Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box with shockproof function. Background Technology

[0002] Snap-fit ​​boxes, also known as snap-fit ​​wooden boxes, are packaging methods that use snap-fit ​​structures for assembly and fixation. They are typically used for product packaging that requires quick assembly, easy disassembly, or reuse. Compared to traditional tape or nail fixing, the snap-fit ​​design simplifies the packaging process and improves efficiency.

[0003] To facilitate stacking and improve the stability of stacked boxes, existing snap-fit ​​packaging boxes typically employ positioning structures for fixation. For example, Chinese Patent Publication No. CN219928353U discloses "a snap-fit ​​packaging box with shockproof function," which uses foam and pearl cotton. The foam is placed at the bottom of the top plate and the top of the base, thereby securing the top and bottom of the objects inside and reducing the contact between the sides of the objects and the sides of the packaging box. When the packaging boxes are stacked, the connecting plates of the lower packaging box are attached to the base of the upper packaging box on both sides. The screws inside the upper packaging box are then removed, inserted into the threaded holes of the connecting plate and the base, and tightened with nuts. This makes the connection between the packaging boxes more stable and reduces the possibility of the packaging boxes slipping.

[0004] However, in actual use, fixing stacked packaging boxes requires controlling multiple screws and nuts for connection, which is complicated. When large quantities of packaging boxes need to be transported, fixing stacked packaging boxes will significantly increase the labor burden of workers and also affect the efficiency of stacking and fixing, thus affecting the efficiency of transportation. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the complicated operation of fixing the stacked packaging boxes, the increased labor burden of workers when large quantities of packaging boxes need to be transported, and the impact on the efficiency of stacking, fixing and transportation. Therefore, a packaging box with shockproof function is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a shockproof packaging box, including a box body, with a connecting seat and a base respectively provided at the upper and lower ends of the box body. The base has a groove, and the connecting seat has a connecting block corresponding to the groove. The connecting seat has a control mechanism that cooperates with the connecting block. The groove has a pressure strip that cooperates with the control mechanism. A guide rod is movably inserted into the connecting seat, and a limiting component that cooperates with the guide rod is provided on the connecting seat. Shock-absorbing pads are provided on the side of the connecting seat and the base near the box body.

[0008] Furthermore, the control mechanism includes a trigger plate fixedly connected to the guide rod, a connecting plate rotatably mounted on the trigger plate, and the other end of the connecting plate rotatably connected to the connecting block.

[0009] Furthermore, the connecting seat is provided with a sliding groove, and the connecting block is fixedly provided with a slider that cooperates with the sliding groove, and a first spring is provided between the slider and the sliding groove.

[0010] Furthermore, the limiting component includes a movable groove formed on the connecting seat, a limiting plate being movably inserted into the movable groove, and a slot being formed on the guide rod to cooperate with the limiting plate.

[0011] Furthermore, a second spring is provided between the limiting plate and the movable groove, and a connecting rod is fixedly provided on one side of the limiting plate. The connecting rod passes through the connecting seat and is fixedly connected to a pull plate.

[0012] Furthermore, each of the connecting blocks is fixedly provided with a limiting protrusion, and the lower end of each limiting protrusion is provided with a first inclined surface, and the groove is provided with a second inclined surface corresponding to the first inclined surface.

[0013] The present invention provides a packaging box with shockproof function, which has the following advantages:

[0014] In this utility model, when stacking packaging boxes, the stacking operation can be completed by inserting the connecting seat and the base into each other. During the stacking process, the pressure strip inside the base applies force to the control mechanism, and the control mechanism is driven to fix the groove of the base, thereby tightly connecting the two stacked packaging boxes to prevent shaking.

[0015] Secondly, in this utility model, by setting a limiting component, the control mechanism is prevented from failing when the upper packaging box shakes up and down, thus preventing the stacked packaging boxes from disintegrating and avoiding safety hazards. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A shockproof packaging box includes a box body 1. The upper and lower ends of the box body 1 are respectively provided with a connecting seat 2 and a base 3. The base 3 has a groove 31. The connecting seat 2 is provided with a connecting block 4 corresponding to the groove 31. The connecting seat 2 is provided with a control mechanism 5 that cooperates with the connecting block 4. The groove 31 is provided with a pressure strip 6 that cooperates with the control mechanism 5. A guide rod 7 is movably inserted into the connecting seat 2. The connecting seat 2 is provided with a limiting component 8 that cooperates with the guide rod 7. Both the connecting seat 2 and the base 3 are provided with shock-absorbing pads on the side near the box body 1. The connecting seat 2 and the base 3 are both connected to the box body 1 by bolts. The shock-absorbing pads are preferably rubber pads.

[0024] In this utility model, when stacking packaging boxes, the stacking operation can be completed by inserting the connecting seat 2 and the base 3 into each other. During the stacking process, the pressure strip 6 inside the base 3 applies force to the control mechanism 5, and the control mechanism 5 is triggered to drive the connecting block 4 to move. The connecting block 4 fixes the base 3, thereby tightly connecting the two stacked packaging boxes to prevent shaking.

[0025] Furthermore, in this embodiment, the control mechanism 5 includes a trigger plate 51 fixedly connected to the guide rod 7. A connecting plate 52 is rotatably mounted on the trigger plate 51, and the two have an included angle. The other end of the connecting plate 52 is rotatably connected to the connecting block 4. The trigger plate 51 has a cross-shaped structure, and its four protruding parts are rotatably connected to the connecting plate 52. A connecting block 4 is rotatably mounted on each connecting plate 52. When the trigger plate 51 is moved downward by the pressure bar 6, the included angle between the trigger plate 51 and the connecting plate 52 changes, pushing the connecting block 4 to move, thereby applying force to the groove 31 of the base 3 from four angles, tightly connecting the base 3 and the connecting seat 2 to prevent loosening. At the same time, during the downward movement of the trigger plate 51, the guide rod 7 acts on it so that the movement trajectory does not change.

[0026] Furthermore, in this embodiment, the connecting seat 2 is provided with a sliding groove 53, and the connecting block 4 is fixedly provided with a slider 54 that cooperates with the sliding groove 53. A first spring 55 is provided between the slider and the sliding groove 53. When the connecting block 4 and the slider 54 are pushed and moved, the first spring 55 undergoes elastic deformation. When the force applied to the connecting block 4 is released, the first spring 55 resets and drives the slider 54 and the connecting block 4 to reset. The sliding groove 53 is preferably a T-shaped groove or a dovetail groove, and the slider 54 is preferably a corresponding T-shaped block or a dovetail block.

[0027] It should be noted that the limiting component 8 includes a movable groove on the connecting seat 2, in which a limiting plate 81 is movably inserted. The guide rod 7 has a slot 82 that cooperates with the limiting plate 81. When the guide rod 7 moves down to the preset position, that is, when the connecting block 4 abuts against the inner wall of the groove 31, the limiting plate 81 and the slot 82 are inserted to limit and fix the guide rod 7 and the trigger plate 51, preventing the connecting block 4 from loosening. In this embodiment, the limiting plate 81 has an inclined surface corresponding to the guide rod 7.

[0028] Furthermore, in this embodiment, a second spring 83 is provided between the limiting plate 81 and the movable groove, and a connecting rod 84 is fixedly provided on one side of the limiting plate 81. The connecting rod 84 passes through the connecting seat 2 and is fixedly connected to the pull plate 85. The second spring 83 applies force to the limiting plate 81 to prevent loosening and to reset the limiting plate 81. In some embodiments, an auxiliary groove is provided on the connecting seat 2, and the pull plate 85 is hidden in the auxiliary groove to save space.

[0029] More specifically, in this embodiment, each connecting block 4 is fixedly provided with a limiting protrusion 41, and the lower end of each limiting protrusion 41 is provided with a first inclined surface. The groove 31 is provided with a second inclined surface corresponding to the first inclined surface. When the pressure strip applies force to the control mechanism 5, that is, the base 3 of the upper packaging box approaches the connecting seat 2. At this time, the connecting block 4 gradually extends as the base 3 moves down. The purpose of setting the inclined surface is to prevent the connecting block 4 from being obstructed when it is inserted into the groove 31. That is, during the process of the connecting block 4 gradually extending, the two inclined surfaces are always in contact with each other, which will not obstruct the extension of the connecting block 4, nor will it obstruct the downward movement of the base 3.

[0030] Working method: When stacking, first align the base 3 of the upper packaging box with the connecting seat 2 of the lower packaging box, and gradually move the upper packaging box down. The base 3 will then slowly move down until the pressure strip 6 inside the base 3 contacts the trigger plate 51. As the base 3 continues to move down, the trigger plate 51 is pushed down by the pressure strip 6, and the angle between the trigger plate 51 and the connecting plate 52 changes, pushing the connecting block 4 to move, thereby approaching the inner wall of the groove 31 from four angles. When the base 3 and the connecting seat 2 are in complete contact, the connecting block 4 and the groove 31 are tightly abutted, thereby fixing the stacked packaging boxes. At the same time, the second spring 83 applies force to the limiting plate 81, and the limiting plate 81 is inserted into the slot 82 to limit and fix the guide rod 7 and the trigger plate 51.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
