Technical Field

The utility model relates to a malleation (discharge fume) air supply port technical field, in particular to high strength malleation air supply port.

Background

The positive pressure (smoke exhaust) air supply port is used for supplying air under pressure when a fire disaster happens, and the positive pressure (smoke exhaust) air supply port can continuously supply air to the front chamber, so that the front chamber maintains positive pressure, smoke is ensured not to spread in the area, and space for people to escape is provided.

The existing positive pressure (smoke exhaust) air supply outlet has the following defects that 1, the shell of the existing positive pressure (smoke exhaust) air supply outlet is formed by welding four shell plates, the welding is not environment-friendly and not attractive, the strength is lower than 2, and the support frame of the existing positive pressure (smoke exhaust) air supply outlet is also fixed at the center of the inner side of the shell through welding, so that the overlapped waste materials of plates can be formed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a high strength malleation supply-air outlet can solve the problem that points out among the background art.

The utility model provides a high strength malleation supply-air outlet, includes casing, blade, executor, panel door, support frame and fixed plate, the fixed plate is two parts about separating the casing, the latter half installation the blade, the blade with the executor transmission is connected, the executor is fixed on the fixed plate, the casing and fix the inboard support frame at the casing cut out, roll extrusion hem integrated into one piece through whole casing board.

Preferably, the two sides of the shell are provided with triangular convex blocks, and grooves matched with the triangular convex blocks are formed in the corresponding positions of the panel door.

Preferably, blind rivets are arranged on two sides of the shell.

Preferably, the shell and the inner support frame fixed on the shell are integrally formed by cutting and rolling the whole shell plate, and the interface of the shell and the inner support frame is riveted and fixed by a connecting piece.

The utility model provides a high strength malleation supply-air outlet, casing and fix the inboard support frame at the casing cut out, roll extrusion hem integrated into one piece through whole casing board, make it only have an interface, increased the bulk strength of casing, reduce the tie point, can also improve production efficiency, the tie point does not weld, make its environmental protection promptly pleasing to the eye again, disposable roll extrusion shaping support frame has reduced the plate thickness, has saved the material, has reinforceed holistic intensity.
