When it is inconvenient, so a kind of ground connection plug pin is provided solve the above-mentioned problem very it is necessary to.
Utility model content
The purpose of this utility model is to provide a kind of ground connection plug pins, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions: a kind of ground connection plug pin, including bushing and drawing
Bar, the pull rod are socketed in bush inside, and the bushing includes limited location snap ring and spacing collar, and the limited location snap ring is fixed to be connected
It is connected to integrally formed spacing collar one end, the pull rod includes screw rod and connector, and the connector is fixedly connected on one
Body formed screw rod one end, the connector outside are equipped with inclined surface, and the connector of the tie rod end is connected to the limit of bushing
Position sleeve inner.
Preferably, the junction of the spacing collar and limited location snap ring is provided with groove, and the groove is ring structure.
Preferably, the inside grooves bottom end is provided with the first circular arc chamfering, and the recess sidewall upper end is provided with the second circular arc
Chamfering.
Preferably, the tilt angle of the inclined surface and vertical direction is 5 degree.
Compared with prior art, the utility model has the beneficial effects that a kind of ground connection plug pin of the utility model, structure are new
Grain husk replaces original welding block welding to install, has the advantages that using bushing and pull rod interference fit installation
1, installation is simple, quick, and from cost of labor, the time needed for each ground connection plug pin installation is about 1-2 points
Clock, working efficiency are significantly larger than the weld interval of single welding block, and working efficiency is very high, can save a large amount of human costs；
2, all cold working of whole installation process so as to avoid the various defects of welding heat affected zone, such as is welded
The potential defects such as crackle, tissue crystal grain becomes larger, thermal stress and tissue overheating, tissue burning；
3, welding is very big to the body harm of operator as a harmful work post；Ground pin is installed as cold machining process
Mounting means can improve the working environment of operator to the harm very little of human body.Relative to welding, a kind of green ring can be considered
Protect technique；
4, convenient disassembly, later period cooperate self-locking nut to use, it is only necessary to which one punching pin or awl, that is, detachable；
5, widely applicable, uneven surface, deck, partition, steel case, rail, blind hole or not easy-operating region.
