Description

Technical Field

[0001] This utility model relates to the field of tee fittings technology, specifically to an adjustable-angle tee fitting. Background Technology

[0002] Most mainstream tee fittings on the market today are of fixed angle structure, meaning the angle between the branch pipe and the main pipe is determined during the manufacturing stage, with common specifications being standard angles such as 90°, 45°, or 60°. While these fixed-angle tee fittings were originally designed to adapt to standardized pipeline construction scenarios, their limitations have gradually become apparent in practical applications due to factors such as installation environment, pipeline layout adjustments, and system upgrades.

[0003] There is an adjustable-angle tee fitting in the prior art. For example, Chinese patent application with publication number CN207701998U discloses a tee fitting with a filtering function, which includes a vertical pipe and a horizontal pipe, with one end of the horizontal pipe connected to the vertical pipe. A connecting pipe is provided between the vertical pipe and the horizontal pipe, and the connecting pipe is a corrugated pipe or a metal flexible hose.

[0004] However, in practical applications, the walls of corrugated pipes and metal hoses are generally thinner, and corrugated pipes have a periodic corrugated structure while metal hoses contain gaps in the braided layers. The overall structural rigidity is much lower than that of rigid pipe fittings. In high-pressure fluid scenarios (such as industrial hydraulics and high-pressure water supply and drainage), the pipe walls are prone to bulging and deformation due to the inability to withstand the pressure, and in severe cases, they may even rupture directly, thus posing certain limitations. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable-angle tee fitting. Through the three-section structure of "spherical joint - rigid pipe - corrugated pipe", it achieves a smooth connection between rigidity and flexibility, and solves the problem of bulging and cracking when a single corrugated pipe bears the load alone.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable angle tee fitting, comprising a device body, wherein the device body includes a tee body, and an adjustment base is provided at one end of the tee body;

[0007] The adjusting base is equipped with an adjusting mechanism for adjusting the angle of one end of the tee body;

[0008] The adjustment mechanism includes a spherical joint, which precisely matches the hemispherical groove of the adjustment base. One end of the spherical joint is fixedly connected to a rigid tube, one end of the rigid tube is fixedly connected to a corrugated tube, and one end of the corrugated tube is welded to a metal connecting tube.

[0009] The top of the metal connecting pipe is provided with a fixing mechanism for fixing the angle of the corrugated pipe.

[0010] Preferably, one end of the adjusting base is fixedly connected to a limiting part, and a sealing rubber ring is fixedly connected to the bottom of the limiting part.

[0011] Preferably, a first sealing tape is fixedly fitted onto the surface of the connection point between the spherical joint and the rigid pipe to seal the gap between the spherical joint and the rigid pipe.

[0012] Preferably, a second sealing tape is fixedly fitted onto the surface of the connection point between the rigid pipe and the corrugated pipe to seal the gap between the rigid pipe and the corrugated pipe.

[0013] Preferably, a first fixing block is fixedly connected to the top of the metal connecting pipe, a second fixing block is fixedly connected to the top of the ball joint, and a third fixing block is fixedly connected to the top of the rigid pipe.

[0014] Preferably, the fixing mechanism includes a first connecting rod and a second connecting rod, the first connecting rod being hinged to a first fixing block, the second connecting rod being hinged to a second fixing block, and one end of the first connecting rod and the second connecting rod being located on both sides of a third fixing block, respectively.

[0015] Preferably, the first connecting rod is connected to the third fixing block by a first tightening bolt, and the second connecting rod is connected to the third fixing block by a second tightening bolt.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model provides an adjustable angle tee fitting. Through a three-section structure of "spherical joint - rigid pipe - corrugated pipe", it achieves a smooth connection between rigidity and flexibility, avoiding stress concentration. The spherical joint, as the core adjustment component, is responsible for achieving a wide range of lockable angle adjustment. At the same time, it bears the main pressure and rigid support of the pipeline system, preventing the corrugated pipe from bearing high pressure or heavy load. This solves the problem of a single corrugated pipe bulging and breaking when bearing load alone.

[0018] 2. This utility model discloses an adjustable angle tee fitting. By setting a first connecting rod and a second connecting rod, and configuring two sets of independent tightening bolts to limit and fix both, it realizes the independent adjustment function of the ball joint and the bellows. This design not only ensures that the ball joint and the bellows can obtain a stable and reliable fixing effect after adjustment, but also effectively avoids mutual interference between the two during individual adjustment, thereby significantly improving the accuracy and convenience of adjustment operation.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The adjustable angle tee fitting shown includes a device body 1, which includes a tee body 11, and an adjustment base 12 is provided at one end of the tee body 11.

[0029] The adjustment base 12 is equipped with an adjustment mechanism 3, which is used to adjust the angle of one end of the tee body 11.

[0030] To facilitate adjustment of the angle at one end of the tee body 11, such as... Figure 5As shown, the adjustment mechanism 3 includes a ball joint 31, which precisely matches the hemispherical groove of the adjustment base 12, enabling 360° horizontal rotation + ±30° vertical flipping. One end of the ball joint 31 is fixedly connected to a rigid pipe 33, and one end of the rigid pipe 33 is fixedly connected to a corrugated pipe 34. One end of the corrugated pipe 34 is welded to a metal connecting pipe 35, and the inside of the metal connecting pipe 35 is connected to a water pipe.

[0031] It should be noted that the top of the metal connecting pipe 35 is fixedly connected to the first fixing block 36, the top of the ball joint 31 is fixedly connected to the second fixing block 37, and the top of the rigid pipe 33 is fixedly connected to the third fixing block 38.

[0032] It is worth noting that this utility model is mainly adjusted through the ball joint 31, while the bellows 34, as an auxiliary compensation component, only undertakes the correction of minor angle deviations or vibration buffering, to offset minor misalignments during installation, or to absorb the impact of fluid pressure fluctuations and equipment vibrations on the pipe fittings, and does not participate in the main angle adjustment.

[0033] To secure the adjusted spherical joint 31 and bellows 34, such as Figure 5 As shown, a fixing mechanism 2 is provided at the top of the metal connecting pipe 35 to fix the angle of the corrugated pipe 34.

[0034] The fixing mechanism 2 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is hinged to the first fixing block 36, and the second connecting rod 22 is hinged to the second fixing block 37. One end of the first connecting rod 21 and the second connecting rod 22 are located on both sides of the third fixing block 38, respectively.

[0035] The first connecting rod 21 is connected to the third fixing block 38 by the first tightening bolt 23, and the second connecting rod 22 is connected to the third fixing block 38 by the second tightening bolt 24.

[0036] It is worth noting that when the ball joint 31 is adjusted, the bellows 34 can be kept in a fixed state by its corresponding second tightening bolt 24; conversely, when the bellows 34 is adjusted, the ball joint 31 can also be locked in position by its own first tightening bolt 23.

[0037] It is worth noting that the first connecting rod 21 and the first fixing block 36, and the second connecting rod 22 and the second fixing block 37 are respectively connected one-to-one by a damping shaft (the damping shaft can assist in the temporary positioning of the connecting rods to prevent them from shaking randomly during adjustment). After the angle adjustment of the ball joint 31 and the bellows 34 is completed, the first connecting rod 21 and the second connecting rod 22 need to be operated—aligning the mounting holes at the ends of the two rods furthest from the corresponding fixing blocks with the two sets of openings on the top of the third fixing block 38; if there is a misalignment between the mounting holes and the openings, the connecting rods can be slightly rotated by the damping shaft to make the mounting holes and openings precisely aligned. Then, the first tightening bolt 23 and the second tightening bolt 24 are inserted into the mounting holes of the corresponding connecting rods and then through the openings of the third fixing block 38 in sequence. Finally, the bolts are tightened to achieve a stable connection between the first connecting rod 21, the second connecting rod 22 and the third fixing block 38, thereby locking the adjustment angle of the ball joint 31 and the bellows 34.

[0038] In order to seal the surface of the adjusting base 12, a limiting part 13 is fixedly connected to one end of the adjusting base 12. A sealing rubber ring 14 is fixedly connected to the bottom of the limiting part 13. Because the sealing rubber ring 14 has a certain elasticity, during the downward rotation of the ball joint 31, the ball joint 31 will compress the bottom sealing rubber ring 14, causing the sealing rubber ring 14 to contract. At the same time, the top sealing rubber ring 14 will rebound, so that the sealing rubber ring 14 contacts the top of the ball joint 31, thereby achieving the sealing of the adjusting base 12.

[0039] To prevent leakage at the connection point between the ball joint 31 and the rigid pipe 33, a first sealing tape 32 is fixedly fitted onto the surface of the connection point between the ball joint 31 and the rigid pipe 33 to seal the gap between the ball joint 31 and the rigid pipe 33.

[0040] To prevent leakage at the connection point between the rigid pipe 33 and the bellows 34, a second sealing tape 39 is fixedly fitted onto the surface of the connection point between the rigid pipe 33 and the bellows 34 to seal the gap between them.

[0041] It is worth noting that both the first sealing tape 32 and the second sealing tape 39 are mainly made of synthetic rubber or polymer.
