Abstract
The utility model discloses a laser centering device, which comprises a centering bolt, a laser transmitter and a battery. The upper end of the centering bolt is provided with a screw stem, a vertical shaft inside the centering bolt is provided with a mounting cavity axially, the laser transmitter and the battery are disposed inside the mounting cavity, a sliding switch used for controlling on or off between the laser transmitter and the battery is disposed outside the mounting cavity, and the bottom of the centering bolt penetrates through the bottom of the mounting cavity to form an injection hole. The bottom of the screw stem is provided with a mounting hole, and a connecting pin is screwed into the mounting hole to fix the screw stem. The laser centering device can fast realize centering primarily through injecting light beams emitted by the laser transmitter from the injection hole, and then large quantities of measuring instruments without laser centering devices can conveniently realize laser centering in low cost. Due to action of the connecting pin, the laser centering device can be detached, maintained and corrected conveniently, can greatly reduce volume, brings more convenience for users to operate, and is simple in structure, convenient and practical in use, low in cost and fine in centering effect.
Description
Technical field
The utility model laser alignment device belongs to the engineering survey field.
Background technology
Existing surveying instrument centering is adopted common eyepiece observation mostly, and use is numerous and diverse, and occurs artificial unavoidable error extremely easily in operating process, under the situation of insufficient light, also can't measure, as: tunnel, culvert, mine etc.Existing centering instrument body is long-pending too huge, and the inner structure complexity is inconvenient to dismantle maintenance and maintenance.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned defective of prior art, a kind of dismounting, maintenance and correction convenience, volume laser alignment device little and with low cost are provided.
The utility model is realized by following scheme: comprise centering bolt, generating laser and battery, the upper end of centering bolt is a screw rod, the inner vertical pivot of centering bolt axially has installation cavity, generating laser and battery are arranged in the installation cavity, installation cavity is equipped with the slide switch that is switched on or switched off battery in order to the control generating laser outward, the installation cavity bottom is run through centering bolt bottom and is formed the ejaculation hole, and generating laser emission light penetrates by penetrating the hole.
The screw rod bottom of centering bolt described in the utility model has a mounting hole, fixes by connecting in the pin screw-in mounting hole.
The utility model can penetrate from penetrating the hole by light beam that generating laser sends, and can carry out preliminary centering fast, and this can make things convenient for and cheap realization laser alignment for the surveying instrument that does not possess the laser alignment device in a large number.Because the effect of the pin of connection is arranged, can dismantle easily, keep in repair and proofread and correct, and reduce the volume of instrument greatly, be more convenient for the user to operate.The utility model is simple in structure, convenient and practical, with low cost, centering is effective.
