DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] In combination with the drawings Figures 1-4 In the embodiment, an engine impeller convenient to disassemble comprises a fixed shaft 1, a movable slot 11 is fixedly installed inside the fixed shaft 1, four limiting rings 12 are fixedly installed around the inside of the movable slot 11, the limiting rings 12 are annular in shape, a center block 13 is fixedly installed in the middle of the inside of the movable slot 11, a connecting block 14 is fixedly installed on one side of the fixed shaft 1, and a main shaft 15 is fixedly installed on one side of the connecting block 14.

[0025] Specifically, the fixed shaft 1 and the main shaft 15 are connected by the connecting block 14, the center is fixed by the center block 13 inside the movable groove 11, and the mounting plate 22 is limited and supported by the limiting ring 12.

[0026] Four support plates 2 are movably connected around the inside of the movable groove 11. A support spring 21 is fixedly installed on one side of the support plate 2. An installation plate 22 is fixedly installed on one side of the support spring 21. An insertion rod 23 is fixedly installed in the middle of one side of the installation plate 22. A limit plate 24 is fixedly installed on one side of the insertion rod 23. An insertion post 25 is movably connected to the outside of the limit plate 24. A retaining ring 26 is fixedly installed on one side of the inside of the insertion post 25. The retaining ring 26 is annular in shape. A metal head 27 is fixedly installed on one side of the insertion post 25. The metal head 27 is semi-circular in shape.

[0027] Specifically, the support spring 21 between the mounting plate 22 and the support plate 2 can achieve the effect of retraction support. The insertion post 25 moves outside the insertion rod 23 and is limited by the limiting plate 24 and the retaining ring 26, thereby preventing the insertion post 25 from falling off.

[0028] An impeller body 3 is movably connected to the outside of the fixed shaft 1. A fixed groove 31 is fixedly installed in the middle of the impeller body 3. Four connecting grooves 32 are fixedly installed inside the impeller body 3. A retaining ring 33 is fixedly installed on one side of the inside of the connecting groove 32. The retaining ring 33 is in the shape of an annular ring. A magnetic suction plate 34 is movably connected inside the connecting groove 32. The magnetic suction plate 34 is in the shape of a circle. A connecting column 35 is fixedly installed on one side of the magnetic suction plate 34.

[0029] Specifically, the fixed groove 31 can be connected to the fixed shaft 1, the retaining ring 33 can limit the magnetic plate 34, thereby preventing the connecting post 35 from falling off, and the magnetic plate 34 can attract the retaining ring 33 and the metal head 27 for fixation.

[0030] Working principle: First, the impeller body 3 is fitted and connected to the fixed shaft 1 through its internal fixed groove 31. The semi-circular shape of the metal head 27 allows it to insert into the movable groove 11 when the impeller body 3 is pushed, causing the support spring 21 between the mounting plate 22 and the support plate 2 to contract. This allows the impeller body 3 to be inserted. The rebound of the support spring 21 allows the metal head 27 to be inserted into the connecting grooves 32 around the fixed groove 31, thus fixing the impeller body 3 and improving the ease of installation of this easily disassembled engine impeller. The centrifugal force of the rotating impeller body 3 causes the insertion post 25 to move outwards. The limiting plate 24 on one side of the insertion rod 23 and the insertion post 25... The internal retaining ring 26 limits the insertion post 25, preventing it from detaching from the insertion rod 23. Simultaneously, the mounting plate 22 moves within the movable groove 11, and is further limited by the limiting ring 12, allowing the insertion post 25 to be inserted into the connecting groove 32. Centrifugal force causes the metal head 27 to be attracted by the magnetic plate 34, which in turn attracts the retaining ring 33, improving stability and preventing the easily detachable engine impeller from falling off during use. When disassembly is required, pressing the four connecting posts 35 causes the metal head 27 to retract into the movable groove 11, retracting the support spring 21, allowing the impeller body 3 to be removed. This enhances the convenience and practicality of the easily detachable engine impeller.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
