The present invention relates to wire-winding devices, and particular to a wire-winding device, wherein a transmission line winds around a rotary base so that the transmission line can be wound in order. Thereby, the transmission line can be stored and carried conveniently.
UBS transmission lines are more and more popular since more and more electronic devices use UBS connectors for data communication. However, it induces a problem of storage of USB transmission lines. The prior art wire-winding devices have two problems. One is that the positioning unit of the wire-winding device has a rolling ball movable in a guide groove of a rotary disk for rotating and positioning the wire-winding device. However, the rolling ball is very small. It is easily to separate from the guide groove due to collision so as to destroy the wire-winding device. The other problem is that a center of a lower cover of the wire-winding device has a post which is formed by two semi-round rods. A center thereof is locked by a screw and a lateral notch thereof is embedded by a spiral spring. When the screw is locked into the post, the two semi-round rods are possible to be expanded. After using a long time, the ends of the spiral spring will separate from the notch so that the wire-winding device is destroyed.
Moreover, the prior art is not suitable to be carried outdoors. Further, the transmission line is too long to be wound conveniently and easily. Thereby, the transmission line will interact by itself so as to form many joints. When it is desired to use the UBS transmission lines, the user must take a longer time to release the wire-winding device.
Accordingly, the primary object of the present invention is to provide a wire-winding device, wherein a transmission line winds around a rotary base so that the transmission line can be wound in order. Thereby, the transmission line can be stored and carried conveniently.
Another object of the present invention is to provide a wire-winding device, wherein lower side of the upper cover is formed with a sector groove. A movable sheet is installed in a center of the sector groove. A front end of the movable sheet is installed with a block. The block is protruded from the movable sheet. Each of two ends of the upper cover has a post and a hole. Thus, the transmission line can be positioned properly.
A further object of the present invention is to provide wire-winding device, wherein a lower cover is extended with a post at a center of one upper side of the lower cover. A side of the post has a trench for fixing one end of the spiral spring.
A yet object of the present invention is to provide wire-winding device, wherein the wire-winding device has a simple structure and long lifetime.
To achieve above objects, the present invention provides a wire-winding device. The wire-winding device comprises an upper cover; a center of the upper cover being formed with a via hole; a lower side of the upper cover being formed with a sector groove; a movable sheet being installed in a center of the sector groove; a front end of the movable sheet being installed with a block; the block being protruded from the movable sheet; a center of the rotary base having a via hole; a top of the rotary base being formed with an annular track; the block being steadily embedded into the annular track; a spiral spring being positioned in a lower groove of the rotary base; a lower cover extended with a post at a center of one upper side of the lower cover; a side of the post having a trench for fixing one end of the spiral spring; a transmission line winding around the rotary base; a screw being screwed into the combining post of the lower cover through the via hole of the upper cover, a hole of a spiral spring and a center hole formed by winding the transmission line so as to form a wire-winding device.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to
An upper cover 1 is included. A center of the upper cover 1 is formed with a via hole 11. A decorating sheet 4 covers the upper cover 1. A lower side of the upper cover 1 is formed with a sector groove 12. A movable sheet 2 is installed in a center of the sector groove 12. A front end of the movable sheet 2 is installed with a block 21. The block 21 is protruded from the movable sheet 2. Each of two ends of the upper cover 1 has a post 13 and a hole 14.
A center of the rotary base 5 has a via hole 51. A top of the rotary base 5 is formed with an annular track 52. The block 21 is steadily embedded into the annular track 52.
A spiral spring 6 is positioned in a lower groove of the rotary base 5.
A lower cover 8 is extended with a post 81 at a center of one upper side of the lower cover 8. A side of the post 81 has a trench 82 for fixing one end of the spiral spring 6. Each of two ends of the lower cover 8 has a post 83 and a hole 84 for engaging the hole 14 and the post 13 of the upper cover 1. Thereby, the upper cover 1 and lower cover 8 cover the rotary base 5.
A transmission line 7 winds around the rotary base 5. Two ends of the transmission line 7 are connected to UBS connectors 71.
A screw 3 is screwed into the post 81 of the lower cover 8 through the via hole 11 of the upper cover 1, a hole of a spiral spring 6 and a center hole formed by winding the transmission line 7 so as to form a wire-winding device 100.
Referring to
With reference to
In the present invention, the wire-winding device can be added with a circuit board. Thereby, one end of the transmission line 7 can be installed with an earphone.
In the present invention, the wire-winding device can be added with circuit board having the function of data storage. The circuit board can be installed with a USB connecting hole for receiving the UBS connector for data communication. The transmission line 7 can be installed with an earphone for receiving music.
Advantages of the present invention will be described herein. In the present invention, a circuit board can be installed to the wire-winding device so as to increase the function of the wire-winding device. Moreover, the transmission line can be received effectively so that the transmission line will not interact by itself. Thereby, it can be carried easily. By the structure of the present invention, the problem of the destroy due to careless operation is resolved. Thereby, the structure of the present invention is simple and can be operated easily so as to have a longer lifetime.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
