Description

Technical Field

[0001] This utility model relates to the field of building fire protection pipeline technology, specifically to a quick-connect clamp device for building fire protection pipelines. Background Technology

[0002] Building fire protection pipelines are special pipelines used in fire protection systems to connect fire protection equipment and transport fire extinguishing water, gas and other media. In fire protection pipeline systems, clamp connections are particularly suitable for fire protection pipelines with a diameter greater than 100 mm, which can be installed quickly while ensuring stability and sealing. This connection method uses grooved fittings (clamps) to tightly connect pipes together, which not only allows for rapid installation but also ensures the stability and sealing of the connection, providing strong protection for the safe operation of fire protection pipeline systems. A search revealed existing technology (announcement number: CN202321929374.2) for fire protection pipeline clamp connectors. The document states that "for situations where the outer bevel of the pipe flange has a concave defect, or where the outer bevel of the pipe flange cannot match the groove sidewall of the clamp connector, the required number and thickness of anti-slip elastic pressure plates can be filled in as needed. Corresponding matching anti-slip elastic pressure plates are retained on the groove sidewall of the clamp groove, and other unused anti-slip elastic pressure plates are removed. Then, the retained anti-slip elastic pressure plates are moved to the corresponding points where anti-slip elastic pressure plates need to be filled, and the target pipe flange is clamped using this clamp connector according to the existing operating method, improving the reliability of pipeline assembly." However, the existing technology requires multiple manual adjustments to the required number and thickness of anti-slip elastic pressure plates filled in the clamp, resulting in low connection and assembly efficiency. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, a quick-connect clamp device for building fire protection pipelines is provided to solve the problem that the required quantity and thickness of anti-slip elastic pressure plates filled into the clamps in existing technologies require multiple manual adjustments, resulting in low connection and assembly efficiency.

[0004] To achieve the above objectives, a quick-connect clamp device for building fire protection pipelines is provided, comprising: an upper clamp and a lower clamp, wherein the upper clamp is connected to the lower clamp via fixing bolts. The upper and lower clamps are welded to the front end faces with connecting ring blocks, and the connecting ring blocks are screwed with positioning studs. The inner groove walls at the front ends of the upper and lower clamps are connected to flange pressure blocks via spring blocks. The front end of the flange pressure block is connected to the front end walls of the upper and lower clamps via a limiting arc plate. The front end face of the limiting arc plate is supported and contacts the positioning studs. Elastic gaskets are distributed on the rear end of the flange pressure block.

[0005] Furthermore, both the upper and lower clamps are provided with extension protrusions on their left and right sides, and fixing bolts are connected through the surface of the extension protrusions.

[0006] Furthermore, the upper clamp and the lower clamp have limit grooves on their front ends; and the limit grooves are circumferentially distributed, with a limit arc plate passing through the limit groove.

[0007] Furthermore, sealing gaskets are fixed to the inner cavity walls of the upper and lower clamps, and the elastic gaskets are bonded to the inner groove walls at the rear ends of the upper and lower clamps.

[0008] Furthermore, a rubber gasket is bonded to the rear end face of the flange block, and a limiting arc plate is welded to the front end face of the flange block.

[0009] Furthermore, the flange pressure blocks are circumferentially distributed in the grooves of the upper and lower clamping parts, and a transparent protective semi-ring is fixed to the outer ring surface of the connecting ring block by a cable tie.

[0010] Furthermore, the inner side of the transparent protective semi-ring is in contact with the fire pipe surface through a rubber ring; and the transparent protective semi-ring is symmetrically covered on the outside of the positioning stud.

[0011] The beneficial effects of this utility model are as follows: the quick-connect clamp device for building fire protection pipelines utilizes the flange pressure blocks connected to the limiting arc plate and the groove surface of one side of the clamp to be distributed at the flange connection end of the fire protection pipeline. This allows the rebound block to elastically push multiple flange pressure blocks to press tightly against the flange surface of the fire protection pipeline. Then, rotating the positioning stud restricts the displacement of the flange pressure blocks in the tight-fitting state, facilitating quick adjustment of the clamp device to fully match and connect the building fire protection pipeline, reducing leakage caused by loose connections of the building fire protection pipeline, enhancing the contact pressure at the connection end of the building fire protection pipeline, ensuring a tight and secure connection and assembly of the building fire protection pipeline by the clamp device, and improving the debugging and assembly efficiency of the clamp device.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a quick-connect clamp device for building fire protection pipelines, including: an upper clamp 1 and a lower clamp 2, wherein the upper clamp 1 is connected to the lower clamp 2 by a fixing bolt 11. The front ends of the upper clamp 1 and the lower clamp 2 are welded with connecting ring blocks 31. The surface of the connecting ring blocks 31 is screwed with positioning studs 3. The inner groove walls at the front ends of the upper clamp 1 and the lower clamp 2 are connected to flange pressure blocks 4 through spring-loaded blocks 43. The front end of the flange pressure blocks 4 is connected to the front end walls of the upper clamp 1 and the lower clamp 2 through limiting arc plates 41. The front end of the limiting arc plates 41 is supported and contacted with positioning studs 3. Elastic gaskets 15 are distributed on the rear end of the flange pressure blocks 4.

[0018] First, pull the inner flange pressure block 4 of the upper clamp 1 and lower clamp 2 to press the spring block 43 into a holding state. Then, clamp the upper clamp 1 and lower clamp 2 one by one onto the flange end surfaces of the two sets of building fire protection pipes in the docking state, so that the elastic gasket 15 and the flange pressure block 4 are located on the side of the flange of the two sets of building fire protection pipes. At this time, the flange pressure block 4 in the groove of the upper clamp 1 and lower clamp 2 is pushed by the spring block 43 of deformation and moves to fit tightly against the flange surface of one side of the building fire protection pipe, so that the flange ends of the two sets of building fire protection pipes in the docking state are tightly fitted. Then, rotate the positioning stud 3 clockwise, so that the positioning stud 3 moves and presses against the limiting arc plate 41 at the front end of the flange pressure block 4, thereby limiting the displacement of the flange pressure block 4 in the tightly fitted state, increasing the contact pressure at the connection end of the building fire protection pipe, and ensuring that the clamp device is tightly and firmly connected and assembled with the building fire protection pipe, thus completing the connection and assembly of the clamp device.

[0019] In this embodiment, both the upper clamp 1 and the lower clamp 2 are provided with extending protrusions 12 on their left and right sides, and fixing bolts 11 are connected through the surface of the extending protrusions 12. Limiting grooves 13 are formed on the front end faces of the upper clamp 1 and the lower clamp 2; and the limiting grooves 13 are circumferentially distributed, with limiting arc plates 41 connected through the limiting grooves 13. Sealing gaskets 14 are fixed to the inner cavity walls of the upper clamp 1 and the lower clamp 2, and elastic gaskets 15 are bonded to the inner groove walls at the rear ends of the upper clamp 1 and the lower clamp 2.

[0020] In a preferred embodiment, the upper clamp 1 and lower clamp 2 are fixed together by the extending protrusion 12 and the fixing bolt 11, thus fixing the building fire protection pipeline within the clamp groove. The limiting groove 13 facilitates the horizontal movement of the flange pressure block 4 within the clamp groove, allowing the movable flange pressure block 4 to tightly fit against the uneven surface of the building fire protection pipeline flange. The sealing gasket 14 provides a tight seal at the connection of the building fire protection pipeline through elastic deformation. The elastic gasket 15 fits against the flange surface of a set of fire protection pipelines, forming a symmetrical fit with the flange pressure block 4.

[0021] In this embodiment, a rubber gasket 42 is bonded to the rear end face of the flange pressure block 4, and a limiting arc plate 41 is welded to the front end face of the flange pressure block 4. The flange pressure blocks 4 are circumferentially distributed in the grooves of the upper clamp 1 and the lower clamp 2, and a transparent protective half-ring 5 is fixed to the outer ring surface of the connecting ring block 31 by a cable tie. The inner side of the transparent protective half-ring 5 is in contact with the fire pipe surface through a rubber ring 51; and the transparent protective half-ring 5 is symmetrically covered and located outside the positioning stud 3.

[0022] As a preferred implementation, the limiting arc plate 41 facilitates the restriction of the displacement of the flange pressure block 4, preventing the flange pressure block 4 from shifting, while simultaneously being positioned and held in place by the positioning studs 3. Multiple flange pressure blocks 4, evenly distributed circumferentially, are uniformly and tightly pressed against the flange surface of the building fire protection pipeline, further enhancing the contact pressure at the connection end of the building fire protection pipeline and ensuring a tighter and more secure assembly connection between the upper clamp 1 and the lower clamp 2. The transparent protective semi-ring 5 serves to protect the positioning studs 3, preventing accidental contact with the positioning studs 3 from affecting their holding force.

[0023] This utility model of a quick-connect clamp device for building fire protection pipelines effectively solves the problem of low connection and assembly efficiency caused by the need for multiple manual adjustments to fill the clamps with the required quantity and thickness of anti-slip elastic pressure plates in existing technologies. It facilitates quick adjustment of the clamp device to fully match and connect building fire protection pipelines, reduces leakage caused by loose connections, enhances the contact pressure at the connection ends of building fire protection pipelines, ensures a tight and secure connection and assembly of building fire protection pipelines with the clamp device, and improves the adjustment and assembly efficiency of the clamp device. It is suitable for quick-connect clamp devices for building fire protection pipelines.
