Abstract

Изобретение предназначено дл соединени деталей ст гивающим элементом (болтом) и относитс к машиностроению. Цель изобретени - улучшение удобства эксплуатации за счет сокращени времени на установку силового механизма. Устройство состоит из ст гивающего элемента, на котором между гайкой 2 и деталью установлена винтова пара из втулок 4 и 5 и силового механизма. При вращении ходового винта 19 рычаги 10 и 11 сдвигают втулки 4 и 5 и раст гивают их винтовой парой, ст гивающий элемент. 2 ил.The invention is intended to connect parts with a clamping element (bolt) and relates to mechanical engineering. The purpose of the invention is to improve ease of operation by reducing the time to install the force mechanism. The device consists of a tightening element, on which a pair of screws from sleeves 4 and 5 and a force mechanism is installed between the nut 2 and the part. As the lead screw 19 rotates, the levers 10 and 11 shift the sleeves 4 and 5 and stretch them with a screw pair, the tightening element. 2 Il.
