Meter, installation timing are more convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further details with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, specific embodiment described in the utility model is a kind of readable dial type level meter, including housing
1st, gravity angle table 3, level module 4, control module 2, display module 8, the front of housing 1 are provided with gravity angle table 3, institute
State left and right sides on angle dial plate 3 and be respectively arranged with level module 4 that is vertical, horizontal, tilting 45 °；
The gravity angle table 3 includes gravity pointer 301, gravity bead 302, dial plate 303, D/A converter module, described
The gravity pointer 301 freely rotated around dial plate center is provided with dial plate 303, the lower section of gravity pointer 301 is fixedly connected with
Gravity bead 302, the metal structure on the gravity pointer 301 pass through D/A converter module with the graduated metal on dial plate 303
Corresponding electrical connection obtains electronical reading；Contrasted between electronical reading, operation is more convenient easy, and speed is faster.Certainly periodically may be used
To be corrected by the position between gravity bead, dial plate and dial reading, avoid, because ageing equipment produces error, entering one
Step reduces the probability that reading occurs extremely.
The D/A converter module and display module electrically connect with control module respectively, and the control module 2 also electrically connects
There is the bluetooth module 5 with linear accelerator communication connection.
In order to facilitate display connection status and the result of correction data, the control module 2 is also electrically connected with the He of buzzer 7
Indicator lamp 6.Bluetooth connection status can be determined by indicator lamp, can be sent by buzzer when correction data error is larger
Alarm.
In order to facilitate on installation housing to linear accelerator, it is provided with the housing 1 for adsorbing fixed fixed mount
10, the fixed mount 10 is magnet or sucker.
Angle and fixation in order to facilitate adjustment housings, the fixed mount 10 are flexibly connected with housing 1 by rotating shaft,
Lock screw is provided with lived rotating shaft also.Can not be more difficult disposable accurate fixed to 0 ° when being installed due to housing, set by this
Meter, after fixed mount being fixed into linear accelerator, housing angle is finely tuned to after 0 ° by rotating shaft, consolidated by lock screw
It is fixed, installation difficulty is reduced, reduces error.
