Abstract
The utility model discloses a kind of rolling door, comprise spool, the first cord, the second cord and collet, described spool external surface is provided with bearing at equal intervals, described bearing is provided with the framework be lifted on by bearing on beam, described first cord and the second cord are symmetricly set on immediately below described spool, and described first cord is fixedly connected with described collet with the bottom of described second cord.This rolling door can apply the occasion with door opening span, and intensity is large, long service life.
Description
Technical field
The utility model relates to a kind of rolling door.
Background technology
Rolling door (rolling-gate) is cascaded with the door sheet of multi-joint activity, in fixing slideway, above door, rotates upper and lower door centered by spool.Rolling door equally plays horizontal subdivision with the effect of wall, it is put the parts such as switching device, press button and safeties formed by curtain plate, seat board, guide rail, bearing, spool, casing, door-rolling machine, lintel, manual speed, is generally arranged on the position that inconvenience adopts wall to separate.Rolling door is applicable to public place or the houses such as the business shop front, garage, market, hospital, industrial enterprise.Especially door opening is comparatively large, and convenient, fast unlatching effect is played in the place of inconvenient installation ground door body.If when the span of door opening is larger, spool easily roughly caves in because the weight of bearing is excessive.
Utility model content
For solving above-mentioned prior art Problems existing, the utility model proposes a kind of rolling door, this rolling door can apply the occasion with door opening span, and intensity is large, long service life.
The technical solution of the utility model is achieved in that
A kind of rolling door, comprise spool, the first cord, the second cord and collet, described spool external surface is provided with bearing at equal intervals, described bearing is provided with the framework be lifted on by bearing on beam, described first cord and the second cord are symmetricly set on immediately below described spool, and described first cord is fixedly connected with described collet with the bottom of described second cord.
Further, described bearing is rolling bearing.
Further, the distance between described bearing is 1 meter.
Further, be symmetrically arranged with the rope sheave passed for steel cable below described spool, described steel cable one end is fixed on above described spool, and the other end is fixedly connected with described collet through described rope sheave.
The beneficial effects of the utility model:
Rolling door of the present utility model is provided with bearing at equal intervals by spool external surface, and the peripheral frame hoisting made by angle steel of bearing is contained in above beam, increases the supporting role of spool, reduces the load of spool, be less likely to occur to cave in.Moving up and down of cord is facilitated by arranging of steel cable.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model rolling door;
Fig. 2 is Fig. 1 lateral view.
Accompanying drawing indicates: 1, spool, the 2, first cord, the 3, second cord, and 4, collet, 5, bearing, 6, framework, 7, steel cable, 8, rope sheave.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See figures.1.and.2, a kind of rolling door, comprises spool 1, first cord 2, second cord 3 and collet 4.Described spool 1 external surface is provided with bearing 5 at equal intervals, and described bearing 5 is preferably rolling bearing.Distance between described bearing 5 is preferably 1 meter.Described bearing 5 is provided with the framework 6 be lifted on by bearing 5 on beam, which increases the supporting role of spool 1, reduces the load of spool 1, be less likely to occur to cave in.Described first cord 2 and the second cord 3 are symmetricly set on immediately below described spool 1, and described first cord 2 is fixedly connected with described collet 4 with the bottom of described second cord 3.
Further, in the present embodiment, be symmetrically arranged with the rope sheave 8 passed for steel cable 7 below described spool 1, described steel cable 7 one end is fixed on above described spool 1, and the other end is fixedly connected with described collet 4 through described rope sheave 8, facilitates moving up and down of cord.Further, be provided with perforation above cord, this perforation is passed for steel cable 7.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (4)
