[0002] With more and more electrical equipment nowadays, electricity is an indispensable and important part in both life and production, and many products are designed and produced based on electricity. Now, in order to better control electricity, many improvements have been made on switching power supplies. The switching power supply has a shell structure, which mainly protects the switching power supply.

[0003] At present, the shell of the switching power supply is mostly connected by screws. When the internal components of the shell of the switching power supply need to be replaced and repaired, it takes a lot of time to remove the screws on the outside of the shell of the switching power supply, which increases labor and reduces work efficiency. At the same time, dust will adhere to the outside of the heat dissipation holes on the outside of the existing switching power supply shell after long-term use, which will cause the heat dissipation holes to be blocked, affecting the heat dissipation and affecting the use of the device. Therefore, a shell structure of a switching power supply is proposed to solve the above-mentioned technical problems. Utility Model Content
