The utility model is to realize above-mentioned purpose by following technical solution：
A kind of to stablize the front antenna for adjusting the angle of pitch, it is by upper backrest, lower backrest, mechanical self-latching hydraulic push rod and battle array
Surface antenna is constituted, it is characterised in that：The lower end of upper backrest is placed in the upper end of lower backrest, and its side passes through bearing A, bearing B and pin
Axle is movably hinged, and the mechanical self-latching hydraulic push rod that opposite side is hinged by bearing C and bearing D is connected, upper backrest by machinery from
Lock hydraulic push rod push-and-pull makes backrest be rotated around bearing pin；Upper backrest is fixed with front by the side equipped with mechanical self-latching hydraulic push rod
Antenna.
Described mechanical self-latching hydraulic push rod is made up of hydraulic motor, T-shaped screw rod, nut, guide pin bushing, sleeve and protective case,
The left end of guide pin bushing, which is equipped with mounting seat B, the right-hand member of guide pin bushing, is equipped with nut, and nut internal messing has T-shaped screw rod；Equipped with set outside guide pin bushing
Cylinder, the right-hand member of sleeve is equipped with motor base and mounting seat A, and motor base is built with hydraulic motor, the right-hand member of hydraulic motor and T-shaped screw rod
Connection；Protective case is fixed on mounting seat B and sleeve.
The mounting seat A and mounting seat B of described mechanical self-latching hydraulic push rod respectively with the bearing C in upper backrest and lower backrest
On bearing D be flexibly connected by bearing pin.
The beneficial effect of the utility model compared with prior art is：
This can stablize the front antenna of the adjustment angle of pitch due to being connected between upper backrest and lower backrest by hinge,
In the presence of hydraulic motor, gyration is changed into by linear motion by nut and T-shaped screw rod so that mechanical self-latching hydraulic thrust
Bar pushes up backrest and rotated to an angle, so as to realize the angular adjustment of front antenna, disclosure satisfy that maximum reentry angle is big
The purpose that antenna gain is not reduced in the case of 60 °, realizes the true and reliable of signal transmission.In addition, using T-shaped screw rod with
Nut, which coordinates, carries out push-and-pull regulation, and mechanical self-latching effect can be reached well.

Embodiment
This can stablize the front antenna of the adjustment angle of pitch by upper backrest 1, lower backrest 2, mechanical self-latching hydraulic push rod 4 and front
Antenna 3 is constituted, and the lower end of upper backrest 1 is placed in the upper end of lower backrest 2, and its side passes through bearing A5, bearing B6 and the moveable hinge of bearing pin 7
Connect, opposite side is connected by bearing C8 and bearing D9 the mechanical self-latching hydraulic push rod 4 being hinged, and upper backrest 1 passes through mechanical self-latching liquid
The pressure push-and-pull of push rod 4 makes backrest 1 be rotated around bearing pin 7；Upper backrest 1 is fixed with battle array by the side equipped with mechanical self-latching hydraulic push rod 4
Surface antenna 3.
Described mechanical self-latching hydraulic push rod 4 is by hydraulic motor 13, T-shaped screw rod 15, nut 16, guide pin bushing 18, the and of sleeve 14
Protective case 19 is constituted, and the left end of guide pin bushing 18, which is equipped with mounting seat B11, the right-hand member of guide pin bushing 18, is equipped with nut 16, the internal messing of nut 16
