Hydraulic hinge door closing device of adjustable positioning structure

Abstract

The invention discloses a hydraulic hinge door closing device of an adjustable positioning structure. The device comprises blades, a lower shell, positioning holes, an upper shell, a shaft core, a torsional spring, an inclined groove rolling way, a hydraulic damping mechanism, a piston rod, a rotating shaft sleeve, a check block, an end cover and a mounting hole; the upper shell and the lower shell are perpendicularly arranged, the blades are correspondingly fixed to the sides of the upper shell and the lower shell, the end cover is arranged on the top of the upper shell, the shaft core is arranged on the bottom of the end cover, the torsional spring is arranged on the outer side of the shaft core, the rotating shaft sleeve is arranged on the bottom end of the shaft core, and is clamped inthe lower shell, the inclined groove rolling way is arranged in the rotating shaft sleeve, and the hydraulic damping mechanism is arranged in the lower shell. According to the hydraulic hinge door closing device, the stable buffer reset function is achieved, due to mounting of the check block, the maximum returning angle of the blades can be controlled, according to the use condition, the check block mounting angle can be determined, contact between a door and the wall is avoided, and safety of the door and the wall is ensured.

Description

technical field [0001] The invention relates to the technical field, in particular to a hydraulic hinge door closer with an adjustable positioning structure. Background technique [0002] Hydraulic hinge, the full name of torsion spring hydraulic cushioning door closing hinge, is one of several hinges with door closer function commonly seen in the market; it is the first automatic door closing that appeared on the market instead of door closers One of the hinges, the current development of hydraulic hinges is relatively advanced, which can realize functions such as positioning, mute, and buffering. However, the installation of indoor doors now requires the installation of door suction devices. If hydraulic hinges can achieve this function, it will greatly improve practicality. sex. Therefore, we propose a hydraulic hinge door closer with an adjustable positioning structure. Contents of the invention [0003] The object of the present invention is to provide a hydraulic h...
