Description

Flange plate with riveting structure

Technical Field

The utility model relates to an tuber pipe flange technical field specifically says a riveting structure's ring flange flowers.

Background

The air duct is a duct system for conveying and distributing air. There are two kinds of composite air pipe and inorganic air pipe. Composite air ducts are represented by the Durkduct air duct. They can be classified according to their sectional shapes and materials. The stainless steel air duct is made by coating sealing glue (such as neutral glass cement) on the seams such as seaming seam, rivet seam, flange flanging four corners, etc. Before the sealant is coated, dust and oil stains on the surface are removed. According to the cross section shape, the air pipe can be divided into a circular air pipe, a rectangular air pipe, an oblate air pipe and the like, wherein the circular air pipe has the smallest resistance but the largest height and size, and is complex to manufacture. So the application is mainly based on a rectangular air pipe. The air pipe can be divided into a metal air pipe, a composite air pipe and a polymer air pipe according to the material.

When the air pipes are installed, the air pipes need to be spliced, so that flange plates need to be installed at the spliced positions, and the two sections of air pipes can be fastened conveniently. The prior art at present is that operating personnel fixes the flange plate at the edge of the air pipe, and is not easy to detach. If the flange plate is not properly installed, the flange plate needs to be detached and installed again, so that the workload of workers is greatly increased, the machined air pipe is easily damaged and even scrapped, and the transportation is inconvenient.

SUMMERY OF THE UTILITY MODEL

Therefore, in order to solve the above insufficiency, the utility model provides a reasonable in design, simple structure, convenient to detach's a ring flange of riveting structure flowers here.

The utility model discloses a realize like this, construct a ring flange of riveting structure of blooming, including 4 group's flange strips, keep rotating the connection through the pin between the flange strip.

Furthermore, a groove B is formed in one side of the flange strip, and a through hole B is formed in the groove B.

Furthermore, the through hole B penetrates through the groove B and is arranged in the middle of the groove B.

Furthermore, a bulge is processed on the other side of the flange strip, and a through hole A is formed in the middle of the bulge.

Furthermore, the protrusion is in clearance fit with the groove B, and the position of the through hole A is matched with that of the through hole B.

Furthermore, a groove A is formed between the groove B and the protrusion.

Further, the groove A is matched with the edge of the air pipe.

Furthermore, a countersunk hole is formed above the groove A.

Furthermore, the through holes A and B which are not matched with the flange plate at the head and the tail are processed with threads.

The utility model has the advantages of as follows: reasonable in design, easy operation, convenient to detach has reduced operating personnel's work load. Through reasonable design flange strip, flange strip one side fluting B to open a through-hole B, through-hole B passes groove B, and place in groove B intermediate position, a arch is processed to flange strip opposite side, and a through-hole A is opened to protruding intermediate position, protruding and groove B clearance fit, and through-hole A coincide with through-hole B's position, the protruding and the groove cooperation of two flange strips, keep rotating the connection through the pin, four groups of flange strips surround the tuber pipe, make ring flange head and the tail fasten through the screw.

Reasonable design groove A, open a groove A between groove B and the arch, groove A cooperates with the tuber pipe border, and the installation of the ring flange of being convenient for when two tuber pipe ring flanges riveted, has increased the stability that the tuber pipe is connected, is difficult for droing.

The counter sink is reasonably designed, the counter sink is arranged above the groove A, and when the riveting is performed in a blooming mode, the expansion side is sunk into the counter sink, so that the phenomenon that the expansion bulge of the rivet cuts an operator is avoided, and the safety is improved.
