Hinge with damping

Abstract

The invention relates to a hinge with damping. The hinge comprises a connecting core rod and two vane assemblies, wherein both the two vane assemblies are connected with articulated pipes, and the connecting core rod respectively penetrates through the articulated pipes on the two vane assemblies; a damping sleeve is fixedly arranged in each articulated pipe, the connecting core rod is sleeved in the articulated pipes through the damping sleeves and is in interference fit with the damping sleeves. As the damping sleeves are adopted, damping oil is not needed, and the problem of oil leakage is solved. As the damping sleeves and the connecting core rod are in interference fit, the damping needed by the hinge in the rotation process can be ensured. Due to the texture of the damping sleeves, the silence of the hinge in the rotation process can be ensured.

Description

technical field [0001] The invention relates to a hinge with damping, which belongs to the technical field of hinges. Background technique [0002] The hinges of the original technology all use damping oil to achieve uniform rotation force and quiet effect of the hinge. Since there is a certain amount of reasonable gaps in metal products, after the hinge is used for a certain period of time, the damping oil will overflow from the gap during the use of the hinge. , If there is no special degreasing agent or thin wetting agent, there is no way to wipe off the spilled oil, so the oil will absorb dust and sand and produce quite obvious oil stains, which will seriously affect the aesthetics of the product; due to the loss of damping oil, the hinge will be lowered Or the loss of damping function causes uneven rotation and poor hand feeling. Due to the loss of damping oil, the rotation fit between the leaf and the rotating shaft loses oil lubrication, resulting in friction noise b...

[0002] The hinges of the original technology all use damping oil to achieve uniform rotation force and quiet effect of the hinge. Since there is a certain amount of reasonable gaps in metal products, after the hinge is used for a certain period of time, the damping oil will overflow from the gap during the use of the hinge. , If there is no special degreasing agent or thin wetting agent, there is no way to wipe off the spilled oil, so the oil will absorb dust and sand and produce quite obvious oil stains, which will seriously affect the aesthetics of the product; due to the loss of damping oil, the hinge will be lowered Or lose the damping function, resulting in uneven rotation and bad hand feeling

Due to the loss of damping oil, the rotation fit between the leaf and the rotating shaft loses oil lubrication, resulting in friction noise between metal and metal; there is a certain gap between the inner wall of the hinge leaf coil and the connecting mandrel, due to The loss of oil will cause metal friction to increase the gap, which will cause the hinged door leaf to sag. In severe cases, the door leaf and the door frame cannot be closed normally, causing trouble to the user and economic loss to the door factory.

During the production and installation of the hinges, the damping oil is easy to stick to the hands, and it is not easy to clean. It must be cleaned with a special cleaning agent. Long-term use of such cleaning agents will cause certain damage to the workers themselves; the damping oil is injected during the installation process. It will cause the injection volume to be uncontrollable and the damping oil to be thin and thick due to the temperature difference, resulting in a certain waste of materials and a difference in the degree of hinge rotation.

The hinge of the original technology is locked by the friction force between the outer circle of the lower column of the cap head and the inner wall of the sheet coil tube to prevent the cap head from falling off. It has been proved by practice that the inner diameter of the sheet coil tube will increase after the hinge is used under load, so that the friction The reduction or disappearance of the force will cause the cap head to fall off, and the connecting mandrel of the hinge will also fall off after the cap head falls off, which will cause the single-claw leaf and double-claw leaf to disengage, thereby causing the door leaf and the door frame to disengage, which may seriously cause personnel injuries. casualties
