[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0026] like Figure 1 As shown, a sealing ring processing storage device of this application includes a support base 1, an adjustable partition 2, an elastic side guard 3, a fixed column 4, and a movable top cover 5. The various components work together to provide an efficient and safe storage environment for the sealing rings.

[0027] The support base 1 provides a stable bottom support for the entire device, used to bear and secure other components. The support base 1 is typically made of high-strength, pressure-resistant, and corrosion-resistant materials, such as steel or engineering plastics. Its shape is mostly a rectangular planar structure, ensuring stable positioning on the working surface and preventing overall tilting or slippage due to uneven ground or external forces. Mounting holes or slots are provided at the corners of the base for secure connection with the fixed column 4.

[0028] The adjustable partitions 2 are installed parallel to each other above the support base 1, forming a layered structure with the help of multiple fixed columns 4 on both sides of the base. Each partition can move freely up and down and be positioned along the fixed columns 4, allowing the user to flexibly adjust the partition height according to actual needs. Both ends of the partitions are equipped with specially designed sliding groove structures 21, which fit into tracks formed on the columns, thus achieving smooth sliding and stable placement of the partitions. Figure 4As shown, to avoid wear and damage to the sealing ring, the surface of the partition is covered with a soft and elastic cushioning material layer 22. In addition, a slightly concave curved surface 23 is designed in the center of the partition. This design not only increases the friction between the sealing ring and the partition to prevent it from sliding off, but also allows the depth and width of the concave shape to be adjusted according to different sizes of sealing rings to accommodate various product specifications.

[0029] To protect the internal storage space from external influences, flexible side guards 3 are installed between the adjacent fixed columns 4 on both sides of the support base 1. These flexible side guards 3 are made of flexible materials, such as silicone or rubber, which effectively absorb vibrations and prevent external dust particles and other impurities from entering. The upper part of the side guards has an opening design, allowing users to easily insert or remove the sealing ring while ensuring convenience and safety during operation.

[0030] Four fixed columns 4, providing reinforcement and support, are evenly distributed around the perimeter of the support base 1. Each fixed column 4 is slightly higher than the adjustable partition 2, and has a guide hole at the top for opening or closing with the movable top cover 5. The columns are made of materials with good mechanical properties and stability to maintain their structural strength over the long term. The fixed columns 4 are securely connected to the base using screws, welding, or special connectors.

[0031] The movable top cover 5 is designed with one side fixed and the other hinged, allowing it to be flipped up for accessing and retrieving items. This side-flipping design ensures good sealing even when the device is closed, eliminating the risk of foreign objects falling and contaminating the sealing ring. It also facilitates quick opening and closing for the user, greatly simplifying daily maintenance and the handling of the sealing rings while ensuring protective functionality.

[0032] In this application, by precisely adjusting the spacing between each adjustable partition 2, a customized accommodating space can be provided for each specific specification of sealing ring, minimizing the possibility of contact between products; at the same time, the concave curved surface 23 in the middle enhances the gripping ability of a single object, and is supplemented by elastic buffer pads to prevent possible micro-damage; the elastic protective barrier added to the side also adds further safety protection to the entire internal environment, together forming a professional place suitable for long-term static storage of sealing rings.

[0033] In one embodiment, the height adjustment range of the adjustable partition 2 of the sealing ring processing storage device of this application is set from 10 mm to 30 mm. This design aims to accommodate sealing rings of different specifications, ensuring that each sealing ring can obtain the optimal storage condition in its corresponding partition layer, avoiding product damage caused by shaking. Specifically, by setting this height adjustment range, the storage device can maximize the utilization of limited space and provide a stable and flexible storage solution. By adjusting the spacing of each partition, the user can select the height most suitable for a certain type of sealing ring according to actual needs, thereby making the entire system more compatible and practical.

[0034] From a technical perspective, in this design, multiple fixed columns 4 are fixed on both sides of the support base 1. Each column is equipped with a precision-machined sliding mechanism. These grooves allow the partition to slide smoothly up and down along the column and be fixed in a designated position. For example, when the partition position needs to be adjusted, the user only needs to slightly lift the partition and manually push it to complete the new positioning. Then, the pre-installed fasteners are used to lock the partition at the desired height, ensuring the stability and reliability of the overall structure. At the same time, the design of the grooves and fasteners fully considers ease of use, making the height adjustment process both efficient and accurate.

[0035] In one embodiment, such as Figure 3 and Figure 4 As shown, the adjustable partition 2 of the sealing ring processing storage device of this application features a unique sliding groove structure 21. This structure has a limiting hole 25 on each sliding groove, through which a positioning rod 24 is inserted to lock the position of the partition after adjustment. This design ensures the stability of the partition after adjustment, improving the operational convenience and structural reliability of the entire storage device. The position of the limiting hole 25 strictly corresponds to the verticality and straightness requirements of the sliding groove to ensure that the positioning rod 24 can accurately enter the limiting hole 25 during installation.

[0036] The design of the limiting hole 25 and the sliding groove fully considers scenarios where users need to frequently adjust the height of the partitions. For example, in practical applications, users can flexibly adjust the distance between each layer of partitions according to the different specifications and quantities of sealing rings to be stored. After adjustment, the position of the partition can be quickly locked by inserting the positioning rod 24 into the limiting hole 25. This mechanism is not only simple and effective, but also prevents accidental displacement, thus ensuring the safety of the sealing rings placed inside. In addition, the combination of the positioning rod 24 and the limiting hole 25 facilitates disassembly and assembly, allowing for easy operation during daily use, maintenance, and equipment cleaning, thereby improving work efficiency.

[0037] In one embodiment, the buffer material layer 22 of the sealing ring processing storage device of this application is made of an antistatic, wear-resistant soft silicone material. This buffer material layer 22 is disposed on the surface of the adjustable partition 2 to prevent the sealing ring from contacting hard surfaces, reducing damage to the sealing ring during placement and removal. This material not only possesses excellent shock absorption performance to prevent damage caused by minor deformations, but also prevents dust from adhering to the sealing ring due to electrostatic forces through its antistatic properties, thereby achieving a good dustproof effect.

[0038] Specifically, the cushioning material layer 22 covers the entire upper surface of the adjustable partition 2, ensuring effective protection for the sealing ring regardless of where it is placed. This layer adheres tightly to the partition surface and does not impede the partition's ability to slide along the fixed column 4, thus maintaining flexibility during the partition's up-and-down adjustment. Furthermore, the cushioning material layer 22, in conjunction with the concave curved surface 23, better conforms to the shape of the sealing ring when it is placed in the center of the partition, increasing friction and preventing wobbling.

[0039] In one embodiment, such as Figure 4 As shown, the bottom of the concave curved surface 23 of the sealing ring processing storage device of this application is provided with a small drainage hole 26. This structure ensures that even trace amounts of moisture can be drained in a timely manner and prevents it from accumulating in the concave curved surface 23, thereby keeping the sealing ring storage environment dry. The drainage hole 26 is connected to a guide cavity 27 located below it. The guide cavity 27 serves as a transition area to guide water flow away from the storage area. A collection tank 28 is also specially provided on one side of it, which is used to collect all the water discharged through the guide cavity 27, realizing centralized management of water resources.

[0040] The small drain hole 26 is specifically installed at the lowest point of the concave curved surface 23. This layout ensures that all leaked or condensed water can flow in smoothly and be drained away. The guide cavity 27 is directly connected to the bottom opening of the drain hole 26, ensuring that liquid water can flow in smoothly and move along a specific channel. The connection between the guide cavity 27 and the collection tank 28 is seamless, ensuring that there is no residual water. Both the guide cavity 27 and the collection tank 28 are made of corrosion-resistant and impermeable materials to ensure long-term stable working performance.

[0041] For example, in practical implementation, when the ambient humidity is high or external factors cause moisture to intrude, this water vapor will condense into water droplets on the concave curved surface 23 once it cools or accumulates to a certain extent. Through the small drainage hole 26 located at the lowest point of the curved surface, the water droplets will quickly collect and fall into the guide cavity 27, and then be introduced into the collection tank 28 on the side for storage. This process does not require any external power unit assistance; it can achieve the ideal moisture-proof and dehumidification effect through purely physical operation.

[0042] In one embodiment, see specific reference. Figure 2 The elastic side guard 3 of the storage device for processing sealing rings disclosed in this application is made of stretchable rubber material. This material not only has good elasticity and resilience, but can also adapt to shape changes that may occur during the storage of sealing rings of different sizes, ensuring that the side guard will not be damaged or deformed when items are placed in or removed. To improve the internal safety performance of the storage device, an anti-collision foam pad 31 is installed inside the elastic side guard 3. This anti-collision foam pad 31 is tightly attached to the inner surface of the elastic side guard 3, which can further mitigate and absorb the impact force generated by collisions, prevent the sealing ring from directly contacting other hard parts, and thus prevent damage to the sealing ring that may be caused during operation. At the same time, this design effectively reduces friction between internal sealing rings, improves storage stability, and helps to enhance the overall sealing of the device.

[0043] Specifically, the flexible side guards 3 in this device are positioned between two adjacent fixed columns 4, forming a continuous protective barrier that defines and protects the storage space. The flexible side guards 3 extend upwards from the support base 1 to near the movable top cover 5, completely covering the side boundaries of the storage space, thus effectively dividing the upper and lower spaces of each layer. Made of stretchable rubber, the side guards can flexibly accommodate different height adjustments of the partitions. During installation, the anti-collision foam pads 31 are first firmly adhered to the inner surface of the side guards, and then installed together in their respective positions, ultimately ensuring the integrity of the entire storage system. This not only guarantees the safety and stability of the sealed storage but also improves ease of use and efficiency.

[0044] In one embodiment, such as Figure 2 As described above, the fixed column 4 of the sealing ring processing storage device of this application has a built-in guide rail 41 to ensure that the adjustable partition 2 can move up and down more accurately along the guide rail 41. This guide structure prevents the partition from shifting or tilting laterally when adjusting its height, ensuring the verticality and uniformity between multiple partitions. The guide rail 41 is provided with several through holes 42 that match the specifications of the limiting holes 25. When it is necessary to position a certain partition, the positioning rod 24 is inserted into the corresponding through hole 42 and the corresponding limiting hole 25 to fix the specific position.

[0045] Specifically, the fixed column 4 is internally equipped with guide rails 41, which extend upwards from the support base 1 to below the movable top cover 5 and are distributed along the entire fixed column 4. This rail structure allows the sliding grooves installed on both sides of the adjustable partition 2 to engage with it, thereby providing stable and smooth height adjustment performance. Meanwhile, a series of through holes 42 of different heights are arrayed on the guide rails 41 in each fixed column 4. These through holes 42 correspond to the limiting holes 25 on the partition. The operator can select the appropriate height according to actual needs and then insert a slender positioning rod 24 through the hole at the connection point to lock it in place. For example, when a specific layer is desired to be at a certain height, simply adjust the partition to that height and insert the positioning rod 24 to achieve precise fixing.

[0046] In one embodiment, shock-absorbing rubber blocks 11 are embedded on the inner sides of the four corners of the support base 1 of the sealing ring processing storage device of this application. This design ensures that when the device is placed on any ground or other platform, it can effectively absorb minor vibrations, thereby maintaining the stability of the sealing rings stored in the device and preventing them from being affected by the external environment. These shock-absorbing rubber blocks 11 are precisely placed at the inner corners of the support base 1, utilizing the elasticity and damping properties of the rubber material to provide a good shock absorption effect.

[0047] Specifically, the shock-absorbing rubber block 11 is integrated with the support base 1 through a specific process, providing additional cushioning to the device without affecting the overall structural strength of the base. Installation can be achieved by strong adhesive bonding or by embedding it into the pre-reserved space inside the support base 1 using an interference fit. To ensure long-term durability, the shock-absorbing block is made of high-quality synthetic rubber, which not only possesses excellent elastic recovery and aging resistance but also maintains stable mechanical properties under different temperature conditions. Thus, whether it's a collision during handling or a minor vibration caused by equipment operation within the operating area, this component will absorb it, maintaining a quiet and stable state inside the device.

[0048] Specifically, the shock-absorbing rubber block 11 can be manufactured using a pre-forming process and then installed into the inner corner of a pre-designed support base 1. For example, in practical applications, a rubber material with good compression deformation characteristics can be selected, and the matching size can be customized according to the geometric parameters of the support base 1 to ensure a tight fit and ease of assembly and maintenance. The shock-absorbing block and the base can be firmly connected by adhesive, or the expansion and compression of the rubber block can be used to firmly install it in the predetermined position. This embedded structure does not affect the integrity of the base's appearance and ensures effective shock absorption in various working environments.

[0049] In one embodiment, such as Figure 1 and Figure 2As shown, in this application, two sets of magnetic strips 51 are symmetrically installed on both sides of the bottom end of the movable top cover 5 of a sealing ring processing storage device. These magnetic strips 51 are designed to fit tightly with the magnetic plates 52 inside the fixed column 4 and the elastic side guard 3. The combination of the magnetic strips 51 and the magnetic plates 52 ensures that when the movable top cover 5 is closed, it can be firmly attached to the surface of the fixed column 4 by magnetic adsorption. This connection ensures that the movable top cover 5 can be stably closed, effectively preventing external dust and other contaminants from entering the sealing ring storage area. This design feature also takes into account the convenience and practicality of operation, eliminating the need for complex locking mechanisms or auxiliary tools when opening or closing the top cover, thus improving work efficiency and convenience.

[0050] For example, soft permanent magnet materials with appropriate strength and a certain degree of toughness can be placed on both sides of the bottom of the top cover and firmly bonded to the corresponding positions. Simultaneously, each fixed column 4 used to support the adjustable partition 2 and reinforce the overall structural frame, as well as the elastic side guards 3 surrounding the fixed columns 4 and providing frame support, are pre-installed with thin metal sheets arranged with the same magnetic poles facing outwards as magnetic plates 52. This layout optimizes the repulsive effect of like magnets into an attractive relationship between opposite poles when the top cover is lowered and contacts the support columns, achieving a natural sealing function.

[0051] In actual operation, when this device is in use, the sealing ring can be placed on the cushioning material layer 22 covering the surface of the adjustable partition 2. The operator adjusts the height of the adjustable partition 2 according to the specifications of the sealing ring to ensure appropriate spacing between each partition. The sliding groove structure 21 at both ends of the adjustable partition 2 allows for smooth movement and precise positioning of the partition on the fixed column 4, preventing tilting. Each adjustable partition 2 has a concave curved surface 23 in the center to increase friction when the sealing ring is placed, preventing shaking. Elastic side guards 3 are located between two adjacent fixed columns 4, limiting and protecting the storage space to prevent the sealing ring from colliding or falling off during handling or retrieval. The movable top cover 5 opens upwards and to the side, providing convenience when removing or placing the sealing ring, and also effectively preventing external debris from entering the storage device when closed, ensuring the sealing ring is stored in a safe environment. The support base 1 provides stable bottom support for the entire device and bears the weight of all components.

[0052] The exemplary systems and methods of the present invention have been specifically shown and described with reference to the above embodiments, which are merely examples of the best mode for implementing the systems and methods. Those skilled in the art will understand that various changes can be made to the embodiments of the systems and methods described herein without departing from the spirit and scope of the invention as defined in the appended claims when implementing the systems and / or methods.
