Description
Technical field
The utility model is related to a kind of hydraulicefficiency hinges, and in particular to a kind of glass door hydraulicefficiency hinge.
Background technology
At present, in all kinds of places such as market, office building, station, people can be generally installed on glass door with work(of pulling back
The hinge clip of energy is used for the bounce-bit closed state automatic behind the door that will be opened.But existing Glass hinge screen resilience
Smaller, then return dynamics is inadequate, it is impossible to door leaf is retracted into closed position, it is necessary to additionally install floor spring exactly, and floor spring
Stringent to the requirement of bottom surface borehole size, easy install failure is very inconvenient.And be with after floor spring since screen resilience is larger,
Easily upon rebound so that reciprocating rotation occurs for door leaf, and it is possible that the user that wounds, there are security risks.It uses on the market at present
Glass door hydraulicefficiency hinge generally existing seating velocity it is too fast, and appear in increase wind speed or it is unexpected touch after, due to closing
Door excessive velocities and the problem of cause huge sound occurs at closing time.
Utility model content
In view of the deficiencies of the prior art, the utility model proposes a kind of glass door hydraulicefficiency hinge, resetting spring, oil are passed through
Reasonable cooperation between cylinder and annular knurl shaft can realize slow unlatching and the return of glass door, so as to fulfill glass door and door
Frame is without impact, voiceless sound, vibrationless closing effect.
To realize above-mentioned technical proposal, the utility model provides a kind of glass door hydraulicefficiency hinge, including fixed seat, activity
