A kind of lighter flow detection and adjusting device
Technical field
The present invention relates to lighter and detect adjusting device, especially a kind of lighter flow detection and adjusting device.
Background technology
Lighter is as a kind of dangerous material, and its flame height is necessary Interventions Requested in the production process.According in China's inspection and quarantining for import/export industry standard to the regulation of outlet lighter dangerous material inspection procedure, the qualified criterion of flame height of lighter is: the lighter that has the flame height adjuster, 98% test specimen should satisfy, when the flame height adjuster is positioned at maximum flame location, igniting back in 5 seconds flame height be 150 millimeters or below, when the flame height adjuster is positioned at minimum flame location, igniting back in 5 seconds flame height be 50 millimeters or below; The lighter that does not have the flame height adjuster, 98% test specimen should satisfy, have after the igniting of windscreen in 5 seconds flame height be 50 millimeters or below, in back 5 seconds of the igniting of no windscreen flame height be 100 millimeters or below.
Therefore, when the assembling lighter, generally before the lighter flame adjusting ring is packed adjusting nut into, need first flame detection height, and against regulation flame height is regulated by rotating adjusting nut.At present, the checkout gear of flame height has following several: (1) is easy, and measurement mechanism---scale carries out the artificial visually examine and compares detection as benchmark.At the bottom of this checkout gear automaticity, efficient is slow, and testing staff's labour intensity is big, works long hours and may damage eyes; And human factor is many, and there is certain error in observation data, and certainty of measurement is low.(2) be to adopt the measurement means of imaging method as flame height.There is the cost height in this image acquistion system, to the demanding defective of environment for use.(3) be to change the Temperature Distribution of flame into voltage signal, by analog-digital converter voltage signal changed again, go out flame height by microprocessor according to the calculated with mathematical model of flame at last, be presented on the display screen after comparing by thermocouple.This device need be responded to flame by thermocouple, therefore needs the complicated circuit structure of design, and need often safeguard thermocouple so that prevent the sensitivity of electric heating coupling and reduce.In addition, more than several measurement mechanisms all need lighter is lighted, again flame is measured, can only test lighters light the lighter that the flame place of relating to, back does not have plastic components, otherwise flame can melt plastic components, is subjected to the structure influence of lighter own big, only is applicable to the part of detecting type; Testing environment is required high (as windproof); After flame height measured, filter out against regulation lighter, still by manually regulating, carry out adjusted in concert after detection then, still need after the adjusting to carry out duplicate detection, efficient is low.
Summary of the invention
The objective of the invention is provides a kind of lighter flow detection and adjusting device in order to solve above-mentioned the deficiencies in the prior art, by measuring the flame height that the lighter air-flow obtains lighter indirectly, and rotate adjusting nut to correct position according to the size that goes out throughput, make to measure with regulating and carry out synchronously.
In order to achieve the above object, a kind of lighter flow detection and adjusting device that the present invention is designed, it is characterized in that two clamping plate that it comprises ventilating shaft, is enclosed within anchor clamps holder and the anchor clamps regulating part on the ventilating shaft and is symmetricly set on anchor clamps holder both sides, described two clamping plate are configured for the ears anchor clamps of clamping lighter pin, and described anchor clamps holder is fixedly mounted on the ventilating shaft; The middle part of described clamping plate is connected on the bottom of anchor clamps holder by alignment pin, the top of clamping plate has an adjustment hole that makes progress and slope inwardly and be provided with, one removable pin runs through described adjustment hole the top of clamping plate is connected on the anchor clamps regulating part, and the inboard of clamping plate bottom forms a clamp port; The center of described ventilating shaft has an air guide channel that is positioned at clamp port top, the upper end of described air guide channel connects a flow detector, the lower end of described air guide channel is used for docking with the outlet of lighter pin, the both sides, bottom of ventilating shaft respectively have a bar-shaped trough, the inwall of described ventilating shaft bottom is provided with many vertical draw-in grooves, described vertical draw-in groove is used for the lighter flame adjusting nut is circumferentially located, the bottom of clamping plate places bar-shaped trough and clamp port to be located at the top of draw-in groove, the bottom of clamping plate stops adjusting nut to move upward, and moves upward thereby avoid air-out needle to drive adjusting nut.
When being subjected to the external force effect, the anchor clamps regulating part moves upward with respect to anchor clamps holder and ventilating shaft, because the guide effect of adjustment hole, rotate around alignment pin at two clamping plate middle part, two clamp ports collapse to and clamp air-out needle, then anchor clamps regulating part drive air-out needle moves upward and makes its venting, gas enters in the air guide channel, flow detector detects throughput, go out throughput and can be converted into corresponding flame height, owing to adjusting nut is positioned in the vertical draw-in groove, can rotates the position that ventilating shaft is adjusted adjusting nut by external force, thereby change the throughput that of air-out needle, after making igniting, the flame height of lighter is in the critical field.
The present invention adjusts flame height by the throughput that goes out that detects and adjust air tube, and is more accurate more and quick than the method for existing direct flame detection height, simplified checkout equipment, also do not need the circuit structure of complicated design.Owing to directly flame is not detected, the flame that lighter is lighted when having avoided test is to the influence of plastic components, tested this body structure of lighter there is not specific (special) requirements, applicability is wide, and require low to testing environment, adjust the position of adjusting nut by rotating ventilating shaft, the real-time adjusting that goes out throughput has improved efficient.
Improve and replenish as the further of said structure, the present invention also comprises any combination of following additional technical feature or these features:
Described clamp port is half circumferential notch, and when clamping plate were in running order, two semicircle breach of two clamping plate formed a clamping hole, and clamping hole is used for clamping lighter pin, and shape is consistent with air-out needle, good clamping effect.
The affixed clasp in the bottom of described anchor clamps holder, described clasp is arranged in the annular positioning groove on the ventilating shaft, is used for fixing ventilating shaft and anchor clamps holder, good positioning effect.
The inlet of described air guide channel is equipped with flexible pipe, docks with air-out needle better, when test airflow, reduces the leakage of gas.
