Abstract
The utility model relates to a length measurer, particularly a steel tape being convenient for underground workers of mines, and the utility model is composed of a tape hook, a magnetic steel, a tape band, a locking key, a casing, etc. The magnetic steel is fixed behind the end of the tape band, the front end of the magnetic steel is a magnetic pole face which passes through the tape hook. The utility model can be adsorbed on a ferromagnetic object through the magnetic force of the magnetic steel and can conveniently measure distances of steel objects without angles and edges, such as single-hydraulic props, etc. The utility model avoids inconvenience that common tapes are tensioned by both hands to measure and eliminates the influence of reading accuracy.
Description
The utility model relate to measure length amount its, particularly a kind ofly be convenient to the steel tape that down-hole, mine worker uses.
At present, under coal mine, often need measure the post distance of metal (steel) support, workplace metal individual prop, the gauge of conveying track etc. with steel tape.For resembling the situation of measuring the hydraulic prop distance, measure with existing steel tape, just seem very inconvenient, because it is cylindric, acerous no rib, the chi hook can block nowhere, must with the hands strain measurement, influences the convenience and the accuracy of reading.
Purpose of design of the present utility model is to overcome the weak point in the prior art, and provide a kind of down-hole, mine worker that is particularly suitable for, be used to measure resemble that hydraulic prop etc. is columned, the ferromagnetic object spacing of acerous no rib, the termination of chi band has the steel tape of magnetic force.
Purpose of design of the present utility model can reach by following measure:
In hold up the steel tape that button 4, housing 5 constitute by chi hook 1, chi band 3, lock, at the back side of the termination of chi band 3 magnet steel 2 is installed, the front end of magnet steel 2 passes chi hook 1.
Compared with the prior art the utility model has following advantage:
1. utilize the magnetic force of the magnet steel of steel tape external part termination, be adsorbed on the ferromagnetic object, can measure spacing resemble the hydraulic prop, acerous no rib, iron and steel rounding columnar object easily.Thereby avoided with the hands tension to measure, eliminated influence the convenience and the accuracy of reading.
2. make simple.
The drawing of accompanying drawing is described as follows:
Fig. 1: the utility model structural representation front view
Fig. 2: A is to view
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1,2: show structure of the present utility model.It by chi hook 1, magnet steel 2, chi band 3, lock is held up button 4, housing 5 constitutes.Magnet steel 2 is a rectangular thin plate, is positioned at the end of its chi band 3, is close to the back side of chi band 3, and the front end face M of magnet steel 2 is a pole surface, and the front end of magnet steel 2 passes chi hook 1, so that be adsorbed on the ferromagnetic object by it.For this reason, will open corresponding hole on the chi hook 1, housing 5 forward (FWD) mouths also should suitably be thickeied.Because of magnet steel 2 volumes are little, easily select the high permanent magnetic material of magnetic property, as Al-Ni-Co permanent magnet, rare-earth cobalt permanent magnet etc.The fixing means of magnet steel can be used the holdfast anchoring, and the magnet steel thin plate need give drilling, also can bond with epoxy adhesive.
Claims (1)
1. be convenient to mining steel tape for one kind, have chi hook (1), chi band (3), lock to hold up button (4), housing (5), it is characterized in that at the back side of chi band (3) termination one magnet steel (2) being housed, the front end of this magnet steel passes chi hook (1).
