Embodiment 1

[0028] Such as figure 1 As shown, the angle measuring instrument of this embodiment includes a rotating part 202 and a base 201, and the rotating part 202 and the base 201 are connected in rotation. The rotating part 202 is provided with a first light emitter 204, which is fixed relative to the rotating part 202 and rotates with the rotating part 202; the base 201 is provided with a second light emitter 203, which is fixed relative to the base 201; when the first After the light emitter 204 rotates an angle with the rotating part 202 , the laser light respectively emitted by the first light emitter 204 and the second light emitter 203 forms a measurement angle corresponding to the angle of rotation of the rotating part 202 .

[0029] Such as figure 2 As shown, the circuit diagram of the first embodiment of the present invention, in order to measure the angle more accurately, the angle measuring instrument of this embodiment also includes a sensing module 101, a control modul...

Embodiment 2

[0033] In order to better implement the angle measuring instrument to measure the angle of an object on the horizontal plane, the present invention provides a second embodiment on the basis of the first embodiment.

[0034] Such as image 3 and Figure 4 As shown, the angle measuring instrument also includes a level display device and a level adjustment device. The horizontal display device is arranged on the top of the rotating part 202 and includes a first horizontal blister box 206 and a second horizontal blister box 207. The first horizontal blister box 206 and the second horizontal blister box 207 can be perpendicular to each other or form an angle. The first horizontal blister box 206 and the second horizontal blister box 207 here can also be replaced by horizontal mercury blister boxes.

[0035] This embodiment adopts three groups of level adjustment devices, the first group of level adjustment devices includes the first knob 208 and the first support foot 210, the se...

Embodiment 3

[0037]In order to facilitate the user to observe the measured value of the angle measuring instrument, the present invention provides a third embodiment by improving the circuit of the first embodiment.

[0038] Such as Figure 5 As shown, the angle measuring instrument also includes a direction sensing module 104, and the direction sensing module 104 is electrically connected to the control module 102; the rotating part 202 rotates, and the direction sensing module 104 generates a direction signal according to the direction in which the rotating part rotates, and transmits the direction signal to The control module 102, the control module 102 adjusts the direction in which the display module 103 displays the angle measurement value according to the change of the direction signal, so that it is convenient for the user to observe. Other components or modules of this embodiment are similar to those of the foregoing embodiments, so details are not described here.

The invention can effectively improve precision of the angel measuring instrument.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an angle measuring instrument and a measuring method. Background technique [0002] In daily life and industrial construction, people often need to use an angle measuring instrument to measure the angle of a certain angle. An existing angle measuring instrument includes a rotating part and a base, the base and the rotating part respectively fix a dial and a pointer, and the rotating part and the base respectively fix a laser emitter, and the laser emitter can emit laser light. When using the angle measuring instrument to measure the angle to be measured, turn the rotating part of the angle measuring instrument, the laser emitter fixed on the rotating part will rotate accordingly and emit laser light, and the laser emitter on the base also emits laser light, between the two laser beams Form an included angle corresponding to the included angle to be measured. With the rotation of the ...
