Description

Quick-connection type loudspeaker tube Technical Field The utility model relates to the technical field of loudspeaker tube assembly, in particular to a quick-connection loudspeaker tube. Background The loudspeaker tube is a device which converts electric signal energy into sound energy and can radiate sound energy to a limited space or an outdoor space, commonly called as a loudspeaker, and the traditional loudspeaker tube is produced in a welding mode in structural design, so that the loudspeaker tube needs to be replaced entirely when being uniformly distributed and damaged, the damaged local position is difficult to be replaced singly, the maintenance cost is increased, and when the loudspeaker tube is maintained and disassembled, all parts inside the whole loudspeaker tube are required to be disassembled completely, so that the disassembling and assembling speed of the loudspeaker tube is obviously reduced, and the maintenance and disassembling efficiency of the loudspeaker tube is reduced. The present utility model has been made in view of the above problems. Disclosure of Invention The utility model provides a quick-connection type loudspeaker cylinder, which solves the problems in the use process in the prior art. The quick-connection type loudspeaker tube comprises a loudspeaker tube bottom cover, wherein a sound channel cover plate is arranged on one side of the loudspeaker tube bottom cover, a plug-in part is fixedly connected to one side of the loudspeaker tube bottom cover, one side of the plug-in part is plugged into the sound channel cover plate, clamping grooves are formed in two sides of the plug-in part, a locking groove is formed in one side of an inner cavity of the clamping groove, a sliding hole is formed in one side of the inner cavity of the locking groove, a positioning pin is slidably arranged in the inner cavity of the sliding hole, one end of the positioning pin is fixedly connected with a spring, one end of the spring is fixedly connected to the inner wall of the sliding hole, locking blocks matched with the clamping groove and the locking groove are fixedly connected to two sides of the inner cavity of the sound channel cover plate, and a positioning groove matched with the positioning pin is formed in one side of the locking block.
