Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a portable parabolic antenna that can be easily carried.

[0002]

[Prior art]

 In the conventional portable parabolic antenna, the antenna part is divided into several parts, and each part is placed in a separate case for carrying.

[0003]

[Problems to be solved by the device]

 Since the conventional portable parabolic antenna described above must carry as many cases as the number of divided antenna parts, it is laborious to carry. In addition, when assembling and storing the parabolic antenna, it takes time because the divided antenna parts are taken in and out from the case, and there is a problem that the mobile antenna lacks mobility.

The present invention has been made in view of the above-mentioned problems, and it is a portable parabolic antenna that can be easily transported, can be installed and stored in a short time, and can improve mobility. For the purpose of providing.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an antenna that also serves as a reflector having a rotatable handle, a foldable electromagnetic horn, a reflector base, and a cover for covering the reflecting surface. The base and a fixing means for fixing the antenna base and the handle portion are preferably provided. Preferably, the outer shapes of the reflecting mirror and the antenna base are hemispherical, and the antenna base is used as a cover for the reflecting mirror. The structure will be such that the entire structure will be spherical when attached.

[0006]

According to the portable parabolic antenna of the present invention having the above-described configuration, the antenna base and the handle portion become a pedestal that rotatably supports the reflecting mirror by fixing each other with the fixing means, and the parabolic antenna is used. Make it possible. By attaching the antenna base to the reflecting surface, it becomes a cover to protect the reflector, making the parabolic antenna portable.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing a state where a portable parabolic antenna according to an embodiment is used as an antenna. Further, FIGS. 2A and 2B are external views showing the individual components.

In FIG. 1, reference numeral 10 denotes a portable parabolic antenna, which includes a reflecting mirror 1, an electromagnetic horn 2, a handle portion 3, and an antenna base 4.

In FIG. 2A, in the reflecting mirror 1, the inner reflecting surface 1 a has a parabolic shape and the outer wall has a hemispherical shape. The outer wall of the reflecting mirror 1 is made of a hard material. Further, stopper plates 1b are provided at several positions on the outer peripheral edge of the reflecting mirror 1. The electromagnetic horn 2 is composed of a horn body 2a, a horn supporter 2b, and a hinge portion 2c. The electromagnetic horn 2 is rotatably attached to the lower end of the outer peripheral edge of the reflecting mirror 1 via a hinge portion 2c. The handle portion 3 is rotatably attached to the left and right ends near the outer peripheral edge of the reflecting mirror 1 via the EL shaft 3a. The EL shaft 3a is attached to the reflecting mirror 1 with a screw, and is fixed to the reflecting mirror 1 by tightening this screw. That is, at this time, the handle portion 3 is fixed to the reflecting mirror 1. Further, a female screw 3b is provided at the center of the grip portion of the handle portion 3.

As shown in FIG. 2B, the antenna base 4 has a hemispherical outer shape and a hollow inner side having an opening having the same diameter as that of the reflecting mirror 1. The entire antenna base 4 is made of the same hard material as the reflecting mirror 1. A support shaft portion 4b having a male screw 4a is detachably attached to the outer center of the antenna base 4. The male screw 4a is screwed onto the female screw 3b of the handle portion 3. Further, on the outer peripheral edge of the opening of the antenna base 4, there is provided a locking portion 4c that locks with a stopper plate 1b provided on the reflecting mirror 1. When the antenna base 4 having such a structure is attached to the reflecting mirror as a cover, the entire shape of these is spherical (FIG. 3).

The installation and storage operation of the portable parabolic antenna of this embodiment having the above-mentioned configuration is performed as follows. When the portable parabolic antenna 10 is installed, the female screw 3b of the handle portion 3 and the male screw 4a of the antenna base 4 are screwed together, placed at an arbitrary position, and the angle of the reflecting mirror 1 is adjusted. The angle of the reflecting mirror 1 is determined by tightening the screw of the shaft 3a. Thereafter, the electromagnetic horn 2 is moved to a predetermined position to complete the installation of the portable parabolic antenna 10 (FIG. 1).

Next, when carrying the portable parabolic antenna 10, the electromagnetic hoe 2 is folded toward the reflecting surface 1a. Then, the screwing of the female screw 3b of the handle portion 3 and the male screw 4a of the antenna base 4 is released. After that, the reflecting mirror 1 and the antenna base 4 are aligned with each other, and the stopper plate 1b is locked to the locking portion 4c to complete the end of the parabolic antenna (FIG. 3). It should be noted that by removing the support shaft portion 4b, it is possible to use it for more convenient transportation.

In the portable parabolic antenna of the present embodiment having such a configuration, the antenna base serves as a cover for the reflecting mirror, and the outside of the reflecting mirror and the antenna base is formed of a hard member, so that the parabolic antenna can be transported. There is no need for a separate case. Also, when stored, it becomes a single sphere with a handle that can be easily carried. In addition, the installation and storage of the parabolic antenna does not require the components to be taken in and out of the case, which saves time.

The present invention is not limited to the above embodiment. For example, the outer shapes of the reflector and the antenna base are not limited to those shown in the drawings, and other shapes can be selected as long as they do not adversely affect the radiation surface of the reflector.

[0015]

[Effect of the device]

 As described above, according to the portable parabolic antenna of the present invention, the parabolic antenna can be easily carried, and the components of the parabolic antenna do not need to be put in and taken out from separate cases, so that installation and storage can be performed quickly. Therefore, maneuverability can be improved accordingly.
