[0030] refer to Figure 2-4 , shows a lifting guide bracket with a double-track structure, comprising a base plate 2, a guide column 1 arranged on the base plate 2 and a baffle 3 arranged on the top of the guide column 1, wherein the guide column 1 is a square column; guide bars 11 are arranged at the four corners of the guide column 1 along the length direction, and an angle of 90° is formed between two adjacent guide bars 11. Taking the cross section of the guide column 1 as a reference, first supporting surfaces 111 are formed on the two side surfaces of the guide bar 11 and are parallel to each other, and second supporting surfaces 112 are formed on the ends of the guide bar 11 and are perpendicular to each other, and an angle of 45° is formed between the first supporting surface 111 and the corresponding side surface on the guide column 1, and the second supporting surface 112 is parallel to the corresponding side surface on the guide column 1, and the two adjacent guide bars 11 form a first guide rail structure; two parallel guide grooves 12 are arranged on each side surface of the guide column 1, and the two inner walls of the guide groove 12 are convexly provided with limiting convex edges 121, and the two guide grooves 12 on the side surface of the guide column 1 form a second guide structure.

[0031] Specifically, in order to reflect the advantages of the lifting guide bracket, the following is an embodiment of the lifting guide bracket cooperating with two structures of the carrier. For the convenience of description, the carrier with a dovetail groove structure is defined as a first carrier 100, and the carrier that slides using a slider 210 and a bolt is defined as a second carrier 200;

[0032] like Figure 5 and Figure 6 As shown, the cooperation between the first carrier 100 and the lifting guide bracket is shown. Figure 6 The first carrier 100 has a dovetail groove structure, the first carrier 100 cooperates with the two guide bars 11 on the guide column 1, the first support surface 111 on the guide bar 11 cooperates with the inner wall inclined surface of the dovetail groove structure of the first carrier 100, and the first support surface 111 on one side of the guide bar 11 cooperates with the bottom surface of the dovetail groove structure; Figure 6 A first locking bolt 140 is threadedly connected to the side surface of the first carrier 100 , and the end of the first locking bolt 140 abuts against the first supporting surface 111 of the guide bar 11 to fix the first carrier 100 on the guide column 1 .

[0033] like Figure 5 and Figure 7 As shown, another cooperation between the first carrier 100 and the lifting guide bracket is shown, wherein: Figure 7 The first carrier 100 and Figure 6 The first carrier 100 in the embodiment is a carrier with a dovetail groove structure, the difference is that: Figure 7 The first stage 100 in Figure 6 The width of the dovetail groove structure of the first carrier 100 can be adjusted; specifically, refer to Figure 7 The first carrier 100 is composed of a first component 110 and a second component 120. Some structural features of the dovetail groove structure are located on the first component 110, and other structural features of the dovetail groove structure are located on the second component 120. The first component 110 and the second component 120 are connected by an adjusting bolt 130. The relative position between the first component 110 and the second component 120 is adjusted by adjusting the adjusting bolt 130, thereby adjusting the width of the dovetail groove structure to achieve the fixation of the first carrier 100 on the guide column 1.

[0034] It should be noted that Figure 6 and Figure 7 The purpose of the first carrier 100 is to illustrate that the guide bar 11 can cooperate with a variety of carriers with dovetail groove structures.

[0035] like Figure 8 and Fig. 9 As shown, the cooperation between the second carrier 200 and the lifting guide bracket is shown. The second carrier 200 is not guided and slidable by a dovetail groove structure. Fig. 9A second locking bolt 220 is passed through the second carrier 200, and the second locking bolt 220 is inserted into the guide groove 12 on the guide column 1 and is threadedly connected with a slider 210. The slider 210 is slidably set in the guide groove 12. When the second locking bolt 220 is tightened, the nut of the second locking bolt 220 and the slider 210 clamp the second carrier 200 on the side of the guide column 1 to fix the second carrier 200 on the guide column 1. Conversely, when the second locking bolt 220 is loosened, the second carrier 200 can slide on the guide column 1.

[0036] In this way, the lifting guide bracket is integrated with a first guide rail structure and a second guide rail structure. The first guide rail structure can slide with a carrier with a dovetail groove through two guide bars 11, and the second guide rail structure can slide with another carrier through two guide grooves 12. The lifting guide bracket is more versatile and can adapt to carriers of two structures, which facilitates the layout of the optical test system.

[0037] In some embodiments, to prevent the carrier from being separated from the guide column 1, refer to Figure 2 , the vertical projection range of the guide column 1 is located within the vertical projection range of the baffle 3; in this way, the baffle 3 blocks the guide path of the first guide structure and the second guide structure to prevent the carrier from detaching from the guide column 1 from above.

[0038] In some embodiments, for ease of installation, reference Figure 3 The lower end surface of the guide column 1 is provided with a plurality of first connection holes 14, and the bottom plate 2 is provided with a second connection hole 21, and the first connection hole 14 and the second connection hole 21 are connected by bolts (not shown); the upper end surface of the guide column 1 is provided with a plurality of third connection holes 15, and the baffle 3 is provided with a fourth connection hole 31, and the third connection hole 15 and the fourth connection hole 31 are connected by bolts (not shown). In this way, the bottom plate 2, the guide column 1 and the baffle 3 are detachably connected, so that one of the components can be easily replaced separately.

[0039] Specifically, in order to facilitate fixing the bottom plate 2 to the workbench (optical test platform), a mounting hole 22 is further provided on the bottom plate 2 .

[0040] In some embodiments, in order to reduce the weight of the guide column 1 and reduce the manufacturing cost, Figure 4 A hollow channel 13 is provided in the guide column 1.

[0041] Specifically, the guide column 1 and the guide bar 11 are an integrated structure, and the guide column 1 is made of AL7075 aluminum alloy, so that the guide column 1 has good corrosion resistance and mechanical properties.

[0042] 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.
