[0002] This invention relates to the field of storage box technology, and more specifically, to a storage box. Background Technology

[0003] In daily life, people often eat snacks and fruits, so storage boxes are needed to store them. Traditional food storage containers require both hands to turn the lid or considerable force to open and remove the food from the container, which is inconvenient.

[0004] To address the inconvenience of operating storage boxes, existing technology provides a push-button storage box, including a box body and a lid. The lid has a button in the center that presses down and releases to return to its original position. A single press closes the lid, and a second press opens it. While both opening and closing are triggered by pressing, the button typically springs upwards when the user presses it. The user then has to wait for the button to fully rise before grasping it and removing the lid. This pressing-and-grabbing process is time-consuming, inconvenient, and reduces user experience.

Detailed Implementation

[0052] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] Example 1

[0054] As shown in Figures 1 to 7, Embodiment 1 of the present invention provides a storage box. The storage box includes: a box body 1 having a storage cavity 2 and an opening 3 communicating with the storage cavity 2; a box lid 4 covering the opening 3 of the box body 1. The box lid 4 includes an upper cover 5, a pressing locking part 6, a lateral unlocking part 7, and a sealing cover 8. The upper cover 5 is provided with a mounting groove 9. The pressing locking part 6 is movably disposed in the mounting groove 9. The lateral unlocking part 7 is disposed on the side of the pressing locking part 6. The sealing cover 8 is located in the storage cavity 2 and is linked with the pressing locking part 6. When the pressing locking part 6 is pressed down to the locked position, the sealing cover 8 closes the opening 3. When the lateral unlocking part 7 is subjected to lateral pressing force, it unlocks the pressing locking part 6, and the sealing cover 8 opens the opening 3.

[0055] In the above technical solution, the storage box is equipped with a pressing locking part 6 and a side unlocking part 7. The lid of the storage box is closed by pressing down on the pressing locking part 6, and the lid is opened by pressing the side unlocking part 7. In this way, on the one hand, the user can apply lateral pressure to the side unlocking part 7 by pinching it, and then lift it up while pinching the side unlocking part 7 to easily remove the lid 4, which is more convenient and time-saving, and improves the user experience; on the other hand, the direction of force for closing and opening the lid is different, and the operation position is also different, so it is impossible to open the lid by repeatedly pressing the side unlocking part 7. Pressing the locking part 6 opens the lid. Since the lid of the storage box is opened by applying force to the side unlocking part 7, this position is not easily touched. Therefore, it is not easy to accidentally unlock the box, which can effectively prevent the lid from opening due to accidental touch and improve the reliability of the storage box. On the other hand, by setting the locking part 6 and the side unlocking part 7 independently, the user can avoid unlocking the box by pressing the locking part 6, thereby avoiding the problem of the locking part 6 popping up and causing the user's hand to feel the counter-pushing force, thus improving the user experience.

[0056] In this first embodiment, the opening and closing of the storage box is achieved through the sealing cover 8. Since the pressing and locking part 6 and the sealing cover 8 are linked, when the pressing and locking part 6 is pressed down, it will simultaneously drive the sealing cover 8 to move, causing the shape or position of the sealing cover 8 to change. When the pressing and locking part 6 is pressed into place, the change in the shape or position of the sealing cover 8 is sufficient to form a tight fit between the sealing cover 8 and the inner wall of the storage cavity 2 of the box body 1, thereby realizing the closing operation of the sealing cover 8 on the storage box and ensuring the sealing effect between the box cover 4 and the box body 1. When unlocking is required, the side unlocking part 7 can be operated to unlock the pressing locking part 6, allowing the pressing locking part 6 to move to the unlock position. During the process of the pressing locking part 6 moving to the unlock position, the shape or position of the sealing cover 8 changes again, disengaging from the sealed contact with the storage cavity 2 of the box body 1, thereby putting the sealing cover 8 in the open state, so that the box cover 4 can be easily removed from the box body 1 to realize the opening operation.

[0057] In one embodiment, the upper cover 5 of the box cover 4 is provided with a handle position 27 near the mounting groove 9. The handle position 27 is recessed relative to the top surface of the upper cover 5 and is positioned corresponding to the side unlocking part 7, so that part of the side unlocking part 7 is exposed in the recessed space of the handle position 27, thereby facilitating the unlocking operation of the side unlocking part 7. The design of the handle position 27 provides a force application position for the side unlocking part 7, making it easier for the user to operate the side unlocking part 7 and reducing the difficulty of operating the side unlocking part 7. Since only part of the side unlocking part 7 is located at the handle position 27, the other part is still blocked by the inner wall of the mounting groove 9, which can prevent the side unlocking part 7 from disengaging from the side of the pressing locking part 6, thereby improving the structural stability of the side unlocking part 7 and the reliability during operation.

[0058] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, pressing the pressing locking part 6 causes the pressing locking part 6 and the lateral unlocking part 7 to move together to the locked position. The lateral unlocking part 7 locks with the upper cover 5. When the lateral unlocking part 7 is subjected to lateral pressing force, the lateral unlocking part 7 unlocks with the upper cover 5, thereby unlocking the pressing locking part 6.

[0059] With the above configuration, pressing the pressing locking part 6 causes the pressing locking part 6 and the side unlocking part 7 to move together to the locked position, and the upper cover 5 locks the side unlocking part 7 to lock the pressing locking part 6. Thus, under the action of the pressing locking part 6, the sealing cover 8 is also kept in the closed state. By pressing the side unlocking part 7, the upper cover 5 can unlock the side unlocking part 7 to unlock the pressing locking part 6, so that the pressing locking part 6 can reach the unlocked position. Under the action of the pressing locking part 6, the sealing cover 8 is in the open state. In this way, on the one hand, the user can apply lateral pressure to the side unlocking part 7 by pinching it, and then lift it up while pinching the side unlocking part 7 to easily remove the lid 4, which is more convenient and time-saving, improving the user experience. On the other hand, the direction of force for closing and opening the lid is different, and the operation position is also different. Therefore, it is impossible to open the lid by repeatedly pressing the locking part 6. Since the opening of the storage box is achieved by applying lateral force to the side unlocking part 7, this position is not easy to be touched. Therefore, it is not easy to accidentally unlock the box, which can effectively prevent the storage box from opening due to accidental touch, improving the reliability of the storage box. Furthermore, by setting the pressing locking part 6 and the side unlocking part 7 independently, the user can avoid unlocking by pressing the pressing locking part 6, thereby avoiding the problem of the pressing locking part 6 popping up and causing the user's hand to feel the counter-pushing force, thus improving the user experience.

[0060] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the upper cover 5 is provided with a first latching component 33, and the lateral unlocking part 7 includes a second latching component 11 and an elastic component 12. The second latching component 11 is disposed on the side of the pressing and locking part 6, and the elastic component 12 is disposed between the second latching component 11 and the pressing and locking part 6, and provides elastic locking force to the second latching component 11. When the pressing and locking part 6 is pressed down, the second latching component 11 can latch and cooperate with the first latching component 33. When the lateral unlocking part 7 is pressed, the second latching component 11 can disengage from the first latching component 33, and the pressing and locking part 6 can drive the sealing cover 8 to open the opening 3.

[0061] In this first embodiment, when the pressing locking part 6 is pressed down, under the action of the elastic locking force of the elastic member 12, the second latching member 11 can engage with the first latching member 33, so that the pressing locking part 6 is locked on the upper cover 5. Under the driving action of the pressing locking part 6, the sealing cover 8 is also kept in the closed state. By pressing the side unlocking part 7, the elastic locking force of the elastic member 12 can be overcome, so that the second latching member 11 can be unlocked smoothly with the first latching member 33, so that the pressing locking part 6 can reach the unlocked position. Under the driving action of the pressing locking part 6, the sealing cover 8 is in the open state, at which time the box cover 4 can be easily opened from the box body 1.

[0062] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the bottom wall of the upper cover 5 is provided with an operating groove 10, and the second locking component 11 is a hook. When the pressing locking part 6 is pressed down, the hook can pass through the operating groove 10 and hook onto the bottom wall of the upper cover 5 under the elastic locking force of the elastic component 12. When the lateral unlocking part 7 is pressed, the hook can disengage from the bottom wall of the upper cover 5 and reach the avoidance area of ​​the operating groove 10. The pressing locking part 6 can drive the hook to disengage from the operating groove 10.

[0063] In this first embodiment, by opening an operating groove 10 at the bottom of the upper cover 5, a passage can be provided for the hook. During the downward movement of the pressing locking part 6, the hook body can pass through the operating groove 10 and reach the bottom side of the upper cover 5. When the hook body enters the operating groove 10, under the pressure of the side wall of the operating groove 10, the hook overcomes the elastic force of the elastic member 12 and retracts towards the inside of the pressing locking part 6, so that the hook can pass smoothly through the operating groove 10. After the hook body passes through the operating groove 10, since the pressure between the hook body and the side wall of the operating groove 10 disappears, under the elastic action of the elastic member 12, the hook extends outward towards the outside of the pressing locking part 6. The hook body moves to the lower side of the bottom wall of the upper cover 5 and is stopped by the bottom wall of the upper cover 5, so that the pressing locking part 6 is locked on the upper cover 5. Under the driving action of the pressing locking part 6, the sealing cover 8 is also kept in the closed state.

[0064] When unlocking is required, pressing the lateral unlocking part 7 will cause the hook to retract and the hook body to be fully covered by the operating groove 10. At this time, an unlocking force can be applied to the pressing locking part 6, causing the pressing locking part 6 to move upward. Since the hook body is within the coverage of the operating groove 10, the bottom wall of the upper cover 5 will not obstruct the movement of the hook body, allowing it to pass through the operating groove 10. This allows the hook to unlock smoothly from the upper cover 5. After unlocking between the hook and the upper cover 5, the pressing locking part 6 can smoothly reach the unlock position. Under the action of the pressing locking part 6, the sealing cover 8 is in the open state, at which time the box cover 4 can be easily opened from the box body 1.

[0065] In this embodiment, the hook body protrudes outward from the pressing and locking part 6, so that the extension direction of the hook body is opposite to the pressing direction of the side unlocking part 7, facilitating the unlocking operation of the pressing and locking part 6 by the lateral pressing of the side unlocking part 7. The size of the operating groove 10 is adapted to the size of the maximum cross-section of the hook body, thereby ensuring the structural strength of the bottom wall of the upper cover 5 while smoothly realizing the locking and unlocking operation of the hook body.

[0066] The aforementioned elastic component 12 is, for example, a spring, or it can be replaced by a component with elastic function such as an elastic block.

[0067] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, an avoidance groove 13 is provided on the side wall of the mounting groove 9, and a first stop part 14 is formed at the bottom of the avoidance groove 13. The hook passes through the operating groove 10 and hooks onto the bottom wall of the first stop part 14.

[0068] In this first embodiment, by providing the clearance groove 13, the hook body of the catch can be positioned within the clearance groove 13 when it is located within the mounting groove 9. This avoids excessive pressure exerted on the hook body by the inner wall of the mounting groove 9, reduces the compressive force applied by the catch to the elastic component 12 when the hook body is within the mounting groove 9, reduces the compression effect of the elastic component 12 when the pressing locking part 6 is in the unlocked state, and improves the service life of the elastic component 12. The clearance groove 13 extends to the bottom of the mounting groove 9, and the bottom wall of the mounting groove 9 at the end of the clearance groove 13 can form a first stop part 14. After the hook body of the catch passes through the operating groove 10, it can be hooked by the first stop part 14.

[0069] It should be noted that in Embodiment 1 of the present invention, the first stop portion 14 forms the first snap-fit ​​component 33.

[0070] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the side wall of the pressing locking part 6 is provided with a receiving groove 15, the bottom wall of the receiving groove 15 is provided with a guide hole 16, a guide post 17 is provided on the side of the hook facing the receiving groove 15, the guide post 17 is slidably disposed in the guide hole 16, the elastic member 12 is sleeved on the outside of the guide post 17, the first end of the elastic member 12 abuts against the hook, and the second end of the elastic member 12 abuts against the bottom wall of the receiving groove 15.

[0071] In this first embodiment, by providing a receiving groove 15, a space is provided for the hook, ensuring that the hook does not protrude laterally from the pressing and locking part 6, thus forming a better overall structure with the pressing and locking part 6 and improving its appearance. By providing a guide post 17 on the hook and a guide hole 16 on the bottom wall of the receiving groove 15, the lateral movement of the hook can be guided by the guide post 17 and the guide hole 16, ensuring the reliability of the lateral movement of the hook and facilitating the pressing operation of the lateral unlocking part 7. The bottom wall of the receiving groove 15 refers to the wall of the bottom of the receiving groove 15. In this first embodiment, the bottom wall of the receiving groove 15 is a vertical wall, perpendicular to the extension direction of the guide post 17.

[0072] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the pressing locking part 6 includes a pressing cover 18, which is slidably disposed in the mounting groove 9. A receiving cavity is formed between the pressing cover 18 and the upper cover 5. A connecting rod 20 is provided on the sealing cover 8. The connecting rod 20 passes through the bottom wall of the upper cover 5 and extends into the receiving cavity. A lever 19 is provided in the receiving cavity. The fulcrum of the lever 19 is located on the upper cover 5. The first end of the lever 19 is hinged to the connecting rod 20, and the second end of the lever 19 is engaged with the pressing cover 18. The sealing cover 8 includes a flexible sealing part 26, which is a cone-shaped structure that gradually expands in the direction close to the upper cover 5. The upper cover 5 includes a convex ring 21, which is provided corresponding to the flexible sealing part 26. When the pressing locking part 6 is pressed down, the second end of the lever 19 is pressed down, and the first end of the lever 19 is lifted up, which drives the sealing cover 8 to move upward. The flexible sealing part 26 expands outward under the squeezing action of the convex ring 21 and forms a tight seal with the inner wall of the storage cavity 2 of the box body 1.

[0073] In this first embodiment, the pressing locking part 6 and the sealing cover 8 are linked by a lever 19. The lever 19 is set on the bottom wall of the upper cover 5 through a fulcrum. The second end of the lever 19 that cooperates with the pressing cover 18 is raised, and the first end that is connected to the connecting rod 20 is lowered. When the pressing locking part 6 is pressed down, the pressing cover 18 presses down the lever 19, and the second end of the lever 19 is pressed down, which drives the first end of the lever 19 to rise. Under the driving action of the lever 19, the connecting rod 20 moves upward, which drives the sealing cover 8 to move upward. During the upward movement of the sealing cover 8, the flexible sealing part 26 expands outward under the squeezing action of the convex ring 21, and squeezes against the inner wall of the storage cavity of the box body 1 to form a tight seal, thereby realizing the closing of the storage box. When the locking part 6 is unlocked by pressing, the locking part 6 can be controlled to move upward. At this time, the force of the downward lever 19 disappears, the upward force of the sealing cover 8 disappears, and the sealing cover 8 can move downward under the action of the lever 19 or external force, and disengage from the squeezing range of the convex ring 21, thereby releasing the squeezing and sealing effect with the box body 1. At this time, the sealing cover 8 retracts and disengages from the box body 1, or the squeezing force between the sealing cover 8 and the box body 1 is greatly reduced, and the friction between the two is greatly reduced, which makes it easy to open the cover.

[0074] In one embodiment, one end of the lever 19 is hinged to the bottom wall of the press cover 18, and the fulcrum of the lever 19 is hinged to the bottom wall of the upper cover 5. In order to facilitate the setting of the lever 19 and avoid the bottom wall of the upper cover 5 from hindering the rotation of the lever 19, a column can be set on the bottom wall of the press cover 18, and the fulcrum of the lever 19 is hinged to the column, thereby providing sufficient space for the rotation of the lever 19.

[0075] In one embodiment, a support block can also be provided on the bottom wall of the press cover 18. The top of the support block is arc-shaped. The first end of the lever 19 is hinged to the connecting rod 20. The middle part of the lever 19 is supported on the top of the support block, and the second end of the lever 19 is suspended.

[0076] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, there are two levers 19, which are symmetrically arranged around the center of the pressing and locking part 6.

[0077] In this first embodiment, the two levers 19 are symmetrically arranged around the center of the pressing and locking part 6, which makes the lifting force of the levers 19 on the sealing cover 8 more balanced during the pressing process and the structure more stable.

[0078] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the bottom wall of the upper cover 5 is provided with an upwardly protruding post 22, and a guide hole 16 is provided inside the post 22. A guide rod 23 is provided on the pressing cover 18, and the guide rod 23 is slidably disposed in the guide hole 16.

[0079] In this first embodiment, a protruding post 22 is provided on the bottom wall of the upper cover 5. The protruding post 22 has a guide hole 16, which extends along the pressing direction of the pressing locking part 6. A guide rod 23 is provided on the pressing cover 18. The guide rod 23 slides with the guide hole 16, which can control the pressing locking part 6 to slide along the guiding direction of the guide hole 16, thereby improving the stability and reliability of the movement direction of the pressing locking part 6.

[0080] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the second end of the lever 19 is L-shaped. Setting the second end of the lever 19 that mates with the pressing cover 18 to be L-shaped increases the contact area between the lever 19 and the pressing cover 18, improving the stability of the mating structure. Furthermore, the L-shaped structure makes the force distribution on the lever 19 more balanced during the pressing process of the pressing cover 18, resulting in a more uniform force application from the pressing cover 18 to the lever 19.

[0081] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, a guide slope 28 is provided on the outer wall of the end of the convex ring 21 facing the flexible sealing part 26. When the pressing locking part 6 is in the unlocked state, the outer edge of the end of the flexible sealing part 26 facing the convex ring 21 is located outside the outer wall of the convex ring 21.

[0082] In this first embodiment, a guide slope 28 is formed on the outer edge of the end of the convex ring 21 facing the flexible sealing part 26. When the flexible sealing part 26 moves towards the convex ring 21, the guide slope 28 guides the movement of the flexible sealing part 26, guiding it to expand outward under the action of the guide slope 28, thus forming a compression seal on the inner wall of the storage cavity 2 of the box body 1. The guide slope 28 of the convex ring 21 reduces the difficulty of the flexible sealing part 26 moving towards the convex ring 21 and expanding outward, avoiding interference between the flexible sealing part 26 and the convex ring 21 during movement, and improving the reliability of the movement.

[0083] In one embodiment, the inner wall surface of the flexible sealing part 26 facing the convex ring 21 is also provided with a guide slope, which can further reduce the difficulty of fitting the flexible sealing part 26 and the convex ring 21.

[0084] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the protruding ring 21 extends into the storage cavity 2, and the gap between the outer wall of the protruding ring 21 and the inner wall of the storage cavity 2 is less than the thickness of the flexible sealing part 26.

[0085] In this first embodiment, since the convex ring 21 extends into the storage cavity 2, when the flexible sealing part 26 is sleeved on the outer periphery of the convex ring 21 and expands outward under the support of the convex ring 21, the part that crosses the bottom surface of the convex ring 21 will enter the gap between the outer wall of the convex ring 21 and the inner wall of the storage cavity 2. The gap between the outer wall of the convex ring 21 and the inner wall of the storage cavity 2 is less than the thickness of the flexible sealing part 26. Therefore, the flexible sealing part 26 that enters the gap will be deformed by the squeezing force between the outer wall of the convex ring 21 and the inner wall of the storage cavity 2, thereby pressing the inner wall of the storage cavity 2 and forming a compression seal with the inner wall of the storage cavity 2, achieving a good closing effect.

[0086] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, a return spring 29 is provided between the upper cover 5 and the sealing cover 8. The first end of the return spring 29 abuts against the bottom wall of the upper cover 5, and the second end of the return spring 29 abuts against the sealing cover 8.

[0087] In this first embodiment, the second end of the lever 19 is a cantilever structure and there is no direct connection between it and the pressing cover 18. When the pressing locking part 6 is in the unlocked state, the hook body of the hook comes out from the bottom wall of the upper cover 5 along the operating groove 10, releasing the locking effect on the pressing locking part 6. At this time, under the elastic force of the return spring 29, the sealing cover 8 is pressed down and moves away from the upper cover 5. During this process, the connecting rod 20 is driven down by the sealing cover 8, and the first end of the lever 19 connected to the connecting rod 20 also moves down. The second end of the lever 19 is lifted up, driving the pressing cover 18 to move up, thereby reaching the unlocked position, which facilitates the automatic opening operation of the storage box.

[0088] As shown in Figures 1 to 7, in Embodiment 1 of the present invention, the sealing cover 8 includes an inner cover 24, a support cover 25, and a flexible sealing part 26. The inner cover 24 is disposed inside the support cover 25 and is detachably connected to the support cover 25. The flexible sealing part 26 is installed on the outer periphery of the support cover 25. And / or, lateral unlocking parts 7 are respectively provided on both sides of the pressing locking part 6.

[0089] Specifically, in Embodiment 1 of the present invention, an annular groove 30 is provided on the outer periphery of the support cover 25, and the flexible sealing part 26 includes an inner ring flange 31, which is engaged in the annular groove 30 to realize the connection between the flexible sealing part 26 and the support cover 25.

[0090] In this first embodiment, the inner cover 24, the support cover 25, and the flexible sealing part 26 adopt a split structure, which can reduce the molding difficulty of each part. In addition, the selection of materials for the inner cover 24, the support cover 25, and the flexible sealing part 26 is more flexible, making it easier to select suitable materials according to the characteristics of the sealing cover 8 and improve the sealing performance of the sealing cover 8.

[0091] The inner cover 24 and the support cover 25 can be made of hard plastic to provide stable support, while the flexible sealing part 26 can be made of soft plastic to provide good deformation capability and achieve a good compression seal with the inner wall of the storage cavity 2 of the box body 1.

[0092] In one embodiment, lateral unlocking parts 7 are provided on both sides of the pressing locking part 6.

[0093] In this first embodiment, lateral unlocking parts 7 are provided on both sides of the pressing locking part 6, which can avoid the problem of insufficient reliability caused by setting a lateral unlocking part 7 on only one side. When it is necessary to unlock the pressing locking part 6, both lateral unlocking parts 7 on both sides need to be pressed at the same time to unlock the pressing locking part 6. The overall structure of the storage box has better stability and reliability.

[0094] As shown in Figures 19 and 20, in Embodiment 1 of the present invention, the lid of the storage box further includes a hook structure 44 connected to the pressing and locking part 6, and the upper cover 5 is also provided with a sliding groove 45 communicating with the mounting groove. The hook structure 44 engages with the sliding groove 45 and slides with the sliding groove 45. In this way, during the movement of the pressing and locking part 6, the sliding groove 45 can play a guiding role, and the hook structure 44 can prevent the pressing and locking part 6 from falling off the upper cover 5.

[0095] Example 2

[0096] As shown in Figures 8 to 13, the difference between Embodiment 2 and Embodiment 1 is that the first snap-fit ​​component 33 is connected to the bottom wall of the mounting groove 9 and extends away from the sealing cover 8; the second snap-fit ​​component 11 is rotatably connected to the pressing and locking part 6, and the pressing and locking part 6 is provided with a second stop part 32 on the side facing the sealing cover 8. The second stop part 32 extends towards the side where the sealing cover 8 is located, and the elastic component 12 is disposed between the second snap-fit ​​component 11 and the second stop part 32.

[0097] With the above configuration, pressing down the locking part 6 causes the second latching member 11 to engage with the first latching member 33, so that the elastic member 12 keeps the locking part 6 in the locked position. When it is necessary to unlock the locking part 6, the second latching member 11 can be pressed from the side to make the second latching member 11 rotate against the elastic force of the elastic member 12, so that the first latching member 33 and the second latching member 11 are disengaged, thereby allowing the locking part 6 to switch from the locked position to the unlocked position.

[0098] As shown in Figures 8 to 13, in Embodiment 2 of the present invention, one of the first snap-fit ​​component 33 and the second snap-fit ​​component 11 includes a hook member 34, and the other of the first snap-fit ​​component 33 and the second snap-fit ​​component 11 is provided with a slot 38. The hook member 34 can engage with the slot 38 or disengage from the slot 38. In this way, the connection and disconnection between the first snap-fit ​​component 33 and the second snap-fit ​​component 11 can be realized.

[0099] In this second embodiment, the end face of the first snap-fit ​​component 33 away from the sealing cover 8 is a slope. This slope extends obliquely from the bottom of the lateral mounting groove 9 where the lateral unlocking part 7 is located. The first snap-fit ​​component 33 is provided with a slot 38, which is located on the side of the slope near the sealing cover 8. The second snap-fit ​​component 11 includes a hook component 34 and a stop component 43 connected to the hook component 34. The stop component 43 is located on the side of the hook component 34 facing the second stop part 32. The elastic member 12 is located between the stop component 43 and the second stop part 32. The snap-fit ​​position of the hook component 34 and the slot 38 is located between the pivot point between the second snap-fit ​​component 11 and the pressing locking part 6 and the elastic member 12.

[0100] When unlocking is required, press the hook member 34 to rotate relative to the pressing and locking part 6 towards the side where the elastic member 12 is located, so that the hook member 34 can disengage from the slot 38, thereby unlocking the pressing and locking part 6. When the pressing and locking part 6 reaches the unlock position smoothly, the sealing cover 8 is in the open state under the action of the pressing and locking part 6, and the box cover 4 can be easily opened from the box body 1.

[0101] During the process of pressing the locking part 6 towards the side where the sealing cover 8 is located, the hook member 34 first abuts against the inclined surface. As the hook member 34 continues to move towards the side where the sealing cover 8 is located, the hook member 34 rotates towards the side where the elastic member 12 is located under the pressure of the inclined surface. At this time, the stop member 43 also moves towards the side where the elastic member 12 is located, and the elastic member 12 is compressed. When the hook member 34 moves to the location of the slot 38, the hook member 34 is engaged in the slot 38. Since the pressure between the hook member 34 and the inclined surface disappears, under the elastic action of the elastic member 12, the hook member 34 and the slot 38 are locked together, and the pressing locking part 6 is locked on the upper cover 5. Under the driving action of the pressing locking part 6, the storage box is in the closed state.

[0102] In this second embodiment, the hook member 34 protrudes outward toward the outside of the pressing locking part 6, so that the extension direction of the hook member 34 is opposite to the pressing direction of the side unlocking part 7, which facilitates the unlocking operation of the pressing locking part 6 by the side pressing of the side unlocking part 7.

[0103] In this second embodiment, the stop member 43 and the second stop part 32 are correspondingly provided, and the stop member 43 and the second stop part 32 have positioning posts. The second stop part 32 is located inside the stop member 43. One end of the elastic member 12 is sleeved on the positioning post of the stop member 43, and the other end of the elastic member 12 is sleeved on the positioning post of the second stop part 32.

[0104] In one embodiment, the second snap-fit ​​component 11 and the second stop portion 32 are both baffles.

[0105] As shown in Figures 8 to 13, in Embodiment 2 of the present invention, the hook member 34 is provided with a rotating shaft 41 at one end near the sealing cover 8, and the pressing locking part 6 is provided with a mounting hole 40 at one end near the sealing cover 8. The mounting hole 40 is provided in correspondence with the rotating shaft 41, and the rotating shaft 41 passes through the mounting hole 40. Through the above arrangement, the pressing locking part 6 and the lateral unlocking part 7 are rotatedly connected.

[0106] The other structures of Embodiment 2 of the present invention are the same as those of Embodiment 1, and will not be described again here.

[0107] Example 3

[0108] As shown in Figures 14 to 20, the difference between Embodiment 3 and Embodiment 1 is that the pressing locking part 6 is movably disposed relative to the side unlocking part 7. When the pressing locking part 6 is pressed to the locked position, the pressing locking part 6 and the side unlocking part 7 are locked together. When the side unlocking part 7 is subjected to lateral pressing force, the pressing locking part 6 and the side unlocking part 7 are unlocked.

[0109] With the above settings, pressing the pressing locking part 6 to the locked position locks the lateral unlocking part 7 against the pressing locking part 6, allowing the upper cover 5 to abut against the flexible sealing part 26. This allows the flexible sealing part 26 to expand outwards under the pressure of the upper cover 5, sealing it against the box body. When it is necessary to retract the flexible sealing part 26, i.e., to release the seal between the flexible sealing part 26 and the box body, the lateral unlocking part 7 can be pressed from the side, unlocking the pressing locking part 6. At this time, the upper cover 5 can disengage from the flexible sealing part 26, facilitating the opening operation. Thus, on the one hand, the user can apply lateral pressure to the lateral unlocking part 7 by pinching it. The lid 4 can be easily removed by simultaneously lifting the unlocking part 7, which is more convenient and time-saving, improving the user experience. On the other hand, the force applied to closing and opening the lid are different, and the operation positions are also different. Therefore, it is impossible to open the lid by repeatedly pressing the locking part 6. Since the opening of the storage box is achieved by applying force to the side-to-side unlocking part 7, this position is not easy to touch. Therefore, it is not easy to accidentally unlock the box, which can effectively prevent the storage box from opening due to accidental touch, improving the reliability of the storage box. Furthermore, by setting the pressing locking part 6 and the side unlocking part 7 independently, the user can avoid unlocking by pressing the pressing locking part 6, thereby avoiding the problem of the pressing locking part 6 popping up and causing the user's hand to feel the counter-pushing force, thus improving the user experience.

[0110] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, the pressing locking part 6 has a latching member 46, and the lateral unlocking part 7 includes: an unlocking component 35, which is rotatably connected to the upper cover 5. Along the axial direction of the cover 4, the unlocking component 35 has a pressing part 36 and a latching part 37 disposed opposite to each other. The pivot point between the unlocking component 35 and the upper cover 5 is located between the pressing part 36 and the latching part 37; and an elastic component 12, which provides a latching force to the latching part 37. When the pressing locking part 6 is pressed down to the locked position, the latching member 46 and the latching part 37 are latched together. When the pressing part is subjected to lateral pressing force, the latching member 46 and the latching part 37 are disengaged.

[0111] With the above settings, when the pressing locking part 6 is pressed down, the latching member 46 of the pressing locking part 6 can engage with the latching part 37, so that the pressing locking part 6 is kept in the locked position by the elastic member 12. When it is necessary to unlock the pressing locking part 6, the pressing part 36 of the unlocking member 35 can be pressed from the side, so that the unlocking member 35 can overcome the elastic force of the elastic member 12 and rotate, so that the latching part 37 can move away from the latching member 46, so that the latching part 37 releases the latching member 46, thereby allowing the pressing locking part 6 to switch from the locked position to the unlocked position.

[0112] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, the latching member 46 is a latch hook, which is configured to engage with the bottom end of the unlocking member 35. This facilitates the engagement between the pressing locking part 6 and the unlocking member 35. The bottom end of the unlocking member 35 forms the aforementioned latching portion 37.

[0113] In one embodiment, a slot may be provided on the unlocking component 35, and the hook may engage with the slot.

[0114] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, one end of the elastic member 12 abuts against the snap-fit ​​portion 37, and the other end of the elastic member 12 abuts against the upper cover 5. In this way, the elastic member 12 can keep the pressing locking portion 6 in the locked position.

[0115] In one embodiment, the elastic member 12 may be disposed between the pivot point between the unlocking member 35 and the upper cover 5 and the pressing part 36. The two ends of the elastic member 12 are respectively connected to the unlocking member 35 and the upper cover 5, and the elastic member 12 is in a stretched state when the pressing locking part 6 is held in the locked position.

[0116] The aforementioned elastic component 12 is, for example, a spring, or it can be replaced by a component with elastic function such as an elastic block.

[0117] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, the unlocking component 35 is provided with a limiting part 39, and the elastic component 12 is limited and engaged with the limiting part 39. In this way, the elastic component 12 can be prevented from disengaging from the unlocking component 35 during the pressing process, thereby increasing the structural stability.

[0118] Preferably, in Embodiment 3 of the present invention, the limiting part 39 is an annular groove provided on the unlocking part 35, and one end of the elastic part 12 is located in the annular groove.

[0119] As shown in Figure 18, in Embodiment 3 of the present invention, the pressing locking part 6 is movably disposed relative to the upper cover 5 along the axial direction of the lid; a stop member 43 is provided on the side of the unlocking part 35 facing the pressing locking part 6, and the stop member 43 is located between the pressing part 36 and the locking part 37 to prevent the pressing locking part 6 from disengaging from the lateral unlocking part 7.

[0120] With the above configuration, when the pressing part 36 of the unlocking member 35 is pressed from the side to unlock the pressing locking part 6, the pressing locking part 6 pops up, and the stop member 43 can prevent the pressing locking part 6 from disengaging from the side unlocking part 7.

[0121] Preferably, in Embodiment 3 of the present invention, the stop member 43 is a convex rib.

[0122] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, the inner wall of the mounting groove 9 is provided with a mounting hole 40, and the unlocking component 35 is provided with a rotating shaft 41, which is rotatably engaged with the mounting hole 40. In this way, a rotatable connection can be realized between the unlocking component 35 and the upper cover 5, so that the unlocking component 35 can engage or disengage with the pressing locking part 6.

[0123] Preferably, in Embodiment 3 of the present invention, the unlocking component 35 is provided with a rotating shaft 41 on both sides, and the inner walls on both sides of the mounting groove 9 are provided with mounting holes 40, and the two rotating shafts 41 are rotatably connected to the two mounting holes 40.

[0124] As shown in Figures 14 to 20, in Embodiment 3 of the present invention, a guide groove 42 is also provided on the inner wall of the mounting groove 9. Along the axial direction of the cover 4, the guide groove 42 extends from the mounting hole 40 to the top wall of the upper cover 5. In this way, when installing the unlocking component 35, the rotating shaft 41 can slide along the guide groove 42 to facilitate the installation of the rotating shaft 41 of the unlocking component 35 into the mounting hole 40.

[0125] Preferably, in Embodiment 3 of the present invention, the hook structure 44 and the latching member are located on different sides of the pressing and locking part 6, so that interference between the hook structure 44 and the lateral unlocking part 7 can be avoided.

[0126] The other structures of Embodiment 3 of the present invention are the same as those of Embodiment 1, and will not be described again here.

[0127] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: The storage box is provided with a pressing locking part and a side unlocking part. The lid of the storage box is closed by pressing down on the pressing locking part, and the lid is opened by pressing the side unlocking part. In this way, on the one hand, the user can apply lateral pressure to the side unlocking part by pinching it, and can easily remove the lid by lifting it while pinching the side unlocking part, which is more convenient and time-saving, and improves the user experience; on the other hand, the direction of force for closing and opening the lid is different, and the operating position is also different. Therefore, the lid cannot be opened by repeatedly pressing the locking part. Since the lid of the storage box is opened by applying force to the side unlocking part, this position is not easily touched. Therefore, it is not easy to accidentally unlock the box, which can effectively prevent the lid from being opened due to accidental touch and improve the reliability of the storage box. On the other hand, by setting the locking part and the side unlocking part independently, the user can avoid unlocking by pressing the locking part, thus avoiding the problem of the locking part popping up and causing the user's hand to feel the counter-pushing force, thereby improving the user experience.
