Description

Hand-held explosion-proof intercom Technical Field The utility model belongs to the technical field of interphones, and particularly relates to a handheld explosion-proof interphone. Background The interphone is a portable two-way communication device, which uses radio signals to propagate in the air to realize point-to-point or point-to-multipoint instant communication, and mainly comprises a shell, a host, a battery, a belt clip, a seat charger, an antenna and other parts. At present, in the use process of the explosion-proof interphone, an operator generally completes communication through the handheld interphone, when the explosion-proof interphone is not used, the explosion-proof interphone is hung on a chest or a waist through a belt clip, but in the use process, the interphone is taken through the holding power of the hands of the operator, and in addition, a mechanism for fixing the interphone on the hands is not provided, so that the explosion-proof interphone is easy to fall off when being taken and used. To this end, the utility model provides a handheld explosion-proof intercom. Disclosure of utility model In order to make up the deficiency of the prior art and solve the problem that the handheld interphone is easy to drop, the utility model provides the handheld explosion-proof interphone. The handheld explosion-proof interphone comprises a body, wherein a fixing seat is fixedly connected to the back side of the body, a connecting column is installed on the fixing seat, a binding band is installed on the connecting column, the end portion of the binding band is connected with a band collecting roller installed inside the body, the band collecting roller is rotatably connected with the body, one end of the band collecting roller is provided with a slot, an inserting block is slidably connected with the slot, the end portion of the inserting block is fixedly connected with a rotating shaft rotatably connected with the body, the end portion of the rotating shaft is fixedly connected with an operating block, and a limiting piece used for limiting the band collecting roller is connected to the outer side face of the rotating shaft, so that the interphone is conveniently bound on a hand through the binding band, and the interphone is prevented from falling.
