Abstract
The invention discloses a fastening type screw spike. The fastening type screw spike is characterized by comprising a nut, a fastening body, a connecting body and a screw tip; the fastening body comprises a first main fastening body and a second main fastening body, and the nut is movably connected with the first main fastening body through internal threads and external threads; one end of the connecting body is movably connected with the first main fastening body through internal threads and external threads; and the other end of the connecting body is movably connected with the second main fastening body through internal threads and external threads. The fastening type screw spike has the advantages that the internal threads and the external threads are matched, so that the screw spike is detachable; and meanwhile, the connecting body is movably connected between the first main fastening body and the second main fastening body, so that the fastening effect is better.
Description
Technical field
The present invention relates to mechanical Component technical field, be specifically related to a kind of fastening type screw.
Background technique
Existing a kind of fastening screw trip bolt, it has the head of a nail, rivet nut, nail tip end, is provided with arcuate thread at rivet nut periphery.When using the fastening screw trip bolt of this structure, drive in and compare effort, the head of a nail is easily out of shape; In addition, screw is entering within the walls after certain distance, and screw and the body of wall wall ash produced that rubs is blocked in the screw thread of rivet nut, again then toward when driving within the walls, wall ash and then rivet nut, together toward squeezing within the walls, losing fastening effect, making the combination degree of screw and body of wall firm not; Simultaneously certain part impaired of the easy impaired or screw of the screw tip of fastening screw nail, there will be abandoning of whole screw, wastes too large.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, now provide a kind of fastening effect good, dismountable, achieve the screw that the fastening effect of recycling is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of fastening type screw, its innovative point is: comprise nut, fastener, connecting body and screw tip, described fastener comprises the first fastener and the second fastener, and described nut is flexibly connected by internal and external threads with the first fastener; One end of described connecting body is flexibly connected by internal and external threads with the first fastener; The other end of described connecting body is flexibly connected by internal and external threads with the second fastener.
Further, the structure of described nut is that semi-circular structure and cylindrical structure are formed by fixedly connecting, and described nut top offers a groove, and described groove is cruciform groove.
Further, the structure of described connecting body comprises two cylindrical body projections that cylindrical body also has cylindrical body both sides, described two cylindrical body projections are flexibly connected with the first fastener, the second fastener, and the diameter of described connecting body is less than the diameter of the first fastener and the second fastener.
Beneficial effect of the present invention is as follows:
(1) the present invention's cooperatively interacting by internal and external threads, achieves the local detachable of screw, is convenient to the local replacing of screw.
(2) the present invention by being connected with a connecting body between the first fastener and the second fastener, makes fastening effect better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is plan view of the present invention.
Embodiment
By particular specific embodiment, embodiments of the present invention are described below, person skilled in the art scholar the content disclosed by this specification can understand other advantages of the present invention and effect easily.
As depicted in figs. 1 and 2, a kind of fastening type screw, comprises nut 1, fastener, connecting body 3 and screw tip 5, and fastener comprises the first fastener 2 and the second fastener 4, and nut 1 is flexibly connected by internal and external threads with the first fastener 2; One end of connecting body 3 is flexibly connected by internal and external threads with the first fastener 2; The other end of connecting body 3 is flexibly connected by internal and external threads with the second fastener 4, and the present invention's cooperatively interacting by internal and external threads, achieves the local detachable of screw, is convenient to the local replacing of screw.
The structure of nut 1 is that semi-circular structure and cylindrical structure are formed by fixedly connecting, and nut 1 top offers a groove 6, and groove 6 is cruciform groove.
The structure of connecting body 3 comprises two cylindrical body projections that cylindrical body also has cylindrical body both sides, and two cylindrical body projections are flexibly connected with the first fastener 2 and the second fastener 4, and the diameter of connecting body 3 is less than the diameter of the first fastener 2 and the second fastener 4.
The present invention's cooperatively interacting by internal and external threads, achieves the detachable of screw, meanwhile, is connected with a connecting body 3, makes fastening effect better between the first fastener 2 and the second fastener 4.
Above-described embodiment is preferred embodiment of the present invention; it is not the restriction to technical solution of the present invention; as long as without the technological scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of patent of the present invention.
