Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

The utility model provides a day and night dual-purpose centering rod, which comprises a rod body 1, wherein an external thread is formed at the bottom end of the rod body 1, a connecting piece 12 is connected to the bottom end of the rod body 1 through the external thread, the connecting piece 12 is coaxially arranged with the rod body 1, the rod body 1 is connected with a base 2 through the connecting piece, a jack matched with the connecting piece 12 is formed in the base 2, one end, away from the rod body, of the connecting piece 12 is inserted into the jack, so that the base 2 can play a fixed supporting role on the rod body 1, and an external thread is also formed at the top end of the rod body 1, so that the connecting piece is used for being connected with a prism 3 through threads.

The body of rod 1 cavity sets up to body of rod 1 selects transparent PVC material to make, and the inside cover of body of rod 1 is equipped with filament 11, and the top of filament 11 and the top fixed connection of body of rod 1, the bottom of filament 11 and the bottom fixed connection of body of rod 1, and the bottom of filament 11 still electric connection has the power cord, in order to be used for connecting external power source, thereby supplies power for filament 11, makes filament 11 light.

The filament 11 and body of rod 1 coaxial setting, when using the centering rod in night or the weaker environment of light, can light filament 11, and then when utilizing the total powerstation to observe the centering rod, can find the position of centering rod more easily to only need to make the cross silk in the total powerstation aim at filament 11 can realize measuring process, because filament 11 compare with body of rod 1 thinner, so when utilizing the total powerstation to aim at filament 11, its measured data can be more accurate.

The outer diameter of the rod body 1 is set to 25mm, and the lamp filament 11 does not need to be lightened when the lamp is used in the daytime or in an environment with sufficient light, and the lamp filament can be used according to a conventional use method. The diameter of the filament 11 is set to 3mm, so that a centering line with higher accuracy can be provided for the alignment of the total station, the detection accuracy can be higher, and meanwhile, compared with a centering rod with 25mm in the prior art, the accuracy of the filament 1 with 3mm can be higher.

The diameter of the filament 11 is not limited to 3mm, and may be appropriately adjusted according to the use condition, and 3mm is only the minimum diameter of the filament 11.

In summary, the filament 11 is arranged in the rod body 1, so that the centering rod can be normally used at night or in an environment with weak light, and the centering and positioning effects can be realized only by enabling the total station to aim at the light emitted by the filament 11. By setting the diameter of the filament 11 to 3mm, the orientation accuracy can be made higher.
