DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] See also Figures 1 to 7 As shown, according to an embodiment of the utility model, the storage box includes: a box body 1, having a storage cavity 2 and an opening 3 connected to the storage cavity 2; a box cover 4, which is arranged at the opening 3 of the box body 1, and the box cover 4 includes an upper cover 5, a push-locking portion 6, a lateral unlocking portion 7 and a sealing cover 8. The upper cover 5 is provided with a mounting groove 9, the push-locking portion 6 is movably arranged in the mounting groove 9, the lateral unlocking portion 7 is arranged on the side of the push-locking portion 6, and the sealing cover 8 is located in the storage cavity 2 and forms a linkage with the push-locking portion 6. When the push-locking portion 6 is pressed down to the locking position, the sealing cover 8 closes the opening 3. When the lateral unlocking portion 7 is subjected to lateral pressing force, the push-locking portion 6 is unlocked, and the sealing cover 8 opens the opening 3.

[0032] The storage box is provided with a push-locking part 6 and a lateral unlocking part 7. The closing of the storage box is achieved by pressing the push-locking part 6 downward, and the opening of the storage box is achieved by pressing the lateral unlocking part 7 sideways. The force directions of closing and opening the cover are different, and the operation positions are also different. Therefore, the cover cannot be opened by pressing the push-locking part 6 multiple times. Since the opening of the storage box is achieved by applying force to the lateral unlocking part 7 from the side, this position is not easily touched, and therefore the problem of accidental touch unlocking is not likely to occur. This can effectively prevent the storage box lid from opening due to accidental touch, thereby improving the reliability of the storage box.

[0033] In the present embodiment, the opening and closing of the storage box is realized by 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 downward, the sealing cover 8 will be driven to move at the same time, so that the shape or position of the sealing cover 8 changes. 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 storage box by the sealing cover 8 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 used to unlock the push locking part 6 by manipulating the side unlocking part 7, so that the push locking part 6 can move to the unlocking position. In the process of the push locking part 6 moving to the unlocking position, as the push locking part 6 moves, the shape or position of the sealing cover 8 changes again, and it is separated from the airtight contact with the storage cavity 2 of the box body 1, so that the sealing cover 8 is in an open state, and the box cover 4 can be easily removed from the box body 1 to realize the open cover operation.

[0034] In one embodiment, a handle position 27 is provided at a position of the upper cover of the box cover 4 near the mounting groove 9. The handle position 27 is concave relative to the top surface of the upper cover. The handle position 27 is provided corresponding to the position of the lateral unlocking portion 7, so that the lateral unlocking portion 7 is partially exposed in the concave space of the handle position 27, thereby facilitating the unlocking operation of the lateral unlocking portion 7. The provision of the handle position 27 can provide a force application position for the lateral unlocking portion 7, making it more convenient for the user to operate the lateral unlocking portion 7, thereby reducing the difficulty of operating the lateral unlocking portion 7. Since only a portion of the lateral unlocking portion 7 is located at the handle position 27, the other portion is still blocked by the inner wall of the mounting groove 9, which can prevent the lateral unlocking portion 7 from escaping from the side of the pressing locking portion 6, thereby improving the structural stability of the lateral unlocking portion 7 and the reliability during operation.

[0035] In one embodiment, an operating groove 10 is provided at the bottom of the upper cover 5, and the lateral unlocking portion 7 includes a hook 11 and an elastic member 12. The hook 11 is arranged on the side of the push-locking portion 6, and the elastic member 12 is arranged between the hook 11 and the push-locking portion 6, and provides an elastic locking force to the hook 11. When the push-locking portion 6 is pressed downward, the hook 11 can pass through the operating groove 10 and hook on the bottom wall of the upper cover 5 under the elastic locking force of the elastic member 12. When the lateral unlocking portion 7 is pressurized, the hook 11 can be separated from the bottom wall of the upper cover 5 and reach the avoidance area of ​​the operating groove 10. The push-locking portion 6 can drive the hook 11 to disengage from the operating groove 10 and drive the sealing cover 8 to open the opening 3.

[0036] In this embodiment, by opening the operating groove 10 at the bottom of the upper cover 5, a passage can be provided for the hook 11 to pass through. When the pressing and locking part 6 is in the downward process, the hook body of the hook 11 can pass through the operating groove 10 and reach the bottom surface side of the bottom of the upper cover 5. When the hook body of the hook 11 enters the operating groove 10, under the pressure of the side wall of the operating groove 10, the hook 11 overcomes the elastic force of the elastic member 12 and retracts to the inner side of the pressing and locking part 6, so that the hook 11 can smoothly move out of the operating groove 10. The locking portion 6 is pressed against the bottom wall of the upper cover 5 and the locking portion 6 is locked on the upper cover 5. The sealing cover 8 is also kept in the closed state under the driving action of the locking portion 6.

[0037] When unlocking is required, by pressing the lateral unlocking portion 7, the hook 11 can be retracted, and the hook body of the hook 11 is completely within the coverage of the operating slot 10. At this time, an unlocking force can be applied to the push-lock portion 6 to make the push-lock portion 6 move upward. Since the hook body is within the coverage of the operating slot 10, the bottom wall of the upper cover 5 will not hinder the movement of the hook body and can pass through the operating slot 10, so that the hook 11 can be smoothly unlocked from the upper cover 5. After unlocking is achieved between the hook 11 and the upper cover 5, the push-lock portion 6 can smoothly reach the unlocking position. Driven by the push-lock portion 6, the sealing cover 8 is in an open state. At this time, the box cover 4 can be conveniently opened from the box body 1.

[0038] The hook body of the hook 11 in this embodiment protrudes toward the outside of the pressing locking portion 6, so that the extending direction of the hook body is opposite to the pressing direction of the lateral unlocking portion 7, which facilitates the unlocking operation of the pressing locking portion 6 by lateral pressing of the lateral unlocking portion 7. The size of the operating slot 10 is adapted to the size of the maximum cross-section of the hook body, so that the locking and unlocking operations of the hook body of the hook 11 can be smoothly achieved on the basis of ensuring the structural strength of the bottom wall of the upper cover 5.

[0039] The elastic member 12 is, for example, a spring, and may also be replaced by a component with elastic function such as an elastic block.

[0040] In one embodiment, an avoidance groove 13 is opened on the side wall of the installation groove 9 , and a stopper 14 is formed at the bottom of the avoidance groove 13 . The hook 11 passes through the operating groove 10 and is hooked on the bottom wall of the stopper 14 .

[0041] In this embodiment, by providing the avoidance groove 13, the hook body of the hook 11 can be located in the avoidance groove 13 when it is located in the installation groove 9, so as to avoid the inner wall of the installation groove 9 from exerting a large squeezing force on the hook body, reduce the compression force exerted by the hook 11 on the elastic member 12 when the hook body is located in the installation groove 9, reduce the compression effect of the elastic member 12 when the pressing locking portion 6 is in the unlocked state, and improve the service life of the elastic member 12. The avoidance groove 13 extends to the bottom of the installation groove 9, but the bottom wall of the installation groove 9 allows the bottom wall of the installation groove 9 at the end of the avoidance groove 13 to form a stopper 14, and after the hook body of the hook 11 passes through the operating groove 10, the hook body can be hooked by the stopper 14.

[0042] In one embodiment, a accommodating groove 15 is provided on the side wall of the press-locking portion 6, a guide hole 16 is provided on the bottom wall of the accommodating groove 15, a guide column 17 is provided on the side of the hook 11 facing the accommodating groove 15, the guide column 17 is slidably set in the guide hole 16, the elastic member 12 is sleeved outside the guide column 17, the first end of the elastic member 12 abuts the hook 11, and the second end of the elastic member 12 abuts the bottom wall of the accommodating groove 15.

[0043] In this embodiment, by providing the receiving groove 15, a receiving space can be provided for the setting of the hook 11, so that the hook 11 will not protrude from the pressing and locking part 6 in the lateral direction, and can form a better whole with the pressing and locking part 6, and the appearance performance is better. By providing a guide column 17 on the hook 11 and providing a guide hole 16 on the bottom wall of the receiving groove 15, the lateral movement of the hook 11 can be guided by the guiding cooperation of the guide column 17 and the guide hole 16, so as to realize the reliability of the lateral movement of the hook 11 and facilitate the pressing operation of the lateral unlocking part 7. The bottom wall of the receiving groove 15 refers to the wall body of the bottom of the receiving groove 15. In this embodiment, the bottom wall of the receiving groove 15 is a vertical wall and is perpendicular to the extension direction of the guide column 17.

[0044] In one embodiment, the push-locking portion 6 includes a push-locking cover 18, which is slidably arranged in the mounting groove 9, and a receiving chamber is formed between the push-locking cover 18 and the upper cover 5. A connecting rod 20 is arranged on the sealing cover 8, and the connecting rod 20 passes through the bottom wall of the upper cover 5 and extends into the receiving chamber. A lever 19 is arranged in the receiving chamber, and the fulcrum of the lever 19 is located at 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 matched with the push-locking cover 18. The sealing cover 8 includes a flexible sealing portion 26, and the flexible sealing portion 26 is a conical structure that gradually expands in a direction close to the upper cover 5. The upper cover 5 includes a convex ring 21, and the convex ring 21 is arranged corresponding to the flexible sealing portion 26. When the push-locking portion 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, driving the sealing cover 8 upward. The flexible sealing portion 26 expands outward under the squeezing action of the convex ring 21, and forms a compression seal with the inner wall of the storage chamber 2 of the box body 1.

[0045] In this embodiment, the push-locking part 6 and the sealing cover 8 are linked by a lever 19. The lever 19 is arranged on the bottom wall of the upper cover 5 through a fulcrum. The second end of the lever 19 that cooperates with the push-locking cover 18 tilts upward, and the first end connected with the connecting rod 20 sinks downward. When the push-locking part 6 is pressed downward, the push-locking cover 18 presses down the lever 19, and the second end of the lever 19 presses down, driving the first end of the lever 19 to lift up. Under the driving action of the lever 19, the connecting rod 20 moves upward, driving the sealing cover 8 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 is squeezed with 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. After the push-locking part 6 is unlocked, the push-locking part 6 can be controlled to move upward. At this time, the force of the downward-pressing lever 19 disappears, and the upward-lifting force of the sealing cover 8 disappears. The sealing cover 8 can move downward under the action of the lever 19 or an external force and escape from the extrusion range of the convex ring 21, thereby releasing the extrusion sealing effect with the box body 1. At this time, the sealing cover 8 is retracted inward and breaks away from contact with the box body 1, or the extrusion effect between the sealing cover 8 and the box body 1 is greatly reduced, and the friction between the two is greatly reduced, which can facilitate the opening operation.

[0046] In one embodiment, one end of the lever 19 is hinged to the bottom wall of the pressing 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 pressing 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.

[0047] In one embodiment, a support block can also be set on the bottom wall of the pressing 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.

[0048] In one embodiment, the number of the levers 19 is two, and the two levers 19 are symmetrically arranged around the center of the push-lock portion 6 .

[0049] In this embodiment, the two levers 19 are symmetrically arranged around the center of the pressing and locking portion 6, so that the pulling force of the levers 19 on the sealing cover 8 during the pressing process can be more balanced and the structure can be more stable.

[0050] In one embodiment, the bottom wall of the upper cover 5 is provided with a boss 22 protruding upward, a guide hole 16 is provided in the boss 22 , and a guide rod 23 is provided on the pressing cover 18 , and the guide rod 23 is slidably disposed in the guide hole 16 .

[0051] In this embodiment, a boss 22 is provided on the bottom wall of the upper cover 5, and the boss 22 has a guide hole 16, which extends along the pressing direction of the press-locking part 6. A guide rod 23 is provided on the press cover 18, and the guide rod 23 is slidably matched with the guide hole 16, so as to control the press-locking part 6 to slide along the guide direction of the guide hole 16, thereby improving the stability and reliability of the movement direction of the press-locking part 6.

[0052] The second end of the lever 19 is L-shaped. Setting the second end of the lever 19 that cooperates with the pressing cover 18 to be L-shaped can increase the contact area between the lever 19 and the pressing cover 18 and improve the stability of the matching structure between the lever 19 and the pressing cover 18. In addition, the L-shaped structure makes the force structure of the lever 19 more balanced during the pressing process of the pressing cover 18, and the force applied by the pressing cover 18 to the lever 19 is more uniform.

[0053] In one embodiment, a guide slope 28 is provided on the outer wall of one end of the convex ring 21 facing the flexible sealing portion 26 . When the locking portion 6 is in the unlocked state, the outer edge of the end of the flexible sealing portion 26 facing the convex ring 21 is located outside the outer wall of the convex ring 21 .

[0054] In this embodiment, a guiding slope 28 is formed on the outer edge of one end of the convex ring 21 facing the flexible sealing part 26, and when the flexible sealing part 26 moves toward the convex ring 21, the guiding slope 28 can be used to guide the movement of the flexible sealing part 26, and the flexible sealing part 26 is guided to expand outward under the action of the guiding slope 28, so as to form an extrusion seal on the inner wall of the storage cavity 2 of the box body 1. The guiding slope 28 of the convex ring 21 can reduce the difficulty of the flexible sealing part 26 moving toward the convex ring 21 and expanding outward, avoid interference of the flexible sealing part 26 during the movement relative to the convex ring 21, and improve the reliability of the movement.

[0055] In one embodiment, the inner wall surface of one end of the flexible sealing portion 26 facing the convex ring 21 is also provided with a guiding inclined surface, so as to further reduce the difficulty of matching the flexible sealing portion 26 with the convex ring 21 .

[0056] In one embodiment, the convex ring 21 extends into the storage cavity 2 , and the interval between the outer wall of the convex ring 21 and the inner wall of the storage cavity 2 is smaller than the thickness of the flexible sealing portion 26 .

[0057] In this embodiment, since the convex ring 21 extends into the storage cavity 2, when the flexible sealing portion 26 is sleeved on the outer periphery of the convex ring 21 and expands outward under the support of the convex ring 21, the portion that passes over the bottom surface of the convex ring 21 will enter into 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 smaller than the thickness of the flexible sealing portion 26. Therefore, the flexible sealing portion 26 entering into the gap will be deformed by the squeezing force of 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 to form a compression seal with the inner wall of the storage cavity 2, thereby achieving a good covering effect.

[0058] In one embodiment, a return spring 29 is disposed between the upper cover 5 and the sealing cover 8 , a first end of the return spring 29 abuts against the bottom wall of the upper cover 5 , and a second end of the return spring 29 abuts against the sealing cover 8 .

[0059] In this embodiment, the second end of the lever 19 is a cantilever structure and has no direct connection with the push cover 18. When the push locking portion 6 is in the unlocked state, the hook body of the hook 11 disengages from the bottom wall of the upper cover 5 along the operating groove 10, contacting the locking effect of the push locking portion 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 downward by the sealing cover 8, and the first end of the lever 19 connected to the connecting rod 20 also moves downward, and the second end of the lever 19 is lifted up, driving the push cover 18 upward, thereby reaching the unlocked position, facilitating the automatic opening operation of the storage box.

[0060] In one embodiment, the sealing cover 8 includes an inner cover 24, a support cover 25 and a flexible sealing portion 26. The inner cover 24 is arranged in the support cover 25 and is detachably connected to the support cover 25. An annular groove 30 is arranged on the outer periphery of the support cover 25. The flexible sealing portion 26 includes an inner ring flange 31, which is clamped in the annular groove 30.

[0061] In this embodiment, the inner cover 24, the support cover 25 and the flexible sealing part 26 adopt a split structure, which can reduce the difficulty of molding each part. In addition, the material selection of the inner cover 24, the support cover 25 and the flexible sealing part 26 is more flexible, which is convenient for selecting suitable materials according to the characteristics of the sealing cover 8 and improving the sealing performance of the sealing cover 8.
