Description

Technical Field

[0001] This utility model relates to the field of electronic information equipment technology, and more specifically, to a handheld GPS interference detection device. Background Technology

[0002] With the widespread application of Global Positioning System (GPS) technology, GPS interference detection equipment plays a vital role in military, civilian, and scientific research fields. In particular, in complex electromagnetic environments, the ability to quickly and accurately locate and eliminate GPS interference sources is of great significance for ensuring the normal operation of navigation and positioning systems.

[0003] When conducting GPS interference troubleshooting operations, corresponding GPS interference detection equipment is typically used. There are many types of GPS interference detection equipment on the market, most of which are large structures primarily installed on vehicles. They perform the detection operation as the vehicle moves. However, when encountering road surfaces where the vehicle cannot move, these vehicle-mounted GPS interference detection devices cannot approach the signal source and perform detection operations, affecting ease of use. Some GPS interference detection devices, while handheld, require an additional person to hold and operate the antenna, meaning that each detection operation requires two people working together, further impacting ease of use. Therefore, we propose a handheld GPS interference detection device. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Please see Figures 1-4 This utility model provides a technical solution: a handheld GPS interference detection device, including a GPS interference detection device body 1 and a receiving antenna 11 connected to the GPS interference detection device body 1 via a cable 12. A support base 111 is fixedly installed at the bottom end of the receiving antenna 11, and a gooseneck tube 14 is fixedly installed on the bottom surface of the support base 111. The outer diameter of the gooseneck tube 14 is between 1.5cm and 3cm, and the length of the gooseneck tube 14 is between 6cm and 10cm, so that the outer diameter and length of the gooseneck tube 14 are moderate, and the orientation of the receiving antenna 11 can be adjusted by bending the gooseneck tube 14 within the length range of the gooseneck tube 14.

[0027] Specifically, a vertical insertion tube 15 is fixedly installed at the bottom end of the gooseneck tube 14, and a limit ring 151 is fixedly installed on the vertical insertion tube 15. A helmet 3 is set on one side of the GPS interference troubleshooting machine body 1, and the helmet 3 is worn on the head. A connector 2 is set on the top of the helmet 3. The connector 2 includes a support cylinder 20 fixedly installed on the top of the helmet 3. The vertical insertion tube 15 and the support cylinder 20 are inserted and matched. A threaded sleeve 23 is slidably connected on the vertical insertion tube 15. The threaded sleeve 23 is threadedly connected to the support cylinder 20. The top wall of the threaded sleeve 23 abuts against the top surface of the limit ring 151. The threaded sleeve 23 is simultaneously fitted on the vertical insertion tube 15 and the support cylinder 20, which has the effect of limiting the vertical insertion tube 15. When the helmet 3 is worn on the head, the receiving antenna 11 is also worn on the head, which makes it convenient for the staff to directly hold the GPS interference troubleshooting machine body 1 for handheld use, achieving the effect of single-person direct operation.

[0028] In this embodiment, a socket 10 is fixedly installed on the main body 1 of the GPS interference detection machine, and a plug 13 is fixedly installed at the end of the cable 12. The plug 13 and the socket 10 are connected and engaged. This design not only simplifies the connection process and improves work efficiency, but also helps to ensure the stability and reliability of signal transmission, thereby improving the accuracy of GPS interference detection.

[0029] Specifically, the support cylinder 20 is provided with a plug hole 201 that connects the top to the outside. The bottom end of the vertical plug tube 15 is located in the plug hole 201 and is plugged into the plug hole 201, so that the receiving antenna 11 can be stably installed in the connector 2 on the helmet 3, which facilitates the quick installation and removal of the receiving antenna 11.

[0030] Furthermore, the dimensions of the vertical insertion tube 15 are matched with the dimensions of the insertion hole 201, ensuring the tightness and stability of the insertion; the outer surface of the threaded sleeve 23 is provided with anti-slip stripes 231, which increases the friction when the operator holds it and prevents slippage when rotating the threaded sleeve 23, thereby improving the convenience and safety of installation and disassembly.

[0031] In addition, a base plate 21 is fixedly installed at the bottom of the support cylinder 20. The base plate 21 is fixedly installed at the top of the helmet 3, which helps to increase the fixed contact area, enhance the overall stability of the connector 2, and also helps to evenly distribute the weight of the receiving antenna 11 onto the helmet 3, reducing the burden on the operator's head.

[0032] It is worth noting that the outer diameter of the base plate 21 is larger than the outer diameter of the support cylinder 20. Multiple support ribs 22 arranged in a ring at equal intervals are fixedly installed between the base plate 21 and the support cylinder 20. The support ribs 22 enhance the structural strength of the connector 2 and also help improve its durability and reliability in complex environments, thereby extending the service life of the equipment.

[0033] Finally, it should be noted that the GPS interference detection device body 1, cable 12, receiving antenna 11, and built-in power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0034] When using the handheld GPS interference detection device of this utility model, first, wear the helmet 3 correctly on your head. Then, align the vertical insertion tube 15 at the bottom of the receiving antenna 11 with the insertion hole 201 inside the support tube 20, and gently insert it until the bottom tube of the vertical insertion tube 15 is completely inside the insertion hole 201.

[0035] Next, slide the threaded sleeve 23 down from the top of the vertical insertion tube 15 until its top wall abuts against the top surface of the limiting ring 151, and simultaneously fit it onto the vertical insertion tube 15 and the support cylinder 20. Then, rotate the threaded sleeve 23 to make the threaded connection between it and the support cylinder 20 tight, thereby limiting the vertical insertion tube 15 and ensuring that the receiving antenna 11 is securely mounted on the helmet 3; at this time, the orientation of the gooseneck tube 14 and the receiving antenna 11 on it can be adjusted as needed by bending the gooseneck tube 14;

[0036] After installation, hold the GPS interference detector body 1 in your hand, make sure that the plug 13 at the end of the cable 12 is aligned with the socket 10 on the body, and gently insert it to achieve the connection. Then start the GPS interference detector body 1 to perform the troubleshooting operation.
