Abstract

The invention provides a hidden door closer inner skeleton of an entrance door, the hidden door closer inner skeleton comprises an inner skeleton steel frame, a reinforcing mechanism is arranged at one end in the inner skeleton steel frame, and a plurality of tensioning mechanisms are arranged on the lower portion of the inner skeleton steel frame, according to the hidden door closer inner skeleton, the embedding friction force of the inner skeleton steel frame in a door body is enhanced through anti-skid teeth on the two sides of the inner skeleton steel frame, and embedding is more stable; the reinforcing plate is installed through the reinforcing mechanism in an inserted mode, welding operation is omitted, the problems caused by welding are avoided, the structure is simple, the size of the reinforcing plate can be adjusted, the width of the inner skeleton steel frame is adjusted through the multiple tensioning mechanisms, and therefore the inner skeleton steel frame can adapt to grooving width errors caused by inaccuracy during grooving.

Description

technical field [0001] The invention relates to the technical field of entry doors, in particular to the inner bone of a door closer of a concealed entry door. Background technique [0002] The entrance door is the first gate to enter the house, of course, its anti-theft performance is higher. Therefore, the entrance door is also called anti-theft door, and the entrance door is installed when most houses are completed. [0003] The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and released to automatically close the door. It has the function of a spring door, which can ensure that the door is closed accurately and timely to the initial position after being opened. . [0004] The hidden door closer needs to be embedded and installed on the top surface of the door leaf during installation. Because the interior of the entrance door is mostly hollow, it is necessary to install the hidden inner bone first. The exis...
