This technology uses a sponge mold and a square cardboard box for packaging, which is prone to uneven stress during packaging and transportation and is easily broken due to external impact and shaking. In addition, the use of a large square cardboard box results in high material costs. Summary of the Invention

[0027] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Example 1: Refer to Figures 1 to 6 A quartz boat-type product transportation and fixing structure includes an outer shell 1 and an inner shell 2. A plurality of clamping pads 3 are provided between the inner shell 2 and the outer shell 1. The clamping pads 3 are in close contact with the outer surface of the inner shell 2 and the inner surface of the outer shell 1, and a cavity 31 is formed between adjacent clamping pads 3. The inner shell 2 is provided with a top plate positioning sleeve 4 and a flange positioning sleeve 5 for fixing the product 6. The flange positioning sleeve 5 is located at one end of the inner shell 2, and two top plate positioning sleeves 4 are respectively located at the other end of the inner shell 2 and the middle position of the inner shell 2. Both the flange positioning sleeve 5 and the top plate positioning sleeve 4 are splicable structures.

[0029] Quartz boats, as critical load-bearing devices in semiconductor manufacturing, photovoltaic cell production, and various high-end heat treatment processes, are typically made of high-purity quartz glass. Quartz glass possesses extremely high thermal stability, chemical inertness, and excellent optical properties, but it is also known for its brittleness and weak resistance to mechanical impact. During transportation from the manufacturer to the customer, or during movement within cleanrooms, quartz boats face multiple risks including vibration, collisions, compression, and temperature and humidity variations. Even minor bumps or stress concentrations can cause microcracks on the surface or even complete breakage, resulting in significant economic losses and potentially disrupting continuous production processes. Therefore, developing an efficient, reliable transportation and securing structure that can adapt to the unique structure and fragile characteristics of quartz boats is of paramount importance for ensuring supply chain security, reducing loss costs, and improving operational efficiency.

[0030] This structure employs a layered protection strategy of "rigid exterior, flexible interior, and intermediate isolation." The outer shell 1, as the outermost barrier, primarily functions to withstand and disperse the main impacts and stacking pressures from the external transportation environment. It is typically made of high-strength, lightweight materials such as engineering plastics, aluminum alloys, or plastic-coated metal sheets to ensure structural robustness and controllable overall weight. The outer shell 1 has a square structure. This design choice offers significant practical advantages: square containers are extremely efficient in warehousing, stacking, and utilizing standard freight space (such as containers and pallets), maximizing space utilization and reducing unit transportation costs. Simultaneously, the flat sides of the square shell facilitate the affixing of labels, barcodes, and operating instructions, and also make it easier to design opening and closing mechanisms such as hinges and latches.

[0031] Echoing the square outer shell 1 is the cylindrical inner shell 2. The inner shell 2 is a cylindrical structure. This design is ingenious. From a mechanical perspective, a cylindrical structure, without defects, can evenly distribute the radial pressure applied externally, avoiding the stress concentration problem that easily occurs at the corners of a square structure. From a manufacturing perspective, the processing of the cylindrical inner shell 2 (e.g., using high-density polyethylene (HDPE) or similar plastics through rotational molding or injection molding) is likely simpler, and compared to a square tube inner shell of similar size, a cylindrical shape generally saves more material. More importantly, the cylindrical inner cavity provides the quartz boat product 6 with a continuous, edge-free surrounding space, further reducing the risk of the product being scratched by the inner wall during axial movement or rotation.

[0032] However, direct contact between the rigid outer shell 1 and the rigid inner shell 2 is not optimal, as vibration and impact are transmitted directly through the rigid connection. Therefore, this structure introduces a crucial buffer medium—a pad 3—between the two. Multiple pads 3 are regularly distributed along the axial and circumferential directions of the inner shell 2, tightly fitting between the outer surface of the inner shell 2 and the inner surface of the outer shell 1, thus "suspending" or "softly fixing" the inner shell 2 within the outer shell 1. The cavity 31 formed between adjacent pads 3 serves multiple functions: firstly, it allows the pads 3 sufficient deformation space under compression to fully absorb and dissipate impact energy; secondly, the cavity 31 forms an airflow channel, helping to balance internal and external pressures during temperature and humidity changes and preventing condensation; and thirdly, it reduces the overall structural weight. The material selection for the pads 3 is crucial, typically employing elastomers with high resilience, high damping, and excellent resistance to compression set, such as polyurethane foam, EPE (expandable polyethylene), or custom-formulated rubber, or even a sponge-like structure, to achieve optimal cushioning and shock absorption.

[0033] The core task of the transport fixing structure is to precisely and securely constrain the quartz boat product 6 itself. The quartz boat typically consists of multiple parallel grooved bars 61, top plates 62 located at both ends, and flanges 63 that may be positioned at one end or a specific location. These components vary in shape and stress characteristics, requiring tailored fixing solutions. This structure innovatively incorporates specialized positioning kits within the inner shell 2: top plate positioning sleeves 4 and flange positioning sleeves 5.

[0034] The top plate positioning sleeve 4 is responsible for securing the top plate 62 of product 6 and the end of the groove bar 61 connected to the top plate. Two top plate positioning sleeves 4 are respectively located at the other end of the inner shell 2 and the middle position of the inner shell 2. This arrangement cleverly achieves "two-point" or "multi-point" support for the long quartz boat (combined with the flange positioning sleeve, it forms at least three-point positioning), effectively preventing the product from bending or twisting during transportation due to its own weight or inertia. The top plate positioning sleeve 4 in the middle position is particularly crucial for ensuring the stability of the extra-long quartz boat.

[0035] The specific design of the top plate positioning sleeve 4 further demonstrates its professionalism. It features a top plate positioning groove 41 and a first positioning groove 42. The top plate positioning groove 41 is an arc-shaped groove used to support and limit the edge of the cylindrical or slightly curved top plate 62, increasing the contact area and reducing pressure. The first positioning groove 42 is used to embed and fix the end of the groove rod 61 extending from the top plate. Particularly noteworthy is that the top plate positioning groove 41 and the first positioning groove 42 form a cross-shaped groove structure. This is a highly efficient and robust design. The "cross shape" means that the positioning groove simultaneously provides constraints perpendicular to the groove rod axis (through the top plate positioning groove's embrace of the top plate) and parallel to the groove rod axis (through the first positioning groove's limiting of the groove rod's end), thus achieving joint fixation of the top plate and groove rod connection on a single component, greatly simplifying the structure and improving positioning accuracy and overall rigidity.

[0036] The flange positioning sleeve 5 is located at one end of the inner shell 2 and is specifically used to secure the end of the quartz boat product with flange 63. Flange 63 is typically a critical interface connecting the quartz boat to external equipment (such as a diffusion furnace door), requiring extremely high dimensional accuracy and integrity. The flange positioning sleeve 5 is correspondingly provided with a flange positioning groove 53 and a second positioning groove 54. The shape of the flange positioning groove 53 matches the outer contour of the flange 63, used to precisely contain and position the flange itself. The second positioning groove 54 is used to secure the end of the groove bar 61 near the flange, ensuring the structural stability of this area.

[0037] For situations where the flange area may bear a large load or require additional cushioning, the structure has been optimized. The flange positioning sleeve 5 also has a flange support pad 51 on the side where the flange positioning groove 53 is located. This support pad can be understood as a reinforced or enlarged part of the positioning sleeve, providing a wider support surface for the flange 63 and preventing excessive local stress. Furthermore, a filler pad 52 can be provided between the flange support pad 51 and the flange 63 of the product 6. The filler pad 52 can be made of a softer, more adaptable cushioning material (such as closed-cell foam or silicone pads) for precise adjustment of clearance, compensation of dimensional tolerances, and providing final soft contact protection for the flange surface, absorbing minor vibrations.

[0038] One of the most practical and user-friendly design features of this structure is its modular design. For the flange positioning sleeve 5, the modular design means that it is divided into two equal parts radially; for the top plate positioning sleeve 4, the modular design means that it is divided into two equal parts axially. This design completely solves the problem of traditional fixing devices requiring the product to be suspended in the air for a long time or undergoing complex fitting operations when installing or removing the quartz boat.

[0039] The specific operating procedure is as follows: When loading the quartz boat, the operator can first place the lower positioning sleeve in the predetermined position of the inner shell 2, and then smoothly place the quartz boat product 6 into the corresponding slot of the lower positioning sleeve. At this point, the product has received initial support. Next, simply close the upper positioning sleeve to complete the complete coverage and locking of the product's top plate, groove bar, or flange. The two parts can be easily connected using pins, clips, Velcro, or straps. The disassembly process is the reverse. This "opening and closing" design greatly reduces the requirements for operating space, simplifies the steps, reduces the risk of product damage due to improper operation, and also facilitates the inspection and maintenance of the fixed structure itself before and after transportation.

[0040] Side pads 11 are provided at both ends of the inner shell 1. These side pads mainly function on the end face of the inner shell 2 or the end of the positioning sleeve, providing axial cushioning to prevent the product and inner shell assembly from axially shifting within the shell during transportation due to sudden braking or starting, thus ensuring longitudinal safety. The clamping pad 3, top plate positioning sleeve 4, flange positioning sleeve 5, side pads 11, filling pads 52, and flange support pads 51 are all made of sponge material. Here, "sponge" is a broad term, likely referring to polyurethane foam or other synthetic foam materials with specific density, pore size, and resilience properties. Foam materials are chosen because they are lightweight, relatively low-cost, easy to process into complex shapes, and have good compression resilience and energy absorption characteristics. At the same time, high-quality cleanroom-compatible foam can effectively prevent dust and static electricity, meeting the stringent cleanliness requirements of the semiconductor industry.

[0041] Example 2: Refer to Figures 1 to 6 A quartz boat-type product transportation and fixing structure includes an outer shell 1 and an inner shell 2. A plurality of clamping pads 3 are provided between the inner shell 2 and the outer shell 1. The clamping pads 3 are in close contact with the outer surface of the inner shell 2 and the inner surface of the outer shell 1, and a cavity 31 is formed between adjacent clamping pads 3. The inner shell 2 is provided with a top plate positioning sleeve 4 and a flange positioning sleeve 5 for fixing the product 6. The flange positioning sleeve 5 is located at one end of the inner shell 2, and two top plate positioning sleeves 4 are respectively located at the other end of the inner shell 2 and the middle position of the inner shell 2. Both the flange positioning sleeve 5 and the top plate positioning sleeve 4 are splicable structures.
