Technical Field
The invention belongs to the technical field of non-contact angle adjustment, and particularly relates to a non-contact magnetic field type angle adjustment structure and method in a closed space.
Background
When the inner structure of the closed cavity needs to be adjusted in angle, a common technical scheme is to punch holes in a cover plate of the closed cavity, so that the outer rotating structure is fixedly connected with the inner rotating structure. For some special closed cavities, such as vacuum cavities, the vacuum cavity needs to be sealed again after punching, a rubber ring is generally used for sealing, the rubber ring is compressed after sealing, so that the rotating friction force is large, the angle adjustment difficulty is large, and meanwhile, the vacuum sealing performance is greatly reduced due to the fact that an opening is additionally arranged.
Another common technical solution is to add a design circuit inside the cavity and add an electrical control component (such as a rotating motor) to perform contactless fine tuning. But for some special closed cavities, such as vacuum cavities, special expensive flange lead structures are required when cable introduction is involved. Therefore, there is a need for improvements over existing tuning structures.

Detailed Description
The invention will be further illustrated by the following description and examples, which include but are not limited to the following examples.
As shown in fig. 1, the non-contact magnetic field type angle adjusting structure in the enclosed space disclosed by the invention comprises an enclosed cavity 1 and is characterized by comprising an active adjusting fixing piece 2 fixed on the outer side of a top cover of the enclosed cavity 1, an active adjusting swivel 4 rotationally connected with the active adjusting fixing piece 2 through a screw 3, an active adjusting powerful permanent magnet 5 fixed in the active adjusting swivel 4, a passive adjusting fixing piece 6 fixed on the inner side of the top cover of the enclosed cavity 1, a compression ring 8 connected with the passive adjusting fixing piece 6 through the screw 3, a passive adjusting swivel 7 connected with the passive adjusting fixing piece 6 through the compression ring 8, a passive adjusting powerful permanent magnet 9 fixed in the passive adjusting swivel 7 and a fixed pressing block 10 fixedly connected with the passive adjusting swivel 7, wherein the active adjusting powerful permanent magnet 5 and the passive adjusting powerful permanent magnet 9 are oppositely arranged in a different pole.
In actual production and manufacture, the diameter of the pressing ring 8 is longer than the diameter of the rotating shaft 11, so that the pressing ring 8 is convenient to hang upside down when the passive adjusting swivel 7 is installed, and the passive adjusting swivel 7 is limited, so that falling is avoided.
In this embodiment, the active adjusting strong permanent magnets 5 are arranged in the same pole and the same direction to form an active adjusting magnetic moment. The passive strong permanent magnets 9 are arranged in the same pole and in the same direction, and rotate with the rotation of the active magnetic moment under the acting force of the active strong permanent magnets, so as to drive the passive adjusting swivel to rotate.
In the embodiment, a rotating shaft 11 is arranged in the middle of the active adjusting fixing piece 2, a groove structure 12 matched with the rotating shaft 11 is arranged in the middle of the active adjusting swivel 4, the active adjusting fixing piece 2 and the passive adjusting fixing piece 6 are identical in structure, and the active adjusting swivel 4 and the passive adjusting swivel 7 are identical in structure.
The specific method for realizing the non-contact magnetic field type angle adjustment comprises the following steps:
S1, when the angle of the internal part of the closed cavity 1 is regulated, the active regulation swivel 4 is rotated, so that the active regulation swivel 4 rotates around the rotating shaft 11 of the active regulation fixing piece 2, and the active regulation powerful permanent magnet 5 is driven to rotate;
s2, under the action force of the opposite pole attraction of the active adjusting strong permanent magnet 5 and the passive adjusting strong permanent magnet 9, the passive adjusting strong permanent magnet 9 rotates along with the active adjusting strong permanent magnet 5;
s3, the passive adjusting powerful permanent magnet 9 drives the passive adjusting swivel 7 to rotate around the rotating shaft 11 of the passive adjusting fixing piece 6, so that the passive adjusting swivel 7 drives the fixing pressing block 10 to rotate, a device to be adjusted connected to the fixing pressing block 10 rotates, and non-contact magnetic field type angle adjustment of the closed cavity 1 is achieved.
The invention will be further described by taking the use of the invention in a torsion-scale milliwatt laser light pressure measurement experimental instrument as an example, wherein the torsion is a physical instrument for measuring force and torque, and the traditional torsion is generally composed of a suspension wire, a cross rod and a central reflecting mirror surface. The suspension wire is usually a very thin wire with stable physical properties, has a very sensitive torsion coefficient, and can realize the measurement of tiny force and moment by being matched with an optical lever amplifying system formed by a central reflector. Historically, the most classical experimental scenarios were the measurement of coulomb force (coulomb constant), gravitational force (gravitational constant), and optical pressure, etc. That is, in this experiment, it was necessary to change the initial angle of the central mirror surface by adjusting the suspension wires in the closed cavity. When the invention is used, the suspension wire of the torsion balance can be fixed on the fixed pressing block 10 of the invention, and the angle adjustment of the central reflecting mirror surface can be realized through the invention in a non-contact way. The mode not only makes the vacuum cavity leakproofness in the light pressure measurement experimental instrument better, and angular adjustment is easier, can also reduce the cost of whole experimental instrument.
The above embodiment is only one of the preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, but all the insubstantial modifications or color changes made in the main design concept and spirit of the present invention are still consistent with the present invention, and all the technical problems to be solved are included in the scope of the present invention.
