The vernier 5 is slidably disposed on the support plate 101 along the length direction of the scale 4 and is arranged facing and adjacent to the scale 4 .

[0022] Since in the rail-type illuminometer calibration device provided by the present invention, the two first roller mechanisms and the one second roller mechanism in the sliding trolley 100 are located at the three corners of the same triangle in a one-to-one correspondence, a triangle is formed to be firmly supported on the first guide rail 2 and the second guide rail 3, thereby ensuring the stability of various devices and facilities (such as a standard light source, a illuminometer to be calibrated, a probe for installing the illuminometer to be calibrated, etc.) equipped on the sliding trolley 100, and ensuring that the illuminometer calibration work can be carried out reliably and stably. In addition, the rail-type illuminometer calibration device It includes a vernier part 5, which can slide along the length direction of the scale 4 so that the first scale 41 and the second scale 51 are accurately aligned to achieve accurate positioning of the initial position of the sliding trolley 100. After the trolley moves a distance along the first guide rail 2 and the second guide rail 3 again, the distance change between the first scale 41 and the second scale 51 compared with the initial alignment position is compared, and the displacement of the sliding trolley 100 can be accurately adjusted.

Such an arrangement enables the first inclined wheel 102 and the second inclined wheel 103 to form a certain clamping friction force on the upper surface of the first guide rail 2, ensuring that the first inclined wheel 102 and the second inclined wheel 103 are more stably supported on the first guide rail 2; the second roller mechanism includes an upright wheel 104, which is supported on the second guide rail 3 and is located directly above the axis of the second guide rail 3. The axis of the second guide rail 3 is perpendicular to the axis of the second guide rail 3 and is arranged in a horizontal direction.

[0025] According to a preferred embodiment of the present application, a plurality of roller adaptation stations are provided on the support plate 101, and each roller adaptation station is optionally installed with a first roller mechanism or a second roller mechanism, so that the first roller mechanism and the second roller mechanism can be conveniently replaced as standard parts. For example, the same sliding trolley 100 is not limited to installing two first roller mechanisms and one second roller mechanism, and can also be replaced and matched. For example, three first roller mechanisms are installed. In this case, there is no need to set the limiting fixing mechanism 300 mentioned below, or when the number of one of the first roller mechanism and the second roller mechanism is insufficient, the first roller mechanism and the second roller mechanism can also be replaced with each other. However, considering the use of the vertical wheel 104 in the second roller mechanism, it is necessary to control the number of the second roller mechanisms arranged.

In fact, since the first inclined wheel 102 and the second inclined wheel 103 form a certain clamping friction force on the upper surface of the first guide rail 2, this also improves the stability of the entire sliding trolley 100 supported on the first guide rail 2 and the second guide rail 3, including improving the stability of the vertical wheel 104 supported on the second guide rail 3.
