DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Combine the following Figures 1 to 9 An optical frame of the present invention is described.

[0037] like Figure 1 to Figure 2 As shown, this embodiment provides an optical frame, including: a base 100 , a claw clamp 200 and an adjustment component 300 .

[0038] The claw clamp 200 is rotatably connected to the base 100; there are multiple claw clamps 200, and the multiple claw clamps 200 are arranged along the circumference of the base 100, and a clamping opening is formed between the multiple claw clamps 200. The adjustment component 300 is arranged on the base 100, and the adjustment component 300 is respectively connected to the multiple claw clamps 200, and can drive the multiple claw clamps 200 to rotate to adjust the size of the clamping opening.

[0039] In practical applications, one end of the claw 200 or the middle of the claw 200 can be rotatably connected to the base 100 through the hinge 400. To ensure the reliability of the clamping opening to clamp the optical lens 500, at least three claws 200 can be provided, and at least three claws 200 are evenly distributed on the base 100 along the circumference.

[0040] At the same time, in this embodiment, the adjusting assembly 300 can be used to drive each claw pliers 200 to rotate relative to the base 100 by a preset angle in the same rotation direction to adjust the size of the clamping opening.

[0041] For example, the adjustment component 300 can drive each claw 200 to rotate clockwise at a preset angle relative to the base 100 to control the diameter of the clamping opening to decrease by a preset value; the adjustment component 300 can also drive each claw 200 to rotate counterclockwise at a preset angle relative to the base 100 to control the diameter of the clamping opening to increase by a preset value. The claws 200 can rotate synchronously or asynchronously, which is not specifically limited.

[0042] In addition, the adjustment assembly 300 of this embodiment may include a plurality of telescopic driving mechanisms, and each of the telescopic driving mechanisms may be used to drive each of the claws 200 to rotate relative to the base 100 to adjust the size of the clamping opening.

[0043] The adjustment assembly 300 may also include a rotary drive member and a linkage member, which are connected to each other. When the rotary drive member rotates, the linkage member drives each claw clamp 200 to rotate synchronously in the same direction relative to the base 100 to adjust the size of the clamping opening.

[0044] Of course, the adjustment component 300 can also be set to other structural forms, which will not be described in detail here.

[0045] As can be seen from the above, by setting an adjustment component 300 and a plurality of claws 200 on the base 100, each claw 200 can be driven to rotate relative to the base 100 based on the adjustment component 300, so that the size of the clamping opening can be adjusted to achieve the fixation of optical devices of different sizes. It has a simple structure and is easy to operate. Compared with traditional fixed-size optical frames, it reduces design investment costs, saves design time, and improves work efficiency.

[0046] It should be noted that the optical device includes an optical lens, an aperture, an optical detection device, etc. Since the optical lens 500 is widely used in the optical field, the following embodiments mainly take the fixing of the optical lens 500 as an example to specifically illustrate the solution of the present invention.

[0047] The clamping opening shown in this embodiment is suitable for clamping a circular optical lens 500. When the optical lens 500 is a reflector, since the light beam is directly reflected to other optical devices by the reflector after irradiating the surface of the reflector, there is no need to set a light opening on the base 100.

[0048] When the optical lens 500 is a focusing lens, a dichroic mirror or other lens, since the light beam needs to pass through the optical lens 500, the present embodiment sets a light opening 101 on the base 100, and a plurality of claws 200 are arranged around the light opening 101 so that the clamping opening is opposite to the light opening 101. Therefore, the present embodiment can clamp the optical lens 500 without affecting the normal use of the optical lens 500.

[0049] like Figure 3 As shown, when the optical frame clamps the small-sized optical lens 500, the adjustment component 300 can be used to drive each claw 200 to rotate synchronously counterclockwise at a first angle relative to the base 100, so that the diameter of the clamping opening reaches the first diameter, thereby achieving the fixation of the small-sized optical lens 500. The diameter of the optical lens 500 is smaller than the diameter of the light-through opening 101.

[0050] like Figure 4 As shown, when the optical frame clamps the large-sized optical lens 500, the adjustment component 300 can be used to drive each claw 200 to rotate synchronously counterclockwise at a second angle relative to the base 100, so that the diameter of the clamping opening reaches the second diameter, thereby achieving the fixation of the large-sized optical lens 500. The second angle is greater than the first angle, the second diameter is greater than the first diameter, and the diameter of the optical lens 500 is greater than the diameter of the light-through opening 101.

[0051] In some embodiments, Figure 3 , Figure 4 , Figure 7 and Fig. 9 As shown, in order to conveniently adjust the size of the clamping opening, the adjustment assembly 300 of this embodiment includes an adjustment member 31; the adjustment member 31 includes an adjustment ring 311 and a plurality of guide posts 312, and the adjustment ring 311 is rotatably disposed on the base 100; the adjustment ring 311 is connected to one end of the plurality of guide posts 312.

[0052] The base 100 is provided with a plurality of arc holes 102, which are arranged along a circle, and a plurality of guide posts 312 are respectively passed through the plurality of arc holes 102; a plurality of claws 200 are respectively arranged opposite to the plurality of arc holes 102, and each claw 200 is provided with a strip hole 201, and one end of the guide post 312 away from the adjustment ring 311 is passed through the strip hole 201.

[0053] In this way, when clamping the optical lens 500, by controlling the adjustment ring 311 to rotate relative to the base 100, the guide columns 312 on the adjustment ring 311 can drive the claws 200 to rotate synchronously along the same rotation direction to adjust the size of the clamping opening, and the operation is simple and convenient.

[0054] It should be noted that when the light opening 101 is provided on the base 100 , the plurality of arc holes 102 are evenly distributed around the center of the light opening 101 , and the plurality of claws 200 are evenly distributed around the center of the light opening 101 .

[0055] Furthermore, if Figure 5As shown, the base 100 shown in this embodiment includes: a supporting portion 11, a mounting portion 12 and a sleeve portion 13; the supporting portion 11, the mounting portion 12 and the sleeve portion 13 are connected in sequence, and the sleeve portion 13 is arranged on one side of the mounting portion 12.

[0056] The adjusting ring 311 is rotatably sleeved on the peripheral wall of the sleeve portion 13 . A plurality of arc-shaped holes 102 are respectively provided on the mounting portion 12 . The claw forceps 200 are rotatably disposed on a side of the mounting portion 12 away from the sleeve portion 13 .

[0057] Specifically, a mounting hole is provided at the bottom end of the support portion 11 so as to fix the base 100 to the bottom plate through the mounting hole. The mounting portion 12 is provided at the top end of the support portion 11, the mounting portion 12 and the sleeve portion 13 are coaxially arranged along the first axis, and the light port 101 passes through the mounting portion 12 and the sleeve portion 13 along the direction of the first axis.

[0058] In this embodiment, three arc holes 102 can be constructed on the mounting portion 12, and the three arc holes 102 are evenly distributed around the center of the light opening 101. Accordingly, three claws 200 are provided, and the three claws 200 are arranged opposite to the three arc holes 102 one by one.

[0059] A hinge 400 is provided on the side of the mounting portion 12 away from the sleeve portion 13, and the center radial distance of the hinge 400 relative to the light opening 101 is greater than the center radial distance of the arc hole 102 relative to the light opening 101. The claw 200 is rotatably mounted on the hinge 400. The hinge 400 may be a locking screw or a pin known in the art.

[0060] In some embodiments, Figure 1 , Figure 5 and Figure 8 As shown, the sleeve connection portion 13 shown in this embodiment includes: a polished rod segment 131 and a threaded segment 132 ; one end of the polished rod segment 131 is connected to the mounting portion 12 , and the other end of the polished rod segment 131 is connected to one end of the threaded segment 132 .

[0061] The adjustment assembly 300 further includes a pressing ring 32; an adjusting ring 311 is rotatably sleeved on the peripheral wall of the polished rod section 131; the pressing ring 32 and the threaded section 132 are threadedly connected through an internal thread structure and an external thread structure; and the adjusting ring 311 is clamped between the pressing ring 32 and the mounting portion 12. When the pressing ring is tightened, the pressing ring can drive the adjusting ring to rotate, so that the clamping opening is reduced to tighten the optical device.

[0062] The internal thread structure is arranged on the inner side surface of the pressing ring 32 , and the external thread structure is arranged on the side surface of the thread segment 132 .

[0063] When fixing the optical lens 500, the adjusting ring 311 can be sleeved on the polished rod section 131, so that the guide column 312 passes through the arc hole 102 and the bar hole 201 on the claw pliers 200 in sequence; then, the pressing ring 32 is installed on the threaded section 132; then, according to the diameter of the optical lens 500, the rotation angle of the adjusting ring 311 relative to the base 100 is controlled to adjust the size of the clamping opening; after the clamping opening is initially fixed to the optical lens 500, the pressing ring 32 can be rotated to move toward the adjusting ring 31 along the sleeve portion 13 1, after the pressure ring 32 and the opposite end faces of the adjusting ring 311 are fitted, under the action of the contact friction between the pressure ring 32 and the adjusting ring 311, during the process of tightening the pressure ring 32, the pressure ring 32 will continue to move toward the adjusting ring 311 along the sleeve portion 13, and fasten the adjusting ring 311 to the mounting portion 12, and the pressure ring 32 can also drive the adjusting ring 311 to rotate, so that each guide column 312 drives each claw clamp 200 to rotate relative to the base 100, resulting in a reduction in the clamping opening, so as to tighten the optical device again, thereby ensuring the fastening effect of the optical device.

[0064] Obviously, when tightening the adjustment ring 311 , the rotation direction of the pressure ring 32 should be consistent with the rotation direction of the adjustment ring 311 when clamping the optical lens 500 , so as to ensure the reliability of the claw 200 clamping the optical lens 500 .

[0065] In some examples, in addition to using the pressure ring 32 to tighten the adjustment ring 311, this embodiment can also open a screw hole on the outer circumference of the adjustment ring 311, and then install a locking screw into the screw hole to fix the adjustment ring 311 to the sleeve portion 13 through the locking screw.

[0066] Of course, other methods may also be used to fix the adjustment ring 311, which will not be described in detail here.

[0067] In some embodiments, Figure 5 , Figure 7 and Figure 8 As shown, in this embodiment, a side surface of the adjustment ring 311 facing the mounting portion 12 is set as a first smooth surface P1, and a side surface of the mounting portion 12 facing the adjustment ring 311 is set as a second smooth surface P2, and the first smooth surface P1 and the second smooth surface P2 are in contact with each other. In this way, based on the cooperation between the first smooth surface P1 and the second smooth surface P2, the contact friction force when the adjustment ring 311 rotates relative to the mounting portion 12 can be reduced.

[0068] At the same time, the side of the pressing ring 32 of this embodiment facing the adjusting ring 311 is set as the first friction surface Q1, and the side of the adjusting ring 311 facing the pressing ring 32 is set as the second friction surface Q2, and the first friction surface Q1 and the second friction surface Q2 are in contact. In this way, based on the cooperation of the first friction surface Q1 and the second friction surface Q2, the contact friction between the pressing ring 32 and the adjusting ring 311 can be increased, so that in the process of tightening and fixing the pressing ring 32, it is convenient to drive the adjusting ring 311 to rotate in the same direction through the pressing ring 32, and while gradually tightening the adjusting ring 311, it can also ensure that the claw pliers 200 tightly clamp the optical lens 500.

[0069] Wherein, both the first friction surface Q1 and the second friction surface Q2 can be rough surfaces with fine stripes or fine particle layers.

[0070] In some embodiments, Figure 5 As shown, in this embodiment, the diameter of the polished rod segment 131 is greater than the diameter of the threaded segment 132 , so that a limiting step is formed between the polished rod segment 131 and the threaded segment 132 .

[0071] In this way, this embodiment can limit the axial movement of the pressure ring 32 in the threaded section 132 based on the limiting step. When tightening the optical lens 500, it can prevent the adjustment ring 311 from rotating at an angle exceeding a preset value driven by the pressure ring 32, thereby avoiding the claw clamp 200 from clamping and damaging the optical lens 500. When disassembling and assembling the optical lens 500, it is convenient to control the reverse rotation of the pressure ring 32, thereby improving the convenience of disassembling and assembling the optical lens 500.

[0072] In some embodiments, Figure 7 As shown, in order to facilitate manual control of the adjustment ring 311 to rotate relative to the sleeve portion 13 , the outer side surface of the adjustment ring 311 shown in this embodiment is provided with a toothed structure 3111 , and the toothed structure 3111 extends along the circumference of the adjustment ring 311 .

[0073] The tooth structure 3111 includes a plurality of tooth grooves, and the plurality of tooth grooves are arranged along a circumference relative to the central axis of the adjustment ring 311 .

[0074] In some embodiments, Figure 1 and Fig. 9 As shown, the claw forceps 200 of this embodiment include: a base portion 21 and a protrusion 22 ; the protrusion 22 is arranged on a side of the base portion 21 away from the base 100 .

[0075] When the optical device is clamped by the clamping opening, the side surface of the protrusion 22 is used to abut against the peripheral wall of the optical device, and the side surface of the base portion 21 facing away from the base 100 is used to fit against the end surface of the optical device.

[0076] In this way, in this embodiment, by configuring the claw forceps 200 to include a base portion 21 and a protruding portion 22 , the reliability of clamping the optical device can be ensured through the contact and cooperation between the base portion 21 and the protruding portion 22 and the optical device.

[0077] In some embodiments, Figure 1 and Fig. 9 As shown, in order to increase the adjustment margin of the clamping opening, the first end of the claw pliers 200 is rotatably connected to the base 100 in this embodiment; the strip hole 201 extends from the first end of the claw pliers 200 to the second end of the claw pliers 200. The strip hole 201 extends along the length direction of the claw pliers 200.

[0078] Specifically, the first end of the claw forceps 200 shown in this embodiment is provided with a hinge hole 202, and the hinge hole 202 is rotatably mounted on the hinge 400, and the hinge 400 is fixedly connected to the base 100, so that the first end of the claw forceps 200 is rotatably mounted on the base 100 through the hinge 400.

[0079] Meanwhile, the protrusion 22 shown in this embodiment is disposed in the middle of the base 21, so that the base 21 has a skirt protruding from the side of the protrusion 22. In the thickness direction of the claw pliers 200, the hinge hole 202 and the hinge hole 202 penetrate the base 21 and the protrusion 22 respectively.

[0080] In this way, when the optical lens 500 is clamped, the side of the skirt facing away from the base 100 is supported by the end face of the optical lens 500, and the peripheral wall of the optical lens 500 abuts against the side of the protrusion 22.

[0081] As can be seen from the above, the optical frame of this embodiment includes: a base 100, an adjustment member 31, a pressure ring 32 and a claw clamp 200; by rotating the adjustment ring 311 on the adjustment member 31, the claw clamp 200 can be driven to rotate relative to the base 100 based on the guide column 312 on the adjustment ring 311, so as to control the increase or decrease of the clamping opening, so that optical lenses 500 of different diameters can be clamped through the clamping opening, and finally the pressure ring 32 is used to tighten the adjustment ring 311 to achieve the purpose of fixing and clamping the optical lens 500.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
