Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigeration parts, and more specifically to a novel connecting pipe. Background Art
[0002] In the refrigeration field of the prior art, the main pipe and multiple auxiliary pipes are generally combined by welding. In order to increase the size of the connection part, the main pipe generally adopts a flange structure. First, due to the poor ductility of the pipe, the height of the flange is limited and the processing efficiency is low. Second, the auxiliary pipe and the main pipe need to be tightly matched, the production efficiency is low, and it is impossible to position. It is not easy to control the length of the auxiliary pipe in the main pipe. If the auxiliary pipe is too long in the main pipe, it will cause noise. At the same time, the auxiliary pipe and the main pipe have a small contact area, poor sealing performance, and poor welding strength, resulting in a low yield rate and easy leakage, low production efficiency, and high cost. Utility Model Content
[0003] The purpose of the utility model is to provide a new connecting pipe with reasonable structure and low cost in view of the shortcomings of the prior art.
[0004] A new type of connecting pipe includes a main pipe and at least one auxiliary pipe. The main pipe is provided with a main hole on its circumferential surface, a transfer seat is provided in the main hole, and the auxiliary pipe is inserted in the transfer seat; a first cylinder is provided on the transfer seat, a brim is provided below the first cylinder, the brim expands the fixing area, and the brim and the main pipe are fixedly connected on the arc surface of the main pipe; a first circular hole and a second circular hole are provided in the transfer seat, and the auxiliary pipe is sleeved in the first circular hole. The utility model has a reasonable structure, and by providing the brim of the transfer seat, the contact area is expanded, the welding strength is increased, and the sealing is reliable. The main pipe is directly punched without flanging processing, which greatly improves the processing efficiency and does not cause leakage. The length of the auxiliary pipe in the main pipe is accurately controlled, and the size consistency is good.
[0005] As a further improvement and supplement to the above solution, the utility model also includes the following additional technical features:
[0006] The brim of the adapter is an arc structure, which fits the main pipe, and has a firm connection and good stability.
[0007] The adapter and the main pipe are connected by brazing or high-frequency welding. The welding connection has good stability.
[0008] The adapter seat is provided with a second cylinder below the brim, and the second cylinder extends into the main pipe, which effectively limits the position and strengthens the structure. The second cylinder extends into the main pipe with the same size, and no noise is generated.
[0009] The size of the second circular hole is smaller than that of the first circular hole, forming a step structure for easy positioning.
[0010] The second cylinder and the main hole are spaced apart to facilitate installation.
[0011] The following beneficial effects can be achieved by using the utility model: the utility model has a reasonable structure, and by setting the brim of the adapter, the contact area is expanded, the welding strength is increased, the sealing is reliable, the yield rate is greatly improved, and no leakage will be caused. The length of the auxiliary pipe in the main pipe is accurately controlled, and the size consistency is good. At the same time, the second cylinder extends into the main pipe with the same length, and no noise is generated. The main pipe is directly punched without flanging processing, which greatly improves production efficiency and reduces costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.
[0020] like Figure 1-7 As shown, the utility model is a new type of connecting pipe.
[0021] The new connecting pipe described in this embodiment includes a main pipe 1 and at least one auxiliary pipe 3. The main pipe 1 is provided with a main hole 11 on its circumferential surface, and a transfer seat 2 is provided in the main hole 11. The auxiliary pipe 3 is inserted in the transfer seat 2. The transfer seat 2 is provided with a first cylinder 21, and a brim 22 is provided below the first cylinder 21. The brim 22 extends to the outside of the first cylinder 21, which expands the fixing area with the main pipe 1, expands the contact area, increases the welding strength, and ensures reliable sealing. The brim 22 and the main pipe 1 are fixedly connected to the arc surface of the main pipe 1; the transfer seat 2 is provided with a first circular hole 24 and a second circular hole 25, and the auxiliary pipe 3 is sleeved in the first circular hole 24.
[0022] Furthermore, the brim portion 22 on the adapter 2 is an arc structure, which fits the main pipe 1 , and the arc size of the brim portion 22 matches that of the main pipe 1 .
[0023] Furthermore, the adapter 2 and the main pipe 1 are connected by brazing or high-frequency welding.
[0024] Furthermore, the adapter 2 is provided with a second cylinder 23 below the brim 22, and the second cylinder 23 extends into the main pipe 1, thereby providing position limiting and structural reinforcement.
[0025] Furthermore, the size of the second circular hole 25 is smaller than that of the first circular hole 24 , forming a step structure, thereby effectively positioning the auxiliary pipe 3 .
[0026] Furthermore, a gap is set between the second cylinder 23 and the main hole 11, which is convenient for installation.
[0027] When the new connecting pipe is used, the number of main holes 11 of the main pipe 1 is set according to the needs of the connecting pipeline, and then the adapter 2 is welded, and then the auxiliary pipe 3 is welded.
[0028] The above are preferred implementations of the present invention, which do not limit the protection scope of the present invention. Any modifications and improvements made by those skilled in the art based on the design ideas of the present invention should be regarded as within the protection scope of the present invention.
