In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, a snap-fit ​​connection structure includes a first profile 1 and a second profile 2. The first profile 1 is provided with a snap-fit ​​groove 101, and the second profile 2 is provided with a snap-fit ​​post 201. The snap-fit ​​post 201 is rotatably engaged with the snap-fit ​​groove 101. The snap-fit ​​groove 101 is provided with an inlet and an outlet. A main snap-fit ​​part 1021 and a secondary snap-fit ​​part 1022 are respectively provided on both sides of the inlet and outlet. A main contact surface 103 is provided on one side of the main snap-fit ​​part 1021. 1. A secondary engaging surface 1032 is provided on one side of the secondary engaging part 1022. The engaging post 201 is a cylindrical engaging post 201. A limiting protrusion 2012 is provided on the engaging post 201. An engaging recess 2011 is provided on the engaging post 201. A contact surface 2021 and a contact surface 2022 are provided on the second profile 2. The width of the main engaging part 1021 and the width of the secondary engaging part 1022 are smaller than the width of the engaging recess 2011.

[0030] The working principle of this snap-fit ​​connection structure is as follows: First, when the engaging post 201 is located in the engaging groove 101, the limiting protrusion 2012 on the engaging post 201 abuts against the groove wall of the engaging groove 101. At the same time, the engaging recess 2011 engages with the secondary engaging part 1022, and the contact surface 2021 on the second profile 2 contacts the secondary contacting surface 1032. At this time, the first profile 1 and the second profile 2 are in an engaged state. When it is necessary to remove the second profile 2 from the first profile 1, the second profile 2 is rotated, so that the secondary engaging part 1022 on the first profile 1 disengages from the limiting recess. Finally, when the contact surface 2022 is rotated to contact the main contacting surface 1031, the second profile 2 can be moved. When the engaging post 201 is removed from the engaging groove 101, the second profile 2 can be separated from the first profile 1. To make the first profile 1 and the second profile 2 engage together, firstly, move the second profile 2 toward the first profile 1 so that the engaging post 201 enters the engaging groove 101 and the contact surface 2022 is in a state of being close to the main contact plane 1031. Then rotate the first profile 1. When it is rotated until the secondary contact plane 1032 contacts the contact surface 2021, the engaging concave 2011 engages with the secondary engaging part 1022, and the limiting protrusion 2012 is close to the groove wall of the engaging groove 101, thus completing the engagement of the first profile 1 and the second profile 2.

[0031] In summary, when both the first profile 1 and the second profile 2 are relatively long, and the length of the space they occupy is insufficient to accommodate the combined length of the first profile 1 and the second profile 2, this type of rotating buckle can achieve a detachable connection between the first profile 1 and the second profile 2.

[0032] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the main engaging part 1021 and the secondary engaging part 1022 have the same shape and size, and the engaging groove 101 is an axisymmetric engaging groove 101.

[0033] The main engaging part 1021 and the secondary engaging part 1022 have the same shape and size, and the engaging groove 101 is an axisymmetric engaging groove 101. In this way, both the main engaging part 1021 and the secondary engaging part 1022 can cooperate with the engaging recess 2011, which can ensure that the first profile 1 can engage with the second profile 2 in both the upper and lower directions.

[0034] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the contact surface 2021 is perpendicular to the contact surface 2022.

[0035] As attached Figure 1 Appendix Figure 2 AppendixFigure 3 and appendix Figure 4 As shown, the locking post 201 includes, but is not limited to, a hollow locking post 201, and the hole inside the locking post 201 can be circular or square.

[0036] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the main bonding plane 1031 and the secondary bonding plane 1032 are located in the same plane.

[0037] The main bonding plane 1031 and the secondary bonding plane 1032 are in the same plane, which can ensure that the first profile 1 can be stably engaged with the second profile 2 in both the upper and lower directions.

[0038] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the limiting protrusion 2012 is trapezoidal in shape, and part of the groove wall of the engaging groove 101 is trapezoidal in shape.

[0039] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 As shown, the limiting protrusion 2012 is a right trapezoidal shape, and part of the groove wall of the engaging groove 101 is a right trapezoidal shape.

[0040] The right-angled trapezoidal limiting protrusion 2012 fits tightly against the trapezoidal groove wall of the engaging groove 101, which can ensure the stability of the engagement between the first profile 1 and the second profile 2.

[0041] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and appendix Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 As shown, the first profile 1 is provided with reinforcing ribs.

[0042] It should be further noted that the first profile and the second profile can be made of plastic or metal. Except for the interlocking parts, the first profile and the second profile can be of any shape, including but not limited to round tubes and square tubes.
