DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The present invention provides a technical solution: a rotary buckle device that is easy to install and disassemble, comprising a female buckle top cover 1 and a rotating column 2, a rectangular groove 3 is opened on the upper side of the female buckle top cover 1, a circular through hole 4 is opened in the middle of the rectangular groove 3 of the female buckle top cover 1, raised clamping heads 5 are fixedly arranged on both sides of the rectangular groove 3 of the female buckle top cover 1, and arc grooves 6 are opened on both sides of the rectangular groove 3 of the female buckle top cover 1. In order to facilitate rotation and insertion, the two groups of arc grooves 6 must be part of the same circle, so the arc lengths and radius dimensions of the two groups of arc grooves 6 are equal, and the centers of the two groups of arc grooves 6 coincide.

[0022] An expansion column 7 is fixedly arranged on the lower surface of the female buckle top cover 1 at the edge of the circular through hole 4. In order to facilitate drilling into the clamping position, chamfers are provided at one end of the rotating column 2 and the expansion column 7. In order to enhance the clamping effect of the expansion column 7 on the object, an annular groove 16 is provided on the outer surface of the expansion column 7. A cross groove 8 is provided at the end of the expansion column 7 away from the female buckle top cover 1, and a cylindrical groove 9 is provided at the end of the expansion column 7 close to the female buckle top cover 1. A truncated cone groove 10 is connected to one side of the cylindrical groove 9, and both the cylindrical groove 9 and the truncated cone groove 10 are connected to the cross groove 8.

[0023] See also Figure 1-5 A clamping block 11 is fixedly provided at one end of the rotating column 2, and both sides of the clamping block 11 are movably clamped in the arc groove 6. In order to achieve a better clamping effect, arc blocks 15 are fixedly provided on both sides of the clamping block 11. The arc length and radius of the two groups of arc blocks 15 are equal, and the center of the two groups of arc blocks 15 coincide with the center of the clamping block 11, and the radius of the arc block 15 is smaller than the radius of the arc groove 6. A connecting block 12 is provided on the side of the clamping block 11 away from the rotating column 2, and movable plates 13 are rotatably connected to the two sides of the connecting block 12 through movable pins. The two groups of movable plates 13 are provided with clamping grooves 14, and the clamping grooves 14 are clamped in the protruding clamping head 5.

[0024] In order to enhance the connection strength between the movable plate 13 and the connecting block 12, it is necessary to increase the length of the connection, and set the shape of the two groups of movable plates 13 to be a right-angled trapezoid. The two groups of movable plates 13 are combined into a rectangular plate, and the size of the rectangular plate is not larger than the size of the rectangular groove 3. After installation, the clamping block 11 is in the arc groove 6, and the movable plate 13 is clamped in the rectangular groove 3, so the rectangular plate formed by the combination of the two groups of movable plates 13 is required to be perpendicular to the clamping block 11.

[0025] Working principle: insert the expansion column 7 into the position where the buckle needs to be installed, rotate the two sets of movable plates 13 to fit together, hold the movable plate 13, insert the rotating column 2 into the circular through hole 4, and pass through the circular through hole 4, the cylindrical groove 9 and the truncated cone groove 10 in turn during the insertion process. When the rotating column 2 is inserted into the truncated cone groove 10, the lower end of the expansion column 7 expands outward along the cross groove 8 to clamp the part that needs to be clamped. The insertion process of the rotating column 2 ends until the clamping block 11 fits into the rectangular groove 3. Then, hold the movable plate 13 to rotate the clamping block 11 90°, and the clamping block 11 is clamped into the arc groove 6. Then, make the movable plate 13 fit and rotate downward to fit the rectangular groove 3. During the fitting process, the clamping groove 14 on the movable plate 13 is clamped into the raised clamping head 5. The installation is completed and the disassembly process can be reversed.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
