DETAILED DESCRIPTION OF THE INVENTION

[0018] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0019] As shown in Figure 1 - Figure 3 FIG. - A rotary shoelace buckle includes a rotary shoelace buckle body 3 and a mounting mechanism 4. The rotary shoelace buckle body 3 is fixedly connected to the side of the shoe 1 through the mounting mechanism 4. A top shoelace hole 2 is provided on the side of the shoe 1. The mounting mechanism 4 includes a mounting base 10, a fixing rod 14, a compression spring 15, a movable rod 16 and a chuck 17. The mounting base 10 is fixedly connected to the side of the shoe 1 through a knob 5. A pair of symmetric fixing rods 14 are fixedly connected inside the mounting base 10. A compression spring 15 is sleeved outside the fixing rod 14. The movable rod 16 is movably connected to the fixing rod 14 through a connection groove 18 on the inner end wall and is fixedly connected to the outer side end of the compression spring 15. The chuck 17 is fixedly connected to the outer end wall.

[0020] As shown in Figure 1 - Figure 3 FIG. - In this embodiment, in order to facilitate the disassembly and replacement of the rotary shoelace buckle body 3 used on the side of the shoe through the mounting mechanism 4 after a failure or damage, a threaded short rod 19 is fixedly installed on the rear end wall of the mounting base 10. The threaded short rod 19 is inserted into the top shoelace hole 2. A threaded hole 6 is provided on the front end wall of the knob 5. The knob 5 is threadedly connected to the threaded short rod 19 through the threaded hole 6. Positioning ports 11 are respectively provided on the top and bottom surfaces of the mounting base 10. A groove 12 is provided on the inner wall of the positioning port 11. A retaining ring 13 is fixedly installed at the notch of the groove 12. The fixing rod 14 is fixedly installed at the bottom of the groove 12. A compression spring 15 is sleeved outside the fixing rod 14. The inner side end of the compression spring 15 is fixedly installed at the bottom of the groove 12. The movable rod 16 is fixedly installed on the outer side end of the compression spring 15. A connection groove 18 is provided on the inner end wall of the movable rod 16. The movable rod 16 is movably installed on the fixing rod 14 through the connection groove 18. A chuck 17 is also fixedly installed on the outer end wall of the movable rod 16. The chuck 17 passes through the retaining ring 13. A connection ring 7 is fixedly installed on the rear end wall of the rotary shoelace buckle body 3. A positioning block 8 corresponding to the positioning port 11 is fixedly installed on the inner wall of the connection ring 7. A card slot 9 corresponding to the chuck 17 is provided on the inner side wall of the positioning block 8;

[0021] The specific usage principle of the installation mechanism 4 cooperating with the rotary shoelace buckle body 3 is as follows: Insert the short threaded rod 19 installed on the rear end wall of the mounting base 10 into the hole of the top shoelace hole 2 opened on the shoe side 1. Then, screw the knob 5 into the short threaded rod 19 through the threaded hole 6 opened on the front end wall and thread it together with the short threaded rod 19, so as to pre-install and fix the mounting base 10 on the shoe side 1. When the rotary shoelace buckle body 3 is needed for the shoes, insert the connecting ring 7 installed on the rear end wall of the rotary shoelace buckle body 3 outside the mounting base 10. During the insertion process, the positioning block 8 installed on the inner wall of the connecting ring 7 is correspondingly inserted into the positioning opening 11 opened on the mounting base 10. When the positioning block 8 is inserted into the positioning opening 11, the clamping head 17 protruding in the positioning opening 11 will be squeezed. At this time, after being squeezed, the clamping head 17 will pass through the retaining ring 13 and enter the groove 12, and force the movable rod 16 to move inward in the groove 12 along the fixing rod 14 installed in the groove 12 through the connecting groove 18 opened on the inner end wall, and make the compression spring 15 sleeved outside the fixing rod 14 be forced to retract until the connecting ring 7 is completely inserted outside the mounting base 10 and the positioning block 8 is inserted into the positioning opening 11. At this time, after the clamping head 17 loses the extrusion of the positioning block 8, the compression spring 15 will recover and extend, and push the movable rod 16 outward, so that the clamping head 17 passes through the retaining ring 13 and enters the card slot 9 opened on the inner side wall of the positioning block 8, so as to quickly position and snap-install the rotary shoelace buckle body 3 on the shoe side 1. And when the rotary shoelace buckle body 3 is damaged and cannot be used, the rotary shoelace buckle body 3 can be directly pulled outward forcefully, and the rotary shoelace buckle body 3 can be pulled off. After disassembly, a new rotary shoelace buckle body 3 can be installed and replaced for use, so as to facilitate the disassembly and replacement of the rotary shoelace buckle body 3 in time after a failure or damage occurs during the use of the rotary shoelace buckle body 3, and improve the practicability of the rotary shoelace buckle body 3.

[0022] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, various improvements can be made to it and components therein can be replaced with equivalents, or some technical features therein can be equivalently replaced without departing from the scope of the present invention. All should be included within the protection scope of the present invention within the spirit and principle of the present invention.
