Description

Technical Field

[0001] This utility model belongs to the field of ammunition storage container technology, and specifically relates to a propellant sample storage box. Background Technology

[0002] Propellant is primarily used by technical support institutions and training facilities, therefore, propellant samples are typically stored in sample boxes to meet the requirements for propellant sampling and transportation. Currently, propellant sample boxes are usually stacked in wooden crates for transport. Because the sample boxes vary in size, careful placement within the crates is crucial. Improper placement can lead to collisions between boxes during transport, causing static electricity buildup and posing a safety hazard. Furthermore, wooden crates are heavy and inconvenient to handle, resulting in timber waste, forest ecosystem damage, and high transportation costs. Utility Model Content

[0003] To address the above problems, this invention provides a propellant sample storage box.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A propellant sample storage box includes a box body and a box lid. The box body has multiple storage cavities for accommodating propellant sample boxes. The box lid and the box body are movably connected and can be opened and closed, and the box lid and the box body are sealed together. The storage cavities are provided with tensioning structures for fixing propellant sample boxes of different sizes. The multiple storage cavities in the box body are filled with cushioning material, and the top and bottom of each storage cavity are provided with cushioning pads. The box body and the box lid are made of antistatic material.

[0006] Furthermore, the tensioning structure includes multiple clamping plates and a buffer spring. The buffer spring is disposed on the outside of the clamping plates and is used to fix the propellant sample box between the clamping plates. The storage cavity is a circular cavity that matches the shape of the propellant sample box, and the buffer spring is disposed between the inner wall of the storage cavity and the clamping plates.

[0007] Furthermore, the buffer spring is multi-segmented and radially arranged between the inner wall of the storage cavity and the clamping plate, with one end of the buffer spring connected to the clamping plate and the other end connected to the inner wall of the storage cavity.

[0008] Furthermore, the buffer spring is ring-shaped and fitted onto the outside of the clamping plate. The buffer spring is multi-segmented, and two adjacent buffer spring segments are connected by positioning blocks. The outer wall of the clamping plate is provided with positioning grooves that match the positioning blocks. The inner wall of the storage cavity is filled with buffer material between itself and the clamping plate.

[0009] Furthermore, the positioning block is spherical or polygonal.

[0010] Furthermore, one side of the open end of the box is rotatably connected to the box lid, and the other side of the open end of the box is connected to the box lid by a latch; the latch is connected to the box by a lead seal.

[0011] Furthermore, the four side walls of the box body are inclined inward and downward, the bottom four corners of the box body are provided with limiting protrusions, and the top four corners of the box cover are provided with limiting eaves. The limiting protrusions can be placed inside the limiting eaves.

[0012] Furthermore, the box body is symmetrically provided with handles on both sides, and the top of the box lid is provided with a carrying handle.

[0013] Furthermore, the buffer between the multiple storage chambers inside the box is foam, the buffer pad is made of rubber with antistatic function, and the top buffer pad of the storage chamber is located inside the box cover.

[0014] Furthermore, the propellant sample box is made of conductive metal or antistatic plastic, and the box body and lid are made of modified engineering plastic with antistatic function.

[0015] The technological advancements achieved by this invention compared to existing technologies are as follows:

[0016] This invention features multiple storage cavities with internal tensioning structures within a housing. These tensioning structures securely fix propellant sample boxes of different sizes within the storage cavities. After the sample boxes are placed in the housing, the lid is sealed to the housing via latches, achieving a sealed and fixed position for the propellant sample boxes. During transport, buffers are used between adjacent storage cavities to cushion the movement of the propellant sample boxes. Buffer pads at the top and bottom of the propellant sample boxes further restrict their axial movement. These buffers and pads confine the propellant sample boxes within the storage cavities, preventing collisions. The housing and lid, made of antistatic materials, also prevent the accumulation and discharge of static electricity, effectively eliminating static charge. Furthermore, using antistatic materials instead of wood reduces wood consumption, contributing to forest ecosystem protection and lowering transportation costs. Attached Figure Description

[0027] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, a propellant sample storage box includes a box body 1 and a box cover 2. The box body 1 has multiple storage cavities 3 for accommodating propellant sample boxes. The box cover 2 is movably connected to the box body 1 and is sealed to the box body 1. The storage cavities 3 are equipped with tensioning structures to fix propellant sample boxes of different sizes. The multiple storage cavities 3 in the box body 1 are filled with cushioning material, and the top and bottom of each storage cavity 3 are equipped with cushioning pads 4. The cushioning material and cushioning pads can confine the propellant sample boxes within the storage cavities and prevent them from colliding with each other. The box body 1 and the box cover 2 are made of antistatic material, which can prevent the accumulation and discharge of static electricity, which is beneficial to the protection of the forest ecological environment and reduces transportation costs.

[0029] As a preferred structure, such as Figure 2 or Figure 4As shown, the tensioning structure includes multiple clamping plates 5 and a buffer spring 6. The buffer spring 6 is disposed on the outside of the clamping plates 5 and is used to fix the propellant sample box between the clamping plates 5. The storage cavity 3 is a circular cavity that matches the shape of the propellant sample box. The buffer spring 6 is disposed between the inner wall of the storage cavity 3 and the clamping plates 5. A groove matching the clamping plates is machined at the bottom of the storage cavity; and a guide slope 15, wider at the top and narrower at the bottom, is provided at the upper entrance of the clamping plates to facilitate quick insertion of the propellant sample box into the inner hole enclosed by the clamping plates. The buffer spring allows adjustment of the diameter of the inner hole enclosed by the clamping plates to accommodate sample boxes of different diameters, allowing propellant samples of different specifications to be placed in different sample boxes according to actual needs.

[0030] In one specific embodiment of this utility model, such as Figure 2 , 3 As shown, the buffer spring 6 is multi-segmented and radially arranged between the inner wall of the storage cavity 3 and the clamping plate 5. One end of the buffer spring 6 is connected to the clamping plate 5, and the other end is connected to the inner wall of the storage cavity 3. Simultaneously, buffer material 8 is filled between the inner wall of the storage cavity 3 and the clamping plate 5. When placing propellant sample boxes of different sizes, the buffer springs can adjust the radius of the inner hole enclosed by the clamping plate, while the elastic force of the buffer springs firmly fixes the propellant sample boxes in the clamping plate. The buffer material is selected from sponge or shredded paper, further flexibly fixing the clamping plate radially.

[0031] In another specific embodiment of this utility model, such as Figure 4 , 5 As shown, the buffer spring 6 is annularly fitted onto the outside of the clamping plate 5. The buffer spring 6 consists of multiple segments, with adjacent segments connected by a positioning block 7. The outer wall of the clamping plate 5 has a positioning groove that matches the positioning block 7. The space between the inner wall of the storage cavity 3 and the clamping plate 5 is filled with buffer material 8. When propellant sample boxes of different specifications are placed into the clamping plate, the inner radius of the clamping plate is adjusted using the buffer springs. The relative position of the positioning block and the clamping plate is fixed by the cooperation of the positioning block and the positioning groove, preventing the buffer spring from shifting vertically during the placement and transport of the propellant sample box. The buffer material is made of sponge or shredded paper, which can limit the clamping plate around its perimeter, confining it as much as possible to the center of the storage cavity. The above structure has a self-centering function, and this embodiment is preferred.

[0032] In specific manufacturing, the positioning block 7 is spherical or polygonal prism. Figure 5 The positioning block shown in the embodiment is spherical.

[0033] Further optimize the above solution, such as Figure 6As shown, one side of the open end of the box 1 is rotatably connected to the box lid 2, and the other side is connected to the box lid 2 via a latch 9. The latch 9 is connected to the box 1 via a lead seal 10. The latch 9 can be a commercially available duckbill spring hook-and-loop fastener, with an elongated hole at the end of the latch plate. A lock lug with a round hole is installed on the box body, allowing the lock lug to pass through the elongated hole in the latch plate and the lead seal strip to pass through the round hole in the lock lug, thus locking the box when closed. This structure allows the propellant sample box to be secured in place within the box using the latch and lead seal, preventing accidental opening during transport and ensuring safety and reliability.

[0034] To facilitate stacking of storage boxes, such as Figure 6 As shown, the four side walls of the box body 1 are inclined inward and downward. The bottom four corners of the box body 1 are provided with limiting protrusions 11, and the top four corners of the box cover 2 are provided with limiting eaves 12. The limiting protrusions 11 can be placed inside the limiting eaves 12. The cooperation of the limiting protrusions and limiting eaves ensures that the storage boxes stacked vertically maintain their relative positions, preventing the upper storage box from falling due to bumps.

[0035] To further optimize the above structure, handles 13 are symmetrically provided on both sides of the box body 1, and a flexible handle 14 is provided on the top of the box lid 2. The handles make it easier for two people to lift the storage box, and the lifting mechanism makes it easier for a single person to carry the storage box, making it more convenient and faster to move the storage box.

[0036] In specific manufacturing, the buffer between the multiple storage cavities inside the box 1 is polyurethane foam, the buffer pad is made of rubber with antistatic function, the top buffer pad of the storage cavity 3 is set inside the box cover 2 and designed as a frustum-shaped cone that matches the upper entrance of the clamping plate. The upper and lower buffer pads can be used to limit the upper and lower ends of the propellant sample box.

[0037] Meanwhile, the propellant sample box is made of conductive metal or antistatic plastic, and the box body 1 and box lid 2 are made of modified engineering plastic with antistatic function, which can be manufactured using injection molding. Using the above materials to make the propellant sample box and storage box can promptly discharge static electricity, preventing its accumulation and discharge. Furthermore, using antistatic materials instead of wood to make the storage box helps protect the forest ecosystem and reduces transportation costs. It also possesses properties such as moisture resistance, protection against drops, rust, mold, and foreign object intrusion.

[0038] The container is made of military green, with dimensions ≤80cm×40cm×40cm, a thickness ≤1cm, and a weight ≤10Kg (net weight). It features anti-static and drop-proof functions and includes an internal shock-absorbing storage chamber. The storage container can be stacked for transport and is suitable for various carrying modes, including single-person carrying and two-person lifting.

[0039] The propellant sample box has a capacity of ≥100g and is marked to distinguish different sizes, suitable for various propellant types. Furthermore, the specific dimensions of the propellant sample box and its casing can be customized to meet specific needs.

[0040] The aforementioned storage box and propellant sample box have good environmental adaptability, with an operating temperature range of -20℃ to 55℃ and a storage temperature range of -30℃ to 60℃.

[0041] In summary, the storage box provided by this utility model has the following functions:

[0042] 1. Electrostatic protection function: It can provide anti-static protection for the propellant.

[0043] 2. Propellant sample box fixing function: A groove is provided at the bottom of the storage chamber to ensure that the propellant sample box is fixed in the groove. The upper and lower buffer pads and the surrounding buffer material ensure that the propellant sample box does not shake or move. At the same time, the storage chamber is arranged according to a certain rule to facilitate counting.

[0044] 3. Safe storage function: It can withstand vibration and drop impact, and is locked with lead seal.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 make equivalent substitutions for some of the technical features.
