Background technique

Laser station meter is the new instrument of engineering survey and deformation observation, and it utilizes laser as collimated radiation, continues Emission Lasers light beam, receives laser singal measure by photelectric receiver.In use, need laser station meter to be arranged on tripod, fall way and sleeve pipe on tripod are made light path, after the laser beam of laser emission point is by fall way and sleeve pipe, in bottom, form a laser-based on schedule.But owing to there being some vagabond rays also can be by fall way and sleeve pipe in light beam, and fall way on tripod and the inwall of sleeve pipe are light wall construction, therefore cannot decay to the energy of vagabond ray, so can affect the quality of laser imaging, thus have influence on laser-based precision on schedule.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, can improve intensity, and reduce the laser device tripod of vagabond ray to laser imaging quality.

The utility model is that the technological scheme achieving the above object is: a kind of laser device tripod, comprise runners, be hinged on the foot stand mechanism of three foot levers formations on runners and be arranged on the elevator mechanism on runners, described elevator mechanism comprises for controlling the self-locking driving mechanism of fall way lifting and being arranged on the fall way in runners, and runners bottom is provided with sleeve pipe, fall way is arranged in sleeve pipe and can moves up and down, it is characterized in that: described fall way tube wall is provided with the first wave shape wave surface that vagabond ray energy is decayed, the tube wall of described sleeve pipe is provided with the Second Wave shape wave surface that vagabond ray energy is decayed.

The tube wall of the fall way of the utility model on tripod and the tube wall of sleeve pipe are provided with the first and second waveform surfaces that vagabond ray energy is decayed, therefore can lead to by change the geometric shape of light fall way inwall and internal surface of sleeve pipe, make fall way and sleeve pipe can form specific logical light inwall, therefore when the logical fall way of laser beam and sleeve pipe, can to the vagabond ray energy in light beam, decay by the waveform surface on inwall, therefore can effectively control the impact of vagabond ray on laser imaging quality, guarantee laser-based precision on schedule.The utility model is provided with waveform surface in fall way and sleeve pipe, makes to form vertically rib strip shaped in fall way and sleeve pipe, therefore can also improve the intensity of fall way and sleeve pipe, can alleviate the weight of tripod.
