Abstract
The utility model relates to a novel sealing device for bus floor manholes. The device is composed of a manhole frame (2) and an entire manhole cover (5), wherein the manhole frame is fixedly mounted at the edge of a manhole and made of entire polyurethane hard foaming materials, and the entire manhole cover (5) which is made of polyurethane hard foaming materials is fitly fastened to the manhole frame (2); an insulating and noise reducing material layer (1) is filled below and around the manhole frame. The insulating and noise reducing material layer (1) is filled below and around the manhole frame of the utility model, the insulating and noise reducing material layer is adhered to an aluminum plate, and the manhole frame is installed in the manhole, so that the heat and the noise produced by a bus can be sealed and insulated; the manhole cover is covered, and the manhole cover is fastened to the manhole frame through a fastening bolt, so the heat and the noise can be further sealed and insulated. The device of the utility model can effectively prevent the heat and the noise from transferring into the bus, and the passengers on the bus can be more comfortable. In addition, the utility model has the advantages of beautiful appearance, simple structure, and convenient examine and repair for maintenance staff.
Description
Technical field
The utility model relates to a kind of new type passenger car floor access hole sealing arrangement.
Background technology
The access hole that is provided with on the bus deck mainly be make the maintainer to fuel tank, back axle and driving engine overhaul, more convenient when keeping in repair, easy, but, the access hole that is provided with on the bus deck also can bring some negative effects usually, the access hole that is provided with on the floor can make the sealing property around the access hole descend, noise and heat will be delivered in the car around access hole, internal car noise increase, temperature are risen, and because the floor maintenance flap that is provided with on the present passenger vehicle, mostly adopt aluminium section bar to add wood covering, its sealing, noise reduction and heat-proof quality are all not ideal.
The utility model content
The purpose of this utility model is to provide a kind of new type passenger car floor access hole sealing arrangement, to improve its sealing, noise reduction, effect of heat insulation.
In order to achieve the above object, the technical solution of the utility model is to have adopted a kind of new type passenger car floor access hole sealing arrangement, this device constitutes by being fixedly mounted on the fastening integral body maintenance flap made from rigid polyurethane foams that coincide on access hole frame that access hole makes along the hard expanded material of last integral polyurethane, the access hole frame, is filled with heat insulation acoustic damping materials layer around below the access hole frame.
Described maintenance flap is assemblied in the frame of access hole frame along on the seam table top, is equipped with at least one rubber weather strip between the fitting surface between maintenance flap and the seam table top, and the maintenance flap is fastened on the access hole frame by binding bolt.
In the access hole of described maintenance flap below also lining be placed with the heat insulation noise reduction layer that constitutes by the heat insulation acoustic damping materials layer of pasting on the aluminium sheet at top and the aluminium sheet bottom surface.
Because the access hole frame that is made of the hard expanded material of integral polyurethane of the present utility model is fixedly mounted on access hole along last, be filled with heat insulation acoustic damping materials layer around access hole frame following, heat insulation acoustic damping materials layer is bonded on the aluminium sheet, the access hole frame is put into access hole, thereby seal isolated heat and the noise that passenger vehicle produced; Cover the maintenance flap, and will overhaul flap and be fastened on the access hole frame by binding bolt, it is isolated that heat and noise are carried out enhanced leaktightness.Device of the present utility model has stoped the transmission in car of heat and noise effectively, and is more comfortable when making the passenger take passenger vehicle.In addition, the utility model is handsome in appearance, and is simple in structure, also greatly facilitates the maintainer simultaneously and overhauls.
Description of drawings
Fig. 1 structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, bus deck access hole sealing arrangement of the present utility model, by being fixedly mounted on the access hole frame 2 that access hole is made along the hard expanded material of last integral polyurethane, the fastening integral body maintenance flap made from rigid polyurethane foams 5 that coincide on the access hole frame 2 constitutes, be filled with heat insulation acoustic damping materials layer 1 around below access hole frame 2, maintenance flap 5 is assemblied in the frame of access hole frame 2 along on the seam table top 8, be equipped with rubber weather strip 4 between the fitting surface between maintenance flap 5 and the seam table top 8, maintenance flap 5 is fastened on the access hole frame 2 by binding bolt 3, in the access hole of maintenance flap 5 belows also lining be placed with the heat insulation noise reduction layer that constitutes by the heat insulation acoustic damping materials layer of pasting on the aluminium sheet 6 at top and aluminium sheet 6 bottom surfaces 7.
During use, earlier access hole frame 2 is fixed on the access hole of floor, then below access hole frame 2 around stuffed heat insulated acoustic damping materials 1, then heat insulation acoustic damping materials 7 are bonded on the aluminium sheet 6, put into access hole, seal isolated first to heat and noise; Covering maintenance flap 5 at last also is fastenedly connected with binding bolt 3, in maintenance flap 5 and access hole frame 2 engagement process, rubber weather strip 4 plays sealing function, and it is isolated that maintenance flap 5, access hole frame 2, rubber weather strip 4 and 3 pairs of heats of binding bolt, noise carry out enhanced leaktightness.
Claims (3)
