Description

Technical Field

[0001] This utility model belongs to the technical field of sponge abrasive blocks, specifically relating to a sponge abrasive block that is easy to replace. Background Technology

[0002] Sponge abrasive blocks, also known as sponge sanders, mainly consist of two parts: a sponge body and abrasive particles. The sponge body is the main component of the abrasive block and is usually made of highly elastic foamed sponge. It has good elasticity and water absorption, allowing the abrasive block to easily adapt to the sanding needs of different shapes and curved surfaces. The porosity and softness of the sponge body also allow the abrasive block to closely conform to the surface being sanded, thereby improving sanding accuracy and efficiency. Simultaneously, the water absorption of the sponge body allows the abrasive block to function better in a wet state. The abrasive particles are the key component of the abrasive block, evenly distributed within the sponge body. These abrasive particles have high hardness, high wear resistance, and high cutting force, effectively removing dirt and sanding surfaces. Common types of abrasive particles include alumina, silicon carbide, and glass beads. These abrasive particles have different hardness and particle sizes, which can be selected according to specific needs.

[0003] Sponge abrasive blocks (also known as sponge sanders) are a practical grinding and polishing material. Their main characteristics are suitability for grinding curved surfaces, water absorption, and the ability to maintain wet grinding for extended periods, making them a substitute for wet sandpaper. Sponge abrasive blocks can be manufactured in various shapes and sizes, suitable for a wide range of applications. However, prolonged use can lead to wear and tear on the sponge abrasive blocks, affecting subsequent processing. Timely replacement is necessary to prepare for future work. However, the replacement process for existing sponge abrasive blocks is often cumbersome and time-consuming, leading to reduced work efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides the following technical solution: a replaceable sponge abrasive block, including a base 1, a base connecting frame 2 fixedly installed on the top of the base 1, a base connecting block 3 fixedly installed on the top of the base 1, a sponge abrasive block mounting plate 9 fixedly installed on the bottom of the base connecting frame 2, a base connecting Velcro 10 fixedly installed on the bottom of the base 1, a retaining ring 11 movably installed inside the base connecting frame 2, a retaining ring groove 12 provided on the outer side of the retaining ring 11, a drive module connecting rod 13 fixedly installed on the top of the retaining ring 11, and a drive module connecting rod 13 fixedly installed on the bottom of the drive module connecting rod 13. A slider 14 is fixedly installed on the base 1, and the inner wall of the retaining ring 11 is movably connected to the outer side of the base connecting block 3. A sponge abrasive block connecting plate 17 is movably installed on the outer side of the base 1. A sponge abrasive block 18 is fixedly installed at the bottom of the sponge abrasive block connecting plate 17. A sponge abrasive block connecting Velcro 19 is fixedly installed at the top of the sponge abrasive block 18. A sponge abrasive block fixing bolt 20 is installed in the internal thread of the sponge abrasive block connecting plate 17. There are four sets of sponge abrasive block fixing bolts 20, and the sponge abrasive block fixing bolts 20 penetrate through the interior of the sponge abrasive block mounting plate 9.

[0022] In this embodiment: the sponge abrasive block fixing bolt 20 can penetrate the sponge abrasive block mounting plate 9 and the sponge abrasive block connecting plate 17, thereby fixing the sponge abrasive block mounting plate 9 and the sponge abrasive block connecting plate 17. The base connecting Velcro 10 is connected to the sponge abrasive block connecting plate 17 fixedly installed on the top of the sponge abrasive block 18, which can prevent the middle part of the sponge abrasive block from deforming during the rotation of the sponge abrasive block. This method can improve the installation stability and replacement efficiency of the sponge abrasive block by combining two simple fixing methods.

[0023] In this embodiment: when the retaining ring connecting block 15 is engaged with the outside of the base connecting frame 2, the first spring 4 can push the first spring connecting block 5 to move outward. The outward movement of the first spring connecting block 5 can embed into the groove on one side of the retaining ring connecting block groove 16, thereby ensuring the connection stability between the base connecting frame 2 and the retaining ring connecting block 15. The second spring 6 can push the second spring connecting block 7 to move towards the center of the device, thereby pushing the connecting block 8 to move towards the center of the device. The movement of the connecting block 8 can engage the retaining ring groove 12 on the outside of the retaining ring 11, thereby further improving the connection stability between the base connecting frame 2 and the retaining ring 11. Through these two connection methods, the connection stability between the device and the external driving device can be improved, and the device replacement can be facilitated.

[0024] In this embodiment: the slider 14 can provide guidance for the rotation of the retaining ring connecting block 15, thereby facilitating the engagement of the first spring connecting block 5 and the retaining ring connecting block groove 16 on one side. By replacing the external drive module and the sponge abrasive block, different parts can be replaced according to the damage condition of the device. By replacing a single damaged part, maintenance costs can be reduced.

[0025] The working principle and usage process of this utility model are as follows: After installation, the sponge abrasive block fixing bolt 20 can pass through the sponge abrasive block mounting plate 9 and the sponge abrasive block connecting plate 17, thereby fixing the sponge abrasive block mounting plate 9 and the sponge abrasive block connecting plate 17. The base connecting Velcro 10 connects to the sponge abrasive block connecting plate 17 fixedly installed on the top of the sponge abrasive block 18, preventing deformation of the middle part of the sponge abrasive block during rotation. This method, through the combination of two simple fixing methods, improves the installation stability and replacement efficiency of the sponge abrasive block. When the retaining ring connecting block 15 is engaged with the outside of the base connecting frame 2, the first spring 4 can push the first spring connecting block 5 outward. The outward movement of the first spring connecting block 5 allows it to embed into one side of the retaining ring connecting block groove 16, thus ensuring the connection between the base connecting frame 2 and the retaining ring connecting block 15. The connection stability is improved by the second spring 6 pushing the second spring connecting block 7 towards the center of the device, which in turn pushes the connecting block 8 towards the center of the device. The movement of the connecting block 8 engages with the retaining ring groove 12 on the outer side of the retaining ring 11, thereby further improving the connection stability between the base connecting frame 2 and the retaining ring 11. The two connection methods improve the connection stability between the device and the external drive device and facilitate device replacement. The slider 14 provides guidance for the rotation of the retaining ring connecting block 15, thus facilitating the engagement of one side of the groove of the first spring connecting block 5 and the retaining ring connecting block groove 16. By replacing the external drive module and the sponge abrasive block, different components can be replaced according to the damage condition of the device. Replacing a single damaged component reduces maintenance costs. All electrical equipment in this device is powered by an external power source.
