Description
Technical field
The present invention relates to surveying instrument field, particularly relate to a kind of stadimeter of hand-held.
Background technology
In recent years, laser ranging method is widely used in the measurement of distance, and laser range finder also becomes the important tool of range observation, its principle launches a pulse signal by a generating laser to object, again by a low noise, high sensitive laser pickoff receives the signal reflected by this object, the reflected signal utilizing this to receive can calculate the distance of object, its principle can by formula: L=Td*C/2 represents, wherein, L is the distance of object to be measured, Td is transponder pulse signal and return pulse signal time delay between the two, C is light velocity of propagation, only need measure Td time delay, then the distance L of object to be measured can obtain.Produce laser range finder according to this principle, especially hand-held laser rangefinder, because its volume is little, lightweight, precision is high, and especially building trade is extensively used in the measurements, deeply favors by user.
In prior art, also there is following defect in the stadimeter of hand-held: the housing of (1) lens mount and stadimeter is integral structure, in the production technology of stadimeter, be secured on lens mount owing to needing to carry out playing glue after eyeglass installation, play the eyeglass after glue to need to place considerable time and be dried to and be completely fixed, the processing of the follow-up each technique of stadimeter can be had a strong impact on, thus greatly reduce the production efficiency of stadimeter, in addition, housing precision prescribed is high, and production cost is high, and lens mount is integral type structure for housing relatively, and lens mount cannot be replaced according to model, and housing can not be general, poor for applicability, thus substantially increase manufacturing cost, (2) existing mainboard is all that one end is directly fixed on housing, outside covers enclosing cover again, due to the structure that mainboard is strip, unbalance stress can be there is, yielding, mainboard is the part of stadimeter core the most, and the precision that the distortion of mainboard or damage can badly influence measurement even stadimeter cannot be measured, in addition, the installation of mainboard is directly installed on housing, and around without location, in Long-Time Service, mainboard easily loosens, and display screen is easily dropped, and the precision having influence on measurement further even stadimeter cannot be measured thus have influence on the measurement of stadimeter, (3) inner structure of stadimeter is by upper and lower cover body capping, upper and lower cover body in existing and the inner structure of stadimeter are connected by matching relationship, in Long-Time Service, inner structure can relative upper and lower cover cognition be rocked, structure built on the sand, thus has influence on the precision of measurement, (4) when carrying out the installation of element, because the installation accuracy of transmitter unit and receiving element requires high, especially transmitter unit, in laser range finder, general transmitter unit is laser module, radiative position directly has influence on measurement result, therefore the position of transmitter unit must be accurately, therefore need to carry out adjusting all directions, ensure the accuracy of installing, but in prior art, to the installation of transmitter unit and receiving element, generally that transmitter unit and receiving element are pushed into corresponding installation cavity from housing posterior transversal, trouble is installed, be pushed into installation cavity from sidepiece, the adjustment of front and back position can only be carried out, up and down, right position adjustment and inconvenience thereof even cannot adjust, thus the installation accuracy of transmitter unit and receiving element cannot be ensured.
