[0030] Referring to Figures 1 and 2, the aiming device according to an embodiment of the present application includes a sight 1 (first device) and a connection structure. As shown in Figure 1, the connection structure includes a first connection component 2, a quick-clip component 3, and a second connection component 4. The first connection component 2 is fixed to the bottom of the sight 1, and the second connection component 4 is fixed to the top of the aiming device (second device). The quick-clip component 3 serves as an intermediate component, one side of which is used for detachable connection with the first connection component 2, and the other side of which is used for detachable connection with the second connection component 4. During use, the quick-clip component 3 and the second connection component 4 can be fixed to the top of the firearm after being assembled, without having to be disassembled each time. Similarly, the first connection component 2 can also be assembled with the aiming device without having to be disassembled each time. Therefore, when installing the aiming device on a firearm, only the first connection component 2 and the quick-clip component 3 need to be installed and fixed.

[0031] As shown in Figure 4, the first connecting component 2 includes a leather rail 21 and a first magnetic portion 22 provided on the leather rail 21. The leather rail 21 of this embodiment includes a first main body portion 211 and a second main body portion 212, and the width of the first main body portion 211 is smaller than the width of the second main body portion 212. A groove (not shown) is provided on the surface of the first main body portion 211 facing the quick-clamp component 3, and the groove is used to accommodate the first magnetic portion 22. The first magnetic portion 22 can be fixedly connected to the leather rail 21 by bonding, connecting with a connector (such as a bolt), etc. Two countersunk holes are provided on the second main body portion 212, and the two countersunk holes are spaced apart along the length direction of the leather rail 21. The countersunk holes are used to pass bolts to fix the first connecting component 2 and the sight 1 through the bolts. A limiting groove 2122 is provided between the two countersunk holes, and the limiting groove 2122 is opened along the width direction of the leather rail 21.

[0032] As shown in Figure 5, the quick-clamp assembly 3 includes a fixing base 32, a mounting slot 323 defined in the fixing base 32, a second magnetic portion 33 disposed within the mounting slot 323, and a self-luminous guide portion 34. The second magnetic portion 33 is used to attract the first magnetic portion 22 to secure the first connecting component 2 within the mounting slot 323; the self-luminous guide portion 34 is used to illuminate to indicate the position of the mounting slot 323.

[0033] The mounting slot 323 extends inward from the sidewall at one longitudinal end of the mounting base 32 and extends along the length of the mounting base 32, forming a slot structure with one end open. The second magnetic portion 33 is cylindrical in shape. A second magnetic portion mounting slot (not shown) is provided near the end of the mounting slot 323 distal from the open end. The second magnetic portion 33 is secured within the second magnetic portion mounting slot by bonding or by a connector. For example, a countersunk hole can be provided in the second magnetic portion 33, and the second magnetic portion 33 and the mounting base 32 can be threadedly connected by bolts. The self-luminous guide portion 34 has an annular cross-section and is disposed outside the second magnetic portion 33. The self-luminous guide portion 34 is made of a fluorescent material, such as a mixed injection molding of plastic and fluorescent powder. The self-luminous guide portion 34 can be secured to the mounting base 32 by bonding or other means. The self-luminous guide portion 34 is made of a fluorescent material and can illuminate at night or in low-light environments, thereby providing a guide for the approximate orientation of the mounting slot 323 and facilitating installation and alignment. The self-luminous guiding portion 34 is manufactured by injection molding of plastic and phosphor powder, which can improve the lifespan and light uniformity of the self-luminous guiding portion 34 .

[0034] The first magnetic attraction portion 22 is a magnet, and the second magnetic attraction portion 33 is a magnet or a magnetophilic metal; or, the first magnetic attraction portion 22 is a magnet or a magnetophilic metal, and the second magnetic attraction portion 33 is a magnet. Specifically, as long as the first magnetic attraction portion 22 and the second magnetic attraction portion 33 can attract and fix each other, the specific material and structure are not limited. For example, the magnetophilic metal can be cast iron. The second magnetic attraction portion 33 is used to attract the first magnetic attraction portion 22 to fix the first connecting component 2 to the preset position of the mounting groove 323. That is to say, when the fixing seat 32 is a magnetophilic metal, the first magnetic attraction portion 33 can only be a magnet.

[0035] The quick-clamp assembly 3 also includes a first clamping device 31. The first clamping device 31 is a quick-clamping device that can meet the impact requirements when using the aiming device and has excellent stability. The first clamping device 31 includes a clamping wrench 311, a limit screw 312, a clamping block 313, and an adjustment nut 314. Mounting holes 321 are respectively provided on the fixing seat 32 on both sides of the width direction of the mounting slot 323. The mounting holes 321 are used to pass the limit screws 312. The limit screw 312 includes a square rod 3121 and a threaded rod (not shown). The end of the square rod 3121 located outside the mounting hole 321 is hinged to one end of the clamping wrench 311, and the end of the threaded rod located outside the mounting hole 321 is threadedly connected to the adjustment nut 314. The clamping block 313 is arranged on the threaded rod inside the adjustment nut 314. The limit slot 2122 of the first connecting assembly 2 is used to accommodate the square rod 3121. When the free end of the clamping wrench 311 is rotated toward the fixing base 32, it drives the clamping block 313 to move toward the clamping wrench 311, thereby clamping the first connecting assembly 2 within the mounting groove 323. A spring member (not shown) may also be provided on the clamping block 313. The elastic force of the spring member is used to maintain the clamping block 313 in contact with the adjusting nut 314. The adjusting nut 314 is used to adjust the tightness of the first clamping device 31.

[0036] A latching groove 324 is provided on the sidewall of the mounting slot 323 near the clamping wrench 311. A corresponding abutment portion 2121 is provided on the first connecting assembly 2. When abutting against the latching groove 324, the abutment portion 2121 serves to limit the vertical displacement of the first connecting assembly 2 along the bottom surface of the mounting slot 323. In this embodiment, the latching groove 324 is a V-shaped groove extending from the sidewall of the mounting slot 323 toward the clamping wrench 311. The abutment portion 2121 is a convex structure that mates with the groove surface of the V-shaped groove. When the abutment portion 2121 engages the latching groove 324, the clamping device tightens the leather rail 21, thereby securely connecting the first connecting assembly 2 and the quick-clamp assembly 3.

[0037] To facilitate the leather rail 21 to enter the installation groove 323, a sloped guide structure 322 can also be provided on the fixed seat 32 circumferentially of the second magnetic portion 33. The sloped guide structure 322 gradually decreases in height from the side away from the installation groove 323 to the side close to the installation groove 323, that is, the sloped guide structure 322 is an inclined surface inclined toward the installation groove 323, forming a funnel-like shape, so that the leather rail 21 can easily enter the installation groove 323, thereby improving the convenience of installation.

[0038] As shown in Figures 2 and 6, the second connecting component 4 includes a connecting block 42 and a second clamping device 41. A connecting block mounting groove 325 is provided on the surface of the fixing seat 32 on the side facing away from the mounting groove 323. The connecting block mounting groove 325 can be a through groove provided along the length direction of the fixing seat 32. The structure of the second clamping device 41 is the same as that of the first clamping device 31 and will not be described in detail. The installation method between the connecting block 42, the second clamping device 41 and the connecting block mounting groove 325 is the same as the connection method between the leather rail 21, the first clamping device 31 and the mounting groove 323 and will not be described in detail. A through hole or a threaded hole is provided on the connecting block 42. By inserting a bolt into the through hole or the threaded hole, the connecting block 42 and equipment such as a firearm can be fixedly connected, thereby fixing the first connecting component 2, the quick clamping component 3 and the second connecting component 4 together to achieve the connection between the sight and the firearm.

[0039] The installation process of the connection structure of this embodiment is as follows: First, the first connecting assembly 2 is fixedly connected to the sight 1, and the quick-clamp assembly 3 and the second connecting assembly 4 are fixedly connected to the firearm (not shown). At this point, the sight 1 can be used as a standalone handheld device. When the sight 1 needs to be installed on the firearm, the self-luminous guide portion 34 is used to roughly determine the position of the mounting slot 323. The leather rail 21 at the bottom of the sight 1 is aligned with the mounting slot 323. Through the mutual attraction of the first and second magnetic portions 22 and 33, and the guidance of the inclined guide structure 322, the leather rail 21 is quickly installed into the mounting slot 323. The limiting groove 2122 of the leather rail 21 engages the square rod 3121 of the limiting screw 312. At this point, the free end of the clamping wrench 311 is moved toward the fixing base 32, causing the clamping block 313 to clamp the leather rail 21, completing the installation.

[0040] The connection structure of the embodiment of the present application is convenient for users to install when using it at night or in low-light environments. The self-luminous guide part emits light to provide rough directional guidance, which makes it convenient for users to quickly find the installation location. The first connecting component and the quick-clamp component are initially fixed by magnetic attraction. At this time, the inclined guide structure facilitates the first connecting component to quickly enter the installation slot and be attracted and fixed by the first magnetic attraction part. The limiting slot of the first connecting component is inserted into the square rod of the limiting screw. By pulling the clamping wrench, the clamping block can clamp the leather rail. The abutting part of the leather rail abuts the slot to complete the installation of the first connecting component and the quick-clamp component, so that the sight is fixed to the firearm. The connection structure of the present application does not require other connecting parts when the first connecting component and the quick-clamp component are installed and fixed, and the sight can be quickly and accurately installed on the firearm through multiple guidance, guiding and other structures, thereby improving the user's experience when using it at night.
