Title: Antenna and fixed base rotary positioning structure

Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   This invention relates to an antenna, more particularly to an antenna with a fixed base rotary positioning structure. 
   2. Description of the Related Art 
   As the present society fills up with information and knowledge, information exchange and communications between people have become more important day after day. While the network and communication technologies such as Internet, mobile communications, and wireless communications are developed and widespread in a fast phase. Wireless devices serve as the advanced communications tools, playing an important role in our daily work and life as well as giving an indispensable effect. However, a general wireless network device usually requires an antenna, which is a well-known art, for being used to effectively transmit and receive signals. Therefore, users can use any wireless network device to transmit or receive signals between wireless network devices via the visiting node of the wireless network, so that users can use wireless network devices to contact with the outside by means of the wireless network devices, and obtain the maximum effect within the shortest possible time. 
   In general, most conventional antennas have a base body, and a slim antenna fixed on the base body, such that the base body is set on the table and provided for the wireless network device to transmit and receive the wireless network device, and thus users can use the wireless network device to contact with the outside anytime anywhere. 
   In view of the blooming wireless network devices and actual user&#39;s demands, the inventor of this invention believed that a single base body and an antenna no longer can satisfy the requirements. That is, the prior-art fixed antenna can only be placed on a table for its application. In the meantime, the base and the antenna are limited by the fixed status, and thus the antenna cannot be adjusted to any angle freely. Further, the wire extended from the body of the antenna cannot be handled properly, which takes up too much space for the application without much flexibility, and even causes damages to the base and antenna due to the fixed connection, and further affects the effects of sending and receiving signals by the wireless network device. 
   Therefore, the inventor of this invention improved the design of the prior-art fixed antenna and its base according to the actual needs, such that the main body of the antenna not only can be rotated to adjust the angle and fixed into a position, but also can be set on a table or hanged onto the wall to solve the abovementioned problems, and make the application more convenient. Such arrangement not only greatly helps to improve the sales of the wireless network device manufacturers, but also benefits the extensive consumers. Thus, the research and development of a multifunctional product for the wireless device industry is an important urgent subject. 
   SUMMARY OF THE INVENTION 
   In view of the description above, the prior-art antenna and base are fixed, which cannot be adjusted to any angle at will, but can only be set on a table for use. Thus, the prior-art antenna and base cause all kinds of inconvenience. Based on the actual need of the market and users, the inventor of this invention conducted extensive researches and developments and experiments to develop “an antenna with a fixed base rotary positioning structure” to enhance the add-on value. 
   The primary objective of the present invention is to provide an antenna with a fixed base rotary positioning structure, which can be placed on a table or hung on a wall, comprising: a fixed base; a protrusion disposed on the fixed base and having an open end on one side; a chamber enclosed by the rest of three sides; a pivotal axial hole and an arc groove being correspondingly disposed on both sides of the inner wall of the protrusion, such that the pivotal axial hole and the arc groove precisely and pivotally coupling the pivotal axis and the protruded fixing point to the two corresponding sides at one end of the antenna, and the antenna using such pivotal axis as the rotary axis to adjust the antenna to any angle by the open end of the protrusion. In the meantime, the antenna can be moved along the arc groove and fixed by the protruded fixing point, and the antenna can be fixed on to a wall by at least one hanging hole disposed at the bottom of the fixed base. 
   The secondary objective of this invention is to provide a linear groove being extended from one of the two corresponding inner walls where the protrusion is coupled to the fixed base, such that a linear member is disposed on the antenna at the pivotal end of the protrusion, and being extended to the outside from one end by means of the positioning of the linear line of the linear groove.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention. Please refer to  FIGS. 1 and 3  for the “antenna with a fixed base rotary positioning structure” in accordance with present invention, comprising a fixed base  10 , a protrusion  20 , and an antenna  30 , wherein the fixed base  10  stably erects on a table or other fixed object (such as hanging on a wall). In  FIG. 1 , the protrusion  20  is disposed on fixed base  10 , and the cross section of the protrusion is substantially U-shape, and one side of the protrusion  20  is an open end on one side, and the rest three sides are successively connected to enclose a chamber  201 . Please refer to  FIGS. 1 and 2 , a pivotal axial hole  221  and an arc groove  222  are respectively disposed on two corresponding inner walls  22  of the protrusion  20 , wherein the arc groove  222  is extended from the center of the pivotal axial hole  221  to a predetermined distance. 
   Further, the antenna  30  is substantially in a bar shape. In  FIGS. 2 and 3 , the antenna  30  having a cross section substantially in the shape of a bar that works together with the chamber  201  of the protrusion  20 . However, the embodiment of this invention is not limited to this shape, and could be a cross section in any other shape that can collocate with the shape of the chamber  201 . Please refer to  FIGS. 1 and 2  again. In the figures, a pivotal axis  31  and a protruded fixing point  32  are disposed respectively on both corresponding sides at one end of the antenna  30 , and the pivotal axis  31  and the protruded fixing point  32  are pivotally coupled to the pivotal axial hole  221  and the arc groove  222  disposed on two corresponding inner walls  22  of the protrusion  20 , such that the antenna  30  can use the pivotal axis  31  as the rotary axis to turn and adjust the open side  21  of the protrusion to any angle (from 0 degree to 90 degrees as shown in  FIG. 3 ). In the meantime, the protruded fixing point  32  moves and fix the antenna  30  along the arc groove  222  into a position. 
   In a preferred embodiment of the present invention, a fixing hole  223  (as shown in  FIG. 1 ) is disposed respectively on both end points of the arc groove  222 , such that after the protruded fixing point  32  of the antenna  30  moves to the fixing hole  223 , the protruded fixing point  32  can be fixed into a position that makes the antenna  30  being horizontal or vertical to the fixed base  10  (as shown in  FIG. 3 ). However, the preferred embodiment of this invention is not limited to this. A plurality of fixing holes  223  disposed on the arc groove  222  can be used to provide a multiple of angles and fixing after the protruded fixing point  32  of the antenna  30  is moved into the fixing hole  223 .
