Description

One-handed removable power plug

technical field

The utility model relates to a power plug, in particular to a power plug that can be pulled out with one hand.

Background technique

During the use of desktop portable mobile devices such as computers and chargers, it is often necessary to plug and unplug the power plug. For inserting the plug into the power socket, it is easy to realize whether the socket is fixed or not. But when power socket is not fixed, just be placed on tabletop or ground, then need just can finish with both hands operation to pull out plug. At this time, the other hand often has already grasped the object, so the object must be put down first, and then both hands cooperate to complete the action of pulling out the plug, which is particularly inconvenient.

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a power plug that can be pulled out with one hand, and the plug can be easily pulled out with only one hand, which is simple and convenient.

The utility model adopts the technical scheme to solve the technical problem: the power plug that can be pulled out by one hand includes a main body and pins installed on the main body, wherein the middle position of the main body is provided with a through hole that penetrates up and down, and a through hole is provided in the through hole. The top bar can slide up and down. When in use, hold the plug with one hand, and press down on the ejector rod with your fingers or palms, and the lower end of the ejector rod presses the socket to pull out the plug; the ejector rod is located in the middle of the plug, between each pin, avoiding the installation position of the pin , When the top is pressed, the force on the plug is balanced, which is convenient for the plug to be pulled out; the ejector rod is made of insulator material, which can prevent the ejector rod from conducting electricity and causing electric shock.

For further improvement, the left and right sides of the main body are respectively provided with protruding edges extending outward. The protruding edge is located on the upper end surface of the main body and is integrally structured with the main body. When the ejector rod is pressed down, an upward direction is required to act on the main body of the plug in reverse. The protruding edge is convenient for gripping, preventing slipping, and more helpful for pulling out the plug with one hand; the protruding edge is integrated with the main body, The structure is firm and the production is easy.

The lower end of the push rod is provided with a lower limit block protruding outward, and a groove for the lower limit block to be built in the main body is provided at the lower end of the through hole. The lower limit block prevents the ejector rod from being pulled out from the upper end of the through hole, resulting in loss of the ejector rod; and the lower limit block increases the area of the lower end of the ejector rod, increases the stressed area of the socket, and reduces the pressure.

The upper end of the push rod is provided with an upper limit block protruding outward. The upper surface of the upper limit block is an arc structure that protrudes upwards. The upper limit block prevents the ejector rod from slipping out from the lower end of the through hole, resulting in the loss of the ejector rod; and the lower limit block increases the force-bearing area of the lower end of the ejector rod. Reduces the pressure on the hand when pressing down, improving comfort.

The beneficial effects of the utility model are: the utility model has a reasonable structural design, and a push rod structure is added to the main body of the plug, so that the plug can be pulled out with one hand, which is more convenient and practical, and has a simple structure and low manufacturing cost, which is conducive to wide use.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to the accompanying drawings: this kind of power plug that can be pulled out by one hand includes a main body 1 and a pin 2 installed on the main body 1, wherein the middle position of the main body 1 is provided with a through hole 4 that penetrates up and down, and a through hole 4 is provided that can be used up and down. Sliding ejector pin 5. The left and right sides of the main body 1 are provided with protruding edges 3 respectively extending outward. The protruding edge 3 is located on the upper end surface of the main body and is integrally structured with the main body 1 .

The lower end of the push rod 5 is provided with a lower limiting block 5-2 protruding outward, and the lower end of the through hole 4 is provided with a groove 6 where the lower limiting block 5-2 can be built into the main body. The upper end of the push rod 5 is provided with an upper limit block 5-1 protruding outward. The upper surface of the upper limit block 5-1 is an arc structure protruding upward.

When the metal pin 2 of the plug is inserted into the jack on the socket, the ejector rod 5 is pushed upward by the action of the socket surface, which does not affect the normal operation of the metal pin 2 of the plug; when pulling out the plug, use the index finger and middle finger of one hand Clamp the two sides of the main body 1 of the plug, press the upper end of the ejector rod 5 with the palm of the thumb and apply force downwards. At this time, the two fingers clamping the main body 1 are not easy to slide due to the effect of the protruding edge 3, so that the ejector rod 5 will slide along the through hole. 4. Sliding down to the surface of the socket, under the force of the push rod 5, the main body 1 and pin 2 move in reverse to separate the plug from the socket. Since the ejector rod 5 has electrical insulation, the safety of the operator is ensured, and no electric shock will occur.

Although the present invention has been illustrated and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made within the scope of the claims.
