[0002] The right-angle optical adjustment frame is used to adjust the spatial position (pitch and yaw) of the clamped lens. Two fixed coaxial systems are vertically transferred at both ends of the right-angle optical adjustment frame (for example, four long rods are used to fix the right-angle sides of the right-angle optical adjustment frame according to the fixed center distance, and the other end of the long rod can continue to connect the right-angle side of the new right-angle optical adjustment frame) to form a multi-level vertical transfer optical adjustment structure. During the adjustment process based on this structure, the optical elements can be arranged and moved along the common optical axis. It is suitable for applications such as complex optical experiments and precision measurements, such as Figure 1 shown.
[0003] The existing right-angle optical adjustment frame lacks a rotation adjustment mechanism and cannot make the coaxial system rotate at an angle. In actual use, if you want to add a rotation adjustment mechanism to an optical system based on an optical adjustment structure to adjust the angle of the entire optical axis, you need to add additional mechanical parts to the coaxial system that are compatible with the coaxial system and can be rotated 360 degrees, which makes the structure complex, inconvenient to disassemble and assemble, and the rotation adjustment is not flexible.

Specific implementation mode
[0020] The technical solution of the present utility model will be described in detail below in conjunction with the embodiments and the drawings.
[0021] As Figure 2-4 shown, the described 360° rotating right-angle optical adjustment bracket includes a right-angle base 1, and the plane where the hypotenuse of the right-angle base is located (the inclined plane 2) is connected to an adjustment plate. The plane where one of the right-angle sides of the right-angle base is located (the first right-angle plane 3) is connected with a rotating part 5, and uniformly arranged around the plane where the other right-angle side is located (the second right-angle plane 4) are first round holes for connecting the coaxial system 7. In the embodiment, the coaxial system 7 is four long rods with an axial pitch of 30 mm.
[0022] Assembly holes for clamping optical elements or other mechanical products are provided on the inclined plane 2, the rotating part 5, and the second right-angle plane 4 of the right-angle base, and the assembly holes communicate with each other, thereby forming a through optical path channel inside the right-angle base.
[0023] On the upper and lower planes of the right-angle base perpendicular to the first right-angle plane 3 and the second right-angle plane 4, first threaded holes 6 adapted to M4*4 recessed end set screws are vertically provided at the corresponding positions of the four first round holes. When the long rod is inserted into the first round hole, the long rod is fixed in the first round hole by screwing the M4*4 recessed end set screw into the first threaded hole 6.
[0024] The rotating part 5 includes a rotating shaft 5.1 connected to the right-angle base. The rotating shaft 5.1 is in a ring structure and is coaxial with the assembly hole on the first right-angle plane 3. The outer ring at the rear end of the rotating shaft 5.1 is fixedly connected to the assembly hole on the first right-angle plane 3 through the cooperation of concave and convex grooves. The inner ring of the rotating shaft 5.1 can fix the optical element through a snap ring. The outer ring at the front end of the rotating shaft 5.1 is provided with threads at the front end, and the rotating plate 5.2 is sleeved on the rotating shaft 5.1 through the cooperation of a lock ring 5.3 and the threads. Around the front end face 5.21 of the rotating plate 5.2, there are second round holes for connecting another set of coaxial systems 7. The way to fix the long rod of the coaxial system 7 in two adjacent second round holes is as follows: through the upper side face 5.22 and the lower side face 5.23 of the rotating plate 5.2, second threaded holes 5.24 adapted to M4*4 recessed end set screws are vertically provided at corresponding positions of these two second round holes. When the long rod is inserted into these two second round holes, the long rod is fixed in these two second round holes by screwing the M4*4 recessed end set screw tightly in the second threaded hole 5.24.
[0025] On the front end face 5.21 of the rotating plate 5.2, the fixing method of the long rod of the coaxial system 7 in another two adjacent second round holes is as follows: on the right side face 5.25 of the rotating plate 5.2 close to these two second round holes, a first cut groove and a second cut groove parallel to its front and rear end faces are provided. The first cut groove and the second cut groove penetrate through the upper and lower side faces 5.22 and 5.23, and the depths of the first cut groove and the second cut groove are approximately up to the center position of the rotating plate 5.2. The design of the first cut groove and the second cut groove divides the right side of the rotating plate 5.2 along the direction of the coaxial system 7 into three parts: a first dividing plate, a second dividing plate, and a third dividing plate. Among them, the first dividing plate is provided with a third cut groove and a fourth cut groove on the right side face 5.25 vertically and tangentially close to these two second round holes, so that each of these two second round holes forms a notch.
[0026] The design of the third cut groove and the fourth cut groove divides the first dividing plate into three parts: the upper part of the first dividing plate, the middle part of the first dividing plate, and the lower part of the first dividing plate. The upper and lower side faces 5.22 and 5.23 of the rotating plate 5.2 are respectively vertically provided with third threaded holes 5.26 adapted to M2.5*6 socket head cap screws at corresponding positions of the upper part of the first dividing plate and the lower part of the first dividing plate. The length of the M2.5*6 socket head cap screw extends to the middle part of the second dividing plate. When the long rod is inserted into these two second round holes, the long rod is fixed in these two second round holes by screwing the M2.5*6 socket head cap screw tightly in the third threaded hole 5.26 to make the upper and lower end faces of the third cut groove and the fourth cut groove fit tightly.
[0027] In the right-angle optical adjustment bracket of the present utility model, the second right-angle plane 4 of the right-angle optical adjustment bracket fixedly mounts the long rod of the coaxial system in a rigid connection manner. On the rotating member 5 on the first right-angle plane 3, the long rod of the coaxial system is fixedly mounted in a rigid (by screwing an M4*4 concave end set screw into the second threaded hole 5.24 to fix the long rod in these two second circular holes) and semi-rigid and semi-flexible connection (by screwing an M2.5*6 hexagon socket head cap screw into the third threaded hole 5.26 to make the upper and lower end faces of the third cut groove and the fourth cut groove fit tightly) manner. This semi-rigid and semi-flexible fixing method can increase the reliability of the connection.
[0028] In the above structure, the second dividing plate is provided with a fifth cut groove on the right side surface 5.25 perpendicular to the middle of the tangential rotating plate, so that the second dividing plate is divided into two parts: the upper part of the second dividing plate and the lower part of the second dividing plate. Among them, on the upper side surface of the rotating plate, a fourth threaded hole 5.27 adapted to an M2.5*22 hexagon socket head cap screw is vertically provided at a corresponding position in the upper part of the second dividing plate. By screwing an M2.5*6 hexagon socket head cap screw into the fourth threaded hole 5.27, the upper and lower end faces of the fifth cut groove are tightly combined, so as to lock the rotating plate 5.2 on the rotating shaft 5.1, thereby preventing the rotating plate 5.2 from rotating relative to the rotating shaft 5.1.
[0029] In the above structure, the design of the fifth cut groove forms a flexible locking structure between the rotating plate 5.2 and the rotating shaft 5.1, that is, when the rotating member 5 needs to rotate relative to the right-angle base 1, loosen the M2.5*6 hexagon socket head cap screw in the fourth threaded hole 5.27, so that the rotating plate 5.2 rotates around the rotating shaft 5.1. When the rotating member 5 rotates to the required angle and needs to be fixed to the right-angle base 1, then screw an M2.5*6 hexagon socket head cap screw into the fourth threaded hole 5.27 to tightly hold the rotating plate 5.2 on the rotating shaft 5.1.
[0030] As Figure 5 shown, it is a right-angle optical adjustment system for two-stage vertical transfer of a right-angle optical adjustment bracket based on 360° rotation, including two sets of right-angle optical adjustment brackets for 360° rotation, and both ends of the coaxial system are respectively fixed on the rotating members of the two. In actual application, the right-angle base of one of the 360° rotating right-angle optical adjustment brackets can be fixed, and the other 360° rotating right-angle optical adjustment bracket connected thereto can be rotated through its rotating member, and the right-angle base of the other 360° rotating right-angle optical adjustment bracket can also rotate at an angle based on its own rotating member.
[0031] As Figure 6As shown in the figure, it is a right-angle optical adjustment system with three-stage vertical transfer based on a 360° rotating right-angle optical adjustment mount, including three sets of 360° rotating right-angle optical adjustment mounts. The two right-angle planes of the middle 360° rotating right-angle optical adjustment mount are respectively connected to the other two sets of 360° rotating right-angle optical adjustment mounts (the left 360° rotating right-angle optical adjustment mount and the right 360° rotating right-angle optical adjustment mount) in a fixed form and a rotating form through a coaxial system. In actual application, the right-angle base of the middle 360° rotating right-angle optical adjustment mount can be fixed, and the left 360° rotating right-angle optical adjustment mount can be rotated through its rotating part. Figure 6 In this case, if the rotating parts of the middle 360° rotating right-angle optical adjustment mount and the left 360° rotating right-angle optical adjustment mount are connected, the coaxial system between them can be rotated through the rotating part of the middle 360° rotating right-angle optical adjustment mount, and the right-angle base of the left 360° rotating right-angle optical adjustment mount can be rotated through the rotating part of the left 360° rotating right-angle optical adjustment mount. The rotating part of the right 360° rotating right-angle optical adjustment mount can be used to rotate its own right-angle base.
