The working principle of the embodiment is as follows: when the instrument capable of clearly reading is used, firstly, the instrument is required to be installed, in the installed cereal grass, the connecting pipeline 3 at the bottom of the instrument main body 4 and the branch pipeline 2 on the main pipeline 1 are installed through the flange installation block 18, therefore, the whole instrument main body 4 can be detected, in the detection process, when the instrument main body 4 is read in a dark environment and a humid environment, according to the illustration in figures 1 and 6, firstly, because the whole instrument main body 4 is positioned inside the whole middle sliding cover 5 and the whole outer fixed cover 6, the middle sliding cover 5 and the outer fixed cover 6 protect the instrument main body 4, the phenomenon of serious water mist and dust can not occur on the outer surface of the whole instrument main body 4, and the whole instrument main body 4 can be ensured to be read well in the humid environment and the environment with worse environment, in the process of reading, a user only needs to open the cover plate 9 under the action of the reset rotating shaft 8 to enable the outer side of the cover plate 9 to tilt, in the process of tilting the cover plate 9, the fluorescent layer 902 in the cover plate 9 can well illuminate the whole middle sliding cover 5 and the outer fixed cover 6, and then, a worker can read the meter main body 4 by matching with the magnifier 16;
In the process of reading, when the eyesight of a user is different or the magnification of the magnifier 16 is inconvenient to use, a worker can also adjust the position of the magnifier 16, as shown in fig. 2-5, firstly, the worker needs to hold the handle 11 to make the handle 11 drive the connecting plate 10 connected with the top end of the handle to move outwards, so that the first stopper 20 on the connecting plate 10 is separated from the second stopper 21 on the instrument main body 4, then the worker drives the connecting plate 10 to move in the preformed groove 17 through the handle 11, in the process of moving the connecting plate 10, the middle sliding cover 5 is driven to move, in the process of moving the middle sliding cover 5, the magnifier 16 on the top end of the middle sliding cover is driven to move, after moving to a proper position, the outward force of the handle 11 is released, so that the first stopper 20 on the connecting plate 10 is mutually clamped with the second stopper 21 on the instrument main body 4, therefore, the position of the magnifier 16 can be well adjusted, a user can read according to own preference, and the phenomenon of reading error can not occur;
in the process of moving the middle sliding cover 5, as shown in fig. 5, the expansion plate 12 can move, and since the expansion plate 12 is connected with the inside of the sliding groove 22 through the compression spring 23, the expansion plates 12 at two sides of the connecting pipeline 3 at the bottom of the instrument main body 4 can be always in contact with the outer wall of the connecting pipeline 3, so that the effect of ensuring the sealing property inside the middle sliding cover 5 is achieved;
Finally, as shown in fig. 7, when the magnifier 16 slides to the topmost end to contact with the bristles 903 on the inner side of the cover plate 9 under the action of the middle sliding cover 5, the bristles 903 on the cover plate 9 can also well wipe the surface of the magnifier 16, so that the cleanliness of the magnifier 16 is ensured, and the magnifier can be read more accurately on the instrument body 4, thereby completing a series of work.
It is to be understood that the terms "central," "longitudinal," "lateral," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the figures to facilitate a simplified description of the present invention, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus are not to be considered as limiting the scope of the present invention.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
