Abstract
The utility model relates to a gradient measuring tool, in particular to a pointer type level bar for horizontal measuring. The pointer type level bar contains a bar body, in which a window and a transparent faceplate with a dial are provided; a main shaft is arranged with a heavy hammer, wherein the two end of the main shaft are fixed on a bearing frame at both sides via bearings, the heavy hammer is fixed on the main shaft, a pointer is fixed on the main shaft. The utility model has simple structure, convenient producing, good indicating effect, high measurement precision and wide usage scope.
Description
Technical field
The utility model relates to a kind of instrument of measuring degree of tilt, particularly relates to a kind of pointer surveyor's staff that is used to measure level.
Background technology
At present, the various pointer surveyor's staff on the market comprises the chi body, and window and transparent panel are arranged in the chi body, the horn craving scale is arranged in the panel, and the chi body has main shaft, hangs with weight on the main shaft, fixedly on the weight, the structure of these pointer surveyor's staffs is all comparatively complicated, and is cumbersome during making for pointer.Chinese patent ZL02209983.4 discloses the applicant's a kind of " pointer surveyor's staff ", and its pointer also is to be fixed on the weight, and the number of pointer is just limited on weight because pointer is solid, and also restriction to some extent of the position of installing.
Summary of the invention
The purpose of this utility model is in order to solve above-mentioned existing deficiency, and provides a kind of simple in structure, easy to install, the novel pointer surveyor's staff that measuring accuracy is high.
Pointer surveyor's staff provided by the utility model is achieved through the following technical solutions above-mentioned purpose: this pointer surveyor's staff includes the chi body, in the chi body window is arranged, and on transparent panel, the transparent panel index dial is arranged; Weight is arranged on the main shaft, and wherein on the bearing support of both sides, wherein weight is fixed on the main shaft by bearing fixing at the main shaft two ends, and pointer is fixed on the main shaft.On the bearing support of both sides, under the effect of weight, main shaft is free to rotation by bearing fixing at the two ends of main shaft, and pointer is also along with rotation together, thus the purpose of realization indication level.
Pointer surveyor's staff provided by the utility model can also be further perfect, also has window, transparent panel, index dial and a pointer in the symmetric position of window, transparent panel, index dial and pointer; Pointer can be installed on the weight line direction or be installed on the weight line opposite direction.Like this, when weight rotated, pointer can indicate the situation of level easily, again very intuitively; Two index dials are arranged, can read from the both sides of surveyor's staff, very convenient.
Pointer surveyor's staff provided by the utility model can also be made halfround bar slice with weight, can rotate easily like this; Weight can be fixed on the main shaft with the spiral shell pin, can not produce the relative slip between weight and the main shaft, to guarantee the indicating correct of pointer.
Pointer surveyor's staff provided by the utility model can also be placed with the circuit of being made up of battery and light emitting diode on chi body 1, can use in the not so good place of light like this, also can use at night.
The utility model is simple in structure, and is easy to make, and indicating effect is good, and the measuring accuracy height is applied widely.

Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Embodiment 1: the pointer surveyor's staff that present embodiment provided, see Fig. 1, and include chi body 1, a window 2 and transparent panel 3 are wherein arranged in chi body 1, horn craving scale 4 is arranged in the panel; Main shaft 5 on the chi body 1 is fixed on the bearing support 11 by two bearings 12.Be fixed on the main shaft 5 with the weight 8 of screw 9 with halfround bar slice, triangular prism 6 is made in the place that main shaft 5 contacts with bearing 12, one of them rib with contact the accuracy when guarantee measuring with bearing 12; Screw thread is made in two outer ends of main shaft 5, and pointer 10 covers are fixed with nut 7 in the above.Be fixed with and the reciprocal pointer 10 of weight line at the two ends of weight 8.When using this pointer surveyor's staff measurement level, straight down, pointer 10 just points to the direction opposite with the weight line to weight 8 under the effect of gravity, thus definite plane of being surveyed level whether.
Embodiment 2: the pointer surveyor's staff that present embodiment provided, see Fig. 2, and include chi body 1, a window 2 and transparent panel 3 are wherein arranged in chi body 1, horn craving scale 4 is arranged in the panel; Corresponding position on chi body 1 also has window 2 ', transparent panel 3 ', horn craving scale 4 ' accordingly; Main shaft 5 on the chi body 1 is fixed on the bearing support 11 by two bearings 12; Triangular prism 6 is made in the place that main shaft 5 contacts with bearing 12, and one of them rib contacts with bearing 12, the accuracy when measuring with assurance; Screw thread is made in two outer ends of main shaft 5, pointer 10 covers in the above, carrying out fixing screw 9 with nut 7 is fixed on the weight 8 of halfround bar slice on the main shaft 5, be fixed with at the two ends of weight 8 with the reciprocal pointer 10 of weight line and with the equidirectional pointer 10 ' of weight line, present embodiment also is placed with the illuminating circuit of being made up of battery 13 and light emitting diode 14 in window 2 (window 2 '), can or carry out work night in the not so good place of light.
