Description

Barometric hinge

Technical field

The utility model relates to a kind of hinge, and particularly a kind of combined type of pneumatic cylinder and flexible member that adopts designs, and has the Barometric hinge of laborsaving and buffering effect.

Background technology

Existing hinge means comprises: a holder is locked on the doorframe; One rotating seat is locked on the door-plate; One is connected part, is installed between said fixing seat and the rotating seat, in order to be connected and fixed seat and rotating seat; Positioning piece is installed between said fixing seat and rotating seat, with the above-mentioned part opposite side that is connected; One bolster is located at holder and is connected between the part.

When opening door-plate to an opening position, rotating seat drives keeper away from holder, and the bolster part that is positioned replaces, and makes bolster produce a restoring force that keeper is resetted; When closing door-plate, rotating seat is near holder, and drives keeper, makes the state that is positioned bolster part replaces remove, and discharges the restoring force of bolster, and then drive keeper and reset, and drive door-plate with this and move to the position of closing the door.

Above-mentioned existing hinge means, though can be at closing time, the restoring force that utilizes bolster to provide resets keeper, and drive door-plate to the position of closing the door, but in the process that resets,, make the also abrupt release of restoring force of bolster because the state of replacing of bolster removes suddenly, door-plate cuts out rapidly, easily cause the situation that weighs finger wounded to take place, and during door-plate collision doorframe, can produce the bigger sound, during long-term the use, easily cause the damage of door-plate and doorframe.

Another existing hinge, see the TaiWan, China patent announcement for details No. 508270, its structure is roughly same as described above, above-mentioned bolster is one to be installed in the gas and oil cylinder pressure of holder, after door-plate is opened, keeper will drive in the cylinder axle of gas and oil cylinder pressure and contract to the state of gas and oil cylinder pressure, with the restoring force that provides keeper to reset; At closing time, by above-mentioned restoring force, drive plate and slowly close, make the cylinder axle be the state that stretches out the gas and oil cylinder pressure.

This existing hinge, though can improve the shortcoming of above-mentioned quick closedown door-plate, owing to need the application of force overcome to continue in the gas and oil cylinder pressure restoring force that produces when opening the door, make and need expend bigger power when opening the door, when using for a long time, locking place of rotating seat and door-plate, easily produce and become flexible, damage door-plate.

The utility model content

Main purpose of the present utility model is to address the aforementioned drawbacks, and for avoiding the existence of this defective, the utility model provides a Barometric hinge, can make at closing time, and plate can not closed rapidly and be caused finger to weigh or produce the big sound wounded; And can not need when opening the door bestow bigger and lasting power and can open plate.

For achieving the above object, Barometric hinge of the present utility model provides a reset unit, comprises a flexible member, a supporting member, reaches a pneumatic cylinder; Utilize above-mentioned flexible member, in order to the restoring force that provides supporting member to reset; And

Above-mentioned pneumatic cylinder has one with the cylinder axis that can stretch into, the mode of stretching out is installed, and a termination of cylinder axis is located at above-mentioned supporting member, and the other end then connects with an adjustment valve and establishes; The outer wall of wherein adjusting valve is the thin shape of a central thick dual side-edge, and to stretch out the power of pneumatic cylinder little thereby make cylinder axis stretch into power that pneumatic cylinder takes.

When opening plate to opening position, supporting member is with the top above-mentioned flexible member of pulling, and flexible member will produce a restoring force that supporting member is resetted this moment, and supporting member will drive cylinder axis and stretch in the pneumatic cylinder; When closing plate, by above-mentioned restoring force, the drive supporting member resets, supporting member will drive cylinder axis and stretch out pneumatic cylinder this moment, make pneumatic cylinder produce a cushion effect that supporting member can slowly be resetted, make plate can slowly move to the position of closing the door by above-mentioned restoring force and cushion effect, plate is resetted fast with the restoring force of avoiding flexible member to be produced.
