Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a snap-on fire-fighting rigid clamp. Background Technology

[0002] In fire protection systems, reliable pipe connections are crucial. Fire-resistant rigid clamps, as key connecting components, play an indispensable role. They not only ensure the sealing and stability of the fire protection piping system, but also play an important role in ensuring the smooth delivery of fire-fighting water or other fire extinguishing media during a fire. When the fire protection system is activated, the water pressure in the pipe can rise instantly from 0 to over 10MPa, generating a water hammer effect and a peak load on the clamps. If the fasteners are not designed according to impact loads, instantaneous displacement is likely to occur.

[0003] In existing technologies, screws are added for fixing. The screws generate axial tension and radial friction through the engagement of the threads and the screw holes, which can simultaneously constrain the axial displacement and circumferential rotation of the connected parts. In fire-fighting rigid clamps, the screws are tightened evenly to press the clamps onto the pipes, and the self-locking property of the threads is used to prevent the clamps from shifting momentarily due to water pressure impact.

[0004] While screw fixing solves the problem of instantaneous displacement, the screw fixing process is more complicated and time-consuming, and repeated disassembly can cause wear on the screw holes. If a snap-on fixing is used, there is no need to drill holes or tighten screws. It can be operated with one hand, has high installation efficiency, can be repeatedly disassembled, and causes less damage to the workpiece surface after disassembly, making it more suitable for firefighters. Summary of the Invention

[0005] The purpose of this utility model is to provide a snap-on fire-fighting rigid clamp, which solves the problems of the existing technology where screw fixing involves many steps, is time-consuming, and causes wear on the screw holes due to repeated disassembly.

[0006] To achieve the above objectives, this utility model provides a snap-on fire-fighting rigid clamp, including a semi-circular block one, a semi-circular block two provided on the rear side of the semi-circular block one, and a fixing mechanism provided on both the left and right sides of the semi-circular block one. The fixing mechanism is used to connect the pipe. A positioning component is provided inside both the semi-circular block one and the semi-circular block two. The positioning component is used to position and seal the pipe.

[0007] The fixing mechanism includes two fixing plates, the left sides of the two fixing plates are fixedly connected to the left and right sides of the semicircular block, the left and right sides of the semicircular block are fixedly connected to fixing plates, a reset component is provided on the right side of the inner wall of the fixing plate, a rotating component is provided on the front side of the fixing plate, a locking component is provided inside the rotating component, and hollow grooves are provided on the front and rear sides of the fixing plate.

[0008] The positioning component includes a limiting plate, the outer wall of which is fixedly connected to the middle of the inner wall of the first semicircular block, a positioning plate is provided on the top of the limiting plate, a sealing component is provided on the inner wall of the first semicircular block, and screws are threadedly connected to the left and right sides of the outer walls of the first and second semicircular blocks.

[0009] The rotating assembly includes a rotating column, the rear end of which is rotatably connected to the front center of the fixed plate, and the front end of which is fixedly connected to a fixed column.

[0010] The engaging assembly includes a spring, with the left side of the spring fixedly connected to the inner wall of the rotating column, and the right end of the spring fixedly connected to a locking pin.

[0011] The reset assembly includes a reset post, the outer wall of which is slidably connected to the inner wall of a fixing plate, a circular hole is provided on the right side of the fixing plate, and a baffle is fixedly connected to the outer wall of the reset post.

[0012] The sealing assembly includes a sealing ring, the top of which is fixedly connected to the bottom of the limiting plate, and a sealing plate is fixedly connected to the front side of the fixing plate.

[0013] The screw has a washer on its outer wall, and the top of the outer wall of the washer is threaded to the outer wall of the limiting plate.

[0014] The right end of the reset post is fixedly connected to a fixing block, and the inner wall of the circular hole is slidably connected to the outer wall of the locking post.

[0015] This utility model discloses a snap-on fire-fighting rigid clamp. By aligning semicircular blocks one and two, the fixing post passes through the hollow groove. Rotating the fixing post drives the rotating post. When the fixing post is horizontal, a spring will spring the locking post into the circular hole. A baffle prevents the reset post from fully ejecting, thus fixing the second fixing plate and the first fixing plate. For disassembly, pressing the reset post causes the locking post to enter the rotating post, and rotating the fixing post separates the two fixing plates. This enables the installation and disassembly of the equipment, facilitating use by firefighters and improving pipeline installation efficiency.

[0016] By tightening the screws to pass through the second semicircular block and the limiting plate, the two are fixed together. Sealing rings are installed at the upper and lower ends of the limiting plate. Then, the pipe is slid between the first and second semicircular blocks until it contacts the limiting plate. The pressure of the pipe will cause the sealing rings to fill the gap between the pipe and the equipment. At the same time, the sealing plate seals the gap between the second fixing plate and the first fixing plate, thereby achieving the sealing and limiting of the equipment. This makes the pipe installation faster and greatly improves the sealing performance of the equipment. Attached Figure Description

[0037] Working principle: Align semicircular block 1 and semicircular block 2 with the fixing posts 2062 on both sides so that they pass through the hollow groove 203. Rotate the fixing post 2062, which will drive the rotating post 2061 to rotate together. When the fixing post 2062 rotates to the horizontal position, the spring 2041 will pop out the locking post 2042 and put it into the round hole 2052, thereby popping the reset post 2051 out from the inner wall of the round hole 2052. The baffle 2053 can prevent the reset post 2051 from being completely popped out, thus fixing the fixing plate 202 and the fixing plate 1 201. When disassembly is required, press the reset post 2051 so that the locking post 2042 re-enters the rotating post 2061, and rotate the fixing post 2062 to separate the fixing plate 202 and the fixing plate 1 201. This realizes the installation and disassembly of the equipment, which is convenient for firefighters and improves the installation efficiency of pipelines.

[0038] Tighten screw 304 so that it passes through semicircular block 2 4 and limiting plate 301, thus fixing semicircular block 2 4 and limiting plate 301 together. Then place sealing rings 3031 on the top and bottom of limiting plate 301. Slide the pipe along the inner wall of positioning plate 302 into the interior of semicircular block 1 and semicircular block 2 4. Stop when it hits limiting plate 301. Under the pressure of the pipe, sealing ring 3031 can fill the gap between the pipe and the equipment, while sealing plate 3032 can fill and seal the gap between fixing plate 2 202 and fixing plate 201, thereby achieving sealing and limiting of the equipment, making the pipe installation faster and greatly improving the sealing performance of the equipment.
