Abstract

The utility model relates to a detecting device for buried wires. The utility model is composed of a metal wire and a permanent magnet block. The utility model is characterized in that one end of the metal wire is linked with one permanent magnet block at least. When the concrete position of the buried sleeve pipe is detected, one end of the permanent magnet block of the detecting device extends into the buried sleeve pipe, a compass is appressed with the wall surface of the sleeve pipe, the compass is moved, and thus the utility model quickly and accurately judges the concrete position of the buried sleeve pipe through the swing strength of the compass. The utility model has the advantages of simple structure, and convenient use, and solves the problem that the accurate position of the sleeve pipe of the buried pipeline is difficult to find in the existing building operation. The accuracy of detecting and positioning results is high, and the error is little.

Description

The concealed wire pick-up unit

Technical field

The utility model relates to a kind of pick-up unit that detects the concealed piping position, especially a kind ofly is used to detect the concealed wire pick-up unit that secretly is embedded in the pipeline position in the cement concrete floor.

Background technology

Now, in order to beautify household, all pipelines of family, all be mounted in as electric wire, telephone wire, netting twine etc. and be embedded in advance in body of wall or the cement concrete floor, especially cement concrete floor is when the casting floor, because the pipeline sleeve pipe must be pre-buried in advance, therefore the pipeline sleeve pipe often is crushed in work progress, can't be unimpeded when relevant pipeline is installed thereby cause.Run into this situation at present, owing to can't accurately judge, therefore often around the roughly direction of sleeve pipe, seek, bring great difficulty to searching with the reciprocating drill probing by the position of gland pipe; Serious situation, because the probing eyelet is too much, the one-piece construction of havoc body of wall stays great potential safety hazard to the house.

Summary of the invention

In order to solve the problem that can't detect the accurate position of concealed piping at present with simple mechanism, the utility model provides a kind of concealed wire pick-up unit, this installs, and not only structure is simple especially, manipulates easy and conveniently, and can detect the position of judging dark bushing burying effectively and accurately.

The technical scheme that its technical matters that solves the utility model adopts is: this concealed wire pick-up unit, form by metal wire and permanent magnetic iron block, and be connected at least one permanent magnetic iron block at an end chain of metal wire.Because metal wire has good rigidity and elasticity, in the progradation, less metal wire is more conducive to turn in dark bushing burying, and a plurality of permanent magnetic iron blocks of little bulk connect the employing link, also be for the ease of when running into dark bushing burying case of bending, unimpeded smoothly better.When needs detect the sleeve position that secretly is embedded in the cement floor, an end that concealed wire pick-up unit chain is connected to permanent magnetic iron block stretches into from the collar aperture of embedded sleeve joint line box, by the metal wire forward impelling, when running into sleeve pipe and be crushed the position, the metal wire of pick-up unit can't advance, the general direction of burying underground along sleeve pipe, compass with full hyaline test, being close to the cement floor face slowly slides, when compass during near the permanent magnetic iron block of pick-up unit, its pointer is swing fast, and the beat of pointer is strong more, the permanent magnetic iron block position of compass the closer to pick-up unit is described, thereby judges the definite position that dark bushing burying is crushed rapidly.

The beneficial effects of the utility model are:

1, structure is simple especially, manipulates easy and convenient;

2, solved a difficult problem that is difficult to seek the accurate position of dark bushing burying in the present building operation, practical, thus avoid wall body structure destroyed and stay potential safety hazard;

3, detection and location accuracy height as a result, error is little.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the use detected state synoptic diagram that utilizes concealed wire pick-up unit of the present utility model.

Embodiment

In Fig. 1, this concealed wire pick-up unit is made up of iron wire (1) and permanent magnet ball (2), in order to strengthen magnetic, improve the sensitivity that detects, two magnet balls (2) of link are linked at an end of iron wire (1) mutually, magnet piece uses the magnet ball shape, is unimpeded in order to advance in dark bushing burying.

When the detection service sleeve is damaged by pressure the place, the iron wire (1) of hand-held concealed wire pick-up unit, the permanent magnet ball (2) of pick-up unit is put in an end of line box inlet from the sleeve pipe (4) that secretly is embedded in the cement floor (5), firmly permanent magnet ball (2) is pushed away inward, because the quilt place of damaging by pressure passage diminishes and narrows down, permanent magnet ball (2) can't pass through, at this moment with hand compass (3) being close to floor face along dark bushing burying direction slowly moves, when compass (3) near by gland pipe position, it is permanent magnet ball (2) position of pick-up unit, the pointer of compass (3) i.e. is swing rapidly, swings strong more place, be exactly by gland pipe position.

Claims

1. a concealed wire pick-up unit is made up of metal wire (1) and permanent magnetic iron block (2), it is characterized in that an end chain of metal wire (1) is connected at least one permanent magnetic iron block (2).

2. concealed wire pick-up unit according to claim 1 is characterized in that permanent magnetic iron block (2) is the spherosome shape.
