The patent technology of the telescope prism fixing structure is to set a limit ring. When the prism assembly is fixed, the prism assembly can be pushed toward the limit ring for extrusion. When the prism assembly is extruded onto the limit ring, the triangular slider on the prism assembly will be snapped into the limit groove to form a fixed relationship. The prism assembly is fixed under the snapping action of the triangular slider and the limit groove. However, since the prism assembly is located inside the cylinder, it is impossible to accurately judge whether the installation is in place. Therefore, those skilled in the art provide a telescope prism fixing structure to solve the problems raised in the above background technology. Utility Model Content

[0024] When implementing: Figure 1-6 As shown, a telescope prism fixing structure comprises: a barrel 1, a mounting groove is provided on the surface of the barrel 1, a prism assembly 102 is arranged inside the barrel 1, and a through groove 101 which is distributed in an annular manner and communicated with the barrel 1 is provided on the surface of the mounting groove; a clamping block 104 is slidably connected to the inner wall of the prism assembly 102, one end of the clamping block 104 passes through the prism assembly 102 and the through groove 101 in sequence, a first spring 103 is fixedly connected between the other end of the clamping block 104 and the inner wall of the prism assembly 102, and a plug hole 105 is provided on the surface of the clamping block 104; a trigger mechanism 2, the trigger mechanism 2 is arranged inside the mounting groove, and the trigger mechanism 2 is used to fix the prism assembly 102; an anti-reversal mechanism 3, the anti-reversal mechanism 3 is arranged between one end of the trigger mechanism 2 and the inner wall of the mounting groove, and the anti-reversal mechanism 3 is used to limit the position of the trigger mechanism 2;

[0025] A slope is provided on one side of the block 104, which can squeeze and contract the prism assembly 102 through the inner wall of the barrel 1 and compress the first spring 103 until it moves to the through slot 101. The block 104 can be reset and pass through the through slot 101 under the action of the first spring 103.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the trigger mechanism 2 includes a slip ring 201 slidably connected to the inner wall of the installation groove, the inner edge of the slip ring 201 is provided with a slot 202 connected to the through groove 101, the inner wall of the slot 202 is slidably connected to a trigger plate 203, the surface of the trigger plate 203 is fixedly connected to a connecting rod 204, the other end of the connecting rod 204 is fixedly connected to an indicating block 205 slidably connected to the inner wall of the slip ring 201, one end of the block 104 extends to the inside of the slot 202 and is connected to the trigger plate 203. The surfaces of the release plate 203 are in contact with each other, the inner wall of the card slot 202 is fixedly connected with an insertion rod 206 matching the jack 105, the inner edge of the slip ring 201 is fixedly connected with a top block 207, the top block 207 extends to the inside of the through slot 101 and is slidably connected with the inner wall of the through slot 101, the surface of the slip ring 201 is fixedly connected with a shielding ring, the inner edge of the shielding ring is slidably connected with the surface of the cylinder 1, the shielding ring shields the installation groove, and the surfaces of the shielding ring and the cylinder 1 are both provided with indicator lines;

[0027] When the prism assembly 102 is installed in place, the clamping block 104 can pass through the through slot 101 and be inserted into the adjacent clamping slot 202, and the clamping block 104 can push the trigger plate 203 away from the prism assembly 102, thereby driving the connecting rod 204 to make the indicator block 205 flush with the surface of the slip ring 201, so as to achieve the effect of prompting the user that the installation is in place;

[0028] After the prism assembly 102 is installed in place, the insertion rod 206 can be inserted into the inside of the insertion hole 105 by rotating the slip ring 201, so as to achieve the effect of limiting the position of the block 104, and prevent the prism assembly 102 from shaking during use. At the same time, the top block 207 can prevent the slip ring 201 from sliding along the inner wall of the installation groove due to the restriction of the inner wall of the through groove 101;

[0029] During disassembly, the slip ring 201 is reversed to separate the insertion rod 206 from the insertion hole 105 (the separation of the two can be indicated by the alignment of the indicator lines on the blocking ring and the cylinder 1), and then the slip ring 201 is moved along the inner wall of the installation groove. During this process, the top block 207 can be driven to slide along the inner wall of the through groove 101, so that the wedge surface of the clamping block 104 is squeezed to shrink and separate from the through groove 101 and the clamping slot 202, and the prism assembly 102 can be disassembled. The operation is simple and the installation efficiency is effectively improved.

[0030] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the anti-reversal mechanism 3 includes a connecting ring 301 slidably connected to the inner wall of the installation groove, one side of the connecting ring 301 is rotatably connected to one side of the slip ring 201, a limiting groove 305 is provided on the surface of the connecting ring 301, and the shape of the limiting groove 305 is approximately concave, and a uniformly distributed second spring 302 is fixedly connected between the other side of the connecting ring 301 and the inner wall of the installation groove, and the anti-reversal mechanism 3 also includes a pressure rod 303 arranged on the surface of the shielding ring, the lower end of the pressure rod 303 penetrates the shielding ring and is fixedly connected to the limiting rod 304, and the other end of the limiting rod 304 extends to the inside of the limiting groove 305, and a third spring 306 is fixedly connected between the surface of the pressure rod 303 and the inner wall of the shielding ring;

[0031] The setting of the limit groove 305 can cooperate with the limit rod 304 to limit the position of the pressure rod 303, thereby achieving the effect of limiting the position of the shielding ring, and thus preventing the slip ring 201 from rotating. When the slip ring 201 needs to be rotated, the pressure rod 303 is pushed to drive the third spring 306 to stretch, and the limit rod 304 is moved to the inner bottom wall of the limit groove 305. At this time, the rotating slip ring 201 can slide along the inner wall of the limit groove 305 until it is blocked by its inner wall. Release the pressure rod 303 and the limit rod 304 can be driven by the action of the third spring 306 to reset the pressure rod 303 and insert it into the inner wall of the other end of the limit groove 305. Since the connecting ring 301 does not rotate synchronously with the slip ring 201, its position can be limited by the limit groove 305 in cooperation with the limit rod 304, thereby avoiding the slip ring 201 sliding due to accidental touch during use.

[0032] When the utility model is in use, after the prism assembly 102 is installed in place, the block 104 can pass through the through groove 101 and be inserted into the adjacent slot 202, and the trigger plate 203 can be pushed away from the prism assembly 102 by the block 104, thereby driving the connecting rod 204 to make the indicator block 205 flush with the surface of the slip ring 201, so as to achieve the effect of prompting the user that the installation is in place. At the same time, the slip ring 201 can be rotated to make the insertion rod 206 insert into the inside of the insertion hole 105, so as to achieve the effect of limiting the position of the block 104, and prevent the prism assembly 102 from shaking during use. At the same time, the push block 207 can prevent the slip ring 201 from sliding along the inner wall of the installation groove due to the limitation of the inner wall of the through groove 101, and can limit the position of the slip ring 201 in cooperation with the anti-reversal mechanism 3, and prevent the slip ring 201 from sliding due to accidental touch during use.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
