| titleOfInvention | An anti-blocking armless hydraulic door closer with locking function |
| abstract | The invention relates to the field of door closing equipment, in particular to an anti-blocking armless hydraulic door closer with a locking function. It includes a door frame connecting body and a door body connecting body; the door body connecting body includes a shell and a core body; the core body includes an outer sleeve, an upper shaft, a piston device and a lower shaft; the piston device is provided with a one-way valve plate; the bottom center thread of the lower shaft is equipped with a speed regulating valve needle, the top of the speed regulating valve needle is provided with an oil passage, and a magnetic suction filter device is arranged in the oil passage. The magnetic suction filter device of the present invention can adsorb and filter the metal debris in the hydraulic oil, thereby ensuring the smooth flow of the oil passage; at the same time, by adjusting the communication area between the triangular oil passage and the oil passage, the flow rate of the hydraulic oil can be adjusted. Keep the door body at a suitable closing speed. At the same time, it can realize the three door closing stages of fast-slow-fast door body, which can not only avoid personnel pinching caused by fast door closing, but also realize the locking function of the door body. |
