Abstract
An automatic reset swinging door belongs to the filed of fixed architecture. A door leaf swing damping is additionally arranged, an installation position of a sealing wool top between a door side and a door frame is changed, thus overcoming the defects of quick return, big impact, easy loosening and exposed grinding cracks of components of the swinging door. The automatic reset swinging door comprises a door leaf, a door frame, a door leaf positioning and return hinge shaft. The improvement is that damping oil is filled in the space of the two ends of an inner positioning and return supporting column of a positioning and return hinge shaft bushing block, an oil through which is communicated with the two ends of the positioning and return supporting column is opened inside the wall of the bushing block, a flow control valve is arranged on the oil through. An overpressure hole and a pressure release hole are arranged on the bushing block or the supporting column. A sealing wool top installation groove is arranged on the arc surface of the door side. The invention has the positive effects that: thrust on a roller by the supporting column is eased, so that the automatic return movement of the door leaf is stable and gentle, thus reducing impact on the hinge shaft and possible collision on the pedestrians, lengthening the service life of the automatic positioning and return swinging door and improving security in use thereof.
Description
Technical field
The invention belongs to the fixed buildings field, be specifically related to pendulum type door.
Background technology
Into and out of the many public places of number, adopt self-reset pendulum type door more.Its structure comprises doorframe, door leaf, door leaf is hinged on elasticity reset device on the doorframe.The early stage elasticity reset device two-tube angle spring hinges that adopt more.Though two-tube limb spring hinge energy door leaf is hinged on the automatic resilience that also can realize door on the doorframe and cuts out, but spring hinge intensity is low, yielding, the damage in long back service time, door is bigger in the displacement of doorway horizontal direction in the open and close process, need between unlatching side door limit and doorframe, to interspace in advance the sealing performance of influence door.
The recent automatic location that is embedded in the doorjamb both ends of the surface and the hinge that resets that occurs, and cooperate hinge one side door limit identical with the arc surface of relative doorframe, to improve the sealing of door when closing, its technical scheme is documented among the Chinese patent ZL2004200269522, concrete structure is by lining, one end stretches into the centration axis of lining, and the location in the lining, return apical axis and apical axis compression spring are formed.End fixed lateral roller shaft in the centration axis lining, roller shaft two ends dress roller, the end face of location, return apical axis and roller contact jaw has the roller groove of square crossing, high infraversion malposition, and the angled transition face is arranged between the roller groove of intersection.Though this kind located automatically and the hinge that resets can realize that door driveing to the location of final position and fastening position and auto-reset function after breaking away from final enable possition.But door leaf swing undamped, swing speed can't be adjusted, and increases very fast at the reseting procedure medium velocity, suddenly stop during to fastening position, hinge is formed greater impact power, strengthen the wearing and tearing of the hinge of locating automatically, reset, easily make the fixedly generation of hinge and door leaf, doorframe loosening.In addition, the seal weatherstrip between the convex arc surface Men Bianyu concaved circular cambered surface doorframe of door-hinge one side all is mounted on the concaved circular cambered surface of doorframe, and service time is long slightly, forms the polishing scratch that exposes on the door leaf limit, influences the attractive in appearance of door.
Summary of the invention
A kind of self-reset pendulum type door is provided on the purpose of the present invention, set up the door leaf damping of oscillations, and the installation site of the seal weatherstrip between the transposing Men Bianyu doorframe, overcome existing self-return pendulum type door return speed fast, impact big, as to quicken articulated element wearing and tearing, easily loosening and produce the shortcoming that exposes polishing scratch.
The present invention includes the door leaf of existing self-reset pendulum type door, doorframe, the hinge between door leaf and the doorframe.Hinge wherein comprises and is installed in door leaf one end by lining, one end stretches into the centration axis of lining, the transverse axis of centration axis end in the lining, be installed in the roller at transverse axis two ends, end face in the lining has location, the return top supporting column of the roller groove of square crossing, high infraversion malposition, compression spring and centration axis is enclosed in location, the return main hinged shaft that the lining end cap in the lining forms and is installed in the secondary hinge that axostylus axostyle is only arranged of the door leaf other end and is installed in axle bed on the doorframe.The improvement that location, return hinge are done is: be full of damping oil in the space at location, return top supporting column two ends in lining, in jacket wall, have the oil through that is communicated with location, return top supporting column two ends, the axostylus axostyle of secondary hinge is contained in the sliding sleeve, between sliding sleeve and the axostylus axostyle compression spring is arranged, the bar shaped open-work is arranged on the sliding sleeve, on the axostylus axostyle of the bar hole position of corresponding sliding sleeve pit is arranged.More than be basic scheme of the present invention.
Improvement to the seal weatherstrip installation site between the Men Bianyu doorframe of door leaf hinge one side is: establish sealing wool top installation groove on the arc surface of the door leaf limit of door leaf hinge one side.
For ease of the flow of adjustment damping oil unit interval between location, return top supporting column two ends, select the damping dynamics, further improvement of the present invention is to be provided with flow control valve on oil through.
For preventing that door leaf is when being subjected to excessive, too quickly external force, oil pressure is too high in the lining, impair sealing ring and make hinge and the fixed place of door leaf, doorframe produces bigger moment of torsion and causes loosening, another improvement of the present invention is on the lining He on the top supporting column superpressure relief hole to be arranged, and the sphere that spring holds or the relief valve of plunger shape spool are arranged on the relief hole.
Good effect of the present invention is: locating by damping oil, the damping of mobile generation at top supporting column two ends resets, the mild thrust of top supporting column pair roller, make door leaf steady, soft in the self-return motion, when having reduced the return location to the impact of hinge and to the issuable bump of pedestrian, prolonged automatic location, the application life of the pendulum type door that resets and use in safety.
