[0020] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.
[0021] Embodiment 1:
[0022] As Figures 1-4The utility model provides a kind of screw with nail cap reinforcing structure, including screw main body 1, the top of screw main body 1 is provided with nail cap 2, the lower surface of nail cap 2 is provided with hollow buffer pad 4, the lower surface of hollow buffer pad 4 is provided with support pad 6, the top of nail cap 2 is provided with dismounting groove 3, the inner wall of dismounting groove 3 is provided with inner recess 7, the inner wall of inner recess 7 is fixedly connected with elastic folded plate 8, the edge side of the outer surface of elastic folded plate 8 is fixedly connected with fastening clamp strip 10.
[0023] Specifically, the inside of hollow buffer pad 4 is provided with non-newtonian fluid containing cavity 5.
[0024] Specifically, inner recess 7 is relatively provided on the inner wall of dismounting groove 3, and elastic folded plate 8 is linearly arranged along the inner wall of inner recess 7.
[0025] Specifically, the edge of the outer surface of elastic folded plate 8 is fixedly connected with the inner wall of inner recess 7, and fastening clamp strip 10 is arranged on the side of elastic folded plate 8 away from inner recess 7.
[0026] Specifically, the inner surface of elastic folded plate 8 is fixedly connected with elastic arc plate 9, and the outer surface of fastening clamp strip 10 is matched with the inner surface of inner recess 7.
[0027] Specifically, the outer surface of fastening clamp strip 10 is provided with nanometer anti-skid line 11.
[0028] The working principle and beneficial effects of the above embodiments.
[0029] In use, a screwdriver is inserted into dismounting groove 3, and the inclined portion of the outer surface of fastening clamp strip 10 extends out of inner recess 7 in a natural state. After the screwdriver is inserted, the bottom end of the screwdriver passes the inclined surface of fastening clamp strip 10, so that fastening clamp strip 10 is subjected to a pushing force and moves into inner recess 7. Elastic folded plate 8 and elastic arc plate 9 are subjected to extrusion. After the screwdriver is completely inserted into dismounting groove 3, fastening clamp strip 10 is pressed against the outer surface of the screwdriver under the extrusion of the elasticity of elastic folded plate 8 and elastic arc plate 9. At the same time, nanometer anti-skid line 11 increases the friction between fastening clamp strip 10 and the screwdriver, so that the screwdriver is not easy to slip off when the screwdriver is rotated to install the screw, and the slot opening of dismounting groove 3 is prevented from being damaged. When the screw is tightened, the torque of the screwdriver is uniformly transmitted to nail cap 2 through fastening clamp strip 10. Under the support of fastening clamp strip 10, the force exerted by the screwdriver on nail cap 2 is not easy to damage nail cap 2. When the screw is slightly moved due to external vibration, the elasticity of hollow buffer pad 4 and the non-newtonian fluid in non-newtonian fluid containing cavity 5 can weaken the vibration from the fixed object, so that nail cap 2 is more durable.
