Description

Technical Field

[0001] This utility model belongs to the field of aiming scope technology, and in particular relates to a high-precision aiming scope reticle adjustment device with locking function. Background Technology

[0002] The reticle adjustment device is an important component of a scope. In shooting, observation, and other activities, precise adjustment of the scope reticle and rapid locking after adjustment are crucial for improving shooting accuracy and adapting to different observation objects and targets. However, existing scope reticle adjustment devices have the following shortcomings.

[0003] While some reticle adjustment devices can adjust the reticle, they lack an effective locking mechanism. Under the influence of recoil from firearms firing and vibrations from device movement, the reticle is prone to displacement, leading to a decrease in aiming accuracy and failing to meet the requirements of high-precision shooting and observation. Other reticle adjustment devices, although they have locking functions, are complex to operate, requiring additional tools or cumbersome steps to lock and unlock the reticle, reducing the efficiency of the reticle adjustment device and making it difficult to operate quickly and accurately in emergency or dynamic scenarios.

[0004] Therefore, a new technical solution is urgently needed among existing technologies to solve this problem. Utility Model Content

Equipped with internal and external connecting threads, the fixed cylinder is fixedly connected to the external device via the external connecting thread, and rotatably connected to the reticle adjustment shaft via the internal connecting thread. The reticle adjustment shaft is a columnar structure with a square top, the shortest side of which is greater than the maximum radial dimension. The reticle adjustment shaft is inserted into a square hole at the bottom of the rotating cylinder, and engages circumferentially with the square hole at the bottom of the rotating cylinder via its square top structure. The outer surface of the columnar portion of the reticle adjustment shaft has connecting threads, and it is rotatably connected to the fixed cylinder via the internal thread at the bottom of the fixed cylinder. (Indicator drum, rotating cylinder, ...) The fixed cylinder, the reticle adjustment shaft, and the other three components are arranged with their rotation axes coincidentally and sleeved together. The characteristic feature is that it also includes a locking device for the reticle adjustment shaft, which comprises a locking handwheel and a locking pin. The locking handwheel has a disc-shaped structure with threaded holes on its circumference and bottom. The locking pin is a cylindrical structure with a tapered bottom, the tapered shape pointing inwards towards the interior of the rotating cylinder. External threads on the outer surface of the locking pin mate with the internal threads of the rotating cylinder and the threaded holes at the bottom of the locking handwheel. The locking pin is screwed into the threaded hole at the bottom of the locking handwheel, and the locking pin and the locking handwheel are connected by a hand... The handwheel is fixedly connected by a set screw; the set screw is screwed into the circumferential threaded hole of the locking handwheel; the locking device of the graduated adjustment shaft also includes a click pin and a spring; one end of the spring is fixedly installed on the inner wall opposite to the hole of the rotating cylinder, and the other end of the spring is sleeved on the click pin; the click pin is a columnar structure with a tapered end, the tapered part of which extends out of the rotating cylinder through the hole and engages with the toothed groove on the inner surface of the fixed cylinder, and the columnar structure of the click pin is provided with an annular groove that engages with the tapered bottom of the locking pin; the number of toothed grooves corresponds to the number of scale lines on the indicator drum.

[0007] The high-precision aiming scope reticle adjustment device with locking function of this utility model also includes a pressure cover, which covers the top of the fixed cylinder and is threadedly fixed to the fixed cylinder.

[0008] The present invention provides a high-precision sight reticle adjustment device with locking function, which also includes a sealing ring. The sealing ring is circular and is fixedly engaged in the gap between the fixed cylinder and the rotating cylinder.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. It should be noted that although this utility model belongs to the field of aiming scope technology, it is also applicable to other fields that require precise adjustment, such as the field of optical instruments.

[0024] like Figure 1 The high-precision sight reticle adjustment device with locking function shown includes an indicator drum 1 and a rotating cylinder 4. The indicator drum 1 is a hollow cylindrical structure with graduations on its outer surface, the number of which corresponds to the number of grooves 601 inside the fixed cylinder 6. The rotating cylinder 4 is a cylindrical structure with an outer diameter smaller than the inner diameter of the indicator drum 1, such as... Figure 3 and Figure 4As shown, the bottom of the rotating cylinder 4 has a square hole 403 that matches the square structure 701 on the top of the reticle adjustment shaft 7. The rotating cylinder 4 is built into the cavity of the indicator drum 1 and the two are fixedly connected by the indicator drum set screw 10. When the user rotates the indicator drum 1, the indicator drum 1 drives the rotating cylinder 4 to rotate through the set screw 10. Because the square hole 403 at the bottom of the rotating cylinder 4 and the square structure 701 on the top of the reticle adjustment shaft 7 are mutually constrained in the rotational circumference, the rotating cylinder 4 drives the reticle adjustment shaft 7 to rotate together. During installation, the rotation axes of the indicator drum 1 and the rotating cylinder 4 should coincide. A fixing cylinder 6 is provided between the indicator drum 1 and the rotating cylinder 4. The fixing cylinder 6 is a hollow cylindrical structure and is coaxially engaged with the indicator drum 1. The inner and outer surfaces of the bottom of the fixing cylinder 6 are respectively provided with inner and outer connecting threads. The outer connecting thread is used for fixing the fixing cylinder 6 to an external device, and the inner connecting thread is used for rotating the fixing cylinder 6 to the reticle adjustment shaft 7. The reticle adjustment shaft 7 is a columnar structure with a square top. The shortest side of the square structure 701 at the top is larger than the maximum radial dimension of the columnar structure, so that when the square structure 701 is engaged with the square hole 403, the columnar structure of the reticle adjustment shaft 7 does not contact the inner wall of the rotating cylinder 4. During installation, the reticle adjustment shaft 7 is inserted into the square hole 403 at the bottom of the rotating cylinder 4. The reticle adjustment shaft 7 is mutually restrained in the rotational circumferential direction by engaging with the square hole 403 at the bottom of the rotating cylinder 4 through the square structure 701 at the top. The outer surface of the columnar part of the reticle adjustment shaft 7 has a connecting thread that engages with the thread on the inner surface of the bottom of the fixed cylinder 6. The reticle adjustment shaft 7 and the fixed cylinder 6 are rotatably connected through the internal thread at the bottom of the fixed cylinder 6. When the reticle adjustment shaft 7 rotates, it can achieve a telescopic function relative to the fixed cylinder 6. During installation, the rotation axes of the indicator drum 1, the rotating cylinder 4, the fixed cylinder 6, and the reticle adjustment shaft 7 need to be aligned and sleeved together. The high-precision sight reticle adjustment device with locking function also includes a reticle adjustment shaft locking device, such as... Figure 2 and Figure 5 As shown, in order to realize the locking function of the reticle adjustment shaft, the inner surface of the rotating cylinder 4 is provided with threads and holes 402 that cooperate with the locking device of the reticle adjustment shaft. At the same time, the inner surface of the fixed cylinder 6 is provided with teeth 601, and the number of teeth 601 corresponds to the scale lines on the indicator drum 1.

[0025] The locking device for the graduated adjustment shaft includes a locking handwheel 2 and a locking pin 3. The locking handwheel 2 has a disc-shaped structure with threaded holes on its circumference and bottom. To make the locking handwheel 2 easy to turn, its circumference can be machined into an uneven shape to increase the friction with the hand during turning, such as a corrugated shape. The locking pin 3 is a cylindrical structure with a tapered bottom, the tapered shape pointing towards the inside of the rotating cylinder 4. The outer surface of the cylindrical locking pin 3 is provided with external threads that mate with the threads on the inner surface of the rotating cylinder 4 and the threaded holes at the bottom of the locking handwheel 2. During installation, the locking pin 3 is tightened into the threaded holes at the bottom of the locking handwheel 2, and the locking pin 3 and the locking handwheel 2 are fixedly connected by handwheel set screws 9 inserted into the circumferential threaded holes of the locking handwheel 2. When the user turns the locking handwheel 2, the locking pin 3 rotates synchronously with the handwheel 2 under the action of the handwheel set screw 9. Under the action of the external thread that engages with the rotating cylinder 4, the locking pin 3 moves up and down relative to the rotating cylinder 4. It should be noted that when turning the locking handwheel 2, the user should simultaneously grip the indicator drum 1 to keep both the indicator drum 1 and the rotating cylinder 4 in a non-rotating state. The locking device for the reticle adjustment shaft also includes a click pin 5 and a spring 13. One end of the spring 13 is fixedly installed on the inner wall of the rotating cylinder 4 opposite the hole 402, and the other end of the spring 13 is sleeved with the click pin 5. The click pin 5 is a cylindrical structure with one tapered end, its tapered portion extending out of the rotating cylinder 4 through the hole 402 and engaging with the click pin 5. Figure 5 The toothed grooves 601 on the inner surface of the fixed cylinder 6 shown engage with each other. The cylindrical structure of the click pin 5 is also provided with an annular groove 501 that engages with the conical bottom of the locking pin 3, as shown. Figure 7 As shown. In use, the user turns the locking handwheel 2, and the locking pin 3 rotates downward. When the cone at the bottom of the locking pin 3 engages with the annular groove 501 of the click pin 5, the click pin 5 cannot move to the right. The cone part of the click pin 5 is locked in the toothed groove 601 on the inner surface of the fixed cylinder 6. Neither the rotating cylinder 4 nor the indicator drum 1 can rotate. At this time, the gradation adjustment shaft 7 is fixed and locked.

[0026] This utility model discloses a high-precision sight reticle adjustment device with locking function, which also includes a pressure cap 8. The pressure cap 8 is disposed on the top of the fixed cylinder 6, and the inner surface of the pressure cap 8 and the outer surface of the fixed cylinder 6 have mutually mating threads. The pressure cap 8 and the fixed cylinder 6 are fixedly connected by threads. The function of the pressure cap 8 is to prevent axial displacement of the rotating cylinder 4 during rotation, ensuring precise adjustment of the reticle adjustment shaft 7.

[0027] To prevent external moisture, dust, impurities, and other contaminants from entering the device and reducing its adjustment accuracy or even damaging it, this invention can also include a sealing ring 12. The sealing ring 12 is circular and is fixedly engaged in the gap between the fixed cylinder 6 and the rotating cylinder 4. To protect the rotating components of the adjustment device, the sealing ring 12 should preferably be made of a soft material with a hardness lower than that of the rotating components it contacts, such as rubber or silicone.

[0028] This invention can also reduce weight by machining the interior of the reticle adjustment shaft 7 into a hollow structure, thereby reducing the overall weight of the scope and making it easier to carry.

[0029] This utility model discloses a high-precision sight reticle adjustment device with locking function, which also includes a pin limiting screw 11. The pin limiting screw 11 is a cylindrical structure with a tapered end. The pin limiting screw 11 is placed in a hole 401 on the upper side wall of the rotating cylinder 4, which communicates with the internal hollow structure, and is threadedly connected to the hole 401. During installation, the tapered end face of the pin limiting screw 11 protrudes from the inner wall surface of the rotating cylinder 4 and points inward into the rotating cylinder 4. To enable the pin limiting screw 11 to limit the axial movement of the locking pin 3, the cylindrical part of the locking pin 3 is provided with a protruding annular structure 301, such as... Figure 6 As shown. During installation, the raised annular structure 301 is placed below the hole 401. To enable the locking pin 3 to move circumferentially relative to the rotating cylinder 4, the outer surface of the raised annular structure 301 of the locking pin 3 has threads that mate with the inner surface of the rotating cylinder 4. In use, when the locking pin 3 moves a certain distance away from the rotating cylinder 4, the raised annular structure 301 will engage with the tapered end face of the limiting screw 11, preventing the locking pin 3 from further disengaging from the rotating cylinder 4. At this time, the limiting screw 11 acts as a limit for the locking pin 3, preventing the locking handwheel 2 and the locking pin 3 from separating from the device due to over-tightening.

[0030] The working principle of this utility model is as follows: The user adjusts the extension and retraction of the reticle adjustment shaft 7 by turning the indicator drum 1, thereby adjusting the position of the reticle plate inside the scope connected to the reticle adjustment shaft 7. After the position of the reticle plate is adjusted, the locking handwheel 2 is turned. The locking handwheel 2 drives the locking pin 3 to rotate. The locking pin 3 moves axially toward the hollow structure inside the rotating cylinder 4 until the conical part of the locking pin 3 engages with the annular groove 501 of the click pin 5. The click pin 5 can no longer move toward the spring 13 side, and the conical part of the click pin 5 is locked in the toothed groove 601 on the inner surface of the fixed cylinder 6. Figure 8 As shown, at this time, the rotating cylinder 4 cannot rotate, the extension and retraction of the reticle adjustment shaft 7 is fixed and cannot be adjusted, thus the position of the reticle plate inside the scope connected to the reticle adjustment shaft 7 is fixed, and the device is in a locked state.

[0031] When unlocking is required, the locking handwheel 2 is rotated in the reverse direction. The locking handwheel 2 drives the locking pin 3 to move axially in the direction of disengaging from the rotating cylinder 4 until the conical part of the locking pin 3 is no longer in contact with the annular groove 501 of the click pin 5. At this time, although the conical part of the click pin 5 is still in the toothed groove 601 on the inner surface of the fixed cylinder 6, the click pin 5 can move freely towards the spring 13. Therefore, when the user turns the indicator drum 1, the indicator drum 1 drives the rotating cylinder 4 and the click pin 5 inside it to rotate. When the conical part of the click pin 5 is obstructed by the protrusion of the toothed groove 601, the click pin 5 can move towards the spring 13, thereby... The conical part breaks through the obstruction, and the spring 13 is compressed to store elastic force. When the conical part of the click pin 5 rotates to the recessed part of the toothed groove 601, the compressed spring 13 releases its elastic force, causing the click pin 5 to move towards the side of the spring 13. During the continuous rotation of the rotating cylinder 4, the click pin 5, under the action of the protruding and recessed parts of the toothed groove 601 on the inner surface of the fixed cylinder 6, reciprocates along the axial direction by relying on the elastic force of the spring 13. At this time, the indicator drum 1 can rotate freely under the operation of the user, thereby adjusting the extension and retraction length of the reticle adjustment shaft 7, and then adjusting the position of the reticle plate inside the scope connected to the reticle adjustment shaft 7. The device is in the unlocked state.

[0032] In addition, when the conical part of the rotating click pin 5 switches one tooth of the tooth groove 601, the click pin 5 will make a clicking sound due to the contact between its conical part and the tooth groove 601. The user can identify the number of forward or backward gears of the indicator drum 1 by the clicking sound, which makes it convenient for the user to quickly adjust the device.
