[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5 The utility model provides a technical solution: a low-resistance flow-dividing three-way pipe joint for ventilation and air conditioning ducts, comprising a three-way pipe body 10, a sleeve 20, a connecting rod 201, a connecting plate 1 202, an air bag 1 203, an air bag 204, a pipe 205, a connecting plate 206, a ring 30, a support frame 301, a column 302 and a support plate 303;

[0031] The low resistance flow dividing three-way pipe joint increases the sealing type between the ventilation pipe and the ventilation pipe. The specific implementation method is as follows:

[0032] The interior of the tee pipe body 10 is set as a hollow structure, and the surface of the tee pipe body 10 is sleeved with a sleeve 20; the surface of the tee pipe body 10 is provided with a sealing mechanism, and the sealing mechanism includes: the surface of the sleeve 20 is fixedly connected with a connecting plate 206, and the end of the connecting plate 206 is fixedly connected with a connecting rod 201, and the end of the connecting rod 201 is fixedly connected with a connecting plate 1 202, the surface of the sleeve 20 is sleeved with an airbag 1 203, the end of the tee pipe body 10 is fixedly connected with an airbag 204, and the airbag 204 is connected to the surface with a pipe 205, and the end of the pipe 205 penetrates the tee pipe body The body 10 is inserted into the interior of the airbag 1 203, the surface of the tee body 10 is provided with a thread, and the inner wall of the sleeve 20 is embedded with a thread, and the sleeve 20 and the tee body 10 are threadedly connected, and one side of the sleeve 20 is arranged at the end of the tee body 10, the end of the airbag 204 is in contact with the surface of the connecting plate 1 202, and the connecting plate 1 202 is sleeved and installed on the surface of the tee body 10, the tee body 10 and the connecting plate 1 202 are slidably connected, the inner walls of the connecting plate 206 are in contact with the surface of the tee body 10, and the tee body 10 and the connecting plate 206 are slidably connected.

[0033] Insert one side of the ventilation pipe into the sleeve 20, so that the end of the ventilation pipe fits with the end of the airbag 204. Rotate the sleeve 20, which is provided with threads inside. The sleeve 20 rotates along the threads on the surface of the tee pipe body 10. The sleeve 20 rotates along the threads on the surface of the ventilation pipe. At this time, the end of the sleeve 20 rotates to the surface of the ventilation pipe. The sleeve 20 moves to drive the connecting plate 206 to move, so that the connecting plate 206 moves outward on the surface of the tee pipe body 10. The connecting plate 20 6 drives the connecting rod 201 to move, and the connecting rod 201 drives the connecting plate 1 202 to move, so that the connecting plate 1 202 moves on the surface of the three-way pipe body 10. At this time, the connecting plate 1 202 squeezes the airbag 1 203, so that the airbag 1 203 shrinks, and the gas inside the airbag 1 203 enters the inside of the pipe 205, and enters the inside of the airbag 2 204 through the pipe 205, so that the airbag 2 204 expands, and the airbag 2 204 expands between the three-way pipe body 10 and the ventilation pipe to block the gap between the two.

[0034] The low-resistance flow-dividing three-way pipe joint is convenient for supporting the ventilation pipe. The specific implementation method is as follows:

[0035] A supporting mechanism is provided on the surface of the tee pipe body 10, and the supporting mechanism includes: a circular ring 30 is fixedly connected to the opening of the tee pipe body 10, and a supporting frame 301 is fixedly connected to the surface of the circular ring 30, a column 302 is fixedly connected to the surface of the supporting frame 301, and a supporting plate 303 is fixedly connected to the end of the column 302, the circular ring 30 is provided at the opening of the tee pipe body 10, and the middle of the circular ring 30 is through-connected, the diameter of the circular ring 30 is smaller than the internal diameter of the tee pipe body 10, the supporting plate 303 is provided on the outside of the tee pipe body 10, and the supporting plate 303 is provided on the outside of the sleeve 20.

[0036] When one side of the ventilation pipe is inserted into the interior of the sleeve 20, the end of the support plate 303 slides along the inner wall of the ventilation pipe, so that the support plate 303 moves to the opening of the ventilation pipe, and the support plate 303 supports the inner wall of the ventilation pipe, which can increase the stability of the ventilation pipe. When the ventilation pipe is hit, the support plate 303 can support the pipe wall of the ventilation pipe to prevent the ventilation pipe from being damaged and bent, and increase the stability of the connection between the ventilation pipe and the three-way pipe body 10. When the air enters the interior of the three-way pipe body 10 through the ventilation pipe, the air enters the interior of the ring 30 through the ventilation pipe. At this time, due to the small diameter of the ring 30, the resistance to the air can be reduced, so that the flow rate of the air out of the ring 30 is increased, and the air enters the interior of the three-way pipe body 10 through the ring 30.

[0037] Working principle: When using the low-resistance diversion three-way pipe joint of the ventilation and air-conditioning duct, a sleeve 20, air bag 1 203 and air bag 2 204 are set to increase the sealing type between the ventilation pipe, and a support frame 301, a column 302 and a support plate 303 are set to facilitate the support of the ventilation pipe, thereby increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
