Description
Technical field
The utility model belongs to door knob technical field, is related to a kind of air spring door knob.
Background technique
When opening, door is influenced arbitrarily to rotate door by external force in order to prevent, is set between the lower backside and metope of common door
Door knob is set, current door knob mainly passes through magnet suction and suction base and suction two components of column are pulled together to fix at door
Firmly, when being attracted such as when the fast speed of door rotation, the sound of shock is issued between suction base and suction column, and be easily damaged door
Touch the service life for influencing door knob.
To solve this problem, the technical staff in field uses soft material part in the impact head of door knob, in this way can
Achieve the effect that mute.Applicant improves on this basis, further increases the buffering effect of door knob.
Summary of the invention
The utility model aiming at the above problems existing in the prior art, provides a kind of air spring door knob, this is practical new
Type the technical problem to be solved is that: how to improve door knob buffering effect.
The purpose of this utility model can be realized by the following technical scheme:
A kind of air spring door knob, including pedestal are installed with soft impact head, the soft collision at the top of the pedestal
There is cushion chamber in head, the elastic component resetted for controlling soft impact head is equipped in the soft impact head, which is characterized in that
The inner face of the pedestal, which has, to be axially extended to extraneous air flue, and the cushion chamber is connected with the air flue.
Pedestal can be horizontally fixed in metope, bottom surface or door body, and soft impact head is connected on pedestal, in soft impact head
Interior setting cushion chamber, when door knob work, soft impact head is by collision deformation and compresses cushion chamber, and compression buffering cavity space is simultaneously
It compresses internal gas and absorbs momentum, to realize buffering effect, the cross-sectional shape of soft impact head can be round, oval
Or other polygon moulding, the interior elastic component being arranged of cushion chamber are resetted for controlling soft impact head deformation, preparation collision next time, when
So, door knob also can be used alone, and only play buffer function.By the way that air flue is arranged in the inner end of pedestal, and make air flue and cushion chamber
Connection, the smooth discharge of energy after being compressed of such air dielectric guarantee buffering effect and are avoided that soft impact head transition is swollen
It is swollen and be lost.
In above-mentioned air spring door knob, impingement plate is installed at the top of the soft impact head.By being touched soft
The top setting impingement plate ramed, can be driven entire soft impact head to deform by impingement plate, expand and become when door knob collides in this way
Shape region avoids deformation area too small and influences service life and buffering effect.
In above-mentioned air spring door knob, the bottom of the soft impact head is connected with mounting plate, the mounting plate with
The pedestal is connected, and has gas vent up and down on the mounting plate, and the gas vent is connected to the cushion chamber and air flue.It is logical
Cross the bottom in soft impact head and mounting plate be set, in this way convenient for realizing stable assembly by mounting plate and pedestal, by
Gas vent is set on mounting plate, guarantees that door knob operates normally.
In above-mentioned air spring door knob, the bottom surface of the impingement plate has the gag lever post extended downward, the limit
The lower end of bar has limiting section, and the lower end of the gag lever post through the gas vent and can be such that the bottom surface of limiting section and mounting plate limits
Against.Soft impact head has preferable elasticity, persistently by after the effect of elastic component may deformation excessively and influence stroke and
Moulding makes the limiting section of gag lever post end through gas vent by the way that gag lever post is arranged in the bottom surface of impingement plate, and gag lever post is arranged
It can be limited with mounting plate against in this way when soft impact head resets time limit position portion to a certain extent and peace under the action of the elastic member
Loading board is against making soft impact head not continue to reset deformation, improve using effect and service life.
Alternatively, the bottom surface of the impingement plate has the gag lever post extended downward, the lower end of the gag lever post
With limiting section, the inner edge of the air flue has gear edge, and the lower end of the gag lever post is inserted in the air flue and can make limiting section
With gear edge bottom surface limit against.The lower end that gag lever post is arranged is inserted in air flue and makes the limiting section and air flue that limit boom end
Interior gear is along bottom against in this way when soft impact head resets time limit position portion to a certain extent and gear edge under the action of the elastic member
Limit makes soft impact head not continue to reset deformation, improves using effect and service life.
In above-mentioned air spring door knob, the radial dimension of the air flue is greater than the radial dimension of the limiting section.It is logical
The radial dimension for crossing setting air flue is greater than the radial dimension of limiting section, and guarantee limiting section in this way will not block air flue always, make door
Touch normal work.
In above-mentioned air spring door knob, the elastic component is located in the cushion chamber and is sheathed on the gag lever post
Periphery.By the way that by elastic component setting, in cushion chamber, then the periphery by the way that elastic component to be sheathed on to gag lever post in this way can be to elasticity
Part generates certain positioning limit effect, guarantees that door knob buffering effect is stablized.
In above-mentioned air spring door knob, the soft impact head is rubber parts, silica gel part or plastic part.Rubber material
Or elasticity is good for silica gel material, long service life, has better buffering effect, production of plastics parts is at low cost.
In above-mentioned air spring door knob, the elastic component is pressure spring, damper rod or air spring.Pressure spring or damper rod
Convenient for assembly, improves production efficiency and guarantee reset effect.
Compared with prior art, as follows the advantages of the utility model:
1, this air spring door knob is by being arranged air flue in the inner end of pedestal, and is connected to air flue with cushion chamber, empty in this way
Gas medium smooth discharge of energy after being compressed, avoids soft impact head excessive expansion and is lost.
2, this air spring door knob, in this way can be by when door knob collides by the way that impingement plate is arranged at the top of soft impact head
Impingement plate drives entire soft impact head deformation, and enlargement deformation region avoids deformation area too small and influences service life and ease up
Rush effect.
