Description

Technical Field

[0001] This utility model relates to the field of sponge technology, specifically to a plug-in large sponge structure. Background Technology

[0002] A sponge is a porous material with excellent water absorption, used for cleaning. Commonly used sponges are made from wood cellulose fibers or foamed plastic polymers. There are also natural sponges made from sponge animals, most of which are used for body cleaning or painting. Additionally, there are three other types of synthetic sponges made from materials such as low-density polyether (non-absorbent), polyvinyl alcohol (highly absorbent with no obvious pores), and polyester.

[0003] Sponges have a wide range of applications. Large sponges are generally used in furniture and large toys, and the length of a large sponge after molding can reach tens of meters. Currently, large sponges are generally shipped as a whole, and then cut by the customer according to their needs. However, sometimes, depending on the actual situation, customers will hollow out the inner core of the sponge, separating the inner core from the outer sponge and processing them separately. This method requires customers to have large wire cutting machines, which is inconvenient. Therefore, in most cases, they are transported separately. However, if they are directly inserted, the inner core sponge is prone to leaking out from the outer sponge during bumpy transportation. Therefore, there is an urgent need for an improved technology to solve this problem existing in the current technology. Utility Model Content

[0004] The purpose of this invention is to provide a pluggable large sponge structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pluggable large sponge structure, comprising an outer sponge body, an inner sponge body, and a limiting sponge body. The outer sponge body has a long, narrow cavity extending through it along its length. The outer sponge body has slots at both ends of the long, narrow cavity and extending outward along its cross-section. The inner sponge body is inserted into the long, narrow cavity of the outer sponge body. There are two limiting sponge bodies, each located in a slot at one end of the long, narrow cavity.

[0006] Preferably, in the plug-in large sponge structure provided by this utility model, the distance from the slot to the corresponding end face of the outer sponge body is at least 10cm.

[0007] Preferably, in the plug-in large sponge structure provided by this utility model, the length of the inner sponge body is not greater than the distance between the two limiting sponge bodies.

[0008] Preferably, in the plug-in large sponge structure provided by this utility model, the height and width of the inner sponge body are not greater than the height and width of the elongated cavity.

[0009] Preferably, the plug-in large sponge structure provided by this utility model has the length, width, and height of the limiting sponge body consistent with the length, width, and height of the corresponding slot.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) The outer sponge has a long strip cavity running through it along the length direction. During transport, the inner sponge can be inserted into the long strip cavity of the outer sponge, eliminating the need for separate transport. This greatly improves convenience and reduces transport costs. In special circumstances, the outer sponge can be thinner as a protective layer to better protect the inner sponge and prevent contamination.

[0012] (2) Since the outer and inner sponge bodies have been separated, the difficulty and steps of subsequent processing are reduced.

[0013] (3) The long, narrow cavity has slots at both ends, and a limiting sponge is provided at the slot to ensure that the inner sponge will not detach from the outer sponge during transportation. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that in the description of this utility model, the terms "inner", "outer", "upper", "lower", "both sides", "one end", "the other end", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a pluggable large sponge structure, including an outer sponge body 1, an inner sponge body 2, and a limiting sponge body 3. An elongated cavity 4 is formed through the outer sponge body 1 along its length. Slots 5 are formed at both ends of the outer sponge body 1 and extend outwards along its cross-section. The distance from the slot 5 to the corresponding end face of the outer sponge body 1 is at least 10cm to ensure the support of the outer sponge body 1 located outside the slot 5. The inner sponge body 2 is inserted into the elongated cavity 4 of the outer sponge body 1, and the length of the inner sponge body 2 is not large. The distance between the two limiting sponge bodies 3 is such that the limiting sponge body 3 can be smoothly installed in the slot 5. The height and width of the inner sponge body 2 are not greater than the height and width of the elongated cavity 4, so as to ensure that the inner sponge body 2 can be smoothly inserted into the outer sponge body 1. The size of the elongated cavity 4 and the size of the inner sponge body 2 are set according to the requirements. There are two limiting sponge bodies 3, which are respectively set in the slots 5 at both ends of the elongated cavity 4. The length, width and height of the limiting sponge body 3 are consistent with the length, width and height of the corresponding slot 5, so as to ensure the stability of the limiting sponge body 3 after it is inserted into the slot 5 and prevent it from easily falling off.

[0022] Usage and Principle: First, the outer sponge 1, inner sponge 2, and limiting sponge 3 are produced through a foaming process. Next, grooves 5 are cut into the inner wall of the elongated cavity 4 of the outer sponge 1 using a cutting machine or a high-temperature hot-melt mechanism. A distance of at least 10cm is left between the grooves 5 and the end of the outer sponge 1. Then, the inner sponge 2 is inserted into the elongated cavity 4 of the outer sponge 1, ensuring that the length of the inner sponge 2 does not exceed the distance between the two grooves 5. Next, the limiting sponge 3 is curled and deformed and inserted into the elongated cavity 4, then released, and the outer edge of the limiting sponge 3 is inserted into the groove 5, completing the assembly. When transported via a conveyor or in a container, the inner sponge 2 is located within the outer sponge 1. This utility model has a reasonable structure. The outer sponge body 1 has a long, narrow cavity 4 extending through it along its length. During transport, the inner sponge body 2 can be inserted into the long, narrow cavity 4 of the outer sponge body 1, eliminating the need for separate transport, greatly improving convenience and reducing transportation costs. In special circumstances, the outer sponge body 1 can be thinner to act as a protective layer, thus better protecting the inner sponge body 2 from contamination. Since the outer sponge body 1 and the inner sponge body 2 are separated, the difficulty and steps of subsequent processing are reduced. At the same time, slots 5 are provided at both ends of the long, narrow cavity 4, and limiting sponge bodies 3 are provided at the slots 5 to ensure that the inner sponge body 2 will not detach from the outer sponge body 1 during transport.

[0023] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.
