Abstract

The utility model relates to a novel shutter hinge joint structure. The improvement of the structure of the joint part of each door hinge lies in that the joint part is in a point contact way and is swung in a circular arc shape; the mutual interference caused by sliding friction of the joint parts of all the door hinges can be avoided when a shutter is rolled and unrolled, the smoothness of the rolling and unrolling of the shutter can be improved, and jarring noise can be lowered.

Description

Closure structure for rolling door

The relevant a kind of rolling door structure of the utility model refers in particular to a kind of new-type rolling door gate flap connected structure.

Though the rolling door of prior art can be promoted household or the merchant etc. of battalion facility in life, roll up when unreeling, can produce huge noise usually, even disturb and neighbours household's peacefulness.

Main purpose of the present utility model provides a kind of new-type rolling door gate flap connected structure, promotes the rolling door volume and puts the smooth and easy of action, and avoid huge noise to produce.

The purpose of this utility model, the principal character that is had is: the improvement gate flap is the two ends connected structure up and down, the convergence part is suitable up and down is reverse positive barb, and form a flange and a depression respectively in the corresponding appropriate location of two hooks, several gate flaves by this structure of tool wear the convergence part up and down mutually, form whole rolling door, when batching or draw when putting sheet, the joining place of each gate flap is the contact of approximate point and makes arc swing, reduce the phenomenon that the mutual sliding friction of each gate flap joining place disturbs, it is smooth-going that the enhancement volume is put action, reduces the generation of thorn ear noise.

The utility model compared with prior art has and promotes volume to put action smooth-going, reduces advantages such as thorn ear noise.

Fig. 1 is existing rolling door gate flap connected structure sectional drawing.

Fig. 2 is the utility model section of structure.

Fig. 3 is the utility model embodiment schematic diagram.

With reference to shown in Figure 1, Fig. 1 is existing rolling door connected structure, when the full wafer rolling door of structure string group volume is put thus, the positive barb that each page gate flap is connected mutually, with the start of face friction mode, or, send the huge ear-piercing sound because of roll-forming is connected the difference of cheicers degree or has the sliding friction interference phenomenon to produce during because of factors such as articulated section gap lengths.

With reference to shown in Figure 2, convergence part 12 was constituted under the utility model was reached by convergence part on gate flap body 1 gate flap 11; Wherein uplink portion is the free-ended positive hook of a tool, the hook end is forked 111, the bent angle A1 of inboard formation, the convergence part then is reverse free-ended barb under the gate flap, and in inboard nearly middle place's formation one flange 121 of hook, the flange top is taper A2, and the angle of bent angle A1 is slightly larger than the angle of cone A2; Gate flap by this structure of tool wears the full wafer rolling door (as Fig. 2-1) that the string group is become up and down mutually, when the rolling door elevator, the doudle leaf door leaf of its adjacent connection is the convergence part up and down, because the angle A 1 of fork inboard, positive hook hook end is by 121 supporting roles of barb inward flange, when the rolling door volume is put, can make hook end fork in the mode of near point with contact, work freely swings to dead point, flange both sides beginning and ends (seeing Fig. 3 embodiment schematic diagram), it is the contact friction area that the utility model can reduce adjacent gate flap convergence part, the sliding friction interference phenomenon produces when avoiding moving, and prevents to produce a thundering noise when volume from unreeling.

Claims

1, a kind of new-type rolling door log type gate leaf and its, by the gate flap body, convergence part on the gate flap, the convergence part constitutes under the gate flap, it is characterized in that the convergence part is suitable up and down is reverse positive barb, and form a flange and a depression respectively in the corresponding part of two hooks, wear the convergence part up and down mutually by the number gate flap of this structure of tool, form whole rolling door.

2, new-type rolling door log type gate leaf and its according to claim 1 is characterized in that the convergence part is a free-ended positive hook, and the hook end is forked, the bent angle of inboard formation, the convergence part is reverse free-ended barb under the gate flap, and the inboard nearly middle place of hook forms a flange, and the flange top is taper.
