[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0045] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0046] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0048] The packaging box is used to package the product to prevent the product from being damaged in case of falling during transportation.

[0049] Some packaged products have different lengths, for example, camera devices in electronic products have different lengths. However, in the prior art packaging boxes, the depth of the storage cavity is unique. If it is necessary to package products of different lengths, a box body with a suitable size should be selected to match the size of the corresponding packaged product. However, this will result in too many types of packaging boxes, which is not conducive to the standardization of packaging box sizes.

[0050] While some packaging boxes can move the supporting plate for supporting the packaged products so as to adapt to most packaged products of different lengths and sizes through one specification of packaging box, a connecting block is connected to the supporting plate by rotating through a rotating shaft, and a lifting groove is formed on the side wall of the storage cavity, and a plurality of latching protrusions are formed on the groove wall surface of the lifting groove and are arranged at intervals along the depth direction of the storage cavity, and a latching groove is formed by two adjacent latching protrusions, so that the supporting plate can rotate the connecting block during the movement to be inserted into different latching grooves to achieve the height stop of the supporting plate. However, in this manner, the supporting plate needs to have a connecting block and a rotating shaft to cooperate, the structure is complex, the number is large, and the rotating shaft is easily damaged after long-term use, so that the service life of the packaging box is short.

[0051] To solve the above problems, please refer to Figure 1 The present application proposes a packaging box 100. In the embodiments of the present application, please refer to Figures 2 to 4 The packaging box 100 may include a box body 10, a supporting plate 30 and a buffer member 50. The box body 10 forms a storage cavity 10a. The supporting plate 30 and the buffer member 50 are respectively accommodated in the storage cavity 10a. The supporting plate 30 is used to support the packaged product (for example, it can be an electronic product, such as a camera device or a mobile phone, etc., or it can be food or beverages, etc.), and can move along the depth direction of the storage cavity 10a.

[0052] The box body 10 is cylindrical, rectangular or multi-prism shaped, etc. The main structure of the box body 10 can be a paper box, which has the advantages of strong plasticity, low cost and light weight to reduce transportation costs, etc. It can be understood that strong plasticity means that the paperboard can adjust its own structure according to the shape of the packaged product to match the packaged products of different shapes. Of course, the main structure of the box body 10 can also be a metal box, which has the advantage of better strength, and this application does not limit this.

[0053] The box body 10 may include a sky box 11 and a ground box 13. The sky box 11 and the ground box 13 may both be cylindrical, rectangular or multi-prism shaped, and the shapes of the two may match. The sky box 11 and the ground box 13 may both be paper boxes, or one may be a paper box and the other may be a metal box, which is not limited in the present application. The sky box 11 may be sleeved in a paper box, and cooperate with the ground box 13 to enclose a storage cavity 10a. It can be understood that the inner surface of the sky box 11 facing the ground box 13 constitutes the top wall of the storage cavity 10a, the inner side wall of the ground box 13 constitutes the side wall of the storage cavity 10a, and the inner surface of the ground box 13 facing the sky box 11 constitutes the bottom wall of the storage cavity 10a. Of course, the sky box 11 and the paper box may also be in the form of two symmetrical half boxes, which are spliced ​​to form the box body 10, which is not limited in the present application.

[0054] When the sky box 11 is configured to be sleeved on a paper box, an open mounting groove may be formed in the sky box 11, and the ground box 13 is inserted into the opening and has an interference fit with the mounting groove, so that the user can pull the sky box 11 out from a direction away from the ground box 13, or pull the ground box 13 out from a direction away from the sky box 11, which is easy to operate. In other connection forms, when the ground box 13 is a metal box, the inner wall of the sky box 11 may be provided with a magnetic suction member, so that the sky box 11 can be sleeved on the paper box through the magnetic suction cooperation between the magnetic suction member and the metal box, and the present application does not limit this. In this way, when the user takes out the packaged product from the storage cavity 10a, or places the packaged product into the storage cavity 10a, the operation is convenient, and the packaging box 100 can be used multiple times, and the reusability is higher.

[0055] It can be understood that when the box body 10 is configured as a two-part structure of the sky box 11 and the ground box 13, it has the advantages of easy disassembly and assembly and high reusability. Of course, the box body 10 of the present application can also be configured as a single cylindrical structure as a whole, that is, the sky box 11 and the ground box 13 are in an integral form, an opening is formed through the top of the box body 10, and the opening is sealed by inserting the tongue of the box body 10, so that the manufacturing process can be simplified. The following content is still in the form of the box body 10 configured as a sky box 11 and a ground box 13, and further explains the situation that the packaging box 100 of the present application can adapt to packaged products of different sizes.

[0056] The support plate 30 includes a plate body 31. The plate body 31 may be circular, square or irregular in shape, and the shape of the plate body 31 may be adapted to the cross-sectional shape of the storage cavity 10a. For example, when the top box 11 and the bottom box 13 of the box body 10 are both cylindrical, the cross-sectional shape of the storage cavity 10a is circular, so the shape of the plate body 31 may be circular to adapt to the cross-sectional shape of the storage cavity 10a. The plate body 31 may be cardboard, which has the advantages of low cost and light weight to reduce transportation costs, etc. Of course, the plate body 31 may also be a metal plate to have good anti-deformation ability, so that when supporting electronic equipment, the possibility of deformation of the support plate 30 due to excessive weight of the electronic equipment is reduced.

[0057] The buffer 50 may be a structural component with buffering properties, such as a compression spring 51 or a sponge or other elastic structure, which is not limited in the present application, and is connected between the cavity bottom wall of the storage cavity 10a and the plate body 31. In the actual transportation process, when the packaged product is a product that is relatively expensive and easily damaged when falling, it is necessary to provide buffering protection for the packaged product. Therefore, the buffer 50 of the packaging box 100 of the present application is connected between the cavity bottom wall of the storage cavity 10a and the plate body 31. When the packaging box 100 falls during transportation, the packaged product will have a tendency to fall downward. Under the setting of the buffer 50, a buffering effect can be provided for the packaged product to prevent the packaged product from falling directly and coming into hard contact with the cavity bottom wall of the accommodating cavity to be damaged.

[0058] In order to enable the storage cavity 10a to accommodate packaged products of different sizes, the structure of the support plate 30 of the present application and the matching form with the storage cavity 10a may include but are not limited to the following two forms:

[0059] For the first form, please refer to Figures 3 to 5 , a guide groove 15 and a plurality of snap-in grooves 17 are formed on the side wall of the storage cavity 10a, that is, the guide groove 15 and the snap-in groove 17 may be formed by recessing the side wall of the storage cavity 10a. The guide groove 15 extends along the depth direction of the storage cavity 10a, and a plurality of snap-in grooves 17 are connected to the guide groove 15 and are arranged at intervals along the extension direction of the guide groove 15. The support plate 30 further includes a card block 33, and the card block 33 is connected to the plate body 31. For example, the card block 33 may be directly connected to the outer edge of the plate body 31. Specifically, the card block 33 and the plate body 31 may be an integral structure, so that the connection between the two is more fixed and the assembly steps are reduced. Of course, the card block 33 and the plate body 31 may also be a split structure, for example, fixed by bonding or snap-in, etc., and the present application does not limit this.

[0060] The block 33 is configured to be slidably disposed in the guide groove 15, and when the plate body 31 is connected to the block 33, the plate body 31 can move along the depth direction of the storage cavity 10a. Under the action of external force, such as the force applied by the user's hand, the plate body 31 will rotate relative to the box body 10, so that the block 33 is selectively inserted into one of the multiple engaging grooves 17, and the plate body 31 stays at the height position where the engaging groove 17 connected to the block 33 is located.

[0061] Specifically, when the box body 10 is cylindrical, the projection of the clamping groove 17 in the radial direction of the box body 10 is outside the projection range of the guide groove 15, and each clamping groove 17 can extend along the circumference of the box body 10 on the basis of being connected to the guide groove 15, so that when the plate body 31 rotates, the clamping block 33 can be clamped into the clamping groove 17 extending along the circumference of the box body 10. In addition, the present application does not specifically limit the number of clamping grooves 17, and the number of clamping grooves 17 can be selected according to the number of height positions where the actual plate body 31 needs to stay, for example, it can be two, three or four, etc.

[0062] The side wall of the storage cavity 10a is configured to form a guide groove 15 and a plurality of snap-in grooves 17, and the guide groove 15 and the plurality of snap-in grooves 17 are combined to form a connection module. There are two groups of connection modules, and there are two clamping blocks 33, and the two clamping blocks 33 are symmetrically distributed in the circumferential direction of the plate body 31, wherein the two clamping blocks 33 correspond to the two groups of connection modules one by one. In this way, through the corresponding cooperation between the two clamping blocks 33 and the two groups of connection modules, the stability of the plate body 31 when it stays at the required height position and is placed in the storage cavity 10a can be improved, and the stability of the packaged product supported by the plate body 31 can be improved.

[0063] For further information, please refer to Figures 5 to 7 The clamping groove 17 includes a first sub-groove 17a and a second sub-groove 17b. In the circumferential direction of the box body 10, the first sub-groove 17a and the second sub-groove 17b are respectively arranged on opposite sides of the guide groove 15, and the first sub-groove 17a and the second sub-groove 17b extend along the circumferential direction of the box body 10, and the two extend in opposite directions. The clamping block 33 selectively clamps into the first sub-groove 17a or the second sub-groove 17b of one of the clamping grooves 17. In this way, in the actual rotation process, when the user applies external force to drive the plate body 31 of the supporting plate 30 to rotate, whether it is rotated clockwise or counterclockwise, the clamping block 33 can be clamped into the second sub-groove 17b or the first sub-groove 17a of the clamping groove 17. Under such a setting, the user does not need to spend attention, experience and professional knowledge to directly and correctly complete the correct operation of the clamping block 33 being able to be clamped into the clamping groove 17, which is convenient for the user to operate and can improve the user's use experience.

[0064] In order to prevent the block 33 from being disengaged from the first sub-slot 17a or the second sub-slot 17b of the engaging slot 17 due to excessive bumps during transportation, please continue to refer to Figure 6The first sub-groove 17a and the second sub-groove 17b of the clamping groove 17 of the present application may include a first groove section 17c, a second groove section 17d and a third groove section 17e which are connected in sequence. The first groove section 17c is connected to the guide groove 15, and is arranged with the third groove section 17e in the depth direction of the storage cavity 10a, and both extend along the circumference of the box body 10, and the second groove section 17d extends along the depth direction of the storage cavity 10a. The clamping block 33 may pass through the first groove section 17c and the second groove section 17d in sequence and then be clamped into the third groove section 17e. Under such a configuration, the block 33 will eventually be fixedly inserted into the third slot section 17e. It is understandable that if the block 33 is to be disengaged from the third slot section 17e, the packaging box 100 needs to be tilted in the direction opposite to the extension direction of the third slot section 17e. If the block 33 is to be disengaged from the first slot section 17c, the packaging box 100 needs to be tilted in the direction opposite to the extension direction of the first slot section 17c. The extension direction of the first slot section 17c is opposite to the extension direction of the third slot section 17e. The packaging box 100 needs to be tilted in at least two opposite directions to cause the block 33 to be disengaged from the first sub-slot 17a or the second sub-slot 17b of the clamping slot 17. In this way, the possibility of the block 33 being disengaged from the first sub-slot 17a or the second sub-slot 17b of the clamping slot 17 can be reduced, thereby preventing the support plate 30 from being offset during transportation, and further preventing the packaged product from falling and causing damage.

[0065] For the second form, please refer to Figures 8 to 9 A guide rail 18 is provided on the side wall of the storage cavity 10a, and the guide rail 18 extends along the depth direction of the storage cavity 10a. It can be understood that the guide rail 18 is protruding from the side wall of the storage cavity 10a, and the guide rail 18 can be connected to the side wall of the storage cavity 10a by threaded connection, snap connection or bonding. The guide rail 18 is formed with a plurality of limit fixing grooves 19 arranged at intervals in the extension direction thereof.

[0066] The plate body 31 is provided with a limiting notch 31b for the guide rail 18 to pass through, and is slidably provided on the guide rail 18, so that the plate body 31 can move along the depth direction of the storage cavity 10a by the limiting notch 31b avoiding the guide rail 18. Under the action of external force, such as the force applied by the user's hand, the plate body 31 rotates relative to the box body 10, so that the portion of the plate body 31 other than the limiting notch 31b is selectively fixed to one of the plurality of limiting fixing grooves 19, and the plate body 31 stays at the height position where the limiting fixing groove 19 connected thereto is located. Specifically, when the board body 31 moves to the height position where it is required to stay, the limit notch 31b of the board body 31 corresponds to the limit fixing groove 19 corresponding to the height position. At this time, the user can apply force to realize the rotation of the board body 31, so that the part of the board body 31 other than the limit notch 31b is fixed in the limit fixing groove 19. In this form, no matter whether the user rotates clockwise or counterclockwise, the part of the board body 31 other than the limit notch 31b can cooperate with the limit fixing groove 19.

[0067] The side wall of the storage cavity 10a is configured to be provided with guide rails 18, the number of the guide rails 18 is two, the number of the limiting notches 31b is two, and the two limiting notches 31b are symmetrically distributed in the circumferential direction of the plate body 31, wherein the two limiting notches 31b correspond one to one with the two guide rails 18. In this way, through the corresponding cooperation between the two limiting notches 31b and the two guide rails 18, the stability of the plate body 31 when it stays at a desired height position and is placed in the storage cavity 10a can be improved, and the stability of the packaged product supported by the plate body 31 can be improved.

[0068] The technical solution of the present application is that under the action of external force, the plate body 31 can be rotated relative to the box body 10, so that the block 33 connected to the plate body 31 can be selectively inserted into one of the multiple clamping grooves 17, or the part of the plate body 31 other than the limited notch 31b can be selectively inserted into one of the multiple limited fixing grooves 19. In this way, the plate body 31 can be adapted to stay at different height positions according to the packaged products of different sizes, so that the packaged products can be placed in the storage cavity 10a of the box body 10 under the support of the plate body 31, thereby eliminating the need to produce box bodies 10 of different sizes to match with packaged products of different sizes, which is conducive to the size standardization of the packaging box 100. Compared with the existing packaging box whose support plate cannot be adjusted in height, the support plate 30 of the packaging box 100 of the present application can be adjusted in height, which is more operable and can provide users with a better usage experience.

[0069] In addition, the supporting plate 30 of the packaging box 100 of the present application, whether it is a block 33 fixedly connected to the plate body 31, which is matched with the snap-in groove 17 by rotating the plate body 31, or a notch is opened in the plate body 31, and the plate body 31 is matched with the limiting fixing groove 19 by rotating the plate body 31, the supporting plate 30 does not need to be provided with additional components to achieve the matching with the snap-in groove 17 or the limiting fixing groove 19. In this way, the structure of the packaging box 100 of the present application is simpler and the number of structures is smaller. While reducing the assembly steps, it can also reduce the weight of the packaging box 100, which is more suitable for transportation scenarios.

[0070] The above content introduces the advantages of the packaging box 100 of the present application that it can adapt to packaged products of different sizes from two specific matching forms of the support plate 30 and the storage cavity 10a of the box body 10. On this basis, please refer to Figures 2 to 4 In order to further improve the stability of the support plate 30 staying in the storage cavity 10a, the buffer member 50 of the present application can be configured as a compression spring 51, one end of the compression spring 51 abuts against the bottom wall of the storage cavity 10a, and the other end abuts against the surface of the plate body 31 facing the compression spring 51.

[0071] It is understandable that the connection between the compression spring 51 and the bottom wall of the storage cavity 10a can be in the form of bonding or nailing, etc., and the present application does not limit this. Under the setting of the buffer 50, the compression spring 51 can give the plate body 31 an upward elastic force (that is, in the depth direction of the storage cavity 10a, the compression spring 51 gives the plate body 31 an elastic force in the direction away from the bottom wall of the storage cavity 10a). Under such arrangement, in the first matching form, when the block 33 is inserted into the first sub-groove 17a or the second sub-groove 17b, the block 33 will press against the groove wall of the first sub-groove 17a or the second sub-groove 17b under the drive of the compression spring 51, so that even if the packaging box 100 falls and tilts, the probability of the block 33 being separated from the clamping groove 17 will be greatly reduced; and in the second matching form, when the part other than the limiting notch 31b of the plate body 31 is fixed to the limiting fixing groove 19, the plate body 31 will press against the groove wall of the limiting fixing groove 19 under the drive of the compression spring 51, so that even if the packaging box 100 falls and tilts, the probability of the plate body 31 being separated from the limiting fixing groove 19 will be greatly reduced.

[0072] At the same time, in actual operation, when the height position of the board body 31 needs to be adjusted, especially when the board body 31 needs to be raised, when the block 33 is disengaged from the card slot 17, or the board body 31 is disengaged from the limit fixing slot 19, the compression spring 51 will also give the board body 31 an upward elastic force, so that the board body 31 can have an upward trend, which is more convenient for users to operate.

[0073] In order to make the packaged product more stable when placed in the storage cavity 10a, the plate body 31 of the present application forms a limit groove 35a with an open opening on one side facing the compression spring 51, and the central axis of the limit groove 35a coincides with the central axis of the storage cavity 10a. One end of the compression spring 51 abuts against the center position of the cavity bottom wall of the storage cavity 10a, and the other end is arranged through the opening to be arranged in the limit groove 35a, so that the center line of the compression spring 51 coincides with the central axis of the storage cavity 10a. In this way, under the limitation of the limit groove 35a, the compression spring 51 will be located at the center position of the storage cavity 10a, and the position is not easy to be offset, so that the elastic force provided by the compression spring 51 to the plate body 31 will also act on the center position of the plate body 31, so that the plate body 31 is not easy to tip over, so that the packaged product supported by the plate body 31 can be placed in the storage cavity 10a more stably.

[0074] In one structural form, the support plate 30 also includes a limiting portion 35, which is connected to the plate surface of the plate body 31 facing the compression spring 51 and protrudes in a direction away from the plate body 31. The inner side wall of the limiting portion 35 cooperates with the plate surface of the plate body 31 facing the compression spring 51 to form a limiting groove 35a. Under such a setting, compared with the form in which the plate surface of the plate body 31 facing the compression spring 51 is recessed to form the limiting groove 35a, the plate body 31 in this form needs to have a certain thickness itself, so that the limiting groove 35a formed by the recess has a certain depth to limit one end of the compression spring 51. The plate body 31 of the present application does not need to be recessed to form the limiting groove 35a by itself, but forms the limiting groove 35a through the cooperation of the protruding limiting portion 35 and the plate body 31. Therefore, the thickness of the plate body 31 of the present application does not need to be too large. In this way, the volume of the plate body 31 can be reduced to reduce the weight of the plate body 31, so that the overall weight of the packaging box 100 is reduced, which is more suitable for transportation scenarios. Of course, in other structural forms, the limiting groove 35a of the present application can also be formed by the plate surface of the plate body 31 facing the compression spring 51, and the present application does not limit this.

[0075] Among them, the limiting part 35 can be an integrated structure with the plate body 31, so that the connection between the two is more stable and not easy to separate. Of course, the limiting part 35 can also be a detachable connection with the plate body 31, so that when the specifications of the compression spring 51 change, the limiting part 35 compatible with the compression spring 51 can be selected to be connected to the plate body 31.

[0076] Further, the depth of the limiting groove 35a of the present application is configured to be equal to the length of the compression spring 51 in the extreme compression state. It can be understood that when the compression spring 51 is in the extreme compression state, that is, the lowest height position that the plate body 31 can move in the box body 10, and when the compression spring 51 is in the extreme compression, when the depth of the limiting groove 35a is equal to the length of the compression spring 51 in the extreme compression state, the limiting groove 35a can limit the compression spring 51 to the greatest extent to ensure that the position of the compression spring 51 does not shift. Of course, the depth of the limiting groove 35a of the present application can also be configured to be less than the length of the compression spring 51 in the extreme compression state, and the present application does not limit this.

[0077] In order to facilitate the user to apply force to the plate body 31, please refer to Figure 3 to Figure 4 A hand-holding position 31a is formed on the board surface of the board body 31. In actual use, the user can first take out the sky box 11, and then put his hand into the ground box 13, so as to form a force point by hooking his fingers on the hand-holding position 31a, and then apply force to drive the board body 31 to rotate. In this way, the operation is more convenient to improve the user's experience. Of course, in addition to using fingers to cooperate with the hand-holding position 31a, the user can also use external tools to cooperate with the hand-holding position 31a. The present application does not limit the object that the hand-holding position 31a cooperates with.

[0078] In some structural forms, the number of the hand-gripping positions 31a can be two, and the two hand-gripping positions 31a are arranged at intervals along the circumference of the board body 31. With this arrangement, the user can extend the thumb and index finger of a single hand into the two hand-gripping positions 31a respectively to apply force to drive the board body 31 to rotate. In this way, the user's operation is more convenient and the user experience can be further improved.

[0079] In one embodiment, when the floor box 13 is configured as a paper box, if the floor box 13 is a single-layer paperboard structure, when the guide groove 15 is formed on the side wall of the storage cavity 10a, the thickness of the floor box 13 is too small, resulting in the guide groove 15 passing through the entire floor box 13, affecting the external aesthetics. When the side wall of the storage cavity 10a is provided with a guide rail 18, the single-layer paperboard has poor strength and cannot support the guide rail 18 well, which is prone to deformation.

[0080] Based on this, the floor box 13 of the present application may include a first paperboard layer and a second paperboard layer, the second paperboard layer is connected to the inner side of the first paperboard layer, and the inner wall surface of the second paperboard layer facing away from the first paperboard layer is formed as the cavity side wall of the storage cavity 10a. In this way, when the cavity side wall of the storage cavity 10a forms a guide groove 15, the guide groove 15 is only penetrated through the second paperboard layer, and the first paperboard layer can play a shielding role on the second paperboard layer, without affecting the external aesthetics of the floor box 13, and when the cavity side wall of the storage cavity 10a is provided with a guide rail 18, the overall strength of the floor box 13 can also be improved by the provision of the first paperboard layer and the second paperboard layer, so that it is not easy to deform and can better support the guide rail 18.
