Description

A kind of offset-fed antenna pitching assembly

Technical field

The utility model relates to a kind of offset-fed antenna, is specifically related to a kind of offset-fed antenna pitching assembly, belongs to the communication equipment technical field.

Background technology

Large-scale offset-fed antenna generally is column at present, and its reflector and feed all are installed on the column, and column itself is fixedly connected with ground through anchor bolt; Therefore this offset-fed aerial position is fixed; Can not be suitable for some special occasion (like forest fire or earthquake etc.), and this column offset-fed antenna adopts is Worm-gear type pitching assembly, its complex structure; The reflecting surface luffing angle is regulated cumbersome; Need to use specific purpose tool could realize that the pitching component process requires high, manufacturing cost is also higher.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of offset-fed antenna pitching assembly is provided, and it is simple in structure, and is easy to adjust, and technological requirement is low, and manufacturing cost is lower, can be applicable to portable offset-fed antenna.

The purpose of the utility model is achieved in that a kind of offset-fed antenna pitching assembly, and be characterized in: it comprises support bar, pull bar and universal joint, and said post upper is set with clip; Said pull bar lower end is passed clip and is plugged in the support bar; Said universal joint has two, and said two universal joints are arranged at support bar lower end and pull bar upper end, universal drive shaft pipe joint in said support bar lower end is equipped with respectively; Be connected through screw rod I between universal drive shaft pipe joint and the universal joint in said; Be set with adjusting nut I on the said screw rod I, said adjusting nut I is connected through screw rod II on the said pull bar with between the universal joint between support bar lower end and universal joint; Be set with adjusting nut II on the said screw rod II, said adjusting nut II is between pull bar upper end and universal joint.

Said universal joint is made up of universal drive shaft pipe joint I, coupling block and universal drive shaft pipe joint II, and said universal drive shaft pipe joint I and universal drive shaft pipe joint II form with coupling block respectively and be rotationally connected.

Compared with prior art, the beneficial effect of the utility model is:

A kind of offset-fed antenna of the utility model pitching assembly, it is through the degree of tightness clip position of adjusting yoke easily, thereby realizes the adjusting of antenna elevation angle degree; Adjusting nut can be finely tuned the antenna elevation angle degree; Therefore whole pitching modular construction is simple, easy to adjust, with respect to original worm and gear form; Greatly reduce the technological requirement and the cost of manufacturing, can be applicable to column and portable antenna simultaneously.
