Benefit, and price is relatively cheap, therefore be widely used.Choosing can be considered as being fixed temporarily the occasion that platform antenna uses
With the sucker antenna of high gain, the length of antenna is not necessarily with excessive limitation.As China discloses a kind of " antenna structure " (application
Number：CN201120100053.2), including a shell；One is set to the digital television signal antenna in shell；One is set in shell
Broadcast singal antenna；One is set to the signal amplification list connecting in shell and with digital television signal antenna and broadcast singal antenna
Member；And one connect and extend hull outside with signal amplification unit connection unit.Therefore, day described in the utility model
Cable architecture may be disposed on roof and use, and receive digital shadow respectively using digital television signal antenna and broadcast singal antenna
Sound signal and analog broadcasting, and achieve the purpose that increase and receive signal efficiency, integrate circuit and strong fix.
Existing technology has the following problems：The anti-seismic performance more one of frequency spectrograph telescope signal antenna existing first
As, there is no enough shock resistances when being interfered by external environment, it will not be existing except first into row buffering to external force
Frequency spectrograph telescope signal antenna cap it is smaller, be unfavorable for receiving signal.
Utility model content
The purpose of this utility model is to provide a kind of frequency spectrograph telescope signal antennas, to solve to carry in above-mentioned background technology
The problem of going out.
To achieve the above object, the utility model provides the following technical solutions：A kind of frequency spectrograph telescope signal antenna, including
Cap, the cap are mounted on the surface of the first telescopic antenna, and being equipped with second immediately below first telescopic antenna stretches
Contracting antenna is equipped with third telescopic antenna below second telescopic antenna, and the is equipped with below the third telescopic antenna
Four telescopic antennas are provided with holder below the 4th telescopic antenna, and the holder is connect with pedestal by nut, the spiral shell
Female both sides and screw is provided on pedestal.
Preferably, the 4th telescopic antenna includes spring and connecting plate, and spring is equipped with above the connecting plate.
Preferably, the holder includes rotation axis, bolt, circular hole and main board, and the main board is internally provided with circle
Hole is equipped with rotation axis above the circular hole, and the rotation axis is connect by bolt with main board.
Preferably, the surface of the cap is equipped with semi-circular plate.
Preferably, first telescopic antenna is pyramidal structure.
Preferably, the cap is semicircular structure.
Compared with prior art, the utility model has the beneficial effects that：The utility model is provided with spring in structure, this
One is provided with the larger impact given in use if there is encountering external environment conducive to frequency spectrograph telescope signal antenna
Or in the case of vibrations, since the presence of spring can carry out a degree of buffering, make frequency spectrograph telescope signal antenna not
It easily snaps off, simultaneously as shaft is mounted on holder, in this way, antenna position can be adjusted by shaft rotary antenna
It sets, is more favorable for receiving signal, and when not using the antenna usually, so that it may to receive the antenna by the rotation of shaft
It rises, finally, semicircle harden structure is added in cap, in this case can increase the surface area of cap, reinforce antenna and receive letter
Number ability.
