Abstract

The utility model relates to a portable indoor antenna, which mainly comprises a receiving board, steel wires, an upper cover and a bottom cover. The steel wires are mounted on two sides of the receiving board, the steel wire on one side is arranged into an n shape, the steel wire on the other side is arranged into a U shape while an interval is intentionally widened and the other end of the steel wire is elongated to be parallel to the n-shaped steel wire and at the equal space to the same, the assembled receiving board and the steel wires are disposed into the upper cover and the bottom cover, and thereby the portable antenna is formed. The portable indoor antenna is capable of receiving UHF (ultrahigh frequency) and VHF (very high frequency) signals due to arrangement of the steel wires, the signals are collected by the receiving board prior to being output, and the received UHF and VHF signals can be forwarded to a television, a computer or a radio. The portable indoor antenna is quite practical, and small in size so as to be portable in outgoing to conveniently receive signals.

Description

The portable domestic aerial

Technical field

The utility model relates to a kind of antenna, and it mainly relies on the arrangement mode of iron wire, and can receive the signal of UHF and VHF, cooperate the signal output of dash receiver again, can be for being connected use with TV, computer or broadcast receiver, and volume is little does not take up space, and conveniently carries.

Background technology

Present notebook computer; panel TV; computer is popularized gradually in general family; and become main flow gradually; and in order to reach better rating quality; and expansion notebook computer; panel TV functional; many people are the external domestic aerial of meeting usually; but general domestic aerial is generally a planar design and is hung on metope; and volume takes up space greatly; so indoor placement is more not attractive in appearance, and preferable digital television signal receiving position, regular meeting changes along with the environmental factor change; for example; the putting position of furniture; the putting position of TV; the switch of window etc., therefore, if desire to obtain best receiving quality; need constantly to adjust position and the angle that domestic aerial is put; very bother constantly, especially many angles can't be swung arbitrarily, make reception have a greatly reduced quality.

The utility model designer specializes in the manufacturing of electronic product and peddles work, because of higher and reception is not good in view of the cost of traditional product, so be to rely on specialty of itself and working experience for many years, actively drop into the research reform, after adding test, correction and the improvement of going through several, initiate out the utility model finally.

Summary of the invention

The utility model relates to a kind of portable domestic aerial, solves problems such as the higher and reception of the cost of traditional product is not good.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of portable domestic aerial, it comprises dash receiver, iron wire, loam cake and bottom, this iron wire is linked to the both sides of dash receiver, dash receiver after the assembling and iron wire place on the bottom, with screw loam cake and bottom are screwed togather locking, it is characterized in that: this iron wire that is positioned at a side of dash receiver is " door " font iron wire, this iron wire of the opposite side of this dash receiver is positioned at the corresponding end of this " door " font iron wire, and be arranged in a U-iron line, and the width of this U-iron line is greater than the width of this " door " font iron wire, this U-iron line one end is connected with dash receiver, the other end has one and prolongs iron wire, this prolongation iron wire protruded out dash receiver and utilize a bonding die and dash receiver cemented, this prolongation iron wire align with " door " font iron wire and and this " door " font iron wire between have a spacing.

Wherein: should have a width that can receive the UHF signal by " door " font iron wire.

Wherein: the prolongation iron wire of this U-iron line can receive the signal of VHF.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be: the arrangement mode that this antenna can utilize iron wire to form receives the signal of UHF and VHF, rely on dash receiver to concentrate back output again, and can utilize adapter to be connected use with TV, computer or broadcast receiver, increase the reception of signal, reach desirable rating quality, especially the design volume of antenna is little, can conveniently carry and can be in outdoor application.

Embodiment

At first, see also shown in Figure 1, it is three-dimensional exploded view of the present utility model, it is mainly by dash receiver 20, iron wire 21, loam cake 22 and bottom 220 are formed, this iron wire 21 is installed in the both sides of dash receiver 20, the dash receiver 20 wherein iron wire 21 of a side is arranged in ㄇ shape iron wire 210 (claiming " door " font iron wire 210 again), and can receive the signal of UHF, 21 of iron wires as for dash receiver 20 opposite sides are arranged in U-iron line 211 and painstakingly widen spacing, make the width of the width of this U-iron line 211 greater than this " door " font iron wire 210, one end iron wire of this U-iron line 211 is connected with this dash receiver 20, and the other end iron wire 212 that makes U-iron line 211 extend to align with this ㄇ shape iron wire 210 and and this ㄇ shape iron wire 210 between have a suitable spacing, make and prolong the signal that iron wire 212 can receive VHF, then dash receiver 20 and iron wire 21 are inserted bottom 220, utilize screw 3 that loam cake 22 and bottom 220 are screwed togather locking again, and form domestic aerial 2 (as shown in Figure 2).

Then, see also shown in Figure 3, it is the arrangement schematic diagram of the utility model iron wire, this iron wire 21 is installed in the both sides of dash receiver 20, a side that is positioned at dash receiver 20 is connected with ㄇ shape iron wire 210, and ㄇ shape iron wire 210 has a suitable spacing, in order to the signal that receives UHF, and in the corresponding end of ㄇ shape iron wire 210, extend a U-iron line 211 from dash receiver 20, and this U-iron line 211 is painstakingly widened spacing, and make and prolong iron wire 212 and convexedly stretch in dash receiver 20 and align with ㄇ shape iron wire 210 and a suitable spacing is arranged, it is fixing to utilize a glutinous sheet 201 will prolong iron wire 212 again, and can receive the signal of VHF, again the signal that receives is concentrated back output by dash receiver 20, and can utilize adapter and computer, TV or broadcast receiver connect the use (not shown), and cooperate the simple designs of dash receiver 20 by the arrangement mode of iron wire 21, can receive the signal of UHF and VHF, being positioned at indoor or outdoors can both use, not only cost is lower and volume is little, be fit to very much carry, and the brain of powering, TV or wireless signal receive, and be functional extremely strong.
