Description

Technical Field

[0001] This utility model relates to the field of motor impeller technology, specifically a motor impeller with an assembled connection structure. Background Technology

[0002] A fan is formed by connecting a fan wheel to the shaft of a motor. In use, the fan wheel rotates along with the motor's output shaft to blow air onto an object, achieving heat dissipation or ventilation. The fan wheel is typically mounted on the motor shaft using an interference fit; the center of the fan wheel is interference-fitted onto the outside of the motor shaft, and a metal clamp is installed outside the center of the fan wheel to strengthen the connection between the fan wheel and the motor shaft. However, existing motor-driven fan wheels still have some problems in use:

[0003] For example, the technical solution of the motor impeller and fan with application number CN202321367527.9 is as follows: the motor impeller includes an impeller body and a connecting ring for sleeved on the outside of the motor shaft. The inner wall of the connecting ring has a keyway for accommodating a connecting key connected to the motor shaft. The impeller body has a central hole. The connecting ring is located in the central hole and connected to the impeller body. The connecting ring is a metal structural component. However, the existing motor impeller structure is relatively complex, the assembly process is still relatively complex, and the assembly stability is not ideal.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing motor-driven impeller. Utility Model Content

[0006] The purpose of this utility model is to provide a motor impeller with an assembled connection structure to solve the problems mentioned in the background art, such as the complicated internal structure of the impeller leading to troublesome assembly and insufficient connection stability.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A motor impeller with an assembled connection structure includes an impeller housing, which is annular in shape. A rotating shell is located inside the impeller housing. A rotating block is located at the bottom of the rotating shell, and a connecting shaft is connected to the bottom of the rotating block. The connecting shaft is connected to the motor output shaft. Several impeller blades are fixedly installed on the outside of the rotating shell, and the impeller blades are located inside the impeller housing. An annular ring is located inside the rotating shell, and full gears are provided on both the left and right sides of the annular ring. Threaded rods are connected to the bottom of each full gear, and the threaded rods are threadedly connected to the rotating block, which is located below the rotating shell.

[0009] Preferably, the annular ring is rotatably connected to the outer bottom surface of the rotating shell, and a half-tooth ring is provided on the inner side of the annular ring. A base plate is provided at the bottom of the annular ring, and a half-gear is fixedly installed on the top of the base plate.

[0010] Using the above technical solution, the rotation of the annular ring can drive the half gear to rotate synchronously, providing mechanical power for the forward and reverse movement of the threaded rod.

[0011] Preferably, a rotating rod is fixedly installed on the upper surface of the half gear, and a rotating handle is fixedly installed above the rotating rod.

[0012] Using the above technical solution, when the handle is rotated, the connected rotating rod drives the half gear and the ring to rotate synchronously.

[0013] Preferably, both sides of the half gear are meshed with full gears, and the full gears are rotatably connected to the bottom surface of the annular ring.

[0014] Using the above technical solution, when the half gear contacts the full gear, it drives the full gear to rotate in one direction. When the half gear of the ring contactes the full gear, it drives the full gear to rotate in the opposite direction, thereby causing the full gear to rotate intermittently in both directions.

[0015] Preferably, each of the gears has a threaded rod fixedly installed at its bottom, and the threaded rod passes through the annular ring and the bottom surface of the rotating shell, and the surface of the threaded rod has threads in multiple directions.

[0016] Using the above technical solution, the gear rotates intermittently in both directions, simultaneously driving the threaded rod to rotate in both directions, providing mechanical power for the connection with the rotating block.

[0017] Preferably, threaded holes are provided on both the left and right sides of the upper surface of the rotating block, and the threaded holes are provided with threads in multiple directions, and the threaded rod is threadedly connected to the threaded hole.

[0018] Using the above technical solution, the threaded rod can be threaded into the threaded hole when it rotates in both directions, realizing the quick installation of the rotating shell and the rotating block, while improving the stability of the connection.

[0019] Preferably, a threaded groove is provided on the upper edge of the interior of the rotating shell, and a threaded post is threadedly connected inside the threaded groove. The threaded post is fixedly installed at the bottom of the top cover, and the top cover is connected and installed on the top of the rotating shell.

[0020] Using the above technical solution, after the rotating shell and rotating block are installed, the top cover is rotated so that the bottom threaded post connects with the top of the threaded post, thus ensuring the integrity of the appearance while protecting the internal rotating structure.

When the rotating handle is rotated, the half gear and the annular ring are driven to rotate synchronously through the connected rotating rod. When the half gear contacts the full gear, it drives it to rotate in one direction. When the half-tooth ring of the annular ring contacts the full gear, it drives it to rotate in the opposite direction, thereby driving the full gear to rotate intermittently in the forward and reverse directions. The threaded rod can be threadedly connected to the threaded hole in the forward and reverse directions, which improves the assembly efficiency.

[0030] 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.

[0031] Please see Figure 1-5This utility model provides a technical solution:

[0032] A motor impeller with an assembled connection structure includes an impeller housing 1, which is annular. A rotating shell 3 is disposed inside the impeller housing 1. A rotating block 5 is disposed at the bottom of the rotating shell 3. A connecting shaft 2 is connected to the bottom of the rotating block 5 and is connected to the motor output shaft. Several impeller blades 4 are fixedly installed on the outside of the rotating shell 3 and are located inside the impeller housing 1. An annular ring 10 is disposed inside the rotating shell 3. Full gears 15 are disposed on both the left and right sides inside the annular ring 10. Threaded rods 16 are connected to the bottom of each full gear 15 and are threadedly connected to the rotating block 5. The rotating block 5 is located below the rotating shell 3.

[0033] An annular ring 10 is rotatably connected to the outer bottom surface of the rotating shell 3, and a half-tooth ring 11 is provided on the inner side of the annular ring 10. A base plate is provided at the bottom of the annular ring 10, and a half-gear 12 is fixedly installed on the top of the base plate. A rotating rod 13 is fixedly installed on the upper surface of the half-gear 12, and a rotating handle 14 is fixedly installed on the top of the rotating rod 13. Full gears 15 are meshed on both sides of the half-gear 12, and the full gears 15 are rotatably connected to the bottom surface of the annular ring 10. The rotation of the annular ring 10 can drive the half-gear 12 to rotate synchronously, providing mechanical power for the forward and reverse movement of the threaded rod 16. When the rotating handle 14 is rotated, the half-gear 12 and the annular ring 10 are driven to rotate synchronously through the connected rotating rod 13. When the half-gear 12 contacts the full gear 15, it drives it to rotate in one direction. When the half-tooth ring 11 of the annular ring 10 contacts the full gear 15, it drives it to rotate in the opposite direction, thereby driving the full gear 15 to rotate intermittently in both forward and reverse directions.

[0034] Each gear 15 has a threaded rod 16 fixedly mounted at its bottom, passing through the bottom surface of the annular ring 10 and the rotating housing 3. The threaded rod 16 has threads in multiple directions on its surface. The upper surface of the rotating block 5 has threaded holes 6 on both sides, with threads in multiple directions inside each hole. The threaded rod 16 is threadedly connected to the threaded hole 6. The gear 15 rotates intermittently in both directions, simultaneously driving the threaded rod 16 to rotate in both directions, providing mechanical power for its connection to the rotating block 5. When the threaded rod 16 rotates in both directions, it can be threaded into the threaded hole 6, enabling rapid installation of the rotating housing 3 and the rotating block 5, while simultaneously improving the stability of the connection.

[0035] A threaded groove 9 is provided on the upper edge of the interior of the rotating shell 3, and a threaded post 8 is threadedly connected inside the threaded groove 9. The threaded post 8 is fixedly installed at the bottom of the top cover 7, and the top cover 7 is connected and installed on top of the rotating shell 3. After the rotating shell 3 and the rotating block 5 are installed, the top cover 7 is rotated so that the threaded post 8 at its bottom connects with the threaded post 8 above it, thus ensuring the integrity of the appearance while protecting the internal rotating structure.

[0036] Working principle:

[0037] In use, rotating the handle 14 causes the connected rotating rod 13 to drive the half gear 12 and the ring 10 to rotate synchronously. When the half gear 12 contacts the full gear 15, it drives the full gear 15 to rotate in one direction. When the half gear ring 11 of the ring 10 contacts the full gear 15, it drives the full gear 15 to rotate in the opposite direction, thereby causing the full gear 15 to rotate intermittently in both directions. At the same time, it drives the threaded rod 16 to rotate in both directions, providing mechanical power for the connection with the rotating block 5. When the threaded rod 16 rotates in both directions, it can be threaded into the threaded hole 6, realizing the quick installation of the rotating shell 3 and the rotating block 5. After the rotating shell 3 and the rotating block 5 are installed, rotating the top cover 7 connects the bottom threaded post 8 with the top of the threaded post 8.
