[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] See also Figure 1-Figure 5A display control module for building access control includes a shell 10, and a receiving groove 100 is arranged on the left and right sides of the shell 10. The rear side of the receiving groove 100 is opened, and a bracket 20 is arranged in the receiving groove 100. The bracket 20 can rotate relative to the shell 10 so that the lower end of the bracket 20 swings to the rear of the receiving groove 100. The upper end of the bracket 20 is rotatably connected to the shell 10. The upper end of the receiving groove 100 is provided with a plurality of positioning grooves 112 in a circular array along the rotation axis of the bracket 20. The upper end of the bracket 20 is provided with a positioning protrusion 220 that can be embedded in any one of the positioning grooves 112.

[0019] Based on the above embodiment, when the bracket is adjusting the support angle, the positioning protrusion will disengage from the original positioning groove and then enter the next positioning groove. When the positioning protrusion is located in the positioning groove, the bracket is in a locked state. If the angle of the bracket needs to be adjusted again, an external force needs to be applied to the bracket to drive the bracket to rotate relative to the shell.
