Detailed Description

The thin-wall baffle structure applied to the blow-molding air duct of the present invention will be further described below with reference to specific embodiments to help those skilled in the art understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 4 to 6, the thin-walled baffle structure applied to the blow-molded air duct of the embodiment includes a blow-molded air duct 10 and a thin-walled baffle 20. Blow molding wind channel 10 includes intake stack 11, air-out pipeline 13, and sets up and be in between intake stack 11, the air-out pipeline 13 and connect intake stack 11, the crooked linkage segment 12 of air-out pipeline 13, intake stack 11, crooked linkage segment 12 and air-out pipeline 13 are the integrated into one piece structure. The bending connection section 12 is provided with fixing grooves, the front end and the rear end of each fixing groove extend to the air inlet pipeline 11 and the air outlet pipeline 13, the upper end and the lower end, opposite to each fixing groove, of each fixing groove protrude out of the two opposite surfaces of the blow molding air duct 10 respectively to form a V-shaped protruding portion 15, one V-shaped protruding portion 15 is provided with a cutting opening 14, the thin-wall guide plate 20 is inserted into the fixing grooves through the cutting openings 14, and the thin-wall guide plate 20 and the cutting openings 14 are fixed through hot melting welding. The V-shaped protrusions 15 formed by the two opposing surfaces may have different or the same height, and the cutting opening 14 is provided on the V-shaped protrusion 15 having the higher height of the two V-shaped protrusions 15.
