Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 3, the reaction nut capable of being quickly disassembled and assembled is mainly used for a bolt stretcher of a plate heat exchanger, and comprises a left half ring 1, a right half ring 2, a connecting block 3, a semicircular piece 4, a straight handle 5, a countersunk head bolt 6 and a bolt and nut assembly 7.
Threads matched with the long screw rods are arranged on the inner walls of the left half ring 1 and the right half ring 2, and the middle positions of the outer walls are respectively flattened along the axial direction and are used for being matched with a proper open-end wrench.
The utility model discloses a connecting block 3, including left semi-ring 1, right semi-ring 2, left semi-ring 1 and right semi-ring 2, the recess is processed along circumference respectively in a terminal surface middle part of left semi-ring 1 and a terminal surface middle part of right semi-ring 2, and when left semi-ring 1 and right semi-ring 2 enclosed into the annular shape, the recess on the left semi-ring 1 was relative with the groove position on the right semi-ring 2, formed the.
