Abstract
A telescopic, rotary and self-locking electric insulating rod comprises an insulating rod body with a certain taper, wherein an outer rod body (1) and an inner-layer rod body (2) of the insulating rod body are cylindrical. The telescopic, rotary and self-locking electric insulating rod is characterized in that the inner side of a large-head end of the inner-layer rod body (2) is bonded with the outer wall of a connecting rod (4) in an insertion mode; one end of a bolt body (3) is cast at the inner side of the connecting rod (4) and a small head on the other end is provided with a fastening nut (6); the bolt body (3) is in threaded connection with a six-sided rod (5), and the six-sided rod (5) engages with a petal-shaped locking head (7); and the outer rod body (1) and the locking head (7) are in locked connection through rotation. The outer wall of the connecting rod (4) is arranged according to thickness and taper of the inner-layer rod body (2). The telescopic, rotary and self-locking electric insulating rod is simple and convenient to use and safe and reliable, can be prevented from automatically contracting during use due to the arrangement of a self-locking device, brings convenience to electric workers carrying out power switching-off operations and expands the scope of selection for power utilization enterprises.
Description
Technical field
The utility model relates to a kind of electric insulation bar, and particularly a kind of flexible, rotation, self-locking electric insulation bar belong to high-tension electricity work with the technical field of insulating bar aspect.
Background technology
Electric power telescopic insulating bar is very common, but can need by the electric insulation bar that rotates, just can have self-locking device further design and discussion.Automatically the phenomenon of contraction such as brake pull-rod, when operating a switch operation, often can occur, thereby affect the 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.
The utility model content
For the deficiency of above-mentioned technology, the utility model is for solving a kind of flexible, rotation, self-locking electric insulation bar.
A kind of flexible, rotation, self-locking electric insulation bar, comprise, the outer body of rod (1) all is to be the insulation body of rod that tubular has certain taper with the nexine body of rod (2), it is characterized in that: insert bonding at the inboard outer wall with connecting rod (4) of the large first end of the nexine body of rod (2), the microcephaly that the body of bolt (3) one ends are cast in the inboard other end of connecting rod (4) is provided with and tightens up nut (6), at the body of bolt (3) six bars (5) that have been threaded, six bars (5) be the engagement of petal locking head (7), the outer body of rod (1) is connected by rear locking of rotation with locking head (7).The outer wall of connecting rod (4) is with thickness and the tapering setting of the nexine body of rod (2).For nut (6) and the body of bolt (3) should not be come off, an end that tightens up nut (6) needs the concordant setting in screw thread the bottom side circular tiny and body of bolt (3), and the other end is to be hexahedral ordinary construction.The appearance of six bars (5) is six structures and is tapering is arranged that the inboard is provided with screwed hole, and screwed hole is threaded with the body of bolt (3).Locking head (7) is petal, and described petal outside is circular, and three petal design shapes that the inboard is in the shape of the letter V are provided with flower seam (8) between every petal, and three petal one sides are provided with collet, is provided with the hole at the collet middle part.
The utility model is easy to use safe and reliable, in use can prevent automatic contraction because being provided with self-locking device, gives the work about electric power personnel of the operation of operating a switch, and has brought convenience, has increased range of choice also for electricity consumption enterprise.

Among the 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 flowers stitch.
Embodiment
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the outer body of rod 1 all is to be the insulation body of rod that tubular has certain taper with the nexine body of rod 2, be plugged in together also bonding firm at the inboard outer wall with connecting rod 4 of the large first end of the nexine body of rod 2, when design connecting rod 4, the outer wall of connecting rod 4 is along with thickness and the tapering setting of the nexine body of rod 2.Be provided with screw thread at the body of bolt 3, the inboard other end that the body of bolt 3 one ends are cast in connecting rod 4 is provided with the microcephaly, is provided with minor thread described microcephaly, is provided with at minor thread and tightens up nut 6.For nut 6 and the body of bolt 3 should not be come off, an end that tightens up nut 6 is rounded tiny, and the other end is to be hexahedron structure, the concordant setting in screw thread bottom side of a rounded tiny end and the body of bolt 3.The appearance of six bars 5 is six structures and is tapering is arranged that the inboard is provided with screwed hole, and screwed hole is threaded with the body of bolt 3.
Such as Fig. 2, shown in Figure 4, locking head 7 is petal, and described petal outside is circular, three petal design shapes that the inboard is in the shape of the letter V are provided with 8, three petal one sides of flower seam and are provided with collet between every petal, be provided with the hole at the collet middle part, so every petal is because there being flower seam 8 to have by compression elasticity.
As shown in Figure 1, inboard six structures of tapering that have with six bars 5 of three petal design that are in the shape of the letter V are engaging structure, the body of bolt 3 passes the hole at locking head 7 collets middle part when engagement, make six bars 5 of tapering enter into three petal design inboards that are in the shape of the letter V, pressure and deflation occur in locking head 7 and six bars 5 when people's hand is held the 2 external body of rod 1 rotation of the nexine body of rod, thereby three petal design of locking head 7 are enlarged, make locking head 7 and the outer body of rod 1 locking.
