Description

Technical Field

[0001] This application relates to the technical field of sponge sand, and in particular to a type of stacked sponge sand. Background Technology

[0002] Sponge grinding blocks, also known as sponge sanding blocks, polishing blocks, resin grinding blocks, abrasive grinding blocks, plastic grinding blocks, etc., are made of sponge as the base, with abrasive sand embedded on the sponge. The sponge base is absorbent, so it can be wet-polished and can be bent, thus it is widely used.

[0003] The existing announcement number is CN219465921U, entitled "A Kind of Stacked Sponge Sand," which includes a sponge base layer, an adhesive layer fixedly installed on the top of the sponge base layer, a mesh layer filled inside the adhesive layer, a substrate fixedly installed inside the adhesive layer, a frosted layer fixedly installed on the top of the substrate, an extension rod fixedly installed on the bottom of the substrate, and barbs fixedly installed on the outside of the extension rod. The stacked sponge sand is bonded to the substrate and the sponge base layer together through the adhesive layer. At the same time, the extension rod at the bottom of the substrate is also inserted into the sponge base layer. One set of barbs on the outside of the extension rod is located below the mesh layer, and another set is located inside the sponge base layer. Once the adhesive layer cures, the sponge base layer and the substrate will be tightly connected together, thereby achieving the purpose of a firm connection between the sponge base layer and the frosted layer.

[0004] Regarding the aforementioned technologies, the inventors discovered that the frosted layer uses barbed rods inserted into the sponge sand block to anchor and stabilize the frosted layer. However, the frosted layer is supported by a substrate, but the sponge substrate is relatively soft, and the sponge substrate deforms when subjected to friction. The sponge substrate lacks limiting support components, which is not conducive to the frosted layer being subjected to concentrated force for polishing. Utility Model Content

[0005] In order to overcome the problems of existing frosted layers using substrate support, but the sponge base layer is relatively soft and deforms under force and friction, and the sponge base layer lacks limiting support, which is not conducive to the concentrated force of the frosted layer for grinding, this application provides a stacked sponge sand.

[0006] The technical solution for a type of stacked sponge sand provided in this application is as follows: A type of stacked sponge sand includes a top plate, a sponge base block, and a frosted component. A through groove is formed in the center of the top plate, and the sponge base block is positioned on the bottom surface of the top plate. A through groove is formed in the center of the sponge base block, and a groove is horizontally formed on the bottom surface of the sponge base block. The frosted component is positioned below the sponge base block and includes a holding member, a pressure plate, and a frosted layer. The holding member is positioned on the bottom surface of the sponge base block and includes a retaining frame inserted into the groove on the bottom surface of the sponge base block. A perforated plate is vertically fixed on the top surface of the retaining frame, vertically penetrating the through groove in the sponge base block and the through groove in the top plate. A hole seat is vertically fixed on the top surface of the top plate, and a rod is horizontally inserted through the hole seat, with one end of the rod inserted into the perforated plate. The pressure plate is fixed to the bottom surface of the holding member, and a frosted layer is fixed on the bottom surface of the pressure plate.

[0007] By adopting the above technical solution, the abrasive part is set on the bottom surface of the sponge base. The perforated plate on the top surface of the pressure holder on the abrasive part vertically penetrates the through groove of the sponge base. Pulling the insertion rod on the hole seat moves and compresses the spring deformation. Then, the top plate is set on the top surface of the sponge base. The top of the perforated plate penetrates the through groove on the top plate. Releasing the insertion rod, under the action of the spring deformation force, pushes the insertion rod into the perforated plate, thus completing the assembly of the top plate, the sponge base and the abrasive part. The abrasive layer on the pressure holder is used for grinding. Thus, the sponge base is assembled with the abrasive part through the top plate, ensuring the deformation and extrusion stability of the sponge base and facilitating the uniform force on the abrasive part for grinding.

[0008] Optionally, a spring is horizontally sleeved on the outside of the insertion rod, and the two ends of the spring are fixed to the end of the insertion rod and the hole seat, respectively.

[0009] By adopting the above technical solution, the insertion rod on the hole seat is moved and the spring is deformed during use. When the insertion rod is released, it is pushed into the hole plate under the action of the spring deformation force, thereby completing the assembly of the top plate, the sponge base block and the frosted part.

[0010] Optionally, two tie rods are symmetrically arranged on the top surface of the top plate, and the bottom ends of the two tie rods are fixed to the top surface of the top plate.

[0011] By adopting the above technical solution, the puller on the top plate makes it easy to hold the workpiece with both hands and press it down to perform grinding.

[0012] Optionally, a base plate is horizontally arranged on the bottom surface of the card frame, and a slider is horizontally fixed on the top surface of the base plate.

[0013] By adopting the above technical solution, the card frame and the substrate are assembled in the card frame by sliding the slider, which facilitates the subsequent disassembly, assembly and replacement of the substrate.

[0014] Optionally, the slide bar of the substrate is horizontally slidably assembled in the card frame, and multiple elastic frames are horizontally and vertically fixed on the bottom surface of the substrate.

[0015] By adopting the above technical solution, the slide bar of the substrate slides in the frame, which makes it easy to replace the frosted layer with different friction coefficients. The elastic frame on the substrate makes it easy to elastically support the downward pressure of the frosted layer for polishing.

[0016] Optionally, a retaining tube is vertically fixed through the bottom surface of the elastic frame, and a retaining groove is vertically opened on the inner wall of the retaining tube.

[0017] By adopting the above technical solution, the clamps on the elastic frame are used to assemble and connect the pressure plate.

[0018] Optionally, a locking post is vertically fixed on the top surface of the pressure plate, and a locking strip is vertically fixed on the outer circumference of the locking post. The locking post is inserted into the locking cylinder, and the locking strip on the locking post is inserted into the locking groove of the locking cylinder.

[0019] By adopting the above technical solution, the locking pin on the pressure plate is inserted into the locking cylinder, thus limiting the connection between the pressure plate and the base plate.

[0020] Optionally, multiple elastic bands are fixed horizontally and vertically on the frosted layer, and these elastic bands are sleeved on the pressure plate.

[0021] By adopting the above technical solution, the frosted layer is fitted onto the pressure plate using multiple elastic bands, which facilitates the quick installation of the frosted layer onto the pressure plate.

[0022] In summary, this application includes at least one of the following beneficial technical effects: During use, the abrasive part is set on the bottom surface of the sponge base block. The perforated plate on the top surface of the pressure holder on the abrasive part vertically penetrates the through groove of the sponge base block. Pulling the insertion rod on the hole seat moves and compresses the spring deformation. Then, the top plate is set on the top surface of the sponge base block. The top of the perforated plate penetrates the through groove on the top plate. Releasing the insertion rod, under the action of the spring deformation force, pushes the insertion rod into the perforated plate, thus completing the assembly of the top plate, the sponge base block, and the abrasive part. The abrasive layer on the pressure holder in use is used for grinding. Thus, the sponge base block is assembled with the abrasive part through the top plate, ensuring the deformation and compression stability of the sponge base block and facilitating uniform force distribution on the abrasive part for grinding.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a type of stacked sponge sand. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 A type of stacked sponge sand includes a top plate 1, a sponge base block 2, and a frosted component 3. A through groove 11 is formed through the center of the top plate 1, and the sponge base block 2 is disposed on the bottom surface of the top plate 1. A through groove is formed through the center of the sponge base block 2, and a horizontal groove is formed on the bottom surface of the sponge base block 2. The frosted component 3 is disposed below the sponge base block 2 and includes a holding member 31, a pressure plate 32, and a frosted layer 34. The holding member 31 is disposed on the bottom surface of the sponge base block 2 and includes a retaining frame. 311, the card frame 311 is inserted into the groove on the bottom surface of the sponge base block 2, and a perforated plate 312 is vertically fixed on the top surface of the card frame 311. The perforated plate 312 is vertically set through the through groove of the sponge base block 2 and the through groove 11 on the top plate 1. A hole seat 12 is vertically fixed on the top surface of the top plate 1, and a plug rod 13 is horizontally inserted through the hole seat 12. One end of the plug rod 13 is inserted into the perforated plate 312. The pressure plate 32 is fixed on the bottom surface of the pressure holder 31, and a frosted layer 34 is fixed on the bottom surface of the pressure plate 32.

[0028] By adopting the above technical solution, the abrasive part 3 is set on the bottom surface of the sponge base 2. The perforated plate 312 on the top surface of the pressure holding member 31 on the abrasive part 3 vertically penetrates the through groove of the sponge base 2. The insertion rod 13 on the hole seat 12 is pulled to move and compress the deformation of the spring 14. Then, the top plate 1 is set on the top surface of the sponge base 2. Then, the top of the perforated plate 312 penetrates the through groove 11 on the top plate 1. The insertion rod 13 is released and pushed into the perforated plate 312 under the deformation force of the spring 14. Thus, the assembly of the top plate 1, the sponge base 2 and the abrasive part 3 is completed. The abrasive layer 34 on the pressure holding member 31 is used to press and polish the sponge base 2. Thus, the sponge base 2 is assembled with the abrasive part 3 through the top plate 1, ensuring the deformation and compression stability of the sponge base 2 and facilitating the uniform force on the abrasive part 3 for polishing.

[0029] Reference Figure 5A spring 14 is horizontally sleeved on the outside of the insertion rod 13, and the two ends of the spring 14 are fixed to the end of the insertion rod 13 and the hole seat 12, respectively. In use, pulling the insertion rod 13 on the hole seat 12 moves it and compresses the spring 14 to deform. When the insertion rod 13 is released, under the action of the deformation force of the spring 14, the insertion rod 13 is pushed into the hole plate 312, thereby completing the assembly of the top plate 1, the sponge base block 2 and the frosted part 3.

[0030] Reference Figure 5 Two pull brackets 15 are symmetrically arranged on the top surface of the top plate 1, and the bottom ends of the two pull brackets 15 are fixed to the top surface of the top plate 1. The pull brackets 15 on the top plate 1 facilitate the grinding of the workpiece by pressing down with both hands.

[0031] Reference Figure 3 and Figure 4 A base plate 313 is horizontally mounted on the bottom surface of the card frame 311, and a slider 314 is horizontally fixed on the top surface of the base plate 313. The card frame 311 and the base plate 313 are slidably assembled in the card frame 311 via the slider 314, facilitating later disassembly, assembly, and replacement of the base plate 313. The slider 314 of the base plate 313 is horizontally slidably assembled in the card frame 311, and multiple elastic frames 315 are horizontally and vertically fixed on the bottom surface of the base plate 313. The slider 314 of the base plate 313 slides in the card frame 311, facilitating the replacement of the abrasive layer 34 with different friction coefficients. The elastic frames 315 on the base plate 313 provide elastic support for pressing down the abrasive layer 34 for polishing.

[0032] Reference Figure 3 and Figure 4 A retaining sleeve 316 is vertically fixed through the bottom surface of the elastic frame 315, and a retaining groove is vertically formed on the inner wall of the retaining sleeve 316. The retaining sleeve 316 on the elastic frame 315 is used to assemble and connect the pressure plate 32. A retaining post 33 is vertically fixed on the top surface of the pressure plate 32, and a retaining strip is vertically fixed on the outer circumference of the retaining post 33. The retaining post 33 is inserted into the retaining sleeve 316, and the retaining strip on the retaining post 33 is inserted into the retaining groove of the retaining sleeve 316. The retaining post 33 on the pressure plate 32 is inserted into the retaining sleeve 316, limiting the connection between the pressure plate 32 and the base plate 313. Multiple elastic bands 35 are horizontally and vertically fixed on the frosted layer 34, and the multiple elastic bands 35 are sleeved on the pressure plate 32. The frosted layer 34 is sleeved on the pressure plate 32 by the multiple elastic bands 35, thereby facilitating the quick installation of the frosted layer 34 on the pressure plate 32.

[0033] The implementation principle of the stacked sponge sand in this application embodiment is as follows: the abrasive part 3 is set on the bottom surface of the sponge base block 2, and the perforated plate 312 on the top surface of the pressure holding member 31 on the abrasive part 3 vertically penetrates the through groove of the sponge base block 2. The insertion rod 13 on the hole seat 12 is pulled to move and compress the spring 14 to deform. Then the top plate 1 is set on the top surface of the sponge base block 2. Then the top of the perforated plate 312 penetrates the through groove 11 on the top plate 1. The insertion rod 13 is released and pushed into the perforated plate 312 under the deformation force of the spring 14, thereby completing the assembly of the top plate 1, the sponge base block 2 and the abrasive part 3. The abrasive layer 34 on the pressure holding member 31 is used to press and polish.
