Description

Technical Field

[0001] This application relates to the field of pipe connection auxiliary tools, and in particular to a pipe thread guide alignment tool. Background Technology

[0002] Threaded connections are a common method of pipe installation, offering advantages such as reliable connection and easy disassembly. However, in practice, besides the difficulty in quickly and accurately aligning the center axes of the two pipes to be connected, leading to issues like "thread jamming" and "thread stripping," there are also key problems such as a lack of anti-loosening warnings and insufficient tool portability and heat dissipation, which seriously affect construction quality and efficiency.

[0003] Currently, construction workers typically rely on experience to manually adjust pipe positions and tighten alignment tools. Existing simple alignment tools not only suffer from low alignment accuracy and poor versatility, but also lack effective anti-loosening monitoring mechanisms. The clamping adjustment structure of these tools is prone to loosening after construction vibrations or prolonged use, leading to alignment failure that is difficult for operators to detect in real time. This can result in thread misalignment, decreased connection sealing, and even pipe leaks. Furthermore, existing tools often employ solid or thick-walled designs without considering weight reduction, especially in high-altitude or frequently moving work scenarios, where excessive tool weight significantly increases the labor intensity of carrying and operating them. In addition, the friction between the pipe and the alignment tool's guide structure during engagement generates a large amount of heat. Existing tools lack dedicated heat dissipation designs, and heat accumulation can cause aging and deformation of guide components, shortening tool lifespan. Operating at high temperatures also increases safety risks for construction workers.

[0004] Therefore, this application proposes a pipe thread guide alignment device. Utility Model Content

[0005] This application proposes a pipe thread guide alignment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A pipe thread guide alignment device includes a guide seat, an adjustment component, a positioning component, a guide auxiliary component, a limiting component, an anti-loosening warning component, and a weight reduction and heat dissipation structure. The guide seat is a hollow cylindrical structure. Both ends of the guide seat are respectively provided with positioning ports for fitting the pipe to be connected. The axis of the positioning port coincides with the central axis of the guide seat.

[0008] The adjustment components are symmetrically arranged on the outer side wall of the guide seat. The adjustment components include an adjustment rod and an adjustment block. A threaded hole adapted to the adjustment rod is opened on the side wall of the guide seat. The adjustment rod passes through the threaded hole and extends into the interior of the guide seat. One end of the adjustment rod located inside the guide seat is rotatably connected to the adjustment block.

[0009] The anti-loosening warning component is installed at the connection between the adjusting rod and the guide seat. The anti-loosening warning component includes a warning spring, a warning plate and a warning color layer. The warning spring is sleeved on the adjusting rod outside the guide seat. One end of the warning spring abuts against the outer wall of the guide seat, and the other end is fixedly connected to the warning plate. The warning plate is sleeved on the adjusting rod and threadedly connected to the adjusting rod. The warning color layer is coated on the side of the warning plate facing the guide seat.

[0010] The weight-reducing and heat-dissipating structure includes weight-reducing holes on the side wall of the guide seat and heat dissipation grooves on the inner wall of the guide sleeve. The weight-reducing holes are evenly distributed along the circumference of the guide seat, and the heat dissipation grooves are opened along the axial direction of the guide sleeve and communicate with the outside.

[0011] In a preferred embodiment, the adjusting block has an arc-shaped structure, and an anti-slip pad is provided on the arc-shaped inner sidewall of the adjusting block;

[0012] In a preferred embodiment, the positioning assembly includes a positioning ring and a positioning bolt. The positioning ring is sleeved on the outer sides of both ends of the guide seat, and a positioning hole is provided on the side wall of the positioning ring. The positioning bolt passes through the positioning hole and abuts against the outer side wall of the guide seat.

[0013] In a preferred embodiment, a guide sleeve is provided on the inner wall of the positioning ring. The guide sleeve is coaxially arranged with the positioning port, and the inner diameter of the guide sleeve is adapted to the outer diameter of the pipe to be connected.

[0014] In a preferred embodiment, the guiding auxiliary component includes a fixed seat and a guide ball. The fixed seat is fixedly connected to the inner wall of the guide seat, and the guide ball is rotatably mounted on the fixed seat. The outer wall of the guide ball contacts the threaded end face of the pipe to be connected.

[0015] In a preferred embodiment, the limiting component includes a limiting spring and a limiting block. An installation groove is provided on the inner side wall of the guide seat. One end of the limiting spring is fixedly connected to the bottom of the installation groove, and the other end of the limiting spring is fixedly connected to the limiting block. The limiting block has an arc-shaped structure and is adapted to the outer wall of the pipe to be connected.

[0016] The beneficial effects of this application are:

[0017] 1. This type of pipe thread guide alignment device, when the adjusting rod is rotated, pushes the adjusting block towards the pipe through the threaded engagement with the threaded hole until the anti-slip pad is tightly attached to the outer wall of the pipe. At this time, the warning plate moves towards the guide seat under the drive of the adjusting rod's thread, compresses the warning spring and attaches to the outer wall of the guide seat, and the warning color layer is completely covered, completing the clamping and positioning of the pipe. If the adjusting rod becomes loose, the warning spring pushes the warning plate outward, exposing the warning color layer, which promptly reminds the operator to tighten the adjusting rod to prevent alignment failure, greatly improving the practicality of the device;

[0018] 2. This type of pipe thread guide alignment device allows the heat generated by friction between the pipe and the guide sleeve to be quickly dissipated to the outside through the heat dissipation groove, preventing the guide sleeve from aging due to high temperature. After connection, the adjusting rod is rotated in the opposite direction to loosen the adjusting block. The limit spring resets and drives the limit block to detach from the outer wall of the pipe. The warning plate resets under the action of the warning spring, and the guide alignment device can be removed from the pipe. The weight reduction hole design makes the tool easier to carry, effectively reducing the overall weight of the tool, improving the convenience of carrying and operation, and greatly enhancing the practicality of the device.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0024] Reference Figure 1-3A pipe thread guide alignment device includes a guide seat 1, an adjustment component, a positioning component, a guide auxiliary component, a limiting component, an anti-loosening warning component, and a weight reduction and heat dissipation structure. The guide seat 1 is a hollow cylindrical structure. The two ends of the guide seat 1 are respectively provided with positioning ports 2 for fitting the pipe to be connected. The axis of the positioning port 2 coincides with the central axis of the guide seat 1.

[0025] The adjustment components are symmetrically arranged on the outer side wall of the guide seat 1. The adjustment components include an adjustment rod 3 and an adjustment block 4. A threaded hole 5 adapted to the adjustment rod 3 is opened on the side wall of the guide seat 1. The adjustment rod 3 passes through the threaded hole 5 and extends into the interior of the guide seat 1. One end of the adjustment rod 3 located inside the guide seat 1 is rotatably connected to the adjustment block 4.

[0026] The anti-loosening warning component is set at the connection between the adjusting rod 3 and the guide seat 1. The anti-loosening warning component includes a warning spring 16, a warning plate 17 and a warning color layer 18. The warning spring 16 is sleeved on the rod body of the adjusting rod 3 outside the guide seat 1. One end of the warning spring 16 abuts against the outer wall of the guide seat 1, and the other end is fixedly connected to the warning plate 17. The warning plate 17 is sleeved on the adjusting rod 3 and threadedly connected to the adjusting rod 3. The warning color layer 18 is coated on the side end face of the warning plate 17 facing the guide seat 1.

[0027] The weight reduction and heat dissipation structure includes weight reduction holes 19 opened on the side wall of the guide seat 1 and heat dissipation grooves 20 provided on the inner wall of the guide sleeve 10. The weight reduction holes 19 are evenly distributed along the circumference of the guide seat 1, and the heat dissipation grooves 20 are opened along the axial direction of the guide sleeve 10 and communicate with the outside.

[0028] The adjusting block 4 has an arc-shaped structure, and an anti-slip pad 6 is provided on the arc-shaped inner sidewall of the adjusting block 4. The adjusting block 4 adopts an arc-shaped structure design, and its arc-shaped inner sidewall conforms to the outline of the outer wall of the pipe to be connected. The anti-slip pad 6 added to the inner sidewall can increase the friction coefficient with the outer wall of the pipe. The arc-shaped structure adapts to the outer diameter of the pipe to achieve uniform clamping. The anti-slip pad 6 improves the clamping stability and avoids damage to the outer wall of the pipe.

[0029] The positioning assembly includes a positioning ring 7 and a positioning bolt 8. The positioning ring 7 is sleeved on the outer sides of both ends of the guide seat 1. The positioning ring 7 has a positioning hole 9 on its side wall. The positioning bolt 8 passes through the positioning hole 9 and abuts against the outer side wall of the guide seat 1. The positioning ring 7 of the positioning assembly is sleeved on the outer sides of both ends of the guide seat 1. The positioning hole 9 on the side wall of the positioning ring 7 allows the positioning bolt 8 to pass through. After the positioning bolt 8 abuts against the outer side wall of the guide seat 1, the position of the positioning ring 7 is fixed by the threaded locking force. The spacing of the positioning ring 7 can be adjusted by adjusting the tightness of the positioning bolt 8 to ensure the accuracy of the pipeline connection.

[0030] A guide sleeve 10 is provided on the inner wall of the positioning ring 7. The guide sleeve 10 is coaxially arranged with the positioning port 2, and the inner diameter of the guide sleeve 10 is adapted to the outer diameter of the pipe to be connected. The guide sleeve 10 on the inner wall of the positioning ring 7 is coaxial with the positioning port 2, and its inner diameter is adapted to the outer diameter of the pipe to be connected. When the pipe is inserted, the inner wall of the guide sleeve 10 provides radial guidance, restricts pipe offset, ensures that the pipe is smoothly inserted into the connection position along the axis, and improves the smoothness of the connection.

[0031] The guiding auxiliary component includes a fixed base 11 and a guide ball 12. The fixed base 11 is fixedly connected to the inner wall of the guide base 1, and the guide ball 12 is rotatably mounted on the fixed base 11. The outer wall of the guide ball 12 contacts the threaded end face of the pipe to be connected. The fixed base 11 of the guiding auxiliary component is fixed to the inner wall of the guide base 1, and the guide ball 12 is rotatably mounted on the fixed base 11 and contacts the threaded end face of the pipe. When the pipe is pushed forward, the guide ball 12 rolls to convert sliding friction into rolling friction, reducing resistance and guiding through spherical contact to limit and guide, avoiding collision of the threaded end.

[0032] The limiting assembly includes a limiting spring 13 and a limiting block 14. An installation groove 15 is provided on the inner side wall of the guide seat 1. One end of the limiting spring 13 is fixedly connected to the bottom of the installation groove 15, and the other end of the limiting spring 13 is fixedly connected to the limiting block 14. The limiting block 14 has an arc-shaped structure and is adapted to the outer wall of the pipe to be connected. One end of the limiting spring 13 of the limiting assembly is fixed to the bottom of the installation groove 15 on the inner side wall of the guide seat 1, and the other end is connected to the arc-shaped limiting block 14 (adapted to the outer wall of the pipe). When the pipe is inserted, the elastic force of the limiting spring 13 makes the limiting block 14 fit against the outer wall of the pipe, elastically clamping and restricting axial movement, and adapting to a certain outer diameter error.

[0033] Working principle: When making threaded pipe connections, firstly, select a suitable guide sleeve 10 according to the diameter of the pipe to be connected, and fix the guide sleeve 10 inside the positioning ring 7. Then, place the positioning ring 7 on both ends of the guide seat 1. After moving the positioning ring 7 to the appropriate position, tighten the positioning bolt 8 to fix the positioning ring 7. Next, insert the two pipes to be connected into the positioning ports 2 at both ends of the guide seat 1. During the insertion process, the outer wall of the pipe presses against the limiting block 14, and the limiting block 14 compresses the limiting spring 13 and adaptively conforms to the outer wall of the pipe, realizing the initial elastic limitation of the pipe. At the same time, the threaded end face of the pipe contacts the guide ball 12 inside the guide seat 1. Under the auxiliary guiding action of the guide ball 12, the pipe axis quickly approaches the central axis of the guide seat 1. Then, the adjusting rod 3 is rotated. The adjusting rod 3 pushes the adjusting block 4 towards the pipeline through the threaded engagement with the threaded hole 5 until the anti-slip pad 6 is tightly attached to the outer wall of the pipeline. At this time, the warning plate 17 moves towards the guide seat 1 under the thread drive of the adjusting rod 3, compresses the warning spring 16 and attaches to the outer wall of the guide seat 1, and the warning color layer 18 is completely covered, completing the clamping and positioning of the pipeline. The central axes of the two pipelines are precisely aligned under the synergistic action of the guide seat 1, the guide sleeve 10 and the guide ball 12.

[0034] During the threaded connection process, the guide ball 12 rotates synchronously with the axial movement of the pipe, reducing the frictional resistance of the pipe end face; the limiting block 14, under the action of the limiting spring 13, always fits against the outer wall of the pipe, forming a double positioning with the adjustment component, effectively preventing pipe axis deviation; the heat generated by the friction between the pipe and the guide sleeve 10 is quickly dissipated to the outside through the heat dissipation groove 20, avoiding high-temperature aging of the guide sleeve 10; if the adjusting rod 3 becomes loose, the warning spring 16 pushes the warning plate 17 outward, exposing the warning color layer 18, promptly reminding the operator to tighten the adjusting rod 3 to prevent alignment failure. After the connection is completed, the adjusting rod 3 is rotated in the opposite direction to loosen the adjusting block 4, the limiting spring 13 resets and drives the limiting block 14 to disengage from the outer wall of the pipe, and the warning plate 17 resets under the action of the warning spring 16, allowing the guide alignment device to be removed from the pipe. The design of the weight reduction hole 19 makes the tool easier to carry.

[0035] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and the inventive concept of this application, should be included within the scope of protection of this application.
