Novel door closer and connecting rod applied to novel door closer
The invention discloses a novel door closer. The novel door closer comprises a shell, an insertion hole is formed in the shell, a piston column is arranged in the insertion hole in a clearance fit mode, a blind hole is formed in the piston column, and a compression spring is installed on the blind hole. Parallel teeth are arranged on the piston column, a shaft is arranged in the shell, a gear matched with the parallel teeth is fixed to the shaft, a mounting hole is formed in the piston column, a sealing ball is arranged in the mounting hole, a blocking protrusion is arranged on a second hole,and a long clamping slot is formed in the shaft. A connecting rod comprises a rod body and the mounting hole formed in the rod body. The mounting hole is provided with a bayonet, and the cross sectionof the bayonet is matched with the cross section of the long clamping slot. The contact area between the shaft and the connecting rod can be increased, the installation of the connecting rod is convenient, the contact area between the shaft and the connecting rod is increased, the wear on the contact surface of the shaft and the connecting rod is reduced, the service life of the door closer can be prolonged, the accuracy of closing the door is greatly increased, the situation that a gap is generated due to the wear of the shaft connecting end when the door is closed is avoided, and the noveldoor closer is worthy of popularization and application.
本发明公开了一种新式闭门器，包括壳体，壳体内设有插接孔，插接孔内间隙配合有活塞柱，活塞柱上开盲孔，盲孔上安装有压缩弹簧，活塞柱上设有平行齿，壳体内设有轴杆，轴杆上固定有与平行齿配合的齿轮，活塞柱上开有安装孔，安装孔内设有密封球，孔二的上设有阻挡凸部，轴杆上设有长卡槽。一种连杆，包括杆体及开在杆体上的安装孔，安装孔上开有卡口，卡口的截面与长卡槽的截面匹配。本发明能够使的轴杆与连杆的接触面积增大，不仅便于对连杆的安装，而且能够增加轴杆与连杆的接触面积，降低轴杆与连杆接触面的磨损，从而不仅增加闭门器的使用寿命，还能够大大增加关门的精度，避免由于轴杆连接端磨损而造成关门时有缝隙产生，值得推广应用。
