth 422 having the same tooth shape as the first positioning tooth 431. A rotating cap 45 is coupled to the outside of the first positioning tooth 431 and the second positioning tooth 422.

[0036] Adopting the technical solution of this embodiment, the first rotating seat 2 is used to make the display screen 5 rotate in all directions, the second rotating seat 3 is used to finely adjust the display screen 5, and the angle adjustment mechanism 4 is used to adjust the tilt angle of the display screen 5. In the angle adjustment mechanism 4, when the rotating cap 45 is disengaged from the first positioning tooth 431 and the second positioning tooth 422, the display screen 5 is tilted by driving the rotating block 421 to rotate. After the tilt angle of the display screen 5 is adjusted, the rotating cap 45 is coupled with the first positioning tooth 431 and the second positioning tooth 422, so that the rotation angle of the rotating block 421 is fixed, thereby fixing the tilt angle of the display screen 5.

[0037] Refer to Figures 4-5 As shown in FIGS. 8 and 9: A plurality of positioning grooves arranged in an annular array are provided on the upper side of the base 1. A sliding groove 21 is provided on the lower side of the first rotating seat 2. A positioning rod 22 is slidably connected in the sliding groove 21. The height of the positioning rod 22 is the same as the height of the sliding groove 21. The height of the positioning groove is half of the height of the sliding groove 21; Positioning blocks 221 are fixedly connected to both sides of the positioning rod 22. The positioning blocks 221 are located on the upper half side of the positioning rod 22. Sliding grooves for the positioning blocks 221 are provided on both sides of the positioning groove.

[0038] In this embodiment, the cooperation between the positioning block 221 and the sliding groove is used to prevent the positioning rod 22 from being pulled out of the positioning groove. By providing the positioning block 221 on the upper plate side of the positioning block 221, no matter whether the lower half of the positioning rod 22 is located in the positioning groove, the positioning block 221 is in sliding contact with the sliding groove, so that the positioning rod 22 can be prevented from sliding out.

[0039] Refer to Figure 9 A rotating handle 222 is fixedly connected to the outer end of the positioning rod 22.

[0040] In this embodiment, the rotating handle 222 is used to drive the positioning rod 22 to move up and down. When the positioning rod 22 is located above the positioning groove, the first rotating seat 2 is driven to rotate by a limited angle through the rotating handle 222.

[0041] Refer to Figures 6-7: A circular groove 23 is formed on the upper side of the first rotating seat 2. Two baffles 231 are fixedly connected inside the groove 23 of the first rotating seat 2. A circular seat 31 rotatably connected to the groove 23 is fixedly connected below the second rotating seat 3. A positioning plate 32 located between the two baffles 231 is fixedly connected to the outer side of the circular seat 31. A damping rubber 33 is fixedly connected to the outer side of the circular seat 31. The outer side of the damping rubber 33 is in contact with the outer side of the groove 23 of the first rotating seat 2. The damping rubber 33 is provided with arc-shaped notches on both sides of the positioning plate 32, and the included angle between the arc-shaped notches is twice the included angle between the two baffles 231.

[0042] In this embodiment, the positioning plate 32 rotates between the two baffles 231. The damping rubber 33 is used to increase the frictional force between the circular seat 31 and the groove of the first rotating seat 2. Only when the external force is greater than the frictional force can the second rotating seat rotate relative to the first rotating seat 2.

[0043] Refer to Figure 4 and 6 : The included angle between the two baffles 231 is equal to the included angle between the two positioning grooves.

[0044] In this embodiment, by restricting the included angle between the two baffles 231, the angle range that the second rotating seat 3 can rotate is adjusted. The rotation range of the second rotating seat 3 is equal to the included angle between the two positioning grooves. Thus, after adjusting the first rotating seat 2, the second rotating seat 3 can be finely adjusted within the included angle range of the positioning grooves.

[0045] Refer to Figure 1 : A moving block 34 is fixedly connected to the outer side of the second rotating seat 3.

[0046] In this embodiment, the moving block 34 is used to drive the first rotating seat 3 to rotate, thereby finely adjusting the rotation angle of the display screen 5.

[0047] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
