Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

As shown in fig. 1 to 4, a flange connection structure includes a first flange 2 and a second flange 3, wherein a plurality of fasteners 4 are hinged on the first flange 2, and the plurality of fasteners 4 are circumferentially arranged along a central axis of the first flange 2 in an array manner; the second flange 3 is coaxially arranged with the first flange 2, and the end face of the second flange 3 is abutted against the end face of the first flange 2; the buckle 4 can be buckled on the outer periphery of the second flange 3 to limit the movement of the second flange 3.

In the present application, the first flange 2 and the second flange 3 may be fixed to two pipes, respectively, and the two pipes may be fixed together by the first flange 2 and the second flange 3.

In this application, can lean on second flange 3 and first flange 2 together, then manual a plurality of buckles 4 lock on first flange 2 on second flange 3 to make first flange 2 and second flange 3 fix together. Through the mode of buckle 4, can make first flange 2 and second flange 3 can be quick fixed connection together, it is all can more convenient when the installation with dismantle.

Because in this application, buckle 4's connected mode when adopting, second flange 3 is installed after can following its central axis arbitrary rotation for first flange 2, compares in traditional flange structure, needs aim at the screw in advance, has higher installation effectiveness, and is more convenient.

Specifically, the buckle 4 has a first limiting surface 41 and a second limiting surface 42, and the first limiting surface 41 and the second limiting surface 42 are arranged perpendicularly; the second flange 3 has an outer ring surface 31 and an inner side surface 32 far away from the end surface, the first limiting surface 41 abuts against the outer ring surface 31, and the second limiting surface 42 abuts against the inner side surface 32.

When a plurality of buckles 4 are buckled on the outer ring of the second flange 3, the first limit surface 41 abuts against the outer ring surface 31, and the second limit surface 42 abuts against the inner side surface 32, so that the second flange 3 can not move in any direction relative to the first flange 2.

The first limiting surface 41 and the second limiting surface 42 are vertically arranged and can be conveniently buckled.

Specifically, the buckle 4 can swing between a first position and a second position, and when the first position is adopted, the buckle 4 is buckled on the second flange 3, and when the second position is adopted, the first flange 2 and the second flange 3 are in a detachable state.

The first position is the complete snap-on engagement of the catch 4 on the outer ring of the second flange 3 and the second position is the complete disengagement of the catch 4 from the second flange 3.

In particular, the first flange 2 has a recess 21 and the second flange 3 has a projection 33, the projection 33 being able to snap into the recess 21. By the protrusion 33 in the second flange 3 snapping into the recess 21 of the second flange 3, the second flange 3 can be made immovable in a direction perpendicular to its central axis, thereby facilitating the mating of the second flange 3 and the first flange 2.

In this application, recess 21 is circular, and bulge 33 is because circular, and sets up with the axis coaxial of first flange 2, second flange 3 respectively.

Specifically, still include bandage 5, be equipped with spacing groove 43 on the buckle 4, bandage 5 sets up in the outer lane of second flange 3 and block in every spacing groove 43. After the buckle 4 is fastened on the second flange 3, all the buckles 4 are fastened by the binding bands 5, and the buckle 4 receives a force towards the direction along the central axis of the first flange 2, so that the possibility that the buckle 4 is separated from the second flange 3 is reduced.

Through setting up spacing groove 43, can reduce the possibility that bandage 5 breaks away from on buckle 4, improve the joint strength of first flange 2 and second flange 3.

Specifically, the limiting groove 43 is located on the side of the second flange 3 away from the first flange 2. This design enables the buckle 4 to be better buckled on the second flange 3 through the strap 5.

Specifically, still include bolt 6 and nut 7, the one end of bandage 5 is equipped with first connecting portion 51, and first connecting portion 51 is equipped with first through-hole, and the other end of bandage 5 is equipped with second connecting portion 52, and second connecting portion 52 is equipped with the second through-hole, and bolt 6 passes first through-hole, second through-hole and is connected with nut 7.

After the binding band 5 is bound to the plurality of buckles 4, the plurality of buckles 4 can be firmly bound by the binding band 5 by tightening the bolt 6 and the nut 7 to approach the first and second connection portions 52 of the binding band 5.
