A high interference-resistant digital receiver

Abstract

This invention discloses a high anti-interference digital receiver, comprising a hollow fixed chassis. Four threaded pin positioning holes are formed on the upper surface of the hollow fixed chassis. A carrier plate is fixedly connected to the inner wall of the hollow fixed chassis, and a circular block is fixedly connected to the upper surface of the carrier plate. This high anti-interference digital receiver, by using a hollow fixed chassis with four threaded pin positioning holes, allows operators to fix the hollow fixed chassis to a platform using the threaded pins. Compared to previous technologies, this not only makes the receiver body more robust but also relatively smaller in size. By setting two triangular locking heads on the load-bearing column, when the operator rotates the receiver body, the two triangular locking heads automatically engage with corresponding triangular locking slots under the action of a return spring, quickly positioning the load-bearing column. This facilitates adjustments to the receiver body's orientation, demonstrating the overall stability and flexibility of the device.

Description

Technical Field

[0001] This invention relates to the field of digital receivers, and in particular to a highly interference-resistant digital receiver. Background Technology

[0002] A digital receiver is a device that uses an analog-to-digital converter to digitize signals and then uses digital signal processing technology to achieve frequency conversion, filtering, demodulation, etc. Digital receivers are widely used in communication, radar, navigation systems, electronic countermeasures systems, IFF systems, and civilian radios and televisions, and are an important system for the future development of receivers. In order to solve the problem that signal receivers are prone to shaking and thus have poor signal reception, the existing technology generally adopts the method of increasing the weight on the bracket. This can prevent the signal receiver from shifting or tipping over in the event of a collision or strong wind, thus avoiding abnormal signal transmission. For example, the anti-interference signal receiver disclosed in Publication No. CN218734279U uses a weight-adding device to quickly increase the weight of the signal receiver. However, by adding a counterweight, the size of the receiver is indirectly increased, which occupies a lot of space and is inconvenient for staff to place. Moreover, the receiver is generally fixed on the bracket, and the staff cannot adjust its direction.

[0003] To address these issues, we propose a highly interference-resistant digital receiver. Summary of the Invention

[0004] The purpose of this invention is to provide a highly interference-resistant digital receiver to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high anti-interference digital receiver includes a hollow fixed chassis. Four threaded positioning holes are formed on the upper surface of the hollow fixed chassis. A carrier plate is fixedly connected to the inner wall of the hollow fixed chassis. A circular block is fixedly connected to the upper surface of the carrier plate. A circular opening is formed on the upper surface of the circular block. A bearing is fixedly embedded in the inner bottom wall of the circular opening. A rotating rod is fixedly connected to the inner ring of the bearing. A load-bearing column is fixedly connected to the top of the rotating rod. A support rod is fixedly connected to the top of the load-bearing column. A V-shaped support plate is fixedly connected to the top of the support rod. The receiver body is mounted on the right side of the V-shaped support plate. A circularly arranged triangular slot is formed on the inner wall of the circular opening. Two symmetrical sliding holes are formed on the outer surface of the load-bearing column. Triangular clips that fit the triangular slots are slidably connected inside each of the two sliding holes. Return springs are fixedly connected to the ends of the two triangular clips that are close to each other. The ends of the two return springs that are close to each other are respectively connected to the inner walls of the two triangular slots.

[0007] In a further embodiment, the upper surface of the hollow fixed chassis is provided with an opening, and a handle is fixedly connected to the inner wall of the opening.

[0008] In a further embodiment, a rubber protective pad is fixedly connected to the bottom surface of the hollow fixed chassis, and the number of rubber protective pads is three. An anti-slip sleeve is fixedly connected to the outer surface of the support rod.

[0009] In a further embodiment, an indicator light plate is fixedly embedded on the upper surface of the V-shaped support plate, and a parameter plate is fixedly connected to the left side of the V-shaped support plate.

[0010] In a further embodiment, a stabilizing block is fixedly connected to the outer surface of the circular block, and the bottom surface of the stabilizing block is connected to the upper surface of the carrier plate.

[0011] In a further embodiment, the inner wall of the sliding hole has two limiting grooves, and the interior of each limiting groove is slidably connected to a limiting block. The sides of the two limiting blocks that are close to each other are connected to the outer surface of the triangular chuck.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This device features a hollow fixed base with four threaded positioning holes, allowing operators to secure the base to the platform. This not only makes the receiver more robust than previous technologies but also reduces its size. Furthermore, two triangular locking heads on the support column automatically engage with corresponding slots when the receiver is rotated, facilitating quick positioning of the support column. This allows for easy adjustment of the receiver's orientation and demonstrates the overall stability and flexibility of the device. Attached Figure Description

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

[0021] Please see Figure 1-5 In this invention, a high anti-interference digital receiver includes a hollow fixed chassis 1. Four threaded pin positioning holes 5 are formed on the upper surface of the hollow fixed chassis 1. A carrier plate 8 is fixedly connected to the inner wall of the hollow fixed chassis 1. A circular block 2 is fixedly connected to the upper surface of the carrier plate 8. A circular opening 12 is formed on the upper surface of the circular block 2. A bearing 13 is fixedly embedded in the inner bottom wall of the circular opening 12. A rotating rod 14 is fixedly connected to the inner ring of the bearing 13. A load-bearing column 15 is fixedly connected to the top of the rotating rod 14. A support rod 16 is fixedly connected to the top of the load-bearing column 15. A V-shaped support plate 3 is fixedly connected to the top of the support rod 16. A receiver body 4 is installed on the right side of the V-shaped support plate 3. A circular arrangement of triangular slots 18 is provided on the inner wall of the circular opening 12. Two symmetrical sliding holes 20 are provided on the outer surface of the load-bearing column 15. Triangular clips 19 that are adapted to the triangular slots 18 are slidably connected inside the two sliding holes 20. A return spring 21 is fixedly connected to the end of the two triangular clips 19 that is close to each other. The end of the two return springs 21 that is close to each other is connected to the inner wall of the two triangular slots 18 respectively.

[0022] The upper surface of the hollow fixed chassis 1 has an opening 24, and a handle 10 is fixedly connected to the inner wall of the opening 24. By setting the handle 10 on the hollow fixed chassis 1, it is convenient for the staff to lift the receiver body 4. Three rubber protective pads 9 are fixedly connected to the bottom surface of the hollow fixed chassis 1. An anti-slip sleeve 17 is fixedly connected to the outer surface of the support rod 16. By setting three rubber protective pads 9 under the hollow fixed chassis 1, the bottom of the hollow fixed chassis 1 can be protected. By covering the support rod 16 with an anti-slip sleeve 17, it is convenient for the staff to rotate the support rod 16. An indicator light plate 7 is fixedly embedded on the upper surface of the V-shaped support plate 3. A parameter plate 11 is fixedly connected to the left side of the V-shaped support plate 3. By setting the indicator light plate 7 on the surface of the V-shaped support plate 3, it is convenient for the staff to know whether the equipment is working properly.

[0023] A stabilizing block 6 is fixedly connected to the outer surface of the circular block 2. The bottom surface of the stabilizing block 6 is connected to the upper surface of the carrier plate 8. By adding a stabilizing block 6 to the surface of the circular block 2, the connection between the circular block 2 and the carrier plate 8 can be made more secure. Two limiting grooves 22 are opened on the inner wall of the sliding hole 20. Limiting blocks 23 are slidably connected inside the two limiting grooves 22. The sides of the two limiting blocks 23 that are close to each other are connected to the outer surface of the triangular chuck 19. By cooperating with the limiting grooves 22 and the limiting blocks 23, the triangular chuck 19 can be limited.

[0024] The working principle of this invention is:

[0025] First, the staff moves the receiver body 4 to a suitable position using the handle 10. Then, the staff places the hollow fixed base 1 on the ground and fixes it to the ground with screws. When the staff needs to adjust the orientation of the receiver body 4, the staff holds the anti-slip sleeve 17 and rotates the support rod 16 appropriately. At this time, the two triangular clips 19 on the load-bearing column 15 are forced and retract into the corresponding sliding holes 20. When the staff stops rotating the support rod 16, the return spring 21 pushes out the triangular clips 19 and makes them lock into the corresponding triangular clip slots 18, thus completing the orientation adjustment.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
