Description
Technical field
The utility model relates to the technical field of stadimeter, specifically a kind of hand-held laser rangefinder.
Background technology
Existing hand-held laser rangefinder 10, as Fig. 1, be all unidirectional metering system, instrument only sends beam of laser.During measurement, appliance requires is against measuring basis A, and the beam of laser sent by instrument aims at testee B, and measuring the measured value obtained is the distance value of measuring basis A to testee B.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of structure simple, easy to use and measure time do not need instrument against the hand-held laser rangefinder of measuring basis.
In order to solve the problem, the utility model provides a kind of hand-held laser rangefinder, comprising: the display be located at the movement one in housing, movement two, master control borad and be located on housing; Described movement one, movement two structure identical and dorsad symmetrical concentricity axle arrange, or arrange dorsad and have angle each other; Movement one comprises: laser tube one, be located at this laser tube one Laser emission end on front side of transmitting mirror one, the reception mirror one being located at this transmitting mirror one side and the dash receiver one be located on rear side of this reception mirror one.Dash receiver in each movement is provided with for receiving laser reflection light to generate the receiving element of corresponding signal, and each receiving element is connected with master control borad.
When the concentricity axle of described movement one, two is arranged, the method of work of above-mentioned hand-held laser rangefinder, comprise: during each movement work, sent the laser of a band phase information through transmitting mirror by laser tube, be irradiated to target back reflection to return, focus on the receiving element of dash receiver through receiving mirror, receiving element generates corresponding signal; Master control borad receives signal that receiving element in each movement generates and according to the phase information in each signal, calculates the spacing of two targets that laser that two movements send irradiates, and shows this spacing by display.
When described movement one, two has angle each other, described method of work comprises: during each movement work, sent the laser of a band phase information through transmitting mirror by laser tube, be irradiated to target back reflection to return, focus on the receiving element of dash receiver through receiving mirror, receiving element generates corresponding signal; Master control borad receives signal that receiving element in each movement generates and according to the phase information in each signal, calculate the spacing of two targets that laser that two movements send irradiates and this laser range finder respectively, then draw the total length of two targets through the line of laser range finder three, and show this length value by display.
The utility model has positive effect relative to prior art: (1) hand-held laser rangefinder of the present utility model, adopt bidirectional measurement mode, it sends the coaxial laser of two beam reversals, do not need instrument against measuring basis during measurement, only two bundle laser need be aimed at measurement target C and D respectively, measuring the measured value obtained is the distance value of C point to D point.(2) advantage that has of the utility model: do not need to look for measuring basis, easy to use, laborsaving; Measure under can completing special occasions easily, as two targets that personnel can not directly arrive; The ranging largest extension one times of unidirectional metering system can be made, and do not need the power improving laser tube.

Embodiment
Embodiment 1
See Fig. 2-4, the hand-held laser rangefinder 10 of the present embodiment, comprising: the display 4 be located at the movement 1 in housing 5, movement 22, master control borad 3 and be located on housing 5.Movement 1, movement 22 dorsad symmetrical, concentricity axle are arranged.
Movement 1 comprises: laser tube one 1-1, be located at this laser tube one 1-1 Laser emission end on front side of transmitting mirror one 1-2, reception mirror one 1-3 being located at this transmitting mirror one 1-2 side and dash receiver one 1-4 be located on rear side of this reception mirror one 1-3, movement 22 comprises: laser tube two 2-1, transmitting mirror two 2-2, receive mirror two 2-3 and dash receiver two 2-4.The structure of movement 22 is identical with movement 1.
During each movement work, sent the laser of a band phase information through transmitting mirror by laser tube, be irradiated to target back reflection and return to focus on the receiving element of dash receiver through receiving mirror.The return signal of two movement dash receivers all passes to the unified process of master control borad 3, calculates the spacing of two targets (C point is to D point) that laser that two movements send irradiates, and shows this spacing by display 4.
Embodiment 2
The method of work of the laser range finder 10 in above-described embodiment 1, comprising: during each movement work, sent the laser of a band phase information, be irradiated to target back reflection and return by laser tube through transmitting mirror, focuses on the receiving element of dash receiver through receiving mirror.The return signal of two movement dash receivers all passes to the unified process of master control borad 3, calculates the spacing of two targets (C point is to D point) that laser that two movements send irradiates, and show this spacing by display 4 according to phase information.
Embodiment 3
On the basis of embodiment 1, there is following modification in the present embodiment:
Movement 1, movement 22 dorsad non-concentricity axle are arranged, but there is an angle (corner dimension is arranged arbitrarily as required); The distance then recorded is the total lengths of two targets through the line of laser range finder three.
The method of work of this hand-held laser rangefinder 10, comprising: during each movement work, sent the laser of a band phase information, be irradiated to target back reflection and return by laser tube through transmitting mirror, focuses on the receiving element of dash receiver through receiving mirror.The return signal of two movement dash receivers all passes to the unified process of master control borad 3, calculates two targets that laser that two movements send irradiates length through the line of laser range finder three, and show this length value by display 4 according to phase information.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.
