Technical Field

[0001] The invention relates to a high-strength load-bearing foam base, belonging to the technical field of packaging boxes. Background Art

[0002] Foam packaging mainly refers to the packaging products made of expandable polystyrene (EPS) raw materials through molds and heat processing. The packaging products are commonly known as "foam". Expandable polystyrene is an ideal packaging material. Through the molding process, it can be processed into packaging products of various shapes and thicknesses according to needs. Under high load conditions, the material can achieve the effects of buffering and shock absorption through deformation, energy absorption, and energy decomposition, and also has the functions of heat preservation and heat insulation. EPS packaging products are generally white, and can be produced in color according to requirements.

[0003] Foam tray is a kind of foam packaging. Foam tray is generally used with carton to wrap and protect the upper and lower bottom surfaces of electrical equipment.

[0004] However, the existing foam base still has the following problems: first, the existing foam base is generally a flat plate, and its supporting strength is relatively limited; second, the existing foam base is generally a pure single-layer type, and its buffering ability is also relatively limited. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide a high-strength load-bearing foam base, which solves the problem of limited support strength and limited buffering capacity caused by the general use of single-layer flat foam in the prior art.

[0008] As a preferred solution of the present invention, the two second parts are provided with an assembling protrusion on one side close to the geometric center line of the first part; and the bottom surface of the first part is provided with an assembling recess for simultaneously nesting the two assembling protrusions.

[0009] As a preferred solution of the present invention, the other sides of the two second parts are each provided with a reinforcement recess, and the bottom surface of the first part is provided with a reinforcement protrusion for simultaneously cooperating with the reinforcement recess.

[0010] As a preferred solution of the present invention, a plurality of mutually parallel limiting column protrusions are provided in the reinforcing recess, and a plurality of limiting column recesses for cooperating with the limiting column protrusions are provided in the reinforcing protrusion.

[0012] As a preferred solution of the present invention, the air cushion includes an air storage depression arranged on the limiting column convexity.

[0013] As a preferred solution of the present invention, the air cushion further comprises an annular convex portion arranged in the limiting column recess, and the annular convex portion is used for sealing and nesting in the air storage recess.

[0014] As a preferred solution of the present invention, a part groove is provided on the top surface of the first part.

[0015] As a preferred solution of the present invention, both ends of the second reinforcing rib are provided with rounded corners.

[0024] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0025] like Figure 1-Figure 4 As shown, a high-strength load-bearing foam base includes a first part 1, both side edges of the first part 1 are movably provided with first reinforcing ribs 2, and both ends of the first part 1 are provided with second reinforcing ribs 3; the top surface of the first part 1 is provided with a mounting groove 4 for matching the raised part of the electrical equipment; the first reinforcing ribs 2 are connected to the second parts 5, the two second parts 5 are clamped with the bottom surface of the first part 1, and an air cushion is provided between the second part 5 and the first part 1.

[0026] In this embodiment, the two second parts 5 are provided with an assembly protrusion 6 on one side close to the geometric center line of the first part 1; the bottom surface of the first part 1 is provided with an assembly recess 7 for simultaneously nesting the two assembly protrusions 6. The other side of the two second parts 5 is provided with a reinforcement recess 8, and the bottom surface of the first part 1 is provided with a reinforcement protrusion 10 for simultaneously matching the reinforcement recess 8. In this way, the second part 5 and the first part 1 can be more tightly engaged.

[0027] In this embodiment, the reinforcing recess 8 is provided with a plurality of mutually parallel limiting column projections 11, and the reinforcing protrusion 10 is provided with a plurality of limiting column recesses 12 for matching the limiting column projections 11. The reinforcing protrusion 10 is provided with a plurality of avoidance gaps 13, and the avoidance gaps 13 are respectively provided between two adjacent limiting column recesses 12. The air cushion includes an air storage recess 14 provided on the limiting column projection 11.

[0028] As a preferred solution of the present invention, the air cushion further includes an annular protrusion 15 disposed on the limiting column recess 12 , and the annular protrusion 15 is used for sealing and nesting in the air storage recess 14 .

[0029] As a preferred solution of the present invention, the top surface of the first part 1 is provided with a parts groove 16. In this way, the parts can be stored independently to prevent the parts from damaging the equipment.

[0030] As a preferred solution of the present invention, both ends of the second reinforcing rib 3 are provided with rounded corners 9. In this way, a gap can be left in the second reinforcing rib 3, making it convenient for fingers to apply force to the second reinforcing rib 3.

[0031] The working principle is: the foam base is detachable. The advantage of being detachable is that, generally speaking, the foam base is slightly larger than or equal to the matching carton. However, after the electrical appliance is packaged and transported (generally used to install air conditioners), the foam base is difficult to be withdrawn from the carton (probably because of deformation due to pressure). At this time, the carton is usually cut directly with a knife, causing damage to the carton, making the carton unable to be reused.

[0032] Therefore, in the embodiment, when the carton is opened, the foam base is firstly extracted by extracting one of the second parts 5. The method for extracting the second part 5 is as follows: when manufacturing the second part 5, a groove (not shown in the figure) can be reserved on the outer side thereof, and force is applied through the groove, and then the second part 5 is pulled vertically upward. Since the limiting column recess 12 is elastic, the limiting column recess 12 can be deformed by reserving space by avoiding the gap 13, so that the reinforcing protrusion 10 can be separated from the limiting column recess 12, so that the second part 5 on this side is extracted. The difference between the second part 5 when being extracted and the foam directly extracted from the carton is that the second part 5 can squeeze the first part 1 when being extracted, and the elasticity of the carton is poor, so the second part 5 is easier to extract.

[0033] Then, the second part 5 on the other side is extracted according to the same steps, so that both sides of the first part 1 are evacuated, and the first part 1 can be extracted relatively easily. After the foam base is operated according to the reverse steps, the foam base can be assembled.

[0034] The present invention strengthens the structural strength of the foam base itself by setting the first reinforcing rib 2 and the second reinforcing rib 3, and the first reinforcing rib 2 and the second reinforcing rib 3 can protect the surrounding of the electrical equipment to a certain extent. Furthermore, the present invention can set an air cushion between the first part 1 and the second part 5 by splicing the first part 1 and the second part 5. The combined cushion of the air cushion and the foam has a stronger cushioning capacity than the single foam cushion.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
