Description

Technical Field

[0001] This utility model relates to the field of aiming scopes, and more particularly to a miniaturized infrared red dot fusion aiming scope. Background Technology

[0002] A red dot sight, also known as a reflex sight or internal red dot sight, is a type of optical sight without magnification. It uses a red dot that illuminates the eye with white light, but its night vision display and red dot light source are similar. Because the point of light entering the eye in a red dot sight is always aligned with the red dot itself, accurate aiming is possible even if the eye is not on the central axis of the sight. This improves shooting accuracy during high-speed movement or when the body is swaying, and therefore it is widely used in military firearms and even in the head-up displays of fighter jets. Currently, most red dot sights can only be used in bright daylight or nighttime conditions; in low light and at night, the target is not clearly visible, resulting in poor aiming performance.

[0003] However, in actual use, the existing scope height adjustment function often fails to meet everyone's needs. When tall shooters use a scope, if the scope height is too low, it may cause excessive head tilting, tension in the neck and shoulder muscles, fatigue during prolonged shooting, and even affect shooting accuracy. For example, a shooter who is 1.9 meters tall may need to bend over and hunch over to align their eye with the eyepiece of a standard-height scope. This posture is not only uncomfortable but also reduces body stability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a miniaturized infrared red dot fusion sight, which aims to solve the problem that "the height adjustment function of existing sights is often difficult to meet the needs of everyone".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a miniaturized infrared red dot fusion sight, including a base, a connecting box fixedly connected to the top of the base, a red dot fusion sight disposed on the top of the connecting box, an adjustment mechanism disposed inside the connecting box, and a limit mechanism disposed on the adjustment mechanism;

[0006] The adjusting mechanism includes a bearing, the outer wall of which is fixedly connected to the inner wall of the connecting box. A bidirectional screw is rotatably connected to the inner wall of the bearing. A knob is fixedly connected to the extension end of the bidirectional screw. A threaded sleeve is threadedly connected to the outer wall of the bidirectional screw. A connecting block is fixedly connected to the outer wall of the threaded sleeve. A connecting rod is hinged to the top of the outer wall of the connecting block. A base plate is fixedly connected to the top of the connecting rod.

[0007] As a further description of the above technical solution: a damping telescopic rod is fixedly connected to the top of the connecting box, and the top of the damping telescopic rod is fixedly connected to the bottom of the base plate.

[0008] As a further description of the above technical solution: there are two sets of connecting rods and damping telescopic rods, with the two sets of connecting rods symmetrically arranged at the left and right ends of the bidirectional screw, and the damping telescopic rods symmetrically arranged at the front and rear ends inside the connecting box.

[0009] As a further description of the above technical solution: the limiting mechanism includes a chuck, the outer wall of the chuck is fixedly connected to the outer wall of the connecting box, and the inner wall of the chuck is fixedly connected with teeth.

[0010] As a further description of the above technical solution: a spring is fixedly connected to the inner wall of the knob, and a locking block is fixedly connected to the upper extension end of the spring.

[0011] As a further description of the above technical solution: the outer wall of the knob is provided with a sliding groove, the outer wall of the locking block is fixedly connected with a locking rod, and the outer wall of the locking rod is slidably connected to the sliding groove.

[0012] As a further description of the above technical solution: the inner wall of the card block is inserted into the outer wall of the tooth, and the tooth is triangular in shape.

[0013] As a further description of the above technical solution: the bottom of the red dot fusion sight is detachably connected to the top of the base plate by bolts.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rotation of the knob drives the bidirectional screw to rotate, and the threaded sleeve moves inward synchronously under the action of the bidirectional screw, driving the connecting rod to move smoothly upward, so as to realize the fine adjustment of the height of the red dot fusion sight. It can adapt to the needs of different shooting scenarios. In addition, the damping telescopic rods symmetrically arranged at the bottom of the base plate extend and retract synchronously during height adjustment, which not only provides stable support for the sight, but also effectively buffers the vibration generated during firearm firing, ensuring the stability of the aiming crosshair and improving shooting accuracy.

[0016] 2. In this utility model, the triangular teeth in the limiting mechanism correspond to different height settings. After pulling the lever to disengage the locking block from the teeth, the knob can be quickly rotated to the target height. Releasing the lever causes the spring to push the locking block back into the teeth, locking the bidirectional screw and preventing adjustment displacement during firing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3This utility model provides an embodiment of a miniaturized infrared red dot fusion sight, including a base 1 for mounting on a firearm or other carrier, providing basic support. A connecting box 2 is fixedly connected to the top of the base 1, serving as the mounting carrier for an adjustment mechanism 6 and housing internal transmission components. A red dot fusion sight 5 is mounted on the top of the connecting box 2 for target aiming and infrared fusion observation. An adjustment mechanism 6 is located inside the connecting box 2, enabling height adjustment and stable support of the sight. The adjustment mechanism 6 has a limited... Positioning mechanism 7 and limiting mechanism 7 are used to lock the adjusted height position to prevent loosening. Adjustment mechanism 6 includes bearing 611. Bearing 611 is engaged with double-ended screw 612 through inner ring and fixed housing through outer ring to achieve stable rotation of screw. The outer wall of bearing 611 is fixedly connected to the inner wall of connecting box 2. Double-ended screw 612 is rotatably connected to the inner wall of bearing 611. Double-ended screw 612 drives the two threaded sleeves 613 on both sides to move synchronously through double-ended thread to realize the lifting and lowering of base plate 3. Knob 617 is fixedly connected to the extension end of double-ended screw 612. Knob 617 is used for manual adjustment. The component drives a screw to rotate. A threaded sleeve 613 is threadedly connected to the outer wall of the bidirectional screw 612. The threaded sleeve 613 cooperates with the bidirectional screw 612 to convert rotational motion into linear movement. A connecting block 614 is fixedly connected to the outer wall of the threaded sleeve 613. The connecting block 614 connects the threaded sleeve 613 and the connecting rod 615, transmitting the moving power. The connecting rod 615 is hinged to the top of the outer wall of the connecting block 614. The connecting rod 615, through the hinge structure, converts the horizontal movement of the threaded sleeve 613 into the vertical lifting and lowering of the base plate 3. The top of the connecting rod 615 is fixedly connected to the base plate 3. 3 serves as the mounting base for the scope, bearing its weight and transmitting adjustment displacement. A damping telescopic rod 616 is fixedly connected to the top of the connecting box 2. The damping telescopic rod 616 buffers vibration through its damping characteristics and also assists in supporting the lifting and lowering of the base plate 3. The top of the damping telescopic rod 616 is fixedly connected to the bottom of the base plate 3. There are two sets of connecting rods 615 and damping telescopic rods 616. The two sets of connecting rods 615 are symmetrically arranged at the left and right ends of the bidirectional screw 612. The symmetrical layout ensures the balance and stability of the adjustment process. The damping telescopic rods 616 are symmetrically located at the front and rear ends inside the connecting box 2.

[0025] Reference Figure 1 , Figure 4The limiting mechanism 7 includes a chuck 711, which serves as the mounting base for the teeth 712 and is fixed to the outer wall of the connecting box 2 to provide a positioning reference. The outer wall of the chuck 711 is fixedly connected to the outer wall of the connecting box 2, and the inner wall of the chuck 711 is fixedly connected to the teeth 712, which are triangularly distributed and cooperate with the locking block 714 to achieve a gear-type positioning lock. The inner wall of the knob 617 is fixedly connected to a spring 713, which provides a return force to the locking block 714 to ensure automatic locking after adjustment. The upper extension end of the spring 713 is fixedly connected to the locking block 714. When the locking block 714 engages with the teeth 712, it restricts the rotation of the screw; when disengaged, it allows adjustment operation. The outer wall of the knob 617 has a sliding groove. The lever 715 provides a sliding track to guide the locking block 714 to move up and down. The lever 715 is fixedly connected to the outer wall of the locking block 714. The lever 715 serves as an operating component, and manual pulling enables the locking block 714 to engage and disengage with the tooth 712. The outer wall of the lever 715 is slidably connected to the slide groove. The inner wall of the locking block 714 is inserted into the outer wall of the tooth 712. The insertion structure achieves mechanical locking after adjustment to prevent accidental rotation. The tooth 712 is triangular in shape, which facilitates the quick engagement and disengagement of the locking block 714, improving adjustment efficiency. The bottom of the red dot fusion sight 5 is detachably connected to the top of the base plate 3 by bolts 4. Bolts 4 are used to achieve a detachable connection between the sight and the base plate 3, facilitating disassembly, assembly, and maintenance.

[0026] Working principle: A connecting box 2 is installed on the base 1. An adjustment mechanism 6 is set inside the connecting box 2. When the basic height of the red dot fusion sight 5 needs to be adjusted, the knob 617 is manually turned. The knob 617 drives the double screw 612 to rotate. When the double screw 612 rotates, it drives the two threaded sleeves 613 connected to the outer wall to move inward at the same time. This drives the connecting rod 615 at the top to move inward, causing the base plate 3 connected to the top to rise. This allows the red dot fusion sight 5 to be adjusted in height. At the same time, a damping telescopic rod 616 is installed at the bottom of the base plate 3. When the base plate 3 rises, it drives the damping telescopic rod 616 to rise as well. This ensures the stability of the red dot fusion sight 5 after height adjustment and has a certain vibration damping effect on the firearm.

[0027] When adjusting the angle, the operator can rotate the tooth 712 to adjust it according to different angles. The position of the tooth 712 corresponds to the height position after the operator adjusts the screw. When the knob 617 is rotated to the position of different teeth 712, the red dot fusion sight 5 is quickly adjusted to the corresponding height. At the same time, during adjustment, the locking lever 715 needs to be manually pulled down. The locking lever 715 drives the top locking block 714 to move down. When the locking block 714 moves down, it disengages from the tooth 712. After the angle is adjusted, the locking lever 715 is loosened. Under the action of the spring 713, the locking block 714 returns to its original position and engages with the outer wall of the tooth 712, thereby limiting and fixing the bidirectional screw 612.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
