Abstract

The invention relates to a concealed type door closer chute opening stopping structure which comprises a door closer assembly, a chute stopping assembly and a driving arm. The door closer assembly is provided with a damping pivot. The chute stopping assembly comprises a chute, a sliding block and a stopping blocking component for enabling the sliding block to stop at one certain position. The sliding block is arranged in the chute in a sliding mode, the stopping blocking component is fixedly arranged in the chute, the sliding block is rotationally connected with one end of the driving arm, and the other end of the driving arm is fixedly connected with the damping pivot. The stopping blocking component comprises a fixing block, an elastic sheet, an adjusting sheet and a locking screw. The fixing block, the elastic sheet and the adjusting sheet are fixed in the chute through the locking screw. The elastic sheet in a cantilever shape is arranged on the top of the fixing block. The cantilever portion of the elastic sheet points to the sliding block, and the portion, corresponding to the sliding block, of the cantilever portion of the elastic sheet is provided with a stopping groove. The adjusting sheet is adjustably arranged on the top of the elastic sheet in the length direction of the elastic sheet. One end of the adjusting sheet extends to the back face of the stopping groove. The concealed type door closer chute opening stopping structure has the advantages that stopping resistance is adjustable and the service life of the elastic sheet is long.
