[0022] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Reference Figures 1-11 A detachable sliding device for a wall-mounted karaoke machine includes a first mounting plate 3 disposed inside a wall 1 and a second mounting plate 4 disposed outside the wall 1. The first mounting plate 3 and the second mounting plate 4 are connected by a telescopic mechanism. A movable seat 23 is provided on the outer wall of the second mounting plate 4 away from the first mounting plate 3. The movable seat 23 is fitted with a karaoke machine body 5 through a quick-connect mechanism. Both outer walls of the second mounting plate 4 are provided with auxiliary installation mechanisms to assist in the quick installation of the karaoke machine body 5 inside the movable seat 23.

[0024] As a technical optimization of the present invention, a groove 2 is provided inside the wall 1, and multiple connecting sleeves are pre-set on one side of the inner wall of the groove 2. The first mounting plate 3 is threadedly connected to the corresponding connecting sleeves by multiple bolts 7. Figure 2As shown, multiple holes are made on one side of the inner wall of the wall 1, and multiple connecting sleeves are glued to the corresponding holes with adhesive, so that the first mounting plate 3 can be threadedly connected to the corresponding connecting sleeves with multiple bolts 7, ensuring that the first mounting plate 3 is stably installed inside the groove 2.

[0025] As an optimized technical solution of the present invention, the telescopic mechanism includes a double-ended screw 14. A rectangular groove 8 is formed inside the first mounting plate 3. The double-ended screw 14 is rotatably installed inside the rectangular groove 8. Two moving blocks 15 are threadedly installed on the outer wall of the double-ended screw 14. A first rotating block 16 is rotatably installed at the end of each moving block 15 away from the double-ended screw 14. A first driving device is preset inside the first mounting plate 3. The output end of the first driving device is connected to one end of the double-ended screw 14, thereby driving the double-ended screw 14 to rotate inside the rectangular groove 8. As the double-ended screw 14 rotates, it can drive the two moving blocks 15 on its outer wall to move and adjust in a direction that is closer to or farther away from each other.

[0026] As a technical optimization of the present invention, two second rotating blocks 17 are rotatably mounted on the outer wall of the second mounting plate 4 near the first mounting plate 3. The two second rotating blocks 17 and their adjacent first rotating blocks 16 are connected and fixed by a first electric telescopic rod 9. When the two moving blocks 15 move toward each other, they can drive the two first rotating blocks 16 and the second rotating blocks 17 to rotate and adjust in the same direction, thereby pushing the second mounting plate 4 to move and adjust away from the first mounting plate 3. When the two first electric telescopic rods 9 rotate to a parallel state, the extension of the telescopic ends of the two first electric telescopic rods 9 can push the second mounting plate 4 to move and adjust further away. When the two moving blocks 15 move away from each other, they can drive the two first rotating blocks 16 and the second rotating blocks 17 to rotate and adjust in the same direction, thereby pulling the second mounting plate 4 to move and adjust closer to the first mounting plate 3.

[0027] As a technical optimization of the present invention, a first groove 10 is formed on the outer wall of the second mounting plate 4 away from the first mounting plate 3. A first slider 20 is installed inside the first groove 10. A fixed seat 12 is installed at the end of the first slider 20 away from the first groove 10. A third rotating block 21 is provided on the outer wall of the movable seat 23 near the second mounting plate 4. The third rotating block 21 is rotatably connected to the fixed seat 12. A drive motor 22 is provided on the outer wall of the fixed seat 12, with its output end connected to the rotating part of one end of the third rotating block 21. A first linear motor is preset inside the first groove 10. The first linear motor can drive the first slider 20 to move up and down inside the first groove 10, thereby driving the fixed seat 12, the third rotating block 21, and the movable seat 23 to move up and down on the front of the second mounting plate 4 for adjustment. The drive motor 22 can drive the third rotating block 21 and the fixed seat 12 to rotate for adjustment.

[0028] As a technical optimization of the present invention, the quick connection mechanism includes a connection groove 24 opened on the outer wall of the movable seat 23 away from the second mounting plate 4, and a connection block 18 adapted to the connection groove 24 is installed on the back of the karaoke machine body 5.

[0029] As a technical optimization of the present invention, two fixed frames 26 are installed on both outer walls of the movable seat 23. Sliding rods 27 are slidably installed inside the two fixed frames 26. Limiting blocks 25 are slidably installed on the movable seat 23 near the two fixed frames 26. The ends of the two sliding rods 27 that are close to each other are connected to their corresponding limiting blocks 25.

[0030] As a technical optimization of the present invention, springs 28 are fitted on the outer walls of both slide rods 27, and limiting grooves 19 adapted to the two limiting blocks 25 are opened on both sides of the outer walls of the connecting block 18. Since the two limiting blocks 25 have arc surfaces at their close ends, when the connecting block 18 on the back of the karaoke machine body 5 is placed inside the connecting groove 24, the karaoke machine body 5 is pushed inward, so that the connecting block 18 can automatically squeeze the arc surfaces of the two limiting blocks 25. After being squeezed, the two limiting blocks 25 move in opposite directions by means of the sliding of the corresponding slide rods 27 inside the fixing frame 26 and the elastic contraction of the springs 28, until the connecting block 18 is completely inside the connecting groove 24. Then, the two limiting blocks 25 are no longer squeezed and can be reset by means of the elasticity of the springs 28, which drives the limiting blocks 25 to slide back and be inserted into the corresponding limiting grooves 19. The connecting block 18 installed inside the connecting groove 24 is limited and fixed, thus completing the installation and fixing of the karaoke machine body 5.

[0031] As a technical optimization of the present invention, the auxiliary installation mechanism includes second sliding grooves 11 opened on the outer walls of both sides of the second mounting plate 4. Second sliders 29 are installed inside each of the two second sliding grooves 11. Moving rods 13 are installed at the ends of the two second sliders 29 away from the second sliding grooves 11. Third sliding grooves 30 are opened at the top of each of the two moving rods 13. Third sliders 34 are installed inside each of the two third sliding grooves 30. Mounting blocks 31 are installed at the top of each of the two third sliders 34. Second linear motors are pre-installed inside each of the two second sliding grooves 11. These motors can drive the two second sliders 29 to move up and down within their respective second sliding grooves 11, thereby causing the two moving rods 13 to move up and down on both sides of the second mounting plate 4 for adjustment. Similarly, third linear motors are pre-installed inside each of the two third sliding grooves 30. These motors can drive the two third sliders 34 to move back and forth within their respective third sliding grooves 30, thereby causing the two mounting blocks 31 to move back and forth at the top of the moving rods 13 for adjustment.

[0032] As a technical optimization of the present invention, a second electric telescopic rod 32 is rotatably mounted on the front of each of the two mounting blocks 31. A mounting base 33 is mounted on the telescopic end of each of the two second electric telescopic rods 32. A rotating rod 6 is rotatably mounted inside each of the two mounting bases 33. A slot 35 adapted to the thickness of the karaoke machine body 5 is opened on the outer wall of the side of the two rotating rods 6 that is close to each other. A fourth sliding groove 36 is opened on the inner wall of the side of the two slots 35. A fourth slider 37 is installed inside the two fourth sliding grooves 36. A push plate 38 is installed on the end of the two fourth sliders 37 that is away from the fourth sliding groove 36. A cleaning pad 39 is installed on the outer wall of the side of the two rotating rods 6 that is close to the second mounting plate 4. A second drive device is pre-installed inside each of the two mounting blocks 31. The output ends of the two second drive devices are connected to their corresponding second electric telescopic rods 32, thereby driving the two second electric telescopic rods 32, the mounting base 33, and the rotating rod 6 to rotate and adjust together. A third drive device is pre-installed on one outer wall of each of the two mounting bases 33. The output ends of the two third drive devices are respectively connected to one rotating part of their corresponding rotating rod 6, thereby driving the two rotating rods 6 to rotate and adjust inside the corresponding mounting base 33. A fourth linear motor is pre-installed inside each of the two fourth slide grooves 36. The two fourth linear motors can drive the two fourth sliders 37 to move up and down inside the corresponding fourth slide grooves 36, thereby driving the two push plates 38 to move up and down and adjust together on the side where the two rotating rods 6 are close to each other.

[0033] In this invention, when the user uses the device, firstly, a groove 2 is made on the wall 1, and holes are made at the four corners of the groove 2. Multiple connecting sleeves are glued to the corresponding holes with adhesive. Then, the first mounting plate 3 can be threadedly connected to the corresponding connecting sleeves with multiple bolts 7. Then, the second mounting plate 4 and other components are installed on the front of the wall 1, waiting for the subsequent installation and fixing of the karaoke machine body 5.

[0034] like Figure 9 As shown, when installing the karaoke machine body 5 inside the movable base 23, first control the two rotating rods 6 to rotate downwards to a horizontal state inside the corresponding mounting base 33. Then, based on the length of the karaoke machine body 5, control the two third sliders 34 to move the mounting block 31 and rotating rods 6 towards each other within the corresponding third sliding groove 30, ensuring that the distance between the two rotating rods 6 matches the length of the karaoke machine body 5. Then, the screen of the karaoke machine body 5 can be placed downwards and inserted into the two slots 35 until the horizontally placed karaoke machine body 5, near the second mounting plate 4, abuts against the two push plates 38. Finally, control the two rotating rods 6 to rotate upwards together to a vertical state, thus synchronously rotating the karaoke machine body 5 as shown. Figure 10 In the vertical position shown, the bottom of the karaoke machine body 5, which is in a vertical position, is supported and lifted by two push plates 38. It can move up and down in the corresponding fourth slide groove 36 with the help of two fourth sliders 37, thereby driving the height of the karaoke machine body 5 at the top of the two push plates 38 to move and adjust, ensuring that the connecting block 18 on the back of the karaoke machine body 5 moves to a position that matches the connecting groove 24. Next, by slowly retracting the extension ends of the two second electric telescopic rods 32, the connecting block 18 can be slowly inserted into the connecting groove 24. The connecting block 18 can automatically press the arc surfaces of the two limiting blocks 25. After being pressed, the two limiting blocks 25 move in opposite directions by sliding the corresponding slide rod 27 inside the fixing frame 26 and elastically contracting the spring 28 until the connecting block 18 is completely inside the connecting groove 24. Then, the two limiting blocks 25 are no longer pressed and can be elastically reset by the spring 28, causing the limiting blocks 25 to slide back and be inserted into the corresponding limiting groove 19. The connecting block 18 installed inside the connecting groove 24 is fixed and positioned, thus completing the installation and fixing of the karaoke machine body 5. The entire installation of the karaoke machine body 5 is an automated operation, eliminating the need for manual calibration of the installation position of the karaoke machine body 5, which takes a long time and improves the installation efficiency of the karaoke machine body 5.

[0035] When it is necessary to disassemble the karaoke machine body 5, the two rotating rods 6 can be controlled to rotate upwards together as follows. Figure 10In the vertical position shown, the slots 35 on the side of the two vertical rotating rods 6 that are close to each other are engaged with the two ends of the karaoke machine body 5. The tops of the two push plates 38 abut against the bottom of the karaoke machine body 5. Then, the two sliding rods 27 can be manually pulled to move away from each other, which will cause the two limiting blocks 25 to move out of the corresponding limiting grooves 19. At this time, the two limiting blocks 25 release the limiting fixation of the connecting block 18. With the extension of the telescopic ends of the two second electric telescopic rods 32, the two rotating rods 6 and the karaoke machine body 5 move together away from the second mounting plate 4, which can complete the quick disassembly of the karaoke machine body 5 and improve the disassembly efficiency of the karaoke machine body 5.

[0036] When the karaoke machine body 5 is installed inside the movable base 23, the double-headed screw 14 can be controlled to rotate forward and backward inside the rectangular slot 8, driving the two movable blocks 15 to move towards or away from each other. When the two movable blocks 15 move towards each other, they push the second mounting plate 4 to move away from the first mounting plate 3. When the two first electric telescopic rods 9 rotate to a parallel state, the extension of the telescopic ends of the two first electric telescopic rods 9 can push the second mounting plate 4 to move further away, thereby driving the karaoke machine body 5 to move away from the wall 1. When the two movable blocks 15 move away from each other, they can pull the second mounting plate 4 to move closer to the wall 1, making it convenient to adjust the lateral position of the karaoke machine body 5 indoors.

[0037] When the height of the karaoke machine body 5 needs to be adjusted, the first slider 20 can be moved up and down inside the first slide groove 10, which can drive the fixed base 12, the third rotating block 21, the movable base 23 and the karaoke machine body 5 installed inside the movable base 23 to move up and down together, making it convenient for people of different heights to use the karaoke machine body 5.

[0038] At the same time, since the drive motor 22 can drive the third rotating block 21 to rotate and adjust inside the fixed base 12, it will also drive the moving base 23 and the karaoke machine body 5 to rotate and adjust their angles. Users do not need to look down or up too much to view the screen content of the karaoke machine body 5. Furthermore, when the karaoke machine body 5 malfunctions and needs to be repaired, adjusting it to a suitable angle will also make it easier for maintenance personnel to disassemble and install related components.

[0039] When dust or other impurities are found on the screen surface of the karaoke machine body 5, affecting the user's viewing and use of the screen, such as... Figure 1As shown, the two rotating rods 6 can be controlled to rotate upward together in the corresponding mounting base 33 to a vertical state, and the telescopic ends of the two second electric telescopic rods 32 can be controlled to extend and retract together, pushing the two vertical rotating rods 6 to a position flush with the screen of the karaoke machine body 5. At this time, the cleaning pads 39 installed on one side of the outer wall of the two rotating rods 6 are flush with and abut against the screen of the karaoke machine body 5. The two second electric telescopic rods 32 are controlled to drive the corresponding rotating rods 6 downward in sequence, so that the two cleaning pads 39 can automatically clean the dust and other impurities on the screen of the karaoke machine body 5 in sequence, without the need for manual cleaning of the dust and other impurities on the screen of the karaoke machine body 5 with a rag, thus improving the efficiency of cleaning the screen of the karaoke machine body 5.

[0040] Since both rotating rods 6 are made of rubber, they can also be used as follows during the use of the karaoke machine body 5. Figure 10 As shown, the two rotating rods 6 are moved and adjusted to both ends of the karaoke machine body 5, and the two slots 35 are engaged with both ends of the karaoke machine body 5. At this time, the two rotating rods 6 made of rubber material are located at both ends of the karaoke machine body 5 and can be used as anti-collision measures to prevent children or people of short stature from colliding with the corners of both ends of the karaoke machine body 5, thereby improving the protection effect for users and the karaoke machine body 5.

[0041] Meanwhile, if it is not necessary to use two rotating rods 6 to protect both ends of the karaoke machine body 5, such as Figure 11 As shown, after the two rotating rods 6 are rotated upwards to a vertical position, the telescopic ends of the two second electric telescopic rods 32 are retracted to their shortest state, causing the two rotating rods 6 to move to the back of the karaoke machine body 5. Then, the two third sliders 34 are controlled to move towards each other inside the corresponding third slide grooves 30, thereby causing the two rotating rods 6 to block the ends of the slide rods 27 at both ends of the moving base 23. This prevents the user from pulling the two slide rods 27, which could cause the karaoke machine body 5 to fall downwards from the moving base 23 and break on the ground. This further improves the protection of the karaoke machine body 5 and ensures its safe use.
