Description

Technical Field

[0001] The invention relates to the field of lasers, and in particular to a laser mirror frame and a laser using the laser mirror frame. Background Art

[0002] In the process of laser-related experiments and laser system construction, the mirror frame is an extremely important component. Whether the mirror frame can be flexibly adjusted and whether it can maintain a certain stability under temperature changes will directly determine the performance of the laser system. As a typical mirror frame, the flexible mirror frame has been widely used in the laser field due to its simple structure and easy adjustment.

[0003] The main components of the flexible eyeglass frame include a base, a lens mounting frame is provided on the front side of the base, a lens mounting frame is provided with a lens mounting groove, a base of the lens mounting frame is provided on the base, the left or right side of the lens mounting frame is connected to the base through a first flexible connecting part, so that the lens mounting frame can be opened and closed in the left and right directions based on the base, the base and the base are connected through a second flexible connecting part, so that the base can be adjusted in pitch, and the posture of the lens can be adjusted by setting a top screw between the base and the base and between the lens mounting frame and the base.

[0004] Existing flexible mirror frames are all square mirror frames, which are large in size in the direction perpendicular to the optical axis, which makes the spacing of the optical path larger and makes it impossible to build the mirror frame more compactly, which will result in a larger overall size of the laser and higher processing costs. Summary of the invention

[0005] The purpose of the present invention is to provide a laser mirror frame to solve the problem that the existing laser cannot be compactly built. At the same time, the purpose of the present invention is also to provide a laser using the above laser mirror frame.

[0006] In order to solve the above problems, the laser glasses frame of the present invention adopts the following technical solution: the laser glasses frame includes a glasses frame base, a lens mounting frame is arranged on the front part of the glasses frame base through a seat body, a first flexible connection portion is arranged between the lens mounting frame and the seat body, a second flexible connection portion is arranged between the seat body and the glasses frame base, and avoidance corners are arranged on the left and right sides of the front and / or the left and right sides of the rear of the glasses frame base.

[0007] Beneficial effects: The present invention is an improved invention. Specifically, the present invention sets 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 frame base of the laser frame. The so-called avoidance corners mean that the shape is shrunk at the corresponding corner positions. For example, the avoidance corners are set on the left and right sides of the front part, that is, the corners on the left and right sides of the lens mounting frame are removed. The same is true for setting avoidance 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 fixing and protection of the lens, removing them will not affect the original function of the laser frame. The avoidance corners can reduce the size of the laser frame, thereby solving the problem that the laser cannot be compactly built.

[0008] Furthermore, the lens mounting frame and the seat body are formed by machining a first slit on an arc column, the first flexible connection portion is formed by reserving a first connection wall when machining the first slit, and the arc portions on the left and right sides of the front of the arc column constitute the avoidance angle. Machining the first slit on an arc column to form the seat body and the lens mounting frame has a simple structure and convenient machining on the one hand, and can also utilize the characteristics of the column material itself to form the first flexible connection portion at the first connection wall, which has the advantages of a small deformation length and a large force, can reduce temperature deformation, can make the laser frame have a low temperature drift performance, and make the directivity of the laser more stable. The arc portions on the left and right sides of the front of the arc column constitute the avoidance angle, which has the advantages of a large avoidance range and easy molding.

[0009] Furthermore, the arc column is a circular arc column. The circular arc column has the advantage of low processing difficulty.

[0010] Furthermore, a first through hole extending along the first connecting wall is processed at one side of the first slit close to the first connecting wall, the aperture of the first through hole is larger than the width of the first slit and radially connected to the first slit. The arrangement of the first through hole is equivalent to thinning the first flexible connecting portion, and the inner wall thereof forms an arc structure, which helps to disperse stress, thereby making it have a more excellent anti-deformation property.

[0011] Furthermore, the first slit is a through slit in the axial direction of the arc column, and the first connecting wall is reserved on one side in the left-right direction. Due to the characteristics of the shape of the arc column, the width of the seat body will be greater than the width of the lens mounting frame. When the first connecting wall is arranged in the left-right direction, it is convenient to adjust the angle of the lens mounting frame by arranging an adjusting member on the seat body.

[0012] Furthermore, the arc column is formed by processing the second and third slits on a column, the second slit is a through slit in the left-right direction, the depth direction of the third slit is the front-back direction, the second flexible connection part is formed by reserving a second connection wall at the intersection of the second and third slits when processing the second and third slits, and the part of the column located at the rear side of the second slit forms a support wall. The arc column is processed and formed on the column, which has the advantages of simple structure and convenient processing. The support wall is integrally planned and formed with the lens mounting frame and the seat body, which further simplifies the processing technology of the laser 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 aperture of the second through hole is larger than the gap at the corresponding side of the second connecting wall and is radially connected thereto. The function of the second through hole is similar to that of the first through hole, which is also to reduce the thickness of the second flexible connecting portion and disperse its stress.

[0014] Furthermore, the support wall is provided with a first top screw for adjusting the pitch angle of the arc column, and the seat body is provided with a second top screw for adjusting the left and right turning angles of the lens mounting frame. The top screw is used to adjust the posture of the lens mounting frame and the arc column (ultimately still reflected in the posture of the lens mounting frame), so that infinite precision adjustment can be achieved.

[0015] Furthermore, the heads of the first top screw and the second top screw are both ball heads, which can reliably contact the corresponding wall from multiple directions and prevent scratching the corresponding wall.

[0016] The laser of the present invention adopts the following technical solutions:

[0017] A laser comprises a frame and a lens, wherein the frame comprises a frame base, a lens mounting frame is arranged at the front of the frame base through a seat, a first flexible connection portion is arranged between the lens mounting frame and the seat, a second flexible connection portion is arranged between the seat and the frame base, and avoidance corners are arranged on the left and right sides of the front and / or the left and right sides of the rear of the frame base.

For example, the avoidance corners are provided on the left and right sides of the front part, that is, the corners on the left and right sides of the lens mounting frame are removed, and the same is true for the avoidance 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 fixing and protection of the lens, removing them will not affect the original function of the laser frame, and the avoidance corners can reduce the size of the laser frame, thereby solving the problem that the laser cannot be compactly built.

[0019] Furthermore, the lens mounting frame and the seat body are formed by machining a first slit on an arc column, the first flexible connection portion is formed by reserving a first connection wall when machining the first slit, and the arc portions on the left and right sides of the front of the arc column constitute the avoidance angle.

DETAILED DESCRIPTION

[0034] Flexible mirror frames are used for lasers to install laser lenses. Since the laser emission has a high directivity requirement, and the processing and assembly errors of the lenses and laser mirror frames are inevitable, the laser mirror frame is required to have a certain degree of adjustability, that is, after the lens is installed, the direction of the lens needs to be adjusted to meet the requirement that the laser is emitted in the set direction.

[0035] The main components of the flexible frame include a frame base, on which a lens mounting frame 101, a seat 102, a support wall 103 and a connecting seat 104 are arranged. The lens mounting frame 101 is provided with a lens mounting groove 11 for mounting a lens, and the seat 102 serves as the base of the lens mounting frame 101 and is used to hold the lens mounting frame 101. A flexible connection portion is arranged between the lens mounting frame 101, and the flexible connection portion has a certain elasticity. Through the deformation of the flexible connection portion, the rotation angle of the lens mounting frame 101 relative to the seat 102 in the corresponding direction can be adjusted. For the sake of distinction, the flexible connection portion between the lens mounting frame and the seat is defined as the first flexible connection portion 105. The seat body 102 and the frame base are also connected by a flexible connection part. The flexible connection part between the seat body and the frame base is defined as the second flexible connection part 106 here. The axis around which the second flexible connection part 106 is flexibly deformed is skewed and perpendicular to the axis around which the first flexible connection part 105 is deformed. Therefore, the left and right inclination angle, up and down inclination angle, and up and down left and right inclination angle of the lens mounting frame 101 can be adjusted by the cooperation of the first and second flexible connection parts.

[0036] When the posture of the lens mounting frame 101 is adjusted by using the first flexible connection part 105 as the deformation part, the base body 102 can be used as a support, and when the posture of the base body 102 and the lens mounting frame 101 as a whole is adjusted by using the second flexible connection part 106 as the deformation part, the support wall 103 provided at the rear of the base body 102 can be used as a support. Specifically, a top screw can be provided on the base body 102 to push the lens mounting frame 101 to move around the first flexible connection part 105, and a top screw can be provided on the support wall 103 to push the base body 102 to move around the second flexible connection part 106. The reverse movement of the lens mounting frame 101 relative to the base body 102 and the reverse movement of the base body 102 relative to the support wall 103 are respectively achieved by the rebound of the first flexible connection part 105 and the second flexible connection part 106.

[0037] In order to minimize the size of the laser frame perpendicular to the optical axis, avoidance corners 12 are set on the front left and right sides of the frame base (it can also be the rear left and right sides, or the front left and right sides and the rear left and right sides). The avoidance corners 12 are set to reduce the size of the head (and / or rear) of the frame base, thereby achieving a more compact construction of the laser frame, thereby reducing the overall appearance size of the laser.

[0038] The following will describe in detail the specific embodiments of the flexible eyeglass frame of the present invention in conjunction with the accompanying drawings:

[0039] like Figure 1-4As shown, in some embodiments, the lens mounting frame 101 and the seat body 102 are formed on an arc column. Specifically, the arc column can be a circular arc column. The first slit 107 is processed on the circular arc column to form the lens mounting frame 101 and the seat body 102. The processing of the first slit 107 can be performed by a sawing machine, or a milling machine, a laser cutting machine, an electric spark cutting machine, etc. The above processing techniques are mature techniques and are not described here. As can be seen from the figure, the arc parts on the left and right sides of the front part of the circular arc column constitute the avoidance corner 12.

[0040] exist Figure 1 , 2 In the embodiments shown in , 3, and 4, the first slit 107 is a through slit in the length direction of the arc column (i.e., the up-down direction of the lens mounting frame), and a connecting wall is left on the right side of the arc column. Here, the connecting wall on the right side of the arc column is defined as the first connecting wall. The outer surface of the first connecting wall is formed by a part of the outer surface of the arc column, and the first flexible connecting portion 105 is formed by the first connecting wall. In order to disperse the stress of the first flexible connecting portion 105, Figure 1 , 2 In the embodiments shown in Figures 3 and 4, a first through hole 108 extending along the first connecting wall is processed on one side of the first slit 107 close to the first connecting wall, and the aperture of the first through hole 108 is larger than the width of the first slit 107 and is radially connected thereto. Here, "connected" means that one radial side of the through hole is open as a whole and connected to the first slit 107, or that the side of the first slit 107 close to the first through hole 108 directly extends into the first through hole.

[0041] It is important to note here that although Figure 1 , 2 In the embodiments shown in Figures 3 and 4, the arc column is a circular arc column, and a first through hole 108 is provided on the inner side of the first flexible connection portion 105. However, those skilled in the art should be able to understand that in some embodiments, it is also feasible to set the arc column as an elliptical arc column, and the first through hole 108 may also be omitted.

[0042] Combination Figure 1 , 2, 3, and 4 show that in some embodiments, the arc column is formed on a cylindrical body. Specifically, a second slit 109 is processed on the body at the rear of the seat 102. The molding process of the second slit 109 can refer to the first slit 107. The second slit 109 is a through slit in the left and right directions. A third slit 110 is processed on the body below the arc column. The molding process of the third slit 110 can refer to the first slit. The second flexible connection portion 106 is formed by a second connecting wall left between the second slit and the third slit. The portion of the body below the second slit 109 constitutes the connection seat 104 of the laser mirror frame. A second through hole 111 extending along the second connecting wall is provided on the rear side of the second connecting wall (it can also be the front side, or the front side and the rear side). The aperture of the second through hole 111 is larger than the slit at the corresponding side of the second connecting wall and is radially connected thereto. This is to disperse the stress of the second flexible connection portion 106. Although in Figure 1-4 In the embodiment shown, the rear side of the second connecting wall is provided with a second through hole 111, but in some embodiments, such as Figure 6 As shown, the second through hole 111 can also be omitted. In addition, in order to enable the second connecting wall to form an arc surface as a whole to disperse the stress, it is also possible to Figure 5 The bottom of the third slit is configured to be an arc shape convex toward the front side.

[0043] The support wall 103 is provided with a first top screw 112 for adjusting the pitch angle of the arc column, and the seat body 102 is provided with a second top screw 113 for adjusting the left and right turning angles of the lens mounting frame 101. The top screws are used to adjust the posture of the lens mounting frame 101 and the arc column (ultimately still reflected in the posture of the lens mounting frame), so that infinite precision adjustment can be achieved. The heads of the first top screw 112 and the second top screw 113 are both ball head structures.

[0044] It is important to note here that although Figure 1 , 2 In the embodiments shown in , 3, and 4, the column body is a cylindrical column body, and the arc surface at the corresponding position of the column body constitutes the avoidance corner. However, those skilled in the art should understand that in some embodiments, the column body can also be a prism (with a prism cross section), and in this case, the avoidance corner can be formed by the inclined surface at the corresponding position. In addition, although Figure 1 , 2 In the embodiments shown in Figures 3 and 4, the central axis of the first flexible connection portion is the vertical axis, and the central axis of the second flexible connection portion is the horizontal axis. However, those skilled in the art should be able to understand that in some embodiments, the directions of the central axes of the two can be interchanged. In this case, the posture of the lens can still be adjusted.
