In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a metal pipe fitting structure convenient for bonding, which comprises a first metal pipe, a second metal pipe and a rubber ring; the first metal pipe and the second metal pipe are fixedly bonded through an adhesive; the left side and the right side of the outer side of the opening of the second metal pipe are pressed into concave platforms; the rubber ring is sleeved on the second metal pipe; the radius of the first metal pipe is larger than that of the second metal pipe.

Further, the length of the concave table is 5-15 mm; the depth of the concave stage is 1/2 times the radius of the second metal tube.

Further, the radius of the inner ring of the rubber ring is 1/2-1 times of the radius of the second metal pipe; the radius of the outer ring of the rubber ring is 2 times of that of the inner ring.

Further, the adhesive is cyanoacrylate.

Furthermore, the first metal pipe and the second metal pipe are made of copper, aluminum or alloy.

The utility model discloses following beneficial effect has:

1. the utility model discloses it is poor to current tubular metal resonator accessory welding quality uniformity, unstable problem has set up new tubular metal resonator accessory structure and new bonding mode and has replaced the welding mode, improves work efficiency, reduction in production cost.

2. The utility model discloses a rubber circle inner circle radius is 1/2-1 times of second tubular metal resonator radius, and rubber circle outer lane radius is 2 times of inner circle radius, and such size setting can prevent that the gluing agent from spilling over at the metal accessories edge, can prevent unedged production simultaneously, promotes the whole quality of accessory.

3. The utility model discloses press the opening part of second tubular metal resonator into the concave station, increased the area of contact of gluing agent with the second tubular metal resonator, increase the horizontal power between the metal layer simultaneously, great improvement bond strength.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
