Abstract
The utility model relates to a laser bolt. The inside of the bolt is provided with a hollow cavity, and the inside of the hollow cavity of the bolt is provided with a laser transmitter. During use, the laser bolt is screwed in a connection hole of a theodolite. The laser transmitter can send a small red point of a light beam, and a user can conveniently see the alignment condition of the measured point. The utility model has the advantages of higher measurement precision of the theodolite, convenient use, no influence from weather conditions, simple structure, and easy processing and production.
Description
Technical field
The utility model relates to a kind of fixed laser bolt that is used for transit.
Background technology
At present, measure the transit set bolt that uses in the operation, three characteristics are arranged: there is screw thread the bolt upper end, is used for fixing transit; Be provided with cavity in the bolt, by cavity, whether optical centering device eyepiece may observe transit is positioned at survey station dot center; The bolt lower end ball that dangles capable of hoisting.Whether the user aims at the measurement website by the summit that looks round plumb bob, judges whether transit installs.This plumb bob of watching is judged whether mounted method of transit, can be said to be convenient when fine operation, but if meet blow, rain, cloudy, because of light and wind-force, the user just is difficult to see clearly the summit of plumb bob and whether aims at the measurement website.Therefore, be difficult to guarantee measuring accuracy, the operation of also having to abandon sometimes.
The utility model content
Problem to be solved in the utility model is: a kind of Laser bolt is provided, and this Laser bolt is easy to use, and is not subjected to the influence of weather condition, is used for the more convenient operation of survey crew and improves measuring accuracy.
The technical scheme that the utility model provides is: a kind of Laser bolt, be provided with cavity in the bolt, and be provided with generating laser in the bolt cavity.
The beam center of above-mentioned generating laser is coaxial with Laser bolt.
When the utility model uses Laser bolt is screwed in the connecting hole of transit, generating laser penetrates a light beam small red dot, and whether the user can conveniently see measured point clearly and aim at.Thereby it is higher, easy to use and be not subjected to the influence of weather condition and simple in structure, easy processing that the utility model is used for the measuring accuracy of transit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the electrical connection synoptic diagram of generating laser of the present utility model.
Embodiment
Referring to Fig. 1, Fig. 2, be provided with cavity 2 in the bolt 1 of the present utility model, be provided with generating laser 5 in the bolt cavity 2.Generating laser 5 is made of laser crystal 7 and battery 4; The beam center of generating laser 5 is coaxial with bolt.Bolt 1 of the present utility model can be made as upper and lower two parts; Top 3 and bottom 6 are by being threaded; Generating laser 5 is located at bolt bottom 6, can be by 9 loading and unloading of the spiral cover on the bolt bottom 6 of outwarding winding.When the utility model uses Laser bolt 1 is screwed in the connecting hole of transit, open the switch 8 of generating laser 5, generating laser 5 penetrates a light beam small red dot, and whether the user can conveniently see measured point clearly and aim at.
Claims (2)
1. a Laser bolt is characterized in that: be provided with cavity in the bolt, be provided with generating laser in the bolt cavity.
2. Laser bolt according to claim 1 is characterized in that: the beam center of above-mentioned generating laser is coaxial with Laser bolt.
