In order to realize above-mentioned task, the utility model takes following technical solution to be achieved:
The manual rapid adjustment of a kind of middle-size and small-size radar antenna luffing angle mechanism; Comprise the bearing pedestal on the middle-size and small-size radar antenna pitching unit; It is characterized in that, slide is installed, be connected with briquetting on the slide in a side of bearing pedestal; Mobile support bar is installed in slide, and this support bar is connected with radar antenna; Location notch and location hole are arranged on the support bar, and there are left block and right block in the support bar both sides, and locking pin and compression spring are installed in the briquetting, and locking pin is fixed on the briquetting by clamping sleeve with the compression spring, and an end of locking pin is connected with handle; Ratchet is installed on briquetting, and this ratchet is positioned at support bar location notch top and rotates around bearing pin, and extension spring is arranged on the ratchet, and this extension spring is fixed by upper spring seat on the ratchet and the lower spring cup on the briquetting.
The manual rapid adjustment of the middle-size and small-size radar antenna luffing angle mechanism of the utility model, bearing pedestal is installed on the pitching support, and slide is installed in the bearing pedestal rotatable; Support bar is installed in the slide, can in slide, move, and adopts ratchet rapid adjustment position, locatees fast; In ratchet snapped in the different groove of support bar, support bar had just moved certain distance, and support bar is connected with radar antenna; Support bar promotes radar antenna and turns over certain angle, and the angle of pitch of corresponding radar antenna obtains adjustment.
When support bar moved, slide can rotate in bearing pedestal, prevented when support bar from moving stuck.
After the radar antenna angle of pitch was adjusted to predetermined angular, locking pin inserted in the support bar positioning hole corresponding, realized locking support bar fast.And the location notch number of positions can increase and can subtract on the support bar, and particular location can correspondingly be adjusted as required, has realized the manual rapid adjustment of radar antenna luffing angle to set angle, accurately location, reliable.It is simple in structure, and is easy to use, and requirement on machining accuracy is not high.
