Aluminum profile

The invention discloses aluminum profile. The cross section of the aluminum profile comprises two sleeved circular ring structures; first clamp pieces are arranged along the tangential direction of the large circular ring, second clamp pieces extending out of the large circular ring are arranged along the tangential direction of the small circular ring, and the first clamp pieces are parallel to the second clamp pieces; there are two groups of parallel first clamp pieces and second clamp pieces, one group directly forms a first clamp part, and the first clamp piece and second clamp piece of the other group bend towards the lower sides and extend to form a second clamp part. The cross section of the aluminum profile comprises two sleeved circular ring structures, the circular ring structures are used as the body structure of the profile, and the clamp pieces are arranged in the tangential directions thereof to form the external connecting clamp parts. The aluminum profile is ingenious in structure, convenient to match with the other connecting pieces and firm in combination; by means of the hollow structure, the profile is light in weight, and material is saved.
