As we all know, the seats used in the auditorium or movie theater will automatically flip to the vertical position when people leave, so that there is a large aisle between the rows and rows of seats for people to move around. In the prior art, this theater chair is turned over by the following method: a fixed shaft is provided between the two chair legs, and a bearing seat combined with the fixed shaft is provided on each side of the bottom of the seat, Make the seat rotate around the fixed axis. At this time, we are very particular about the installation of the bearing seat, and the method of fixing it on different floors is different. So what is the method of fixing the cinema seat bearing seat on different plates?
 
1. Cement floor: directly use a percussion drill to open the hole and embed the pull-explosive nut;
 
2. Tiles and marbles: first use a glass drill to drill holes to the cement floor, then use an impact drill to drill holes, and bury screws in advance;
 
3. Wooden floor: After drilling with a wood drill, the impact drill will be used to embed the pull-out nut;
 
4. Steel frame and steel plate: first drill the 3-4mm small hole with an electric drill and then directly install the special self-tapping screws. If the floor is 30 ~ 40mm thick, you can directly use the special self-tapping screws and fix it directly.
 
In summary, it is not difficult to find that the fixing methods used by similar floors are basically the same. For example, marble and ceramic tiles are both slate materials. I believe that everyone now knows how to fix cinema chairs.
