Abstract

The utility model discloses a roller window screen. The fixed end of a screen net is fixed on a rotatable screen rolling tube and a mandrel tube in the screen rolling tube is inserted between an upper and a lower fixed seats and is arranged on one side of a window frame or a wall by a fixed part. The rolling up and down and the tension of the screen net are achieved by the spring which is arranged between the mandrel tube and the screen rolling up tube. The free end of the screen net is fixed to a clamp bar on the edge of the screen net, and the clamp bar on the edge of the screen net is fixed to the window frame by an upper and a lower window following fixed frames which are arranged on both ends of the clamp bar on the edge of the screen net. The installation and operation of the screen window are flexible and convenient, and the opening size of the screen window can be regulated freely, which needs not being disassembled because of the seasons change. The screen net is tightly stretched on an inner window frame because of the action of the spring. The utility model has the advantages of favorable mosquito proof effect and long service life.

Description

Roller window screen

The utility model belongs to the building window technical field, relates in particular to a kind of novel roll type screen window.

The screen window that generally uses of people is generally wooden frame structure or aluminum alloy frame structure in daily life, these screen windows all are to be provided with separately outside the structure of window, gauze stretches tight in window frame, the aluminium alloys screen window that is applied at present on the various modern architecture things generally all is plug-type screen window, this screen window is that the screen window fan directly is fixed on the slideway of aluminum alloy push-pull window, to occupy the slideway of casement during use, influence moving of casement, this class screen window all needs installation and removal when changing according to the season, depositing of screen window is also very inconvenient; Though people have gained some understanding to the screen window of rolling voluntarily, this screen window often all need be provided with sealing device, structure more complicated separately on window frame.

The purpose of this utility model will overcome the deficiency of above-mentioned prior art exactly, and a kind of Shi Buxu of changing according to the season dismounting, compact conformation, simple novel winding drum formula screen window are provided.

The purpose of this utility model is achieved in that this roll type screen window comprises gauze auto reeling part, gauze, parts such as gauze limit clamp bar, the main feature of its structure is that the gauze auto reeling partly is at the two ends of core tube clockwork spring to be housed, one end of clockwork spring is fixed in the core tube, the other end is fixed on the volume spool that is inserted in outside the core tube, the installed inside of clockwork spring has the catch spring cover, the outside respectively by on hold interstage sleeve, under hold interstage sleeve and fix, the fixed end of gauze is fixed on the rotating volume spool of coiling gauze, the free end of gauze is fixed on the clamp bar of gauze limit, and the two ends of gauze limit clamp bar are separately installed with the window upper holder with the window lower fixed frame.Be covered with the reel guard shield of cylindrical shell in the outside of volume spool, the cross section of reel guard shield can be U-shaped, the two ends of reel guard shield have upper fixed seat and lower fixed seat respectively, and core tube is fixed on upper fixed seat and the lower fixed seat, press the gauze central siphon to be fixed between the lower fixed seat.

The utility model roll type screen window draws back sash owing to be provided with automatic winder and with the upper and lower fixed mount of window, can make the interlock of sash and gauze, and gauze stretches out thereupon, the formation screen window; Shut sash, gauze is rollback thereupon, does not influence the open and close of former sash, and is very easy to use.Owing to used clockwork spring in the gauze automatic winder, compact conformation not only, and also because the tension force of spring stretches tight on interior window frame gauze tightly.

The utility model roll type screen door structure is reasonable in design, and applicability is strong, daily Maintenance free maintenance, and cost is low, and the life-span is long, is convenient to install, and is safe and reliable.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Referring to Fig. 1～Fig. 5, roll type screen window of the present utility model includes gauze auto reeling part, gauze (14), gauze limit clamp bar parts such as (12), the gauze auto reeling partly is at the two ends of core tube (5) clockwork spring (3) to be installed, one end of clockwork spring (3) is fixed in the core tube (5) with rivet, core tube (5) outside is with volume spool (6), the other end of clockwork spring (3) is inserted and secured on the volume spool (6), the installed inside of clockwork spring (3) has catch spring cover (4), hold on the outside interstage sleeve (2) and under hold interstage sleeve (8) and pack into and roll up between spool (6) and the core tube (5), connect volume spool (6) with screw, form reel.The gauze auto reeling partly is located in the window frame of one side, the fixed end of gauze sticks with glue and connects on the rotating volume spool (6) that is fixed on the coiling gauze, the free end of gauze sticks with glue and connects or be fixedly clamped on gauze limit clamp bar (12), by insert at the two ends of gauze limit clamp bar (12) with window upper holder (11) be connected with the frame of sash with window lower fixed frame (10), make gauze volume, putting can be with the pass of sash, open interlock, the size that the regulated at will screen window is opened.

Referring to Fig. 6～Figure 12, with screw fixing upper fixed seat (1) on window frame or the wall, lower fixed seat (9), core tube (5) is inserted in upper fixed seat (1) and the lower fixed seat (9), press gauze central siphon (13) also to be inserted on upper fixed seat (1) and the lower fixed seat (9), gauze (14) on volume spool (6) volume, the free end of gauze (14) passes through on pressure gauze central siphon (13), be covered with the reel guard shield (7) of cylindrical shell in the outside of volume spool (6), the cross section of reel guard shield (7) is a U-shaped, with screw reel guard shield (7) is fixed between upper fixed seat (1) and the lower fixed seat (9).

Cylindrical shell as reel guard shield (7) in the gauze auto reeling part both can adopt the also available aluminum alloy materials of plastics, gauze limit clamp bar (12), press gauze central siphon (13) and core tube (6) to adopt aluminum alloy materials, last lower fixed seat (1) and (9), catch spring cover (4) and hold interstage sleeve (2) up and down and (8) and make with lower fixed frame on the window (11) and (10) employing plastics.

During use, with being fixed on the window frame of gauze limit clamp bar (12) two ends with lower fixed frame on the window (11) and (10), when sash is opened, drive gauze stretches out thereupon, form screen window, because the effect of spring is stretched tight on interior window frame gauze tightly, this moment, the clockwork spring of 65Mn steel (3) was tightened and storage power along with the rotation of reel; When closing sash, clockwork spring (3) releases energy, and reel arrives gauze rollback again on the volume spool (6) under the effect of spring.
