Description
Изобретение может быть испопьзованс дл измерени диаметров деревьев при лесной таксации.The invention may be used to measure tree diameters during forest valuation.
Известно устройство дл измерени диаметров, содержащее две поворотные относ1ггельно общей оси измерительные ножки, упор посто нней длины, расположенный по биссектрисе угла раствора ножек, две т ги, шарнирно роединенные между собой и с измерительными ножками, и отсчетный узел .A device for measuring diameters is known, comprising two measuring legs pivotally relative to a common axis, an emphasis of constant length, located along the bisector of the solution angle of the legs, two rods connected to each other and with the measuring legs, and a reference node.
Недостатком известного устройства вл етс большое отклонение от пр мопропорциональной зависимости между измер емым диаметром и углом раствора ножек и, как следствие, невысока точность измерений.A disadvantage of the known device is a large deviation from the proportional relationship between the measured diameter and the solution angle of the legs and, as a result, the accuracy of measurements is low.
Цель изобретени - повыщение точности измерений путем получени близкой к пр мопропорниональной зависимости между измер емым диаметром и углом раствора измерггельных ножек.The purpose of the invention is to increase the measurement accuracy by obtaining a close to direct proportional dependence between the diameter and the measuring angle of the measuring legs.
Указанна цель достигаетс тем, тго в предлагаемом устройстве отсчетный узел выполнен в виде .угломерной шкатш, This goal is achieved by the fact that, in the proposed device, the readout assembly is made in the form of an velvet box,
установлениой на одной из ножек, и указател - на другой, а упором вл етс поверхность одной из т г, концентрична оси юс соединительного шарнира.on one of the legs, and the pointer on the other, and the stop is the surface of one of the legs, concentric to the axis of the joint hinge.
При таком выполнении упора его длина вл етс переменной. Она увеличивает- с при уменьшении измер емого диаметра и уменьшаетс при его увеличении, что и позвол ет повысить точность измерени .With this implementation of the stop, its length is variable. It increases with a decrease in the measured diameter and decreases with its increase, which makes it possible to increase the measurement accuracy.
На фиг. 1 и 2,изображено предлагаемое устройство дл измерени диаметров в сложенном состо ш в двух проекци х; на фиг. 3 - то же устройство при проведений : HSMepejiHfl,FIG. Figures 1 and 2 illustrate the proposed device for measuring diameters in a folded state in two projections; in fig. 3 - the same device when conducting: HSMepejiHfl,
Устрсйство содержит две раздвижные ножки 1 и 2, которые могут поворачиватьс относительно общей оси 3. Ножки дополнительно соединены Тмежду собой т гами 4 и 5, образуют вместе с участками ножек шарнирный параллелограмм . The device contains two sliding legs 1 and 2, which can rotate relative to a common axis 3. The legs are additionally connected. Each of them is connected with legs 4 and 5, and together with the legs they form a hinged parallelogram.
