[0040] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not limited to the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the unspecified implementation conditions are usually the conditions in conventional experiments.

[0041] like Figure 1 and Figure 2 , which is a schematic structural diagram of the present invention, provides an upper and lower supporting bracket, including a first supporting rod mechanism 1 and two second supporting rod mechanisms 2 symmetrically arranged at the upper and lower ends of the first supporting rod mechanism 1 .

[0042] like Figure 3 As shown, the first support rod mechanism 1 includes a support screw 1-1, a rotating lifting assembly arranged in the middle of the support screw 1-1, two locking sleeves 1-4 arranged at both ends of the support screw 1-1, two telescopic tubes 1-5 connecting the two locking sleeves 1-4 and the rotating lifting assembly, and a connecting plate assembly rotatably mounted on the rotating lifting assembly, and the display or TV 3 is mounted on the connecting plate assembly. Preferably, the telescopic tube 1-5 is a plastic telescopic tube, which is convenient for adjusting the height of the bracket, while keeping the entire bracket integrated and optimizing the appearance.

[0043] The rotary lifting assembly includes a first lifting adjustment sleeve 1-2 threadedly connected to the support screw 1-1 and a second lifting adjustment sleeve 1-3 slidingly matched with the support screw 1-1. The second lifting adjustment sleeve 1-3 is not threadedly connected to the support screw 1-1, and a support surface 1-1a slidingly matched with the second lifting adjustment sleeve 1-3 is provided on the support screw 1-1. The second lifting adjustment sleeve 1-3 includes two sleeve parts 1-3a located at both axial ends of the first lifting adjustment sleeve 1-2 and a boss part 1-3b connecting the two sleeve parts 1-3a and located radially outside the first lifting adjustment sleeve 1-2. The two telescopic tubes 1-5 are fixedly connected to the two sleeve parts 1-3a respectively.

[0044] The connecting plate assembly includes a display connecting plate 1-6 that is rotatably matched with the boss portion 1-3b and a support plate 1-7 that limits the display connecting plate 1-6 to the boss portion 1-3b. A POM friction plate 1-8 is provided on the side of the support plate 1-7 that is away from the display connecting plate 1-6, wherein the support plate 1-7 and the POM friction plate 1-8 are fixed to the boss portion 1-3b via a plurality of first screws 1-9. A stainless steel friction plate 1-10 is provided between the display connecting plate 1-6 and the boss portion 1-3b to reduce wear.

[0045] like Figure 6 As shown, in order to facilitate the rotational cooperation between the display connecting plate 1-6 and the boss portion 1-3b, a rotation support shaft 1-3b1 is provided on the boss portion 1-3b, and an axis hole 1-6a for the rotation support shaft 1-3b1 to pass through is provided on the display connecting plate 1-6.

[0046] In order to facilitate the limiting of the horizontal and vertical screen switching of the display or TV 3, a rotation limit protrusion 1-3b2 is provided on the boss portion 1-3b and located outside the rotation support shaft 1-3b1. At the same time, a rotation adjustment groove 1-6b for the rotation limit protrusion 1-362 to pass through is provided on the display connecting plate 1-6. The rotation adjustment groove 1-6b is arc-shaped, and the central angle of the rotation adjustment groove 1-6b is 90 degrees.

[0047] like Figure 4 As shown, the second support rod mechanism 2 includes a support tube 2-1 and a height adjustment sleeve 2-2 which is rotationally limited at one end of the support tube 2-1 close to the first support rod mechanism 1. The height adjustment sleeve 2-2 is threadedly connected to the support screw 1-1 and is locked by a locking sleeve 1-4. The end of the support tube 2-1 away from the first support rod mechanism 1 abuts against the top wall 4 or the ground 5, thereby supporting the entire bracket between the top wall 4 and the ground 5.

[0048] The height adjustment sleeve 2-2 includes a rotation limit part 2-2a, a rotation support part 2-2b and a locking part 2-2c which are arranged in sequence, wherein the outer diameter of the rotation limit part 2-2a is smaller than the rotation support part 2-2b and extends into the support tube 2-1, and a thrust bearing 2-3 is provided between the rotation support part 2-2b and the support tube 2-1.

[0049] like Figure 7 As shown, a plurality of first grooves 2-2a1 are provided on the outer wall of the rotation limit portion 2-2a, which are arranged at intervals in the circumferential direction and extend axially along the rotation limit portion 2-2a. Two rolling elements 2-4 are arranged at intervals in each first groove 2-2a1. Two second grooves 2-1a are provided on the inner wall of the support tube 2-1, which cooperate with the two rolling elements 2-4 and extend circumferentially along the support tube 2-1. Preferably, the rolling element 2-4 is a metal ball, and accordingly, the first groove 2-2a1 and the second groove 2-1a are consistent with the radius of the rolling element 2-4, so that the rolling element 2-4 can roll between the first groove 2-2a1 and the second groove 2-1a.

[0050] In order to facilitate the installation of the rolling element 2-4, a through hole connected to the second groove 2-1a is provided on the support tube 2-1 for the rolling element 2-4 to be placed therein. At the same time, a removable hole plug 2-5 is provided in the through hole. When the rolling element 2-4 is installed, the hole plug 2-5 can be installed in the through hole to prevent the rolling element 2-4 from detaching.

[0051] In this example, the locking portion 2-2c has an outer conical surface, and the locking sleeve 1-4 has an inner conical surface that matches the outer conical surface. Thus, the locking portion 2-2c can extend into the locking sleeve 1-4, and the conical surfaces of the two match to achieve locking of the height adjustment sleeve 2-2.

[0052] In order to further optimize the implementation effect of the present invention, Figure 5 As shown, a cover plate 2-6 is fixed to one end of the support tube 2-1 away from the first support rod mechanism 1, and a buffer pad 2-7 is provided on the outer side of the cover plate 2-6, wherein the cover plate 2-6 is fixed to the support tube 2-1 by a second screw 2-8, and the buffer pad 2-7 is made of silicone and fixed to the cover plate 2-6 by adhesive. The buffer pad 2-7 is abutted against the top wall 4 or the ground 5, which can improve the stability of the support structure and also avoid damage to the top wall 4 or the ground 5.

[0053] The working principle of the present invention is:

[0054] After installing the two second support rod mechanisms 2 at both ends of the first support rod mechanism 2 respectively, the overall bracket is placed vertically between the top wall 4 and the ground 5, and the height adjustment sleeve 2-2 is rotated to make the height adjustment sleeve 2-2 move away from the locking sleeve 1-4. The rotation limit part 2-2a rotates relative to the support tube 2-1 and drives the support tube 2-1 to move toward the top wall 4 or the ground 5. At this time, the locking part 2-2c cooperates with the conical surface of the locking sleeve 1-4 to lock, and the entire bracket is stably fixed between the top wall 4 and the ground 5; the display or TV 3 is installed on the display connecting plate 1-6, and the rotation of the display connecting plate 1-6 can drive the display or TV 3 to switch between horizontal and vertical screens (such as Fig.10 and Fig.11 As shown), rotating the first lifting adjustment sleeve 1-2 can drive the second lifting adjustment sleeve 1-3 to rise or fall (as shown in Figure 8 and Fig. 9 As shown), the display or TV 3 can be lifted and lowered by rotating the second lifting adjustment sleeve 1-3. The second lifting adjustment sleeve 1-3 can drive the support screw 2-1 to rotate, thereby realizing a 360-degree rotation of the display or TV 3.

[0055] In summary, the bracket has a simple structure and is easy to install, and can realize the lifting and lowering of the monitor or TV, switching between horizontal and vertical screens, and 360-degree rotation.

[0056] The above examples are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent transformation or modification made according to the spirit of the present invention should be included in the protection scope of the present invention.
