Description

TECHNICAL FIELD

[0001] The utility model relates to colorimeter technical field, specifically, relate to a colorimeter automatic white board correction structure. BACKGROUND

[0002] The colorimeter automatic white board correction structure usually includes the following key parts. The shell: as the main part of the colorimeter, it contains the colorimeter body and other components required for correction inside; the integrating sphere: located inside the shell, used for integrating and homogenizing light to improve the accuracy of measurement, the top of the integrating sphere protrudes outward to form a viewfinder window; the end cover: fitted on the viewfinder window, with a white board fixed inside, the white board is connected with the end cover as a whole, forming a detachable correction module; the fixing device: such as a fixing rod, buckle, etc., used to fix the position of the end cover, to ensure the stability of the white board during the correction process. At the same time, these devices also facilitate the user to open and close the end cover for correction operation. The colorimeter needs to be calibrated with a white board before color measurement. The white board in some existing colorimeters is usually set separately and needs to be installed on the colorimeter every time it is used. After the color calibration is completed, it needs to be removed from the colorimeter and placed aside, which leads to the loss of the white board. Moreover, the surface of the white board is prone to dirt and dust due to long-term exposure.

[0003] The existing patent application No. CN202021521258.3 discloses a colorimeter automatic white board correction structure, which includes a shell, an integrating sphere fixedly installed inside the shell, and an end cover movably sleeved at the bottom end of the integrating sphere extending out of the shell. The bottom of the inner side of the end cover is provided with a white board. The above-mentioned scheme enables the white board to be fixedly installed on the tester through the cooperation of the end cover, the fixing rod, the connecting plate, and the fixing plate, so that the white board does not need to be removed from the colorimeter during use, which is more convenient and less likely to be lost. The cooperation of the fixing rod, the connecting plate, the spring, the buckle, the fixing plate, and the sealing seat enables the colorimeter to press and rotate the fixing rod to seal the white board inside the end cover through the cooperation of the end cover and the sealing seat, preventing external dirt and dust from adhering to the surface of the white board and affecting the correction effect of the white board on the colorimeter.

[0004] However, there are still some problems in the implementation process. Although the end cover is rotated to the position directly below the sealing seat, the movement path of the end cover is not limited during the process of upward movement of the end cover driven by the spring, which leads to the rotation displacement of the end cover. Therefore, the end cover cannot be accurately and directly covered below the sealing seat. In addition, when the end cover is covered on the sealing seat, the friction sleeve and the fixing rod are prone to downward movement due to external force, which drives the end cover to move downward, thereby reducing the sealing between the end cover and the sealing seat. Therefore, external dirt and dust are still likely to enter the end cover and adhere to the surface of the white board. Therefore, a colorimeter automatic white board correction structure is needed to solve the above-mentioned problems. The utility model discloses a content
