Abstract
Description
Technical Field
[0001] This utility model relates to the field of sky-canopy target speed measurement technology, specifically a sky-canopy target rapid erection device. Background Technology
[0002] In firearm velocity testing, when using a canopy target, at least three people are needed to measure the target distance using a steel tape measure and a plumb bob. The setup time is approximately 30 minutes. To ensure that the two targets are directly below the ballistic trajectory, the shooter needs to aim at the target using mechanical sights. However, due to visual errors, there is a certain deviation in the left and right orientation of the target, which may cause the bullet to not pass directly above the canopy target, preventing the canopy target from triggering properly. This requires correction and re-setting the canopy target, resulting in low testing efficiency. When using a steel tape measure for long-distance ranging, there is a certain error due to the influence of gravity and weather. The target distance is an important parameter for accurately determining the velocity measurement point. Inaccurate target distance measurement leads to inaccurate final velocity data. Therefore, a laser rangefinder is needed to replace human vision to reduce deviations. Furthermore, the laser rangefinder can measure the distance between the muzzle and the canopy target.
[0003] Based on this, a rapid target erection device for sky-canopy targets is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] In one embodiment, such as Figures 1-5 As shown, the rapid target erection device for the dome target includes a fixed base 1, a gantry frame 16, and a dome target 18. The inner wall of the fixed base 1 is threaded with a fixing bolt 11. The upper surface of the fixed base 1 is threaded with a fixing frame 12 via the fixing bolt 11. A laser rangefinder 4 is installed on the inner wall of the fixing frame 12. A fixing plate 13 is attached to the lower surface of the fixed base 1. The outer wall of the gantry frame 16 has a through hole, and a plumb bob 17 is installed in the through hole. The plumb bob 17 is located directly above the dome target 18. The inner wall of the fixing frame 12 is provided with a fixing mechanism 2, and the inner wall of the fixing plate 13 is provided with an auxiliary mechanism 3.
[0026] In this embodiment, the laser rangefinder 4 can be quickly fixed by the fixed frame 12 in conjunction with the fixed mechanism 2. Then, the fixed frame 12 and the laser rangefinder 4 can be fixed on the gun barrel by the cooperation between the fixed base 1, the fixed plate 13 and the pin bolt 14. During the fixing process, the auxiliary mechanism 3 can ensure the stability of the laser rangefinder 4 during fixing and avoid the laser rangefinder 4 from shifting during fixing, which would affect subsequent testing.
[0027] In an optional embodiment, such as Figure 2 and Figure 3As shown, the inner wall of the fixing seat 1 away from the fixing bolt 11 is threaded with a pin bolt 14, and the outer wall of the fixing plate 13 is provided with a through hole that matches the outer wall of the pin bolt 14. The fixing seat 1 and the fixing plate 13 can be fixed by the pin bolt 14. At the same time, the distance between the fixing seat 1 and the fixing plate 13 can be adjusted when the pin bolt 14 is connected to the fixing seat 1.
[0028] In an optional embodiment, such as Figure 3 As shown, an elastic element 15 is fixedly connected to the inner cavity of the fixed plate 13. The elastic element 15 consists of a damper and a spring. When adjusting the distance between the fixed seat 1 and the fixed plate 13, the fixed plate 13 will automatically move downward under the action of the elastic element 15.
[0029] In an optional embodiment, such as Figure 3 As shown, a circular groove is provided on the outer wall of the fixing base 1. The position of the circular groove corresponds to the elastic element 15, and the diameter of the circular groove is 20-30mm larger than the diameter of the elastic element 15, so that the elastic element 15 can expand and contract within the circular groove without being interfered with.
[0030] In an optional embodiment, such as Figure 3 and Figure 4 As shown, the fixing mechanism 2 includes a bidirectional threaded rod 21. The outer wall of the bidirectional threaded rod 21 is rotatably connected to the inner wall of the fixing frame 12. A slider 22 is symmetrically threaded onto the outer wall of the bidirectional threaded rod 21. The outer wall of the slider 22 is slidably connected to the inner wall of the fixing frame 12. A connecting block 23 is fixedly connected to the top of the slider 22. The outer wall of the connecting block 23 is slidably connected to the inner wall of the fixing frame 12. A clamping plate 24 is fixedly connected to the top of the connecting block 23. The outer wall of the clamping plate 24 is slidably connected to the inner wall of the fixing frame 12. The outer wall of the clamping plate 24 contacts the outer wall of the laser rangefinder 4. Rotating the bidirectional threaded rod 21 causes the slider 22 to move on the outer wall of the bidirectional threaded rod 21. The slider 22 drives the connecting block 23 to move synchronously. The connecting block 23 drives the clamping plate 24 to move synchronously, so that the clamping plate 24 clamps and fixes the laser rangefinder 4, and at the same time, the laser rangefinder 4 is in the center position, which facilitates subsequent installation work.
[0031] In an optional embodiment, such as Figure 3 and Figure 4 As shown, guide rods 25 are symmetrically distributed on the outer wall of the clamping plate 24. The outer wall of the guide rods 25 is slidably connected to the inner wall of the fixed frame 12. The guide rods 25 limit and guide the clamping plate 24 so that the clamping plate 24 will not deviate when it moves, and at the same time avoid the clamping plate 24 from moving too far.
[0032] In an optional embodiment, such as Figure 2 and Figure 4As shown, the auxiliary mechanism 3 includes a first support rod 31 and a second support rod 32. A rotating rod 33 is fixedly connected to the inner wall of the first support rod 31 and the second support rod 32 at symmetrical positions. The outer wall of the rotating rod 33 is rotatably connected to the inner wall of the fixed plate 13. Rotating the first support rod 31 causes the rotating rod 33 to rotate, and at the same time rotating the second support rod 32 makes both the second support rod 32 and the first support rod 31 perpendicular to the fixed plate 13. Then, the bottom ends of the first support rod 31 and the second support rod 32 are brought into contact with the flat pad or tabletop to ensure the horizontal state of the laser rangefinder 4.
[0033] In an optional embodiment, such as Figure 3 and Figure 5 As shown, a locking block 34 is engaged with the inner wall of the rotating rod 33, and the outer wall of the locking block 34 is engaged with the inner wall of the fixing plate 13. The engagement part between the outer wall of the locking block 34 and the inner wall of the fixing plate 13 is hemispherical. A spring 35 is fixedly connected to the outer wall of the locking block 34, and the outer wall of the spring 35 is fixedly connected to the inner wall of the fixing plate 13. When the first support rod 31 and the second support rod 32 are rotated, the rotating rod 33 is driven to rotate synchronously, causing the locking block 34 to drive the spring 35 to contract. When the first support rod 31 drives the rotating rod 33 to rotate 90 degrees, under the action of the elastic force of the spring 35, the outer wall of the locking block 34 is engaged with the inner wall of the rotating rod 33 again. At this time, the first support rod 31 and the second support rod 32 can be rotated.
[0034] The above embodiments disclose a rapid target-setting device for a dome target. When installing the laser rangefinder 4 onto a firearm, the laser rangefinder 4 is first placed on the inner wall of the fixed frame 12. Then, the bidirectional threaded rod 21 is rotated, causing the slider 22 to move on the outer wall of the bidirectional threaded rod 21. The slider 22 drives the connecting block 23 to move synchronously, and the connecting block 23 drives the clamping plate 24 to move synchronously, so that the clamping plate 24 clamps and fixes the laser rangefinder 4, simultaneously placing the laser rangefinder 4 in the center position to facilitate subsequent installation. Then, the pin bolt 14 is tightened, causing the outer wall of the pin bolt 14 to rotate on the inner wall of the fixed seat 1. Subsequently, the pin bolt 14 continues to rotate, and the elastic element 1... Under the action of 5, the distance between the fixed seat 1 and the fixed plate 13 gradually increases. When the distance between the fixed seat 1 and the fixed plate 13 is sufficient, the tightening of the pin bolt 14 can be stopped. Then, the gun barrel is inserted between the fixed seat 1 and the fixed plate 13. Subsequently, the first support rod 31 is rotated, causing the first support rod 31 to drive the rotating rod 33 to rotate, causing the locking block 34 to drive the spring 35 to contract. When the first support rod 31 drives the rotating rod 33 to rotate 90 degrees, under the action of the elastic force of the spring 35, the outer wall of the locking block 34 is inserted into the inner wall of the rotating rod 33 again. At this time, the rotation of the first support rod 31 is stopped. Then, the second support rod 32 is rotated in the same way, so that the second support rod 32 is engaged with the first support rod. All 31 are perpendicular to the fixing plate 13. Then, the bottom ends of the first support rod 31 and the second support rod 32 are brought into contact with the flat pad or table to ensure the horizontal state of the laser rangefinder 4. Then, the pin bolt 14 is tightened to clamp the barrel between the fixing base 1 and the fixing plate 13, thus completing the fixation. Then, the height of the gantry 16 is adjusted so that the laser emitted by the laser rangefinder 4 passes through the perforation on the gantry 16. Then, the distance between the gantry 16 and the muzzle is adjusted. After the distance is appropriate, the plumb bob 17 is tied to the perforation so that the plumb bob 17 is directly above the canopy target 18. Then, the gantry 16 is moved again. After the movement, a second canopy is placed below the gantry 16. Target 18, ensuring the plumb bob remains directly above the canopy target 18. Then, the target support can be moved away, the two canopy targets 18 aligned, the target distance checked, and the power and signal cables connected. After completing all the assumptions, the canopy target test can begin. In summary, the laser rangefinder 4 can be quickly fixed using the fixing frame 12 and the fixing mechanism 2. Then, through the cooperation between the fixing base 1, the fixing plate 13, and the pin bolt 14, the fixing frame 12 and the laser rangefinder 4 can be fixed to the barrel. During the fixing process, the auxiliary mechanism 3 ensures the stability of the laser rangefinder 4 during fixing, preventing the laser rangefinder 4 from shifting during fixing and affecting subsequent tests.
