Description

  The present invention relates to a power adapter having a cord rewinding device, and more particularly, a rewinding device that winds an output cord into a power adapter body, and allows an output cord exposed to the outside to be built into the power adapter, thereby carrying, storing, and carrying. It relates to a power adapter that is convenient and saves space.

  As shown in FIG. 4, a generally known power adapter includes a main body 100, a power plug 200 for inserting the power supply into an outlet at one end of the main body 100, and providing an output cord at another end of the main body 100. An electric plug 400 is provided at 300, and the electric plug 400 is inserted into a socket of a mobile phone or a power socket of a notebook computer to be used for replenishing power or supplying power directly.

  Such an elongated output cord 300 of the power adapter cannot be wound into the main body 100, so that when the use of the power adapter is completed, the output cord 300 is exposed to the outside, which is inconvenient for storage and portable. It was troublesome. For this reason, the user generally ties the output cord 300 after folding it using a rubber band or a plastic tying tool, and unwinds the output cord 300 from the rubber band or the tying tool in use. However, even if the output cord 300 is bound, it is still inconvenient to use the power adapter or to carry, store, transport and package the power adapter.

  The main object of the present invention is to solve the shortcomings of the prior art, that is, the present invention provides a power adapter having a kind of cord winding device, which comprises an output cord in a main body of the power adapter. The user can operate a push button to allow the output code exposed to the outside to be built into the main unit, shorten the output code without changing the appearance of the main unit, and shorten the output code. It is intended to make the power adapter convenient and practical for both carrying and storage.

  It is another object of the present invention to provide a power adapter having a kind of cord winding device, which allows the output cord to be housed in the power adapter in another manner, so that the whole power adapter is provided. It is assumed that the volume can be reduced.

The invention of claim 1 includes a power adapter main body, a center shaft, a rotary disk cover, a spiral spring, a rotary disk, a push button and a cover, wherein the main body is provided with a groove, and a power plug is provided at one end of the groove. A cord take-up device in which an output cord enters into the concave groove from one end of the main body, an electric plug is connected to another end of the output cord, and a cover is fixed to the concave groove of the main body with a screw. Power adapter,
The bottom of the concave groove of the main body is used as a push button locking edge and is used for locking the push button, a central axis is provided in the concave groove, and a rotary disk cover, a spiral spring, and a rotary disk are fitted to the central axis. The rotating disk cover is combined with the rotating disk to form a circular disk, a spiral spring is housed therein, and one end of the spiral spring is locked to the rotating disk cover. When the push cord at the back of the push button is pushed through the board, the output cord exposed to the outside is wound inside the main unit, and the push block is pushed toward another side. A power adapter having a cord winding device, characterized in that the output cord is formed to be locked.
According to a second aspect of the present invention, in the power supply adapter having the cord winding device according to the first aspect, the push button locking edge at the bottom of the concave groove of the main body has an arc shape, and the arc shape push button is locked. And a power supply adapter having a cord winding device.
According to a third aspect of the present invention, in the power supply adapter having the cord winding device according to the first aspect, a locking block is provided at a front end of the push button, and the locking block presses the output cord against the inner wall of the main body to lock the output cord. The power adapter is provided with a cord winding device.

  The power adapter equipped with the cord take-up device of the present invention improves the drawbacks of the commercially available power adapter, and also studies the power line recovery device of general electric products, and its principle is widely used at present. The technology is novel and the technology is undisclosed and has novelty before the filing of the application.

  As shown in FIGS. 1 to 3, the present invention includes a combination of a main body 1, a center shaft 2, a rotating disk cover 3, a spiral spring 4, a rotating disk 5, a push button 6 and a cover 7.

  The main body 1 has a concave groove 11 having an opening on one side, and the bottom of the concave groove 11 is an arc-shaped push button locking edge 12 for locking the push button 6 (FIG. 2). A push block 61 is fixed to the back surface, and a power plug 13 is provided in the main body 1 at the upper end of the concave groove 11 and is inserted into an outlet to serve to conduct power. An electric plug 400 is connected to one end of the output cord 300 (FIG. 1), inserted into a socket of a mobile phone or a power socket of a notebook computer, and the other end enters the groove 11 from the front end of the main body 1. In addition, it passes through the center shaft 2, the rotating disk cover 3, the spiral spring 4, and the rotating disk 5, and enters the outer edge of the rotating disk 5 from outside the center of the rotating disk 5. The center of the turntable cover 3, the spiral spring 4, and the turntable 5 is fitted to the center shaft 2 fixed in the concave groove 11 of the main body 1, and the turntable cover 3 and the turntable 5 are joined to form a circular disk. A recoverable spiral spring 4 is housed inside the spiral spring 4, and the outermost end of the spiral spring 4 is locked to the turntable cover 3. After the arc-shaped push button 6 is locked to the arc-shaped push button locking edge 12 of the main body 1, the leftmost cover 7 is fixed to the main body 1 by screwing the screw 8 into the screw hole 14 of the main body 1. To form the appearance shown in FIG.

  As shown in FIG. 3, when the push block 61 at the back of the push button 6 is at the left position of the push button engaging edge 12 of the main body 1, the engaging block 62 of the push button 6 does not lock the output cord 300. At this time, the output cord 300 is wound around the turntable 5 by the recovery force of the spiral spring 4, and the output cord 300 is stored in the main body 1. When the push block 61 of the push button 6 is pushed and the push button 6 is moved rightward, the locking block 62 of the push button 6 presses the output cord 300 against the inner wall of the main body 1 to form a locking state, Thus, the output cord 300 is locked and cannot be moved. When the output cord 300 is pulled out by the electric appliance plug 400, the push block 61 of the push button 6 is pushed to the left and the push button 6 is also moved to the left to release the locked state. I can't get any more. Therefore, the power adapter of the present invention can take up the output cord 300 in the power adapter to make it convenient for carrying, packing, and storing.

  The above is a preferred embodiment of the present invention, but modifications to achieve the same effect are possible, for example, a device for turning an output cord around an electric appliance by turning a push button, or a power cord for a general electric pot The power cord can be collected in the electric pot by simply releasing the power cord pulled outward, and the power line can be collected in the power adapter. If any, they shall fall within the scope of the present invention.

It is a perspective view of the present invention. FIG. 2 is an exploded view of the present invention. It is sectional drawing of this invention. It is a perspective view of a well-known technique.
