Description

Technical Field

[0001] This application relates to the technical field of VOCs detectors, and in particular to a portable VOCs detector. Background Technology

[0002] VOCs are volatile organic compounds, referring to organic compounds with a saturated vapor pressure greater than 133.32 Pa at room temperature and a boiling point between 50 and 260 °C at normal pressure, or any volatile organic solid or liquid at room temperature and pressure, including toluene, ethylbenzene, styrene, formaldehyde, ethanol, tetradecane, TVOC, etc.

[0003] Most existing VOCs detectors are directly exposed to the outside environment without any protection for the detection probe. Furthermore, since the detection probe is a separate long rod, if the VOCs detector falls to the ground, it will directly collide with the ground, causing damage to the probe and affecting its subsequent use. To address these issues, a portable VOCs detector is proposed. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a portable VOCs detector.

[0005] This application provides a portable VOCs detector, which adopts the following technical solution: A portable VOCs detector includes a first protective shell, a VOCs detector is fixedly connected inside the first protective shell, a detection probe is provided on the surface of the VOCs detector, a second protective shell is provided on one side of the first protective shell, a fixing rod is fixedly connected to the bottom of the first protective shell, a guide rod is slidably connected inside the fixing rod, the guide rod is fixedly connected to the second protective shell, and a threaded rod is rotatably connected to the surface of the fixing rod.

[0006] By adopting the above technical solution, the VOCs detector is encased by the first and second protective shells, thus preventing the detection probes from being exposed to the outside world and protecting the detection probes.

[0007] Optionally, the threaded rod extends through the interior of the fixed rod, and the surface of the threaded rod located inside the fixed rod is connected to the internal thread of the guide rod.

[0008] By adopting the above technical solution, the guide rod is controlled by rotating the threaded rod, thereby driving the separation of the first protective shell and the second protective shell, so that the VOCs detector can be used normally.

[0009] Optionally, a carrying handle is fixedly connected to the surface of the first protective shell, a limiting rod is fixedly connected to the surface of the first protective shell, a movable rod is slidably connected inside the limiting rod, and the movable rod is fixedly connected to the second protective shell.

[0010] By adopting the above technical solution, the sliding of the second protective shell is guided by the setting of the limiting rod and the moving rod.

[0011] Optionally, a limiting plate is fixedly connected inside the second protective shell, and a limiting groove is formed on the surface of the limiting plate, with the surface of the detection probe in contact with the inner wall of the limiting groove.

[0012] By adopting the above technical solution, the detection probe can be fixed by setting the limiting plate and limiting groove, which avoids the detection probe from swinging and shaking when the VOCs detector is moved, thus preventing damage from contact.

[0013] Optionally, a cover plate is rotatably connected inside the first protective shell, and a positioning groove is provided on the side of the cover plate near the second protective shell. A positioning rod is fixedly connected to the side of the second protective shell near the cover plate, and the surface of the positioning rod is slidably connected to the inner wall of the positioning groove.

[0014] By adopting the above technical solution, and through the setting of positioning rod and positioning groove, the cover plate is locked when the second protective shell and the first protective shell are close together, thereby protecting the VOCs detector inside the first protective shell.

[0015] Optionally, a torsion spring is movably sleeved on the mounting shaft surface of the cover plate, and the two ends of the torsion spring are fixedly connected to the cover plate and the first protective shell, respectively.

[0016] By adopting the above technical solution, the VOCs detector is protected by a cover plate, which further reduces the possibility of damage to the VOCs detector. At the same time, the torsion spring allows the VOCs detector to be directly exposed to the outside world after the first protective shell is separated from the second protective shell, so that it can be used by operators.

[0017] Optionally, a mounting rod is fixedly connected inside the second protective shell, and a wiping cloth is installed inside the mounting rod.

[0018] By adopting the above technical solution, the screen of the VOCs detector is cleaned by wiping with a wiping cloth.

[0019] Optionally, a rubber pad is provided on the side of the second protective shell close to the first protective shell, and the rubber pad is in contact with the first protective shell.

[0020] By adopting the above technical solution, the gap between the first and second protective shells is filled by setting rubber pads, thereby reducing the possibility of water ingress into the equipment and further protecting the equipment.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. This utility model encloses the VOCs detector by setting up a first protective shell and a second protective shell, thereby avoiding the situation where the detection probes are exposed to the outside world, protecting the detection probes, and fixing the detection probes, preventing the detection probes from swaying or shaking when the VOCs detector is moved, which could lead to damage from contact.

[0023] 2. This utility model controls the movement of the second protective shell to separate from the first protective shell, allowing the positioning rod to move out of the positioning groove without obstructing the cover plate. With the cooperation of the torsion spring, the cover plate automatically flips open, allowing the VOCs detector to be used. When the second protective shell approaches the first protective shell, it presses the cover plate, making the positioning groove parallel to the positioning rod. As the second and first protective shells approach each other, the positioning rod inserts into the positioning groove and locks the cover plate. This prevents the VOCs detector buttons from being exposed to the air, thus preventing dust, oil, and other contaminants from seeping into the VOCs detector and polluting its circuit board, thereby protecting the VOCs detector.

[0024] 3. This utility model controls the movement of the second protective shell, which in turn moves the wiping cloth and the mounting rod. The wiping cloth then moves to wipe the screen of the VOCs detector, thereby reducing the amount of dust and oil adhering to the screen. This reduces the accelerated aging of the VOCs detector screen due to dust or oil, thus protecting the VOCs detector screen and providing further protection for the VOCs detector.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a portable VOCs detector. It includes a first protective shell 1, with a VOCs detector 9 fixedly connected inside the first protective shell 1. A detection probe 11 is disposed on the surface of the VOCs detector 9. A second protective shell 2 is disposed on one side of the first protective shell 1. A fixed rod 7 is fixedly connected to the bottom of the first protective shell 1. A guide rod 8 is slidably connected inside the fixed rod 7 and fixedly connected to the second protective shell 2. A threaded rod 4 is rotatably connected to the surface of the fixed rod 7, penetrating into the interior of the fixed rod 7. The surface of the threaded rod 4 inside the fixed rod 7 is threadedly connected to the interior of the guide rod 8. Therefore, by rotating the threaded rod 4, and due to the obstruction of the fixed rod 7, the guide rod 8 does not rotate with the threaded rod 4 but slides with the rotation of the threaded rod 4. Thus, by rotating the threaded rod 4, the guide rod 8 is controlled.

[0033] Please see Figure 1 A carrying handle 18 is fixedly connected to the surface of the first protective shell 1. The carrying handle 18 makes it easy for staff to hold and carry the equipment. A limiting rod 5 is fixedly connected to the surface of the first protective shell 1. A moving rod 6 is slidably connected inside the limiting rod 5. The moving rod 6 is fixedly connected to the second protective shell 2. The limiting rod 5 and the moving rod 6 guide the sliding of the second protective shell 2.

[0034] Please see Figure 3 The second protective shell 2 is internally fixedly connected to a limiting plate 12. A limiting groove 13 is formed on the surface of the limiting plate 12. The surface of the detection probe 11 contacts the inner wall of the limiting groove 13. The limiting plate 12 and the limiting groove 13 support the detection probe 11, thereby reducing the swinging of the detection probe 11 when the device moves, and further reducing the possibility of damage to the detection probe 11, thus protecting the detection probe 11.

[0035] Please see Figure 4The first protective shell 1 is rotatably connected to a cover plate 3. The cover plate 3 has a positioning groove 16 on the side near the second protective shell 2. The second protective shell 2 is fixedly connected to a positioning rod 17 on the side near the cover plate 3. The surface of the positioning rod 17 is slidably connected to the inner wall of the positioning groove 16. Thus, by setting the positioning rod 17 and the positioning groove 16, when the second protective shell 2 and the first protective shell 1 are close together, the cover plate 3 is locked, thus protecting the VOCs detector 9 inside the first protective shell 1.

[0036] Please see Figure 3 A torsion spring 10 is movably sleeved on the mounting shaft surface of the cover plate 3. The two ends of the torsion spring 10 are fixedly connected to the cover plate 3 and the first protective shell 1, respectively. When the cover plate 3 closes the first protective shell 1, the torsion spring 10 is in a twisted state.

[0037] Please see Figure 4 The second protective shell 2 is fixedly connected to the inside of the mounting rod 14, and the inside of the mounting rod 14 is equipped with a wiping cloth 15. The screen of the VOCs detector 9 is wiped and cleaned by wiping the screen with the wiping cloth 15.

[0038] Please see Figure 4 A rubber pad is provided on the side of the second protective shell 2 that is close to the first protective shell 1. The rubber pad is in contact with the first protective shell 1. The rubber pad fills the gap between the first protective shell 1 and the second protective shell 2, thereby reducing the possibility of water entering the equipment and further protecting the equipment.

[0039] The implementation principle of a portable VOCs detector according to an embodiment of this application is as follows: When the VOCs detector 9 needs to be used, the user rotates the threaded rod 4. The rotation of the threaded rod 4 drives the guide rod 8. Due to the obstruction of the fixed rod 7, the guide rod 8 does not rotate with the threaded rod 4, but slides with the rotation of the threaded rod 4. At this time, the guide rod 8 drives the second protective shell 2 to move. The second protective shell 2 drives the wiping cloth 15 and the mounting rod 14 to move. The wiping cloth 15 moves to clean the VOCs detector 9, and the second protective shell 2 drives the limiting plate 12 to move. The movement of the limiting plate 12 no longer restricts the detection probe 11, and at the same time, the second protective shell 2 no longer covers the detection probe 11, so that the detection probe 11 is exposed to the outside for use. When the VOCs detector 9 is no longer used, the threaded rod 4 is rotated again. The threaded rod 4 drives the guide rod 8, and the guide rod 8 drives the second protective shell 2 to move. The movement of the second protective shell 2 covers and obstructs the VOCs detector 9 again.

[0040] When the second protective shell 2 moves and separates from the first protective shell 1, the second protective shell 2 drives the positioning rod 17 to move. The positioning rod 17 moves out of the positioning groove 16 and no longer obstructs the cover plate 3. Under the torque of the torsion spring 10, the cover plate 3 automatically flips open, so that the VOCs detector 9 can be used. When the second protective shell 2 moves closer to the first protective shell 1, it presses the cover plate 3, so that the positioning groove 16 is parallel to the positioning rod 17. As the second protective shell 2 and the first protective shell 1 move closer, the positioning rod 17 inserts into the positioning groove 16 to lock the cover plate 3.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
