Abstract
Description
Technical Field
[0001] This invention relates to the field of lasers, and in particular to a laser frame and a laser using the laser frame. Background Technology
[0002] In laser-related experiments and the construction of laser systems, the mirror frame is a crucial component. Its flexibility and stability under varying temperature conditions directly determine the performance of the laser system. Flexible mirror frames, as a typical type of frame, have been widely used in the laser field due to their simple structure and ease of adjustment.
[0003] The main components of a flexible eyeglass frame include a base, a lens mounting bracket on the front of the base with a lens mounting slot, and a base for the lens mounting bracket on the base. The left or right side of the lens mounting bracket is connected to the base via a first flexible connection, allowing the lens mounting bracket to open and close in the left and right directions based on the base. The base is connected to the base via a second flexible connection, allowing the base to be tilted. The orientation of the lens can be adjusted by setting a set screw between the base and the base and between the lens mounting bracket and the base.
[0004] Existing flexible mirror frames are all square frames, which have a large size in the direction perpendicular to the optical axis. This results in a large optical path spacing, making it impossible to build the mirror frames more compactly. This will lead to a large overall size of the laser and a high processing cost. Summary of the Invention
[0005] The purpose of this invention is to provide a laser eyeglass frame to solve the problem of existing lasers not being able to be compactly assembled. Furthermore, this invention also aims to provide a laser using the aforementioned laser eyeglass frame.
[0006] To solve the above problems, the laser eyeglass frame of the present invention adopts the following technical solution: a laser eyeglass frame, including an eyeglass frame base, a lens mounting bracket is provided at the front of the eyeglass frame base via a seat, a first flexible connection is provided between the lens mounting bracket and the seat, a second flexible connection is provided between the seat and the eyeglass frame base, and avoidance corners are provided on the left and right sides of the front part and / or the left and right sides of the rear part of the eyeglass frame base.
[0007] Beneficial Effects: This invention is an improved invention. Specifically, this invention provides avoidance corners on the left and right sides of the front part and / or the left and right sides of the rear part of the laser eyeglass frame base. Avoidance corners refer to the reduction in shape at the corresponding corner positions. For example, setting avoidance corners on the left and right sides of the front part means that the corners on the left and right sides of the lens mounting bracket are removed; the same principle applies to setting avoidance corners on the left and right sides of the rear part. Since the aforementioned left and right sides of the front part and / or the left and right sides of the rear part of the frame base do not participate in the fixation and protection of the lenses, removing them will not affect the original function of the laser eyeglass frame. The avoidance corners can reduce the size of the laser eyeglass frame, thereby solving the problem of the laser not being able to be compactly assembled.
[0008] Furthermore, the lens mounting bracket and the base are formed by machining a first gap on an arc-shaped column. The first flexible connection is formed by pre-reserving a first connecting wall during the machining of the first gap. The arc-shaped portions on the left and right sides of the front of the arc-shaped column constitute the avoidance corner. Machining a first gap on an arc-shaped column to form the base and lens mounting bracket has the advantages of simple structure and convenient processing. On the other hand, it can also utilize the characteristics of the column material itself to form a first flexible connection at the first connecting wall, which has the advantages of small deformation length and large force. It can reduce temperature deformation, enable the laser frame to have low temperature drift performance, and make the laser's pointing more stable. The arc-shaped portions on the left and right sides of the front of the arc-shaped column constitute the avoidance corner, which has the advantages of large avoidance range and easy forming.
[0009] Furthermore, the arc-shaped column is a circular arc-shaped column. Circular arc-shaped columns have the advantage of being easier to manufacture.
[0010] Furthermore, a first through hole extending along the first connecting wall is machined on the side of the first gap near the first connecting wall. The diameter of the first through hole is larger than the width of the first gap and radially connected to it. The arrangement of the first through hole is equivalent to thinning the first flexible connection portion and forming an arc-shaped structure on its inner wall, which helps to disperse stress and thus gives it superior anti-deformation properties.
[0011] Furthermore, the first gap is a through gap along the axial direction of the arc-shaped column, with a first connecting wall reserved on one side in the left-right direction. Due to the shape characteristics of the arc-shaped column, the width of the base will be greater than the width of the lens mounting bracket. When the first connecting wall is located in the left-right direction, it is convenient to adjust the angle of the lens mounting bracket by setting an adjusting member on the base.
[0012] Furthermore, the arc-shaped column is formed by machining a second and third slit on a column body. The second slit is a through slit in the left-right direction, and the third slit is in the front-back direction. The second flexible connection is formed by reserving a second connecting wall at the intersection of the second and third slits during machining. The portion of the column body located behind the second slit forms a support wall. Machining the arc-shaped column on a column body has the advantages of simple structure and convenient processing. The support wall, lens mounting frame, and base body are integrally planned and formed, which further simplifies the processing technology of the laser lens frame and improves its reliability.
[0013] Furthermore, at least one side of the second connecting wall is provided with a second through hole extending along the second connecting wall. The diameter of the second through hole is larger than the gap on the corresponding side of the second connecting wall and is radially connected to it. The function of the second through hole is similar to that of the first through hole, which is to reduce the thickness of the second flexible connection and disperse its stress.
[0014] Furthermore, the support wall is provided with a first set screw for adjusting the pitch angle of the arc-shaped column, and the base is provided with a second set screw for adjusting the left and right rotation angle of the lens mounting bracket. By adjusting the posture of the lens mounting bracket and the arc-shaped column (which ultimately manifests in the posture of the lens mounting bracket) using the set screws, stepless and precise adjustment can be achieved.
[0015] Furthermore, both the first and second setter screws have ball heads. The ball heads can reliably contact the corresponding walls from multiple directions and prevent scratching the corresponding walls.
[0016] The laser of this invention adopts the following technical solution:
[0017] A laser includes a frame and lenses. The frame includes a frame base. A lens mounting bracket is provided at the front of the frame base via a seat. A first flexible connection is provided between the lens mounting bracket and the seat. A second flexible connection is provided between the seat and the frame base. Alternating corners are provided on the left and right sides of the front part and / or the left and right sides of the rear part of the frame base.
[0018] Beneficial Effects: This invention is an improved invention. Specifically, the laser of this invention has avoidance corners on the left and right sides of the front part and / or the left and right sides of the rear part of the laser frame base. Avoidance corners mean that the shape is reduced at the corresponding corner positions. For example, avoiding corners on the left and right sides of the front part means that the corners on the left and right sides of the lens mounting bracket are removed; the same principle applies to avoiding corners on the left and right sides of the rear part. Since the left and right sides of the front part and / or the left and right sides of the rear part of the frame base do not participate in the fixation and protection of the lenses, removing them will not affect the original function of the laser frame. Avoidance corners can reduce the size of the laser frame, thereby solving the problem of the laser not being able to be compactly assembled.
[0019] Furthermore, the lens mounting bracket and the base are formed by machining a first gap on an arc-shaped column. The first flexible connection is formed by pre-reserving a first connecting wall during the machining of the first gap. The arc-shaped portions on the left and right sides of the front of the arc-shaped column constitute the avoidance corner.

The arc-shaped portions on the left and right sides of the front of the arc-shaped column constitute the avoidance corner, which has the advantages of large avoidance range and easy forming.
[0020] Furthermore, the arc-shaped column is a circular arc-shaped column. Circular arc-shaped columns have the advantage of being easier to manufacture.
[0021] Furthermore, a first through hole extending along the first connecting wall is machined on the side of the first gap near the first connecting wall. The diameter of the first through hole is larger than the width of the first gap and radially connected to it. The arrangement of the first through hole is equivalent to thinning the first flexible connection portion and forming an arc-shaped structure on its inner wall, which helps to disperse stress and thus gives it superior anti-deformation properties.
[0022] Furthermore, the first gap is a through gap along the axial direction of the arc-shaped column, with a first connecting wall reserved on one side in the left-right direction. Due to the shape characteristics of the arc-shaped column, the width of the base will be greater than the width of the lens mounting bracket. When the first connecting wall is located in the left-right direction, it is convenient to adjust the angle of the lens mounting bracket by setting an adjusting member on the base.
[0023] Furthermore, the arc-shaped column is formed by machining a second and third slit on a column body.

The support wall, lens mounting frame, and base body are integrally planned and formed, which further simplifies the processing technology of the laser lens frame and improves its reliability.
[0024] Furthermore, at least one side of the second connecting wall is provided with a second through hole extending along the second connecting wall.

Detailed Implementation
[0034] Flexible frames are used in lasers to mount the laser lenses. Because laser emission requires high directivity, and errors in the processing and assembly of lenses and laser frames are unavoidable, the laser frames must have a certain degree of adjustability. That is, after the lenses are installed, their orientation needs to be adjusted to ensure the laser is emitted in the desired direction.
[0035] The main components of the flexible eyeglass frame include a frame base, on which a lens mounting bracket 101, a base 102, a support wall 103, and a connecting seat 104 are provided. The lens mounting bracket 101 has a lens mounting groove 11 for mounting lenses. The base 102 serves as the base for holding the lens mounting bracket 101. Flexible connecting parts are provided between the lens mounting brackets 101. These flexible connecting parts have a certain elasticity, and their deformation allows adjustment of the rotation angle of the lens mounting bracket 101 relative to the base 102 in a corresponding direction. For ease of distinction, the flexible connecting part between the lens mounting bracket and the base is defined as the first flexible connecting part 105. The base 102 is also connected to the frame base via a flexible connection. Here, the flexible connection between the base and the frame base is defined as the second flexible connection 106. The axis around which the flexible deformation of the second flexible connection 106 is located is perpendicular to the axis around which the deformation of the first flexible connection 105 is located. Thus, the left-right tilt angle, up-down tilt angle, and up-down-left-right tilt angle of the lens mounting bracket 101 can be adjusted by the cooperation of the first and second flexible connections.
[0036] When adjusting the posture of the lens mounting bracket 101 using the first flexible connection 105 as the deformable part, the base 102 can be used as a support. When adjusting the posture of the base 102 and the lens mounting bracket 101 as a whole using the second flexible connection 106 as the deformable part, the support wall 103 provided at the rear of the base 102 can be used as a support. Specifically, a set screw can be provided on the base 102 to move the lens mounting bracket 101 around the first flexible connection 105, and a set screw can be provided on the support wall 103 to move the base 102 around the second flexible connection 106. The reverse movement of the lens mounting bracket 101 relative to the base 102 and the reverse movement of the base 102 relative to the support wall 103 are achieved by the springback of the first flexible connection 105 and the second flexible connection 106, respectively.
[0037] In order to minimize the size of the laser frame perpendicular to the optical axis, avoidance corners 12 are provided on the left and right sides of the front part of the frame base (or the left and right sides of the rear part, or the left and right sides of the front part and the left and right sides of the rear part). The avoidance corners 12 are provided to reduce the size of the head (and / or rear) of the frame base, thereby achieving a more compact construction of the laser frame and reducing the overall appearance size of the laser.
[0038] The following will describe in detail specific embodiments of the flexible eyeglass frame of the present invention with reference to the accompanying drawings:
[0039] like Figure 1-4As shown, in some embodiments, the lens mounting bracket 101 and the base 102 are formed on an arc-shaped column. Specifically, the arc-shaped column can be a circular arc-shaped column. A first gap 107 is machined on the circular arc-shaped column to form the lens mounting bracket 101 and the base 102. The machining of the first gap 107 can be performed using a saw, a milling machine, a laser cutting machine, an EDM machine, etc. The above-mentioned machining processes are all mature processes and will not be described in detail here. As shown in the figure, the arc-shaped portions on the left and right sides of the front part of the circular arc-shaped column constitute the avoidance corner 12.
[0040] exist Figure 1 , 2 In the embodiments shown in 3 and 4, the first gap 107 is a through gap along the length of the arc-shaped column (i.e., the vertical direction of the lens mounting bracket), and a connecting wall is provided on the right side of the arc-shaped column. This connecting wall on the right side of the arc-shaped column is defined as the first connecting wall. The outer surface of the first connecting wall is formed by a portion of the outer surface of the arc-shaped column, and the first flexible connection 105 is formed by the first connecting wall. To distribute the stress in the first flexible connection 105, in Figure 1 , 2 In the embodiments shown in 3 and 4, a first through hole 108 extending along the first connecting wall is processed on the side of the first gap 107 near the first connecting wall. The diameter of the first through hole 108 is larger than the width of the first gap 107 and is radially connected to it. Here, "connected" means that the radial side of the through hole is completely open and connected to the first gap 107, or that the side of the first gap 107 near the first through hole 108 extends directly into the first through hole.
[0041] It should be noted here that, although in Figure 1 , 2 In the embodiments shown in 3 and 4, the arc-shaped column is a circular arc-shaped column, and a first through hole 108 is provided on the inner side of the first flexible connection 105. However, those skilled in the art should understand that in some embodiments, it is also feasible to make the arc-shaped column an elliptical arc-shaped column, and the first through hole 108 can be omitted.
[0042] Combination Figure 1 , 2As can be seen from points 3 and 4, in some embodiments, the arc-shaped column is formed on a cylindrical column. Specifically, a second gap 109 is machined on the column behind the base 102. The forming process of the second gap 109 can refer to that of the first gap 107. The second gap 109 is a through gap in the left-right direction. A third gap 110 is machined on the column below the arc-shaped column. The forming process of the third gap 110 can refer to that of the first gap. The second flexible connection 106 is formed by a second connecting wall left between the second gap and the third gap. The part of the column below the second gap 109 forms the connecting seat 104 of the laser lens frame. A second through hole 111 extending along the second connecting wall is provided on the rear side (or front side, or front and rear sides) of the second connecting wall. The diameter of the second through hole 111 is larger than the gap on the corresponding side of the second connecting wall and is radially connected to it. This is to disperse the stress of the second flexible connection 106. Although in Figure 1-4 In the embodiment shown, a second through hole 111 is provided on the rear side of the second connecting wall; however, in some embodiments, such as... Figure 6 As shown, the second through hole 111 can also be omitted. Additionally, to allow the second connecting wall to form a curved surface integrally to distribute stress, it can also be as follows: Figure 5 The same embodiment is shown. The bottom of the third slit is set to an arc shape that bulges forward.
[0043] The support wall 103 is equipped with a first set screw 112 for adjusting the pitch angle of the curved column, and the seat 102 is equipped with a second set screw 113 for adjusting the left and right rotation angle of the lens mounting bracket 101. Adjusting the posture of the lens mounting bracket 101 and the curved column (ultimately reflected in the posture of the lens mounting bracket) using these set screws allows for stepless and precise adjustment. Both the first set screw 112 and the second set screw 113 have ball-head structures at their ends.
[0044] It should be noted here that, although in Figure 1 , 2 In the embodiments shown in 3 and 4, the column is cylindrical, and the curved surface at the corresponding position of the column forms a avoidance corner. However, those skilled in the art should understand that in some embodiments, the column can also be a prism (with a prismatic cross-section), in which case the avoidance corner can be formed by the inclined surface at the corresponding position. Furthermore, although in Figure 1 , 2 In the embodiments shown in 3 and 4, the central axis of the first flexible connection is a vertical axis and the central axis of the second flexible connection is a horizontal axis. However, those skilled in the art should understand that in some embodiments, the directions of the two central axes can be interchanged. In this case, the attitude of the lens can still be adjusted.
