Description

Technical Field

[0001] This utility model relates to the field of hardware and instrument technology, and in particular to a ferrule-type through-plate welding pipe joint. Background Technology

[0002] In various industrial pipeline systems, reliable pipe fittings are crucial for ensuring stable fluid transmission and maintaining normal system operation. Compression fittings mainly consist of a fitting body, a compression fitting, a nut, and a welding assembly for fixing.

[0003] Existing socket weld pipe fittings also utilize a compression fitting structure for connection, which is convenient. However, compression fitting socket weld pipe fittings are not suitable for use in locations subject to vibration, as they can easily cause the nut to rotate and loosen the connection.

[0004] An existing patent (publication number: CN218063768U) discloses a ferrule-type socket welding pipe joint. By inserting the pipe into the threaded groove and rotating the nut, the ferrule is used to clamp the pipe into the pipe joint. At this time, pulling the pull plate will push the limit rod into the limit hole by the spring, which can limit the rotation direction of the curtain and prevent vibration from causing the nut to rotate and the pipe connection to loosen.

[0005] Existing patents offer solutions to the aforementioned problems, but their installation efficiency is poor. In actual use, due to the lack of splicing structures, they cannot meet the needs of efficient operation in scenarios where rapid pipe splicing is required. Operators need to spend a lot of time and energy using other auxiliary tools or methods to splice the pipes, which delays the project schedule and reduces the practicality of the device.

[0006] To address this, a compression fitting-type through-plate welding pipe joint is proposed. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-5The present invention provides the following technical solution:

[0029] A compression fitting for welding pipe joints includes a main pipe 1, a secondary pipe 2 on the right side of the main pipe 1, and a snap-fit ​​assembly 3 fixedly connected between the secondary pipe 2 and the surface of the main pipe 1. A connecting assembly 4 is fixedly connected to the right side inside the main pipe 1, and the other end of the connecting assembly 4 extends into the interior of the secondary pipe 2. The connecting assembly 4 includes a connecting pipe 401, and fixing blocks 402 are fixedly connected to the right sides of the front and rear sides of the connecting pipe 401. The surface of the connecting pipe 401 contacts the inner wall of the secondary pipe 2. Movable plates 403 are movably connected inside the two fixing blocks 402, and springs 404 are fixedly connected to the opposite sides of the two movable plates 403. A pressing block 405 is fixedly connected to the side of the movable plate 403 away from the springs 404, and the other end of the pressing block 405 extends to the outside of the fixing blocks 402.

[0030] In this embodiment: by pressing the pressing block 405, the moving plate 403 moves smoothly inside the fixed block 402 and compresses the spring 404, which can release the lock of the connecting component 4, making it easier to connect the main pipe 1 and the secondary pipe 2. When the connection is completed, the spring 404 rebounds and drives the pressing block 405 to return smoothly to its original position under the constraint of the moving hole 9, so that the pressing block 405 is embedded in the secondary pipe 2 to complete the connection, which facilitates the maintenance and replacement of the pipeline, ensures the normal use of the subsequent pipeline system, and improves the ease of use of the connecting component 4. Then, through the cooperation of the positioning plate 302 and the buckle block 303, the annular buckle 304 drives the secondary pipe 2 to move smoothly under the constraint of the positioning plate 302. When it moves into place, the buckle block 303 is rotated to complete the initial locking, and the annular buckle 304 is embedded in the rotating ring 305 to form a lock. The rotating ring 305 is then rotated to complete the secondary fixing, which simplifies the installation of the main pipe 1 and the secondary pipe 2, eliminates the problem of misalignment, and improves the ease of use of the buckle component 3.

[0031] Specifically, such as Figure 5 As shown, the buckle assembly 3 includes a connecting ring 301. Positioning plates 302 are fixedly connected to the top and bottom of the right side of the connecting ring 301. A buckle block 303 is rotatably connected to the other end of the positioning plate 302. The connecting ring 301 is fixedly connected to the right side of the surface of the main pipe 1. An annular buckle 304 is slidably connected to the surface of the positioning plate 302. The annular buckle 304 is fixedly connected to the left side of the surface of the secondary pipe 2. A rotating ring 305 is rotatably connected to the surface of the connecting ring 301. The rotating ring 305 engages with the annular buckle 304.

[0032] Specifically, such as Figure 4 As shown, a slot 5 is provided on the right side of the rotating ring 305 to cooperate with the annular buckle 304, and the surface of the annular buckle 304 is in contact with the inner wall of the slot 5.

[0033] Specifically, such as Figure 4 As shown, a rotating groove 6 is provided on the left side of the interior of the rotating ring 305 to cooperate with the connecting ring 301, and the surface of the connecting ring 301 is in contact with the inner wall of the rotating groove 6.

[0034] Specifically, such as Figure 4 As shown, the top and bottom of the annular buckle 304 are provided with connection holes 7 for use with the positioning plate 302, and the surface of the positioning plate 302 is in contact with the inner wall of the connection hole 7.

[0035] In this embodiment: the positioning plate 302 and the connecting hole 7 work together to form a guide structure, so that the annular buckle 304 drives the secondary tube 2 to move smoothly under the constraint of the positioning plate 302. When it moves to the appropriate position, the buckle block 303 is rotated to lock, realizing the connection between the connecting ring 301 and the annular buckle 304, so that the annular buckle 304 is embedded in the slot 5 of the rotating ring 305. At the same time, through the cooperation of the rotating ring 305 and the rotating groove 6, the rotating ring 305 rotates smoothly under the restriction of the rotating groove 6, and synchronously drives the slot 5 to rotate along the annular buckle 304 to form a locking engagement. The two work together to complete the double-layer locking, which not only facilitates the installation of the main tube 1 and the secondary tube 2, but also prevents the phenomenon of displacement, thus improving the convenience of using the buckle assembly 3.

[0036] Specifically, such as Figure 4 As shown, both fixed blocks 402 have a moving groove 8 inside for use with the moving plate 403, and the side of the spring 404 away from the moving plate 403 is fixedly connected to the side of the inner wall of the moving groove 8 near the connecting pipe 401.

[0037] Specifically, such as Figure 4 As shown, each of the two fixed blocks 402 has a movable hole 9 on its opposite side for use with the pressing block 405, and the movable hole 9 is connected to the movable groove 8.

[0038] In this embodiment: the moving hole 9 communicates with the moving groove 8, so that the pressing block 405 drives the moving plate 403 to move smoothly under the restriction of the moving groove 8 and compress the spring 404, thereby releasing the lock of the connecting component 4, which facilitates the splicing of the main pipe 1 and the secondary pipe 2. When the connection is completed, the spring 404 rebounds and drives the pressing block 405 to return smoothly under the constraint of the moving hole 9, so that the pressing block 405 is embedded in the secondary pipe 2 to complete the splicing, which facilitates the maintenance and replacement of the pipeline and improves the ease of use of the connecting component 4.

[0039] Specifically, such as Figure 2 , Figure 3 As shown, the front and rear sides of the left side of the inner wall of the secondary pipe 2 are provided with positioning grooves 10 for use with the fixing block 402, and the surface of the fixing block 402 is in contact with the inner wall of the positioning groove 10.

[0040] Specifically, such as Figure 2 , Figure 3 As shown, positioning holes 11 are provided on the left side of both the front and rear sides of the secondary tube 2 to cooperate with the pressing block 405, and the positioning holes 11 are connected to the positioning groove 10.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the inner walls of both the main pipe 1 and the secondary pipe 2 are coated with anti-corrosion paint.

[0042] In this embodiment: the positioning hole 11 and the positioning groove 10 work together to form a guiding structure, so that the fixing block 402 moves smoothly under the restriction of the positioning groove 10, ensuring that the main pipe 1 and the secondary pipe 2 are accurately connected. After the splicing is completed, the spring 404 rebounds and drives the pressing block 405 to accurately embed into the interior of the positioning hole 11, realizing the rapid splicing of the main pipe 1 and the secondary pipe 2. In addition, the inner walls of the main pipe 1 and the secondary pipe 2 are coated with anti-corrosion coating, which can greatly increase the service life of the pipeline and improve the practicality of the device.

[0043] Working principle: When splicing pipes, the operator first manually presses the pressing block 405, which drives the moving plate 403 to move smoothly under the restriction of the moving groove 8 and compresses the spring 404, releasing the lock of the connecting component 4. Then, the operator manually rotates the buckle block 303 to release the lock of the annular buckle 304, and simultaneously aligns the positioning plate 302 with the connecting hole 7 and pushes the secondary pipe 2 closer to the main pipe 1. During the pushing process, the fixing block 402 moves smoothly along the positioning groove 10 of the secondary pipe 2. When it moves to the appropriate position, the operator manually rotates the buckle block 303 to complete the locking. At the same time, the spring 404 rebounds and drives the pressing block 405 to embed into the positioning hole 11, realizing the initial quick splicing of the main pipe 1 and the secondary pipe 2. In addition, the annular buckle 304 is embedded in the slot 5 in the rotating ring 305. Then, the rotating ring 305 is rotated to complete the secondary fixation of the main pipe 1 and the secondary pipe 2. This simplifies the installation process of the main pipe 1 and the secondary pipe 2, and effectively prevents the splicing from shifting and loosening, ensuring the stability of the pipeline connection and ensuring the normal use of the subsequent pipeline system.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
