CN211739432U - I-shaped supporting connecting rod for reinforcing thin steel plate air pipe - Google Patents

Abstract

The utility model relates to a steel sheet tuber pipe consolidates I type supporting connection pole, the reinforcement screw among the current reinforcement mode, outstanding tuber pipe surface, its screw reinforcement leakproofness is poor, leaks gas, and the light leak supports intensity weak point. The utility model discloses a connecting rod, V type curved surface nut and crew cut countersunk head screw. The utility model discloses it flushes to coincide the top completely with crew cut countersunk head screw into V type recess and its characterized in that V type curved surface nut, the utility model discloses it is inseparable with screw and nut groove structure, and low in manufacturing cost, sealing performance is good, and is light-tight, airtight.

Description

I-shaped supporting connecting rod for reinforcing thin steel plate air pipe

The technical field is as follows:

thin steel plate ventilating duct.

Background art:

the inside of the thin steel plate ventilation pipeline is supported and reinforced.

The invention content is as follows:

the utility model relates to a steel sheet tuber pipe consolidates I type and supports connecting rod device, the reinforcement screw among the current reinforcement mode, outstanding tuber pipe surface, its screw reinforcement leakproofness is poor, leaks gas, and the light leak supports intensity weak point.

The utility model discloses a connecting rod V type curved surface nut and flat countersunk head screw. The utility model is characterized in that the nut is a V-shaped groove which is flush with the top of the flat countersunk head screw, the utility model discloses closely the screw and nut groove structure, and low in manufacturing cost, sealing performance is good, and is light-tight, and airtight.

Description of the drawings:

the present invention will be further described with reference to fig. 1.

FIG. 1 is a schematic view of the present invention;

in fig. 1: 1. a flat countersunk head screw, 2. a V-shaped curved surface nut, and 3. a connecting rod.

The specific implementation mode is as follows:

the hole is punched in the ventilation pipeline to support and reinforce, the reinforcing rod is arranged inside the air pipe, connecting nuts at two ends of the reinforcing rod use V-shaped curved surface nuts, the outer wall of the air pipe is screwed up by using flat-head countersunk head screws, and the screw stress thin steel plate air pipe is trapped in the supporting rod screws to reach the top end of the screw which is flushed on the outer wall of the air pipe.

As shown in fig. 1: two ends of the connecting rod (3) are connected with the flat-head countersunk head screw (1) through the V-shaped curved surface nut (2), the screw (1) is sunk inside the V-shaped curved surface nut (2) to form an inosculated veneering, and the upper edge of the V-shaped curved surface nut (2) is flush with the top of the flat-head screw (1).

Claims (2)

1. The utility model provides a thin steel sheet tuber pipe consolidates I type brace rod, its characterized in that includes connecting rod (3), V type curved surface nut (2) and flat-head countersunk screw (1), and the nut becomes V type recess and completely coincide with flat-head countersunk screw (1).

2. The thin steel plate air duct reinforcing I-shaped supporting and connecting rod as claimed in claim 1, characterized in that two ends of the connecting rod (3) are connected with the flat countersunk head screw (1) by adopting a V-shaped curved surface nut (2), the screw (1) is sunk inside the V-shaped curved surface nut (2) to form an inosculating veneer, and the upper edge of the V-shaped curved surface nut (2) is flush with the top of the flat countersunk head screw (1).
