Technical Field

[0001] The utility model relates to the technical field of sponge sanding blocks, in particular to a sponge composite grid sanding block structure. Background Art

[0002] Sponge sand block is a kind of grinding tool that uses sponge as the base material and abrasives attached to its surface. It has the softness of sponge and the grinding ability of abrasives, and can be used for surface polishing, repair, grinding and removing impurities. Sponge sand block usually has good elasticity, water absorption and acid and alkali resistance, and is suitable for surface treatment of various materials such as metal, plastic, ceramic, etc. It can be used handheld or with a grinding machine, and is widely used in grinding and polishing work in furniture, automobiles, electronic products, handicrafts and other industries.

[0003] The existing patent announcement number CN217668844U discloses a composite grid sponge sanding block, including: a sponge structure, a grid structure and a protective structure. The sponge structure includes a sponge body and a support layer connected to the upper and lower ends of the sponge body, and the support layer and the sponge body are fixedly connected by a composite adhesive layer; the grid structure includes a rectangular frame fixedly connected to the outside of the support layer, the inner wall of the rectangular frame is fixedly connected to the grid layer, and the outer wall of the grid layer is fixedly connected to the sand layer; the protective structure includes a protective layer fixedly sleeved on the outer wall of the sponge body, and the protective layer is correspondingly arranged between the two supporting layers. The utility model can reduce the situation where the sand block fragments damage the workpiece when in use, and ensure the stability of friction through the design of the grid structure.

[0004] The composite grid sponge sanding block in the prior art realizes the sanding structure by setting a grid layer and a sand layer on the surface of the sponge body. However, each group of sponge bodies can be set on two sides at most. During frequent use, the sand layer will be discarded because it is worn flat, and it needs to be replaced repeatedly, which affects work efficiency. Utility Model Content

[0030] Reference Figure 1-5 The utility model provides a sponge composite grid sanding block structure, comprising:

[0031] The main unit 100 includes a sponge body 101, and both sides of the sponge body 101 are fixedly connected with a connecting piece 102;

[0032] The stacking unit 200 includes a supporting layer 201, and placement grooves 202 are opened on both sides of each group of supporting layers 201, and the inner walls of the placement grooves 202 are fixedly connected with connecting members 203, the lower side of each group of supporting layers 201 is fixedly connected with a connecting layer 204, and the surface of the connecting layer 204 is fixedly connected with a frosted layer 205, the upper and lower sides of each group of connecting members 2 203 are inclined, and two adjacent groups of connecting members 2 203 are fixedly connected.

[0033] Among them, the connection method between two adjacent groups of connecting parts 203 can be gluing, and the gluing method is polymer adhesive gluing. The polymer adhesive has excellent flexibility, heat resistance and tearing performance, so that the staff can easily separate the two groups of connecting parts 203 to facilitate the replacement of the frosted layer 205.

[0034] Furthermore, the outer side of each set of connecting members 203 is fixedly connected to a hand-pull tab 206, and the hand-pull tab 206 is made of a plastic film. The two adjacent sets of connecting members 203 can be separated by manually pinching the hand-pull tab 206 and pulling it, thereby improving practicality.

[0035] Furthermore, a storage groove is provided on the upper side of each group of support layers 201, and the size of the storage groove is consistent with the surface size of the frosted layer 205. The inner wall of each group of storage grooves is movably connected to the frosted layer 205, and the frosted layer 205 is hidden in the storage groove, which can not only protect the frosted layer 205, but also increase the stability between the two adjacent groups of connecting parts 203.

[0036] Furthermore, another connecting layer 204 is fixedly connected to the lower side of the sponge body 101, and another frosted layer 205 is fixedly connected to the surface of the frosted layer 205. The lower sides of the connecting piece 102 of both are fixedly connected to the connecting piece 203 by gluing. By removing the connecting piece 203, the frosted layer 205 on the lower side of the sponge body 101 is exposed, thereby having a frosting function.

[0037] Furthermore, each group of frosted layers 205 is made of nylon mesh, and abrasive particles are fixedly connected to the nylon mesh by gluing. The nylon mesh can support and reinforce the abrasive particles, ensure the adhesion of the abrasive particles, and also contribute to the stability of the overall block.

[0038] During use, by setting the frosted layer 205 as a nylon mesh, the nylon mesh can support and reinforce the abrasive particles, ensuring the adhesion of the abrasive particles, and also contributing to the stability of the overall block. After the frosting ability of the bottom frosted layer 205 is consumed, the hand-pull tab 206 can be manually pinched and then pulled downward. With the tearing ability of the polymer adhesive, the hand-pull tab 206 can drive the connecting piece 203 to pull downward, so that the two adjacent groups of connecting pieces 203 are separated. Then the staff can remove the bottom frosted layer 205, expose the adjacent frosted layer 205 and use it for frosting, so that each group of sponge bodies 101 can be provided with multiple groups of frosted layers 205, and there is no need to repeatedly replace the sponge body 101 during use, thereby improving practicality.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
