Product Description
Hydraulic hinges for heavy doors, full name torsion spring hydraulic cushion closing hinge, is one of several hinges with door closer function commonly found in the market; it is one of the earliest automatic closing hinges that appeared in the market instead of door closer.
▲ Working principle:
(1) power: when the hinge is opened, the torsion spring built into the hinge center shaft twists and deforms to produce a reaction closing force;
(2) hydraulic pressure: hinge axis built-in a small cylinder, with oil back to the small hole of the piston sliding back and forth along the cylinder wall to generate blockage, that is, hydraulic pressure;
(3) cushioning: when closing the hinge, the pressure generated by the torsion spring twisting forces the hydraulic oil in the cylinder to flow through the small hole in the piston, because the oil hole aperture is small, resulting in a slow flow rate of oil, hindering the torsion spring to close the door quickly, i.e., cushioning.
▲ Advantages:
(1) Easy to install: just install it like an ordinary hinge, avoiding the damage to the door or wall caused by installing the traditional door closer;
(2) Adjustable closing speed: users can adjust the closing speed according to their needs;
(3) With door stop: it can be stopped after a certain angle (usually about 70-80 degrees), which is convenient for daily use.
(4) Good closing buffer effect, no obvious collision.
Our Advantage
▲ Set the door closer, traditional hinge, door top, foot door stop function in one, 1 piece of hinge top 4 hardware.
▲ Angle range control: Invisible door hydraulic hinge has different functional performance in different angle range.
Within the range of 180°~80°, the door can be positioned at will and will not spring back;
80 ° ~ 30 ° range, the door will carry out rapid closing action;
In the range of 30°~15°, the hydraulic pressure intervenes to slow down the closing speed of the door;
In the 15°~0° range, some are designed to close quickly so that the door can be jammed into the lock, while others are designed to close slowly so that the door closes gently. This design makes the use of the door more flexible and convenient.
▲ Stable performance and long service life: compared with ordinary door closers, hydraulic door hinge performance is more stable, longer service life. Ordinary door closer is prone to oil leakage, resulting in mechanical performance degradation and shortened service life, while the hydraulic door closer hinge never leaks oil, stable and reliable performance.
▲ Solve the problem of hydraulic hinge oil leakage: to ensure that there will be no oil leakage in the process of use, special oil seals on the top to eliminate oil leakage.
▲ Beautiful and convenient installation: the installation process of hydraulic door closer is similar to that of ordinary hinges, which is easy to install and does not damage the overall beauty of the door. External door closer may cause damage to the door during installation, while the installation process of hydraulic door closer hinge will not cause damage to the door, maintaining the integrity of the door.
▲ Adjustable closing speed: The closing speed of the hydraulic closing hinge can be realized by simple adjustment, while the ordinary door closer needs to be adjusted at the head of two screws, which is difficult to control. This feature allows users to easily adjust the closing speed of the door as needed
▲ Safe to use: hydraulic door hinge has a functional design to absorb the impact, when the door is hit by a strong external force, you can reduce the human security risks, but also to protect the door frame from strong impact damage, thus prolonging the service life. Thus prolonging the service life.
Hydraulic hinges for heavy doors not only has a flexible angle control function, but also has a stable performance, long service life, beautiful and convenient installation, closing speed can be adjusted as well as the use of safety and other characteristics. Applicable to government departments, enterprises and public institutions, office buildings, hotels, hotels, residential housing and other fields.
