[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 3 、 Figure 4 The utility model provides an embodiment: a shock-resistant and anti-loosening rivet, comprising a rivet head 1, a rivet rod 4 fixedly connected to the bottom end of the head 1, a rivet sleeve 2 sleeved on the outer wall of the rod 4, a rivet cap 3 provided on the outer wall of the sleeve 2, a support assembly provided on the outer wall of the sleeve 2, the support assembly comprising a support block 21 providing support, the support block 21 passes through and is slidably connected to the outer wall of the sleeve 2, the outer wall of the sleeve 2 is provided with a through slot 25 for the support block 21 and the support block 2 23 to move, and the outer wall of the sleeve 2 is close to the through slot A positioning groove 22 is provided on the left side of 25 for providing movement of the positioning block 24 and limiting the movement distance of the positioning plate 28. The support block 1 21 is slidably connected to the inner wall of the through groove 25. The bottom end of the support block 1 21 is provided with a circular groove 29 for placing a spring 210. The inner wall of the circular groove 29 is fixedly connected to one end of the spring 210 which can absorb the squeezing force after being squeezed by the support block 23 to achieve a buffering effect and improve the shock resistance and anti-loosening effect. The other end of the spring 210 is fixedly connected to the support block 23 which can limit the guide block 26, the guide groove 27 and the positioning plate 28.

[0032] Reference Figure 1 - Figure 3The outer wall of the nail sleeve 2 is provided with an adjustment component, which includes a thread groove 31. The thread groove 31 is opened on the outer wall of the nail sleeve 2 near the top of the nail cap 3. The nail cap 3 is threadedly connected to the thread groove 31. The nail cap 3 can be threadedly connected to the thread groove 31 by rotating the nail cap 3 to adjust the position of the nail cap 3, so as to adapt to the distance between objects and tighten objects of different thicknesses.

[0033] Reference Figure 1 、 Figure 3 、 Figure 4 The rear surface of the support block 23 is fixedly connected with a guide block 26 that slides in the guide groove 27 to support and position the support block 23. The rear surface of the support block 1 21 is fixedly connected with a positioning plate 28 that provides support and drives the support block 1 21 and the support block 2 23 to move outward. The positioning plate 28 is slidably connected to the inner wall of the nail sleeve 2. The right side of the positioning plate 28 is fixedly connected with a positioning block 24 that supports the positioning plate 28 and is provided with two groups. The other group of positioning blocks 24 is slidably connected to the inner wall of the positioning groove 22. The two groups of positioning blocks 24 are symmetrically arranged with the center line of the positioning plate 28 as the axis of symmetry, and the positioning groove 22 supports the positioning block 24.

[0034] Reference Figure 1 、 Figure 3 、 Figure 4 The top of the extrusion groove 211 is set as an inclined surface, and the positioning plate 28 slides on the inner wall of the extrusion groove 211. The top of the extrusion groove 211 is set as an inclined surface, so that the top of the positioning plate 28 can be squeezed. The inclined surface allows the positioning plate 28 to move outward, so that the support block 1 21 and the support block 2 23 cooperate to move outward to fasten the object between the nail cap 3, thereby increasing the fastening and stabilizing effect. At the same time, the support block 1 21 can be squeezed and positioned in conjunction with the deformation of the nail sleeve 2, thereby further improving the fastening effect. At the same time, the spring 210 can be used to absorb the force generated by vibration to achieve an increased buffering effect, further improving the shock resistance and anti-loosening effect.

[0035] Reference Figure 1 、 Figure 2 The bottom end of the nail sleeve 2 is fixedly connected with a positioning ring 32 that can limit the nail cap 3. The positioning ring 32 is set at the bottom end of the nail cap 3, and the positioning ring 32 can prevent the nail cap 3 from moving out of the bottom end of the nail sleeve 2.

[0036] Working principle: When in use, the rod 4 is moved to make the nail sleeve 2 pass through the holes of the two groups of objects that need to be fastened, so that the nail cap 3 contacts the top of the object. At the same time, the nail cap 3 can be rotated and threadedly connected with the thread groove 31 according to the distance between the objects, so that the nail cap 3 can be adjusted according to the distance between the objects, thereby improving the applicability. The rod 4 is moved by the tool to pull the head 1 to move and squeeze the nail sleeve 2, so that the nail sleeve 2 is deformed. At the same time, the rod 4 moves to drive the extrusion groove 211 to move and squeeze the top of the positioning plate 28, so that the positioning plate 28 moves outward to drive the positioning block 24 to be slidably connected in the positioning groove 22. At the same time, the positioning plate 28 drives the support block 1 21 and the support block 23 to move outward. After moving to the outside of the nail sleeve 2, the support block 23 contacts the bottom end of the object. At the same time, the reverse force of the spring 210 caused to be squeezed causes the support block 23 to slide downward to the bottom end of the inner wall of the through groove 25, so that the support block 1 21 and the positioning plate 28 are limited after the through groove 25 is stuck in the bottom end of the through groove 25. At the same time, the support block 1 21 is squeezed after the nail sleeve 2 is deformed, so that the support block 1 21 and the support block 2 23 can be squeezed by the deformation of the nail sleeve 2. The support block 2 23 is limited and clamped by the nail sleeve 2, so that the object can be firmly fastened, thereby improving the fastening effect, preventing the objects from loosening after the deformation of the nail sleeve 2. After the deformation of the nail sleeve 2 is loosened, the object can be continued to be fastened by the support block 1 21 and the support block 2 23, thereby improving the fastening effect.

[0037] When vibration or impact occurs, the object directly squeezes the support block 23, causing the support block 23 to vibrate and then squeeze the spring 210. The spring 210 absorbs the squeezed force, and the spring 210 uses its own elastic properties to cleverly buffer, disperse and transform these forces through expansion and contraction deformation, etc., ensuring that the entire system can still maintain relative stability and safety when facing complex and severe situations such as external vibration or impact, and effectively resisting the impact and interference of these external adverse factors on the system.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
