Description
Technical Field
[0001] This application relates to the field of auxiliary shooting devices, specifically an external connection structure and auxiliary device for a shooting instrument. Background Technology
[0002] Shooting devices, such as rifles, have relatively fixed basic functions. When users want to add auxiliary devices, they usually have to purchase dedicated components that are already equipped with the correct connection structure for the firearm. However, if a user wants to use the dedicated auxiliary device on different firearms, the connection may not be ideal. They may have to temporarily connect the device to the firearm by wrapping it with tape, which affects both the performance of the firearm and the functionality of the auxiliary device. Alternatively, they may need to purchase dedicated components with the same function but different connection structures for different firearms, which is costly for the user.
[0003] Therefore, an adapter structure compatible with different firearms is needed to solve the above problems. Utility Model Content

[0035] Please refer to Figure 1 - Figure 8 This embodiment provides an external attachment structure and auxiliary device for shooting equipment, applied to the housing 1 of the auxiliary device. The external attachment structure for shooting equipment includes:
[0036] The first alignment connection portion 110 is disposed on the outer wall of the housing 1;
[0037] A connection hole 120 is provided adjacent to the first alignment connection portion 110;
[0038] The connection hole 120 is also provided on the housing 1.
[0039] The adapter 2 has a second mating connection 210 at one end that mates with the first alignment connection 110; the other end of the adapter 2 has a matching connection 220, which is used to detachably connect different firearms.
[0040] Locking component 3, which passes through the adapter 2 and is detachably connected to the connecting hole 120.
[0041] Traditional firearms are generally composed of purely mechanical structures and do not integrate digital or electronic functional components. Auxiliary components, on the other hand, are usually digital or electronic functional components and come in a variety of forms, such as cameras, rangefinders, and lighting devices.
[0042] The working principle of the external attachment structure of this shooting device is as follows:
[0043] The housing 1 is the outer shell or box of the auxiliary device, and it is provided with a first alignment connection part 110. The adapter 2 is matched and aligned with the first alignment connection part 110 through the second docking connection part 210. This kind of pre-connection also has the functions of positioning and limiting after connection, which has a good connection accuracy guarantee. Of course, it is also necessary to combine the dimensional processing accuracy of the housing 1, the first alignment connection part 110, the adapter 2, and the second docking connection part 210.
[0044] After the adapter 2 and the housing 1 are mated and engaged by the second mating connection 210 through the first alignment connection 110, the locking member 3 passes through the adapter 2 and the connection hole 120 to lock and fix the connection between the adapter 2 and the housing 1. Alternatively, the locking and fixing can be canceled for disassembly.
[0045] The matching connection part 220 provided at the other end of the adapter 2 is used for detachable connection to the connection structure of different firearms, so that the auxiliary device can be detachably connected to the connection structure of different firearms, realizing the switching of one auxiliary device to different models and specifications of firearms, reducing the user's hardware purchase cost, and avoiding the instability of connection by wrapping tape.
[0046] Please refer to Figure 1 and Figure 3 , Figure 6 The first alignment connection part 110 is a groove, and the second docking connection part 210 is a protrusion that docks with the groove.
[0047] Alternatively, the second docking connection part 210 may be a groove, and the first alignment connection part 110 may be a protrusion that docks with the groove.
[0048] In some embodiments, the housing 1 is a box with a generally rectangular parallelepiped structure, including a front end face, a rear end face, and four side faces. The first alignment connection part 110 is a long strip-shaped groove that can be disposed in three of the four side faces.
[0049] The connecting holes 120 are in pairs and are located on both sides of the elongated groove.
[0050] Please refer to Figure 4 - Figure 6 and Figure 9 The locking component 3 is a bolt, and the connecting hole 120 is a threaded hole.
[0051] Bolts are easy to procure, and the 120 threaded connection hole is easy to process. This disassembly and connection method is also easy to operate, and the connection structure technology is mature and stable.
[0052] Example 1
[0053] Please refer to Figure 3 and Figure 4 The matching connection part 220 includes a first pipe clamp 221 and a second pipe clamp 222 that is detachably connected to the first pipe clamp 221.
[0054] The first clamp 221 and the second clamp 222 are combined and can be fitted onto the cylindrical or tubular structure of a rifle, such as the scope tube or barrel of an optical sight.
[0055] Please refer to Figure 3 and Figure 4 The matching connection part 220 includes a connecting plate 223 that connects the first pipe clamp 221 and the adapter 2; the first pipe clamp 221 and the second pipe clamp 222 are detachably connected by bolts.
[0056] The length of the 223 connecting lever can be customized to meet different usage needs and avoid obstructing the user's aiming field of view.
[0057] Example 2
[0058] Please refer to Figure 7 and Figure 8 The matching connection part 220 is a connection clamp structure corresponding to the Picatinny rail or the dovetail rail.
[0059] The connecting clamp is designed for Picatinny rails or dovetail rails. Specifically, the mating connection part 220 includes a connecting plate 226 integrated with the adapter 2, with a receiving plate 227 on one side corresponding to the rail. The mating connection part 220 also includes a receiving block 228 separate from the connecting plate 226, corresponding to the other side of the rail. The receiving block 228 is detachably connected to the connecting plate 226 by bolts.
[0060] During connection, the receiving block 228 and the connecting plate 226 are located on the left and right sides of the guide rail, respectively, and then the three are locked and fixed with bolts. If the guide rail is a Picatinny guide rail, the receiving block 228 and the connecting plate 226 each contain receiving grooves corresponding to the two sides of the Picatinny guide rail, and the connecting plate 226 is also provided with a positioning strip 229 that extends into the groove formed by the horizontal strips on the upper end face of the Picatinny guide rail.
[0061] If the guide rail is a dovetail guide rail, then the receiving block 228 and the connecting plate 226 each include receiving grooves on both sides of the corresponding dovetail guide rail.
[0062] Example 3
[0063] Please refer to Figure 5 and Figure 6 , Figure 9 The adapter 2 is a plate, which includes a first support plate 230 and a second support plate 240. The first support plate 230 and the second support plate 240 are provided with an included angle. The second mating connection part 210 and the matching connection part 220 are respectively located on the first support plate 230 and the second support plate 240. The matching connection part 220 includes a mating anti-rotation part 224 protruding from the end face of the second support plate 240 and a bolt through hole 225 adjacent to the mating anti-rotation part 224 and penetrating the second support plate 240. The mating anti-rotation part 224 is used to extend into the M-LOK connecting groove 4.
[0064] The bolt passes through the bolt through hole 225 and the M-LOK connecting groove 4 to the corresponding nut hole, so that the adapter 2 is fastened to the M-LOK connecting groove 4, and the connection is completed.
[0065] In some embodiments, the angle between the first support plate 230 and the second support plate 240 is 90°, the cross-section of the plate is "L" shaped, and the inner surfaces of the first support plate 230 and the second support plate 240 respectively abut against the two sides of the housing 1.
[0066] The M-LOK connection slot 4 is a structure set on the M-LOK handguard. Through the above connection structure, auxiliary devices can be connected to firearms with M-LOK handguards.
[0067] Please refer to Figure 5 and Figure 6 , Figure 9 The anti-rotation part 224 consists of two symmetrically arranged crescent-shaped protrusions, with a gap between the two crescent-shaped protrusions; the bolt through hole 225 is located between the two crescent-shaped protrusions; the second support plate 240 has a recess 241 for receiving nuts on one end face away from the anti-rotation part 224; the recess 241 is connected to the bolt through hole 225.
[0068] The anti-rotation part 224 of this structure is simple and easy to manufacture, and can prevent relative rotation from occurring after the adapter 2 is assembled with the M-LOK handguard. At the same time, the nut is housed in the groove 241, which can prevent the second support plate 240 from being pushed against by the nut and not being able to fit well against the side of the housing 1.
[0069] Please refer to Figure 1 - Figure 8This utility model also provides an auxiliary device, including a shooting device external attachment connection structure as described above; it also includes a housing 1, a display screen 5, a control board 6, touch buttons 7, a horizontal information sensor 8, a timing module 9, a battery 10, and a user interface module 11; the display screen 5, control board 6, horizontal information sensor 8, timing module 9, and battery 10 are all disposed within the inner cavity of the housing 1; the housing 1 has a display area corresponding to the display screen 5; the touch buttons 7 protrude from the end face of the housing 1; the display screen 5, touch buttons 7, horizontal information sensor 8, timing module 9, user interface module 11, and battery 10 are electrically connected to the control board 6; The user interface module 11 includes a first interactive interface, a second interactive interface, and a third interactive interface that can be displayed on the display screen 5. The control board 6 controls the display screen 5 to turn off or switch to display any one of the first, second, or third interactive interfaces based on the pressure information of the touch button 7. The dynamic image displayed on the first interactive interface is connected in parallel with the data collected by the horizontal information sensor 8. The dynamic image displayed on the second interactive interface is connected in parallel with the data sent by the timing module 9. The dynamic image displayed on the third interactive interface is connected in parallel with the data collected by the horizontal information sensor 8 and the data sent by the timing module 9.
[0070] Working principle: The horizontal information sensor 8 can be a gyroscope, tilt sensor, accelerometer or other existing sensor to measure the tilt angle, so that this auxiliary device has the first function, which is an electronic level.
[0071] The timing module 9 is mainly used to call the preset program on the control board 6 after the user presses the touch button 7, so that the timing module 9 can work and the auxiliary device has a second function, which is an electronic timer.
[0072] The dynamic pattern displayed on the first interactive interface can be multiple rectangles with a first color that are set at equal intervals. When the horizontal information sensor 8 detects that the auxiliary device is placed horizontally, the control board 6 controls the GUI image stored in the user interface module 11 to display all the rectangles with the first color according to the sensor information.
[0073] When the horizontal information sensor 8 detects that the auxiliary device is tilted to the right, the control board 6, based on the sensor information, controls the GUI image stored in the user interface module 11 to display multiple equally spaced rectangular sections as rectangles of the second color. The greater the rightward tilt, the fewer of the multiple equally spaced rectangles will display the second color, turning them blank or black.
[0074] When the horizontal information sensor 8 detects that the auxiliary device has returned to a horizontal position, the control board 6, based on the sensor information, controls the GUI image stored in the user interface module 11 to display all the rectangles with the first color.
[0075] When the horizontal information sensor 8 detects that the auxiliary device is tilted to the left, the control board 6, based on the sensor information, controls the GUI image stored in the user interface module 11 to display multiple equally spaced rectangular sections as rectangles of the third color. The greater the leftward tilt, the fewer of the multiple equally spaced rectangles display the third color, turning them blank or black.
[0076] When the horizontal information sensor 8 detects that the auxiliary device has returned to a horizontal position, the control board 6, based on the sensor information, controls the GUI image stored in the user interface module 11 to display all the rectangles with the first color.
[0077] The first color can be green, and the second and third colors can be red and blue.
[0078] In addition, based on the first interactive interface, a split-screen display is also possible, with the remaining power of battery 10 displayed at the top of display screen 5 and multiple equally spaced rectangles displayed at the bottom of display screen 5.
[0079] In addition, the first interactive interface can also be two symmetrical cuboids displayed in full screen on the display screen 5. The same display rules as above can be used, except that once the horizontal information sensor 8 detects that the auxiliary device is tilted, one of the cuboids becomes blank or black.
[0080] In this mode, by pressing the touch button 7, the control panel 6 calls the corresponding program, and the user interface module 11 displays the preset GUI file, which then appears on the display screen 5.
[0081] The second interactive interface is a dynamic image display interface that is linked with the timing module 9. This is useful because some shooting competitions specify a certain number of bullets to be fired within a predetermined time. Similarly, some tactical operations involve many steps, each with a time limit, such as the duration of a conversation with teammates. In these cases, a countdown function is used. The touch button 7 receives pressed inputs and generates corresponding control commands. The control panel 6 then controls the timing module 9, causing the countdown's dynamic digital image to be displayed on the screen 5. This auxiliary device can also have a built-in speaker; when the countdown ends, the speaker emits a notification sound.
[0082] The third interactive interface is a combination of the aforementioned first and second interactive interfaces. The first and second interactive interfaces are displayed on the display screen 5 in a split screen, which can realize the synchronous operation of the level function and the countdown function.
[0083] Please refer to Figure 1 and Figure 2 It includes a battery cover 12, one end of which is rotatably connected to the housing 1; the other end of which is fixedly connected to the housing 1 by screws.
