Abstract
A digitally display dial indicator is disclosed by the utility model, which primarily consists of a housing, a surveying rod, a display screen and a sensory control chip inside the housing. The surveying rod is connected with the housing through a sliding and spacing structure; the display screen is connected with one side of surface of the housing through a linkage structure. The utility model is characterized in that the linkage structure consists of a support, a link block and a trip shaft on one side of the display screen; a slot matched with the link block is provided on the support and the link block is inside the slot, and is connected with the support rotatablely through a horizontal axis of rotation that extends outwards. A C-shaped axocoel is provided at the position opposite to the side of the display screen on the link block and the trip shaft is clamped inside the C-shaped axocoel and is connected with the link block rotatablely. In this way, a perpendicular axis of rotation of the display screen is formed. The display screen can turn at multiple angles by adopting the utility model, and meets requirements of observers to read numbers at arbitrary angles and prevents read fault.
Description
Technical field
The utility model relates to a kind of survey instrument, is specifically related to a kind of dial gauge that has the reading display screen.
Background technology
Dial gauge is the higher comparison measurer of a kind of precision, and it can only measure relative numerical value, can not measure absolute figure.Be mainly used to check the shape and the site error (as circularity, flatness, verticality etc.) of workpiece, also be usually used in the accurate centering of workpiece, proofread and correct clamping position etc.
Dial gauge is divided into mechanical and two classes digital display type, and the mechanical type measuring principle is: change the straight-line displacement of sounding rod the angular displacement of pointer on dial plate into by machine driven system, along the uniform scale on the dial plate circumference, thereby obtain measuring numerical value.Owing to be to rely on mechanical gear train to record data, thereby the susceptibility that detects is limited, is prone to test error; The dial gauge of digital display type then records data by sensor (for example grating sensor), and control chip control display shows numerical value, thereby responsive change is high, can reduce measuring error relatively; Simultaneously, owing to can directly detect the displacement of measuring staff, gear train assembly can be set, thereby structure is simpler.
Digital display centimeter is by main body, case and be arranged at the display part in the main body and on the case and measure the transducing signal processing section and form, and its display part comprises case, be distributed in the lip-deep various function buttons of case, be arranged at the display in the case and be positioned at the display chip of display rear end; Measure the transducing signal processing section and then comprise measuring staff, sensor and the functional chip that is connected with main body by slip and position limiting structure.In the prior art, because display chip and functional chip are solidified into one, therefore, can not rotate mutually between display part and the measurement transducing signal processing section, this digital display centimeter is when carrying out the measurement of different azimuth, the direction that shows reading is fixed, thereby, when measurement environment comparatively abominable, as insufficient light, under the situations such as viewing angle is limited, numeral on the LCDs just is difficult to identification, thereby brings difficulty to reading of data, causes user's inconvenience, even produce phenomenon such as read error, influence measuring accuracy.
Summary of the invention
The utility model purpose provides a kind of digital display centimeter that is easy to observe and read measurement data, thereby can avoid reading error.
For achieving the above object, the technical solution adopted in the utility model is: a kind of digital display centimeter, mainly by housing, measuring staff, display screen and the sensing control chip of being located in the housing are formed, described measuring staff is connected with housing with position limiting structure through slip, display screen is connected with surface of shell one side through a syndeton, described syndeton is by support, contiguous block is formed with the trip shaft that is arranged at display screen one end, described support is provided with the draw-in groove that cooperates with contiguous block, contiguous block is arranged in the draw-in groove, and through outward extending horizontal rotating shaft and support are rotationally connected respectively, described contiguous block is provided with C profile shaft chamber corresponding to display screen side, described trip shaft is arranged in this C profile shaft chamber, be rotationally connected with contiguous block, constitute the vertical rotation axis of display screen.
In the above-mentioned technology, " sliding and position limiting structure " between described measuring staff and housing is prior art, and be identical with existing digital display centimeter; Described sensing control partly comprises sensor, functional chip and display chip, in use, and by the motion conditions of sensor sensing measuring staff, and convert thereof into electric signal and input in the functional chip, calculate measured value, show, for reading by the display chip control display screen.Sensor is a prior art, can adopt the grating sensing structure, holds the grid sensing arrangement, perhaps other sensing arrangement of the prior art.
In the technique scheme, be provided with wire guide along direction of axis line in the described trip shaft, the medial extremity of the nearly housing of contiguous block is provided with opening, and the axocoel of described wire guide in contiguous block constitutes cable tray to open communication.
In the technique scheme, the opening part in described C profile shaft chamber is provided with the limit chamber wall of relative bending, is provided with the annular groove that cooperates with it corresponding to the trip shaft at limit chamber wall place, constitutes buckle and connects.
Principle of work of the present utility model: during use, display screen can rotate by the vertical rotation axis on contiguous block, realizes the rotational freedom of 180 degree of vertical direction; Also can rotate simultaneously around trip shaft, and when display screen goes to the surface of shell vertical direction, be that horizontal rotating shaft rotates 90 degree, display screen just can be finished the arbitrarily angled upset of 270 degree of vertical direction along trip shaft, thereby realize the multi-angle observation of display screen numeral is read, be applicable to that viewing ray is abominable or the working environment that observation angle is limited.
Because technique scheme utilization, the advantage that the utility model compared with prior art has is: cooperate because the utility model adopts the horizontal rotating shaft of contiguous block to intersect with the vertical rotation axis of trip shaft, finish the multi-angle upset of digital display screen, when measurement, reading, according to the observation angle or the requirement of demonstration light, adjust the observation angle of display screen arbitrarily, so that the measurement data that shows on the clear identification liquid crystal display of energy is avoided error in reading.
