Abstract
The utility model provides a special antenna for receiving soviet union satellite television programs. The utility model adopts a two rod supporting structure in a shape like the Chinese character 'ba', three connecting rods pitch adjustment, a clamping nut position adjusting mechanism and a spiral radiating body segment structure, overcoming the defects of large trishores volume, difficult pitch adjustment and mechanical operation of a fan arc shape, inconvenient debugging, etc. of the existing spiral antennae. The utility model is a seating and hanging dual-purpose single spiral TV antenna with the advantages of simple structure, light weight, convenient debugging and favorable receiving effect.
Description
The utility model is a kind of single-screw television antenna.This antenna is mainly used in the cooperation receiver, and tuner receives Soviet Union's satellite television programming.
Existing its bracing frame of single-screw television antenna adopts the tripod leg usually, bow and press down governor motion employing fan arc structure, ground plate adopts dull and stereotyped, and helical width of cloth beam adopts the fixedly overall structure of the number of turns, is exactly this as broadcasting with 1984 the 10th phases of TV tech magazine the 22nd page of helical antenna of being said.This antenna exists the volume heaviness, and difficulty of processing is big, adjusts shortcomings such as inconvenience.
The purpose of this utility model is to avoid the deficiency of prior art, provides a kind of simple in structure, and the seat that is easy to adjust is hung dual-purpose single-screw television antenna.
Bracing frame of the present utility model adopts splayed two bar structures and a little extension gusset, makes its extension dual-purpose, and bowing of antenna presses down adjusting employing three bar linkage structures, and the spiral radiation body adopts the merogenesis syndeton, and the antenna ground plate adopts parabolic shape.
Describe structure of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an A-A vertical view of the present utility model.
With reference to Fig. 1, splayed is propped up ground bar (7) by being threaded in the side of base (1), the length of two bars is according to the joint number decision of spiral, and the angle of two bars will make the center of gravity of total drop on the plane at Eight characters bar place, keeps the poised state of the angle of pitch under 0～90 ° of arbitrary situation.The gusset (2) that has hanging hole (22) can be according to using the needs hanger in wall by the opposite side of screw in base (1).The center of base (1) is fixed with middle strut (3) by clamp nut (8) up and down, in the lower end of strut (3) fix a connecting rod (4) that has strip hole (14) by screw (15), center pole (5) is separately fixed at the upper end of middle strut (3) and a certain position of slotted hole of connecting rod (4) by screw (17) and screw (16).Be welded with ring flange (19) on the center pole (5), be fixed on the ground plate (6) by screw (18).Helix (11) is fixed on the upper end of center pole (5) by strut (12).For the ease of debugging, helix is divided into 5 circles, one joint, connects a joint according to the strong and weak situation of signal again by helix joint (9) in the practicality, by knock-off joint (10) extension bar (13) is connected the termination of center pole (5) simultaneously.The output signal of helix is connected on the cable block (20) that is fixed on ground plate (6).Middle strut (3), connecting rod (4) and center pole (5) three bar linkage structures constitute bowing of antenna and press down governor motion, loosening screw (17), the position of adjustment screw (16) in strip hole (14), the angle of depression degree of adjustable antenna in 0～90 ° of scope.The middle part of middle strut (3) also has and has hole (21), to change the link position of connecting rod (4) and middle strut.Strut (3) can be finely tuned the azimuth of antenna easily during loose nut (8) rotated.Earth electrode (6) is the parabola of little focal length, but to improve reception and attractive, decorative.
The utility model is owing to adopt splayed two supporting foot structures, thereby volume reduces, and weight saving is simultaneously owing to adopt three connecting rods to bow to press down governor motion and helix merogenesis fixed structure thereby processing simple, easy to adjust.
Claims (2)
1, a kind of single-screw antenna, comprise spiral radiation body, ground plate, bow press down, orientation governor motion and bracing frame, it is characterized in that the orientation is regulated to adopt the clamp nut structure, bow to press down to regulate and adopt three bar linkage structures, bracing frame adopts splayed two bar structures, and helix adopts the merogenesis syndeton.
2, antenna according to claim 1 is characterized in that ground plate adopts parabolic shape.
