Abstract

The invention provides a curly sun-shading curtain with spring steel sheet capable of automatic furl. The sun-shading curtain is produced by sticking pre-curled and formed high-elasticity thin steel sheet to sun-shading cloth. The thin steel sheet can not only enhance strength of the sun-shading curtain, but also automatically furl the sun-shading curtain by virtue of curl elasticity of the thin steel sheet. The thin steel sheet can be stretched to be as wide as the sun-shading curtain to obtain better strength.

Description

The abat vent that furls with the coiled springs steel disc

Affiliated technical field

The present invention relates to a kind of abat vent, the abat vent that the spring steel plate that especially a kind of usefulness is curled furls automatically.

Background technology

Solar protection devices at present commonly used is an awning, has fixing with foldable.Fixed can't packing up can not be regulated injecting of sunlight freely.Foldable awning lateral view is the folding fan-shaped structure, can pack up, but the puggaree folding is held back together when packing up, and is irregular, not attractive in appearance.The advantage of awning is that wind loading rating is strong.The outdoor sunshade that Chinese patent ZL93204220.1 and ZL98236615.9 announce has the sunshade effect, but does not also have wind loading rating or wind loading rating not strong.The outdoor sunshade resultant effect that Chinese patent ZL02253249.8 announces is good, and its shortcoming also is that the cord folding is held back together when packing up, and is irregular attractive in appearance.The scheme that Chinese patent application 200820107614.X provides can strengthen the intensity of abat vent and can fitly roll, but fails to make full use of the elasticity of steel disc, needs other retracting device, increases production difficulty and cost.

Summary of the invention

Technical problem to be solved by this invention is: the abat vent scheme that Chinese number of patent application 200820107614.X provides is improved, made sunshading curtain winding more convenient, produce and install simply, have enough intensity opposings to expose to the weather.

The technical solution adopted for the present invention to solve the technical problems is: the high resiliency stalloy on the abat vent is carried out rolling and heat treatment typing in advance, be processed into curly form, utilize the elastic force of the stalloy that curls to furl abat vent.

The invention has the beneficial effects as follows: the intensity of abat vent is good, and the elasticity that makes full use of stalloy furls automatically, does not need other retracting device, and compact conformation is produced simply, and is easy for installation, neat appearance.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

In the accompanying drawing, Fig. 1 is that the cord that posts the scrollwork steel disc of first embodiment of the invention launches schematic diagram.

Fig. 2 is the overall structure schematic diagram of first embodiment of the invention.

Fig. 3 is the overall structure schematic diagram of second embodiment of the invention.

In the accompanying drawing, 1. cord base fabric, 2. stalloy, 3. set bolt, 4. wall, 5. spool, 6. draw ring, 7. pull bar, 8. hook.

The specific embodiment

Below in conjunction with description of drawings the specific embodiment of the present invention: as shown in Figure 1, stalloy 2 is sticked on the cord base fabric 1, the stalloy 2 of vertical direction is finalized the design through rolling with heat treatment in advance, cord can roll under curling stalloy elastic force effect automatically, as shown in Figure 2, cord is fixed on the wall 4 of window top with set bolt 3, pulling pull bar 7 pulls down spool 5 by draw ring 6, and spool 5 is fixed together with the lower edge of cord, can launch cord downwards like this, tangle with hook 8, keep the deployed condition of cord, unclamp hook 8, cord is automatic rewinding under curling stalloy elastic force effect, thereby packs up abat vent.

Fig. 3 has showed second embodiment of the present invention, in this embodiment, stalloy 2 expand to abat vent with wide, being cord is made of the stalloy 2 that rolls with the heat treatment typing through in advance of full wafer, its intensity is better, as shown in Figure 3, cord is fixed on set bolt 3 on the wall 4 of window top, pulling pull bar 7, pull down spool 5 by draw ring 6, spool 5 is fixed together with the lower edge of cord, can launch cord downwards like this, tangles with hook 8, the deployed condition that keeps cord, unclamp hook 8, cord is automatic rewinding under the curling stalloy elastic force effect of full wafer, thereby packs up abat vent.

Claims (2)

1. abat vent that furls, mainly form by sunshade cord, spool, pull bar, hook, it is characterized in that: paste the high resiliency stalloy on the roller blind, the high resiliency stalloy rolls through in advance and is processed into curly form, utilizes the elastic force of the stalloy that curls to furl abat vent automatically.

2. abat vent according to claim 1 is characterized in that: the high resiliency stalloy that curls expand to abat vent with wide.
