In use, the object to be detected is placed inside the detector body, and the internal detection component is activated via the external control component to detect the object. The detection results are then displayed on the external display component. However, the protective door of these GC-MS systems has a display and control switch installed on the outside without any protective structure. These components are easily exposed to dust and are prone to accidental activation. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-3 This utility model provides a technical solution: a gas chromatography-mass spectrometry (GC-MS) instrument with auxiliary protection, including a GC-MS instrument body 1, a display screen 104, and a control knob 105. One side of the GC-MS instrument body 1 is rotatably connected to a first protective door 101 and a second protective door 102 via a hinge. The display screen 104 and the control knob 105 are respectively embedded on the outside of the first protective door 101 and the second protective door 102. A plurality of latches 103 are connected to one side of the GC-MS instrument body 1.

[0024] A mounting block 2 is installed on the side of the gas chromatograph-mass spectrometer body 1 near the hinge. A connecting shaft 201 is rotatably connected inside the mounting block 2, and one end of the connecting shaft 201 is connected to the upper protective cover 202. A lower protective cover 203 is provided on the lower side of the upper protective cover 202. A sliding groove 3 is opened inside the upper protective cover 202. A return spring 301 is elastically connected inside the sliding groove 3. The top of the return spring 301 is elastically connected to the positioning block 302. The outer side of the positioning block 302 is inserted into the sliding groove 3 and the limiting block 303 respectively. One side of the limiting block 303 is welded to the protective door 101. A magnetic block 304 is embedded in the top of the positioning block 302. A magnetic block 305 is embedded inside the limiting block 303. The magnetic properties of adjacent sides of the magnetic blocks 304 and 305 are opposite.

[0025] In practice, to facilitate the protection of the display screen 104 and control knob 105 on the outside of protective doors 101 and 102, after the gas chromatography-mass spectrometry instrument is used, the upper protective cover 202 and lower protective cover 203 are rotated through the rotating connection between the mounting block 2 and the connecting shaft 201 to cover and protect the display screen 104 and control knob 105. Then, the positioning block 302 is pushed downwards along the sliding groove 3 until it is completely placed inside the sliding groove 3. Finally, the upper protective cover 202 and lower protective cover 203 are completely flush with the surfaces of protective doors 101 and 102. After the alignment is completed, the positioning block 302 is released. At this time, the positioning block 302 can be inserted into the slot inside the limiting block 303 under the elastic action of the return spring 301 inside the sliding groove 3. At this time, the magnetic block 305 embedded inside the slot of the limiting block 303 and the magnetic block 304 embedded inside the positioning block 302 attract each other, strengthening the limiting effect of the positioning block 302 and the limiting block 303. This gas chromatograph-mass spectrometer with auxiliary protection provides auxiliary protection for the exposed parts on the outside by rotating the upper protective cover 202 and the lower protective cover 203, which is safer.

[0026] See Figures 2-5 It is known that the bottom of the upper protective cover 202 is hinged to the lower protective cover 203 via a connecting hinge 4. A guide rod 401 is welded to the outside of the upper protective cover 202. A second return spring 402 is elastically connected inside the guide rod 401. One end of the second return spring 402 is welded to the insertion rod 403. The upper side of the insertion rod 403 is inserted into the guide rod 401, and the lower side of the insertion rod 403 is welded to the lower protective cover 203. A groove 405 is provided inside the lower protective cover 203. A stop block 404 is inserted into the groove 405, and the upper side of the stop block 404 is welded to the upper protective cover 202.

[0027] In specific implementation, to facilitate convenient operation of the control knob 105 on the outside of the second protective door 102, the lower protective cover 203 is hinged to the upper protective cover 202 using a connecting hinge 4. When in use, the control knob 105 can be exposed by flipping the lower protective cover 203 open. After use, the return spring 402 inside the guide rod 401 welded to the upper protective cover 202 will push the plug rod 403 welded to the lower protective cover 203 along the groove inside the guide rod 401, thereby pushing the lower protective cover 203 to reset. At the same time, the groove 405 at the bottom of the lower protective cover 203 will be inserted into the stop block 404 welded to the bottom of the upper protective cover 202 to prevent the lower protective cover 203 from being pushed excessively. The rotational connection between the lower protective cover 203 and the upper protective cover 202 of this auxiliary protective gas chromatograph-mass spectrometer facilitates the flexible use of both.

[0028] In summary, when using this gas chromatography-mass spectrometry (GC-MS) instrument with auxiliary protection, the protective doors 101 and 102 are opened by locking 103. After placing the object to be tested inside the GC-MS instrument body 1, the protective doors 101 and 102 are closed. The positioning block 302 is pushed down along the sliding groove 3. The upper protective cover 202 and lower protective cover 203 are rotated open by the mounting block 2 and the connecting shaft 201. The detection components inside the GC-MS instrument body 1 can then be controlled by the control knob 105 to detect the object to be tested. The final detection results are then displayed on the display screen 104. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
