Description

Technical Field

[0001] This utility model relates to the field of anti-detachment cardboard box through-hole technology, specifically to a self-locking panel device and a matching handle, and a cardboard box with a self-locking panel device. Background Technology

[0002] Cardboard boxes are typically equipped with handle holes for easy handling (as shown in the attached drawings of patent publication number CN213110120U). Figure 3 As shown in reference numerals 1321 and 1322, it achieves portability through a handle structure made of deformable material.

[0003] This type of handle 1 is mainly composed of a lifting part 101 and an anti-detachment hook 102 (as shown in the specification attached to this application). Figure 1 As shown, the lifting part 101, which serves as the handhold, is often designed as an arc-shaped or flat strip structure, with anti-slip hooks 102 extending from both ends at specific angles.

[0004] During the installation of handle 1, the operator needs to use external force to squeeze handle 1 to cause the anti-detachment hook 102 to undergo elastic deformation. Specifically, when external force is applied, the angle between the anti-detachment hook 102 and the lifting part 101 decreases. As the angle decreases, the lateral dimension of the anti-detachment hook 102 gradually approaches the width of the handle 1 hole, and finally it can be smoothly inserted into the pre-set handle 1 hole of the carton.

[0005] Normally, because the material of handle 1 has resilience, when the external force is removed, the anti-detachment hook 102 will try to return to the original angle state. This resilience characteristic makes the anti-detachment hook 102 form a snap-fit ​​structure with the carton after the handle 1 is inserted into the handle 1 hole.

[0006] However, in actual use, the opening size of the hole for the carton handle 1 is usually only slightly smaller than the lateral width of the anti-detachment hook 102 in its naturally unfolded state. While this design margin facilitates the insertion of the handle 1, it also makes the anti-detachment hook 102 prone to slipping out of the hole in the handle 1. In this case, directly reducing the diameter of the hole in the handle 1 to enhance the fixing effect, although it can improve the anti-detachment performance, would significantly increase the difficulty of installing the handle 1. Therefore, a new solution is needed to address the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] The purpose of this invention is to provide a self-locking panel device to solve the problem mentioned in the background art that existing anti-detachment hooks are prone to slipping out of the handle hole.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the present invention provides the following technical solution: a self-locking panel device, comprising a panel with a handle opening on its surface, and an anti-detachment mechanism located at the edge of the handle opening for locking the handle;

[0011] The anti-detachment mechanism includes a snap-fit ​​component disposed on one edge of the handle opening and extending into the handle opening. The end of the snap-fit ​​component away from the handle opening is fixedly connected to the panel. When the handle is inserted into the handle opening, the snap-fit ​​component will automatically snap into the lifting part and the anti-detachment hook.

[0012] When the handle passes through the handle opening and is pulled in the opposite direction, the end of the anti-disengagement hook extends beyond the connection point between the latch and the panel, and overlaps with the back of the panel.

[0013] Furthermore, the snap-fit ​​component is integrally formed with the panel.

[0014] Furthermore, the snap-fit ​​component is formed by cutting a line on the panel, and the two ends of the line away from the handle opening extend in opposite directions to form a hook portion.

[0015] Furthermore, a reinforcing layer is provided on the back of the panel and at the edge of the handle opening.

[0016] Furthermore, the reinforcing layer is formed by folding after creating two knife lines on the panel.

[0017] The handle that works with the self-locking panel device includes a lifting part, both ends of which are provided with anti-disengagement hooks at an angle.

[0018] A carton with a self-locking panel device includes a first side panel, a second side panel, a third side panel, and a fourth side panel that are connected to each other, and a self-locking panel device is installed on any of the side panels.

[0019] A carton with a self-locking panel device includes a first side panel, a second side panel, a third side panel, and a fourth side panel that are connected to each other, and a top panel extends from the top of any of the side panels, the top panel being provided with a self-locking panel device.

[0020] Furthermore, the cardboard box is a corrugated cardboard box, a kraft paper box, or a cardboard box.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. By adding a snap-fit ​​component inside the handle opening, and because the end of the snap-fit ​​component away from the handle opening is fixedly connected to the panel, the snap-fit ​​component has a movable end (the end facing the handle opening) and a fixed end (the end away from the handle opening). When the handle is inserted, the snap-fit ​​component is forced to deform inward towards the panel, allowing the handle end to smoothly pass through the handle opening. Once the handle is inserted, the snap-fit ​​component reduces the original diameter of the handle opening, thus creating a more stable snap-fit ​​structure between the lifting part and the anti-slip hook, preventing the handle from slipping off.

[0023] 2. By limiting the size of the snap-fit ​​component, it can match the handle structure in the existing technology, so that when the handle passes through the handle opening and is pulled in the opposite direction, the anti-disengagement end extends beyond the connection point between the snap-fit ​​component and the panel and extends to overlap with the back of the panel, avoiding the force being fully applied at the connection point between the snap-fit ​​component and the panel, thus improving the service life and stability of the snap-fit ​​component.

[0024] 3. By setting a hook at the end of the snap-fit ​​component, the connection size and connection stability between the snap-fit ​​component and the panel are increased. Without the hook, when the snap-fit ​​component is pulled, the two ends of the first blade line are likely to gradually approach each other in a ">" shape, causing the snap-fit ​​component to be torn apart.

[0025] 4. This self-locking panel device can be adapted to existing handles with lifting parts and anti-detachment hooks. In addition, the self-locking panel device can be installed on different cartons and on different surfaces of the cartons, such as the side, top or other surfaces of the cartons. It can also be installed inside corrugated cartons, kraft paper cartons or cardboard cartons. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 2 This utility model provides multiple technical solutions: Among them, a self-locking panel device includes a panel 2 with a handle opening 201 on its surface, and also includes a handle 1 located at the edge of the handle opening 201 for locking (e.g., ...). Figure 1 The anti-detachment mechanism 3 (as shown)

[0036] Please see Figure 2 The anti-detachment mechanism 3 includes a snap-fit ​​member 301 disposed on one edge of the handle opening 201 and extending into the handle opening 201. The end of the snap-fit ​​member 301 away from the handle opening 201 is fixedly connected to the panel 2. Preferably, the snap-fit ​​member 301 is integrally formed with the panel 2, requiring no additional fixing operation. Figure 3 and Figure 4 As shown, when the handle 1 is inserted into the handle opening 201, the locking piece 301 will automatically engage with the angle between the lifting part 101 and the anti-disengagement hook 102.

[0037] like Figure 4 As shown, in order to avoid the pulling force of the handle 1 being fully applied to the connection between the snap fastener 301 and the panel 2, when the handle 1 passes through the handle opening 201 and is pulled in the opposite direction, in some preferred embodiments, the end of the anti-detachment hook 102 extends beyond the connection point between the snap fastener 301 and the panel 2 and extends to overlap with the back of the panel 2, so that the pulling force is applied to the panel 2 through the end of the anti-detachment hook 102, thereby improving the service life and stability of the snap fastener 301.

[0038] like Figure 3 and Figure 4As shown, in some embodiments, the snap-fit ​​member 301 is formed by cutting a line 202 on the panel 2. The line 202 is U-shaped, with both ends located away from the handle opening 201. This gives the snap-fit ​​member 301 a movable end (facing the handle opening 201) and a fixed end (away from the handle opening 201). When the handle 1 is inserted, the snap-fit ​​member 301 is forced to deform inward towards the panel 2, allowing the end of the handle 1 to smoothly enter the handle opening 201. After the handle 1 enters the handle opening 201, because the snap-fit ​​member 301 reduces the original diameter of the handle opening 201, the snap-fit ​​member 301 more stably connects the lifting part 101 and the anti-disengagement hook 102, forming a stable snap-fit ​​structure and preventing the handle 1 from slipping off.

[0039] like Figure 4 As shown, in order to further ensure the stability of the snap-fit ​​301, in a preferred embodiment, the two ends of the blade line 202 away from the handle opening 201 extend in opposite directions to form a hook portion 2021. By providing the hook portion 2021 at the end of the snap-fit ​​301, the connection size and connection stability between the snap-fit ​​301 and the panel 2 are increased. Without the hook portion 2021, when the snap-fit ​​301 is pulled, the two ends of the blade line 202 are likely to gradually approach each other in a ">" or "<" shape, causing the snap-fit ​​301 to be torn off.

[0040] Please see Figure 2 and Figure 3 To ensure the structural stability of the handle opening 201, in some embodiments, a reinforcing layer 203 can be provided on the back of the panel 2 and at the edge of the handle opening 201. The reinforcing layer 203 can be fixed by means of adhesive, rivets, etc. In addition, the reinforcing layer 203 can also be made of paper, plastic, rubber, or any other material with a certain degree of hardness. In order to save costs and processes, in some embodiments, the reinforcing layer 203 can also be formed by folding after cutting a second slit line 204 on the panel 2. It is worth mentioning that when the reinforcing layer 203 is formed by folding, a first slit line 202 also needs to be cut on the reinforcing layer 203 to form a snap-fit ​​member 301.

[0041] Please see Figure 1 The utility model also provides a handle that works with a self-locking panel device. The handle 1 includes a lifting part 101. Both ends of the lifting part 101 are provided with anti-disengagement hooks 102 at an angle. The anti-disengagement hooks 102 and / or the lifting part 101 have a certain deformation capability, which can achieve the effect of the anti-disengagement hooks 102 penetrating the handle opening 201.

[0042] Please see Figure 5The present invention also provides a carton with a self-locking panel device, including a first side panel 4, a second side panel 5, a third side panel 6, and a fourth side panel 7 that are connected to each other. A self-locking panel device is installed on any side panel. At this time, the panel 2 of the self-locking panel device refers to the corresponding side panel.

[0043] Please see Figure 6 and Figure 7 The utility model also provides a carton with a self-locking panel device, including a first side panel 4, a second side panel 5, a third side panel 6, and a fourth side panel 7 that are connected to each other. A top panel 8 extends from the top of any side panel, and a self-locking panel device is provided on the top panel 8. In this case, the panel 2 of the self-locking panel device refers to the top panel 8.

[0044] It is worth mentioning that the cardboard box of this utility model can be a corrugated cardboard box, a kraft paper box, or a cardboard box, as well as a composite cardboard box made of various materials combined with paper materials.

[0045] Working principle: When the handle 1 is inserted into the carton using this design, the locking component 301 is forced to deform inward towards the panel 2, allowing the end of the handle 1 to smoothly enter the handle opening 201. After the handle 1 enters the handle opening 201, because the locking component 301 reduces the original diameter of the handle opening 201, the locking component 301 more stably forms a stable locking structure between the lifting part 101 and the anti-disengagement hook 102, thereby preventing the handle 1 from slipping off.

[0046] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
