[0014] Compared with the prior art, the present invention provides a TV cabinet convenient for adjusting the position of a TV, having the following beneficial effects: 1. The present invention uses the air pressure difference inside the first suction cup of the suction cup fixing front-back moving device to apply a pressure perpendicular to the fixing plane direction to the TV, fixing the TV on the surface of the TV cabinet. When the TV needs to be disassembled, by opening the air vent hole inside the first suction cup, the air pressure inside the first suction cup is communicated with the external air pressure.

When it is necessary to disassemble the up-down and left-right moving device, by removing the sliding connection block, the connection between the friction increasing device and the second telescopic device is disconnected, so that the second telescopic device no longer provides upward support force for the friction increasing device, and then the up-down and left-right moving device can be disassembled. In this way, the disassembly time of the TV cabinet that facilitates the adjustment of the TV position is reduced through the above content.

[0017] 4. The present invention drives the TV to rotate at different plane angles through the double-sided 360-degree rotation device. When it is necessary to disassemble the TV from the double-sided 360-degree rotation device, by rotating the direction of the rotation limiting device to make it leave the first compression spring, then the first limit block can be moved, and then the TV can be taken out. In this way, the disassembly time of the TV cabinet that facilitates the adjustment of the TV position is reduced through the above content. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation of the present invention.

[0022] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example 1, please refer to Figures 1-4, the present invention provides a technical solution: a TV cabinet facilitating the adjustment of the TV position, including a first TV cabinet 1, and a sucker fixing and front-back moving device 2 is arranged inside the first TV cabinet 1; the sucker fixing and front-back moving device 2 includes a sucker fixing device 201 which is used to connect the sucker fixing and front-back moving device 2 with the first TV cabinet 1. A bottom of the sucker fixing device 201 is fixedly connected with an L-shaped connecting rod 202 which is used to provide a supporting force for the gravity received by a T-shaped through shaft sleeve 203. An axis of the L-shaped connecting rod 202 is perpendicular to an axis of a sucker of the sucker fixing device 201. One end of the L-shaped connecting rod 202 away from the sucker fixing device 201 is fixedly connected with the T-shaped through shaft sleeve 203 which is used to cooperate with a T-shaped fixing shaft 204 to reduce the air pressure inside the sucker fixing device 201 by using gravity, so as to increase the stability of the sucker fixing and front-back moving device 2. An axis of the T-shaped through shaft sleeve 203 is perpendicular to the axis of the sucker of the sucker fixing device 201, and the axis of the T-shaped through shaft sleeve 203 coincides with the axis of the T-shaped fixing shaft 204. The T-shaped through shaft sleeve 203 is fixedly connected with the sucker fixing device 201. A T-shaped fixing shaft 204 is slidably connected inside the T-shaped through shaft sleeve 203. One end of the T-shaped fixing shaft 204 away from the T-shaped through shaft sleeve 203 is fixedly connected with a first telescopic device 205 whose axis is parallel to the axis of the sucker of the sucker fixing device 201. A fixing groove 206 is formed at one end of the first telescopic device 205 away from the T-shaped fixing shaft 204. An inner wall of the fixing groove 206 is a relatively rough surface, and an up-down and left-right moving device 3 is fixedly connected inside the fixing groove 206.

[0024] The whole sucker fixing and front-back moving device 2 is fixed on the surface of the first TV cabinet 1 through the sucker fixing device 201. The sucker fixing and front-back moving device 2 connects the TV set with the first TV cabinet 1. In this process, the T-shaped fixing shaft 204 slides downward inside the T-shaped through shaft sleeve 203 under the influence of the gravity of the TV set. Since the T-shaped through shaft sleeve 203 is communicated with the air pressure inside the sucker fixing device 201, with the movement of the T-shaped fixing shaft 204, the space inside the sucker fixing device 201 increases in a disguised form, the air pressure inside the sucker fixing device 201 is reduced, and the air pressure difference is enhanced.

[0025] The sucker fixing device 201 includes a first support rod 2011 which is used to enhance the resistance of the first sucker 2012 to lateral shear force. The length of the part of the first support rod 2011 inside the first TV cabinet 1 is greater than the exposed part. The first support rod 2011 is slidably connected to the first TV cabinet 1. The cylindrical surface of the first support rod 2011 is fixedly connected to an L-shaped connecting rod 202. The cylindrical surface of the first support rod 2011 is fixedly connected with a first sucker 2012. An air vent is arranged on the surface of the first sucker 2012, which is used to more conveniently connect the air pressure inside the first sucker 2012 with the external air pressure. The axis of the first sucker 2012 coincides with the axis of the first support rod 2011. The first sucker 2012 is fixedly connected to a T-shaped through bushing 203. The cylindrical surface of the first support rod 2011 is fixedly connected with a second connecting rod 2013. The second connecting rod 2013 is located on the side of the first sucker 2012 away from the first TV cabinet 1. The axis of the second connecting rod 2013 is perpendicular to the axis of the first support rod 2011. A small air extraction device 2014 is fixedly connected to the top of the second connecting rod 2013. The small air extraction device 2014 is used to extract the air inside the first sucker 2012, reduce the air pressure inside the first sucker 2012, and enhance the adsorption force of the first sucker 2012.

[0026] Insert the first support rod 2011 into the first TV cabinet 1, then bring the first sucker 2012 close to the surface of the first TV cabinet 1, and then use the small air extraction device 2014 to suck out the air inside the first sucker 2012, thereby reducing the internal air pressure of the first sucker 2012. Since the internal air pressure of the first sucker 2012 changes and is less than the external air pressure, an air pressure difference is generated. The air pressure difference generates a pressure that presses the first sucker 2012 tightly against the surface of the first TV cabinet 1, thereby restricting the axial movement of the first support rod 2011. When it is necessary to detach the sucker fixing front-back moving device 2 from the first TV cabinet 1, open the air vent on the surface of the first sucker 2012 to connect the air inside the first sucker 2012 with the external air. Then the air between the two gradually becomes the same, so the pressure difference that generates the pressure disappears. Just move the sucker fixing front-back moving device 2 in the direction away from the first TV cabinet 1 along the axis of the first support rod 2011, and then the sucker fixing front-back moving device 2 can be disassembled.

[0027] Embodiment 2, on the basis of Embodiment 1, please refer to Figures 5-8, the present invention provides a technical solution: The up-down and left-right moving device 3 includes a first fixing block 301. The first fixing block 301 is located inside the fixing groove 206. A second fixing block 302 is movably connected inside the first fixing block 301. The number of the second fixing blocks 302 is two and they are symmetric along the axis of the first telescopic device 205. An anti-slip device 303 is movably connected inside the first fixing block 301. The anti-slip device 303 is used to increase the friction between the second fixing block 302 and the fixing groove 206. The anti-slip device 303 is located between the two second fixing blocks 302. One side of the first fixing block 301 away from the suction cup fixing front-back moving device 2 is fixedly connected with an up-down moving device 304. The up-down moving device 304 is used to drive the TV to move up and down. A second telescopic device 305 is fixedly connected inside the up-down moving device 304. The moving direction of the up-down moving device 304 is parallel to the axis of the second telescopic device 305. A sliding connection block 306 is slidably connected to the top of the second telescopic device 305. The sliding connection block 306 is used to connect the second telescopic device 305 and the anti-slip device 303. And during the process that the second telescopic device 305 drives the anti-slip device 303 to move upward, the pressure between the second telescopic device 305 and the anti-slip device 303 will increase, making the connection between the two closer. The bottom of the sliding connection block 306 is slidably connected to the anti-slip device 303. One end of the up-down moving device 304 away from the first fixing block 301 is fixedly connected with a first left-right moving device 307. A double-sided 360-degree rotating device 4 is fixedly connected to the up-down and left-right moving device 3 in the direction away from the suction cup fixing front-back moving device 2.

[0028] Insert the anti-slip device 303 into the bottom of the first fixing block 301, then place the first fixing block 301 into the fixing groove 206. Then connect the anti-slip device 303 and the second telescopic device 305 through the sliding connection block 306. Then the second telescopic device 305 extends to drive the anti-slip device 303 to move upward, squeezing the second fixing block 302 to increase the pressure between it and the fixing groove 206. During this process, the pressure between the anti-slip device 303 and the sliding connection block 306 will also increase. When it is necessary to detach the up-down and left-right moving device 3 from the suction cup fixing front-back moving device 2, retract the second telescopic device 305, then pull out the sliding connection block 306 to disconnect the connection between the second telescopic device 305 and the anti-slip device 303. Then move the first fixing block 301 upward to make it leave the inside of the fixing groove 206.

[0029] The double-sided 360-degree rotation device 4 includes a first planar rotation device 401 which is used to drive the TV set to perform 360-degree rotation in the vertical plane. The first planar rotation device 401 is fixedly connected to the first left-right movement device 307. One end of the first planar rotation device 401 away from the sucker fixed front-back movement device 2 is fixedly connected to a second planar rotation device 402. A third fixed block 403 is fixedly connected to the surface of the rotation axis of the second planar rotation device 402. A first limiting block 404 is movably connected inside the third fixed block 403. The arc surface at the top of the first limiting block 404 is used to transfer part of the downward pressure to both sides. The number of the first limiting blocks 404 is two, symmetrically arranged along the axis of the first telescopic device 205. A limiting device 405 is fixedly connected to the surface of the first limiting block 404. The number of the limiting devices 405 is four, evenly distributed on the two first limiting blocks 404. A first compression spring 406 is fixedly connected to the surface of the third fixed block 403. The first compression spring 406 is movably connected to the limiting device 405. The number of the first compression springs 406 is the same as that of the limiting devices 405. The first compression spring 406 is used to limit the degree of freedom of the first limiting block 404 and at the same time provide a certain amount of movement space for the first limiting block 404.

[0030] When it is necessary to connect the TV set to the double-sided 360-degree rotation device 4, since the shape above the first limiting block 404 is arc-shaped, during the process of clamping the TV set into the double-sided 360-degree rotation device 4, the clamping block of the TV set exerts a downward pressure on the first limiting block 404. Due to the arc surface of the first limiting block 404, part of the downward pressure will be converted into pressure on both sides. Then the first limiting block 404 transfers the pressure on both sides to the first compression spring 406, and then the first compression spring 406 is compressed. Immediately, the first limiting block 404 moves towards the direction close to the first compression spring 406, and then the TV set is connected to the double-sided 360-degree rotation device 4. When it is necessary to disconnect the connection between the TV set and the double-sided 360-degree rotation device 4, rotate the limiting device 405 to disconnect the connection between the rotating limiting device 405 and the first compression spring 406, so that the connection between the first compression spring 406 and the first limiting block 404 is disconnected. Then move the first limiting block 404, and then take out the TV set.
