Description

Technical Field

[0001] This utility model relates to the field of television technology, specifically to a rotatable centrally mounted television stand. Background Technology

[0002] Most existing TV stands are fixed structures. To adjust the viewing angle, the entire TV needs to be manually pushed, which is laborious and can easily cause the TV to shift. This is especially true for large-screen TVs. Manual adjustment not only requires more physical effort but may also cause the device to tip over due to uneven force. Furthermore, after rotation, the stand is prone to shifting due to external force. The stability of the support structure is insufficient, and long-term use can lead to deformation. Deformation not only shortens the lifespan of the stand but may also cause the TV to be placed on a tilted surface, thus affecting the levelness of the screen display. Utility Model Content

[0003] The purpose of this invention is to provide a rotatable centrally located TV stand with the advantage of automatically rotating the stand.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotatable television set center base, including a support frame, a drive motor installed on the right side of the bottom of the support frame's inner cavity, a drive gear installed on the output shaft of the drive motor, a gear ring meshing on the left side of the drive gear, an internal gear meshing inside the gear ring, a support column installed on the top of the internal gear, a cover installed on the top of the support frame by screws, a positioning frame installed above the upper end of the support column through the cover, positioning vertical plates installed on both sides of the back of the positioning frame, and a reinforcing horizontal plate installed on the upper end of the front of the positioning vertical plate.

[0005] As a preferred embodiment, a lower fixing plate is installed on the top of the box cover and outside the support column. The top of the lower fixing plate has a second positioning hole distributed in a ring. A circular fixing plate is installed above the lower fixing plate. The middle part of the circular fixing plate is sleeved on the surface of the upper end of the support column. The surface of the circular fixing plate has a first positioning hole distributed in a ring, symmetrical to the second positioning hole.

[0006] As a preferred embodiment, a positioning bracket is installed on the right side of the top of the circular fixed plate, a pull plate is installed at the upper end of the bent part of the positioning bracket, a positioning rod is installed at the bottom of the pull plate, and the lower end of the positioning rod passes through the positioning bracket and extends downward.

[0007] As a preferred embodiment, the outer ring of the top of the lower fixed plate is provided with an annular limiting groove, and an arc-shaped slider is slidably installed inside the annular limiting groove. The upper end of the arc-shaped slider is connected to the outer ring of the bottom of the circular fixed plate.

[0008] As a preferred embodiment, the gear ring has a through-groove design in the middle and teeth installed on the inner wall. The bottom of the gear ring is connected to the bottom of the inner cavity of the support frame via a connecting shaft and a bearing.

[0009] As a preferred embodiment, a limiting spring is sleeved on the lower end of the positioning rod, the upper end of the limiting spring is connected to the bottom of the upper bent part of the positioning bracket, and the lower end of the positioning rod passes through the first positioning hole and is engaged inside the second positioning hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a drive motor to drive the active gear, gear ring, and internal gear transmission, thereby driving the TV on the support column and positioning frame to rotate. No manual pushing is required, making operation convenient. Under the action of the limit spring, the positioning rod can be stably locked in the first positioning hole and the second positioning hole to prevent the TV from shifting after rotation. Pulling up the pull plate can release the positioning and facilitate angle adjustment.

[0011] 2. This utility model effectively avoids the installation space of the internal gear by adopting a through-groove design in the middle of the gear ring. The teeth on the inner wall can simultaneously form a stable mesh with the driving gear and the internal gear, ensuring that the power of the drive motor can be accurately transmitted to the internal gear and the support column, providing a reliable power transmission foundation for the rotation of the TV. The limiting spring sleeved on the lower end of the positioning rod, through the connection between the upper end and the bottom of the bent part of the positioning bracket, can always provide a downward elastic force to the positioning rod, so that the lower end of the positioning rod can be tightly locked inside the first positioning hole and the second positioning hole, effectively preventing the positioning rod from dislodging from the positioning hole due to vibration or slight contact, and ensuring the stability of the TV angle fixation.

[0014] 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.

[0015] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0016] Example 1: Please see Figure 1 As shown, this utility model provides a rotatable central base for a television, including a support frame 1. A drive motor 2 is installed on the right side of the bottom of the inner cavity of the support frame 1. A drive gear 3 is installed on the output shaft of the drive motor 2. A gear ring 4 meshes with the left side of the drive gear 3. An internal gear 5 meshes with the inside of the gear ring 4. A support column 6 is installed on the top of the internal gear 5. A cover 20 is installed on the top of the support frame 1 by screws. The upper end of the support column 6 passes through the cover 20 and extends to the top to install a positioning frame 7. Positioning vertical plates 8 are installed on both sides of the back of the positioning frame 7. A reinforcing horizontal plate 9 is installed on the upper end of the front of the positioning vertical plate 8.

[0017] This technical solution uses a drive motor 2 to drive the active gear 3, gear ring 4, and internal gear 5 to rotate the TV on the support column 6 and positioning frame 7. It does not require manual pushing and is easy to operate. Under the action of the limiting spring 19, the positioning rod 18 can be stably locked in the first positioning hole 13 and the second positioning hole 11 to prevent the TV from shifting after rotation. Pulling up the pull plate 17 can release the positioning and facilitate angle adjustment.

[0018] Example 2: Based on Embodiment 1, this utility model is as follows: Figure 4As shown, a lower fixing plate 10 is installed on the top of the box cover 20 and outside the support column 6. The top of the lower fixing plate 10 is provided with second positioning holes 11 arranged in a ring. A circular fixing plate 12 is installed above the lower fixing plate 10. The middle part of the circular fixing plate 12 is sleeved on the surface of the upper end of the support column 6. The surface of the circular fixing plate 12 is provided with first positioning holes 13 arranged in a ring, which are symmetrical to the second positioning holes 11.

[0019] Adopting such Figure 1 The technical solution shown provides a precise engagement position for the positioning rod 18 through the second positioning hole 11 and the symmetrically opened first positioning hole 13, ensuring that the support column 6 can quickly and stably position the TV after rotating to the target angle, effectively avoiding displacement caused by external force.

[0020] Secondly, in the technical solution, a positioning bracket 16 is installed on the right side of the top of the circular fixed plate 12. A pull plate 17 is installed at the upper end of the bent part of the positioning bracket 16, and a positioning rod 18 is installed at the bottom of the pull plate 17. The lower end of the positioning rod 18 passes through the positioning bracket 16 and extends downward. An annular limiting groove 14 is opened on the outer ring of the top of the lower fixed plate 10. An arc-shaped slider 15 is slidably installed inside the annular limiting groove 14. The upper end of the arc-shaped slider 15 is connected to the outer ring of the bottom of the circular fixed plate 12.

[0021] Its adoption is as follows Figure 1 The technical solution shown allows the positioning rod 18 to disengage from the positioning hole by pulling the pull plate 17 upwards, facilitating quick adjustment of the TV's rotation angle. After releasing the pull plate 17, the positioning rod 18 naturally falls back to its original position. With the subsequent limit spring 19, automatic locking and positioning can be achieved, making the operation simple and responsive. The annular limit groove 14 and the arc-shaped slider 15 can precisely guide the rotation trajectory of the circular fixed plate 12, preventing radial offset or jamming of the circular fixed plate 12 when rotating with the support column 6. This ensures the smoothness of the rotation process and enhances the connection stability between the circular fixed plate 12 and the lower fixed plate 10 through the close support of the arc-shaped slider 15 and the annular limit groove 14. This, in turn, improves the load-bearing balance of the upper end of the support column 6, allowing the entire base to maintain good structural stability and ease of operation during rotation adjustment and positioning.

[0022] Example 3: This utility model is as follows Figures 1-5 As shown, the gear ring 4 has a through groove design in the middle and teeth installed on the inner wall. The bottom of the gear ring 4 is connected to the bottom of the inner cavity of the support frame 1 through a bearing via a connecting shaft. The lower end of the positioning rod 18 is sleeved with a limit spring 19. The upper end of the limit spring 19 is connected to the bottom of the upper bent part of the positioning bracket 16. The lower end of the positioning rod 18 passes through the first positioning hole 13 and is engaged inside the second positioning hole 11.

[0023] Using the above technical solution, the gear ring 4 adopts a through-groove design in the middle, which can effectively avoid the installation space of the internal gear 5. The teeth on the inner wall can simultaneously form a stable mesh with the drive gear 3 and the internal gear 5, ensuring that the power of the drive motor 2 can be accurately transmitted to the internal gear 5 and the support column 6, providing a reliable power transmission foundation for the rotation of the TV. The limiting spring 19, which is sleeved on the lower end of the positioning rod 18, can always provide a downward elastic force to the positioning rod 18 through the connection between the upper end and the bottom of the bent part of the positioning bracket 16. This allows the lower end of the positioning rod 18 to be tightly locked inside the first positioning hole 13 and the second positioning hole 11, effectively preventing the positioning rod 18 from dislodging from the positioning hole due to vibration or slight contact, and ensuring the stability of the TV angle fixation.

[0024] The working principle of this utility model is as follows: First, the positioning rod 18 is moved upward by the pull plate 17, so that its lower end moves out of the second positioning hole 11 and the pull plate 17 is fixed. Then, the drive motor 2 is started. The output shaft of the drive motor 2 drives the drive gear 3 to drive the transmission. The drive gear 3 rotates through the cooperation with the gear ring 4. At this time, the internal gear 5 inside the gear ring 4 rotates accordingly, which drives the support column 6 to rotate synchronously. The upper end of the support column 6 drives the TV to rotate through the positioning frame 7, which can realize the rotation adjustment of the TV angle. When the angle needs to be fixed, the drive motor 2 is turned off. The positioning rod 18 is kept in position under the action of the limit spring 19. When adjusting again, the pull plate 17 is pulled up to make the positioning rod 18 disengage from the second positioning hole 11, and the drive motor 2 can be started to rotate.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
