Abstract
The utility model relates to a tool for examination and maintenance of outdoor electric power facilities, in particular to a telescopic insulating rod, which comprises an insulating bar and an operating head installed at the upper end of the insulating bar. The insulating bar consists of a section of outer pipe and a plurality of sections of inner pipes inserted inside the outer pipe, the inner pipe can be extended or contracted from the outer pipe positioned on the outer layer of the inner pipe or the inner pipe, and the operating head is installed at the upper end of the inner pipe on the innermost layer. The telescopic insulating rod can be contracted to a shorter length by virtue of the arranged the telescopic insulating bar to remarkably reduce the occupied space, resulting in convenience for outdoor carrying. Meanwhile, the when the sections of pipes are extended, the positioning is reliable and the operation is convenient.
Description
Technical field
The utility model relates to a kind of maintenance and operation tool of outdoor power equipment, specifically is a kind of telescopic link rod.
Background technology
Link rod be with a kind of at the instrument that electric power facility is overhauled, often use in the maintenance and operation process, it generally comprises one section insulating bar and is installed in the operating head of insulating bar upper end.By standing in the hand-held insulating bar of ground operating personnel, the electric power facility that is positioned at the high-altitude is operated in the use with operating head.In order to satisfy instructions for use, insulating bar need have enough length.Because whole link rod length is longer, more small-sized engineering vehicle is difficult to shipment, and it is very inconvenient to carry when going out to construct.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of simple in structure, adjustable length, easy to carry, the reliable telescopic link rod of operation are provided.
Telescopic link rod of the present utility model is made up of insulating bar and operating head, described insulating bar is made up of one section outer body and the plurality of sections internal layer body that is inserted in the outer body, the internal layer body can be flexible from being positioned at its outer field outer body or internal layer body, and operating head is installed in the internal layer body upper end of innermost layer.
The lower end of each root internal layer body is connected with a landing nipple, this landing nipple one side has dowel hole radially, it is thick and the alignment pin of the stepped cylindrical that outboard end is thinner is provided with the compression spring between the bottom of alignment pin medial extremity and dowel hole to be mounted with a medial extremity in dowel hole; In addition, be provided with positioning jack in the tube wall of outer body that is positioned at an inner layer pipe volume surrounding or internal layer body upper end, the outboard end of above-mentioned alignment pin can insert positioning jack and the medial extremity of alignment pin can not insert positioning jack.
The utility model can be contracted to it short length owing to be provided with telescopic insulating bar, has significantly reduced taking of its space, and going out, it is easy to carry to construct; The location was reliable, easy to operate when its each section body stretched out simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of internal layer body lower end and outer body upper end positioning states.
Embodiment
As shown in the figure, the insulating bar 1 of this adjustable link rod is made up of outer body 2 and the internal layer body 3 that is inserted in the outer body, and operating head 5 is installed in the upper end of internal layer body 3.Internal layer body 3 lower ends are connected with a landing nipple 6, this landing nipple one side has dowel hole 7 radially, it is thick and the alignment pin 8 of the stepped cylindrical that outboard end is thinner is provided with between the bottom of alignment pin 8 medial extremitys and dowel hole 7 and compresses spring 9 to be mounted with a medial extremity in dowel hole; In addition, be provided with positioning jack 10 in the tube wall upper end that is positioned at an internal layer body 3 outer field outer bodys 2 or internal layer body 3.When an internal layer body 3 extended outward to extreme position, the outboard end of the alignment pin 8 of internal layer body lower end can insert in the positioning jack 10 (as shown in Figure 2) under the elastic force effect of stage clip 9, made two sections bodys obtain the location at the extended position place.
