[0018] This invention provides a tee fitting for fire-fighting pipes. It has the following advantages:

[0019] 1. This fire-fighting pipe fitting uses a tee. Currently used tees are designed with the tee and connector as a single unit, making the angle and position of the tee unadjustable and increasing installation difficulty. Therefore, a separate connector, pressing mechanism, and clamping mechanism are implemented. The connector is divided into upper and lower parts, secured with bolts. During installation, the bolts can be loosened first, allowing the tee to rotate and adjust. The horizontal and vertical sections of the tee can also be fixed, facilitating alignment of subsequent pipe fittings and simplifying installation and maintenance. This design achieves the goal of easily separating the tee into a tee and connector, improving installation efficiency.

[0020] 2. This fire-fighting pipe fitting uses a tee fitting. A pressing mechanism is installed to press and fix the horizontal pipe position of the tee. During installation, the tee's angle needs to be adjusted to connect it to the pipe. Since tee sizes vary, the tee's position must be kept stable before pipe installation. Therefore, a pressing mechanism is installed to press and hold the top circumference of the horizontal pipe of the tee to resolve the issue of tee position changes. Furthermore, after using the connector, the rubber ring and lifting cylinder can be stretched or compressed to help them return to their original state, preventing deformation of the rubber material due to long-term use. This achieves the purpose of easily pressing and fixing the horizontal pipe position of the tee.

[0021] 3. This fire-fighting pipe fitting uses a tee. A clamping mechanism is incorporated to address the issue that, since the tee size varies and may not perfectly match the internal dimensions of the connector, dust and impurities can accumulate on the inner wall of the connector over time. The clamping mechanism, when rotated, facilitates the scraping of the inner walls of the head and core by the protective components, allowing for simple cleaning. This achieves the goal of easily cleaning the inner walls of the head and core.

[0022] 4. This fire-fighting pipe fitting uses a tee, which externally secures the tee's vertical section by incorporating protective components. Before installing the vertical section, the tee's position needs to be fixed; therefore, a clamping mechanism and a pressing mechanism are used to secure both the horizontal and vertical sections of the tee. Furthermore, after the vertical section is connected, both the vertical section and the tee's vertical section are doubly secured to prevent changes in pipe position and to ensure a more robust connection. This achieves the goal of easily pressing and securing the tee's vertical section. Attached Figure Description

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0033] like Figures 1-8 As shown, the present invention provides a technical solution, specifically including:

[0034] The upper buckle plate 3 has a connector 4 fixedly connected inside, and a first threaded frame 8 fixedly connected outside. The first threaded frame 8 has a bolt 7 threadedly connected inside.

[0035] The lower buckle plate 1 has a second threaded frame 2 externally fixedly connected to it, and the second threaded frame 2 is threadedly connected to the bolt 7.

[0036] The fire-fighting pipe fittings tee also include:

[0037] Pressing mechanism 5 is used to press and fix the horizontal pipe part of the tee. Pressing mechanism 5 is fixedly connected to the bottom of the upper buckle plate 3. Pressing mechanism 5 includes an arc plate 501 and a rubber ring 510. The bottom of the arc plate 501 is fixedly connected to a third telescopic rod 502. The arc plate 501 is fixedly connected to the bottom of the upper buckle plate 3, and the rubber ring 510 is fixedly connected to the inside of the upper buckle plate 3.

[0038] The clamping mechanism 6 is used to clamp and fix the vertical pipe part of the tee. The clamping mechanism 6 is fixedly connected to the top of the upper buckle plate 3. The clamping mechanism 6 includes an annular frame 601. A magnetic block is provided at the bottom of the annular frame 601. A sliding plate 602 and a positioning plate 604 are slidably connected inside the annular frame 601. The positioning plate 604 is made of magnetic material. A connecting strap 603 is fixedly connected to the outside of the sliding plate 602. The annular frame 601 is fixedly connected to the top of the upper buckle plate 3.

[0039] Multiple arc-shaped plates 501 are provided and arranged symmetrically. There are two of each of the first threaded frame 8 and the second threaded frame 2. The external thread of the bolt 7 is connected to a nut.

[0040] Before using the equipment, the upper clamp plate 3 and the lower clamp plate 1 are in a separate state. Manually insert the vertical pipe of the tee into the upper clamp plate 3, and manually align the lower clamp plate 1 with the upper clamp plate 3. Secure the upper clamp plate 3 and the lower clamp plate 1 using bolts 7 and nuts. Activate the pressing mechanism 5 and the clamping mechanism 6 to fix the positions of the horizontal and vertical pipes of the tee. Then, other pipes can be connected.

[0041] The connector 4 includes a gasket 401, a core 402 is fixedly connected inside the gasket 401, a head 403 is sleeved on the outside of the core 402, a triangular plate 404 is fixedly connected inside the head 403, multiple triangular plates 404 are provided, the triangular plates 404 are made of magnetic material, the core 402 is fixedly connected to the rubber ring 510, and the gasket 401 is fixedly connected inside the upper buckle plate 3.

[0042] The third telescopic rod 502 is externally fixedly connected to a fixing ring 507, and the fixing ring 507 is externally fixedly connected to a rubber ring 504. The top of the rubber ring 504 is fixedly connected to a spring rod 503, and the spring rod 503 is fixedly connected to the bottom of the rubber ring 510.

[0043] The third telescopic rod 502 is externally fixedly connected to an annular plate 505, the bottom of the annular plate 505 is fixedly connected to an adjusting column 506, and the bottom of the adjusting column 506 is fixedly connected to a compression ball.

[0044] A lifting cylinder 508 is slidably connected inside the rubber ring 504. A suction cup 509 is fixedly connected to the bottom of the lifting cylinder 508. The lifting cylinder 508 is made of rubber. A circular groove is opened inside the rubber ring 504, and the lifting cylinder 508 is located in the circular groove.

[0045] Before using the equipment, the third telescopic rod 502 is in the closed state, and the rubber ring 504 is outside the core 402. After fixing the positions of the upper buckle plate 3 and the lower buckle plate 1, open the third telescopic rod 502 to the appropriate stroke according to the size of the tee. The third telescopic rod 502 drives the rubber ring 504 to move downward. At this time, the elastic rod 503 is stretched until multiple suction cups 509 are attracted and fixed to the top of the tee horizontal tube. At this time, the rubber lifting cylinder 508 is pressed on the tee to fix the position of the tee horizontal tube.

[0046] If the tee is large, the third telescopic rod 502 and the elastic rod 503 will always be at their original length, the rubber ring 504 and the lifting cylinder 508 will be in a compressed state, and most of the lifting cylinder 508 will be inside the rubber ring 504.

[0047] The rubber ring 504 is under constant compression or tension, which can easily cause it to deform and be difficult to return to its initial state. Disassemble the tee, then manually adjust the length of the adjusting column 506 to move the compression ball downwards. Repeatedly open and close the third telescopic rod 502. When the third telescopic rod 502 moves the rubber ring 504 upwards, since the adjusting column 506 and the compression ball remain stationary, the compression ball gradually enters the lifting cylinder 508 and presses it downwards, causing the lifting cylinder 508 to return to its original shape. Because the top of the rubber ring 504 is fixed by the elastic rod 503 and the third telescopic rod 502, the deformation at the top of the rubber ring 504 is small, while the bottom is stretched, promoting the return of the rubber ring 504 to its original shape. When the third telescopic rod 502 is opened to its maximum stroke, the third telescopic rod 502 drives the rubber ring 504 to move downward. The rubber ring 504, the lifting cylinder 508 and the suction cup 509 gradually contact the bottom buckle plate 1, thereby squeezing the rubber ring 504 and the lifting cylinder 508, causing them to return to their original state.

[0048] A first telescopic rod 605 is fixedly connected to the top of the sliding plate 602. A swivel joint 606 is fixedly connected to the top of the first telescopic rod 605. An adjusting bent rod 607 is fixedly connected inside the swivel joint 606. A magnetic plate 608 is fixedly connected to the outside of the adjusting bent rod 607. A protective component 609 is fixedly connected to the bottom of the adjusting bent rod 607.

[0049] Before installing the tee, the first telescopic rod 605 and the adjusting bend rod 607 are at their original lengths, and the magnetic plate 608 is attached to the inner wall of the head 403, and is attracted and fixed to the triangular plate 404, which is made of magnetic material. When it is necessary to clean the inner wall of the head 403, the positioning plate 604 is manually rotated to separate the positioning plate 604 from the bottom magnetic block. At this time, the positioning plate 604 drives the connecting belt 603 and the sliding plate 602 to rotate inside the annular frame 601, which in turn drives the protective component 609 to rotate inside the head 403, thereby scraping and cleaning the inner wall of the head 403 and the core 402, causing impurities to move downwards.

[0050] When installing the tee, open the first telescopic rod 605. The first telescopic rod 605 drives the steering joint 606, the adjusting bend rod 607 and the protective component 609 to move upward. According to the size of the tee's vertical pipe section, manually adjust the length of the adjusting bend rod 607 to control the position of the protective component 609 and externally fix the tee's vertical pipe section.

[0051] The protective component 609 includes a semicircular plate 6091, a first locking rod 6092 is engaged with the outside of the semicircular plate 6091, and a second locking rod 6094 is engaged with the bottom of the semicircular plate 6091. Both the first locking rod 6092 and the second locking rod 6094 are covered with a shell, the outer surface of which is rough. An elastic strap 6093 is fixedly connected to the outside of the semicircular plate 6091. The semicircular plate 6091 is fixedly connected to the bottom of the adjusting rod 607.

[0052] The protective component 609 also includes a suspension rod 6095, which is an adjustable rod. An arc-shaped plate 6096 is fixedly connected to the outside of the suspension rod 6095. A rubber rod 6097 is fixedly connected to the outside of the arc-shaped plate 6096. Multiple rubber rods 6097 are provided. A second telescopic rod 6098 is fixedly connected to the bottom of the arc-shaped plate 6096. There are three arc-shaped plates 6096. The rubber rods 6097 on the outside of the three arc-shaped plates 6096 are of different sizes. The rubber rod 6097 on the outside of the bottom arc-shaped plate 6096 has the largest diameter. The rubber rods 6097 on the outside of the two upper arc-shaped plates 6096 have the same diameter, and both are smaller than the diameter of the bottom rubber rod 6097. The bottom arc-shaped plate 6096 is made of rubber. The suspension rod 6095 is snapped onto the outside of the adjusting bend rod 607.

[0053] The first locking rod 6092 and the second locking rod 6094 rotate with the protective component 609. The outer shell of the first locking rod 6092 begins to scrape the inner wall of the head 403, and the outer shell of the second locking rod 6094 begins to scrape the inner wall of the core 402. The impurities gradually move downward.

[0054] Activate multiple second telescopic rods 6098, which cause the two arc-shaped plates 6096 to move downwards. Manually adjust the adjusting rods 607 on both sides to the same length. The adjusting rods 607 move the two semi-circular plates 6091 towards the center until the bottom arc-shaped plate 6096 is outside the T-joint riser section, fixing the position of the T-joint riser section. At this point, the rubber rod 6097 outside the bottom arc-shaped plate 6096 is fixed to the outside of the T-joint riser section. Manually connect the pipe to the threaded connection inside the T-joint riser. readjust the adjusting rods 607 so that the three arc-shaped plates 6096 are respectively in contact with the pipe and the T-joint riser section. Reinforce the connection point; at this point, the bottom arc-shaped plate 6096 is under compression.

[0055] Working principle: Before using the equipment, the upper buckle plate 3 and the lower buckle plate 1 are in a separated state. Manually insert the vertical pipe of the tee into the upper buckle plate 3, and manually align the lower buckle plate 1 with the upper buckle plate 3. Then, use bolts 7 and nuts to fix the upper buckle plate 3 and the lower buckle plate 1. The third telescopic rod 502 is in the closed state, at which time the rubber ring 504 is outside the core 402.

[0056] Before installing the tee, the first telescopic rod 605 and the adjusting bend rod 607 are at their original lengths, and the magnetic plate 608 is attached to the inner wall of the head 403, and is attracted and fixed to the triangular plate 404, which is made of magnetic material. When it is necessary to clean the inner wall of the head 403, the positioning plate 604 is manually rotated to separate the positioning plate 604 from the magnetic block at the bottom. At this time, the positioning plate 604 drives the connecting belt 603 and the sliding plate 602 to rotate inside the annular frame 601, which in turn drives the protective component 609 to rotate inside the head 403. The first locking rod 6092 and the second locking rod 6094 follow the rotation of the protective component 609. The outer shell of the first locking rod 6092 begins to scrape the inner wall of the head 403, and the outer shell of the second locking rod 6094 begins to scrape the inner wall of the core 402. Impurities gradually move downwards.

[0057] After fixing the positions of the upper buckle plate 3 and the lower buckle plate 1, open the third telescopic rod 502 to the appropriate stroke according to the size of the tee. The third telescopic rod 502 drives the rubber ring 504 to move downward. At this time, the elastic rod 503 is stretched until multiple suction cups 509 are attracted and fixed to the top of the tee horizontal tube. At this time, the rubber lifting cylinder 508 is pressed on the tee to fix the position of the tee horizontal tube.

[0058] If the tee is large, the third telescopic rod 502 and the elastic rod 503 will always be at their original length, the rubber ring 504 and the lifting cylinder 508 will be in a compressed state, and most of the lifting cylinder 508 will be inside the rubber ring 504.

[0059] The rubber ring 504 is under constant compression or tension, which can easily cause it to deform and be difficult to return to its initial state. Disassemble the tee, then manually adjust the length of the adjusting column 506 to move the compression ball downwards. Repeatedly open and close the third telescopic rod 502. When the third telescopic rod 502 moves the rubber ring 504 upwards, since the adjusting column 506 and the compression ball remain stationary, the compression ball gradually enters the lifting cylinder 508 and presses it downwards, causing the lifting cylinder 508 to return to its original shape. Because the top of the rubber ring 504 is fixed by the elastic rod 503 and the third telescopic rod 502, the deformation at the top of the rubber ring 504 is small, while the bottom is stretched, promoting the return of the rubber ring 504 to its original shape. When the third telescopic rod 502 is opened to its maximum stroke, the third telescopic rod 502 drives the rubber ring 504 to move downward. The rubber ring 504, the lifting cylinder 508 and the suction cup 509 gradually contact the bottom buckle plate 1, thereby squeezing the rubber ring 504 and the lifting cylinder 508, causing them to return to their original state.

[0060] When installing the tee, open the first telescopic rod 605. The first telescopic rod 605 drives the diverter 606, adjusting rod 607, and protective component 609 upward. Manually adjust the length of the adjusting rod 607 according to the dimensions of the tee's riser section to control the position of the protective component 609 and externally fix the tee's riser section. Open multiple second telescopic rods 6098. The second telescopic rods 6098 drive the two arc-shaped plates 6096 downward. Manually adjust the adjusting rods 607 on both sides to the same length. The adjusting rods 607 drive the two semi-circular plates 6091 to the center position until the bottom arc-shaped plate 6096 is outside the tee's riser section, fixing its position. Manually connect the pipe to the threaded connection inside the tee's riser. Adjust the adjusting rod 607 again so that the three arc-shaped plates 6096 are respectively aligned with the pipe and the tee's riser section. The connection point is reinforced, at which point the bottom curved plate 6096 is under pressure.
