Abstract
The utility model relates to a nondirectional frequency adjustable whip antenna (WHIP ANTENNA). A second antenna section with a smaller diameter is matched with and arranged in a first hollow antenna section, wherein the tail end of the first antenna section is connected to a positioning base with antenna signal feed-in terminals, and the first antenna section is also provided with threaded holes and screws for steadily fixing the second antenna section in the first antenna section, so that users can adjust the length of the whip antenna conveniently. In such a manner, when the positioning base of the whip antenna of the utility model is combined with a vehicle or a base station, the adjusted length can not be changed under the vibration of the external force. The utility model can solve the problem that the frequency can not be adjusted existed in other fixed frequency antennae, and can avoid the defects existing in the existing whip antennae.
Description
Technical field
The utility model is about a kind of non-directive frequency adjustable type rod shape antenna (WHIPANTENNA), especially refer to a kind of after being adjusted into characteristic frequency length, can stablize this adjustment aft antenna length, do not reduce antenna length along with environmental turbulence, and can not cause transmitter infringement, cause the transmitting-receiving frequency skew and influence communication quality.
Background technology
Action vehicle or radio base station etc. are all installed rod shape antenna mostly at present, usefulness as the transmitting-receiving of wireless signal, with the common rod shape antenna of vehicle, because the each department opening can be made commercial wireless communication frequency band and inequality, add the unit that is responsible for the control wireless communication frequency band, can adjust the frequency of communication at any time, so, these rod shape antennas promptly are designed to the structure of scalable length, because antenna length has direct relation with the transmitting-receiving characteristic frequency.
See also shown in Figure 6, outside drawing for rod shape antenna, it mainly is made up of a holder 50, signal feed-in terminal separated 51 and plural number section 52～55 of telescopic tubes from the bottom to top, and the antenna length of so-called corresponding characteristic frequency, promptly be by the length of the top of going up a telescopic tube 55 most between wireless signal feed-in terminal separated 51, and after rod shape antenna length changes, promptly can change the frequency of rod shape antenna transmitting/receiving wireless signal, cause and to launch or reception unintelligible, and make the transmitter infringement.
Rod shape antenna (WHIP ANTENNA) makes things convenient for the user to adjust different length though have stretching structure, wireless signal with the transmitting-receiving characteristic frequency, but vehicle is in advancing, can make rod shape antenna length not change because of road conditions are good, or be installed in the rod shape antenna of base station, because external factors such as winds, and change antenna length, make transmitting-receiving frequency change and influence communication quality.The stretching structure of this rod shape antenna again, after often adjusting the antenna length structure, its stationkeeping ability can variation, can can't be fixed under the same length equally.So, sell a kind of regular length antenna on the market, promptly the user can be to the relevant capable rod shape antenna of buying a sufficient length of Communication Equipment, again according to the open communication frequency in locality or its length of communication frequency cutting of often using.
Above-mentioned microscler antenna is compared the advantage that telescopic rod shape antenna has easy regular length, but the frequent suitable length of cutting exactly of the person of being to use of puzzlement, if the too short suitable frequency of suitable length transmitting-receiving that then can't be cut to again of cutting, moreover, this antenna can't arbitrarily be adjusted transmitting-receiving frequency, therefore not only the consumer feels trouble also to need the frequent problem that solves the various people of disturbing after selling for the dealer who sells.So present rod shape antenna structure still has the necessity of its improvement.
Summary of the invention
Main purpose of the present utility model provides a kind of easy adjustment length that has, and the stable rod shape antenna of adjusting the adjustable frequency formula of back length function, makes the user can arbitrarily adjust the length of rod shape antenna, with the different communication frequencies of correct transmitting-receiving.
The employed major technique means of the utility model are to make this rod shape antenna include:
One positioning seat, for being arranged on the antenna Connection Block of wireless communication apparatus, it consists predominantly of an aerial signal feed-in terminal separated and a holder, and this aerial signal feed-in terminal separated is placed in this holder;
One first antenna segment, it is a hollow tubular body, its tail end is incorporated on the aerial signal feed-in terminal separated of this positioning seat, imports in the aerial signal feed-in terminal separated with the wireless signal that will receive and dispatch, and the nearly opening part of the side of this first antenna segment is formed with a screw that is communicated with the inner space; And
One second antenna segment is inserted in this first antenna segment, cooperates screw to be screwed together in the side screw of this first antenna segment, and second antenna segment is packed in this first antenna segment;
The utility model mainly designs a hollow first antenna segment, cooperate and insert second antenna segment that diameter is less, because the first line segment section is provided with screw and screw, second antenna segment stably can be fixed in first antenna segment, can easily adjust the length of rod shape antenna, and can be because of not being installed on vehicle or the base station, be subjected to external force vibration and change the length of adjusting, can solve many shortcomings of present rod shape antenna.

Embodiment
At first see also shown in Figure 1ly, be the exploded view of the utility model one preferred embodiment, it includes a positioning seat 10, one first antenna segment 20 and one second antenna segment 30.
Please cooperate shown in Fig. 2-4, this positioning seat 10 is for being arranged on the antenna Connection Block (not shown) of wireless communication apparatus again, and it consists predominantly of an aerial signal feed-in terminal separated 11 and a holder 12, and this aerial signal feed-in terminal separated 11 is placed in this holder 12.
Above-mentioned first antenna segment 20 is a hollow tubular body, its tail end is incorporated on the aerial signal feed-in terminal separated 11 of this positioning seat 10, import in the aerial signal feed-in terminal separated 11 with the wireless signal that will receive and dispatch, the nearly opening of the side of this first antenna segment 20 21 places are formed with a screw 22 that is communicated with the inner space.
Again, this second antenna segment 30 is inserted in this first antenna segment 20, cooperates screw 31 to be screwed together in the side screw 22 of this first antenna segment 20, and second antenna segment 30 is packed in this first antenna segment 20.
In the present embodiment, this first antenna segment 20 is bonded to the structure of the aerial signal feed-in terminal separated 11 of positioning seat 10, on this aerial signal feed-in terminal separated 23, be formed with a projection 110, its end face forms a groove 111, and in screw 112 of this upper protruding block 110 sides formation together with groove 111, first antenna segment, 20 tail ends are then joined groove 111 sizes and are extended a projection 23 in the centre position, to be inserted in the groove 111, cooperate a screw 113 to screw togather to this screw 112 afterwards, projection 23 in the groove 112 is packed in the groove 111, and makes this first antenna segment 20 be bonded on this positioning seat 10.
