The utility model relates to a fast-
assembly fire-fighting extension telephone, which is characterized in that the installation in the XY plane direction is realized through the pre-connection of a leading-in column and a
buzzer, the leading-in column is conical, the leading-in column is more compact when being assembled downwards, an elastic buckle is pushed to deform at the same time, and when the
buzzer crosses the elastic buckle, the elastic buckle is reset to the upper part of the
buzzer to clamp the buzzer in a base. A sound cavity ring matched with the buzzer is arranged in the base, a press-fit column is arranged in the sound cavity ring to enable the buzzer to be assembled stably and avoid shaking of the buzzer, a tip is arranged at the end of the press-fit column, the tip deforms during press-fit to enable the buzzer to be installed in parallel, the sealing performance is better, sound is fuller, meanwhile, the consistency of products is better, and the reject ratio of the products is reduced. The base and the shell are connected through the clamping opening and the clamping block, limiting is carried out in cooperation with the limiting structure, shaking is avoided, screws are not needed in overall
assembly,
assembly is simpler and more convenient, production efficiency is improved, and material cost is saved. The hanging bracket and the
magnet are matched, so that the
handle is convenient to place and fix, and the use is more convenient.
