Description
Technical field
This utility model relates to a kind of enumerator, especially relates to the bidirectional counter of a kind of anti-theft being used on gas piping.
Background technology
Existing gear type enumerator, is by indicating the turntable rotation of numeral counting, is a kind of mechanical counter.This gear type enumerator is widely used in gas piping, and coal gas flows in pipeline and rotated by driven gear, thus realizes counting.
The existing gear counter being arranged in gas piping include watchcase, design skin surface digital rotating disk, be arranged on the gear at the watchcase back side, have drive to be connected between gear with numeral rotating disk.Coal gas is rotated by gear counter driven gear, again through the power transmission belt dynamic numeral turntable rotation counting of drive.After understanding this structure of enumerator, the mode adopting transformation gaspipe line is made the gear on enumerator reverse by some opportunistic people, and the digital rotating disk at this time counted also begins to reversion.Thus reach the purpose of gas gas leakage steathily.A kind of enumerator of now design, in order to avoid above-mentioned situation.
Summary of the invention
Technical problem to be solved in the utility model is to provide the bidirectional counter of a kind of anti-theft, it is possible to effectively prevent the enumerator reversion caused by transforming gaspipe line.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: the bidirectional counter of a kind of anti-theft, including including shell body, drive, gear train and numeral rotating disk group, described drive respectively with numeral rotating disk group, gear train engages, described gear train includes the first gear, second gear, 3rd gear and adjustment gear train, described adjustment gear train and the engagement of the first gear, the second described gear and the engagement of the 3rd gear, the 3rd described gear engages with drive, when the first described gear rotates forward, described adjustment gear train and the engagement of the 3rd gear realize the 3rd gear reversion, when the first described gear reverses, described adjustment gearset motions extremely engages with the second gear and realizes the second gear rotating forward, the second gear driven the 3rd gear reversion rotated forward.
Described adjustment gear train includes gear wheel and little gear, described gear wheel is arranged on shell body, it is provided with lever between described gear wheel and shell body, predetermined friction is there is between described lever and described gear wheel, described bull gear drive drives lever to rotate, the end of described lever is provided with little gear, and described little gear is between the second gear and the 3rd gear, and described gear wheel engages with little gear.Lever is set, is regulated the position of little gear by lever, it is achieved little gear engages from different gears in different situations.No matter reaching last first gear to rotate forward or reversion, the 3rd gear is all reversion.
Described drive includes the front-wheel and the trailing wheel that are fixed in rotating shaft, and described drive passes perpendicularly through described shell body, and described front-wheel engages with numeral rotating disk group, and described trailing wheel and the 3rd gear engage.Trailing wheel engages with the 3rd gear of certain reversion, it is possible to avoid the situation of gas gas leakage steathily.
Described digital rotating disk group includes multiple outer peripheral surface and is labeled with the rotating disk of numeral, multiple rotating disks are each perpendicular between the leading flank of shell body and adjacent rotating disk to connect, the one side of described rotating disk is covered with the gear teeth, being provided with card-bit part on the another side of rotating disk, the card-bit part on a rotating disk is stuck on the gear teeth in adjacent discs and card-bit part rotates a circle drives adjacent discs to rotate 36 degree.Numeral rotating disk group is used for realizing machinery rotation counting, and multiple rotating disks are vertically set on shell body leading flank, it is possible to show its numeral very intuitively.
Described shell body is rectangular configuration, and the both sides of shell body are separately provided for the through hole installed.It is easy to install in gas pipe.
Compared with prior art, the utility model has the advantage of that back side of shell is provided with the second gear and the 3rd gear outside, and using the first gear as drivewheel, then adjustment gear is set.When the first gear rotates forward clockwise, regulating gear and the engagement of the 3rd gear, now the 3rd gear reversion, drive rotates forward.It is to say, when the first gear rotates forward, drive rotates forward and drives numeral rotating disk group normally to count.At the second gear along, when counterclockwise rotating backward, regulating gear and the engagement of the second gear, now the second gear rotates forward, and the 3rd gear engaged with the second gear is reversion still, and drive rotates forward.It is to say, when the first gear reversion, drive rotates forward and drives numeral rotating disk group still normally to count.Therefore, if one want to make the gear direction of rotation on enumerator change and to reach the purpose that gas leaks gas steathily to be impracticable by the mode of transformation gaspipe line.This utility model can effectively prevent the enumerator reversion caused by transforming gaspipe line.
