Loudspeaker device convenient to maintain

Abstract

A loudspeaker device convenient to maintain, disclosed by the present invention, comprises a top seat composed of a fixing part and a locking part and an insertion part equipped with a loudspeaker at the bottom, the top end face of the fixing part is equipped with a fixing plate, and the fixing plate extends towards the left and right ends of the fixing part. Fixing holes are respectively arranged in the extended segments at the two ends of the fixing plate, bolts are arranged inside the fixing holes, and an insertion cavity extending downwards is arranged in the middle part of the fixing part. The bottom of the insertion cavity penetrates the locking part, the top wall of the insertion cavity is equipped with a spacer block, and the fixing parts at the left and right sides of the spacer block are both equipped with the first sliding cavities. The bottoms of the first sliding cavities are equipped with the cavities, the second sliding cavities are arranged in the locking part at the bottoms of the cavities, and the first sliding blocks are arranged inside the first sliding cavities. The plug pin holes are arranged at the inner sides of the bottoms of the first sliding blocks, the bottoms of the first sliding blocks at the outer sides of the plug pin holes are equipped with the first toothed chain parts, and the gear wheels in toe joint with the bottoms of the first toothed chain parts are arranged inside the cavities. The second sliding blocks are arranged inside the second sliding cavities, the locking rods which penetrate the locking part and are in slip cooperative connection are arranged at the outer sides of the second sliding blocks, and the sides of the second sliding blocks far away from the locking rods are equipped with the beveled end parts.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker device that is easy to maintain. Background technique [0002] In some public places with a large flow of people, such as (hospitals, schools, railway stations, etc.), loudspeaker equipment is often used for sound amplification. Existing loudspeaker equipment is generally fixed on the top wall by screws or screws. When maintenance is required, it needs to be installed and disassembled by tools. It has problems such as difficult replacement and slow replacement speed, which seriously affects work efficiency. At the same time, the contact piece of the existing loudspeaker equipment leaks outside, which increases the risk of electric shock during maintenance and has a relatively large potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a loudspeaker device that is easy to maintain...
