Abstract
The utility model discloses a buffer door closer. The buffer door closer comprises a slide assembly, a door closer body, and a closed shaft arranged on the door closer body. The slide assembly includes a supporting arm and a chute. One end of the supporting arm is hinged to the closed shaft, and the other end of the supporting arm, opposite to the closed shaft, is hinged to a slide block. The slide block is disposed in the chute and matches the chute in a sliding manner. One end of the chute is equipped with a buffer assembly, and the other end of the chute is equipped with a stop block used for preventing the slide block from sliding from the chute. The other end, opposite to the stop block, of the slide block is provided with a roller assembly. The stop block and the slide block are buckled via the roller assembly. The stop block is arranged in the chute and enables the supporting arm to keep unchanged in position when the door closer is stationary or slightly shakes. The other end, opposite to the stop block, of the chute is equipped with the buffer assembly, so impact forces between the supporting arm and a door are reduced when the door closer moves and returns, and thus the supporting arm and the door are prevented from being damaged due to excessive impact forces caused by returning.

Detailed description of the invention
Shown in Fig. 2, the amortization door closer of the present embodiment, comprise sliding assembly, door closer body 1 and be located at the closed axle on door closer body, described sliding assembly comprises support arm 21 and chute 22, described support arm 21 one end are hinged on closed axle, the other end of the relatively closed axle of described support arm 21 is hinged with slide block 4, described slide block 4 is located in chute 22 and is slidably matched with chute 22, described chute 22 one end are provided with Buffer Unit, the other end is provided with the scotch 5 that skids off chute 22 for anti-limited slip block 4, one end of described slide block 4 relative scotchs 5 is provided with roll wheel assembly, described scotch fastens by roll wheel assembly and slide block 4.
By adopting technique scheme, chute 22 is provided with scotch 5, scotch 5 is can be at door closer static or while slightly rocking, support arm 21 positions are remained unchanged, chute 22 is provided with Buffer Unit with respect to the other end of scotch 5, can be in the time of door closer returning movement, play the impact force reducing between support arm 21 and door, the excessive damage that causes support arm 21 and door of impact force while reducing because of return.
Described slide block 4 is provided with groove 6 with respect to scotch 5 one end, described roll wheel assembly comprises spring 73, bolt 72 and for the gripper shoe 71 of positioning sliding block 4, described bolt 72 is arranged on groove 6, and it is axially vertical with slide block 4 glide directions, described gripper shoe 71 is sheathed on bolt 72 successively with spring 73, described spring 73 one end and gripper shoe 71 are inconsistent, described gripper shoe 71 is provided with roller 8 near one end of scotch 5, described roller 8 coordinates with gripper shoe 71 is movable, described roller 8 is provided with buckling parts 52 away from a side of scotch 5, described buckling parts 52 slides and fastens with scotch 5.
