Description

TECHNICAL FIELD

[0001] The utility model relates to a packing box antiskid foot pad and belongs to the technical field of packing elements. BACKGROUND

[0002] When transporting valuable items such as banknotes, vouchers and commemorative coupons, special packaging boxes are usually required to ensure safety. For example, a plastic packaging box is disclosed in Chinese Utility Model No. ZL 200920304371.3. It is composed of a box body, a lid and a lock mechanism. The locking strength is large, and the safety is good. It is a plastic packaging box with self-locking function and meets the requirements of relevant safety technical indicators, which can meet the safety technical requirements of storing and transporting valuable items.

[0003] In order to improve the stability of the packaging box during transportation, anti-skid pads are usually installed at the bottom to increase friction. However, due to the characteristics of plastic material, the packaging box may deform slightly when exposed to high or low temperature environment. This deformation may cause problems in the cooperation between the box body made of polypropylene (PP) and the anti-skid pad made of PVC material, making the anti-skid pad easy to slip off the bottom of the box. Once the anti-skid pad falls off, it will not only violate the packaging specifications of valuable securities, but also may cause the packaging box to slide and collide during transportation, increasing the risk of valuable securities scattering or packaging box damage.

[0004] In addition, if any of the four anti-skid pads at the bottom of the packaging box falls off, it will cause the bottom of the box to be uneven, which may cause poor cooperation when the lid is closed, which must be avoided. Therefore, these factors need to be considered during design and use to ensure the stability and safety of the packaging box. SUMMARY

[0005] The technical problem to be solved by the utility model lies in providing a packaging box anti-skid foot pad.

[0006] To achieve the above technical purpose, the utility model adopts the following technical scheme:

[0007] A packaging box anti-skid foot pad, comprising a fixed seat and an insert piece in close combination, wherein,

[0008] The fixed seat comprises a bottom plate and first, second, third and fourth side plates surrounding the periphery of the bottom plate, vertical grooves are respectively provided between the first, second, third and fourth side plates, so that each side plate is independent of each other, and the outer contour of the fixed seat is adapted to the inner contour of the corner compartment of the bottom of the packaging box body;

[0009] The insert piece is made of elastomer material, comprising a connecting plate and first, second, third and fourth clamping plates vertically arranged around the connecting plate; the first, second, third and fourth clamping plates are clamped on the fixing seat to connect the fixing seat and the insert piece into one body.

[0010] Horizontal grooves are formed in the first, second, third and fourth side plates respectively, and a strong demolding boss is formed in the compartment, which is located in one or more of the horizontal grooves.

[0011] Preferably, the Young's modulus of the material forming the insert piece is less than that of the material forming the fixing seat.

[0012] Preferably, the first, second, third and fourth clamping plates are made of elastomer material and respectively contact the inner side walls of the compartment.

[0013] Preferably, the material forming the fixing seat is the same as the material of the box body of the packaging box.

[0014] Preferably, the strong demolding boss is formed in the demolding process of the box body.

[0015] Preferably, the extension direction of the horizontal grooves is parallel to the bottom plate.

[0016] Preferably, the first, second, third and fourth side plates are symmetrically arranged, and the horizontal grooves arranged thereon are sequentially connected to form an annular groove.

[0017] Preferably, the outer side walls of the first, second, third and fourth side plates are respectively provided with clamping grooves extending in the vertical direction from the bottom plate, but do not intersect with the horizontal grooves.

[0018] Preferably, the first, second, third and fourth clamping plates are respectively clamped in the clamping grooves.

[0019] Preferably, the elastomer material used in the insert piece is rubber.

[0020] Compared with the prior art, the present invention achieves excellent wear resistance and effectively prevents the non-slip foot pads from falling off by using elastomeric materials to manufacture the first, second, third and fourth pallets. In addition, by designing a strong release boss to fix the non-slip foot pads of the packaging box, the need for a separate fixed foot pad is eliminated, thereby reducing production costs and simplifying the manufacturing process. The fixing seat is made of polypropylene (PP) or polyethylene (PE) material, which matches the box material, ensuring that the shrinkage rate is consistent with that of the box under different temperature conditions, ensuring a close fit in high or low temperature environments, and preventing the fixing seat from falling off.

[0025] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, the utility model discloses an anti-slip foot pad for a packaging box, which is used to be installed in the four corners of the bottom surface of the box body 100 of the packaging box or in the compartments 101 near the corners. During the manufacturing process of the box body 100, a plurality of grid-shaped compartments 101 will be formed on the bottom surface. In the demoulding process, strong demoulding bosses 102 will be formed, especially in the compartments 101 at the four corners of the bottom surface of the box body 100 or specific compartments 101 near the corners, while other compartments 101 do not include strong demoulding bosses 102. It should be noted that the strong demoulding bosses 102 are a way to implement forced demoulding. It simplifies the mold structure and is suitable for situations where the product structure is limited or a demoulding mechanism is not used. The undercuts on the product are directly demoulded, so it is easy to operate and cost-effective.

[0027] like Figure 2As shown, the package box anti-skid foot pad comprises a fixed seat 1 and an insert piece 2. The insert piece 2 is embedded in one surface of the fixed seat 1. The fixed seat 1 is made of the same material as the box body 100, which can be made of polypropylene (PP) or polyethylene (PE) material. In this way, the fixed seat 1 can maintain the same shrinkage rate as the box body 100 at extremely high or low temperatures, thereby maintaining the close fit of the fixed seat 1 with the box body 100.

[0028] In combination Figure 3 As shown, the outer contour of the fixed seat 1 is adapted to the inner contour of the compartment 102 at the corner of the bottom of the package box, so that the fixed seat 1 can be inserted and fixed into the compartment 102.

[0029] The fixed seat 1 comprises a bottom plate 10 and a first side plate 11, a second side plate 12, a third side plate 13 and a fourth side plate 14 surrounding the periphery of the bottom plate 10. Vertical grooves 16 are respectively arranged between the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14, so that each side plate is independent of each other and has a certain elasticity to facilitate insertion into the compartment 102.

[0030] The bottom plate 10 is a rectangular plate, and the surface thereof is provided with an insertion hole 101 (as shown in Figure 2 As shown, the first side plate 11 is vertically arranged at one end of the bottom plate 10. A horizontal groove 15 extending in a direction parallel to the bottom plate 10 is arranged at the middle position of the outer side wall of the first side plate 11. A clamping groove 110 extending in a vertical direction from the bottom plate 10 (perpendicular to the horizontal groove 15) but not reaching the horizontal groove 15 (the clamping groove 110 does not intersect with the horizontal groove 15) is further arranged on the outer side wall of the first side plate 11.

[0031] Similarly, the second side plate 12 is vertically arranged at one side of the bottom plate 10. A horizontal groove 15 extending in a direction parallel to the bottom plate 10 is arranged at the middle position of the outer side wall of the second side plate 12. A clamping groove 110 is arranged at the top of the outer side wall of the second side plate 12.

[0032] The third side plate 13 is arranged opposite to the first side plate 11, and the two have the same structure; the fourth side plate 14 is arranged opposite to the second side plate 12, and the two have the same structure.

[0033] The first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 are sequentially connected to each other and surround the bottom plate 10 to form a rectangular frame structure with an open end. Moreover, the horizontal grooves 15 arranged on the first side plate 11, the second side plate 12, the third side plate 13 and the fourth side plate 14 are also sequentially connected to form an annular groove. One or two of the four horizontal grooves 15 can cooperate with the upper strong relief boss 100 of the box body 100 to clamp the fixed seat 1 in the compartment 101 at the bottom of the package box.

[0034] As Figure 4As shown, the insert piece 2 includes a connecting plate 20, a first clamping plate 21, a second clamping plate 22, a third clamping plate 23, and a fourth clamping plate 24. The connecting plate 20 is a rectangular plate, which is sized to fit the bottom plate 10 of the fixing base 1. One side of the connecting plate 20 is provided with a protrusion 201, which is used to cooperate with the insertion hole 101 on the fixing base 1 to achieve the fixed fit of the connecting plate 20 and the bottom plate 10. The first clamping plate 21, the second clamping plate 22, the third clamping plate 23, and the fourth clamping plate 24 are all vertically arranged on one side of the connecting plate 20 (on the same side as the protrusion 201), which are sized to fit the clamping groove 110.

[0035] The insert piece 2 can be made of an elastic material (such as rubber), which has a Young's modulus smaller than the box body 100 and smaller than the fixing base 1. Because the smaller the Young's modulus, the greater the deformation of the material under stress, which is beneficial to improve the friction force. In use, the fixing base 1 and the insert piece 2 are connected to form a packaging box anti-skid pad. The connecting plate 20 is attached to the surface of the bottom plate 10; the first clamping plate 21, the second clamping plate 22, the third clamping plate 23, and the fourth clamping plate 24 are respectively clamped in the clamping groove 110. On the one hand, because the material forming the insert piece 2 is more elastic than the material forming the fixing base 1; on the other hand, with the structure of the first clamping plate 21, the second clamping plate 22, the third clamping plate 23, and the fourth clamping plate 24, the elasticity is better, so that the reliable connection of the insert piece 2 and the fixing base 1 can be achieved.

[0036] The packaging box anti-skid pad is inserted into the compartment 101 with the strong anti-extrusion boss 102 in the corner, which can play the anti-skid role. Because the first clamping plate 21, the second clamping plate 22, the third clamping plate 23, and the fourth clamping plate 24 are made of an elastic material, they have good wear resistance, so that the outer side wall can effectively increase the friction force when it contacts with the inner side wall of the compartment 101, thereby preventing the falling. At the same time, the bottom plate 10 also increases the friction force between the pad and the floor, thereby achieving a good anti-skid effect.

[0037] At the same time, the horizontal groove 15 on the fixing base 1 is shaped to fit the strong anti-extrusion boss 102, so that the strong anti-extrusion boss 102 is tightly fixed in the horizontal groove 15, further preventing the falling. Moreover, because the strong anti-extrusion boss 102 is formed in the process of stripping the box body 100, it is not designed separately to prevent falling, so the position of the strong anti-extrusion boss 102 is used to fix the packaging box anti-skid pad, without the need for a separate design to fix the pad, thereby reducing the cost and not increasing the process or material.

[0038] In one embodiment of the present utility model, the packaging box anti-skid foot pad can adopt a two-color injection molding process to integrally form the fixed seat and the insert piece. In this process, the main part of the fixed seat is first formed by injection molding, and then the insert piece part is formed by injection molding of the second color in the same injection molding cycle. This process ensures that the fixed seat and the insert piece are tightly combined to form an integrated structure, rather than being assembled by adhesion or other means in the later stage. Such a process not only improves production efficiency, but also ensures the structural stability and durability of the product, so that the anti-skid foot pad can be effectively fixed at the bottom of the packaging box for a long time to provide reliable anti-skid function.

[0039] It should be noted that, as shown in Figure 1 The strong escape boss 102 is only on one side or two sides of the compartment 101, not on all sides. Therefore, the packaging box anti-skid foot pad provided by the present utility model not only ingeniously utilizes the strong escape boss 102 in the compartment at the corner position, but also utilizes the symmetry (including the annular and symmetrical horizontal grooves 15) of the packaging box anti-skid foot pad, so that any packaging box anti-skid foot pad inserted into the compartment 101 in any direction can only have one side or two sides of the horizontal grooves 15 matched with the strong escape boss 102 to achieve clamping. In this way, the insertion efficiency is ensured by the symmetrical design, and the operator does not need to worry about the insertion direction being wrong.

[0040] In addition, the conventional packaging box anti-skid foot pad is made of polyvinyl chloride (PVC) material, which can become hard and shrink in winter, and is more likely to fall off the box body. The fixed seat of the packaging box anti-skid foot pad provided by the present utility model is made of polypropylene (PP) or polyethylene (PE) material, which matches the material of the box body, ensures consistent shrinkage rate with the box body under different temperature conditions, and ensures tight fit in high temperature or low temperature environment to prevent the fixed seat from falling off.

[0041] The packaging box anti-skid foot pad provided by the present utility model has been described in detail above. For those skilled in the art, any obvious modification made to it without departing from the essential content of the present utility model will constitute an infringement of the patent right of the present utility model, and will bear corresponding legal responsibility.
