Description

extendable wall socket

technical field

The invention relates to a socket, in particular to an extendable wall socket.

Background technique

At present, the wall sockets commonly used in daily life are directly fixed on the wall. Some electrical appliances cause a lot of inconvenience due to the insufficient length of the power cord when using them. For example, the sockets in university classrooms are generally located on the front wall of the classroom. There is a certain distance from the wall socket, and students often cannot obtain power supply because the computer power cord is not long enough when using the computer.

Contents of the invention

The purpose of the present invention is to provide a simple and convenient extendable wall socket, which solves the inconvenience caused by the insufficient length of electrical power cords.

An extendable wall socket of the present invention comprises an insulating shell, a socket, a plastic buckle, a key module, a microprocessor, a micro motor, a wire, and a connecting shaft. It is characterized in that the surface of the insulating shell has jacks, and there are plastic buckles on both sides of the insulating shell, and the jacks are connected to the grid circuit through wires on the back of the insulating shell, and the wires are wound on the connecting shaft Above, the connecting shaft is connected with the output rotating shaft of the micro motor, and when the micro motor drives the connecting shaft to rotate, the usable length of the wire wound on the connecting shaft will change. A microprocessor is fixed in the insulating housing, the key module is connected with the microprocessor, and the microprocessor is connected with the micro motor.

In the above solution, the microprocessor usually adopts MK60N512ZVLL10 chip.

The beneficial effects of the utility model are: the utility model utilizes the plastic buckles on both sides of the insulating shell to realize the fixing and separation of the socket and the wall, and inputs the button information into the microprocessor to change the control signal of the microprocessor to the micro motor , so that the micro motor rotates and drives the wire wound on the connecting shaft, thereby changing the available length of the wire, which is simple and convenient, solves the inconvenience caused by the limited length of the electrical power cord, and improves the use range of the socket.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing.

1 and 2, an extendable wall socket of the present invention includes an insulating housing 1, a socket 2, a key module 4, a microprocessor 5, a micromotor 6, a wire 7, and a connecting shaft 8. The surface of the insulating housing 1 has jacks 2, and plastic buckles 3 are provided on both sides of the insulating housing 1, which can realize the connection and separation of the socket and the wall. The jack 2 is connected to the grid circuit 9 through the wire 7 on the back of the insulating housing 1, and supplies power to electrical equipment through the jack 2. The wire 7 is wound on the connecting shaft 8 , and the connecting shaft 8 is connected with the output shaft of the micro motor 6 . A microprocessor 5 is fixed inside the insulating housing 1 , the output end of the key module 4 is connected to the input end of the microprocessor 5 , and the output end of the microprocessor 5 is connected to the input end of the micromotor 6 .

When in use, press the "+" button microprocessor 5 to output a control signal to make the micromotor 6 rotate, and the wire to stretch; shrink.

An extensible wall socket of the present invention uses the plastic buckles 3 on both sides of the insulating housing 1 to separate the socket from the wall, and then uses the button "+" to control the rotation of the micro motor 6 to extend the wire, solving the problem of This solves the problem of insufficient length of electrical power cords; at the end of use, use the button "-" to control the micro-motor 6 to shrink the wires, which greatly increases the use range of the socket and is very convenient.
