Description

The directed retractable door of self-enclosed ground slot type

The utility model relates to door, is the directed retractable door of a kind of self-enclosed ground slot type concretely.

Automatically retractable door is a kind of class product that generally uses.The guiding device of the automatic retractable door that present each class manufacturer makes, a kind of is as guide rail or guide ribs with angle steel, circle bar, square steel etc., its spacious disease is that guide rail and guide ribs are after installation, obviously above ground level, a kind of roadblock of artificial formation, it is normally current promptly to influence the vehicle of overslaugh again attractive in appearance.Another kind is to be embedded in underground with " " type channel-section steel, and its worn-out disease is empty in " " type channel-section steel, very easily shelters evil people and countenance evil practices, and easily ponding after finger stone is bumped in the groove, directly influences the door running body.At northern area, after ponding froze, the door body can't move at all.And to remove foreign material in the groove, and time-consuming again taking a lot of work, too frequent again.

The present utility model purpose is in order to solve the problem that slot type directed retractable door automatically in above ground exists, to propose the directed retractable door of a kind of self-enclosed ground slot type, it is not being influenced under the normal passage situation of vehicle, can guaranteeing that the door body normally moves.

In order to realize goal of the invention of the present utility model, the utility model adopts following scheme: the directed retractable door of a kind of self-enclosed ground slot type, comprise a sheet, hinge bar and be positioned at a directive wheel of sheet lower end, with the corresponding ground of directive wheel movement locus on the guiding geosyncline is housed, its special character be the guiding geosyncline interior space in be filled with elastic filler.

Specifically above-mentioned elastic filler can select for use regime of elastic deformation 20～30% can be high temperature resistant, low temperature resistant, the high molecular polymer that does not absorb water.

Furtherly, described door sheet is made up of front column, rear column and crossbeam, in the top and the bottom of the front surface of front column the unequal length decoration panel is housed respectively, links to each other by a brace between rear column and the crossbeam.

Furtherly, described door sheet is made up of front column, rear column and crossbeam, and rectangular, is linked to each other by plug connector between them.

Furtherly, described hinge bar can have three groups or four groups, and they are vertical and are arranged in parallel.

Door body of the present utility model is when normal operation, and the directive wheel that is contained under the mainframe box makes the filler elastic deformation under the door action of gravity, to lower compression.And after filler was left in the directive wheel motion, filler restored to the original state under elastic force effect own at once.Like this, just guaranteed that filler is to be in spatiality in the full geosyncline of filling all the time, prevented that finger stone, dust, foreign material, ponding etc. from falling in the geosyncline, reached the normal operation purpose that guarantees the door body.

It is convenient that the utility model is installed, changed, and cost is low, and good reliability is especially filled elastic filler in the guiding geosyncline, can make the guiding geosyncline the same with ground high at ordinary times, do not influence passing through of pedestrian and vehicle, can guarantee the normal unlatching of a body again.Be applicable to various retractable doors.

Further specify the utility model below in conjunction with accompanying drawing.

The utility model mainly by the door body, be arranged in a directive wheel of body lower end 1 and with the corresponding guiding geosyncline 3 that is installed in ground of this directive wheel 1 movement locus.Be filled with elastic filler 2 in the interior space of guiding geosyncline 3, referring to Fig. 1 and Fig. 2, this elastic filler selects for use regime of elastic deformation at 20～30% high temperature resistant, the low temperature resistant high molecular polymer that does not absorb water, as specific rubber etc.It can make moulding in advance, embeds in the guiding geosyncline 3, also can in-site pouring, coagulation forming.When directive wheel 1 in door running body process be contained in guiding geosyncline 3 in the elastic filler 2 in space when contact, elastic filler 2 directive wheel 1 and action of gravity under downward elastic deformation.Do not have the contact position at filler 2 and directive wheel 1, filler 2 is still keeping and the contour original state in guiding geosyncline 3 surfaces under self resilient force.Reach and prevent that effectively foreign material, ponding from becoming finger stone to fall in the geosyncline, normally moves a body.

Described door body is made up of door sheet 4 and hinge bar 5, sees Fig. 3 and Fig. 4.Hinge bar 5 has three groups, be vertical and be arranged in parallel, and mass activity is hinged, and it has enriched the supporting force of the abundant degree and the door sheet of door body.

Described door sheet 4 can adopt composite door sheet or monomer-type door sheet.The composite door chip architecture is seen Fig. 5, Fig. 6, and it is made up of front column 41, rear column 42 and crossbeam 43.The decoration panel 44 of unequal length is housed respectively in the top and the bottom of front column 41 front surfaces, links to each other by brace 45 between rear column 42 and the crossbeam 43.This composite door sheet has tangible third dimension, and ornamental is strong.

Monomer-type door chip architecture is seen Fig. 7, Fig. 8, and it is made up of front column 41, rear column 42 and crossbeam 43, and is rectangular, connects as one by plug connector 46 between forward and backward column and the crossbeam.

Unite the above, structure of the present utility model, outward appearance are not only novel, and being installed under the situation that neither influences vehicles and pedestrians of elastic filler, can guarantee the normal operation of a body again, than background technology tool substantive distinguishing features and obvious improvement.
