DETAILED DESCRIPTION

[0020] The following is a combination of the appended examples of the present invention Figure 1-4 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] As shown in the figure, an aluminum tube that is easy to splice and install includes a first tube section 1 and a second tube section 2. A splicing piece 3 made of elastic metal is provided on the inner wall of the first tube section 1. The splicing piece 3 has a plurality of splicing arms 31 in a circular array along the axis of the first tube section 1. One end of the splicing arm 31 is fixedly connected to the inner wall of the first tube section 1, and the other end extends out of the first tube section 1 along the inner wall of the first tube section 1. A splicing protrusion 32 is formed on the outer side surface of the end of the splicing arm 31 extending out of the first tube section 1, and a splicing annular groove 21 matching the splicing protrusion 32 is provided on the inner wall of the second tube section 2. When the first tube section 1 and the second tube section 2 are spliced, the splicing arm 31 extends into the second tube section 2 so that the splicing protrusion 32 is stuck in the splicing annular groove 21.

[0022] Specifically, the end of the splicing arm 31 is fixedly connected to the structure on the inner wall of the first pipe section 1: a mounting ring groove 11 is opened on the inner wall of the first pipe section 1, and a mounting protrusion 33 matching the mounting ring groove 11 is formed on the outer side surface of the end of the splicing arm 31 located in the first pipe section 1, and a first support arm 34 inclined to the axis of the first pipe section 1 is formed on the inner side surface of the end of the splicing arm 31 located in the first pipe section 1. The ends of several first support arms 34 away from the splicing arm 31 are integrally connected, and the mounting protrusion 33 is snapped into the mounting ring groove 11 under the action of the first support arm 34, so as to realize the fixed connection between the splicing arm 31 and the inner wall of the first pipe section 1. Then, through the above structure, when the splicing piece 3 is fixedly connected to the inner wall of the first pipe section 1, the end of the splicing arm 31 with the mounting protrusion 33 is pressed inward, so that the first support arm 34 is elastically deformed and the end of the splicing arm 31 drives the mounting protrusion 33 to swing inward, so that several mounting protrusions 33 can extend into the first pipe section 1 along with the splicing arm 31. Then, the splicing piece 3 is slid inward on the inner wall of the first pipe section 1. When the mounting protrusion 33 slides to the mounting ring groove 11, the first support arm 34 is reset and drives the splicing arm 31 and then drives the mounting protrusion 33 to be stuck in the mounting ring groove 11, thereby achieving a fixed connection between the splicing arm 31 and the inner wall of the first pipe section 1.

[0023] In the above embodiment, when the first pipe section 1 and the second pipe section 2 are spliced and installed, the port of the second pipe section 2 is aligned with the end of the splicing arm 31 extending out of the first pipe section 1, and the second pipe section 2 is pushed toward the first pipe section 1. The end of the splicing arm 31 is elastically deformed and swings inward under the action of the inner wall of the second pipe section 2, so that the splicing protrusion 32 extends into the second pipe section 2 and the splicing protrusion 32 slides on the inner wall of the second pipe section 2 as the second pipe section 2 is pushed. When the second pipe section 2 is pushed until its end is connected with the end of the first pipe section 1, the splicing protrusion 32 slides on the inner wall of the second pipe section 2 to the splicing ring groove 21. The splicing protrusion 32 is stuck in the splicing ring groove 21 under the resetting action of the splicing arm 31, and the end of the splicing arm 31 is fixed by the matching disc of the splicing protrusion 32 and the splicing ring groove 21. The first and second pipe sections 1 and 2 are fixedly connected to the inner wall of the second pipe section 2, thereby realizing the splicing and installation of the first pipe section 1 and the second pipe section 2. The splicing process of the above-mentioned first pipe section 1 and the second pipe section 2 is very convenient to operate. It is only necessary to align the second pipe section 2 with the end of the splicing arm 31 and push it. After the first pipe section 1 and the second pipe section 2 are spliced, the formed spliced pipe section has a neat and beautiful appearance and will not interfere with the pipe layout of the aluminum tube. The fixed connection between the splicing arm 31 and the inner wall of the first pipe section 1 achieved by the cooperation of the mounting protrusion 33 and the mounting ring groove 11 allows the splicing piece 3 to be processed and formed separately. For the first pipe section 1 and the second pipe section 2 that need to be spliced, it is only necessary to form the mounting ring groove 11 and the splicing ring groove 21, which reduces the difficulty of reprocessing the aluminum tube after forming and reduces the production cost of the manufacturer.

[0024] Preferably, a second support arm 35 inclined toward the axis of the second pipe segment 2 is formed on the inner side surface of the end of the splicing arm 31 extending into the second pipe segment 2, and a plurality of the second support arms 35 are integrally connected at the ends away from the splicing arm 31. The second support arm 35 will elastically deform together with the splicing arm 31 during the process of the splicing protrusion 32 being snapped into the splicing ring groove 21. After the splicing protrusion 32 is snapped into the splicing ring groove 21, it supports the splicing arm 31 and then the splicing protrusion 32, thereby strengthening the connection strength between the splicing arm 31 and the second pipe after the splicing protrusion 32 is snapped into the splicing ring groove 21, thereby strengthening the connection strength between the splicing arm 31 and the second pipe after the splicing protrusion 32 is snapped into the splicing ring groove 21, thereby strengthening the connection strength after the first pipe segment 1 and the second pipe segment 2 are spliced and installed.

[0025] Preferably, the cross-section of the splicing protrusion 32 is a trench-shaped type, so that when the first pipe section 1 and the second pipe section 2 are spliced and installed, the splicing protrusion 32 can more easily extend into the second pipe section 2, further facilitating the splicing and installation operation of the first pipe section 1 and the second pipe section 2.

[0026] Preferably, the splicing piece 3 is made of beryllium copper alloy. Based on the corrosion resistance and high strength characteristics of beryllium copper alloy, the connection strength and durability of the first pipe section 1 and the second pipe section 2 after splicing and installation through the splicing piece 3 are guaranteed.

[0027] Furthermore, a plug-in step 12 is provided on the end of the first pipe section 1 facing the second pipe section 2, and a plug-in portion 22 matching the splicing step is formed on the end of the second pipe section 2 facing the first pipe section 1. The plug-in portion 22 is inserted into the plug-in step 12 so that the outer wall of the plug-in portion 22 is in contact with the side wall of the splicing step.

[0028] In the above preferred embodiment, the cooperation between the plug-in portion 22 and the plug-in step 12 enhances the radial bending resistance of the first pipe segment 1 and the second pipe segment 2 after splicing and installation, thereby enhancing the connection strength of the first pipe segment 1 and the second pipe segment 2 after splicing and installation.

[0029] Preferably, a first sealing ring groove 13 is provided on the side wall of the plug-in step 12, and a second sealing ring groove 23 aligned with the first sealing ring groove 13 is provided on the outer wall of the plug-in portion 22. Sealing rings 4 are provided in the first sealing ring groove 13 and the second sealing ring groove 23, and the sealing performance of the first pipe section 1 and the second pipe section 2 after splicing and installation is enhanced by the action of the sealing ring 4.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
