Description

Technical Field

[0001] This application relates to the field of fans. Specifically, it relates to a connection structure and a fan. Background Art

[0002] A fan is a machine that relies on the input mechanical energy to increase the gas pressure and pump the gas. It is a driven fluid machine. Generally speaking, fans include ventilators, blowers, and wind turbines. Fans are widely used for ventilation, dust removal, and cooling in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings, as well as for ventilation and induced draft in boilers and industrial furnaces.

[0003] Currently, the fastening components for fixing the fan and the mounting frame are studs and nuts. Although the overall equipment improves the heat dissipation effect of the fan, it is not conducive to the overall disassembly and assembly of the fan. When the fan itself is damaged or fails, the staff needs to disassemble its connecting parts one by one, resulting in a reduction in the disassembly and replacement efficiency of the fan. At the same time, it increases the disassembly and assembly workload of the staff, which is time-consuming and laborious.

[0004] Regarding this, Chinese Patent Application No. CN202321756996.X discloses a connection structure for the top plate of a fan. By pulling the pull rod, the push plate drives the insertion block to separate from the slot, so as to facilitate the removal of the fan body. At the same time, the pull rod can be loosened, and through the self-acting force of the return spring, the push plate drives the insertion block to connect with the slot, thus facilitating the installation and use of the fan body, improving the rapid and convenient disassembly and assembly of the equipment, reducing the disassembly and assembly workload of the staff, and saving time and effort.
