In conclusion, the sliding plate 501, the fixture block 502, the base 402, the adjusting block 6 and other structures are matched, so that the measurement port 3, the blackboard and the whiteboard can be quickly calibrated, and the blackboard and the whiteboard are close to the measurement port 3 to form fit correspondence during calibration, so that the gap can be avoided, and the correction accuracy of the measurement port 3 can be improved; because the blackboard and the white board are finally close to the measuring port 3, the abrasion of the blackboard and the white board can be effectively reduced, and the service life is prolonged. Overall structure is compact, combines blackboard and blank and casing 2 and color meter body 1 to form the integration together, can effectively reduce holistic occupation space to when casing 2 was accomodate to blackboard and blank, can effectively reduce blackboard and blank and be infected with the possibility that the dust made dirty. Can also take in the casing 2 with measuring port 3 after finishing using and form the laminating with the blackboard and correspond, and then saved and assembled the protective sheath for measuring port 3, accomodate in casing 2 because of blackboard and blank simultaneously, also saved and assembled the protective sheath for blackboard and blank, and then practiced thrift working cost greatly, holistic practicality is higher.
Example two:
referring to fig. 1 to 6, on the basis of the first embodiment, in order to further reduce the possibility of dust contamination of the blackboard and the whiteboard, the sliding plate 501 includes a bottom plate 5011 fixedly connected to the fixture block 502 and an attaching member 7 in up-and-down sliding fit with the bottom plate 5011, the attaching member 7 is in the same sliding direction with the measuring port 3 based on the bottom plate 5011, and at the same time, the side of the attaching member away from the bottom plate 5011 is in an attaching state with the inner bottom wall of the housing 2, and the blackboard (whiteboard) is mounted on the bottom plate 5011. When the bottom plate 5011 moves towards the measuring port 3 along with the fixture block 502, so that the blackboard (whiteboard) and the measuring port 3 are attached and correspond to each other, the attachment assembly 7 can block the opening 201 exposed from the housing 2 after the measuring port 3 is retracted, and the opening 201, i.e., the housing 2, is provided for the sliding of the measuring port 3.
Referring to fig. 1 to 7, in the present embodiment, it is preferable that: the attaching assembly 7 includes a ferrule 701 slidably engaged with the bottom plate 5011, a plurality of third springs 702 are fixedly mounted between the top of the ferrule 701 and the bottom plate 5011, and the ferrule 701 tends to move away from the bottom plate 5011 under the action of the third springs 702.
Further, to ensure that the ferrule 701 forms a complete circle at the bottom of the base 5011 and completely cover the opening 201, the bottom of the mating base 5011 forms a seal for the opening 201, and the sliding fit between the bracket 504 and the base 5011 requires the bracket 504 to be offset from the ferrule 701. Meanwhile, an annular groove 5012 is formed at the bottom of the bottom plate 5011 and used for slidably arranging the ferrule 701.
