Description

Technical Field

[0001] This utility model relates to the field of sponge rollers, and specifically to a sponge roller with a pressing structure. 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] Existing sponge rollers lack a proper clamping structure. When using sponge rollers, a considerable amount of manual force is required to press them firmly against the surface being cleaned. However, manual force is inconvenient and cannot maintain a good, long-term fit between the sponge roller and the surface to be cleaned. As a result, the cleaning effect is not effective, or the cleaning and polishing results are reduced.

[0004] Therefore, it is necessary to invent a sponge roller with a pressing structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sponge roller with a pressing structure. When the rubber sleeve is attached to the surface of an object, multiple sets of telescopic rods inside the PVC inner tube move and extend within the limiting plate on the rear side. The springs outside the telescopic rods push the rubber sleeve back, pressing it firmly against the surface of the object. This allows the entire rubber sleeve to fit tightly against the surface being cleaned, thereby enhancing the removal of stains and moisture. This solves the problem mentioned in the background art that existing sponge rollers lack a pressing structure. When using the sponge roller, a large amount of manual force is required to press it firmly against the surface being cleaned. However, manual force is inconvenient and cannot maintain a good fit for a long time, thus failing to effectively clean the surface or reducing the effectiveness of the required processing, polishing, and stain removal.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sponge roller with a pressing structure, comprising a PVC inner tube;

[0007] A copper core is fixedly installed inside the PVC inner tube. Each PVC inner tube is equipped with a pressing mechanism for pressing the sponge roller. The pressing mechanism includes a cavity, which is opened inside the PVC inner tube. A telescopic rod is slidably connected inside the cavity. A top block is fixedly connected to the outside of the telescopic rod. A spring is sleeved below the top block and outside the telescopic rod. A fixing plate is fixedly connected above the telescopic rod.

[0008] A limiting component is installed on the upper end of a fixed plate for limiting assembly. The limiting component includes a limiting plate, and a rubber sleeve is fitted over the limiting plate.

[0009] Preferably, the telescopic rod is slidably connected to the PVC inner tube, and the telescopic rods are distributed in a ring array on the PVC inner tube.

[0010] Preferably, the telescopic rod is fixedly connected to the fixed plate, and the telescopic rod is distributed at equal intervals on the fixed plate.

[0011] Preferably, the limiting plate is fixed to the outside of the fixing plate, and threaded grooves are passed through both sides of the inside of the limiting plate. The limiting plate is threadedly connected to the fixing plate by bolts.

[0012] Preferably, the outer surface of each limiting plate is provided with a groove, and four sets of limiting plates are provided.

[0013] Preferably, the outer sides of the limiting plate are covered with adhesive cotton, the adhesive cotton is rubber cotton, and the rubber sleeve is HPVC (high degree of polymerization polyvinyl chloride).

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The pressing mechanism allows the sponge roller to fit tightly against the surface being cleaned during use, thus removing stains and moisture more effectively. After the sponge roller is installed in the required position, the rubber sleeve is attached to the surface to be cleaned. Once the rubber sleeve is attached to the surface, multiple sets of telescopic rods inside the PVC inner tube move in and out through the inner side of the rear limiting plate. The springs on the outside of the telescopic rods push the rubber sleeve back, pressing it tightly against the surface. This ensures that the entire rubber sleeve fits tightly against the surface being cleaned, thereby enhancing the effect of removing stains and moisture.

[0016] 2. By setting the limiting components, it is not only convenient to install the limiting plates, but also to enhance the limiting performance between the PVC inner tube and the limiting plates. The limiting plates are bolted through the surface of the fixing plate, so that the four sets of limiting plates are installed outside the clamping mechanism. Then, through the multiple grooves on the outside of the limiting plates and the cotton padding on both sides, the assembly performance between the limiting plates and the rubber sleeves is improved. At the same time, it also replaces the traditional glue application and avoids the occurrence of delamination. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figure 1-5 The sponge roller shown has a compression structure, including a PVC inner tube 1;

[0027] A copper core 2 is fixedly installed inside the PVC inner tube 1. A pressing mechanism 3 is provided inside the PVC inner tube 1 for pressing the sponge roller. The pressing mechanism 3 includes a cavity 301, which is opened inside the PVC inner tube 1. A telescopic rod 302 is slidably connected inside the cavity 301. A top block 303 is fixedly connected to the outside of the telescopic rod 302. A spring 304 is sleeved below the top block 303 and outside the telescopic rod 302. A fixing plate 305 is fixedly connected above the telescopic rod 302.

[0028] The limiting component 4 is installed on the upper end of the fixed plate 305 for limiting assembly. The limiting component 4 includes a limiting plate 401, and a rubber sleeve 5 is sleeved on the outside of the limiting plate 401. After the sponge roller is installed in the required position, the rubber sleeve 5 is attached to the surface to be cleaned. After the rubber sleeve 5 is attached to the surface of the object, multiple sets of telescopic rods 302 on the inner side of the limiting plate 401 move telescopically within the PVC inner tube 1. The springs 304 on the outside of the telescopic rods 302 push the rubber sleeve 5 back, so that the rubber sleeve 5 can be pressed tightly against the surface of the object. This allows the entire rubber sleeve 5 to fit tightly against the surface being cleaned, thereby enhancing the effect of removing stains and moisture.

[0029] like Figure 2 and Figure 5 As shown, the telescopic rod 302 is slidably connected to the PVC inner tube 1. The telescopic rods 302 are arranged in a ring array on the PVC inner tube 1. When the rubber sleeve 5 is subjected to pressure from the four sets of limiting plates 401 and the four sets of fixing plates 305 inside, the multiple sets of telescopic rods 302 on the rear side of the fixing plate 305 extend and retract within the PVC inner tube 1, thereby increasing the area of ​​the rubber sleeve 5 that is fully pressed.

[0030] like Figure 2 and Figure 5 As shown, the telescopic rod 302 is fixedly connected to the fixed plate 305. The telescopic rods 302 are evenly distributed on the fixed plate 305. When one rubber sleeve 5 is under pressure, it pushes the fixed plate 305, the limiting plate 401, and the multiple sets of telescopic rods 302 inside. Through the multiple sets of telescopic rods 302, the fixed plate 305 can be more balanced and stable during the telescopic process when it is under pressure.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the limiting plate 401 is fixed to the outside of the fixing plate 305. The inner sides of the limiting plate 401 are threaded grooves 402. The limiting plate 401 is threadedly connected to the fixing plate 305 by bolts 405. The limiting plate 401 is installed on the fixing plate 305 by bolts 405 on both sides, which makes it easy for workers to disassemble and replace it.

[0032] like Figure 3 and Figure 4 As shown, the outer side of the limiting plate 401 is provided with grooves 403. There are four sets of limiting plates 401. The grooves 403 on the outer side of the four sets of limiting plates 401 are closely attached to the inner side of the rubber sleeve 5, which improves the assembly between the limiting plate 401 and the rubber sleeve 5. It also replaces the traditional glue application and avoids the occurrence of glue detachment.

[0033] like Figure 3 and Figure 4As shown, the outer sides of the limiting plate 401 are covered with cotton 404, which is rubber cotton. The rubber sleeve 5 is made of HPVC (high polymer degree polyvinyl chloride). Compared with traditional cotton, the rubber sleeve 5 makes the surface smooth and prevents powder from falling off. At the same time, the rubber sleeve 5 is made of HPVC, which has stronger acid and alkali resistance and chemical resistance, and has a longer service life. This helps customers reduce overall costs and improve production yield.

[0034] The working principle of this practical application is as follows: First, four sets of limiting plates 401 are installed on the outside of the fixed plate 305 and fixed with bolts 405. Then, the rubber sleeve 5 is put on the outside of the groove 403 on the outside of the four sets of limiting plates 401, which improves the fit between the limiting plate 401 and the rubber sleeve 5 and also replaces the traditional glue application, avoiding the situation of delamination. Then, the entire sponge roller is installed in the required position, so that the rubber sleeve 5 is attached to the surface to be cleaned. When the rubber sleeve 5 is attached to the surface of the object, the rubber sleeve 5 is squeezed against the limiting plate 401 on the back side. When the limiting plate 401 is under pressure, it moves in and out of the PVC inner tube 1 through multiple sets of telescopic rods 302 on the inside. The spring 304 on the outside of the telescopic rod 302 pushes the rubber sleeve 5 back, so that the rubber sleeve 5 can be pressed tightly against the surface of the object, so that the entire rubber sleeve 5 is tightly attached to the surface being cleaned, thereby enhancing the effect of removing stains and moisture. In this way, the use process of the sponge roller with the pressing structure is completed.

[0035] 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.
