Abstract: A door closer device for driving a door to a predetermined closed position includes an adjustment mechanism and a door closer which is integrated with the door. The adjustment mechanism includes a base, an adjusting plate and at least one fixing element, wherein the adjusting plate is stacked with the base and coupled with the door closer. The adjusting plate and the base respectively include at least one adjusting bore, and the adjusting bores are corresponding with each other. One of the adjusting bores includes a first limiting end and a second limiting end, and a first moving path is defined between the first and second limiting ends. The fixing element is disposed in the adjusting bores and can move along the first moving path to fix the adjusting plate on the base.

Abstract: An adjusting base for door closer includes a fixing member, an adjusting member, and at least one adjusting unit. The fixing member is configured to be fixed to a surface, and an upper surface of the fixing member is arranged with at least one protrusion. The adjusting member is arranged on the upper surface of the fixing member in an adjustable manner, and configured to be connected to a door closer. The adjusting member is formed with at least one adjusting hole for receiving the at least one protrusion. The at least one adjusting unit is movably arranged on the adjusting member and configured to abut against the at least one protrusion to adjust a relative position between the adjusting member and the fixing member.

Abstract: A door closer pivoted on a door at least includes a case and a piston. When the door is open, the door closer blocks a communicating hole of the case by an oil sealing ring of the piston to allow an oil filled in the door closer cannot flow through the communicating hole. As a result, the open door can be held in a predetermined position.
