DETAILED DESCRIPTION

[0022] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Example 1

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a current vector type inverter that is easy to assemble, including a current vector type inverter body 1 and a mounting seat 4, a mounting plate 2 is fixedly installed on the rear side of the current vector type inverter body 1, and a clamping strip 3 is fixedly installed on the left and right sides of the rear side of the mounting plate 2, and a limit groove 12 is provided on the surface of the clamping strip 3, and a clamping slot 7 is provided on the front and rear sides of the surface of the mounting seat 4. An assembly mechanism 6 is arranged on the inner side of the current vector type inverter body 1, and the assembly mechanism 6 includes a slide bar 601, a spring 602, a sleeve 603, a first connecting block 604, a connecting rod 605, a second connecting block 606, a partition 607, a positioning rod 608, a pull rod 609 and a handle 610, and the slide bar 601 is fixedly installed On the left and right sides of the inner cavity of the mounting seat 4, the sleeve 603 is slidably connected to the upper and lower sides of the surface of the slide bar 601, the spring 602 is fixedly connected to the inner side of the slide bar 601, and the other end of the spring 602 is fixedly connected to the surface of the sleeve 603. The first connecting block 604 is fixedly connected to the inner side of the sleeve 603, the connecting rod 605 is movably connected to the inner side of the first connecting block 604, the second connecting block 606 is fixedly connected to the outer side of the partition 607, the other end of the connecting rod 605 is movably connected to the inner side of the second connecting block 606, the positioning rod 608 is fixedly connected to the inner side of the partition 607, and the inner side of the slot 7 is provided with a positioning groove 5, and the other end of the positioning rod 608 extends to the inner side of the positioning groove 5 through the limit groove 12.

[0025] The provision of the assembly mechanism 6 can reduce the time for installation and configuration, thereby improving work efficiency, making maintenance and upgrading more convenient, and helping to reduce operating errors and improve the stability and reliability of the system. Example 2

[0026] In one embodiment, the pull rod 609 is fixedly connected to the outer side of the partition 607, the handle 610 is fixedly connected to the outer side of the pull rod 609, guide grooves 9 are opened on the upper and lower sides of the inner cavity of the positioning groove 5, guide blocks 8 are fixedly installed on the upper and lower sides of the partition 607, the guide blocks 8 are slidably connected to the inner side of the guide groove 9, and fixing plates 10 are fixedly installed around the surface of the mounting seat 4, and the surface of the fixing plate 10 is threadedly connected with mounting bolts 11.

[0027] The setting of the handle 610 can facilitate the installation personnel to grasp it. The setting of the guide block 8 and the guide groove 9 can play a guiding role to prevent the partition 607 from being offset during the movement. The setting of the fixing plate 10 and the installation bolts 11 can install the mounting base 4.

[0028] When the utility model is in operation: after the mounting base 4 is fixed by the fixing plate 10 and the mounting bolts 11, the handle 610 can be pulled outward, thereby driving the partition 607 to move outward. When the partition 607 moves, it will drive the positioning rod 608 and the second connecting block 606 to move outward. The movement of the second connecting block 606 will drive the connecting rod 605 and the first connecting block 604 to move outward. During the movement of the first connecting block 604, the sliding sleeve 603 will be driven to move outward. When the sliding sleeve 607 is moved, the positioning rod 608 and the second connecting block 606 will be driven outward. 03 During the movement, the spring 602 will be squeezed. At this time, after the card strip 3 is inserted into the inner side of the card slot 7, the handle 610 can be released. At this time, after the spring 602 loses the squeezing of the external force, it rebounds through its own tension and resets, thereby driving the first connecting block 604, the connecting rod 605, the second connecting block 606 and the partition 607 to move inward. When the partition 607 moves, it will drive the positioning rod 608 to pass through the positioning slot 5 and the limit slot 12, thereby completing the fixation of the current vector inverter body 1.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
