Detailed Description

As an embodiment of the utility model, as shown in fig. 1-4, a combined door closer comprises a mounting component, the mounting component is arranged on a door frame 1, the door frame 1 is elastically hinged with a door 2, in general, the door frame 1 and the door 2 are connected by a hinge, the hinge is also called a hinge, the existing hinges capable of realizing automatic closing of the door 2 on the market comprise a hydraulic hinge and a spring hinge, the utility model is described by the spring hinge, when the spring hinge is used, because the deformation characteristic of the spring can lead the door 2 to have larger impact force to a certain extent when the door 2 is closed, the door 2 and the door frame 1 with the spring hinge can generate impact damage to different extents after long-time use, the utility model is provided with a supporting plate 10 on the mounting component, the supporting plate 10 is rotationally connected with a swinging rod 11, a spring cylinder 13 is arranged on the supporting plate 10, a user can select a proper elastic coefficient according to the weight of the door 2, the fixed end of the spring cylinder 13 is fixedly connected with the supporting plate 10, when the door 2 is in contact with a damping wheel 14 which is connected with the door frame 2 by the rotating spring wheel 14, and the swinging rod 11 is contacted with the elastic wheel 14 or the elastic wheel 12 when the door 2 is in contact with the rotating plate 12, thereby the surface of the door 2 is contacted with the elastic wheel 12, the damping wheel 12 is contacted with the door 2 or the swinging rod is contacted with the elastic wheel 11, and the damping wheel 12 is contacted with the door 2 to the surface of the door 2 to have a certain impact force when the elastic wheel 12 is contacted with the door 2 or the door 2 is contacted with the elastic wheel 12, thereby further reducing the speed of closing the door 2 under the dual action of friction and elastic force.

In a preferred case of this embodiment, the door 2 is fixedly connected with a damping bar 4, and the damping wheel 12 is located on the swing path of the damping bar 4. The friction contact between the damping strip 4 and the damping wheel 12 can improve the friction force between the damping strip 4 and the damping wheel 12, and the elastic rotation torque between the damping wheel 12 and the swing rod 11 is matched, so that the speed of the door 2 when being closed can be further reduced, the impact force applied to the door 2 and the door frame 1 when being closed is reduced, and the service lives of the door frame 1 and the door 2 are prolonged.
