Description
Technical field
The utility model relates to the elevator door sealing band.
Background technology
The elevator door sealing joint strip can play the effect of buffering, crashproof, sealing, shading, decoration.Now, the structure of sealing joint strip is varied, has also produced different forming processs according to different sealing joint strip structures.Is that open day of 2005.9.16 discloses a kind of Lift Car Door Hall Door Sealing Strip And Shaping Process in the patent documentation of 2007.11.28 as the patent No. for the ZL200510060790.3 applying date.Sealing band comprises that being installed in elevator two fans the hard soft modified PVC layer that is embedded with skeleton that matches on the doors of the car gate Room, described skeleton is the stainless steel substrates or the cold rolling steel disc of flow forming, be positioned at described hard modified PVC layer one end that match and be embedded with soft modified PVC layer, and described two soft modified PVC layers that match have the contact surface that matches.Though the sealing band of this structure can be realized the basic function of elevator sealing band, but, skeleton to be embedded in the hard modified PVC layer, in extrusion molding, it is good to carry skeleton, the hard modified PVC of injection and inject will the work good quality that could guarantee product of soft modified PVC three, therefore, having relatively high expectations to moulding; In addition, when soft modified PVC layer deforms, be that change has taken place the interior tissue of material, in deformation process, there is mutual restriction between the material structure, therefore, deflection can only reach the ultimate deformation amount of material itself, as surpassed the ultimate deformation amount, then become plastic deformation, therefore, screen resilience reduces, have, because deflection is limited, the shake-proof ability of sealing band is relatively poor again.
Summary of the invention
The purpose of this utility model provides a kind of elevator door sealing joint strip, and technical matters to be solved is to simplify the forming process of sealing joint strip, improves the shock resistance of sealing joint strip, improves the screen resilience of sealing joint strip.
For achieving the above object, the elevator door sealing joint strip comprises that the installation sheet by the rigid plastic moulding reaches and installation sheet one end bonded assembly sealing head, and described sealing head has a sealing surface, has the axis shock relieve vent parallel with sealing surface on the sealing head.
Sealing joint strip of the present utility model, because installation sheet is only by the rigid plastic moulding, when the moulding sealing joint strip, with rigid plastic and nonrigid plastic simultaneously pressure injection in mould and extrusion molding get final product, with respect to prior art, do not need rigid plastic to be embedded in skeleton, therefore, simplify the technology of moulding, reduced the cost of moulding; In addition, owing to be provided with shock relieve vent, like this, sealing head distortion trailing portion material has been filled in the shock relieve vent, therefore, the deflection of sealing head can be very big, good damping effect, and, after squeese pressure was cancelled, the screen resilience of sealing head was also big, for extruding antidetonation has next time been established basis preferably.
As improvement, on sealing head, be positioned at a side that contacts with elevator door and be formed with protrusion.When being installed to sealing joint strip on the elevator door, protrusion deforms, produce squeese pressure between sealing joint strip and the elevator door and can not produce the gap, the steadiness that sealing joint strip is fixed on the elevator door is good, in addition, when the fastener that is used to install sealing joint strip takes place because protrusion has rebound action, also can guarantee sealing joint strip and elevator door closed contact when loosening.
As improvement, on installation sheet, be positioned at installation sheet and the sealing head junction is provided with dovetail furrow, sealing head is provided with the jut of holding in the dovetail furrow.Like this, being connected firmly of sealing head and installation sheet is not easy to separate the service life of having improved sealing joint strip.
As improvement, installation sheet is provided with mounting hole.Mounting hole is set is convenient to install sealing joint strip.
