Description

Technical Field

[0001] This utility model relates to the field of fire safety technology, specifically a double-sealed plastic-coated composite steel pipe connection and positioning device. Background Technology

[0002] In fire protection piping systems, double-sealed plastic-coated composite steel pipes are widely used in key scenarios such as indoor and outdoor fire hydrant systems and automatic sprinkler systems due to their corrosion resistance, high pressure resistance, and aging resistance.

[0003] The device consists of a precision positioning module, a double sealing assembly, a locking mechanism, and an adapter adjustment unit. The device is fitted onto the end of the pipe to be connected, the laser alignment device calibrates the axis, the guide sleeve assists in pipe docking, the double sealing assembly fits the sealing surface after docking, the ring-type clamp is locked, and the torque wrench controls the locking force. After the connection is completed, the sealing performance is tested by pressure testing.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional connection and positioning devices mostly use bolts for single-point fixing, which cannot form all-round constraints from all sides of the pipe. The pipe is prone to axial displacement due to installation errors, and the double-seal structure cannot fit completely. In view of this, we propose a double-seal plastic-coated composite steel pipe connection and positioning device. Utility Model Content

[0005] The purpose of this utility model is to provide a double-sealed plastic-coated composite steel pipe connection and positioning device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A double-sealed plastic-coated composite steel pipe connection and positioning device includes a connecting pipe, with pipes attached to both sides of the connecting pipe, and a positioning component is provided on the connecting pipe, the positioning component comprising: A connector is fixedly installed on both sides of the connecting pipe. A connecting bracket is fixedly installed on the connector. A nut is fixedly installed on the connecting bracket on one side of the connecting pipe, and a screw is rotatably installed on the connecting bracket on the other side of the connecting pipe. A cylindrical tube is fixedly installed on the connector head. A groove is provided on the cylindrical tube. A threaded rod is rotatably installed on the cylindrical tube. A knob is fixedly installed on the threaded rod. The positioning block is threaded onto the threaded rod, which has an installation groove, and a spring is fixedly installed inside the threaded rod.

[0007] In a further embodiment, multiple sets of the connector, connecting bracket, nut, screw, cylinder, slide, threaded rod, knob, positioning block, mounting groove, and spring are provided.

[0008] In a further embodiment, the screw is threaded onto the nut, and the positioning block slides inside the groove.

[0009] In a further embodiment, the spring is disposed inside the mounting groove, and the other end of the spring is attached to the inner wall surface of the positioning block.

[0010] In a further embodiment, the connecting pipe is provided with an auxiliary component, the auxiliary component including a limiting groove, the limiting groove being formed inside the cylinder, a limiting block being fixedly installed on the positioning block, an anti-slip spike being fixedly installed on the positioning block, an installation ring being fixedly installed on the pipe, and a rubber ring being fixedly installed on the installation ring.

[0011] In a further embodiment, multiple sets of the limiting groove, limiting block, anti-slip spike, mounting ring, and rubber ring are provided.

[0012] In a further embodiment, the limiting block slides inside the limiting groove, and the positioning block and anti-slip spikes are positioned above the rubber ring.

[0013] Compared with the prior art, this utility model provides a double-sealed plastic-coated composite steel pipe connection and positioning device, which has the following advantages: 1. This double-sealed plastic-coated composite steel pipe connection positioning device, in order to reduce the sealing failure caused by positioning deviation, is equipped with a positioning component. This component works with the knob on the rotating cylinder to drive the threaded rod to move the positioning block along the slide groove. After the positioning block is in contact with the outer wall of the pipe, the spring in the mounting groove generates a reverse thrust, which enhances the tightness of the fit between the positioning block and the pipe and prevents the pipe from shifting. Multiple positioning units are symmetrically distributed on both sides of the connecting pipe to provide omnidirectional positioning from all sides of the pipe.

[0014] 2. The double-sealed plastic-coated composite steel pipe connection positioning device is equipped with an auxiliary component to meet the usage requirements of the double-sealed plastic-coated composite steel pipe. When the positioning block slides along the slide groove, the limiting block on the component slides synchronously along the limiting groove inside the cylinder, restricting the rotation of the positioning block and ensuring that the positioning block is always perpendicular to the outer wall of the pipe. This avoids positioning deviation from affecting the connection accuracy. After the positioning block is in contact with the pipe, the anti-slip spikes are embedded in the rubber ring on the outer wall of the pipe to increase friction and prevent the pipe from sliding under pressure or vibration.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

It is primarily used to better describe this application and its embodiments, and is not intended to limit the indicated device, element, or component to having a specific orientation, or to construct and operate in a specific orientation. Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0019] Please see Figures 1-6 This utility model provides a technical solution: A double-sealed plastic-coated composite steel pipe connection and positioning device includes a connecting pipe 1, with pipes 2 attached to both sides of the connecting pipe 1.

[0020] In one embodiment of this utility model, a positioning component 3 is provided on the connecting pipe 1. The positioning component 3 includes a connector 31, which is fixedly installed on both sides of the connecting pipe 1. A connecting bracket 32 ​​is fixedly installed on the connector 31. A nut 33 is fixedly installed on the connecting bracket 32 ​​on one side of the connecting pipe 1, and a screw 34 is rotatably installed on the connecting bracket 32 ​​on the other side of the connecting pipe 1. A cylinder 35 is fixedly installed on the connector 31. A groove 36 is provided on the cylinder 35. A threaded rod 37 is rotatably installed on the cylinder 35, and a knob 38 is fixedly installed on the threaded rod 37 for positioning. Block 39 is threaded onto threaded rod 37, which has a mounting groove 310. One end of spring 311 is fixedly installed inside threaded rod 37. Multiple sets of connector 31, connector 32, nut 33, screw 34, cylinder 35, slide groove 36, threaded rod 37, knob 38, positioning block 39, mounting groove 310 and spring 311 are provided. Screw 34 is threaded onto nut 33. Positioning block 39 slides inside slide groove 36. Spring 311 is located inside mounting groove 310. The other end of spring 311 is attached to the inner wall surface of positioning block 39.

[0021] In this embodiment, before connection, the connecting pipe 1 is placed between the two pipes 2, so that the two end faces of the connecting pipe 1 are initially attached to the mating end faces of the pipes 2, completing the pre-connection. Then, the operator rotates the knob 38 on the cylinder 35, causing the threaded rod 37 to rotate synchronously. Since the positioning block 39 is threadedly connected to the threaded rod 37 and cannot rotate due to the restriction of the sliding groove 36, the positioning block 39 slides along the sliding groove 36 towards the pipe 2. When the inner wall of the positioning block 39 is attached to the outer wall of the pipe 2, the knob 38 is further finely adjusted, and the threaded rod 37 is installed in the groove. The spring 311 inside 310 is compressed by the positioning block 39 and undergoes elastic deformation, forming a reverse thrust on the positioning block 39. This significantly improves the tightness of the fit between the positioning block 39 and the outer wall of the pipe 2, preventing the pipe 2 from radially shifting due to vibration or medium pressure. Multiple sets of positioning components 3 are symmetrically distributed along both sides of the connecting pipe 1. Each set of positioning blocks 39 applies positioning force from different directions around the pipe 2, forming an all-round positioning constraint. This ensures that the axes of the connecting pipe 1 and the pipe 2 are completely aligned, laying the foundation for the effective fit of the subsequent double-seal structure.

[0022] In one embodiment of this utility model, an auxiliary component 4 is provided on the connecting pipe 1. The auxiliary component 4 includes a limiting groove 41, which is opened inside the cylinder 35. A limiting block 42 is fixedly installed on the positioning block 39, and an anti-slip spike 43 is fixedly installed on the positioning block 39. An installation ring 44 is fixedly installed on the pipe 2, and a rubber ring 45 is fixedly installed on the installation ring 44. Multiple sets of limiting groove 41, limiting block 42, anti-slip spike 43, installation ring 44 and rubber ring 45 are provided. The limiting block 42 slides inside the limiting groove 41, and the positioning block 39 and anti-slip spike 43 are located above the rubber ring 45.

[0023] In this embodiment, as the positioning block 39 slides along the groove 36, the limiting block 42 on the positioning block 39 is simultaneously embedded into the limiting groove 41 inside the cylinder 35 and slides along the groove. The cooperation between the limiting groove 41 and the limiting block 42 strictly limits the movement trajectory of the positioning block 39, preventing the positioning block 39 from deflecting as the threaded rod 37 rotates. When the positioning block 39 is in contact with the outer wall of the pipe 2, the anti-slip spike 43 at the bottom of the positioning block 39 is precisely embedded in the rubber ring 45 on the mounting ring 44 of the pipe 2. The mechanical engagement between the anti-slip spike 43 and the rubber ring 45 increases the friction between the positioning block 39 and the pipe 2, preventing the pipe 2 from axially sliding under medium pressure fluctuations or external vibrations.
