Abstract

The utility model relates to a meshing cursor detecting ruler with length measuring function, which comprises a main ruler, a vernier cursor, and a measuring data numerical display device. The end part of the left upper side close to the main ruler is provided with a measuring jaw which is wide in 3mm, the measuring jaw can be used under some narrow conditions and can be used for detecting the meshing depth between comb teeth of an escalator and a moving pavement and step footplate grooves, the gap between the step footplate surface and the tooth root of the comb teeth, and the like. The cursor detecting ruler enlarges the use range and the use, meets the accuracy requirement, increases the new measuring range for the common use measuring tool, and provides the convenience for the use.

Description

Engagement vernier detection ruler
Technical field
The utility model relates to a kind of vernier detection ruler with length measurement function, belongs to the survey instrument technical field.Be specially adapted at escalator and moving sidewalk manufacturing, installation, maintenance, use and detect the depth of engagement of finishing its broach and step pedal groove in the check and the measurement in the gap between step pedal face and the broach tooth root, can solve the limitation that existing vernier caliper can not be finished the measurement under the narrower occasion.
Background technology
Make the requirement of installation specification (GB16899-1997) and the requirement of escalator and moving sidewalk supervision and inspection rules according to escalator and moving sidewalk, in manufacturing, the installation, maintenance of escalator and moving sidewalk, use and detect in the check, need control gap size such as between the depth of engagement, step pedal face and the broach tooth root of its broach and step pedal groove, to guarantee passenger's safe handling.Because these gaps are important critical sizes, so be the project that to measure and to control.But because present existing vernier caliper can only be used for the measurement of looser occasion, and when above measuring object implemented in-site measurement, because residing position, its position is narrow, its measuring claw is put to enter position to be measured at all, cause the gap size at these positions directly not measure with existing vernier caliper, this gives manufacturing, the on-the-spot installation of escalator and moving sidewalk and detects check and brought difficulty.
Summary of the invention
The purpose of this utility model then is at above-mentioned existing problems, a kind of novel engagement vernier detection ruler is provided, this detection ruler has the advantage and the function of existing vernier caliper, can measure the depth of engagement of broach and step pedal groove again easily and directly, gap equidimension between step pedal face and the broach tooth root, the result who measures can show from direct form with numeral on the digital type display device of this chi, the data that direct reading is measured, the shortcoming of having avoided the scale indication to misread has easily made things convenient for on-the-spot use.
Realize that the technical matters that the utility model solves is: the engagement vernier detection ruler of present embodiment is a kind ofly can directly demonstrate the vernier detection ruler of measuring numerical value with digital form from the digital type display device of this chi, and this chi includes main scale [12] and fixedly measuring jaw dewclaw [1], lower claw [11], vernier scale [9] and movable measuring jaw dewclaw [2] thereof, lower claw [10] and digital type display device [a 5] composition on the engagement vernier detection ruler.Fixedly measuring jaw dewclaw [1] physical dimension of main scale [12] is wide 3mm * thick 3mm, movable measuring jaw dewclaw [2] physical dimension of vernier scale [9] is wide 3mm * thick 2mm, and the outward flange of dewclaw [1] the left side cutting edge of main scale [12] measuring claw and the left end of main scale [12] protrudes 0.8mm slightly.
The utility model is by the improvement to existing vernier caliper, make it have the function of measuring some narrow occasion, make this vernier detection ruler not only satisfy its measurement function but also satisfied the requirement of its precision, increased a kind of new measurement range for this measurer commonly used, the data that record when using this engagement vernier detection ruler are accurate, directly perceived, and brought convenience to use.

Embodiment
The utility model engagement vernier detection ruler has main scale [12] and fixedly measuring jaw dewclaw [1], lower claw [11], vernier scale [9] and movable measuring jaw dewclaw [2] thereof, lower claw [10] and digital type display device [a 5] composition on the engagement vernier detection ruler, as Fig. 1.Movable measuring jaw dewclaw [2] physical dimension of the fixedly measuring jaw dewclaw [1] of main scale [12] and vernier scale [9] is the measuring claw of long 2mm * thick 3mm, the outward flange of the left end of the dewclaw of its measuring claw [1] left side cutting edge and main scale [12] has the cutting edge that protrudes 0.8mm slightly, as Fig. 2,3.
During use, at first adjust the zero-bit of engagement vernier detection ruler, method is a vernier detection ruler closure, and the fixedly measuring jaw dewclaw [1] of main scale on the vernier detection ruler [12] overlaps with the movable measuring jaw dewclaw [2] of vernier scale [9], as Fig. 4.Open the power switch button [8] of digital type display device [5] then, press the button [7] of digital type display device [5], digital type display device [5] display digit 0.00 has promptly been finished the adjustment of the zero-bit of engagement vernier detection ruler.When implementing to measure then, hand engagement vernier detection ruler, put into the engagement position of the broach and the step pedal groove of escalator or moving sidewalk, as Fig. 5.Move the vernier scale [9] on the engagement vernier detection ruler, the dewclaw [1] of its movable measuring jaw, the measurement cutting edge of [2] are contacted with measured, holding screw [4] on the vernier scale is tightened, take out detection ruler and observe the numerical value display result of the measurement on the digital type display device [5], the physical size of its measuring point is: display result numerical value+3mm is the length dimension data at measured position.This engagement vernier detection ruler can also be measured the gap length sizes such as distance between horizontal clearance, handrail opening part and the guide rail or the armrest support of step, pedal or the adhesive tape of escalator or moving sidewalk and apron plate in addition, can be used widely aspect escalator and the moving sidewalk.
