Description

A kind of novel Horizontal angle rule

Technical field

The utility model belongs to electronic science and technology field, relates to a kind of novel Horizontal angle rule.

Background technology

Surveyor's staff conventional is at present made up of the liquid be sealed in transparent glass tube and bubble, it makes use of the principle that liquid surface is tending towards level all the time under gravity environment, when surveyor's staff and level produce angle, bubble can float higher one side, but when which demarcates level, there is no enough precision, just in the qualitative determination of certain visual angle error, therefore can be different because of the subjective judgement of operator and operator, actual calibration result is caused to occur deviation, simultaneously, surveyor's staff is being placed in the process of level, its Operational Figure Of Merit is too high, operation is difficulty comparatively.

Summary of the invention

The purpose of this utility model is to provide a kind of novel Horizontal angle rule, to solve existing level bevel protractor low precision, and operation inconvenience, the problem of environmental suitability difference.

The technical scheme that the utility model adopts is, a kind of novel Horizontal angle rule, comprise the measurement plate of base level, measure glass tube plate plate face being provided with hollow sealing, non-touching glodclad wire and resistance wire is provided with in glass tube, the inwall that glodclad wire and resistance wire are all close to glass tube extends to the other end from one end and stretches out and is connected to CPU module, CPU module is connected with LCDs, ball-type conductor is provided with in glass tube, ball-type conductor gravitate can roll in glass tube, ball-type conductor and glodclad wire remain with resistance wire and contact, the resistance wire of change in location meeting conducting different length is there is to produce different resistance values and to send to CPU module in ball-type conductor by rolling, CPU module is judged the level angle of measurement plate according to the different resistance values received and is shown by LCDs.

Further, glass tube is that opening deviates from the U-shaped of measurement plate level base.

Further, ball-type conductor is quicksilver water pearl.

Further, CPU module is provided with function button and resets for zeros data.

The beneficial effects of the utility model are, a kind of novel Horizontal angle rule, compares surveyor's staff used at present, and its degree of accuracy is high, can demarcate horizontal line comparatively accurately, more can the flat angle of measure water; Simultaneously simple to operate, automatically can be adjusted to level, good environmental adaptability.

Accompanying drawing explanation

Fig. 1 is a kind of novel Horizontal angle rule anatomical connectivity figure of the present utility model.

In figure, 1. glass tube, 2. ball-type conductor, 3. glodclad wire, 4. resistance wire, 5. function button, 6.CPU module, 7. LCDs, 8. measure plate.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

The utility model provides a kind of novel Horizontal angle rule, as shown in Figure 1, comprise the measurement plate 8 of base level, i.e. blade, measure the glass tube 1 plate 8 plate face being provided with hollow sealing, non-touching glodclad wire 3 and resistance wire 4 is provided with in glass tube 1, the inwall that glodclad wire 3 and resistance wire 4 are all close to glass tube 1 extends to the other end from one end and stretches out and is connected to CPU module 6, CPU module 6 is the integrated electronic modules with AD digital-to-analog conversion and simple data processing capacity, the minimum systematic module of such as Atmega16, glodclad wire 3 and resistance wire 4 parallel running through in glass tube 1 never contacts, CPU module 6 is connected with LCDs 7 can the horizontal angle angle value that obtains of display measurement.

Ball-type conductor 2 is provided with in glass tube 1, ball-type conductor 2 is quicksilver water pearl, the solidifying point of mercury is :-39 DEG C, boiling point is: 356.7 DEG C, the temperature of scope within-39 DEG C-357 DEG C can be operated in liquid form, the measurement needs of varying environment can be met, ball-type conductor 2 gravitate can roll in glass tube 1, ball-type conductor 2 and glodclad wire 3 remain with resistance wire 4 and contact, glodclad wire 3 in glass tube 1 and resistance wire 4 couple together as a conductor by quicksilver water pearl, make CPU module 6, resistance wire 4, quicksilver water pearl, to connect the complete loop of formation one with glodclad wire 3, the resistance wire 4 of change in location meeting conducting different length is there is to produce different resistance values and to send to CPU module 6 in ball-type conductor 2 by rolling, glass tube 1 measures the U-shaped of plate 8 bottom horizontal for opening deviates from.

The quicksilver water pearl made due to the opening design of glass tube 1 rolls under gravity, contact with resistance wire with wire and form one and can change generation variable resistor with level inclination under gravity, the resistance that resistance wire produces is sent to CPU module 6, CPU module 6 is judged the level angle of measurement plate 8 according to the different resistance values received and is shown by LCDs 7, accurately whether can be in horizontality by determined level chi, and obtain the angle of itself and level further, also automatically can control surveyor's staff to be adjusted to level or on blade, to arrange vernier adjustment knob manually it to be adjusted to level by connecting stand-by motor according to application difference.

CPU module 6 is provided with function button 5 and resets for zeros data, can need to carry out reset operation to data according to use.

A kind of novel Horizontal angle rule of the utility model, compare surveyor's staff used at present, its degree of accuracy is high, can demarcate horizontal line comparatively accurately, more can the flat angle of measure water, simultaneously simple to operate, automatically can be adjusted to level, good environmental adaptability.
