Description

Technical Field

[0001] This utility model relates to the field of gun inspection barrel technology, and in particular to a compact gun inspection barrel with a noise reduction and silencing structure. Background Technology

[0002] A gun inspection chamber is a basic piece of equipment specifically designed for safe gun inspection operations in confined spaces such as indoor shooting ranges, training centers, and armories. Gun inspection is a critical safety procedure before, during, or after the use of firearms, or during maintenance. It aims to confirm that there are no foreign objects in the chamber or unfired ammunition, typically achieved by firing blank cartridges or special inspection cartridges to verify the reliability of the firearm's operation. This operation generates a loud muzzle pop and a high-pressure gas impact. The core function of the gun inspection chamber is to contain this firing, effectively attenuating noise, absorbing energy, and capturing any debris through its internal structure. This ensures the safety of the operator and the surrounding environment, meeting the urgent need for safe firearm management in non-open-air locations.

[0003] Currently, most products, in order to achieve sufficient noise reduction, usually adopt a crude approach of simply increasing the wall thickness and internal cavity volume, resulting in a large overall size and excessive weight. This makes it difficult to deploy and store flexibly in space-constrained locations such as next to gun cabinets, inside tactical vehicles, or mobile duty stations, sacrificing ease of use.

[0004] Therefore, it is necessary to design a compact gun inspection barrel with a noise reduction and silencing structure to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of most current products that crudely increase wall thickness and cavity volume for noise reduction, resulting in large size and heavy weight, making it difficult to deploy flexibly next to gun cabinets, tactical vehicles or mobile duty points, and sacrificing convenience, this utility model provides a compact gun inspection barrel with a sound-absorbing and noise-reducing structure.

[0006] Technical solution: A compact gun inspection container with a noise reduction structure includes an outer bag, a pad, straps, shoulder straps, tensioners, side pockets, a noise reduction cover, and a gun inspection container. A pad is fixedly connected to the front of the outer bag. Straps are symmetrically fixedly connected to one side of the front of the outer bag. Shoulder straps are symmetrically fixedly connected to the other side of the front of the outer bag. Tensioners are connected between each shoulder strap and the corresponding strap. Side pockets are fixedly connected to both sides of the outer bag. A noise reduction cover is slidably placed on the top of the outer bag. The gun inspection container is slidably placed inside the outer bag.

[0007] Optionally, it also includes baffles, gears, racks and push rods. Baffles are rotatably connected to both sides of the upper part of the gun inspection barrel. Gears are fixedly connected to the front of both baffles. Racks are symmetrically slidably connected to the front of the gun inspection barrel. Both racks mesh with corresponding gears. Push rods are fixedly connected to the top of both racks through the top of the gun inspection barrel.

[0008] Optionally, it also includes handles and torsion springs, with handles embedded and rotatably connected to both sides inside the gun barrel, and torsion springs connecting both handles to both sides of the gun barrel.

[0009] Optionally, it also includes a bullet detection plate and a collection frame. The bullet detection plate is fixedly connected to the bottom of the gun detection barrel, and a collection frame is slidably placed on both sides of the bullet detection plate.

[0010] Optionally, the bullet test plate has bevels on both sides.

[0011] Optionally, it also includes dampers and abutment frames. Dampers are symmetrically fixedly connected to both sides of the bottom of the gun barrel, and abutment frames are fixedly connected between the bottom telescopic ends of the four dampers. The abutment frames abut against the inner part of the outer casing.

[0012] The beneficial effects are: 1. This utility model effectively solves the problem of the large size and excessive weight of traditional gun inspection containers due to the pursuit of noise reduction effect by combining a split outer bag, gun inspection container and noise reduction cover. With the help of straps, shoulder straps and tensioners, the operator can wear it as a carrying system. The side pockets are used to store accessories, realizing rapid deployment and flexible transfer next to gun cabinets, inside tactical vehicles or mobile duty points with limited space, significantly optimizing the space utilization and tactical adaptability of the equipment.

[0013] 2. When the gun is being tested, the push rod can be pushed to precisely control the opening and closing of the baffle through gear and rack transmission, ensuring that the passage is unobstructed before the barrel is inserted and can be quickly closed after firing. Together with the noise reduction cover and the gun test barrel body, it forms a multi-layer sound-absorbing barrier, effectively attenuating the energy of the muzzle explosion in various frequency bands.

[0014] 3. This utility model transmits the impact force generated by firing to the damper at the bottom through the gun barrel. The damper undergoes controllable compression deformation under the support of the abutment frame, converting the huge impact kinetic energy into heat energy dissipation, which greatly suppresses the vibration and displacement of the whole machine, ensuring the stability and safety of the operation process, and avoiding the secondary noise caused by structural vibration of traditional equipment.

[0015] 4. This utility model achieves automatic collection of cartridge cases by having them fall onto the shell inspection plate after firing, and automatically slide into the corresponding collection frame using the inclined structure on the front and back sides, thus avoiding the trouble and risk of manual picking.

[0026] Example: A compact gun inspection barrel with a noise reduction and silencing structure, such as... Figures 1-9 As shown, it includes an outer bag 1, a pad 2, straps 3, shoulder straps 4, a tensioner 5, side pockets 6, a noise-reducing cover 7, and a gun inspection container 8. The pad 2 is fixedly connected to the front side of the outer bag 1. The straps 3 are symmetrically fixedly connected to the lower front side of the outer bag 1. The shoulder straps 4 are symmetrically fixedly connected to the upper front side of the outer bag 1. Each shoulder strap 4 is connected to a tensioner 5 between it and the corresponding strap 3. Side pockets 6 are fixedly connected to both sides of the outer bag 1. The noise-reducing cover 7 is slidably placed on the top side of the outer bag 1. The gun inspection container 8 is slidably placed on the inside of the outer bag 1. The gun inspection container 8 is made of PEUD fabric and is covered with a waterproof cover using high-frequency heat sealing technology. The external dimensions are 180×180×250mm, and the weight is ≤2.3kg, which meets the Level 3 requirements of GA423-2015 "Police Bulletproof Shield".

[0027] like Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7As shown, it also includes baffles 9, gears 10, racks 11 and push rods 12. Baffles 9 are rotatably connected to the upper left and right sides of the gun inspection barrel 8. Gears 10 are fixedly connected to the front ends of the two baffles 9. Racks 11 are symmetrically slidably connected to the front left and right sides of the gun inspection barrel 8. The two racks 11 mesh with the corresponding gears 10. Push rods 12 are fixedly connected to the top side of the two racks 11 through the top side of the gun inspection barrel 8.

[0028] like Figure 8 and Figure 9 As shown, it also includes a handle 13, a torsion spring 14, a bullet detection plate 15, and a collection frame 16. The handle 13 is embedded and rotated on both the front and rear sides of the inside of the gun detection barrel 8. Both handles 13 are connected to the left and right sides of the left and right sides of the gun detection barrel 8. The bullet detection plate 15 is fixedly connected to the bottom of the inside of the gun detection barrel 8. The bullet detection plate 15 has inclined surfaces on both the front and rear sides. The collection frame 16 is slidably placed on both the front and rear sides of the bullet detection plate 15.

[0029] It also includes a damper 17 and abutment frame 18. The damper 17 is symmetrically fixedly connected to the front and rear sides of the bottom of the gun barrel 8. The abutment frame 18 is fixedly connected between the bottom telescopic ends of the four dampers 17. The abutment frame 18 abuts and cooperates with the inner bottom side of the outer casing 1.

[0030] When this device is needed, first take the gun inspection barrel 8 out from the inside of the outer packaging 1, and place it stably on the operating table by rotating the unfolded handle 13. At this time, the torsion spring 14 is compressed and deformed. After releasing the handle 13, it rotates back to its original position under the force of the torsion spring 14. Then, remove the noise reduction cover 7 from the outer packaging 1 and completely cover the outside of the gun inspection barrel 8 to form the first layer of sound insulation barrier.

[0031] When a gun inspection is required, the two push rods 12 are pushed down, causing the rack 11 to slide down along the gun inspection barrel 8. The rack 11 drives the gear 10 that meshes with it to rotate, which in turn causes the two baffles 9 to rotate and open inside the gun inspection barrel 8, allowing the gun barrel to be smoothly inserted into the gun inspection barrel 8. The huge sound and shock wave generated when firing are first absorbed by the noise reduction cover 7, and then the sound wave is attenuated by multiple reflections inside the gun inspection barrel 8. At the same time, the recoil generated when firing is transmitted to the damper 17 through the gun inspection barrel 8. The damper 17 is compressed and deformed under the support of the abutment frame 18, converting the impact energy into heat energy and dissipating it, effectively suppressing the overall vibration of the device.

[0032] After firing, the spent cartridge case falls onto the test plate 15 and automatically slides into the corresponding collection box 16 using the inclined surfaces on the front and rear sides of the test plate 15. Then, the push rod 12 is pulled to move upward, and the rack 11 drives the gear 10 to rotate in the opposite direction, causing the two baffles 9 to rotate in the opposite direction and close, resealing the internal space of the test gun barrel 8. After the impact, the damper 17 pushes the abutment frame 18 downward to reset and return to the initial state.

[0033] When cleaning is required, the collection box 16 can be directly removed from the gun inspection barrel 8 to empty the spent cartridges. The maintenance process is simple and quick. After use, slide the gun inspection barrel 8 back into the inside of the outer bag 1, put the noise reduction cover 7 back on the top side of the outer bag 1, then wrap the strap 3 around the operator's waist, and cross the shoulder strap 4 over the shoulders. Adjust the tightness with the tensioner 5 so that the padding 2 on the front side of the outer bag 1 fits snugly against the body, making the outer bag 1 easy to carry. At this time, the side pocket 6 can be used to store small tools or accessories for easy access. Loosen the tensioner 5 to remove the entire outer bag 1.

All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
