JRJ News, July 21, 2025: Information from the State Intellectual Property Office (SIPO) shows that Zhejiang Aibo Security Technology Co., Ltd. has applied for a patent entitled "A Detection Device for Door Closer Shells", with the publication number CN120333265A and the application date in April 2025.

The patent abstract indicates that the invention discloses a detection device for door closer shells, relating to the field of door closer production and detection. It includes a bearing platform for supporting the door closer shell, where a central hole is formed on the side of the door closer shell. Bearing grooves adapted to the door closer shell are symmetrically formed on both sides of the top of the bearing platform, and an auxiliary unit for position correction and positioning of the door closer shell is arranged on the bearing platform. Protruding strips are symmetrically arranged on both sides of the bearing platform, circular grooves are formed at both ends of the protruding strips, and movable rods are slidably connected to the inner sides of the circular grooves. This detection device for door closer shells performs position correction and rapid positioning on the door closer shell in the bearing groove through the auxiliary unit, enabling the movable block to move quickly and insert the positioning column into the central groove. Thus, the center distance dimension value of the central groove can be quickly measured according to the direction of the indicator arrow with high accuracy.
