[0027] The use of the utility model:

[0028] First of all, it should be made clear that the fixed structure involved in the utility model is arranged on the controller housing of the compressor and the quick disassembly and fixing operation of the PVC board inside the controller housing. It should be noted that the various parts of the fixed structure are made of plastic. The utility model takes the installation and disassembly of the controller housing of the compressor and the PVC board inside the controller housing as an example to explain its usage in detail. When it is necessary to install the PVC board inside the controller housing, first push the upper housing 102 outward to separate it from the lower housing 101. Since the upper housing 102 and the lower housing 101 are both plastic structures with a certain toughness, the wedge-shaped block 208 and the wedge-shaped slot 205 as well as the card plate 206 and the fixing slot 207 will separate from each other under the action of their own deformation ability and external force, thereby realizing the disassembly operation of the upper housing 102 and the lower housing 101, and then the PVC board and the wires are put in. The wires are connected to each other through the fixing tube 202 and passed through the wire threading hole on the clamping plate 206, and then the PVC board is inserted into the baffle 300, and then the upper shell 102 and the lower shell 101 are clamped together to realize the installation of the PVC board inside the controller shell. When the PVC board inside the controller shell needs to be disassembled and repaired, the upper shell 102 and the lower shell 101 are first separated in the same way as the operation during installation, and then the PVC board inside the controller shell can be disassembled and repaired. The utility model can realize the rapid disassembly and assembly of the lead-out wires on the PVC board of the controller shell through the quick-change fixing component 200, and can meet the fixing requirements of a variety of different PVC board lead-out wires. There is no need to prepare multiple different types of controller shells, which avoids the problem that the self-tapping screws may cause the terminal posts at the connection to break, greatly improving the service life of the controller shell.

[0029] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
