The carpenter's square that Chinese architecture founder (of a school of learning) master craftsman of the Spring and Autumn period invented in the The Spring and Autumn Period comprises gages such as civilian light chi, the blue chi of fourth and refreshing light chi.Make optimizing planning by the reference carpenter's square for architectural design, to meet the general popular size positions of being expected and accepting of Chinese society.Need in the industry a kind ofly can when predicting size, obtain the range finding product of carpenter's square size equally.

The utility model content

Technical problem to be solved in the utility model provides a kind of laser range finder, its display screen in laser range finder is provided with carpenter's square and indicates body, with the corresponding demonstration of size indication body do that is showing with metric system or English system through the measured distance and position of laser range finder, making laser range finder in carrying out ranging process, can be accurately to record physical size at once.

For solving the problems of the technologies described above, technical solution adopted in the utility model is, a kind of laser range finder, comprise a body, in this body, be provided with a circuit board, be provided with an operating portion, a display screen and a distance sensing device in this body surface, this circuit board is connected to this distance sensing device, this operating portion and this display screen, and this display screen comprises that one first indicates body and one second sign body.

Wherein, the described first sign body is metric system measured value or measured value made in Great Britain, and the second sign body is civilian light chi measured value, the blue chi measured value of fourth or refreshing light chi measured value, and the physical size of the first sign body and the second sign body representative is corresponding.Described operating portion comprises at least one operating key.Described body also is provided with an inclination angle sensor and is connected with circuit board, and display screen comprises that also one the 3rd indicates body.

The beneficial effect that the utility model can reach is, laser range finder that the utility model provides can be built thing etc. or other item sizes for measuring the house, and is easy to use.This laser range finder can obtain the measurement data of common ruler and civilian light chi, the blue chi measured value of fourth or refreshing light chi immediately when using, need not change in addition, has result of use easily.

Embodiment

Please refer to Fig. 1, the utility model provides a kind of laser range finder, include a body 10, this body one side surface is provided with an operating portion 11 and a display screen 12, wherein this operating portion 11 includes one or more operating key, use for pressing operation, this display screen 12 can be watched for the user for the control display image.This body opposite side surface is provided with a distance sensing device 13, this distance sensing device can be launched a ray B along a sensing direction A outside body 10, type difference according to this distance sensing device, this ray may be infrared ray, laser, visible light or other various rays, this ray can in the contact object after resilience, and by the ray after the distance sensing device reception resilience, the distance sensing device produces a distance sensing signal simultaneously.Be provided with an inclination angle sensor 14 and a circuit board 15 in this body, this inclination angle sensor 14 can sense the level inclination of this body 10, and produces an inclination angle sensing signal.This circuit board 15 is connected in this operating portion 11, this display screen 12, this distance sensing device 13 and this inclination angle sensor 14, this circuit board can be according to the pressure-controlled of pressing of operating portion button, start, close or carry out other various operations, this circuit board 15 can be from distance sensing device 13 receiving range sensing signals, and converse corresponding data, this circuit board is distance sensing signal control display screen according to this, shows that one first indicates body and one second sign body.Please refer to Fig. 2, first indicate body 121 be metric system measured value and measured value made in Great Britain one of them, the second sign body 122 is the carpenter's square measured value, be blue chi measured value of civilian light chi measured value, fourth and refreshing light chi measured value one of them, and first indicates body and second indicates body according to the demonstration of distance sensing signal, makes the physical size of the first sign body and the second sign body representative corresponding.This circuit board 15 also can receive inclination angle sensing signal from inclination angle sensor 14, and this circuit board inclination angle sensing signal control display screen 12 according to this shows that one the 3rd indicates body.Please refer to Fig. 3, the 3rd indicates body 123 is shown as an inclination angle numerical value, demonstrates the level inclination of body.This circuit board also is connected in a power supply, supply circuit plate, operating portion, display screen, distance sensing device and inclination angle sensor operate the power supply of required use, this power supply can be from this external connection, or can battery be connected in circuit board use in this body equipped with battery.

Continuation is with reference to figure 2, the real work principle of this distance sensing device wherein, with laser hole drilling illuminator (or other ray emitters) object (for example wall) is launched a pulse signal, receive the signal that reflects by this object by a low noise, high sensitive laser light receiver (or other ray receivers) again, utilize following formula again, extrapolate the distance of object:

Td＝2L/C

Wherein, Td is meant transponder pulse signal and received pulse signal time delay between the two, and L is meant the distance of object to be measured, and C is meant the light velocity of propagation.

Td time delay is measured in utilization, can obtain the distance L of object to be measured relatively.

Whereby, when the user pushes operating key in the operating portion 11 that the institute desire measures, can make and be located at 13 pairs of objects of intrinsic distance sensing device (for example wall) and launch a ray, and receive the ray that reflects by this object, utilize this ray that receives to calculate the distance and position of object again, and by the control of circuit board, measured distance display in display screen, can be demonstrated the public affairs of mutual corresponding contrast, body and the carpenter's square sign body of indicating made in Great Britain simultaneously on display screen.

Aforesaid the utility model can be saved public affairs, conversion time and the manpower that measures between size and carpenter's square made in Great Britain, obtains correct numerical value and result rapidly, and its effect and advantage are remarkable.

To sum up institute is old, only is one of the utility model preferred embodiment, is not the scope that is used for limiting the utility model enforcement.Be that all equalizations of being done according to the utility model claim change and modification, be all the utility model claim and contain.
