Abstract
A telescopic electrical insulation rod capable of rotating and achieving self locking comprises an outer rod body (1) and an inner rod body (2), wherein the outer rod body (1) and the inner rod body (2) are both cylindrical insulation rod bodies with certain conical degrees. The electrical insulation rod is characterized in that the inner side of a large end of the inner rod body (2) is bonded with the outer wall of a connecting rod (4) in an inserted mode, one end of a bolt body (3) is cast on the inner side of the connecting rod (4), a fastening nut (6) is arranged at a small end of the bolt body (3), a six-face rod (5) is connected on the bolt body (3) in a threaded mode, the six-face rod (5) is meshed with a petal-shaped locking head (7), and the outer rod body (1) is connected with the locking head (7) in a locked mode through rotating. The outer wall of the connecting rod (4) is arranged along with the thickness and the conical degree of the inner rod body (2). The electrical insulation rod is easy, convenient, safe and reliable to use; when the electrical insulation rod is provided with a self-locking device in use, automatic contraction can be prevented, convenience is brought to electrical operation staff carrying out switch-out operation, and a selection range is increased for electric enterprises.
Description
Technical field
The present invention relates to a kind of electric insulation bar, particularly a kind of flexible, rotation, self-locking electric insulation bar, belong to the technical field of high-tension electricity work by the insulating bar aspect.
Background technology
Electric power telescopic insulating bar is very common, but can need further design by the electric insulation bar that rotates, just can have self-locking device and inquire into.The phenomenon of automatically shrinking, as brake pull-rod, when being operated a switch operation, often can occur, thereby affect the operation of operating a switch in known electric power telescopic insulating bar.Generally also can only be designed to the structure of 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 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) is all to be the insulation body of rod that tubular has certain taper with the nexine body of rod (2), it is characterized in that: at the inboard outer wall with connecting rod (4) of the large first end of the nexine body of rod (2), insert bonding, 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), six bars (5) have been threaded on the body of bolt (3), 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, and 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 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, at the collet middle part, is provided with hole.
The present invention is easy to use safe and reliable, in use because being provided with self-locking device, can prevent automatic contraction, gives the work about electric power personnel of the operation of being operated a switch, and has brought convenience, has increased range of choice also to electricity consumption enterprise.

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 flowers stitch.
Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, the outer body of rod 1 is all to be the insulation body of rod that tubular has certain taper with the nexine body of rod 2, at the inboard outer wall with connecting rod 4 of the large first end of the nexine body of rod 2, be plugged in together also bonding firm, 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 on 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, on described microcephaly, is provided with minor thread, is provided with on minor thread and tightens up nut 6.In order to make at work nut 6 and the body of bolt 3 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, and inboard 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 petal, and described petal outside is circular, three petal design shapes that 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 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, when engagement, the body of bolt 3 is through the hole at locking head 7 collet middle parts, make six bars 5 of tapering enter into three petal design inboards that are in the shape of the letter V, when people's hand is held the external body of rod 1 rotation of the nexine body of rod 2, pressure occurs and tightens in locking head 7 and six bars 5, thereby three petal design of locking head 7 are enlarged, make locking head 7 and the outer body of rod 1 locking.
