Description

Technical Field

[0001] This utility model relates to the field of optical technology, and in particular to a continuously adjustable optical axis adjustment mechanism. Background Technology

[0002] During the use of the load, it is sometimes necessary to adjust the optical axis at a small angle. Existing methods often involve adding shims at the installation position to create a height difference, thereby achieving the purpose of adjusting the pitch and roll angles of the load.

[0003] However, in the existing methods mentioned above, adding gaskets requires a lot of time and manpower, and the load needs to be frequently disassembled and reassembled, making it impossible to achieve continuous adjustability and difficult to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a continuously adjustable optical axis adjustment mechanism, which aims to solve the problems in the prior art where adding shims requires a lot of time and manpower, frequent disassembly and assembly of the load, and the inability to achieve continuous adjustment, as well as the technical problems of difficult operation.

[0005] To achieve the above objectives, this utility model employs a continuously adjustable optical axis adjustment mechanism, comprising a mounting base, two sets of support members, two fixing screws, a pitch adjustment seat, two pitch adjustment screws, a column, a load mounting seat, two roll adjustment screws, a large screw, and multiple small screws. Both sets of support members are fixedly mounted above the mounting base. Each set of support members is provided with a fixing screw. The pitch adjustment seat is connected to each of the two fixing screws. The two pitch adjustment screws are movably connected to the pitch adjustment seat and pass through it. The column is fixedly connected to the pitch adjustment seat and located above it. The column has multiple movable holes. The multiple small screws are connected to the load mounting seat and pass through the corresponding movable holes. The large screw is connected to the load mounting seat and movably passes through the column. The two roll adjustment screws are movably connected to the load mounting seat and pass through it.

[0006] The support includes a support base and two support bolts. The support base is located above the mounting base. Both support bolts are movably connected to the mounting base and pass through the support base. The fixing screw is movably connected to the pitch adjustment seat and passes through the support base.

[0007] The continuously adjustable optical axis adjustment mechanism further includes multiple connecting bolts, which movably pass through the mounting base and are evenly distributed circumferentially on the mounting base.

[0008] The ends of the two pitch adjustment screws and the two roll adjustment screws are all smooth curved surfaces.

[0009] This utility model discloses a continuously adjustable optical axis adjustment mechanism. During operation, first, the fixing screws on the support member are turned to loosen the pitch adjustment seat above the mounting base. Then, the two pitch adjustment screws on the pitch adjustment seat are adjusted to extend the length of the pitch adjustment seat. The height difference between the protruding parts of the two pitch adjustment screws is used to adjust the load pitch angle. After reaching the desired pitch angle, the pitch adjustment screws are tightened to fix the pitch angle. Finally, the fixing screws on the two support members are tightened to complete the adjustment and fixing of the pitch angle. Similarly, first loosen the multiple small screws between the column and the load mounting base. The large screw serves as the roll axis. By adjusting the roll adjustment screw on the load mounting base, the length of the load mounting base is increased. The roll angle of the load is adjusted by the height difference between the protruding parts of the two roll adjustment screws. After reaching the desired roll angle, tighten the small screws to complete the adjustment and fixation of the roll angle. In this way, the optical axis pitch and roll angle of the load can be conveniently and continuously adjusted without frequent disassembly and assembly of the load. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please see Figures 1-12This utility model provides a continuously adjustable optical axis adjustment mechanism, including a mounting base 101, two sets of support members, two fixing screws 104, a pitch adjustment seat 105, two pitch adjustment screws 106, a column 107, a load mounting seat 108, two roll adjustment screws 109, a large screw 110, and multiple small screws 111. Both sets of support members are fixedly mounted above the mounting base 101. Each set of support members is provided with a fixing screw 104. The pitch adjustment seat 105 is connected to two fixing screws 104, and the two pitch adjustment screws 106 are connected to the pitch adjustment seat 107. The adjustment seat 105 is movably connected and passes through the pitch adjustment seat 105. The column 107 is fixedly connected to the pitch adjustment seat 105 and is located above the pitch adjustment seat 105. The column 107 has multiple movable holes 114. Multiple small screws 111 are connected to the load mounting seat 108 and pass through the corresponding movable holes 114. The large screw 110 is connected to the load mounting seat 108 and movably passes through the column 107. Two roll adjustment screws 109 are movably connected to the load mounting seat 108 and pass through the load mounting seat 108.

[0026] In this embodiment, during operation, firstly, the fixing screws 104 on the support are turned to loosen the pitch adjustment seat 105 above the mounting base 101. Then, the two pitch adjustment screws 106 on the pitch adjustment seat 105 are adjusted to protrude from the length of the pitch adjustment seat 105. The height difference between the protruding parts of the two pitch adjustment screws 106 is used to adjust the load pitch angle. After the desired pitch angle is reached, the pitch adjustment screws 106 are tightened to fix the pitch angle. Then, the fixing screws 104 on the two support members are tightened to complete the adjustment and fixing of the pitch angle. Similarly, first loosen the multiple small screws 111 between the column 107 and the load mounting base 108. The large screw 110 serves as the roll motion axis. By adjusting the roll adjustment screw 109 on the load mounting base 108, the length of the load mounting base 108 is increased. The roll angle of the load is adjusted by the height difference between the protruding parts of the two roll adjustment screws 109. After reaching the desired roll angle, the small screws 111 are locked to complete the adjustment and fixation of the roll angle. In this way, continuous adjustment can be achieved during the adjustment of the pitch angle and roll angle, which improves the accuracy of the optical axis adjustment. Compared with the method of adding shims, the operation is more convenient, and there is no need to frequently disassemble and assemble the load. Apart from using tools, no additional materials are needed during the adjustment process.

[0027] Furthermore, the support includes a support base 102 and two support bolts 103. The support base 102 is located above the mounting base 101. Both support bolts 103 are movably connected to the mounting base 101 and pass through the support base 102. The fixing screw 104 is movably connected to the pitch adjustment seat 105 and passes through the support base 102.

[0028] In this embodiment, the support base 102 is fixed above the mounting base 101 by the support bolt 103. The support base 102 can be easily removed from the mounting base 101 by turning the support bolt 103. The operation is simple. The fixing screw 104 is the movement axis of the pitch adjustment seat 105.

[0029] Furthermore, the continuously adjustable optical axis adjustment mechanism also includes a plurality of connecting bolts 112, which movably pass through the mounting base 101 and are evenly distributed circumferentially on the mounting base 101.

[0030] In this embodiment, by providing a plurality of connecting bolts 112 on the mounting base 101, the mechanism can be securely fixed on the base using the plurality of connecting bolts 112.

[0031] Furthermore, the ends of both pitch adjustment screws 106 and both roll adjustment screws 109 have smooth curved surfaces 113.

[0032] In this embodiment, by providing the ends of the pitch adjustment screw 106 and the roll adjustment screw 109 with the smooth curved surface 113, the smooth curved surface 113 being a spherical surface, the screw can maintain continuous and smooth sliding with the contact surface, which is beneficial for adjustment.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
