Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and more specifically, to a lock structure and a packaging box. Background Art

[0002] At present, the containers for laundry beads and dishwashing blocks on the market generally include a container body and a cover body. The cover body does not have a lock or child lock structure. When a child touches the container, the cover is easy to open. In order to improve the aesthetics of laundry beads and dishwashing blocks, their designs are usually colorful and very attractive to children. After the child opens the container, the product in the container may be accidentally ingested by the child, causing harm. In order to solve this problem, some containers are provided with a lock structure, but the lock mechanism in the prior art needs to be opened by pressing the buckle with fingers and using the buckle deformation. It is difficult to open the lid, resulting in a poor user experience for consumers. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a locking structure that can solve the problems existing in the traditional packaging structure, improve the protection and ease of use of the product, and enhance the user experience of consumers.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A locking structure is provided, comprising a first annular body and a second annular body which are rotatably engaged with each other through a first clamping part and a second clamping part, wherein a limiting part is provided on the first clamping part, and a notch is provided on the second clamping part so that the first clamping part can be disengaged, and an unlocking part which can be accommodated in the limiting part is also provided in the second clamping part, and the unlocking part is located at a position aligned with the notch; when the first clamping part slides until the limiting part is aligned with the unlocking part, it is in an unlocked state, and the first clamping part can be taken out from the notch to separate the first clamping part from the second clamping part.

[0006] The utility model realizes the functions of convenient and fast locking and unlocking of the first annular body and the second annular body by rotating and buckling the first clamping part and the second clamping part. In the locked state, the first clamping part and the second clamping part can slide relative to each other, but the first clamping part cannot be separated from the second clamping part; in the unlocked state, the first clamping part can be separated from the second clamping part, so as to achieve the separation and unlocking of the first annular body and the second annular body; here, the unlocking part has two functions. The first is that when the limiting part is aligned with the unlocking part, the limiting part can be moved away from the notch, so that the first clamping part is separated from the second clamping part; the second is that when the limiting part is only in contact with the unlocking part and there is no overlap and alignment, the unlocking part plays a limiting role, and the unlocking part is used as the limit of the extreme position of the sliding of the first clamping part and the second clamping part. At this time, a little force is needed to make the limiting part pass over the end of the unlocking part and then move to align with the unlocking part. When the two are aligned, the limiting part is just located directly below or directly above the notch. At this time, the first clamping part can be moved away from the notch from the second clamping part. The purpose of this design is to fix the first ring and the second ring during transportation, and at the same time let consumers feel that the limit part is aligned with the notch, so that they can feel the tactile sensation when unlocking. Since a little force is required to unlock the bag, it can prevent children from accidentally opening and swallowing it. This operation is not difficult for adults, so unlocking is easy, which can improve consumers' user experience.

[0007] Preferably, the first annular body is sleeved on the second annular body, the first clamping portion is protrudingly arranged on the outer wall of the first annular body, and the second clamping portion is concavely arranged on the outer wall of the second annular body.

[0008] Preferably, a locking portion which can abut against the limiting portion for limiting position is further provided in the second clamping portion, and when the first clamping portion slides until the limiting portion abuts against the locking portion, the first clamping portion is in a locked state.

[0009] Preferably, there are at least two first clamping parts and at least two second clamping parts, two or more first clamping parts are evenly arranged on the first annular body, and two or more second clamping parts are evenly arranged on the second annular body; each first clamping part is provided with a corresponding limiting part, and each second clamping part is provided with a corresponding notch and unlocking part.

[0010] Preferably, a guide structure is provided on the top of the unlocking portion.

[0011] Preferably, the notch is located in the middle of the top of the second clamping portion.

[0012] Preferably, a first indicator mark is provided on the first annular body, and a second indicator mark is provided on the second annular body. When the first indicator mark is aligned with the second indicator mark, it is an unlocked state, and the limiting portion is aligned with the unlocking portion.

[0013] Preferably, the first clamping portion and the unlocking portion are both protrusions, the limiting portion is a groove, and the second clamping portion is a sliding groove.

[0014] The utility model also provides a packaging box, comprising a box body and a box cover that are detachably connected; the packaging box is provided with the locking structure as described above, wherein the first annular body is located on the box cover, and the second annular body is located on the box body.

[0015] Preferably, a third indicator mark is provided on the outer side of the box cover, and a fourth indicator mark is provided on the outer side of the box body. When the third indicator mark is aligned with the fourth indicator mark, it is an unlocked state, and the limiting portion is aligned with the unlocking portion.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The rotating buckle mode can facilitate the tightening or opening of the box cover and the box body. The design of the limit part and the unlocking part can serve as an unlocking reminder and prevent children from opening it easily.

[0018] (2) The design of the locking portion adds a layer of security to the lock structure. When the locking portion is aligned with the limiting portion, it is in a locked state. At this time, the first clamping portion and the second clamping portion cannot rotate relative to each other. In the locked state, if the lock needs to be opened, it needs to be twisted twice at different positions. Therefore, the reliability of the lock structure is improved.

[0019] (3) The third indicator mark and the fourth indicator mark are set so that when opening the box cover, the first clamping part of the box cover needs to be rotated to align with the notch of the second clamping part of the box body before unlocking or locking. At the same time, the consumer can feel that the limit part is located at the notch, which is equivalent to not only visually identifying the alignment of the marks to identify the unlocking when unlocking, but also accompanied by tactile perception, which is convenient for consumers to operate and can also prevent children from easily opening the packaging box, thereby avoiding children from accidentally eating, ensuring the safety of children. This is the key to the child lock. The implementation principle is that the intellectual cognition of young children cannot associate the unlocking arrow mark with the position of the limit part, and cannot recognize that the box cover can be pulled up when the arrows are aligned, and cannot open the cover by simply rotating.

[0033] Example 1

[0034] The following is a first embodiment of a lock structure of the utility model. Figure 1 and Figure 2 As shown, it includes a first annular body 1 and a second annular body 2 that are rotatably engaged with a first clamping portion 3 and a second clamping portion 4, a limiting portion 31 is provided on the first clamping portion 3, a notch 41 is provided on the top of the second clamping portion 4 for disengaging the first clamping portion 3, and an unlocking portion 42 that can be accommodated in the limiting portion 31 is further provided in the second clamping portion 4, and the unlocking portion 42 is located below the notch 41; when the first clamping portion 3 slides until the limiting portion 31 is aligned with the unlocking portion 42, it is in an unlocked state, and the first clamping portion 3 can be taken out from the notch 41 to separate the first clamping portion 3 from the second clamping portion 4.

[0035] It is within the knowledge of those skilled in the art that the notch 41 may also be located at the bottom of the second clamping portion 4 , and correspondingly, the unlocking portion 42 is located above the notch 41 .

[0036] As an embodiment of the utility model, the first annular body 1 is sleeved on the outside of the second annular body 2, the first clamping portion 3 is protrudingly arranged on the inner wall of the first annular body 1, and the second clamping portion 4 is concavely arranged on the outer wall of the second annular body 2. Within the scope of knowledge of those skilled in the art, the first clamping portion 3 can also be arranged on the second annular body 2, and correspondingly, the second clamping portion 4 is arranged on the first annular body 1.

[0037] Preferably, the first clamping part 3 and the unlocking part 42 are both protrusions, the limiting part 31 is a groove, and the second clamping part 4 is a slide groove. The first clamping part 3 is inserted into the second clamping part 4 for clamping, and the first clamping part 3 and the second clamping part 4 can be slidably connected. The first clamping part 3 and the second clamping part 4 can slide along the circumferential direction of the first annular body 1 or the second annular body 2, so that the first annular body 1 and the second annular body 2 are movably connected, and the first annular body 1 and the second annular body 2 cannot be separated at will, which is the locked state. At this time, the limiting part 31 is located beside the unlocking part 42; when the limiting part 31 is slightly forced, the locking part 31 is locked. When the positioning portion 31 rotates to overlap and align with the unlocking portion 42 in the radial direction of the first annular body 1 or the second annular body 2, the unlocking portion 42 is just accommodated in the limiting portion 31. At this time, the first clamping portion 3 can be pushed to move upward in a direction perpendicular to the circumferential plane of the first annular body 1 or the second annular body 2, so that the first clamping portion 3 slides out of the notch 41, so that the first clamping portion 3 is disengaged from the second clamping portion 4, and at the same time the first annular body 1 can be separated from the second annular body 2. This is the unlocking state.

[0038] As an embodiment of the present invention, a locking portion 43 which can abut against the limiting portion 31 for limiting position is further provided in the second clamping portion 4. When the first clamping portion 3 slides until the limiting portion 31 abuts against the locking portion 43, the first clamping portion 3 is in a locked state.

[0039] The locking portion 43 is relative to the unlocking portion 42, and the locking portion 43 and the unlocking portion 42 are staggered, and the two are respectively located at the two extreme positions where the first clamping portion 3 slides relative to the second clamping portion 4. When the limiting portion 31 and the locking portion 43 are overlapped and aligned in the radial direction of the first annular body 1 or the second annular body 2, the locking portion 43 clamps and limits the limiting portion 31, so that the second clamping portion 4 cannot slide freely relative to the first clamping portion 3. This is a locked state in the locked state. In the locked state mentioned above, the first clamping portion 3 cannot be disengaged from the second clamping portion 4, but the first clamping portion 3 can slide relative to the second clamping portion 4. In the locked state, the first clamping portion 3 cannot slide relative to the second clamping portion 4, and the two are relatively stationary. This is equivalent to locking the lock structure twice to ensure that children cannot open the lock structure; in the locked state, it is necessary to rotate it with force for the first time to switch to the locked state, and then when the first clamping part 3 slides close to the unlocking part 42, it is necessary to rotate it with force for the second time to switch to the unlocked state. Therefore, it is equivalent to double locking, which increases the difficulty for children to open the lock structure and improves the reliability of the lock structure.

[0040] As an embodiment of the utility model, there are two first clamping parts 3 and two second clamping parts 4, the two first clamping parts 3 are symmetrically arranged on the first annular body 1, and the two second clamping parts 4 are symmetrically arranged on the second annular body 2; each first clamping part 3 is provided with a corresponding limiting part 31, and each second clamping part 4 is provided with a corresponding notch 41 and an unlocking part 42.

[0041] The two first clamping parts 3 are symmetrically distributed along the center of the first annular body 1, and the two second clamping parts 4 are also symmetrically distributed along the center of the second annular body 2, wherein a first clamping part 3, a correspondingly arranged limiting part 31, a second clamping part 4, and an unlocking part 42 form a set of locking structures. In this embodiment, there are two sets of locking structures, which can improve the reliability of locking and enable the first annular body 1 and the second annular body 2 to be subjected to balanced force when locking or unlocking.

[0042] As an embodiment of the present invention, the unlocking portion 42 is provided with a guide structure 421. When the notch 41 is located at the top of the second clamping portion 4, the guide structure 421 is located at the top of the unlocking portion 42; when the notch 41 is located at the bottom of the second clamping portion 4, the guide structure 421 is located at the bottom of the unlocking portion 42. Preferably, the guide structure 421 is a wedge-shaped structure or a pointed structure, which can facilitate the alignment of the limiting portion 31 when inserted from the notch 41 and plugged with the unlocking portion 42, and play a guiding role.

[0043] As an embodiment of the present invention, the notch 41 is located in the middle of the top of the second clamping portion 4. Similarly, if the notch 41 is located at the bottom of the second clamping portion 4, the notch 41 is set in the middle of the bottom of the second clamping portion 4. The setting of the notch 41 can facilitate the insertion or separation of the limiting portion 31 from the second clamping portion 4, and the notch 41 is set in the middle of the second clamping portion 4, which facilitates the locking and unlocking of the first clamping portion 3 and the second clamping portion 4.

[0044] As an embodiment of the utility model, a first indicator mark is provided on the first annular body 1, and a second indicator mark is provided on the second annular body 2. When the first indicator mark is aligned with the second indicator mark, it is an unlocked state, and the limiting portion 31 is aligned with the unlocking portion 42.

[0045] Preferably, the first indicator mark and the second indicator mark can be a triangle symbol, an arrow, or other symbols that can be used for indication; when the first indicator mark and the second indicator mark are aligned, the limit portion 31 is located in the same vertical plane as the notch 41, and the limit portion 31 can enter the unlocking portion 42 from the notch 41, or move from the unlocking portion 42 to the notch 41, thereby facilitating the locking and unlocking of the first clamping portion 3 and the second clamping portion 4. The setting of the indicator mark can serve as a reminder, which is helpful for users to understand the usage and facilitate the locking and unlocking.

[0046] Example 2

[0047] The following is a second embodiment of a locking structure of the utility model. This embodiment is similar to the first embodiment, except that the first clamping portion 3 and the second clamping portion 4 are multiple first clamping portions 3 evenly arranged on the first annular body 1, and multiple second clamping portions 4 evenly arranged on the second annular body 2; each first clamping portion 3 is provided with a corresponding limiting portion 31, and each second clamping portion 4 is provided with a corresponding notch 41 and an unlocking portion 42.

[0048] Similar to the first embodiment, a first clamping part 3, a correspondingly arranged limit part 31, a second clamping part 4, and an unlocking part 42 form a set of locking structures. In this embodiment, preferably, the lock structure has 3 to 5 sets of locking structures; correspondingly, the number of the limit part 31, the second clamping part 4, and the unlocking part 42 is set accordingly. Furthermore, the locking part 43 can also be correspondingly set in each set of locking structures.

[0049] Example 3

[0050] like Figures 3 to 9 The figure shows an embodiment of a packaging box of the utility model, comprising a box body 6 and a box cover 5 that are detachably connected; the packaging box is provided with the above-mentioned locking structure, wherein the first annular body 1 is located on the box cover 5, and the second annular body 2 is located on the box body 6.

[0051] Within the scope of certification of those skilled in the art, the first annular body 1 may also be located on the box body 6, and the second annular body 2 may also be located on the box cover 5. In this embodiment, the packaging box may be in any shape, including but not limited to square, circular, oval, and other regular or irregular shapes. The packaging box of this embodiment may be applied to the packaging of daily necessities such as laundry beads and dishwashing blocks, and may also be applied to the packaging or sealed storage of other products.

[0052] As an embodiment of the utility model, a third indicator mark 7 is provided on the outer side of the box cover 5, and a fourth indicator mark 8 is provided on the outer side of the box body 6. When the third indicator mark 7 is aligned with the fourth indicator mark 8, it is an unlocked state, and the limiting portion 31 is aligned with the unlocking portion 42.

[0053] The third indicator mark 7 and the fourth indicator mark 8 can be triangles, arrows, or other symbols that can be used for indication; when the third indicator mark 7 and the fourth indicator mark 8 are aligned, the limiter 31 is located in the same vertical plane as the notch 41, and the limiter 31 can enter the unlocking part 42 from the notch 41, or move from the unlocking part 42 to the notch 41, thereby facilitating the locking and unlocking of the first clamping part 3 and the second clamping part 4. The setting of the indicator mark can serve as a reminder, which is helpful for users to understand the usage and facilitate the locking and unlocking.

[0054] Specifically, the box body 6 has a concave second clamping part 4, i.e., a sliding groove, on both sides of the front and back of the outer side of the mouth, and the first clamping part 3 can slide in the second clamping part 4 along the circumferential direction; on both sides of the second clamping part 4, there are respectively provided with a raised locking part 43 and an unlocking part 42, and when the front end of the first clamping part 3 contacts the front end of the second clamping part 4, the limiting part 31 is also aligned with the locking part 43, and the box cover 5 cannot continue to rotate clockwise. Similarly, when the rear end of the second clamping part 4 contacts the end of the unlocking part 42, the box cover 5 cannot continue to rotate counterclockwise, thereby playing a limiting role; when the front end of the second clamping part 4 on the box cover 5 contacts the end of the locking part 43, a certain torque needs to be applied to deform the second clamping part 4 to pass through the upper The locking portion 43 makes the limiting portion 31 aligned and snapped with the locking portion 43, thereby playing the role of fixing the position of the box cover 5, at this time the box cover 5 is in a locked state; a notch 41 is provided above the second snap-in portion 4, and the width of the notch 41 is slightly wider than the first snap-in portion 3; the first snap-in portion 3 can pass through the notch 41 to enter the second snap-in portion 4 or escape from the second snap-in portion 4; the unlocking portion 42 is convexly provided below the notch 41, when the first snap-in portion 3 slides along the second snap-in portion 4 to below the notch 41, a certain torque needs to be applied to make the rear end of the first snap-in portion 3 jump over the unlocking portion 42, so that the limiting portion 31 is aligned with the unlocking portion 42, thereby playing the role of fixing the position of the box cover 5, at this time the box cover 5 is in an unlocked state, and the box cover 5 can be separated from the box body 6 by simply pulling it upward.

[0055] When the second clamping part 4 slides to the bottom of the notch 41, the third indicator mark 7 on the box cover 5 is aligned with the fourth indicator mark 8 on the box body 6. Consumers can know that the box cover 5 has reached the open state and can be pulled out by aligning the two indicator marks; when the third indicator mark 7 and the fourth indicator mark 8 are not aligned, that is, the second clamping part 4 is not directly below the notch 41, the box cover 5 cannot be pulled out. Consumers need to identify the opening direction through the mark to achieve the child safety lock function. It takes a little force to cross the end of the unlocking part, mainly to fix the box cover during product transportation, and let consumers feel that the limit part is located below the notch, which is equivalent to tactile perception in addition to seeing the alignment of the mark to identify the unlocking when unlocking. The realization of the child lock is mainly due to the fact that the intellectual cognition of young children cannot associate the unlocking mark with the position of the limit part, and cannot recognize that the box cover can be pulled upwards when the arrows are aligned, and cannot open the box cover by simply rotating.

[0056] As an embodiment of the present utility model, a plurality of evenly arranged reinforcing ribs are further provided in the box cover 5, and a hand-held portion for easy holding is further provided on the box body 6.

[0057] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
