Abstract

The utility model is an antenna structure which puts the base plug into the rotary set, makes the spring plate closely sticking between the base plug and the rotary set, then inserts the bar seat of the antenna into the opening terminal of the base plug, utilizes the rotary set to arrange the antenna assembly hole of the body finishing the antenna structure. When moving the antenna to choose the receiving position, the bent type metal tube can be bent to any angle by using the antenna bar seat. The base plug and the antenna bar seat rotate in the rotary set in which the spring plate produces a elastic friction resistance to make the antenna bar seat left-right rotate for 360 degree and locate anywhere to choose the best radiation receiving direction.

Description

Antenna structure

Technical field

The utility model provides a kind of antenna structure, and is easily improper because of the direction or the application of force of bending when especially bending at general antenna, and the shortcoming that antenna fractures is improved.

Background technology

Press, use for various communication apparatus, the radiation receptivity of antenna often influences the effective communication distance, be to increase the radiation gain value with the structure of strengthening antenna itself, deficiency with the radiation receptivity that solves antenna, providing communication apparatus bigger, more effective communication distance, is the direction that all communication producers mainly study improvement, also is not to use the most important demand of person.

The little shape antenna that is built in the communication apparatus has the advantage of avoiding antenna to expose, reduce overall volume, by many users are liked, yet, because the radiation electric wave itself has directivity, plug-in antenna can be selected best reception orientation by rotary antenna, the user can rotate the plug-in antenna of this communication apparatus along with the difference of place to use or direction, make the direction of this plug-in antenna can be in the face of the orientation of best radiation intensity, to bring into play good radiation receptivity, so plug-in antenna still is the main flow of the antenna structure of existing various communication apparatus.

Known plug-in antenna as shown in Figure 1, it is that bottom plug 20 is put into revolving sleeve 30, again with mast base 10 ' insert by the open end 21 of bottom plug, and can utilize revolving sleeve 30 plants to be assembled in the antenna assemblies hole of body, promptly finish an antenna structure, when desiring rotary antenna selective reception orientation, bottom plug 20 and mast base 10 ' be able to rotation in revolving sleeve 30, receive the orientation to select best radiation; But its mast base only can be done the rotation of 360 degree, and mast base itself can't bend, and can't select best radiation to receive the orientation.

So, antenna structure as shown in Figure 2 also appears on the market, its be equally by mast base 10 ', bottom plug 20 and revolving sleeve 30 are formed, this mast base 10 ' be by an aerial head 11, one sheath 12 and one can not roll over formula metal wire 13 ', but an end of its bottom plug 20 and mast base 10 ' join has protruded out a pair of protruding arm 22, should on same axial location, respectively be provided with a screw 221 to protruding arm 22, wave joint 40 and be provided with one in bottom plug 20 and mast base 10 ' joint, it is to be inserted in rear flank in a pair of protruding arm 22 of bottom plug with a protruding arm 41, lock so in screw 221 with a screw 50 again, this waves joint 40 other sides and convexes with a base 42, in order to sheathed mast base 10 ', this mast base 10 ' promptly be able to screw 50 rotate freely for axle, make mast base 10 ' be bent into unspecified angle, and can do the left rotation and right rotation of 360 degree again.

Yet above-mentioned well-known antenna has following shortcoming on assembling is gone up and used

(1), this well-known antenna is outside the basic structure by antenna, must wave joint, protruding arm, screw and screw etc. in addition and constitute, its structure is complexity comparatively, not only assemble waste time and energy and cost higher.

(2), this well-known antenna be with screw in order to assembling bottom plug and wave joint, this screw volume is tiny, not only go up must be comparatively accurate in processing, and cause assembling to go up inconvenience greatly, and the fraction defective of increase product.

(3), its angle of waving joint bending has directivity, if user's desire bends mast base, and easily antenna is fractureed during with the direction bending of waving the joint bending.

(4), when rotating the well-known antenna pole socket, the user selects to the optimum reception orientation, owing to the frictional force that only depends on bottom plug and revolving sleeve inboard is located, when the user touches this mast base or vibrations because of carelessness, promptly easily cause this mast base displacement, and depart from the optimum reception orientation, and then influence the reception of communication body.

The utility model content

The utility model provides a kind of antenna structure, when especially bending at general antenna, the direction or the application of force of Yi Yin bending are improper, and the shortcoming that antenna fractures is improved, and can reduce the bent required part of antenna, not only can reduce cost and more can reduce the fraction defective of product, and mast base 360 degree left rotation and right rotation also can be located everywhere, really select best radiation to receive the orientation, and the situation of this mast base no orientation slippage in using, the shortcoming that can not produce the reception change or interrupt can be guaranteed the radiation reception of communication body in the best.

The technical solution of the utility model is:

A kind of antenna structure, it includes at least:

Mast base, it is made up of aerial head and folding metal wire;

Bottom plug, the one end forms the open end of planting for mast base;

Revolving sleeve, it is the cylinder for a hollow, and is equipped with the shell fragment that can be close between bottom plug and revolving sleeve in inner wall surface thereof when bottom plug is put into revolving sleeve.

Wherein: this mast base also includes sheath.

This bottom plug is formed with the shell fragment holder of holding mutually that makes this holder and revolving sleeve when putting into revolving sleeve for bottom plug away from a side of its open end.

This shell fragment is to be main body by a microscler sheet metal, and broken thereon several microscler holes that is provided with, and it is to cooperate the internal diameter of revolving sleeve and form external form cylindraceous and be inserted in this revolving sleeve.

The utility model antenna structure, it is that bottom plug is put into revolving sleeve, and shell fragment is close between bottom plug and revolving sleeve, mast base is inserted by the open end of bottom plug again, and can utilize the revolving sleeve plant to be assembled in the antenna assemblies hole of body, promptly finish an antenna structure; Therefore, when desiring rotary antenna selective reception orientation, the folding metal hose of mast base can be bent to a certain angle arbitrarily, and bottom plug and mast base are able to rotate in revolving sleeve, and produce a frictional resistance by the shell fragment in the revolving sleeve, mast base 360 degree left rotation and right rotation also can be located everywhere, select best radiation to receive the orientation really.
