[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] Please see Figures 1-4 This utility model provides a technical solution: a grinding wheel anti-detachment quick positioning and installation structure, the grinding wheel anti-detachment quick positioning and installation structure includes: a grinding wheel head protrusion 4, the grinding wheel head protrusion 4 is connected to the grinding wheel head body 3, the grinding wheel head body 3 is provided with a pull block 6, the pull block 6 is provided with a locking block 7, one end of the locking block 7 is locked in the connecting groove 8; a connecting head body 1, the connecting head body 1 is provided with a connecting head protrusion 2, the connecting head body 1 is provided with a locking groove 9 and a circular groove 17, and a connecting post 16 is locked in the circular groove 17;

[0025] In actual use, the connector protrusion 2 and the grinding wheel head protrusion 4 cooperate with each other. At this time, the position is just right so that the screw holes of the upper and lower parts are aligned. This prevents the grinding wheel head body 3 from falling down due to gravity and damaging the grinding wheel and other components if it is not found when dragging the grinding wheel head body 3 for a long time.

[0026] Example 2

[0027] Based on Embodiment 1, the connecting column 16 is cylindrical in shape and is fixedly connected to the grinding wheel head body 3. Several grinding wheel head protrusions 4 are fixedly connected to the grinding wheel head body 3. The operator inserts the connecting column 16 fixedly connected to the grinding wheel head body 3 into the circular groove 17 opened on the connecting head body 1. At this time, the locking block 7 is squeezed and slides along the connecting groove 8 until one end face of the locking block 7 is flush with the end face of the grinding wheel head body 3.

[0028] Several connector protrusions 2 are fixedly connected to the connector body 1. A circular groove 17 is formed on the connector body 1, the inner diameter of which is equal to the diameter of the connecting post 16 fixedly connected to the grinding wheel head body 3. The grinding wheel head body 3 is mounted on the connector body 1 using hexagonal socket head cap screws 10. When the operator rotates the grinding wheel head body 3, the several connector protrusions 2 fixedly connected to the connector body 1 and the several grinding wheel head protrusions 4 fixedly connected to the grinding wheel head body 3 engage with each other, forming the shape shown in the example. Figure 1 When in the state, temporary locking is completed. At this time, the position is just positioned so that the screw holes of the upper and lower parts are aligned. This prevents the grinding wheel head body 3 from falling down due to gravity and damaging the grinding wheel and other components because it cannot find the screw positioning hole after a long time of dragging.

[0029] A locking block 7 is fixedly connected to the pull block 6. The locking block 7 has a square plate-shaped structure. The locking block 7 can slide along the connecting groove 8 opened on the grinding wheel head body 3 and be locked into the locking groove 9 opened on the connecting head body 1. The locking groove 9 has a square groove-shaped structure, and at this time the connecting groove 8 and the locking groove 9 correspond exactly.

[0030] The pull block 6 has an "I" shaped plate structure. One end of the pull block 6 is stuck in the groove 5 opened on the grinding wheel head body 3 and can slide along the groove 5. The groove 5 has a "convex" groove structure. The thrust spring 13 pushes the limit plate 14 and the pull block 6 to slide along the groove 5, so that the locking block 7 is locked into the locking groove 9 along the connecting groove 8, and a temporary lock is completed. The above can realize the rotational locking between the connecting head body 1 and the grinding wheel head body 3, and prevent the connecting head protrusion 2 from separating from the grinding wheel head protrusion 4 when the grinding wheel head body 3 is rotated, which would cause the grinding wheel head body 3 to fall off and damage the grinding wheel and other components. It is convenient for personnel to use. Finally, it is installed with the internal hex bolt 10.

[0031] Example 3

[0032] Based on Embodiment 2, a thrust spring 13 is provided for ease of use by personnel in the later stage. The other end of the thrust spring 13 is fixedly connected to the mounting block 11. One end of the mounting block 11 is stuck in the slide groove 5. The mounting block 11 is installed on the grinding wheel head body 3 by fixing bolts 12. The mounting block 11 is a combination of a "convex" plate and an arc plate. When the elasticity of the thrust spring 13 weakens, it needs to be replaced. The operator can unscrew and remove the fixing bolts 12 on the mounting block 11 and pull the mounting block 11 so that one end of it is disengaged from the slide groove 5. During the process, the thrust spring 13 is also stretched.

[0033] A limiting groove 15 is provided on the pull block 6. The limiting groove 15 has a "convex" groove structure. A limiting plate 14 is inserted in the limiting groove 15. The limiting plate 14 has a "convex" plate structure. The limiting plate 14 is fixedly connected to one end of the thrust spring 13. The limiting plate 14 can be slid out along the limiting groove 15. The limiting plate 14, the thrust spring 13 and the mounting block 11 can be disassembled. Personnel can then replace the new assembly consisting of the limiting plate 14, the thrust spring 13 and the mounting block 11, which is convenient for personnel to use and improves the effectiveness of the device.

[0034] In actual use, the grinding wheel head body 3 is rotated to a certain position and then locked. This causes the connecting head protrusions 2 fixedly connected to the connecting head body 1 and the grinding wheel head protrusions 4 fixedly connected to the grinding wheel head body 3 to cooperate with each other. At this time, the position is just right so that the screw holes of the upper and lower parts are aligned, which facilitates subsequent installation. This method can also temporarily fix the grinding wheel head body 3 to the connecting head body 1. Furthermore, by inserting one end of the locking block 7 into the locking groove 9, it can prevent the connecting head protrusions 2 and the grinding wheel head protrusions 4 from disengaging due to rotation between the connecting head body 1 and the grinding wheel head body 3, thus completing the locking. The above-described structures cooperate with each other, which facilitates the installation work and can effectively prevent the grinding wheel head body 3 from falling and damaging the grinding wheel head body 3 and other components due to the inability to find the screw positioning holes after a long time.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
