In order to ensure the stability of the shooting experiment, a bracket needs to be used for assistance.

[0003] In the prior art, there are the following defects: when conducting shooting distance experiments, there was no fixator in the past, and it completely relied on manual shooting. However, there are many problems with manual shooting. The most prominent one is that the shooting angle will change, which greatly reduces the accuracy of the experimental results and reliable shooting data cannot be obtained. At the same time, the shooting distance is measured with a tape measure, and its accuracy is not high. It is easily affected by human measurement errors and environmental factors, and it is difficult to meet the requirements of high-precision shooting experiments. Therefore, a bracket for shooting distance experiments is proposed to solve the above problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figures 1 - 3, An embodiment provided by the present utility model: A support for shooting distance experiments, including a base 1. The top end of the base 1 is fixedly connected with a support rod 2. The base 1 can be installed on the shooting test bench by bolts, facilitating subsequent shooting experiments. The outer wall of the support rod 2 is slidably connected with a moving plate 10. The support rod 2 mainly plays a guiding role for the moving plate 10, enabling the moving plate 10 to move vertically along the support rod 2 without deviation in the moving trajectory. The top end of the moving plate 10 is hinged with a clamping plate 4 through a hinge rod 3. The clamping plate 4 can fix the experimental firearm to ensure that its muzzle angle will not change due to recoil. The top end of the support rod 2 is fixedly connected with a connecting seat 5. The experimental firearm can be placed on the connecting seat 5 for fixation. The bottom end of the connecting seat 5 is fixedly connected with a fixed tube 6. The outer wall of the fixed tube 6 is movably connected with a threaded sleeve 7. The threaded sleeve 7 can move vertically and rotate on the fixed tube 6. A positioning mechanism is provided on the inner wall of the threaded sleeve 7. A connecting component is provided on the left side wall of the connecting seat 5.

[0032] Refer to Figure 1 , Figure 4 And Figure 5 , The connecting component includes a support tube 11. The support tube 11 is fixedly connected to the left side wall of the connecting seat 5. The left end of the support tube 11 is fixedly connected with a connecting block 12. There are protruding parts on the inner wall of the connecting block 12, and it can be inserted and positioned with the mounting block 15 through the protruding parts. The right end inner wall of the connecting block 12 is elastically connected with a wedge block 14 through a positioning spring 13. The wedge block 14 has an inclined surface. When the inclined surface is squeezed, the wedge block 14 will move horizontally along the inner wall of the connecting block 12. The inner wall of the connecting block 12 is inserted with a mounting block 15. The left end of the mounting block 15 is fixedly connected with a laser rangefinder 16. The laser rangefinder 16 is an instrument that uses laser technology to measure distance. It is an existing technology and will not be elaborated here too much. The shooting distance can be accurately judged through the laser rangefinder 16 to reduce the generation of errors. The right end inner wall of the connecting block 12 is fixedly connected with one end of the positioning spring 13. When the wedge block 14 moves to the right, it will compress the positioning spring 13. When resetting, the elastic force of the positioning spring 13 is used to drive the wedge block 14 to reset. The other end of the positioning spring 13 is fixedly connected with the inner side wall of the wedge block 14. The wedge block 14 penetrates and is slidably connected to the inner wall of the connecting block 12. The connecting block 12 is provided with a notch corresponding to the wedge block 14 to meet the sliding of the wedge block 14 on the inner wall of the connecting block 12. The left end of the wedge block 14 is in contact with the outer wall of the mounting block 15.

[0033] Refer to Figures 1 - 3, the top end of the moving plate 10 is hinged to one end of the hinge rod 3. Since the length of the hinge rod 3 is fixed and the hinge rods 3 are distributed in a V-shape, when the threaded sleeve 7 drives the moving plate 10 and one end of the hinge rod 3 to move upward, the other end of the hinge rod 3 will drive the clamping plates 4 to move closer to each other. On the contrary, when the threaded sleeve 7 drives the moving plate 10 and one end of the hinge rod 3 to move downward, the other end of the hinge rod 3 will drive the clamping plates 4 to move away from each other. The other end of the hinge rod 3 is hinged to the bottom end of the clamping plate 4. The clamping plate 4 passes through and is slidably connected to the upper surface of the connecting seat 5. A notch is formed in the connecting seat 5, allowing the clamping plate 4 to slide along the notch of the connecting seat 5. The outer wall of the threaded sleeve 7 is threadedly connected to the middle part of the moving plate 10. The positioning mechanism includes a plug 9. The plug 9 passes through and is slidably connected to the inner wall of the threaded sleeve 7. The surface of the threaded sleeve 7 is bolt-shaped and has the same thread pattern as the middle part of the moving plate 10. By rotating the threaded sleeve 7, the moving plate 10 can be moved vertically. The inner side wall of the plug 9 is elastically connected to the threaded sleeve 7 through a return spring 8. The inner side wall of the plug 9 is fixedly connected to one end of the return spring 8. When the plug 9 moves outward, the return spring 8 will be stretched. During reset, the elastic force of the return spring 8 is used to drive the plug 9 to reset. The other end of the return spring 8 is fixedly connected to the outer wall of the threaded sleeve 7. The plug 9 is inserted into the outer wall of the fixed tube 6. The outer wall of the fixed tube 6 is annularly open, which can block the plug 9 and allow the plug 9 to slide along the annular opening.

[0034] Working principle: When it is necessary to fix the experimental firearm, first place the firearm on the connecting seat 5. By pulling out the plug 9 outward and stretching the return spring 8, the plug 9 is separated from the annular opening of the fixed tube 6. Then, move the threaded sleeve 7 upward to drive the moving plate 10 upward, so that the moving plate 10 drives one end of the hinge rod 3 upward, and the other end of the hinge rod 3 drives the clamping plates 4 to move closer to and contact the experimental firearm for fixation. When further precise fixation of the firearm is required, simply rotate the threaded sleeve 7 clockwise in a circular motion, driving the plug 9 and the return spring 8 to rotate. The moving plate 10 on the threaded sleeve 7 continues to move upward, driving the hinge rod 3 to continue moving upward, and the hinge rod 3 drives the clamping plates 4 to continuously fix the experimental firearm, ensuring that the stability after fixation will not cause the muzzle angle to shift.

[0035] Before the experiment with the experimental firearm, the laser rangefinder 16 can be turned on to measure the shooting distance to avoid errors. After the experiment, when the laser rangefinder 16 needs to be disassembled, assembled and debugged, only move the wedge block 14 to the right and compress the positioning spring 13, so that the wedge block 14 no longer blocks the removal of the mounting block 15 from the connecting block 12. Then, remove the laser rangefinder 16 with the mounting block 15 from the inner wall of the connecting block 12. After removal, release the wedge block 14, and use the reverse elastic force of the positioning spring 13 to drive the wedge block 14 to reset to the left. When the laser rangefinder 16 needs to be installed, just align the mounting block 15 with the connecting block 12 and insert it, and use the outer wall of the mounting block 15 to squeeze the inclined surface of the wedge block 14, so that the wedge block 14 moves to the right and compresses the positioning spring 13. When the mounting block 15 is no longer in contact with the wedge block 14, use the reverse elastic force of the positioning spring 13 to drive the wedge block 14 to pop out and reset, and use the wedge block 14 to block the mounting block 15 in the connecting block 12.

[0036] When it is necessary to release the fixation of the firearm, follow the steps described in the first paragraph above. Rotate the threaded sleeve 7 counterclockwise to return the moving plate 10 to its initial position. Then, release the limit of the threaded sleeve 7 on the fixed tube 6. Subsequently, move the threaded sleeve 7 downward, driving the moving plate 10 and the hinge rod 3 downward, so that the hinge rod 3 drives the clamping plate 4 away from the firearm.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
