Embodiment
Below in conjunction with accompanying drawing the utility model is described, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model is achieved through the following technical solutions:
The utility model provides a kind of double end self tapping screw assembly at this, has a screw head 101, be used to drive the rotation of self tapping screw integral body, has first screw mandrel 102 that has spiral thread 102a, and second screw mandrel 103 that has spiral thread 103a, described first screw mandrel 102, second screw mandrel 103 and screw head 101 threes form the one fixed structure, and first screw mandrel 102 and second screw mandrel 103 are separately fixed at the both sides of screw head 101.
When the utility model double end self tapping screw assembly uses, can finish by a fastening swivel assembly 104, be used to be stuck on the screw head 101 fastening to the rotation of self tapping screw assembly integral body, fastening swivel assembly 104 has a swivel assembly body 104a, swivel assembly body 104 has a socket 104b, convenient screw mandrel by self tapping screw, the middle part has and the corresponding screw head fixed hole of screw head 101 shapes 104c, swivel assembly body 104a can be circle, fastening swivel assembly 104 injects by socket 104b, and fastening swivel assembly 104 is stuck on the self tapping screw assembly by fixed hole 104c, and under external force, drive the whole rotation of self tapping screw assembly, it is fastening to reach two screw mandrel.
Double end self tapping screw assembly described in the utility model can be used for fixing between two kinds of objects, and fixing etc. such as between door pocket and the body of wall can be used for other field equally; Concrete condition during according to use, the Hand of spiral that the screw thread 103a that has on the screw thread 102a that has on first screw mandrel 102 and second screw mandrel 103 is corresponding is identical or opposite, such as when be used between door pocket and the body of wall fixedly the time, the Hand of spiral that the screw thread 103a that has on the screw thread 102a that has on first screw mandrel 102 and second screw mandrel 103 is corresponding is opposite, during use, respectively with first screw mandrel 102, second screw mandrel, 103 correspondences place body of wall 105, door pocket 106, fastening swivel assembly 104 injects by socket 104b and places on first screw mandrel 102 or second screw mandrel 103, and fastening swivel assembly 104 is stuck on the screw head 101 by fixed hole 104c, this moment under external force, by being that circular swivel assembly body 104a drives the whole rotation of self tapping screw assembly, door pocket 106 is fastened on the body of wall 105 by two screw mandrel.Double end self tapping screw assembly described in the utility model can be used for other field equally.
