Power cord spooling machine

Abstract

Disclosed a coiling machine for power cord comprises a coiling box, a coiling wheel inside the coiling box, limited rings on the two ends of coiling wheel, and crinkle spring inside the coiling axle sleeve to connect the coiling axle corn. The invention is characterized in that the protruded part of coiling axle sleeve is equipped a electric connecting component formed by a conducting outer layer, a insulated inner layer and a conducting axle corn; a coiling-proof wheel formed by stop arm and vertical binding post is arranged on the outside of limited ring, as a stop connecting component which can rotate to make a group of electrical contacts connect. The stop function which is synchronous to the electrical connection can reduce the tensity between plug and the power cord, to make the plug connect the adapter firmly; in addition, it coils without electric to improve the safety of household appliance which also can prevent the knotting inside the box.

Description

Technical field [0001] The invention relates to a wire winding appliance, in particular to a wire take-up box for power cords of household appliances. Background technique [0002] At present, the power cords of household appliances are wound behind the household appliances by the power cord itself. After the user loosens the winding for the first time, the remaining cord is dragged behind the machine. As the types of household appliances increase, the wires are spread out in all directions. Hanging, it looks messy, not only affects the interior appearance, but also adds trouble to the relocation. CN2708919Y proposes a wire winder to restore its original shape through a crimping spring, so that the pulled part can be rolled back into the box. This rewinding force is used to control the length of the power cord and change the dragging phenomenon of the power cord. The resilience of the spring is proportional to the length that is pulled out. The longer the length is, the greater t...

Problems solved by technology

[0002] At present, the power cords of household appliances are wrapped and hung on the back of the household appliances. After the user unwinds the wires for the first time, he drags the remaining wires behind the machine. With the increase of types of household appliances, the wires are spread out in disorder Hanging, it looks messy, which not only affects the appearance of the interior, but also adds trouble to the relocation

CN2708919Y proposes a wire winder that elastically restores the original shape through the crimping spring, so that the pulled out part can be rolled back into the box, and the length of the power cord can be controlled by this rewinding force, so as to change the dragging phenomenon of the power cord, but due to the crimping The rebound force of the spring is proportional to the pulled-out length, the longer the pull-out length, the greater the pull-back force, which makes the pull-out power cord plugged into the plug, and the spring-back force keeps the plug in tension all the time The pulling state affects the fastness and reliability of the joint between the plug and the socket

Furthermore, the longer the power cord, the greater the rebound force, and the greater the vibration and shaking force on the other end of the power cord during the rebound, which will easily make the electrical contacts of the electrical appliance itself loose due to vibration, thereby affecting the reliability of the electrical contacts.
