Convenient-to-maintain speech device

Abstract

The invention provides a convenient-to-maintain speech device and relates to the field of speech devices. The convenient-to-maintain speech device comprises a machine case, wherein the bottom of the machine case is fixedly connected with a support column; and one end, far away from the machine case, of the support column is fixedly connected with a fixed plate. According to the convenient-to-maintain speech device, the target of facilitating separation of a baffle plate from a clamping block through drive of a pulling handle is achieved through rotating the pulling handle; through cooperationof a connecting rod, a second reinforcing block and a first reinforcing block, the target of facilitating separation and removal of the right side of a cover plate from the machine case through pulling the connecting rod towards the right is achieved; and through cooperation of a handle, a motion lever and a bolt, the target of driving a slot to be separated from the inside of the slot to remove the left side of the cover plate from the machine case through pulling the handle is achieved, so that the problem that inconvenience is brought for maintenance work due to the fact that an existing speech device is inconvenient to remove in use is solved.
