[0021] The embodiment of the present application provides an inverter that can be quickly disassembled. The main scheme is that limiting holes 11 are provided on the upper sides of both ends of the protective outer box 1, and locking components are provided on both ends of the inner side of the upper cover 9. The locking component includes a piston 12. When the upper cover 9 is inserted from top to bottom into the middle of the upper end of the protective outer box 1, the piston 12 is inserted into the limiting hole 11, thereby realizing the rapid installation and fixation between the upper cover 9 and the protective outer box 1. Conversely, the upper cover 9 can also be quickly disassembled, thereby providing convenience for the disassembly and maintenance of the inverter module 2.

[0022] Example 1: Reference Figure 1-4 As shown, a quickly disassembled inverter of the present embodiment includes a protective outer box 1 and an inverter module 2. The protective outer box 1 protects the inverter module 2. The inverter module 2 is fixedly mounted on the inner bottom of the protective outer box 1. An upper cover 9 is provided in the middle of the upper end of the protective outer box 1. The top of the protective outer box 1 can be sealed and covered by the upper cover 9, thereby protecting the top of the inverter module 2.

[0023] A locking assembly is provided at the inner top of the upper cover 9, including an installation box 13 and a piston 12. The installation box 13 is fixedly installed at the inner two ends of the upper cover 9, and the piston 12 is slidably installed in the inner middle part of the installation box 13. The head end of the piston 12 is arranged as an arc structure, and a spring 14 is arranged at the bottom of the piston 12. The spring 14 is fixedly installed in the inner middle part of the installation box 13; limiting holes 11 are provided on the upper sides of both ends of the protective outer box 1, and the piston 12 is inserted in the inner middle part of the limiting hole 11.

[0024] Among them, by setting the head end of the piston 12 as an arc-shaped structure, when the upper cover 9 is pressed downward, a compressive force will be generated on the piston 12, causing the piston 12 to move toward the inner side of the installation box 13. When the piston 12 moves to the position of the limiting hole 11, under the push of the elastic force of the spring 14, the head end of the piston 12 will be inserted into the limiting hole 11, thereby realizing the limiting fixation of the upper cover 9, thereby improving the stability of the fixed connection between the protective outer box 1 and the upper cover 9.

[0025] In addition, a limiting component is also arranged between the protective outer box 1 and the upper cover 9, including a limiting socket 8 and a limiting plug 10. The limiting socket 8 is located at the two ends of the inner side of the protective outer box 1, and the limiting plug 10 is located on both sides of the bottom end of the upper cover 9. The limiting plug 10 is inserted into the inner middle part of the limiting socket 8.

[0026] During the installation of the upper cover 9 , the limiting plug block 10 is inserted into the limiting socket 8 , so as to limit and fix the installation of the upper cover 9 , thereby preventing the bottom of the upper cover 9 from becoming loose.

[0027] In some examples, mounting frames 5 are provided on both sides of the bottom end of the protective outer box 1, and a plurality of mounting holes are provided in the inner middle of the mounting frames 5, so that the staff can use a plurality of fixing screws to install and fix the protective outer box 1 conveniently.

[0028] In some examples, a sealing plug is provided at the outer end of the limiting hole 11 to prevent external dust from accumulating in the limiting hole 11 and causing blockage.

[0029] The working principle of the utility model is:

[0030] By providing locking components at both ends of the inner side of the upper cover 9, it is convenient for the staff to quickly install or disassemble the protective outer box 1 and the upper cover 9, thereby facilitating the maintenance of the inverter module 2;

[0031] When the upper cover 9 needs to be installed, the upper cover 9 is first pressed downward from the upper end of the protective outer box 1 for insertion. During the insertion process, the piston 12 is inserted into the limiting hole 11, so as to achieve the role of limiting and fixing the installation of the upper cover 9. At the same time, by setting the limiting plug block 10 and the limiting socket 8, when the limiting plug block 10 is inserted into the limiting socket 8, the bottom of the upper cover 9 is limited and fixed, and the stability of the installation of the upper cover 9 is further improved.

[0032] On the contrary, when the upper cover 9 needs to be removed, it is only necessary to insert a rod into the limiting hole 11 to push the piston 12, so that the connection between the piston 12 and the limiting hole 11 is disconnected, and the limiting of the piston 12 is lost. The upper cover 9 can be quickly removed by only pushing it upwards.

[0033] Example 2: Reference Figure 1-4 As shown, based on Embodiment 1, a quickly disassembled inverter further includes the following structure:

[0034] A heat dissipation component is provided on the back of the protective outer box 1, including two groups of heat dissipation fans 7. The two groups of heat dissipation fans 7 are fixedly installed on both sides of the back of the protective outer box 1. By operating the two groups of heat dissipation fans 7, the flow speed of the air inside the protective outer box 1 can be accelerated, thereby playing a role in ventilation and heat dissipation. A protective net is also provided on the outer side of the heat dissipation fan 7 to protect the heat dissipation fan 7.

[0035] The heat dissipation component also includes multiple groups of ventilation holes 6, which are distributed in an array and located on the lower front side of the protective outer box 1. The ventilation holes 6 allow the air inside the protective outer box 1 to circulate with the outside air, achieving the effect of ventilation and heat dissipation.

[0036] The inner bottom of the protective outer box 1 is provided with a mounting plate 3, and the inverter module 2 is fixedly mounted on the middle of the upper end of the mounting plate 3. In addition, the bottom of the inverter module 2 is connected with a heat dissipation fin 4 through a heat-conducting aluminum sheet, and the end of the heat dissipation fin 4 passes through the bottom of the protective outer box 1 and extends out, further improving the efficiency of heat dissipation and cooling.

[0037] Through the above structure, good ventilation and heat dissipation effect is achieved for the inverter module 2.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
