[0001] The present application relates to the field of storage display devices, in particular to a rotating device and a storage display box. BACKGROUND

[0002] At present, storage display boxes are widely used in daily life and work, which can conveniently store and display various items, including but not limited to dried fruits (such as apricot, raisin, fig, etc.), nuts (such as walnut, cashew, macadamia nut, etc.), cereals (such as oatmeal, wheat germ, cornflakes, etc.) and other healthy foods, as well as tea bags or coffee bags, seasoning bags and other convenient cooking supplies. In addition, storage display boxes are also suitable for storing small stationery (such as paper clips, notepaper, erasers, etc.), seeds (such as flower seeds, vegetable seeds), medicines or health products (such as vitamin tablets, calcium tablets, fish oil, etc.), and jewelry accessories (such as earrings, rings, bracelets, etc.). This multifunctionality makes the storage display box an ideal choice for healthy diet, office work, gardening, personal health care and accessory storage.

[0003] A related art toy packaging box is used for placing a detachable toy, the packaging box comprises a box body and a box cover arranged on the box body, a first fastening part and a second fastening part are arranged between the box body and the box cover, and the box cover and the box body are tightly fastened through the two fastening parts. The box cover is composed of a fixed piece and a rotating piece which are integrally formed, and the two pieces are connected through a fold line, so that the rotating piece can rotate relative to the fixed piece. The fixed piece is provided with a groove and a horizontal piece, and the rotating piece is provided with a boss and a vertical piece, and the stability after rotation is realized through these structures.

[0004] The toy packaging box in the related art is composed of a fixed piece and a rotating piece which are integrally formed, and the two pieces are connected through a fold line. Although the opening and closing of the box cover can be realized, the angle between the box cover and the box body needs to be manually adjusted throughout the process of opening and closing the box cover, so that the user needs to spend more time and effort in the process of opening and closing the box cover. CONTENT OF THE INVENTION

[0005] In order to overcome the problem that the existing storage display box needs to be manually adjusted frequently in the opening and closing process, consumes time and effort, and improve the convenience of use and user experience, the present application provides a rotating device and a storage display box.

[0006] The rotating device and the storage display box provided by the present application adopt the following technical solutions:

[0007] In a first aspect, the application discloses a rotating device, comprising a first connecting piece, a second connecting piece, a driving piece and an elastic reset piece, wherein the first connecting piece is rotationally connected with the second connecting piece; the driving piece moves synchronously with the second connecting piece and abuts against the elastic reset piece to make the elastic reset piece elastically deform; the driving piece comprises a driving arc surface, wherein the driving arc surface is sequentially provided with a first arc surface, a fulcrum and a second arc surface from top to bottom; the elastic reset piece is provided with an abutting point which abuts against the driving arc surface; when the second connecting piece relatively rotates relative to the first connecting piece, the second connecting piece synchronously drives the driving arc surface to rotate, and the first arc surface, the fulcrum and the second arc surface sequentially abut against the abutting point; when the second connecting piece rotates to the position where the fulcrum is away from the abutting point, the elastic restoring force of the elastic reset piece drives the abutting point to move along the first arc surface or the second arc surface, so that the first connecting piece and the second connecting piece continue to relatively rotate without the need of external driving force.

[0008] By adopting the above technical scheme, when the second connecting piece rotates relative to the first connecting piece, the driving arc surface is driven to rotate, and the first arc surface, the fulcrum and the second arc surface sequentially abut against the abutting point. When the second connecting piece rotates to the position where the fulcrum is away from the abutting point, the elastic restoring force of the elastic reset piece drives the abutting point to move along the first arc surface or the second arc surface, so that the first connecting piece and the second connecting piece continue to relatively rotate without the need of external driving force. When the second connecting piece rotates to a first angle range smaller than a critical angle, the cover body can be automatically reset and tightly covered with the box body; when the second connecting piece rotates to a second angle range larger than the critical angle, the fulcrum continuously acts, the driving arc surface is in contact with the elastic reset piece to store elastic potential energy, and the elastic force direction changes to cooperatively act with the opening surface, so that the second connecting piece rotates to a maximum angle position in the opening direction. When the second connecting piece rotates to the position of the fulcrum, the special automatic opening or automatic closing effect is achieved, and if the state is appropriate, the automatic action can be realized by the cooperation of the elastic reset piece and the driving arc surface. The operation of the user to view or take the articles in the box is simplified, the problem that the angle needs to be frequently manually adjusted during the opening and closing process of the existing storage and display box is effectively overcome, the time and energy are saved, and the convenience and user experience are significantly improved.

[0009] Optionally, the first connecting piece comprises a first connecting block and at least two first lugs, the first lugs being fixedly connected or detachably connected with the first connecting block; the second connecting piece comprises a second connecting block and at least two second lugs, the second lugs being fixedly connected or detachably connected with the second connecting block; the rotating device further comprises a rotating shaft, the rotating shaft penetrating through the first lugs and the second lugs in sequence, the first lugs and the second lugs being rotationally connected with the rotating shaft; the driving member is arranged on the second lug, and the driving arc-shaped surface is located at the top corner position of the second lug close to one end of the elastic reset member, so that when the second connecting piece rotates relative to the first connecting piece, the automatic reset or opening function of the first connecting piece and the second connecting piece is realized through the interaction between the driving arc-shaped surface and the abutment point of the elastic reset member. Meanwhile, when the cover body is opened to the maximum angle, the end of the second lug abuts against the surface of the first connecting block under the action of the elastic reset member, the first connecting block blocks the second lug, so that the angle of the cover body remains unchanged, thereby ensuring the stability during rotation.

[0010] By adopting the above technical scheme, the number of the second lugs is multiple, two of which are integrally formed with the two ends of the second connecting block, so as to ensure the stability and reliability of the rotating device during operation. At least one additional second lug is flexibly arranged at the middle position of the second connecting block through detachable connection, so as to facilitate the adjustment of the layout of the lugs according to actual application requirements. The driving member is arranged at the top corner position of each second lug close to the sliding member, and the driving arc-shaped surface thereof precisely abuts against the side wall of the sliding member. During operation of the rotating device, with the rotation of the second connecting piece relative to the first connecting piece, the interaction between the driving arc-shaped surface of the driving member and the side wall of the sliding member can drive the sliding member to smoothly and accurately slide between the first connecting block and the second connecting block.

[0011] Optionally, the second connecting block comprises a turnover surface, the fulcrum of the driving arc-shaped surface being located on a horizontal plane perpendicular to the turnover surface; the first arc-shaped surface is located above the horizontal plane, and the first arc-shaped surface transitions into a second arc-shaped surface downward along the horizontal plane, so that when the second connecting piece rotates relative to the first connecting piece, the driving arc-shaped surface can interact with the abutment point 10 of the elastic reset member according to a predetermined trajectory.

[0012] By adopting the technical scheme, when the second connecting piece rotates relative to the first connecting piece, the driving arc-shaped surface can interact with the abutment point of the elastic reset piece according to a predetermined trajectory. Specifically, as the rotation proceeds, different parts of the driving arc-shaped surface sequentially contact the abutment point, and when the rotation reaches the fulcrum position, due to the special arrangement of the fulcrum and the reasonable transition of the first arc-shaped surface and the second arc-shaped surface, the interaction between the elastic reset piece and the driving arc-shaped surface is more accurate and orderly. The rotating device can realize more stable motion state according to the predetermined trajectory during the rotation process, thereby ensuring that the cover in the application scenarios such as the storage and display box can automatically act in the expected manner during the opening and closing process. Not only the accuracy of the action is improved, but also the convenience and reliability of use are further enhanced, thereby bringing a smoother and more efficient operation experience to the user.

[0013] Optionally, the abutment point when the abutment point and the fulcrum abut is located on the horizontal plane, and the included angle between the abutment point when the abutment point and the first arc-shaped surface or the second arc-shaped surface abut and the horizontal plane is greater than 0 and less than 90°.

[0014] By adopting the technical scheme, when the second connecting piece rotates relative to the first connecting piece, the driving arc-shaped surface can interact with the abutment point of the elastic reset piece according to a predetermined trajectory. Specifically, as the rotation proceeds, different parts of the driving arc-shaped surface sequentially contact the abutment point, and when the rotation reaches the fulcrum position, due to the special arrangement of the fulcrum and the reasonable transition of the first arc-shaped surface and the second arc-shaped surface, the interaction between the elastic reset piece and the driving arc-shaped surface is more accurate and orderly. The rotating device can realize more stable motion state according to the predetermined trajectory during the rotation process, thereby ensuring that the cover in the application scenarios such as the storage and display box can automatically act in the expected manner during the opening and closing process. Not only the accuracy of the action is improved, but also the convenience and reliability of use are further enhanced, thereby bringing a smoother and more efficient operation experience to the user.

[0015] Optionally, the number of the second lugs is multiple, wherein two second lugs are integrally formed at two ends of the second connecting block, and at least one second lug is detachably connected to the middle position of the second connecting block. The driving member is arranged on the multiple second lugs in the middle. The elastic reset piece is an elastic tongue piece, which is arranged on the side of the first connecting block close to the second connecting block. The abutment point is located on the elastic tongue piece.

[0016] By adopting the technical scheme, the number of the second supporting ears is set to be multiple, two of which are integrally formed with the two ends of the second connecting block, thereby ensuring the basic support and stability of the device; and at least one additional second supporting ear is detachably connected to the middle position of the second connecting block, thereby enhancing the adaptability of the device. The driving member is arranged on the second supporting ear located in the middle, and the abutting point thereof accurately acts on the elastic tongue piece, which extends from the first connecting block to the second connecting block and forms an efficient energy storage and release mechanism. During rotation, the interaction between the driving member and the elastic tongue piece not only ensures the smoothness of rotation, but also enables the device to automatically reset or open when reaching a specific position.

[0017] Optionally, a plurality of first mounting grooves are formed in the second connecting block, and the first mounting grooves correspond to the second supporting ears one by one. The outer side wall of the second supporting ear abuts against the inner side wall of the mounting groove, and the second supporting ear is fixedly connected with the second connecting block.

[0018] By adopting the technical scheme, the mounting groove plays a positioning and supporting role on the second supporting ear, effectively preventing the second supporting ear from deviating or shaking during rotation. When the device is running, the second supporting ear can stably rotate around the rotation axis, the driving member drives the driving arc surface to accurately interact with the elastic reset member, thereby ensuring the smooth and reliable automatic action of the display box cover body. At the same time, this fixed connection mode is also convenient for assembly during production and manufacturing, thereby improving the production efficiency.

[0019] Optionally, the number of the second supporting ears is two, and the two second supporting ears are integrally formed with the second connecting block. The driving member is arranged at the top corner position of the second supporting ear close to one end of the elastic reset member. The elastic reset member is located between the first connecting block and the second connecting block, and includes a middle elastic piece and two abutting blocks. The two ends of the middle elastic piece are fixedly connected with the two abutting blocks, respectively. The side wall of the middle elastic piece abuts against the inner side wall of the first connecting block, and the two abutting blocks abut against the two second supporting ears one by one, respectively. The abutting point is located on the abutting block.

[0020] By adopting the technical scheme, only two second lugs integrally formed with the second connecting block are arranged, the basic function of the device is ensured, and complexity and potential failure points caused by too many components are avoided. The driving member is accurately arranged at the top corner position of the second lug close to one end of the elastic reset member, so that the driving member can efficiently interact with the elastic reset member during rotation. The elastic reset member includes an intermediate elastic sheet and two abutting blocks, and the two ends of the intermediate elastic sheet are fixedly connected with the two abutting blocks respectively. The side wall of the intermediate elastic sheet is tightly abutted against the inner side wall of the first connecting block, so as to ensure the stable position of the elastic reset member in the device; and the two abutting blocks are respectively abutted against the two second lugs one by one, so that when the driving member acts on the abutting blocks, more accurate and efficient force transmission effect can be generated. When the device is rotated to a specific position, the driving member abuts against the abutting blocks to trigger the elastic deformation of the elastic reset member, and then the automatic reset or opening function of the device is realized.

[0021] Optionally, the first connecting block is provided with a first positioning block on the side close to the second connecting block, the top of the intermediate elastic sheet is abutted against the lower surface of the first positioning block, and the intermediate elastic sheet is fixedly connected with the first connecting block.

[0022] By adopting the technical scheme, the first positioning block not only provides a more accurate positioning reference for the device, but also enhances the stability of the overall structure. The top of the intermediate elastic sheet is tightly abutted against the lower surface of the first positioning block, so as to ensure the stable position of the intermediate elastic sheet in the device and effectively prevent the deviation or shaking of the intermediate elastic sheet during rotation. Meanwhile, the fixed connection between the intermediate elastic sheet and the first connecting block improves the cooperative working ability between the elastic reset member and the device main body. When the device is rotated, the interaction between the first positioning block and the intermediate elastic sheet provides reliable support and guidance for the elastic reset member, so that the driving member can more accurately and efficiently trigger the elastic deformation when acting on the abutting blocks, and then the automatic reset or opening function of the device is realized.

[0023] Optionally, the elastic reset member includes a sliding member and a first elastic member, the sliding member is located between the first connecting block and the second connecting block, and the sliding member is in sliding cooperation with the first connecting block; the first elastic member is arranged between the sliding member and the first connecting block, one end of the first elastic member is abutted against the side wall of the first connecting block, and the other end of the first elastic member is abutted against the side wall of the sliding member; and the side wall of the driving arc-shaped surface is abutted against the side wall of the sliding member.

[0024] By adopting the above technical scheme, when the second connecting piece rotates relative to the first connecting piece during the operation of the rotating device, the driving piece drives the driving arc surface to move, the driving arc surface pushes the sliding piece to slide on the first connecting block, and at this time, the first elastic piece is compressed to store elastic potential energy. When rotating to a specific position, the driving force of the driving arc surface on the sliding piece is reduced or disappears, the elastic restoring force of the first elastic piece is released to push the sliding piece to slide reversely, and in turn, the driving arc surface continues to move to promote the relative rotation of the first connecting piece and the second connecting piece.

[0025] Optionally, the sliding piece comprises a linkage block, both ends of the linkage block are provided with sliding blocks; each side of the first lug away from the first connecting block is provided with a first sliding groove, the length direction of the first sliding groove is perpendicular to the surface of the first connecting block; the sliding blocks correspond to the first sliding grooves one by one and slide in cooperation; the sliding piece further comprises a third connecting block and a limiting block, the third connecting block is horizontally arranged, one end of the third connecting block is fixedly connected with the linkage block, and the other end of the third connecting block is fixedly connected with the limiting block; the first elastic piece is a spring, one end of the spring abuts against the side wall of the first connecting block, and the other end of the spring abuts against the side wall of the limiting block.

[0026] By adopting the above technical scheme, when the rotating device operates, the driving piece drives the driving arc surface to move, the driving arc surface pushes the linkage block, the linkage block slides in the first sliding groove through the sliding block, and in turn, the whole sliding piece moves, at this time, the spring is compressed to store energy. When the driving force of the driving arc surface changes, the elastic restoring force of the spring is released to push the limiting block, the limiting block drives the linkage block to slide reversely through the third connecting block, so that the sliding piece is reset as a whole and continues to participate in the rotating action. The movement of the sliding piece is more stable and accurate, the elastic effect of the spring can effectively buffer and drive, the reliability and stability of the rotating device are improved, the automatic action of the storage display box cover body is more smooth and accurate, and the overall performance and user experience of the product are improved.

[0027] Optionally, the number of the second lugs is multiple, wherein two second lugs are integrally formed at both ends of the second connecting block, and at least one second lug is detachably connected to the middle position of the second connecting block; each top corner position of the second lug near one end of the sliding piece is provided with a driving piece, and the abutting point is located on the sliding piece.

[0028] By adopting the technical scheme, the number of the second ears is set to multiple, two of which are integrally formed at two ends of the second connecting block, thereby ensuring the basic support and stability of the rotating device; and at least one second ear is detachably connected to a middle position of the second connecting block, thereby providing the possibility of flexibly adjusting the structure of the device according to actual needs. The driving members are arranged at the top corner positions of each second ear close to one end of the sliding member, the driving members accurately act on the abutting positions on the sliding member, and the accuracy and response speed of the movement of the sliding member are further improved.

[0029] In a second aspect, the application further discloses a storage display box, comprising the rotating device described in any one of the preceding aspects, and further comprising a box body and a cover body; a first mounting block is arranged on the first ear of the first connecting member, the box body is fixedly connected with the first mounting block, and the cover body is fixedly connected with the second connecting block of the second connecting member.

[0030] By adopting the technical scheme, in actual use, the driving members of the rotating device drive the driving arc-shaped surface to move and interact with the elastic return member, so that the first connecting member and the second connecting member relatively rotate. Since the box body and the cover body are fixedly connected with the first connecting member and the second connecting member respectively, the relative rotation realizes the automatic opening or closing action of the cover body relative to the box body. The rotating device is ingeniously applied to the storage display box, which not only has a compact and reasonable structure, but also is convenient to operate, and the user does not need to manually and tediously open and close the cover body, thereby improving the convenience and experience of use.

[0031] Optionally, the driving arc-shaped surface of the driving part further comprises a first plane and a second plane, the first plane is parallel to the horizontal plane, and the second plane forms an included angle of less than ° with the horizontal plane; one end of the first plane is smoothly connected to one end of the first arc-shaped surface away from the fulcrum, and one end of the second plane is smoothly connected to one end of the second arc-shaped surface away from the fulcrum; when the second connecting block rotates relative to the first connecting block, the driving arc-shaped surface interacts with the elastic return member to realize the automatic resetting and opening function of the cover body.

[0032] By adopting the technical scheme, when the cover body needs to be opened or reset, different parts of the driving arc-shaped surface are in contact with the elastic return member. Due to the parallel characteristic of the first plane to the horizontal plane, the first plane can provide stable support and moderate resistance at a certain stage, so that the action of the cover body is more stable and controllable; the included angle between the second plane and the horizontal plane can produce varying damping force according to different rotation angles, thereby further adjusting the movement speed and force of the cover body. By utilizing the damping functions of the first plane and the second plane, the deformation and elastic potential energy release of the elastic return member are accurately controlled, the automatic resetting and opening function of the cover body is realized, the accuracy and stability of the action of the cover body are improved, the operation process is more smooth and natural, and the use convenience and user experience of the storage display box are greatly improved.

[0033] Optionally, a locking mechanism is further included, the locking mechanism comprising a first locking component and a second locking component, the first locking component being arranged on the box body, the second locking component being arranged on the cover body, the first locking component and the second locking component being used to lock with each other when the cover body covers the box body, so as to prevent the cover body from being automatically opened.

[0034] By adopting the above technical solution, when the cover body covers the box body, the first locking component and the second locking component are locked with each other, forming a stable connection structure, which effectively prevents the cover body from being automatically opened due to accidents or external forces. Not only the sealing and safety of the storage display box are enhanced, but also the items stored in the box are protected from external interference and damage, and the user's confidence in use is improved. At the same time, when it is necessary to open the cover body, the user only needs to remove the locking state through a specific operation, so as to easily open the cover body, which is convenient to operate and does not affect the normal use of the storage display box.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The rotating device and the storage display box realize the automatic reset and opening of the cover body through the precise cooperation of the unique driving arc surface and the elastic reset member. In the operation process, the user does not need to manually adjust the angle between the cover and the box body frequently, which greatly saves time and effort. Whether it is the automatic reset when closing the cover or the smooth rotation when opening the cover, it brings an unprecedented convenient experience to the user, and significantly improves the comfort and satisfaction of use.

[0037] 2. The addition of the locking mechanism and the sealing ring further enhances the sealing and safety of the storage display box. The mutual locking of the first locking component and the second locking component effectively prevents the cover body from being automatically opened under accidental touch or external force, ensuring the stable storage of the items in the box. At the same time, the tight fit between the cover body and the box body formed by the sealing ring effectively blocks the invasion of impurities such as dust and moisture, protecting the items in the box from being polluted by the external environment, especially suitable for the storage of items with high sealing requirements, such as food and medicine.

[0038] 3. Whether it is the elastic sheet assembly or the cooperative work of the sliding member and the first elastic member, the storage and release efficiency of the elastic potential energy is improved, the friction and wear are reduced, and the service life of the rotating device is prolonged. In addition, the smooth curved surface of the driving arc surface reset surface and the opening surface not only reduces the friction between the elastic reset member, but also makes the cover body more smooth in the opening and closing process, further improving the overall performance of the storage display box and the user experience.

The first connecting piece 1 is connected with the box 6 through the first mounting block 13, thereby providing stable support. The first ear 12 enables the first connecting piece 1 to rotate around the rotating shaft 3. This structure not only ensures the stability of the connection, but also facilitates installation and disassembly.

[0069] The second connecting piece 2 comprises a second connecting block 21, the second connecting block 21 is provided with a second positioning hole 212 and a second bolt hole 213 penetrating through, and the second connecting block 21 is used for connecting the cover body 7. The two ends of the second connecting block 21 are integrally formed with second ears 22, and the two second ears 22 are parallel to each other. The two second ears 22 are located between the two first ears 12, and the outer side wall of each second ear 22 abuts against the inner side wall of the first ear 12. Each end of the rotating shaft 3 penetrates through the second connecting block 21 and the first connecting block 11 in sequence, the first connecting block 11 is rotationally connected with the rotating shaft 3, and the second connecting block 21 is rotationally connected with the rotating shaft 3, so that the first connecting piece 1 and the second connecting piece 2 can relatively rotate.

[0070] In the embodiment, the two second ears 22 are detachably connected with the second connecting block 21, the two second ears 22 are located between the above-mentioned two second ears 22, the four second ears 22 are arranged in the length direction of the rotating shaft 3 and are parallel to each other. Specifically, the bottom of the second connecting block 21 is further provided with two first installation grooves 211, the bottom of each first installation groove 211 is provided in an open manner, and the first installation groove 211 corresponds to the second ear 22 in a one-to-one manner.

In the embodiment, the second connecting piece 2 further comprises a fixing block 24, the fixing block 24 is located on the side of the second connecting block 21 away from the second connecting block, and the two second ears 22 located in the first installation groove 211 are integrally formed with the fixing block 24 at the end close to the fixing block 24.

[0071] Referring to Figure 2 and Figure 3 In the embodiment, the number of the driving pieces 4 is two, and the driving pieces 4 are arranged on the two second ears 22 located in the middle and are integrally formed with the second ears 22. Each driving piece 4 comprises a driving arc surface 41, the driving arc surface 41 is sequentially provided with a first arc surface 411, a fulcrum 412 and a second arc surface 413 from top to bottom; the elastic reset piece is provided with an abutting point 10 abutting against the driving arc surface 41; when the second connecting piece 2 relatively rotates relative to the first connecting piece 1, the second connecting piece 2 synchronously drives the driving arc surface 41 to rotate, and the first arc surface 411, the fulcrum 412 and the second arc surface 413 abut against the abutting point 10 in sequence; when the second connecting piece 2 rotates to the position that the fulcrum 412 is away from the abutting point 10, the elastic restoring force of the elastic reset piece drives the abutting point 10 to move along the first arc surface 411 or the second arc surface 413, so that the first connecting piece 1 and the second connecting piece 2 continue to relatively rotate without the need of external driving force.

[0072] Continuing to refer to Figure 2 andFigure 3 In the embodiment, the first arc surface 411 and the second arc surface 413 are both smooth curved surfaces, including circular arc surfaces, parabolic surfaces, elliptical arc surfaces, polygonal curved surfaces, etc. The friction and wear between the driving arc surface 41 and the elastic return member 5 can be reduced, and the service life of the rotating device can be prolonged. Meanwhile, when the cover 7 is closed to the box 6, the first arc surface 411 contacts the second elastic tongue 512, providing stable support force for the cover 7, ensuring that the cover 7 can be tightly closed on the box 6. Similarly, when the cover 7 is opened to the maximum angle position, the second arc surface 413 contacts the second elastic tongue 512, providing stable support and positioning for the cover 7, preventing the cover 7 from being accidentally closed due to external force. The shape and position of the first arc surface 411 and the second arc surface 413 can also help the driving arc surface 41 to be more accurately positioned during rotation, ensuring that the cover 7 can be smoothly opened or closed, and can be stably stopped at the maximum angle position, facilitating the user to view or take the items in the box.

[0073] Continuing to refer to Figure 2 and Figure 3 , the second connecting block 21 includes a flip surface 23, and the fulcrum 412 of the driving arc surface 41 is located on a horizontal plane 100 perpendicular to the flip surface 23; the first arc surface 411 is located above the horizontal plane 100, and the first arc surface 411 transitions downward along the horizontal plane 100 to form the second arc surface 413. When the second connecting member 2 rotates relative to the first connecting member 1, the driving arc surface 41 can interact with the abutment point 10 of the elastic return member 5 according to a predetermined trajectory.

[0074] Referring to Figure 7 , Figure 8 and Figure 9 , the contact point 200 when the abutment point 10 contacts the fulcrum 412 is located on the horizontal plane 100, and the included angle between the contact point 200 when the abutment point 10 contacts the first arc surface 411 or the second arc surface 413 and the horizontal plane 100 is greater than 0 and less than 90°. So that when rotating to the fulcrum 412 position, the interaction between the elastic return member 5 and the driving arc surface 41 is more accurate and orderly, and the elastic restoring force of the elastic return member 5 can drive the abutment point 10 to move along the first arc surface 411 or the second arc surface 413, thereby enabling the first connecting member 1 and the second connecting member 2 to continue to rotate relative to each other without the need for external driving force.

[0075] In the embodiment, the elastic reset member is an elastic tongue 51, a second mounting groove 111 is formed at the top end of the first connecting block 11, and the elastic tongue 51 is arranged in the second mounting groove 111. The elastic tongue 51 extends from the first connecting block towards the side close to the second connecting block, and the abutment point 10 is located on the elastic tongue 51. Specifically, the elastic tongue 51 includes a first elastic tongue 511 and a second elastic tongue 512, and both the first elastic tongue 511 and the second elastic tongue 512 have elasticity. The bottom end of the first elastic tongue 511 is integrally formed with the first connecting block 11, the top end of the first elastic tongue 511 is integrally formed with the bottom end of the second elastic tongue 512, and both the first elastic tongue 511 and the second elastic tongue 512 are arranged in an inclined manner. The abutment point 10 is located on the side wall of the second elastic tongue 512 close to the driving member 4, and the side wall of the driving arc surface 41 abuts against the side wall of the second elastic tongue 512. The elastic reset member 5 stores and releases elastic potential energy through elastic deformation of the first elastic tongue 511 and the second elastic tongue 512. When the fulcrum 412 of the driving arc surface 41 abuts against the surface of the first elastic tongue 511 and relative rotation occurs, the first elastic tongue 511 can interact with the driving member 4 through elastic deformation of itself, store and release elastic potential energy; during the rotation of the driving member 4, the first elastic tongue 511 cooperates with the driving arc surface 41, and finally the first arc surface 411 or the second arc surface 413 of the driving arc surface 41 abuts against the surface of the first elastic tongue 511, thereby promoting the rotation of the second connecting member 2 relative to the first connecting member 1, and realizing the automatic reset or opening function of the cover 7.

[0076] The implementation principle of the above embodiment is as follows: when the second connecting member rotates relative to the first connecting member to a first angle range (less than a critical angle), the driving arc surface contacts the abutment block 53, and the elastic force generated by the intermediate elastic sheet 52 and the abutment block 53 acts on the driving member, promoting the rotation of the second connecting member relative to the first connecting member towards the closing direction, and realizing the automatic reset of the cover and the tight covering of the box body. When the second connecting member rotates relative to the first connecting member to a second angle range (greater than the critical angle), under the action of the elastic reset member, the driving arc surface continuously interacts with the abutment block 53, stores and releases elastic potential energy, and finally the second connecting member rotates to a maximum angle position (80°-120°). At the same time, when the cover 7 is opened to the maximum angle, under the action of the elastic reset member 5, the end of the second lug 22 abuts against the surface of the first connecting block 11, and the first connecting block 11 blocks the second lug 22, so that the cover 7 cannot be continuously opened, thereby ensuring the stability of the rotation process and facilitating the user to view or take the items in the box. In the whole process, the components work cooperatively, realize the automatic reset and opening function of the cover, and improve the convenience of use and user experience of the storage display box.

[0077] Embodiment 2

[0078] With reference to Figure 7 andFigure 8 The difference between the embodiment 2 and the embodiment 1 is that, in the embodiment 2, the number of the second lugs 22 is two, the two second lugs 22 are respectively located at the two ends of the second connecting block 21, the two second lugs 22 are integrally formed with the second connecting block 21, and the two second lugs 22 are parallel to each other. The number of the driving members 4 is two, the driving members 4 correspond to the second connecting block 21 one by one, the driving members 4 are arranged on the second connecting block 21, and the driving members 4 are integrally formed with the second connecting block 21. In the embodiment 2, the second connecting member 2 does not need to be provided with the detachable second connecting block 21, thereby saving the overall processing cost.

[0079] With reference to Figure 8 The elastic reset member in the embodiment 2 includes the intermediate elastic sheet 52 and the two abutting blocks 53, the two ends of the intermediate elastic sheet 52 are integrally formed with the two abutting blocks 53, and a stable elastic structure is formed. The side wall of the intermediate elastic sheet 52 abuts against the side wall of the first connecting member 1, and the side walls of the two first abutting blocks 53 and the second connecting block 21 abut against the side wall of the driving arc surface 41, thereby providing reliable support for the elastic reset.

[0080] In the embodiment 2, the intermediate elastic sheet 52 includes the intermediate elastic part 521, and the two ends of the intermediate elastic part 521 are provided with the inclined elastic parts 522. One end of each inclined elastic part 522 is integrally formed with the end of the intermediate elastic part 521, and the other end of each inclined elastic part 522 is integrally formed with one end of the fourth elastic sheet. The intermediate elastic part 521 and the two inclined elastic parts 522 are in a sheet shape, the side wall of the intermediate elastic part 521 abuts against the side wall of the first connecting block 11, a complete elastic reset member is formed, and the stability of the elastic reset is ensured. Of course, the intermediate elastic sheet 52 in the embodiment 2 can also be in an integral long strip-shaped sheet structure.

[0081] The top end of the first connecting block 11 is integrally formed with the first positioning block 112, the top of the intermediate elastic part 521 is provided with the second positioning groove 523, the outer side wall of the first positioning block 112 abuts against the inner side wall of the second positioning groove 523, the first positioning block 112 has a positioning effect on the intermediate elastic part 521, and the installation efficiency of the elastic reset member is increased. The side wall of the intermediate elastic part 521 abuts against the side wall of the first connecting block 11, and the intermediate elastic part 521 and the first connecting block 11 are both provided with bolt holes, so that the two can be fixed by bolts.

[0082] The implementation principle of the above embodiment is that when the second connecting piece 2 rotates relative to the first connecting piece 1, the driving arc surface 41 rotates accordingly. When rotated to different angular ranges, the elastic reset piece 5 plays a role. If rotated to a first angular range (less than a critical angle), the driving arc surface 41 is in contact with the abutting block 53, and the elastic force generated by the intermediate elastic sheet 52 and the abutting block 53 acts on the driving piece 4, so as to promote the second connecting piece 2 to rotate relative to the first connecting piece 1 towards the closing direction, thereby realizing the automatic reset of the cover body 7 and the tight covering of the box body 6. When rotated to a second angular range (greater than the critical angle), the driving arc surface 41 and the abutting block 53 continuously interact under the action of the elastic reset piece 5, store and release elastic potential energy, and finally make the second connecting piece 2 rotate to a maximum angular position (80°-120°), so as to facilitate the user to view or take the items in the box. During the whole process, the components work cooperatively to realize the automatic reset and opening function of the cover body 7, and improve the convenience of use and user experience of the storage display box.

[0083] Embodiment 3

[0084] With reference to Figure 9 and Figure 10 , the second connecting piece 2 in this embodiment is the same as that in embodiment 1. Embodiment 3 is different from embodiment 1 in that the number of driving pieces in this embodiment is four, and each second supporting lug 22 is provided with a driving piece. The side walls of the driving arc surfaces 41 of the four driving pieces 4 simultaneously abut against the side walls of the sliding piece 54, thereby realizing the stable reset function of the rotating device.

[0085] The elastic reset piece in this embodiment includes the sliding piece 54 and the first elastic piece 55. The sliding piece 54 is located between the first connecting piece 1 and the second connecting piece 2, and the sliding piece 54 is in sliding cooperation with the first connecting piece 1. The first elastic piece 55 is arranged between the sliding piece 54 and the first connecting piece 1, one end of the first elastic piece 55 abuts against the side wall of the first connecting piece 1, and the other end of the first elastic piece 55 abuts against the side wall of the sliding piece 54.

[0086] With reference to Figure 10 and Figure 11 , specifically, the sliding piece 54 includes the linkage block 541, and the linkage block 541 is integrally formed with two sliding blocks 542 on the side away from the first connecting block 11. Each first supporting lug 12 is provided with a first sliding slot 121 on the side away from the first connecting block 11. The length direction of the first sliding slot 121 is perpendicular to the surface of the first connecting block 11, and the end of the first sliding slot 121 away from the first connecting block 11 is in an open arrangement. The sliding block 542 corresponds to the first sliding slot 121 in a one-to-one manner, and the sliding block 542 is in sliding cooperation with the first sliding slot 121.

[0087] The sliding piece 54 further comprises a third connecting block 543 and a limiting block 544. The third connecting block 543 is horizontally arranged, and one end of the third connecting block 543 is fixedly connected to the side wall of the linkage block 541, and the other end of the third connecting block 543 is fixedly connected to the limiting block 544. In this embodiment, the first elastic member 55 is specifically a spring, and the number of the spring is two. The two springs are both arranged in a horizontal direction, one end of each spring is abutted against the inner side wall of the limiting block 544, and the other end of each spring is abutted against the inner side wall of the first connecting block 11. Meanwhile, the side of the limiting block 544 close to the spring is further provided with two limiting columns 545, and the end of each spring is sleeved on the limiting column 545. When the sliding block 542 slides in the first sliding slot 121, the spring is compressed or stretched, and stores or releases elastic potential energy. When the external force disappears, the spring releases the stored elastic potential energy, drives the sliding piece 54 and the driving arc surface 41 to move reversely, and the reset of the rotating device is realized.

[0088] The implementation principle of the above embodiment is as follows: when the second connecting member 2 rotates relative to the first connecting member 1, the driving arc surface 41 rotates accordingly. In the rotating process, the side wall of the driving arc surface 41 abuts against the side wall of the sliding piece 54, and drives the sliding piece 54 to slide in the first sliding slot 121. Since the sliding piece 54 is in sliding cooperation with the first connecting member 1, and the first elastic member 55 is arranged between the sliding piece 54 and the first connecting member 1, when the sliding piece 54 slides, the first elastic member 55 is compressed or stretched, thereby storing or releasing elastic potential energy. When rotating to different angle ranges, the elastic reset member plays a role. When rotating to a first angle range (less than a critical angle), under the action of the elastic force of the first elastic member 55, the second connecting member 2 is driven to rotate relative to the first connecting member 1 towards the closing direction, thereby realizing the automatic reset of the cover body 7 and the tight covering of the box body 6. When rotating to a second angle range (greater than the critical angle), under the action of the first elastic member 55, the driving arc surface 41 and the sliding piece 54 continuously interact, the elastic potential energy is stored and released, and finally the second connecting member 2 is rotated to a maximum angle position (80°-120°), thereby facilitating the user to view or take the items in the box. In the whole process, the components work cooperatively, the automatic reset and opening function of the cover body 7 is realized, and the convenience of using the storage display box and the user experience are improved.

[0089] Embodiment 4

[0090] With reference to Figure 9 and Figure 11 , the present embodiment discloses a storage display box, which comprises the rotating device of the above-mentioned embodiments 1-3, and further comprises a box body 6 and a cover body 7. The box body 6 is connected with the first connecting member 1, and the cover body 7 is connected with the second connecting member 2, thereby realizing the rotating connection function between the cover body 7 and the box body 6.

[0091] With reference toFigure 10 and Figure 12 The first avoiding slot 61 is located between the two first positioning slots 62, the first avoiding slot 61 is in communication with the two first positioning slots 62, and the depth of the first avoiding slot 61 is greater than the depth of the two first positioning slots 62. The first avoiding slot 61 is used for accommodating the elastic reset member 5, and at the same time ensures that the elastic reset member 5 does not interfere with the box body 6 during movement. The first positioning slot 62 corresponds to the first mounting block 13 one by one, and the outer side wall of each first mounting block 13 abuts against the inner side wall of the first positioning slot 62. The bottom of each first positioning slot 62 is integrally formed with a first positioning column 63, and a first positioning hole 131 is formed in each mounting block. Each first positioning column 63 is arranged in the first positioning hole 131, thereby achieving stable positioning. At the same time, a bolt is arranged in the first bolt hole 132, thereby facilitating the fixation of the first connecting piece 1 to the box body 6.

The second connecting block 21 is fixed in the third positioning slot 72, the outer side wall of the second connecting block 21 abuts against the inner side wall of the third positioning slot 72, and the second positioning column 73 is arranged in the second positioning hole 212, thereby facilitating the fixation of the second connecting piece 2 to the cover body 7.

[0093] Referring to Figure 3 The driving arc surface 41 further includes a first plane 414 and a second plane 415. One end of the first plane 414 is smoothly connected to one end of the first arc surface 411 away from the fulcrum 412, and one end of the second plane 415 is smoothly connected to one end of the second arc surface 413 away from the fulcrum 412. In this way, when the second connecting piece 2 rotates relative to the first connecting piece 1, the driving arc surface 41 can smoothly interact with the elastic reset member, thereby achieving the automatic reset and opening functions of the cover body 7. During rotation, the first plane 414 and the second plane 415 can contact the elastic reset member in a stable and controllable manner due to their damping characteristics. They will not cause loose contact with the elastic reset member due to an excessively large included angle, and will not cause excessive friction or interference due to an excessively small included angle, thereby affecting the normal operation of the storage display box.

[0094] Referring to Figure 11 and Figure 14 The locking mechanism 8 includes a first locking assembly 81 and a second locking assembly 82. The first locking assembly 81 is arranged on the box body 6, and the second locking assembly 82 is arranged on the cover body 7.

[0095] Reference Figure 14 The first locking assembly 81 includes a sliding seat 811 and a second elastic member 812. The sliding seat 811 includes a pressing member 8111, a first locking member 8112, and a first anti-detachment block 8113. The pressing member 8111 and the first locking member 8112 are integrally formed. The first anti-detachment block 8113 is integrally formed on the side wall of the first locking member 8112. The top end of the first anti-detachment block 8113 is flush with the top end of the first locking member 8112. There is a gap between the first anti-detachment block 8113 and the bottom of the top groove 8114.

[0096] The top of the box body 6, on the side away from the rotating device, has a second sliding groove 64 and an anti-detachment groove 65 that are interconnected. Both the tops of the second sliding groove 64 and the anti-detachment groove 65 are open. The anti-detachment groove 65 is a square groove, and the second sliding groove 64 is a T-shaped groove; together, they form an "I"-shaped groove. The first locking member 8112 is located within the anti-detachment groove 65, and the first locking member 8112 slides in engagement with the anti-detachment groove 65. The pressing member 8111 is located within the second sliding groove 64, and the pressing member 8111 slides in engagement with the second sliding groove 64.

[0097] Continue to refer to Figure 14 In this embodiment, there are two second elastic elements 812, both located between the sliding member 54 and the second sliding groove 64. One end of the second elastic element 812 abuts against the side wall of the second sliding groove 64, and the other end abuts against the side wall of the pressing member 8111. In this embodiment, the second elastic element 812 is specifically in the form of a spring, and the side wall of the second sliding groove 64 is also provided with a third positioning hole 122 corresponding to the spring. The side of the spring near the housing 6 is placed inside the third positioning hole 122.

[0098] Reference Figure 14 and Figure 15The upper surface of the sliding seat 811 is provided with a top groove 8114 for inserting the second locking assembly 82, and the top groove 8114 is located between the pressing piece 8111 and the first locking piece 8112. The first locking piece 8112 is integrally formed with a first anti-disengagement block near the side wall of the top groove 8114, and there is a space between the first anti-disengagement block and the groove bottom of the top groove 8114 for accommodating the second locking assembly 82. The second locking assembly 82 includes a fixing piece 821, a second locking piece 822, and a second anti-disengagement block 823, the fixing piece 821 and the second locking piece 822 are integrally formed and combined to form an L shape, and the second anti-disengagement block 823 is integrally formed on the side wall of the second locking piece 822, wherein the fixing piece 821 is fixed to the side of the cover body 7 facing the box body 6 by a bolt. When the cover body 7 is in the closed state, the side wall of the first locking piece 8112 abuts against the side wall of the second locking piece 822, and at the same time, the lower surface of the first anti-disengagement block 8113 also abuts against the upper surface of the second anti-disengagement block 823, thereby effectively preventing the cover body 7 from being automatically opened. In addition, the end of the second anti-disengagement block 823 is also provided with a chamfer, which makes the process of closing the cover body 7 more smooth.

[0099] The cover body 7 is provided with a ring-shaped piece 71, and a ring-shaped groove 67 is formed on the outer side wall of the ring-shaped piece 71 or the inner side wall of the box body 6, and a sealing ring 9 is installed in the ring-shaped groove 67. The ring-shaped groove 67 ensures that the sealing ring 9 can be correctly installed at the predetermined position and play its sealing role. The sealing ring 9 is usually made of elastic material, such as rubber or silicone. When the cover body 7 is closed, the sealing ring 9 can fill the small gap between the cover body 7 and the box body 6, thereby increasing the overall sealing performance of the storage and display box.

[0100] Referring to Figure 11 and Figure 14 Meanwhile, the top of the box body 6 is also provided with a fourth positioning groove 66, and a shielding block 83 is fixedly arranged in the fourth positioning groove 66. The shielding block 83 can prevent dust and the like from entering the inside of the anti-disengagement groove 65 and the first sliding groove 121, thereby increasing the overall neatness of the box body 6. Meanwhile, the shielding block 83 is provided with a through hole 84 for the second locking piece 822 and the second anti-disengagement block 823 to pass through.

[0101] The implementation principle of the embodiment is as follows: when rotated to a first angle range (less than a critical angle), the driving arc-shaped surface 41 contacts the sliding piece 54, and the elastic force generated by the elastic reset piece 5 acts on the driving piece 4, thereby promoting the second connecting piece 2 to rotate relative to the first connecting piece 1 towards the closing direction, so as to realize the automatic reset of the cover body 7 and the tight closing of the box body 6. When rotated to a second angle range (greater than the critical angle), the driving arc-shaped surface 41 continuously interacts with the elastic reset piece 5 under the action of the elastic reset piece 5, so as to store and release the elastic potential energy, and finally make the second connecting piece 2 rotate to a maximum angle position (80°-120°), thereby facilitating the user to view or take the items in the box.

[0102] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
