Description

Technical Field

[0001] This utility model relates to the field of contraband detection technology, specifically a portable drug and explosives detector. Background Technology

[0002] The explosives and drugs detector is a device that uses ion mobility spectrometry and integrates X-ray detection technology to detect trace amounts of explosives, drugs, toxic gases, and radioactive materials. It is fast, easy to operate, and highly sensitive, making it suitable for crowded places such as subways, airports, ports, and bus stations.

[0003] Currently, most explosives and drug detectors on the market have two detection methods: vacuum suction and test strip swabbing. After the test, the results are displayed on the detector's screen. However, the screens of most current explosives and drug detectors are directly mounted on the outside of the device. When used outdoors or in strong light, the screen is prone to glare, making the test results difficult to see. This greatly affects the detection work and the user experience. Moreover, the suction port used for vacuum suction is not easy to adjust, especially when detecting in relatively narrow spaces. Due to the large size of the detector, it is difficult to penetrate these areas, which also affects the detection work. Therefore, there is still room for improvement. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a portable drug and explosives detector, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: A portable drug and explosive detector, comprising a detector body, a handle, a display screen, and a test strip detection port arranged sequentially from one side to the other on the outer surface of the detector body, and a suction and detection assembly at the end of the detector body, a damping rotating shaft located outside the display screen on the detector body, and a cover plate rotatably connected to the outside of the detector body through the damping rotating shaft, with protective plates on both sides of the cover plate, and a storage groove adapted to the protective plates being slidably installed inside the storage groove of the detector body;

[0008] The suction and detection assembly includes an outer suction tube and an inner suction tube. A connecting component is provided between the outer suction tube and the detector body. The inner suction tube is inserted into and slides inside the outer suction tube, and a fixing component is provided between the inner suction tube and the outer suction tube.

[0009] Optionally, the protective plate is fan-shaped, and the fan-shaped axis of the protective plate coincides with the detection port.

[0010] Optionally, the connecting assembly includes an installation port, a fixing cap, and an annular shoulder fixed to the outside of the suction probe tube. The installation port is tubular and has the same inner diameter as the inner diameter of the suction probe tube. The fixing cap is sleeved on the outside of the suction probe tube and the annular shoulder. The inner surface of the fixing cap has an internal thread, and the outer surface of the installation port has an external thread. The fixing cap is installed on the external thread of the installation port through the internal thread.

[0011] Optionally, a sealing ring is fitted around the outside of the suction probe tube, and the sealing ring is located between the annular shoulder and the mounting port.

[0012] Optionally, the outer tube of the suction probe has a hollow inner hole along the axial direction, and a circular port is provided at one end of the outer tube of the suction probe near the inner tube of the suction probe. The inner diameter of the port is the same as the outer diameter of the inner tube of the suction probe and is smaller than the inner diameter of the inner hole.

[0013] Optionally, a limiting ring is provided at one end of the inner tube of the suction probe near the outer tube of the suction probe. The limiting ring is slidably installed inside the inner hole, and the outer diameter of the limiting ring is the same as the inner diameter of the inner hole.

[0014] Optionally, the outer circular surface of the limiting ring is provided with a sealing groove, and a sliding sealing ring is sleeved inside the sealing groove.

[0015] Optionally, the fixing component includes a fastening bolt and a threaded hole opened on the outside of the suction probe outer tube. The fastening bolt is threaded into the threaded hole, and one end of the fastening bolt located in the inner hole abuts against the outer surface of the suction probe inner tube.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. After the cover is rotated upwards and opened, the side guards cooperate with the cover to form a canopy-like shielding structure above the display screen. This can block external light to a certain extent, thereby preventing the display screen from being unable to see the test results due to reflection. This makes the detector more suitable for use outdoors or in strong light environments, making the test results easier to see in strong light environments, avoiding affecting the test work, and improving the user experience to a certain extent. Moreover, the opening of the canopy-like shielding structure faces the user, so it will not obstruct the user's line of sight.

[0019] 2. The length of the suction component can be adjusted according to actual usage requirements. When encountering narrow spaces, the length of the suction component can be adjusted to detect the interior of the space, enabling the detector to handle the task of detecting in confined spaces without affecting normal detection work. Moreover, the sliding sealing ring can ensure the sealing between the outer and inner suction tubes, preventing air leakage during suction, and can also achieve quick disassembly and assembly of the outer and inner suction tubes, making the replacement of the suction component more convenient.

[0027] 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.

[0028] This utility model provides, for example Figures 1 to 4Embodiment 1 of the portable drug and explosives detector shown: The detector body 1 has a handle 2, a display screen 3 and a test strip detection port 6 arranged sequentially from one side to the other on the outer surface of the detector body 1. The end of the detector body 1 is provided with a suction and detection component. A damping shaft 13 is provided on the detector body 1 outside the display screen 3. A cover plate 4 is rotatably connected to the outside of the detector body 1 through the damping shaft 13. Both sides of the cover plate 4 are provided with protective plates 5. The protective plates 5 are fan-shaped, and the fan-shaped axis of the protective plates 5 coincides with the detection port 6. The inside of the detector body 1 is provided with a storage groove 11 that matches the protective plates 5. The protective plates 5 are slidably installed inside the storage groove 11.

[0029] Working principle: The cover plate 4 can rotate on the detector body 1 via the damping shaft 13 and can be fixed at any angle within the rotation range. By rotating and adjusting, the cover plate 4 can be directly placed on the detector body 1, thus covering the display screen 3 and achieving the purpose of protecting the display screen 3.

[0030] Furthermore, by flipping the cover plate 4 upwards and opening it, the display screen 3 can be exposed, allowing the user to view the content displayed on the display screen 3. During the upward rotation of the cover plate 4, the protective plates 5 on both sides will slide out from the storage slot 11. At this time, the protective plates 5 on both sides and the cover plate 4 together form a canopy-like shielding structure above the display screen 3, which can block external light to a certain extent, thereby preventing the display screen 3 from being unable to see the test results due to reflection. Moreover, the opening of the canopy-like shielding structure faces the user, so it will not obstruct the user's view.

[0031] This utility model provides, for example Figure 1 , Figure 2 , Figure 5 and Figure 6 The second embodiment of the portable drug and explosives detector shown: The suction and detection assembly includes an outer suction tube 8 and an inner suction tube 9. A connecting component 7 is provided between the outer suction tube 8 and the detector body 1. The inner suction tube 9 is inserted into and slides inside the outer suction tube 8, and a fixing component is provided between the inner suction tube 9 and the outer suction tube 8.

[0032] The connecting component 7 includes an installation port 701, a fixing cover 702, and an annular shoulder 704 fixed to the outside of the suction probe tube 8. The installation port 701 is tubular and its inner diameter is the same as that of the suction probe tube 8. The fixing cover 702 is sleeved on the outside of the suction probe tube 8 and the annular shoulder 704. The inner surface of the fixing cover 702 is provided with an internal thread, and the outer surface of the installation port 701 is provided with an external thread. The fixing cover 702 is installed on the external thread of the installation port 701 through the internal thread.

[0033] A sealing ring 703 is fitted around the outside of the suction probe 8, and the sealing ring 703 is located between the annular shoulder 704 and the mounting port 701;

[0034] The outer tube 8 has a hollow inner hole 801 axially formed inside, and a circular port 802 is formed at one end of the outer tube 8 near the inner tube 9. The inner diameter of the port 802 is the same as the outer diameter of the inner tube 9 and smaller than the inner diameter of the inner hole 801.

[0035] A limiting ring 901 is provided at one end of the inner tube 9 near the outer tube 8. The limiting ring 901 is slidably installed inside the inner hole 801, and the outer diameter of the limiting ring 901 is the same as the inner diameter of the inner hole 801.

[0036] The outer circular surface of the limiting ring 901 is provided with a sealing groove 902, and a sliding sealing ring 12 is fitted inside the sealing groove 902;

[0037] The fixing assembly includes a fastening bolt 10 and a threaded hole 803 opened on the outside of the suction probe outer tube 8. The fastening bolt 10 is threadedly installed in the threaded hole 803, and one end of the fastening bolt 10 located in the inner hole 801 abuts against the outer surface of the suction probe inner tube 9.

[0038] Working principle: The length of the suction assembly can be adjusted by controlling the extension and retraction of the inner suction tube 9 within the outer suction tube 8. After adjustment, the inner suction tube 9 and the outer suction tube 8 are fixed by tightening the fastening bolt 10. This achieves the purpose of adjusting the length of the suction assembly according to actual usage requirements. When encountering narrow spaces, the length of the suction assembly can be adjusted to detect the interior of the space, enabling the detector to perform the task of detecting in narrow spaces without affecting normal detection work. Moreover, the sliding sealing ring 12 ensures the sealing between the outer suction tube 8 and the inner suction tube 9.

[0039] Furthermore, by unscrewing the connecting component 7 from the mounting port 701, the outer suction tube 8 can be removed from the mounting port 701, achieving quick assembly and disassembly of the outer suction tube 8 and the inner suction tube 9, making the replacement of the suction assembly more convenient. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
