Damping door closer for side-hung door
The invention discloses a damping door closer for a side-hung door. The damping door closer comprises a connection base provided with a sliding groove and arranged on a door leaf and a buffering component arranged on a door pocket. The buffering component comprises a bottom plate, a cover, a damping oil cylinder, a first sliding part, a second sliding part, a swing part, a reset spring and a support. The damping oil cylinder and the support are fixed between the bottom plate and the cover. The swing part is provided with a rotation shaft, a guide column and a bent arm. The rotation shaft is connected between the bottom plate and the cover in a pivoting mode. A cylinder column of the damping oil cylinder abuts against the first sliding part. The reset spring is arranged between the second sliding part and the support. The bottom plate and the cover are each provided with first guide grooves and second guide grooves. The upper and lower surfaces of the first sliding part are each provided with a first protruding block capable of stretching into the corresponding first guide groove, and the upper and lower surfaces of the second sliding part are each provided with a second protruding block capable of stretching into the corresponding second guide groove. Two ends of a sliding groove are open, and the guide column of the swing part enables the swing part to swing so that the bent arm can make contact with the first sliding part or the second sliding part when stretching into the sliding groove of the connection base and moving in the sliding groove. Compared with the prior art, the damping door closer has the advantages of being ingenious in structure, apparent in buffered door closing effect, applicable to a home inner door and capable of opening the door completely and prolonging the service lives of parts effectively.
