Description

Technical Field

[0001] The utility model relates to the field of clamping components, and more particularly to a clamping component for a box body structure. Background Art

[0002] The anti-counterfeiting of packaging boxes is one of the safeguards for the interests of both buyers and sellers. At present, one of the anti-counterfeiting methods for packaging boxes lies in the opening structure of the packaging boxes, so that the opening of the packaging boxes requires destroying some irreparable structures, thereby judging whether the packaging boxes have been opened in advance by whether the specific structures are damaged.

[0003] The patent with the publication number CN109866971A discloses a rotary fastener, which improves the opening method from pulling the old fastener outward to rotary opening, avoiding the disadvantages that the packaging generates burrs, the edge of the packaging lock hole is uneven, affecting the beauty of the packaging, and it is easy to cut the user, affecting the trial experience, etc. However, the realization of the clamping of the barb on the nail seat to the box wall requires the nail body on the fastener to squeeze the barb, so that the two barbs move away from each other, and then clamp the box wall. In the process of repeatedly using the fastener, the clamping force of the barb will weaken. At the same time, since the barb is adapted to the side hole of the box body, if the fastener is assembled to the nail seat in advance, after the two barbs move away from each other, they cannot enter the side hole of the box body at the same time. Therefore, it is necessary to first assemble the nail seat to the box body, and then assemble the fastener to the nail seat. However, most packaging boxes are made of paper materials, which are easily deformed or even damaged when pressed. In order to avoid the foregoing situation, the assembly efficiency will decrease.

[0004] Based on the above, the applicant conceived a technical solution of setting clamping claws on the box body. When assembling the nail seat and the box body, the clamping of the nail seat and the inner wall of the box body is no longer realized by the deformation and reset of the clamping parts on the nail seat, but by the deformation of the clamping claws in cooperation with the nail seat to realize the assembly, so that the nail seat can be assembled with the fastener in advance as a whole. Specifically, refer to the patent applied by the applicant on the same day: an anti-counterfeiting component and a box body anti-counterfeiting structure. However, at present, most of the bases of packaging boxes are hollow structures. In order to reduce or avoid the pressure deformation of the base, transverse and longitudinal support structures are often arranged in the base, and the opening and closing of the clamping claws need to cooperate with the support structures to avoid the support structures from interfering with the opening of the clamping claws. In addition, in order to avoid the distance between the transverse support structures being too large and the height of the base being too high after providing enough space for the opening of the clamping claws, a notch needs to be provided at the connection between the support structure and the base for the clamping claws to give way when opening, which leads to a weakening of the support strength of the support structure.

Detailed implementation manners

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated herein can be arranged and designed in various different configurations.

[0032] The applicant applied for a patent with the publication number CN109866971A on December 4, 2017, which disclosed a rotary buckle. It improved the old-fashioned buckle that needed to be pulled outwards to be opened into a rotary opening, avoiding the generation of burrs in the packaging, uneven edges of the packaging lock holes, affecting the aesthetics of the packaging, and being prone to cutting users, affecting the trial experience, etc. However, the realization of the clamping of the barb on the nail seat to the box wall requires the nail body on the buckle to squeeze the barb, so that the two barbs move away from each other, and then clamp the box wall. During the repeated use of the buckle, the clamping force of the barb will weaken. At the same time, since the barb is adapted to the side hole of the box body, if the buckle is assembled to the nail seat in advance, after the two barbs move away from each other, they cannot enter the side hole of the box body at the same time. Therefore, it is necessary to first assemble the nail seat to the box body and then assemble the buckle to the nail seat. However, most packaging boxes are made of paper materials, which are prone to deformation and even damage when pressed. In order to avoid the foregoing situation, the assembly efficiency will decrease. Therefore, the applicant hopes that through the improvement of the nail seat structure, after the nail seat is assembled with the buckle, it can smoothly enter the side hole of the box body while realizing the self-clamping fixation of the nail seat and the box body without the assistance of the buckle. Specifically, refer to the patent applied by the applicant on the same day: an anti-counterfeiting component and a box body anti-counterfeiting structure. However, at present, most of the bases of packaging boxes are hollow structures. In order to reduce or avoid the compression deformation of the base, transverse and longitudinal support structures are often provided inside the base, and the opening and closing of the claw need to cooperate with the support structure to avoid the support structure from interfering with the opening of the claw. In addition, in order to avoid the distance of the transverse support structure being too large and the height of the base being too high after providing enough space for the opening of the claw, a notch needs to be provided at the connection between the support structure and the base for the claw to give way when opening, which weakens the support strength of the support structure.

[0033] Embodiment 1

[0034] As Figure 1 shown, a clamping component for a box body structure includes: a longitudinal support plate 1, a first cross plate 2, a second cross plate 3, a nail seat 4, and a claw 5; the longitudinal support plate 1 is used for supporting the inner wall of the box body base; the first cross plate 2 is connected to the longitudinal support plate 1; the second cross plate 3 is connected to the longitudinal support plate 1, the second cross plate 3 is located below the first cross plate 2, and the length of the second cross plate 3 is greater than the length of the first cross plate 2; there are at least two claws 5, and the space between the multiple claws 5 is for the nail seat 4 to pass through, and the free end of the claw 5 is used for clamping with the nail seat 4; the claw 5 is located between the first cross plate 2 and the second cross plate 3, and there is a gap between the positive projection of the first cross plate 2 on the horizontal plane and the positive projection of the claw 5 on the horizontal plane.

[0035] During the specific implementation process, the base can be set as Figure 9 shown, and the longitudinal support plate 1 can be set as Figure 10Two are provided as shown. Similarly, the nail seats 4 and the claws 5 can be provided on both sides of the base. The longitudinal support plate 1 can increase the bearing capacity of the base in the longitudinal direction. Each side of the second cross plate 3 can be connected to the inner wall of the base to increase the bearing capacity of the base in the horizontal direction. As Figure 1 shown, there is a gap between the first cross plate 2 and the side wall 6 of the base. The two ends of the first cross plate 2 adjacent to the longitudinal support plate 1 can be connected to the inner wall of the base. The aforementioned gap can allow the claw 5 to pass through. When the claw 5 is forced to expand outward under the extrusion of the nail seat 4, Figure 1 the lower claw 5 in the middle first abuts against the second cross plate 3, making it impossible to deform further. At this time, under the extrusion of the nail seat 4, only the upper claw 5 of the claw 5 deforms, and the free end of the claw 5 passes through the aforementioned gap.

[0036] In the prior art, the claw 5 is not provided on the box body, but the nail seat 4 is directly clamped with the inner wall of the box body. Therefore, during the clamping process, the deformed structure is located on the nail seat 4, which makes it impossible to assemble the nail seat 4 and the snap fastener 9 in advance. After the claw 5 is provided on the box body in this embodiment, the clamping structure on the nail seat 4 does not need to deform, but the clamping is realized by the deformation of the claw 5. Therefore, the nail seat 4 can be assembled with the snap fastener 9 in advance as a whole, thereby improving the assembly efficiency with the box body. Two or four claws 5 can be provided.

[0037] In order not to increase the height of the base, in this embodiment, instead of ensuring the opening space of the claw 5 by increasing the distance between the two cross plates, or providing gaps on both cross plates for the claw 5 to pass through, a gap is provided on the first cross plate 2. The second cross plate 3 is still fully connected to the inner wall of the base, and only the support strength of the support structure is ensured as much as possible on the premise of satisfying the opening of the claw 5.

[0038] Embodiment 2

[0039] As Figure 1-3 shown, in this embodiment, it includes: a base side wall 6, the base side wall 6 is provided with a first through hole 61, the claw 5 is connected to the side wall of the first through hole 61, the nail seat 4 passes through the first through hole 61 and is clamped with the claw 5, and one end of the second cross plate 3 far from the longitudinal support plate 1 is connected to the base side wall 6.

[0040] During the specific implementation process, the first through hole 61 can be circular, and the claw 5 can be clamped with the side wall of the nail seat 4. In order to prevent the second cross plate 3 from deforming under the extrusion of the claw 5, one end of the second cross plate 3 far from the longitudinal support plate 1 is connected to the base side wall 6 to increase its stability.

[0041] Embodiment 3

[0042] As Figure 2-3As shown, in this embodiment, the nail base 4 includes a fastening portion 41, a resisting block 42, and a splitting piece 43; the resisting block 42 is connected to the fastening portion 41, and when the resisting block 42 is clamped with the claw 5, the fastening portion 41 is located outside the base; the splitting piece 43 is connected to the fastening portion 41, and the splitting piece 43 is closer to the edge of the fastening portion 41 than the resisting block 42.

[0043] During the specific implementation process, the fastening portion 41 can be as Figure 2 shown, including an outer ring body and an inner ring body. The inner ring body is connected to the outer ring body through connecting ribs, and the inner ring body is used for the insertion of the fastening nail 9. In addition, there can be a certain height difference between the top wall of the outer ring body and the top wall of the inner ring body. When the fastening nail 9 and the nail base 4 are assembled, the top walls of the nail base 4 and the fastening nail 9 are almost flush as Figure 7 shown.

[0044] Exemplarily, the nail base 4 and the fastening nail 9 can be made of different materials. For example, the fastening nail 9 can be made of a metal material: copper or silver. The metal material can increase the texture of the fastening nail 9, especially the texture of the surface pattern of the fastening nail 9. The nail base 4 can be made of a plastic material, and through an injection molding process, the forming of the complex structure of the nail base 4 can be realized. Of course, both can also be made of plastic materials.

[0045] In order for the splitting piece 43 to have a good splitting effect, the side wall of the splitting piece 43 should not be too thick and can be between 0.5 - 2 mm.

[0046] Embodiment 4

[0047] In order to further increase the structural strength of the base, improvements are made on the basis of Embodiment 3. As Figure 1 shown, in this embodiment, the side wall 6 of the base is provided with a first annular hole 62 for the splitting piece 43 to pass through, and the first through hole 61 is located in the enclosed area of the first annular hole 62; when the nail base 4 is clamped with the claw 5, at least one claw 5 is located in the lower half area of the first annular hole 62 and is simultaneously located below the second cross plate 3.

[0048] During the specific implementation process, since the splitting piece 43 needs to rotate, the first annular hole 62 is provided to provide a rotation space for it. As Figure 1 shown, at least one claw 5 is arranged below the second cross plate 3, and the claw 5 can be in contact with the second cross plate 3. When the base is subjected to a longitudinal pressure, the claw 5 can provide a supporting force for the second cross plate 3, thereby increasing the bearing capacity of the base.

[0049] Embodiment 5

[0050] In order to achieve the anti-counterfeiting of the packaging, improvements are made on the basis of Embodiment 4. As Figure 4-5As shown, in this embodiment, it includes: a cover body side wall 7, and the cover body side wall 7 is provided with a second through hole 71 for the abutting block 42 to pass through and a second annular hole 72 for the splitting disk to pass through; the outer ring wall of the second annular hole 72 is connected to the inner ring wall of the second annular hole 72 through a connecting section 8.

[0051] During the specific implementation process, as Figure 4 shown, after the nail seat 4 is assembled with the packaging box, it not only inserts into the cover body side wall 7 but also passes through the base side wall 6. As Figure 5 shown, the cover body is provided with a connecting section 8, and 4 connecting sections 8 can be set. After the nail seat 4 is assembled, the splitting piece 43 is located in the annular hole. When the packaging is intact, the connecting section 8 is not damaged and the cover body cannot be separated from the base. When wanting to open the packaging box, the nail seat 4 can be rotated, so that the splitting piece 43 cuts open the connecting section 8, and then the cover body can be removed. Under the anti-counterfeiting structure of this embodiment, if the connecting section 8 is not damaged, the packaging box cannot be opened. Therefore, it can be judged whether the product packaging has been opened in advance or whether the product in the box has been replaced by whether the connecting section 8 is damaged.

[0052] Embodiment 6

[0053] In order for the abutting block 42 to better pass through the enclosed area formed between the claws 5, an improvement is made on the basis of Embodiments 1-5. As Figure 4 and Figure 8 shown, in this embodiment, the abutting block 42 includes: a first end portion 421 and a second end portion 422; the first end portion 421 is connected to the bottom wall of the fastening portion 41; the second end portion 422 is connected to one end of the first end portion 421 away from the fastening portion 41. The side wall of the second end portion 422 includes an inclined wall 4221, and during the process of the inclined wall 4221 extending away from the fastening portion 41, it gradually converges inward. The bottom wall of the second end portion 422 is used to abut against the end of the claw 5. When the abutting block 42 is engaged with the claw 5, the first end portion 421 and the second end portion 422 are located on both sides of the claw 5; the claw 5 at least includes an inclined portion 51, and during the process of the free end of the inclined portion 51 extending towards the abutting block 42, it gradually converges inward, and the slope of the side wall of the inclined portion 51 close to the first end portion 421 is greater than that of the inclined wall 4221.

[0054] During the specific implementation process, as Figure 4As shown, the second end portion 422 and the first end portion 421 are respectively located on both sides of the clamping jaw 5. At the connection between the second end portion 422 and the first end portion 421, there is a step difference between the side wall of the second end portion 422 and the side wall of the first end portion 421. This step difference causes the second end portion 422 to have an annular bottom wall, and the free end of the clamping jaw 5 abuts against the bottom wall of the second end portion 422. The inclined wall 4221 is provided so that the end of the second end portion 422 far from the first end portion 421 can smoothly enter the enclosed space of the clamping jaw 5. Then, under the action of the inclined wall 4221, the clamping jaw 5 gradually opens. When the second end portion 422 completely passes through the enclosed space of the clamping jaw 5, the clamping jaw 5 resets. With the cooperation between the free end of the clamping jaw 5 and the bottom wall of the second end portion 422, the clamping and fixing of the nail seat 4 is achieved. The slope of the side wall of the inclined portion 51 close to the first end portion 421 is greater than that of the inclined wall 4221 so that the second end portion 422 can push the clamping jaw 5 outwards during the forward movement.

[0055] Embodiment 7

[0056] In order to improve the stability when the second end portion 422 passes through the enclosed space of the clamping jaw 5, an improvement is made on the basis of Embodiment 6, as Figure 4 shown. In this embodiment, the clamping jaw 5 further includes: a horizontal portion 52, and the horizontal portion 52 is connected to one end of the inclined portion 51 close to the fastening portion 41; the side wall of the second end portion 422 includes a horizontal wall 4222 that cooperates with the horizontal portion 52, and the horizontal wall 4222 is connected to one end of the inclined wall 4221 close to the fastening portion 41.

[0057] During the specific implementation process, since the slope of the side wall of the inclined portion 51 close to the first end portion 421 is greater than that of the inclined wall 4221, the contact between the second end portion 422 and the clamping jaw 5 is a line contact, and the rest of the positions are basically in a suspended state, resulting in poor stability of movement. Therefore, in this embodiment, the horizontal wall 4222 and the horizontal portion 52 are provided so that during the process of the second end portion 422 passing through the enclosed space of the clamping jaw 5, the horizontal portion 52 and the horizontal wall 4222 abut against each other, and through the limit and guidance of the horizontal portion 52, the stability of the movement of the abutting block 42 is achieved.

[0058] Embodiment 8

[0059] As Figure 6 shown. In this embodiment, it includes: a snap nail 9, and the snap nail 9 includes: a cap body 91 and a clamping member 92; the clamping member 92 is connected to the bottom wall of the cap body 91; the fastening portion 41 is provided with an opening 411 for the clamping member 92 to be inserted.

[0060] During the specific implementation process, the surface of the snap nail 9 can be as Figure 7The shown design pattern enhances the aesthetic appearance and product recognition. The snap-in part 92 is used for the connection between the fastening nail 9 and the nail base 4. The snap-in part 92 can be made of an elastic material. A clamping groove can be arranged in the through hole. When the snap-in part 92 is inserted into the through hole at first, the snap-in part 92 is deformed under the pressure of the side wall of the through hole. After reaching the clamping groove, under the action of the resilience force, the snap-in part 92 enters the clamping groove to realize the connection between the fastening nail 9 and the nail base 4. The abutting block 42 is used for the snap connection with the inner wall of the packaging box.

[0061] Embodiment 9

[0062] In order to reduce the possibility of damage to the snap-in part 92 and improve the movement stability of the snap-in part 92, improvements are made on the basis of Embodiment 8, as Figure 8 shown. In this embodiment, a cavity is arranged in the first end portion 421, and the cavity communicates with the through hole 411; the snap connection assembly further includes: a guide rod 10, the inner wall of the first end portion 421 is connected to the guide rod 10, the free end of the guide rod 10 extends towards the through hole 411 and enters the through hole 411, a gap is left between the guide rod 10 and the side wall of the through hole 411, and the width of the gap is greater than the maximum width of the snap-in part 92.

[0063] During the specific implementation process, the shape of the snap-in part 92 is not specifically limited in this embodiment and can be set with reference to Figure 6 shown. In this embodiment, setting the width of the gap to be greater than the maximum width of the snap-in part 92 is to enable the snap-in part 92 to smoothly enter the through hole, and at the same time enable the snap-in part 92 to have a certain movement space after being pressured by the side wall of the through hole. The maximum width of the snap-in part 92 refers to Figure 8 in the cross-sectional view shown, the maximum distance between the upper and lower sides of the snap-in part 92. The upper side refers to the side close to the side wall of the through hole, and the lower side refers to the side close to the guide rod 10.

[0064] During the process of the snap-in part 92 sliding along the side wall of the through hole, if the fastening nail 9 is subjected to a radial force, the deformation of the snap-in part 92 is relatively large. Through the limitation and guidance of the guide rod 10, while reducing the possibility of damage to the snap-in part 92, the movement of the snap-in part 92 can be made more stable.

[0065] Exemplarily, the guide rod 10 can be as Figure 8 shown, connected to the bottom wall of the first end portion 421. At the same time, in order to increase the strength of the guide rod 10, the end of the guide rod 10 close to the bottom wall of the first end portion 421 can be larger than the end of the guide rod 10 close to the through hole.

[0066] Embodiment 10

[0067] In order to simplify the forming process of the nail base 4, improvements are made on the basis of Embodiment 8, as Figure 1 and Figure 8As shown, in this embodiment, an inner wall of the opening 411 near one end of the abutting block 42 extends outwardly from the opening 411 to form a clamping wall, and the clamping wall is connected to an inner wall of the cavity; the clamping member 92 includes two clamping pieces 921, and an outer hook portion 922 adapted to the clamping wall is provided at one end of the clamping piece 921 away from the fastening portion 41, and the guide rod 10 can be received between the two clamping pieces 921.

[0068] During the specific implementation process, the outer hook portion 922 can be as Figure 6 or Figure 8 shown, and extends in a direction away from the guide rod 10 as a whole. In order for the clamping member 92 to enter the through hole more conveniently, it can also be as Figure 6 shown, and one end of the outer hook portion 922 away from the cap body 91 is provided as an inclined wall, so that the distance between free ends of the two clamping members 92 is less than the inner diameter of the opening 411, and the free ends of the two clamping members 92 can more easily enter the opening 411. When the inclined wall completely enters the through hole, since the distance between outer walls of the two outer hook portions 922 is greater than the inner diameter of the opening 411, the clamping member 92 is pressed. When the outer hook portion 922 disengages from the opening 411, the clamping member 92 rebounds, and the clamping piece 921 abuts against the inner wall of the through hole. Under the cooperation and limitation of the outer hook portion 922 and the abutting wall, the snap fastener 9 is clamped and fixed and is difficult to be taken out from the nail base 4.

[0069] Compared with the structure in which the cavity is separated from the opening 411 and a clamping groove is provided on the side wall of the through hole to achieve clamping, in this embodiment, the cavity of the first end portion 421 is communicated with the opening 411, and the clamping of the clamping member 92 is achieved through a stepped structure formed by the inner walls of the two, which can simplify the forming process of the nail base 42.

[0070] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
