Diameter;Screw rod I described in short stud is threadedly coupled with the screw hole of rubber shock absorber groove side;Described in short stud
The outside wall surface of screw rod II has the external screw thread connecting with loop;With the tubular knot of step through-hole centered on the loop
Structure;The step through-hole is up big and down small structure;The small diameter bore of step through-hole and the screw rod of bolt are used cooperatively;
The large diameter hole of step through-hole and the nut kiss of bolt are matched;The top in step through-hole wall face has to be connected with screw rod II
The internal screw thread connect;The nut of the bolt is located in the large diameter hole of step through-hole, and the screw rod of bolt stretches out described
Step through-hole is threadedly coupled with the tapped through hole of the rubber shock absorber groove other side.
There are two groups of symmetrically arranged through-holes in the outside wall surface of the loop.
The bolt has nut and screw rod, and the top of the screw rod is polished rod, middle part is provided with for bolt fastening
Hexahedron, lower part is to the threaded rod that is threadedly coupled with the tapped through hole.
The center of screw rod II described in short stud has the hexagonal hole to cooperate with allen wrench.
The utility model proposes a kind of confined space in quick prepressing device, be arranged in the groove of glue vibration isolator,
By the cooperation of short stud, loop and bolt, quickly and effectively solve the problems, such as the precompressed of the rubber shock absorber useful space,
And the stroke that rubber shock absorber is effectively controlled when diesel engine acutely shakes, improves reliability and the longevity of rubber shock absorber
Life.
