Description

BACKGROUND OF THIS INVENTION

1. Field of this invention

This invention relates to a satellite block-down receiver set having an adjustable mounting, more particular to a satellite block-down receiver set used in a dish aerial which uses a plurality of satellite block-down receivers to receive different satellite signals. Each of the satellite block-down receivers can obtain an excellent receiving effect by means of the mounting which incorporates with the satellite block-down receivers and makes the orientation of each satellite block-down receiver relative to a reflector of the dish aerial adjustable.

2. Related art of this invention

In the course of receiving the satellite signals, a dish aerial which comprises a dish bracket, a dish reflector, and a satellite block-down receiver located in the focus point of the reflector is usually used. The satellite block-down receiver is generally composed of a horn, a wave guide, and a processing circuit, and can receive and process the satellite signals and then output the processed satellite signals to a TV receiving system. However, following up the development of the satellite system, the source of the satellite signal is also diversified and pluralized. Thus, the adaptive scope and the orientation of each dish aerial should be adjusted in accordance with the difference in orientation of the satellite. Therefore, a plurality of dish aerials are necessary for receiving various satellite signals.
However, for the sake of saving space, a shared dish aerial and a plurality of satellite block-down receivers to receive satellite signals are normally used. That is, a plurality of adjacent satellite block-down receivers are arranged in the focus point of one reflector. Fig 1 shows a conventional embodiment that fixes two satellite block-down receivers to an arm of the dish bracket via a conventional mounting dedicated for a single satellite block-down receiver. As shown in Fig. 1, the satellite block-down receivers 3a and 3b are combined as a satellite block-down receiver set. The satellite block-down receiver set is detachably fixed to the arm 2 of the dish bracket via a mounting 1 which is dedicated for a single satellite block-down receiver. However, since the mounting 1 can only hold one satellite block-down receiver 3a, only the horn of the satellite block-down receiver 3a can be located on the focus point of the reflector of the dish aerial. The other satellite block-down receiver 3b is located in a position offsetting from the focus point of the reflector and thus obtains a receiving effect far worse than satellite block-down receiver 3a. As a result, a bad receiving effect is obtained using the combination of the satellite signals received by these two satellite block-down receivers.

SUMMARY OF THIS INVENTION

The object of this invention is to provide a satellite block-down receiver set having an adjustable mounting which can make the orientation of each satellite block-down receiver of the invention, relative to the reflector of the dish aerial, adjustable.
The other object of this invention is to provide a mounting by which at least one satellite block-down receiver can be fixed on the arm of the dish bracket, and the orientation of each satellite block-down receiver relative to the reflector of the dish aerial can be adjusted so as to obtain an excellent and balanced receiving effect

As shown in Fig. 2, the satellite block-down receiver set 10 comprises two block-down receiver bodies of 101a, 101b being adjacent to and coupled to each other, and a mounting 100 for coupling and holding the two block-down receiver bodies 101a and 101b. The mounting 100 comprises a coupling part 110 integrally formed as a whole with the two block-down receiver bodies 101a and 101b, and a fixture part 120 being mounted on the arm 2 of the dish bracket (not shown). The coupling part 110 comprises a coupling portion 111 integrally formed with the block-down receiver bodies 101a and 101b and an extension portion 113 extending from the coupling portion toward the fixture part 120. Moreover, the fixture part 120 comprises a fixing portion 121 being mounted on the arm of the dish bracket and a protruding portion 122 extending from the fixing portion 121.
As shown in Fig. 3, the fixing portion 121 comprises an upper frame 121a and a lower frame 121b. The lower frame 121b is coupled to the upper frame 121a by means of four long screws 121d being inserted from the bottom side thereof to the topside thereof. A rectangular hole is formed between the upper and lower frame 121a and 121b and used for receiving the arm 2 of the dish bracket. Four bevel faces 121c are formed in the four comers of the rectangular hole so as to receive different sizes of rectangular or circular arms 2. More detailed, by virtue of the provision of the bevel face 121c, the gap between the upper frame 121a and lower frame 121b, and the long screws 121d, the arm 2 of the dish bracket could be inserted into the fixing portion 121.
The protruding portion 122 of the fixture part 120 comprises a first protruding plate 122a and a second protruding plate 122b. The first protruding plate 122a is provided with a pivot hole 122c through which a pivot screw 130 can penetrate. The pivot screw 130 can be coupled, by thread, to a thread hole 111a provided in the coupling portion 111. According to the above mechanism, the first protruding plate 122a can movably overlap to the coupling portion 111 and the coupling part 110 can swing against the fixture part 120 around the pivot screw 130. The pivot screw 130 and the pivot 122c construct a shaft bracket mechanism. A locking screw 122d which functions as a locking mechanism is coupled to the second protruding plate 122b for abutting at the side wall of the extension portion 113 such that it pushes the extension portion 113 against the first protruding plate 122a and thereby fixing the swing angle of the coupling part 110 relative to the fixture 120 when the extension portion 113 of the coupling part is inserted into a space between the first protruding plate 122a and second protruding plate 122b. Moreover, as shown in Fig. 2, a pointer 122e is provided on the upper edge of the second protruding plate 122a, and a set of angle indicating scale 113a is provided on the extension portion 113 of the coupling part. Thus, the swing angle between the coupling part 110 and the fixture part 120 is easily identified.
Based on the above structure, the orientation of each satellite block-down receiver relative to the reflector of the dish aerial could be adjusted by virtue of the swing of the coupling part 110 relative to the fixture part 120 around the shaft bracket mechanism, when the fixture part 120 is fixed to the arm 2 of the dish bracket Thus, a suitable orientation of each satellite block-down receiver is available and an excellent and balanced receiving effect could be obtained.

Most of parts of the satellite block-down receiver set in the second embodiment are similar to those shown in the first embodiment except the following. First, the coupling portion 211 in the second embodiment is composed of an upper claming part 211a and a lower clamping part 211b, both thereof being combined together by means of screws. The lower clamping part 211b is provided with an extension portion 213 extending therefrom. Second, there is only one protruding plate 222 provided on the fixture part 220. Moreover, the extension portion 213 is provided with a curved slot 213a for receiving a locking screw 222d, and a pivot hole 213b for receiving a pivot screw 230. The protruding plate 222 of the fixture part 220 is provided with a through hole 222a for receiving the locking screw 222d, and a thread hole 222b for coupling with the pivot screw 230. Furthermore, the pointer 213c is provided on the extension portion 213 of the coupling part and the angle scale 222c is provided on the edge portion of the protruding plate 222 of the fixture part 220.
According to the above structure, the coupling part 210 can be supported by the pivot screw 230 and then swing relative to as well as change its angle to the fixture part 220, when the pivot screw 230 is inserted through the pivot hole 213b and coupled to the thread hole 222b. The orientation of each satellite block-down receiver relative to the reflector of the dish aerial would be changed as the angle of the coupling part 210 to the fixture part 220 is changed. Moreover, the orientation of the coupling part 210 relative to the fixture part 220 can be fixed by virtue of the clamping of the locking screw 222d and a nut 222e when the thread end of the locking screw 222d is inserted through the through hole 222a and the curved slot 213a and then coupled to the nut 222e. Briefly, the main difference between the second embodiment and the first embodiment is the provision of the coupling part which is constructed separately from the satellite block-down receiver body. By means of the above mechanism, the mounting composed of the coupling part 210 and the fixture part 220 can also be used to support a conventional satellite block-down receiver set which is not provided with an adjustable mounting.
