Description

Stainless steel screen reel and invisible screen window structure

Technical Field

The utility model relates to the related field of invisible screen windows, in particular to a stainless steel screen scroll and an invisible screen window structure.

Background

The invisible screen window is automatically collected in no-mosquito seasons, does not occupy indoor space, does not influence lighting and viewing, has the characteristic of invisibility, and is deeply loved by consumers. The existing scroll type invisible screen window in the market mostly adopts nylon screen mesh or fiber mesh, and has the defects that: only can prevent mosquito and rat bite, and has poor weather resistance and wear resistance and short service life of the gauze.

The 304 stainless steel gauze has the characteristics of mosquito prevention, rat bite prevention, weather resistance, no rust, wear resistance and long service life, and is an ideal screen window manufacturing material. However, the existing 304 stainless steel screen is only used on the sliding window and the horizontally-opened inward-opening or outward-opening window, and cannot be applied to the roller type invisible screen window product, which is an unfortunate | for both consumers and manufacturers! The main reasons why the stainless steel screen mesh cannot be applied to the scroll type invisible screen window product are as follows: the stainless steel gauze has thicker and harder wire diameter and large gauze tension, the stainless steel gauze made of the coiled 304 material can be collected into the invisible gauze box, the spring torsion required by the flexible gauze can be dozens of times larger than that of the fiber gauze, the existing invisible gauze window reel cannot provide the acting force (spring torsion) required by collecting the stainless steel gauze made of the 304 material into the gauze box due to the structure, and the spring is powerful and has no place due to the structure of the reel.

To solve the problem, in the chinese patent application with application publication No. CN111206871A, the stainless steel screen made of 304 material can be rolled into a screen box by using an adjustable torsion spring to generate a larger pulling force, so that the stainless steel screen made of 304 material can be applied to a scroll type invisible screen window product. However, the screen does not have a damping function when being contracted, and can violently impact the screen box, so that the service life of the screen window is influenced.

Generally, after a certain period of time, the spring of the roll-type invisible screen window product is used, the spring is fatigued, the torsion of the spring is reduced along with the time, and the retraction of the screen is influenced because the recovery torsion of the spring is reduced. At this time, the spring needs to be finely adjusted, and the torsion of the spring is increased to realize the torsion of the stainless steel gauze during initial installation. When the spring is in fatigue and needs to be adjusted, the whole invisible screen window needs to be taken down, the limiting pin of the screen shaft is taken out, the torsion of the spring is adjusted through the inner hexagonal wrench, the limiting pin is inserted after the torsion is adjusted to a proper position, and the screen window is installed again. After a user uses the system for a certain time, professional technicians need to be informed to adjust the system (after-sales service of a manufacturer), inconvenience is brought to the user, and the manufacturer needs to pay additionally or the user bears after-sales service cost (such as wages of the technicians), so that time and labor are wasted; and the main end cover of the screen box in the prior art can not realize free adjustment of the spring torsion, and if the main end cover needs to be adjusted, the main end cover needs to be re-installed after being adjusted by the whole frame screen window, and can be realized by professional technicians.

In the design of handle latch fitting, adopt simple and easy latch fitting structure, take place to kick-back when the easy mistake touches, lead to automatic rolling, children miss touches and have the potential safety hazard.
