Background technique

Television sets, which transmit live visual images instantly by means of electricity. Similar to movies, television uses the visual residual effect of the human eye to display frame-by-frame still images, forming visually moving images. The sending end of the TV system converts each tiny part of the scene into electrical signals according to brightness and chromaticity, and then transmits them sequentially. At the receiving end, the brightness and chromaticity of each tiny part are displayed according to the corresponding geometric position to reproduce the entire original image. A device for receiving TV broadcasts, consisting of complex electronic circuits, speakers, fluorescent screens, etc. Its function is to receive the full TV signal transmitted by the TV station through the antenna, and then separate the video signal and audio signal through the electronic circuit, and restore the image and sound through the fluorescent screen and the speaker respectively.

Flat-panel TVs are usually installed on the walls of buildings by TV brackets, but once the existing TV brackets fix the TV, the height of the TV is completely fixed and cannot be adjusted. This installation method is very inconvenient.

In order to achieve the above object, the utility model provides the following technical solutions:

A liftable television stand, comprising two supporting columns, a slider, a mounting rod, three fixing plates and a motor, the three fixing plates are arranged side by side in parallel, and several threaded holes are uniformly arranged on the fixing plates, and the fixing plates The left and right sides of the support column are symmetrically provided with support columns, the positive end surface of the support column is provided with a track groove, and a lead screw is arranged in the track groove, the lead screw is connected to the support column through a bearing, and one end of the lead screw passes through the top wall of the support column and Fixedly connected to the motor shaft of the motor, the motor is fixed on the top of the support column, a control switch is provided on the top of one motor, the control switch is electrically connected to the two motors respectively, and the two motors are respectively connected to the external power supply, and the lead screw is sleeved There is a slider matching the track groove, the threaded connection between the screw and the slider, and the sliding connection between the slider and the track groove. There are several installation rods fixedly connected between the two sliders. Mounting holes.

As a further technical solution of the utility model, the track groove is a T-shaped groove.

As a further technical solution of the utility model, 2 to 3 installation rods are fixedly connected between the two sliders.

As a further technical solution of the utility model, all the mounting bars are arranged side by side in parallel.

As a further technical solution of the utility model, the motor is a bidirectional motor.

Compared with the prior art, the utility model drives the lead screw to rotate clockwise or counterclockwise through the forward and reverse rotation of the motor, and then drives the slider to move upward or downward, thereby realizing the rising and falling adjustment of the TV set. It is convenient for home use, simple in structure and convenient in adjustment.

detailed description

The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

Please refer to Figures 1 to 2, a liftable TV bracket, including two support columns 1, a slider 6, a mounting rod 7, three fixing plates 9 and a motor 11, and the three fixing plates 9 are parallel to each other Arranged, the fixed plate 9 is uniformly provided with some threaded holes 10, the left and right sides of the fixed plate 9 are symmetrically provided with support columns 1, and the positive end surface of the support column 1 is provided with a track groove 2, and the track groove 2 is T The track groove 2 is provided with a lead screw 3, the lead screw 3 is rotationally connected with the support column 1 through the bearing 4, and one end of the lead screw 3 passes through the top wall of the support column 1 and is fixedly connected to the motor shaft of the motor 11. Above, the motor 11 is fixed on the top of the supporting column 1, and the top of one motor 11 is provided with a control switch 12, and the control switch 12 is electrically connected with two motors 11 respectively, and the two motors 11 are respectively connected with an external power source, so The lead screw 3 is sleeved with a slider 6 that matches the track groove 2, and the lead screw 3 and the slider 6 are threaded, and the slider 6 and the track groove 2 are slidably connected. Several installation rods 7 are fixedly connected between the blocks 6, and all the installation rods 7 are arranged side by side in parallel, and the installation rods 7 are provided with installation holes 8.

The motor 11 is a bidirectional motor.

When the utility model is used, the TV set is directly installed on the installation rod 7, and the two supporting columns 1 are fixed on the wall through the fixing plate 9, and the forward rotation of the starting motor 11 drives the screw rod 3 to rotate clockwise, so that the sliding The block 6 moves up under the drive of the lead screw 3, thereby driving the TV to rise, the starter motor 11 reversely rotates, and then drives the lead screw 3 to rotate counterclockwise, so that the slider 6 moves down under the drive of the lead screw 3, Then the TV is driven down, so as to realize the height adjustment of the TV.

The preferred implementation of this patent has been described in detail above, but this patent is not limited to the above-mentioned implementation. Within the scope of knowledge possessed by those of ordinary skill in the art, various implementations can also be made without departing from the purpose of this patent. kind of change.
