Abstract
Elevator gasket, it is related to a kind of elevator assistant product.Including gasket body and the anticollision layer made of soft modified rubber made of hard modified plastics, fixed between gasket body and anticollision layer by heating coextru-lamination, it is arranged to strengthen end in the side of the gasket body close to anticollision layer, one side and the anticollision layer for strengthening end are mutually compound；It is to form groove to the raised fin in gasket body side face, the back side of fin to strengthen end, and fin or groove are set along the gasket main body length direction.This door seal structure is simple, it is easy to manufacture, and intensity is high, and service life length, anticollision, obturation effect are good, have close well it is compensatory.
Description
Technical field
It the utility model is related to a kind of elevator assistant product, more particularly to a kind of soft or hard gasket of elevator door.
Background technology
Gasket is the significant components on elevator, and gasket is symmetrically mounted on the end of left side elevator door and right side elevator door
Portion, when the elevator door of arranged on left and right sides closes up, the gasket on left side and right side fits, and plays sealing, anticollision, shading and dress
The effect such as decorations.Existing gasket typically uses metallic framework, such as aluminum alloy framework, stainless steel insert etc., and cost is higher, outside
Being also easy to produce permanent deformation under power effect influences sealing effectiveness and service life.
The existing soft or hard gasket as described by ZL201320358057.X, feature are：It is made including hard modified plastics
Gasket body and have anticollision layer made of soft perceptual plastics, be wholely set reinforcement end on gasket body, strengthened end
The through hole along gasket body length direction is inside provided with, the side surface for strengthening end is consistent with anticollision layer.This gasket exists
During processing, easy processing, more waste material, do not strengthen end and cause its excessive high hardness, use for a long time after finding deformation, elevator door closes
Hold together, both sides gasket is not easy to completely attach to, is bonded.
Utility model content
The defects of in order to overcome existing gasket, the utility model offer one kind is simple in construction, it is easy to manufacture, uses
Long lifespan, anticollision, obturation effect are good, close compensatory good elevator gasket.
The utility model includes the gasket body made of hard modified plastics and prevented made of soft modified rubber
Layer is hit, is fixed between the gasket body and anticollision layer by heating coextru-lamination, in the gasket close to the anticollision layer
The side of body is arranged to strengthen end, and the one side for strengthening end and the anticollision layer are mutually compound；The reinforcement end is to door
The raised fin in strip of paper used for sealing body side face, the back side of the fin form groove, and the fin or groove are along the gasket
Main body length direction is set.
Gasket main body of the present utility model is arranged to reinforcement end with anticollision layer connecting portion, strengthens the increase of end thickness, and
Be arranged to groove profile, it is compound that thickness increase is advantageous to anticollision layer, trench structure in the case of proof strength, facilitate machine-shaping,
Material is saved, meanwhile, it has certain deformation nature, is easy to the later stage to install, after long-term use, if shape occurs for gasket
Become, under self-compensation situation ability, the gasket of left and right elevator door is appointed can so close well；This door seal structure is simple, production
Easy to manufacture, intensity is high, and service life length, anticollision, obturation effect are good, compensatory with closing well.
Groove described in the utility model is square groove or circular groove.According to the shape of different strength demand selection grooves.
The utility model sets projection together with least on the contact surface compound with the anticollision layer of the reinforcement end, described
It is raised to be set along the gasket body length direction, in the raised embedded anticollision layer.In gasket main body and prevent
Hit and projection is set on the composite surface of layer contact, after heating coextru-lamination, contact area is bigger, and composite effect is more preferable, more firm
Gu anticollision layer is difficult for drop-off.
The utility model sets T-slot or V together with least on the contact surface compound with the anticollision layer of the reinforcement end
Type groove, the T-slot or V-groove are set along the gasket body length direction, the anticollision layer be embedded in the T-slot or
V-groove.Groove is set on the composite surface that gasket main body and anticollision layer contact, after heating coextru-lamination, contact area
Bigger, composite effect is more preferable, and more firmly, anticollision layer is difficult for drop-off.
The end face of anticollision layer described in the utility model is zigzag, concavo-convex.The fitting of the end face of jagged anticollision layer
Area is bigger, can play better seal, shading and anticollision effect.

Embodiment
As shown in Figure 1, 2, this elevator gasket, including the gasket body 1 and by soft made of hard modified plastics
Anticollision layer 2 made of modified rubber, is fixed between gasket body 1 and anticollision layer 2 by heating coextru-lamination, close to anticollision
The side of the gasket body 1 of layer 2 is arranged to strengthen end 3, and one side and the anticollision layer 2 for strengthening end 3 are mutually compound；Strengthening end 3 is
The fin 4 raised to gasket body side face, the back side of fin 4 form groove 5, and fin 4 or groove 5 are along gasket main body
1 length direction is set.Groove 5 is square groove or circular groove.According to the shape of different strength demand selection grooves.
Further, as shown in figure 3, setting projection 6 together with least on the contact surface compound with anticollision layer 2 of end 3 is strengthened,
Projection 6 is set along the length direction of gasket body 1, and projection 6 is embedded in anticollision layer 2.
Further, as shown in Figure 4,5, set on the contact surface compound with anticollision layer 2 of end 3 is strengthened T-shaped together with least
Groove 7 or V-groove 8, T-slot 7 or V-groove 8 are set along the length direction of gasket body 1, and anticollision layer 3 is embedded in T-slot 7 or V-type
Groove 8.
Further, the end face of anticollision layer 2 is zigzag, concavo-convex.
