It can be divided into gas pipe and liquid pipe. When installing the manifold, it is necessary to use the pipe connection structure to assist the connection of the pipeline.

[0003] In the prior art, for example, Chinese patent CN214699699U discloses a pipe connection structure of an air-conditioning diversion pipe, including a main pipe and multiple diversion pipes, the pipe connection structure also includes a connecting pipe, one end of the connecting pipe is provided with a main flow port connected to the main pipe, and the other end is provided with a diversion port connected to the diversion pipe, the main pipe and the main flow port are welded, one end of the main pipe and the diversion pipe is connected to the connecting pipe, and the other end is used to be connected to an external pipe fitting, a groove is provided on the pipe wall of one end of the main pipe and / or the diversion pipe connected to the external pipe fitting, a tin ring is provided in the groove, and the external pipe fitting is sleeved with the main pipe or the diversion pipe.

[0004] In the above patent, although the problem that workers need separate welding tools to assist in pipe welding is solved by connecting pipes and tin rings, the diversion pipe is usually made of copper. When the flow rate of the medium in the pipe is too fast, the liquid medium collides with the inner wall of the bend of the pipe, causing the pipe to vibrate, thereby increasing the noise when the pipe is in use. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the shunt pipe in the prior art is usually made of copper. When the flow rate of the medium in the pipe is too fast, the liquid medium collides with the inner wall of the bend of the pipe, causing the vibration of the pipe, thereby increasing the noise when the pipe is used. A pipe connection structure for an air-conditioning shunt pipe is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pipe connection structure of an air-conditioning shunt pipe, comprising a main pipe, one end of the main pipe is fixedly connected to branch pipe one and branch pipe two, the other end of the main pipe is fixedly connected to a valve, one end of the valve is fixedly connected to an auxiliary pipe, the outer ring surface of the auxiliary pipe is connected to an extension pipe by a thread, and one side of branch pipe one and branch pipe two is clamped with a protective block, the inner wall of the protective block is installed with a noise reduction filling block, the bottom of the protective block is fixedly connected to an arc block, and one side of the arc block is clamped and connected to the main pipe.

[0012] Preferably, a fixing ring is engaged on one side of the reinforcement pipe, and the outer ring surface of the fixing ring is fixedly connected to an inner wall of the branch pipe.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, the arc block can be used to assist the installation of the protective block on one side of the main pipe. When the protective block is installed, one side of the limit ring overlaps the protective block to limit the installation position of the protective block. After the protective block is installed, the noise reduction filling block can be used to wrap the bending part of the pipe fitting.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example

[0023] Reference Figure 1-4 As shown: a pipe connection structure of an air-conditioning shunt pipe, including a main pipe 3, one end of the main pipe 3 is fixedly connected with a branch pipe 1 and a branch pipe 2 7, the other end of the main pipe 3 is fixedly connected with a valve 5, one end of the valve 5 is fixedly connected with an auxiliary pipe 17, the outer ring surface of the auxiliary pipe 17 is connected with an extension pipe 4 through a thread, and a protective block 2 is clamped on one side of the branch pipe 1 and the branch pipe 2 7, a noise reduction filling block 16 is installed on the inner wall of the protective block 2, an arc block 6 is fixedly connected to the bottom of the protective block 2, and one side of the arc block 6 is clamped and connected with the main pipe 3.

[0024] A limiting ring 11 is overlapped on the top of the protection block 2, and the inner wall of the limiting ring 11 is fixedly connected to the outer ring surface of the branch pipe 1.

[0025] A support block 10 is fixedly connected to one side of the protection block 2, and the top of the support block 10 overlaps with the branch pipe 2 7.

[0026] A sealing ring 2 9 is fixedly connected to the inner wall of the extension tube 4 , a sealing ring 1 8 is arranged on one side of the sealing ring 2 9 , and one side of the sealing ring 1 8 is fixedly connected to the auxiliary tube 17 , and a thread is provided on the inner wall of the auxiliary tube 17 .

[0027] The branch pipe 1 and the branch pipe 2 7 can be used to divert the liquid passing through the main pipe 3. The valve 5 connects the main pipe 3 and the auxiliary pipe 17 to facilitate the adjustment of the liquid flow through the inside of the main pipe 3, thereby preliminarily reducing the noise inside the pipe fitting. The protective block 2 is installed on both sides of the branch pipe 1 and the branch pipe 2 7. The noise reduction filling block 16 installed inside the protective block 2 can absorb the noise of the liquid flowing through the bending parts of the branch pipe 1 and the branch pipe 2 7, thereby reducing the noise of the entire pipe fitting when in use. The limit ring 11 on the top of the protective block 2 can limit the installation range of the protective block 2. The supporting blocks 10 are engaged with each other. The overlap of the supporting block 10 and the branch pipe 2 7 is used to support one side of the branch pipe 2 7, thereby improving the stability of the installation of the protective block 2. The engagement of the arc block 6 with the outer annular surface of the main pipe 3 can assist the installation and disassembly of the two protective blocks 2. Example

[0028] like Figure 1 - Figure 4 As shown, the inner walls of the branch pipe 1 and the branch pipe 2 7 are both fixedly connected with elastic blocks 12, and one side of the elastic blocks 12 is arc-shaped.

[0029] The inner walls of the branch pipe 1 and the branch pipe 2 7 are both fixedly connected with an inner ring 13 , and one side of the inner ring 13 is fixedly connected with a reinforcement pipe 14 .

[0030] A fixing ring 15 is clamped on one side of the reinforcement pipe 14, and the outer ring surface of the fixing ring 15 is fixedly connected to the inner wall of the branch pipe 1.

[0031] By using the elastic block 12 inside the branch pipe 1 and the branch pipe 2 7, the connecting pipe installed inside the branch pipe 1 and the branch pipe 2 7 can be limited. The built-in ring 13 is installed in the branch pipe 1 and the branch pipe 2 7. One side of the built-in ring 13 overlaps with the end face of the connecting pipe, which can limit the insertion depth of the connecting pipe inside the branch pipe 1 and the branch pipe 2 7.

[0032] The method of use and working principle of the device: First, the branch pipe 1, the branch pipe 2 7 and the main pipe 3 form the main body of the air-conditioning shunt pipe, and the two protective blocks 2 are installed on one side of the limiting ring 11, and the one side of the arc block 6 is engaged with the side wall of the main pipe 3. At this time, the two protective blocks 2 are engaged with each other, and the two limiting rings 11 are engaged. The noise reduction filling block 16 inside the protective block 2 is wrapped around the branch pipe 1, the branch pipe 2 7 and the main pipe 3. The noise reduction filling block 16 is made of foam and can absorb the energy of noise waves, thereby reducing the reflection and propagation of sound. When the entire pipe fitting is connected, the extension pipe 4 is rotated outside the auxiliary pipe 17 to adjust the overlapping length of the extension pipe 4 and the auxiliary pipe 17, thereby changing the entire pipe fitting. The length of use is determined by passing one of the connecting pipes through the sealing ring 2 9 and the sealing ring 1 8 in sequence and entering the auxiliary pipe 17 to realize the connection of one end of the pipe fitting. When the branch pipe 1 and the branch pipe 2 7 are connected to the connecting pipe, the connecting pipe is inserted into the branch pipe 1 until the end of the connecting pipe overlaps with the built-in ring 13. At this time, the connecting pipe is installed in place, and the elastic block 12 pressurizes the side wall of the connecting pipe to reduce the loosening of the connecting pipe to complete the installation of the connecting pipe. During the use of the entire pipe fitting, the valve 5 can be used to adjust the flow rate of the medium inside the pipe fitting. The noise generated when the liquid medium enters the branch pipe 1 and the branch pipe 2 7 through the bend can be absorbed by the noise reduction filling block 16, thereby reducing the noise of the entire pipe fitting when in use.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
