Abstract
Description
Technical Field
[0001] The utility model provides a sand block holder and belongs to the technical field of sand block auxiliary devices. Background Art
[0002] Sand block, also known as sponge sand block, is a kind of grinding and polishing material with sponge as the base and abrasive sand planted on the sponge. It is widely used in grinding and polishing the rough surface of solid wood furniture, wall decoration, profiles, steel structures and other materials.
[0003] When using the existing sand block, the staff usually directly pinches the two side walls of the sand block, and then prevents the sand block from constantly moving on the surface of the material to be polished. However, in the process of moving, it is easy to produce hand sweat, and the hands will inevitably become loose during the movement, and then the fingers will move downward and rub against the surface of the polished material, causing injuries to the fingers. The severe pain when the fingers are injured will also cause the staff to loosen the sand block and make it fall. Based on this, the utility model provides a sand block clamp. Utility Model Content
[0004] The technical problem solved by the utility model is that the fingers are easily injured by the traditional direct use of sand blocks for grinding, and the pain caused by the sand blocks may cause the workers to loosen the sand blocks and make them fall.
[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a sand block clamp, including a clamping seat, a handle is provided on the top of the clamping seat, the handle is a T-shaped structure with a larger upper part and a smaller lower part, a placement groove is provided at the bottom of the clamping seat, and inverted hooks are provided on the inner side walls around the placement groove.
[0006] Furthermore, matching sand blocks are placed in the placement groove.
[0007] Furthermore, the outer walls on both sides of the handle are concave arc surfaces, and the four corners of the top of the handle are rounded.
[0008] Furthermore, the clamping seat and the handle are both made of plastic.
[0009] Beneficial effects of the utility model:
[0010] The sand block is squeezed into the placement slot. The staff covers the handle with their palms and presses their fingers on the concave arc surfaces of the outer walls on both sides of the handle. This is ergonomic, more secure and comfortable to hold, effectively preventing the block from falling and preventing fingers from being injured during sanding, and has a good effect.

[0016] The utility model is further described below in conjunction with the accompanying drawings.
[0017] According to the attached Figure 1 , 3 As shown in Figure 4: The utility model provides a sand block clamp: it includes a clamping seat 1, a placement groove 3 is provided at the bottom of the clamping seat 1, and the inner side walls around the placement groove 3 are provided with inverted hooks 4, and a matching sand block 5 is placed in the placement groove 3. Since the sand block 5 itself has a certain elasticity, the sand block 5 is pressed into the placement groove 3 with force, so that the outer wall of the sand block 5 fits with the inner wall of the placement groove 3, and the inverted hook 4 can squeeze and limit the sand block 5, effectively preventing the sand block 5 from falling from the placement groove 3.
[0018] According to the attached Figure 1 , 2 As shown in 4: a handle 2 is provided on the top of the clamping seat 1. The handle 2 is a T-shaped structure with a larger upper part and a smaller lower part. The outer walls on both sides of the handle 2 are concave arc surfaces, and the four corners of the top of the handle 2 are rounded. The staff's palm covers the handle 2, and the fingers press on the concave arc surfaces of the outer walls on both sides of the handle 2. It is ergonomic and more secure and comfortable to hold when grinding walls, profiles, and steel structures, effectively preventing the situation of falling off due to loss of grip, and can prevent fingers from being injured during grinding, with good use effect.
[0019] As an optional embodiment, the clamping seat 1 and the handle 2 are both made of plastic material. The plastic material is light in weight and does not add excessive weight compared to the traditional way of directly holding the sand block 5 by hand, making it more comfortable to use.
[0020] Principle of the utility model
[0021] When in use, the sand block 5 is pressed hard into the placement groove 3, so that the outer wall of the sand block 5 fits with the inner wall of the placement groove 3, and the inverted hook 4 can squeeze and limit the sand block 5, effectively preventing the sand block 5 from falling from the placement groove 3. When it is necessary to grind wall decoration, profiles, steel structures and other places, the staff covers the handle 2 with their palms and presses their fingers on the concave arc surfaces of the outer walls on both sides of the handle 2, which is ergonomic, more firm and comfortable to hold, effectively preventing the sand block 5 from falling, and can prevent injuries to fingers during grinding, with good use effect.
[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
