[0039] refer to Figure 1-4, shows a prism adjustment frame, including a base 1, a clamping platform 2 and an adjustment mechanism 3, the base 1 is provided with a support body 4 with a spherical contour support surface, the base 1 is also provided with a first adjustment hole 12 and a second adjustment hole 13, the line between the axis of the first adjustment hole 12 and the support body 4 is defined as a first axis Z1, the line between the axis of the second adjustment hole 13 and the support body 4 is defined as a second axis Z2, the first axis Z1 and the second axis Z2 are vertically arranged; the clamping platform 2 is provided with a first clamping plate 21 and a second clamping plate 22, and a clamping space 2 is formed between the first clamping plate 21 and the second clamping plate 22 3, a fastener 24 is threadedly connected to the second clamping plate 22, and one end of the fastener 24 extends into the clamping space 23 to press the prism onto the first clamping plate 21; the adjustment mechanism 3 includes a first adjusting bolt 31, a second adjusting bolt 32, and a tension spring 33, the first adjusting bolt 31 is threadedly connected to the first adjusting hole 12, the second adjusting bolt 32 is threadedly connected to the second adjusting hole 13, the tension spring 33 is arranged between the base 1 and the clamping table 2 and provides a pulling force to make the two relatively close, so that the support body 4, the first adjusting bolt 31 and the second adjusting bolt 32 are all in contact with the clamping table 2.

[0040] Specifically, the prism adjustment frame can set the prism between the first clamping plate 21 and the second clamping plate 22, and then use the fastener 24 to fix the prism on the clamping table 2. This structure can realize the installation and disassembly of the prism by screwing the fastener 24; in addition, under the tension of the tension spring 33, when the first adjusting bolt 31 is rotated, the clamping table 2 will rotate around the second axis Z2, and when the second adjusting bolt 32 is rotated, the clamping table 2 will rotate around the first axis Z1, thereby realizing the posture adjustment of the prism on the clamping table 2; the prism adjustment frame can realize the posture adjustment of the prism through a simple structure, which is beneficial to reducing manufacturing costs.

[0041] In the process of the clamping platform 2 rotating around the first axis Z1 or the second axis Z2, the clamping platform 2 abuts against the spherical contour support surface of the support body 4, and the support body 4 provides stable support for the rotation of the clamping platform 2.

[0042] In some embodiments, the support body 4 may be a hemispherical structure integrated with the base 1 , and the hemispherical structure has a supporting surface with a spherical contour.

[0043] In other embodiments, reference Figure 2 and Figure 4, the support body 4 is a sphere, which is a part independent of the base 1; the base 1 is provided with a first clamping hole 11, and the clamping platform 2 is provided with a second clamping hole 25, and the sphere is rotatably clamped in the first clamping hole 11 and the second clamping hole 25 respectively. In this way, the manufacturing of the support body 4 is convenient, the support body 4 can be a steel ball, the first clamping hole 11 and the second clamping hole 25 can be a conical hole, a pyramid hole, a hemispherical hole, etc., the first clamping hole 11 and the second clamping hole 25 can realize the position positioning of the support body 4, and prevent the support body 4 from being displaced relative to the base 1; of course, when the support plate is arranged between the base 1 and the clamping platform 2, there should be a certain gap between the base 1 and the clamping platform 2 to provide enough space to realize the rotation of the clamping platform 2.

[0044] In some embodiments, to prevent the fastener 24 from scratching the surface of the prism, Figure 2 A nylon contact head 241 is provided on one end of the fastener 24 close to the first clamping plate 21. The fastener 24 can be a fastening bolt, and the nylon contact head 241 can be bonded or welded to the end of the fastening bolt; by squeezing the prism through the nylon contact head 241, damage to the prism surface can be avoided during the rotation of the fastener 24, and the prism can also be squeezed and clamped.

[0045] The above solution is preferred. To further prevent the prism from being scratched, refer to Figure 5 At least two convex strips 211 are provided on the inner wall of the first clamping plate 21, and the convex strips 211 and the fasteners 24 are used to clamp the two sides of the prism. In this embodiment, the prism only contacts the convex strips 211, which reduces the contact area between the prism and the first clamping plate 21, and reduces the probability and degree of damage to the prism caused by the first clamping plate 21.

[0046] In some embodiments, to ensure that the tension spring 33 can make the support body 4, the first adjustment bolt 31 and the second adjustment bolt 32 abut against the clamping platform 2, refer to Figure 2 and Figure 3 There are two tension springs 33 , one of which is arranged between the support body 4 and the first adjustment hole 12 , and the other tension spring 33 is arranged between the support body 4 and the second adjustment hole 13 .

[0047] Specifically, in order to facilitate the installation of the tension spring 33, refer to Figure 2-4The base 1 is provided with two first connecting holes 14, which are respectively arranged between the support body 4 and the first adjusting hole 12 and between the support body 4 and the second adjusting hole 13; a first card slot 141 is recessed on the wall surface of the base 1 away from the clamping platform 2, and the first card slot 141 corresponds to the position of the first connecting hole 14; two second connecting holes 26 are provided on the clamping platform 2, and the two second connecting holes 26 correspond to the position of the first connecting hole 14; a second card slot 261 is recessed on the wall surface of the clamping platform 2 away from the base 1, and the second card slot 261 corresponds to the position of the second connecting hole 26; a card pin 331 is provided in each of the first card slot 141 and the second card slot 261, one end of the tension spring 33 passes through the first connecting hole 14 and is hooked to the card pin 331 located in the first card slot 141, and the other end of the tension spring 33 passes through the second connecting hole 26 and is hooked to the card pin 331 located in the second card slot 261.

[0048] Thus, in this embodiment, the tension spring 33 and the base 1 and the clamping platform 2 are not connected by welding or other means, which reduces the difficulty of installation. At the same time, the tension spring 33 can be removed to facilitate replacement of the tension spring 33 .

[0049] It should be noted that the reference Figure 4 The pin 331 in the second slot 261 should be completely embedded in the second slot 261 to avoid affecting the installation of the prism in the clamping space 23.

[0050] In some embodiments, reference Figure 3 The base 1 is provided with a first mounting hole 15 and a second mounting hole 16; the prism adjustment frame further comprises a supporting module 5, the base 1 is arranged above the supporting module 5, and the supporting module 5 is connected to the first mounting hole 15 or the second mounting hole 16;

[0051] refer to Figure 6 , when the support module 5 is connected to the first mounting hole 15, the clamping platform 2 is located above the base 1; when the clamping platform 2 rotates around the first axis Z1 or the second axis Z2, the pitch angle of the prism can be adjusted;

[0052] refer to Figure 7 , when the support module 5 is connected to the second mounting hole 16, the clamping platform 2 is located on the side of the base 1; when the clamping platform 2 rotates around the first axis Z1, the horizontal deflection angle of the prism can be adjusted;

[0053] In this way, the prism adjustment stand has a variety of application modes and can meet more usage requirements.

[0054] In the above solution, the types of prisms include but are not limited to triangular prisms, quadrangular prisms, etc.; the support module 5 can adopt conventional optical support rods.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
