[0019] The utility model is described in detail below in combination with the drawings and examples.

[0020] A three-face sealing groove aluminum alloy profile, like Figure 1 And Figure 2As shown, it comprises a profile body 1, long grooves are arranged on four side walls of the profile body 1, and closing faces for closing the long grooves are further arranged on three side walls of the profile body 1, recesses are arranged at two ends of the closing faces, and bending portions 2 are arranged on mutually opposite inner walls of the two recesses and are bent towards the long grooves, the bending portions 2 are used for abutting against one end of the key strip 7, and the bending portions 2 can be elastically deformed after being abutted against by the key strip 7, the recesses are formed by cutting on the closing faces, the two ends of the key strip 7 can enter the recesses of the two profile bodies 1 respectively by arranging the recesses at the two ends of the closing faces, the fixing of the key strip 7 is completed by tightening the fixing screws 8 on the key strip 7, the four faces of the profile body 1 can all be provided with the key strip 7 due to the arrangement of the recesses, so that the connecting strength between the two adjacent profile bodies 1 is ensured, the length of the recesses is not easy to control during the cutting process, and generally cannot be less than half of the key strip 7, so generally it is greater than half of the key strip 7, so that there is a large gap between the two ends of the key strip 7 and the closing face after the key strip 7 is fixed, the bending portions 2 can be bent to a certain extent, so that the key strip 7 can be placed, and the outer side face of the bending portion 2 abuts against one end of the key strip 7 after the key strip 7 is installed, so that the gap around the key strip 7 is small, which helps to reduce the entry of dust.

[0021] As shown in Figure 2 and Figure 3 the bending portions 2 are integrally formed with the closing faces, the bending portions 2 are formed by cutting, and the movable ends of the bending portions 2 are bent downwards, and the fixed ends of the bending portions 2 are integrally formed with the closing faces, so that the bending portions 2 are convenient to manufacture and the connecting strength of the bending portions 2 is ensured, and the closing face is provided with two positioning strips 3 on the side facing the long grooves, the distance between the two positioning strips 3 is equal to the width of the bending portions 2, and people can cut along the side where the two positioning strips 3 are close to each other during the cutting process of the recesses, so that the cutting of the recesses is facilitated, and the two ends of the positioning strips 3 extend to the two ends of the profile body 1, and the arrangement of the positioning strips 3 improves the strength of the closing face and the strength of the profile body 1, and the profile body 1 is coated with an aluminum oxide coating, the aluminum oxide coating has a certain corrosion resistance, and the overall service life of the profile body 1 is ensured.
