Description

Technical Field

[0001] This utility model belongs to the field of artillery level protection technology, specifically relating to a protective sleeve for a high and low level. Background Technology

[0002] Leveling instruments occupy an important position in the field of military equipment. As a key measurement component of many weapons and equipment, their accuracy and stability have a decisive impact on the combat performance of weapons and equipment. Especially in core links such as artillery firing adjustment and vehicle movement attitude monitoring, existing leveling instruments are gradually revealing their limitations when dealing with frequent equipment use scenarios.

[0003] With the high frequency of use of modern military equipment, the mobility of equipment and the intensity of firing missions have greatly increased. During high-speed vehicle maneuvers, the strong bumps and vibrations cause the fixed structure of the elevation level to be subjected to continuous impacts. Its internal components, such as the bubble and screws, cannot withstand such violent shaking and become loose. During artillery firing, the violent vibrations generated by recoil further exacerbate this problem, leading to frequent loss of elevation level components and rendering the elevation level unusable. This significantly affects the accurate measurement function of weapons and equipment, thereby interfering with the normal progress of combat missions. These problems directly lead to a decrease in equipment measurement efficiency, an increase in operational complexity, and an inability to meet the stringent requirements of military equipment for measurement accuracy and stability under high-intensity combat conditions.

[0004] Therefore, the applicant proposes a protective sleeve for high and low level instruments to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, a protective cover for a high and low level includes a nylon cloth 6. An airbag 1 is fixedly connected to one side of the nylon cloth 6, and several flexible pads 2 are fixedly connected to one side of the airbag 1. Magic tape 3 is fixedly connected to both sides of the nylon cloth 6. The airbag 1 is provided with an inflation mechanism 5. The inflation mechanism 5 includes a shell 501. A one-way valve 503 is provided in the inner cavity of the shell 501. A folding tube 502 is fixedly connected to one end of the one-way valve 503, and an air inlet 506 is fixedly connected to one side of the folding tube 502.

[0025] One-way vent valves 7 are fixedly connected to both sides of the outer wall of one side of the airbag 1, and both one-way vent valves 7 are connected to the inner cavity of the airbag 1.

[0026] A through groove 4 is provided on one side of the airbag 1 and one side of the nylon cloth 6. A protective bag 8 is fixedly connected to one side of the nylon cloth 6, and the inner cavity of the two through grooves 4 is connected to the inner cavity of the protective bag 8.

[0027] As can be seen from the above, in actual use, the personnel first place the nylon cloth 6 around the outside of the level instrument body. Since the level instrument itself is irregularly shaped, it is difficult to achieve a completely fitted wrapping effect. In this case, the personnel further place the protective bag 8 around the outer ring of the level instrument, thus forming a preliminary wrapping protection for the entire level instrument, thereby enhancing the stability and shock absorption performance of the overall structure. Subsequently, the airbag 1 is inflated. The personnel open the baffle 507 and pull the air inlet 506 outwards, causing it to shift inside the outer shell 501. At this time, the air inlet 506 is in a connectable state, and the personnel can use a small air pump to establish a connection and inject gas. If an air pump cannot be used in an emergency, oral gas can also be used. Inflation is achieved by blowing air into the airbag 1. As air continuously enters the airbag 1, its volume gradually expands and begins to deform, simultaneously pushing the flexible pad 2 to move synchronously. This causes the flexible pad 2 to fit tightly against the adjacent area of ​​the leveling surface, thereby clamping and fixing key components on the leveling device, such as air bubbles and screws, effectively preventing loosening or detachment of components due to vibration or impact. Throughout the inflation process, the folding tube 502 can unfold or retract as the slide rod 505 moves within the slide groove 504, ensuring smooth airflow. The one-way valve 503 ensures that air can only enter the airbag 1 and will not flow back, improving inflation efficiency and stability. The spring hinge 508 helps to restore the air intake assembly after inflation is complete. The initial position ensures good repositioning and reusability of the device. This structural design effectively solves the technical problem of component loosening and loss in existing high and low levels under frequent use and severe vibration environments. The combined use of airbag 1 and flexible pad 2 achieves dynamic wrapping and buffering protection for key parts of the level, avoiding the shortcomings of traditional rigid protective shells that cannot adapt to complex shapes and irregular vibrations. The protective bag 8 and nylon cloth 6 further enhance the overall physical isolation and environmental protection capabilities of the level, improving its durability and reliability under harsh battlefield conditions. The inflation mechanism 5 includes the outer shell 501, folding tube 502, one-way valve 503, slide groove 504, slide rod 505, air inlet 506, and stop. The coordinated operation of components such as plate 507 and spring hinge 508 not only improves inflation efficiency and ease of operation but also ensures the adaptability and safety of the device in different usage scenarios. Furthermore, the design of the magic tape 3 allows users to flexibly adjust the fixation between the nylon cloth 6 and the protective bag 8 according to actual conditions, further enhancing the overall structural adaptability and sealing. When pressure needs to be released or disassembled, the airbag 1 can be slowly depressurized via the one-way vent valve 7, achieving rapid decompression and recovery, improving safety and convenience of use. In summary, this structure not only significantly improves the stability and service life of the high and low level gauge under high-intensity usage environments but also meets the comprehensive requirements of modern military equipment for measurement accuracy, rapid response, and high-reliability protection.

[0028] Example 2:

[0029] Please see Figures 1-4 As shown, a baffle 507 is rotatably connected to one side of the outer casing 501 via a spring hinge 508.

[0030] Both sides of the outer wall of the folded tube 502 are fixedly connected with slide rods 505, and both sides of the inner wall of the outer shell 501 are provided with slide grooves 504 that are adapted to the slide rods 505.

[0031] The air inlet 506, the folded tube 502 and the one-way valve 503 are interconnected, and the one-way valve 503 is connected to the inner cavity of the airbag 1.

[0032] As can be seen from the above, through the coordinated design of airbag 1 and one-way degassing valve 7, when it is necessary to release the gas inside airbag 1, personnel can manually control one-way degassing valve 7 to slowly release the gas, allowing airbag 1 to gradually return to its initial state. This achieves the effects of facilitating rapid decompression, improving safety and ease of operation. The coordinated design of airbag 1, nylon cloth 6, and through-slots 4 creates a ventilation channel between airbag 1 and nylon cloth 6. Simultaneously, both through-slots 4 are connected to the inner cavity of the protective bag 8, achieving gas flow and pressure balance during inflation or deflation. This enhances the overall breathability of the device, prevents localized pressure anomalies, and improves the stability of the wrapping fit. Through the spring hinge 508 connecting the outer shell 501 and the baffle 507, when the air inlet 506 is not in use, the baffle 507 can automatically close under the action of the spring, providing dust protection for the air inlet 506. The system allows for easy opening when inflation is needed, improving sealing, extending component lifespan, and ensuring the cleanliness of the inflation components. Through the coordinated arrangement of the slide rod 505 and the slide groove 504, when the folded tube 502 extends or retracts with the gas flow, the slide rod 505 slides along the slide groove 504, limiting its movement direction and providing guiding support. This ensures the folded tube 502 maintains a stable trajectory during inflation, improving structural stability, reducing movement deviation, and enhancing the reliability of the inflation process. The connection between the air inlet 506, the folded tube 502, the one-way valve 503, and the airbag 1 allows external gas to sequentially enter the airbag 1 through the air inlet 506, the folded tube 502, and the one-way valve 503. The one-way valve 503 effectively prevents gas backflow, ensuring one-way gas flow, improving inflation efficiency, preventing leakage, and enhancing system sealing.
