The invention relates to the field of door closers, and discloses a door closer with a spring easy to replace, which comprises a door closer shell, a first piston, a second piston and a rack are sequentially arranged in a middle channel of the door closer shell from left to right, and first sealing covers for sealing the middle channel are arranged on two sides of the door closer shell; a rocker arm gear meshed with the top of the rack is arranged on the door closer shell, and an oil channel located above the middle channel is formed in the door closer shell. According to the door closer with the spring easy to replace, the spring is arranged at the lower channel of the independent middle channel, the middle single channel provided with the first piston, the second piston and the rack is filled with hydraulic oil, and a third piston is arranged for blocking, so that the spring can be taken out from the lower channel to be replaced only by disassembling a second sealing cover on the left side of the door closer shell; the trouble that the door closer needs to be filled with hydraulic oil again before and after the spring is replaced is avoided, and the spring replacement efficiency is improved.
本发明涉及闭门器领域，且公开了一种易于更换弹簧的闭门器，包括闭门器壳体，闭门器壳体的中间通道内由左至右依次设有第一活塞、第二活塞、齿条，且闭门器壳体的两侧设有密封中间通道的第一封盖，闭门器壳体上设有与齿条顶部啮合的摇臂齿轮，闭门器壳体内开设有位于中间通道上方的油液通道。该易于更换弹簧的闭门器，通过弹簧设于独立中间通道的下位通道处，而液压油充满于装有第一活塞、第二活塞、齿条的中间单通道内，并设置第三活塞阻隔，从而只需拆卸闭门器壳体左侧的第二封盖，即可从下位通道内取出弹簧进行更换，无需在更换弹簧前后，需要重新向闭门器内充满液压油的麻烦，提高了弹簧更换的效率。
