[0003] The aforementioned patent documents and prior art have the following technical problems:

[0004] 1. Traditional tee bends mostly use bolt or flange connections. Bolted connections require tightening multiple bolts one by one, which is cumbersome and time-consuming, especially in narrow spaces or large-scale pipeline installation projects, making construction difficult and inefficient.

[0005] 2. Existing tee bends are usually designed and manufactured for specific pipe diameters. One type of tee bend can only be used with one or a few similar pipe diameters. When a project requires connecting pipes of various diameters, a large number of different types of tee bends must be stocked. This not only increases material procurement costs but also occupies a lot of storage space, resulting in poor compatibility. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing tee pipes, such as cumbersome installation and poor compatibility with pipes of different diameters, by proposing a tee pipe that can be assembled quickly.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a quick-assembly tee pipe, comprising a tee bend and a connecting pipe, wherein the end of the tee bend is provided with a mounting female, and an adjusting clamp is engaged on the surface of the mounting female. A limiting and pressing component is provided on the outside of the end of the tee bend, and the limiting and pressing component is connected to the surface of the adjusting clamp. The adjusting clamp has two sets of centrally symmetrical components, and adjacent ends of the adjusting clamps are slidably engaged. A positioning hole is provided on the circumference of the surface of the mounting female, and the positioning hole is distributed within different circumferential diameter ranges of the surface of the mounting female. A positioning pin is provided on the back of the adjusting clamp, and the positioning pin engages with the positioning hole. A conical sealing plug is provided on the inner wall of the adjusting clamp, and the outer wall of the connecting pipe abuts against the inner wall of the conical sealing plug.

[0008] Preferably, both ends of the adjusting clamp are provided with guide arc grooves, and an adjusting arc plate is provided inside one end of the guide arc groove. An adjusting shaft is movably connected to one end of the adjusting arc plate, and the adjusting shaft is fixed to one end surface inside the guide arc groove.

[0009] Preferably, a spring pin is provided on the surface of the adjusting arc plate away from the guide shaft, and a positioning pin hole is provided on the circumference of the outer surface of the adjusting clamp, and the positioning pin hole and the spring pin are engaged with each other.

[0010] Preferably, the mounting female is provided with a threaded end at one end away from the positioning hole, and the end of the threaded end is threadedly connected to the inner wall of the tee bend. The other end of the mounting female is provided with a positioning end, and the positioning hole is formed on the surface of the positioning end.

[0011] Preferably, the outer wall of the conical sealing plug abuts against the inner wall of the adjusting clamp, the outer wall of the conical sealing plug is provided with a mounting T-block, the inner wall of the adjusting clamp is provided with a mounting T-groove, and the mounting T-block is located inside the mounting T-groove.

[0012] Preferably, the limiting and pressing assembly includes a pressing arm and a fixed shaft seat. The fixed shaft seat is welded to the surface of the tee bend. A connecting arm is axially connected to the surface of the fixed shaft seat. The ends of the connecting arm are respectively axially connected to a pressing arm and a limiting arm. A positioning arm is provided on the outer wall of the adjusting clamp. The surfaces of the limiting arm and the positioning arm overlap.

[0014] Beneficial effects

[0015] In this invention, a tee bend is connected via a mounting base. The connecting pipe is clamped by an adjusting clamp and then inserted into the mounting base. A limiting and clamping component connected to the outside further tightens the adjusting clamp, compressing the conical sealing plug during clamping to enhance the sealing effect and achieve rapid fixing of the connecting pipe. This method replaces traditional bolt and flange connections with a snap-fit ​​clamp for rapid assembly of the connecting pipe. The snap-fit ​​clamping connection requires no special tools, making operation extremely simple and significantly reducing the connection and disassembly time between the tee bend and the connecting pipe, thus significantly improving construction efficiency. It is particularly suitable for engineering scenarios requiring frequent pipeline installation, maintenance, or modification. Simultaneously, during the clamping process, the conical sealing plug on the inner wall of the adjusting clamp is compressed, tightly fitting against the outer wall of the connecting pipe, further enhancing the sealing effect and effectively preventing fluid leakage. This ensures the safe and stable operation of the pipeline system, reduces fluid loss, environmental pollution, and potential safety accidents caused by poor sealing, and lowers subsequent maintenance costs and risks.

[0016] In this invention, the surface of the tee bend is connected to the adjusting clamp via a positioning hole on the surface of the mounting base. The engagement position of the two adjusting clamps can be adjusted according to the actual diameter of the connected pipe, thereby adapting the inner diameter of the adjusting clamp to the connected pipe. After adjustment, the tee bend is inserted according to the diameter of the positioning hole. There is no need to replace the tee bend. The engagement position of the two adjusting clamps can be flexibly adjusted according to the actual diameter of the connected pipe, thus precisely adjusting the inner diameter of the adjusting clamp to adapt to connected pipes of different diameters. This greatly improves the versatility and flexibility of the tee connector, avoids the need to stock large quantities of different models of tee bends due to differences in pipe diameter, reduces material procurement costs and inventory pressure, improves resource utilization, and brings great convenience to engineering construction and pipeline system maintenance.

Detailed Implementation

[0027] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0028] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0030] Reference Figure 1-8 A quick-assembly tee pipe includes a tee bend 1 and a connecting pipe 2. The tee bend 1 serves as the main structure, creating multi-directional fluid channels that allow fluid to be transmitted, split, or merged between different paths. It is the core framework of the entire connector, supporting other components and ensuring the stability and functionality of the overall structure. The connecting pipe 2 serves as an extension of the fluid transmission, connecting the tee bend 1 to other equipment, pipes, or systems to realize the transportation of fluid between different areas or equipment, completing specific process flows or meeting actual usage requirements.

[0031] The mounting female seat 3 serves as a transitional component connecting the tee bend 1 and the connecting pipe 2. On one hand, it provides the installation foundation and positioning basis for the adjusting clamp 6. On the other hand, through its structural design, it achieves a stable connection with the tee bend 1 and a precise connection with the connecting pipe 2, while also enhancing the sealing performance of the connection. The tee bend 1 has a mounting female seat 3 at one end, and the adjusting clamp 6 is fitted onto the surface of the mounting female seat 3. The end of the mounting female seat 3 furthest from the positioning hole 303 has a threaded end 301, which is threaded to the inner wall of the tee bend 1. The other end of the mounting female seat 3 has a positioning end 302, with positioning holes 303 formed on its surface. Positioning holes 303 are distributed around the circumference of the mounting female seat 3, ranging from different circumferential diameters. The adjusting clamp 6 has a positioning pin 304 on its back, which engages with the positioning hole 303. One end of the pin is threaded to the inner wall of the tee bend 1 via the threaded end 301, ensuring the firmness and stability of the installation. The positioning end 302 at the other end has a positioning hole 303 on its circumference, which cooperates with the positioning pin 304 on the back of the adjusting clamp 6 to determine the installation position and angle of the adjusting clamp 6, thereby indirectly determining the connection position and sealing degree of the connecting pipe 2. During installation, the mounting female seat 3 is first screwed into the end of the tee bend 1 through the threaded end 301, then the connecting pipe 2 is inserted into the mounting female seat 3, and then the adjusting clamp 6 is put on the connecting pipe 2 and its positioning pin 304 is engaged with the positioning hole 303 to complete the initial positioning. In the subsequent compression and sealing process, the mounting female seat 3 provides support and positioning reference for the entire connection structure, ensuring the accuracy and reliability of the connection, improving the stability and accuracy of the connection between the tee bend 1 and the connecting pipe 2, facilitating the installation and positioning of the adjusting clamp 6, making the entire connection process more orderly and reliable, and through the cooperation of the positioning hole 303 and the positioning pin 304, it can adapt to the installation requirements of connecting pipes 2 with different diameters, enhancing the versatility of the tee bend 1.

[0032] The adjusting clamp 6 is mainly used to clamp the connecting pipe 2, making it fit tightly against the mounting base 3. Simultaneously, the conical sealing plug 7 on the inner wall achieves a seal at the connection point. It can be adjusted according to the diameter of the connecting pipe 2 to accommodate different specifications, making it a key component for achieving quick and convenient connection. The adjusting clamp 6 has two centrally symmetrical sets, with adjacent adjusting clamps 6 slidingly engaging at their ends. Both ends of the adjusting clamp 6 have guide arc grooves 601. An adjusting arc plate 605 is located inside one end of the guide arc groove 601. An adjusting shaft 603 is movably connected to one end of the adjusting arc plate 605, and the adjusting shaft 603 is fixed to one end surface inside the guide arc groove 601. A spring pin 602 is located on the end surface of the adjusting arc plate 605 away from the guide shaft. The guide arc groove 601 provides guidance and limitation for the sliding of the adjusting arc plate 605 at the end of the adjusting clamp 6, ensuring that the adjusting arc plate 605 can move smoothly in a predetermined direction, thereby achieving… The inner diameter of the adjusting clamp 6 is finely adjusted to better fit the diameter of the connecting pipe 2. The adjusting arc plate 605 changes the opening degree of the end of the adjusting clamp 6 by sliding in the guide arc groove 601, thereby adjusting the inner diameter of the adjusting clamp 6. This allows the adjusting clamp 6 to clamp the connecting pipe 2 more precisely, improving the stability and sealing of the connection. The adjusting shaft 603 serves as the movable connecting shaft of the adjusting arc plate 605, allowing the adjusting arc plate 605 to rotate around it and achieve sliding adjustment at one end in the guide arc groove 601. This provides a flexible operating method for adjusting the inner diameter of the adjusting clamp 6. The outer surface of the adjusting clamp 6 is provided with a positioning pin hole 604, which engages with the spring pin 602. The two sets of centrally symmetrical adjusting clamps 6 achieve the function of encircling the connecting pipe 2 through the sliding engagement of their ends. When the conical sealing plug 7 on its inner wall is squeezed by the limiting and pressing component 4, it will tightly fit against the outer wall of the connecting pipe 2, forming a reliable seal. The positioning pin 304 on the back of the adjusting clamp 6 engages with the positioning holes 303 within different circumferential diameter ranges on the surface of the mounting base 3. The engagement position can be adjusted according to the diameter of the connecting pipe 2, changing the inner diameter of the adjusting clamp 6 to fit the connecting pipe 2. During the installation of the connecting pipe 2, the positioning pin 304 of the adjusting clamp 6 is inserted into the corresponding positioning hole 303 according to the diameter of the connecting pipe 2. Then, the adjusting clamp 6 is put on the connecting pipe 2 and its end is slidably engaged. After that, the limiting and clamping assembly 4 clamps the adjusting clamp 6, so that the conical sealing plug 7 is in close contact with the outer wall of the connecting pipe 2, completing the connection and sealing operation. When it is necessary to replace the connecting pipe 2 with a different diameter, it is only necessary to adjust the engagement position of the positioning pin 304 with the different positioning holes 303. This achieves quick clamping and sealing of the connecting pipe 2 without the need for traditional connection tools such as bolts and flanges, greatly improving the speed of connection and disassembly, and reducing labor intensity and tool costs. Meanwhile, the connecting pipe 2, which can adapt to various pipe diameters, improves the adaptability of the tee bend 1, reduces the need to replace the tee bend 1 due to different specifications of the connecting pipe 2, and improves the utilization rate of equipment and materials.

[0033] The limiting clamping assembly 4 applies clamping force to the adjusting clamp 6, enabling the adjusting clamp 6 to tightly clamp the connecting pipe 2 and ensuring sufficient sealing pressure between the conical sealing plug 7 and the outer wall of the connecting pipe 2, thus ensuring the firmness and sealing of the connection. Structurally, it also serves to connect and stabilize the adjusting clamp 6. The limiting clamping assembly 4 is located on the outer side of the end of the tee bend 1 and is connected to the surface of the adjusting clamp 6. The limiting clamping assembly 4 includes a clamping support arm 403 and a fixed shaft seat 401. The fixed shaft seat 401 is welded to the surface of the tee bend 1, and a connecting support arm 402 is axially connected to the surface of the fixed shaft seat 401. The ends of the connecting support arm 402 are respectively... The axial connection is equipped with a clamping support arm 403 and a limiting support arm 404. The outer wall of the adjusting clamp 6 is provided with a positioning support arm 405. The surfaces of the limiting support arm 404 and the positioning support arm 405 overlap. An adjusting arc groove 5 is formed on the surface of the adjusting clamp 6, and the end of the positioning support arm 405 slides within the adjusting arc groove 5. Positioning supports 405 are provided on the surfaces of both adjusting clamps 6. The limiting and clamping assembly 4 is located on both sides of the end of the tee bend 1 and consists of components such as the clamping support arm 403, a fixed shaft seat 401, a connecting support arm 402, a limiting support arm 404, and a positioning support arm 405. The fixed shaft seat 401 is welded to the surface of the tee bend 1, serving as the axial connection base for the connecting support arm 402. The connecting support arm 402 is axially connected to both the clamping support arm 403 and the limiting support arm 404, applying pressure to the adjusting clamp 6 through the movement of the clamping support arm 403. The limiting arm 404 overlaps with the positioning arm 405 on the outer wall of the adjusting clamp 6, restricting the positional movement of the adjusting clamp 6 and ensuring uniform transmission and stability of the clamping force. When it is necessary to connect the connecting pipe 2, the clamping arm 403 is rotated around the axis, and the connecting arm 402 drives the limiting arm 404 to apply pressure to the positioning arm 405, thereby causing the adjusting clamp 6 to clamp the connecting pipe 2. After clamping, the clamping arm 403 is located on the surface structure of the hollow Ajin tee bend 1. The clamping arm 403, the limiting arm 404, and the connecting arm 402 form a nearly straight locking structure, such as the existing glass The snap-fit ​​structure of the glass sealing tank is similar. During this process, as the end of the positioning support arm 405 slides in the adjusting arc groove 5 on the surface of the adjusting clamp 6, the clamping force can be evenly distributed on the adjusting clamp 6, ensuring that the connecting pipe 2 is stably clamped and the conical sealing plug 7 effectively seals, providing reliable clamping force and ensuring the firmness and sealing of the connection between the adjusting clamp 6 and the connecting pipe 2, effectively preventing fluid leakage. Through ingenious structural design, the clamping process is stable and uniform, reducing the risk of sealing failure or damage to the connecting pipe 2 due to uneven local pressure, and improving the quality and reliability of the connection.

[0034] The conical sealing plug 7 serves as a crucial sealing component at the connection between the connecting pipe 2 and the tee bend 1. Its conical structure allows it to fit tightly against the outer wall of the connecting pipe 2 when squeezed by the limiting and clamping assembly 4, filling the gap between the connecting pipe 2 and the adjusting clamp 6, preventing fluid leakage, and ensuring a tight seal. The adjusting clamp 6 has a conical sealing plug 7 on its inner wall, with the outer wall of the connecting pipe 2 abutting against the inner wall of the conical sealing plug 7, and the outer wall of the conical sealing plug 7 abutting against the inner wall of the adjusting clamp 6. The outer wall of the conical sealing plug 7 has a mounting T-shaped block 9, and the inner wall of the adjusting clamp 6 has a mounting T-shaped groove 8. The mounting T-shaped block 9 is located inside the mounting T-shaped groove 8, with its outer wall abutting against the inner wall of the adjusting clamp 6. By engaging the mounting T-shaped block with the mounting T-shaped groove on the inner wall of the adjusting clamp 6, the block is fixed within the adjusting clamp 6. When the adjusting clamp 6 is pressed by the limiting and tightening assembly 4, the conical sealing plug 7 deforms along the shape of the outer wall of the connecting pipe 2, making the sealing surface fit tightly and forming a reliable sealing barrier. After the connecting pipe 2 is inserted into the adjusting clamp 6, as the limiting and tightening assembly 4 presses against the adjusting clamp 6, the conical sealing plug 7 is gradually squeezed and deformed, and the contact pressure between it and the outer wall of the connecting pipe 2 continuously increases until it reaches a sealing pressure that can effectively prevent fluid leakage. Throughout the entire use process, it maintains a sealed state, and even under conditions such as fluid pressure fluctuations or pipeline vibration, it can maintain good sealing performance, providing a highly efficient sealing effect, ensuring leak-free fluid transmission at the connection point, and improving the operational safety and stability of the entire pipeline system. Its cooperation structure with the adjusting clamp 6 and the connecting pipe 2 is simple and effective, easy to install and maintain, and reduces sealing costs and maintenance difficulty. Specific Implementation Example 2:

[0036] Reference Figure 1-8 Based on the content of the above specific embodiments, the following content is further disclosed:

[0037] Spring pin 602 and positioning pin hole 604: After the adjusting arc plate 605 is adjusted to the appropriate position, the spring pin 602 engages with the positioning pin hole 604, fixing the adjusting arc plate 605 in its current position to prevent displacement due to vibration or other factors during use, ensuring the stability of the inner diameter of the adjusting clamp 6, and maintaining the clamping and sealing state of the connecting pipe 2. When it is necessary to finely adjust the inner diameter of the adjusting clamp 6 to fit the connecting pipe 2, push the adjusting arc plate 605 so that it slides around the adjusting shaft 603 in the guide arc groove 601, changing the distance at the end of the adjusting clamp 6. After being adjusted to the appropriate position, the spring pin 602 engages with the positioning pin hole 604 under the action of the spring force, locking the position of the adjusting arc plate 605. When there is a slight difference between the pipe diameter of the connecting pipe 2 and the initial inner diameter of the adjusting clamp 6, the inner diameter of the adjusting clamp 6 can be finely adjusted by operating the adjusting arc plate 605. First, release the spring pin 602 from the positioning pin hole 604, adjust the position of the adjusting arc plate 605, and then re-lock it so that the adjusting clamp 6 can better clamp the connecting pipe 2, improve the adaptability and reliability of the connection, improve the adaptability and adjustment accuracy of the adjusting clamp 6 to changes in the diameter of the connecting pipe 2, and to a certain extent compensate for the problem of loose connection caused by processing errors or slight differences in the specifications of the connecting pipe 2, further enhancing the versatility and reliability of the entire tee connector and reducing the risk of fluid leakage caused by connection problems.

[0038] According to actual usage requirements, as shown in the content and attached diagram of Embodiment 1 above, the positioning pin 304 and the spring pin 602 are respectively set at the end of the adjusting clamp 6 and the end of the adjusting arc plate 605. In actual use, they can be set at the arc-shaped surface of the adjusting clamp 6 for easy pressing operation. At the same time, the spring pin 602 is simultaneously set at the arc-shaped position on the surface of the adjusting arc plate 605.

[0039] In summary:

[0040] 1. The tee bend 1 is connected to the mounting base 3 at one end, allowing the connecting pipe 2 to be clamped by the adjusting clamp 6 and inserted into the surface of the mounting base 3. The adjusting clamp 6 is then pressed by the limiting and clamping component 4 connected to the outside, and the conical sealing plug 7 is squeezed during the clamping process, further enhancing the sealing effect and achieving rapid fixation of the connecting pipe 2. This method changes the traditional bolt and flange connection, achieving rapid assembly of the connecting pipe 2 through a snap-fit ​​clamping method. The snap-fit ​​clamping connection does not require special tools, making the operation extremely simple and greatly shortening the connection and disassembly time between the tee bend 1 and the connecting pipe 2, significantly improving construction efficiency. It is especially suitable for engineering scenarios that require frequent pipeline installation, maintenance, or modification. At the same time, during the clamping process, the conical sealing plug 7 on the inner wall of the adjusting clamp 6 is squeezed and tightly fits against the outer wall of the connecting pipe 2, further enhancing the sealing effect, effectively preventing fluid leakage, ensuring the safe and stable operation of the pipeline system, reducing fluid loss, environmental pollution, and potential safety accidents caused by poor sealing, and lowering later maintenance costs and risks.

[0041] 2. The tee bend 1 connects to the adjusting clamp 6 via the positioning hole 303 on the surface of the mounting base 3. The engagement position of the two adjusting clamps 6 can be adjusted according to the actual diameter of the connected pipe 2, thereby adapting the inner diameter of the adjusting clamp 6 to the connected pipe 2. After adjustment, it is inserted according to the diameter of the positioning hole 303. There is no need to replace the tee bend 1. The engagement position of the two adjusting clamps 6 can be flexibly adjusted according to the actual diameter of the connected pipe 2, thereby accurately adjusting the inner diameter of the adjusting clamp 6 to adapt to connected pipes 2 of different diameters. This greatly improves the versatility and flexibility of the tee connector, avoids the situation of stocking a large number of different models of tee bend 1 due to the difference in the diameter of the connected pipe 2, reduces material procurement costs and inventory pressure, improves resource utilization, and brings great convenience to engineering construction and pipeline system maintenance.
