Abstract

The utility model relates to a slope level scale. A reference surface is arranged on a main casing, a scale dial is parallel to the vertical surface of the reference surface, the two equidistant half circumferences of the scale dial are evenly distributed with scales of 0 to 180 DEG, and the distance between the scale of 0 DEG and the reference surface is shortest; a pointer shaft is vertically arranged in the center of the scale dial, and a pointer provided with a plumb is sheathed on the pointer shaft in a vertical movable fit. People can conveniently read the value of the slope of the measured plane or judge whether the measured plane is level or not through observing the position of the pointer, so the utility model has simple operation, and is not easy to affect by environmental and artificial factors.

Description

Gradient surveyor's staff

The utility model relates to measuring appliance, in particular a kind of dip stick of measuring the gradient or level.

In construction, carry out the employed surveyor's staff of plane surveying so far, be called spirit-leveling instrument again, no matter import or homemade all be bubble type, be as reference field with the one plane, be provided with an airtight light-transmissive fluid container with the reference field opposite face, sign is carved with in vessel surface central authorities, contains a bubble in the solution of container, rely on visual bubble whether placed in the middle in the sign of vessel surface, judge whether tested surface is surface level.Because this type of surveyor's staff can only be judged whether level of tested plane, can not judge the angle of tested plane and surface level, approaching because of adjusting bubble centering operation aberration loaded down with trivial details and bubble and solution boundary again, thereby the usable range of this type of surveyor's staff is restricted, and influence because of light, visual angle or environment, whether visual bubble is placed in the middle, and its measurement result easily produces than large deviation.

The purpose of this utility model provides a kind of gradient surveyor's staff, is used for the angle of tested plane of direct-reading and surface level, and usable range is wide, and is simple to operate and be not subjected to environment and artificial factor.

The purpose of this utility model is achieved in that a kind of gradient surveyor's staff, on main casing, be provided with reference field, the parallel graduation apparatus dish that is provided with the vertical plane of reference field, scale dial plate equal intervals two halves circumference uniform distribution be carved with 0-180 ° scale and indicate 0 ° scale and the distance of reference field the shortest, in the face of the scale dial plate locates to be provided with the neutral that stops pointer for 135 ° at left-hand, central vertical at the scale dial plate is provided with needle pivot, vertical sheathed movingly one pointer that sets plummet on needle pivot, described scale dial plate and pointer are covered in the transparent glass cover by button, with reference field two ends and relative parallel surface on two ends be arranged with and put magnet.

Because gradient surveyor's staff of the present utility model has said structure, can make things convenient for the value of slope of directly reading tested plane or whether judge level by the indicated scale of visual pointer, and simple to operately be not subject to the influence of environment and human factor, the value of slope that can be widely used in field construction and indoor construction scene is measured.

With reference to the accompanying drawings embodiment of the present utility model is described in detail, wherein:

Fig. 1: be the front outside drawing of the utility model gradient surveyor's staff;

Fig. 2: be the midsection figure of the utility model gradient surveyor's staff;

Fig. 3: the expression measured value is the synoptic diagram of 31 ° of the gradients;

Fig. 4: the expression measured value is the synoptic diagram of 180 ° of levels;

Fig. 5: the expression measured value is vertical 90 ° synoptic diagram;

Fig. 6: the expression measured value is the synoptic diagram of 142 ° of the gradients;

See also Fig. 1,2, a kind of gradient surveyor's staff, on main casing 1, be provided with reference field 10, the parallel graduation apparatus dish 2 that is provided with the vertical plane of reference field 10, scale dial plate 2 equal intervals two halves circumference uniform distributions are carved with 0-180 ° scale 4 and indicate that 0 ° scale 4 is the shortest with the distance of reference field 10, in the face of scale dial plate 2 locates to be provided with the neutral 9 that stops pointer 3 for 135 ° at left-hand, central vertical at scale dial plate 2 is provided with needle pivot 8, vertical sheathed movingly one pointer 3 that sets plummet 6 on needle pivot 8, described scale dial plate 2 and pointer 3 covered in the transparent glass cover 7 by button, with reference field 10 two ends and relative parallel surface on two ends be arranged with and put magnet 5.

Gradient surveyor's staff is the principle making that equates that according to two jiaos corresponding both sides are vertical, because pointer 3 sets plummet 6, under graviational interaction, pointer 3 directions are vertical with surface level, the center of the needle pivot 8 of scale dial plate 2 is vertical with reference field 10 with the extended line of scale 4 on lines of 0 ° of sign, so scale dial plate 2 is from indicating that 0 ° begins to be reference field 10 and the folded angle of surface level to pointer 3 indicated scales 4.

In use, when reference field 10 reclines tested surface, pointer 3 indicated scales 4 are the value of slope of tested surface, as shown in Figure 3, pointer 3 indicating graduations are 31 °, and the value of slope that promptly is tested surface is 31 °, because the suction-operated of magnet 5, even the stop angles that the gradient reclines greater than gradient surveyor's staff also can guarantee closely to recline with tested surface, stop gradient surveyor's staff to slide or disengaging, as shown in Figure 4, the angle on tested plane is 180 °, and as shown in Figure 5, the angle on tested plane is 90 °, as shown in Figure 6, the angle on tested plane is 142 °, when pointer 3 indicating graduations 4 signs are 0 °, promptly represents level.

Described gradient surveyor's staff is having multiple variation in the scope of above-mentioned making principle, change as profile, the conversion of the arrangement of magnet, the scale of scale dial plate or pointer adopt reflecting coating etc., the version of many gradient surveyor's staffs all can not break away from technical scheme described in the utility model.
