Electronic hydraulic door closer

Abstract

The invention discloses an electronic hydraulic door closer which comprises an external mechanism, a door stop solenoid valve and a rocker arm. The external mechanism comprises a stop plate, a mount plate and a stop plate limiter. The rocker arm of the door closer comprises a rocker arm body and a regulating arm connected in sequence; a rotation shaft and the stop plate with limit angle capable of being regulated rotationally are arranged on the rocker arm; the stop plate is provided with a limit notch, the limit notch is meshed with a steel ball in the rocker arm body, and the steel ball is abutted by a spring. As an oil circuit and an end cap of the door closer are connected into a whole, the integral structural design of the door closer is much more reasonable and compacter, the structure size of the door closer is reduced, maintenance and changing of the door closer are facilitated, and the door closer has higher specificity.

Description

technical field [0001] The invention relates to the technical field of door closers, in particular to an electronically controlled hydraulic door closer. Background technique [0002] The existing technology lacks an electronically controlled hydraulic door closer. The external mechanism of the door closer is unreasonably set, resulting in the door closer not being able to open and close smoothly, and prone to jamming. Therefore, it is urgent to develop a new type of external mechanism to optimize the structure of the door closer. Conventional solenoid valves cannot meet the special needs of door closers, and it is necessary to set up interfaces on the door closers to install solenoid valves. Because external ports need to be reserved, the structure of the door closers is relatively large, and the volume cannot be further reduced. Therefore, according to the closing To meet the actual needs of the door closer, develop a special door stop solenoid valve that can be quickly c...

Problems solved by technology

[0002] The existing technology lacks an electronically controlled hydraulic door closer. The external mechanism of the door closer is unreasonably set, resulting in the door closer not being able to open and close smoothly, and prone to jamming. Therefore, it is urgent to develop a new type of external mechanism, optimize the structure of the door closer

Conventional solenoid valves cannot meet the special needs of door closers, and it is necessary to set up interfaces on the door closers to install solenoid valves. Because external ports need to be reserved, the structure of the door closers is relatively large, and the volume cannot be further reduced. Therefore, according to the closing To meet the actual needs of the door closer, develop a special door stop solenoid valve that can be quickly connected and replaced with the door closer, reduce the number and volume of the door closer components, improve the compactness of the overall door closer, and improve the convenience of maintenance sex
