DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0023] In the embodiment, refer to Figures 1-4The utility model provides a kind of frequency converter of convenient disassembly, including shell 1 and frequency converter main body 2, the top of shell 1 has cover 16, frequency converter main body 2 is inserted in shell 1 from top to bottom, both sides inner wall of shell 1 are respectively opened out heat dissipation air hole 3, heat generated when frequency converter works is dissipated outward through heat dissipation air hole 3.

[0024] The inside bottom of shell 1 is provided with base 4, and the bottom of frequency converter main body 2 is provided with support plate 5 inserted into both sides of base 4.

[0025] The inside of base 4 is provided with gear 6 at front and back respectively, and the two gears 6 are kept coaxial rotation through a connecting shaft 10, and the upper and lower sides of the two gears 6 are respectively provided with sliding plate 8 kept meshing transmission.

[0026] Combining with the accompanying Figure 3 The sliding plate 8 is L-shaped structure plate, and the plate surface of the sliding plate 8 towards gear 6 is provided with rack 81 meshing with gear 6. In addition, the inside of base 4 is opened out sliding cavity 7 for sliding plate 8 to slide. The two gears 6 rotate synchronously, so that, with the rotation of gear 6, four sliding plates 8 will be simultaneously slid outwards along sliding cavity 7.

[0027] The outside of sliding plate 8 is provided with positioning column 9, which slides outwards from the inside of base 4 and is inserted into the positioning hole pre-opened on the outside support plate 5, and the four positioning columns 9 are used to fix the support plate 5 of frequency converter main body 2, so as to ensure the installation of frequency converter main body 2.

[0028] The connecting shaft 10 penetrates through the outside of shell 1 and extends straight outside shell 1, and the outer end of connecting shaft 10 is respectively provided with a push arm 11. The push arms 11 on both sides of shell 1 rotate coaxially, as shown in the accompanying Figure 2 The front and back of shell 1 are respectively provided with fixing seat 13 directly below the shaft end of connecting shaft 10, spring 14 is installed on fixing seat 13, and the other end of spring 14 is fixed on the arm lever of push arm 11. Spring 14 has elastic force, and in this embodiment, the vertical line is the central axis of shell 1.

[0029] When push arm 11 is on the right side and stretches spring 14 outwards, spring 14 has elastic potential energy, and when push arm 11 is pushed from right to left, the elastic potential energy of spring 14 needs to be overcome, and the relative fixation between assembled frequency converter main body 2 and shell 1 can be maintained by the elastic potential energy of spring 14, so as to ensure that the position of frequency converter main body 2 is unchanged, and the rapid assembly is completed.

[0030] When the arm 11 crosses the center axis of the shell 1 and is pushed to the left, on the one hand, the internal gear 6 will rotate reversely and simultaneously withdraw the four positioning columns 9 into the base 4, so that the foot plate 5 is released from the restriction of the positioning columns 9, facilitating the quick disassembly of the frequency converter main body 2; on the other hand, the spring 14 still has the elastic potential energy of being stretched, so that the positioning columns 9 can be maintained in the position inside the base 4, and after the frequency converter main body 2 is repaired, it is convenient to quickly assemble it into the shell 1.

[0031] Finally, it needs to be supplemented that the surface of the shell 1 is symmetrically arranged with the limiting columns 12 on both sides of the arm 11, and the design purpose of the limiting columns 12 is to ensure the limitation of the swinging angle of the arm 11, so that the arm 11 can only rotate within a reasonable angle range; at the same time, the end of the arm 11 is provided with a pushing block 15, and the design purpose of the pushing block 15 is to facilitate manual disassembly and assembly, which is more convenient to operate.

[0032] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
