Abstract

The utility model relates to a foldable multidirectional director antenna, comprising a main director, two auxiliary directors and four director laminates, wherein the main director and the auxiliary directors are movably connected through the director laminates; the joints between the directors and the director laminates are movably fixed through short aluminum pipe vibrators which are arranged on the directors and taken as hinge shafts; the director laminates can rotate around the hinge shafts to drive the auxiliary director to rotate. When the antenna is in use, only the auxiliary directors need to be expanded and the director laminates are fixed through bolts. When the antenna is packaged and transported, the bolts are loosened to fold the auxiliary directors. The utility model has concise structure and low cost and is more convenient to assemble and use.

Description

A kind of folding multi-direction director antenna

Technical field

The utility model relates to a kind of folding multi-direction director antenna, is meant a kind of multi-direction director of antenna with folding functional especially.

Background technology

For the better radiofrequency signal of catching, increasing outdoor use television antenna all selects to adopt multi-direction director, and multi-direction director generally is made up of a main director and several secondary directors, the structure more complicated, debug more loaded down with trivial details, volume ratio is huger, and it is very inconvenient to pack, store, transport.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned prior art deficiency, and provide a kind of simple in structure, debug the multi-direction director of folded doublet more easily, not only pack, store, the secondary director of antenna is collapsible when transporting is integrated with antenna master director, and can directly secondary director be launched in use, just can use by bolt director doubling, not need to use other standing finish.

For solving the problems of the technologies described above, the utility model by the following technical solutions:

The multidirectional director of a kind of folded doublet, include main director and secondary director, also include two big director doublings and two little director doublings, couple together by big director doubling and little director doubling between secondary director and the main director, come movable fixing with hinge in the junction of director and director doubling.The director doubling is that rotate in the axle center with the hinge of main director and director doubling junction, thereby drives the rotation of secondary director.Be reserved with the fixedly position, hole of director doubling on the director doubling with on the trunk of main director, launch secondary director after, the director doubling is fixed by bolts on the mobile jib of main director by this position, hole.

After adopting such structure, secondary director can be realized folder function, and launching the back only needs just can fix with bolt, need not take other standing finish.The utility model is simple in structure, installation (perhaps packing) is simple and easy, only secondary director need be launched get final product during use with bolt director doubling, the dismounting set bolt can not fold secondary director with main director and be integrated when using, need not dismantle secondary director, save the space, deposit conveniently.

Description of drawings

Be described in further detail below in conjunction with the drawings and specific embodiments and the utility model.

Fig. 1 is the utility model perspective view.

Fig. 2 is the utility model parts decomposing schematic representations.

Fig. 3 is the schematic diagram under the utility model folded state.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but not as to qualification of the present utility model.

Referring to figs. 1 to Fig. 5 as can be seen the utility model comprise: the antenna aluminum strip, antenna pole, big director doubling, little director doubling, the multi-direction director of described antenna is provided with a main director 6 and two

secondary directors

3,7, main director 6 is at the middle part, two

secondary directors

3,7 are arranged on the both sides of main director 6, become certain included angle between secondary director and the main director, director doubling 4 is used at two ends respectively, 5,1,2 connect, big director doubling 4,5 at front end, little director doubling 1,2 in the rear end, movable hinge is done with short aluminum pipe oscillator respectively in the junction, like this, big director doubling 4,5 just can rotate as the axle center with oscillator 8, little director doubling 1,2 just can rotate as the axle center with oscillator 9, rotate thereby drive secondary director.Be reserved with two fixedly

aperture positions

14,15 of director doubling on the trunk of main director, on large and small director doubling, also there is suitable with it position, hole, launch secondary director in use, the director doubling can be fixed on the trunk of main director by

hole

14,15 and suitable with it position, hole with bolt.The bolt at

removal hole

14,15 places can be realized the folding of secondary director when depositing.Described director doubling 4,5,1,2, each all is to be formed by upper shell and the mutual buckle closure of lower house, two ends have the activity of being used for fixedly to be used for fixing the fixed hole position of director doubling on trunk in the position, hole and of director support bar respectively.Described main director 6 is made up of nine short aluminum pipes 10 and the strut 11 of drawing money on credit, and nine short aluminum pipes are connected on the strut of drawing money on credit side by side, and passes the hole on the strut of drawing money on credit, and is screwed again.Described

secondary director

3,7 is made up of eight short aluminum pipes and a

support bar

12,13 respectively, and eight short aluminum pipes are connected on the support bar side by side, and the connected mode of its short aluminum pipe is identical with main director.

The examples of implementation of the above only are preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; being connected between director and the director doubling being not limited to hinge connects; can adopt other connected modes; so all equivalences of doing according to shape of the present utility model, structure and principle change, and all should be covered by within the protection range of the present utility model.

Claims

1. folding multi-direction director antenna, comprise: the main director (6) and the first secondary director (3) and the second secondary director (7), first director doubling (4), second largest director doubling (5), the first little director doubling (1), the second little director doubling (2), it is characterized in that: pass through first director doubling (4) between main director and the secondary director, second largest director doubling (5), the first little director doubling (1), the second little director doubling (2) is connected, junction at director and director doubling is come movable fixing with hinge, first director doubling (4), second largest director doubling (5) rotates as the axle center with hinge (8), little director doubling (1), (2) just can rotate as the axle center with hinge (9), rotate thereby drive secondary director, set bolt is by first hole (14), second hole (15) is fixed on telling director doubling on the support bar of main director.
