Description

Technical Field

[0001] This utility model relates to the field of television stand technology, and in particular to an adjustable television stand. Background Technology

[0002] A television set is a device that uses electronic technology to transmit moving images and audio signals based on the persistence of vision and visual psychology of the human eye. It is also an important broadcasting and video communication tool. The basic system of a television set consists of three parts: camera, transmission, and display. In daily life, television sets are generally installed in two ways: wall-mounted and floor-standing.

[0003] TV stands are typically used to mount televisions. Currently, because televisions have multiple ports, when connecting these ports, the television needs to be moved a certain distance away from the wall to facilitate cable connections. Existing TV stands also require disassembly and replacement with a suitable stand if a different sized television is desired after installation. Height adjustment is cumbersome, requiring the removal and retightening of the fixing bolts after adjustment. Therefore, they lack practical applicability in real-world applications.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present utility model. This embodiment provides an adjustable TV stand that can adjust the height of the TV and fix TVs of different sizes. It includes a support base 100.

[0034] The longitudinal adjustment unit 200 includes a fixed column 201 fixedly mounted on the support base 100, and a lifting component 202 is provided on the support base 100.

[0035] The installation unit 300 includes a fixed frame 301 mounted on the lifting component 202, a transmission component 303 mounted on the fixed frame 301, a slider 306 mounted on the transmission component 303, and an angle adjustment component 307 mounted on the slider 306.

[0036] In use, the angle adjustment component 307 is driven to a position that matches the size of the TV by the transmission component 303. Then, the TV is fixed by the angle adjustment component 307. The angle adjustment component 307 can then be pushed or pulled to a suitable position to adjust the tilt angle of the TV. After installation, the vertical position of the TV can be adjusted by the lifting component 202 for better viewing.

[0037] Example 2

[0038] Reference Figures 2 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the lifting component 202 includes a mounting groove 202a opened on the support base 100, a worm gear 202b rotatably provided on the mounting groove 202a, a worm wheel 202c rotatably provided on the mounting groove 202a, a first threaded rod 202d rotatably provided on the worm wheel 202c, a lifting block 202e slidably provided on the fixed column 201, a threaded groove opened on the lifting block 202e, the first threaded rod 202d being threadedly connected to the lifting block 202e, and a lifting groove 201a opened on the fixed column 201, the inner wall of the lifting groove 201a being tightly fitted with the lifting block 202e.

[0039] Rotating the worm gear 202b drives the worm wheel 202c to rotate, which in turn drives the first threaded rod 202d to rotate, thereby causing the lifting block 202e to move longitudinally on the lifting groove 201a, so that the height of the TV can be adjusted according to actual needs.

[0040] A motor 302 is fixedly mounted on a fixed frame 301. The transmission component 303 includes a starting bevel gear 303a fixedly mounted on the output end of the motor 302, a connecting rod 303b rotatably mounted on the fixed frame 301, a connecting bevel gear 303c fixedly mounted on one end of the connecting rod 303b, and a transmission bevel gear 303d fixedly mounted on the other end of the connecting rod 303b. A second threaded rod 303e is rotatably mounted on the fixed frame 301, a rotating bevel gear 303f fixedly mounted on one end of the second threaded rod 303e, and a third threaded rod 305 fixedly mounted on the other end of the second threaded rod 303e. The thread direction of the third threaded rod 305 is opposite to that of the second threaded rod 303e. A sliding groove 304 is provided on the fixed frame 301. A slider 306 is screwed onto both the second threaded rod 303e and the third threaded rod 305. The starting bevel gear 303a meshes with the connecting bevel gear 303c, and the transmission bevel gear 303d meshes with the rotating bevel gear 303f.

[0041] When motor 302 is turned on, the output of motor 302 drives the connecting bevel gear 303c to rotate through the starting bevel gear 303a. Under the action of connecting rod 303b, the rotating bevel gear 303f is driven to rotate through the transmission bevel gear 303d. In turn, the second threaded rod 303e and the third threaded rod 305 drive the sliders 306 on both sides to move closer or further apart, so that they can be adjusted according to the actual size of the TV.

[0042] Angle adjustment component 307 includes a connecting bracket 307a mounted on a slider 306, a first connecting plate 307b pivotally connected to the connecting bracket 307a, a second connecting plate 307c pivotally connected to the first connecting plate 307b, a mounting bracket 307d mounted on the second connecting plate 307c, a limiting part on the pivot side of the first connecting plate 307b, a limiting groove on the second connecting plate 307c, the limiting part being located within the limiting groove to limit the maximum unfolding angle, a friction plate 307f pivotally mounted on the first connecting plate 307b, an adjusting plate below the friction plate 307f, and an adjusting screw 307e screwed onto the pivot of the first connecting plate 307b, the adjusting screw 307e passing through the adjusting plate.

[0043] A friction plate is also provided at the end where the first connecting plate 307b is pivotally connected to the connecting bracket 307a. This friction plate allows for better control of the friction between the first connecting plate 307b and the connecting bracket 307a, thus facilitating better suspension of the first connecting plate 307b during rotation. The friction plates 307f on the first connecting plate 307b and the second connecting plate 307c serve the same purpose. The friction between them can be controlled by turning the adjusting screw 307e. Furthermore, the first connecting plate 307b is provided with protrusions to prevent excessive rotation angles and uneven force distribution during rotation. The imbalance causes the first connecting plate 307b and the second connecting plate 307c to break. The limiting part on the first connecting plate 307b and the limiting groove on the second connecting plate 307c both serve this purpose. During use, the viewer can pull the TV forward or backward, and then apply pulling or pushing force to the left or right to adjust the angle of the TV, so that the viewer can have a better viewing effect. At the same time, the mounting bracket 307d is equipped with a tilt adjuster. This adjuster is existing technology. The tilt angle of the mounting bracket 307d can be controlled by the cooperation of the locking handle and the adjusting column.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
