[0002] Welded aluminum alloy pipes are pipes used to transport gases, liquids, or solid materials. They are made of aluminum alloy and have welded seams on their surface. These pipes are typically made by welding aluminum alloy strips using a rolling machine or welding machine, resulting in welded seams on the pipe surface.

[0003] Seamless aluminum alloy pipes are lightweight, corrosion-resistant, and have excellent thermal conductivity, making them widely used in industrial, construction, and aerospace fields. They can be used to transport various media such as food, chemicals, liquids, and gases, and can also be used as structural piping.

[0004] In the use of welded aluminum alloy pipes, it is often necessary to splice them together. Currently, bolts are commonly used to connect the pipes, but this method lacks stability and affects the performance of the spliced ​​pipes during use. Therefore, an improvement is needed.

A sealing ring 6 is rotatably sleeved on the outside of the positive and negative screws 5, and the sealing ring 6 is fixedly connected to the connecting seat 1. By designing the sealing ring 6, the connection between the positive and negative screws 5 and the connecting seat 1 can be sealed.

[0022] Please see Figure 1 , Figure 2 , Figure 3 A turntable 7 is fixedly connected to the top of the positive and negative screws 5. A support seat 8 is rotatably sleeved on the outside of the turntable 7. The support seat 8 is fixedly connected to the connecting seat 1. Two symmetrically distributed connecting strips 10 are threadedly connected to the outside of the positive and negative screws 5. A guide rod 11 is slidably sleeved inside the connecting strip 10. The guide rod 11 is fixedly connected to the connecting seat 1. An inner support block 12 is fixedly connected to the outside of the connecting strip 10. The inner support block 12 contacts the inner wall of the tube body 2. A limit mechanism 9 is provided on the turntable 7.

[0023] Please see Figure 1 , Figure 2 , Figure 4The limiting mechanism 9 includes slots 91. Slots 91 are provided inside the turntable 7. Insert blocks 92 are slidably connected inside slots 91. There are multiple slots 91, arranged in a ring and evenly distributed inside the turntable 7. By designing multiple slots 91, insert blocks 92 can be inserted into slots 91 at different positions. Insert blocks 92 are slidably connected to the support base 8. A magnetic slider 93 is fixedly connected to the bottom of the insert block 92. The magnetic slider 93 is slidably connected to the support base 8, and a fixing rod is slidably sleeved inside the magnetic slider 93. 94. The fixed rod 94 is fixedly connected to the support base 8. A spring 95 is provided on the outside of the fixed rod 94. One end of the spring 95 is fixedly connected to the magnetic slider 93, and the other end of the spring 95 is fixedly connected to the support base 8. By designing the spring 95, the force of the spring 95 can be applied to the magnetic slider 93. A pull block 96 is fixedly connected to the lower end of the magnetic slider 93.

[0024] The specific implementation process of this utility model is as follows: When it is necessary to splice aluminum alloy tubes, first insert the two tube bodies 2 into the connecting seat 1 respectively, and then screw the bolt 3 into the tube body 2. At this time, the tube body 2 and the connecting seat 1 can be initially fixed. Then rotate the turntable 7, and the turntable 7 drives the positive and negative screws 5 to rotate, so that the connecting strip 10 makes a threaded movement. The two connecting strips 10 will move in opposite directions and slide along the guide rod 11. At the same time, the connecting strip 10 drives the inner support block 12 to move, so that the inner support block 12 is tightly attached to the inner wall of the tube body 2. The inner support block 12 can provide internal support for the inside of the tube body 2, which can improve the connection tightness between the tube body 2 and the connecting seat 1 and improve the splicing stability of the aluminum alloy tube.

[0025] After the splicing is completed, push the pull block 96 upward. The pull block 96 drives the magnetic slider 93 to move upward, causing the magnetic slider 93 to separate from the magnet 97. Then, under the elastic action of the compressed spring 95, the magnetic slider 93 will be given an upward counter-force. The magnetic slider 93 can drive the insertion block 92 to move upward, so that the insertion block 92 is inserted into the slot 91 inside the turntable 7. At this time, the turntable 7 can be limited, which in turn can limit the forward and reverse screws 5, and limit the connecting strip 10 and the inner support block 12, preventing the inner support block 12 from separating from the inner wall of the tube body 2. This can further improve the tightness of the connection between the tube body 2 and the connecting seat 1, and further improve the splicing stability.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
