Description

Technical Field

[0001] This utility model relates to the field of foam base technology, and in particular to a foam base. Background Technology

[0002] A foam base is a functional component made primarily of foam that supports, positions, and protects items. By wrapping and securing items circumferentially, the foam base prevents items from shaking or shifting during transportation, storage, or use, thus ensuring the stability and safety of the items.

[0003] However, when using foam bases to transport items, the foam base is usually tightly wrapped around the bottom of the item, which can provide effective protection. However, most common foam bases are a single piece, and because they are wrapped too tightly, it is difficult to remove items from the foam base or put items into the foam base. Forcibly removing items is not only time-consuming and laborious, but may also cause deformation or damage to the foam components due to excessive pulling, and may even cause scratches or bumps to the item itself. Therefore, this application proposes a foam base. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foam base to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foam base, comprising:

[0006] The seat body is designed as a rectangular structure, with an integrated upper baffle installed at the top edge of the seat body and an integrated lower baffle installed at the bottom edge of the seat body.

[0007] There are four sets of support blocks. The support blocks are L-shaped and are installed at the four corners of the inner wall of the upper enclosure in an inclined manner.

[0008] There are four sets of fastening plates. The fastening plates are long and plate-shaped, and the four fastening plates are respectively fitted between each pair of adjacent support blocks.

[0009] The sleeve is set on the top of the base and pressed on the support block and fastening plate. Two symmetrically distributed slots are opened on each of the four sides of the top of the sleeve.

[0010] The base plate is detachably mounted on the top of the seat and is located between four support blocks. Four fastening plates abut against the four sides of the base plate.

[0011] Optionally, the top of the support block is lower than the top of the upper enclosure. The top of each of the four support blocks is provided with an L-shaped connecting groove similar in shape. The bottom of the sleeve is provided with an integrated lower convex plate, and L-shaped connecting blocks that match the shape of the connecting groove are fixedly installed at the four corners of the bottom of the lower convex plate.

[0012] Optionally, the thickness of the lower convex plate is the same as the distance between the top of the support block and the top of the upper enclosure, and the inner wall of the lower convex plate is flush with the inner walls of the four support blocks, with the connecting block and the expansion joint inserted into the connecting groove.

[0013] Optionally, both ends of each support block are set as inner inclined surfaces, the cross section of the fastening plate is an isosceles trapezoid, and both ends of the fastening plate are respectively attached to the inner inclined surfaces of the corresponding support block ends. The thickness and height of the fastening plate are the same as the thickness and height of the support block.

[0014] Optionally, a first notch is provided at the center of each of the four sides of the upper enclosure, a first groove is provided on the outer side of each of the four fastening plates corresponding to the position of the first notch, a second groove is provided on the inner side of each of the four fastening plates corresponding to the position of the first notch, and two symmetrically distributed second notches are provided on each of the four sides of the lower enclosure.

[0015] Optionally, an integrated support assembly is installed at the bottom of the seat and between the lower enclosure. The support assembly consists of a support ring and support plates. The support ring is installed at the bottom of the seat. Eight support plates are connected in a circular array through the side wall of the support ring. The side wall of the support ring has a first notch that is the same number as the support plates and is staggered in a circular array. The height of the support assembly is the same as the height of the lower enclosure.

[0016] Optionally, a through-hole is provided at the center of the top of the base. The base plate includes a plate and a ring. The plate is placed on top of the base and between four support blocks. The ring is fixedly installed at the bottom of the plate and inserted into the through-hole. A cross-shaped support frame is fixedly installed between the rings. The top of the plate and the part between the rings has through holes in a circular array, the same number as the first notch. The bottom of the side wall of the ring has a second notch in a circular array, the same number as the first notch.

[0017] The beneficial effects of this utility model are:

[0018] This foam base solves the problem of difficulty in placing and removing items caused by the tight wrapping of traditional one-piece foam bases, thanks to its interlocking fastening plate and sleeve structure. (The larger contact area between the object and the one-piece foam base increases the friction between them, making it difficult to place or remove items.) The fastening plate can be easily removed through the first notch in the upper enclosure, and the connection structure between the sleeve and the support block also facilitates quick separation, reducing resistance when forcibly removing items, avoiding the risk of deformation or damage to the foam components and scratching of items, and improving ease of operation.

[0019] The L-shaped support block and the isosceles trapezoidal fastening plate fit together to form a four-way enclosure of the base plate. The fastening plate is pressed against the side of the base plate to fix its position. When the base plate is not needed, it can be removed. The sleeve is precisely connected to the support block through the lower convex plate and connecting block, further pressing the support block and fastening plate to ensure that the overall structure is not easy to loosen during transportation or storage, and effectively prevents the items from shaking or shifting.

[0034] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0035] Please see Figures 1-7 This utility model provides a technical solution: a foam base, including a base body 1, which is a rectangular structure. An integrated upper baffle is installed at the top edge of the base body 1, and an integrated lower baffle is installed at the bottom edge of the base body 1. Support blocks 11 are fixedly installed at the four corners of the top of the base body 1 and located on the inner wall of the upper baffle. The support blocks 11 are L-shaped, and a long plate-shaped fastening plate 2 is embedded between each two adjacent support blocks 11. A sleeve 3 is provided on the top of the base body 1, and the sleeve 3 presses against the support blocks 11 and the fastening plate. Above 2, two symmetrically distributed slots 33 are opened on each of the four sides of the top of the sleeve 3. The base plate 4 is detachably installed on the top of the seat 1 and between the four support blocks 11. The four fastening plates 2 are respectively abutted against the four sides of the base plate 4. The rectangular seat 1, together with the upper and lower enclosures, forms a basic frame. The L-shaped support blocks 11 and the long plate-shaped fastening plates 2 are combined to enclose and fix the base plate 4. The sleeve 3 is pressed to enhance the overall stability. The detachable design of the base plate 4 facilitates the transportation of different items. The overall structure takes into account both protection and ease of operation.

[0036] like Figure 2 and Figure 3 As shown, the top of the support block 11 is lower than the top of the upper enclosure. The top of each of the four support blocks 11 is provided with an L-shaped connecting groove 111 similar in shape. The bottom of the sleeve 3 is provided with an integral lower convex plate 31, and L-shaped connecting blocks 32 that are adapted to the shape of the connecting groove 111 are fixedly installed at the four corners of the bottom of the lower convex plate 31. The connecting groove 111 on the top of the support block 11 and the connecting block 32 on the lower convex plate 31 at the bottom of the sleeve 3 are adapted to form a precisely positioned fitting structure, ensuring that the sleeve 3 is not easy to shift after installation. The design that the height of the support block 11 is lower than that of the upper enclosure provides installation space for the sleeve 3, making the connection between the sleeve 3 and the base 1 tighter and improving the stability of the overall structure.

[0037] like Figure 2 and Figure 7 As shown, the thickness of the lower convex plate 31 is the same as the distance between the top of the support block 11 and the top of the upper enclosure, ensuring that after the sleeve 3 is installed, the lower convex plate 31 at its bottom fits tightly with the top of the support block 11 and the fastening plate 2, avoiding loose connections. The inner wall of the lower convex plate 31 is flush with the inner walls of the four support blocks 11. The connecting block 32 and the expansion joint are inserted into the connecting groove 111, ensuring a regular enclosure space for internal items, reducing swaying caused by gaps, and enhancing the protective effect. The expansion joint of the connecting block 32 and the connecting groove 111 makes the connection between the sleeve 3 and the base 1 difficult to separate.

[0038] like Figure 3 and Figure 6 As shown, both ends of each support block 11 are set as inner inclined surfaces. The cross-section of the fastening plate 2 is an isosceles trapezoid, and both ends of the fastening plate 2 are respectively attached to the inner inclined surfaces of the corresponding support block 11 ends. The thickness and height of the fastening plate 2 are the same as those of the support block 11. The inner inclined surfaces at both ends of the support block 11 are seamlessly connected to the two ends of the fastening plate 2, which improves the tightness of the fit between the support block 11 and the fastening plate 2. The thickness and height of the fastening plate 2 are the same as those of the support block 11, ensuring that the top of both is flat, which facilitates the stable pressing of the sleeve 3, and at the same time enhances the four-way fastening force on the base plate 4 to prevent the item from shifting.

[0039] like Figure 1 , Figure 2 and Figure 6 As shown, a first notch 13 is provided at the center of each of the four sides of the upper enclosure. A first groove 21 is provided on the outer side of each of the four fastening plates 2 corresponding to the first notch 13. A second groove 22 is provided on the inner side of each of the four fastening plates 2 corresponding to the first notch 13. Two symmetrically distributed second notches 14 are provided on each of the four sides of the lower enclosure, which enhances the ease of operation and adaptability of the structure. The first notch 13 of the upper enclosure corresponds to the first groove 21 of the fastening plate 2, making it easy to insert fingers to remove the fastening plate 2. The second groove 22 on the inner side of the fastening plate 2 makes it easy to remove the fastening plate 2 when the base is located inside the carton. The second notch 14 of the lower enclosure makes it easy to grab the base during handling, or to use with external fasteners (such as straps to bind it through the second notch 14) to enhance the stability during transportation.

[0040] like Figure 4 As shown, an integrated support component 15 is installed at the bottom of the seat 1 and between the lower enclosure. The support component 15 consists of a support ring and support plates. The support ring is installed at the bottom of the seat 1. Eight support plates are connected in a circular array through the side wall of the support ring. The side wall of the support ring has a first notch in a circular array, which is the same number as the number of support plates and is distributed in an alternating pattern. The height of the support component 15 is the same as the height of the lower enclosure, which optimizes the load-bearing capacity and lightweight design of the base. The support component 15 is at the same height as the lower enclosure, which ensures that the seat 1 is placed stably and improves the load-bearing strength of the bottom. The circular array of support plates and the alternating first notches, together with the circular holes 12 at the bottom of the seat 1, allow water and other substances that enter the top of the seat 1 to drain smoothly, avoiding the accumulation of water stains on the top of the seat 1.

[0041] like Figure 2 and Figure 5As shown, a through-hole 12 is provided at the center of the top of the base 1. The base plate 4 includes a plate 41 and a ring 42. The plate 41 is placed on top of the base 1 and located between four support blocks 11. The ring 42 is fixedly installed at the bottom of the plate 41 and inserted into the through-hole 12. A cross-shaped support frame 43 is fixedly installed between the rings 42. The top of the plate 41 and the part located between the rings 42 has through holes 44 in a circular array, the same number as the first notch. The bottom of the side wall of the ring 42 has a second notch 45 in a circular array, the same number as the first notch. The base plate 4 is detachable by inserting the ring 42 into the through-hole 12 at the center of the base 1, which facilitates the transportation of different items. The cross-shaped support frame 43 enhances the deformation resistance of the base plate 4 and is suitable for bearing heavy objects. The through holes 44 of the plate 41 and the second notch 45 of the ring 42 also have the function of drainage and have a certain degree of air permeability.

[0042] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
