Description

Technical Field

[0001] This utility model relates to the field of permanent magnet motor technology, specifically to a high-efficiency permanent magnet precision motor exhaust shroud component with a quick positioning and disassembly structure. Background Technology

[0002] High-efficiency permanent magnet precision motors refer to motors that use permanent magnet materials as the magnetic field source and achieve high efficiency, high reliability, and precise control through optimized design and manufacturing processes. Based on their operating methods, high-efficiency permanent magnet precision motors can be divided into two main categories: permanent magnet DC motors and permanent magnet synchronous motors.

[0003] An exhaust hood is an important component of a ventilation system, typically connected to a fan or other ventilation equipment, used to exhaust air from inside the equipment to the external environment. Its main function is to ensure the smooth operation of the ventilation system while preventing external debris or rainwater from entering the system.

[0004] The existing permanent magnet precision motor has an exhaust shroud on the outward end, and the exhaust shroud has a hole in the middle to facilitate heat dissipation. However, the hole in the middle of the exhaust shroud needs to be disassembled and replaced, which requires cutting and replacing the entire device, making the replacement of the exhaust shroud quite troublesome and requiring a lot of time for maintenance. Utility Model Content

The nut and the threaded rod can thread-fix the connecting housing and the shielding frame, making it convenient to disassemble and replace the shielding frame.

[0010] Preferably, the limiting plug is inserted into the right end of the outer shell, and there are four limiting plugs. The four limiting plugs are distributed on the left end of the connecting outer shell. The limiting plugs are inserted into the connection between the connecting outer shell and the outer shell, so that the limiting plugs and the outer shell can be connected and fixed.

[0011] Preferably, the limiting plug is movably connected to the surface of the threaded rod. The surface of the threaded rod rotates the nut, which can thread-fix the limiting plug and the threaded rod, thereby limiting the position of the limiting plug.

[0012] Preferably, the connecting shell is movably connected to the right end of the outer shell, and the connecting shell and the outer shell are movably connected.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 The present invention provides the following technical solution:

[0026] The high-efficiency permanent magnet precision motor exhaust shroud component with a quick positioning and disassembly structure includes a metal housing 1 and a stator 2. A rotor 3 is installed inside the metal housing 1, and a fan blade 4 is threaded to the right end of the rotor 3. The stator 2 is fixedly connected to the inside of the metal housing 1.

[0027] The metal casing 1 includes a cover plate 11, a casing 12, an air outlet hood 13, and a metal frame 14. The cover plate 11 is threaded to the left side surface of the casing 12, and the air outlet hood 13 is threaded to the right end of the casing 12. The stator 2 is installed on the inner wall surface of the casing 12, the cover plate 11 is installed on the left end of the rotor 3, and the rotor 3 is installed on the inner wall surface of the metal frame 14. The cover plate 11 and the casing 12 are installed together, which can limit the stator 2 and the rotor 3 inside the casing 12 and protect the safety of the stator 2 and the rotor 3. The metal frame 14 is fixedly connected to the right end inside the casing 12.

[0028] The air outlet cover 13 includes a connecting shell 131, a shielding frame 132, a metal insert 133, a connector 134, a threaded rod 135, and a limiting insert 136. The shielding frame 132 is inserted into the right end of the connecting shell 131, which is movably connected to the right end of the shell 12. The connecting shell 131 and the shell 12 are movably connected. The limiting insert 136 is inserted into the connection between the shell 12 and the connecting shell 131, thus limiting and fixing the position of the limiting insert 136 and the shell 12. The threaded rod 135 is fixedly connected to the left end of the connecting shell 131, and the limiting insert 136 is movably connected to the surface of the threaded rod 135. Rotating the nut on the surface of the threaded rod 135 can thread the limiting insert 136 and the threaded rod 135 together, thereby limiting the position of the limiting insert 136. In the positioning operation, the threaded rod 135 is inserted into the right end of the connecting housing 131. A nut is rotatably connected to the surface of the threaded rod 135. The nut and the threaded rod 135 can thread-fix the connecting housing 131 and the shielding frame 132, making it convenient to disassemble and replace the shielding frame 132. The connector 134 is fixedly connected to the inner wall surface of the metal plug 133. The limiting plug 136 is inserted into the left end of the connecting housing 131 and the right end of the housing 12. There are four limiting plugs 136, which are distributed on the left end of the connecting housing 131. The limiting plugs 136 are inserted into the connection between the connecting housing 131 and the housing 12, thereby fixing the limiting plug 136 and the housing 12. The metal plug 133 is movably connected to the right side surface of the inner wall of the connecting housing 131.

[0029] When in use, push the shielding frame 132 from right to left to insert the shielding frame 132 into the interior of the connecting housing 131, initially connecting the shielding frame 132 and the connecting housing 131. The shielding frame 132 can be quickly and easily disassembled and replaced, thereby increasing the service life of the device.

[0030] The metal insert 133 is pushed into the interior of the connecting housing 131. The metal insert 133 can push the connector 134 into the connection between the connecting housing 131 and the shielding frame 132. Then, the nut is turned, and the nut can fix the shielding frame 132 and the connecting housing 131 with threads, thereby determining the position of the shielding frame 132.

[0031] Push the connecting housing 131 from right to left to connect the connecting housing 131 and the housing 12, thereby determining the position of the connecting housing 131 and facilitating its disassembly and replacement.

[0032] Pushing the limiting plug 136 downwards causes the limiting plug 136 to be inserted into the connection between the outer shell 12 and the connecting shell 131, thereby initially limiting and fixing the connection shell 131 and the outer shell 12, preventing the connecting shell 131 from detaching from the outer shell 12, and protecting the safety of the outer shell 12 and the connecting shell 131.

[0033] When the limiting plug 136 moves downward, it slides on the surface of the threaded rod 135. Then, the nut is rotated, and the nut rotates on the surface of the threaded rod 135. The bottom surface of the nut connects with the top surface of the limiting plug 136, thereby limiting and fixing the position of the limiting plug 136, and thus determining the position of the connecting housing 131.

[0034] 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 the 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.
