Description

Technical Field

[0001] This utility model relates to the field of satellite antenna fixing technology, specifically to a high-frequency head clamp for satellite antennas. Background Technology

[0002] A satellite television receiving system includes: a parabolic antenna, a feedhorn, a low-noise block downconverter (LNB), and a satellite receiver; together they form a complete satellite receiving station.

[0003] A parabolic antenna reflects and focuses satellite signals from the sky onto a single focal point. A feedhorn, located at the focal point of the parabolic antenna, is a horn-like structure that focuses the satellite signal; it's called a feedhorn because it's the energy source, and it's required to collect all the energy focused at the focal point. Front-feed satellite receiving antennas typically use large-angle corrugated feedhorns. A low-noise block downconverter (LNB) downconverts and amplifies the satellite signal from the feedhorn before transmitting it to the satellite receiver. Lower noise levels in the LNB are better. The satellite receiver demodulates the satellite signal from the LNB, producing the satellite television image and audio signals.

[0004] With the development of civilian satellite television receiving systems, the current civilian satellite receiving antennas are widely used and come in various specifications to adapt to different usage and installation environments. After assembling the LNB assembly, the LNB is generally mounted on the feed rod. However, due to the differences in the size of satellite receiving antennas with different structures, the existing structures used to fix the LNB assembly have fixed connection dimensions, and some are even welded structures. The poor adaptability of the LNB bracket to different specifications of LNB assemblies and the poor assembly performance of the LNB bracket are the shortcomings of the existing LNB bracket technology. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-frequency head clamp for satellite antennas.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a LNB clamp for a satellite antenna, comprising a support body that mates with the end of the satellite antenna's feed rod and a semi-circular retaining ring that mates with the support body. The support body includes a snap-fit ​​portion, a support portion, and a semi-circular fixing portion. The lower end of the snap-fit ​​portion mates with the end of the satellite antenna's feed rod, the upper end of the snap-fit ​​portion is connected to the lower end of the support portion, and the upper end of the support portion is connected to the semi-circular fixing portion. The semi-circular fixing portion has its semi-circular arc surface facing upwards and mates with the semi-circular retaining ring. The circular fixing part and the semi-circular retaining ring cooperate to form the LNB clamping and mounting position. The clamping part includes a connecting body, a spring, and a limiting protrusion. One end of the upper end of the connecting body is connected to the support part. The lower end of the connecting body is provided with springs on its upper and lower sides respectively. The two springs are arranged in parallel, and the distance between the springs is adapted to the slot width at the end of the satellite antenna feed rod. Each spring is provided with a limiting protrusion, and the limiting protrusion is arranged facing outward. The end of the satellite antenna feed rod is provided with a corresponding limiting hole at the limiting protrusion.

[0007] In some embodiments, fixing ears are provided at both ends of the semicircular fixing part and the semicircular retaining ring.

[0008] In some embodiments, a guide post is provided on the side of the fixing ear on the semicircular retaining ring facing the semicircular fixing part, and a guide hole is provided on the fixing ear on the semicircular fixing part to cooperate with the guide post.

[0009] In some embodiments, the end face of the guide post is provided with a screw hole, and the side of the fixing lug on the semicircular fixing part away from the semicircular retaining ring is provided with a bolt that extends into the guide hole and mates with the screw hole.

[0010] In some embodiments, the support portion and the snap-fit ​​portion are arranged at a 135-degree angle.

[0011] In some embodiments, the semicircular retaining ring, the semicircular fixing part, the supporting part, and the snap-fit ​​part are all hollow.

[0012] In some embodiments, the semi-circular fixing part, after engaging with the semi-circular retaining ring, forms a ring-shaped arrangement of multiple heat dissipation grooves on the inner wall of the high-frequency head clamping mounting position.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by cooperating with the semi-circular retaining ring and the semi-circular fixing part, the high-frequency head can be easily fixed.

[0014] By using the snap-fit ​​structure and drilling holes at the end of the satellite antenna feed rod, the snap-fit ​​can be inserted into the end and elastically snapped in place, enabling rapid installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a LNB clamp for a satellite antenna, comprising a support body that mates with the end of the satellite antenna feed rod and a semi-circular retaining ring 1 that mates with the support body. The support body includes a snap-fit ​​part, a support part 2, and a semi-circular fixing part 3. The lower end of the snap-fit ​​part mates with the end of the satellite antenna feed rod, the upper end of the snap-fit ​​part is connected to the lower end of the support part 2, and the upper end of the support part 2 is connected to the semi-circular fixing part 3. The semi-circular arc surface of the semi-circular fixing part 3 is arranged facing upward and mates with the semi-circular retaining ring 1. The semi-circular fixing part 3 and the semi-circular retaining ring 1... After the circular retaining ring 1 is engaged, it forms the LNB clamping and mounting position. The retaining part includes a connecting body 4, a spring piece 5, and a limiting protrusion 6. One end of the upper end of the connecting body 4 is connected to the support part 2. The lower end of the connecting body 4 is provided with spring pieces 5 on its upper and lower sides respectively. The two spring pieces 5 are arranged in parallel, and the distance between the spring pieces 5 is adapted to the slot width of the end of the feed rod of the satellite antenna. Each spring piece 5 is provided with a limiting protrusion 6, and the limiting protrusion 6 is arranged facing outward. The end of the feed rod of the satellite antenna is provided with a corresponding limiting hole at the limiting protrusion 6.

[0022] When in use, according to the original satellite antenna feed rod, measure whether the width of the spring piece 5 is smaller than the slot at the end of the feed rod. If it is smaller than the slot width, then only a limiting hole needs to be drilled at the end of the feed rod to cooperate with the limiting protrusion 6. Insert the spring piece 5 into the end of the feed rod, and connect the support body and the feed rod through the cooperation of the limiting protrusion 6 and the limiting hole.

[0023] The high-frequency head is clamped and fixed by the semi-circular retaining ring 1 cooperating with the semi-circular fixing part 3 on the support.

[0024] Furthermore, in specific implementation, in order to simplify the process, fixing ears 7 are provided at both ends of the connection between the semicircular fixing part 3 and the semicircular retaining ring 1. A guide post 8 is provided on the side of the fixing ear 7 on the semicircular retaining ring 1 facing the semicircular fixing part 3. A guide hole 9 is provided on the fixing ear 7 on the semicircular fixing part 3 to cooperate with the guide post 8. A screw hole is provided on the end face of the guide post 8. A bolt 10 is provided on the side of the fixing ear 7 on the semicircular fixing part 3 away from the semicircular retaining ring 1, which extends into the guide hole 9 and cooperates with the screw hole.

[0025] After placing the LNB into the semi-circular fixing part 3, the semi-circular retaining ring 1 is fitted into the semi-circular fixing part 3, and the two guide pins 8 are inserted into the corresponding guide holes 9 respectively. After the fit is completed, it is fixed by bolts 10. At the same time, the bolts 10 are placed on the lower side. When the satellite antenna is located outdoors, rainwater and dust will not corrode the bolts 10, thus improving the service life of the components.

[0026] The support part 2 and the snap-fit ​​part are set at a 135-degree angle. This angle setting makes it easy for the LNB to be in a horizontal or slightly tilted state based on the original position of the feed rod after being clamped, which facilitates the adjustment of the antenna receiving position later.

[0027] Furthermore, in specific implementations, in order to reduce the structural weight of the components, the semi-circular retaining ring 1, the semi-circular fixing part 3, the supporting part 2, and the snap-fit ​​part are all hollow.

[0028] Furthermore, in specific implementation, in order to improve the heat dissipation effect at the high frequency head, the inner wall of the high frequency head clamping and mounting position formed by the semi-circular fixing part 3 and the semi-circular retaining ring 1 is provided with a plurality of heat dissipation grooves 11 in a ring shape. By setting the heat dissipation grooves 11, the contact area between the clamping part and the surface of the high frequency head can be reduced, so that the high frequency head can increase the contact surface with the air environment and facilitate heat dissipation.

[0029] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
