Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor with an easy-to-replace motor cover. Background Technology

[0002] In circuit diagrams, an electric motor is represented by the letter M. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines. A generator is represented by the letter G. Its main function is to convert mechanical energy into electrical energy. Electric motors can be classified according to the type of power source: DC motors and AC motors; according to structure and working principle: DC motors, asynchronous motors, and synchronous motors; according to starting and running methods: capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors; according to application: drive motors and control motors; according to rotor structure: squirrel-cage induction motors and wound-rotor induction motors; and according to operating speed: high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors. Low-speed motors are further divided into geared motors, electromagnetic geared motors, torque motors, and claw-pole synchronous motors, etc.

[0003] When using a motor, it needs to be inspected regularly. During inspection, the motor cover needs to be removed. Since the motor cover is usually connected to the motor with screws, and the screws are small, they are easy to fall off the motor cover. Finding the fallen screws can be difficult, which increases the difficulty of disassembling the motor. Utility Model Content

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Example

[0021] refer to Figures 1-4 A motor with an easily replaceable motor cover includes a motor body 1. A motor cover 2 is detachably mounted on one end of the motor body 1. The motor cover 2 includes a protective shell 201 with a hollow cylindrical structure. One end of the protective shell 201 has a first mounting plate 202 with an arc-shaped structure. Two symmetrically arranged end plates 203 are provided on the side of the first mounting plate 202 away from the protective shell 201. A first connecting rod 204 is provided on the outer wall of one end of the first mounting plate 202. A threaded rod 205 is provided at the bottom end of the first connecting rod 204. A second mounting plate 206, adapted to the first mounting plate 202, is hinged to the other end of the first mounting plate 202. The outer side wall of the second mounting plate 206 away from the first mounting plate 202 is provided with a second connecting rod 207 corresponding to the first connecting rod 204. A connecting joint 208 is slidably connected to the second connecting rod 207. The top end of the connecting joint 208 is provided with a threaded connecting groove 209 that is screwed to the threaded rod 205. By rotating the connecting joint 208, it is displaced and threadedly connected to the threaded rod 205, thereby limiting and fixing the second mounting plate 206, so that the motor cover 2 is fixedly installed on the motor body 1. Alternatively, the connecting joint 208 can be rotated to release the fixed connection with the threaded rod 205, thereby disassembling the motor cover 2.

[0022] Furthermore, both the first mounting plate 202 and the second mounting plate 206 have snap-fit ​​plates 210 on their inner sidewalls, and the outer sidewall of one end of the motor body 1 has a snap-fit ​​groove 101 that can be snapped into by the snap-fit ​​plate 210. The connection strength between the motor cover 2 and the motor body 1 is enhanced by the snap-fit ​​groove 101 and the snap-fit ​​plate 210.

[0023] Furthermore, the top of the outer side wall of the motor body 1 is provided with positioning rods 102 that correspond one-to-one with the end plate 203. The end plate 203 is provided with positioning holes 211 through which the positioning rods 102 can be inserted. Through the positioning holes 211 and the positioning rods 102, the installation of the motor cover 2 and the motor body 1 can be positioned, and the sliding displacement of the motor cover 2 can be prevented, thereby improving the stability of the installation of the motor cover 2.

[0024] Furthermore, the other end of the protective shell 201 is provided with a protective cover plate 212, and the protective cover plate 212 is provided with a plurality of ventilation holes 213.

[0025] Furthermore, the second connecting rod 207 is provided with a limiting plate 214 at its top end, and the connecting joint 208 is provided with a limiting groove 215 that allows the limiting plate 214 to move. By setting the limiting plate 214, the connecting joint 208 is always connected to the second connecting rod 207, thus preventing the connecting joint 208 from being lost.

[0026] The working principle of this utility model:

[0027] During installation, firstly, rotate and open the second mounting plate 206 of the motor cover 2. Then, align the positioning hole 211 of the motor cover 2 with the positioning rod 102 of the motor body 1 and insert it downwards from the top of the motor body 1. At the same time as insertion, the snap-fit ​​plate 210 in the first mounting plate 202 snaps into the snap-fit ​​groove 101 in the upper half of the motor body 1. Then, rotate the second mounting plate 206 to close it with the first mounting plate 202. At the same time as rotation, the snap-fit ​​plate 210 in the second mounting plate 206 snaps into the snap-fit ​​groove 101 in the lower half of the motor body 1. At this time, the connecting joint 208 on the second mounting plate 206 corresponds to the threaded rod 205 on the first mounting plate 202. Rotate the connecting joint 208 to displace and thread it into the threaded connection with the threaded rod 205, thereby limiting and fixing the second mounting plate 206, and thus fixing the motor cover 2 on the motor body 1.

[0028] During disassembly, rotate the connecting joint 208 to release it from the fixed connection with the threaded rod 205, then rotate the second mounting plate 206 to open it, and move the motor cover 2 upward to disassemble it.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
