Description

Technical Field

[0001] The utility model relates to a flange component that is easy to connect, in particular to a flange component that is easy to connect, and belongs to the technical field of flanges. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as a reducer flange.

[0003] The flanges of the prior art have the following disadvantages: 1. Flanges are often connected by bolts, which are prone to sliding during fixation, causing the screw holes to shift, and it takes a long time to tighten multiple bolts, making the connection inconvenient; 2. After the pipeline is connected by the flange, liquids such as water in the pipeline are prone to leak from the gaps between the flanges during continuous transportation. After long-term use, the flanges become loose, causing a large amount of liquid to leak, resulting in certain property losses. Therefore, improvements are made to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a flange assembly that is easy to connect in order to solve the above-mentioned problem. The connection frame, the block, the convex frame and the like can make the flange a and the flange b be quickly connected, and the installation is convenient; the airbag and the expansion water-stop rubber can improve the overall anti-leakage ability between the flanges.

[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a flange assembly that is easy to connect, including flange a, wherein flange a is fixedly connected to a connecting frame, a slide is slidably connected to the connecting frame, a spring b is installed in the slide, a clamping block is installed in the spring b, the connecting frame is threadedly connected to a rotating frame, the connecting frame is snap-connected to flange b, the flange a and flange b are both fixedly connected to a pipeline, a connecting pipe is bonded in the pipeline, the connecting pipe is fixedly connected to a telescopic tube, the telescopic tube is fixedly connected to an airbag, the air inlet of the airbag extends to the interior of the trachea, and the flange a and flange b are both provided with a step groove, and an expandable water-stop rubber is bonded in the step groove.

[0006] Preferably, the block is slidably connected to a slide, the slide is located on the left side of the spring a, and the spring a is installed with a flange a.

[0007] Preferably, the connecting frame buckle is connected with a clamping hole, and the clamping hole is opened on the surface of the flange b.

[0008] Preferably, the air pipe is equipped with an air nozzle, and the air bag is located inside the pipe.

[0009] Preferably, the flange b is fixedly connected to the boss a, and the boss a is slidably connected to the boss b.

[0010] Preferably, the boss b is fixedly connected to the flange a, the flange a is provided with a slide groove a, and the slide groove a is slidably connected to the boss a.

[0011] Preferably, the flange b is provided with a slide groove b, and the slide groove b is slidably connected with a protrusion b.

[0012] The beneficial effects of the utility model are:

[0013] The connection frame, the clamping block, the convex frame and the like can be used together to quickly connect the flange a and the flange b, and the installation is convenient. When installing between the flanges, the flange is moved so that the convex frame b on the flange a corresponds to the convex frame a on the flange b. The flange a is pushed so that the convex frame b on the flange a continues to slide along the convex frame a. The convex frame can guide the moving direction of the flange. The connection frame on the flange a is gradually inserted into the clamping hole provided on the flange b. After the connection frame gradually enters the clamping hole, it squeezes the clamping block. The clamping block slides inward along the connection frame and the slide frame to compress the spring b. The connection frame is fully inserted. After entering the card hole, there is no pressure on the outside, and the compressed spring b pushes the card block to move outward and get stuck behind the card hole. Rotating the rotating frame on the connecting frame can push the slide to move right, so that the card block in the slide is close to the card hole, so that flange a and flange b are close together. After the connecting frame enters the card hole, the convex portion b on flange a enters flange b along the sliding groove b opened on flange b, and the convex portion a on flange b slides into the outside of flange a along the sliding groove a opened on flange a, which can further fix the position of the flange, and the two flanges can be quickly installed through the connecting frame, the card frame, the convex portion, the etc.

[0014] The cooperation of the airbag and the expansion water-stop rubber can improve the overall anti-leakage ability between the flanges; the inner sides of flange a and flange b are provided with step grooves, and the expansion water-stop rubber is installed in the step grooves. After being immersed in water, the volume of the airbag expands to achieve the effect of water-stopping. When the liquid leaks, it can absorb water and expand to fill the gap to achieve the effect of water-stopping. Flange a and flange b are both connected to the pipeline. The connecting pipes at both ends of the telescopic tube are bonded to the inside of the pipeline, and airbags are provided on both sides of the telescopic tube. The airbags are located between the pipeline and the telescopic tube. When the two flanges are connected, the telescopic tube is squeezed to compress it. The telescopic tube is located inside the two flanges. After the flanges are installed, the air pipe connected to the air nozzle is used to inflate the two airbags. After the airbags are filled with air, they gradually swell up, which can fill the gap between the pipeline and the telescopic tube and fix it in the pipeline. When the liquid in the pipeline moves, it moves to the pipeline on the other side through the telescopic tube. After a gap is generated between the two flanges or the connection is loose, the telescopic tube can connect the two pipelines to avoid direct outflow of the liquid in the pipeline, thereby achieving the effect of anti-leakage.
