Simultaneously, building site temperature is higher summer, and the power extension line is at the environment during operation of higher temperature, and the plug during operation can produce the heat equally, and a large amount of heats are piled up and are not in time dispelled the heat, and the plug probably takes place hot melt phenomenon, leads to plug and supply socket to melt integrative, and is serious, can lead to the emergence of conflagration.

SUMMERY OF THE UTILITY MODEL

Based on this, it is necessary to prevent falling the ability poor to current power extension line, does not have the condition of safe outage detection, provides a power extension line, prevents falling the ability reinforce, can detect the plug temperature through temperature sensor, prevents that the high temperature from leading to the plug hot melt.

The utility model provides a power extension line, includes plug, controller, socket and cable, the controller passes through the cable is connected respectively the plug with the socket, the socket cross-section is big font, the socket has four grafting portions, and first grafting portion and second grafting portion are three hole sockets, and third grafting portion and fourth grafting portion are double socket, be provided with temperature sensor in the plug, be provided with the switch on the controller, temperature sensor passes through the controller with the switch electricity is connected, the socket is made by PVC elasticity plastic.

Preferably, one end of the cable close to the socket is provided with a fixing lug.

Preferably, the temperature sensor is a positive temperature coefficient thermistor.

Preferably, the two sides of the plug are provided with concave-convex grains.

Preferably, the controller is further provided with an indicator light.

The utility model discloses an useful part lies in: 1. the socket designed by the utility model is made of PVC elastic plastic, has certain elasticity, small volume and strong anti-falling capability, and can simultaneously provide power for a plurality of devices, thus having strong practicability; 2. the utility model discloses be provided with temperature sensor inside the plug, when the plug temperature rose to preset threshold value, temperature sensor's can give an electric signal of controller, and then the control switch disconnection prevents that the plug from leading to the hot melt because of the high temperature.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, the power extension cord comprises a plug 1, a controller 2, a socket 3 and a cable 4, wherein the controller 2 is connected with the plug 1 and the socket 3 respectively through the cable 4, the cross section of the socket 3 is in a large character shape, the socket 3 is provided with four plugging portions, a first plugging portion 31 and a second plugging portion 32 are three-hole sockets, a third plugging portion 33 and a fourth plugging portion 34 are double sockets, a temperature sensor 11 is arranged in the plug 1, a switch 21 is arranged on the controller 2, the temperature sensor 11 is electrically connected with the switch 21 through the controller 2, and the socket 3 is made of PVC elastic plastic. Specifically, the socket 3 with the large-shaped cross section has a small volume and certain elasticity, and is stronger in falling resistance compared with the extension socket. Moreover, the four plug parts are completely protected by the socket 3, electric shock can be prevented, and the service performance of the socket 3 cannot be influenced even if the socket is dragged to slide on the ground. Further, be provided with temperature sensor 11 in plug 1 inside, temperature sensor 11's one end is that protrusion plug 1 and supply socket (not shown in the figure) are connected the face, can the real-time detection surface temperature of plug 1 during operation, when the surface temperature of plug 1 was too high, temperature sensor 11 transmitted this signal of telecommunication for controller 2, and is further, and controller 2 is inside to have temperature control circuit, and this temperature control circuit is prior art, and no longer repeated here. After the controller 2 acquires the electric signal through the temperature sensor 11, the temperature control circuit controls the switch 21 to be switched off, so that the situation that the surface temperature of the plug 21 is too high during working, hot melting is caused, and potential safety hazards are caused can be prevented. When the plug 1 has cooled down, the user can close the switch 21 and the power extension cord can continue to operate.

As shown in fig. 1, the cable 4 is provided with a fixing lug 41 near one end of the socket 3. Specifically, fixed ear 41 sets up on cable 4, conveniently runs through fixed ear 41 through connecting pieces such as screw, and fixed socket 3 is on the wall, and under the condition that socket 3 can not fall to the ground when ground ponding, this power extension line of use that also can be convenient.

As shown in fig. 1, the temperature sensor 11 is a positive temperature coefficient thermistor. The plug 1 is provided with raised grains 12 on two sides. An indicator light 22 is also provided on the controller 2. Specifically, the concave-convex grains 12 arranged on the plug 1 increase friction force, and the plug 1 is convenient to pull out and insert. An indicator lamp 22 is provided on the controller 2 to notify the user whether the socket 3 is charged or not, thereby preventing a safety accident.
