Description
Technical field
The utility model relates to a kind of prism bar, belongs to technical field of measuring equipment.
Background technology
Prism is surveying instrument conventional in engineering survey, but in the underground pipe gallery of dark, on the through street at night, and other do not throw light on or dim light condition under, surveying instrument observation personnel often cannot find out the accurate location of traditional measurement bar accurately, thus result in a large amount of wastes of time and personnel, and because survey crew is in continuous movement when night measures, common safety alarm device can not provide effective safe warning function to survey crew; Meanwhile, because the construction of the new period is had higher requirement to the precision measured, common prism cannot meet high-precision requirement in certain circumstances, and no prism leveling is owing to being taken measurement of an angle, and the impact such as reflection strength has some limitations.
Summary of the invention
The purpose of this utility model under the poor condition of light, uses inconvenient safe warning function difference affect the problem of measuring accuracy in order to solving in prism measuring process, provides a kind of structure simply, prism bar compact to design.
The utility model adopts following technical scheme: a kind of prism bar, described prism bar comprises sheathed mobile jib and pole, described pole is sheathed in mobile jib, the upper end of described mobile jib is provided with draw-in groove, the lower end of described pole is provided with dop, described dop and draw-in groove mate mutually can make pole be fixedly connected with mobile jib, the upper end of described pole is provided with prism bayonet socket, described prism bayonet socket is provided with prism head, the top of described prism head is provided with reflective card holder, described reflective card holder is provided with reflecting piece, the upper end of described mobile jib is provided with leveling bubble, the lower end of described mobile jib is provided with nose cone, described mobile jib and pole are arranged at intervals with several LED respectively.
Further, described reflective card holder comprises pedestal, described pedestal is welded on prism head, described impact faces arranges the first metal intermediate plate and the second metal intermediate plate, space is provided with for placing reflecting piece in the middle of described first metal intermediate plate and the second metal intermediate plate, described first metal intermediate plate is provided with clamping screw, and described clamping screw is used for reflecting piece to be fixed in the space of the first metal intermediate plate and the second metal intermediate plate.
Further, be provided with the first battery case inside described mobile jib, described first battery case is connected with the LED on mobile jib by circuit, is provided with the second battery case inside described pole, and described second battery case is connected with the LED on pole by circuit.
Further, the lower end of described mobile jib is provided with retaining thread and is connected with nose cone.
The utility model structure is simple, compact to design, easy to use, cost is lower, the setting of the LED on mobile jib and pole can make prism bar use normally under the poor condition of light, and the effect of security warning can be played to survey crew, effectively can coordinate when high-acruracy survey and carry out high-acruracy survey without prism.
