Light, cost is lower.
Preferably, compass box is hollow hemisphere, and center of gravity block is fixed on the bottom of compass box, the centre of sphere and compass of compass box
The center of circle be overlapped.Be added center of gravity block purpose be lower the center of gravity, as long as be ok so playing the role of this object, such as
Stone.
Preferably, the both ends of the connecting shaft are equipped with ball, and ball slides in the circular orbit of external disk.
Preferably, the external disk is circular ring structure, and circular orbit is located on the inside of annulus.
When placement is parallel to the horizontal plane in the present apparatus by user, the center of gravity of compass and compass box entirety is perpendicular to horizontal plane
And it is located at lowest part, it is most stable of state at this time, when inclination, the center of gravity of compass and compass box is elevated, due to the work of gravity
With connecting shaft in external disk gliding in tracks, compass is synchronous with compass box to be slided or rotates to be adjusted in connecting shaft, until
Establish new balance.
The method for measuring the magnetic azimuth of a certain straight line using the utility model is as follows:
1. opening protection cap, the fixation spiral on pointer is unclamped, so that pointer is freely rotated, closes protection cap；
2. disposing compass on the end point of straight line, stands, be in a horizontal position to compass；
3. after indicators turn and it is static after, read the compass reading of pointer meaning, the as magnetic azimuth of the straight line.
Firstly, the utility model utilizes the principle of tumbler, compass box is changed to the hemisphere of similar tumbler, bottom adds
Entering center of gravity block keeps the center of gravity of compass box and compass entirety minimum, and compass and compass box with adjust automatically and can still be established when inclination
New balance.Relative to existing compass, do not have to consider leveling when using the utility model measurement trend, tendency, inclination angle, i.e.,
Making in the effect by external force or when being placed on slope, compass still Automatic Levelling and can easily measure azimuth,
Greatly improve the working efficiency of user.Secondly, the pedestal of compass box connection foreign side, the present apparatus is enable to place everywhere,
Random taking and placing.Furthermore compass box and external disk use more light and common PP, significantly reduce cost.In short, this is practical
New principle is simple, and device is small, easy to carry, at low cost, easy to operate, and also not high to the requirement of technical staff's use experience,
Opposite with prior art, the improvement of the utility model is positive and apparent.
