Abstract
The utility model relates to a portable height measuring rule for electric power appliance, which comprises a plurality of nested insulating sleeve (1) with uneven diameters and sliding relatively each other, wherein, on the sleeve a dimension line (3) is arranged. The utility model is able to be contracted into a stub tube and drawn out one section after another when in use for measuring height of electric power appliance, thereby having the advantages of being convenient for carryover, simple in operation and suitable for common worker.
Description
Technical field the utility model relates to a kind of survey instrument, promptly a kind of portable power facility height measuring device.
Background technology needs to understand the height of facility often in the operation and maintenance process of electric power facility.For example: when climbing electric post, need know the height of electric post, with correct judgement buried depth, thus the generation of avoiding mistake to step on the casualty accident of falling the bar.In order to guarantee that tall and big carrier vehicle safety by striding the road electric wire, need make regular check on the height of striding the road electric wire, or the like.At present, the instrument of observed altitude is a lot, and, these instruments are the more complicated costliness all, and operation inconvenience often needs the professional and technical personnel, uses under certain conditions.The height of electric power facility then needs to observe anywhere or anytime understanding, and the common line surfaceman runs into this problem through regular meeting in routine duties, thereby existing instrument does not satisfy the needs of real work.
The summary of the invention the purpose of this utility model provides a kind of being easy to carry, portable power facility height measuring device easy and simple to handle.
Above-mentioned purpose is realized by following technical scheme: this portable power facility height measuring device is by a plurality of thickness differences, and is nested together, and the sleeve pipe that can slide relatively constitutes, and is provided with dimension line on sleeve pipe.
Said sleeve pipe all is the taper insulation tube that a kind of two ends diameter does not wait, and in adjacent two branch casings, the small end internal diameter of the big end external diameter of cover sleeve pipe inside and the sleeve pipe of outside is an interference fit.
Said sleeve pipe all is the insulation pipe of a kind of two ends equal diameters, in adjacent two branch casings, the terminal outside of cover sleeve pipe inside is provided with outer bulge loop, the cover pipe orifice front end of outside is provided with internal projecting ring, the diameter of the aperture of outside sleeve pipe and the outer bulge loop of the inside sleeve pipe is for being slidingly matched, and the internal diameter of the internal projecting ring of the external diameter of the inside sleeve pipe and outside sleeve pipe is for being slidingly matched.
In the middle of the said sleeve pipe, the front end of the sleeve pipe in the inside links to each other with a discoid Ka Gai, and the peripheral invagination of Ka Gai is circular, is provided with internal thread in the ring, and matches with external thread outside the outermost layer sleeve pipe front end.
In the middle of the said sleeve pipe, the end of the sleeve pipe in the inside is connected to the flexible cord of band scale, and flexible cord is coiled in the rotating shaft of sleeve pipe back.
Adopt the portable power facility height measuring device of such scheme, be punctured into a short tube at ordinary times, extractions that save land of time spent one joint one can be measured the height of electric power facility, is easy to carry, and be simple to operate, is suitable for common laborer's use.
Description of drawings embodiment of the present utility model is provided by the following drawings.
Fig. 1 is the front view of first kind of embodiment;
Fig. 2 is the left view of first kind of embodiment;
Fig. 3 is the deployed condition synoptic diagram of first kind of embodiment;
Fig. 4 is the front view of second kind of embodiment;
Fig. 5 is a working state schematic representation.
Among the figure as seen: sleeve pipe 1, the card cover 2, dimension line 3, external thread 4, internal thread 5, outer bulge loop 6, internal projecting ring 7.
Embodiment is introduced three kinds of embodiment below in conjunction with accompanying drawing.
First kind of embodiment: as Fig. 1,2, shown in 3, this portable power facility height measuring device is to be made of a plurality of sleeve pipes that are nested together (1) that the fiberglass of high-insulation is made, sleeve pipe all is the thin tapered tube of the thick end of an end, between adjacent two sleeve pipes (1), the front inner diameter of the sleeve pipe (1) of outside is less than the rear end external diameter of the inside sleeve pipe (1), the outside of sleeve pipe is printed on dimension line (2), the front end of innermost sleeve pipe (1) connects a discoid Ka Gai (2), be an annulus on Ka Gai (2) periphery, internal thread (5) is arranged in the annulus, match with the external thread (4) of outer tube (1) front end.At ordinary times, all sleeve pipes all are nested together, and Ka Gai (2) tightens with outmost sleeve pipe (1) front end, thereby makes each sleeve closure inside, so that carry.During use, as shown in Figure 5,, upwards lift top, above Ka Gai (2) is stuck in, can understand the height of facility after stretching by the dimension line (3) above the sleeve pipe to tested facility a section extraction of sleeve pipe (1).
Second kind of embodiment: as shown in Figure 4, this portable power facility height measuring device also is to be made of the multilayer sleeve (1) that the fiberglass of high-insulation is made, and the diameter of each sleeve pipe (1) dwindles successively, is nested together.Different with first kind of embodiment is, these sleeve pipes (1) all are straight tubes, between adjacent two sleeve pipes, be provided with internal projecting ring (7) in the front tube of outside sleeve pipe, the outside, rear end of the inside sleeve pipe is provided with outer bulge loop (6), and the internal diameter of internal projecting ring (7) and the external diameter of the inside sleeve pipe are for being slidingly matched, the external diameter of outer bulge loop (6) and the internal diameter of outside sleeve pipe are for being slidingly matched, when sleeve pipe is pulled out, offset with the inside and outside bulge loop (6) of adjacent casing and (7) and to exceed, can not disconnect.
The third embodiment: its agent structure is identical with preceding two examples, just connects the cord of a softness at innermost sleeve pipe tail end, and cord is moved the cover tube outside to, be coiled in the rotating shaft, when cord is pulled out,, just known the height of measured object by the sizing on the cord.
