The invention discloses a hollow door closer. The hollow door closer comprises a door closer shell, a spring installation area and a rotary disc installation area are arranged in the door closer shell, an auxiliary spring is installed in the spring installation area, a clamping piece is arranged at the extending end of the auxiliary spring, and a fixing clamping groove is formed in the rotary disc installation area. A positioning ball is arranged at one end of a traction steel wire rope and installed on a clamping groove, then the traction steel wire rope is wound on a rotary disc, the clamping piece is arranged at one end of the auxiliary spring and installed on a clamping piece hole in the rotary disc, then the whole rotary disc is installed in the door closer shell, a door closer bottom cover is installed on the door closer shell, finally, and a groove of the door closer bottom cover bottom cover sleeves an anti-falling piece to fix the door closer shell. The installation steps are simple, time and labor are saved in the installation process, the work intensity of installation personnel is reduced, and the production efficiency is improved.
本发明公开了一种中空门闭门器，包括闭门器外壳，所述闭门器外壳的内部设置有弹簧安装区和转盘安装区，所述弹簧安装区的内部安装有助力弹簧，所述助力弹簧的伸出端设置有卡位片，所述转盘安装区的内部设置有固定卡槽。本发明的牵引钢丝绳的一端设有定位珠，定位珠安装在卡槽上，然后把牵引钢丝绳卷在转盘上，助力弹簧的一端设有卡位片，卡位片安装在转盘上的卡位片孔上，然后把整个转盘安装在闭门器外壳里面，把闭门器底盖安装在闭门器外壳上，最后把底盖防脱片套在闭门器底盖的槽里，对闭门器外壳进行固定，安装步骤比较简单，安装过程也比较省时省力，降低了安装人员的工作强度，提高了生产效率。
