Description

Technical Field

[0001] This utility model relates to the field of three-phase asynchronous motor technology, specifically a three-phase asynchronous motor that can be quickly assembled. Background Technology

[0002] Three-phase asynchronous motors are widely used power equipment in industrial fields. Structurally, they mainly consist of two parts: the stator and the rotor. The stator has three-phase windings, which generate a rotating magnetic field when three-phase alternating current is applied. The rotor is usually of two types: squirrel-cage and wound-rotor. The squirrel-cage rotor is simple in structure and robust and durable; the wound-rotor can improve starting and speed regulation performance by connecting external resistors. In terms of working principle, the rotating magnetic field cuts the rotor conductors, generating an induced electromotive force and current in the rotor. The current-carrying conductors are subjected to electromagnetic force in the magnetic field, thus forming an electromagnetic torque, causing the rotor to rotate following the rotating magnetic field. However, the rotor speed is always slightly lower than the speed of the rotating magnetic field, which is why it is called "asynchronous." Three-phase asynchronous motors have advantages such as simple structure, reliable operation, low cost, and convenient maintenance, and are widely used in various industrial production machinery, such as machine tools, fans, and water pumps, providing powerful power support for modern production. According to the utility model disclosed in patent authorization announcement number CN221151116U, a three-phase asynchronous motor that can be quickly assembled includes an asynchronous motor body, a rotating shaft rotatably connected to the middle of the asynchronous motor body, and a motor fan cover that is engaged and installed at the right end of the asynchronous motor body. A mounting ring is provided, with a fan blade fixedly connected to the outside of the mounting ring. The mounting ring is sleeved on the outside of the rotating shaft, and a slotted connection is made between the mounting ring and a protrusion. The mounting ring drives the fan blade to rotate at the right end of the asynchronous motor body through the protrusion and the rotating shaft. A limiting mechanism is provided, which is set at an equal angle on the outside of the motor fan cover.

[0003] Currently, there are three-phase asynchronous motors that can be quickly assembled. However, in actual installation, there are inconveniences when assembling them with the support base, making the assembly process less convenient. This motor was originally marketed for its quick assembly advantage, but problems have arisen in the installation process with the support base. Workers may encounter difficulties such as component alignment problems and cumbersome installation steps when connecting the two, making the entire assembly work inefficient and hindering the overall installation progress and efficiency, thus creating obstacles for installation in actual use scenarios. Utility Model Content

[0004] The purpose of this invention is to provide a three-phase asynchronous motor that can be quickly assembled, which solves the problem that it is inconvenient to assemble a three-phase asynchronous motor with a support base during installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-phase asynchronous motor that can be quickly assembled, comprising a base, a bracket fixedly connected to the upper end of the base, an organism fixedly connected to the upper end of the bracket, a support base contacting the lower end of the base, a slider slidably connected inside the base, a connecting block fixedly connected to the lower end of the slider, the connecting block slidably connected to the base, a locking block fixedly connected to the lower end of the connecting block, a locking groove provided inside the support base, a threaded rod rotatably connected inside the base, a knob fixedly connected to the end of the threaded rod away from the base, the knob contacting the base, and a limit mechanism provided on the base.

[0006] Preferably, the card block contacts the base and is slidably connected to the card slot. The design of the card block can limit the position of the base.

[0007] Preferably, the outer side of the threaded rod is provided with positive and negative threads, and the threaded rod is connected to the slider by threads. Through the design of the threaded rod, two sliders can be moved simultaneously.

[0008] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the base. The retaining ring is designed to limit the movement of the threaded rod.

[0009] Preferably, the limiting mechanism includes a limiting plate, which is slidably connected inside the base. A limiting block is fixedly connected to the side of the limiting plate near the knob. A guide rod is fixedly connected to the side of the limiting plate away from the limiting block. A guide plate is fixedly connected to the end of the guide rod away from the limiting plate. The guide plate is slidably connected to the base. A guide frame is fixedly connected inside the base. The guide frame is slidably connected to the guide rod and the guide plate. A spring is provided on the outer side of the guide frame. Through the design of the limiting mechanism, the knob can be limited, thereby keeping the machine body stable after installation.

[0010] Preferably, the limiting block is slidably connected to the base and to the knob. The design of the limiting block can limit the movement of the knob.

[0011] Preferably, one end of the spring contacts the guide plate, and the other end of the spring contacts the base. Through the design of the spring, the limiting block can be driven to limit the knob.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model innovatively incorporates components such as a slider, a locking block, and a threaded rod. During use, rotating the threaded rod causes a threaded motion between the rod and the slider, which in turn drives the locking block to engage with the support base, easily assembling the base and support. This ingenious component arrangement simplifies the assembly process, effectively solving the problem of inconvenient assembly of a quickly assembled three-phase asynchronous motor with the support base, thus improving installation efficiency and convenience.

[0013] 2. This utility model innovatively incorporates components such as a limiting plate, a limiting block, and a spring. The spring force drives the limiting plate to move, which in turn causes the limiting block to slide into the knob. This design effectively limits the knob's position, greatly enhancing its stability. Once the knob is precisely fixed, the machine body can maintain a stable working state after installation, effectively avoiding various problems caused by a loose knob. Attached Figure Description

Through the design of the locking block 32, the base 1 can be limited.

[0018] Please see Figure 2-4 The base 1 is internally connected to a threaded rod 34, which has positive and negative threads on its outer side. The threaded rod 34 is connected to the slider 3 by threads. The threaded rod 34 can drive two sliders 3 to move simultaneously. A retaining ring 35 is fixedly connected to the outer side of the threaded rod 34. The retaining ring 35 contacts the inner wall of the base 1. The retaining ring 35 can limit the movement of the threaded rod 34. A knob 36 is fixedly connected to the end of the threaded rod 34 away from the base 1. The knob 36 contacts the base 1. A limit mechanism 4 is provided on the base 1.

[0019] Please see Figure 2-4 The limiting mechanism 4 includes a limiting plate 41, which is slidably connected inside the base 1. A limiting block 42 is fixedly connected to the side of the limiting plate 41 near the knob 36. The limiting block 42 is slidably connected to the base 1 and to the knob 36. The limiting block 42 is designed to limit the knob 36. A guide rod 43 is fixedly connected to the side of the limiting plate 41 away from the limiting block 42. A guide plate 44 is fixedly connected to the end of the guide rod 43 away from the limiting plate 41. The guide plate 44 is connected to the base 1.

[0020] The specific implementation process of this utility model is as follows: When in use, move the limiting plate 41 away from the knob 36, so that the limiting plate 41 drives the guide rod 43 to move, so that the guide rod 43 drives the guide plate 44 to slide on the guide frame 45, so that the guide plate 44 squeezes the spring 46, and the limiting plate 41 drives the limiting block 42 to slide out of the knob 36, so that the limiting of the knob 36 can be released. By causing the base 1 to slide the locking block 32 into the slot 33 on the support base 2, and then rotating the knob 36, the knob 36 drives the threaded rod 34 to rotate, causing the threaded rod 34 and the slider 3 to move in a threaded motion, thereby causing the slider 3 to move on the threaded rod 34, causing the slider 3 to drive the connecting block 31 to move, causing the connecting block 31 to drive the locking block 32 to move, so that the locking block 32 is engaged with the support base 2, thus facilitating the quick assembly of the machine body 12 and the support base 2.
