[0022] 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.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] The inverter body 1, guide frame 2, reinforcing block 3, baffle 4, mounting back plate 5, limit stop frame 6, pull rod 7, positioning groove 8, insertion hole 9, pressing protrusion 10, through groove 11, elastic plate 12, receiving groove 13, locking block 14, protrusion 15, and fixing frame 16 of this application are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0025] Example 1:

[0026] Please see Figures 1-5 As shown, this utility model provides a novel frequency converter that is easy to install, comprising:

[0027] The inverter body 1 has protrusions 15 fixedly connected to both sides, and a mounting back plate 5 is in contact between the back of the inverter body 1 and the back of the protrusions 15.

[0028] A baffle 4 is fixedly connected to the left end of the front surface of the mounting backplate 5. The right side of the baffle 4 contacts the left side of the inverter body 1. Guide frames 2 are fixedly connected to both ends of the front surface of the mounting backplate 5. The surface of the protrusion 15 is slidably connected to the surface of the guide frame 2.

[0029] A fixed frame 16 is fixedly connected to the right end of the guide frame 2. An insertion hole 9 is provided at the left end of the fixed frame 16. A limit stop frame 6 is slidably connected between the inner cavities of the two fixed frames 16. The right side of the inverter body 1 contacts the surface of the limit stop frame 6. Receiving grooves 13 are provided on both sides of the limit stop frame 6. An elastic plate 12 is fixedly connected to the right side of the receiving groove 13. A locking block 14 is fixedly connected to the left end of the elastic plate 12. The right side of the locking block 14 contacts the surface of the insertion hole 9.

[0030] In this technical solution, by installing the back plate 5, guide frame 2, and baffle 4, the inverter body 1 and the protrusion 15 can be limited vertically and to the left during installation. The limiting baffle 6 limits the right side of the inverter body 1, preventing displacement during use and thus achieving a secure installation of the inverter body 1. Simultaneously, the fixing frame 16, socket 9, locking block 14, and elastic locking plate 12 allow the locking block 14 to be inserted into the socket 9 on the fixing frame 16 under the action of the elastic locking plate 12, thereby limiting the movement of the limiting baffle 6 between the fixing frame 16 and the guide frame 2. To prevent the limit stop frame 6 from shifting and causing the inverter body 1 to loosen, and when it is necessary to disassemble the inverter body 1, the operator can press the elastic plate 12 to generate elastic deformation, causing the locking block 14 to disengage from the insertion hole 9 on the fixed frame 16 under the action of the elastic plate 12. Then, the operator can pull the limit stop frame 6 to the right to remove it from the inside of the fixed frame 16, and at the same time, slide the inverter body 1 and the protrusion 15 to the right along the guide frame 2 and the surface of the mounting back plate 5 to achieve the effect of quick disassembly of the inverter body 1. At the same time, the operator can quickly install the inverter body 1 by performing the above reverse operation.

[0031] It should be noted that the inverter body 1 is an existing technology, and its operating principle and internal circuit structure have not been changed.

[0032] Example 2:

[0033] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, the guide frame 2 has a positioning groove 8 at its right end, the surface of the limiting frame 6 is slidably connected to the surface of the positioning groove 8, the right side of the limiting frame 6 is fixedly connected to a pull rod 7, and there are two pull rods 7. The left side of the baffle 4 is fixedly connected to the left end of the front surface of the mounting back plate 5, and mounting holes are provided around the mounting back plate 5. The guide frame 2 is L-shaped, the fixing frame 16 is U-shaped, the right end of the fixing frame 16 has a through groove 11, and the middle end of the elastic plate 12 is fixedly connected to a pressing protrusion 10, the surface of the pressing protrusion 10 is in contact with the surface of the through groove 11.

[0034] In this technical solution, the positioning groove 8 can limit the movement between the guide frame 2 and the limiting stop frame 6, preventing displacement during the insertion of the limiting stop frame 6 and the guide frame 2. The pull rod 7 facilitates the pulling of the limiting stop frame 6 during disassembly. The reinforcing block 3 effectively improves the connection strength between the baffle 4 and the mounting back plate 5. The mounting hole facilitates the pre-installation and fixing of the mounting back plate 5 to the control cabinet. The through groove 11 and the pressing protrusion 10 facilitate the pressing of the elastic plate 12 during disassembly, while the pressing protrusion 10 is accommodated at the right end of the fixed frame 16 under the action of the through groove 11.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model.
