Abstract
The utility model discloses a telescopic link used to adjust the pointing of a portable paraboloidal antenna, comprising an adjusting screw (1); wherein, an adjusting nut (3) is arranged on the adjusting screw (1), a sliding sleeve (6) is sleeved on the adjusting nut (3), and a hollow tube (7) is in turn sleeved on the sliding sleeve (6); a set screw (5) for fixing the sliding sleeve (6) is arranged on the tubular wall of the hollow tube, and a plurality of threads are arranged at one end part of the hollow tube (7). The utility model has the advantages of simplifying the structure, and facilitating the carrying of the portable paraboloidal antenna.
Description
Technical field
The utility model belongs to the Course Exercise in Machinery Elements Design technical field, relates in particular to a kind of portable parabolin antenna that is used for and points to the adjustment expansion link.
Background technology
The adjusting of the portable parabolin antenna angle of pitch is meant and makes parabolic antenna axis alignment synchronous satellite when seeking star.At present, the governor motion of the portable parabolin antenna angle of pitch also has varied, and full automatic governor motion is generally arranged, and this governor motion must be with and seek star control system, could realize regulatory function, also has hand turbine-worm gearing etc. in addition.These governor motions are for the less parabolic antenna of bore (as about 0.8 meter), the weight ratio of the antenna that tends to increase, simultaneously these governor motion complex structures, volume big, make portable parabolin antenna carry inconvenience.
Summary of the invention
The utility model provides a kind of portable parabolin antenna simple in structure, easy to carry to point to the adjustment expansion link.
The utility model adopts following technical scheme:
A kind of portable parabolin antenna expansion link, comprise adjusting screw(rod), on adjusting screw(rod), be provided with adjusting nut, on adjusting nut, be arranged with sliding sleeve, on sliding sleeve, be arranged with hollow pipe, on the tube wall of hollow pipe, be provided with the holding screw that is used for fixing sliding sleeve, be provided with screw thread in the end of hollow pipe.
On adjusting screw(rod), be provided with the fastening screw nut that is used for fixing adjusting nut.
Compared with prior art, the utlity model has following advantage:
The utility model is simple in structure, easy to carry.Compare with governor motion of the prior art, the utility model adopts sheathed sliding sleeve on adjusting nut, be arranged with hollow pipe at sliding sleeve, and on the tube wall of hollow pipe, be provided with the holding screw that is used for fixing sliding sleeve, when needs are adjusted in than polarizers of big angle scope, can unclamp holding screw, elongation or the shortening that hollow pipe just can be by a relatively large margin makes antenna elevation angle to adjust in a big way like this; When needing fine setting, tighten holding screw, at this moment, the rotation adjusting nut, adjusting screw(rod) just can elongate or shorten in small range, realize the fine setting of antenna elevation angle, the utility model only adopts said structure just to realize the coarse adjustment and the fine setting of antenna elevation angle, is satisfying under the prerequisite of instructions for use, simplified the structure of governor motion greatly, simultaneously, because the utility model is simple in structure, make that also antenna is easy to carry when therefore being used for small-bore parabolic antenna.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model when being used for portable parabolin antenna.
Have among the above figure: adjusting screw(rod) 1, fastening screw nut 2, adjusting nut 3, pin 4, holding screw 5, sliding sleeve 6, hollow pipe 7, antenna holder 8, expansion link 9, base support 10.
Embodiment
Portable parabolin antenna points to adjust uses expansion link, comprise that material and model are the adjusting screw(rod) 1 of 1Gr18, M16, on adjusting screw(rod) 1, be provided with adjusting nut 3, on adjusting nut 3, be arranged with sliding sleeve 6, on sliding sleeve 6, be arranged with hollow pipe 7, on the tube wall of hollow pipe 7, be provided with the holding screw 5 that is used for fixing sliding sleeve 6, be provided with screw thread, on adjusting screw(rod) 1, be provided with the fastening screw nut 2 that is used for fixing adjusting nut 3 in the end of hollow pipe 7.
In the present embodiment, do not come off in order to make adjusting nut 3 in sliding sleeve 6, to rotate freely, can be at adjusting nut 3 upper edge circumference fluting, interference fit has pin 4 on the tube wall of sliding sleeve 6, and pin 4 just is located in the groove on the adjusting nut 3.
When mounted, end with expansion link 9 is connected on the antenna holder 8 earlier, the other end is connected on the base support 10, in the time need in bigger angular range, adjusting the angle of pitch of antenna, can unclamp holding screw 5, elongation or the shortening that hollow pipe 7 just can be by a relatively large margin makes antenna elevation angle to adjust in a big way like this; When needing fine setting, tighten holding screw 5, at this moment, unclamp fastening screw nut 2, rotation adjusting nut 3, adjusting screw(rod) 1 just can elongate or shorten in small range, realizes the fine setting of antenna elevation angle.
Claims (2)
1. a portable parabolin antenna points to adjust and uses expansion link, comprise adjusting screw(rod) (1), on adjusting screw(rod) (1), be provided with adjusting nut (3), it is characterized in that, on adjusting nut (3), be arranged with sliding sleeve (6), on sliding sleeve (6), be arranged with hollow pipe (7), on the tube wall of hollow pipe (7), be provided with the holding screw (5) that is used for fixing sliding sleeve (6), be provided with screw thread in the end of hollow pipe (7).
