The mounting board 110 is a mounting frame for mounting optical elements in the prior art. The mounting block 100 has a mounting hole 111 in a central region thereof, the mounting hole 111 is used for mounting an optical element, and it is worth mentioning that the optical element is mounted not directly to the mounting hole 111 but through a mounting seat, and the mounting seat of the optical element is omitted in some descriptions.

The utility model discloses an installation frame 100 increases base body 120 in the below of mounting panel 110 to further fix a position installation frame 100 through the cooperation of locating lever 300 and base body 120's locating hole 121. After the positioning rod 300 coaxially positions the mounting frame 100, the optical elements may be arranged along a common optical axis. Thus, the coaxial precision of two adjacent mounting plates 110 is ensured, and the collimation of the light path is further ensured. The positioning rod 300 is made of a hard metal material. The positioning rod 300 has the characteristics of large diameter, strong rigidity and high precision, so that the positioning effect of the positioning rod 300 can be ensured.

Furthermore, the mounting bracket 100 of the present invention further has a clamping assembly 130 in the positioning hole 121, and the clamping assembly 130 can position and fix the positioning rod 300 on the base body 120. In this way, the positioning rod 300 can be reliably fixed in the base body 120, and the positional relationship of the positioning rod 300 with respect to the mounting bracket 100 is unique. When the mounting rack 100 is connected to the adjacent mounting rack 100 through the positioning rod 300, the unique positional relationship between the positioning rod 300 and the adjacent mounting rack 100 can be ensured. Thus, the influence of the installation relationship of the positioning rod 300 on the coaxial precision of the two adjacent mounting frames 100 can be avoided, and the coaxial precision between the adjacent mounting frames 100 can be improved.

The mounting bracket 100 of the embodiment can be connected and positioned through the positioning rod 300, the problem that the alignment is poor due to the fact that the guide rod of the existing coaxial optical system is easy to deform is effectively solved, the alignment is guaranteed, the coaxial precision of the mounting bracket 100 is improved, the mounting precision of the coaxial optical system is improved, the calibration precision of a light path is improved, the stability of the light path is improved, and the calibration operation of the coaxial optical system is facilitated. Furthermore, the utility model discloses an installation frame 100 sets up base body 120 in the below of mounting panel 110, like this, can not influence the overall arrangement of mounting frame 100 top optical element behind the installation locating lever 300, makes things convenient for coaxial optical system's installation to use.

Referring to fig. 1 to 6, in an embodiment, the mounting plate 110 further has a plurality of guide holes 112 for mounting the guide bar 400, and the plurality of guide holes 112 are located on a circumferential side of the mounting hole 111. A plurality of guide holes 112 are arranged on the peripheral side of the mounting hole 111, the guide holes 112 are used for mounting the guide bar 400, and the guide bar 400 plays a role of coaxial positioning. In this way, the mounting block 100 may establish a connection relationship with an adjacent mounting block 100 through the guide 400 so that the optical elements may be arranged along a common optical axis. The coaxial optical system formed by connecting the adjacent mounting brackets 100 through the guide rod 400 is a cage optical system.

It should be noted that, in various embodiments of the present invention, the mounting frame 100 has the guiding hole 112, and of course, in other embodiments of the present invention, the guiding hole 112 may not be provided on the mounting frame 100. Alternatively, the number of the guide holes 112 may be plural to ensure high accuracy of the coaxiality between the adjacent mounting brackets 100. Illustratively, the number of each group of guide holes 112 is four, and four guide holes 112 are symmetrically distributed around the mounting hole 111. Of course, in other embodiments of the present invention, the number of the guiding holes 112 may be more, such as five, six, etc.

Because the diameter of guide arm 400 is less takes place bending deformation easily, the utility model discloses an installation frame 100 further fixes a position installation frame 100 through the cooperation of locating lever 300 and base body 120's locating hole 121, need not to reuse guide arm 400 to fix a position. Therefore, the acting force on the guide rod 400 can be reduced, the guide rod 400 is prevented from bending and deforming, the coaxial precision of two adjacent mounting plates 110 is ensured, and the collimation of the light path is further ensured. It is worth noting that the diameter of the positioning rod 300 is much larger than the diameter of the guide rod 400.

Alternatively, the diameter of the guide hole 112 is the same as the diameter of the guide rod 400. The mounting block 100 may slide along the guide rods 400 through the guide holes 112 to enable adjustment of the position of the mounting block 100. After the position of the mounting block 100 is determined, the position of the mounting block 100 on the guide rod 400 needs to be fixed. In an embodiment, the mounting plate 110 further has a first fastening hole 113, the first fastening hole is located on the periphery of the guide hole 112 and communicates with the guide hole 112, and the first fastening hole 113 is used for mounting a first fastening member, so that the end of the first fastening member abuts against the guide bar 400 to fix the guide bar 400. After the guide bar 400 is mounted in the guide hole 112, a first fastening member is mounted in the first fastening hole 113, and the first fastening member may penetrate through the first fastening hole 113 to extend into the guide hole 112 and abut against the guide bar 400. At this time, the side wall of the guide bar 400 away from the first fastening member tightly abuts against the inner wall of the guide hole 112, so that the guide bar 400 cannot slide along the guide hole 112, and the mounting block 100 is fixed. Illustratively, the first fastener member is a screw and the first fastening hole 113 is a threaded hole.

In one embodiment, the mounting block 100 further includes a base 140 disposed at the bottom of the base body 120, and the base 140 is used to increase the contact area between the base body 120 and the optical bench 200. That is, the base body 120 may be fixedly mounted to the optical platform 200 by the mount 140, so that the base body 120 is reliably mounted and fixed. Optionally, the pedestal 140 is disposed protruding with respect to the base body 120. In an embodiment of the present invention, the base 140 may protrude from at least one side of the base body 120 in the axial direction of the optical axis to increase the contact area. Of course, in other embodiments of the present invention, the base 140 may also protrude from at least one side of the base body 120 along a direction perpendicular to the axial direction of the optical axis, or the base 140 may also be a combination of the above two manners, i.e., may protrude along the axial direction and protrude along the direction perpendicular to the axial direction.

Illustratively, the base 140 is located at a side of the base body 120, such that the base body 120 and the base 140 are disposed in an L-shape. This increases the contact area between the bottom of the mounting block 100 and the optical platform 200, thereby increasing the stability of the mounting block 100 fixed to the optical platform 200. Further, the base 140 has a through hole, and the stopper 600 passes through the through hole to fasten the base 120 to the optical platform 200. It will be appreciated that the shape of the through-hole is in principle not limited, and may be circular, oblong, etc., as long as a fixed mounting of the base 200 is achieved.

Illustratively, the through hole is an oblong limiting hole 141, the base 140 passes through the limiting hole 141 through the limiting member 600 and is mounted on the optical platform 200, and the base 140 can slide along the limiting member 600 through the limiting hole 141, so that the mounting block 100 slides relative to the optical platform 200. It should be noted that the optical platform 200 has the matching holes 210 arranged in rows and columns, and the matching holes 210 are matched with the position limiter 600. After the limiting member 600 is installed in the fitting hole 210 of the optical platform 200 through the limiting hole 141, the installation of the mounting block 100 on the optical platform 200 can be achieved. The number of the limiting members 600 is two, and the position of the mounting block 100 on the optical platform 200 is limited by the two limiting members 600. The two position-limiting members 600 may be located at two ends of the oblong limiting hole 141, and at this time, the position of the mounting block 100 cannot be adjusted, as shown in fig. 6. When the two position-limiting members 600 are located in the middle region of the position-limiting hole 141, the base 140 can slide along the length direction of the position-limiting hole 141, so that the mounting block 100 slides relative to the optical platform 200 to adapt to the optical path in a parallel position, as shown in fig. 7. Optionally, the retaining member 600 is a threaded member and the mating hole 210 is a threaded hole. Of course, in other embodiments of the present invention, the limiting member 600 may also be a pin, and the fitting hole 210 is a light hole.

In one embodiment, the base 140, the base body 120, the clamping assembly 130, and the mounting plate 110 are a unitary structure. The mounting block 100 with an integrated structure can improve the stability of the mounting block 100, so that the mounting block 100 can be fixed on the optical platform 200 by directly using the limiting member 600, thereby eliminating the fitting error of the mounting block 100, improving the mounting precision, and further improving the coaxial precision between the mounting blocks 100. Of course, in other embodiments of the present invention, the base 140, the base body 120, the clamping assembly 130, and the mounting plate 110 may be separated from each other and connected by fastening members such as screws to ensure the stability and accuracy of the mounting frame 100, and facilitate the use of different scenes, so that the application range is wide.

In an embodiment, the clamping assembly 130 includes a flexible elastic sheet 131, one end of the flexible elastic sheet 131 is fixed to the inner wall of the positioning hole 121, and the other end is a free end, and the flexible elastic sheet 131 is bent along the inner wall of the positioning hole 121 and encloses with the positioning hole 121 to form an accommodating space for installing the positioning rod 300. The flexible elastic sheet 131 is arranged in an arc shape, and after the flexible elastic sheet is installed in the positioning hole 121, a certain distance exists between the free end of the flexible elastic sheet 131 and the inner wall of the positioning hole 121. That is, the accommodating space surrounded by the flexible elastic sheet 131 and the positioning hole 121 is a semi-closed structure. Thus, after the positioning rod 300 is installed in the accommodating space, the position of the flexible elastic sheet 131 can be adjusted to fix the positioning rod 300.

There is a certain space on both sides of the flexible elastic sheet 131. Alternatively, the size of the receiving space may be smaller than the cross-sectional size of the positioning rod 300. At this time, after the positioning rod 300 is installed in the accommodating space, the flexible elastic sheet 131 can be pressed outward. Thus, the positioning rod 300 can be fixed to the positioning hole 121 by the elastic force of the flexible elastic sheet 131.

Of course, the accommodation space may also be larger than or equal to the cross-sectional dimension of the positioning rod 300, and at this time, the flexible elastic sheet 131 may be tightly pushed by the external fixing member to fix the positioning rod 300. Specifically, the base body 120 further has a second fastening hole 122, the second fastening hole 122 is communicated with the positioning hole 121 and corresponds to the flexible elastic sheet 131, and the second fastening hole 122 is used for installing a second fastening member 500, so that an end of the second fastening member 500 abuts against the flexible elastic sheet 131 to press the positioning rod 300 in the flexible elastic sheet 131. After the positioning rod 300 is installed in the positioning hole 121, the second fastening piece 500 is installed in the second fastening hole 122 and passes through the second fastening hole 122 to abut against one side of the flexible elastic sheet 131 far away from the positioning rod 300, so that the flexible elastic sheet 131 deforms to press the positioning rod 300 against the inner wall of the positioning hole 121, and the positioning rod 300 is reliably fixed in the accommodating space. Alternatively, the second fastening member 500 is a screw and the second fastening hole 122 is a threaded hole.

In an embodiment, the positioning hole 121 further has at least two protrusions 1211 disposed at intervals relative to the inner wall of the flexible elastic sheet 131, and the flexible elastic sheet 131 and the protrusions 1211 are used for positioning and fixing the positioning rod 300. The boss 1211 is a rib extending in the axial direction of the positioning hole 121, and the rib protrudes toward the inside of the positioning hole 121. Thus, after the positioning rod 300 is mounted in the positioning hole 121, the positioning rod 300 abuts against the flexible elastic sheet 131 and the at least two protrusions 1211 to form multi-point positioning, so that the positioning accuracy between the positioning hole 121 and the positioning rod 300 is improved, and further, when a plurality of mounting frames 100 are mounted on the same positioning rod 300, the coaxial accuracy between the mounting frames 100 can be improved. Illustratively, the number of the protrusions 1211 is two, and the two protrusions 1211 are disposed opposite to the flexible elastic sheet 131. Of course, in other embodiments of the present invention, the number of the protruding portions 1211 may be more.

In an embodiment, the clamping assembly 130 further includes a limiting post 132, and the limiting post 132 is disposed on the base body 120 and configured to abut against the free end of the flexible resilient sheet 131 and limit the flexible resilient sheet 131. The position-limiting column 132 is used for limiting the position of the free end of the flexible elastic sheet 131, so as to prevent the flexible elastic sheet 131 from being excessively deformed. When the flexible elastic sheet 131 is in a free state, a certain distance exists between the free end of the flexible elastic sheet 131 and the limiting column 132. When the second fastening member 500 abuts against the flexible elastic sheet 131, the flexible elastic sheet 131 deforms; moreover, the second fastening member 500 gradually pushes against the flexible elastic sheet 131, and the free end of the flexible elastic sheet 131 gradually approaches the position-limiting post 132. When the free end of the flexible elastic sheet 131 abuts against the limiting post 132, the flexible elastic sheet 131 stops continuously extruding the positioning rod 300, so as to prevent the flexible elastic sheet 131 from excessively deforming. Thus, when the second fastening member 500 is separated from the flexible resilient piece 131, the flexible resilient piece 131 can be restored.

Of course, in other embodiments of the present invention, the base body 120 further has a second fastening hole 122, the second fastening hole 122 communicates with the positioning hole 121, and the second fastening hole 122 is used for installing the second fastening member 500, so that the end of the second fastening member 500 abuts against the positioning rod 300 to press the positioning rod 300 into the positioning hole 121. Specifically, after the positioning rod 300 is installed in the positioning hole 121, the second fastening piece 500 is installed in the second fastening hole 122 and penetrates through the second fastening hole 122 to abut against the outer wall of the positioning rod 300 facing one side of the second fastening hole 122, at the moment, the side wall of the positioning rod 300 far away from the second fastening piece 500 can tightly abut against the inner wall of the positioning hole 122, and the positioning rod 300 is guaranteed to be reliably fixed in the positioning hole. Alternatively, the second fastening member 500 is a screw and the second fastening hole 122 is a threaded hole.

In an embodiment, the positioning hole 121 further has at least two protrusions 1211 spaced apart from each other with respect to the inner wall of the second fastening hole 122, and the second fastening member 500 and the protrusions 1211 are used for positioning and fixing the positioning rod 300. The boss 1211 is a rib extending in the axial direction of the positioning hole 121, and the rib protrudes toward the inside of the positioning hole 121. Thus, after the positioning rod 300 is mounted in the positioning hole 121, the positioning rod 300 abuts against the end portion of the second fastening member 500 and the at least two protrusions 1211 to form multi-point positioning, so that the positioning accuracy between the positioning hole 121 and the positioning rod 300 is improved, and further, when a plurality of mounting brackets 100 are mounted on the same positioning rod 300, the coaxial accuracy between the mounting brackets 100 can be improved. Illustratively, the number of the bosses 1211 is two, and the two bosses 1211 are disposed opposite to the second fastening holes 122. Of course, in other embodiments of the present invention, the number of the protruding portions 1211 may be more.

In one embodiment, the mounting hole 111 is a threaded hole, and the mounting hole 111 is used for an optical element with an external thread. That is, the optical element can be nested in the mounting seat with external threads, and at this time, the optical element can be mounted in the mounting hole 111 through the external threads of the mounting seat, so that the optical element is mounted.

In a first embodiment of the present invention, as shown in fig. 1, the mounting block 100 can mount 1 inch of optical elements; in a second embodiment of the present invention, as shown in fig. 2, the mounting block 100 can mount 2 inches of optical elements; of course, in other embodiments of the present invention, the mounting bracket 100 can also mount optical elements with other sizes. It should be noted that, for different sizes of optical elements, the structure of the mounting frame 100 is not different, but the aperture of the mounting hole 111 and the space between the plurality of guide rods 400 are adjusted according to the size of the optical element.

In one embodiment, the mounting holes 111 are light holes. The optical element can be embedded in the mounting hole 111 through the mounting seat, so that the optical element is mounted. In order to ensure the optical element to be positioned reliably, the mounting plate 110 further has a third fastening hole 114, the third fastening hole 114 is located on the peripheral side of the mounting hole 111 and is communicated with the mounting hole 111, and the third fastening hole 114 is used for mounting a third fastening piece so that the third fastening piece can be abutted with the optical element to fix the optical element. Specifically, after the optical element is mounted in the mounting hole 111, the third fastening member is mounted in the third fastening hole 114, and extends into the mounting hole 111 through the third fastening hole 114 to abut against the optical element, so that the outer wall of the optical element, which is far away from the third fastening member, is tightly attached to the inner wall of the mounting hole 111, the optical element is accurately positioned in the mounting hole 111, and the optical axes of the optical elements in the mounting holes 111 of the plurality of mounting brackets 100 are coaxial. Illustratively, the mounting seat is a sleeve, the third fastener member is a threaded member, and the third fastener hole 114 is a threaded hole.

In one embodiment, the inner wall of the mounting hole 111 opposite to the third fastening hole 114 further has at least two protrusions 1111 arranged at intervals, and the third fastening member and the at least two protrusions 1111 are used for positioning and fastening the guide bar 400. The projection 1111 is a rib extending in the axial direction of the mounting hole 111, and the rib protrudes toward the inside of the mounting hole 111. In this way, after the optical element is mounted in the mounting hole 111 through the mounting seat, the optical element abuts against the third fastening member and the at least two protrusions 1111, so as to form multi-point positioning, thereby improving the positioning accuracy between the optical element and the mounting hole 111 and improving the coaxial accuracy between the mounting brackets 100. Illustratively, the number of the projections 1111 is two, and the two projections 1111 are disposed opposite to the third fastening hole 114. Of course, in other embodiments of the present invention, the number of the protruding portions 1111 may be more.

In a third embodiment of the present invention, as shown in fig. 3, the mounting block 100 can mount 1 inch of optical elements; in a fourth embodiment of the present invention, as shown in fig. 4, the mounting block 100 can mount 2 inches of optical elements; of course, in other embodiments of the present invention, the mounting bracket 100 can also mount optical elements with other sizes. It should be noted that, for different sizes of optical elements, the structure of the mounting frame 100 is not different, but the aperture of the mounting hole 111 and the space between the plurality of guide rods 400 are adjusted according to the size of the optical element.

It should be noted that the coaxial optical system can also use optical elements with different sizes to establish the optical path, and an adapter mount 100 is required to connect two different sizes of optical elements to each other. Specifically, the structure of the adapter mounting bracket 100 is the same as that of the mounting bracket 100 in the above embodiment, except that the adapter guide holes 112 need to be added on the peripheral sides of the mounting holes 111, and at this time, the circumscribed centers of the two types of guide holes 112 coincide with each other, but the outer diameters are different. The two kinds of guide holes 112 are adapted to guide rods 400 of two kinds of optical elements of different sizes, respectively. Thus, two different sizes of optical component mounts 100 can be mounted in the guide holes 112 of the adapter mounts 100 by the guide rods 400. Alternatively, the adapting mounting bracket 100 may be a light hole or a threaded hole.

In a fifth embodiment of the present invention, as shown in fig. 5, two sides of the adapting mounting frame 100 are the mounting frame 100 for mounting the 1-inch optical element and the mounting frame 100 for mounting the 2-inch optical element, respectively. Of course, in other embodiments of the present invention, the adapting mounting frame 100 can also be adapted to mounting frames 100 of optical elements with different sizes.

In the above five embodiments, the mounting frame 100 has the same structure, and has the mounting holes 111, the positioning holes 121, and the like, and the difference is that the form of the mounting holes 111 is different, such as threaded holes or light holes, and the aperture of the mounting holes 111 is different, and the spacing between the guide holes 112 is different, so as to adapt to optical elements with different sizes. The utility model discloses an each embodiment only describes the difference part of mounting bracket 110, and the same part is not repeated one by one.

Referring to fig. 6 to 8, the present invention further provides a coaxial optical system, comprising an optical platform 200, at least one positioning rod 300, an optical element and the mounting bracket 100 of any of the above embodiments.

The optical platform 200 has the matching holes 210 arranged in rows and columns, and the distances between the matching holes 210 are the same. This facilitates the installation and positioning of the mounting bracket 100. The same positioning rod 300 can be installed between two adjacent installation racks 100 to position the adjacent installation racks 100, and when the number of the installation racks 100 is more, one positioning rod 300 can be used for positioning, at least two positioning rods 300 can be used for positioning, and at this moment, the end parts of the two positioning rods 300 need to be installed in the installation holes 111 of the installation racks 100 in the middle area.

It is worth mentioning that when the coaxial optical system requires a small number of optical components to be mounted, the guide rod 400 may not be mounted between the mounting blocks 100. When the coaxial optical system requires a large number of optical elements to be mounted, the mounting blocks 100 may not satisfy the mounting requirements, or when the distance between two adjacent mounting blocks 100 is long in order to secure the stability of the optical path transmission, at this time, the guide rod 400 is mounted between two adjacent mounting blocks 100. It will be appreciated that the optical elements may be mounted to the guide bar 400 by mounts or multi-dimensional adjustment brackets. After the optical elements are mounted on the guide rod 400, the optical elements on the guide rod 400 and the optical elements on the mounting bracket 100 may be arranged along a common optical axis, and the optical elements on the guide rod 400 may also slide along the guide rod 400 to adjust their positions.

It is understood that the mounting frames 100 for mounting optical elements of the same size may be arranged side by side, or the mounting frames 100 for mounting optical elements of at least two sizes may be arranged side by side, and the mounting frames 100 for optical elements of two different sizes are connected by the adapter mounting frame 100.

In a sixth embodiment of the present invention, as shown in fig. 6, the number of the mounting racks 100 is five, the left two are the mounting racks 100 of 1 inch optical elements, the right two are the mounting racks 100 of 2 inch optical elements, and the middle is the mounting rack 100 for switching the 1 inch optical elements and the 2 inch optical elements.

The optical elements may be secured to the guide bar 400 by mounts or multi-dimensional adjustment brackets such that the optical elements are aligned along a common optical axis and the optical elements may be moved along the guide bar 400. The two left mounting brackets 100 and the guide rods 400 thereof are suitable for mounting 1-inch optical elements, the two right mounting brackets 100 and the guide rods 400 thereof are suitable for mounting 2-inch optical elements, and the middle mounting bracket 100 realizes the switching between the mounting bracket 100 of the 1-inch optical element and the mounting bracket 100 of the 2-inch optical element.

In the seventh embodiment of the present invention, as shown in fig. 7, the number and arrangement of the mounting frames 100 are the same as those of the sixth embodiment, except that: the limiting member 600 is mounted in the middle region of the oblong limiting hole 141 and is no longer located at the end of the oblong limiting hole 141. In this way, the projection of the optical axis on the optical platform 200 is parallel to the arrangement direction of the matching holes 210 on the optical platform 200, and the optical axis can be arbitrarily moved in the direction perpendicular to the arrangement direction, that is, in the length direction of the oblong hole, so as to adapt to different use requirements.
