Дл  удержани  движущегос  бойка в одной плоскости имеютс  две пружины которые одновременно спужат токопроводами . Они изолированы от корпуса прибора и бойка. Дл  подъема бойка 3 служит захват 14 со стержн ми 15 и кнопка, К корпусу прибора прикреплен изме рительный блок, состо щий из трехстрелочного индикатора с микроэлектр двигателем 16, счетчика 17 сигналов усилител  на транзисторах 18, аккуму л торной батареи 19, кнопки сброса ; показаний стрелок индикатора 20 прочности , и счетчика 21, Выключатель 2J служит дл  ограничени  длительности электрического сигнала и тока, поступающего в измерительный блок только за врем  отскока бойка 3., Работа с прибором сводитс  к еле- дующему, При испытании прибор удерживают одной рукой за ручку 2 перпендикул рно к поверхности издели . Другой рукой за кнопку боек поднимают вверх и после выхода пружинного захвата из зацеплени  с головкой бойка под действием пружины 12 боек скользит вниз по направл ющему стержню 5, производит удар по ударнику 11 и отскакивает от него, При ударе возникают колебани  посто нного магнита 7 с пластинчатой пружиной бив катушке 8 индуктивности -И электрической цепи прибора воз-. никает электрический ток, который прид5дит в действие измерительный блок. Прибор позвол ет снизить трудозатраты на выполнение работ по контролю прочности материалов, причем данные испытаний можно сразу получить в единицах прочности с высокой точностью. Формула изобретени  Прибор дл  определени  прочности материалов, основанный i-ia принципе упругого отскока, включающий корпус с ручкой,боек с направл ющим стержнем, ударник с рабочей пружиной и измерительный блок, отличающийс  тем, что, с целью снижени  трудоемкости измерени  и повышени  точности, в бойке смонтированы пластинчата  пружина с посто нным магнитом и KaTsmiKa индуктивности, а в нижней части корпуса установлен св занный с измерительным блоком выключатель дл  отключени  катушки индуктивности, Источники информации, прин тые во внимание при экспертизе; 1,Новгородский М,А, Испытани  материалов, изделий.и конструкций М,, 1971, с, 207-210, 2,Патент США 3333461, кл, 73-88, 1967,To keep the moving hammer in one plane, there are two springs that simultaneously pull the conductor down. They are isolated from the device body and the striker. To raise the striker 3, there is a gripper 14 with rods 15 and a button, a measuring block is attached to the instrument case, consisting of a three-pointer indicator with a microelectrical motor 16, an amplifier counter 17 for transistors 18, a battery 19, a reset button; the readings of the arrows of the strength indicator 20, and the counter 21, the switch 2J serves to limit the duration of the electrical signal and the current entering the measuring unit only during the rebound of the striker 3. Work with the device is reduced to the next, When testing, hold the device with one hand 2 perpendicular to the surface of the product. With the other hand, for the button, the striker is lifted up and after the spring gripper leaves the engagement with the head of the striker under the action of the spring 12, the striker slides down along the guide rod 5, strikes the striker 11 and bounces off of it. Upon impact, a constant magnet 7 with a plate-like oscillations occurs spring beating coil 8 inductance -And the electrical circuit of the device as-- There is no electric current that will activate the measuring unit. The device allows to reduce labor costs for the performance of work to control the strength of materials, and test data can be immediately obtained in units of strength with high accuracy. The invention The device for determining the strength of materials based on the i-ia principle of elastic rebound, comprising a housing with a handle, a firing pin with a guide rod, a drummer with a working spring and a measuring unit, characterized in that, in order to reduce the labor intensity of measurement and increase accuracy, the striker has a permanent magnet spring and KaTsmiKa inductance mounted, and a switch connected to the measuring unit is installed in the lower part of the case to disconnect the inductor, the sources of information received in Imani under examination; 1, Novgorod M, A, Testing of materials, products and structures M, 1971, p. 207-210, 2, US Patent 3333461, Cl, 73-88, 1967, /;/;
