Abstract

The utility model relates to a no hinging integral coiling door in particular suitable for the doors or windows of a storehouse, a shop or a workshop. The utility model has changed the defect that a traditional coiling door is provided with a hinging point. A semi-wave shape portiere is molded and formed by roll extrusion of an integral color steel plate. And the inner side and outer side of the portiere are respectively provided with an adhesive tape with better tensile strength and flexibility. The utility model has the advantages of flexible use, difficult deformation, stable portiere running, good sealing and beautiful appearance.

Description

There is not hinged whole rolling door

The utility model belongs to a kind of rolling door, is specially adapted to the door or the window of warehouse, shop, factory floor etc.

Present rolling door has several, and a kind of is the traditional type rolling door, and being hinged by some curtain sheets is combined into an integral body, this structure is used dumb, yielding, and noise is big, sealing is poor, at this situation, revealed whole hinge-less rolling door, be 00234076.3 as the patent No., name is called " hinge-less overall structure rolling door ", this rolling door is made up of door curtain, doorframe track and reel, and door curtain is the whole door curtain of the dihedral convex-concave shape of tool, and door curtain is equipped with adhesive tape inside and outside the both sides.

The utility model provides a kind of hinge-less that is more suitable for practical another kind of shape to connect whole rolling door.

The utility model is made up of door curtain, doorframe track and reel, it is characterized in that door curtain is is the plane by the one side that block of metal materials processing is made, and another side is the curtain sheet of half-wave shape, the hinge-less contact.

Be separately installed with tensile strength and pliability band preferably inside and outside the door curtain of the present utility model both sides, be the half-wave shape on the door curtain half-wave shape adhesive tape vertical direction on one side.

The utility model uses flexibly, and not yielding, door curtain operates steadily, and good seal performance can not produce noise during switching, and has good decoration effect.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 looks schematic diagram for the utility model door curtain master.

Fig. 2 is the utility model door curtain schematic rear view.

Fig. 3 is the utility model door curtain lateral view.

1-power transmission shaft among the figure, 2-band, 3-door curtain, 4-reel.

The door curtain of rolling door described in the utility model is made half-wave shape 3 by whole color steel sheet roll forming, the elastic stress that the utility model utilizes material to be produced in process furls to be put, thereby reach open and close purpose freely, external force during for the gravity that overcomes door curtain and open and close is to the influence of elastic stress, cause the door curtain distortion, tensile strength and pliable and tough all adhesive tapes (2) preferably are installed in the both sides of door curtain, the gravity of door curtain and breakdown and when closing power act directly on the adhesive tape, reduce the load-bearing of door curtain geometry, thereby reached indeformable purpose.

In order to prevent that in the dust inlet chamber, rubber boot has been adopted in the rolling door lower edge.Reel of the present utility model adopts whole transmission, can determine the quantity of reel according to the size of fabric width, reel and power transmission shaft are synchronized with the movement, spiral cylindrical torsion spring is adopted at the power transmission shaft two ends, one end of spring connects with the support of bearing, the other end connects with reel, twisting resistance directly acts on the axle, make axle and the rotation of reel body, to putting purpose to volume, this structure has remedied the torsional moment inconsistent defective of spring because of caused by factors such as processing technology, material, heat treatment, thereby makes a body even running.Door running body track and spool shaft bearing end plate are that the component by moulding combine, adopt the location fastener to connect, track can about adjust, can be according to the size of doorframe, determine the length of track, and make suitable curtain plate, erection procedure is simple and convenient, the assembly precision height, spool shaft can remain on one preferably on the horizontal level, the inboard buffering acoustical liner that adopts plastic material to make with door body contact site of track has been eliminated the door body because of open and close and because wind or people push away the noise that the metal bump friction of generation is produced.

Claims

1, no hinged whole rolling door is made up of door curtain, doorframe track and reel, it is characterized in that door curtain is that the one side of being made by block of metal materials processing is the plane, and another side is the curtain sheet of half-wave shape, no pin joint.

2, no hinged whole rolling door according to claim 1 is characterized in that being separately installed with inside and outside the door curtain both sides all bands preferably of tensile strength and pliability, and the adhesive tape of door curtain half-wave shape one side also is the half-wave shape in vertical direction.
