Technical Field
[0001] The present invention relates to the technical field of entertainment equipment, and particularly to a self-service karaoke machine. Background Art
[0002] With the development of society, singing has increasingly become the preferred form of entertainment for people. Singing requires karaoke equipment. Existing karaoke equipment generally includes three parts: video playback equipment, a song selection device, and audio equipment, which are all arranged and used indoors, cannot be moved as a whole, and the cost is relatively high. Moreover, this traditional equipment cannot be used in outdoor or open space occasions such as shopping malls, supermarkets, and cinemas.
[0003] In the Chinese invention patent with the publication number CN216211330U, a self-service karaoke machine is disclosed. By setting an electric telescopic rod A, the sound can be emitted by the up and down movement of the speaker to change the sound effect to meet people's needs. By setting a motor A and a motor B, the video playback screen can be deflected up and down and left and right according to the best viewing angle required by people to meet the needs. By setting a motor C, an electric telescopic rod B19, and an electric telescopic rod C21, the song selection touch screen 20 can be used more conveniently.
[0004] Regarding the above related technologies, the inventor believes that the following defects exist:
[0005] When the device is actually used, since the operation screen is exposed, it may get dusty or be collided when not in use, affecting the normal use of the screen. At the same time, the song selection device is also exposed on the outside. It is necessary to protect and isolate the screen and the song selection device when not in use. At the same time, the device needs to be moved outdoors and then fixed after reaching the working position, making the movement and limitation of the device rather troublesome. For this reason, we propose a self-service karaoke machine. Summary of the Invention
[0006] To solve the above-mentioned technical problems, the present invention provides a self-service karaoke machine.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0020] 1. By setting the limit component in the present invention, the bidirectional screw is rotated, so that the two threaded seats move in opposite directions. Under the action of the two connecting rods, the fixed seat drives the long board to move downward, so that the two lifting plates move downward along the lifting grooves under the action of the guide rods, so that the surface of the moving wheels abuts against the ground and the support legs are separated from the ground. At this time, the device is pushed to move. After reaching the working location, the bidirectional screw is rotated in the reverse direction, so that the bottom of the support legs abuts against the ground and the surface of the moving wheels is separated from the ground, enabling the device to work stably and facilitating the movement and fixation of the device.
[0021] 2. By setting the adjustment component in the present invention, after the device moves to the working location, the protective cover is opened, and then, as needed, the threaded rod is rotated, so that the moving seat moves along the installation groove. Under the action of the connecting rod, the installation frame deflects with the rotation axis as the starting point, so that the installation frame drives the display screen to deflect at an angle, enabling the device to adapt to different angle requirements and improving the applicable range of the device.
[0022] 3. By setting the display screen in the present invention, when it is necessary to order songs, first scan the QR code on the display screen to pay. After the payment is completed, the device releases the lock screen state of the display screen, and then the song ordering operation can be performed.
[0023] 4. By setting in the present invention, when it is necessary to perform the song ordering operation, first rotate the helical gear B, so that the helical gear A drives the bidirectional lead screw to rotate. The two threaded barrels move in opposite directions under the action of the blocks, so that the threaded barrels are separated from the sockets. Then, the fixed block is pulled outwards, so that the limit plate drives the control panel to be pulled out, and then the song ordering operation is performed through the control panel. After the song ordering work is completed, the limit plate is pushed back, reducing the situation of collision caused by the control panel protruding during singing and improving the safety of the device.
[0024] 5. By providing a storage slot, during the use of the device, some items needed for singing can be placed inside the storage slot, and then some items in the storage slot can be taken out after reaching the working position, which facilitates the storage of items. Limited rings are provided on both sides of the box body for placing microphones, which enables the direct use and placement of microphones during the use of the device, making the use of the device more convenient and fast.
[0025] 6. By providing a protective cover and a fixing block, after the device finishes working, the control panel is pushed into the inside of the sliding groove, and then the helical gear B is rotated in the reverse direction, so that the threaded barrel is inserted into the socket again to complete the limiting and fixing of the limiting plate, avoiding the situation of the limiting plate sliding out. Then the threaded rod is rotated in the reverse direction, so that the moving seat drives the display screen to deflect through the connecting rod, and the display screen deflects towards the top of the box body. After the display screen rotates to the lowest position, the protective cover is covered again to ensure that the display screen can be folded and stored when not working, reducing the collision caused by the contact between the display screen and the outside world and improving the safety of the display screen.
