Detailed Description

The invention will be further described below in connection with specific embodiments.

Examples

As shown in fig. 1 to 4, which are schematic structural views of a self-locking screw according to a preferred embodiment of the present invention, the self-locking screw 100 of the present embodiment includes a screw rod 1, a nut 2 and a locking member 3, the screw rod 1 and the nut 2 are fixedly connected to each other by an integral type, and the locking member 3 is slidably connected to the screw rod 1 by a thread.

Retaining member 3 include threaded rod 4 and spacing contact pin 6, a port of threaded rod 4 on seted up fastening hole 8 for rotate threaded rod 4 with the help of the screwdriver, the other end of threaded rod 4 be provided with sliding tray 5, sliding tray 5 on be provided with connecting seat 7, connecting seat 7 fixed connection on sliding tray 5 for make and be connected between threaded rod 4 and the spacing contact pin 6.

The threaded rod 4 is connected with the sliding disc 5 through rotating and abutting against the connecting seat 7, and the limiting contact pins 6 are provided with two limiting contact pins which are fixedly connected to the sliding disc 5 and used for locking the self-locking screw 100 in the using process of the self-locking screw 100.

The lead screw 1 in be provided with internal thread hole 9, internal thread hole 9 in be provided with threaded rod 4 on the screw thread of screw thread looks adaptation, threaded rod 4 through with the internal thread hole 9 between the cooperation use screw thread sliding connection in lead screw 1 for make the spacing contact pin 6 on the threaded rod 4 can remove.
