Description

Mounting bracket of door closer

Technical Field

The utility model relates to a technical field of door, specifically speaking, the utility model relates to a mounting bracket of door closer.

Background

Most of traditional door leaves are of solid structures, and on the basis of the solid structures, the traditional door closer for installing the door at the present stage is directly fixed by screws, and other components are not used for auxiliary installation; the door closer is directly fixed through screws, and the installation is relatively firm. However, for the door leaf with the hollow extrusion structure, the nail holding force is lower than that of a solid door leaf, and the door closer is directly fixed by screws, so that the phenomenon of infirm installation of the door closer can occur.

Chinese patent application No. CN 201020238302.X discloses a parallel mounting bracket, which comprises a free end and a fixed end for fixing the parallel mounting bracket, wherein the middle part of the free end is provided with a mounting hole, and the middle part of the fixed end is provided with a central hole and at least one auxiliary hole; the free end and the fixed end are both arc-shaped; the parallel mounting bracket has an axis, and the mounting hole and the central hole are positioned on the axis of the parallel mounting bracket; the number of the auxiliary holes is four; when the number of the auxiliary holes is more than three, the distance between each auxiliary hole and the central hole is equal, and the distance between every two adjacent auxiliary holes is equal; a door closer comprises a door closer main body provided with an output shaft, an arm assembly and a parallel mounting bracket, wherein the arm assembly comprises a fixed arm and a connecting arm which are hinged at the end parts; the parallel mounting bracket comprises a free end and a fixed end for fixing the parallel mounting bracket, the middle of the free end is provided with a mounting hole, and the middle of the fixed end is provided with a central hole and at least one auxiliary hole arranged around the central hole; the parallel mounting bracket is hinged with the other end of the fixed arm at the mounting hole; the other end of the connecting arm is connected with the output shaft; the free end and the fixed end of the parallel mounting bracket are both arc-shaped; the parallel mounting bracket has an axis, and the mounting hole and the central hole are positioned on the axis of the parallel mounting bracket; the number of the auxiliary holes at the fixed end of the parallel mounting bracket is four; when parallel mounting bracket stiff end auxiliary hole figure is more than three, every auxiliary hole with centre bore distance homogeneous phase equals, and distance homogeneous phase equals between every two adjacent auxiliary holes.

In the door closer installed in the patent, the fixed end of the parallel installation bracket is fixed on the door frame through a central hole and two auxiliary holes, and the parallel installation bracket, the connecting arm and the fixed arm are connected; the added parallel mounting bracket enables one end of the fixed arm which is originally directly connected to the wall to be connected to the parallel mounting bracket, so that the included angle between the fixed arm and the connecting arm is increased, the rotation angle of the output shaft is increased, and the spring in the door closer main body is further compressed, so that the door closing force is improved; however, when the parallel mounting bracket is applied to the door leaf of the hollow extrusion type structure, the parallel mounting bracket needs to receive a large elastic force from the spring, a side surface of the door leaf needs to receive a large pressure, and the service life of the door closer on the hollow extrusion type door leaf is short.
