[0002] Aluminum tubes are hollow metal tubes made from pure aluminum or aluminum alloys through extrusion processing. They belong to the category of non-ferrous metal tubes. Their product forms include square tubes, round tubes, and patterned tubes. According to the processing method, they can be divided into seamless aluminum tubes and ordinary extruded tubes. According to the precision, they can be divided into ordinary type and precision type that requires secondary processing.

[0003] In the existing technology, when it is necessary to connect two sets of aluminum tube connectors, a connecting tube is used in conjunction with crimping pliers. First, the two sets of aluminum tube connectors are inserted into both ends of the connecting tube, and then the crimping pliers can be used to press and fix the connecting tube, thus making it easy to connect the two sets of aluminum tube connectors.

[0004] However, after being pressed and fixed with clamping pliers, the aluminum tube may vibrate due to internal water flow during long-term use, which may cause the connection between the aluminum tube joint and the connecting pipe to loosen due to vibration, and may lead to leakage at the aluminum tube connection. To address this issue, this utility model proposes a clamping aluminum tube joint to solve the above-mentioned technical problems. Utility Model Content

[0007] The pressing plate is connected to the positioning plate by a hinge. Both the positioning plate and the pressing plate are provided with fixing plates on their sides. The surface of the fixing plate is provided with threaded holes, and positioning bolts are screwed into the threaded holes. A set of fixing plates is provided with a moving groove on its side.

[0008] Furthermore, a sealing gasket is provided inside the connecting groove, and the sealing gasket has an overall annular plate structure.

[0009] Furthermore, a sealing strip is provided on the inner side of the connecting pipe.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example 1

[0025] This utility model provides, for example Figures 1-6 As shown, a press-fit aluminum tube connector includes: a connecting tube 1, with connecting grooves 2 on both ends of the connecting tube 1, into which a first aluminum tube connector 3 and a second aluminum tube connector 4 are respectively inserted; a pressing plate 5, with a positioning plate 7 connected to the pressing plate 5 by a hinge 6; fixing plates 8 are provided on the sides of both the positioning plate 7 and the pressing plate 5; threaded holes are provided on the surface of the fixing plates 8, with positioning bolts 9 screwed into the threaded holes; and a set of moving grooves 10 are provided on the sides of the fixing plates 8.

[0026] First, insert the first aluminum tube connector 3 and the second aluminum tube connector 4 into the two ends of the connecting tube 1 respectively. Then, use crimping pliers to press and seal the connecting tube 1. Next, put the pressing plate 5 and the positioning plate 7 on the connecting tube 1. Then, screw the positioning bolt 9 to make the pressing plate 5 and the positioning plate 7 clamp the surface of the connecting tube 1, thereby increasing the stability of the connecting tube 1 and avoiding subsequent leakage problems.

[0027] Example 2: Figure 1 and Figure 2 As shown, a connecting pipe 1 is provided to facilitate the connection of the first aluminum pipe joint 3 and the second aluminum pipe joint 4. A sealing gasket 11 is provided in the connecting groove 2. The sealing gasket 11 has an overall annular plate structure. A sealing strip 12 is provided on the inner side of the connecting pipe 1.

[0028] More specifically, during use, the first aluminum tube connector 3 and the second aluminum tube connector 4 are first inserted into the connecting groove 2. Then, the connecting tube 1 can be pressed with crimping pliers, thereby connecting and sealing the first aluminum tube connector 3 and the second aluminum tube connector 4 through the connecting tube 1. The sealing strip 12 and the sealing gasket 11 can further enhance the connection and sealing between the first aluminum tube connector 3, the second aluminum tube connector 4 and the connecting tube 1.

[0029] Example 3: Figures 3-6As shown, in order to further improve the stability after the fixing of the connecting pipe 1, a pressing plate 5 and a positioning plate 7 are provided. Support plates 13 are provided on the sides of the pressing plate 5 and the positioning plate 7. A limiting frame 14 is provided on the end face of the support plate 13. A traction rod 15 is provided on the end face of the moving groove 10. A limiting spring 16 and a limiting plate 17 are sleeved on the surface of the traction rod 15. The limiting plate 17 is slidably connected to the moving groove 10. The limiting plate 17 is integrally in the shape of a "C"-shaped plate. One end of the limiting spring 16 is fixedly connected to the end face of the moving groove 10, and the other end of the limiting spring 16 is fixedly connected to the side of the limiting plate 17;

[0030] More specifically, in use, first, the positioning plate 7 and the pressing plate 5 can be sleeved on the connecting pipe 1 by using the cooperation of the hinge 6, and then the pressing plate 5 and the positioning plate 7 are connected by using the positioning bolt 9, so that the pressing plate 5 and the positioning plate 7 can press the connecting pipe 1. Then, the limiting plate 17 is used to limit the upper part of the positioning bolt 9, so as to prevent the positioning bolt 9 from disengaging from the fixing plate 8. The limiting spring 16 cooperates with the traction rod 15 to facilitate the displacement of the limiting plate 17 on the one hand and facilitate the automatic reset of the limiting plate 17 after being pulled on the other hand. The limiting frame 14 is sleeved on the protruding part of the connecting pipe 1 to prevent the pressing plate 5 and the positioning plate 7 from sliding on the connecting pipe 1.
