Abstract
The invention relates to a plumb bob with laser guidance. The plumb bob comprises a conical bob body and a bolt installed at the central position of the upper end face of the conical bob body. The central line position inside the cone is provided with a laser cavity of which the lower end is provided with a light emitting hole which is right at the conical tip position of the cone. The laser cavity is internally provided with a laser in a matching way and an illuminant end of the laser is downward near the position of the light emitting hole. The plumb bob with laser guidance still adopts the characteristic that a plumb bob is downward vertical due to the generation of gravity and simultaneously uses laser guidance to measure verticality without long-distance setting-out of wires. Besides, part of the conical tip of the cone can be reserved, consequently the light emitting hole is at one side of the conical tip, the position of conical point projection (i.e. vertical point) can be determined through the edge or edge center of a lighting area of the laser guidance in a long distance. The plumb bob has simple structure, convenient use, high measurement efficiency and measurement accuracy and is very beneficial to popularization and implementation.
Description
One, technical field:
The present invention relates to the testing tool that a kind of building field uses, particularly relate to a kind of ceiling hammer with laser guide.
Two, background technology:
At present, the ceiling hammer of selling on the market all is the solid ceiling hammer of casting reprocessing.It is directly or indirectly with the fixing upper end of messenger wire of hand, hammer under action of gravity vertically downward, with the verticality of definite other object, metope etc.The survey instrument of this definite verticality is subjected to artificial and environment (wind etc.) influences bigger, ceiling hammer needs one to have and swing to static transit time, because ceiling hammer needs the very long distance of unwrapping wire to measure usually, long more its duration of oscillation of unwrapping wire is also long more, always efficiency of measurement is very low, and operation neither be very convenient.In addition, existing ceiling hammer function is more single, can only the measuring vertical degree, and the levelness of the horizontal direction of Measuring Object simultaneously.
Three, summary of the invention:
The present invention overcomes the deficiency that prior art exists, and designs and produce a kind of ceiling hammer with laser guide.
Technical scheme:
A kind of ceiling hammer with laser guide, comprise conical hammer body, be installed in the bolt of center, conical hammer body upper surface, position of center line in the cone inboard is provided with a laser cavity, this laser cavity lower end is provided with the awl point position that light hole is positioned at cone just, mates the luminous end that a laser instrument and laser instrument are installed and be positioned at downwards near the light hole position in described laser cavity.Utilize this scheme when the verticality of buildingss such as Measuring Object, metope, need not ceiling hammer very unwrapping wire to bottom surface, only determine that by the laser projection behind an amount of unwrapping wire awl spot projection is the position of vertical point, as area of illumination is a circle, then bore spot projection (vertical point) and be circular home position, measure rapidly accurately.
The lower end of described cone is reserve part reference cone point still.One of purpose of reserve part reference cone point is still to keep the effect that former ceiling hammer has the awl point, thereby still has the measurement function of common ceiling hammer; Two of its purpose is to be very easy to determine awl spot projection place according to the shape of area of illumination, thereby forms a prompt judgement position vertically more.Can the awl point and the light hole of cone be determined in specific ratio or shape according to the needs of actual design or application.For example: the ratio of described cone awl point and light hole greater than, equal, less than 1, make the awl point be positioned at the edge of light hole, thereby guarantee that its projection is positioned at the edge of area of illumination, is convenient to rapid judgement.
On described cone, be horizontally installed with at least one laser instrument on the conical surface or in the conical taper sidewall.Common described horizontal laser should the symmetry, be uniformly distributed on the conical surface or the conical taper sidewall in.Wherein each laser instrument extended line is through the cone center, and promptly each laser instrument is outwards dispersed distribution along the cone center.Perhaps each laser instrument extended line is without the cone center.
Beneficial effect of the present invention:
1, the ceiling hammer of band laser guide of the present invention, still adopt ceiling hammer because of gravity generation characteristics downward vertically, utilize laser guide simultaneously, can make ceiling hammer when not needing length, get final product the verticality of Measuring Object, metope etc. apart from unwrapping wire, it is rapidly convenient to measure, and effective.
2, the ceiling hammer of band laser guide of the present invention, the also awl point of reserve part cone simultaneously, thus light hole is positioned at the sharp side of awl, and the existence of awl point does not influence ceiling hammer and uses in normal way.Also can be in that at a distance the edge or the edge center point of the area of illumination by laser guide determine to bore spot projection (being vertical point) position.
3, the ceiling hammer of band laser guide of the present invention not only can be used for the verticality of measuring vertical object, metope etc. and the levelness that can come Measuring Object or buildings by the laser instrument of installation level on circular conical surface or sidewall.
4, the ceiling hammer of band laser guide of the present invention is simple in structure, and is easy to use, the efficiency of measurement height, and the measuring accuracy height is beneficial to promotion and implementation very much.
