Abstract

The invention discloses a novel elastic device body compacting device, which comprises a compression screw, a gland, a shell and an elastic washer, wherein the compression screw is arranged on a bracket through a release nut, the elastic washer is arranged in the shell, the gland is arranged on the elastic washer, the bottom of the compression screw is abutted to the gland, the gland is in a concave shape with an upper edge, the central concave inner diameter of the gland is matched with the compression screw, the concave outer diameter is matched with the inner diameter of the shell, the outer diameter of the upper edge is larger than the inner diameter of the shell, the center of the concave bottom is provided with a through hole, the outer side of the gland is provided with a positioning hole, the lower part of the compression screw is provided with a running-through T-shaped through hole along the axis and the diameter, the T-shaped through hole and the through hole in the bottom of the gland constitute an air flue, the side part of the shell is provided with a positioning cavity, and when the gland is contacted with the shell, positioning pins can be arranged in the positioning cavity and the positioning hole; and the bottom of the shell is provided with an oil hole. According to the device disclosed by the invention, because a compaction stroke limit is set, the compression force is better controlled, the compaction state can be maintained, the installation is facilitated, a region of bypassed oil does not exist, and air blockage can not be produced.

Description

technical field [0001] The invention relates to a transformer part, in particular to an elastic pressing device for a body. Background technique [0002] The existing elastic pressing device for the device body has the following defects: the pressing stroke is unlimited, the state after pressing cannot be maintained, and the gas is stored inside. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elastic pressing device with reasonable structure for the deficiencies of the prior art. [0004] In order to solve this technical problem, the present invention provides a novel body elastic pressing device, which includes a pressing nail, a gland, a casing, and an elastic washer. The gland is placed on the elastic washer, and the bottom of the pressure nail is against the gland. The gland is concave with an upper edge. The outer diameter is larger than the inner diameter of the shell, a through hole is provided a...
