Abstract

The utility model relates to a measurement device and especially relates to a measurement device for positioning electronic box perforation and laying pipelines. The measurement device is characterized in that a small segment at the top of an aluminium ruler is bent and is used for holding the edge of an electronic box firmly and positioning the aluminium ruler; a hole is formed at a certain distance from the top and is used as a datum line hole (2) and used for drawing a common datum line (6) of edges of holes formed in the electronic box; a plurality of small holes (5) are formed at a segment under the datum line hole (2) and used for positioning perforation spots (8) on the electronic box, and have preset values of distance to edge and inter-spacing; and one side of the aluminium ruler is of a sawtooth type (3), each sawtooth recess point (3) is marked with a dimension corresponding to the perforation size of the electronic box and is used for positioning holes of dimensions of 1/2 '', 3/4'', 1 '', 2 '', 3 '', 4 '' and the like on the datum line, and a distance between the sawtooth recess points is a preset value. The aluminium ruler is advantaged in that a user is not needed to use many tools or calculation to determine perforation positions and the aluminium ruler is convenient and rapid.

Description

Electronic box perforate aluminium chi

Technical field:

The utility model relates to a kind of measurement apparatus, particularly relates to a kind of a kind of measurement apparatus of locating electronic box perforate and tubing.

Background technology:

In the power industry work progress, above often need on electronic box, punching and the pipeline of multiple size being connected to, the track laying after being used for.And do not have at present in the industry special instrument locate perforate on the electronic box the position and the order, all be to use conventional common metric device measuring and locating holes position in the practical operation, as for the arrangement and the spacing in the big or small hole of difference, all need artificial calculating and in-site measurement to locate.The narrow and small local on-the-spot calculating and measure very inconvenient in the space also can exist and calculate or measure inaccurate risk.

Summary of the invention:

Technical problem to be solved in the utility model provides a kind of measurement apparatus at electronic box perforate layout and location of specialty, the method that pre-sets is arranged and do not need operating personnel's measurements and calculations, and is easy to operate and quick.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of aluminium chi, and a bit of bending in top is used to tangle the stable and location aluminium chi in electronic box edge; Have a square hole apart from the top certain distance, this hole is used for the common datum line of picture verge of opening as the datum line hole; The datum line hole has a plurality of small sircle holes toward next section, is the value that presets apart from limit and mutual spacing, is used to locate the central point of electronic box perforate; The aluminium chi is sawtooth pattern on one side, and each sawtooth depression points is put on a size, and corresponding electronic box perforate size is used for finishing back 1/2 at datum line ", 3/4 ", 1 ",

2 ",

3 ",

4 " location in the hole of different sizes such as grade, the distance between the sawtooth depression points is the value that presets.

Compared with prior art, the utlity model has following advantage:

1. it is convenient to draw datum line.Only the bending edges on aluminium chi top need be hung over the electronic box edge, the datum line position is promptly definite, does not need the user to go to measure with chi.

2. location, the hole of different sizes is convenient.Only need be with the toothed edge alignment fiducials line of aluminium chi, perforate size is as required chosen the corresponding sawtooth depression points of marking this size, writes down at the datum line subscript to get final product.

3. the perforate centralized positioning is convenient.Only this end on aluminium chi top need be hung over the electronic box edge, the datum line hole is aligned in the perforate mark of label on the datum line, find the hole of corresponding perforate size above the aluminium chi, get final product with tapping.

4. more than the combination, the user does not need multiple instrument or calculates and can determine position of opening, and is convenient and swift.

Description of drawings:

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1: synoptic diagram of the present utility model

Fig. 2: operation steps synoptic diagram of the present utility model

1. aluminium chi bending edges among the figure, 2. datum line hole, 3. toothed edge, 4. sawtooth depression points, 5. aperture, 6. datum line, 7. gauge point on the datum line, 8. tapping point

Embodiment:

1. aluminium chi bending edges (1) is colluded on one side at electronic box, with pen point in datum line hole (2), then with aluminium chi and pen simultaneously a level remove to another side, a datum line 6 draws on electronic box.

2. with toothed edge (3) alignment fiducials line (6), select an initial position of opening to write down earlier at the datum line subscript, select the corresponding sawtooth depression points of marking this size according to the size of this gauge point (7) perforate then, aim at, as reference point, want the size of perforate also to find the corresponding sawtooth point of marking this size according to the next door then, equally under the datum line mark, it is gauge point (7) on second datum line, go toward the next door again, then the point (7) with second mark is a reference point, locatees next gauge point (7), and the like operation.

3. once more aluminium chi bending edges (1) is colluded on one side at electronic box, datum line hole (2) are aligned on the electronic box gauge point (7) on the datum line, according to the aperture of marking corresponding size on the pairing perforate size of the point that mark is good on the datum line selection aluminium chi, mark, and as the center of circle, i.e. tapping point (8).Operation successively.

Claims (2)

1. electronic box perforate aluminium chi is characterized in that: have a datum line hole (2) apart from the top certain distance, datum line hole (2) have a plurality of apertures (5) toward next section, are the value that presets apart from limit and mutual spacing, are used to locate the central point of electronic box perforate; The aluminium chi is sawtooth pattern (3) on one side, and each sawtooth depression points (4) is put on a size, and corresponding electronic box perforate size is used for finishing back 1/2 at datum line ", 3/4 ", 1 ",

2 ",

3 ", 4 " location in the hole of different sizes such as grade, the distance between the sawtooth depression points (4) is the value that presets.

2. aluminium chi according to claim 1 is characterized in that: a bit of bending in top (1) is used to tangle the stable and location aluminium chi in electronic box edge.
