[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5The utility model provides a technical solution: a sealed copper tube connection device, including a cylinder 1, with rubber rings 2 connected to both sides of the cylinder 1, and two pressure plates 3 symmetrically connected to the side of the rubber ring 2 away from the cylinder 1, and multiple card grooves 4 are opened on the two pressure plates 3 facing each other. The same rubber ring 5 is clamped inside every two corresponding card grooves 4, and the outer ring of the rubber ring 5 is an inclined surface. Two copper tubes 6 are symmetrically arranged inside the cylinder 1, and the ends of the copper tubes 6 away from the cylinder 1 pass through the corresponding rubber ring 5. The inner rings of the rubber rings 5 ​​fit the corresponding copper tubes 6, and a gap 7 is left between the pressure plate 3 and the corresponding copper tube 6. Nuts 8 are threadedly connected on both sides of the outer surface of the cylinder 1, and the inner ring diameter of the nut 8 is smaller than the distance between the corresponding two pressure plates 3.

[0026] During operation, one end of the copper tube 6 is passed through the rubber ring 5 and inserted into the cylinder 1, and the corresponding two pressure plates 3 are pinched to squeeze the pressure plate 3 toward the copper tube 6, driving the rubber ring 5 to press the copper tube 6. At this time, the distance between the two pressure plates 3 is reduced, and the side of the rubber ring 5 will be squeezed into the gap 7, so that the inner ring of the rubber ring 5 is fully fitted with the copper tube 6. Twist the nut 8 to move the nut 8 toward the pressure plate 3. The nut 8 will be sleeved on the outer surface of the pressure plate 3, thereby limiting and fixing the pressure plate 3, and then fixing the position of the copper tube 6. Fix the other copper tube 6 in the above manner so that the two copper tubes 6 fit together inside the cylinder 1. The limiting effect of the card slot 4 on the rubber ring 5 can ensure that the rubber ring 5 is close to the copper tube 6, ensuring the fastening effect of the copper tube 6, and the rubber ring 2 can seal the gap between the cylinder 1 and the copper tube 6.

[0027] See also Figure 1-5 The utility model provides a technical solution: a plurality of rubber sheets 9 are connected to the inner side of the pressing plate 3.

[0028] During operation, the arrangement of the rubber sheet 9 can enhance the friction between the inner side of the pressing plate 3 and the copper tube 6 , thereby facilitating the connection and fixation of the copper tube 6 .

[0029] See also Figure 1-5 The utility model provides a technical solution: sealing rings 10 are connected to both sides of the cylinder 1, and the sealing rings 10 are made of rubber.

[0030] During operation, the sealing effect of the gap between the cylinder 1 and the copper tube 6 can be improved by setting the sealing ring 10.

[0031] See also Figure 1-5 The utility model provides a technical solution: the corresponding multiple rubber rings 5 ​​are connected by a connecting rod 11.

[0032] During operation, the multiple rubber rings 5 ​​are formed into a whole by the arrangement of the connecting rod 11 , and it is not easy for a single rubber ring 5 to fall off from the slot 4 .

[0033] See also Figure 1-5The utility model provides a technical solution: an inclined surface 12 is provided on the side of the pressing plate 3 close to the cylinder 1, and the inclined surface 12 is inclined toward the interior of the cylinder 1.

[0034] During operation, due to the setting of the inclined surface 12 , when the nut 8 moves toward the pressing plate 3 , the side of the pressing plate 3 is unlikely to block the nut 8 .

[0035] See also Figure 1-5 The utility model provides a technical solution: the outer surface of the pressing plate 3 is provided with anti-slip lines.

[0036] During operation, the anti-skid pattern prevents the pressing plate 3 from slipping when being pinched.

[0037] See also Figure 1-5 , the utility model provides a technical solution: the nut 8 is made of stainless steel.

[0038] During operation, the nut 8 made of stainless steel has better strength, which is beneficial to effectively limit the pressure plate 3. At the same time, the nut 8 has better corrosion resistance, which is beneficial for the long-term use of the nut 8.

[0039] In summary, pass one end of the copper tube 6 through the rubber ring 5 and insert it into the cylinder 1, pinch the corresponding two pressure plates 3, squeeze the pressure plate 3 toward the copper tube 6, drive the rubber ring 5 to press the copper tube 6, at this time the distance between the two pressure plates 3 is reduced, the side of the rubber ring 5 will be squeezed into the gap 7, so that the inner ring of the rubber ring 5 and the copper tube 6 are fully fitted, screw the nut 8 to move the nut 8 toward the pressure plate 3, the nut 8 will be sleeved on the outer surface of the pressure plate 3, thereby limiting and fixing the pressure plate 3, and then fixing the position of the copper tube 6, and the other copper tube 6 is fixed in the above manner. The two copper tubes 6 are fixed so that they fit together inside the cylinder 1. Before the copper tubes 6 are inserted into the cylinder 1, one end of one of the copper tubes 6 can be expanded so that the other copper tube 6 can be inserted into the copper tube 6 later, which is beneficial to the connection and fixation of the two copper tubes 6. The expansion operation of the copper tube 6 is a prior art and will not be described here. The limiting effect of the card slot 4 on the rubber ring 5 can ensure that the rubber ring 5 is close to the copper tube 6, ensuring the fastening effect of the copper tube 6. The rubber ring 2 can seal the gap between the cylinder 1 and the copper tube 6.
