This bolted insulating bar has following deficiency:
1. the bolted insulating bar has only the sleeve of two kinds of specifications to pull, and can only tighten or unscrew the bolt of two kinds of specifications, and the scope of application is little;
2. when tightening or unscrewing the electric device of eminence and the bolt on the equipment with the bolted insulating bar, be with holding the bolted insulating bar with the fastening insulating bar application of force of hand rotating bolt, effort, moment of torsion are little.
In the prior art, less than the big polytypic bolted insulating bar of big, the laborsaving moment of torsion of the scope of application.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, to propose the polytypic bolted insulating bar that a kind of scope of application is big, laborsaving, moment of torsion is big.
The utility model is realized with the following method.
Polytypic bolted insulating bar has the tubular insulating bar, the lower end of insulating bar is connected with cylindrical rotation input head, the lower end of insulating bar is connected with cylindrical rotation delivery, the axis of input head and delivery and the axis of insulating bar are on same straight line, there is the hexagon section lower end of input head, there is the four prism type groove lower end of input head, there is the annular groove that matches with the pipe of insulating bar the upper end of input head, the axis of the axis of annular groove and four prism type groove and input head cylinder is on same straight line, have on the input head staggered vertical on, following radially pin-and-hole, there is the four prism type plug upper end of delivery, there is the annular groove that matches with the pipe of insulating bar the lower end of delivery, the axis of annular groove and four prism type groove and the axis of insulating bar are on same straight line, have on the delivery staggered vertical on, following radially pin-and-hole, the lower end of insulating bar is inserted in the annular groove of input head upper end, on on the input head, radially the pin-and-hole interpolation has pin rod down, the upper end of insulating bar is inserted in the annular groove of delivery lower end, on the input head on, radially the pin-and-hole interpolation has pin rod down.
The utility model need cooperate electric wrench to use, electric wrench has the sleeve metal plate of electric wrench main frame and supporting a plurality of different sizes, the electric wrench main frame has four prism type rotation delivery, one end of sleeve metal plate has the four prism type jack that matches with the four prism type rotation delivery of electric wrench main frame, and the other end of sleeve metal plate has the hexagonal screw that matches with hex nut.
The four prism type groove of the utility model input head matches with the four prism type of electric wrench main frame rotation delivery, and the four prism type plug of the upper end of delivery matches with the four prism type jack of electric wrench sleeve metal plate one end.
During use, get a sleeve metal plate, the four prism type jack sleeve of sleeve metal plate on the four prism type plug of the utility model delivery upper end, lift the utility model, on the hexagonal screw of sleeve metal plate cover electric device and the hex bolts on the equipment aloft, again the four prism type of electric wrench main frame rotation delivery is inserted in the four prism type groove of input head, start the electric wrench main frame, driving the utility model rotates, and realizes tightening or unscrewing the electric device of eminence and the bolt on the equipment.The utility model also can drive rotation with manual wrench, when driving rotation with manual wrench, the jaw of manual wrench is stuck in the hexagon section of the utility model input head lower end, and the rotation manual wrench realizes tightening or unscrewing the electric device of eminence and the bolt on the equipment.
The four prism type plug of delivery of the present utility model upper end can connect the sleeve metal plate of the plurality of specifications size in the electric wrench, can tighten or unscrew the bolt of plurality of specifications size, and the scope of application is big; The utility model can drive rotation with electric wrench main frame and manual wrench, and is laborsaving, moment of torsion is big.
Below in conjunction with accompanying drawing, the utility model is further described.
