Description

Technical Field

[0001] The invention relates to a sighting scope, in particular to a sighting scope with mechanical switching of two-color single points. Background Art

[0002] The red dot sight allows the shooter to easily find and shoot the target, which is great for hunting. It helps the shooter to be better aware of the surroundings because the shooter can open both eyes and see the target faster.

[0003] The structural principle of the red dot sight is to set a point light source under the inner tube. When the red dot emitted by the point light source is directed to the dichroic mirror, its light will be reflected by the reflective coating on the dichroic mirror. The reflected light is emitted parallel to the main axis of the sight, so that the shooter's eyes can see the red dot at infinity. This is the red dot sight.

[0004] The most common point light source in red dot sights is a red LED, and now there are other color options. With the advancement of technology, two-color light points can be encapsulated in the same LED, but the same light point cannot emit two colors at the same time, and this two-color LED is usually in the form of a pattern, such as a red dot in the middle and a circle around the red dot. In addition, LEDs with dual (multi) color patterns are more expensive, which will increase the cost of red dot sights, and consumers often need to bear the higher price. Summary of the invention

[0005] The present invention provides a mechanically switched dual-color single-point sight, comprising a sight body, an inner mirror tube, a lamp component and a first elastic component, wherein the inner mirror tube is arranged in the sight body, the lamp component is arranged on the tube wall of the inner mirror tube, the first elastic component is arranged between the inner wall of the sight body and the outer wall of the inner mirror tube, the lamp component is provided with a first LED lamp and a second LED lamp arranged in parallel, and further comprising:

[0006] An adjustment base, which is arranged on the mirror body, has two slots on the peripheral wall of the adjustment base, and a slide groove is arranged at the bottom of the adjustment base, one end of the slide groove is located at the end of one slot, and the other end of the slide groove is located at the end of the other slot;

[0007] An adjusting cover is arranged on the adjusting base and is rotatably connected with the adjusting base. A boss is arranged on the inner wall of the adjusting cover. The boss can be accommodated in the card slot and can move from one card slot to another card slot through the slide slot.

[0008] a second elastic component, one end of the second elastic component is pressed against the adjustment base, and the other end of the second elastic component is pressed against the inner top of the adjustment cover; and

[0009] An adjustment seat is provided with an adjustment screw on the first end of the adjustment seat, and the end of the adjustment screw passes through the adjustment base and the rear end of the endoscope body in sequence and presses against the outer wall of the endoscope tube. The adjustment cover can drive the adjustment seat to rotate synchronously so that the adjustment screw moves along its axial direction.

[0010] The mechanically switchable two-color single-point sight of the present invention comprises a first LED lamp and a second LED lamp of two different colors. For example, the first LED lamp emits a red dot and the second LED lamp emits a green dot. When installing the lamp component, the position of the first LED lamp or the second LED lamp is determined in coordination with the impact point. Assuming that the sight is currently using a red dot for aiming and needs to be switched to a green dot for aiming, firstly, the first LED lamp (red light) is turned off by the switch of the lamp component, and the second LED lamp (green light) is turned on, so that the luminous color of the lamp component is switched from red to green. Then, the adjusting cover is pressed, and the boss on the adjusting cover is disengaged from a slot on the adjusting base and enters the slide slot. Then, the adjusting cover is rotated, and the boss on the adjusting cover moves through the slide slot to the end of the other slot. At this time, the adjusting cover is released, and under the elastic force of the second elastic component, the boss on the adjusting cover is clamped in the other slot. Since the adjusting cover can drive the adjusting base to rotate synchronously so that the adjusting screw moves along its axial direction, in this way, the boss on the adjusting cover moves from the adjusting base to the adjusting base. A slot on the joint base moves to another slot, and the adjusting screw on the adjustment seat will push the endoscope tube to move, or the endoscope tube pushes the adjusting screw on the adjustment seat to move under the elastic force of the first elastic component, and the endoscope tube drives the lamp component to move synchronously. By setting the boss to move from one slot to another, the moving distance of the adjusting screw (or endoscope tube) is equivalent to the spacing between the first LED lamp and the second LED lamp. In this way, the second LED lamp will move to the original position of the first LED lamp, and the second LED lamp will replace the position of the first LED lamp. At this time, the mechanical color switching of the sight is completed. The same method can also realize the position where the first LED lamp replaces the second LED lamp. The color switching of the luminous point in the sight can be achieved by operating the adjustment cover. The operation is very simple. The sight of the present invention provides a two-color single-point sight structure. The shooter can switch the color of the luminous point according to different shooting environments to ensure that the shooter can accurately see the target.

[0011] Preferably, the first LED lamp is a red LED, the second LED lamp is a green LED, and the distance between the first LED lamp and the second LED lamp is L1.

[0012] When the boss moves from one slot through the slide groove to another slot, the distance the adjusting screw moves along its axial direction is L2, and L2=L1.

[0013] Therefore, in this case, when the boss moves from one slot to another, the distance the adjusting screw moves along its axial direction is L2, that is, the distance the endoscope tube drives the lamp component to move is also L2, and when the boss moves in the opposite direction, the distance the adjusting screw moves along its axial direction is -L2, that is, the distance the endoscope tube drives the lamp component to move is also -L2. Since the distance between the first LED lamp and the second LED lamp is L1 and L1=L2, when the boss moves from one slot to another, the second LED lamp will replace the original position of the first LED lamp or the first LED lamp will replace the original position of the second LED lamp, thereby realizing the switching of the color of the light-emitting point in the sight.

[0014] Preferably, an annular protrusion is provided on the inner top of the adjustment cover, an inner wall of the annular protrusion is provided with an inner tooth portion, and an outer tooth portion is provided on the second end of the adjustment seat, and the outer tooth portion is meshed with the inner tooth portion.

[0015] Therefore, after pressing the adjustment cover, the boss on the adjustment cover disengages from a slot on the adjustment base and enters the slide slot, and then the adjustment cover is rotated, the annular protrusion on the top inner side of the adjustment cover rotates synchronously, and the inner teeth on the inner wall of the annular protrusion rotates synchronously. Since the inner teeth are engaged with the outer teeth on the adjustment seat, the adjustment cover will drive the adjustment seat to rotate synchronously, thereby causing the adjustment screw on the adjustment seat to move along the axial direction of the adjustment screw, the adjustment screw drives the endoscope tube to move synchronously, and the endoscope tube drives the lamp component to move synchronously to realize the second LED lamp replacing the original position of the first LED lamp or the first LED lamp replacing the original position of the second LED lamp, thereby realizing the switching of the color of the light-emitting point in the sight.

[0016] Preferably, it also includes a limiting ring, which is sleeved on the adjusting base, and the adjusting cover is threadedly connected to the limiting ring so that the adjusting cover can rotate on the adjusting base.

[0017] Therefore, the limiting ring can ensure that the adjusting cover will not be separated from the adjusting base during the rotation process.

[0018] Preferably, the adjusting base is provided with a first internal thread, the adjusting seat is provided with a first external thread matched with the first internal thread, and the adjusting seat is screwed into the adjusting base.

[0019] Therefore, the adjustment base and the scope body can be connected by threads, and when the boss moves from one slot to another, the adjustment cover drives the adjustment seat to rotate synchronously. Since the adjustment seat and the adjustment base are connected by threads, when the adjustment seat rotates, the adjustment seat will move along its axial direction, and the adjustment seat drives the adjusting screw to move synchronously along the axial direction of the adjusting screw. As long as the parameters of the first internal thread and the first external thread are set to ensure that when the boss moves from one slot to another, the distance that the adjusting screw moves along its axial direction is equivalent to the moving distance of the endoscope tube and the distance between the first LED light and the second LED light, the color switching of the light-emitting point in the sight can be achieved.

[0020] Preferably, it also includes left and right adjustment knobs, the adjustment seat includes an annular knob cover and a base, the base is hollow, the first end of the base is provided with a through hole connected to the inner cavity of the base, the left and right adjustment knobs are accommodated in the base, one end of the left and right adjustment knobs is provided with a second internal thread adapted to the adjustment screw, the adjustment screw passes through the through hole and is rotated in the left and right adjustment knobs, the annular knob cover is rotated on the base, the other end of the left and right adjustment knobs is provided with an adjustment groove, the adjustment cover is provided with an accommodating hole, the other end of the left and right adjustment knobs is inserted in the accommodating hole, the first external thread is provided on the outer wall of one end of the base, and the external tooth portion is provided on the outer wall of the annular knob cover.

[0021] Therefore, when the boss moves from one slot to another, the adjustment cover will drive the annular knob cover to rotate synchronously, and the annular knob cover can drive the base, the adjustment screw, and the left and right adjustment knobs in the base to rotate as a whole. Since the base of the adjustment seat is connected to the adjustment base through a threaded connection, when the adjustment cover rotates, the base, the adjustment screw, and the left and right adjustment knobs in the base move axially as a whole, and the adjustment screw drives the endoscope tube to move synchronously, and the endoscope tube drives the light component to move synchronously to realize the second LED light replacing the original position of the first LED light or the first LED light replacing the original position of the second LED light, so as to realize the switching of the light-emitting point color in the sight. At the same time, when the left and right direction position of the endoscope tube needs to be adjusted (non-light-emitting point color switching The purpose of this invention is to use a tool to turn the adjustment slots on the left and right adjustment knobs, and the left and right adjustment knobs rotate in the base. Under the joint action of the first elastic component, the left and right adjustment knobs will drive the adjustment screws to move along their axial directions, thereby realizing the adjustment of the left and right positions of the endoscope tube. In this way, the existing left and right adjustment components on the sight (left and right adjustment knobs, adjustment screws) and the components for mechanically switching the color of the luminous points (adjustment cover, adjustment seat, adjustment screws) can be integrated together and installed together on the adjustment base. Of course, the positions of the first LED light and the second LED light can also be adjusted by directly turning the left and right adjustment knobs, but they cannot be adjusted accurately. When the color of the luminous point needs to be switched, the adjustment cover will be turned to realize the accurate switching of the positions of the first LED light and the second LED light.

[0022] Preferably, a second external thread is provided on the outer wall of the second end of the base, and the annular knob cover is screwed onto the second external thread.

[0023] Therefore, in this case, when the adjustment cover drives the annular knob cover to rotate, the annular knob cover can smoothly drive the base, the adjustment screw, and the left and right adjustment knobs in the base to rotate as a whole. Moreover, the annular knob cover is detachably connected to the base through the second external thread, which facilitates the installation and disassembly of the left and right adjustment knobs.

[0024] Preferably, the through hole is in an oblong shape, and the adjusting screw includes a threaded section and a receiving section that are integrally connected, the threaded section is screwed into the left and right adjustment knobs, and two parallel planar portions are provided on the outer periphery of the receiving section, the receiving section is received in the through hole, and the end of the receiving section is pressed against the outer wall of the endoscope tube.

[0025] Therefore, since the through hole is in an oblong shape and the accommodation section of the adjusting screw is accommodated in the through hole, when it is necessary to switch the color of the luminous point, the adjusting cover is rotated, and the base can drive the adjusting screw to rotate synchronously so that the adjusting screw moves along its axial direction. When the left and right adjusting knobs are turned, the left and right adjusting knobs can also drive the adjusting screw to move along its axial direction (that is, the accommodation section of the adjusting screw moves along the axial direction of the accommodation section in the through hole), so that the existing left and right adjustment components on the sight (left and right adjustment knobs, adjustment screws) and the components for mechanically switching the color of the luminous point (adjustment cover, adjustment seat, adjustment screws) can be integrated together and installed together on the adjustment base.

[0026] Preferably, it also includes a fixing cap, a spring and a pin, a circle of teeth is provided on the inner wall of the base, and the left and right adjustment knobs are provided with through holes arranged perpendicular to their axes, the fixing cap, spring and pin are all accommodated in the through holes, one end of the spring abuts on the fixing cap, the other end of the spring abuts on one end of the pin, and the other end of the pin extends from the outer wall of the left and right adjustment knobs and abuts on the teeth.

[0027] Therefore, when the left and right adjustment knobs are turned, the balls extending from the outer walls of the left and right adjustment knobs will rotate synchronously, and the balls will flick the teeth on the inner wall of the base, making a flicking sound, so that the shooter can know the rotation angle of the left and right adjustment knobs according to the flicking sound, and thus can quantitatively adjust the left and right position of the endoscope tube to accurately aim at the target.

[0028] Preferably, the first elastic component is a spring, and the second elastic component is a spring.

[0029] Therefore, the spring sheet and the adjusting screw can jointly realize the left-right movement of the endoscope tube. When the boss on the adjusting cover moves to the end of another slot through the sliding groove, after the adjusting cover is released, the boss on the adjusting cover can be snapped into another slot under the restoring force of the spring.

The length direction of the groove 51 is parallel to the axial direction of the first external threaded portion 54. A slide groove 52 is formed at the bottom of the adjusting base 5. The slide groove 52 is located below the part between the two grooves 51 of the surrounding edge 56, one end of the slide groove 52 is located at the end of one groove 51, and the other end of the slide groove 52 is located at the end of the other groove 51.

[0050] The adjustment cover 6 is mounted on the adjustment base 5 and is rotatably connected to the adjustment base 5. Figures 2 to 4 , Figure 6 and Figure 7 A circle of steps 55 are formed on the adjusting base 5, and the limiting ring 9 is sleeved on the adjusting base 5. A circle of overlapping edges 901 on the limiting ring 9 is clamped on a circle of steps 55 on the adjusting base 5. A first internal thread portion 93 is formed on the limiting ring 9, and a second external thread portion 66 adapted to the first internal thread portion 93 is formed on the outer wall of the adjusting cover 6. The adjusting cover 6 is covered on the outer periphery of the surrounding edge 56 and is threadedly connected with the limiting ring 9. In this way, the adjusting cover 6 can rotate on the adjusting base 5, and the limiting ring 9 can ensure that the adjusting cover 6 will not be separated from the adjusting base 5 during the rotation process.

[0051] See also Figure 4 , Figure 6 and Figure 7One end of the second elastic member 7 is pressed against the adjustment base 5, and the other end of the second elastic member 7 is pressed against the inner top of the adjustment cover 6. Figure 6 A boss 61 is formed on the inner wall of the adjusting cover 6, and the boss 61 can be accommodated in the slot 51 on the adjusting base 5. After pressing the adjusting cover 6, the overlap 901 on the limiting ring 9 is separated from the step 55 on the adjusting base 5, and the boss 61 on the adjusting cover 6 can escape from one slot 51 on the adjusting base 5 and enter the slide groove 52. Then, when the adjusting cover 6 is rotated, the boss 61 on the adjusting cover 6 can move to the end of the other slot 51 through the slide groove 52. Then, after the adjusting cover 6 is released, under the elastic force of the second elastic component 7, the boss 61 on the adjusting cover 6 is snapped into the other slot 51.

[0052] In this embodiment, the second elastic component 7 is a spring, and the spring in a compressed state is installed between the adjustment cover 6 and the adjustment base 5. In other embodiments, the second elastic component 7 can also use other elastic structures, as long as it can ensure that under the elastic force of the second elastic component 7, the boss 61 on the adjustment cover 6 can be clamped in the clamping groove 51 from the end of the slide groove 52.

[0053] See also Figure 6 and Figure 7 The adjusting base 5 is formed with a first internal thread 53, and the outer wall of the first end of the adjusting base 8 is provided with a first external thread 83 adapted to the first internal thread 53. The adjusting base 8 is screwed into the adjusting base 5. Figure 3 and Figure 4 The first end of the adjustment seat 8 is provided with an adjustment screw 81, and the bottom end of the adjustment screw 81 passes through the adjustment base 5 and the mirror body 1 in sequence and then presses against the outer wall of the endoscope tube 2 ( Figure 2 shown).

[0054] See also Figure 6An annular protrusion 62 is formed on the inner top of the adjusting cover 6, and the end of the spring (the second elastic component 7) is enclosed in the outer periphery of the annular protrusion 62 and pressed against the inner top of the adjusting cover 6. An inner tooth portion 63 is formed on the inner wall of the annular protrusion 62, and an outer tooth portion 82 is provided on the second end of the adjusting seat 8. The outer tooth portion 82 meshes with the inner tooth portion 63. In this way, when the adjusting cover 6 rotates, the adjusting cover 6 will drive the adjusting seat 8 to rotate synchronously through the structure of the outer tooth portion 82 and the inner tooth portion 63. 8 is connected to the adjustment base 5 by a thread. In this way, when the adjustment base 8 rotates, the adjustment base 8 will move along the axial direction of the adjustment base 8, and the adjustment base 8 drives the adjusting screw 81 to move synchronously along the axial direction of the adjusting screw 81; after pressing the adjustment cover 6, when the adjustment cover 6 rotates, the boss 61 on the adjustment cover 6 moves from one slot 51 to another slot 51, and the distance that the adjusting screw 81 moves along its axial direction is L2, that is, the distance that the endoscope tube 2 drives the lamp component 3 to move is also L2, and the boss 61 When the reverse movement occurs, that is, the adjustment cover 6 rotates in the opposite direction, the distance that the adjustment screw 81 moves along its axial direction is -L2, that is, the distance that the endoscope tube 2 drives the lamp component 3 to move is also -L2. Since the spacing between the first LED lamp 31 and the second LED lamp 32 is L1, as long as the parameters of the first internal thread 53 on the adjustment base 5 and the first external thread 83 on the adjustment seat 8 are set so that L1=L2, that is, when the boss 61 on the adjustment cover 6 moves from one slot 51 to another slot 51, the distance L2 that the adjustment screw 81 moves along the axial direction of the adjustment screw 81 is equivalent to the moving distance of the endoscope tube 2 and the spacing L1 between the first LED lamp 31 and the second LED lamp 32. In this way, when the boss 61 on the adjustment cover 6 moves from one slot 51 to another slot 51, the second LED lamp 32 will replace the original position of the first LED lamp 31 or the first LED lamp 31 will replace the original position of the second LED lamp 32, thereby realizing the mechanical switching of the color of the light-emitting point in the sight.

[0055] See also Figure 6 , an R mark 91 and a G mark 92 are formed on the outer wall of the limit ring 9. When the boss 61 on the adjustment cover 6 is snapped into the slot 51 on the right, the red dot emitted by the first LED lamp 31 is emitted to the diffraction mirror in the sight, and its light is reflected by the reflective coating on the diffraction mirror. The reflected light is emitted parallel to the main axis of the sight, so that the shooter's eyes can see the red dot at infinity. When the boss 61 on the adjustment cover 6 is snapped into the slot 51 on the left, the green dot emitted by the second LED lamp 32 is emitted to the diffraction mirror in the sight, and its light is reflected by the reflective coating on the diffraction mirror. The reflected light is emitted parallel to the main axis of the sight, so that the shooter's eyes can see the green dot at infinity; refer to Figure 1A mark 110 may be formed on the lens body 1. When the R mark 91 on the adjustment cover 6 is aligned with the mark 110, the shooter's eyes can see a red dot at infinity. When the G mark 92 on the adjustment cover 6 is aligned with the mark 110, the shooter's eyes can see a green dot at infinity.

[0056] See also Figures 7 to 11In this embodiment, the adjustment seat 8 includes an annular knob cover 801 and a base 802. The base 802 is hollow. A through hole 8021 communicating with the inner cavity of the base 802 is formed at the first end of the base 802. A first external thread 83 is arranged on the outer wall of the first end of the base 802. The left and right adjustment knobs 10 are accommodated in the base 802. A sealing ring can be installed between the outer wall of the left and right adjustment knobs 10 and the inner wall of the base 802 for dustproof and waterproofing. A second internal thread 101 adapted to the adjustment screw 81 is formed at one end of the left and right adjustment knobs 10. The adjustment screw 81 passes through the through hole 8021 and is rotated in the second internal thread 101 of the left and right adjustment knobs 10. A second external thread 8022 is formed on the outer wall of the second end of the base 802, and the annular knob cover 801 is screwed on the second external thread 8022 on the base 802. The other end of the left-right adjustment knob 10 is formed with a straight-line adjustment groove 102, and the adjustment cover 6 is formed with a receiving hole 64. The other end of the left-right adjustment knob 10 passes through the annular knob cover 801 and is inserted into the receiving hole 64 on the adjustment cover 6. The external tooth portion 82 is arranged on the outer wall of the annular knob cover 801, and the external tooth portion 82 is meshed with the internal tooth portion 63 on the adjustment cover 6. The end of the spring (the second elastic component 7) is enclosed in the outer periphery of the annular knob cover 801 and is pressed against the adjustment base 5.The adjusting cover 6 is pressed and rotated. When the boss 61 on the adjusting cover 6 moves from one slot 51 to another slot 51, the adjusting cover 6 will drive the annular knob cover 801 to rotate synchronously. The annular knob cover 801 can drive the base 802, the adjusting screw 81, and the left and right adjusting screws 10 in the base 802 to rotate as a whole. Since the base 802 of the adjusting seat 8 is connected to the adjusting base 5 by threads, when the adjusting cover 6 rotates, the base 802, the adjusting screw 81, and the left and right adjusting screws 10 in the base 802 move along the axial direction of the left and right adjusting screws 10 as a whole. The adjusting screw 81 drives the endoscope tube 2 to move synchronously. The endoscope tube 2 drives the lamp component 3 to move synchronously to realize that the second LED lamp 32 replaces the original position of the first LED lamp 31 or the first LED lamp 31 replaces the original position of the second LED lamp 32, so as to realize the switching of the color of the light-emitting point in the sight. At the same time, the endoscope tube 8 needs to be adjusted. 2 (not for the purpose of switching the color of the luminous point), use a tool to twist the adjustment slot 101 on the left and right adjustment knob 10, and the left and right adjustment knob 10 rotates in the base 802. Under the joint action of the first elastic component 4, the left and right adjustment knob 10 drives the adjustment screw 81 to move along the axial direction of the adjustment screw 81, thereby achieving the adjustment of the left and right position of the endoscope tube 2. In this way, the existing left and right adjustment components (left and right adjustment knob 10, adjustment screw 81) on the sighting scope and the components for mechanically switching the color of the luminous point (adjustment cover 6, adjustment seat 8, adjustment screw 81) can be integrated together and installed together on the adjustment base 5. Of course, directly twisting the left and right adjustment knob 10 can also adjust the position of the first LED lamp 31 and the second LED lamp 32, but it cannot be adjusted accurately. When it is necessary to switch the color of the luminous point, the adjustment cover 6 will be twisted to achieve the accurate switching of the position of the first LED lamp 31 and the second LED lamp 32. ;

[0057] See also Figure 8 and Fig. 9The adjusting screw 81 includes a threaded section 811 and a receiving section 812 which are integrally connected. The through hole 8021 is in an oblong shape. The threaded section 811 is rotated in the left and right adjusting knobs 10. Two parallel planar portions 813 are formed on the outer periphery of the receiving section 812. The two planar portions 813 are respectively located on opposite sides of the receiving section 812. The receiving section 812 is received in the through hole 8021. The end of the receiving section 812 passes through the adjusting base 5 and the mirror body 1 in sequence and then presses against the outer wall of the endoscope tube 2. Since the through hole 8021 is in an oblong shape and the receiving section 812 of the adjusting screw 81 is received in the through hole 8021, when the color of the luminous point needs to be switched, the adjusting cover 6 is rotated and the base 802 The adjusting screw 81 can be driven to rotate synchronously so that the adjusting screw 81 moves along the axial direction of the adjusting screw 81. When the left and right adjusting knobs 10 are turned, the left and right adjusting knobs 10 can also drive the adjusting screw 81 to move along the axial direction of the adjusting screw 81 (that is, the accommodating section 812 of the adjusting screw 81 moves along the axial direction of the accommodating section 812 in the through hole 8021), thereby realizing that the existing left and right adjustment components on the sight (left and right adjustment knobs 10, adjusting screw 81) and the components for mechanically switching the color of the luminous point (adjustment cover 6, adjustment seat 8, adjustment screw 81) can be integrated together and installed together on the adjustment base 5, and the components for mechanically switching the color of the luminous point will not occupy additional area on the scope body 1.

[0058] See also Figure 8 and Fig. 9 A circle of tooth grooves 8023 is formed on the inner wall of the base 802, and a through hole 103 arranged perpendicularly to the axis of the left and right adjustment knob 10 is formed. The fixing cap 11, the spring 12 and the ball 13 are all accommodated in the through hole 103, one end of the spring 12 abuts on the fixing cap 11, the other end of the spring 12 abuts on one end of the ball 13, and the other end of the ball 13 extends from the outer wall of the left and right adjustment knob 10 and abuts on the tooth groove 8023. In addition, refer to Figure 1 A circle of scale lines 65 is formed on the adjustment cover 6, and a circle of scale lines 65 is arranged around the outer periphery of the adjustment groove 102. In this way, when the left and right adjustment knobs 10 are turned, the balls 13 extending from the outer walls of the left and right adjustment knobs 10 will rotate synchronously, and the balls 13 will move the tooth grooves 8023 on the inner wall of the base 802, making a moving sound. The shooter can know the rotation angle of the left and right adjustment knobs 10 by comparing the scale lines 65 and the number of moving sounds, so as to quantitatively adjust the left and right positions of the endoscope tube 2 to accurately aim at the target.

[0059] See also Figures 1 to 11In the mechanically switchable dual-color single-point sight of the present invention, the light component 3 is a first LED light 31 and a second LED light 32 of two different colors. The first LED light 31 emits a red dot, and the second LED light 32 emits a green dot. When installing the light component 3, the position of the first LED light 31 or the second LED light 32 is determined in coordination with the impact point, so that when the red dot or green dot emitted by the first LED light 31 or the second LED light 32 is emitted to the light analyzer in the sight, its light is reflected by the reflective coating on the light analyzer, and the reflected light is emitted parallel to the main axis of the sight, so that the shooter's eyes can see the red dot or green dot at infinity. Green dot; assuming that the sight is using the red dot aiming, that is, the R mark 91 on the adjustment cover 6 is aligned with the mark 110, it is necessary to switch to the green dot aiming, first turn off the first LED light 31 through the switch of the lamp component 3, turn on the second LED light 32, and switch the luminous color of the lamp component 3 from red to green, and then press the adjustment cover 6 (at this time, a circle of overlap 901 on the limit ring 9 is separated from a circle of steps 55 on the adjustment base 5), the boss 61 on the adjustment cover 6 is disengaged from a slot 51 on the adjustment base 5 and enters the slide slot 52, and then the adjustment cover 6 is rotated, and the adjustment cover 6 drives the annular knob cover 801 to rotate synchronously The annular knob cover 801 drives the base 802, the adjusting screw 81, and the left and right adjusting screws 10 to rotate as a whole. Since the base 802 is connected to the adjusting base 5 by a thread, when the adjusting cover 6 rotates, the base 802, the adjusting screw 81, and the left and right adjusting screws 10 move along the axial direction of the left and right adjusting screws 10 as a whole, and the adjusting screw 81 drives the endoscope tube 2 to move synchronously, and the endoscope tube 2 drives the lamp component 3 to move synchronously. The boss 61 on the adjusting cover 6 moves to the end of the other card slot 51 through the slide slot 52, and then the adjusting cover 6 is released. Under the elastic force of the second elastic component 7, the adjusting The boss 61 on the cover 6 is clamped in another clamping groove 51. At this time, the G mark 92 on the cover 6 is adjusted to align with the mark 110. In this process, the distance that the adjusting screw 81 moves along its axial direction is L2, that is, the distance that the endoscope tube 2 drives the lamp component 3 to move is also L2. Since the intervals L1 and L2 between the first LED lamp 31 and the second LED lamp 32 are equal, when the G mark 92 on the cover 6 is adjusted to align with the mark 110, the second LED lamp 32 replaces the original position of the first LED lamp 31, realizing the switching of the light point color in the sight from red to green, and the mechanical switching of the color of the sight is completed.If it is necessary to switch back to the red dot aiming, first turn off the second LED light 32 through the switch of the lamp component 3, turn on the first LED light 31, switch the luminous color of the lamp component 3 from green to red, then press the adjustment cover 6, rotate the adjustment cover 6 in the opposite direction, and under the elastic force of the first elastic component 4, the adjustment screw 81 moves along its axial direction. When the R mark 91 on the adjustment cover 6 is aligned with the mark 110, the boss 61 on the adjustment cover 6 moves from one slot 51 to another slot 51. In this process, the adjustment screw 81 moves along its axial direction by a distance of -L2, and the endoscope tube 2 drives the lamp component 3 to move by a distance of -L2. Due to the first The spacing L1 and L2 between the LED light 31 and the second LED light 32 are equal, so when the R mark 91 on the adjustment cover 6 is aligned with the mark 110, the first LED light 31 replaces the original position of the second LED light 32, realizing the switching of the color of the light point in the sight from green to red, and the mechanical color switching of the sight is completed at this time; the color switching of the light point in the sight can be achieved by operating the adjustment cover 6, and the operation is very simple. The sight of the present invention provides a two-color single-point sight structure, and the shooter can switch the color of the light point according to different shooting environments to ensure that the shooter can accurately see the target. In addition, when the left-right position of the endoscope tube 2 needs to be adjusted (not for the purpose of switching the color of the light point), the adjustment groove 101 on the left-right adjustment knob 10 is turned with a tool, and the left-right adjustment knob 10 rotates in the base 802. Under the joint action of the first elastic component 4, the left-right adjustment knob 10 drives the adjustment screw 81 to move along the axial direction of the adjustment screw 81, thereby achieving the adjustment of the left-right position of the endoscope tube 2. In this way, the existing left-right adjustment components (left-right adjustment knob 10, adjustment screw 81) on the sight and the components for mechanically switching the color of the light point (adjustment cover 6, adjustment seat 8, adjustment screw 81) can be integrated together and installed together on the adjustment base 5. Of course, directly turning the left-right adjustment knob 10 can also adjust the position of the first LED lamp 31 and the second LED lamp 32, but it cannot be adjusted accurately. When the color of the light point needs to be switched, the adjustment cover 6 is turned to achieve the accurate switching of the position of the first LED lamp 31 and the second LED lamp 32. ;
