Description
Technical field
The present invention relates to a kind of electric insulation bar, particularly a kind of flexible, rotate, self-locking electric insulation bar, belong to the technical field of high-tension electricity work insulating bar aspect.
Background technology
Electric power telescopic insulating bar is very common, but needs design further by rotating the electric insulation bar that just can have self-locking device and inquire into., as brake pull-rod, when carrying out operating a switch operation, often can there is the phenomenon of automatically shrinking, thus have impact on operation of operating a switch in known electric power telescopic insulating bar.The general structure that also can only be designed to three joints, the phenomenon of long automatic contraction can often occur.
Summary of the invention
For the deficiency of above-mentioned technology, the present invention be for solve a kind of flexible, rotate, self-locking electric insulation bar.
A kind of flexible, rotate, self-locking electric insulation bar, comprise, the outer body of rod and the nexine body of rod are all the insulation bodies of rod having certain taper in tubular, it is characterized in that: insert bonding with the outer wall of connecting rod inside major part one end of the nexine body of rod, body of bolt one end is cast in the inner side of connecting rod, the microcephaly of the other end is provided with and tightens up nut, the body of bolt has been threaded six bars, six bars engage with in petal locking head, the outer body of rod and locking head are connected by locking after rotating, the outside of described petal locking head is circular, three petal design shapes that inner side is in the shape of the letter V, flower seam is provided with between every sheet petal, three petal sides are provided with collet, hole is provided with in the middle part of collet, the appearance of six bars is six sided structures and in there being tapering, inner side is provided with screwed hole, screwed hole is threaded with the body of bolt.The outer wall of connecting rod is arranged with the thickness of the nexine body of rod and tapering.In order to make the body of bolt and nut come off, nut check is fixed on the microcephaly of body of bolt one end, and setting concordant with the microcephaly of the body of bolt, the body of bolt other end is in hexahedron structure.
The present invention is easy to use safe and reliable, in use can prevent automatic contraction because being provided with self-locking device, to the work about electric power personnel of operation of carrying out operating a switch, brings conveniently, adds range of choice also to electricity consumption enterprise.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention;
Fig. 2 is the side perspective structural representation of the locking head (7) of Fig. 1;
Fig. 3 is the side perspective structural representation of the body of bolt (3) of Fig. 1, connecting rod (4), six bars (5);
Fig. 4 is that perspective view is looked on the right side of Fig. 2;
Fig. 5 is that perspective view is looked on a left side of Fig. 3.
In figure: the 1 outer body of rod, the 2 nexine bodies of rod, 3 bodies of bolt, 4 connecting rods, 5 six bars, 6 nuts, 7 locking heads, 8 flower seams.
Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the outer body of rod 1 and the nexine body of rod 2 are all the insulation bodies of rod having certain taper in tubular, be plugged in together with the outer wall of connecting rod 4 inside major part one end of the nexine body of rod 2 and bonding firmly, when designing connecting rod 4, the outer wall of connecting rod 4 is arranged along with the thickness of the nexine body of rod 2 and tapering.The body of bolt 3 is provided with screw thread, and the body of bolt 3 one end is cast in the inner side of connecting rod 4, and the other end is provided with microcephaly, and described microcephaly is provided with minor thread, minor thread is provided with and tightens up nut 6.In order to make nut 6 and the body of bolt 3 come off at work, the one end tightening up nut 6 is rounded tiny, and the other end is in hexahedron structure, the concordant setting in screw thread bottom side of rounded tiny one end and the body of bolt 3.The appearance of six bars 5 is six sided structures and in there being tapering, inner side is provided with screwed hole, and screwed hole is threaded with the body of bolt 3.
As shown in Figure 2, Figure 4 shows, locking head 7 is in petal, and described petal outside is circular, three petal design shapes that inner side is in the shape of the letter V, are provided with colored seam 8, three petal sides and are provided with collet between every sheet petal, in the middle part of collet, be provided with hole, every sheet petal is because having colored seam 8 so have by compression elasticity.
As shown in Figure 1, be engaging structure with the tapering six sided structures that has of six bars 5 inside three petal design be in the shape of the letter V, when engaging, the body of bolt 3 is through the hole in the middle part of locking head 7 collet, inside three petal design six of tapering bars 5 being entered into be in the shape of the letter V, when externally the body of rod 1 rotates hand-held the nexine body of rod 2 of people there is pressure and tighten in locking head 7 and six bars 5, thus three petal design of locking head 7 are expanded, locking head 7 and the outer body of rod 1 are locked.
