When the high water pressure flow in the main pipe directly collides with the inner surface of the branch pipe vertically during use, the branch pipe is subjected to a large pressure in an instant, and is prone to damage after long-term use. The impact resistance is insufficient, the service life of the tee pipe is reduced, and more convenience cannot be brought to the workers. UTILITY MODEL CONTENT

[0009] Two pressure relief plates are rotatably installed at the two ends of the buffer plate, and two pressure relief assemblies are arranged between each pressure relief plate and the buffer plate.

[0010] The pressure relief assembly comprises a first rotating frame rotatably installed at the bottom of the pressure relief plate, a transition block rotatably installed at the other end of the first rotating frame, a door-shaped rod slidably penetrating the end of the transition block, and a second rotating frame rotatably installed on the surface of the transition block.

[0011] A connecting plate is rotatably installed at the end of each second rotating frame away from the corresponding transition block, and a spring is connected between the bottom of the connecting plate and the inner bottom of the branch pipe.

[0012] Preferably, notches are formed at the two ends of the buffer plate and the end of each pressure relief plate close to the buffer plate, a rotating shaft is movably penetrated in each notch, and a connecting block is sleeved between two rotating shafts on the same side.

[0013] Preferably, both ends of each rotating shaft are slidingly connected to the inner surface of the branch pipe, and a sliding groove is formed on the front and back sides of the branch pipe, and the sliding groove is slidingly connected to the corresponding rotating shaft.

[0014] Preferably, both ends of the connecting plate are slidingly attached to the inner surface of the branch pipe.

[0015] Preferably, both ends of the branch pipe and the end of the main pipe away from the branch pipe are provided with threaded openings.

[0016] Compared with the prior art, the high-strength impact-resistant tee pipe structure has the advantages that:

[0017] The high water pressure flow in the main pipe is preferentially collided with the buffer plate, so that the buffer plate moves downward and the angle between the buffer plate and the pressure relief plate is opened, at this time, under the action of the pressure relief plate, the first rotating frame, the transition block, the second rotating frame, the connecting plate and the spring, the trend of the angle between the pressure relief plate and the buffer plate is suppressed, so that the buffer plate has a certain pressure relief effect on the high water pressure flow in the main pipe, and at the same time when the pressure relief plate is opened, the water flow also has a trend of changing from the vertical direction to the horizontal direction and contacting the branch pipe, further reducing the impact of the high water pressure flow on the inner wall of the branch pipe, thereby having a certain high-strength impact resistance.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0023] REFERENCE Figs. 1 to 3The utility model discloses a high-strength impact-resistant tee pipe structure which comprises the following parts:

[0024] The branch pipe 1 and the main pipe 2 are fixedly connected at the top of the middle section of the branch pipe 1, and the two ends of the branch pipe 1 and the end of the main pipe 2, which is away from the branch pipe 1, are provided with threaded openings 15, so that the branch pipe 1 and the main pipe 2 are connected with external water pipes.

[0025] The buffer plate 3 is slidably connected in the branch pipe 1 and is arranged below the main pipe 2, the two pressure relief plates 4 are rotatably arranged at the two ends of the buffer plate 3, notches 11 are formed in the two ends of the buffer plate 3 and the end of each pressure relief plate 4, which is close to the buffer plate 3, rotating shafts 12 are movably arranged in each notch 11, connecting blocks 13 are jointly sleeved between each two rotating shafts 12, which are located on the same side, and the two ends of each rotating shaft 12 are slidably connected to the inner surface of the branch pipe 1, and sliding grooves 14 are formed in the front and back sides of the branch pipe 1 and are slidably connected with the corresponding rotating shafts 12, so as to limit the buffer plate 3 and prevent the buffer plate 3 from being deflected in the branch pipe 1.

[0026] Two pressure relief assemblies are arranged between each pressure relief plate 4 and the buffer plate 3, the pressure relief assembly comprises a first rotating frame 5, which is rotatably arranged at the bottom of the pressure relief plate 4, a transition block 6 is rotatably arranged at the other end of the first rotating frame 5, a door-shaped rod 7 is slidably arranged at the end of the transition block 6, the door-shaped rod 7 is fixedly arranged at the inner bottom of the branch pipe 1, and a second rotating frame 8 is rotatably arranged on the surface of the transition block 6, one end of each second rotating frame 8, which is away from the corresponding transition block 6, is rotatably arranged with a connecting plate 9, the front and back ends of the connecting plate 9 are slidably arranged on the inner surface of the branch pipe 1, so as to ensure the stability of the connecting plate 9 when sliding up and down, and a spring 10 is jointly arranged between the bottom of the connecting plate 9 and the inner bottom of the branch pipe 1.

[0027] The working principle of the utility model is as follows:

[0028] When the high water pressure water flow enters into the branch pipe 1 from the main pipe 2, the water flow directly impacts the buffer plate 3 and then pushes it to move downward, so that the high water pressure water flow can not directly impact the inner wall of the branch pipe 1, and at the same time, when the buffer plate 3 moves downward, the two pressure relief plates 4 are pulled to move downward through the rotating shaft 12 and the connecting block 13, but because the other end of the pressure relief plate 4 is in contact with the inner bottom wall of the branch pipe 1, when the pressure relief plate 4 is stressed, the angle between the bottom of the pressure relief plate 4 and the buffer plate 3 is enlarged, so that the pressure relief plate 4 presses the first rotating frame 5, pulls the transition block 6 on the corresponding door-shaped rod 7 to move towards the direction close to the pressure relief plate 4, at this time, the transition block 6 pulls the connecting plate 9 to move downward through the second rotating frame 8, and the spring 10 is pressed, so that the spring 10 is deformed, so that the connecting plate 9 can be inhibited from moving downward under the deformation force of the spring 10, so that the second rotating frame 8, the transition block 6 and the first rotating frame 5 are inhibited from opening the angle between the pressure relief plate 4 and the buffer plate 3, so that the buffer plate 3 has a certain pressure relief effect on the high water pressure water flow in the main pipe 2, and when the pressure relief plate 4 is opened, the angle of the water flow flowing along the surface of the pressure relief plate 4 is also reduced, so that the water flow entering into the branch pipe 1 can be in contact with the branch pipe 1 from the vertical direction to the horizontal direction, further reducing the impact of the high water pressure water flow on the inner wall of the branch pipe 1, so as to have a certain high impact resistance.

[0029] Further, the fixed connection should be understood in a broad sense unless otherwise specified and limited, for example, it can be welding, gluing, or integrally formed with other conventional means familiar to those skilled in the art.

[0030] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
