Problems solved by technology

Since the injected glue is polyurethane foam, the reaction speed is extremely fast. In addition, the installation part of the plastic plug is a spherical surface. It is difficult to press the plug into the injection hole by hand, and often the plug has not been pressed into the injection hole. , the polyurethane foam has foamed and flowed out from the injection hole, and there is a phenomenon of waste

Abstract

The invention relates to the technical field of railway signal systems, in particular to an installation device for a plastic seal for a styrofoam injection hole of an antenna element shell. The installation device comprises a handle, a press shank and an installation head; the installation head is fixed to one end of the press shank and is of a U-shaped structure, and the middle of the inner sidesurface of the U-shaped structure is provided with a clamping groove; and a seal cover of the seal can slide into the clamping groove from an opening part of the U-shaped structure. According to theinstallation device, the situation that a seal is pressed into a styrofoam injection hole with hands is avoided, seal installing operation and seal separation operation after installing are both veryconvenient, and in addition, by arranging the clamping groove, the seal cover can be stably held and is not prone to disengagement.

Description

technical field [0001] The invention relates to the technical field of railway signal systems, in particular to a mounting device for plastic sealing of glue injection holes of antenna unit shells. Background technique [0002] There is a glue injection hole on the shell of the antenna unit of the railway signal system. When insulating and sealing the shell cavity, it is necessary to inject polyurethane foam into the shell cavity through the glue injection hole, and then press the plastic plug into the glue injection hole by hand. The hole seals it. Since the injected glue is polyurethane foam, the reaction speed is extremely fast. In addition, the installation part of the plastic plug is a spherical surface. It is difficult to press the plug into the injection hole by hand, and often the plug has not been pressed into the injection hole. , the polyurethane foam has been foamed and flowed out from the injection hole, and there is a phenomenon of waste. Contents of the inv...
