Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a detachable grinding structure. Background Technology

[0002] In construction, it is unavoidable to grind the inner and outer walls of pipes, or the inside and outside corners of building components. When the workload is large, power tools are generally used for grinding. When the workload is small but the distance is large, power tools are inconvenient to maneuver, and power connections are difficult in some locations. In such cases, manual grinding with sandpaper is usually performed. However, when using sandpaper, it is difficult to apply force with the hand, resulting in poor grinding results. Therefore, a grinding structure that connects to the sandpaper is designed to assist manual grinding. Utility Model Content

[0003] The purpose of this invention is to provide a detachable grinding structure.

[0004] This utility model is achieved through the following measures: a detachable grinding structure, characterized in that it includes a fixing rod, a screw rod is provided through the fixing rod, the lower end of the screw rod is connected to the middle position of the deformable rod, and sandpaper is provided on the lower end surface of the deformable rod;

[0005] The fixed rod has a lower locking block fixedly installed at both ends below, and the deformable rod has an upper locking block fixedly installed at both ends above. The upper and lower locking blocks are connected by a deformable connecting rod. The upper and lower ends of the deformable connecting rod are fixedly installed with connectors, and the connectors are provided with slots that cooperate with the lower and upper locking blocks.

[0006] An adjusting nut is provided at the upper end of the screw via a threaded connection.

[0007] Rotating the adjusting nut forward increases the length of the screw extending beyond the nut, while decreasing the length of the screw between the fixed rod and the deforming rod. With the cooperation of the deforming connecting rod, the upper locking block, and the lower locking block, the middle position of the deforming rod is pulled up by the screw, causing the deforming rod and the sandpaper to form a concave arc-shaped surface in the middle. This can be used for grinding convex arc surfaces, such as the outer wall of pipes and the external corners of building components.

[0008] Reversing the adjusting nut shortens the length of the screw extending beyond the nut, lengthens the screw between the fixed rod and the deforming rod, and pushes the middle position of the deforming rod outward, creating a convex arc-shaped surface between the deforming rod and the sandpaper. This allows for grinding of concave arc surfaces, such as the inner wall of a pipe or the inside corner of a building component.

[0009] Furthermore, the screw is mounted on the deformable rod via a connector, a boss is fixedly provided at the middle position of the deformable rod, an installation port is provided through the side of the boss, a slider is provided in the installation port, and an elongated opening communicating with the installation port is opened at the upper end of the boss, the screw extends into the elongated opening and is fixedly connected to the slider;

[0010] The slot is an arc-shaped groove that runs through the front and back and has an opening that allows the upper and lower locking blocks to engage. The opening is smaller than the width of the upper and lower locking blocks. The upper and lower locking blocks squeeze and expand the opening from the opening to enter the arc-shaped groove.

[0011] At this point, the deformable rod can detach from the slider and lower locking block in the front-to-back direction, making it convenient to replace the sandpaper. The connector, deformable rod, deformable connecting rod, slider, boss, lower locking block, and upper locking block are all made of plastic.

[0012] Furthermore, a sandpaper perforation is fixedly provided on the outer wall of the lower connector of the deformable connecting rod and above the deformable rod. The two ends of the sandpaper are folded up and pass through the sandpaper perforation and are pressed and fixed by screws.

[0013] How to use:

[0014] Depending on the grinding position, rotate the adjusting nut to deform the deforming rod, then loosen the screw that locks the sandpaper, manually press the sandpaper against the outer end face of the deforming rod, and finally tighten the screw to fix it.

[0015] The beneficial effects of the technical solution provided by this utility model embodiment are as follows: Depending on the grinding position, rotating the adjusting nut pulls the deforming rod to deform it, thereby changing the shape of the sandpaper and better adapting to the grinding position. When it is necessary to replace the sandpaper, the screws securing the sandpaper can be loosened, and then the deforming rod can be pulled forward or backward, causing the upper locking blocks at both ends of the deforming rod to disengage from the slots while the bosses disengage from the sliders. This allows the deforming rod to detach from the deforming connecting rod, facilitating the replacement of the sandpaper. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. Of course, the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0023] See Figures 1-4 A detachable grinding structure, characterized in that it includes a fixing rod 1, a screw 3 is provided through the fixing rod 1, the lower end of the screw 3 is connected to the middle position of the deformable rod 2, and a grinding sandpaper 5 is provided on the lower end surface of the deformable rod 2;

[0024] Lower locking blocks 101 are fixedly installed at the lower ends of the fixed rod 1, and upper locking blocks 201 are fixedly installed at the upper ends of the deformable rod 2. The upper locking blocks 201 and the lower locking blocks 101 are connected by a deformable connecting rod 6. Connecting heads 601 are fixedly installed at the upper and lower ends of the deformable connecting rod 6. The connecting heads 601 are provided with slots 602 that cooperate with the lower locking blocks 101 and the upper locking blocks 201.

[0025] An adjusting nut 4 is provided at the upper end of the screw 3 via a threaded connection.

[0026] Rotating the adjusting nut 4 forward increases the length of the screw 3 extending beyond the nut 4, while decreasing the length of the screw 3 between the fixed rod 1 and the deformable rod 2. With the cooperation of the deformable connecting rod 6, the upper locking block 201, and the lower locking block 101, the middle position of the deformable rod 2 is pulled up by the screw 3, causing the deformable rod 2 and the sandpaper 5 to form a concave arc-shaped surface in the middle. This can be used for grinding convex arc surfaces, such as the outer wall of pipes and the external corners of building components.

[0027] Reversing the adjusting nut 4 shortens the length of the screw 3 extending from the nut 4, lengthens the screw 3 between the fixing rod 1 and the deforming rod 2, and pushes the middle position of the deforming rod 2 outward by the screw 3, causing the deforming rod 2 and the sandpaper 5 to form a convex arc surface in the middle. This allows for the grinding of concave arc surfaces, such as the inner wall of a pipe or the inside corner of a building component.

[0028] The screw 3 is mounted on the deformable rod 2 via a connector. A boss 9 is fixedly mounted in the middle of the deformable rod 2. An installation port 901 is provided through the side of the boss 9. A slider 10 is provided inside the installation port 901. A long slot 902 communicating with the installation port 901 is opened at the upper end of the boss 9. The screw 3 extends into the long slot 902 and is fixedly connected to the slider 10.

[0029] The slot 602 is an arc-shaped groove that runs through the front and back and has an opening that allows the upper locking block 201 and the lower locking block 101 to be inserted. The opening is smaller than the width of the upper locking block 201 and the lower locking block 101. The upper locking block 201 and the lower locking block 101 squeeze and expand the opening from the opening to enter the arc-shaped groove.

[0030] At this point, the deformable rod 2 can detach from the slider 10 and the lower locking block 101 in the front-to-back direction, making it convenient to replace the sandpaper 5. The connector 601, deformable rod 2, deformable connecting rod 6, slider 10, boss 9, lower locking block 101 and upper locking block 201 are made of plastic.

[0031] A sandpaper perforation 7 is fixedly provided on the outer wall of the lower connector 601 of the deformable connecting rod 6 and above the deformable rod 2. The two ends of the sandpaper 5 are folded up and pass through the sandpaper perforation 7 and are pressed and fixed by screws 8.

[0032] How to use:

[0033] Depending on the grinding position, rotate the adjusting nut 4 to deform the deforming rod 2, then loosen the screw 8 that locks the sandpaper 5, manually make the sandpaper 5 fit tightly against the outer end face of the deforming rod 2, and finally tighten the screw 8 to fix it.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
