[0002] When doing optical experiments in laboratories and corporate R&D rooms, it is often necessary to use a lens holder to fix the lens. One of the current universal mirror frames is that two mounting plates are connected by the end of a bolt to a smaller joint bearing. The aperture of the joint bearing generally matches an M4 or M6 bolt. Then a spring is set at the mounting plate away from the bolt. The frame is adjusted by turning the bolt and then using the elastic force of the spring. However, the adjustment effect is mainly based on the spring.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0022] The purpose of the present invention is to provide a universal mirror frame to solve the problems existing in the prior art, and to provide a wider range of adjustment and stable adjustment.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-Figure 2As shown, the present invention provides a universal mirror frame, including a joint bearing 3 and two mounting plates arranged opposite to each other, the joint bearing 3 is arranged between the two mounting plates, and the inner ring body and the outer ring body of the joint bearing 3 are respectively fixedly connected to the two mounting plates, one of the mounting plates is used to fix the optical element, the inner hole of the ring body arranged on this mounting plate is used to install the optical element, and the outer side wall of the optical element fits the side wall of the inner hole. The caliber of the joint bearing matches the diameter of the optical element, which is generally larger than the existing M4 and M6 caliber joint bearings 3. During the adjustment process, only one end of the two mounting plates needs to be manipulated to move closer or farther from each other. Since the size of the joint bearing 3 is large, the adjustment range is large, and the two mounting plates are adjusted according to needs, there is no mutation point, and the adjustment is stable.

[0025] It should be noted that the inner ring size of the joint bearing 3 used in this embodiment is 30 mm and the outer ring size is 47 mm, which can ensure a larger adjustment range. In production and use, the size of the joint bearing 3 to be used can be determined according to needs. For larger optical elements or those that require a larger adjustment range, a larger joint bearing 3 can be used.

[0026] In some embodiments, the two mounting plates are respectively a second mounting plate 1 and a first mounting plate 2, the first mounting plate 2 is used to fix the optical element, the first mounting plate 2 is fixedly connected to the outer ring body of the joint bearing 3, and the second mounting plate 1 is fixedly connected to the inner ring body of the joint bearing 3. The inner and outer ring bodies are respectively connected to different mounting plates, and the mounting plates and the joint bearing 3 cooperate and restrict each other. When performing operations such as angle adjustment, it is not easy to loosen or shake, thereby ensuring the stability of the overall structure of the universal mirror frame.

[0027] The second mounting plate 1 is in the shape of a stepped shaft, and the intermediate shaft with a smaller diameter is fixedly connected to the inner hole side wall of the inner ring body of the spherical bearing 3. There is a height difference between the inner ring body and the outer ring body of the spherical bearing 3, and the outer ring body is fixedly connected to the first mounting plate.

[0028] It should be noted that the second mounting plate 1 may be connected to the outer ring body, and the first mounting plate 2 may be connected to the inner ring body, and the first mounting plate 2 may be used to fix the optical element.

[0029] In some embodiments, two oppositely disposed retaining rings 4 are fixedly disposed on the second mounting plate 1, and the two retaining rings 4 are fixedly disposed on the side wall of the outer ring body, and the optical element is clamped between the two retaining rings 4. A through hole for accommodating the outer ring body is disposed on the second mounting plate 1, and the retaining ring 4 can be screwed into the threaded hole of the second mounting plate 1 by threading, and the specification of the threaded hole is an SM1 threaded hole. Using the retaining ring 4 to fix the optical element avoids pasting or threaded connection, etc., is more convenient for installation and disassembly, and has less damage to the optical element, and the two retaining rings 4 can be matched with the side wall of the SM1 threaded hole to achieve good fixation of the optical element.

[0030] In some embodiments, the universal mirror frame further includes a threaded adjustment device 5, which includes a stud 501 and a nut 502. The nut 502 is fixedly disposed on the edge of the first mounting plate 2. The stud 501 is threadedly connected to the nut 502, and the first end of the stud 501 abuts against the second mounting plate 1, and the second end extends out of the first mounting plate 2. The first mounting plate 2 is in the shape of a spliced ​​structure of a semi-cylinder and a rectangular parallelepiped, the rectangular parallelepiped is spliced ​​on the plane side of the semi-cylinder, the shape of the second mounting plate 1 is similar to that of the first mounting plate 2, and the threaded adjustment device 5 is disposed on the rectangular parallelepiped. By adjusting the threaded adjustment device 5, the rectangular parallelepiped sides of the second mounting plate 1 and the first mounting plate 2 can be brought closer to or farther from each other, thereby bringing the arc ends of the semi-cylinder closer to or farther from each other, thereby achieving position adjustment of the optical element.

[0031] It should be noted that the threaded hole of the nut 502 is an M4 threaded hole, the size of the stud 501 matches the nut 502, and the deflection angle of the optical element is adjusted by the stud 501 and the nut 502, with an adjustment accuracy of 0.25° / revolution.

[0032] In some embodiments, the threaded adjustment device 5 also includes a knob 503, which is fixedly disposed at the end of the second end of the stud 501. The knob 503 is provided with anti-slip grooves. The knob 503 provides an operator with a convenient position for gripping and applying force. When it is necessary to adjust the position or state of related components through the threaded adjustment device 5, the user can easily hold the knob 503 and perform a rotation operation.

[0033] In some embodiments, two threaded adjustment devices 5 are provided and are located on the same side of the first mounting plate 2. Two threaded adjustment devices 5 are provided to adjust the optical element from different angles or dimensions. By separately manipulating the two threaded adjustment devices 5, the object to be adjusted can be more accurately positioned to the desired state, meeting high-precision usage requirements, such as accurate calibration of the angle and position of the optical element in a precision optical instrument. In addition, the two threaded adjustment devices 5 can share the force, making the adjustment more stable.

[0034] In some embodiments, the universal mirror frame further includes two wear-resistant pads, both of which are fixedly arranged on the top of the second mounting plate 1, generally by gluing, and are located directly below the two threaded adjustment devices 5, and conflict with the studs 501. The wear-resistant pads have good wear resistance and can withstand long-term and repeated friction, which can effectively reduce the wear of the studs 501 on the surface of the second mounting plate 1, and also reduce the loss of the studs 501 due to friction, thereby extending the service life of the second mounting plate 1 and the studs 501. The wear-resistant pads can make the movement of the studs 501 more stable during the adjustment process, because the wear-resistant pads conflict with the studs 501, and can provide a relatively stable and uniform support surface for the studs 501, thereby preventing the smooth movement of the studs 501 from being affected by factors such as the uneven surface of the mounting plate or the presence of tiny impurities.

[0035] In some embodiments, the two wear pads include a V-shaped wear pad 8 and a circular wear pad 9, the V-shaped wear pad 8 is arranged below one stud 501, and the stud 501 abuts against the V-shaped groove of the V-shaped wear pad 8, and the circular wear pad 9 is arranged below the other stud 501. The setting of the V-shaped groove constrains the movement direction of the stud 501 to a certain extent. When adjusting the angle, the stud 501 in the threaded adjustment device 5 may be subjected to a large force, and there is a risk of deflection when twisting. The setting of the V-shaped groove changes the stud 501 from a point constraint to a line constraint of the V-shaped groove, reduces the degree of freedom of the abutment point of the stud 501, and makes the adjustment process more stable.

[0036] In some embodiments, the gimbal frame also includes a tension spring 7, both ends of which are fixedly connected to the second mounting plate 1 and the first mounting plate 2 respectively, and when the second mounting plate 1 and the first mounting plate 2 are in the initial position, the tension spring 7 is in a natural state, and the tension spring 7 can provide a force opposite to the threaded adjustment device 5. When the threaded adjustment device 5 makes the rectangular parts of the second mounting plate 1 and the first mounting plate 2 approach each other, the tension spring 7 is compressed and can provide elastic force, which can help the first mounting plate 2 to reset. When the threaded adjustment device 5 makes the rectangular parts of the second mounting plate 1 and the first mounting plate 2 move away from each other, the tension spring 7 is stretched and can provide tension to help the first mounting plate 2 to reset.

[0037] In some embodiments, two tension springs 7 are provided, which are respectively located at adjacent positions of two threaded adjustment devices 5, and each tension spring 7 is fixed by two limit pins 6, one of which is clamped at the bottom of the second mounting plate 1, and the other limit pin 6 is clamped at the top of the first mounting plate 2. A cylindrical clamping hole is provided at the bottom of the first mounting plate, and a cylindrical clamping hole is provided at the top of the first mounting plate 2. Both limit pins 6 are made of cylindrical 400C stainless steel. The clamping hole can provide a certain clamping force for the cylindrical pin. When the cylindrical pin is clamped in the clamping hole, whether the tension spring 7 is in a stretched state or a compressed state, the cylindrical pin can remain clamped in a specific position. The installation and disassembly of the cylindrical pin are both carried out with the help of specific tools.

[0038] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
