Description

Windproof roller blind

Technical Field

The utility model belongs to kind are used for open-ended protection device, and curtain is rolled up to type of concretely relates to kind prevent wind.

Background

The rolling curtain , also called rolling gate , is rolling curtains 0 with multiple joints moving in series , in the fixed slide way, 2 rotating up and down with the rolling shaft above 1 as the center, the rolling curtain 3 is almost rolling curtain 5 of the device in the manufacturing enterprise or workshop, the rolling curtain 6 has a lot of calendar history abroad, also in the last ten years, it is introduced into China slowly, the rolling curtain 7 has good fire-proof and anti-theft function, the safety performance is high, and many food and medicine industry warehouses are isolated by using the rolling curtain , the rolling curtain is seen to be really in place in the safety aspect, the rolling curtain is now 4 widely applied to public places or houses such as commercial surface, garage, market, hospital, factory and mining enterprise, etc., especially hole is bigger, the place inconvenient for installing body plays a role of convenient and fast opening.

The rolling curtain has the same function as wall and has horizontal separation, and is composed of curtain board, seat board, guide rail, support, reel, box, control box, rolling machine, limiting stopper, lintel, manual quick-release switch device, button switch and safety device, etc. is installed at the position where the partition is not convenient.

The rolling curtain is divided into a manual rolling curtain and an electric rolling curtain 0 according to the opening mode, an inorganic cloth rolling curtain 2, a grid rolling curtain 3, an aluminum alloy rolling curtain 4, a crystal rolling curtain 5, a stainless steel rolling curtain , a color steel plate rolling curtain , a reinforced wind-resistant rolling curtain and the like according to the 1 sheet material, an upward rolling curtain and a side rolling curtain according to the opening direction, and a common rolling curtain , a wind-resistant rolling curtain , a fireproof rolling curtain , a quick rolling curtain , an electric Australian (silent) rolling curtain and the like according to the application.

The design of the existing rolling curtain on the market has no wind resistance function, the bottom end of the rolling curtain is basically inserted into frames directly or is in contact with the ground, when the existing rolling curtain is attacked by strong wind, the rolling curtain 0 bends and deforms under the action of the wind, meanwhile, the pulling force which is given to the edge of the rolling curtain 1 to be separated from frames is increased gradually along with the increase of the wind, when the wind reaches the limit of 2 (strong wind), the strong pulling force pulls the edge of the rolling curtain out of frames, so that the whole rolling curtain is separated from frames, the rolling curtain cannot be used, and for the rolling curtain which is in contact with the ground only, the wind resistance capability is more insurmountable in impact.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a roll up curtain that exists and do not possess anti-wind ability or the weak shortcoming of anti-wind ability and propose in order to overcome prior art, its purpose provides prevent wind type and rolls up curtain.

The technical scheme of the utility model is that:

A windproof type roller blind comprises a roller box arranged above a frame, rails arranged on two sides of a frame, a roller shaft arranged in the roller box, a end of the roller shaft connected with a driving mechanism, a roller blind upper end wound and fixed on the roller shaft, a ground groove comprising a lock catch groove buried in the ground and a connecting groove arranged above the lock catch groove and with the upper portion extending out of the ground, wherein the bottom surface of the connecting groove and the top surface of the lock catch groove are same end surfaces and are provided with notches, the long edge of the top end of the connecting groove is bent inwards to form a C-shaped lock catch position, a lock catch is arranged in the lock catch groove, the lock catch is G-shaped, the opening end of the lock catch corresponds to the notches, a J-shaped lock hook is arranged at the bottom end of the roller blind, and at least lock catches.

The cross section of the outer wall of the scroll is in a regular polygon shape, and the cross section of the inner wall of the scroll is in a circular shape.

The driving mechanism is fixed above the frame.

The bottom surface and each side surface of the lock catch are fixedly connected with the lock catch groove.

The top end of the lock hook is inserted into the bottom end of the roller shutter and is in interference connection with the roller shutter.

The bending direction of the lock hook is opposite to the bending direction of the opening of the lock catch.

The side of the latch hook facing away from the hook head is coplanar with the side wall of the roller blind.

The utility model has the advantages that:

the utility model provides a curtain is rolled up to types of prevent wind type, hasp in the hasp groove closes with setting up in the latch hook of rolling up the curtain bottom, the realization is to the fixed of rolling up the curtain, set up simultaneously in the fixture block of rolling up the curtain bottom and the dual function of the long limit edge incurve formation C type buckle position in the top of spread groove, guarantee when receiving strong wind to strike, no matter how big wind-force is, roll up curtain and how take place bending deformation, the edge of rolling up the curtain is hasp all the time at the ground inslot, can not throw off, thereby make the performance of rolling up curtain anti-wind improve greatly, ensure to roll up curtain and still can use as usual when receiving the wind.
