A kind of hand held antenna

Technical field

The utility model relates to a kind of hand held antenna, specifically refers to a kind of hand held antenna that is applicable on the books displacement disc point device.

Background technology

Radio RF recognition technology (being called for short RFID) is to utilize RF-wise to carry out the noncontact two-way communication, to reach automatic recognition objective and to obtain related data, because identification work is efficient and convenient, again need not manual intervention, and can work in the various environment, thereby be widely used in all trades and professions.

When being applied in places such as library, bookstore as above-mentioned RFID, can mail electronic tag in books or the article, people need remove recognition objective with a hand-hold type read write line.And be integrated with the fixedly-mounted antenna on the general hand-hold type read write line, this class hand-hold type read write line is comparatively heavy, especially general hyperfrequency hand-hold type read write line, in order to handle lot of data, read write line also bundles use with microcomputer, makes that the entire equipment volume is big, deal is heavier, as handheld device, hold up hold more painstaking, very inconvenient.For this reason, the handhold RFID read write line that people design a kind of novelty comes, as Chinese patent Granted publication number for " the separate type handhold RFID read write line " of CN200986709Y just disclosed so a kind of device, this device has adopted omnidirectional's telescopic antenna, when reading nearby label, antenna shortens, when reading at a distance label, antenna is elongated, by stretching out of antenna, prolong reading/writing distance, and reduce antenna volume, antenna and soft-key button switch are integrated, be a handheld device, read write line is the another one autonomous device, adopts cable to connect between two equipment, can alleviate the weight of handheld device so greatly, also make things convenient for user's operation.

The utility model content

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of novel structure is provided, and be convenient to equally hold up hold, hand held antenna that reading distance is adjustable.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this hand held antenna includes the housing of built-in aerial, the radio frequency line that links to each other with above-mentioned antenna is stretched in outward outside the described housing, it is characterized in that: be hinged with one handle on the described housing, and the hinge point of housing and handle is provided with angle location piece and location notch.

Preferred version of the present utility model is, described case design becomes frame type structure, antenna is positioned at the first side of this frame type structure, above-mentioned handle is hinged on one end, corresponding second side, this first side and locates, and on described second side, have the groove that holds for described handle, compact overall structure also is convenient to the operator and is gripped like this.

In above-mentioned preferred version, can also include the power amplifier switch that control antenna reads, the control line that links to each other with this power amplifier switch is also outer stretches in outside the described housing, with in time, the power amplifier of control antenna opens or closes easily, avoids unconsciously misreading.In this scheme, the bottom of groove preferably has a through hole, power amplifier switch be installed in the corresponding handle of this lead to the hole site on, and the power amplifier switch press section can be exposed to this through hole.When handle was accommodated in the groove fully, the press section on the power amplifier switch was exposed to this through hole like this, and the user can utilize forefinger or middle finger to push power amplifier switch after gripping housing; And after opening handle, can push the press section of power amplifier switch with thumb, such operation meets the application of force characteristics of human finger, thus have operation easily, advantage easily.

In such scheme, also can comprise the power amplifier indicator light that is serially connected on the control line, this power amplifier indicator light is to be installed in away from being good on the handle end of hinge point, to know the working condition of power amplifier switch conveniently, intuitively.

Comparatively Shi Yong scheme is, on housing, also have the through wires hole that is adjacent to described hinge point, said radio-frequency antenna and control line by this through wires hole after outer stretching in outside the housing, can have the trough that supplies radio frequency line and control line to hold this moment in handle surfaces, above-mentioned radio frequency line and control line can be hidden in wherein and grasp, and just can avoid radio frequency line and control line in the use to be affiliated to phenomenon on the foreign matter effectively.

In above-mentioned preferred version, described bottom portion of groove can have a projection, and has the draw-in groove that fastens with this projection on the handle of correspondence, when handle is accommodated in the groove fully, can prevent freely opening of handle effectively by projection and the engaging of draw-in groove.

Preferably, on the inner walls of above-mentioned antenna both sides, also be fixed with screen respectively, in case stop signal scattering and misreading of causing.

Compared with prior art, because the utility model has been set up handle, and this handle can also rotate with respect to housing, thereby during the books on reading differing heights, can be by means of flexible rotation, the location of handle, make the interior antenna of housing approach the electronic tag of being read as required, to play the effect of flexible housing, so the utility model in use, have equally easy to operate, the characteristics that reading distance is adjustable, and overall structure is simple, rationally, grip good hand touch, so be specially adapted on the books displacement disc point device.
