Description

Technical Field

[0001] This utility model relates to the field of packaging positioning structures, specifically a foam packaging positioning structure. Background Technology

[0002] Foam packaging is a lightweight cushioning packaging product made of foam materials such as polystyrene (EPS) and polyurethane (PU). It forms a shock-absorbing layer through a dense internal structure of independent air bubbles, which can effectively absorb the impact during transportation and protect fragile items. One typical application is a specially designed foam box for transporting fruit. This type of packaging usually uses high-density EPS material and uses customized grooves or grid designs to fix the position of the fruit. It is also equipped with ventilation holes to balance the humidity inside the box. It can prevent collisions and squeezing and delay the oxidation of the fruit. It is especially suitable for long-distance transportation and retail display of delicate fruits such as grapes, strawberries, and lychees.

[0003] However, current foam packaging, such as boxes, is secured by spring straps or straps during transportation. But in practice, due to improper control of the binding force, such as excessive tightening or repeated binding in the same position on the box for a long time, the edges of the foam box are subjected to concentrated compressive stress. The fragile structural layer is prone to irreversible plastic deformation, which can lead to dents, cracks or even delamination at the four corners or edges of the box. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a foam packaging positioning structure to solve the technical problem that existing foam packaging boxes suffer from irreversible plastic deformation due to improper control of binding force during transportation, such as excessive tightening or repeated binding in the same position of the box for a long time. This causes the edges of the foam box to be subjected to concentrated compressive stress continuously, which leads to dents, cracks or even delamination in the four corners or edge areas of the box, ultimately affecting the packaging protection performance and the safety of cargo transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foam packaging positioning structure, including a positioning rope and foam packaging, wherein the foam packaging includes a box body, and mounting grooves are provided at the front and rear ends of the box body, and a protective mechanism is installed in the mounting grooves;

[0006] The protective mechanism includes a mounting base that is adapted to a mounting groove. The mounting base is fixedly connected to the mounting groove by strong adhesive, and a damping rotating rod is mounted on the mounting base.

[0007] By adopting the above technical solution, the protective mechanism achieves rapid pre-installation and fixation through the compatibility of the mounting base and the mounting groove, combined with strong adhesive, providing a stable support foundation for the damping rod and avoiding the stress from directly acting on the foam during binding, which could lead to local crushing.

[0008] Furthermore, the two ends of the positioning rope are fixed to the vehicle, and the positioning rope passes around two damping rotating rods to fix multiple sets of foam packaging from top to bottom.

[0009] By adopting the above technical solution, the positioning rope is wrapped around the pair of damping rotating rods and fixed to the transport vehicle to achieve lateral restraint on the multi-layer stacked foam packaging and prevent the stack from tilting.

[0010] Furthermore, the protective mechanism is used to prevent the edges of the foam packaging from being damaged due to excessive binding of the positioning rope.

[0011] By adopting the above technical solution, the protective mechanism transforms the concentrated compressive stress of the positioning rope into dynamic rolling friction, preventing the edges of the foam packaging from being crushed or worn due to excessive binding.

[0012] Furthermore, the top of the box is provided with a cover edge, and a cover edge is provided on the cover edge.

[0013] By adopting the above technical solution, the overlapping edge of the top of the box and the cover groove at the bottom of the box cover fit together and form a preliminary seal with the cover edge to prevent the box cover from shifting horizontally.

[0014] Furthermore, four spherical protrusions are provided at the four corners of the edge of the cover, and the four spherical protrusions are interlocked with the cover by an interference fit.

[0015] By adopting the above technical solution, the spherical protrusions at the four corners of the cover are interference-fitted with the box cover, which enhances the locking force at the corners of the box cover and resists loosening caused by transportation vibration.

[0016] Furthermore, a lid is provided on the top of the box body, and a cover groove is provided at the bottom of the lid. The cover groove is engaged with the cover edge, and the cover groove and the cover edge are locked together.

[0017] By adopting the above technical solution, the cover groove and the overlapping edge of the box cover are further engaged after being mounted, and the spherical protrusion of the weight 5 forms a double closure guarantee, improving the overall sealing performance.

[0018] Furthermore, the mounting base forms dynamic contact with the positioning rope through a damping rotating rod. The damping rotating rod can rotate around its axis to disperse the concentrated compressive stress of the positioning rope on the edge of the foam packaging. The surface of the damping rotating rod and the contact surface with the positioning rope are smooth curved surfaces to reduce frictional damage.

[0019] By adopting the above technical solution, the rotational characteristics of the damping rod transform the static binding force of the positioning rope into dynamic rolling contact, and the smooth curved surface further reduces rope wear.

[0020] Furthermore, the top of the box lid is provided with two protrusions, the bottom of the box body is provided with a groove, and multiple foam packages are spliced ​​together by the protrusions and the groove.

[0021] By adopting the above technical solution, the protrusion on the top of the box lid and the groove on the bottom of the box body are interference-fitted to achieve vertical self-locking of multi-layer foam packaging and prevent stacking displacement.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by setting up an installation groove, a protective mechanism, a mounting base, a damping rotating rod, strong adhesive, and a positioning rope, wherein the protective mechanism is fixed by the mounting base and the installation groove through the fit and fit, and combined with the dynamic contact design of the damping rotating rod and the positioning rope, allows the positioning rope to disperse the concentrated compressive stress on the edge of the box through the rotation of the damping rotating rod when fixing the foam packaging. At the same time, the smooth curved surface of the damping rotating rod reduces friction damage, thereby avoiding the problem of deformation and cracking of the box edge caused by excessive binding or long-term fixing. It solves the technical defects of existing foam packaging that cause structural damage and protective failure during transportation due to improper binding methods.

[0024] 2. This utility model incorporates an overlapping edge, a snap-on edge, spherical protrusions, protrusions, and grooves. The overlapping edge and snap-on edge form a preliminary snap-on structure between the box body and the box lid. The spherical protrusions on the edge of the snap-on edge further enhance the connection stability between the box lid and the box body through an interference fit. At the same time, the protrusions on the top of the box lid and the grooves on the bottom of the box body form a stacking positioning structure. This allows multiple foam packages to be precisely spliced ​​and stably stacked in the vertical direction through the interlocking of protrusions and grooves. This solves the technical problem that existing foam packages are prone to misalignment, slippage, or tipping during stacking and transportation, and improves the overall impact resistance of multi-layer packaging.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0031] A positioning structure based on foam packaging, such as Figure 1-4 As shown, it includes a positioning rope 1 and a foam packaging 2. The foam packaging 2 includes a box body 201. The front and rear ends of the box body 201 are provided with mounting grooves 206, and a protective mechanism 3 is installed in the mounting grooves 206.

[0032] The protective mechanism 3 includes a mounting base 301, which is adapted to the mounting groove 206. The mounting base 301 is fixedly connected to the mounting groove 206 by strong adhesive 303. A damping rod 302 is installed on the mounting base 301. The shape of the mounting base 301 of the protective mechanism 3 is adapted to the mounting groove 206 of the box 201. The mounting base 301 is firmly bonded to the mounting groove 206 by strong adhesive 303, ensuring that the mounting base of the damping rod 302 forms a rigid connection with the foam box 201. This prevents the foam material at the edge of the mounting groove 206 from tearing or deforming due to the continuous tension of the positioning rope 1 during transportation. At the same time, it provides stable support for the rotation function of the damping rod 302 and improves the durability of the overall structure.

[0033] See Figure 1 , Figure 2 The two ends of the positioning rope 1 are fixed to the vehicle, and the positioning rope 1 passes around two damping rotating rods 302 to fix multiple sets of foam packaging 2 from top to bottom. The two ends of the positioning rope 1 are fixed to the transport vehicle such as the anchor point of the carriage, and the middle passes around the damping rotating rods 302 at the front and rear ends of the box 201. The multiple sets of foam packaging 2 stacked from top to bottom are horizontally tied together by the tension force. The rolling characteristics of the damping rotating rods 302 are used to reduce frictional resistance, so that the binding force of the positioning rope 1 is evenly transmitted to each layer of the box, avoiding horizontal displacement or overturning between the boxes 201 due to bumps when stacking multiple layers.

[0034] See Figure 1 , Figure 4 The protective mechanism 3 is used to prevent the positioning rope 1 from being over-tied, which could damage the edges of the foam packaging 2. The damping rod 302 in the protective mechanism 3 rotates around the axis when the positioning rope 1 is tied, converting the static rope knot pressure into dynamic rolling friction, dispersing the concentrated compressive stress of the positioning rope 1 on the edge corners of the box 201, and preventing the foam material from being crushed due to stress concentration. At the same time, the smooth curved surface of the damping rod 302 reduces the coefficient of friction with the positioning rope 1, reduces rope wear and foam debris generation, and extends the service life of the packaging structure. Example 2:

[0035] See Figure 1 , Figure 2 The top of the box body 201 is provided with a cover edge 203, and a cover edge 204 is provided on the cover edge 203. The cover edge 203 at the top of the box body 201 is embedded in the cover groove at the bottom of the cover 202. The planar support of the cover edge 203 restricts the vertical sway of the cover 202. At the same time, the cover edge 204 on the outside of the cover edge 203 forms a snap-fit ​​interference with the inner wall of the cover groove, restricting the horizontal displacement of the cover 202. This achieves the initial closing and locking of the cover 202 and the box body 201, providing a positioning basis for the subsequent interference fit of the spherical protrusion 205.

[0036] See Figure 1 , Figure 4 The cover has four spherical protrusions 205 at the four corners of the edge 204, and the four spherical protrusions 205 are connected to the cover 202 by interference fit. The spherical protrusions 205 at the four corners of the edge 204 are pressed into the corresponding holes of the cover 202 by interference fit. The guiding property of the spherical surface is used to reduce the fastening resistance, and after closing, the elastic deformation of the spherical surface and the hole wall generates a continuous locking force, especially strengthening the anti-warping ability of the four corner areas of the cover 202, preventing the cover 202 from popping open locally due to transportation vibration, and forming a complementary seal with the flat mounting of the overlapping edge 203.

[0037] See Figure 1 , Figure 4 A lid 202 is provided on the top of the box body 201. A cover groove is provided at the bottom of the lid 202. The cover groove is engaged with the overlapping edge 203 and the cover groove is locked with the overlapping edge 203. The cover groove at the bottom of the lid 202 is first engaged with the overlapping edge 203 at the top of the box body 201 to form a preliminary planar support. Then, the inner wall of the cover groove and the side wall of the locking edge 204 are locked together by the inclined surface to generate a lateral constraint force. This locking force works together with the interference fit of the spherical protrusion 205 in the 5th element to limit the lid 202 in both vertical and horizontal directions, forming a double anti-loosening mechanism, especially to avoid gaps in the closed interface caused by high-frequency vibration during transportation.

[0038] See Figure 3 , Figure 4The mounting base 301 forms dynamic contact with the positioning rope 1 through the damping rotating rod 302. The damping rotating rod 302 can rotate around its axis to disperse the concentrated compressive stress of the positioning rope 1 on the edge of the foam packaging 2. The surface of the damping rotating rod 302 in contact with the positioning rope 1 is a smooth curved surface to reduce frictional damage. When the positioning rope 1 is tensioned, the damping rotating rod 302 on the mounting base 301 rotates freely around its axis, so that the contact form between the positioning rope 1 and the rotating rod is changed from static sliding friction to dynamic rolling friction, which significantly reduces the frictional resistance when the rope moves and transforms the concentrated compressive stress of the positioning rope 1 on the edge of the box 201 into a dispersed stress along the circumference of the rotating rod. At the same time, the smooth curved surface design of the damping rotating rod 302 minimizes the contact wear with the positioning rope 1 and avoids the rope from breaking due to long-term friction or the foam surface from being scratched.

[0039] See Figure 1 , Figure 2 The top of the lid 202 is provided with two protrusions 207, and the bottom of the box body 201 is provided with a groove 208. Multiple foam packages 2 are spliced ​​together by the protrusions 207 and the groove 208. The protrusions 207 on the top of the lid 202 and the groove 208 on the bottom of another box body 201 are interlocked by interference fit. When multiple layers of foam packages 2 are stacked, the protrusions 207 are embedded in the grooves 208 to generate radial extrusion force, forming a vertical mechanical self-locking, which restricts the horizontal displacement of the upper box body 201 relative to the lower lid 202. At the same time, the inner wall of the groove 208 wraps around the protrusions 207 to enhance the anti-overturning ability of the stacked body, and works together with the lateral binding of the positioning rope 1 to improve the overall stability.

[0040] The implementation principle of this embodiment is as follows: First, the cover groove at the bottom of the box cover 202 is engaged with the overlapping edge 203 at the top of the box body 201, so that the box cover 202 and the box body 201 form a tight closure.

[0041] Subsequently, the protrusion 207 on the top of the box cover 202 and the groove 208 on the bottom of the other box 201 are interference-fitted to achieve vertical stacking and self-locking of multiple foam packages 2. After stacking, the two ends of the positioning rope 1 are fixed on the transport vehicle and made to pass around the damping rotating rod 302 in the two sets of protective mechanisms 3. The stacked body is then horizontally tied by tensioning the positioning rope 1.

[0042] During the binding process, the damping rod 302 rotates around the axis with the tension of the positioning rope 1, converting the concentrated compressive stress of the positioning rope 1 on the edge of the box 201 into dynamic rolling friction, while reducing the wear of the positioning rope 1 through its smooth curved surface.

[0043] Mounting base 301 is fixed in mounting groove 206 by strong adhesive 303, providing support for damping rod 302 and preventing the binding force from directly acting on the foam material and causing the edge to crush. Finally, the spherical protrusions 205 at the four corners of the cover 204 are interference-fitted with the cover 202, further enhancing the closing stability of the box and forming multiple anti-displacement protections.
