Description

Technical Field

[0001] This utility model relates to the field of sponge rollers, specifically to a corrosion-resistant and high-temperature-resistant sponge roller. Background Technology

[0002] A sponge roller is a tool made of sponge material with an abrasive coating, primarily used for polishing, grinding, cleaning, and decontamination. It typically consists of sponge, adhesive, abrasive, processing techniques, and other materials. EPDM sponge rollers, a type of tire material with a sponge-like surface, offer a variety of properties and have a wide range of applications.

[0003] A search revealed a utility model of a replaceable absorbent sponge roller with publication number CN221569192U. The roller includes a metal roller with a U-shaped frame on its outer side, the frame being rotatably connected to the end of the roller via a rotating shaft. A Z-shaped handle is welded to the surface of the U-shaped frame, and a handle sleeve is fitted onto the handle. The surface of the metal roller is covered with absorbent sponge, which magnetically attracts each other. The Z-shaped handle allows for vertical pressure application, facilitating the removal of air bubbles and improving the mounting and application of hard tissue sections. The replaceable absorbent sponge combines absorption and rolling in one operation, simplifying operation, saving experimental resources, increasing the success rate of slides, and ensuring the reliability of subsequent histopathological evaluation.

[0004] Existing sponge rollers have poor corrosion resistance and high temperature resistance. In corrosive environments, sponge rollers lacking corrosion resistance will be rapidly corroded, leading to material structure damage and performance degradation. Similarly, sponge rollers lacking high temperature resistance will deform under high temperature conditions, losing their original shape and dimensional accuracy. The replaceable absorbent sponge rollers in the above comparative case also lack corrosion resistance and high temperature resistance, resulting in the sponge being corroded and deformed under high temperatures during use.

[0005] Therefore, it is necessary to invent a corrosion-resistant and high-temperature-resistant sponge roller to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a corrosion-resistant and high-temperature-resistant sponge roller. The protective layer outside the rubber sleeve is made of polytetrafluoroethylene (PTFE), a highly chemically stable polymer material that can resist the erosion of almost all strong acids, strong alkalis, and organic solvents. Meanwhile, the rubber sleeve is made of polyurethane, which has good high-temperature resistance and excellent tolerance to acids, alkalis, and other chemicals, making it suitable for various corrosive environments. Furthermore, the rubber sleeve and inner tube are joined by grooves and protrusions to improve their bonding. The sponge covering the inner tube is made of EPDM / NBR nitrile rubber. After the sponge is ground, the rubber sleeve is applied, improving the problem of delamination. This addresses the issues raised in the background art regarding existing sponge rollers, which have poor corrosion resistance and high-temperature resistance. In corrosive environments, sponge rollers lacking corrosion resistance are rapidly corroded, leading to material structure damage and performance degradation. Similarly, sponge rollers lacking high-temperature resistance deform under high-temperature conditions, losing their original shape and dimensional accuracy.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a corrosion-resistant and high-temperature-resistant sponge roller, including a rubber sleeve;

[0008] A protective layer is provided on the outer layer of the rubber sleeve for corrosion resistance. The rubber sleeve has grooves inside. An inner tube is movably fitted inside the rubber sleeve. Protrusions are fixedly connected to the outside of the inner tube. Sponge is fitted outside the inner tube. Limit grooves are provided on the upper and lower sides inside the inner tube. Assembly components are movably fitted on both sides of the inner tube.

[0009] The mounting mechanism, located inside the assembly components, is used for installation.

[0010] Preferably, the protective layer is made of polytetrafluoroethylene, and the sleeve is made of polyurethane.

[0011] Preferably, the groove inside the rubber sleeve is movably engaged with the protrusion outside the inner tube, and the groove and protrusion are distributed in a ring array inside the protective layer and on the outside of the inner tube.

[0012] Preferably, the sponge is made of EPDM / NBR nitrile rubber, and the sponge is located between the inner tube and the rubber sleeve.

[0013] Preferably, the installation mechanism includes a telescopic rod slidably connected inside the assembly assembly. A top block is fixedly connected to the outside of the telescopic rod, an insert block is fixedly connected to the front end of the telescopic rod, a spring is fixedly provided at the front end of the telescopic rod, a docking rod is movably engaged at the front end of the telescopic rod, a slot is provided on the rear end surface of the docking rod, a first gear is fixedly connected to the front end of the docking rod, a second gear is externally meshed with the first gear, a screw is fixedly connected internally to the second gear, and a limit block is threadedly connected to the outside of the screw.

[0014] Preferably, the insert and slot are square in shape, and the telescopic rod and the connecting rod are movably engaged.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The design incorporates a rubber sleeve, protective layer, groove, inner tube, protrusion, and sponge, which not only enhances the corrosion resistance and high-temperature resistance of the rubber sleeve but also prevents it from detaching from the inner tube due to high temperatures. The outer protective layer of the rubber sleeve is made of polytetrafluoroethylene (PTFE), a highly chemically stable polymer that resists the erosion of almost all strong acids, alkalis, and organic solvents. The rubber sleeve itself is made of polyurethane, which has excellent high-temperature resistance and good tolerance to acids, alkalis, and other chemicals, making it suitable for various corrosive environments. The groove and protrusion between the rubber sleeve and the inner tube improve the bonding strength. The sponge covering the inner tube is made of EPDM / NBR nitrile rubber. After the sponge is ground and then fitted with the rubber sleeve, the problem of delamination is improved.

[0017] 2. The assembly components and installation mechanism facilitate the disassembly and replacement of the entire sponge roller. The assembly components are inserted into both ends of the inner tube. Then, the telescopic rod is pressed to insert the top block at one end into the slot at the rear end of the connecting rod. The telescopic rod is then rotated to drive the connecting rod and the first gear at the front end to rotate. When the first gear rotates, it meshes and drives the second gears on both sides and the screw to rotate. When the screw rotates, the thread pushes the limit block to move telescopically, so that the limit block is inserted into the limit groove inside the inner tube, thereby disassembling and installing the assembly components.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The illustrated corrosion-resistant and high-temperature resistant sponge roller includes a rubber sleeve 1;

[0028] The protective layer 2 is set on the outer layer of the rubber sleeve 1 for corrosion resistance. The rubber sleeve 1 has grooves 3 inside. The inner tube 4 is movably fitted inside the rubber sleeve 1. The outer side of the inner tube 4 is fixedly connected with protrusions 5. The outer side of the inner tube 4 is covered with sponge 6. The upper and lower sides of the inner tube 4 have limit grooves 7. The two sides of the inner tube 4 are movably fitted with assembly components 8.

[0029] The mounting mechanism 9, located inside the assembly component 8, is used for installation. The protective layer 2 outside the rubber sleeve 1 is made of polytetrafluoroethylene (PTFE), a highly chemically stable polymer material that can resist the erosion of almost all strong acids, strong alkalis, and organic solvents. Meanwhile, the rubber sleeve 1 is made of polyurethane (PU), which has good high-temperature resistance and good resistance to acids, alkalis, and other chemicals, making it suitable for various corrosive environments. The rubber sleeve 1 and the inner tube 4 are connected by a groove 3 and a protrusion 5 to improve their bonding. The sponge 6 covering the outside of the inner tube 4 is made of EPDM / NBR nitrile rubber. After the sponge 6 is ground, the rubber sleeve 1 is put on, which improves the problem of delamination.

[0030] like Figure 1 and Figure 2 As shown, the protective layer 2 is made of polytetrafluoroethylene (PTFE), and the sleeve 1 is made of polyurethane (PU). PTFE is a highly chemically stable polymer material that can resist the erosion of almost all strong acids, strong alkalis, and organic solvents. Meanwhile, the sleeve 1 is made of polyurethane (PU), which has good high-temperature resistance and good tolerance to acids, alkalis, and other chemicals, making it suitable for various corrosive environments.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the groove 3 inside the rubber sleeve 1 is movably engaged with the protrusion 5 outside the inner tube 4. The groove 3 and the protrusion 5 are arranged in a ring array inside the protective layer 2 and outside the inner tube 4. The rubber sleeve 1 and the inner tube 4 are connected by the groove 3 and the protrusion 5 to improve the bonding between them and avoid the situation of detachment.

[0032] like Figure 3 As shown, the sponge 6 is made of EPDM / NBR nitrile rubber. The sponge 6 is located between the inner tube 4 and the rubber sleeve 1. The sponge 6, which is made of EPDM / NBR nitrile rubber, is sleeved on the outside of the inner tube 4. When the sponge 6 is ground and then covered with the rubber sleeve 1, the problem of delamination is improved.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the installation mechanism 9 includes a telescopic rod 901, which is slidably connected inside the assembly assembly 8. A top block 902 is fixedly connected to the outside of the telescopic rod 901. An insert block 903 is fixedly connected to the front end of the telescopic rod 901. A spring 904 is fixedly installed at the front end of the telescopic rod 901. A docking rod 905 is movably engaged at the front end of the telescopic rod 901. A slot 906 is provided on the rear surface of the docking rod 905. A first gear 907 is fixedly connected to the front end of the docking rod 905. A second gear 908 is externally meshed with the first gear 907. A screw 909 is fixedly connected internally to the second gear 908. The screw 909 is externally threaded to a limiting block 910. It is inserted into the inner tube 4 through the assembly assembly 8. Then, the telescopic rod 901 is pressed to insert the top block 902 at one end into the slot 906 at the rear end of the docking rod 905. Then, the telescopic rod 901 is rotated to drive the docking rod 905 and the first gear 907 at the front end to rotate. When the first gear 907 rotates, it meshes and drives the second gears 908 on both sides and the screw 909 to rotate. When the screw 909 rotates, the thread pushes the limiting block 910 to move telescopically, so that the limiting block 910 is inserted into the limiting groove 7 inside the inner tube 4, thereby disassembling and installing the assembly assembly 8.

[0034] like Figure 4 and Figure 5 As shown, the insert 903 and slot 906 are square in shape. The telescopic rod 901 and the connecting rod 905 are movably engaged. When the telescopic rod 901 is pressed, the insert 903 at the front end of the telescopic rod 901 is inserted into the slot 906 at the rear end of the connecting rod 905, so that the telescopic rod 901 can be rotated to drive the connecting rod 905 to rotate together. The square shape of the insert 903 and slot 906 not only allows the telescopic rod 901 and the connecting rod 905 to rotate, but also prevents others from accidentally touching them and causing them to rotate.

[0035] The working principle of this practical system is as follows: First, the sponge 6 is ground on the outside of the inner tube 4. Then, the groove 3 inside the rubber sleeve 1 is fitted onto the protrusion 5 outside the inner tube 4 to form a connection, strengthening the connection between them. The protective layer 2 outside the rubber sleeve 1 is made of polytetrafluoroethylene (PTFE), a highly chemically stable polymer material that can resist the corrosion of almost all strong acids, strong alkalis, and organic solvents. At the same time, the rubber sleeve 1 is made of polyurethane (PU), which has good high-temperature resistance and good resistance to acids, alkalis, and other chemicals, making it suitable for various corrosive environments. Then, the assembly component 8 is inserted into both ends of the inner tube 4. Next, the telescopic rod 901 is pressed to allow the top block 902 at one end to insert into the slot 906 at the rear end of the connecting rod 905. Then, the telescopic rod 901 is rotated to drive the connecting rod 905. 5. The first gear 907 at the front rotates. When the first gear 907 rotates, it meshes and drives the second gears 908 and the screw 909 on both sides to rotate. When the screw 909 rotates, the thread pushes the limiting block 910 to move telescopically, so that the limiting block 910 is inserted into the limiting groove 7 inside the inner tube 4, thereby installing the assembly component 8. After the limiting is installed, the telescopic rod 901 is released. Using the spring 904 between the telescopic rod 901 and the docking rod 905, the spring pushes the telescopic rod 901 back, so that the insertion block 903 at the front end of the telescopic rod 901 leaves the slot 906 at the rear end of the docking rod 905, thereby allowing the telescopic rod 901 to extend and retract from the assembly component 8, preventing others from accidentally touching it. Finally, the entire sponge roller is installed. In this way, the use process of the corrosion-resistant and high-temperature resistant sponge roller is completed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
