Abstract

The utility model provides a magnetic screen blind, which can prevent insects in particular mosquitoes and flies from invading indoors. The magnetic screen blind is mainly composed of a screen blind, a rolling and storing device, and a magnetic sealing device. The utility model which is suitable for any window (door) can completely solve the troubles caused by the insects such as mosquitoes, flies, etc.

Description

Magnetic screen blind

The utility model relates to a kind of insect, particularly mosquito, indoor device of fly intrusion of preventing.

Take precautions against at present mosquitos and flies and generally adopt screen door and window and pesticide, mosquito-repellent incense etc., the screen door and window effect is better, but has the expense height, and it is big to take up room, and installs and uses shortcomings such as trouble is fragile; Pesticide and mosquito-repellent incense are to air existence chemical contamination in various degree, and when the indoor-outdoor air discharge value was big, effect is sharply decline just, is difficult to reach the purpose of the trouble of thoroughly doing away with mosquitos and flies.

The utility model aims to provide mosquito and fly preventing device a kind of easy for installation, cheap, and it can solve the trouble of indoor mosquitos and flies up hill and dale.

The utility model is realized as follows: the top of yarn curtain is fixed on the interior take up roll of coiler device, the mode that coiler device combines with magnetic force with machinery or machinery (wooden doorframe is with following closely) is fixed on the top frame (or center) of door and window, the yarn curtain is walked around the underframe that deflector roll hangs down to door and window, its sagging length is subjected to the control of a ratchet, pull open ratchet, the yarn curtain is subjected to the wind spring effect, the tendency that automatic indentation case is arranged, yarn curtain edge with steel band (or magnetic strip of paper used for sealing) can be loaded on door, magnetic strip of paper used for sealing (or steel band) phase adhesive on the window frame, thereby make yarn curtain and doorframe and window frame keep sealing, when not in use, pull open ratchet, the yarn curtain is peeled off doorframe and window frame, get final product in the automatic rollback case, as not adopting volume to hide device, can hook be installed on yarn curtain top, promptly become the plain type Magnetic screen blind.

Main body of the present utility model--yarn curtain noise when opening and closing is extremely light, can need not occupy fixing unlatching space from movable sealing, and is easy for installation, can two-wayly push open and can bear to collide and can not damage.

Below in conjunction with embodiment the utility model is further described in detail:

Fig. 1 is the schematic diagram of the utility model embodiment 1.

Fig. 2 a, b are the schematic diagrames of the utility model embodiment 2.

With reference to Fig. 1: ratchet 1, take up roll 2, deflector roll 6 removable mountings are on end cap 11, back stop 12 removable mountings are between ratchet 1 and end cap 11, yarn curtain 7, wind spring 4, ratchet 5 all is installed on the take up roll 2, magnet steel (or steel folder) 10 is loaded on the end cap 11, yarn curtain 7 is walked around deflector roll 6 and is hung down to the underframe of doorframe, the edge of yarn curtain 7 is with steel band (or magnetic strip of paper used for sealing) 8, door corresponding with it, magnetic strip of paper used for sealing (or steel band) 9 is housed on the window frame, because the mutual adhesive of steel band 8 and magnetic strip of paper used for sealing 9, yarn curtain 7 and door have been guaranteed, the sealing of window frame, thereby prevent mosquito effectively, fly, insect is invaded indoor, wind spring 4 has makes yarn curtain 7 be involved in the effect of case 3 automatically, but owing to the restraining of ratchet 1 is positioned on the desired position.

With reference to Fig. 2 a: the edge of yarn curtain 13 is with magnetic strip of paper used for sealing 15,1/3 place, bottom dress handle 14, hook 16 is loaded on the top of yarn curtain 13, will link up with the 16 top frames that are hung on Door and window frame, magnetic strip of paper used for sealing 14 just with doorframe (or be loaded on the wooden sash steel band) adhesive mutually; Make the sealing of yarn curtain and Door and window frame.

With reference to Fig. 2 b, will link up with 16 and be loaded on and the corresponding position of transom window underframe, and install steel folder 17 additional near frame place, transom window top to adapt to the dress extension needs of steel sash.
