[0022] Reference Figure 1-8 As shown, the utility model provides a technical solution: a fixing structure of a building call panel, comprising a panel body 1 and a mounting box 2, a mounting tube 3 is fixedly connected to one side of the panel body 1, four inclined arc plates 5 are fixedly connected to the inner wall of the other end of the mounting tube 3, a partition 6 is fixedly connected to the inner wall of the mounting box 2, and four arc-shaped slide grooves 7 are opened on the surface of the partition 6, a driving component is arranged below the arc-shaped slide groove 7, and a turntable 8 is fixedly connected to the upper end of the driving component, and four fixing bolts 9 are fixedly connected to the surface of the turntable 8, and the fixing bolts 9 It is slidingly connected to the surface of the inclined arc plate 5. When the panel body 1 needs to be quickly installed, first insert the installation tube 3 on the panel body 1 into the installation box 2, and then drive the turntable 8 to rotate through the driving assembly. When the turntable 8 rotates, it drives the four fixing bolts 9 to rotate in the arc-shaped slide groove 7. As the fixing bolts 9 slide on the surface of the inclined arc plate 5, the squeezing force of the fixing bolts 9 on the inclined arc plate 5 will become greater and greater, thereby quickly fixing and installing the panel body 1. The opposite operation can quickly disassemble the panel body 1.
