Abstract
The utility model discloses a horizontal angulation measuring instrument, which comprises a watch case (1), a revolution axis (5) provided in the watch case (1), and a weight (4) and a guide finger (6) which are provided on the revolution axis (5) coaxially. The utility model is characterized in that one side of the revolution axis (5) is provided with a driven axle (10), one end of the driven axle (10), which projects beyond the watch case (1), is provided with a short guide finger (9), and the revolution axis (5) and the driven axle (10) are connected together by a pair of speed increasing gears (8, 9).
Description
Technical field:
The utility model relates to surveying instrument, a kind of angel measuring instrument, and specifically a kind of level meter is applicable to building, decoratees engineering construction.
Background technology:
Traditional level meter is installed a glass bubble and is constituted in basic chi.Therefore can only see whether level of tested surface, can't learn that how many its angles of inclination is, is not easy to levelling.Patent Office of the People's Republic of China's Granted publication on February 12nd, 1997 a kind of " level angle meter " (notification number is: utility model patent CN 2247328Y), this utility model is that a rotating shaft is set in watchcase, coaxially in the rotating shaft be provided with that a weight and a pointer constitute, utilize the downward principle of gravity to measure level angle.Therefore this utility model can't show low-angle, thereby measuring accuracy is restricted owing to be subjected to the restriction of dial plate area.
Summary of the invention:
Technical problem to be solved in the utility model is to improve display precision.
The technical scheme that the utility model solves the problems of the technologies described above is:
A kind of level angle measuring instrument, bag by watchcase, be located at the rotating shaft in the watchcase, the weight and the pointer of coaxial setting in rotating shaft, a side that it is characterized in that described rotating shaft is provided with a driven shaft, stretch out an end of watchcase on the driven shaft and establish a short pointer, rotating shaft and driven shaft are connected by a pair of increase gear.
Because the utility model has been set up a driven shaft in watchcase, therefore the display precision than prior art has improved a grade.
Embodiment:
Description of drawings:
Fig. 1 and Fig. 2 are the structural representation of an impracticable novel non-limiting example, and wherein Fig. 1 is a front view, and Fig. 2 is a left view.
Embodiment:
Referring to Fig. 1 and Fig. 2, first important additional technical feature of the present utility model is that the below of described watchcase 1 is provided with ruler 2.So both increase measuring basis, reduced the local uneven measuring error of bringing of tested surface, also increased the function of a common ruler.
In order not allow table shelter from the display scale of ruler, second important additional technical feature of the present utility model is that described ruler 2 is provided with support 3, and watchcase 1 is fixed on (referring to Fig. 1 and Fig. 2) on the support 3.
Level angle measuring instrument described in the utility model is to utilize the downward principle design of gravity to form, during use ruler is put on the tested surface, in case tested surface tilts, under the effect of weight 4, rotating shaft 5 is just rotated, drive indicator 6 and rotate synchronously, the scale on the indicator indication dial plate is the pitch angle of tested surface.Be located at simultaneously that active gear wheel 7 in the rotating shaft 5 just drives driven pinion wheel 8 driven shafts 10 and short pointer 9 rotates synchronously.If initiatively the ratio of gear of gear wheel 8 and driven pinion wheel 9 is 10, short pointer 9 rotations 1 circle is promptly represented 1 degree so, that is the hour hand 9 shown orders of magnitude depend on the ratio of gear of active gear wheel 8 and driven pinion wheel 9.For the back lash that reduces measuring error active gear wheel 8 and driven pinion wheel 9 should be as far as possible little.
Method for making beyond the utility model is above-mentioned is implemented to get final product with reference to accompanying drawing.
Claims (3)
1, a kind of level angle measuring instrument, bag by watchcase, be located at the rotating shaft in the watchcase, the weight and the pointer of coaxial setting in rotating shaft, a side that it is characterized in that described rotating shaft is provided with a driven shaft, stretch out an end of watchcase on the driven shaft and establish a short pointer, rotating shaft and driven shaft are connected by a pair of increase gear.
2, a kind of level angle measuring instrument according to claim 1 is characterized in that the below of described watchcase is provided with ruler.
3, a kind of level angle measuring instrument according to claim 2 is characterized in that described ruler is provided with support, and watchcase is fixed on the support.
