Technical Field

[0001] The present application relates to the technical field of gas analyzers, and more specifically, to a combined and detachable infrared gas analyzer protective housing. Background Art

[0002] An infrared gas analyzer is a device that uses infrared rays to analyze gases. It is based on the different concentrations of the components to be analyzed and the different absorbed radiation energies. The remaining radiation energy causes the temperature in the detector to rise differently, resulting in different pressures on both sides of the moving film, thereby generating an electrical signal of a capacitive detector. In this way, the concentration of the components to be analyzed can be indirectly measured.

[0003] After searching the publication number: CN212748724U, an infrared gas analyzer is disclosed, including a main body and a support assembly; the main body includes a guide sleeve, a slide rod, a first locking member and an analyzer body. The support assembly includes a first fixed block, a support foot, a fixed plate, a fixed frame, a threaded rod, a rotating member, a threaded sleeve and a connecting rod; when in use, the rotating member drives the threaded rod to rotate, so that the threaded sleeve moves up and down in the cavity, and the threaded sleeve drives the two fixed plates to move relative to each other through the connecting rod, and the fixed plate drives the support feet at both ends to move, so as to adjust the support angle, and then, loosen the first locking member, slide the slide rod, and adjust the analyzer body to a suitable height according to the situation of the measurement point; the utility model can adjust the height and support angle of the analyzer, enhance the stability of the instrument placement, and has strong adaptability to the environment.

[0032] Example:

[0033] The present application embodiment discloses a combined detachable infrared gas analyzer protective housing. Figure 1 and Figure 2 , comprising a supporting device 1, a mounting plate 2 is mounted on the top of the supporting device 1, and an analyzer connecting component 3 and a protection component 4 are respectively arranged on the top of the mounting plate 2;

[0034] See also Figure 3 The analyzer connection assembly 3 includes an analyzer body 31 arranged on the top of the mounting plate 2, and a card slot 32 is provided on both sides of the outside of the analyzer body 31. Two symmetrical fixing plates 33 are installed on the top of the mounting plate 2. A sliding rod 34 is connected to the inside of the fixing plate 33. A card plate 35 is installed at one end of the sliding rod 34, and a pull plate 36 is installed at the other end of the sliding rod 34. The card plate 35 and the card slot 32 are a card-engaging structure. A spring 37 is installed on one side of the outside of the fixing plate 33 and located outside the sliding rod 34. One end of the spring 37 is connected to the card plate 35, and a pull ring 38 is installed on one side of the outside of the pull plate 36.

[0035] The pull ring 38 is provided to facilitate the user to pull the pull plate 36, and the card plate 35 and the card slot 32 are in a snap-fit ​​structure. When the card plate 35 is located inside the card slot 32, the analyzer body 31 can be successfully installed.

[0036] See also Figure 4 and Figure 5 The protection component 4 includes a mounting seat 41 arranged at both ends of the top of the mounting plate 2, a motor 42 is installed at the bottom end of the inner part of the mounting seat 41, a screw rod 43 is connected to the power driving end of the motor 42, and the connection between the screw rod 43 and the mounting seat 41 is movably connected through a bearing, and a moving seat 44 is connected to the outside of the screw rod 43, and slide plates 45 are installed on both sides of the outer side of the moving seat 44, and slide grooves 46 are opened on both sides of the inner part of the mounting seat 41, and the slide plate 45 is located inside the slide groove 46 and is a sliding connection structure, and a protective shell 47 is installed on the outer side of the two moving seats 44, and the protective shell 47 is located outside the analyzer body 31;

[0037] The movable seat 44 is located inside the mounting seat 41 through the arrangement of the slide plate 45 and the slide groove 46 for linear movement; the motor 42 rotates for a certain period of time and then rotates in the opposite direction (it can be set by programming, which is a known technology and will not be described in detail here).

[0038] The implementation principle of this embodiment is as follows: when the analyzer body 31 is not in use, it needs to be protected. At this time, the user only needs to start the two motors 42 at the same time, so that the two motors 42 drive the screw rod 43 to rotate. At this time, the moving seat 44 is located inside the mounting seat 41 through the setting of the slide plate 45 and the slide groove 46 to move linearly. The two moving seats 44 jointly drive the protective shell 47 to move downward until the lower surface of the protective shell 47 is in contact with the upper surface of the mounting plate 2, and the protective shell 47 can protect the analyzer body 31; when using the analyzer body 31, the user only needs to start the motor 42 again, so that the power drive end of the motor 42 drives the screw rod 43 to rotate in the opposite direction, until the two moving seats 44 jointly drive the protective shell 47 to move upward, and when the analyzer body 31 is completely leaked, the analyzer body 31 can be used; this structure is convenient for protecting the analyzer body 31 and improving the service life of the analyzer body 31;

[0039] After the analyzer body 31 has been used for a long time, when the analyzer body 31 needs to be disassembled later, the protective shell 47 is first located at the highest point, and then the user holds the pull ring 38 to drive the pull plate 36 to pull outward, so that the pull plate 36 drives the card plate 35 to move through the slide bar 34, and the card plate 35 squeezes the spring 37. At this time, the card plate 35 is separated from the card slot 32 opened on the outside of the analyzer body 31. When both card plates 35 are separated from the inside of the card slot 32, the analyzer body 31 can be disassembled from the top of the mounting plate 2; when the analyzer body 31 is installed later, the user only needs to hold the pull ring 38 to drive the pull plate 36 to move outward, so that the card plate 35 squeezes the spring 37, and then the analyzer body 31 is located at the top of the mounting plate 2, and the position of the card slot 32 corresponds to the position of the card plate 35, and then the pull plate 36 is released to drive the card plate 35 to reset and rebound forward through the setting of the spring 37. At this time, the card plate 35 is located inside the card slot 32, and the analyzer body 31 can be successfully installed on the top of the mounting plate 2.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
