Abstract
The utility model discloses a connecting structure of an access hole cover and an access hole. The connecting structure comprises the access hole which is arranged on an automobile floor and the access hole cover which corresponds to the access hole. The connecting hole cover and the access hole are in threaded connection, and a sealing structure is arranged between the access hole cover and the access hole. Compared with a common access hole cover which is in glue connection, mounting and dismounting of the access hole cover and the access hole which are in threaded connection are very simple, and meanwhile, the sealing structure which can improve the sealing property of the entire structure is arranged between the access hole cover and the access hole, and the good sealing property is guaranteed.
Description
Technical field
The utility model relates to a kind of maintenance lid, relates in particular to a kind of connection structure of overhauling lid and access hole.
Background technology
At present, the maintenance lid is as an important subsystem in the Full Vehicle System, its structure of appropriate design and mounting means, property easy for installation has important effect during to the maintenance of car load, common maintenance lid all is to link together by the mode that is coated with glue and the access hole on the automotive floor panel, the constant intensity of this connection mode is not enough, when the maintenance lid is subject to the collision of foreign object or extruding etc., the maintenance easy landing of lid or the slit occurs and have a strong impact on air-tightness, need again after the maintenance lid of this kind structure dismounting simultaneously when bonding, need to clean first access hole and the joint face that overhauls lid, and then be coated with glue, whole process is very numerous and diverse, has a strong impact on the work efficiency of maintenance.
Chinese patent Granted publication number: CN2808689Y, August 23 2006 Granted publication day, a kind of sealing device for bus floor manhole is disclosed, consist of by being fixedly mounted on the fastening integral body maintenance lid made from rigid polyurethane foams of coincideing on access hole frame that access hole makes along the hard expanded material of upper integral polyurethane, the access hole frame, be filled with the heat-insulation noise-reduction material layer around below the access hole frame.The heat-insulation noise-reduction material layer is bonded on the aluminium sheet, the access hole frame is put into access hole, thereby it is isolated that the heat that passenger vehicle is produced and noise seal, and the maintenance lid is connected with access hole by the mode that is coated with glue, heat and noise carried out enhanced leaktightness completely cut off.Its weak point is, maintenance lid in this structure still adopts the mode that is coated with glue to be connected with access hole, when needing again to assemble after the dismounting of maintenance lid, need to clean first access hole and the joint face that overhauls lid, and then be coated with glue, whole process is very numerous and diverse, has a strong impact on the work efficiency of maintenance.
The utility model content
The utility model is connected the dismounting that causes overhauling lid in order to overcome maintenance lid of the prior art and the access hole mode by gluing, it is all pretty troublesome to install, have a strong impact on the deficiency of leak tightness and overhaul efficiency, a kind of dismounting is provided, quick and convenient overhaul efficiency height, simultaneously the maintenance lid of good airproof performance and the connection structure of access hole have been installed.
To achieve these goals, the utility model adopts following technical scheme:
A kind of connection structure of overhauling lid and access hole, comprise the access hole that is arranged on the automotive floor panel and the maintenance lid corresponding with access hole, described maintenance lid is threaded with described access hole, is provided with hermetically-sealed construction between described maintenance lid and the access hole.The maintenance lid that is connected with common gluing relatively, Assembly ﹠Disassembly is all very simple between the maintenance lid that is threaded and the access hole, overhauls simultaneously the leak tightness that hermetically-sealed construction between lid and the access hole can increase total, guarantees that leak tightness is good.
As preferably, extend outward several auricles around the described maintenance lid, described auricle is provided with connecting bore, corresponding position with connecting bore around the described access hole is provided with fixed orifice, be provided with bulged tube in the described fixed orifice, described maintenance lid is threaded with bulged tube by self-tapping screw.First bulged tube is inserted in the fixed orifice from the outside of fixed orifice, then cover the maintenance lid, tighten fixingly by self-tapping screw, install simply, detachable is turned on self-tapping screw and get final product, the overhaul efficiency height.
Scheme arranged side by side, extend outward several auricles around the described maintenance lid, described auricle is provided with connecting bore, corresponding position with connecting bore around the described access hole is provided with fixed orifice, be provided with lining in the described fixed orifice, be provided with tapped bore in the described lining, described maintenance lid is connected with bush threads by bolt.First lining is put in from the inboard of access hole and fix with fixed orifice, cover the maintenance lid, bolt tightening, simple in structure, the installation and removal of maintenance lid are all very convenient.
As preferably, be provided with elastic seal ring between described maintenance lid and the access hole, described elastic seal ring consists of hermetically-sealed construction.Elastic seal ring is an annular ring, is located between access hole and the maintenance lid and plays sealing function, also has simultaneously the effect of vibration-absorbing denoising.
As preferably, the middle part of the described maintenance lid formation support chamber that upwards arches upward is provided with the sound insulation rubber layer in the described support chamber.Support chamber can strengthen the intensity of maintenance lid itself, is collided and is not easy when impacting to be out of shape, and the sound insulation rubber layer has the effect of noise reduction.
Therefore, the utlity model has dismounting, quick and convenient overhaul efficiency height, the beneficial effect of good airproof performance are installed.
