Pneumatic damping door closer
The invention provides a pneumatic damping door closer. The pneumatic damping door closer solves the problem that in the prior art, rotating parts such as a door or a window are not damped. The pneumatic damping door closer comprises a shell, one end of the shell is closed, a main piston in sealing contact with the shell is arranged in the shell, a closed air chamber is formed between the shell and the main piston, an upper cam and a lower cam which are matched with each other are arranged in the position, above the closed air chamber, of the shell, and an inner tooth through hole which is through up and down is formed in the middle of the lower cam. A damping cam meshed with the inner tooth through hole is arranged in the inner tooth through hole, and the upper surface of the damping cam is matched with the lower surface of the upper cam; a movable damping piston and grease are further arranged in the closed air chamber, a guide rod is arranged in the middle of the damping piston in a sealing fit mode, the upper end of the guide rod penetrates through the main piston and abuts against the lower surface of the damping cam, and the guide rod makes sealing contact with the main piston; the damping piston is provided with an oil passing structure for the grease to pass through.
本发明提出了一种气动阻尼闭门器，解决了现有技术中门或窗等旋转部件无阻尼的问题。该气动阻尼闭门器包括壳体，所述壳体的一端闭合，壳体内部设有与其密封接触的主活塞，所述壳体与主活塞之间形成密闭气室，所述密闭气室上方的壳体内设有相配合的上凸轮、下凸轮，所述下凸轮的中间位置开有上下贯通的内齿通孔，所述内齿通孔内设有与其啮合的阻尼凸轮，所述阻尼凸轮的上表面与上凸轮下表面相适配；所述密闭气室内还设有可移动的阻尼活塞和油脂，所述阻尼活塞的中间位置密封配合有导向杆，所述导向杆的上端贯穿主活塞并顶靠于阻尼凸轮的下表面上，所述导向杆与所述主活塞之间密封接触；所述阻尼活塞上开有供所述油脂通过的过油结构。
