Description

Technical Field

[0001] The present invention relates to the technical field of pipe connectors, and specifically to a pipe connector for stainless steel clean materials. Background Art

[0002] Stainless steel water supply pipes are "green pipes of the 21st century", with characteristics such as pollution-free, high strength, long life, small fluid resistance, low comprehensive cost, and good appearance. They are ideal substitutes for other types of pipes and will also be the ultimate choice for water supply pipes.

[0003] In this regard, Chinese Patent Application No.: CN201910518622.6 discloses a pipe connector for condensate water supply pipes in a thermal power plant, including a pipe body. The upper and lower sides of the left side of the pipe body are both connected through a first connection block, and a vertical plate is movably connected to the middle lower part of the right side of the first connection block. First springs are fixedly connected to the front and rear sides of the vertical plate, and first sliders are fixedly connected to the outer ends of the first springs. A first reinforcement block is arranged below the first slider. A second connection block is arranged on the left side of the first connection block, and a connector body is arranged on the right side of the second connection block. Second sliders are movably connected to the upper and lower sides of the front surface of the connector body. A second reinforcement block is fixedly connected to the outer end of the connecting rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The stainless steel clean material pipeline connector is provided with a first pipeline, a second pipeline, a first connecting ring, a second connecting ring, a clamping groove, a movable groove, a fastening groove, a stabilizing seat, a bearing body, a rotating shaft, a first gear, a second gear, a limiting rod, a movable ring, a locking hook and a fixed half ring. When in use, the first pipeline and the second pipeline are first aligned. After alignment, the rotating shaft and the first gear enter the inside of the clamping groove and the movable groove. Then, the second pipeline is rotated clockwise as a whole so that the rotating shaft rotates inside the movable groove, so that the rotating shaft is abutted and fastened at the position of the fastening groove, and the first gear is driven to move by the rotating shaft. After the displacement is completed, the first gear is aligned with the second gear. When the rotating shaft is in contact with the rotating shaft, the locking hook is parallel to the rotating shaft. Manually rotating the rotating shaft clockwise can drive the movable ring to start rotating counterclockwise, so that the movable ring will drive the locking hook to rotate slowly counterclockwise. When the locking hook hits the surface of the rotating shaft, the rotating shaft stops rotating. The rotating shaft is provided with four groups, and the rotating shaft is fixed and locked by four groups of locking hooks to ensure the stability of the first connecting ring and the second connecting ring after connection, and ensure the connection effect of the first pipe and the second pipe to the outside. At the same time, when it is necessary to disassemble it later, the rotating shaft can be directly rotated counterclockwise, and the locking hook will be released immediately, so that the first pipe and the second pipe can be inspected, which reflects the functionality of the design.

[0018] 2. When using this stainless steel clean material pipeline connector, through the set fixed half-groove, fixed ring, installation half-ring, connecting rod, installation plate, compression spring, telescopic rod, bottom plate, contact frame, first movable shaft body, second movable shaft body, first movable shaft frame, first moving plate and first stabilizing shaft, when starting to rotate the second pipeline, at this time the installation half-ring and the fixed half-ring are in the same position. Immediately after rotating the second pipeline, the installation half-ring will also rotate. The installation half-ring will enter the inside of the fixed half-groove and coincide with the fixed half-ring. And before the rotation ends, the connecting rod will contact the contact frame. At this time, the installation half-ring is still rotating, so the compression spring begins to contract upward. The displacement direction of the compression spring is positioned by two groups of telescopic rods. At this time, the whole bottom plate moves upward, and the second movable shaft frame and the first movable shaft frame begin to move upward, so as to drive the first moving plate and the second moving plate to move inward. At the same time, when the first moving plate and the second moving plate move inward, they can drive the first clamping half-ring and the second clamping half-ring to clamp inward. Thus, after the rotation of the installation half-ring ends, the first clamping half-ring and the second clamping half-ring will stably clamp the connecting rod. Through the design of the anti-slip pad, the friction between the first clamping half-ring, the second clamping half-ring and the connecting rod can also be strengthened, ensuring the stable effect inside the first pipeline and the second pipeline, solving the problem of the previous separate stability inside and outside. The operation is relatively simple when using, and it can be self-locked for a long time, reflecting the ingenuity of the design. BRIEF DESCRIPTION OF THE DRAWINGS

A compression spring 22 and a telescopic rod 23 are arranged at the bottom end of the mounting plate 21 in sequence from left to right. One end of the compression spring 22 away from the mounting plate 21 is fixedly connected to a bottom plate 24. A resisting frame 25 is fixedly connected to the bottom end of the bottom plate 24. A second movable shaft body 27 is arranged on the right side surface of the bottom plate 24. A second movable shaft frame 34 is arranged on the surface of the second movable shaft body 27. A second moving plate 35 is arranged on the surface of the second movable shaft frame 34. A fourth movable shaft 38 is arranged on the left side surface of the second moving plate 35. A second clamping half-ring 39 is arranged on the surface of the fourth movable shaft 38. An anti-slip pad 40 is arranged on the surface of the second clamping half-ring 39. A second stabilizing shaft 36 is fixedly connected to the top end of the second moving plate 35. A second limiting plate 37 is arranged on the back surface of the second stabilizing shaft 36. The second limiting plate 37 is installed on the right end surface of the fixed half-ring 16. A first movable shaft body 26 is arranged on the left side surface of the bottom plate 24. A first movable shaft frame 28 is arranged on the surface of the first movable shaft body 26. A first moving plate 29 is arranged on the surface of the first movable shaft frame 28. A third movable shaft 32 is arranged on the back surface of the first moving plate 29. A first clamping half-ring 33 is arranged on the surface of the third movable shaft 32. The height of the first clamping half-ring 33 is lower than that of the resisting frame 25. A first stabilizing shaft 30 is arranged at the top end of the first moving plate 29. A first limiting plate 31 is fixedly connected to the back surface of the first stabilizing shaft 30. The first limiting plate 31 is installed on the right side surface of the fixed half-ring 16. There are two groups of telescopic rods 23, and both groups of telescopic rods 23 are installed on the left and right sides of the compression spring 22. A fixed half-slot 17 is formed on the right side surface of the fixed half-ring 16. A fixed ring 18 is fixedly connected to the inner side wall of the second pipe 2. A connecting rod 20 is fixedly connected to the left side surface of the fixed ring 18. One end of the connecting rod 20 away from the fixed ring 18 is provided with a mounting half-ring 19. The mounting half-ring 19 is adapted to the fixed half-slot 17. Align the first pipe 1 and the second pipe 2. Then, after alignment, the rotating shaft 10 and the first gear 11 will enter the inside of the clamping slot 5 and the movable slot 6. Then, rotate the second pipe 2 as a whole clockwise, so that the rotating shaft 10 will rotate inside the movable slot 6. Thus, the rotating shaft 10 will abut and fasten at the position of the fastening slot 7. Drive the first gear 11 to displace through the rotating shaft 10. After the displacement ends,The first gear 11 will contact the second gear 12. At this time, the locking hook 15 is parallel to the rotating shaft 10. The rotating shaft 10 is manually rotated clockwise to drive the movable ring 14 to start counterclockwise rotation, so that the movable ring 14 will drive the locking hook 15 to slowly rotate counterclockwise. When the locking hook 15 hits the surface of the rotating shaft 10, the rotating shaft 10 stops rotating. The rotating shaft 10 is provided with four groups. The rotating shaft 10 is locked by the four groups of locking hooks 15 to ensure that the first connecting ring 3 and the second connecting ring 4 are connected. The stability of the first pipe 1 and the second pipe 2 is ensured, and the connection effect of the first pipe 1 and the second pipe 2 to the outside is ensured. At the same time, when it is necessary to disassemble them later, the rotating shaft 10 can be directly rotated counterclockwise, and the locking hook 15 will be immediately loosened, so that the first pipe 1 and the second pipe 2 can be checked. When the second pipe 2 starts to be rotated, the installation semi-ring 19 and the fixed semi-ring 16 are in the same position. Then, after the second pipe 2 is rotated, the installation semi-ring 19 will also rotate, and the installation semi-ring 19 will enter the interior of the fixed semi-groove 17 and overlap with the fixed semi-ring 16. Before the rotation is completed, the connecting rod 20 will contact the contact frame 25. At this time, the installation semi-ring 19 is still rotating, so that the extrusion spring 22 begins to shrink upward, and the displacement direction of the extrusion spring 22 is positioned by two sets of telescopic rods 23. At this time, the bottom plate 24 moves upward as a whole, and the second movable axis frame 34 and the first movable axis frame 28 start to move upward, thereby driving the first moving plate 29 and the second moving plate 35 to move inward. At the same time, when the first moving plate 29 and the second moving plate 35 move inward, they can drive the first The clamping half ring 33 and the second clamping half ring 39 clamp inwardly, so that when the installation half ring 19 is rotated, the first clamping half ring 33 and the second clamping half ring 39 will stably clamp the connecting rod 20. The design of the anti-slip pad 40 can also strengthen the friction between the first clamping half ring 33, the second clamping half ring 39 and the connecting rod 20, ensuring the stability of the first pipe 1 and the second pipe 2, solving the problem of separate stability of the inside and outside in the past. The operation is relatively simple during use, and it can be self-locking for a long time.

[0033] Working principle: When in use, align the first pipe 1 and the second pipe 2. After alignment, the rotating shaft 10 and the first gear 11 will enter the inside of the clamping groove 5 and the movable groove 6. Then, rotate the second pipe 2 as a whole clockwise, so that the rotating shaft 10 will rotate inside the movable groove 6. Thus, the rotating shaft 10 will abut and fasten at the position of the fastening groove 7. Drive the first gear 11 to displace through the rotating shaft 10. After the displacement ends, the first gear 11 will contact with the second gear 12. At this time, the locking hook 15 is in a state parallel to the rotating shaft 10. Manually rotate the rotating shaft 10 clockwise, which can drive the movable ring 14 to start rotating counterclockwise. Thus, the movable ring 14 will drive the locking hook 15 to slowly rotate counterclockwise. When the locking hook 15 abuts against the surface of the rotating shaft 10, stop rotating the rotating shaft 10. And there are four groups of rotating shafts 10. The rotating shaft 10 is clamped and locked by four groups of locking hooks 15 to ensure the stability after the first connecting ring 3 and the second connecting ring 4 are connected, and ensure the connection effect between the first pipe 1 and the second pipe 2 outside. At the same time, when it needs to be disassembled later, it can be directly rotated counterclockwise to rotate the rotating shaft 10. The locking hook 15 will immediately loosen, so as to inspect the first pipe 1 and the second pipe 2. When starting to rotate the second pipe 2, at this time, the installation half-ring 19 and the fixed half-ring 16 are in the same position. Then, after rotating the second pipe 2, the installation half-ring 19 will also rotate. The installation half-ring 19 will enter the inside of the fixed half-groove 17 and coincide with the fixed half-ring 16. And before the rotation ends, the connecting rod 20 will abut against the abutting frame 25. At this time, the installation half-ring 19 is still rotating, so as to squeeze the spring 22 to start shrinking upward. The displacement direction of the compression spring 22 is positioned by two groups of telescopic rods 23. At this time, the bottom plate 24 as a whole moves upward, and the second movable shaft frame 34 and the first movable shaft frame 28 start to move upward, so as to drive the first moving plate 29 and the second moving plate 35 to displace inward. At the same time, when the first moving plate 29 and the second moving plate 35 displace inward, they can drive the first clamping half-ring 33 and the second clamping half-ring 39 to clamp inward. Thus, after the installation half-ring 19 finishes rotating, the first clamping half-ring 33 and the second clamping half-ring 39 will stably clamp the connecting rod 20. Through the design of the anti-slip pad 40, the friction between the first clamping half-ring 33, the second clamping half-ring 39 and the connecting rod 20 can also be strengthened, ensuring the stable effect inside the first pipe 1 and the second pipe 2, and solving the problem of the previous separate stability inside and outside. The operation is relatively simple when in use, and it can be self-locked for a long time. The above is all the working principles of the present invention.

[0034] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.
