1. Field of the Invention
The present invention generally relates to screw covers, and more particularly to a screw cover for a portable electronic device. The invention relates to a contemporarily filed application titled “SCREW CAP FOR A PORTABLE ELECTRONIC DEVICE” and having the same assignee with the instant invention.
2. Prior Art
Currently, screw covers are widely used in electronic apparatuses including portable electronic devices in order to keep screws hidden. An example is found in the mobile phone model no. N188 marketed by Samsung Company. The mobile phone includes a columnar screw cover. The screw cover is made of plastic, and is set in a screw hole over a screw. The diameter of the screw cover is slightly greater than that of the screw hole, so that the screw is blocked from accidentally coming out from the screw hole. However, in disassembly, it is difficult to prise the screw cover out, and the screw cover can be easily damaged or even destroyed in this process.
Therefore, a screw cover which is easily assembled and disassembled is desired.
Accordingly, an object of the present invention is to provide a screw cover which is conveniently assembled and disassembled.
To achieve the above-mentioned object, a screw cover of the present invention is for being secured in a screw hole of a mobile phone. The screw cover comprises a cap made of stretchable material, and a post coaxially covered by the cap. The cap comprises an end having a round opening. A diameter of the end is slightly less than or the same as a diameter of the screw hole. The post comprises a top column. A diameter of the top column is slightly greater than a diameter of the round opening, so that the post is engaged in the round opening in assembly. The diameter of the end is thus expanded to be slightly greater than the diameter of the screw hole, so that the whole screw cover can be securely fixed in the screw hole. In disassembly, the top column is pushed so that the post moves down, and the diameter of the end returns to its original size. The screw cover can then be easily dropped out from the screw hole. The screw cover fully utilizes interengaging structures of the cap and the post and the elasticity of the cover. This makes assembly and disassembly of the screw cover quick and convenient.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

The post 20 includes a base 26, a middle column 24 extending from the base 26, and a top column 22 extending from the middle column 24. The base 26, the middle column 24, and the top column 22 are coaxial. The base 26 includes a main body 260, and two wedges 262 extending from approximately opposite sides of the main body 260 respectively. A diameter of the main body 260 is slightly greater than a diameter of the chamber 16. A diameter of the middle column 24 is less than the diameter of the main body 260, and greater than a diameter of the opening 122. The top column 22 includes an exposed surface 222. The diameter of the top column is less than the diameter of the middle column 24, and slightly greater than the diameter of the opening 122.

In disassembly, the post 20 is pressed down partly in the space 322 between the screw 34 and the screw cover 100. The outer diameter of the cap 10 returns to its original size, which is smaller than the diameter of the screw hole 32. Then when the mobile phone 300 is inverted, the cap 10 and the post 20 can be easily dropped out from the screw hole 32.
From the above description, it can be seen that the screw cover 100 of the present invention fully utilizes the interengaging structures of the cap 10 and the post 20 and the elasticity of the cap 10. This makes assembly and the disassembly of the screw cover 100 quick and convenient.
It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages. The example herein before described is merely a preferred or exemplary embodiment of the invention.
