Description

Technical Field

[0001] This invention belongs to the field of packaging container technology, specifically relating to a buttonless deformable opening structure. Background Technology

[0002] Packaging containers are used to hold cosmetics, food, or medicine, and existing containers generally include a box and a lid. However, current lid opening mechanisms mostly use external mechanical buttons with springs or snap-on mechanisms. This requires drilling holes in the container surface to install the button, which compromises the seal and makes it susceptible to water and dust ingress. Furthermore, exposed external buttons are prone to accidental activation or opening, causing the contents to spill out and affecting normal use. Therefore, we propose a buttonless deformation-type lid opening structure to solve the problems existing in the prior art, thereby improving its sealing performance and safety against accidental opening. Summary of the Invention

[0003] The purpose of this invention is to provide a buttonless, deformable opening structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A buttonless, deformable opening structure includes a box body, an assembly base, a bottom cover plate, and a top cover plate. The top and bottom of the box body are respectively provided with a top cover latch and a bottom cover latch, which respectively engage with the inner walls of the bottom cover plate and the top cover plate. The side of the box body is provided with a deformable pressing part for opening the top cover plate. The assembly base is fixedly connected to the bottom of the box body's inner cavity. The inner wall of the bottom cover plate is provided with an assembly frame that engages with the assembly base. The inner wall of the assembly base is provided with a locking mechanism to assist in positioning and preventing the assembly frame from detaching. The top cover plate is movably connected to one side of the box body via a sealing hinge. The inner wall of the top cover plate is movably provided with an opening spring for assisting in opening the top cover plate.

[0005] Preferably, the edges of both the bottom cover plate and the top cover plate are provided with inwardly rolled reinforcing folds, and the top cover latch and the bottom cover latch are respectively sealed and latched with the reinforcing folds.

[0006] Preferably, the assembly frame is symmetrically connected to the surface of the inner assembly frame, the inner wall of the bottom cover plate is provided with the inner assembly frame, and the outer side of the inner assembly frame is provided with a sealing gasket that seals with the bottom cover clip.

[0007] Preferably, the locking mechanism includes: a connecting guide rod connected to the inner wall of the mounting base, and a locking positioning block slidably mounted on the surface of the connecting guide rod; wherein, a protective adjustment part is connected to the top of the locking positioning block, a fixing spring is fitted on the surface of the connecting guide rod, and one end of the fixing spring is connected to the side of the locking positioning block.

[0008] Preferably, the top of the mounting base has a limiting groove, and the protective adjustment part is movably connected to the inner wall of the limiting groove.

[0009] Preferably, the bottom of the assembly base is provided with an insertion slot, and the top of the assembly frame is fixedly connected with a positioning pin.

[0010] Preferably, the positioning pin is movably inserted into the interior of the insertion slot, and the inner side of the positioning block is movably engaged with the surface of the positioning pin.

[0011] Preferably, anti-slip limiting parts for assisting the opening of the upper cover are symmetrically installed on both sides of the box body, and the anti-slip limiting parts are located below the deformation pressing part.

[0012] Preferably, the inner wall of the upper cover plate is provided with a fixing groove, and the inner wall of the fixing groove is provided with a positioning post. The opening spring is movably assembled to the inner wall of the fixing groove through the positioning post.

[0013] Preferably, a fixing block is connected to the surface of the inner wall of the box located at the upper cover latch, one end of the opening spring is engaged with the top of the fixing block, and a sealing pressure ring that engages with the upper cover latch is bonded to the inner wall of the upper cover plate.

[0014] Technical effects and advantages of the present invention: The buttonless deformation opening structure proposed in this invention has the following advantages compared with the prior art: This invention utilizes a combination of components including a box body, a deformation-pressing part, an assembly base, a bottom cover, an upper cover, an opening spring, and a locking mechanism. The user simultaneously presses the deformation-pressing parts on both sides of the box body with their fingers. This pressing causes a controllable elastic deformation of the box body's sidewalls. This deformation is transmitted to the upper cover latch area at the top of the box body, creating a slight displacement or gap between the latch and the inner wall of the upper cover, thus releasing the latch on the upper cover. After the upper cover latch is released, the previously compressed opening spring releases its stored energy, and, in conjunction with the top surface of the fixed stop, pushes the upper cover, causing it to automatically spring upwards around the sealing hinge. The user can then fully open the upper cover, enabling one-handed opening. After releasing the deformation-pressing part, the box body's sidewalls recover their original shape due to the material's elasticity. When it is necessary to close the upper cover again, simply press down on the upper cover; the opening spring is recompressed and re-energized, and the upper cover latch engages with the inner wall of the upper cover again, returning to the closed and locked state.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides, for example Figure 1-6 The illustrated buttonless deformable opening structure includes a box body 1, an assembly base 6, a bottom cover plate 14, and an upper cover plate 19. The top and bottom of the box body 1 are respectively provided with an upper cover latch 2 and a bottom cover latch 3, which respectively engage with the inner walls of the bottom cover plate 14 and the upper cover plate 19. The side of the box body 1 is provided with a deformable pressing part 5 for opening the upper cover plate 19. The assembly base 6 is fixedly connected to the bottom of the inner cavity of the box body 1. The inner wall of the bottom cover plate 14 is provided with an assembly frame 17 that engages with the assembly base 6. The inner wall of the assembly base 6 is provided with a locking mechanism to assist in positioning and preventing the assembly frame 17 from detaching. The upper cover plate 19 is movably connected to one side of the box body 1 via a sealing hinge 20. The inner wall of the upper cover plate 19 is movably provided with an opening spring 24 for assisting in opening the upper cover plate 19.

[0019] It is worth noting that through the coordinated arrangement of the box body 1, the deformation pressing part 5, the mounting base 6, the bottom cover plate 14, the top cover plate 19, the opening spring 24, and the locking mechanism, the deformation pressing part 5 is set on both sides of the box body 1. Users do not need to find physical buttons; they only need to press the side wall of the box body 1 to trigger the opening action by utilizing the material deformation. With the assistance of the opening spring 24, the opening action can be smoothly achieved with one hand, making the operation intuitive and effortless. Furthermore, there are no exposed buttons or buckles. The use of a pressing deformation structure combined with the spring opening and closing effectively reduces moving parts and lowers the risk of failure due to dust, liquid intrusion, or mechanical fatigue.

[0020] By adjusting the thickness, material, or structural dimensions of the deformation-pressing part of the side wall of the box body 1, the required pressing force and stroke can be set. Appropriately increasing the deformation trigger threshold can effectively prevent accidental activation caused by slight vibrations or ordinary external forces, while maintaining a light and easy feel during normal use, achieving a balance between "anti-accidental touch" and "easy operation." The deformation-pressing part 5 is located on both sides of the box body 1 and typically requires simultaneous pressing from both sides or at a specific angle to effectively unlock, simulating a "pinch" action. This operating posture is not easily formed spontaneously in a natural holding or storage state, and sudden unilateral external forces such as squeezing from inside a bag cannot meet the unlocking conditions, thus further enhancing the anti-accidental touch capability.

[0021] On the other hand, the deformation pressing part 5 can also be designed on the opening and closing side of the box body 1. The opening spring 24 inside the upper cover plate 19 is located on both sides of the deformation pressing part 5, forming a front and rear deformation opening and closing structure. The surface of the deformation pressing part 5 can be printed to indicate to the user that this is the pressing part. The upper cover card part 2 on the front side of the box body 1 is provided with a rice dot structure that cooperates with the reinforcing folded edge that rolls inward with the upper cover plate 19. The reinforcing folded edge and the rice dot structure are not rolled to the bottom, forming a fishhook-shaped winding structure.

[0022] Box 1 serves as the main structural support, housing internal components and protected objects, providing structural strength and a foundation for spatial layout. The top cover 19 seals the top of box 1 but can be opened for easy access to internal items. The bottom cover 14 seals the bottom of box 1, enabling infrequent disassembly and assembly. The top cover latch 2 engages with the inner wall of the top cover 19 to form a locking mechanism, ensuring the top cover 19 is securely closed and preventing accidental opening. The bottom cover latch 3 engages with the inner wall of the bottom cover 14 to form a locking mechanism, ensuring a stable connection between the bottom cover 14 and box 1.

[0023] Instead of using a separate mechanical button, the deformable pressing part 5 on both sides of the box body 1 is used as the trigger element for opening the lid. This reduces the number of parts, simplifies the mold structure, and lowers the assembly cost. It can also effectively avoid the risk of dust and water entering through the gaps in the button opening. At the same time, combined with the sealing hinge 20, sealing pressure ring 21, sealing gasket 16 and other structures, it ensures good sealing potential. The deformable pressing part 5 area is an integral structure with the box body, so the force transmission is more direct and the tactile feedback is clear.

[0024] Both the bottom cover plate 14 and the top cover plate 19 have inwardly rolled reinforcing folds at their edges. The top cover latch 2 and the bottom cover latch 3 are respectively sealed and latched with the reinforcing folds. The assembly frame 17 is symmetrically connected to the surface of the assembly inner frame 15. The inner wall of the bottom cover plate 14 is provided with the assembly inner frame 15, and the outer side of the assembly inner frame 15 is provided with a sealing gasket 16 that seals with the bottom cover latch 3. Anti-slip limiting parts 4 that assist in opening the top cover plate 19 are symmetrically installed on both sides of the box body 1. The anti-slip limiting parts 4 are located below the deformation pressing parts 5.

[0025] The top cover latch 2 of the box body 1 is fitted with the inner wall of the top cover plate 19, and the bottom cover latch 3 of the box body 1 is fitted with the inner wall of the bottom cover plate 14. The edges of the bottom cover plate 14 and the top cover plate 19 are provided with inwardly rolled reinforcing folds, and these folds are directly sealed and latched with the top cover latch 2 / bottom cover latch 3 of the box body 1. The rolled and reinforced fold structure significantly increases the edge rigidity of the cover plate, resists deformation, and improves the performance under frequent opening and closing. The sealing gasket 16 on the outer side of the inner frame 15 is fitted with the bottom cover latch 3 to achieve a static seal at the bottom. The sealing pressure ring 21 of the top cover plate 19 is fitted with the top cover latch 2 to achieve a dynamic seal at the top.

[0026] Strengthening the folded edge overcomes the shortcomings of traditional flat cover plates, such as weak edge strength, easy bending, and easy warping. The rolled edge structure effectively disperses the external forces of compression and impact on the cover edge, significantly improving the overall structural rigidity and resistance to bending and deformation. This prevents problems such as edge warping, deformation, and cracking during daily handling, squeezing, and impacts. At the same time, the cover's structural dimensions remain stable and do not deform, ensuring a tight seal between the strengthened folded edge and the box body. This avoids problems such as seal failure, loosening of the snaps, and increased gaps caused by cover deformation, maintaining the overall sealing performance and assembly precision of the machine over the long term.

[0027] Specifically, the inner frame 15 is a locking structure that engages with the bottom of the bottom cover clip 3, ensuring that deformation of the top cover clip 2 does not cause excessive interference to the bottom of the box body 1. The sealing gasket 16 is a structure that improves the sealing effect inside the box body 1. The edge of the top cover 19 adopts a rolled-up built-in hinge design, eliminating the need for openings for hinges and achieving a full-circumference seal without openings. This effectively solves the sealing defects caused by traditional hinges with windows. Furthermore, the edge of the top cover 19 adopts an inwardly rolled reinforced folded edge structure, which effectively enhances the rigidity of the box body, prevents the thin material from easily deforming, and limits the deformation position and amplitude, allowing unlocking only in specific areas. Adjusting the depth of the folded edge allows for precise control of the opening force. The material can be made of different hardness materials such as PP, PE, ABS, and soft rubber composites to adjust the deformation and opening force, making it easy for adults to open and less likely for children or accidental opening due to daily vibrations.

[0028] The inner wall of the upper cover plate 19 and the upper cover latch 2 of the box body 1 are engaged with a snap-fit ​​mechanism with zero gap, ensuring no looseness under normal conditions. A micron-level deformation allowance is reserved internally; when the deformation pressing part 5 is squeezed, a slight displacement occurs, allowing the snap-fit ​​to misalign and unlock. The snap-fit ​​mechanism on the surface of the upper cover latch 2 can use arc-shaped, trapezoidal, or oblique tooth snap-fit ​​mechanisms to achieve zero-gap engagement and misalignment unlocking. Both the bottom cover plate 14 and the upper cover plate 19 employ inwardly rolled reinforced folded edges, forming a sealed snap-fit ​​connection with the upper cover latch 2 and bottom cover latch 3 of the box body 1. Combined with the sealing gasket 16 on the outer side of the inner frame 15 and the sealing pressure ring 21 on the inner wall of the upper cover plate 19, this effectively prevents moisture and dust from entering through the seams, improving the protection level of internal components or items.

[0029] The deformation pressing part 5 and its vicinity constitute a dedicated deformation area. The remaining areas of the box body 1 are rigidly supported by the upper cover latch 2, the fixing block 13, and the mounting base 6. Deformation is controllable only near the pressing area. The main body of the box body 1 is not prone to permanent deformation under pressure. After repeated pressing to open the lid, the shell is not prone to irreversible cracking or deformation, thus extending the product's service life. Furthermore, the surface is completely flat, with no protrusions that would be uncomfortable to hold. The upper cover 19 can only be automatically opened by pressing from both sides simultaneously, making operation simple. The bottom cover is self-locking and secure, and will not fall off unexpectedly during daily use, making it convenient to use.

[0030] By eliminating the physical buttons, button openings, and external toggle switches required for traditional lid opening, the entire lid opening and unlocking process is completed using the controllable elastic deformation of the specially designed deformable pressing parts 5 on both sides of the housing 1. This results in a device with no openings, protruding buttons, or switch structures on the overall outer surface, leading to a highly integrated and flat appearance. This effectively avoids common malfunctions of traditional button structures, such as button jamming, button detachment, button wear and failure, and dust and water ingress through openings. Furthermore, the deformable pressing parts 5 are integrally molded into the housing 1, ensuring structural consistency and resistance to pressure fatigue. This allows for repeated pressing and unlocking over extended periods without the problems of loosening, shifting, or malfunctioning of external buttons, significantly improving the overall stability and durability of the lid opening structure. The locking mechanism includes a connecting guide rod 9 connected to the inner wall of the mounting base 6, and a locking positioning block 10 slidably mounted on the surface of the connecting guide rod 9; wherein, the top of the locking positioning block 10 is connected to a protective adjustment part 11, and a fixing spring 12 is fitted on the surface of the connecting guide rod 9, and one end of the fixing spring 12 is connected to the side of the locking positioning block 10.

[0031] Furthermore, the connecting guide rod 9 is a structure that guides and limits the clamping positioning block 10, ensuring the stability of the position of the clamping positioning block 10. The protective adjustment part 11 works with the limiting groove 8 to protect the internal fixing spring 12, and at the same time facilitates the subsequent disassembly of the bottom cover plate 14. The fixing spring 12 acts on the clamping positioning block 10 to clamp and lock the positioning pin 18.

[0032] The connecting guide rod 9 is fixed to the inner wall of the assembly base 6 and is used to install the clamping positioning block 10 and provide sliding guidance for the clamping positioning block 10. The clamping positioning block 10 is slidably installed on the connecting guide rod 9 and has a structure in which the positioning pin 18 is clamped on the inner side to realize the locking and releasing control of the assembly frame 17. The fixing spring 12 is fitted on the connecting guide rod 9 and has one end connected to the clamping positioning block 10 to provide continuous locking force for the clamping positioning block 10 and ensure that the positioning pin 18 will not loosen.

[0033] The top of the mounting base 6 has a limiting groove 8, and the protective adjustment part 11 is movably connected to the inner wall of the limiting groove 8. The bottom of the mounting base 6 has an insertion groove 7, and the top of the mounting frame 17 is fixedly connected to a positioning pin 18. The positioning pin 18 is movably inserted into the inside of the insertion groove 7, and the inner side of the positioning block 10 is movably engaged with the surface of the positioning pin 18.

[0034] The protective adjustment part 11 is connected to the top of the clamping positioning block 10 and moves within the limiting groove 8. It is used for manual unlocking operation, while limiting the sliding stroke and providing a sealing and protective effect for the internal fixed spring 12 structure. The limiting groove 8 is opened at the top of the assembly base 6, and the protective adjustment part 11 moves within it to guide the unlocking action direction and prevent excessive stroke from damaging the spring. The insertion groove 7 is opened at the bottom of the assembly base 6 and forms an initial positioning with the positioning pin 18 for easy blind installation. The positioning pin 18 is fixed to the top of the assembly frame 17 and movably inserted into the insertion groove 7. It cooperates with the clamping positioning block 10 to achieve automatic locking and anti-disengagement.

[0035] An elastic locking mechanism consisting of a connecting guide rod 9, a snap-fit ​​positioning block 10, and a fixing spring 12 is integrated inside the assembly base 6. This mechanism forms a controllable snap-fit / release engagement with the positioning pin 18 on the assembly frame 17. During assembly, the assembly frame 17 is inserted, causing the positioning pin 18 to push open the snap-fit ​​positioning block 10. Once in place, the fixing spring 12 resets and locks, achieving automatic locking. When disassembly is required, the spring force can be overcome by operating the protective adjustment part 11, allowing for repeated disassembly and assembly while preventing accidental loosening. The mechanism is hidden inside the assembly base 6, which does not affect the appearance and can withstand a large pulling force, while ensuring that the external sealing structure is not affected by interference.

[0036] Furthermore, the insertion slot 7 is a structure that assembles the bottom cover plate 14 with the positioning pin 18, facilitating the locking of the positioning block 10 and the positioning pin 18 to ensure the stability of the structure. Through the interaction of the connecting guide rod 9, the positioning block 10, and the fixing spring 12 within the assembly base 6 with the positioning pin 18 on the assembly frame 17, when the assembly frame 17 is inserted into the insertion slot 7, the positioning block 10 automatically locks the positioning pin 18 under the action of the fixing spring 12, forming a mechanical anti-detachment structure. This ensures a long-term stable connection between the bottom cover plate 14 and the box body 1, preventing loosening. The bottom cover plate 14 is inserted and positioned via the assembly frame 17 and the assembly base 6, and is quickly locked in place by the locking mechanism. Installation and removal of the bottom cover plate 14 can be completed without additional screws or tools, which is beneficial for improving production assembly efficiency and subsequent internal maintenance or component replacement.

[0037] The assembly base 6 serves as a fixed base for the bottom of the box 1 and integrates a locking mechanism, a limiting groove 8, and an insertion groove 7. The assembly frame 17 simultaneously undertakes positioning, force transmission, and sealing pressing functions, reducing additional supports or connectors and ensuring internal storage space for the box 1. The limiting groove 8 cooperates with the protective adjustment part 11 to guide the adjustment action and prevent excessive travel from damaging the spring. The initial positioning of the insertion groove 7 and the positioning pin 18 facilitates blind assembly and improves production assembly efficiency.

[0038] The inner wall of the upper cover plate 19 is provided with a fixing groove 22, and the inner wall of the fixing groove 22 is provided with a positioning post 23. The opening spring 24 is movably assembled to the inner wall of the fixing groove 22 through the positioning post 23. The inner wall of the box body 1 is connected to the surface of the upper cover latch 2 with a fixing block 13. One end of the opening spring 24 is engaged with the top of the fixing block 13. The inner wall of the upper cover plate 19 is bonded with a sealing pressure ring 21 that engages with the upper cover latch 2.

[0039] The bottom cover plate 14 is aligned and inserted into the insertion slot 7 of the inner cavity assembly seat 6 of the box body 1 by the inner wall assembly frame 17 and the positioning pin 18, so as to achieve the pre-installation and positioning of the bottom cover plate 14 without the need for screw tightening, simplifying the assembly process and improving the assembly efficiency. The assembly frame 17 is automatically locked to prevent the bottom cover plate 14 from being accidentally loosened and falling off due to vibration or drop.

[0040] When it is necessary to disassemble the bottom cover 14 or maintain and clean the internal structure of the box 1, simply move the protective adjustment part 11 inside the limiting groove 8 to drive the locking positioning block 10 to slide and compress the fixing spring 12, so that the locking positioning block 10 disengages from the locking engagement with the positioning pin 18, quickly releasing the locking state, and the bottom cover 14 can be removed. This design balances locking reliability with ease of disassembly and maintenance; the limiting groove 8 of the assembly base 6 constrains the movement of the protective adjustment part 11, and the insertion groove 7 limits the insertion position of the positioning pin 18, resulting in a high tolerance for assembly misalignment. This reduces the likelihood of misalignment or displacement during assembly, improves the assembly yield, and ensures a secure and stable assembly for daily use.

[0041] Among them, the sealing hinge 20 can adopt an integrated thin-film hinge or a double-point built-in hinge to maintain a sealed position without opening the window. Even if the upper cover plate 19 is subjected to an unexpected upward external force, the elastic force of the opening spring 24 will be resisted by the upper cover latch 2 and the latching structure of the upper cover plate 19; at the same time, the locking mechanism on the side of the bottom cover plate 14 adopts a spring-loaded latching positioning block 10 and a positioning latch 18 to form a self-locking anti-disengagement structure. Under non-active deformation pressing part 5, the upper cover plate 19 cannot spring up on its own, further enhancing the overall locking reliability of the structure.

[0042] A lid-opening spring 24, with one end abutting against a fixed stop, is provided on the inner wall of the upper cover plate 19. Combined with an anti-slip limiting part 4 added below the deformation pressing part 5 on the side of the box body 1, the lid-opening spring 24 automatically springs the upper cover up to a certain angle after the pressing part 5 releases the latch between the upper cover and the reinforcing fold, enabling convenient one-handed opening. The anti-slip limiting part 4 provides a finger stop point during pressing, preventing excessive force or slippage, and also avoiding damage to the structure from excessive pressing stroke. The lid-opening spring 24 only functions at the moment of unlocking. When the upper cover plate 19 is closed, the lid-opening spring 24 is in a compressed, energy-storing state. When the upper cover latch 2 disengages, the lid-opening spring 24 releases energy to spring the upper cover plate 19 to the unlocked state. The concealed assembly of the spring does not occupy the effective internal space of the box body 1, resulting in a compact overall structure. Furthermore, the spring force decays evenly during repeated opening and closing, ensuring consistent opening force without jamming, weak opening, or excessive opening, providing a stable opening and closing feel.

[0043] Anti-accidental touch principle: The deformable pressing part 5 requires the user to actively apply a directional and certain force to trigger the unlocking, and accidental collision or friction on one side cannot cause the box body 1 to deform effectively; even if the upper cover 19 is subjected to an unexpected upward external force, the force of the opening spring 24 is not enough to overcome the damping of the sealing hinge and the resistance of the locking engagement, and it needs to be used in conjunction with the deformable pressing part 5 to open, thereby effectively preventing accidental opening.

[0044] The top cover 19 is movably connected by a sealing hinge 20, and one end of the opening spring 24 cooperates with the fixed stop 13. After the top cover 19 is released by the deformation pressing part 5, the opening spring 24 provides an elastic opening force to automatically open the top cover 19, preventing the top cover 19 from getting stuck. At the same time, the anti-slip limiting part 4 on the side of the box body 1 can increase the friction of the fingers when pressing, improving the stability of operation.

[0045] By optimizing the stress-bearing zoning design of the box body 1 structure, only the two sides of the box body 1 are designated as elastically deformable pressing parts 5, specifically for opening and unlocking deformation. During the pressing and opening process, only the pressing parts 5 undergo controllable micro-elastic deformation, and the main structure of the box body 1 does not generate deformation stress, effectively avoiding the problems of permanent deformation, cracking, and fatigue damage caused by long-term pressing of the box body 1. The remaining rigid support structure ensures the overall structural strength of the machine, with strong resistance to compression and impact, high overall structural stability, and a significantly extended service life.

[0046] The upper cover plate 19 is movably connected to one side of the box body 1 via a sealing hinge 20. When closed, the sealing pressure ring 21 on the inner wall of the upper cover plate 19 and the upper cover latch 2 on the top of the box body 1 form a sealing contact. At the same time, the opening spring 24 installed in the fixing groove 22 on the inner wall of the upper cover plate 19 is compressed, and one end of it abuts against the top of the fixing block 13 on the inner wall of the box body 1, and is in a state of energy storage and ready to be released. The bottom cover plate 14 is inserted into the mounting base 6 at the bottom of the box body 1 via the mounting frame. The positioning pin 18 at the top of the mounting frame 17 is inserted into the bottom of the mounting base 6. The insertion slot 7 is inserted into the box; at the same time, the locking mechanism inside the mounting base 6 is activated. Under the push of the fixed spring 12, the mounting positioning block 10 slides along the connecting guide rod 9 and automatically engages with the surface of the positioning pin 18 to form an anti-disengagement lock, ensuring that the bottom cover plate 14 is firmly connected to the box body 1; the sealing gasket 16 on the outside of the mounting inner frame 15 is tightly fitted with the bottom cover locking part 3 to achieve bottom sealing; under no external force, the deformation pressing parts 5 on both sides of the box body 1 are in a natural state and do not trigger unlocking; the entire structure is in a stable sealed and locked state.

[0047] When opening, the user presses the deformation pressing parts 5 on both sides of the box body 1 with their fingers simultaneously. The pressing causes a controllable elastic deformation of the side wall of the box body 1. This deformation is transmitted to the upper cover locking part 2 area at the top of the box body 1, causing a slight displacement or gap between the upper cover 19 and the inner wall of the upper cover plate 19, thus releasing the locking constraint on the upper cover plate 19. After the upper cover plate 19 is released, the opening spring 24, which was previously in a compressed state, releases its stored energy and, together with the top surface of the fixed stop 13, pushes the upper cover plate 19, causing it to automatically spring upward around the sealing hinge 20. The user can then fully open the upper cover plate 19, achieving one-handed opening operation. After releasing the deformation pressing parts 5, the side wall of the box body 1 returns to its original shape due to the elasticity of the material itself. When it is necessary to close the upper cover plate 19 again, simply press down on the upper cover plate 19, and the opening spring 24 is compressed and stored energy again.
