Description

The mosquito-proof door of roller shutter type

The utility model relates to the member of building---door, especially a kind of door with mosquito-proof net.

Now general mosquito-proof door is the mosquito-proof door of fan-shaped hinge type on the market, this mosquito-proof door can as door equally beat to open or close and close, but this door is too big with the fit clearance of doorframe, mosquito, worm can fly into or climb in the door from the gap.In addition, also have a kind of mosquito-proof door of frame type, open, close and close mosquito-proof door and all will move heavy mosquito-proof framework, use very inconveniently, and occupation space is bigger.Except above-mentioned two kinds outdoors mosquito-proof, also has the mosquito-proof door of a kind of easy curtain falling type, it hangs up netted holding court from behind a screen on common doorframe, beat the purpose that Push And Release closes mosquito-proof door by rolling or put down to hold court from behind a screen just can reach, this mosquito-proof door is simple, convenient, but owing to hold court from behind a screen too big with the doorframe gap, mosquito, worm are easy to fly into or crawl in, in addition, roll this operation by hand of holding court from behind a screen, use very inconvenient.

The purpose of this utility model provide a kind of mosquito-proof, worm is effective, and the mosquito-proof door of the mosquito-proof wire side of automated cleaning is arranged again.

The utility model comprises silk screen, left tray, right carriage, the networking lower strip, the automatic curtain device, wedge and two vertical guide rails, the automatic curtain device is between left tray and right carriage, the automatic curtain device comprises band internal tooth axle sleeve, gear shaft, torsion spring and two Support Gears, left tray and right carriage respectively have a mandrel, two Support Gears are enclosed within respectively on these two mandrels loosely, the tight cover of the axle of one end of torsion spring and gear shaft, the other end of torsion spring and the mandrel of right carriage tightly overlap, band internal tooth axle sleeve entangles two Support Gears, and entangle gear shaft between these two Support Gears, the internal tooth of band internal tooth axle sleeve and the external tooth of these two Support Gears, the external tooth of gear shaft is meshed, the outer circumference surface of band internal tooth axle sleeve is connected with an end of silk screen, and the other end of silk screen is connected with the networking lower strip; Two ends of networking lower strip have respectively one with the lower strip vertical guide rail vertical and that have the spill guide groove that networks, two ends of networking lower strip insert respectively in the spill guide groove of these two vertical guide rails, there is a wedge-shaped slot rear surface at the networking lower strip, in the rear surface of two vertical guide rail spill guide groove bottoms the elasticity wedge is installed all; The hairbrush bar is equipped with on spill guide groove two limits at two vertical guide rails, in networking lower strip bottom the hairbrush bar is housed, and between left tray and right carriage the hairbrush bar is housed.When the lower strip that networks was pulled to the vertical guide rail end, the elasticity wedge inserted the networking wedge-shaped slot of piece bar down, and at this moment, the elasticity wedge is locked the lower strip that networks, and the silk screen that links to each other with the networking lower strip is opened.If the networking lower strip is drawn towards the place ahead along continuous straight runs, at this moment, the networking lower strip will leave wedge, and under the effect of automatic curtain device, silk screen can be rolled-up rapidly.

Below in conjunction with drawings and Examples the utility model is described in further detail.

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

Fig. 2 is the partial sectional view of present embodiment automatic curtain device.

Sectional drawing when Fig. 3 is elasticity wedge locking networking lower strip.

Fig. 4 is the sectional drawing of networking lower strip when leaving the elasticity wedge.

With reference to Fig. 1, Fig. 2, Fig. 3, the automatic curtain device comprises band internal tooth axle sleeve 13, two Support Gears 9, gear shaft 10 and torsion spring 12, the tight cover of the axle of one end of torsion spring 12 and gear shaft 10, the mandrel of the other end of torsion spring 12 and right carriage 5 tightly overlaps, the upper end of silk screen 2 is connected on the cylindrical weekly form of band internal tooth axle sleeve 13, during installation, earlier silk screen 2 is twisted on the external peripheral surface of band internal tooth axle sleeve 13, then band internal tooth axle sleeve 13 is enclosed within on two Support Gears 9, gear shaft 10 between two Support Gears 9 is also entangled, the internal tooth of band internal tooth axle sleeve 13 and the external tooth of two Support Gears 9, the external tooth of gear shaft 10 is meshed.The networking lower strip 1 that links to each other with silk screen 2 lower ends when handle is when drop-down, networking lower strip 1 drives silk screen 2 and down moves, and silk screen 2 drives 13 rotations of band internal tooth axle sleeve, at this moment, the Support Gear 9 that is enclosed within the Support Gear 9 on left tray 4 mandrels loosely and is enclosed within loosely on right carriage 5 mandrels all rotates, gear shaft 10 between two Support Gears 9 also rotates, rotation along with gear shaft 10, also twisting thereupon of the tight torsion spring 12 that overlaps of axle with gear shaft 10, and the other end of torsion spring 12 tightly overlaps with right carriage 5 mandrels of fixing, the twisting of torsion spring 12 1 ends, and the other end is motionless, and then torsion spring 12 has stored rotational energy and do to have promoted silk screen 2 usefulness that moves upward.Two ends at networking lower strip 1 have a vertical guide rail 3 perpendicular and that have the spill guide groove respectively, two ends of networking lower strip 1 insert respectively in the spill guide groove of these two vertical guide rails 3, hairbrush bar 11 is equipped with on spill guide groove two limits of vertical guide rail 3, when pulled down is fixed on the handgrip 7 of networking lower strip 1, networking lower strip 1 down moves along the spill guide groove of vertical guide rail 3, and the hairbrush bar 11 that is installed in spill guide groove two limits of vertical guide rail 3 when networking lower strip 1 is down moved the center line along the spill guide groove move.When networking lower strip 1 was pulled to vertical guide rail 3 terminal, elasticity wedge 15 inserted the wedge-shaped slot 16 of networking lower strips 1, at this moment, elasticity wedge 15 locking networking lower strips 1, silk screen 2 is in opened condition.In addition; the hairbrush bar 11 that is installed in spill guide groove two limits of vertical guide rail 3 prevents in addition that with the hairbrush bar 11 that is installed in networking lower strip 1 bottom mosquito, worm from flying into or crawling into the effect in the door; the hairbrush bar 11 that is installed between left tray 4 and the right carriage 5 has the effect of cleaning silk screen 2; in order to protect torsion spring 12, pack into a torsion spring sleeve 14 at the excircle of torsion spring 12.

With reference to Fig. 1, Fig. 4, draw ear 6 towards the place ahead along continuous straight runs, at this moment, drawing ear 6 to drive networking lower strip 1 moves towards the place ahead along continuous straight runs, at this moment, 1 compressing of networking lower strip is positioned at the hairbrush bar 11 in the place ahead and leaves elasticity wedge 15, and the torsion spring 12 that has stored rotational energy drives band internal tooth axle sleeve 13 by gear shaft 10 and rotates, 13 rotations of band internal tooth axle sleeve then drive silk screen 2 rises rapidly, finishes the process of rolling silk screen 2.In addition, can prevent effectively that in order to make mosquito-proof door mosquito, worm from flying into or climbing in the door, mosquito-proof door preferably is installed on the door 8 of any surface finish.
