Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a hidden wall socket. Background Art

[0002] A hidden socket is a socket that can be hidden in the wall or on the ground. Its appearance is integrated with the surrounding walls or ground, which has the function of beautifying and decorating. At the same time, it can also meet the needs of electrical functions without affecting the overall decoration effect.

[0003] Patent application number: 202223010074.2 proposes a rotatable hidden wall socket, including a shell, a socket base, and a cover plate. The socket base is placed in the shell and movably assembled with the shell. The socket base is provided with a clamping part, and a gap is provided between the two sides of the clamping part and the socket base. The clamping part is provided with a protrusion, and the side wall of the shell is provided with a plurality of adjustment holes that cooperate with the protrusion. The socket base is rotatably adjusted in multiple gears with the protrusion as the axis. When the socket base is connected to a straight plug, the cover plate can also be closed, the socket base is rotated to a suitable gear, the plug is tilted, and the power cord is placed in the notch groove to cover the cover plate to cover the plug, making the wall more beautiful and also playing a role of safety protection.

[0004] This device also has some shortcomings. For example, when unplugging the plug, the large plug-in and unplugging force can easily cause the protrusion on the socket base to separate from the adjustment hole, causing the socket base to rotate or slide inside the shell, which may cause the plug to fail to be fully inserted into the socket, affecting the normal operation of the appliance. Summary of the invention

[0005] The purpose of the utility model is to provide a hidden wall socket to solve the problems raised in the above background technology.

[0024] When the device is used, the cover plate 3 is first opened, and then the knob 7 is turned to drive the screw rod 6 to rotate. The screw rod 6 drives the threaded block 8 to move on itself, and drives the socket 4 to move inside the housing 1. The socket 4 is adjusted to a suitable position according to the plug to be used. The screw rod 6 and the threaded block 8 are conveniently used to limit the socket 4 to prevent the socket from moving when the plug is plugged in and out, and to improve the connection effect between the plug and the socket 4. Then, the plug is inserted into the socket 4, and the cover plate 3 is closed. The cover plate 3 is buckled on the mounting plate 2 by the snap lock 21. The upper limit support component of the cover plate 3 will press the plug to improve the connection effect between the plug and the socket 4, and prevent the plug from being poorly connected with the socket 4, which affects the operation of the electrical appliance.

[0025] Among them, support plates are fixedly installed inside the adjustment groove 5, and the screw rod 6 is rotatably connected to one of the support plates to facilitate the screw rod 6 to provide auxiliary support and ensure the normal operation of the screw rod 6. One end of the sliding rod 10 is fixedly connected to another support plate to provide fixed support for the sliding rod 10 and prevent the slider 9 from falling off the sliding rod 10.

[0026] The limiting support assembly includes a connecting guide rod 11 inserted on the cover plate 3, and a pressing plate 12 is fixedly installed on one end of the connecting guide rod 11 facing the socket 4. A spring 16 is sleeved on the outer surface of the connecting guide rod 11, one end of the spring 16 is connected to the inner wall of the cover plate 3, and the other end of the spring 16 is connected to the surface of the pressing plate 12.

[0028] The other ends of the connecting guide rods 11 extend to the outside of the cover plate 3 , and the other ends of the connecting guide rods 11 are fixedly mounted with a limit plate 15 to prevent the connecting guide rods 11 from sliding off the cover plate 3 and affecting the normal operation of the device.

[0029] An extension plate 13 is fixedly mounted on the upper surface of the pressing plate 12 , and a plurality of elastic pads 14 are fixedly mounted on the surfaces of the pressing plate 12 and the extension plate 13 facing the socket 4 , and the elastic pads 14 correspond to the sockets on the socket 4 .

[0030] When the appliance is finished using, the knob 7 can be turned to move the socket 4 to the front of the housing 1, and then the cover plate 3 is covered on the mounting plate 2. The limit support assembly contacts the surface of the socket 4, and the elastic pad 14 blocks the socket on the socket 4 to prevent dust from accumulating in the socket when the socket is not in use, thereby affecting the next use of the socket 4.

[0031] Furthermore, two wire leakage grooves 17 are provided at the bottom end of the cover plate 3, and a telescopic groove 19 is provided on the inner wall of the wire leakage groove 17 away from the socket 4. A spring 20 is fixedly connected to the inside of the telescopic groove 19, and a baffle 18 is fixedly connected to one end of the spring 20. The baffle 18 is slidably arranged inside the telescopic groove 19, and one end of the baffle 18 extends to the inside of the wire leakage groove 17 to block the wire leakage groove 17.

[0032] The power cord on the plug extends out of the device through the leakage wire groove 17. Two auxiliary leakage wire grooves are provided on the surface of the mounting plate 2. The positions of the auxiliary leakage wire grooves correspond to the leakage wire grooves. The baffle 18 inside the leakage wire groove 17 will be affected by the elastic force of the spring 20 and move to one side of the mounting plate 2 to squeeze and fix the power cord, reduce the shaking of the power cord inside the auxiliary leakage wire groove, and increase the service life of the power cord. When the appliance is finished using, the spring 20 will push the baffle 18 to block the auxiliary leakage wire groove through its own elastic force to prevent dust from entering the cover plate 3 and affecting the operation of the socket 4.

[0033] Furthermore, limiting grooves are provided on the inner walls on both sides of the telescopic groove 19, and limiting sliders are fixedly installed on the two side surfaces of the baffle 18. The limiting sliders are slidably connected to the limiting grooves to limit the movement of the baffle 18 and prevent the baffle 18 from escaping from the telescopic groove 19 and affecting the normal operation of the device.

[0034] Working principle: When using the hidden wall socket, first open the cover 3, then turn the knob 7 to drive the screw rod 6 to rotate, and the screw rod 6 drives the threaded block 8 to move on itself, driving the socket 4 to move inside the housing 1. After adjusting the socket 4 to a suitable position according to the plug to be used, insert the plug into the socket 4, and then close the cover 3, and buckle the cover 3 on the mounting plate 2 through the snap lock 21.
