Description

Technical Field

[0001] This application relates to the field of storage devices, and more specifically, to storage boxes. Background Technology

[0002] Most storage boxes on the market currently have a vent valve on the lid, and the lid also has clips on all four sides to connect it to the box body. Therefore, when using the storage box, you often need to first open the vent valve to balance the air pressure inside and outside the box, and then open the clips to open the lid. This process is cumbersome, and to ensure a tight connection between the lid and the box body, the clips are often quite tight, making it difficult to open the lid during use. Utility Model Content

[0003] Therefore, it is necessary to provide a new type of storage box to solve the above problems.

[0009] In some possible implementations, the seal further includes a connecting rod that connects to the rotating member, the sealing portion being sleeved on the connecting rod, and an anti-detachment block provided on the connecting rod, wherein the anti-detachment block protrudes from the connecting rod and is located between the connecting rod and the sealing portion; or, the anti-detachment block is located at the end of the connecting rod away from the rotating member, and the sealing portion is located between the rotating member and the anti-detachment block.

[0010] In some possible implementations, the rotating member may also be detachably provided with a connecting member, the seal being connected to the connecting member, and the connecting member being able to rotate with the rotating member to drive the rotation of the seal connected thereto.

[0011] In some possible implementations, the upper surface of the box cover is provided with a slide rail that cooperates with the locking member, the slide rail is provided with a limiting structure, the locking member is provided with a cooperating structure that cooperates with the limiting structure, the locking member is slidably disposed on the slide rail, and the cooperating structure is slidably disposed on the corresponding limiting structure.

[0012] In some possible implementations, the upper surface of the lid is recessed inward to form a receiving cavity, the through hole is disposed at the bottom of the receiving cavity, and the rotating member is rotatably disposed in the receiving cavity.

[0032] Detailed Implementation

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0034] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] See Figures 1 to 7 This application provides a storage box 100 in some embodiments, including a box body 1, a box lid 2, and a locking mechanism 3. The box lid 2 is detachably connected to the box body 1. The box lid 2 has a through hole T1. The locking mechanism 3 includes a locking component 3a and two locking members 3b. The locking component 3a includes a rotating member 31 and a sealing member 32. The rotating member 31 is rotatably connected to the box lid 2. One end of each locking member 3b is connected to the rotating member 31. The sealing member 32 is connected to the rotating member 31 and is rotatably disposed in the through hole T1. The two locking members 3b are respectively located on both sides of the through hole T1 and are also slidably connected to the box lid 2. The two locking members 3b can slide towards or away from the through hole T1 as the rotating member 31 rotates, so as to lock or unlock the box body 1, while the sealing member 32 also rotates with the rotating member 31 to seal or release the seal of the through hole T1.

[0038] It is understood that the storage box 100 in some embodiments of this application is in its initial state (see...) Figures 1 to 3 The sealing element 32 seals the through hole T1, and the two locking elements 3b lock the box body 1. That is, the storage box 100 is in a sealed state. At this time, if the rotating element 31 is rotated, the sealing element 32 rotates with the rotating element 31 to release the seal on the through hole T1 (that is, to achieve venting). At the same time, the two locking elements 3b will slide away from the through hole T1 due to the rotation of the rotating element 31, so as to disengage from the box body 1 and unlock the box body 1 (see reference). Figures 5 to 7The lid is opened by rotating the rotating component 31. Then, when the rotating component 31 is rotated back to its initial state, the sealing component 32 re-seals the through hole T1 as the rotating component rotates. At the same time, the two locking components 3b slide towards each other relative to the through hole T1 due to the rotation of the rotating component 31, thereby locking the box body 1 and completing the sealing of the storage box 100. This process is repeated to open and lock the storage box 100.

[0039] Therefore, it can be seen that in some embodiments of this application, the storage box 100, with the cooperation of the rotating part 31, the sealing part 32 and the locking part 3b, can simultaneously vent and open or seal and lock the storage box 100 by rotating the rotating part 31 with one click. The operation steps are simple, which greatly improves the efficiency of opening and locking the storage box 100, and greatly reduces the difficulty of opening the lid compared with the traditional opening method, thus improving the user experience.

[0040] In some embodiments, the box body 1 forms a storage space Q1 with an opening K1 on one side, and the box lid 2 closes the opening K1 to seal the storage space Q1. It can be understood that the box body 1 can be as follows: Figure 4 The cuboid shown can also be a regular structure such as a cube, or other irregular structures; no limitation is made here.

[0041] In some embodiments, the box body 1 is further provided with at least one partition 11 for dividing the storage space Q1. The partition 11 is used to divide the storage space Q1 to facilitate the classified storage of items and meet the different storage needs of users. The partition 11 can be fixedly connected to the box body 1 or movably connected to it. Of course, in some other embodiments, the partition 11 can be omitted.

[0042] In some embodiments, each locking member 3b includes a body 34, a linkage part 35, and a locking part 36. The body 34 is slidably connected to the cover 2. The outer surface of the cover 1 is provided with a flange 12 that cooperates with the locking part 36. The linkage part 35 and the locking part 36 are respectively disposed at both ends of the body 34. The linkage part 35 is also connected to a rotating member 31, and can drive the two locking parts 36 to slide towards or away from each other relative to the through hole T1 as the rotating member 31 rotates, so as to connect with the flange 12 to lock or release the connection with the flange 12 to unlock.

[0043] Specifically, the linkage part 35 is located on the side of the body 34 facing the rotating member 31. The locking part 36 includes an extension part 361 and a locking block 362. The extension part 361 extends from the end of the body 34 away from the linkage part 35 toward the lid 2. The locking block 362 protrudes inward from the end of the extension part 361 away from the body 34, and is used to lock the flange 12, thereby locking the lid 2 and the box body 1. It can be understood that due to the connection between the linkage part 35 and the rotating member 31, when the rotating member 31 rotates, it will push the linkage part 35 connected to it to slide toward or away from the through hole T1, thereby driving the locking block 362 to move toward the flange 12 to lock the flange 12 and lock the lid 2 and the box body 1, or to move away from the flange 12 to release the flange 12 and open the lid.

[0044] In some embodiments, each locking member 3b further includes a handle 37. The handle 37 extends from the body 34 in a direction away from the linkage 35. The handle 37 protrudes outward relative to the cover 2 to assist the user in retrieving the storage box 100 when it is at a high / low temperature. Of course, in other embodiments, the handle 37 may be omitted.

[0045] In some implementations, the reference Figures 1 to 8 The rotating part 31 has two sliding grooves C2 on the side facing the box cover 2. The linkage part 35 on each locking part 3b is provided in the corresponding sliding groove C2. When the rotating part 31 rotates, the distance from each point on the motion trajectory formed by the linkage part 35 in the sliding groove C2 to the axis of the rotating part 31 changes from short to long or from long to short. It is understandable that due to the special trajectory design of the slide groove C2, the locking part 3b can slide itself when the rotating part 31 rotates. Specifically, when the distance from each point on the motion trajectory formed by the linkage part 35 in the slide groove C2 to the axis of the rotating part 31 changes from short to long, that is, when the linkage part 35 moves away from the through hole T1 under the drive of the rotating part 31, the locking block 362 on the locking part 36 moves away from the through hole T1 to release the flange 12 and open the lid; when the distance from each point on the motion trajectory formed by the linkage part in the slide groove C2 to the axis of the rotating part 31 changes from long to short, that is, when the linkage part 35 moves towards the through hole T1 under the drive of the rotating part 31, the locking block 362 on the locking part 36 moves towards the through hole T1 to lock the flange 12 and lock the lid 2 and the box body 1.

[0046] In some embodiments, the rotating member 31 has two recessed grooves 314 on the side opposite to the lid 2, serving as finger positions to facilitate user operation of the rotating member 31. Of course, in other embodiments, the grooves 314 may be omitted.

[0047] Furthermore, in some implementations, the reference Figure 4Each locking member 3b also includes a positioning part 38. The body 34 has a groove 341. The positioning part 38 is provided with a sidewall 3411 of the groove 341, and both sides of the positioning part 38 are spaced apart from the sidewall 3411 to form a first limiting gap K2 and a second limiting gap K3. The positioning part 38 includes a first transition surface 381, a second transition surface 382 connected to the first transition surface 381, and a limiting groove C3 formed between the first transition surface 381 and the second transition surface 382. The first transition surface 381 is located between the first limiting gap K2 and the limiting groove C3, and the second transition surface 382 is located between the second limiting gap K3 and the limiting groove C3. The rotating member 31 is provided with a mating part 311 that engages with the positioning part 38. The mating part 311 can slide along the first transition surface 381 and the second transition surface 382 as the rotating member 31 rotates, and can be selectively disposed in the first limiting gap K2, the second limiting gap K3, or the limiting groove C3. The groove 341 formed in the body 34 can be as follows: Figure 4 The through groove shown can also be a blind groove; this is not a limitation here.

[0048] Understandable, participants Figures 1 to 7 In some embodiments of this application, the storage box 100 is initially positioned with the mating part 311 within the limiting groove C3, at which point the storage box 100 is in a sealed state. Next, if the rotating member 31 is rotated towards the first limiting gap K2 or the second limiting gap K3, the mating part 311 slides out of the limiting groove C3 and slides along the first transition surface 381 or the second transition surface 382 until it slides into the first limiting gap K2 or the second limiting gap K3, thereby unlocking the box body 1. Then, if the rotating member 31 is rotated back to the initial state, the mating part 311 slides out of the first limiting gap K2 or the second limiting gap K3 and slides along the first transition surface 381 or the second transition surface 382 until it slides into the limiting groove C3, locking the box body 1 and returning the storage box 100 to a sealed state. Therefore, it can be seen that in some embodiments of this application, the storage box 100, by means of the cooperation between the mating part 311 and the first limiting gap K2, the second limiting gap K3 and the limiting groove C3, limits the rotation stroke of the rotating part 31, so as to help the user clearly understand the rotation angle of the rotating part 31 to open or lock when using the storage box 100, thereby improving the user experience.

[0049] In some implementations, the reference Figure 10The sealing element 32 includes a sealing portion 33 rotatably disposed in the through hole T1. At least one exhaust channel T2 is formed on the surface of the sealing portion 33. A baffle 21 cooperating with the exhaust channel T2 is provided on the side of the cover 2 where the rotating element 31 is located. The baffle 21 is located at the edge of the through hole T1. The rotating element 31 is rotatably connected to the baffle 21. The sealing portion 33 can rotate with the rotating element 31, so that the exhaust channel T2 rotates to the corresponding position of the baffle 21 to seal the through hole T1 together with the baffle 21; or so that the exhaust channel T2 rotates away from the corresponding position of the baffle 21 to allow the exhaust channel T2 to communicate with the internal and external spaces of the box body 1. (This can be understood in conjunction with...) Figures 1 to 7 When the exhaust channel T2 rotates with the sealing part 33 to the corresponding baffle 21 position, the baffle 21 and the sealing part 33 together seal the through hole T1. At this time, the internal space of the box 1 is isolated from the external space, thus achieving the sealing of the storage box 100. When the exhaust channel T2 rotates away from the corresponding baffle 21 position with the sealing part 33, the exhaust channel T2 disengages from the baffle 21 and communicates with the internal and external spaces of the box 1 to achieve exhaust. The internal space of the box 1 is the storage space Q1, and the external space of the box 1 is the space formed by the rotating part 31 and the box cover 2.

[0050] In this embodiment, the structure of the seal 32 differs from that described above. Specifically, refer to... Figure 9 The sealing element 32 further includes at least one venting structure 331 and a sealing strip 332 that mates with the venting structure 331. Both the sealing strip 332 and the venting structure 331 protrude from the outer peripheral surface of the sealing portion 33. Figures 1 to 7 The exhaust structure 331 is connected to the sealing strip 332, and together they are arranged around the outer periphery of the sealing part 33. Each exhaust structure 331 forms an exhaust channel T2. The exhaust structure 331 can rotate with the rotating member 31 to abut or release from the corresponding baffle 21. It can be understood that when the exhaust structure 331 abuts against the corresponding baffle 21, the baffle 21, the sealing strip 332 and the exhaust structure 331 work together to seal the through hole T1, so as to isolate the internal space of the box 1 from the external space and achieve the sealing of the storage box 100; when the exhaust structure 331 releases from the corresponding baffle 21, the exhaust channel T2 is released from the action of the baffle 21 and communicates with the internal space and the external space of the box 1 to achieve exhaust.

[0051] In this embodiment, the seal 32 includes two venting structures 331. Correspondingly, two spaced baffles 21 are provided at the edge of the through hole T1. Of course, in other embodiments, the seal 32 may have only one venting structure 331, or it may be adapted to the specific situation, or it may have three, etc., without further limitation here.

[0052] Furthermore, in some implementations, the reference Figure 11 The sealing element 32 also includes a connecting rod 39. The connecting rod 39 connects to the rotating element 31. The sealing part 33 is sleeved on the connecting rod 39. The connecting rod 39 is provided to facilitate the installation of the sealing part 33. In this embodiment, the anti-detachment block 391 is provided at the end of the connecting rod 39 away from the rotating element 31, and the sealing part 33 is located between the rotating element 31 and the anti-detachment block 391 to prevent the sealing part 33 from slipping out during the rotation of the rotating element 31, thereby achieving anti-detachment.

[0053] It is understood that in some other embodiments, the anti-detachment block 391 protrudes from the surface of the connecting rod 39 and is located between the connecting rod 39 and the sealing part 33 to strengthen the connection between the sealing part 33 and the connecting rod 39 and prevent the sealing part 33 from falling off during the rotation of the rotating member 31.

[0054] Of course, in some other embodiments, the connecting rod 39 may be omitted (e.g. Figure 12 ).

[0055] Furthermore, in some implementations, the reference Figure 8 A connector 313 is detachably provided on the rotating member 31. The sealing member 32 is connected to the connector 313. The connector 313 can rotate with the rotating member 31 to drive the rotation of the sealing member 32 connected thereto. The connector 313 is provided to facilitate the assembly and connection of the sealing member 32.

[0056] Of course, in some other embodiments, connector 313 may be omitted (e.g. Figure 11 and Figure 12 ).

[0057] In some implementations, the reference Figure 3 The end of the baffle 21 away from the lid 2 is provided with a snap-fit ​​structure 21a. The rotating member 31 is provided with a slot structure 312 on the side facing the lid 2, which cooperates with the snap-fit ​​structure 21a. The slot structure 312 is rotatably connected to the snap-fit ​​structure 21a so that the rotating member 31 can rotate relative to the lid 2.

[0058] Of course, in some other embodiments, the slot structure 312 and the buckle structure 21a can be interchanged, that is, the slot structure 312 is disposed on the baffle 21, and the buckle structure 21a is disposed on the rotating member 31.

[0059] In some implementations, the reference Figures 1 to 7 The upper surface 22 of the lid 2 is provided with a slide rail C1 that mates with the locking member 3b. The slide rail C1 is provided with a limiting structure 23, and the locking member 3b is provided with a mating structure C4 that mates with the limiting structure 23. The locking member 3b is slidably disposed on the slide rail C1, and the mating structure C4 is slidably disposed on the corresponding limiting structure 23, so as to prevent the locking member 3b from derailing during sliding.

[0060] In this embodiment, the reference Figure 4 The slide rail C1 is a groove structure, formed by an inward recess from the upper surface 22 of the cover 2. Of course, in some other embodiments, the slide rail can also be a slider structure, formed by a protrusion from the upper surface 22 of the cover 2 (e.g., Figure 13 (As shown).

[0061] In some implementations, the reference Figures 1 to 7 The upper surface 22 of the lid 2 is recessed inward to form a receiving cavity Q2. A through hole T1 is provided at the bottom of the receiving cavity Q2, and the rotating component 31 is rotatably disposed in the receiving cavity Q2. The design of the receiving cavity Q2 not only provides storage space for the rotating component 31, but also indirectly improves the overall aesthetics of the lid 2.

[0062] Of course, in some other embodiments, the receiving cavity Q2 can be omitted (e.g. Figure 13 (As shown).

[0063] In some implementations, the reference Figure 2 The storage box 100 also includes a sealing ring 24. The sealing ring 24 is disposed on the outer periphery of the side of the lid 2 facing away from the rotating member 31, so as to enhance the sealing between the lid 2 and the box body 1 when the lid 2 is closed on the box body 1 and prevent air leakage.

[0064] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
