Abstract
The invention provides an antenna structure. The antenna structure is provided with a cylindrical cavity which is arranged at a connection place between a column and an antenna reflection plane for receiving one end of the column. The cylindrical cavity has a cross section which is a major arc which has an internal diameter equal to the diameter of the column. A major arc opening limits the movement of the column in the direction of the antenna reflection plane. In addition, the cylindrical cavity is provided with a restraining apparatus therein. The restraining apparatus extends towards an axis of the cylindrical cavity and the direction in which the apparatus extends is perpendicular to the direction in which the column extends within the cylindrical cavity, and restrains the movement of the column in the direction thereof. Since the restraining apparatus and the major arc opening are both integrated with the cylindrical cavity, the restraining of the movement of the column is stable. Further, since the restraining apparatus and the major arc opening and the cylindrical cavity are integrated, no extra manufacturing parts are needed, which reduces cost and makes it easy to install.

Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, knot below
Close accompanying drawing the detailed description of the invention of the present invention is described in detail.
Refer to Fig. 2 to Fig. 4, a kind of antenna structure that the present invention provides, including
One antenna reflective face (not shown), has concave surface and convex surface, for receiving and feedback letter
Number;
One column 300, is used for supporting described antenna reflective face, and it is fixed on by bindiny mechanism
On the convex surface of described antenna reflective face, column 300 one end connect antenna reflective face, the other end with
Base connects, and base is typically secured on wall or ground.
Specifically, the convex surface of antenna reflective face passes sequentially through back splint (not shown), regulation 200
Connect with column 300.Refer to Fig. 2, column 300 from base to antenna reflective face direction
Extend, when extending to below regulation 200, extend the most straight up so that column 300
Away from the cylindrical cavity 210 of one end entrance regulation 200 of base.
Continuing referring to Fig. 2, Fig. 3 and Fig. 4, the cross section of cylindrical cavity 210 is major arc,
Cylindrical cavity 210 medial surface is provided with opening 213, and this opening 213 is positioned at the string corresponding to major arc
Place, say, that cylindrical cavity 210 is the cavity formed by major arc, is i.e. positioned at its cavity hatch
At string corresponding to major arc.
And, cylindrical cavity 210, without bottom surface, is used for making column 300 enter cylindrical cavity 210.
Owing to string corresponding to major arc is less than the diameter of column 300, namely the width of opening 213 is less than
The diameter of column 300, during therefore column 300 then snaps in cylindrical cavity 210, when it is anti-to antenna
Penetrate the direction in face when moving, owing to the width of opening 213 is less than the diameter of column 300, column
300 cannot pass through opening 213 so that column 300 cannot continue to antenna reflective face direction to move
Dynamic.
Further, the opening 213 of the cylindrical cavity 210 that the present invention provides is provided with projection
212, refer to Fig. 4, this projection 212 is distributed in opening 213 both sides, in the diagram about
Horizontal line is symmetrical, and namely the perpendicular bisector about string corresponding to major arc is symmetrical.Projection 212
Side tangent with column 300 outer surface, in the top view shown by Fig. 4, by two dash forward
Playing 212 connections, the inevitable circle formed with cylindrical cavity 210 of the lines of formation intersects.Projection 212
Number at least two.The existence of its projection 212 reduces the width of opening 213 further,
Further limit the column 300 movement to antenna reflective face direction.
Further, the upper bottom surface of the cylindrical cavity 210 that the present invention provides is provided with restraint device,
This restraint device limits column 300 and moves up, and restraint device can take various forms, as
The upper bottom surface of cylindrical cavity 210 as restraint device, or can be arranged to barb shape, barb
The end contact of least significant end and column 300, owing to restraint device and cylindrical cavity 210 are integrated
Molding, makes and observes the column 300 fixing situation in cylindrical cavity 210 for convenience,
In the present embodiment, restraint device is two panels sheet metal 211, continues referring to Fig. 4, this two panels
Sheet metal 211 is positioned on major arc, and it extends from major arc to the axis direction of cylindrical cavity 210, gold
The bearing of trend belonging to sheet 211 is horizontal direction, namely with column 300 in cylindrical cavity 210
Bearing of trend vertical, above-mentioned two panels sheet metal 211 is symmetrical about horizontal line, also in the diagram
The perpendicular bisector being exactly the string corresponding about major arc is symmetrical, is limiting column 300 straight up
Give column 300 top uniform barrier force during motion.
The present invention provides a kind of antenna structure, sets in place of column 300 is connected with antenna reflective face
Putting the cylindrical cavity 210 that can accommodate column 300 one end, the cross section of cylindrical cavity 210 is internal diameter
Equal to the major arc of column 300 diameter, the width of such major arc mouth is then less than the diameter of column 300,
Column 300 cannot be continued to move to antenna reflective face direction by major arc oral area;
In cylindrical cavity 210, restraint device is set, the bearing of trend of this restraint device and column 300
Diffraction direction in cylindrical cavity 210 is vertical, so when column 300 in cylindrical cavity 210 to
During upper motion, can be stopped by restraint device, thus be limited column 300 in the direction
Motion.
It is all one-body molded with cylindrical cavity 210 due to restraint device and major arc mouth, therefore opposes
The restriction of the movement of post 300 is the most firm, additionally due to one-body molded, it is not necessary to the most additionally make
Part so that cost reduces, easy for installation.
Cylindrical cavity 210 when mounted, only need to be enclosed within vertical by the antenna structure that the present invention provides in addition
On post 300 so that cylindrical cavity 210 self only needs by gravity slide downward until column runs into
The stop of restraint device, then make cylindrical cavity 210 be automatically installed on column 300.
Obviously, those skilled in the art invention can be carried out various change and modification without deviating from
The spirit and scope of the present invention.If these amendments of the present invention and modification belong to right of the present invention
Require and within the scope of equivalent technologies, then the present invention is also intended to include that these are changed and modification
Including.
