Abstract
The utility model discloses a soft-rigid door seal which is characterized by comprising a door seal body made of hard modified plastics and an anti-collision layer made of soft modified plastics. The reinforcing end is arranged on the door seal body integrally, a through hole formed along the length direction of the door seal body is formed in the reinforcing end, and the surface of one side of the reinforcing end is combined with the anti-collision layer. The soft-rigid door seal has the advantages of being low in cost and long in service life under the condition that the strength is not reduced.
Description
Technical field
The utility model relates to a kind of gasket, especially relates to a kind of soft or hard gasket.
Background technology
Gasket is the significant components on elevator, and the gasket symmetry is arranged on the end of left side elevator door and right side elevator door, and when the elevator door of arranged on left and right sides closed up, the gasket on left side and right side fitted, and plays the effects such as sealing, crashproof, shading and decoration.Existing gasket generally adopts metallic framework, and as aluminum alloy framework, stainless steel insert etc., cost is higher, and easily producing under external force permanent deformation affects sealing effectiveness and service life.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, provide that a kind of cost is low, the soft or hard gasket of long service life.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the soft or hard gasket, comprise the gasket body of being made by the hard modified plastics and the crashproof layer of being made by soft modified plastics, on described gasket body, be wholely set and strengthened end, in described reinforcement end, be provided with along the through hole of described gasket body length direction, a side surface of described reinforcement end is mutually compound with described crashproof layer.
Preferably, the end face of described crashproof layer is zig-zag, concavo-convex or L shaped shape.After the elevator door of arranged on left and right sides closed up, the end face of the crashproof layer on the arranged on left and right sides gasket fitted, and the fitting area of the end face of jagged crashproof layer is larger, can play better sealing, shading and crashproof effect.
Preferably, a side surface of described reinforcement end is plane.When a side surface of strengthening holding is plane, be conducive to simplify the production technology of gasket, be easier to moulding and compound.
Preferably, a side surface of described reinforcement end is curved surface.When a side surface of strengthening holding is curved surface, larger with the compound area of crashproof layer, thereby can being compounded in more firmly, crashproof layer strengthens end above, further extend the service life of gasket.
Preferably, the opposite side of described reinforcement end surface is inclined-plane.The opposite side surface of strengthening end is inclined-plane, can play better buffer action, extraneous impact by crashproof layer transmission is decomposed by this inclined-plane, and is less thereby pass to the power of gasket body end, therefore further improved the crashproof effect of the utility model gasket.
Compared with prior art, the utility model has the advantage of: the utility model soft or hard gasket, on the gasket body, be wholely set and strengthened end, strengthen being provided with along the through hole of gasket body length direction in end, this through hole is when playing cushioning effect, can also increase the intensity of gasket, reduce simultaneously the materials of gasket; Again due to the gasket body by the hard modified plastics make, crashproof layer made by soft modified plastics, adopts the hard modified plastics to substitute traditional metallic material, and the cost of gasket is greatly reduced; Modified plastics is difficult for producing permanent deformation, and service life is longer.Visible, the utility model soft or hard gasket, do not falling under low intensive condition, and cost is lower, longer service life.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment soft or hard gasket.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in the figure, the soft or hard gasket, comprise the gasket body 1 of being made by the hard modified plastics and the crashproof layer 2 of being made by soft modified plastics, the end face 21 of crashproof layer 2 is zig-zag, on gasket body 1, be wholely set and strengthened end 11, strengthened being provided with along the through hole 3 of gasket body 1 length direction in end 11, a side surface 12 of strengthening end 11 is mutually compound with crashproof layer 2, and the side surface 12 that should strengthen end 11 is plane, and the opposite side surface 13 of strengthening end 11 is inclined-plane.
In above specific embodiment, except plane, a side surface 12 of strengthening end 11 also can be curved surface, with the compound area of increase reinforcement end 11 with crashproof layer 2, makes crashproof layer 2 to be compounded in more firmly on reinforcement end 11, further extends the service life of gasket.
Claims (5)
1. soft or hard gasket, it is characterized in that comprising the gasket body of being made by the hard modified plastics and the crashproof layer of being made by soft modified plastics, on described gasket body, be wholely set and strengthened end, in described reinforcement end, be provided with along the through hole of described gasket body length direction, a side surface of described reinforcement end is mutually compound with described crashproof layer.
2. soft or hard gasket according to claim 1, is characterized in that the end face of described crashproof layer is zig-zag, concavo-convex or L shaped shape.
