[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] This utility model provides a motor with an easy-to-replace motor cover, mainly to solve the problem that the existing motor cover 2 is connected to the motor by multiple sets of bolts, which are prone to corrosion after long-term use, resulting in difficult and time-consuming disassembly. Its core innovation lies in the use of a special connection structure to achieve convenient replacement of the cover 2.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] A type of motor with an easily replaceable motor cover, such as Figure 1 - Figure 5 As shown, the motor mainly includes a body 1 and a housing 2;

[0035] The inner wall of the cover 2 is equipped with multiple sets of positioning blocks 3. The outer wall of the body 1 is provided with a long groove 4, a horizontal groove 5, and a positioning groove 6 for limiting the positioning blocks 3. A positioning plate 7 that is attached to the outer wall of the positioning block 3 is slidably installed in the horizontal groove 5. An elastic element 8 that is attached to the body 1 is installed on the outer wall of the positioning plate 7. The body 1 is also provided with a limiting mechanism corresponding to the positioning plate 7. The outer wall of the cover 2 is provided with a disassembly structure. This structural design makes the connection between the cover 2 and the body 1 more stable and easier to disassemble. Compared with the traditional motor housing connection method, it has obvious advantages and also provides convenience for subsequent disassembly and installation operations.

[0036] For example, multiple sets of positioning blocks 3 are installed at the same angle on the inner wall of the cover 2. The installation position of the positioning blocks 3 is not on the same plane as the outer wall of the cover 2 near the body 1, so that the cover 2 can cover the transverse groove 5 after being installed on the body 1. At the same time, the beveled design of the corners of the positioning blocks 3 and the opening corners of the long groove 4 can effectively reduce the difficulty of the positioning blocks 3 entering the long groove 4 and the positioning groove 6, as well as sliding in the transverse groove 5.

[0037] In this embodiment, the length of the long groove 4 is greater than the length of the positioning groove 6, so that the positioning groove 6 will not penetrate the outer wall of the body 1 like the long groove 4, ensuring that the positioning block 3 can be smoothly fixed after entering its interior. At the same time, the long groove 4 and the positioning groove 6 are connected by the transverse groove 5, and the overall cross section is L-shaped, ensuring that the positioning block 3 can move smoothly within the long groove 4, the positioning groove 6 and the transverse groove 5. Furthermore, the width of the long groove 4 and the positioning groove 6 corresponds to the width of the positioning block 3, further ensuring that the positioning block 3 can smoothly enter the positioning groove 6. Meanwhile, since the length of the positioning groove 6 is greater than half the thickness of the positioning block 3 and less than the overall thickness of the positioning block 3, it ensures that the positioning block 3 will be smoothly restricted and fixed after entering the positioning groove 6. This positioning structure can ensure that the cover 2 and the body 1 are accurately installed and have good stability after installation.

[0038] The limiting mechanism in this embodiment includes a limiting member 71 and a limiting groove 72;

[0039] The limiting component 71 is fixedly installed on the outer wall of the positioning plate 7, and a limiting groove 72 corresponding to the limiting component 71 is opened in the outer wall of the main body 1. The setting of the limiting mechanism can further fix the position of the positioning plate 7 and prevent it from moving accidentally during use, thereby ensuring the reliability of the connection between the cover 2 and the main body 1.

[0040] In some examples, the limiting member 71 is a set of rectangular plates fixedly connected to the positioning plate 7, which is slidably connected to the body 1 through the limiting groove 72 to limit and support the positioning plate 7.

[0041] Of course, in other examples, the limiting member 71 can be a cylindrical slide bar, and the limiting groove 72 can also be set to a shape corresponding to the cylindrical slide bar. In this embodiment, the limiting member 71 is not directly and completely limited.

[0042] This embodiment also includes a disassembly structure;

[0043] In some examples, the easy-to-disassemble structure includes a cross groove 21 formed on the outer wall of the housing 2. The design of the easy-to-disassemble structure allows the user to apply external force by inserting a tool into the cross groove 21 when disassembling the housing 2. Items that can be inserted into the cross groove 21, such as steel plates, can be used to complete the disassembly operation more conveniently and quickly.

[0044] Of course, in other examples, the easy-to-disassemble structure includes multiple sets of cross grooves 21 opened at angles on the outer wall of the housing 2.

[0045] The working principle of this utility model is as follows: when it is necessary to disassemble the cover 2 of the main body 1;

[0046] First, push the cover 2 towards the body 1, causing multiple sets of positioning blocks 3 to slide towards the positioning plate 7 simultaneously, causing the positioning blocks 3 to slide out of the positioning groove 6. At this time, rotate the cover 2, causing the positioning blocks 3 to slide against the outer wall of the positioning plate 7 in the transverse groove 5 until their outer wall is in contact with the side wall of the transverse groove 5. Then, pull the cover 2 outward. At this time, the positioning blocks 3 will separate from the body 1 through the long groove 4. At this time, the user can remove the cover 2, making the operation of removing the cover 2 very convenient.

[0047] At the same time, when the positioning plate 7 is squeezed by the positioning block 3, it will slide towards the elastic member 8, so that the elastic member 8 will be subjected to the squeezing force given by the positioning plate 7, causing the elastic member 8 to be in a compressed state. When the positioning plate 7 loses the pressure given by the positioning block 3, it will be pushed towards the positioning groove 6 under the action of the elastic member 8. If the positioning block 3 is not located in the positioning groove 6 at this time, the positioning plate 7 will be pushed to the outer wall of the transverse groove 5 near the outer side of the body 1 under the action of the elastic member 8.

[0048] Secondly, when it is necessary to install the cover 2 onto the main body 1, by pushing the cover 2, the positioning block 3 on its inner wall enters the long groove 4. Then, the cover 2 needs to be pushed urgently, which will cause the positioning block 3 to start pushing the positioning plate 7 until the distance between the positioning plate 7 and the inner wall of the transverse groove 5 is greater than the positioning block 3. Then the cover 2 can be rotated until it can no longer be rotated. At this time, the positioning block 3 will correspond to the position of the positioning groove 6. At this time, the user can release the cover 2. Then the positioning plate 7 will push the positioning block 3 into the positioning groove 6 under the action of the elastic element 8, and fix the positioning block 3, thus completing the installation of the cover 2.

[0049] Because the outer wall of the cover 2 does not have through holes corresponding to the bolts, the appearance of the cover 2 is effectively improved. After the cover 2 is installed on the main body 1, it will cover the horizontal groove 5, so that the long groove 4, the horizontal groove 5 and the positioning groove 6 will all be protected by the cover 2, effectively reducing the impact of the external environment on the components in the long groove 4, the horizontal groove 5 and the positioning groove 6.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
