[0020] like Figures 1 to 7As shown, an interlocking combination structure of an explosion-proof fan comprises a cross-shaped main body support and stabilizing frame 1 made of metal material, and an integral cylindrical installation and fastening combination column 2 is provided at the center position of the lower end of the main body support and stabilizing frame 1, which is combined with the base at the bottom during installation and matching. A cylindrical fastening combination placement groove 4 is provided at the center position of the lower end of the installation and fastening combination column 2, which can be inserted and combined with the positioning structure on the base, ensuring that the operation during matching is more convenient. The inner side of the fastening combination placement groove 4 is provided with fastening limit matching holes 3 that are evenly distributed around the circumference and completely penetrate the outer side of the installation and fastening combination column 2, and fastening and matching are performed from the side. The fastening and matching operation between the base is more convenient, and the height of the fastening position can be adjusted as needed. A guiding stable connecting column 5 is provided at the outer side position of the upper end of the main body support and stabilizing frame 1, which can be guided and matched with the matching structure when combined with the explosion-proof fan, ensuring that the operation during matching is more convenient. This position is matched with the mounting hole position of the main shell. The cross-shaped structures in two opposite directions at the upper end of the main support and stabilization frame 1 are respectively provided with interlocking support connection columns 6 with the length direction facing the upper direction of the overall center. This position is connected with the fan assembly inside the explosion-proof fan. The central position of the interlocking support connection column 6 is provided with a cylindrical fastening combination connection hole 7 along the length direction of the central axis. The matching position can form a close matching effect with the position of the guide stable connection column 5. The fastening combination connection holes 7 at different positions form an interlocking match, which ensures that the overall combination stability is more reliable. It can be matched with the bottom of the main shell of the explosion-proof fan for matching connection when in use, and can be interlocked and matched with the components in two directions inside the explosion-proof fan. The lower end position can be combined with the bottom mounting frame, and the operation of the overall installation is more convenient. The interlocking assembly structure at the upper end position can ensure better connection stability, higher matching strength and stronger durability during later use, and more reliable combination firmness during installation. It has better anti-seismic effect during use, and avoids the situation where the matching position is easy to loosen.

[0021] Preferably, a limit anti-rotation matching groove is provided on the inner side of the fastening combination placement groove 4, so that the insertion combination stability when matched with the base is better and has a reliable anti-movement effect.

[0022] Preferably, the guide stabilizing connecting column 5 is connected to the main supporting stabilizing frame 1 in a detachable manner, so that this structure is more convenient during production and processing, with lower production costs, and different specifications of structures can be replaced during use as needed, which is more convenient during use.

[0023] Preferably, the cross-section of the interlocking support connecting column 6 is circular, so that the outer structure of this structure is safer.

[0024] Preferably, the width of the interlocking support connection column 6 is the same as the side width of the cross-shaped structure of the main support stabilizing frame 1, which can further improve the connection strength when the upper end position is matched.

[0025] 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 or substitutions can be made without departing from the principles of the present invention. These improvements or substitutions should also be regarded as the protection scope of the present invention.
