Abstract

The utility model discloses a level instrument. In the utility model, a dial with angle graduation is fixed on a shell body; connecting lines from 0 DEG to 180 DEG are vertical with the lower surface of the shell body; the center of the dial is provided with a pointer in 180 DEG and a gravity hammer by a shaft sleeve and a pointer shaft; the shaft sleeve and the pointer shaft can be smartly rotated; the shell body is provided with a window on the position corresponding to the dial. Because of the function of the gravity hammer, the angle relation of the line surface of a tested space and the horizontal line can be conveniently and exactly read out from the relationship of the pointer and the dial when the level instrument testing space line surface.

Description

A kind of level meter

The utility model relates to the level meter of a kind of measurement space line face and horizontal line angular relationship.

Existing common level meter all is to adopt vacuole to show, utilizes the position of bubble in fluid column to judge whether level of space line face, though this method can be measured whether level of space line face roughly, can not measure its angle of inclination.

The purpose of this utility model is to provide a kind of accurately measurement space line face of cheapness and the level meter of horizontal line angular relationship.

The utility model by base be the smooth housing of facing directly, indicate 0 the degree to positive and negative 180 the degree index dial, pointer, needle pivot, gravity drop hammers form.Index dial is fixed in the shell, 0 degree is faced directly with the vertical base of line between 180 degree on the index dial, the position windowing that outer casing frontispiece is corresponding with index dial exposes scale, on window, cover transparent dust cap, in the index dial center fixation pointer axle sleeve is installed, plug-in mounting needle pivot in the axle sleeve can rotate between needle pivot and the axle sleeve flexibly, an end that is positioned at the index dial front at needle pivot fixedly mounts pointer, and the other end and pointer are 180 degree gravity drop hammers are installed.When level meter is placed on horizontal space line face, because the gravity drop hammer effect makes pointer perpendicular to the chassis, at this moment pointed 0 is spent, and when detected space line face tilt, gravity drop hammer makes the needle deflection certain angle, and at this moment the angle of pointed is the angle of detected space line face tilt.

The utility model also can have another technical scheme under same inventive concept, the position that is corresponding index dial top scale on the smooth housing of facing directly, the housing by base has window, be installed on and indicate 0 degree to rotatable index dial, the window fixed of positive and negative 180 degree in the shell and pointer (line at pointer and index dial center is perpendicular to the smooth base of facing directly of shell) is arranged, be fixed on that index dial 180 is spent the gravity drop hammer at the back sides, the transparent dust cap that is fixed on window is formed.During use the level meter seating plane is placed on the detected space line face, because the effect of gravity drop hammer makes the degree of 0 on the index dial all the time up, thereby can fasten from the pass of pointer and index dial easily and read detected space line face and horizontal angular relationship.

Owing to adopt said structure, make the utility model can not only measure whether level of detected space line face easily, and can accurately read the angle of inclination of detected space line face when out-of-level.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of level meter.

Fig. 2 is that Figure 1A-A is to cut-open view.

Fig. 3 is the front view of another embodiment of level meter.

Fig. 4 is Fig. 3 A '-A ' cut-open view.

As shown in Figure 1, 2, indicating 0 degree to positive and negative 180 index dials 2 of spending is fixed in the shell 1, line vertical smooth base on the index dial 2 between 0 degree and 180 degree faces 8 directly, the positive position windowing corresponding with index dial 2 of shell 1 exposes scale, on window, cover transparent dust cap 7, in index dial 2 center fixation pointer axle sleeve 4 is installed, plug-in mounting needle pivot 5 in the axle sleeve 4, can rotate flexibly between needle pivot 5 and the axle sleeve 4, an end that is positioned at index dial 2 fronts at needle pivot 5 fixedly mounts pointer 3, and the other end and pointer 3 are 180 degree gravity drop hammers 6 are installed.When level meter is placed on horizontal space line face, because gravity drop hammer 6 effects make pointer 3 perpendicular to chassis 8, at this moment pointer 3 points to 0 degree, and when detected space line face tilt, gravity drop hammer 8 makes pointer 3 depart from certain angle, and the angle of pointer 3 sensings at this moment is the angle of detected space line face tilt.

Shown in Fig. 3,4 another embodiment of level meter, be fixed with axle 5 in the housing 1, axle is with the axle sleeves 4 that can rotate flexibly with axle 5 on 5, be fixed with index dial 2 on the axle sleeve 4, be carved with 0 degree on the index dial 2 to positive and negative 180 degree, the fixing gravity drop hammer 6 at the back side at the positive and negative 180 degree places of index dial 2, corresponding index dial 2 upper limb scale places have window above housing 1 front, the pointer 3 that is fixed on the housing 1 is arranged in the middle of the window, pointer 3 faces 8 with the line at axle 5 centers directly perpendicular to the smooth base of housing 1, and window is stamped transparent dust cap 7.Place on the detected space line face facing 8 under the level meter directly during use,, therefore can fasten with the pass of index dial 2 from pointer 3 easily and read detected space line face and horizontal angular relationship because the effect of gravity drop hammer 6 makes the degree of 0 on the index dial 2 all the time up.
