Description

Technical Field

[0001] This utility model relates to the field of interior design technology, specifically to an adjustable television stand. Background Technology

[0002] A TV wall mount is a peripheral device specifically designed for mounting flat-screen TVs and LCD TVs on the wall. It is suitable for use in living rooms, bedrooms, offices, conference rooms, exhibition halls, hotels, airports, train stations, hospitals, bus stations, shopping malls, and other places.

[0003] Patent publication number CN212430391U discloses an adjustable TV wall mount, including a fixed base plate, a TV panel, and a connecting assembly connecting the fixed base plate and the TV panel. The connecting assembly includes an I-shaped frame vertically arranged on the front of the fixed base plate and a connecting column movably connected to the I-shaped frame by a first screw. The other end of the connecting column is fixedly connected to a universal ball joint. The ball seat of the universal ball joint is fixedly connected to the back of the TV panel. The TV body is fixed to the front of the TV panel by bolts.

[0004] To address the issue that conventional TV wall mounts can only fix the TV in one position and cannot meet people's usage needs, existing technology uses a remote controller to control the rotation of a drive motor, which in turn drives a slider to move on a fixed base plate via a drive screw. Then, through the transmission of an adjusting linkage, the TV body is swung, thus adjusting the TV's vertical angle. However, this still results in the TV being fixed to the bracket and unable to be moved, and the bracket being relatively high, requiring users to look up to watch the TV. This leads to problems such as users not being able to watch TV for long periods and the risk of neck injury from looking up for extended periods. Utility Model Content

[0008] The adjustment mechanism includes a base plate, a lifting groove fixedly connected to the top surface of the base plate, a drive motor fixedly connected to one side of the bottom surface of the inner cavity of the lifting groove, a partition fixedly connected to the bottom of the inner side of the base plate, a top plate fixedly connected to the top surface of the base plate, one end of the output shaft of the drive motor passing through the top surface of the partition and fixedly connected to a lead screw, one end of the lead screw being rotatably connected to the inside of the bottom surface of the top plate, a slide rod fixedly connected to one side of the top surface of the partition, one end of the slide rod being fixedly connected to the bottom surface of the top plate, and a lifting block threadedly connected to the side of the lead screw, the lifting block being slidably connected to the side of the slide rod.

[0009] A further improvement of this utility model is that: a roller is fixedly connected to the bottom surface of the base plate, and a screw is threadedly connected to the top surface of the base plate. There are two screws, which are symmetrically distributed on both sides of the top surface of the base plate. A turntable is fixedly connected to one end of the screw, and a pressure plate is rotatably connected to the other end of the screw through the bottom surface of the base plate. A rubber pad is fixedly connected to the bottom surface of the pressure plate.

[0010] A further improvement of the present invention is that: a connecting plate is fixedly connected to the side of the lifting block by a nut, a rotating shaft is fixedly connected to the top surface of the connecting plate, a stud is fixedly connected to the top surface of the connecting plate, a rotating block is rotatably connected to the side of the rotating shaft, an arc-shaped groove is provided on the top surface of the rotating block, and the stud is movably connected inside the arc-shaped groove.

[0013] A further improvement of this utility model is that: a fixing nut is threaded inside the threaded hole, the fixing nut is movably connected to the limiting plate, and a knob is fixedly connected to one end of the fixing nut.

[0014] A further improvement of this utility model is that: the side of the support plate has two through holes, a telescopic bottom rod is fixedly connected inside the through holes, a telescopic rod is slidably connected inside the telescopic bottom rod, a limit nut is threadedly connected to one end of the telescopic bottom rod, and a limit plate is fixedly connected to one end of the telescopic rod.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides an adjustable TV stand, which employs an adjustment mechanism, a base plate, a lifting groove, a drive motor, a partition, a top plate, a lead screw, a slide rod, a lifting block, rollers, a screw rod, a turntable, a pressure plate, and rubber pads. When the position of the TV body needs to be moved, the base plate is pushed to rotate the rollers, moving the base plate to the designated position. After the base plate moves to the designated position, the turntable rotates, driving the screw rod to rotate. The screw rod is connected to the base plate, and one end of the screw rod drives the pressure plate to move downwards and press against the ground to restrict the movement of the base plate. The rubber pads can increase the friction between the pressure plate and the ground, improving the pressure plate's ability to control the movement of the base plate. To address the stability limitations, when adjusting the height of the television set, the drive motor is activated to rotate the lead screw. The rotation of the lead screw causes the lifting block to rise and fall. The sliding rod connects to the lifting block to support it and improve its stability. As the lifting block rises and falls, the television set is raised and lowered via a fixing device, thus adjusting its height. Once the television set reaches the appropriate height, the drive motor is turned off, stopping the lead screw. The lead screw then connects to the lifting block to fix its height. The lifting block, through the fixing device, secures the height of the television set, improving the adaptability of the device.

[0017] 2. This utility model provides an adjustable TV stand, which employs a fixing mechanism, support plate, column holes, threaded holes, limiting columns, limiting plate one, fixing nut, knob, through hole, telescopic base rod, telescopic rod, limiting nut, and limiting plate two in cooperation. By rotating the knob according to the size of the TV body, the fixing nut is rotated. The fixing nut is connected to the threaded hole and limiting plate one. When the fixing nut rotates, it causes limiting plate one to rise and fall, thereby adjusting the height of limiting plate one. When limiting plate one rises and falls, it causes the two limiting columns to slide in the two column holes respectively. The two limiting columns are connected to limiting plate one, which controls the movement direction of limiting plate one. The device restricts movement and improves the stability of the lifting and lowering of the first limiting plate. After the first limiting plate reaches the appropriate height, the knob stops rotating, causing the fixing nut to stop rotating, thus fixing the height of the first limiting plate. The TV body is placed on the first limiting plate, and the two second limiting plates are pushed to move the telescopic rod in the telescopic base rod so that the two second limiting plates are attached to the sides of the TV body. The limiting nut is rotated to restrict the sliding of the telescopic rod in the telescopic base rod. The two telescopic base rods connect the telescopic rod and the second limiting plate to clamp and fix the two sides of the TV body, preventing the TV body from falling off the fixing device and improving the adaptability of the device.

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5As shown, this utility model provides an adjustable TV stand, including an adjustment mechanism 1, a fixing mechanism 2 on the side of the adjustment mechanism 1, and a TV body 3 on the side of the fixing mechanism 2. The adjustment mechanism 1 includes a base plate 101, a lifting groove 102 fixedly connected to the top surface of the base plate 101, a drive motor 103 fixedly connected to one side of the bottom surface of the inner cavity of the lifting groove 102, a partition 104 fixedly connected to the bottom of the inner cavity of the base plate 101, and a top plate 105 fixedly connected to the top surface of the base plate 101. One end of the output shaft of the drive motor 103 passes through the top surface of the partition 104 and is fixedly connected to a lead screw 106. One end of the lead screw 106 is rotatably connected to the bottom surface of the top plate 105. The partition 104 has a slide rod 107 fixedly connected to one side of its top surface. One end of the slide rod 107 is fixedly connected to the bottom surface of the top plate 105. A lifting block 108 is threadedly connected to the side of the lead screw 106. The lifting block 108 is slidably connected to the side of the slide rod 107. A roller 109 is fixedly connected to the bottom surface of the bottom plate 101. A screw 110 is threadedly connected to the inside of the top surface of the bottom plate 101. There are two screws 110, which are symmetrically distributed on both sides of the top surface of the bottom plate 101. One end of the screw 110 is fixedly connected to a turntable 111. The other end of the screw 110 passes through the bottom surface of the bottom plate 101 and is rotatably connected to a pressure plate 112. A rubber pad 113 is fixedly connected to the bottom surface of the pressure plate 112.

[0027] In this embodiment, when the position of the television body 3 needs to be moved, the base plate 101 is pushed to drive the roller 109 to rotate, moving the base plate 101 to a designated position. After the base plate 101 moves to the designated position, the turntable 111 is rotated to drive the screw 110 to rotate. The screw 110 is connected to the base plate 101, and one end of the screw 110 drives the pressure plate 112 to move downward and stick to the ground to restrict the movement of the base plate 101. The rubber pad 113 can increase the friction between the pressure plate 112 and the ground, improving the stability of the pressure plate 112 in restricting the movement of the base plate 101. When the height of the television body 3 needs to be adjusted, the drive is activated. Motor 103 drives lead screw 106 to rotate, and lead screw 106 rotates to drive lifting block 108 to rise and fall. Slide rod 107 is connected to lifting block 108 to support lifting block 108 and improve the lifting stability of lifting block 108. When lifting block 108 rises and falls, it drives the TV body 3 to rise and fall through the fixing device to adjust the height of TV body 3. When TV body 3 reaches the appropriate height, drive motor 103 is turned off to stop lead screw 106 from rotating. Lead screw 106 is connected to lifting block 108 to fix the height of lifting block 108. Lifting block 108 fixes the height of TV body 3 through fixing device.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a connecting plate 114 is fixedly connected to the side of the lifting block 108 by a nut, a rotating shaft 115 is fixedly connected to the top surface of the connecting plate 114, a stud 116 is fixedly connected to the top surface of the connecting plate 114, a rotating block 117 is rotatably connected to the side of the rotating shaft 115, an arc-shaped groove 118 is provided on the top surface of the rotating block 117, the stud 116 is movably connected inside the arc-shaped groove 118, a limit block 119 is threadedly connected to one end of the stud 116, and a fixing plate 120 is fixedly connected to one end of the rotating block 117.

[0030] In this embodiment, when the rotation angle of the television body 3 needs to be adjusted, rotating the television body 3 causes the support plate 201 to rotate. The support plate 201 is connected to the fixing plate 120, causing the fixing plate 120 to rotate. The fixing plate 120 causes the rotating block 117 to rotate along the rotating shaft 115. When the television body 3 rotates to the specified angle, the rotation of the television body 3 stops and the limiting block 119 is rotated. The limiting block 119 moves downward along the stud 116 and sticks to the rotating block 117 to restrict the rotation of the rotating block 117, thereby fixing the rotation angle of the television body 3.

[0031] Example 3

[0032] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 2 includes a support plate 201, which is fixedly connected to the fixing plate 120 by nuts. The support plate 201 has post holes 202 on both sides of its bottom surface and a threaded hole 203 in the center of its bottom surface. A limiting post 204 is slidably connected inside the post hole 202, and a limiting plate 205 is fixedly connected to one end of the limiting post 204. A fixing screw is threaded inside the threaded hole 203. The female nut 206 is movably connected to the limiting plate 205. A knob 207 is fixedly connected to one end of the fixed nut 206. Two through holes 208 are provided on the side of the support plate 201. A telescopic base rod 209 is fixedly connected inside the through hole 208. A telescopic rod 210 is slidably connected inside the telescopic base rod 209. A limiting nut 211 is threadedly connected to the side of one end of the telescopic base rod 209. A limiting plate 212 is fixedly connected to one end of the telescopic rod 210.

[0033] In this embodiment, rotating the knob 207 according to the size of the television body 3 drives the fixing nut 206 to rotate. The fixing nut 206 is connected to the threaded hole 203 and the limiting plate 205. When the fixing nut 206 rotates, it drives the limiting plate 205 to rise and fall, adjusting the height of the limiting plate 205. When the limiting plate 205 rises and falls, it drives the two limiting posts 204 to slide in the two post holes 202 respectively. The two limiting posts 204 are connected to the limiting plate 205 to restrict the movement direction of the limiting plate 205, improving the stability of the lifting and lowering of the limiting plate 205. After the limiting plate 205 reaches the appropriate height, the knob 207 is stopped. The fixing nut 206 stops rotating, thus fixing the height of the first limiting plate 205. The TV body 3 is placed on the first limiting plate 205, which supports the TV body 3. The two second limiting plates 212 are pushed to drive the telescopic rod 210 to slide in the telescopic base rod 209, so that the two second limiting plates 212 are attached to the side of the TV body 3. The limiting nut 211 is rotated to restrict the sliding of the telescopic rod 210 in the telescopic base rod 209. The two telescopic base rods 209 connect the telescopic rod 210 and the second limiting plate 212 to clamp and fix the two sides of the TV body 3, preventing the TV body 3 from falling off the fixing device.

[0034] The working principle of this adjustable TV stand will be explained in detail below.

[0035] like Figure 1-5As shown, by rotating the knob 207 according to the size of the TV body 3, the fixing nut 206 is rotated. When the fixing nut 206 rotates, it causes the limiting plate 205 to rise and fall, adjusting the height of the limiting plate 205. When the limiting plate 205 rises and falls, it causes the two limiting posts 204 to slide in the two post holes 202 respectively. The two limiting posts 204 are connected to the limiting plate 205 to restrict the movement direction of the limiting plate 205, improving the stability of the lifting and lowering of the limiting plate 205. After the limiting plate 205 reaches the appropriate height, the knob 207 is stopped to fix the height of the limiting plate 205, and the TV body 3 is placed on the limiting plate 205. Pushing the two limiting plates 212 causes the telescopic rod 210 to slide within the telescopic base rod 209, so that the two limiting plates 212 adhere to the sides of the television body 3. Rotating the limiting nut 211 restricts the sliding of the telescopic rod 210 within the telescopic base rod 209. The two telescopic base rods 209 connect the telescopic rod 210 and the limiting plates 212 to clamp and fix both sides of the television body 3. When the position of the television body 3 needs to be moved, pushing the base plate 101 causes the roller 109 to rotate, moving the base plate 101 to the designated position. After the base plate 101 moves to the designated position, rotating the turntable 111 causes the screw 110 to rotate, and one end of the screw 110 drives the pressure... The pressure plate 112 moves downward and presses against the ground to restrict the movement of the base plate 101. The rubber pad 113 increases the friction between the pressure plate 112 and the ground, improving the stability of the pressure plate 112 in restricting the movement of the base plate 101. When the height of the TV body 3 needs to be adjusted, the drive motor 103 is started to drive the lead screw 106 to rotate. The rotation of the lead screw 106 drives the lifting block 108 to rise and fall. The slide rod 107 is connected to the lifting block 108 to support the lifting block 108 and improve the lifting stability of the lifting block 108. When the lifting block 108 rises and falls, it drives the TV body 3 to rise and fall through the fixing device to adjust the height of the TV body 3. When the TV body 3 reaches the set position... After reaching the appropriate height, the drive motor 103 is turned off to stop the lead screw 106 from rotating. The lead screw 106 fixes the height of the TV body 3 through the lifting block 108 and the fixing device. When it is necessary to adjust the rotation angle of the TV body 3, the TV body 3 is rotated to drive the support plate 201 to rotate. The support plate 201 drives the fixing plate 120 and the rotating block 117 to rotate along the rotating shaft 115. When the TV body 3 rotates to the specified angle, the TV body 3 is stopped from rotating and the limiting block 119 is rotated. The limiting block 119 moves downward along the stud 116 and sticks to the rotating block 117 to limit the rotation of the rotating block 117, thereby fixing the rotation angle of the TV body 3.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
