Description

Technical Field

[0001] The utility model belongs to the field of household appliances, in particular to a lifting socket. Background Art

[0002] Power sockets are widely used. Their function is to provide power to electrical equipment. There are many types of power sockets, such as floor sockets, desktop sockets, wall sockets, etc.

[0003] After searching, a Chinese patent discloses a lifting socket (authorization announcement number CN 219626978U). The patent technology includes a shell, a plug-in plate is slidably arranged inside the shell, a slide plate is arranged on one side of the plug-in plate, the slide plate slides inside a slide groove opened on one side of the shell, a positioning assembly is arranged on the outside of the shell, the lower end of the positioning assembly is connected to the anti-fall assembly arranged on the lower side of the shell, the slide plate is slidably connected to the positioning assembly, when the plug-in plate is located inside the shell, the positioning assembly limits the slide plate, when the positioning assembly moves downward, not only the anti-fall assembly is pushed downward to extend the anti-fall assembly out of the shell, but also the slide plate loses its force to make the plug-in plate slide out of the shell. The utility model, through the connection between the screw and the lower pressing block, when the screw slides downward with the lower pressing block, the lower pressing block squeezes the extension plate, so that the extension plate slides out of the slideway, thereby increasing the contact area between the overall device and the desktop, increasing the friction coefficient, and improving the stability of the device when in use.

[0004] The device can improve the stability of the overall device by providing an extension plate, and the plug plate can be stored inside the shell for waterproofing when not in use. However, although the plug plate in the device fits with the inner wall of the shell after being stored inside the shell, there is still a tiny gap, and after repeated use for a long time, the gap will inevitably increase, thereby reducing the waterproof effect. When the device is used on a desktop, if there is spilled domestic water on the desktop, it will penetrate into the device through the gap between the plug plate and the shell, causing moisture, thereby reducing the service life. In addition, the plug plate in the device is relatively fixed when in use and cannot be rotated to other angles, resulting in a reduced user experience. Utility Model Content

[0023] Specifically, the transmission assembly includes a screw 8, which is rotatably connected to one side of the inner wall of the shell 1, and the lifting block 2 is threadedly connected to the outside of the screw 8. The bottom of one side of the inner wall of the shell 1 is fixedly connected to a motor 9, and the output end of the motor 9 is fixedly connected to the screw 8. The side of the inner wall of the shell 1 away from the screw 8 is fixedly connected to a limit rod 10, and the lifting block 2 is slidably connected to the outside of the limit rod 10. The linkage assembly includes a worm 11, which is fixedly connected to the top of the screw 8, and a worm wheel 12 is rotatably connected to the side of the inner wall of the shell 1 close to the worm 11, and the worm wheel 12 is meshed with the worm 11. The outside of the rotating shaft 5 is fixedly connected to a first pulley 13, and the outer side of the worm wheel 12 is fixedly connected to a second pulley 14. The first pulley 13 and the second pulley 14 are connected and connected through a transmission belt 15 that runs through the inner wall of the shell 1.

[0024] Through the above technical solution, the device can be installed under the desktop by the shell 1, so that it can be used on the desktop of each room in the family. When the plug board 3 is not in use, the plug board 3 is stored in the shell 1. The protection of the cover plate 6 and the sealing strip 7 can effectively prevent external water droplets or moisture from entering the shell 1, providing moisture-proof protection for the plug board 3. When the plug board 3 needs to be used, the motor 9 is started, and the output end of the motor 9 drives the lead screw 8 to rotate. The lead screw 8 then drives the lifting block 2 to rise under the limit of the limit rod 10 through the threaded connection relationship, thereby driving the plug board 3 to rise, and the lead screw 8 can drive the top The worm 11 at the bottom rotates, so that the worm 11 drives the worm wheel 12 and the second pulley 14 to rotate through the meshing relationship, and the second pulley 14 then drives the first pulley 13 and the rotating shaft 5 to rotate through the transmission belt 15, and the rotating shaft 5 can drive the external cover plate 6 to rotate. When the cover plate 6 is rotated and opened, the plug plate 3 is completely raised to the outside of the shell 1 at the same time, and can be connected to the external electrical equipment for use. Similarly, when the plug plate 3 is not needed, the plug plate 3 is controlled to descend to the inside of the shell 1 again, and the cover plate 6 can be closed through the linkage component, so as to achieve the purpose of protecting the plug plate 3. When the plug plate 3 is to be rotated for use, the plug plate 3 is manually rotated, and the limit plate 4 at the bottom of the plug plate 3 pushes the limit block 17 into the inside of the slide slot 16 through the slot 19, and at the same time squeezes the spring 18 to deform the spring 18, and then the plug plate 3 is continued to be rotated. When the limit plate 4 is away from the limit block 17, the limit block 17 can rebound under the rebound force of the spring 18, until the next limit plate 4 rotates to the limit block 17, and then it is pushed into the inside of the slide slot 16 again, and then when the slot 19 at the bottom of the corresponding limit plate 4 moves to just above the limit block 17, the limit The card block 17 can be re-entered into the corresponding card slot 19 and limit the plug board 3. After the plug board 3 is used and lowered to the inside of the shell 1, the device can drive the cover plate 6 to protect the shell 1, effectively preventing external water on the desktop from penetrating into the device through the gap between the shell 1 and the plug board 3, causing the device to get damp and reduce its service life, or even causing electrical safety accidents, thereby improving the safety of the device. The rotatable plug board 3 can be easily rotated to different angles for use by cooperating with the limit card block 17, thereby improving the use experience.

[0025] Specifically, both sides of the lifting block 2 are symmetrically provided with slide grooves 16, and a limit block 17 is slidably connected to the upper part of the slide groove 16. A spring 18 is provided inside the slide groove 16 and at the bottom of the limit block 17. The bottom of the limit plate 4 is provided with a slot 19. The top of the limit block 17 extends to the top of the lifting block 2 and cooperates with the slot 19. The top of the limit block 17 is a hemispherical structure, and two groups of sockets of different specifications are provided on one side of the outside of the plug plate 3.

[0026] Through the above technical solution, the rotatable plug board 3 cooperates with the limiting block 17 to facilitate the plug board 3 to be rotated to different angles for use, thereby improving the use experience.

[0027] Specifically, a sealing groove matched with the sealing strip 7 is formed at the bottom of the cover plate 6 . The sealing strip 7 is made of a silicone material. A sealing pad is fixedly connected to the outside of the lifting block 2 .

[0028] Through the above technical solution, the sealing performance of the device after the plug board 3 is raised is further improved by the provided sealing pad.

[0029] When in use, the device can be installed under the desktop by the shell 1, so that it can be used on the desktop of each room in the family. When the plug board 3 is not in use, the plug board 3 is stored in the shell 1. The protection of the cover plate 6 and the sealing strip 7 can effectively prevent external water droplets or moisture from entering the shell 1, providing moisture-proof protection for the plug board 3. When the plug board 3 needs to be used, the motor 9 is started, and the output end of the motor 9 drives the lead screw 8 to rotate. The lead screw 8 then drives the lifting block 2 to rise under the limit of the limit rod 10 through the threaded connection relationship, thereby driving the plug board 3 to rise. At the same time, the lead screw 8 can drive the worm 11 at the top to rotate, so that the worm 11 drives the lifting block 2 to rise under the limit of the limit rod 10 through the meshing relationship. The movable worm gear 12 and the second pulley 14 rotate, and the second pulley 14 then drives the first pulley 13 and the rotating shaft 5 to rotate through the transmission belt 15, and the rotating shaft 5 can drive the external cover plate 6 to rotate. When the cover plate 6 is rotated and opened, the plug plate 3 is completely raised to the outside of the shell 1 at the same time, and the external electrical equipment can be connected for use. Similarly, when the plug plate 3 is not needed, the plug plate 3 is controlled to be lowered to the inside of the shell 1 again, and the cover plate 6 can be closed by the linkage component, so as to achieve the purpose of protecting the plug plate 3. When the angle of the plug plate 3 needs to be rotated for use, the plug plate 3 is manually rotated, and the limit plate 4 at the bottom of the plug plate 3 is moved through the slot 19 The limit block 17 is pushed toward the inside of the slide groove 16, squeezing the spring 18 at the same time, causing the spring 18 to deform, and then the plug plate 3 continues to rotate. When the limit plate 4 is away from the limit block 17, the limit block 17 can rebound under the rebound force of the spring 18 until the next limit plate 4 rotates to the limit block 17 and pushes it into the inside of the slide groove 16 again. Then, when the corresponding card slot 19 at the bottom of the limit plate 4 moves to just above the limit block 17, the limit block 17 can rebound into the corresponding card slot 19 again and limit the plug plate 3. After the plug plate 3 is used and descends to the inside of the shell 1, the device can drive the cover at the same time The plate 6 protects the shell 1, and effectively prevents external water on the desktop from penetrating into the device through the gap between the shell 1 and the plug-in board 3, causing the device to get damp and reduce its service life, or even causing electrical safety accidents, thereby improving the safety of the device. The rotatable plug-in board 3 cooperates with the limiting block 17 to facilitate the plug-in board 3 to be rotated to different angles for use, thereby improving the user experience. The rotatable plug-in board 3 cooperates with the limiting block 17 to facilitate the plug-in board 3 to be rotated to different angles for use, thereby improving the user experience.
