Technical Field

[0001] The present application relates to the field of fire protection pipes, and in particular to a fire protection pipe connector. Background Art

[0002] Fire protection pipes are an important part of the fire protection system. When installing fire protection pipes, the clamp butt connector is an important component used to connect the fire protection pipes. The clamp butt connector is mainly composed of a clamp, a rubber sealing ring and a connecting groove. A groove of a certain depth and width is processed at the end of the pipe by a grooving machine and other equipment, and then the rubber sealing ring is placed at the butt joint of the two pipes. Finally, the two pipes are tightened with a clamp and bolts.

[0003] When the clamp fixes the sealing ring on the pipe, the two clamps that are hinged to each other are generally clamped on the outer surface of the pipe, and then the edges are tightened with bolts. However, when the bolts control the clamps to squeeze the sealing ring against each other, the two clamps are close to each other, and the main squeezing parts are concentrated in the middle position of the clamps, while the sealing ring near the hinge and edge of the clamp is squeezed less, resulting in a certain difference in the overall pressure effect of the outer surface of the sealing ring, which in turn has a certain impact on the connection sealing between the pipes and reduces the overall use efficiency of the pipe connector.

[0004] In view of the above-mentioned related technologies, the inventor believes that the fire pipe connector has the defect of uneven pressure effect on the overall sealing ring when in use. Therefore, a fire pipe connector is proposed to solve the above problem. Utility Model Content

One side of the inner wall of the fastener 7 abuts against the outer surface of the sealing card gasket 3, and a fixing groove 8 is opened in the middle of one side of the outer surface of the movable card sleeve 5. The fixing groove 6 and A guide slot 9 is provided between the fixed grooves 8. The outer surface of the movable sleeve 5 is placed inside the fixed groove 8 and a limiting ring 10 is provided. A plurality of limiting blocks 11 are welded on the middle part of one side of the inner wall of the limiting ring 10. The middle part of one side of the inner wall of the limiting ring 10 is located inside the fixed groove 8. The outer diameter of the limiting block 11 is smaller than the distance between the two sides of the inner wall of the guide slot 9. One end edge of the limiting block 11 passes through the guide slot 9 and abuts against the outer surface of the fastener 7. The guide slot 9 and the limiting block 11 are engaged with each other. A fastening mechanism is also provided on the outer surface of the sealing gasket 3 for fixing the sealing gasket 3 to the outer surface of the pipe body 1.

[0022] By sleeve-and-clamping the sealing gasket 3 at the intersection of the two pipe bodies 1, the movable sleeve 5 is moved along the outer surface of the sealing gasket 3 to the position of the hoop 2, and the limiting ring 10 is rotated to move along the inside of the fixed groove 8, so that the limiting ring 10 drives multiple limiting blocks 11 to move along the inside of the guide slide groove 9, and the limiting blocks 11 push the fasteners 7 to rotate outward along the inside of the fixed groove 6, so that multiple fasteners 7 are moved and squeezed on the outer surface of the sealing gasket 3, so that the sealing gasket 3 is sealed and fitted on the outer surface of the pipe body 1, and the hoop 2 and the limiting groove 4 are tightly attached to each other, reflecting the limiting and squeezing effect of multiple fasteners 7 on the outer surface of the sealing gasket 3.

[0023] Reference Figure 1 and Figure 2The fastening mechanism includes a fastening clamp 12, which is symmetrically clamped on the outer surface of the sealing gasket 3. A bearing seat 13 is installed between the two fastening clamps 12 near one side edge for mutual rotation. A connecting plate 14 is welded to the other side edge of the fastening clamp 12.
