Description

A kind of extended line

Technical field

The utility model relates to a kind of extended line.

Background technology

In the past, under many situations, people make between the place of electrical appliance and the power supply has certain distance, sometimes often only use a wire, length is not enough, just need be connected in series many wires this moment, traditional mode is with the mutual wringing of the end of a thread of electric wire together, then with insulating tape parcel, but this mode not only bothers but also dangerous, the extended line technology therefore occurred, the extended line that uses is mainly by interconnective plug at present, lead and socket are formed, as the patent No. is 91203882.9 multipurpose power source extended line, be with plastics at two of lead with plug, the connector injection mo(u)lding, becoming one can the slotting mutually integrated power supply line of head and the tail.The jack that a group or more is arranged on connector, can insert two-phase, the world of three-phase, domestic electrical standard power-line plug, the appliances power source line that is inserted is prolonged, sometimes reinstall the trouble of supply socket for the power supply that connects an electrical equipment to solve, can be widely used in household electrical appliance or instrument, instrument etc., but the defective of its existence is if extended line length is when longer, just may seem that extended line is very in disorder, influence the overall appearance of family, and knotting easily, use inconvenient, sometimes go out in the time of to carry extended line, also can cause and carry inconvenience, therefore 200720125355.9 Extension Line folding Unit China Patent No. has appearred again is, comprise an outer shell base, one is placed in the interior wheel seat in this outer shell base, one is arranged at an electric power output group of taking turns between card and this outer shell base inner face of wheel seat in this, and one reels on the wheel axial plane that is arranged at wheel seat in this and can stretched this outer shell base outer for the extended line that treat the grafting of electricity consumption article.This electric power output group comprise that a power line, three that can be plugged in a power supply source is fixedly arranged on this wheel seat at intervals this take turns becket on the card, three and be fixedly arranged on square horse on this outer shell base inner face in order to the conducting terminal, that is electrically connected this becket and this extended line, and three separately and in order to power connection end of electric connection of power supply line and becket.With so that integral body can reach use easy and convenient, and power supply stability and all good effect of fail safe, but its complex structure, part causes the cost height more, and production efficiency is low, needs further to improve.

The utility model content

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of simple in structure, low cost of manufacture, the extended line that conveniently uses and carry.

The utility model solves the problems of the technologies described above and the technical scheme that adopts is: a kind of extended line, include the plug and socket at housing, electric wire and electric wire two ends, it is characterized in that: the containing cavity of placing electric wire that described housing is combined to form by upper body and lower case, the center of this upper body is provided with first, the center of lower case is provided with second, first and second is combined to form a connecting axle, and described electric wire is wrapped on the connecting axle.

As improvement, form by first fixed axis and movable fastener for described first, this first fixed axis and upper body are one-body molded, the movable spacing center of movable fastener at first fixed axis, form by second fixed axis and movable bayonet socket for second, second fixed axis and lower case are one-body molded, and described movable bayonet socket is movable spacing at the center of second fixed axis, upper body and lower case by movable fastener cooperate with the clamping of movable bayonet socket carry out involutory.

As improvement, the outside activity of described connecting axle is with connecting bushing, and electric wire is wrapped on the connecting bushing.

As improvement, the side of described upper body and lower case all has the hole that supply lines passes through.

As improvement, flexibly connected over cap on the described socket, the over cap surface distributed has the sealing block that cooperates with socket aperture.

Compared with prior art; advantage of the present utility model is: constitute the containing cavity of placing electric wire by involutory upper body and lower case, make it simple in structure, low cost of manufacture; and production efficiency is higher; electric wire is wrapped on the connecting bushing, the pulling electric wire, and connecting bushing and then rotates; very easy to use; on socket, flexibly connected over cap, effectively prevented jack not water leaking-in or other impurity, used more safe and reliable.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As a kind of extended line as described in Fig. 1～3; include housing 1; the plug 3 at electric wire 2 and electric wire 2 two ends and socket 4; described housing 1 includes upper body 5 and lower case 6 again; this upper body 5 and lower case 6 are combined to form a containing cavity 7 of placing electric wire 2; involutory upper back housing 5 is to be rotatably connected on the lower case 6; be provided with first at the center of upper body 5; the center of lower case 6 is provided with second; form by first fixed axis and movable fastener 9 for described first; this first fixed axis and upper body 5 are one-body molded; movable fastener 9 movable spacing centers at first fixed axis; this activity fastener 9 intracardiac moving up and down in first fixed axis; form by second fixed axis 10 and movable bayonet socket 11 for described second; second fixed axis 10 is one-body molded with lower case 6; described movable bayonet socket 11 movable spacing centers at second fixed axis 10; movable bayonet socket 11 can be moved up and down at the center of second fixed axis 10; upper body 5 and lower case 6 be by movable fastener 9 cooperate with the clamping of movable bayonet socket 11 realize involutory; movable fastener 9 with make first and second cooperating of movable bayonet socket 11 simultaneously and be combined to form a connecting axle 12; also activity is with connecting bushing 13 in the outside of connecting axle 12; electric wire 2 is wrapped on the connecting bushing 13; utilize connecting bushing 13 to cooperate with the activity of connecting axle 12; it is more laborsaving that the people spurs electric wire 2; and use also convenient; have the hole 14 identical with the side of lower case 6 in the side of upper body 5; but these hole 14 supply lines 2 pass through; when exposing electric wire 2 outside containing cavity 7 and fall short of; can electric wire 2 be pulled out by this hole 14; because electric wire 2 is placed in the containing cavity 7; whole very in disorder of can not seeming; described socket 4 upper surfaces are provided with a two-phase jack 15; the lower surface of socket 4 is provided with two two-phase jacks 15; on the lower surface that is provided with two two-phase jacks 15, also flexibly connected over cap 16; over cap 16 surface distributed have the sealing block that cooperates with socket aperture; prevent water leaking-in or other impurity; use safer; described housing 1 integral body is formed by plastic production; make its overall low cost of manufacture; light weight; carry conveniently, the utility model is applicable to numerous consumers.
