Description

Technical Field

[0001] This utility model belongs to the technical field of pipe connectors, and specifically relates to a slanted tee. Background Technology

[0002] Tees, also known as pipe tees, tee fittings, or tee connectors, are widely used in pipeline systems for transporting liquids. Their core function is to change the direction of fluid flow. They are usually installed at key nodes where branch pipes need to branch off from the main pipeline. As an important category of tee fittings, the oblique tee is distinguished from the ordinary tee by the fact that the branch pipe is arranged at an angle. With this structural feature, oblique tees have unique advantages in reducing fluid transport resistance and reducing local pressure loss in the pipeline network. Therefore, they are widely used in various liquid transport pipeline networks. In the construction and application of existing liquid transportation pipeline networks, the main pipelines are usually laid in accordance with standardized design specifications. The size and specifications of the main pipelines in the corresponding pipeline network system remain uniform. Based on the standardized characteristics of the main pipelines, the main pipe dimensions of the tee fittings that are compatible with them can also be designed and produced in a unified manner, without the need for differentiated research and development for the main pipe. However, the branch pipe connection scenarios of the pipeline network system show significant diversity. The setting of different branch pipes often needs to be adapted to specific transportation requirements, installation environment and interface specifications of downstream supporting equipment. This makes it difficult to unify the size and specifications of the branch pipes, which in turn makes it necessary to customize the related structures of the tee fittings that are compatible with the branch pipes. Due to the diversity of branch pipe sizes and specifications, existing technologies require separate mold development and customized production for tee fittings to meet different branch pipe needs. This customized production model not only significantly increases the manufacturing cost of tee fittings but also extends the production cycle, resulting in extremely poor versatility and interchangeability of the fittings, making it difficult to meet the flexible adaptation needs in the construction and maintenance of pipeline systems. The problems are particularly acute in applications involving temporary and short-term pipeline connections. For example, emergency repairs during sudden failures of municipal pipelines require the temporary construction of branch pipelines to bypass damaged sections and ensure normal water supply or sewage disposal for surrounding users. The construction of temporary water supply and fire-fighting water branch pipelines during building construction requires rapid connection to meet temporary fluid transport needs. In emergency rescue scenarios, such as drainage after floods or emergency transfer after hazardous liquid leaks, temporary pipelines need to be urgently constructed to achieve directional diversion or safe transport of fluids. Furthermore, scenarios such as temporary process adjustments in industrial production and short-term pipeline construction for large temporary event venues all require rapid connection of oblique tees with branch pipes of different specifications. Existing oblique tees are limited by the customized design of branch pipe adaptation structures and lack universal adaptability. As a result, in the aforementioned temporary connection scenarios, users need to carry multiple oblique tees and matching connectors with different branch pipe specifications in advance. This not only increases the cost of carrying, transportation and management, but may also cause delays in temporary connection work due to the lack of compatibility specifications, affecting the smooth progress of emergency response, construction progress or temporary support work. It is evident that the existing technology has certain defects and shortcomings, and therefore needs to be improved and designed. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an oblique tee to more accurately resolve the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes an oblique tee, including a tee main pipe, a secondary branch pipe welded to the top of the tee main pipe, and a convertible connector fixedly installed on the top of the secondary branch pipe. The convertible connector includes a fixed plate and a sleeve connector. The fixed plate is fixedly connected to the top of the secondary branch pipe. A telescopic mechanism is fixedly installed on the side of the fixed plate near the main tee pipe. A rotating mechanism is fixedly installed on the moving end of the telescopic mechanism. Installation components are arranged in a ring at equal intervals on the outer side of the rotating mechanism. A sealing plug is rotatably connected to the inner side of the installation components. The sleeve connector is fixedly connected to the end of the secondary branch pipe away from the main tee pipe. The inner end of one sealing plug is inserted into the sleeve connector. Threaded connectors of different sizes are fixedly connected to the outer sides of each sealing plug. The threaded connectors are connected through the sealing plug and the sleeve connector. The outer ends of the sleeve joint and the secondary branch pipe are connected. During use, sealing plugs with different sizes of threaded joints are installed at equal intervals on the outside of the rotating mechanism through the installation component. During use, first adjust the sealing plug at the bottom of the corresponding size threaded joint to align with the sleeve joint according to the required installation requirements. At this time, simply adjust the telescopic mechanism to retract, which will drive the sealing plug inward and cause the sealing plug to be inserted into the inside of the sleeve structure. At this time, the sealing plug, the sleeve joint and the secondary branch pipe are connected. The installation can be completed by connecting the external pipe thread to the inside of the threaded joint. At the same time, different external joints can be pre-selected and installed through the installation component during use to achieve high adaptability.

[0005] Furthermore, the telescopic mechanism includes a sleeve, which is fixedly connected to the side of the fixed plate near the main tee pipe. A lead screw is rotatably connected inside the sleeve. An adjustment component is provided at the bottom end of the sleeve. The top of the adjustment component is connected to the bottom of the lead screw. A slider is threadedly connected to the outer surface of the lead screw. The slider is slidably connected inside the sleeve. A sleeved slide tube is fixedly connected to the top of the slider. A rotating mechanism is rotatably connected to the top of the sleeved slide tube. The sleeved slide tube slides inside the sleeve. The sleeved slide tube covers the outside of the lead screw for dust protection.

[0006] Furthermore, the adjustment assembly includes an adjustment handwheel, which is rotatably connected to the bottom end of the sleeve. The top of the adjustment handwheel is connected to the bottom of the lead screw via a coupling. The internal cavity cross-sectional shape of the sleeve and the shape of the slider are both convex.

[0007] Furthermore, one end of the adjusting handwheel is threadedly connected to a limiting screw, the end of the limiting screw passes through the adjusting handwheel, and the sleeve has limiting holes arranged in a ring at equal intervals on the side near the adjusting handwheel, with the end of the limiting screw inserted into one of the limiting holes.

[0008] Furthermore, the rotating mechanism includes a connecting plate, which is fixedly connected to the top of the sleeved slide tube. A turntable is rotatably connected to the top of the connecting plate, and a connecting block is fixedly connected to the top of the turntable. The mounting components are arranged in a ring at equal intervals and fixedly connected to the outside of the connecting block.

[0009] Furthermore, the installation assembly includes mounting base blocks, which are arranged in a ring at equal intervals and fixedly connected to the outside of the connecting circular block. A mounting sleeve is fitted onto the outside of each mounting base block, and the mounting sleeve is installed on the outside of the mounting base block via mounting screws. An outer ring rail is fixedly connected to the outside of the mounting sleeve, and the sealing connector is rotatably connected to the inside of the outer ring rail. During use, sealing connectors with different sizes and shapes of fittings can be pre-fitted onto the mounting base blocks using mounting sleeves, and then installed on the outside of each mounting base block using mounting screws. This allows a single oblique tee to adapt to various types of external pipe structures, providing better overall flexibility. Its detachable design further enhances its versatility.

[0010] Furthermore, both the mounting screw and the limiting screw are hand-tightening screws, and mounting flanges are fixedly installed at both ends of the tee main pipe.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, by setting up installation components and standardized tee main and branch pipes, a single oblique tee can be adapted to be equipped with multiple threaded joints of different sizes, realizing the detachable assembly of sealing plugs of different specifications. There is no need to customize the whole tee fitting for different branch pipe specifications. Only the corresponding sealing plugs are required to complete the adaptation. This achieves the effects of reducing production and manufacturing costs, shortening the production cycle, and improving the overall adaptability. It solves the problem in the existing technology that the variety of branch pipe specifications requires the separate development of molds for customized production, resulting in poor universality and interchangeability of pipe fittings and difficulty in meeting the flexible adaptation needs of pipeline construction and maintenance. 2. During the application of this technical solution, by setting up a rotating mechanism, a telescopic mechanism, and a hand-tightening adjustment structure, and with multiple threaded joints of different sizes adapted to a single oblique tee, it is possible to quickly switch and adapt to different specifications of branch pipes during use. A single oblique tee can be compatible with multiple specifications of connection without the need for additional tools. This achieves the effects of improving the efficiency of temporary connection operations, reducing the cost of carrying, transporting and managing pipes, and enhancing the overall adaptability. It solves the problem in the existing technology that temporary connection scenarios require carrying multiple pipe fittings of different specifications, which can easily lead to connection delays due to missing specifications and cannot meet the rapid response needs of emergency repair scenarios.

Detailed Implementation

[0014] 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. Example 1

[0015] A slanted tee includes a main tee pipe 1, a secondary branch pipe 2 welded to the top of the main tee pipe 1, and a convertible connector 3 fixedly installed on the top of the secondary branch pipe 2. The convertible connector 3 includes a fixing plate 31 and a sleeve connector 32. The fixing plate 31 is fixedly connected to the top of the secondary branch pipe 2. A telescopic mechanism 33 is fixedly installed on the side of the fixing plate 31 near the main tee pipe 1. A rotating mechanism 34 is fixedly installed on the moving end of the telescopic mechanism 33. Installation components 35 are arranged in a ring at equal intervals on the outer side of the rotating mechanism 34. A sealing connector 36 is rotatably connected to the inner side of the sleeve connector 32, which is fixedly connected to the end of the secondary branch pipe 2 away from the tee main pipe 1. The inner end of a sealing connector 36 is inserted into the sleeve connector 32. Threaded connectors 37 of different sizes are fixedly connected to the outer sides of each sealing connector 36. During application, this device, through the use of convertible connectors 3, in conjunction with a telescopic mechanism 33, a rotating mechanism 34, an installation component 35, sealing connectors 36, and threaded connectors 37 of different sizes, allows for the selection of the branch pipe to be connected based on its specifications, using the rotating mechanism... The mounting components 35 and sealing connectors 36 arranged in an outer ring are rotated by the 34th motor, aligning the sealing connectors 36 connected to the threaded connectors 37 of corresponding sizes with the sleeve connectors 32. Then, the rotating mechanism 34 and the sealing connectors 36 are moved by the telescopic mechanism 33, so that the inner end of the sealing connectors 36 is inserted into the sleeve connectors 32. At this time, the sealing connectors 36 and the secondary branch pipe 2 are connected through the sleeve connectors 32. Then, the external branch pipe is connected to the corresponding threaded connectors 37 to complete the fluid diversion and transportation. If different specifications of branch pipes need to be connected, the above rotation adjustment and telescopic connection are repeated. Simply switch to the corresponding size threaded connector 37. This structural design allows a single oblique tee to adapt to various branch pipe specifications without the need for custom-made oblique tees for different branch pipe specifications. This effectively improves the adaptability and flexibility of the device, reduces the need for reserves of various oblique tees during pipeline construction and maintenance, simplifies the operation process when connecting different branch pipes, avoids connection delays caused by mismatched pipe specifications, and solves the problem of poor adaptability and the need for specific customization of oblique tees in existing technologies. This ensures efficient and smooth branch connections in fluid transport pipeline networks.

[0016] Combination Figures 1-4As shown, the telescopic mechanism 33 includes a sleeve 331, which is fixedly connected to the side of the fixed plate 31 near the tee main pipe 1. A lead screw 332 is rotatably connected inside the sleeve 331. An adjusting component 333 is provided at the bottom end of the sleeve 331. The top of the adjusting component 333 is connected to the bottom of the lead screw 332. A slider 334 is threadedly connected to the outer surface of the lead screw 332. The slider 334 is slidably connected inside the sleeve 331. A sleeved slide tube 335 is fixedly connected to the top of the slider 334. A rotating mechanism 34 is rotatably connected to the top of the sleeved slide tube 335. The sleeved slide tube 335 slides inside the sleeve 331. The adjustment assembly 333 includes an adjustment handwheel 3331, which is rotatably connected to the bottom end of the sleeve 331. The top of the adjustment handwheel 3331 is connected to the bottom of the lead screw 332 via a coupling. The internal cavity cross-sectional shape of the sleeve 331 and the shape of the slider 334 are both convex. One end of the adjustment handwheel 3331 is threadedly connected to a limit screw 3332, and the end of the limit screw 3332 passes through the adjustment handwheel 3331. Limit holes 3333 are arranged in a ring at equal intervals on the side of the sleeve 331 near the adjustment handwheel 3331, and the end of the limit screw 3332 is inserted into the inside of one of the limit holes 3333.

[0017] In the above-described embodiments of this application, the device, during application, comprises a sleeve 331, a lead screw 332, a slider 334, a sleeve slide tube 335, and an adjustment assembly 333 including an adjustment handwheel 3331, a coupling, and a limiting screw 3332. During use, rotating the adjustment handwheel 3331, via the coupling, drives the lead screw 332 inside the sleeve 331 to rotate. The rotation of the lead screw 332 drives the threaded slider 334 to slide smoothly inside the sleeve 331. Simultaneously, the sliding slider 334 drives the top sleeve slide tube 335 to slide synchronously along the inner side of the sleeve 331. The rotating mechanism 34 connected to the top of the sleeve slide tube 335 also moves synchronously, thus achieving precise telescopic adjustment. Once the telescopic adjustment is complete, simply rotate the limiting screw 3332 at one end of the adjustment handwheel 3331, allowing the end of the limiting screw 3332 to insert into the sleeve 331. The position of the adjusting handwheel 3331 can be fixed within the corresponding limiting hole 3333, preventing the lead screw 332 from accidentally rotating and changing the telescopic state during subsequent use. At the same time, the convex shape of the internal cavity of the sleeve 331 and the slider 334 can effectively limit the sliding trajectory of the slider 334, preventing the slider 334 from deflecting during sliding and ensuring the stability of telescopic adjustment. The sleeved slide tube 335 covers the outside of the lead screw 332 when sliding, and can also protect the lead screw 332, preventing impurities from entering and affecting the transmission effect. This structural design makes the entire telescopic adjustment process precise and easy to operate, and the fixed state after adjustment is also very reliable. It can effectively ensure the docking accuracy achieved by subsequent cooperation with the rotating mechanism 34, and solve the problem of unstable adjustment and easy loosening of the telescopic mechanism 33 in the prior art, which leads to docking deviation. It improves the structural stability and adjustment reliability of the overall device during use. Example 2

[0018] Combination Figures 3-4 As shown, the rotating mechanism 34 includes a connecting plate 341, which is fixedly connected to the top of the sleeved slide tube 335. A turntable 342 is rotatably connected to the top of the connecting plate 341. A connecting block 343 is fixedly connected to the top of the turntable 342. The mounting assembly 35 is arranged in a ring at equal intervals and fixedly connected to the outside of the connecting block 343. The mounting assembly 35 includes a mounting base 351, which is arranged in a ring at equal intervals and fixedly connected to the outside of the connecting block 343. A mounting sleeve 352 is sleeved on the outside of the mounting base 351. The mounting sleeve 352 is installed on the outside of the mounting base 351 by a mounting screw 38. An outer ring rail 353 is fixedly connected to the outside of the mounting sleeve 352. The sealing plug 36 is rotatably connected to the inside of the outer ring rail 353. The mounting screw 38 and the limiting screw 3332 are both hand-tightened screws. Mounting flanges 4 are fixedly installed at both ends of the tee main pipe 1.

[0019] In the above-described embodiments of this application, the device, through the arrangement of a connecting plate 341, a turntable 342, a connecting block 343, an installation assembly 35, a sealing connector 36, a hand-tightening installation screw 38, and an installation flange 4, allows the connecting plate 341 and the turntable 342 to rotate synchronously, thereby adjusting the position of the sealing connector 36 on different installation assemblies 35 to meet subsequent docking requirements. The installation assembly 35 assembles the sealing connector 36 through the cooperation of the installation base 351 and the installation sleeve 352. The installation sleeve 35 and the installation base 351 are fixed by the hand-tightening installation screw 38, making the operation convenient and painless. Additional tools are required, and the sealing plug 36 is rotatably connected to the outer ring rail 353 outside the mounting sleeve 352. The angle can be finely adjusted during docking to ensure smooth docking. At the same time, the mounting flanges 4 at both ends of the tee main pipe 1 can achieve a stable docking between the device and the main pipeline. The hand-tightening mounting screw 38 cooperates with the limit screw 3332 to further improve the convenience of overall operation. This structural setting can flexibly adjust the position of the sealing plug 36, and the assembly and disassembly of the sealing plug 36 are more convenient. It can quickly adapt to docking requirements of different specifications, while ensuring the stability of the connection between the device and the main pipeline. It solves the problems of inflexible rotation adjustment, cumbersome component assembly, and poor docking adaptability in the existing technology, and improves the overall flexibility and ease of operation of the device.

[0020] The working principle and advantages of this utility model are as follows: The usage process of this technical solution follows a reasonable sequence of pre-assembling the adapter, fixing the tee main pipe 1, adjusting the mating sealing connector 36, and completing the external branch pipe connection. The coordinated action of each structure achieves efficient and stable branch pipe connection. First, the adapter is pre-assembled. By setting the installation component 35, the sealing connectors 36 of different specifications can be detachably assembled. The installation base block 351 provides support for the assembly of the sealing connector 36. After the installation sleeve 352 is put on, the sealing connector 36 can be securely assembled with the installation screw 38. When the sealing connector 36 with the corresponding threaded connector 37 is selected, the installation sleeve 352 is put on the outside of the installation base block 351, and then the connection between the sealing connector 36 and the installation component 35 is completed by locking it with the installation screw 38. 38 adopts a hand-tight design, which can be assembled without additional tools. Different specifications of sealing plugs 36 can be assembled on multiple mounting bases 351 according to actual needs, so that a single oblique tee can be adapted to multiple branch pipe specifications in advance. After pre-assembly, the tee main pipe 1 is fixedly installed. The mounting flange 4 is used to fix the entire oblique tee to the main pipe. The tee main pipe 1 is precisely installed at the node where the branch pipe needs to be branched from the main pipe through the mounting flange 4, and the positioning and fixing of the main structure can be completed. The tee main pipe 1, as the main channel for fluid transportation, adopts a standardized structural design and can be directly adapted to the existing standardized main pipe without additional customization. The secondary branch pipe 2 is used to realize the diversion and guidance of fluid, which can guide the fluid in the main pipe to the convertible connector 3, providing a stable fluid channel for subsequent branch pipe connection. After the tee main pipe 1 is fixed, the adjustment and docking stage of the sealing connector 36 begins. The orientation of different sealing connectors 36 can be adjusted by the rotating mechanism 34 to precisely align them with the sleeve connector 32. Rotating the turntable 342 drives the connecting block 343 to rotate synchronously, thereby driving the installation assembly 35 and the sealing connector 36 to rotate as a whole. When the turntable 342 is rotated until the corresponding specification of the sealing connector 36 is aligned with the sleeve connector 32, the orientation adjustment of the sealing connector 36 is complete. Subsequently, the telescopic mechanism 33 drives the sealing connector 36 to dock with the sleeve connector 32. The adjusting assembly 333 drives the lead screw 332 to rotate. When the lead screw 332 rotates, it drives the slider 334 to move axially along the inside of the sleeve 331. The movement of the slider 334 drives the sleeve slide tube 335 to move synchronously. The sleeve slide tube 335 covers the outside of the lead screw 332, providing dust protection and preventing impurities from entering and affecting the transmission of the lead screw 332. The sleeve 331 and the slide tube... Block 334 adopts a convex cross-section design to prevent the slider 334 from deflecting during sliding and ensure sliding stability. When the adjusting handwheel 3331 is rotated to drive the lead screw 332 to rotate, the slider 334 will drive the sleeve slide tube 335 to move closer to the sleeve joint 32, thereby driving the rotating mechanism 34 and the sealing plug 36 to move synchronously until the inner end of the sealing plug 36 is inserted into the sleeve joint 32. At this time, the sealing plug 36 forms a sealed connection with the sleeve joint 32 through the sealing structure, and the sleeve joint 32 is connected to the outer end of the secondary branch pipe 2, completing the channel docking of the sealing plug 36 and the secondary branch pipe 2. After the sealing plug 36 and the sleeve joint 32 are docked, the limiting screw 3332 is rotated so that its end is inserted into the corresponding limiting hole 3333, which can realize the positioning and fixing of the adjusting handwheel 3331, preventing the lead screw 332 from rotating unexpectedly during subsequent use, causing the sealing plug 36 and the sleeve joint 32 to disengage. Finally, the connection with the external branch pipe is completed. Threaded connector 37 is used to achieve threaded connection with the external branch pipe. Align the external branch pipe with the corresponding specification of threaded connector 37 and tighten it through the threaded engagement to form a stable connection between the external branch pipe and the sealing plug 36. At this time, the fluid in the main pipeline enters the external branch pipe sequentially through the tee main pipe 1, secondary branch pipe 2, sleeve connector 32, sealing plug 36, and threaded connector 37, realizing the directional diversion and transportation of fluid. If the specification of the connecting branch pipe needs to be changed later, simply rotate the limiting screw 3332 in the reverse direction to disengage it from the limiting hole 3333, and then rotate the adjusting handwheel 3331 to drive the sleeve slide 335 to move the sealing plug 36 outward, so that the sealing plug 36 disengages from the sleeve. With connector 32 installed, the turntable 342 is rotated to adjust the corresponding specification of the sealing plug 36 and align it with connector 32. Repeating the above docking operation allows for rapid switching and docking of branch pipes of different specifications. This technical solution achieves detachable assembly of sealing plugs 36 of different specifications through the installation component 35. Individual tee main pipe 1 and branch pipe 2 are produced using a standardized structure, eliminating the need for customized integral tee fittings for different branch pipe specifications. Only the corresponding specification of sealing plug 36 needs to be provided, eliminating the need for separate mold development, significantly reducing production costs, and avoiding the extended cycle caused by customized production. By assembling multiple threaded connectors 37 and sealing plugs 36 of different specifications on the outside of the rotating mechanism 34, and cooperating with the rotation... The orientation adjustment mechanism 34 and the docking drive of the telescopic mechanism 33 can quickly switch to a docking structure suitable for the current branch pipe specification without replacing the entire oblique tee. The detachable design of the installation component 35 also allows for the addition, removal, or replacement of the sealing plug 36 specification according to actual needs, further improving the versatility and interchangeability of the overall structure. It can flexibly adapt to different branch pipe connection needs during pipeline construction and maintenance. A single oblique tee can be compatible with multiple branch pipe specifications for docking, eliminating the need to carry multiple different specifications of pipe fittings, significantly reducing the carrying, transportation, and management costs in temporary scenarios. Each adjustment mechanism adopts a hand-tight design, which can complete specification switching and docking operations without additional tools, improving the operational efficiency of temporary docking and avoiding compatibility issues due to different specifications. The system can meet the rapid response needs of scenarios such as emergency repair of municipal pipe networks, temporary water supply for building projects, and emergency rescue diversion, and can prevent docking delays caused by missing grids or complex operations. The sliding block 334 with a convex cross section in the telescopic mechanism 33 cooperates with the sleeve 331 to prevent the sliding block 334 from sliding and deflecting, ensuring that the sealing plug 36 is accurately docked with the sleeve joint 32. The cooperation between the limiting screw 3332 and the limiting hole 3333 can fix the state of the telescopic mechanism 33 and prevent the sealing plug 36 from accidentally disengaging after docking. The sealing cooperation between the sealing plug 36 and the sleeve joint 32, as well as the threaded connection between the threaded joint 37 and the external branch pipe, all ensure the sealing performance during the fluid transportation process, prevent fluid leakage, and ensure the stability of the directional diversion and transportation of fluid.The detachable design of the mounting component 35 allows the sealing connector 36 to be disassembled, maintained, or replaced separately without replacing the entire oblique tee. The dust protection provided by the sliding tube 335 to the lead screw 332 reduces the impact of impurities on the transmission of the telescopic mechanism 33, lowers the probability of mechanism failure, and improves the service life and maintenance convenience of the overall structure. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0021] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
