Abstract
The utility model relates to an anti-disengaging screw rod. The anti-disengaging screw rod is characterized by comprising a first rod body, a second rod body and a third rod body all of which are provided with threads and are in a cylindrical shape, the second rod body is located between the first rod body and the third rod body, and the diameter of the second rod body is larger than the diameter of the first rod body and the diameter of the third rod body. Due to the fact that the three rod bodies with different diameters are arranged, two connected articles are respectively and fixedly connected with the rod bodies through the threads when being connected, and the loosening phenomenon can be effectively prevented during the process of connecting and fastening the articles.
Description
Technical field
The utility model relates to a kind of fastening piece, relates in particular to a kind of anti-loosening screw rod.
Background technique
Screw rod is used for plastic molding equipment, as plastic section extruding machine, 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, slow wire feeding, fast wire winding, PCB driling machine, carving machine, carving milling machine, sparkover machine, stings tooth machine, planer, large-scale vertical lathe gantry mill etc.
The screw rod using at present be take screw thread rotation as main, when connecting two objects, by two, be connected thing affixed by screw thread and screw rod respectively, connect and fastening object in because screw rod skids and loosening, cause and be connected thing loose or dislocation, thus initiation series of problems and accident.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of anti-loosening screw rod is provided.
The utility model is to be 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 larger than the diameter of other two bodies of rod.
Further, described first body of rod and the second body of rod joint adopt arc transition.
Further, described second body of rod and the 3rd body of rod joint adopt arc transition.
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 beneficial effects of the utility model are: the utility model is by arranging three different bodies of rod of bar footpath, while connecting two objects, by two, be connected thing affixed by screw thread and each body of rod respectively, in connection and fastening object, effectively prevent the generation of loosening phenomenon.
