Abstract
The invention relates to an anti-loose screw which is characterized by comprising a first threaded rod, a second threaded rod and a third threaded rod which are cylindrical, wherein the second rod is positioned between the first rod and the third rod, and the diameter of the second rod is larger than that of each of the other two rods. By the aid of the three rods with different rod diameters, two connected objects are respectively fixedly connected with the rods in a threaded manner when in connection, and loose is effectively prevented when the objects are connected and fastened.
Description
Technical field
The present invention relates to a kind of fastening piece, relate in particular to a kind of anti-loosening screw rod.
Background technique
Screw rod is used for plastic molding equipment more, as plastic material extruder, injection machine etc.Screw rod and machine barrel are the core components of plastic molding equipment, are the parts of heating extrusion plasticizing, are the cores of plastics machinery.Screw rod is widely used in machining center, CNC machine, numerically controlled lathe, injection machine, line cutting, grinding machine, milling machine, the silk of being careful, fast wire, PCB driling machine, finishing impression machine, carving mill machine, sparkover machine, sting the tooth machine, planer, large-scale vertical lathe gantry mill etc.
The screw rod that uses is based on screw thread rotation at present, it is affixed by screw thread and screw rod respectively to be connected thing with two when connecting two objects, connect and fastening object in because screw rod skids and becomes flexible, cause to be connected the thing loose or dislocation, thereby cause a series of problems and accident.
Summary of the invention
The objective of the invention is provides a kind of anti-loosening screw rod in order to overcome the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of anti-loosening screw rod, it is characterized in that comprise screwed first body of rod, second body of rod and the 3rd body of rod, each body of rod is cylindrical, described second body of rod is between first body of rod and the 3rd body of rod, and the diameter of second body of rod is bigger than the diameter of other two bodies of rod.
Further, arc transition is adopted in described first body of rod and second body of rod joint.
Further, arc transition is adopted in described second body of rod and the 3rd body of rod joint.
Further, the center line of described first body of rod, second body of rod and the 3rd body of rod is on same straight line.
Further, described first body of rod, second body of rod and the 3rd body of rod are one-body molded.
Further, the end of described the 3rd body of rod is connected with six-sided nut.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arranging three different bodies of rod of bar footpath, it is affixed by screw thread and each body of rod respectively to be connected thing with two when connecting two objects, in connection and fastening object, prevents the generation of loosening phenomenon effectively.
