[0026] Embodiment

[0027] Refer to Figures 1 to 3 , a toggle bolt with a hidden decoration structure proposed by the present utility model includes a toggle bolt main body 10 and a connecting screw 20; it further includes a decorative cover 30;

[0028] A positioning sink 21 structure is provided at the end of the connecting screw 20; the decorative cover 30 is provided with a connecting stud 31; the connecting stud 31 can be snapped into the positioning sink 21, and the decorative cover 30 can block the end of the connecting screw 20 and the end of the toggle bolt main body 10.

[0029] In the present utility model, after the toggle bolt main body 10 and the connecting screw 20 are locked and fixed, the decorative cover 30 is detachably embedded outside the connecting screw 20; the decorative cover 30 can be directly centered and nested outside the connecting screw 20 by means of the connecting stud 31 cooperating with the positioning sink 21 of the connecting screw 20, so as to block the end of the connecting screw 20 and the end of the toggle bolt main body 10; the decorative cover 30 is convenient to disassemble and install, and makes the overall appearance of the hardware structure and the panel coordinated and beautiful.

[0030] In this embodiment, in order to facilitate locking the connecting screw 20 to the toggle bolt main body 10, a force application groove 22 is provided at the end of the connecting screw 20, and the force application groove 22 is communicated with the positioning sink 21.

[0031] Specifically, the force application groove is in a straight, cross or internal hexagonal structure. Or the force application structure of other common hardware connectors.

[0032] In this embodiment, in order to conveniently align and snap the decorative cover 30 into the positioning sunk groove 21 at each rotation angle, so as to achieve the effect of covering the end of the connecting screw 20 and the end of the expansion bolt body 10. The positioning sunk groove 21 is located in the middle of the end and has a round hole groove structure; the connecting convex column 31 has a cylindrical structure.

[0033] In this embodiment, several rib structures 32 are provided on the outer side of the connecting convex column 31. The decorative cover 30 is usually a plastic part. These rib structures 32 are staggered from each other, which can provide a certain deformation space, so that the connecting convex column 31 is deformed and pressed into the groove structure, improving the firmness of the fixation between the connecting convex column 31 and the groove structure. At the same time, the strength of the connecting convex column 31 can be increased.

[0034] Specifically, the rib structures 32 are evenly spaced along the circumferential direction.

[0035] Furthermore, the rib structure 32 is provided with a partition groove 33, and the partition groove 33 divides the rib structure 32 into front and rear sections. The partition groove 33 separates the front end and the rear end of the rib structure 32, that is, while ensuring the relatively high strength of the connecting convex column 31 and not being easily bent and deformed, the front rib structure 32 can be made relatively soft, and can be better deformed and pressed into the positioning sunk groove 21 for fixation.

[0036] In this embodiment, in order to better cover and block the end of the expansion bolt body 10; the outer edge of the decorative cover 30 is provided with a shielding flange 34 extending towards the end of the expansion bolt body 10.

[0037] Certainly, the present invention is not limited to the above embodiments.
