For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0029] refer to Figure 1 and Figure 2 , shows a guide rail plate with a double-type rail structure, including a bottom plate 1 and a main body 2 arranged on the bottom plate 1, the main body 2 is provided with a first guide rail structure 3 and a second guide rail mechanism; the first guide rail structure 3 includes two guide bars 31 obliquely arranged on both sides of the main body 2, the guide bar 31 has a support limit surface 311 located at the top and a side limit surface 312 located at the side, the support limit surface 311 is horizontally arranged and protrudes from the top surface of the main body 2, and the side limit surface 312 is vertically arranged and protrudes from the side surface of the main body 2; the second guide rail structure 4 includes two parallel guide grooves 41 opened on the top surface of the main body 2, the two guide grooves 41 are located between the two guide bars 31, and the two inner walls of the guide groove 41 are protruding with limit convex edges 411.

[0030] Among them, the guide plate is integrated with a first guide structure 3 and a second guide structure 4. The first guide structure 3 can slide with a carrier with a dovetail groove through two guide bars 31, and the second guide structure 4 can slide with another carrier through two guide grooves 41. The guide plate has higher versatility and can adapt to carriers of two structures, which facilitates the layout of the optical test system.

[0031] In some embodiments, in order to reduce the weight of the guide rail plate and reduce the manufacturing cost, reference Figure 3 The main body 2 is provided with hollow holes 21 arranged along its length direction. In this way, the consumables of the main body 2 are reduced.

[0032] In the above scheme, in order to facilitate the fixing and installation of the guide plate on the optical platform, refer to Figure 1 The bottom plate 1 is provided with a strip-shaped mounting hole 11. Thus, a threaded fastener such as a bolt can be passed through the mounting hole 11 to press the bottom plate 1 onto the optical platform. The mounting hole 11 is strip-shaped, so that the position of the guide plate on the optical platform can be adjusted by slightly loosening the bolt, without completely removing the bolt, which is convenient for operation.

[0033] In the above solution, the bottom plate 1, the main body 2 and the guide bar 31 are an integrated structure, and the guide rail plate is made of AL7075 aluminum alloy, so that the guide rail plate has good corrosion resistance and mechanical properties.

[0034] In order to demonstrate the advantages of the guide rail plate, the following is an embodiment of the guide rail plate cooperating with two structures of carriers. For the convenience of description, the two structures of carriers are respectively defined as a first carrier 100 and a second carrier 200.

[0035] like Figure 4 and Figure 5As shown, the guide rail plate cooperates with the first carrier 100. The first carrier 100 is a carrier with a dovetail groove (not marked in the figure) at the bottom. This type of carrier is a carrier with a common structure in an optical test system. The dovetail groove at the bottom of the first carrier 100 is slidably arranged on the guide rail plate. Specifically, the two guide bars 31 are respectively matched with the two inner side walls of the dovetail groove of the first carrier 100. The supporting limiting surface 311 on the guide bar 31 supports the bottom surface of the dovetail groove. The side limiting surface 312 on the guide bar 31 corresponds to the inner side wall of the dovetail groove. The first platform 100 is fixed by a first bolt 110 which is threadedly connected to the side of the first platform 100. When the first bolt 110 is loosened, the first bolt 110 does not contact the side limiting surface 312 on the guide bar 31, and the first platform 100 can slide along the guide rail plate. After the position of the first platform 100 is adjusted, the first bolt 110 can be tightened so that the end of the first bolt 110 abuts against the side limiting surface 312 on the guide bar 31, thereby fixing the first platform 100 on the guide rail plate.

[0036] like Figure 6 and Figure 7 As shown, the guide plate cooperates with the second carrier 200, and the second carrier 200 has a through hole (not marked in the figure), and a second bolt 210 is arranged in the through hole, and the second bolt 210 is inserted into the guide groove 41 on the guide plate, and a slider 220 is arranged in the guide groove 41, and the slider 220 is threadedly connected with the second bolt 210; wherein, when it is necessary to fix the position of the second carrier 200 on the guide plate, the second bolt 210 can be tightened, and the slider 220 will move along the axial direction of the second bolt 210 and approach the second carrier 200, and under the blocking of the slider 220 by the limiting convex edge 411, the nut of the second bolt 210 and the slider 220 will clamp the second carrier 200 on the top surface of the main body 2; conversely, the second bolt 210 can be loosened, and the slider 220 will move away from the second carrier 200, at this time, the second carrier 200 can be made to slide on the guide plate to adjust the position of the second carrier 200.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
