Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail;
As shown in Figure 1 to Figure 3, a kind of Anti-loose screw, comprise the screw cap 2 be provided with above screw rod 1 and screw rod 1, screw head 3 is provided with below screw rod 1, cavity A4 and cavity B5 is offered in screw rod 1, cavity A4 is positioned at below cavity B5, spring 6 is provided with in cavity A4, two blank pipes 7 are provided with below cavity A4, two fixing nails 8 are provided with below spring 6, fixing nail 8 lower end is placed in blank pipe 7, cavity A4 upper and lower surface all offers an opening 9, opening 9 diameter is less than spring 6 diameter, newel 10 is provided with above spring 6, newel 10 is placed in cavity B5, the first plate washer 11 is provided with in cavity B5, second plate washer 12 and third gear plate 13, screw cap 2 offers a cross bakie 14, screw cap 2 avris offers a cell body 15, an adjustable lever 16 is provided with in cell body 15, adjustable lever 16 is T-shaped, screw cap 2 arranged outside has a shell 17, screw rod 1 outer surface is provided with screw thread 18, the length of side of cross bakie 14 is less than newel 10 diameter, newel 10 center is equal to the distance of the first plate washer 11 and the second plate washer 12, newel 10 center to the distance of third gear plate 13 equal newel 10 center to the second plate washer 12 distance 1/2nd.
During use, by cross bakie 14, Anti-loose screw is screwed in object, in the cell body 15 that screw cap 2 offers, take out adjustable lever 16, adjustable lever 16 is inserted the position regulating newel 10 in cross bakie 14, newel 10 is placed in below the first plate washer 11, second plate washer 12 or third gear plate 13, and then acts on spring 6, thus fixing nail 8 is hammered in object, namely complete this operation.
The design of adjustable lever 16, make it easy to directly regulate the position of newel 10 between each baffle plate by cross bakie 14, thus extrusion spring 6 pairs of fixing nails 8 are exerted all one's strength, fixing nail 8 enters in object, and then screw is not easily loosened, screw cap 2 is provided with shell 17, dust is not easily entered in the cavity of screw rod 1, thus extends its working life.
