The invention relates to the related field of hardware door stopper structures and discloses a gravity type door closer. The gravity type door closer comprises a door body and a wall body, wherein a driving bevel gear used for opening and closing the door body is fixedly installed on one side of the top end of the door body, and one end of the driving bevel gear is movably installed on the wall body; a driven bevel gear engaged with the driving bevel gear is movably installed on one side of the wall body, and a fixed wire clamping disc is fixedly installed at one end of the driven bevel gear. The weight increasing body is arranged in the wall body and is pulled to move up and down through the pulling rope, so when the door body is opened, the weight increasing body is lifted in a labor-saving manner in a movable pulley manner through rolling of the fixed wire clamping disc, and further, when the weight increasing body falls down, the door needs to be closed, gravity of the weight increasing body can be completely injected to the driven bevel gear through the adjusting gear, so the driven bevel gear rotates to close the door body, and finally purposes of labor-saving opening and self-gravity door closing are achieved.
本发明涉及五金门吸结构相关领域，且公开了一种重力式闭门器，包括门体和墙体，所述门体的顶端一侧固定安装有用于门体进行开合的驱动斜齿轮，且驱动斜齿轮的一端与墙体活动安装，所述墙体的一侧活动安装有与驱动斜齿轮啮合的从动斜齿轮，且从动斜齿轮的一端固定安装有固定夹线盘。本发明通过在墙体中设置有增重体，并通过牵引绳牵引增重体上下运动，因而当门体打开时，通过其固定夹线盘的收卷实现其增重体通过动滑轮形式实现省力抬起，进一步的，在其增重体下落时即需要关门状态，其增重体的重力会通过调节齿轮全部注入至从动斜齿轮上，从而实现从动斜齿轮转动实现门体的关闭，最终实现省力开启及自重力关门的目的。
