Description

Technical Field

[0001] The utility model belongs to the technical field of bolts, and more specifically, particularly relates to a double-bolt head bolt with anti-slip threads. Background Art

[0002] Stud bolts, also called stud screws or studs, are used for the fixed connection function of connecting machinery. Stud bolts have threads on both ends. The stud bolts in the middle are either thick or thin. They are generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, cranes, large-span steel structures and large buildings. Stud bolts generally need to be surface treated. There are many types of bolt surface treatments, and the commonly used ones are electroplating, blackening, oxidation, phosphating, non-electrolytic zinc sheet coating, etc. However, electroplated fasteners account for a large proportion in the actual use of fasteners, especially in automobiles, tractors, home appliances, instrumentation, aerospace, communications and other industries and fields.

[0003] Based on the above, the inventors have discovered the following problems: during the use of existing stud bolts, when they are used for a long time, oxidation reaction will easily occur on the surface and cause rust, which will reduce the service life of the bolts. At the same time, during the normal use of the bolts, when the vibration amplitude is large, it will cause surface loosening and other phenomena, or it will easily cause internal thread slippage during disassembly operations, indirectly causing inconvenience to the staff.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a double-bolt head bolt with anti-slip thread is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose and effect of the double-bolt head bolt with anti-slip wire of the utility model are achieved by the following specific technical means:

[0006] A double-bolt head bolt with an anti-slip thread, comprising a double-headed bolt, a group of arc-shaped through holes are opened at both ends of the double-headed bolt, a group of threads are opened at both ends of the double-headed bolt, a group of nuts are connected and installed at both ends of the double-headed bolt, a group of through holes are opened on the two side surfaces of the nut, and an anti-slip thread mechanism is installed inside the through hole.

[0007] Furthermore, a threaded hole is provided inside the nut 1, and the threaded hole engages with the thread.

[0008] Furthermore, the anti-slip wire mechanism includes a screw rod, which is installed through the interior of the arc-shaped through hole, and a screw head is fixedly installed at one end of the screw rod, and a nut 2 is installed at the end of the screw rod away from the screw head.

[0009] Furthermore, the screw head and the second nut are respectively installed inside the through hole.

[0010] Furthermore, the second nut is engaged with the screw rod.

[0011] Furthermore, the surface of the stud bolt is plated with a rust inhibitor.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the cooperation between the screw head, the screw rod and the nut two, when the staff uses the bolt for installation and fixing, they can first install the nut one to the surface of the stud bolt, and then align the through hole on the surface of the nut one with the arc through hole, the screw rod can be passed through the arc through hole and the screw rod can be fixed with the nut two, and then the nut one can be fixed, avoiding the phenomenon of thread slippage caused by some special factors during the use of the stud bolt. This design can make the stability efficiency of the nut one better, and greatly increase the practicality, and indirectly improve the use efficiency of the stud bolt.

[0014] Through the design of the rust inhibitor, the stud bolt can be effectively prevented from rusting on its surface due to long-term use, thereby indirectly increasing the service life of the stud bolt, which is very simple. BRIEF DESCRIPTION OF THE DRAWINGS
