Description

Technical Field

[0001] The utility model relates to the technical field of reducing pipe fittings, in particular to a steering reducing pipe fitting. Background Art

[0002] Reducing pipe fittings consist of two flanges of different diameters and a hollow pipe. Reducing pipe fittings are commonly used in oil and gas pipelines, chemical pipelines, sewage treatment pipelines and other fields. The function of reducing pipe fittings is to connect pipes of different diameters to achieve pipeline connectivity and fluid transmission. Compared with pipes of the same diameter, reducing pipes can reduce the pressure loss of the fluid and the sharp change in flow rate, which is conducive to the stable flow of the fluid. In addition, reducing pipe fittings also have the advantages of convenient connection, simple installation, and reliable performance. They are widely used in various engineering fields. In the construction and decoration of some buildings, it is often necessary to use steering reducing pipe fittings: tee joints. Tee joints can change the direction of the fluid and are very convenient to use. The tee pipe fittings open a vertical pipe body structure on the middle side of the straight pipe fittings to form a T-shaped tee with three openings for circulation.

[0003] The existing Chinese patent with announcement number CN219692577U discloses a three-way joint, including a straight-through pipe body and an annular pipe arranged on one side of the straight-through pipe body, the straight-through pipe body is connected to the annular pipe through a bellows, a mounting block is fixedly connected to the annular pipe, a sliding rod is slidably connected to the mounting block, a sliding block is arranged at one end of the sliding rod, the sliding block is slidably connected to the straight-through pipe body, a fixed block is fixedly connected to the annular pipe, a fixing mechanism is arranged on the fixed block, the fixing mechanism includes a limit rod slidably connected to the fixed block, the limit rod is tightly connected to the fixed block through a first spring, an arc plate is fixedly connected to the straight-through pipe body, and a limit block used in conjunction with the arc plate is hinged on the limit rod.

[0004] Although the above scheme has a simple structure and is easy to install and connect, the vertical pipe body structure of the three-way joint is fixed, and the position of the vertical pipe body opening cannot be steered and adjusted according to different needs, resulting in large limitations on the use of the pipe fitting and inflexible use. Therefore, it does not meet existing needs. In this regard, we propose a steering type reducer pipe fitting. Utility Model Content

[0005] The utility model aims to provide a steering type reducing pipe fitting to solve the problem that the reducing pipe fitting proposed in the above background technology cannot perform steering adjustment on the position of the vertical pipe body opening according to different requirements, resulting in inflexible use.

[0010] Preferably, an annular limiting groove is formed on the outer wall of one end of the first rotating shaft located outside the steering box, and the annular limiting groove is matched with the annular limiting groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides a steering box at the upper end of the different-diameter pipe body. When the steering nozzle needs to be rotationally adjusted, the user can turn the knob, and the knob will drive the first rotating shaft to rotate the transmission worm. Due to the worm transmission between the transmission worm and the transmission worm wheel, the second rotating shaft will drive the steering nozzle to rotate through the transmission worm wheel, thereby realizing the rotation adjustment of the steering nozzle, meeting different installation requirements, and improving practicality. In addition, since the worm transmission has self-locking properties, it is difficult for the transmission worm wheel and the steering nozzle to rotate independently except through the rotation of the transmission worm, so the stability of the steering nozzle after the steering adjustment is guaranteed, and the overall adjustment is convenient and fast, and easy to use.

[0017] 2. The utility model provides a limit box on one side of the front end of the steering box. When the steering nozzle is adjusted, the lifting plate can be lifted upward, and the lifting plate will drive the connecting block to make the arc clamping block away from the annular limit groove, so that the first rotating shaft can be easily rotated. When the steering nozzle is adjusted, the lifting plate can be released, and under the influence of the reset spring, the lifting plate can be made to drive the arc clamping block to squeeze and fit the annular limit groove, so that the first rotating shaft can be avoided from rotating randomly through squeezing and fitting, thereby ensuring the stability of the transmission worm and avoiding the rotation of the transmission worm wheel.

[0018] 3. The utility model provides a protection box on the outside of the limit box, and the protection box is connected to the steering box through a damping shaft. When the steering nozzle is adjusted, the protection box can be turned upward to open, and when the steering adjustment is completed, the protection box can be turned downward. The lower end of the protection box can be magnetically adsorbed by a magnetic iron sheet, so that the protection box can shield and protect the knob, which can prevent the knob from being rotated due to accidental operation and accidental touch, thereby improving the protection.
