DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] A connection structure of a frame profile, comprising two profiles 1 and a connector for fixedly connecting the two profiles 1, wherein the material of the profiles 1 includes but is not limited to aluminum alloy, and the two profiles 1 are fixedly connected together by the connector, wherein the connector includes a plug-in component 3 and locking structures arranged at both ends of the plug-in component 3, and the profile 1 has a slot 2 matching the plug-in component 3, and the two ends of the plug-in component 3 are respectively inserted into the slots 2 of the two profiles 1, and then the two profiles 1 are locked and fixed by the locking structures at both ends of the plug-in component 3, so that the two profiles 1 are fixedly connected together, and at least one of the locking structures at both ends of the plug-in component 3 is a quick locking structure 17, and the quick locking structure 17 can be quickly locked and unlocked.

[0029] By means of the quick locking structure 17, when connecting two profiles 1, after the two ends of the connector 3 are respectively inserted into the two profiles 1, the profile 1 and the connector 3 are quickly locked by the quick locking structure 17, thereby fixing the two profiles 1 in connection; conversely, when the two profiles 1 are just being disassembled, the quick locking structure 17 is opened to quickly loosen the profile 1 and the connector 3, and the connector 3 is pulled out of the profile 1, thereby separating the two profiles 1. Compared with the traditional structure that completely utilizes bolts for locking, the utility model can realize quick assembly and disassembly, and speed up the efficiency of frame assembly and disassembly.

[0030] A preferred technical solution is that the cross-section of the slot 2 is in an inverted "T" shape and is opened at the upper end of the profile 1. The slot 2 includes a slide groove 11. Both sides of the upper end of the slide groove 11 are bent and extended inward to form a rib 12. The ribs 12 on both sides are not connected to form an opening. The opening is arranged along the length of the slide groove 11, thereby forming an inverted "T"-shaped slot 2; the cross-section of the connector 3 is in an inverted "T" shape matching the slot 2, and the connector 3 includes an insertion rod 4 matching the slide groove 11 and a flange 5 protruding from the upper end of the insertion rod 4 and matching the opening.

[0031] The plug-in connector 3 inserted into the slot 2 can be confined within the slot 2 through the cooperation between the inverted “T”-shaped slot 2 and the plug-in connector 3 .

[0032] In a preferred technical solution, the quick locking structure 17 includes a circular rotating member 6 at least provided on one side of the flange 5, the circular rotating member 6 is circular in shape and is arranged sideways, the circular rotating member 6 is rotatably mounted on the side wall of the flange 5 through a rotating shaft 8, and the connection between the rotating shaft 8 and the circular rotating member 6 is arranged away from the center of the circular rotating member 6, so that the edge of the circular rotating member 6 has a proximal end 9 and a distal end 10, the proximal end 9 is closest to the rotating shaft 8, and the distal end 10 is farthest from the rotating shaft 8, and a pull piece 7 is extended outward from the edge of the circular rotating member 6, and the pull piece 7 is provided by pulling the pull piece 7. The plate 7 drives the circular rotating member 6 to rotate, and the pull plate 7 is connected between the proximal end 9 and the distal end 10 of the circular rotating member 6, avoiding the positions of the proximal end 9 and the distal end 10. The shortest distance from the distal end 10 of the circular rotating member 6 to the upper end of the insertion rod 4 is consistent with the thickness of the retaining edge 12, that is, when the circular rotating member 6 is rotated so that the distal end 10 is located at the lowermost end, the distance between the distal end 10 and the insertion rod 4 is consistent with the thickness of the retaining edge 12, and the distance from the rotation center of the circular rotating member 6 to the distal end 10 of the circular rotating member 6 is consistent with the distance from the rotation center of the circular rotating member 6 to the retaining edge 12.

[0033] After the connector 3 is inserted into the slot 2, the insertion rod 4 is matched in the slide groove 11, the convex edge 5 is matched in the opening, and the rib 12 is located between the circular rotating member 6 and the upper end of the insertion rod 4. The circular rotating member 6 is rotated by the pull piece 7, so that the distal end 10 of the circular rotating member 6 is downward against the upper end of the rib 12, so that the circular rotating member 6 and the upper end of the insertion rod 4 clamp the rib 12 together, thereby locking the connector 3 and the profile 1, thereby realizing the rapid assembly between the two profiles 1.

[0034] On the contrary, by rotating the circular rotating member 6 through the pull piece 7, the distal end 10 of the circular rotating member 6 is moved away from the rib 12, so that the rib 12 loses its extrusion and the fixed constraint between the connector 3 and the profile 1 is lost, so that the connector 3 can be pulled out of the profile 1, thereby realizing rapid disassembly between the two profiles 1.

[0035] According to a preferred technical solution, a circular rotating member 6 is provided on each side of the convex edge 5, and the two circular rotating members 6 are symmetrically arranged. A notch 14 corresponding to the convex edge 5 is opened at one end of the pull piece 7 facing the circular rotating member 6, and both ends of the notch 14 are respectively fixedly connected to the two circular rotating members 6. A rotating part 15 is provided on the upward protrusion of the convex edge 5, and the circular rotating member 6 is rotatably installed on the side wall of the rotating part 15.

[0036] A rotating member is provided on each side of the convex edge 5. When locking, the rotating members on both sides respectively abut against the retaining edges 12 on both sides of the opening to enhance the firmness of the locking.

[0037] According to a preferred technical solution, one end of the pull piece 7 away from the rotational connection position is tilted toward the unlocking rotation direction.

[0038] Since a certain external force needs to be applied in the process of rotating the circular rotating member 6 to make its distal end 10 abut against the retaining edge 12, it is easier to apply pressure through the tilted part of the pull piece 7.

[0039] According to a preferred technical solution, a plurality of anti-slip ridges 13 are provided on the surface of the pull piece 7 .

[0040] According to a preferred technical solution, the connector 3 is in a straight line shape or in an angle shape.

[0041] When the connector 3 is linear, it can connect two straight-line butted profiles 1; when the connector 3 is angled, it can connect two profiles 1 connected at a certain angle, preferably a right angle.

[0042] In a preferred technical solution, the locking structures at both ends of the connector 3 are quick locking structures 17 .

[0043] In a preferred technical solution, one of the locking structures at both ends of the connector 3 is a quick locking structure 17 , and the other is a bolt locking structure 16 .

[0044] When one end of the connector 3 is a bolt locking structure 16, one end of the connector 3 is always fixed to a profile 1 through the bolt locking structure 16. During assembly and disassembly, it is only necessary to lock and loosen the profile 1 at one end of the quick locking structure 17, and quick disassembly between the two profiles 1 can also be achieved. It is not necessary to lock and loosen both ends of the connector 3 to achieve assembly and disassembly.
