Technical Field
[0001] The utility model relates to the technical field of diamond wiping blocks, in particular to a wear-resistant diamond hand wiping block. Background Art
[0002] Diamond is the raw stone of diamond, which is a natural element mineral composed of carbon. Diamond is a relatively hard substance in nature. Some industries use diamond to make polishing blocks for grinding other substances with lower hardness.
[0003] Existing diamond grinding blocks are generally composed of a hand-held outer shell and an internal diamond friction block. Due to the different objects to be polished, the mesh sizes of the required diamond grinding blocks are also different. Existing diamond grinding blocks often only have one mesh size. Therefore, users need to always have multiple grinding blocks of different mesh sizes, which need to be searched in advance when using, which is inconvenient. Utility Model Content
[0004] The utility model aims to provide a wear-resistant diamond hand-wiping block to solve the problems raised in the above-mentioned background technology.

[0010] Preferably, the positions of the four limiting holes match those of the four friction surfaces.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. When the wear-resistant diamond hand wiper is not in use, the spring telescopic rod will drive the protective ring, the rotating shaft and the wiper structure to retract into the inside of the installation slot to reduce the influence of the external environment on the wiper structure. When in use, the protective ring is pushed downward by external force, thereby driving the protective ring, the rotating shaft and the wiper structure to move downward. When the protective ring moves to the lowest end of the side slot, the wiper structure is at the lowest point and part of the area is exposed outside the installation slot. Then, the rotating wheel is manually rotated to drive the rotating shaft to rotate, and the rotating shaft drives the wiper structure to rotate, so that the mesh number required by the user can be selected as needed.

At this time, the position of the limit hole will coincide with the position of the through hole. At this time, the limit structure is inserted into the limit hole to limit the wiper structure from continuing to move. After use, the limit structure is pulled out and the wiper structure will be reset under the action of the spring telescopic rod. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 5As shown, the wear-resistant diamond hand-wiping block of this embodiment includes a shell 1, a mounting groove 4 is provided at the bottom end of the shell 1, a side groove 2 penetrating the shell 1 is provided on the right end surface of the shell 1, and the upper and lower ends of the side groove 2 are both semicircular, and a plurality of wiper structures 5 with different mesh numbers are rotatably connected inside the mounting groove 4, and the wiper structure 5 includes four surfaces with different mesh numbers for grinding materials of different materials, and the left end of the wiper structure 5 is slidably connected to the inner wall of the mounting groove 4 through a connecting shaft, and the connecting shaft can be lifted and lowered on the inner wall surface of the mounting groove 4, and a rotating shaft 8 is installed at the right end of the wiper structure 5, and the rotating shaft 8 extends to the outside through the side groove 2 and is installed with a rotating wheel 3, and the rotating shaft 8 and the wiper can be driven by rotating the rotating wheel 3 The structure 5 rotates synchronously, and a protective ring 7 is provided on the surface of the rotating shaft 8. The rotating shaft 8 can rotate inside the protective ring 7, and the protective ring 7 cannot rotate. The protective ring 7 is slidably connected to the inside of the side groove 2 and can slide up and down inside the side groove 2. A spring telescopic rod 6 is installed on the upper end of the protective ring 7, and the upper end of the spring telescopic rod 6 is in contact with the inside of the mounting groove 4. Under normal conditions, under the action of the spring telescopic rod 6, the protective ring 7 is at the uppermost end of the side groove 2. At this time, the rotating shaft 8 inside the protective ring 7 and the wiper structure 5 are all inside the mounting groove 4. When the protective ring 7 moves to the lowermost end of the side groove 2 under the action of external force, the lowest end of the wiper structure 5 is located outside the mounting groove 4.
[0024] Specifically, the wiper structure 5 includes a friction surface 501, a dividing groove 502, a limiting hole 503 and a wiper body 504. The surface array of the wiper body 504 is equipped with four friction surfaces 501 of the same size, each friction surface 501 is separated by the dividing groove 502, and the left end of the wiper body 504 is provided with four limiting holes 503 of the same size. The mesh numbers of the four friction surfaces 501 are different. The friction surfaces 501 of different mesh numbers are distinguished by the dividing groove 502. The four limiting holes 503 are as follows: Figure 4 Array distribution is shown.
[0025] Furthermore, the left end of the housing 1 is provided with two through holes 10 located on the same vertical line, and a limiting structure 9 is slidably installed inside the through hole 10 , and the position of the wiper structure 5 can be limited by the limiting structure 9 .
[0026] Furthermore, the limiting structure 9 includes a pull plate 901, a connecting rod 902 and a limiting cylinder 903. An adaptable connecting rod 902 is slidably connected inside the through hole 10. The left ends of the two connecting rods 902 are jointly installed with a pull plate 901, and the right ends of the two connecting rods 902 are each installed with a limiting cylinder 903 located inside the mounting groove 4. The size of the limiting cylinder 903 is larger than the size of the through hole 10, and the limiting cylinder 903 is adapted to the limiting hole 503. When the wiper structure 5 needs to be used, the position of the wiper structure 5 is lowered to the lowest point. At this time, the position of the limiting hole 503 will coincide with the position of the through hole 10. At this time, the limiting cylinder 903 is inserted into the limiting hole 503 to limit the wiper structure 5 from continuing to move. After use, the limiting cylinder 903 is pulled out, and the wiper structure 5 will be reset under the action of the spring telescopic rod 6. Since the size of the limiting cylinder 903 is larger than the size of the through hole 10, the limiting structure 9 cannot be separated from the through hole 10.
[0027] Furthermore, an arc-shaped groove 11 is provided at both the front and rear ends of the shell 1 , and the arc-shaped groove 11 on both sides can facilitate the user to take the shell 1 .
[0028] Furthermore, the four limiting holes 503 match the positions of the four friction surfaces 501. When the friction surface 501 is selected, the four limiting holes 503 correspond to four different friction surfaces 501 respectively. When a limiting hole 503 is located at the lowest end, the corresponding friction surface 501 is also located at the lowest end.
[0029] The method of using this embodiment is as follows: when not in use, under the action of the spring telescopic rod 6, the protective ring 7, the rotating shaft 8 and the wiping block structure 5 will be driven to retract into the interior of the installation groove 4, reducing the influence of the external environment on the wiping block structure 5. When in use, the protective ring 7 is pushed downward by external force, thereby driving the protective ring 7, the rotating shaft 8 and the wiping block structure 5 to move downward. When the protective ring 7 moves to the lowest end of the side groove 2, the wiping block structure 5 is at the lowest point, and a part of the area will be exposed to the outside of the installation groove 4. Then, by manually rotating the rotating wheel 3, the rotating wheel 3 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the wiping block structure 5 to rotate, so that the mesh number required by the user can be selected as needed.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
